Description

Technical Field

[0001] This utility model relates to the field of mining railway technology, and in particular to a guiding device for mining railway transportation. Background Technology

[0002] Mine railway transportation refers to a mode of transportation that uses railway lines to transport raw materials or finished ores mined from mines to designated locations. It features large transportation capacity, high efficiency, relatively low cost, and low environmental pollution, making it an important means for mining enterprises to improve material transportation efficiency and ensure production continuity.

[0003] Existing wheel flange guides for mining railway transportation use a fixed structure, which cannot adapt to rails with different gaps. This makes them prone to derailment under complex and variable track conditions. They also generally suffer from poor shock absorption performance, which means that the vibrations generated by the train during operation cannot be effectively absorbed, thus aggravating the wear and tear on the track and vehicles. Therefore, improvements are needed. Utility Model Content

[0004] One objective of this invention is to provide a guiding device for mining railway transportation. This invention addresses the problems mentioned above, where existing wheel flange guides for mining railway transportation employ a fixed structure, which cannot adapt to rails with different clearances, leading to a risk of derailment under complex and variable track conditions. Furthermore, they generally suffer from poor shock absorption performance, resulting in the inability to effectively absorb vibrations generated during train operation, thereby exacerbating wear and tear on the tracks and vehicles.

[0005] A guiding device for mine railway transportation according to an embodiment of the present utility model includes:

[0006] An adjustment mechanism, installed at the bottom of a mining railway transport vehicle, is used to adjust the gap between the wheelset and the track. The adjustment mechanism includes a mounting frame, inside which a first extension column is movably arranged. A second extension column is movably arranged at one end of the first extension column. Arc-shaped grooves and a first guide groove are respectively opened at the upper and lower ends of the first and second extension columns for reverse linear movement between the first and second extension columns. A first guide rod is connected to the first extension column and the second extension column. A second guide rod is movably arranged inside the first guide groove. A first hydraulic push cylinder is fixedly arranged between the first and second extension columns.

[0007] A shock-absorbing mechanism, installed at the ends of the first and second extension columns in the adjusting mechanism, is used to reduce vibration during mining railway transportation. The shock-absorbing mechanism includes a support frame with symmetrically arranged grooves on its inner side. A sliding plate is slidably arranged inside the grooves. Dampers are symmetrically fixed between the sliding plate and the support frame. A buffer sleeve is fixedly installed at the upper end inside the support frame. A second hydraulic cylinder is fixedly installed at the top of the support frame. A second piston is fixedly installed at the output end of the second hydraulic cylinder. A contact-type liquid level trigger is fixedly installed at the bottom of the second piston. An L-shaped connecting rod is slidably arranged at the bottom of the buffer sleeve. A first piston is fixedly installed at the top of the L-shaped connecting rod. A trapezoidal wheel is rotatably arranged at one end of the L-shaped connecting rod. A contact-type trigger is fixedly arranged in a ring at the outer edge of the trapezoidal wheel.

[0008] Preferably, the first guide rod is fixedly disposed inside the mounting bracket, and the first guide rod is movably disposed inside the arc-shaped groove.

[0009] Preferably, the second guide rod is fixedly disposed inside the mounting bracket.

[0010] Preferably, the support frame is fixedly connected to the first extension column and the second extension column respectively.

[0011] Preferably, both the first piston and the second piston are movably disposed inside the buffer sleeve, which is filled with liquid.

[0012] Preferably, a limit plate is fixedly installed on the side of the trapezoidal vehicle near the L-shaped connecting rod.

[0013] Preferably, the contact trigger is electrically connected to the first hydraulic push cylinder, and the contact level trigger is electrically connected to the second hydraulic push cylinder.

[0014] Preferably, the mounting bracket, the first extension column, the second extension column, and the trapezoidal wheel are all made of chromium-molybdenum alloy steel and have a tungsten carbide coating on their surfaces.

