Description

TECHNICAL FIELD

[0001] The present application relates to the field of mining equipment, in particular to a transportation system. BACKGROUND

[0002] The shuttle car is a commonly used material storage and transfer equipment in the process of coal mine roadway tunneling, which has the characteristics of large storage capacity and fast transfer speed, and is particularly suitable for short-distance transportation in low space, uneven terrain and large turning angle scenes.

[0003] In the related art, the shuttle car has low transportation safety and poor transportation efficiency. SUMMARY

[0004] The present application is based on the discovery and understanding of the inventors of the following facts and problems:

[0005] In the related art, as coal resource mining gradually goes from the surface to the underground, the coal seam changes greatly in ups and downs, and the mining difficulty increases. When the shuttle car transports materials in the underground, the phenomenon of insufficient climbing power occurs, which affects the safety and efficient production of the coal mine. In addition, the floor of the tunneling working face has not been hardened, and the reciprocating transportation of the shuttle car will cause the ground to have uneven and pitted road surface, which seriously affects the transportation safety and efficiency of the vehicle. Artificial repair and filling are required, which has the characteristics of high labor intensity and high operation danger, and restricts the safety production of the coal mine.

[0006] The present application aims to at least solve one of the technical problems in the related art.

[0007] To this end, an embodiment of the present application proposes a transportation system with high transportation efficiency and strong climbing power.

[0024] A transportation system 100 according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0025] As shown in Figures 1-4 , the transportation system 100 according to an embodiment of the present application comprises a shuttle vehicle 1, a driving assembly 2 and a pushing assembly 3.

[0026] The shuttle car 1 is suitable to be arranged in a roadway and to move in the roadway between a first position and a second position, at the first position, the shuttle car 1 is suitable to cooperate with a coal mining device so that the coal collected by the coal mining device flows into the shuttle car 1, at the second position, the shuttle car 1 is suitable to cooperate with a transportation device so that the coal in the shuttle car 1 flows into the transportation device and is transported outside the roadway by the transportation device. Specifically, as shown in Figure 1 and Figure 2 , the shuttle car 1 is arranged inside a coal mine roadway and moves between a coal mining device (for example, a coal mining machine, a continuous miner) and a transportation device (for example, a belt conveyor, a scraper conveyor), in an actual coal mining operation process, the coal mining device continuously performs cutting operation on the coal, when the shuttle car 1 is at the first position, the shuttle car 1 cooperates with the coal mining device, the coal mined by the coal mining device can flow into the shuttle car 1 for temporary storage, which improves the continuity and efficiency of the coal mining operation, then the shuttle car 1 moves to the second position, the shuttle car 1 is docked with the transportation device, so that the coal stored in the shuttle car 1 flows into the transportation device and is then transported to a designated location, completing the coal transfer work.

[0027] The driving assembly 2 is arranged at one end of the shuttle car 1 towards the coal mining device, and is used to provide driving force for the shuttle car 1. Specifically, as shown in Figure 1 , the driving assembly 2 is arranged at the front end of the shuttle car 1, when a larger slope is encountered and climbing difficulty or difficulty in passing the climbing section occurs due to insufficient power, the driving assembly 2 is turned on to supplement power for the shuttle car 1, so that the shuttle car 1 moves smoothly between the first position and the second position.

[0028] The flattening assembly 3 is arranged at one end of the shuttle car 1 towards the transportation device, and is used to perform flattening treatment on the roadway floor to eliminate protrusions or depressions of the roadway floor, the transportation assembly has a first state and a second state, in the first state, at least one of the driving assembly 2 and the flattening assembly 3 works, in the second state, at least one of the driving assembly 2 and the flattening assembly 3 is turned off. Specifically, as shown in Figure 2 and Figure 3 , the flattening assembly 3 is arranged at the rear end of the shuttle car 1, when the coal mine roadway floor is uneven due to continuous miner operation, equipment movement or other factors, and there are many pits and depressions, which affects the coal transportation and the safety and efficiency of subsequent operation, the flattening assembly 3 is attached to the roadway floor, and the flattening assembly 3 moves with the shuttle car 1 to perform flattening operation on the roadway floor, the flattening assembly 3 scrapes the protruding part to fill and flatten the pit and depression, so that the roadway floor becomes smooth and flat, ensuring the stable transportation of the coal.

