Description

Technical Field

[0001] This utility model relates to the field of safety protection technology, specifically to a stall safety protection device for trackless rubber-tired mining vehicles. Background Technology

[0002] In mining operations, trackless rubber-tired vehicles are widely used due to their flexible and efficient transportation capabilities. However, due to the complex and variable mining environment, these vehicles face numerous safety risks during operation.

[0003] During operation, trackless rubber-tired mining vehicles may lose speed due to braking system failure, overloading, poor road conditions, or other reasons. Once lost, the vehicle's speed becomes difficult to control, easily leading to serious accidents such as collisions and rollovers, posing a significant threat to the lives of those inside.

[0004] Mine tunnels vary in size and contain complex terrain such as curves and slopes. When a rubber-tired vehicle loses speed, traditional braking systems may not be able to stop the vehicle in a timely and effective manner, increasing the possibility of accidents.

[0005] In addition, a stall safety protection device for trackless rubber-tired mining vehicles will be developed. This device will decelerate the vehicle and protect the personnel from damage. It can not only slow down the vehicle but also improve the safety of personnel and reduce the damage to the vehicle body. Utility Model Content

[0023] Please see Figure 1 - Figure 6 This utility model provides a technical solution: a stall safety protection device for trackless rubber-tired mining vehicles, comprising:

[0024] Box shell 1;

[0025] Rotating plate 3, the inner wall of the housing 1 is rotatably connected to the side wall of rotating plate 3;

[0026] A buffer rod 31 is slidably connected to the inner wall of the rotating plate 3. A fixed rod 21 is slidably connected to the inner wall of the buffer rod 31. A dumbbell block 2 is fixedly connected to the side wall of the fixed rod 21. A pad 32 is fixedly connected to the side wall of the buffer rod 31. A buffer spring 33 is fixedly connected to the outer wall of the pad 32. One end of the buffer spring 33 is fixedly connected to the side wall of the rotating plate 3.

[0027] The inner wall of the housing 1 is slidably connected to a telescopic plate 4. The outer wall of the telescopic plate 4 is rotatably connected to the outer wall of the rotating plate 3 via a hinge 48. The side wall of the hinge 48 is fixedly connected to the outer wall of the telescopic plate 4 and the outer wall of the rotating plate 3 respectively by rivets.

[0028] A push hydraulic cylinder 41 is fixedly connected to the side wall of the telescopic plate 4 away from the hinge 48. A push hydraulic rod 42 is slidably connected to the inner wall of the push hydraulic cylinder 41. A connecting rod 44 is fixedly connected to the inner wall of the push hydraulic rod 42. A rotating block 45 is slidably connected to the side wall of the connecting rod 44. The side wall of the rotating block 45 is fixedly connected to the side wall of the rotating plate 3 away from the hinge 48. A pressure-reducing spring 43 is slidably connected to the side wall of the push hydraulic rod 42. One end of the pressure-reducing spring 43 is fixedly connected to the outer wall of the push hydraulic cylinder 41, and the other end of the pressure-reducing spring 43 is fixedly connected to the side wall of the connecting rod 44.

[0029] A base 5 is slidably connected to the inner wall of the housing 1. A fixing screw 51 is threadedly connected to the inner wall of the base 5. A telescopic hydraulic cylinder 52 is fixedly connected to the outer wall of the base 5. A telescopic hydraulic rod 54 is slidably connected to the inner wall of the telescopic hydraulic cylinder 52. One end of the telescopic hydraulic rod 54 is fixedly connected to the outer wall of the telescopic plate 4. A support spring 53 is fixedly connected to the outer wall of the base 5. One end of the support spring 53 is fixedly connected to the outer wall of the telescopic plate 4. The support spring 53 is located on the outside of the telescopic hydraulic cylinder 52.

[0030] A through block 46 is slidably connected to the outer wall of the end of the buffer rod 31 away from the fixed rod 21. The side wall of the through block 46 is fixedly connected to the side wall of the rotating plate 3. An adjusting screw 47 is threadedly connected to the inner wall of the through block 46. One end of the adjusting screw 47 is in contact with the side wall of the buffer rod 31.

[0031] Working principle:

[0032] When in use, four deep holes are made in the wall, and the fixing screw 51 connected to the base 5 through the internal thread is turned into the deep holes to fix the device. Then the housing 1 is put on. This can reduce the damage of impurities to the device, facilitate the maintenance and care of the device, and stabilize the device in a fixed state. Multiple of these devices are installed on both sides of the wall.

