DETAILED DESCRIPTION

At present, a plunger pump is usually mounted directly on a beam of a carrier (such as a fracturing truck), so as to work normally. However, in the long-term use of a plunger pump, the plunger pump is prone to damage or failure, so it needs to be replaced. Upon a plunger pump is directly mounted on a support beam, it is difficult to disassemble and maintain the plunger pump, and it is prone to damage the plunger pump during disassembly and assembly, thus increasing the damage probability of the plunger pump.

On the other hand, the mounting position of the plunger pump on the beam or the plunger pump base is relatively fixed, so that different sizes of plunger pumps need to adopt different mounting positions or different plunger pump bases, thus increasing the costs.

Therefore, the embodiments of the present disclosure provide a plunger pump base and a plunger pump device. The plunger pump base includes a support assembly and an extension assembly. The support assembly includes a top plate, a bottom plate and a support frame between the top plate and the bottom plate, the top plate and the bottom plate are oppositely arranged at an interval, and the support frame is respectively fixed with the top plate and the bottom plate. The extension assembly includes an extension block, a first telescopic mechanism and a second telescopic mechanism. One end of the first telescopic mechanism is rotatably connected to the extension block, the other end of the first telescopic mechanism is rotatably connected to the top plate, and the first telescopic mechanism is configured to extend or contract. One end of the second telescopic mechanism is rotatably connected to the extension block, and the other end of the second telescopic mechanism is rotatably connected to the bottom plate, and the second telescopic mechanism is configured to extend or contract. In the plunger pump base, the extension block can be used for bearing and fixing a plunger pump, and the extension block, the first telescopic mechanism and the second telescopic mechanism can form a triangular support mechanism with adjustable size. Therefore, upon the lengths of the first telescopic mechanism and the second telescopic mechanism being adjusted, the distance between the extension block and the support assembly will also change, so that it can be used for supporting and fixing plunger pumps of different sizes. In addition, the triangular support mechanism is stable in structure, thus providing stable support for the plunger pump. On the other hand, the plunger pump can be mounted on a beam of a carrier through the plunger pump base, without being disassembled directly on the beam, thus reducing the difficulty of disassembly and maintenance and reducing the damage probability of the plunger pump.

Hereafter, the plunger pump base and plunger pump device provided by the embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

Therefore, the second telescopic mechanism can extend and contract by rotating the second threaded rod. Of course, the embodiments of the present disclosure include but are not limited thereto, and the second telescopic mechanism can extend and contract in other forms.

For example, as illustrated inFIGS.3and4, the fifth threaded connection portion165and the sixth threaded connection portion166can be sleeves, and the inner walls thereof are provided with threads. Outer walls of the two ends of the second threaded rod152are provided with threads to respectively form the above-mentioned seventh threaded connection portion167and eighth threaded connection portion168, so that threaded connection can be realized.

FIG.5is a schematic diagram of another plunger pump base according to an embodiment of the present disclosure.FIG.6is a schematic diagram of an operation platform of a plunger pump base according to an embodiment of the present disclosure.FIG.7is a bottom view of an operation platform of a plunger pump base according to an embodiment of the present disclosure.

In some examples, as illustrated inFIGS.5-7, the plunger pump base100further includes an operation platform180, which is arranged adjacent to the support assembly110in a direction parallel to the top plate112(e.g., horizontal direction). The operation platform180includes a fixed portion182and a movable portion184. The fixed portion182is fixed with the support assembly110and extends in the direction away from the support assembly110. The fixed portion182is provided with a first sliding groove1820, and the movable portion184is slidably connected in the first sliding groove1820and configured to move in the extending direction of the first sliding groove1820. Therefore, the plunger pump base can provide an operation platform for maintenance personnel or repair personnel, thereby reducing the difficulty of maintenance and repair. In addition, because the movable portion of the operation platform can move in the extending direction of the first sliding groove, the space occupied by the operation platform can be increased and reduced by sliding the movable portion, thereby improving convenience.

For example, upon the carrier carrying the plunger pump base being transported, the movable portion can be slid to a position where the first sliding groove is close to the support assembly, that is, a position of the fixed portion close to the support assembly, so that the space occupied by the operation platform can be reduced, and transportation is facilitated. Upon the carrier carrying the plunger pump base being in maintenance, the movable portion can be slid to a position where the first sliding groove is away from the support assembly, that is, a position of the fixed portion away from the support assembly, which can provide a larger operating space for operators.

