Description

Technical Field

[0001] This utility model relates to the field of mine car tipping technology, and specifically discloses an automatic mine car tipping device. Background Technology

[0002] In underground mining operations, 1m³ stationary mining cars are widely used as standardized loading containers. After the ore is loaded and transported to the designated location, efficient and safe unloading is a key aspect of ensuring production efficiency.

[0003] Currently, in many mining sites, the traditional manual unloading method is still widely used to unload mine cars. This method usually requires multiple workers to work together, using tools such as shovels, or directly pushing or prying the heavily loaded mine cars to tip them over. This process is not only inefficient, resulting in slow vehicle turnover, but also poses significant safety hazards such as mine car tipping and cargo slippage because operators have to be in close proximity to unstable loads. At the same time, the high-intensity physical labor also places a considerable burden on the physical and mental health of the workers.

[0004] Therefore, an automatic mine car tipping device is needed to solve the above problems. Utility Model Content

[0005] This utility model proposes an automatic mine car tipping device, which automatically controls the tipping frame movement through a drive mechanism to realize the mechanized tipping of the mine car, replacing the manual tipping operation of multiple people, significantly improving unloading efficiency and mine car turnover speed, while reducing labor intensity and safety hazards caused by direct manual operation.

[0006] This utility model is implemented as follows: an automatic tipping device for mine cars includes a fixed frame and a tipping frame, and a drive mechanism and a counterweight mechanism are provided on the outer side of the tipping frame. The drive mechanism includes a mounting frame fixedly connected to the left end of the fixed frame. A reducer and a cross plate are fixedly connected to the left end of the mounting frame. A motor with its output end fixedly connected to the input end of the reducer is mounted on the upper end of the cross plate. The output end of the reducer passes through the mounting frame and is fixedly connected to a small gear. A rotating shaft is rotatably connected to the outer wall of the mounting frame. A large gear meshing with the small gear is fixedly connected to the outer wall of the rotating shaft. Two drums are arranged above the tippler frame. The drum on the left is fixedly connected to the right end of the rotating shaft. Two first guide wheels are rotatably connected to the outer wall of the fixed frame. A first traction steel rope is fixedly wound on the outer wall of both drums. The other ends of the two first traction steel ropes are fixedly connected to the front end of the tippler frame. The two first traction steel ropes abut against the grooves of the two first guide wheels respectively.

[0007] As a preferred embodiment of the automatic tipping device for mine cars according to this utility model, the counterweight mechanism includes a second guide wheel rotatably connected to the front end of the fixed frame, a movable pulley provided to the right of the second guide wheel, a second traction steel rope fixedly connected to the front end of the tipping frame and abutting against the groove of the second guide wheel and the movable pulley, the other end of the second traction steel rope being fixedly connected to the fixed frame, a vertical plate provided to the right of the fixed frame, a counterweight block provided in front of the vertical plate, and a third traction steel rope fixedly connected between the counterweight block and the movable pulley.

[0008] As a preferred embodiment of the automatic tipping device for mine cars according to this utility model, the front end of the vertical plate is rotatably connected to three third guide wheels, and the third traction steel ropes all abut against the grooves of the three third guide wheels.

[0009] As a preferred embodiment of the automatic tipping device for mine cars according to this utility model, the outer wall of the fixed frame is rotatably connected to two movable sleeves, the lower ends of the two movable sleeves are fixedly connected to fixed seats, and the two fixed seats are fixedly connected to the tipping frame.

[0010] As a preferred embodiment of the automatic tipping device for mine cars of this utility model, a connecting shaft is fixedly connected between the two drums, passing through the fixing frame and rotatably connected to the fixing frame.

[0011] As a preferred embodiment of the automatic tipping device for mine cars according to this utility model, a control distribution box is installed at the front end of the vertical plate.

