Description

Technical Field

[0001] This application relates to the field of mineral conveying technology, and in particular to a mine car stopping and positioning device. Background Technology

[0002] Electric railcars are electrically powered rail transport devices used in mining environments. Powered by high-voltage cables or batteries, they utilize electric motors to drive the wheels, thus enabling transport along the rails. Suitable for both open-pit and underground mining environments, they must meet specific explosion-proof and dust-proof requirements. Electric railcars, driven by electricity, effectively improve automation efficiency in transporting raw ore within mining areas.

[0003] As per the instruction manual Figure 1 The track-mounted electric mining car shown is supported on the track by its rolling wheels. A discharge hopper is installed on the top side of the track. When transporting raw ore or other materials through the mining car, the mining car moves on the track to below the discharge hopper. After the mining car stops, the discharge hopper opens to let the ore fall into the mining car. Then the mining car moves on the track to transport the raw ore or other materials.

[0004] Currently, after the mine car moves to the bottom of the discharge hopper, due to the inertia of the mine car, it may continue to move forward a certain distance. If the track is not level, this distance will increase further, causing the material falling from the discharge hopper to fall outside the mine car. Figure 2 The condition shown causes the ore to spill outside the mine car, resulting in waste of the ore. The ore also falls into the track, making subsequent cleanup difficult. Summary of the Invention

[0005] To address the aforementioned problems, this application aims to provide a mine car stopping and material dropping positioning device, which limits the position of the mine car on the track to ensure that the mine car is vertically aligned with the material discharge hopper, thereby solving the problem of ore spilling outside the mine car due to misalignment with the material discharge hopper caused by the inertial movement of the mine car after it stops.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: a mine car stopping and positioning device, wherein the mine car is supported on the track by the rolling of its wheels, and a discharge hopper is provided on the top side of the track, characterized in that: the discharge positioning device includes a car-blocking component provided on the track and in contact with the wheels, the mine car and the discharge hopper are facing each other when the wheels are in contact with the car-blocking component, and an anti-reverse limiting component is also provided on the track to restrict the reverse movement of the mine car.

[0007] Preferably, the wheel-stopping component is a limiting block disposed on the track and capable of contacting the wheel.

[0008] Preferably, the limiting block has a sloping structure on the side near the wheel.

[0009] Preferably, the anti-reverse limiting component is a limiting plate provided on the track on the side of the limiting block near the wheel body, and a concave surface for embedding into the wheel body is provided on the limiting plate on the side near the limiting block.

[0010] The beneficial effects of this application are: the material dropping and positioning device limits and blocks the forward movement of the mine car due to its inertia by using a car-blocking component, thereby ensuring that the mine car is vertically aligned with the material discharge hopper. In this state, the material can be accurately dropped into the mine car through the material discharge hopper, thus solving the problem of material spilling out of the mine car due to misalignment with the material discharge hopper caused by the inertial movement of the mine car after it stops.

[0011] By using anti-reverse limiting components to restrict the reverse movement of the mine car after it comes into contact with the wheels, the reverse movement of the mine car is restricted, and the mine car is confined to the track position directly opposite the discharge hopper. This further restricts the position of the mine car and solves the problem of bidirectional movement of the mine car. Attached Figure Description

[0020] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of this application will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] See attached document Figures 1-8The diagram shows a mine car stopping and positioning device. The mine car 1 is supported on the track 3 by rolling wheels 2, and a discharge hopper 4 is provided on the top side of the track 3. After the mine car moves to the bottom of the discharge hopper 4, the discharge hopper opens and the ore falls into the mine car. After the mine car is full of ore, the mine car can move and transport on the track.

[0022] To address the issue of ore spillage outside the mine car due to misalignment between the mine car and the discharge hopper 4 caused by the increased travel distance of the mine car due to inertia and uneven tracks, this application includes a material discharge positioning device, such as... Figure 3 As shown, it includes a wheel-stopping component mounted on the track 3 and in contact with the wheel 2. When the wheel 2 is in contact with the wheel-stopping component, the mine car 1 is directly opposite the discharge hopper 4. When the mine car travels to the bottom of the discharge hopper 4 via electric drive, the wheel-stopping component contacts the wheel to limit and block the forward movement of the mine car due to its inertia, thus ensuring that the mine car is vertically aligned with the discharge hopper 4. In this state, the ore can be accurately poured into the mine car through the discharge hopper 4, thereby solving the problem of ore spilling outside the mine car due to misalignment caused by the inertial movement of the mine car after it stops.

