Description

Technical Field

[0001] The utility model relates to the technical field of mine cars, and more specifically to a U-shaped mine car ore dumping device. Background Art

[0002] A mine car is a narrow-gauge railway transport vehicle used to transport bulk materials such as coal, ore and waste rock in mines. It is generally towed by a locomotive or winch. Mine cars are divided into five categories according to their structure and unloading methods: fixed mine cars, tipping mine cars, single-sided curved track side-unloading mine cars, bottom-unloading mine cars and shuttle mine cars. Among them, the tipping mine car has a V-shaped or U-shaped car body, which is supported on the turning rails of the frame, and the car body is turned over on the turning rails for unloading.

[0003] After searching, the utility model patent with announcement number CN213168059U discloses a mechanized ore dumping device for U-shaped mine cars, in which a winch is installed on the opposite side of the original ore bin, fixed pulleys are installed on the rail steel shed bracket, and a tipping hook seat is welded on the right side plate of the U-shaped mine car. The end of the forward wire rope of the winch passes through the fixed pulley and the two hooks at the end of the reverse wire rope can be connected together. After the electric locomotive stops, the operator buckles the hook on the hook seat of the mine car; when the winch is started to rotate forward, the U-shaped mine car turns sideways to the original ore bin to dump the ore, the winch is reversed, and after the mine car is reset, the operator separates the hook from the hook seat to complete a mine dumping; this patent only requires one person to operate the winch and the hook to complete the mechanized mine dumping, which can reduce labor intensity, save manpower, save costs, and improve production efficiency; at the same time, it improves the personal safety of workers and effectively avoids the occurrence of industrial accidents; and the mine car does not need to be accurately positioned and parked, as long as it stops within the range of a mine car, the mine dumping can be completed.

[0004] However, the above patents still have the following shortcomings: workers need to connect and disconnect the hook and the hook seat when unloading the ore, which is not convenient; in addition, the ore can only be unloaded at the position with a winch on the side, which is not practical. For this reason, we propose a U-shaped mine car unloading device. Utility Model Content

[0005] In view of the problems existing in the prior art, the utility model aims to provide a U-shaped mine car ore dumping device.

[0006] In order to solve the above problems, the utility model adopts the following technical solutions:

[0007] A U-shaped mine car unloading device comprises a seat, the top of the seat is fixedly connected to two support frames, a U-shaped mine bucket is rotatably connected between the two support frames, one end of the two rotating shafts of the U-shaped mine bucket respectively extends to the outside of the two support frames and is fixedly sleeved with spur gears, the outside of the support frame is fixedly connected to a mounting seat, a first electric push rod is fixedly installed on the mounting seat, the output end of the first electric push rod is fixedly connected to a rack, the rack and the spur gear are meshed with each other, fixing holes are respectively opened on both sides of the U-shaped mine bucket, and fixing mechanisms are provided on the two support frames.

[0008] As a preferred solution of the utility model, the fixing mechanism includes a second electric push rod fixedly mounted on the outside of the support frame, the output end of the second electric push rod is fixedly connected to a fixing pin, and the end of the fixing pin passes through the support frame and extends to the inner cavity of the fixing hole.

[0009] As a preferred solution of the utility model, a second connecting seat is provided at one end of the vehicle seat, and a first connecting seat is provided at the other end of the vehicle seat.

[0010] As a preferred solution of the utility model, a storage battery is arranged inside the vehicle seat, and track wheels are rotatably connected to both sides of the vehicle seat.

[0011] As a preferred solution of the utility model, a protection box is fixedly connected to the outer side of the support frame, and a controller is fixedly installed on the outer side of the protection box.

[0012] As a preferred solution of the utility model, the inner wall of the fixing hole and the side surface of the fixing pin are in contact with each other.

[0013] Compared with the prior art, the advantages of the present invention are:

[0014] (1) In the utility model, the U-shaped ore bucket is supported by a support frame. When the material needs to be dumped, the first electric push rod is used to drive the rack to move upward, and the meshing transmission between the rack and the spur gear is used to drive the spur gear and the U-shaped ore bucket to rotate, so that the ore in the U-shaped ore bucket can be dumped out, ensuring that the mine car can dump the ore by itself.

[0015] (2) In the utility model, by using the fixing hole, the second electric push rod and the fixing pin in coordination, when the U-shaped ore bucket is used to load ore materials, the fixing pin is inserted into the fixing hole by the second electric push rod to fix the U-shaped ore bucket, thereby ensuring the supporting strength of the U-shaped ore bucket and limiting the position of the U-shaped ore bucket, thereby improving the working quality of the U-shaped mine car unloading device.
