[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0025] The following describes a mining transport device 100 according to an embodiment of the present invention with reference to the accompanying drawings.

[0026] like Figures 1-6 As shown, a mining transport device 100 according to an embodiment of the present invention includes a main rail 1 , a transport assembly 2 and a rerail assembly 3 .

[0027] The main rail 1 is suitable for being arranged in the lane and along the length direction of the lane (such as Figure 1 Specifically, as shown in the left and right directions Figure 1 As shown, the main rail 1 is the basic supporting structure of the transport device. It is made of high-strength alloy steel and has an I-shaped cross-section. The main rail 1 is fixed to the tunnel floor through sleepers and extends in a straight line or curve along the length of the tunnel. The surface of the main rail 1 is quenched and has a hardness of HRC28-32 to resist long-term rolling wear of the wheels.

[0028] The transport assembly 2 is arranged on the main rail 1 and is movable along the length direction of the main rail 1. The transport assembly 2 is suitable for transporting coal. Figure 1 As shown, the transport assembly 2 includes a car body, double-flange wheels and a power system. The whole is arranged above the main rail 1 and moves through wheel-rail contact. The car body adopts a welded steel structure, and double-flange wheels are provided at the bottom of the car body. The rim height of the double-flange wheels is 30mm-35mm to prevent derailment. The power system is arranged on the car body and connected to the wheels, so that the power system drives the wheels to rotate, thereby transporting the coal in the tunnel.

[0029] The mining transport device 100 has a first state and a second state. In the first state, the transport component 2 is movable on the main rail 1 in the longitudinal direction of the main rail 1, and the rerailing component 3 is arranged on the transport component 2. In the second state, the transport component 2 is derailed, and the rerailing component 3 is arranged on the main rail 1 to guide the derailed transport component 2 back to the main rail 1 through the rerailing component 3. Specifically, Figure 1-Figure 2 As shown, the mining transport device 100 has two working states. The first state is the normal transport state, in which the transport component 2 runs stably on the main rail 1, and the rerailing component 3 is installed under the rear of the vehicle body through a hook or placed in the vehicle body. The second state is the derailment and rerailing state. When the transport component 2 derails due to reasons such as roadway deformation, sudden stop impact, etc., the operator removes the rerailing component 3 from the vehicle body and moves it to the side of the main rail 1 through a hydraulic cylinder. The rerailing component 3 is then installed on the main rail 1. At this time, the rerailing component 3 forms a continuous transition surface with the top surface of the main rail 1. The derailed wheels climb along the rerailing component 3 and return to the main rail 1 without the need for external lifting equipment.

[0030] The mining transport device 100 of the embodiment of the present invention is provided with a rerailing assembly 3. When the transport assembly 2 is operating normally, the rerailing assembly 3 can be set on the transport assembly 2 and move with the transport assembly 2 in the main rail 1. When the transport assembly 2 is derailed, the rerailing assembly 3 can be removed from the transport assembly 2 and installed on the main rail 1, so that the transport assembly 2 is returned to the main rail 1 through the rerailing assembly 3. Compared with the related art, there is no need to use a jack and a crowbar to lift the vehicle and place it on the main rail 1. The operation is simple, the labor intensity is low, time and labor are saved, and the demand for efficient production can be met.

[0031] In some embodiments, the rerailing assembly 3 includes a first rail 31 and a second rail 32 connected to each other. In the second state, the first rail 31 is provided on the main rail 1, and the second rail 32 is provided on one side of the main rail 1, so that the transport assembly 2 moves to the first rail 31 through the second rail 32 and is transported to the main rail 1 through the first rail 31. Specifically, Figures 1-4 As shown, in the second state, the first rail 31 is installed above the rail head of the main rail 1, the axis of the first rail 31 coincides with the axis of the main rail 1, and the second rail 32 is arranged on one side of the main rail 1 (the left or right side is selected according to the tunnel space). The wheels can smoothly transition from the second rail 32 to the first rail 31, and then be transported to the main rail 1 through the first rail 31.

