Title: Stepping-Type Propulsion Means for Excavators
IPC: E02F9/04
Filed: 1966-11-01
Abstract: 1,154,523. Walking machines. RUSTONBUCYRUS Ltd. 1 Nov., 1966 [3 Nov., 1965], No. 48886/66. Heading B7H. In a walking machine, i.e. a drag-line excavator, having a frame 1, the propulsion means comprise shoes 12, one on either side of the machine, and associated with each shoe a vertical hydraulic ram 14 mounted on the frame; a slide 20; a ball and socket jointed 16-18 between the slide and the shoe; a slideway on the shoe to receive the slide, and a horizontal ram 23 to effect horizontal movement of the shoe with respect to the frame. Rollers 32, 34, mounted on brackets 30, 33 extending from the frame, level and align the shoe during walking. A pair of ropes 40 attached between the shoe and a sheave 36 via sheave blocks 39 keep the shoe parallel to the frame since the sheave 36 is prevented from rotating by a constant pressure ram 37. The guides 22 are made to converge from left to right to centre the shoe as it moves to the left. The shoes are controlled by an hydraulic circuit, Fig. 11, in the manner hereinafter described starting from the condition wherein the shoes are raised from the ground and the machine is supported by a tub 2. For the machine to take a step the shoes are lowered to the ground by energizing induction motors M 1 -M 5  thereby operating pumps P 1 - P 10  to pump fluid into the top of ram 14 through line 43, the valves 44, 46, 48 and 56 being open. As soon as the piston 15 begins to move the shoe's weight is the major force acting and fluid is moved from the lower end of ram 14 into the pumps, via line 45, thereby driving them and causing the motors to generate electricity. Extra fluid required in the top end of ram 14 is supplied from a reservoir through valve 48. This valve is closed by a pressure switch 49 which senses the zero perssure in ram 14 when the shoe touches the ground. Raising the machine involves further extension of ram 14. Line 45 is connected to the reservoir through valve 42 and fluid pumped into the top of the ram until the machine is raised, this condition being sensed by pressure switch 50. The valves 44, 46 and 56 are then closed and the pumps stopped. The machine can then be propelled forward by extending ram 23. This is accomplished by reversing the direction of pumping and supplying fluid through line 59. The machine may then be lowered by pumping into the lower end of ram 14, but almost immediately the weight of the machine becomes the major force, causing the motors to act again as generators. When the machine is grounded pumps P 1 -P 4  pump into the lower end of ram 14 to raise the shoe and pumps P 5 -P 10  pump into the right-hand end of ram 23 to slide the shoe to its initial position. A walking step has now been completed.