[0012] The beneficial effects of this utility model are: Driven by an electric motor, a worm gear reducer rotates synchronously via the meshing of a pinion and a large gear, winding up the first traction steel rope. This rope is then guided by the first guide wheel and tilts the tipper upwards. Simultaneously, the tipper, via a second traction steel rope, moves a movable pulley, causing the counterweight to descend and balance the load. During unloading, the electric motor reverses, the drum releases the first traction steel rope, and the tipper, under its own weight, rotates downwards to the unloading angle to complete the unloading, while the counterweight rises. This entire process achieves automated mechanical tipping of the mine car, effectively replacing traditional manual unloading operations requiring multiple personnel, significantly improving unloading efficiency and mine car turnaround speed, while reducing labor intensity and operational safety hazards.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0017] Please see Figure 1-3 An automatic tipping device for mine cars includes a fixed frame 1 and a tipping frame 4, with a drive mechanism and a counterweight mechanism provided on the outer side of the tipping frame 4. The drive mechanism includes a mounting frame 5 fixedly connected to the left end of the fixed frame 1. A reducer 6 and a cross plate 12 are fixedly connected to the left end of the mounting frame 5. A motor 7 with its output end fixedly connected to the input end of the reducer 6 is mounted on the upper end of the cross plate 12. The output end of the reducer 6 passes through the mounting frame 5 and is fixedly connected to a pinion 8. A rotating shaft 10 is rotatably connected to the outer wall of the mounting frame 5. A large gear 9 that meshes with the pinion 8 is fixedly connected to the outer wall of the rotating shaft 10. Two drums 11 are arranged above the tippler frame 4. The drum 11 on the left is fixedly connected to the right end of the rotating shaft 10. Two first guide wheels 14 are rotatably connected to the outer wall of the fixed frame 1. A first traction steel rope 17 is fixedly wound on the outer wall of both drums 11. The other ends of the two first traction steel ropes 17 are fixedly connected to the front end of the tippler frame 4. The two first traction steel ropes 17 respectively abut against the grooves of the two first guide wheels 14.

[0018] In this embodiment: the motor 7 is started, and the output shaft of the motor 7 drives the worm gear reducer 6 to operate. The reducer 6 transmits power to the pinion 8 connected to its output end, and the pinion 8 drives the large gear 9 meshing with it to rotate. The large gear 9 is fixedly mounted on the rotating shaft 10, thereby driving the rotating shaft 10 to rotate synchronously, and at the same time, the two drums 11 rotate synchronously.

[0019] As the drum 11 rotates, the first traction steel rope 17 wound around its outer wall is wound up. After being guided by the first guide wheel 14 installed on the outer wall of the fixed frame 1, the first traction steel rope 17 is connected to the front end of the tippler frame 4. As the first traction steel rope 17 tightens, the tippler frame 4 rotates and rises upward.

[0020] As the tippler 4 rises, the counterweight mechanism operates synchronously. The second traction steel rope 20, connected to the front end of the tippler 4, passes over the second guide wheel 18 and the movable pulley 19, with its other end fixed to the fixed frame 1. When the tippler 4 rises, the horizontal section of the second traction steel rope 20 lengthens, pulling the movable pulley 19 to the right under the traction of the counterweight block 16 and the third traction steel rope 22, causing the counterweight block 16 to descend. This counterweight mechanism effectively balances the load on the tippler 4 and the mine car, reducing the load on the motor 7.

[0021] When it is time to unload the ore, the output shaft of the motor 7 rotates in the opposite direction, which in turn drives the two drums 11 to rotate in the opposite direction, unwinding the two first traction steel ropes 17. The tipper frame 4 rotates downward. When the tipper frame 4 rotates to the predetermined unloading angle, the ore in the mine car is unloaded under the action of gravity. At the same time, it causes the movable pulley 19 to move to the left, causing the counterweight block 16 to rise.

[0022] The entire process is automated and mechanized, replacing the traditional manual unloading method that requires multiple people to work together. This significantly improves unloading efficiency and mine car turnover speed, while reducing labor intensity and operational safety hazards.

[0023] As a technical optimization of this utility model, the counterweight mechanism includes a second guide wheel 18 rotatably connected to the front end of the fixed frame 1, a movable pulley 19 provided to the right of the second guide wheel 18, a second traction steel rope 20 fixedly connected to the front end of the tipper frame 4 and abutting against the groove of the second guide wheel 18 and the movable pulley 19, the other end of the second traction steel rope 20 being fixedly connected to the fixed frame 1, a vertical plate 21 provided to the right of the fixed frame 1, a counterweight block 16 provided in front of the vertical plate 21, and a third traction steel rope 22 fixedly connected between the counterweight block 16 and the movable pulley 19.