[0032] In some embodiments, the first track 31 includes a first section 311 and a second section 312, the second section 312 is provided between the first section 311 and the second track 32, and both ends of the second section 312 are connected to the first section 311 and the second track 32, respectively, in a width direction orthogonal to the main rail 1 (e.g., Figure 1 In the projection plane (in the front-to-back direction shown in FIG), the first section 311 extends from top to bottom and is inclined in a direction away from the second section 312, and the free end of the first section 311 is provided on the main rail 1, the second section 312 is a horizontal section extending along the length direction of the main rail 1, and the second section 312 is spaced apart from the main rail 1 in the vertical direction, the second rail 32 extends from top to bottom and is inclined in a direction away from the second section 312, and the free end of the second rail 32 is suitable for being provided on the bottom plate of the roadway. Specifically, as shown in FIG. Figure 4As shown, in the projection plane of the orthogonal and front-to-back directions, the first section 311 and the second section 312 are both arranged above the main rail 1, the first section 311 is a guiding inclined section and the first section 311 extends from top to bottom and tilts to the left, the left end of the first section 311 is arranged on the main rail 1, the second section 312 is a horizontal transition section, the axis of the second section 312 is parallel to the axis of the main rail 1, the second rail 32 is arranged on one side of the main rail 1 and the second rail 32 is arranged on the bottom plate of the tunnel, the left end of the second rail 32 is connected to the right end of the second section 312, the second rail 32 extends from top to bottom and tilts to the right, and the right end of the second rail 32 is arranged on the bottom plate of the tunnel, and the derailed transport component 2 is transported to the main rail 1 through the second rail 32, the second section 312, and the first section 311 in sequence.

[0033] In the projection plane perpendicular to the up-down direction, the first rail 31 extends from one end of the second rail 32 in a direction away from the rail and is inclined toward the direction adjacent to the main rail 1. The second rail 32 extends along the length direction of the main rail 1 and the second rail 32 and the main rail 1 are spaced apart in the width direction of the main rail 1. Specifically, Figure 1-3 As shown, in the projection plane orthogonal to the up and down directions, the first rail 31 extends from left to right and tilts backward, and the second rail 32 extends from left to right and is parallel to the main rail 1, so that the derailed transport component 2 can be transported to the main rail 1 through the second rail 32 and the first rail 31.

[0034] The second track 32 serves as the starting point for the rerailing operation. It extends downward from top to bottom and tilts away from the second section 312, forming a slope extending from the roadway floor to the second section 312. After derailment, the wheels located on the floor first contact and roll upward along this slope. The inclined design of the second track 32 effectively compensates for the height difference between the roadway floor and the main rail 1, providing an easily accessible and reasonably sloped starting point for the derailed wheels at the lowest point to climb, greatly simplifying the wheel positioning and rerailing initiation process. Its free end is firmly fixed to the roadway floor, ensuring the stability of the entire rerailing path starting point. Its design, arranged to the side of the main rail 1, provides flexibility, allowing for left or right installation according to the actual space in the roadway, and is highly adaptable.

[0035] The second section 312 is located between the first section 311 and the second track 32, and is used to receive the wheels climbing up from the second track 32 and transport them horizontally and stably to the starting end of the first section 311. The second section 312 eliminates the slope changes in the key transition area, providing an extremely stable and bump-free support surface for the wheels, effectively preventing the risk of secondary derailment due to unstable center of gravity at the climbing apex. Its axis is strictly parallel to the axis of the main track 1 and maintains a precise vertical spacing of 150mm±2mm, ensuring the accuracy and controllability of the wheel trajectory during horizontal movement, and laying a solid foundation for smoothly entering the inclined first section 311 and finally returning to the main track 1.

[0036] The first section 311 is as the terminal point of the derailing wheel rerailing path, and it extends from top to bottom and to the structure away from the second section 312 direction tilts, forms a guiding surface of the decline with gentle gradient. The derailing wheel first contacts and rolls downward along its surface, and the descending type tilting design has utilized gravity assistance, so that the wheel can naturally and smoothly slide down along the inclined plane after breaking away from the horizontal transition section (second section 312), greatly reducing the required active driving force or the thrust of the rerailing end section, so that the transportation system is more steadily moved on the main rail 1.

[0037] In some embodiments, within a projection plane orthogonal to the lengthwise direction of the main rail 1, the cross-sectional area of ​​the free end of the first section 311 gradually decreases in a direction away from the second section 312, and / or the cross-sectional area of ​​the free end of the second guide rail gradually decreases in a direction away from the second section 312. Specifically, the cross-sectional area of ​​the left end of the first section 311 is wedge-shaped, gradually decreasing from right to left, allowing the transport assembly 2 to move smoothly onto the main rail 1, and the cross-sectional area of ​​the right end of the second guide rail is wedge-shaped, gradually decreasing from left to right, allowing the transport assembly 2 to move smoothly onto the second guide rail.

[0038] In some embodiments, the mining transport device 100 further includes a first support member 4 and a second support member 5 .

