Description

Technical Field

[0001] The invention relates to the technical field of mining, and in particular to a tire replacement and maintenance service vehicle for underground mining equipment. Background Art

[0002] Mining, a comprehensive energy term, is the technology and science of exploiting mineral resources from the earth's crust and surface. Mining in a broad sense also includes the mining of coal and oil. The mining industry is an important raw material industry. Metal ores are the main raw materials for the smelting industry, and non-metallic ores are important chemical raw materials and building materials.

[0003] During long-term use, mining equipment is prone to tire damage due to its service life. Cranes are usually used for lifting and transportation, but cranes are usually difficult to enter the narrow interior of mines, so specific maintenance service vehicles are required for transportation and maintenance.

[0004] There is a prior art, for example, Chinese invention patent application CN117360362A discloses a tire replacement and maintenance service vehicle for underground mining equipment, which relates to the field of tire replacement and maintenance technology, including a replacement and maintenance vehicle and an underground mining vehicle. An underground mining vehicle is placed on top of the replacement and maintenance vehicle. The maintenance service vehicle designed by the invention reduces the time required for maintenance of the underground mining vehicle and the transportation cost of the underground mining vehicle.

[0005] However, the above patent still has certain shortcomings. When the tire of the mine car is damaged, the mine car needs to be pushed to the top of the service vehicle. It can be seen from the above patent that by starting the hydraulic cylinder, the push-up plate can be raised to the bottom end of the axle. Only the bottom end of the axle is lifted. When repairing and replacing the metal wheel hub of the mine car, it is necessary to tighten the bolts between the metal wheel hub and the mine car. The contact area between the push-up plate and the axle is relatively limited, and it is difficult to maintain the original static state of the axle. It is very easy to cause the axle to rotate by itself, which will increase the difficulty of replacing the metal wheel hub. The operator needs to spend more time and energy to ensure the stability and safety of the axle.

[0039] like Figures 1 to 8 As shown, according to one aspect of the present invention, there is provided an underground mining equipment tire replacement and maintenance service vehicle, comprising a vehicle seat body 1, a driving assembly 2 is arranged above the vehicle seat body 1, and an anti-slip limit assembly 3 located on one side of the driving assembly 2 is arranged on the vehicle seat body 1;

[0040] A mine car body 13 is arranged at the top of the seat body 1, an axle body 132 is rotatably arranged at the bottom of the mine car body 13, and two guardrails 12 are fixedly arranged on both sides of the mine car body 13 at the top of the seat body 1;

[0041] The driving assembly 2 includes a hydraulic cylinder 21 located on one side of the mining vehicle body 13, and a fixing rod 23 fixedly connected to the guardrail 12 is fixedly arranged at the top of the hydraulic cylinder 21, and a pushing rod 22 is fixedly arranged at the output end of the hydraulic cylinder 21;

[0042] The anti-slip limit assembly 3 includes a connecting rod 311 fixedly connected to one side of the pushing rod 22, a lifting seat 31 is fixedly arranged on the side of the connecting rod 311 away from the pushing rod 22, and the lifting seat 31 is slidably connected to the top of the seat body 1, and the lifting seat 31 is located below the mining car body 13, and the lifting seat 31 is "U"-shaped, two square rods 332 are slidably arranged on the inner wall of one side of the lifting seat 31, and two guide rods 331 are slidably arranged on the inner wall of the other side of the lifting seat 31, and the two guide rods 331 are extended to the outside of the lifting seat 31, and a clamping block 33 is fixedly arranged between each guide rod 331 and each square rod 332, two oblique sliding rods 32 are fixedly arranged on the top of the seat body 1, and the two oblique sliding rods 32 are slidably connected to the two guide rods 331 respectively, and the two clamping blocks 33 are fixedly arranged with elastic clips 34, and the elastic clips 34 are used to engage with the outer wall of the axle body 132.

[0043] The two guardrails 12 are vertically symmetrically arranged with respect to the seat body 1 , the pushing rod 22 is slidably connected to the top of the seat body 1 , and a movable groove matching the pushing rod 22 is provided at the top of the seat body 1 .

[0044] A square slide groove 333 matching the square rod 332 is provided on the inner wall of the lifting seat 31 close to the square rod 332, a through groove matching the guide rod 331 is provided on the inner wall of the lifting seat 31 close to the guide rod 331, and an inclined slide groove matching the guide rod 331 is provided on the side of the inclined slide rod 32 close to the guide rod 331.

[0045] The two elastic clips 34 are symmetrically arranged about the vertical center line of the lifting seat 31 . A rubber layer 341 is fixedly arranged on the inner wall of the elastic clip 34 , and the rubber layer 341 is used to be in close contact with the outer wall of the axle body 132 . Two metal hubs 131 are fixedly arranged at both ends of the axle body 132 .

[0046] When the mining car body 13 moves to the top of the lifting seat 31, the hydraulic cylinder 21 can be started to drive the pushing rod 22 to rise and slide inside the movable groove. The sliding of the pushing rod 22 can drive the lifting seat 31 fixedly connected to the connecting rod 311 to rise, and while the lifting seat 31 slides, the two guide rods 331 can slide along one side of the two inclined sliding rods 32 respectively, and the square rods 332 fixed on the other side of the two clamping blocks 33 can slide inside the square sliding groove 333, so that the two clamping blocks 33 can slide left and right and gradually move away from each other. When the two elastic clips 34 contact the two axle bodies 132 at the same time, the elastic clips 34 can be deformed. When the lifting seat 31 slides to the highest position, the two elastic clips 34 can be clamped with the two axle bodies 132 respectively, and the rubber layer 341 inside the elastic clip 34 can be tightly attached to the outer wall of the axle body 132, which can play an anti-skid role, and is convenient for the subsequent maintenance process to remove the metal hubs 131 at both ends of the axle body 132.

