Embodiment 1

[0050] The method of walking by self-moving tail is as follows:

[0051] ①. All parts of the fuselage are in a quasi-working state;

[0052] ②. The front part is connected with the belt conveyor, and the rear part is connected with the transfer conveyor;

[0053] ③. Open the hydraulic mechanism, input hydraulic oil to the forward, middle, rear, left and right lift cylinders at the same time, the piston rod of each lift cylinder extends outwards, and supports upwards simultaneously, and the fuselage and the bottom shoes are lifted up in parallel with the ground as a whole. 220mm; the left and right guide rails are load-bearing on the ground and become the thrust fulcrum of the left and right walking cylinders;

[0054] ④. Open the hydraulic mechanism, inject hydraulic oil into the left and right travel cylinders at the same time, the piston rods of the left and right travel cylinders extend out synchronously, take the left and right guide rails as the fulcrum, push the fuselag...

Abstract

The invention relates to a walking running device for a self-advancing tail, which mainly comprises a body, running oil cylinders, lifting oil cylinders, oil cylinder holders, a roller frame, guide rails, a floating carrier roller, a movable trolley base and a hydraulic mechanism. Aiming at the actual situation that the self-advancing tail is 20 meters long, 1.5 meters high and 40 tons heavy and is difficult to move, traction movement is changed into walking running movement, a high-power hydraulic power is adopted, the lifting oil cylinders are symmetrically arranged on the left, right, front, middle and rear of the body, the guide rails and the running oil cylinders are arranged on left and right sides of the body; and when the body is lifted, the guide rails are pulled and pushed by the running oil cylinders synchronously to slide forwards, so that the function of walking and running synchronously is realized, wherein the lifting height of the body is 220 millimeters, the displacement at each stroke is 1,200 millimeters, and the power of the lifting oil cylinders and the running oil cylinders is 31.5 MPa. The self-advancing tail can move forwards in a left-to-right or right-to-left manner, and the walking running device is advanced in design, reasonable in arrangement, convenient for operation, safe, stable and reliable.

Description

technical field [0001] The invention relates to a walking device for self-moving tail, which belongs to the technical field of supporting devices for underground transportation equipment in coal mines. Background technique [0002] With the development of coal mining technology, various types and functions of self-moving tails of belt conveyors are widely used in fully mechanized mining face in coal mines. The intermediate connection equipment of the machine is suitable for high-yield and high-efficiency working faces, which can not only ensure the smooth connection between the trough transfer machine and the belt conveyor, but also meet the requirements of rapid advancement of the working face. [0003] At present, the 10-million-ton modern mine has good geological conditions, large coal storage, and smooth coal seam, which can carry out high-power and high-efficiency modern coal mining operations. The advancing speed is fast, so the slot transfer machine and the belt conv...