[0029] In the first state, at least one of the driving assembly 2 and the flattening assembly 3 is in a working state. When the shuttle car 1 climbs a slope or encounters complex terrain, the driving assembly 2 is started to provide additional power, ensuring that the shuttle car 1 moves smoothly, or if the roadway bottom surface is uneven, the flattening assembly 3 moves with the shuttle car 1 to scrape and flatten the protrusions and fill the pits, ensuring safe and efficient coal transportation and subsequent operation, and the two work alone or simultaneously as needed.

[0030] In the second state, the driving assembly 2 and the flattening assembly 3 are both in a stopped state. When the coal mining operation is relatively stable and the power and bottom surface flatness requirements are not high, if the shuttle car 1 is moving on a flat section and the self-power is sufficient, the driving assembly 2 can be turned off to save energy and reduce equipment wear and tear, and if the roadway bottom surface is flat and there is no new damage, the flattening assembly 3 can be stopped to reduce costs and maintenance difficulty, allowing the transportation system 100 to operate economically and with low energy consumption.

[0031] The transportation system 100 of the embodiment of the present application is provided with the driving assembly 2. In actual coal mining operations, when the shuttle car 1 has a large load and faces a large slope, it is easy to have difficulty climbing the slope or even be unable to pass through the climbing section due to insufficient power. At this time, the driving assembly 2 is started to drive the shuttle car 1 to move smoothly between the first position (where the coal is received in cooperation with the coal mining machine) and the second position (where the coal is transported in cooperation with the conveyor), ensuring the continuity and efficiency of the coal mining and transportation process, avoiding the interruption of the entire operation process caused by the shutdown of the shuttle car 1, and improving the efficiency of the coal mining operation. When the shuttle car 1 is empty or has a small load or is running on a flat section, the driving assembly 2 can be stopped, reducing unnecessary energy consumption of the driving assembly 2, reducing operating costs, and improving overall operation efficiency.

[0032] The transportation system 100 of the embodiment of the present application is provided with the flattening assembly 3. In coal mining, continuous mining machine operation and the like can easily make the roadway bottom surface uneven and have many pits, affecting coal transportation. The flattening assembly 3 starts in the first state and moves downward to contact the roadway bottom surface, moves with the shuttle car 1 to scrape and flatten the protrusions and fill and flatten the pits, making the bottom surface smooth and flat, ensuring stable coal transportation, and ensuring the smoothness of the entire mining and transportation process. When the bottom surface has been flattened or does not need to be flattened, it can be switched to the second state to move upward and be separated from the bottom surface, allowing the shuttle car 1 to normally perform other tasks such as coal transportation, preventing unnecessary wear and tear or interference to the bottom surface, and flexibly adapting to different operation requirements, thereby reducing equipment failure and accident risks caused by uneven bottom surfaces, improving operation safety, avoiding the tediousness and high-intensity labor of manually processing the pit bottom surface, reducing labor costs, and improving overall operation efficiency.

[0033] The transportation system 100 of the embodiment of the present application is provided with a driving assembly 2 and a flattening assembly 3. The flattening assembly 3 can level the working ground, eliminate pits and bumps, and create a good driving foundation for the transportation equipment, thereby reducing the additional loss and failure risk of the equipment due to uneven ground. The driving assembly 2 adjusts the power output according to the load and terrain. The cooperation of the driving assembly 2 and the flattening assembly 3 makes the transportation process coherent and efficient, improves the transportation speed and stability, reduces energy waste, reduces equipment maintenance costs, enhances operation safety, and reduces personnel safety risks.