[0023] When the wheels of the mine car come into contact with the blocking component, there is a certain impact. This impact causes the mine car to move in the opposite direction. Furthermore, if the track is not level, the mine car will move to the other side and become misaligned with the discharge hopper 4. After misalignment, the ore will also spill out of the mine car. Therefore, to solve this problem, an anti-reverse limiting component is also provided on the track 3 to restrict the reverse movement of the mine car 1. Under the impact of the wheels coming into contact with the blocking component, the reverse movement of the mine car is limited, thereby restricting the reverse movement of the mine car and confining the mine car to the track position directly opposite the discharge hopper 4.

[0024] Specifically, such as Figure 3 As shown, the vehicle-stopping component is a limiting block 5 installed on the track 3 and in contact with the wheel 2. When the vehicle travels to the bottom of the discharge hopper 4, the wheel 2 comes into contact with the limiting block 5, thereby overcoming the forward inertia of the mine car, so that the mine car stops in the passage and faces the discharge hopper 4. Then, the material is loaded through the discharge hopper 4. After loading, the mine car moves in the opposite direction through the electrically driven wheels to transport the ore.

[0025] During the movement of the mine car and due to inertia, after it comes into contact with the limiting block 5, there will be a certain amount of contact impact. This impact not only causes noise pollution, but repeated impacts can also cause the limiting block 5 to shift, such as... Figure 4 As shown, and considering the relative wear between the limiting block 5 and the wheel 2, therefore, to solve this problem, as... Figure 3As shown, the limiting block 5 has a sloping structure on the side near the wheel 2. When the wheel 2 contacts the limiting block 5, under the action of inertia, the wheel will roll upward along the sloping surface of the limiting block 5 at a certain arc. Figure 3 (As shown by the middle arrow a), thus buffering the direct impact of the wheel 2 on the limiting block 5, solving the noise impact, as well as the wear of the wheel 2 and the limiting block 5 caused by multiple impacts, and the movement of the limiting block 5.

[0026] To address the issue of reverse movement of the mine car's wheel 2 after it comes into contact with the limiting block 5, such as... Figure 5-8 As shown, the anti-reverse limiting component is a limiting plate 6 installed on the track near the wheel 2 side of the limiting block 5. A concave surface 6a is provided on the limiting plate 6 near the limiting block 5 to embed the wheel 2. Preferably, the front end of the limiting plate 6 also has a sloping structure, which facilitates the wheel 2 rolling along the slope onto the surface of the limiting plate 6. Then, under a small inertial force, the wheel can embed itself in the concave surface 6a of the limiting plate 6, thus limiting the wheel 2. After the ore is loaded, electric drive is used to detach the wheel 2 from the concave surface 6a and the limiting plate 6, allowing it to re-enter the track for transport. When the mine car's inertia increases due to the non-horizontal state of the guide rail, the wheel will continue to roll forward after being embedded in the concave surface 6a, causing the wheel 2 to contact the limiting block 5, thus buffering the mine car's inertia. The slope of the limiting block 5 further buffers the inertia of the mine car (and also includes the initial buffering effect of the wheel moving up the slope of the front end of the limiting plate 6 to the surface of the limiting plate 6). After the wheel rolls back from the slope of the limiting block 5, it falls into the concave surface 6a of the limiting plate 6, again achieving the alignment and positioning of the mine car. Overall, this solves the problem of mine car misalignment with the discharge hopper 4 due to inertia and unevenness of the track, causing ore spillage.

[0027] The principle of this application is as follows: Limiting blocks 5 and limiting plates 6 are set on the track. When the mine car travels on the track to the bottom of the discharge hopper, it moves along the slope of the front end of the limiting plate 6 to the surface of the limiting plate 6. The slope of the front end of the limiting plate 6 provides a first buffer against the inertia of the mine car. After rolling onto the concave surface 6a on the surface of the limiting plate 6, it is buffered a second time by inertia. If the inertia of the mine car can still overcome the limiting effect of the concave surface 6a, the wheel body contacts the slope of the limiting block 5 for a third buffer. Thus, after the wheel body falls from the slope of the limiting block 5 into the concave surface 6a of the limiting plate 6, the mine car is aligned and positioned. Then, the ore is loaded through the discharge hopper 4. After the ore is loaded, the wheel body 2 overcomes the embedding limiting effect of the concave surface 6a through electric drive, thereby detaching from the limiting plate 6 and traveling in the opposite direction on the track. The illustration in this application shows only one discharge hopper 4. In reality, a discharge hopper can also be set on the top of the mine car on the left, that is, multiple mine cars can be loaded with ore at the same time under one positioning action.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this application. Various changes and modifications may be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