[0015] The beneficial effects of this utility model are:

[0016] This invention effectively solves the problem that existing wheel flange guides used in mining railway transportation cannot adapt to rails with different clearances through its adjustable mechanism. The adjustable mechanism includes a mounting frame, a first extension column, a second extension column, and a first hydraulic push cylinder. The first and second extension columns are connected to the first guide groove, the first guide rod, and the second guide rod through an arc-shaped sliding groove to achieve reverse linear motion. This allows the wheelset to be precisely adjusted according to the actual clearance of the rail under the drive of the hydraulic push cylinder. The adjustment is triggered by a contact trigger on the wheelset after contacting the rail, and then the first hydraulic push cylinder pushes the trapezoidal vehicle outward. The adjustment process can be achieved through hydraulic power, improving the efficiency and convenience of adjustment. Therefore, this device reduces the risk of derailment and improves transportation safety. At the same time, because it can adjust the clearance between the wheelset and the rail in real time, it also reduces the wear of the rail and wheels and extends their service life.

[0017] This invention utilizes a shock-absorbing mechanism comprising a support frame, a chute, a sliding plate, a damper, a buffer sleeve, a second hydraulic push cylinder, and a first and second piston. During the operation of a mining railway transport vehicle, when the wheelset encounters uneven track or changes in clearance, the sliding plate in the shock-absorbing mechanism slides within the chute. Simultaneously, the damper absorbs vibration energy, reducing the vibration transmitted to the vehicle body. The buffer sleeve is filled with liquid, and the first and second pistons move within the liquid, further absorbing and dispersing vibration energy. Furthermore, when the contact-type liquid level trigger contacts the liquid, it drives the second hydraulic push cylinder to reset the L-shaped connecting rod to its initial position. This design effectively improves shock absorption performance, reduces vibration generated during train operation, and protects the track and vehicle from excessive wear. Through the application of this shock-absorbing mechanism, the stability and safety of mining railway transportation are significantly enhanced. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0025] refer to Figure 1-4 A guiding device for mining railway transportation, comprising:

[0026] Adjustment mechanism 1, installed at the bottom of the mining railway transport vehicle, is used to adjust the gap between the wheelset and the track. Adjustment mechanism 1 includes a mounting frame 101, inside which a first extension column 102 is movably mounted. A second extension column 103 is movably mounted at one end of the first extension column 102. Arc-shaped sliding grooves 202104 and a first guide groove 105 are respectively provided at the upper and lower ends of the first extension column 102 and the second extension column 103 for reverse linear movement. A first guide rod 106 is connected between the first extension column 102 and the second extension column 103. A second guide rod 107 is movably mounted inside the first guide groove 105. A first guide rod 107 is fixedly mounted between the first extension column 102 and the second extension column 103. A hydraulic push cylinder 108 is provided. The adjustment mechanism 1 includes a mounting frame 101, a first extension column 102, a second extension column 103, and a first hydraulic push cylinder 108. The first extension column 102 and the second extension column 103 are connected to the first guide groove 105, the first guide rod 106, and the second guide rod 107 through an arc-shaped slide groove 202104 to achieve reverse linear motion. This allows the wheelset to be precisely adjusted according to the actual gap of the track under the drive of the hydraulic push cylinder. The contact trigger 210 set on the wheelset is triggered after contacting the track. Then, the first hydraulic push cylinder 108 is used to push the trapezoidal vehicle outward. The adjustment process can be realized by hydraulic power, which improves the efficiency and convenience of adjustment.

