Technical Field
[0001] This utility model belongs to the field of mining car transportation technology, and in particular relates to an anti-tipping unloading device for mining car transportation. Background Technology
[0002] Coal mine underground operations are complex and pose high safety risks. As a crucial link in coal transportation, the safety of mine cars directly affects the safe production of coal mines. Currently, during underground operations, mine cars typically travel on narrow tracks in complex environments. When mine cars are unevenly loaded or travel at excessive speeds, they are prone to tipping over. Tipping over can cause safety accidents, reduce work efficiency, and cause materials inside the car bucket to spill out, resulting in resource waste. Therefore, a tipping over unloading device for mine car transportation is proposed. Utility Model Content
[0003] The purpose of this invention is to provide an anti-tipping unloading device for mine car transportation. Specifically, during unloading, when the center of gravity of the transport car bucket moves to the left, the starting motor drives two moving blocks to the right via a threaded rod. The movement of these moving blocks causes a counterweight to move to the right, thus creating a mutual force with the center of gravity of the transport car bucket, preventing tipping during unloading. This solves the problem that in current coal mine operations, mine cars typically travel on narrow tracks in complex environments, and when the load is uneven or the speed is too high, tipping accidents are prone to occur. Tipping accidents cause safety hazards, reduce work efficiency, and cause material spillage from the bucket, resulting in resource waste.
[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0005] This utility model relates to an anti-tipping unloading device for mine car transportation, comprising a main frame mechanism, the main frame mechanism including a transport car body, an anti-tipping component installed inside the transport car body, an auxiliary component installed on the top of the transport car body, the auxiliary component including a buckle plate, the anti-tipping component including a motor, a cavity opened inside the transport car body, a threaded rod rotatably connected inside the transport car body, a counterweight block installed inside the cavity, the right output end of the motor being fixedly connected to the left side of the threaded rod via a coupling, and movable blocks being fixedly connected to the left and right sides of the top of the counterweight block. The two movable blocks are threadedly connected to the outer surface of the threaded rod on the side away from the counterweight block. The outer wall of the counterweight block contacts the inner wall of the cavity. A rack is fixedly connected to the top of the two movable blocks. A hydraulic rod is rotatably connected to the top right side of the transport vehicle body via a pin. When unloading, the center of gravity of the transport vehicle bucket moves to the left, and the starter motor drives the two movable blocks to move to the right through the forward rotation of the threaded rod. When the movable blocks move, they will drive the counterweight block to move to the right, thus forming a mutual force with the center of gravity of the transport vehicle bucket body, avoiding the side tipping during unloading and reducing the occurrence of safety accidents.
[0006] Furthermore, a transport vehicle body is provided on the top of the transport vehicle body, and a hinge block is fixedly connected to the bottom left side of the transport vehicle body. The hinge block is rotatably connected to the top left side of the transport vehicle body via a pin. A sliding groove is provided on the bottom of the transport vehicle body, and a slider is slidably connected inside the sliding groove. The slider is rotatably connected to the side of the hydraulic rod away from the transport vehicle body via a pin. Limit grooves are provided on the front and back slopes of the transport vehicle body. When unloading is required, the hydraulic rod is first activated to drive the slider to move. When the slider moves, it slides inside the sliding groove. At the same time, it is rotatably connected to the transport vehicle body via the hinge block on the bottom left side of the transport vehicle body. Therefore, when the hydraulic rod pushes the slider to slide inside the sliding groove, the transport vehicle body will rotate to the left, at which time the material inside the transport vehicle body can be discharged.
[0007] Furthermore, openings are provided on both the front and back of the top of the transport vehicle body. A gear is meshed with the top of the rack, and a bidirectional threaded rod is fixedly connected inside the gear. The front and back of the outer surface of the bidirectional threaded rod are rotatably connected to the front and back of the interior of the transport vehicle body. When unloading is completed, the threaded rod drives the moving block to move to the left, at which time the rack will drive the bidirectional threaded rod to rotate in the opposite direction through the gear.
