Description

Technical Field

[0001] This application relates to the field of track technology, and in particular to an underground multi-line crossover battery car track. Background Technology

[0002] In modern mining and underground engineering construction, underground battery-powered vehicles serve as crucial transportation tools, handling the transfer of ore, materials, and personnel. To meet the transportation needs of the complex underground environment, multi-line intersecting battery-powered vehicle track systems have emerged. This track system, through its multi-line intersecting layout, enables efficient connections between different work areas, improving transportation efficiency and reducing costs.

[0003] Currently, the most common underground multi-line intersecting battery-powered vehicle track adopts a three-end structure. This structure is formed by the intersection of three track lines.

[0004] Regarding the aforementioned technologies, the inventors believe that due to the limitations of the track connection structure design, the three-end structure requires manual assistance for complex track adjustments or vehicle scheduling when the electric vehicle changes tracks in the track intersection area. This is not only cumbersome and time-consuming, but also poses a high safety risk. Utility Model Content

[0005] The purpose of this application is to provide an underground multi-line crossing electric vehicle track to improve the problem that the track changing operation of electric vehicles in the track crossing area requires manual assistance for complex track adjustment or vehicle scheduling, which is cumbersome and time-consuming.

[0006] This application provides a multi-line crossover battery-powered vehicle track in underground mines, employing the following technical solution:

[0007] A multi-line intersecting battery-powered vehicle track for underground mining includes several pads. Two sets of intersecting tracks are arranged on the pads, each track including an inner rail and an outer rail. A diamond-shaped plate is provided at the intersection of the rubber sections of the two sets of tracks. The diamond-shaped plate has four transition plates, which are staggered and opposite to the inner rails located at both ends of the diamond-shaped plate. A directional rail that can fit against the inner wall of the outer rail is provided on both sides of the pad. A control box for driving the directional rail to move is provided on the pad.

[0008] By adopting the above technical solution, the track provides the basic path for the electric vehicle; the diamond-shaped plate and its four transition plates at the intersection of the tracks can accurately guide the wheels of the electric vehicle during track changes, so that the wheels can smoothly transition from the original track to the target track; the movable directional rails on both sides of the pad plate, together with the control box that drives their movement, realize the automation of track changing operation, eliminating the need for manual assistance, greatly simplifying the track changing process, reducing track changing time, and reducing the safety risks caused by manual operation.

[0009] Optionally, a set of triangular plates are symmetrically arranged on the rhombus plate, with two sides of the triangular plates being parallel to the transition plates at both ends of the rhombus plate.

[0010] By adopting the above technical solution, during the track-changing process of the electric vehicle, the triangular plate can fit against both sides of the wheel, playing a role in assisting in stabilizing the vehicle. This effectively improves the driving stability of the electric vehicle during track changing, reduces the possibility of the vehicle overturning due to track changing operations, and enhances the safety of the track system operation.

[0011] Optionally, the reversing rail is provided with a change rail plate on both sides of the center of the rhomboid plate.

[0012] By adopting the above technical solution, since the directional rail is prone to wear during frequent translation and rail changing operations, and the easy-change rail plate is fixed by welding, the easy-change rail plate can be directly replaced after the directional rail wears out, without the need to replace the entire directional rail. This reduces maintenance costs and difficulty, while ensuring the normal function of the directional rail, extending the service life of the track system, and improving the system's economy and practicality.

[0013] Optionally, the track is composed of multiple segments spliced ​​together, and a connecting sleeve is fitted at the joint of the track.

[0014] By adopting the above technical solution, the track is designed with multiple segments spliced ​​together and a connecting sleeve at the joint, which makes the installation and transportation of the track more convenient. The track length and direction can be flexibly adjusted according to the actual layout of the underground roadway. The setting of the connecting sleeve ensures the stability of the splice.

[0015] Optionally, the pad is provided with several fixing buckles on both sides of the track, and the fixing buckles are engaged with both sides of the track.

[0016] By adopting the above technical solution, the connection strength between the pad and the track is further enhanced, so that the track will not easily shift or shake when subjected to external forces such as pressure and friction generated by the electric vehicle, thereby ensuring the stability of the electric vehicle during operation and improving the overall structural strength and safety of the track system.

[0017] Optionally, a plurality of the pads are arranged in a series of intervals below the track, and when the pads are located below the track connection, they are arranged in a series of close fit.

[0018] By adopting the above technical solutions, the continuity of the support under the track is ensured, materials are reasonably saved, and the construction cost of the track system is reduced. At the same time, the closely spaced pads can provide better support for the track connection, ensuring the stability and durability of the track system.

[0019] Optionally, the pads intersect the tracks perpendicularly, and at the intersection of the two sets of tracks, the pads underneath are joined together in pairs.

[0020] By adopting the above technical solutions, the load-bearing capacity of the track intersection area is enhanced, which can better withstand the stress generated by the electric vehicle during track changing and ensure the structural stability of the track intersection area.

[0021] Optionally, the pad is provided with fixing plates at both ends of the rhombus plate, the fixing plates are attached to both ends of the rhombus plate, and the height of the fixing plates is less than that of the track.

[0022] By adopting the above technical solution, the fixing plate plays a role in limiting and supporting the diamond plate, reducing the displacement or shaking of the diamond plate when the battery car changes tracks, and further improving the reliability and stability of the track changing system.

