Description

Technical Field

[0001] This utility model relates to the field of mining car technology, specifically to a mining car that facilitates unloading. Background Technology

[0002] Mining cars are special vehicles for rail transport in mines. To adapt to the narrow conditions of underground roadways, they are compact in size and include freight cars, personnel cars, and material cars. Mining cars are narrow-gauge railway transport vehicles used in mines to transport bulk materials such as coal, ore, and waste rock. They are generally pulled by locomotives or winches.

[0003] However, existing tipper mine cars require manual opening of the limit switch of the car bucket during unloading, which is physically demanding for workers and can easily cause injury if not operated properly, resulting in poor performance. Therefore, providing a mine car that facilitates tipping of the car bucket is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a mine car that is easy to unload, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mine car for easy unloading, comprising:

[0006] The frame has a cargo box rotatably connected to its top and wheels rotatably connected to its bottom, which are in contact with the rails.

[0007] There is a pair of rotating shafts, which are fixedly installed on the two end faces of the truck bed, with the rotating shafts located on one side of the vertical center line of the truck bed;

[0008] End plates, in pairs, are fixedly installed at both ends of the upper surface of the frame, and the shaft is rotatably connected to the end plates;

[0009] The tipping switch assembly is set on the end plate in the direction of the mine car's forward movement. It includes a rotating rod that is rotatably mounted on the upper part of the end plate. A stop bar is fixedly installed above one end of the rotating rod. A stop block corresponding to the stop bar is fixedly installed on the car bucket. When the stop bar blocks the stop block, the car bucket is in a vertical state. When the rotating rod is rotated, the stop bar can be moved out from in front of the stop block. Due to the shift in the center of gravity of the car bucket, it can tip over to one side.

[0010] Preferably, a lever is fixedly installed below the other end of the rotating rod, and a torsion spring is installed on the rotating rod, which can push the stop bar to move to one side of the stop block.

[0011] Preferably, a push rod is fixedly installed on one side of the rail, and the movement of the mine car can cause the lever to contact the push rod, thereby causing the rotating rod to rotate.

[0012] Preferably, a limiting block 1 and a limiting block 2 are fixedly provided on the end face of the truck bed away from the stop block. When the truck bed is overturned, the limiting block 1 can contact the end plate, and when the truck bed is in a vertical state, the limiting block 2 can contact the end plate.

[0013] Preferably, a handle is fixedly provided on the limiting block.

[0014] Preferably, the stop is triangular, which can push the stop lever outward during the process of pushing the truck bed to move into a vertical position.

[0015] Beneficial effects

[0016] This utility model provides a mine car that facilitates unloading, with the following advantages: the mine car can move forward to make the lever contact with the push rod set at the unloading point. The push rod can push the lever to make the bucket unrestrained. By setting the rotating shaft on one side of the vertical center line of the bucket, a center of gravity shift effect is created. Under its own weight, it can be flipped to one side to dump the material inside the bucket. There is no need to design a complex mechanical structure, which reduces the manufacturing cost of the mine car. The simple structure reduces maintenance costs. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figures 1-5 This utility model provides a technical solution: a mine car that facilitates unloading, comprising:

[0025] The frame 1 has a rotatable bucket 2 for holding materials connected to its upper part, and a wheel 5 that contacts the rail 6 connected to its lower part.

[0026] A pair of rotating shafts 3 are fixedly installed on the two ends of the truck bed 2. The rotating shafts 3 are located on one side of the vertical center line of the truck bed 2, creating a center of gravity shift effect. When the truck bed 2 is not restricted, it can flip to one side by its own weight.

[0027] End plates 4, in pairs, are fixedly installed at both ends of the upper surface of the frame 1, and the rotating shaft 3 is rotatably connected to the end plates 4;

[0028] The tipping switch assembly, used to limit the tipping of the car bucket 2, is set on the end plate 4 in the forward direction of the mine car. It includes a rotating rod 7 rotatably mounted on the upper end of the end plate 4. A stop bar 8 is fixedly installed above one end of the rotating rod 7. A stop block 9 corresponding to the stop bar 8 is fixedly installed on the car bucket 2. When the stop bar 8 blocks the stop block 9, the car bucket 2 is in a vertical state. When the rotating rod 7 rotates, the stop bar 8 can be moved out from in front of the stop block 9. Due to the shift of the center of gravity of the car bucket 2, it can tip over to one side, thereby dumping out the material inside.

[0029] As an embodiment of this utility model, a lever 10 is fixedly provided below the other end of the rotating rod 7, and a torsion spring 12 is installed on the rotating rod 7. The torsion spring 12 can push the stop rod 8 to move towards the stop block 9.

[0030] As an embodiment of this utility model, a push rod 11 is fixedly installed on one side of the rail 6. The push rod 11 is located at the unloading point. When the mine car moves, the lever 10 can contact the push rod 11, thereby causing the rotating rod 7 to rotate, so that the car bucket 2 can be automatically overturned when the mine car moves to the unloading point.

[0031] As an embodiment of this utility model, a first limiting block 13 and a second limiting block 14 are fixedly provided on the end face of the truck bed 2 away from the stop block 9. When the truck bed 2 is flipped, the first limiting block 13 can contact the end plate 4. When the truck bed 2 is in a vertical state, the second limiting block 14 can contact the end plate 4, thereby limiting the flipping of the truck bed 2.

[0032] As an embodiment of this utility model, a handle 15 is fixedly provided on the limiting block 13 to facilitate pushing the cart 2 from the flipped state to the vertical state.

[0033] As one embodiment of this utility model, the stop block 9 is triangular and can push the stop lever 8 outward during the process of pushing the truck bed 2 to move in a vertical state.

[0034] The working principle and usage process of this utility model are as follows: When the mine car moves to the unloading point, the forward movement of the mine car causes the lever 10 to contact the push rod 11 located at the unloading point. The push rod 11 pushes the bottom of the lever 10 to rotate the rotating rod 7. The rotation of the rotating rod 7 causes the stop rod 8 to move out from in front of the stop block 9. At this time, the car bucket 2 is unrestrained. Since the rotating shaft 3 is located on one side of the vertical center line of the car bucket 2, it creates a center of gravity shift effect. Under its own weight, it can flip to one side, dumping the material inside the car bucket 2. After the material is dumped, the worker can pull the handle 15 to push the car bucket 2 to a vertical position. When the car bucket 2 moves, the triangular stop block 9 contacts the stop rod 8, which can push the stop rod 8 outward. When the stop block 9 moves to the rear of the stop rod 8, the torsion spring 12 can push the stop rod 8 to move towards the stop block 9, so that the stop rod 8 moves to the front of the stop block 9, thereby limiting the car bucket 2 and preventing the car bucket 2 from flipping.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