[0008] Furthermore, both the front and back sides of the outer surface of the bidirectional threaded rod are threaded with connecting blocks. The outer walls of both connecting blocks are in contact with the inner wall of the opening. Both connecting blocks penetrate the opening and extend to the top of the transport vehicle body. The tops of both connecting blocks are fixedly connected to the bottom of the buckle plate. The corresponding sides of the two buckles are in contact with the inner wall of the limiting groove. When the bidirectional threaded rod rotates, it will drive the two connecting blocks to move closer to each other. At the same time, the two connecting blocks will slide inside the opening. The opening provides a certain degree of limitation for the movement trajectory of the connecting blocks. When the two connecting blocks move closer to each other, they will drive the two buckles to move closer to each other. At this time, the hydraulic rod will drive the transport vehicle body to reset. At the same time as the transport vehicle body resets, the two buckles will be embedded in the limiting groove. At this time, the two buckles will limit and fix the transport vehicle body through the function of the limiting groove.
[0009] This utility model has the following beneficial effects:
[0010] 1. This utility model incorporates an anti-tipping component. Specifically, during unloading, when the center of gravity of the transport vehicle's bucket moves to the left, the starting motor drives two moving blocks to the right via a threaded rod. The movement of these moving blocks causes the counterweight to move to the right, thus creating a mutual force with the center of gravity of the transport vehicle's bucket. This prevents tipping during unloading, reduces the occurrence of safety accidents, significantly improves work efficiency, and greatly reduces resource waste.
[0011] 2. This utility model incorporates an auxiliary component. Specifically, when the transport truck body is unloaded and reset, the reverse rotation of the threaded rod drives the gear to rotate via the rack. As the gear rotates, it drives the two connecting blocks closer together via the bidirectional threaded rod. When the two connecting blocks are close together, they drive the two buckle plates to close together. Simultaneously with the reset of the transport truck body, the two buckle plates are embedded in the limiting groove. At this time, the two buckle plates, through the limiting groove, limit and fix the transport truck body, reducing the possibility of the transport truck body tipping over during movement or loading, and further improving the practical effect of the equipment.
[0012] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0021] Please see Figures 1-5 As shown, this utility model is an anti-tipping unloading device for mine car transportation, including a main frame mechanism 1, which includes a transport car body 111. An anti-tipping component 2 is installed inside the transport car body 111, and an auxiliary component 3 is installed on the top of the transport car body 111. The auxiliary component 3 includes a buckle plate 311. The anti-tipping component 2 includes a motor 211. A cavity is opened inside the transport car body 111, and a threaded rod 212 is rotatably connected inside the transport car body 111. A counterweight 214 is installed inside the cavity. The right output end of the motor 211 is fixedly connected to the left side of the threaded rod 212 via a coupling. The left and right sides of the top of the counterweight 214 are... The two movable blocks 213 are fixedly connected. The side of the two movable blocks 213 away from the counterweight block 214 is threadedly connected to the outer surface of the threaded rod 212. When the center of gravity of the transport vehicle body 114 moves to the left during unloading, the starting motor 211 drives the two movable blocks 213 to move to the right through the forward rotation of the threaded rod 212. When the movable blocks 213 move, they will drive the counterweight block 214 to move to the right, thus forming a mutual force with the center of gravity of the transport vehicle body 114. This prevents the vehicle from tipping over during unloading, reduces the occurrence of safety accidents, and at the same time, reducing the probability of tipping over will greatly improve work efficiency and significantly reduce the waste of resources.
[0022] The outer wall of the counterweight 214 contacts the inner wall of the cavity, and the top of the two moving blocks 213 is fixedly connected to the rack 215. The top right side of the transport vehicle body 111 is rotatably connected to the hydraulic rod 112 via a pin.
