Description
Technical Field
[0001] This utility model relates to the field of mine transportation technology, specifically a mine car equipped with a vehicle blocking structure. Background Technology
[0002] In underground mining operations, mine cars are crucial tools for transporting materials and are commonly used for transferring various materials within underground tunnels. When a mine car is transported to a designated location and placed on the trackless tunnel floor, to prevent runaway mine cars and related safety accidents, regulations require the installation of car stoppers at the front and rear of the car. Currently, there are two main types of car stoppers commonly used in underground mines: one uses two wooden planks forming a "cross" shape, inserted diagonally into the bottom of the mine car to block it; the other is a welded triangular stool, which also prevents runaway mine cars by being inserted diagonally into the bottom of the car.
[0003] However, actual investigations revealed that mine cars were frequently parked without wheel stops, posing a significant safety hazard to mine operations. The main reasons for this are: first, the number of mine cars on site is large, while the number of wheel stops is insufficient to meet the need for each car to be equipped with one; second, the storage location for the wheel stops is too far from where the mine cars are placed, making it inconvenient for workers to carry them over long distances; and third, the gaps between the mine cars are too small, resulting in insufficient space to install wheel stops.
[0004] Therefore, we propose a mining car with a braking structure. Utility Model Content
[0005] The purpose of this invention is to provide a mining car with a vehicle-stopping structure to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a mine car equipped with a vehicle-stopping structure, comprising: A base, the top of which is fixedly connected to a transport vehicle box, and rollers are symmetrically installed on the outer side of the base; A locking mechanism, comprising a fixing ring, wherein the base has fixing rings symmetrically and equidistantly fixedly connected to the bottom of the base, and a triangular wheel stop is rotatably installed between two of the fixing rings; The cleaning mechanism includes a protective box, inside which a cleaning groove is provided. A rotating rod is symmetrically and rotatably installed inside the cleaning groove, and a brush is installed on the outside of the rotating rod.
[0007] Preferably, the locking mechanism further includes gears, with gears fixedly connected to the outer sides of both ends of the triangular wheel stopper. A connecting plate is installed at the bottom of the base, and the bottom of the connecting plate has a toothed groove, which meshes with the outer side of the gear. Symmetrically fixed fixing rings at the bottom of the base provide rotational support for the triangular wheel stopper. After the bidirectional motor starts, it drives the bidirectional threaded rod to rotate. Since the bidirectional threaded rod meshes with the sliding block in the sliding groove, and the sliding block is fixed to the connecting plate through the support plate, the rotation of the bidirectional threaded rod will drive the two connecting plates to move towards each other.
[0008] Preferably, the base has symmetrical sliding grooves at its bottom, and a bidirectional threaded rod is rotatably installed at the center of the base bottom. A sliding block is slidably installed inside the sliding groove, and the outer ends of both ends of the bidirectional threaded rod are meshed with the interior of the sliding block. A support plate is fixedly connected to one end of each of the two connecting plates, and the support plate is fixedly connected to the interior of the sliding block. A bidirectional motor is installed at the bottom center of the base, and the output end of the bidirectional motor is fixedly connected to the bidirectional threaded rod. The toothed grooves at the bottom of the connecting plates mesh with the gears at both ends of the triangular car stop, causing the triangular car stop to rotate downwards around the fixed ring until it inserts into the tunnel floor, forming a stable blockage. At this point, the locking mechanism, through the meshing relationship between the gears and the toothed grooves, locks the triangular car stop in the blocking position, preventing it from shifting and avoiding mine car runaway.
[0009] Preferably, the cleaning mechanism further includes pulleys. Pulleys are symmetrically installed on one side of the protective box, and one end of the rotating rod passes through the inside of the protective box and is fixedly connected to the pulleys. Connecting belts are installed on the outer sides of the two pulleys. A rotating motor is installed on the other side of the protective box, and the output end of the rotating motor is fixedly connected to the rotating rod. The protective box provides a physical shield to the tip of the triangular car stopper, preventing accidental injury to workers during mine car operation or worker handling, thus providing safety protection. On the other hand, the cleaning groove inside the protective box provides space for cleaning operations. After the rotating motor is started, its output end drives the rotating rod to rotate. The pulley on the rotating rod drives another rotating rod to rotate synchronously via the connecting belt. The brushes on the outer sides of the two rotating rods rotate accordingly, thoroughly cleaning the front end of the triangular car stopper that has retracted into the protective box, removing attached coal slag, mud, and other impurities.