[0039] The first support member 4 is provided between the second section 312 and the main rail 1 and is located at the connection between the first section 311 and the second section 312. The first support member 4 is used to support the connection between the first section 311 and the second section 312. The second support member 5 is provided between the second track 32 and the bottom plate of the tunnel and is located at the connection between the second track 32 and the first track 31. The second support member 5 is used to support the second track 32. Specifically, as Figure 5 As shown, the first support member 4 and the second support member 5 can both be I-beams. The first support member 4 is arranged below the connection between the first section 311 and the second section 312 and is connected to the connection between the first section 311 and the second section 312. The second support member 5 is located on one side of the second track 32 and is arranged at the intersection of the second track 32 and the first track 31. In the second state, the first support member 4 is arranged on the main rail 1 and the second support member 5 is arranged on the tunnel floor. Thus, the first support member 4 supports the connection between the first section 311 and the second section 312, ensuring the rigidity and stability of the connection between the first section 311 and the second section 312, effectively resisting the downward pressure and vibration caused by wheel rolling, preventing the horizontal section from sinking, tilting or deforming, and ensuring the accuracy and stability of the wheel running trajectory in the key transition area.

[0040] The second support member 5 is provided at the junction of the second track 32 and the first track 31, maintaining a smooth connection between the second track 32 and the second section 312. This ensures the reliability of the wheel transition from the inclined section to the horizontal section, improves the overall stability of the entire rerailing path under dynamic loads, and disperses the pressure on the base plate to prevent localized collapse.

[0041] In some embodiments, the mining transport device 100 further includes a first positioning member 6 and a second positioning member 7 .

[0042] The first positioning member 6 is provided on the first track 31. In the second state, the first positioning member 6 is connected to the main track 1 so as to position the first track 31. Specifically, Figure 1 As shown, the first positioning member 6 is fixed to the left end of the first rail 31. In the second state, the first rail 31 and the main rail 1 are positioned by the first positioning member 6 to ensure that the axis of the first rail 31 coincides with the axis of the main rail 1.

[0043] The second positioning member 7 is provided on the second rail 32. In the second state, the second positioning member 7 is located between the second rail 32 and the main rail 1 and the second positioning member 7 is connected to one side of the main rail 1 so as to position the second rail 32. Specifically, Figure 1 As shown, one end of the second positioning member 7 is arranged on one side of the second rail 32. In the second state, the second positioning member 7 is located between the second positioning member 7 and the main rail 1 and the other end of the second positioning member 7 is connected to the main rail 1, thereby preventing the second positioning member 7 from deviating.

[0044] In some embodiments, the first positioning member 6 includes a first clamping plate and a second clamping plate. The first clamping plate and the second clamping plate are both provided on the first rail 31 and are spaced relative to each other along the width direction of the first rail 31. A portion of the first clamping plate and a portion of the second clamping plate are located below the rail. In the second state, the first clamping plate and the second clamping plate are clamped on the main rail 1. Specifically, the first clamping plate and the second clamping plate can both be provided at the free end of the first rail 31 and are located on the front and rear sides of the first rail 31. The lower end of the first clamping plate and the lower end of the second clamping plate extend out of the first rail 31, and the lower end of the first clamping plate, the lower end of the second clamping plate and the lower end surface of the first rail 31 define a clamping cavity. In the second state, the lower end of the first clamping plate and the lower end of the second clamping plate are respectively clamped on the front and rear sides of the main rail 1, installing the first rail 31 on the main rail 1, and effectively preventing the first rail 31 from shaking or displacement during subsequent operations.

[0045] In some embodiments, the second positioning member 7 includes a positioning plate, which is provided on one side of the second rail 32. In the second state, the positioning plate is located between the second rail 32 and the main rail 1 and is connected to the main rail 1. Specifically, the positioning plate is a vertical plate extending in the front-to-back direction, one end of which is connected to one side of the second rail 32, and a magnet is provided on the other side of the second positioning plate. In the second state, when the positioning plate is close to the main rail 1, the positioning plate is adsorbed on the main rail 1 by the magnet, thereby making the relative position between the main rail 1 and the second rail 32 more stable, providing a strong guarantee for the normal operation of the entire mechanical system.

[0046] In some embodiments, there are multiple rerailing assemblies 3, and the transport assembly 2 includes multiple transport units. In the first state, the multiple rerailing assemblies 3 are arranged on the multiple transport units in a one-to-one correspondence. Specifically, as shown in FIG (), the multiple transport units are sequentially connected along the left and right directions. In the first state, the multiple transport units are all arranged on the main rail 1 and each transport unit is provided with at least one rerailing assembly 3, so that the transport unit drives the rerailing assembly 3 to move. In the second state, depending on the derailment of the transport assembly 2, the rerailing assembly 3 of the derailed transport unit can be removed to allow the transport assembly 2 to return to the main rail 1.

[0047] In some embodiments, at least one of the outer peripheral surface of the transport component 2 and the outer peripheral surface of the rerail component 3 is coated with an anti-corrosion coating. Specifically, the outer peripheral surface of the transport component 2 and the outer peripheral surface of the rerail component 3 can be coated with an anti-corrosion coating to prevent the transport component 2 and the rerail component 3 from being corroded in the tunnel, thereby extending the service life of the transport component 2 and the rerail component 3.