In some examples, as illustrated inFIG.5, the operation platform180and the extension assembly120can be located on two opposite sides of the support assembly110in a direction parallel to the top plate112(e.g., horizontal direction), so that the space on the two sides of the beam of the carrier can be fully utilized.

In some examples, as illustrated inFIG.5, the fixed portion182of the operation platform180can be fixed on the fixing assembly190by screws or bolts. Of course, the embodiments of the present disclosure include but are not limited thereto, and the fixed portion of the operation platform can also be fixed on other components of the plunger pump base.

In some examples, as illustrated inFIGS.5-7, the operation platform180includes two fixed portions182, and the movable portion184is located between the two fixed portions182, and a side of each fixed portion182close to the movable portion184is provided with the first sliding groove1820.

In some examples, as illustrated inFIGS.5-7, the operation platform180further includes a stopper186located on the fixed portion182and configured to limit the movement of the movable portion184. For example, upon the carrier carrying the plunger pump base being transported, the movable portion can be slid to a position where the first sliding groove is close to the support assembly, that is, a position of the fixed portion close to the support assembly, in this case, the position of the movable portion can be fixed by the stopper to prevent the movable portion from sliding in the first sliding groove. Upon the carrier carrying the plunger pump base being in maintenance, the movable portion can be slid to the position where the first sliding groove is away from the support assembly, that is, a position of the fixed portion away from the support assembly, in this case, the position of the movable portion can also be fixed by the stopper to prevent the movable portion from sliding in the first sliding groove.

For example, the stopper186can be a latch. Of course, the embodiments of the present disclosure include but are not limited thereto, and other forms of limiting structures can also be adopted for the stopper.

In some examples, as illustrated inFIGS.5-7, the movable portion184includes: a grid plate1842including a bearing surface18420configured to bear an operator; a second sliding groove1844located on the side of the grid plate1842away from the bearing surface18420; a ladder1846slidably arranged in the second sliding groove1844, and at least one end of the ladder1846is configured to move in the extending direction of the second sliding groove1844. Upon the plunger pump base being fixed on the carrier, the operation platform has a certain height from the ground, therefore, by accommodating the ladder at the bottom of the movable portion, the ladder can be pulled out when it needs to be used, so that it is convenient for maintenance personnel or repair personnel to board the operation platform through the ladder.

In some examples, as illustrated inFIGS.5-7, the operation platform180further includes an armrest188, which is located on a side of the movable portion184away from the support assembly110and is fixed on the movable portion184, thereby providing safety protection for maintenance personnel or repair personnel.

FIG.8is a schematic diagram of a ladder of a plunger pump base according to an embodiment of the present disclosure. As illustrated inFIG.8, one end of the ladder1846can also include a pull ring18462, which is convenient for the operator to pull the ladder1846out of the second sliding groove1844.

At least one embodiment of the present disclosure further provides a plunger pump device.FIG.9is a schematic diagram of a plunger pump device according to an embodiment of the present disclosure. As illustrated inFIG.9, the plunger pump device500includes a carrier300, a plunger pump base100and a plunger pump200. The carrier300includes a beam310, and the plunger pump base100is fixed on the beam310. The plunger pump200is fixed on the plunger pump base100. Therefore, the plunger pump base can be used for supporting and fixing plunger pumps of different sizes, and can provide stable support for the plunger pumps. On the other hand, the plunger pump can be mounted on the beam of the carrier through the plunger pump base, without being disassembled directly on the beam, thus reducing the difficulty of disassembly and maintenance and reducing the damage probability of the plunger pump.

In some examples, the plunger pump device500described above can be a fracturing truck. Of course, the embodiments of the present disclosure include but are not limited thereto, and the above-mentioned plunger pump device can also be other devices including plunger pumps.

In some examples, as illustrated inFIG.9, the plunger pump200is respectively fixed with the support assembly110and the extension block128. Therefore, plunger pumps of different sizes can be supported and fixed by adjusting the position of the extension block, and stable support can be provided for the plunger pump.

For example, the support assembly110is configured to bear and fix the power end210and the hydraulic end220of the plunger pump200. The extension block128is configured to bear and fix the gear box230of the plunger pump200. It should be noted that, usually, the weight of the power end of the plunger pump is relatively large, while the weight of the gear box is relatively light, so the plunger pump can be made more stable in working state through the above arrangement.