[0010] Preferably, a dust collection box is installed at the bottom of the protective box.
[0011] Preferably, both the bidirectional motor and the rotary motor are electrically controlled and connected by an external power supply.
[0012] Compared with the prior art, the beneficial effects of this utility model are: Addressing the pain points of traditional car stoppers and improving operational safety: Effectively solves the problems of insufficient quantity of traditional car stoppers (cross-shaped wooden blocks and triangular stool blocks), the distance between storage and mine car parking locations leading to workers being reluctant to move them, and the small gaps between mine cars making them impossible to install. It avoids mine car runaway accidents caused by the lack of car stoppers and significantly reduces safety hazards in mine transportation operations.
[0013] The vehicle blocking operation is convenient and efficient, reducing labor costs: The locking mechanism uses a bidirectional motor, bidirectional threaded rod, gears and tooth grooves to realize the automatic lowering and retraction of the triangular vehicle blocking device. There is no need for manual handling or manual setting of the vehicle blocking device, which reduces manual operation steps and labor intensity, saves operation time, and improves the efficiency of vehicle blocking operation.
[0014] To ensure reliable vehicle blocking and extend equipment lifespan: The cleaning mechanism can promptly clean the front end of the retrieved triangular vehicle blocker, removing attached coal slag, mud, and other impurities, ensuring that the triangular vehicle blocker can smoothly insert into the roadway floor when blocking vehicles next time, avoiding the impact of impurities on the blocking effect; at the same time, the protective box can physically protect the tip of the triangular vehicle blocker, preventing damage to the tip when not in use, extending the service life of the vehicle blocker, and preventing the tip from scratching workers, ensuring the safety of personnel operation.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1-4 A mining car equipped with a vehicle-stopping structure includes: A base 1, on the top of which a transport vehicle box 2 is fixedly connected, and rollers 3 are symmetrically installed on the outer side of the base 1; A locking mechanism, comprising a fixing ring 4, wherein the base 1 is symmetrically and equidistantly fixedly connected to the bottom of the base 1, and a triangular wheel stopper 5 is rotatably installed between the two fixing rings 4; The cleaning mechanism includes a protective box 14, a cleaning groove 15 is provided inside the protective box 14, a rotating rod 16 is symmetrically rotatably installed inside the cleaning groove 15, and a brush 17 is installed on the outside of the rotating rod 16.
[0019] Please see Figure 1-4 The locking mechanism also includes gears 6. Gears 6 are fixedly connected to the outer sides of both ends of the triangular wheel stopper 5. A connecting plate 7 is installed at the bottom of the base 1. The bottom of the connecting plate 7 has a toothed groove 8, and the connecting plate 7 is engaged with the outer side of the gear 6 through the toothed groove 8. The fixing rings 4 symmetrically fixed at the bottom of the base 1 provide rotational support for the triangular wheel stopper 5. After the bidirectional motor 13 is started, it drives the bidirectional threaded rod 10 to rotate. Since the bidirectional threaded rod 10 engages with the sliding block 11 in the sliding groove 9, and the sliding block 11 is fixed to the connecting plate 7 through the support plate 12, the rotation of the bidirectional threaded rod 10 will drive the two connecting plates 7 to move towards each other.
[0020] Please see Figure 1-4 The base 1 has symmetrical sliding grooves 9 on its bottom. A bidirectional threaded rod 10 is rotatably installed at the center of the bottom of the base 1. A sliding block 11 is slidably installed inside the sliding groove 9, and the outer ends of both ends of the bidirectional threaded rod 10 are meshed with the inside of the sliding block 11. One end of each of the two connecting plates 7 is fixedly connected to a support plate 12, and the inside of the support plate 12 is fixedly connected to the sliding block 11. A bidirectional motor 13 is installed at the bottom center of the base 1, and the output end of the bidirectional motor 13 is fixedly connected to the bidirectional threaded rod 10. The toothed groove 8 at the bottom of the connecting plate 7 meshes with the gears 6 at both ends of the triangular car stopper 5, causing the triangular car stopper 5 to rotate downwards with the fixed ring 4 as the fulcrum until it inserts into the tunnel floor and forms a stable blockage with the floor. At this time, the locking mechanism locks the triangular car stopper 5 in the blocking position through the meshing relationship between the gears 6 and the toothed groove 8, preventing it from shifting and avoiding mine car runaway.