[0034] In some embodiments, the driving assembly 2 includes a hydraulic winch 21 and a steel wire rope (not shown in the figure). The hydraulic winch 21 is arranged at one end of the shuttle car 1 facing the coal mining device. One end of the steel wire rope is connected to the hydraulic winch 21. In the first state, the other end of the steel wire rope is arranged in the roadway and located at the front end of the shuttle car 1. The hydraulic winch 21 works to wind the steel wire rope on the hydraulic winch 21, so that the steel wire rope pulls the shuttle car 1 to move between the first position and the second position. In the second state, the other end of the steel wire rope is arranged on the shuttle car 1. Specifically, as shown in Figure 1 the figure, the hydraulic winch 21 is arranged at the front end of the shuttle car 1. One end of the steel wire rope is connected to the hydraulic winch 21. In the first state, the other end of the steel wire rope is arranged in the roadway. The hydraulic winch 21 is started to work, and the steel wire rope is wound on the hydraulic winch 21. With the continuous rotation of the hydraulic winch 21, the steel wire rope is gradually tightened, thereby generating a pulling force to pull the shuttle car 1 to move between the second position and the first position. In the second state, i.e., when the shuttle car 1 is in an empty load, a small load, or runs on a flat section, the other end of the steel wire rope is arranged on the shuttle car 1. At this time, the shuttle car 1 moves between the first position and the second position by relying on its own power or other auxiliary power, and simultaneously drives the steel wire rope to move.

[0035] In some embodiments, as shown in Figure 1 the figure, the driving assembly 2 further includes a dust cover 22. The dust cover 22 is arranged on the shuttle car 1, and the hydraulic winch 21 is arranged in the dust cover 22. Specifically, the coal mine roadway is full of dust. If a large amount of dust adheres to the hydraulic winch 21, it will gradually invade the internal components and hydraulic system of the hydraulic winch 21, accelerate the wear of parts, reduce the performance of the equipment, and shorten the service life. Therefore, by arranging the dust cover 22 on the hydraulic winch 21, the dust can be effectively blocked, the damage of the dust to the hydraulic winch 21 can be reduced, the hydraulic winch 21 can always be in a good working state, the maintenance frequency and cost can be reduced, the driving assembly 2 can stably and reliably provide power for the shuttle car 1, and the coal transportation operation can be efficiently performed.

[0036] In some embodiments, the flattening assembly 3 includes a mounting frame 31 and a scraper 32.

[0037] The mounting frame 31 is arranged at one end of the shuttle car 1 facing the transportation device, and the mounting frame 31 is rotatable between the third position and the fourth position relative to the width direction of the shuttle car 1. Specifically, as shown in Figures 2-4 the mounting frame 31 is hinged at the rear end of the shuttle car 1, and the mounting frame 31 is rotated on the shuttle car 1 between the third position and the fourth position in the left-right direction.

[0038] The scraper 32 is arranged on the mounting frame 31, in the first state, the mounting frame 31 is in the third position, the scraper 32 is in contact with the roadway floor, so as to be used for pushing the roadway floor, in the second state, the mounting frame 31 is in the fourth position, the scraper 32 is separated from the roadway floor. Specifically, as shown in Figures 2-4 the scraper 32 is a vertical plate and is arranged on the mounting frame 31, the lower end of the scraper 32 protrudes from the lower end of the mounting frame 31, in the first state, the mounting frame 31 moves downward to the third position, so that the lower end of the scraper 32 is in contact with the roadway floor, with the movement of the shuttle car 1, the scraper 32 smoothly slides on the roadway floor, and the protruding part on the floor is scraped flat, the pits and holes are filled, the originally uneven roadway floor becomes smooth, the smooth roadway floor can reduce the bumping and shaking of the shuttle car 1 during driving, reduce equipment wear and tear, improve transportation efficiency, and also avoid coal spilling due to uneven floor and reduce resource waste.

[0039] In the second state, the mounting frame 31 is rotated upward to the fourth position, and the scraper 32 is separated from the roadway floor, when the shuttle car 1 drives on the road section which has been pushed flat and the floor is relatively flat, or when the pushing operation is not needed and only the shuttle car 1 is needed to transport coal normally, the scraper 32 is lifted and separated from the floor, which can reduce the friction between the scraper 32 and the floor and prolong the service life of the scraper 32. At the same time, it can also avoid the collision between the scraper 32 and the hard object on the floor in unnecessary cases, and reduce the risk of equipment damage.

