Technical scheme: The adjustable intermediate disk body of large double-layer cage in the present invention comprises cage columns, a main intermediate disk body arranged in the cage columns, and a chain block and a connecting piece connected to a cage suspension board, wherein, an intermediate disk guide rail beam for the main intermediate disk body to move up and down is arranged on the inner side of the cage columns, wedge bases designed to fix the descending position of the main intermediate disk body are arranged symmetrically on the two sides of the lower part of the intermediate disk guide rail beam, a limited block is arranged on the upper part of the intermediate disk guide rail beam, a bolt hole designed to fix the ascending position of the main intermediate disk body is arranged in the limited block; intermediate disk wedge bodies, which match the wedge faces of the wedge bases, are arranged on the two side faces of the main intermediate disk body, at positions corresponding to the intermediate disk guide rail beam, an intermediate disk guide wheel that is fitted with the intermediate disk guide rail beam and an intermediate disk guide wheel seat with a bolt hole are arranged on the upper part of the intermediate disk wedge body; an anti-disengaging plate is arranged on the intermediate disk guide rail beam.
An adjusting and moving method for the adjustable intermediate disk body of large double-layer cage described above, comprising:
After the large double-layer cage is docked at a level for transporting equipment into the cage, connecting the main intermediate disk body via the chain block and connecting piece, applying force in the forward direction to lift up the main intermediate disk body from the wedge bases and driving the main intermediate disk body to move upwards, and then the bolts are inserted into the bolt holes when the bolt holes of the intermediate disk guide wheel seats are aligned to the bolt holes of the limited blocks on the cage columns, to fix the main intermediate disk body at the level of the limited blocks;
After the large double-layer cage is docked at a level for transporting equipment out of the cage, connecting the main intermediate disk body via the chain block and connecting piece, applying force in the forward direction to release the load on the bolts, and then pulling out the bolts and applying force in the reversed direction, to lower the main intermediate disk body onto the wedge bases.
Beneficial effects: With the technical scheme described above, by arranging guide rails on the cage columns, the fixed intermediate disk body can be moved up and down along the guide rails, so that the space in the double-layer cage can be changed, the height of the cage can be adjusted according to the large-size equipment to be transported, so as to utilize the vertical space in a large double-layer cage and meet the requirement for integral transport of large-size equipment (e.g., a large-size hydraulic support) into the down-hole area. The adjustable intermediate disk body of large double-layer cage is compact in structure, easy to move and adjust, and has high practicability.

DETAILED DESCRIPTION OF THE EMBODIMENTS
Hereunder the present invention will be further detailed in an embodiment, with reference to the accompanying drawings:
As shown in FIG. 1, the adjustable intermediate disk body of large double-layer cage provided in the present invention mainly consists of cage columns 1, a main intermediate disk body 2 arranged in the cage columns 1, and a chain block and a connecting piece 4 connected to a cage suspension board 5, wherein, the main intermediate disk body 2 is made of profile steels and steel plates by welding.
As shown in FIG. 2, an intermediate disk guide rail beam 1-1 for the main intermediate disk body 2 to move up and down is arranged on the inner side of the cage columns 1, wedge bases 1-2 designed to fix the descending position of the main intermediate disk body 2 are arranged symmetrically on the two sides of the lower part of the intermediate disk guide rail beam 1-1, a limited block 1-4 is arranged on the upper part of the intermediate disk guide rail beam 1-1, a bolt hole designed to fix the ascending position of the main intermediate disk body 2 is arranged in the limited block 1-4, and an anti-disengaging plate 1-3 is arranged on the intermediate disk guide rail beam 1-1.
As shown in FIG. 3 and FIG. 4, intermediate disk wedge bodies 2-1 that match the wedge faces of the wedged bases 1-2 are arranged on the two side faces of the main intermediate disk body 2, at positions corresponding to the intermediate disk guide rail beams 1-1; an intermediate disk guide wheel 2-2 that is fitted with the intermediate disk guide rail beam 1-1 and an intermediate disk guide wheel seat 2-3 with a bolt hole are arranged on the upper part of the intermediate disk wedged body 2-1; the intermediate disk wedge body 2-1 and intermediate disk guide wheel seat 2-3 can be fixed to the main intermediate disk body 2 with high strength bolts.
An adjusting and moving method for the adjustable intermediate disk body of large double-layer cage described above, as follows:
As shown in FIG. 5, after the large double-layer cage is docked at a level for transporting equipment into the cage, the chain block and connecting piece 4 are connected to the main intermediate disk body 2 before the large-size equipment is loaded into the case, then, force is applied in the forward direction via the chain block and connecting piece 4 connected to a cage suspension board 5 to lift up the main intermediate disk body 2 from the wedge bases 1-2 and drive the main intermediate disk body 2 to move upwards, and then the bolts 3 are inserted into the bolt holes when the bolt holes of the intermediate disk guide wheel seats 2-3 are aligned to the bolt holes of the limited blocks 1-4 on the cage columns 1, to fix the main intermediate disk body 2 at the level of the limited blocks;
After the large double-layer cage is docked at a level for transporting equipment out of the cage, chain block and connecting piece 4 are connected to the main intermediate disk body 2 after the equipment is transported out of the cage, then, force is applied in the forward direction via the chain block and connecting piece 4 connected to a cage suspension board 5 to release the load on the bolts 3, and then the bolts are pulled out and force is applied in the reversed direction, to lower the main intermediate disk body 2 onto the wedge bases 1-2. In addition, the upper-layer door of the cage is of rolling shutter type or removable, and the side walls near the main intermediate disk body 2 is movable with the main intermediate disk body 2, to avoid interfering with the adjustment and movement of the main intermediate disk body 2.