[0023] The top of the transport vehicle body 111 is provided with a transport vehicle bucket body 114. A hinge block 116 is fixedly connected to the bottom left side of the transport vehicle bucket body 114. The hinge block 116 is rotatably connected to the top left side of the transport vehicle body 111 via a pin. A slide groove 115 is provided at the bottom of the transport vehicle body 111. A slider 113 is slidably connected inside the slide groove 115. The slider 113 is rotatably connected to the side of the hydraulic rod 112 away from the transport vehicle body 111 via a pin. Limiting grooves 312 are provided on the front and back slopes of the transport vehicle bucket body 114.
[0024] The transport vehicle body 111 has openings 313 on both the front and back of its top. A gear 314 is meshed with the top of the rack 215. A bidirectional threaded rod 315 is fixedly connected inside the gear 314. The front and back of the outer surface of the bidirectional threaded rod 315 are rotatably connected to the front and back of the interior of the transport vehicle body 111. Connecting blocks 316 are threadedly connected to the front and back of the outer surface of the bidirectional threaded rod 315. The outer walls of the two connecting blocks 316 are in contact with the inner walls of the openings 313. The two connecting blocks 316 penetrate the openings 313 and extend to the top of the transport vehicle body 111. The tops of the two connecting blocks 316 are fixedly connected to the bottom of the buckle plate 311. The corresponding sides of the two buckle plates 311 are connected to the limiting grooves. When the inner wall of the transport truck body 114 is in contact with the material and the unloading is completed, the threaded rod 212 reverses and drives the gear 314 to rotate through the rack 215. When the gear 314 rotates, it drives the two connecting blocks 316 to move closer to each other through the bidirectional threaded rod 315. When the two connecting blocks 316 move closer to each other, they drive the two buckle plates 311 to move closer to each other. At the same time as the transport truck body 114 is reset, the two buckle plates 311 will be embedded in the limiting groove 312. At this time, the two buckle plates 311 will limit and fix the transport truck body 114 through the limiting groove 312, reducing the possibility of the transport truck body 114 tipping over when moving or loading, and further improving the practical effect of the equipment.
[0025] A specific application of this embodiment is as follows: During use, when unloading is required, the hydraulic rod 112 is first activated to drive the slider 113 to move. The slider 113 slides inside the chute 115. Simultaneously, it is rotatably connected to the transport vehicle body 111 via a hinge block 116 on the left side of the bottom of the transport vehicle body 114. Therefore, when the hydraulic rod 112 pushes the slider 113 to slide inside the chute 115, the transport vehicle body 114 will rotate to the left. At this time, the material inside the transport vehicle body 114 can be discharged, and unloading is completed. When material is being unloaded, motor 211 needs to be started. Motor 211 drives threaded rod 212 to rotate forward. The rotation of threaded rod 212 causes two moving blocks 213 to move to the right. The movement of moving blocks 213 causes the counterweight block 214 to move as well. When the transport vehicle body 114 unloads material, its center of gravity shifts to the left, causing the counterweight block 214 to move to the right. This creates a mutual force, preventing tipping during unloading and reducing the likelihood of accidents. This will significantly improve work efficiency and greatly reduce resource waste. When the two moving blocks 213 move to the right, the rack 215 will cause the two latch plates 311 to move away from each other. After unloading is completed, when the threaded rod 212 drives the moving blocks 213 to move to the left, the rack 215 will drive the bidirectional threaded rod 315 to rotate in the opposite direction through the gear 314. When the bidirectional threaded rod 315 rotates, it will cause the two connecting blocks 316 to move closer to each other. At the same time, the two connecting blocks 316 will slide inside the opening 313, which is a connecting... The movement trajectory of block 316 provides a certain degree of limitation. When two connecting blocks 316 approach each other, they will cause the two buckle plates 311 to approach each other. At this time, the hydraulic rod 112 will drive the transport truck body 114 to reset. While the transport truck body 114 is resetting, the two buckle plates 311 will be embedded in the limiting groove 312. At this time, the two buckle plates 311 will limit and fix the transport truck body 114 through the limiting groove 312, reducing the possibility of the transport truck body 114 tipping over when moving or loading, and further improving the practical effect of the equipment.