[0027] The shock absorption mechanism 2 is installed at the ends of the first extension column 102 and the second extension column 103 in the adjustment mechanism 1, and is used to achieve shock absorption during mine railway transportation. The shock absorption mechanism 2 includes a support frame 201, with symmetrically arranged grooves 202 on the inner side of the support frame 201. A sliding plate 203 is slidably arranged inside the grooves 202. A damper 204 is symmetrically fixed between the sliding plate 203 and the support frame 201. A buffer sleeve 205 is fixedly arranged at the upper end inside the support frame 201. A second hydraulic push cylinder 211 is fixedly arranged at the top of the support frame 201. A second piston 212 is fixedly arranged at the output end of the second hydraulic push cylinder 211. A contact-type liquid level trigger 213 is fixedly arranged at the bottom of the second piston 212. An L-shaped connecting rod 206 is slidably arranged at the bottom of the buffer sleeve 205. A first piston 207 is fixedly installed at the top of the rod 206. A trapezoidal wheel 208 is rotatably installed at one end of the L-shaped connecting rod 206. A contact trigger 210 is fixedly installed in a ring at the outer edge of the trapezoidal wheel 208. During the operation of the mining railway transport vehicle, when the wheelset encounters uneven track or changes in clearance, the slide plate 203 in the shock absorption mechanism 2 slides in the slide groove 202. At the same time, the damper 204 absorbs vibration energy and reduces the vibration transmitted to the vehicle body. The buffer sleeve 205 is filled with liquid 214. The first piston 207 and the second piston 212 move in the liquid 214 to further absorb and disperse vibration energy. When the contact liquid level trigger 213 contacts the liquid 214, the L-shaped connecting rod 206 is reset to the initial position by driving the second hydraulic push cylinder 211.

[0028] Example 1: The first guide rod 106 is fixedly installed inside the mounting frame 101 and is movably installed inside the arc-shaped slide groove 202104. The second guide rod 107 is fixedly installed inside the mounting frame 101. The first guide rod 106 is fixed inside the mounting frame 101 and movably installed within the arc-shaped slide groove 202104, ensuring the stability and flexibility of the guide rod. Simultaneously, the second guide rod 107 is also fixed inside the mounting frame 101, working in conjunction with the first guide rod 106 to maintain the precise guidance of the adjustment mechanism 1. The support frame 201 is fixedly installed with the first extension column 102 and the second extension column 103 respectively. The first piston 207 and the second piston 212 are both movably installed inside the buffer sleeve 205, which is filled with liquid 214. This design allows the shock absorption mechanism 2 to effectively absorb and disperse the vibrations generated during train operation, improving the shock absorption performance and reliability of the entire guiding device.

[0029] Example 2: A limit plate 209 is fixedly installed on the side of the trapezoidal vehicle near the L-shaped connecting rod 206. The contact trigger 210 is electrically connected to the first hydraulic push cylinder 108, and the contact level trigger 213 is electrically connected to the second hydraulic push cylinder 211. This configuration allows the hydraulic system to perform precise cylinder pushing actions according to the signal of the trigger. The mounting bracket 101, the first extension column 102, the second extension column 103, and the trapezoidal wheel 208 are all made of chromium-molybdenum alloy steel and have a tungsten carbide coating on the surface, which improves the wear resistance and corrosion resistance of the components and enhances the strength and durability of the overall structure, thereby improving the vehicle's performance under complex working conditions.

[0030] Working principle: The device achieves precise adjustment of the gap between the wheelset and the track through the adjustment mechanism 1. When the contact trigger 210 on the wheelset contacts the track, the trigger sends a signal. The first hydraulic push cylinder 108 receives the signal and pushes the trapezoidal vehicle outward. Precise adjustment of the wheelset is achieved through the reverse linear motion connection of the first extension column 102 and the second extension column 103 (achieved by the first guide rod 106 and the second guide rod 107). Simultaneously, during vehicle movement, the shock absorption mechanism 2 slides within the groove 202 via the slide plate 203, and the damper 2... 04 Absorbs vibration energy and reduces vibration transmission. The liquid 214 in the buffer sleeve 205, together with the first piston 207 and the second piston 212, further absorbs and disperses vibration energy. When the contact-type liquid level trigger 213 contacts the liquid 214, it drives the second hydraulic push cylinder 211 to reset the L-shaped connecting rod 206, ensuring the shock absorption effect. In addition, the limit plate 209, the electrically connected trigger and the hydraulic push cylinder, etc., together ensure the stability and adjustment accuracy of the device, and improve the wear resistance, corrosion resistance and overall structural strength and durability.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
