Abstract
Description
Technical Field
[0001] This utility model relates to the field of mining transportation equipment technology, and in particular to a traction device for automatic loading of mine cars into mine containers. Background Technology
[0002] In mining operations, after mine cars transport ore to the shaft entrance, they need to be pulled into a cage to lift the ore to the surface. Traditional methods of loading mine cars into cages mostly rely on manual traction or simple mechanical traction devices, which suffer from low efficiency and poor safety. Manual traction requires a large amount of manpower and is prone to personnel injury during operation; while existing mechanical traction devices are not precise enough in positioning the mine cars during traction, and are prone to detaching from the mine cars, causing loading failure. Therefore, this paper presents a traction device for automatic loading of mine cars into cages. Utility Model Content
[0003] In view of the shortcomings of the prior art, this utility model provides a traction device for automatic loading of mine cars into the mine car, which does not require manual traction, and is accurately positioned during the traction process, making it less likely to fall off the mine car, thus solving the problem of poor efficiency and overcoming the shortcomings of the prior art.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A traction device for automatic loading of mine cars into a mine car includes rails and a mine car. A fixed frame is provided between two rails. Two rotating rods are rotatably mounted on both ends of the inner wall of the fixed frame via bearings. A sprocket is fixed to both ends of the two rotating rods. A chain is connected between the two sprockets of the two rotating rods. A connecting rod is fixed between the two chains. A push plate is fixed to the upper end of the connecting rod. A force-bearing plate is fixed to the lower end of the mine car. The push plate and the force-bearing plate are provided with mutually cooperating anti-detachment structures. An oiling mechanism is provided at one end of each chain. One of the rotating rods is connected to a drive assembly.
[0006] As a further improvement of this utility model: the anti-detachment structure includes a first locking block fixed to one side of the push plate, and a second locking block is provided on one side of the force-bearing plate, with the first locking block located above the second locking block.
[0007] As a further embodiment of this utility model: the oiling mechanism includes an oiling pipe fixed on the fixed frame and located at the end of the chain. The end of the oiling pipe away from the chain is connected to a grease tank. A sealing cap is screwed to the upper end of the grease tank. A high-pressure air pipe is fixed in the middle of the sealing cap. One end of the high-pressure air pipe is connected to an air compressor. A solenoid valve is installed on the oiling pipe.
[0008] As a further embodiment of this utility model: the drive assembly includes a reducer fixed to the outer wall of the fixed frame, the output end of the reducer is connected to one end of one of the rotating rods, the input end of the reducer is connected to a servo motor, and the servo motor is fixed to the outer wall of the reducer.
[0009] As a further improvement of this utility model: a fixing ear is provided at the bottom of the outer wall of the fixing frame, and a fixing hole is provided on the fixing ear.
[0010] As a further improvement of this utility model: the push plate and the connecting rod are connected by bolts, and the force-bearing plate is connected to the bottom end of the mine car by bolts.
[0011] The beneficial effects of this utility model are as follows:
[0012] The chain drives the connecting rod and push plate to move. The first locking block on the push plate locks above the second locking block, thereby moving the mine car and pulling it into the cage. When the connecting rod moves to the end of the fixed frame, the power output of the servo motor stops, and the mine car continues to move into the cage under the action of inertia. At the same time, the first and second locking blocks disengage. After the mine car is completely in the cage, the servo motor is restarted, so that the connecting rod moves to the front end of the fixed frame, ready to pull the next mine car. No manual pulling is required, and the positioning is accurate during the pulling process, making it less likely to fall off the mine car, thus solving the problem of poor efficiency.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Example 1, referring to Figure 1-6 A traction device for automatic loading of mine cars into a mine car includes a track 1 and a mine car 2. A fixed frame 3 is provided between the two tracks 1. Two rotating rods 5 are rotatably mounted on both ends of the inner wall of the fixed frame 3 via bearings. A sprocket 4 is fixed to both ends of the two rotating rods 5. A chain 6 is connected between the two sprockets 4 of the two rotating rods 5. A connecting rod 13 is fixed between the two chains 6. A push plate 14 is fixed to the upper end of the connecting rod 13. A force plate 8 is fixed to the lower end of the mine car 2. The push plate 14 and the force plate 8 are provided with mutually cooperating anti-detachment structures. An oiling mechanism is provided at one end of each of the two chains 6. One of the rotating rods 5 is connected to a drive assembly.
[0022] The anti-detachment structure includes a first locking block 15 fixed to one side of the push plate 14, and a second locking block 16 provided on one side of the force plate 8, with the first locking block 15 located above the second locking block 16.
[0023] The oiling mechanism includes an oiling pipe 9 fixed on the fixed frame 3 and located at the end of the chain 6. The end of the oiling pipe 9 away from the chain 6 is connected to a grease tank 11. A sealing cap is screwed to the upper end of the grease tank 11. A high-pressure air pipe 12 is fixed in the middle of the sealing cap. One end of the high-pressure air pipe 12 is connected to an air compressor. A solenoid valve 10 is installed on the oiling pipe 9.
[0024] The drive assembly includes a reducer 17 fixed to the outer wall of the fixed frame 3. The output end of the reducer 17 is connected to one end of one of the rotating rods 5. The input end of the reducer 17 is connected to a servo motor 18, and the servo motor 18 is fixed to the outer wall of the reducer 17.
[0025] The bottom of the outer wall of the fixed frame 3 is provided with a fixing ear 7, and the fixing ear 7 is provided with a fixing hole. The fixing ear 7 can be connected to the ground embedded part by anchor bolts to realize the installation of the fixed frame 3.
[0026] The push plate 14 is connected to the connecting rod 13 by bolts, and the force plate 8 is connected to the bottom of the mine car 2 by bolts. When the first locking block 15 and the second locking block 16 are worn excessively, it is convenient to replace the push plate 14 and the force plate 8.
[0027] Working principle: When the mine car moves to one side of the cage on track 1, the servo motor 18 is started, which drives the reducer 17 to rotate, which in turn drives the rotating rod 5, sprocket 4 and chain 6 to rotate, and drives the connecting rod 13 and push plate 14 to move. The first locking block 15 on the push plate 14 is locked above the second locking block 16, thereby driving the mine car 2 to move and pulling the mine car 2 into the cage. When the connecting rod 13 moves to the end of the fixed frame 3, the power output of the servo motor 18 is stopped, and the mine car 2 continues to move into the cage under the action of inertia. At the same time, the first locking block 15 and the second locking block 16 disengage. After the mine car 2 has completely entered the cage, the servo motor 18 is restarted, so that the connecting rod 13 moves to the front end of the fixed frame 3, which is ready to pull the next mine car 2.
[0028] The grease tank 11 can store semi-solid grease. By periodically opening the solenoid valve 10 and the external air compressor, high-pressure air enters the grease tank 11, which pushes the semi-solid grease in the grease tank 11 outward from the upper oil pipe 9, so that the grease is applied to the chain 6 to lubricate the chain 6 and reduce the wear of the chain 6 and sprocket 4.
[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