[0021] Please see Figure 1-4The cleaning mechanism also includes pulleys 18. Pulleys 18 are symmetrically installed on one side of the protective box 14, and one end of the rotating rod 16 passes through the inside of the protective box 14 and is fixedly connected to the pulleys 18. Connecting belts 19 are installed on the outer sides of the two pulleys 18. A rotating motor 20 is installed on the other side of the protective box 14, and the output end of the rotating motor 20 is fixedly connected to the rotating rod 16. The protective box 14 can physically shield the tip of the triangular car stopper 5, preventing accidental injury to workers during mine car operation or worker operation, thus providing safety protection. On the other hand, the cleaning groove 15 inside the protective box 14 provides space for cleaning operations. After starting the rotating motor 20, its output end drives the rotating rod 16 to rotate. The pulley 18 on the rotating rod 16 drives the other rotating rod 16 to rotate synchronously through the connecting belt 19. The brushes 17 on the outer sides of the two rotating rods 16 rotate accordingly, thoroughly cleaning the front end of the triangular car stopper 5 that has retracted into the protective box 14, removing attached coal slag, mud, and other impurities.
[0022] Please see Figure 1-4 The bottom of the protective box 14 is equipped with a dust collection box 21.
[0023] Please see Figure 1-4 Both the bidirectional motor 13 and the rotary motor 20 are electrically controlled and connected by an external power supply.
[0024] Working principle: When a mine car needs to be stopped at a designated location in the roadway, the locking mechanism is activated to achieve precise lowering and locking of the triangular car stopper 5. In the locking mechanism, the fixing rings 4 symmetrically fixed at the bottom of the base 1 provide rotational support for the triangular car stopper 5. After the bidirectional motor 13 is started, it drives the bidirectional threaded rod 10 to rotate. Since the bidirectional threaded rod 10 meshes with the sliding block 11 in the sliding groove 9, and the sliding block 11 is fixed to the connecting plate 7 through the support plate 12, the rotation of the bidirectional threaded rod 10 will drive the two connecting plates 7 to move towards each other. The toothed groove 8 at the bottom of the connecting plate 7 meshes with the gears 6 at both ends of the triangular car stopper 5, causing the triangular car stopper 5 to flip downwards with the fixed ring 4 as the fulcrum until it inserts into the roadway floor and forms a stable blockage with the floor. At this time, the locking mechanism locks the triangular car stopper 5 in the blocking position through the meshing relationship between the gear 6 and the toothed groove 8, preventing it from shifting and avoiding the mine car from running away. When the mine car needs to continue to travel, the bidirectional motor 13 rotates in the opposite direction, driving the connecting plate 7 to move in the opposite direction. The toothed groove 8 and the gear 6 drive in the opposite direction, causing the triangular car stopper 5 to flip upwards and retract, finally locking on the bottom frame of the base 1, without affecting the operation of the mine car.
[0025] After each retraction of the triangular car stopper 5, the cleaning mechanism immediately starts to clean its front end, and provides double protection through the protective box 14. The protective box 14 of the cleaning mechanism is fixed at the bottom of the base 1 corresponding to the front end of the triangular car stopper 5. On the one hand, the protective box 14 can physically shield the tip of the triangular car stopper 5, preventing accidental cuts to workers during mine car operation or worker operation, thus playing a safety protection role. On the other hand, the cleaning groove 15 inside the protective box 14 provides space for cleaning operations. After the rotating motor 20 is started, its output end drives the rotating rod 16 to rotate. The pulley 18 on the rotating rod 16 drives the other rotating rod 16 to rotate synchronously through the connecting belt 19. The brushes 17 on the outside of the two rotating rods 16 rotate accordingly, thoroughly cleaning the front end of the triangular car stopper 5 that has been retracted into the protective box 14, removing attached coal slag, mud and other impurities, ensuring that the triangular car stopper 5 can smoothly insert into the base plate the next time it stops a car. The impurities generated during cleaning fall into the dust collection box 21 at the bottom of the protective box 14 for subsequent centralized treatment.