[0040] In some embodiments, the transportation system 100 further has a third state, so that when the shuttle vehicle 1 is insufficient in climbing power, the scraper 32 is in abutment with the bottom surface of the roadway, so as to increase the sliding resistance of the shuttle vehicle 1. Specifically, when the shuttle vehicle 1 is driving in the roadway and encounters a climbing section, due to factors such as large roadway slope, wet road surface, or excessive load, the shuttle vehicle 1 may be insufficient in climbing power. The transportation system 100 switches to the third state, and the flattening assembly 3 is in abutment with the bottom surface of the roadway downward. With the increase of the contact area and the contact pressure of the flattening assembly 3 with the bottom surface, the flattening assembly 3 provides support force and friction force for the shuttle vehicle 1, the support force can share part of the gravity of the shuttle vehicle 1, and the load of the wheels is reduced, so that the wheels can better play a driving role. Thus, by setting the third state of the flattening assembly 3, effective assistance is provided for the shuttle vehicle 1 when it is insufficient in climbing power, and the climbing ability and driving stability of the shuttle vehicle 1 in the complex roadway environment are greatly improved, and the continuity and efficiency of the coal mine production and transportation are ensured.

[0041] In some embodiments, in the projection plane perpendicular to the length direction of the shuttle vehicle 1, the projection of the shuttle vehicle 1 is located in the scraper 32. Specifically, in the projection plane perpendicular to the front-rear direction, the size of the scraper 32 in the left-right direction is greater than that of the shuttle vehicle 1 in the left-right direction, and the shuttle vehicle 1 is located in the scraper 32. Thus, when the scraper 32 moves with the shuttle vehicle 1, it can fully play its role of leveling the material, avoiding the situation that part of the area cannot be effectively treated due to the small size of the scraper 32, thereby ensuring the comprehensiveness and efficiency of the leveling operation, and providing reliable protection for the leveling of the roadway bottom surface.

[0042] In some embodiments, the flattening assembly 3 further comprises a hydraulic telescopic rod 33, both ends of the hydraulic telescopic rod 33 are rotatably connected with the shuttle vehicle 1 and the flattening assembly 3 respectively, in the first state, the hydraulic telescopic rod 33 is elongated to drive the flattening assembly 3 to move downward, and in the second state, the hydraulic telescopic rod 33 is shortened to drive the flattening assembly 3 to move upward. Specifically, as shown in Figure 3 the base of the hydraulic telescopic rod 33 is hinged with the rear end surface of the shuttle vehicle 1, and the piston rod of the hydraulic telescopic rod 33 is rotatably connected with the flattening assembly 3, in the first state, the hydraulic telescopic rod 33 is elongated to drive the flattening assembly 3 to move downward, so that the flattening assembly 3 is arranged on the bottom plate of the roadway, and in the second state, the hydraulic telescopic rod 33 is shortened to drive the flattening assembly 3 to move upward, so that the flattening assembly 3 is separated from the bottom plate of the roadway.

[0043] In some embodiments, the scraper 32 includes a first plate 321 and a second plate 322, which are arranged sequentially along the width direction of the shuttle 1. The first plate 321 extends away from the second plate 322 and is inclined toward the adjacent shuttle 1, and / or the second plate 322 extends away from the first plate 321 and is inclined toward the adjacent shuttle 1. The free ends of the first plate 321 and the second plate 322 are rotatably connected to the shuttle 1.