[0023] In summary, this application includes at least one of the following beneficial technical effects of underground multi-line crossover battery car tracks:

[0024] 1. The track provides the basic path for the electric vehicle; the diamond-shaped plate and its four transition plates at the intersection of the tracks can accurately guide the wheels of the electric vehicle during track changes, so that the wheels can smoothly transition from the original track to the target track; the movable directional rails on both sides of the pad plate cooperate with the control box that drives their movement to realize the automation of track changing operation, without the need for manual assistance, greatly simplifying the track changing process, reducing track changing time, and reducing the safety risks caused by manual operation.

[0025] 2. Since the directional rail is prone to wear during frequent translation and rail changing operations, the easy-change rail plate is fixed by welding. After the directional rail wears out, the easy-change rail plate can be directly replaced without replacing the entire directional rail. This reduces maintenance costs and difficulty, while ensuring the normal function of the directional rail, extending the service life of the track system, and improving the system's economy and practicality.

[0026] 3. During the track-changing process of the electric vehicle, the triangular plate can fit against both sides of the wheel, playing a role in stabilizing the vehicle. This effectively improves the driving stability of the electric vehicle during track-changing, reduces the possibility of the vehicle overturning due to track-changing operations, and enhances the safety of the track system operation.

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1This application will be described in further detail below.

[0030] A multi-line intersecting underground battery-powered vehicle track, as referenced Figure 1 The system includes several base plates 1, which serve as the basic support components for the track 2. These base plates 1 are made of high-density wood and possess excellent resistance to compression and deformation. Two sets of intersecting tracks 2 are bolted onto the base plates 1. Each track 2 includes an inner track 21 and an outer track 22, both of which are I-beam shaped tracks 2, serving as the carrier for the wheels of the underground battery-powered vehicle. The track 2 is composed of multiple segments, each segment having a boss and a groove at its end. The track 2 connections are secured by connecting sleeves 6, which are welded to the track 2 to ensure a stable connection. Several fixing buckles 7 are located on both sides of the track 2 on the base plates 1. These metal buckles are welded to the base plates 1 at one end and interlock with the sides of the track 2 at the other end, further enhancing the connection strength between the track 2 and the base plates 1.

[0031] Reference Figure 1 A diamond-shaped plate 3, made of steel plate, is installed at the intersection of the two sets of tracks 2 to guide the electric vehicle to smoothly change tracks in the intersection area of ​​tracks 2. The diamond-shaped plate 3 has four transition plates 31, which are inclined metal plates. One end of each transition plate is welded to the diamond-shaped plate 3, and the other end is staggered with the inner rails 21 located at both ends of the diamond-shaped plate 3. The inclination angle of the transition plates 31 is precisely designed to allow the electric vehicle wheels to smoothly transition from one track 2 to another. A base plate 1 is located at both ends of the diamond-shaped plate 3, with fixing plates 8. The fixing plates 8 are fixedly connected to the base plate 1 by bolts, and are close to both ends of the diamond-shaped plate 3. Their height is less than that of the track 2, thus limiting the movement of the diamond-shaped plate 3.

[0032] Reference Figure 1 Several pads 1 are arranged in sequence at intervals below the track 2. When the pads 1 are below the connection of the track 2, the pads 1 are arranged in sequence to ensure the continuity of the support below the track 2. The pads 1 intersect the track 2 perpendicularly. At the intersection of two sets of track 2, the pads 1 below them are spliced ​​together in pairs to form a stable cross support structure.

[0033] Reference Figure 1 A set of triangular plates 32 are symmetrically arranged on the rhombus plate 3. The triangular plates 32 are made of triangular metal plates, with two sides arranged parallel to the transition plates 31 at both ends of the rhombus plate 3 and fixedly connected to the rhombus plate 3 by welding. This arrangement can fit the sides of the wheel, improve the stability of the vehicle when the electric vehicle changes tracks, and prevent the vehicle from overturning.

[0034] Reference Figure 1The pad 1 is located on both sides of the rhomboid plate 3 and has directional rails 4 that can fit against the inner wall of the outer rail 22. The directional rails 4 are made of the same material and shape as the outer rail 22 and are installed on the pad 1 through a sliding connection of slide rail and slider. The pad 1 is equipped with a control box 5 that drives the directional rails 4 to move. The control box 5 is equipped with an electric push rod, and the output end of the electric push rod is fixedly connected to the directional rails 4. By controlling the extension and retraction of the electric push rod, the directional rails 4 can be moved. When the directional rails 4 are not in contact with the outer rail 22, the two sets of rails 2 do not change direction. When the directional rails 4 are in contact with the outer rails 22 on both sides, the two sets of rails 2 change direction differently.

[0035] Reference Figure 1 The directional rail 4 is provided with a change rail plate 41 on both sides of the center of the rhombus plate 3. The directional rail 4 is provided with a slot on both sides of the center of the rhombus plate 3. The change rail plate 41 is made of metal plate and is fixed in the slot by welding. The two sides of the change rail plate 41 are not connected to the directional rail 4 of the track 2.

[0036] The implementation principle of this application embodiment is as follows:

[0037] In actual use, during normal operation, the electric vehicle wheels travel along the inner rail 21 and outer rail 22 of the I-shaped track. When changing tracks, the electric push rod in the control box 5 receives the command and extends or retracts, causing the change track 4, which is connected to the pad plate 1 through the slide rail slider, to move horizontally, providing transition guidance. At the same time, the four transition plates 31 on the rhomboid plate 3, which are precisely designed at angles, guide the wheels to smoothly transition from the original track 2 to the target track 2. The fixing plates 8 at both ends of the rhomboid plate 3 restrict the displacement of the rhomboid plate 3, and the triangular plates 32 symmetrically welded on both sides fit against the sides of the wheel to enhance the stability of track changing. Thus, the vehicle can smoothly change tracks and operate efficiently between multiple lines.

[0038] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