[0024] In this embodiment: the second traction steel rope 20 connected to the front end of the tippler 4 passes around the second guide wheel 18 and the movable pulley 19, and the other end is fixed to the fixed frame 1. Under the traction of the counterweight block 16 and the third traction steel rope 22, the tippler 4 applies a pulling force to the movable pulley 19 and the tippler 4. This counterweight mechanism effectively balances the load of the tippler 4 and the mine car, and reduces the load of the motor 7.

[0025] As a technical optimization of this utility model, the front end of the upright plate 21 is rotatably connected to three third guide wheels 23, and the third traction steel rope 22 abuts against the grooves of the three third guide wheels 23.

[0026] In this embodiment, when the third traction steel rope 22 connects the movable pulley 19 and the counterweight 16, it fits tightly in the grooves of the three third guide wheels 23, ensuring that the third traction steel rope 22 always moves along the predetermined trajectory during the transmission process.

[0027] As a technical optimization of this utility model, the outer wall of the fixed frame 1 is rotatably connected to two movable sleeves 2, and the lower ends of the two movable sleeves 2 are fixedly connected to fixed seats 3, and the two fixed seats 3 are fixedly connected to the tipper frame 4.

[0028] In this embodiment, the movable sleeve 2 is rotatably connected to the outer wall of the fixed frame 1, and the fixed seat 3 at its lower end is rigidly connected to the tipper frame 4. This structure provides a rotation fulcrum for the tipper frame 4.

[0029] As a technical optimization of this utility model, a connecting shaft 13 is fixedly connected between the two drums 11, passing through the fixing frame 1 and rotatably connected to the fixing frame 1.

[0030] In this embodiment, the connecting shaft 13 is fixedly connected between the two drums 11 and passes through the fixing frame 1 to form a rotatable connection with them. The connecting shaft 13 can ensure that the two drums 11 rotate absolutely synchronously, thereby ensuring that the first traction steel rope 17 on both sides has the same winding and unwinding speed.

[0031] As a technical optimization of this utility model, a control distribution box 15 is installed at the front end of the upright plate 21.

[0032] In this embodiment, the operator can easily control the forward and reverse rotation, start and stop of the motor 7 by controlling the buttons on the distribution box 15.

[0033] The working principle and usage process of this utility model are as follows: The operator starts the motor 7 by controlling the distribution box 15. The output shaft of the motor 7 drives the worm gear reducer 6 to rotate. The reducer 6 transmits power to the pinion 8 connected to its output end, and the pinion 8 drives the large gear 9 meshing with it to rotate. The large gear 9 is fixedly installed on the rotating shaft 10, thereby driving the rotating shaft 10 to rotate synchronously. The right end of the rotating shaft 10 is fixedly connected to the left drum 11, and the two drums 11 are fixed together by the connecting shaft 13 to achieve synchronous rotation of the two drums 11.

[0034] As the drum 11 rotates, the first traction steel rope 17 wound around its outer wall is wound up. After being guided by the first guide wheel 14 installed on the outer wall of the fixed frame 1, the first traction steel rope 17 is connected to the front end of the tippler frame 4. As the first traction steel rope 17 tightens, the tippler frame 4 rotates and rises upward around the hinge point between the movable sleeve 2 and the fixed frame 1 under the action of tension.

[0035] As the tippler 4 rises, the counterweight mechanism operates synchronously. The second traction steel rope 20, connected to the front end of the tippler 4, passes over the second guide wheel 18 and the movable pulley 19, with its other end fixed to the fixed frame 1. When the tippler 4 rises, the horizontal section of the second traction steel rope 20 lengthens, pulling the movable pulley 19 to the right under the traction of the counterweight block 16 and the third traction steel rope 22, causing the counterweight block 16 to descend. This counterweight mechanism effectively balances the load on the tippler 4 and the mine car, reducing the load on the motor 7.

[0036] When it is necessary to unload the ore, the output shaft of the motor 7 rotates in the opposite direction, which in turn drives the two drums 11 to rotate in the opposite direction, unwinding the two first traction steel ropes 17. The tipper frame 4 rotates downward around the hinge point between the movable sleeve 2 and the fixed frame 1. When the tipper frame 4 rotates to the predetermined unloading angle, the ore in the mine car is unloaded under the action of gravity. At the same time, it causes the movable pulley 19 to move to the left, causing the counterweight 16 to rise.

[0037] The entire process is automated and mechanized, replacing the traditional manual unloading method that requires multiple people to work together. This significantly improves unloading efficiency and mine car turnover speed, while reducing labor intensity and operational safety hazards.
