Description
Technical Field
[0001] The utility model relates to the technical field of mining, in particular to a self-returning, efficient and safe mining car cleaning machine. Background Art
[0002] Mine cars are narrow-gauge railway transport vehicles used to transport bulk materials such as coal, ore and waste rock in mines. They are generally towed by locomotives or winches. Mine cars are divided into five categories according to their structure and unloading methods: fixed mine cars (material cars, flatbed cars), dump mine cars, single-sided curved track side-unloading mine cars, bottom (side) unloading mine cars and shuttle mine cars. A vehicle pulled by a locomotive or winch to transport coal, gangue, equipment, facilities and personnel. Mine cars are mainly used for rail transportation in underground mine tunnels, shafts and on the ground. They are the largest and most widely used type of transportation equipment in coal mines.
[0003] In the prior art, after the mine car is tilted, residual debris and slag often adhere to the inner wall of the mine car, which is not easy to remove. The common method is to pry the mine car with a hammer or a crowbar, but this method is inefficient. After actual investigation of the mine, this invention is specially applied for to solve this technical problem. Utility Model Content
[0004] In order to solve the above-mentioned problems in the prior art, the utility model provides a self-returning, efficient and safe mining car cleaning machine, which can improve the above-mentioned deficiencies.
[0005] The utility model relates to a self-returning efficient and safe mining car cleaning machine, comprising a lower bracket, an upper bracket, a cylinder, a crossbeam and a pneumatic hammer mechanism, wherein the upper bracket is arranged above the lower bracket, a cylinder is arranged in the upper bracket, a Y joint is arranged at the front section of the piston rod of the cylinder, one end of the crossbeam is rotatably connected with the Y joint through an I joint, a bearing seat is arranged near the position of the I joint of the crossbeam, the crossbeam is rotatably connected with the bearing seat through a shaft rod, and the pneumatic hammer mechanism is arranged at the other end of the crossbeam. The crossbeam is tilted upward when the cylinder is not started.
[0006] Furthermore, a foot valve is arranged on the outer side of the lower bracket, and the foot valve controls the cylinder.
[0007] Furthermore, the pneumatic hammer mechanism includes a door-type frame and two pneumatic hammer cylinders arranged at the lower end of the door-type frame, and pneumatic hammers are arranged in the pneumatic hammer cylinders.
[0008] Furthermore, a nitrogen cylinder is arranged at the front side of the upper bracket below the cross beam, and a cam follower is arranged at the driving end of the nitrogen cylinder, and the cam follower contacts the cross beam.
[0009] Furthermore, a mechanical valve is arranged near the top surface of the upper bracket on the crossbeam, and the mechanical valve controls the start-up of the air hammer.
[0010] Furthermore, a compressor is arranged in the lower bracket, and the compressor is connected to the cylinder and the air hammer barrel respectively through pipelines.
[0011] The utility model has a novel structure. The improvement of this scheme lies in that the crossbeam is in an upward tilted state when it is not accepted. The crossbeam is driven by the air cylinder, and the front end of the crossbeam rotates downward, and at the same time the mechanical valve is touched. The mechanical fee starts the air hammer to hammer, and then the foot valve is released, the air cylinder is pulled back, and at the same time the nitrogen cylinder rises, and the crossbeam is tilted upward to recover. The feature of this design is that the nitrogen cylinder is designed, so that the equipment can be restored without the use of external force. BRIEF DESCRIPTION OF THE DRAWINGS