[0044] Specifically, such as Figure 4 As shown, the first plate 321 and the second plate 322 are both vertical plates arranged sequentially in the left-right direction. The first plate 321 is located to the left of the second plate 322, and the right end of the first plate 321 is connected to the left end of the second plate 322. The left end of the first plate 321 and the right end of the second plate 322 are both hinged to the rear end of the shuttle 1. The first plate 321 extends from left to right and tilts forward, while the second plate 322 extends from right to left and tilts forward, thus making the scraper 32 form a V-shape. On the one hand, the V-shaped design of the scraper 32 expands the contact range between the scraper 32 and the bottom surface of the tunnel, improving work efficiency. On the other hand, the opening direction of the V-shape is adapted to the traveling direction of the shuttle 1, allowing the material to orderly converge towards the center along the slope of the V-shape during the scraping and smoothing process, avoiding the material from scattering everywhere and reducing the difficulty of subsequent cleaning work. In addition, the V-shaped structure can enhance the stability of the smoothing component 3, better resist external interference during operation, and ensure the uniformity and consistency of the smoothing effect.

[0045] In some embodiments, the extending direction of the first plate 321 and the extending direction of the second plate 322 intersect at an angle of 120°-150°. Specifically, the included angle between the first plate 321 and the second plate 322 can be any of 120°, 130°, 140°, or 150°. When the included angle is less than 120°, the included angle between the first plate 321 and the second plate 322 will be too small, and the V-shaped opening will be too narrow. In order to ensure the leveling effect of the scraper 31, the length of the first plate 321 and the second plate 322 needs to be increased. Only a sufficiently long first plate 321 and the second plate 322 can cover a larger area under the narrow opening, thereby achieving an effective leveling operation. This not only increases the cost of materials, but also increases the processing difficulty during the processing process due to the increased length of the first plate 321 and the second plate 322, resulting in a higher processing cost for the scraper 31. When the included angle is greater than 150°, the V-shaped opening will be too wide, making it easy for materials to scatter to the outside of the scraper 31, increasing the cleaning volume and operation time.

[0046] In some embodiments, the transportation system 100 further includes a first detection component (not shown in the figure) and a second detection component (not shown in the figure).

[0047] The first detection component is arranged in the driving component 2, so that the first detection component detects the driving force of the driving component 2. Specifically, the first detection component can be a tension sensor and is arranged at the connection position between the hydraulic winch 21 and the steel wire rope, so that the traction force of the driving component 2 is detected by the first detection component, and when the traction force of the driving component 2 detected by the first detection component approaches or exceeds the safe bearing range of the detection component, the operator is reminded to take measures, such as reducing the running speed, reducing the load and the like.

[0048] The second detection component is arranged in the pushing component 3, so as to detect the pushing force of the pushing component. Specifically, the second detection component is a stroke displacement sensor and is arranged in the hydraulic telescopic rod 33, the position of the pushing component 3 is adjusted by the stroke displacement sensor, so that the accurate control of the pushing component 3 is realized, the pothole road surface is smoothed, the manual shovel operation is avoided, the labor intensity of the workers is reduced, and the safety production in the coal mine is ensured.

[0049] The working process of the transportation system 100 with the smoothing function in the embodiment is as follows: when the shuttle car 1 is used for material transfer in the coal mine, the whole equipment has a large weight, the ground contact pressure is large, the operation ground is not hardened, the shuttle car 1 repeatedly travels back and forth in a certain space, the floor of the underground roadway often appears to be concave, and in severe cases, the passing vehicles can be deeply stuck, which seriously affects the safety production in the coal mine. The height of the scraper 31 is adjusted by the hydraulic telescopic rod 33, the stroke displacement sensor is arranged in the hydraulic telescopic rod 33, the accurate control of the scraper 31 is realized, the pothole road surface is smoothed, the manual shovel operation is avoided, the labor intensity of the workers is reduced, and the safety production in the coal mine is ensured.

[0050] When a large slope is encountered, the phenomenon of climbing difficulty or difficulty in passing the climbing section due to insufficient power is prone to occur. Therefore, when a large slope is encountered, the worker ties the steel wire rope on the hydraulic winch 21 to a fixed point on the slope, the steel wire rope is retracted by the hydraulic winch 21 to assist the shuttle car 1 to climb the slope, the climbing ability of the equipment is enhanced, and the safety production performance of the coal mine is improved. At the same time, the hydraulic winch can assist the traction equipment and carry the materials, so that the use of the shuttle car 1 is expanded.
