Technical Field
[0001] This utility model relates to the field of track positioning technology, and in particular to a track positioning device for mining cars. Background Technology
[0002] Mine car track positioning devices are widely used in industrial settings such as mines, metallurgy, and ports as positioning devices for mine cars. This positioning device used on mine car tracks is a non-contact positioning technology based on the principle of electromagnetic induction. This positioning device requires the installation of a Gray busbar during use.
[0003] The common method for installing Gray busbars is to install the Gray busbar base and bracket along the side of the track, and then install the Gray busbar next to the bracket. The installation methods for the base and bracket include threaded installation or welding installation. In actual production and mine car operation, the position of the mine car track positioning device will also change with the changes in the mine car's working environment. As a component of the mine car track positioning device, the installation position of the Gray busbar base and bracket needs to be changed and needs to be quickly disassembled and assembled in conjunction with the track.
[0004] In view of this, we propose a track positioning device for mine cars for quick installation and disassembly of the Gray busbar base. Utility Model Content
[0005] The purpose of this utility model is to solve the problem in the prior art that the installation position of the Gray busbar base and bracket needs to be changed and needs to be quickly disassembled and assembled with the track, and to propose a track positioning device for mine cars.
[0006] To achieve the above objectives, this utility model provides the following technical solution: A track positioning device for a mining car includes a track, a pile foundation fixedly mounted at the bottom of the track, a slider slidably mounted at the top of the track, a mining car fixedly mounted at the top of the slider, a fixing frame fixedly mounted at the bottom of the mining car, an induction coil disposed inside the fixing frame, a receiver disposed at one end of the induction coil, and a snap-fit assembly disposed on the pile foundation. The snap-fit assembly includes: The base is fixedly installed on the side wall of the pile foundation. One end of the base is fixedly connected to one end of the connecting plate. A rotating shaft is rotatably installed inside the connecting plate. A circular plate is fixedly installed on the other end of the connecting plate. The first spring is fixedly installed on the other end of the circular plate. There are two sets of the first spring. The other ends of the two sets of the first spring are respectively fixedly installed with a first movable plate and a second movable plate. The first movable plate and the second movable plate are rotatably installed on the outside of the rotating shaft. The other end of the pile foundation is snapped with a wire placement plate. A locking block is fixedly installed on one end of the wire placement plate close to the connecting plate. An adhesive assembly is disposed inside a wiring plate, and a Gray busbar is placed inside the wiring plate.
[0007] Preferably, the fastening component includes a second spring fixedly installed inside the cable tray, and a rectangular plate fixedly installed at the other end of the second spring for adapting to different sizes of Gray busbars.
[0008] Preferably, the pile foundation is provided in multiple sets, and each set of pile foundations is provided with a base, a connecting plate, a rotating shaft, a circular plate, a first spring, a first movable plate, a second movable plate, a line plate, and a locking block, so that the base on each set of pile foundations can be better installed and disassembled.
[0009] Preferably, the inner walls of the first and second movable plates are arc-shaped, and the arc-shaped outer wall of the locking block fits into the arc-shaped inner wall of the first and second movable plates, so that the locking block is more firmly engaged after entering the inner wall of the first and second movable plates.
[0010] Preferably, two sets of rectangular plates are provided, and the Gray busbar is placed between the two sets of rectangular plates, so that the Gray busbar can be better fixed.
[0011] This utility model has the following advantages compared with the prior art: 1. The mine car track positioning device is equipped with a snap-fit assembly for quick installation and disassembly of the Gray busbar base. By pressing the snap-fit block against the first and second movable plates, the first spring is forced to expand and contract, changing the gap between the first and second movable plates. After the snap-fit block is fitted into the interior of the first and second movable plates, a snap-fit is formed. Compared with threaded installation and welding installation, the Gray busbar base in the mine car positioning device is easier to disassemble and install, saving loading and unloading time and improving work efficiency.
[0012] 2. The track positioning device for the mine car is equipped with a clamping component to stabilize the Gray busbars of different sizes in the mounting plate. When Gray busbars of different sizes are placed in the mounting plate, they will compress the springs connected to the rectangular plate, forming elastic potential energy, making the Gray busbars more closely adhere to the rectangular plate and forming a clamping effect, thereby adapting to Gray busbars of different sizes and achieving a stabilizing effect.