[0033] Simultaneously, the push hydraulic cylinder 41 fixed to the outer wall of the telescopic plate 4 is activated. The internal fluid of the push hydraulic cylinder 41 expands, and the inner wall of the push hydraulic cylinder 41 slides and connects with the side wall of the push hydraulic rod 42, causing the push hydraulic rod 42 to extend. The extension of the push hydraulic rod 42 drives the connecting rod 44 to move. The side wall of the connecting rod 44 is rotatably connected to the rotating block 45. The outer wall of the rotating block 45 is fixedly connected to the outer wall of the rotating plate 3. The movement of the connecting rod 44 drives the rotating plate 3 to move.

[0034] At the same time, the pressure relief spring 43 on the side wall of the connecting rod 44 is stretched. Since the telescopic plate 4 is rotatably connected to the rotating plate 3 through the hinge 48, and the side wall of the hinge 48 is fixedly connected to the outer wall of the telescopic plate 4 and the rotating plate 3 respectively, the rotating plate 3 rotates with the hinge 48 as the core, causing the rotating plate 3 to tilt.

[0035] When the vehicle stalls, the dumbbell block 2 of the impact device should be tightly joined together. The inner wall of the dumbbell block 2 is fixedly connected to the fixed rod 21, and the side wall of the fixed rod 21 is slidably connected to the inner wall of the buffer rod 31. This causes the dumbbell block 2 that is impacted first to rotate, which in turn causes the other dumbbell block 2 to rotate in the opposite direction. This can slow down the stalled vehicle and absorb the heat generated by the vehicle. When the vehicle force is too great, the dumbbell block 2 squeezes the buffer rod 31 through the fixed rod 21, causing the buffer rod 31 to move towards the rotating plate 3. The side wall of the buffer rod 31 is fixedly connected to the inner wall of the pad 32, which drives the pad 32 to move and compress the buffer spring 33. The elasticity of the buffer spring 33 is compressed.

[0036] At the same time, when the dumbbell block 2 presses against the rotating plate 3 and continues to move, because the rotating plate 3 is in an inclined state, the rotating plate 3 presses the connecting rod 44 through the rotating block 45. The connecting rod 44 drives the hydraulic rod 42 to move, causing the hydraulic rod 42 to move towards the inner wall of the hydraulic cylinder 41. The hydraulic cylinder 41 plays a buffering role. The connecting rod 44 pushes the decompression spring 43. When the decompression spring 43 is compressed, it will stretch due to its elasticity, which will buffer the compression at the point of collision between the stalled vehicle and the device and decelerate the vehicle.

[0037] Meanwhile, as the stalled vehicle continues to compress, the telescopic plate 4 continues to compress the telescopic hydraulic rod 54 fixedly connected to the outer wall, causing the telescopic hydraulic rod 54 to move into the telescopic hydraulic cylinder 52. The telescopic hydraulic cylinder 52 buffers the telescopic hydraulic rod 54. At the same time, the telescopic plate 4 compresses the support spring 53. The support spring 53 is affected by elasticity and pushes the telescopic plate 4 to move, continuing to buffer and decelerate the stalled vehicle.

[0038] Multiple devices are installed on both sides of the mine entrance. These devices decelerate and buffer the stalled vehicle multiple times, slowing it down and greatly improving the safety of personnel and reducing damage to the vehicle.

[0039] Meanwhile, when the mine road is wide and the vehicle is small, when it loses speed, the telescopic hydraulic cylinder 52 fixed to the outer wall of the base 5 is activated, the inner wall of the telescopic hydraulic cylinder 52 expands hydraulically, pushes the telescopic hydraulic rod 54 to extend, pushes the telescopic plate 4 to extend outward, and drives the support spring 53 fixed to the outer wall of the telescopic plate 4 to relax, so that the device extends.

[0040] When the device is used for a long time, the dumbbell blocks 2 will wear down and some gaps will appear between them. At this time, the adjusting screw 47, which is threaded to the inner wall of the through block 46, can be rotated to move the adjusting screw 47 into the through block 46. This pushes the buffer rod 31, which is slidably connected to the inner side of the through block 46, to move. This causes the fixed rod 21, which is slidably connected to the inner wall of the buffer rod 31, to move. The fixed rod 21 then moves the dumbbell blocks 2 toward the center, ensuring that the dumbbell blocks 2 continue to be in close contact, thus improving the service life of the device.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