[0017] like Figure 1 and 2 As shown, a track positioning device for a mine car is used for positioning a mine car 4 on a track 1. The car 4 can move on the track 1. The track 1 includes a track 1, a pile foundation 2 is fixedly installed at the bottom of the track 1, and a slider 3 is slidably installed on the top of the track 1. The mine car 4 is fixedly installed on the top of the slider 3. like Figure 3 and 4 As shown, the device also includes a fixing frame 5, which is fixedly installed on the bottom of the mine car 4. The fixing frame 5 has a slot, and an induction coil 6 is provided in the slot. A receiver 7 is provided at one end of the induction coil 6. like Figure 5 and 6As shown, the device also includes a snap-fit assembly, which includes a base 8 fixedly installed on the side wall of the pile foundation 2. One end of the base 8 is fixedly connected to one end of a connecting plate 9. A rotating shaft 10 is rotatably installed inside the connecting plate 9. One end of the connecting plate 9 is fixedly installed to one end of a circular plate 11. One end of the circular plate 11 is fixedly installed to one end of a first spring 12. Two sets of first springs 12 are provided. The other ends of the two sets of first springs 12 are respectively fixedly installed to a first movable plate 13 and a second movable plate 14. The first movable plate 13 and the second movable plate 14 are rotatably installed outside the rotating shaft 10. The inner walls of the first movable plate 13 and the second movable plate 14 are arc-shaped. A wire placement plate 15 is snap-fitted onto the other side wall of the pile foundation 2. A locking block 16 is fixedly installed on one end of the wire placement plate 15 close to the connecting plate 9. The fastening assembly includes a second spring 17 fixedly installed inside the cable placement plate 15. A rectangular plate 18 is fixedly installed at the other end of the second spring 17. Multiple sets of the second spring 17 are provided inside the cable placement plate 15. Two sets of the rectangular plates 18 are provided inside the cable placement plate 15. A Gray busbar 19 is placed between the two sets of rectangular plates 18.
[0018] The specific working principle of this utility model is as follows: The movement of the mine car 4 on the track 1 is driven by the variable frequency motor inside the slider 3. The slider 3 moves on the track 1, causing the mine car 4 to move linearly along the track 1. At the same time, a Gray busbar 19 is laid parallel on the pile foundation 2. The Gray busbar 19 achieves vehicle positioning by generating electromagnetic induction with the induction coil 6 installed on the mine car 4. The induction coil 6 and the receiver 7 are installed on the mine car 4. When an alternating current is passed through the induction coil 6, an alternating magnetic field is generated nearby. Since the induction coil 6 and the receiver 7 are close to the Gray busbar 19, the Gray busbar 19 is approximately in this alternating, uniformly distributed magnetic field. Each pair of core wires of the Gray busbar 19 in the alternating magnetic field will generate an induced electromotive force. A stable reference signal is generated. The signal generated by the address line varies depending on its relative position with the magnetic field. By judging multiple pairs of address line signals, the positions of the induction coil 6 and receiver 7 along the length of the Gray bus 19 are determined, thereby determining the position of the mine car 4. Since the Gray bus 19 needs to be close to the induction coil 6 and receiver 7, a base 8 and a wiring plate 15 are usually installed on the pile foundation 2 to suspend and place the Gray bus 19. The snap-fit assembly is used for quick installation and removal of the straight plate 15. The base 8 and the wiring plate 15 are designed for quick release. When the wiring plate 15 needs to be installed, the snap-fit block on the wiring plate 15 is aligned with the arc-shaped inner wall between the first movable plate 13 and the second movable plate 14. In the initial state of the first spring 12, the first movable plate 14 is in the middle position. 3. The gap between the first movable plate 13 and the second movable plate 14 is small. When the locking block 16 is used to press the gap between the first movable plate 13 and the second movable plate 14, the first spring 12 will be compressed by the rotational force of the first movable plate 13 and the second movable plate 14. As the first spring 12 contracts, the gap between the first movable plate 13 and the second movable plate 14 gradually widens, allowing the locking block 16 to enter the arc-shaped inner wall of the first movable plate 13 and the second movable plate 14. After the locking block 16 is fully inserted, it releases the contact with the first movable plate 13 and the second movable plate 14, causing the first spring 12 to no longer be stressed and return to its initial state. This allows the first movable plate 13 and the second movable plate 14 to engage with the locking block 16, and the wire plate 15 and the base 8 form a quick-release engagement. The structure allows for the placement of the Gray busbar 19, enabling quick installation and disassembly between the base 8 and the cable tray 15, thus improving work efficiency. When the cable tray 15 needs to be disassembled, the locking block 16 is pulled out from between the first movable plate 13 and the second movable plate 14 to release the locking state. At the same time, the tight assembly allows Gray busbars 19 of different sizes to be placed more securely in the cable tray 15. In the initial state, the two sets of rectangular plates 18 are supported by the second spring 17, and the gap between the two sets of rectangular plates 18 is small. When the Gray busbar 19 is placed between the two sets of rectangular plates 18, the two sets of rectangular plates 18 will squeeze the second spring 17, making the two sets of rectangular plates 18 fit the Gray busbar 19 more closely, thereby achieving the effect of stabilizing and adapting to Gray busbars 19 of different sizes.