[0047] In this embodiment, two guide rail assemblies 4 are respectively provided on both sides of the seat body 1, and the guide rail assemblies 4 include two guide rail plates 42 rotatably connected to the two sides of the seat body 1, two slide groove rods 41 are fixedly provided on both sides of the pushing rod 22, and two sliders 43 are fixedly provided on one side of the two guide rail plates 42 close to the slide groove rod 41, and the outer walls of the two slide groove rods 41 are provided with straight slide grooves matching the sliders 43.

[0048] The guide rail assembly 4 further includes two pairs of baffles 45 fixed to the top of the seat body 1 , and the two pairs of baffles 45 are respectively located on both sides of the two guardrails 12 , and a pair of guide rails 44 are fixedly disposed at the top of the two guide rail plates 42 .

[0049] When the damaged mine car body 13 is to be transported, the mine car body 13 can be pushed to the side of the guide plate 42 set on the side of the seat body 1. At this time, by starting the hydraulic cylinder 21, the hydraulic rod set at its output end slides downward, and then drives the pushing rod 22 fixedly connected to the bottom end of the hydraulic rod to slide downward, and at the same time drives the two slide rods 41 to slide downward. Since the two sliders 43 fixed on one side of the two guide plates 42 slide on the side of the two slide rods 41 respectively, the two guide plates 42 surround the connection position with the seat body 1. The two pairs of baffles 45 are respectively separated from the top ends of the two guide rail plates 42. When the bottom ends of the guide rail plates 42 are in contact with the ground, the mine car body 13 can be pushed to move along the guide rail bar 44 to the top of the car seat body 1. When the mine car body 13 is located above the lifting seat 31, the hydraulic cylinder 21 can be started to drive the hydraulic rod to reset and drive the pushing rod 22 to slide upward along the movable groove. At the same time, with the cooperation of the guide rail assembly 4, the two guide rail plates 42 can be rotated to the position in contact with the baffle 45, which can play a protective role.

[0050] In this embodiment, an anti-skid component 5 is arranged under the seat body 1, and the anti-skid component 5 includes two connecting rods 51 respectively fixed at the bottom ends of the two slide groove rods 41, and two telescopic sleeves 52 are fixedly arranged at the bottom ends of the two connecting rods 51. Two telescopic seats 53 are slidably arranged on the inner walls of the two telescopic sleeves 52. A return spring is fixedly arranged between the top of each telescopic seat 53 and the inner wall of each telescopic sleeve 52, and a wear-resistant plate 54 is fixedly arranged at the bottom ends of the two telescopic seats 53.

[0051] Two sets of transfer wheels 11 are rotatably provided at the bottom end of the seat body 1 .

[0052] When the damaged mine car body 13 is to be transported, the mine car body 13 can be pushed to the side of the guide plate 42 set on one side of the seat body 1. At this time, by starting the hydraulic cylinder 21, the pushing rod 22 fixedly connected to its bottom end is lowered, and the sliding of the pushing rod 22 can drive the connecting rod 51 fixedly connected to its bottom end to slide, and then drive the telescopic sleeve 52 fixedly connected to the bottom end of the connecting rod 51 to slide downward, and at the same time drive the telescopic seat 53 fixedly connected to the inside by the return spring to move downward, and drive the wear-resistant plate 54 to move downward. When the bottom end of the guide plate 42 contacts the ground, the wear-resistant plate 54 contacts the ground at this time, and the telescopic seat 53 is squeezed and slides into the telescopic sleeve 52, squeezing the return spring at the same time. The telescopic seat 53 is squeezed by the elastic force of the return spring and makes the wear-resistant plate 54 close to the ground, which plays a role in improving the stability of the seat body 1.

[0053] The working principle of the device is as follows: when the damaged mine car body 13 is transported, the mine car body 13 can be pushed to the side of the guide plate 42 set on the side of the car seat body 1. At this time, by starting the hydraulic cylinder 21, the pushing rod 22 fixedly connected to its output end is lowered and slides inside the movable groove, and at the same time, the two slide rods 41 are driven to descend. Since the two sliders 43 fixed on one side of the two guide plates 42 slide on the two sides of the two slide rods 41 respectively, the two guide plates 42 rotate around the connection position with the car seat body 1, and the two pairs of baffles 45 are respectively connected to the two guide rails. The top of the plate 42 is separated. At the same time, the sliding of the pushing rod 22 can drive the connecting rod 51 fixedly connected to its bottom end to slide, and then drive the telescopic sleeve 52 fixedly connected to the bottom end of the connecting rod 51 to descend and slide inside the vehicle seat body 1, and at the same time drive the telescopic seat 53 fixedly connected to the inside through the return spring to descend, and drive the wear-resistant plate 54 to descend. When the bottom end of the guide plate 42 contacts the ground, the wear-resistant plate 54 contacts the ground at this time, and the telescopic seat 53 is squeezed and slides into the telescopic sleeve 52, and at the same time squeezes the return spring, and the telescopic seat 53 is affected by the elastic force of the return spring. The wear-resistant plate 54 is squeezed and made to be close to the ground. The mine car body 13 can be pushed to move along the guide rail 44 to the top of the car seat body 1. When the mine car body 13 moves to the top of the lifting seat 31, the hydraulic cylinder 21 can be started to drive the hydraulic rod to move from bottom to top, and drive the pushing rod 22 to rise. The sliding of the pushing rod 22 can drive the lifting seat 31 fixedly connected to the connecting rod 311 to rise. When the lifting seat 31 slides, the two guide rods 331 can slide along one side of the two inclined sliding rods 32 respectively, and at the same time, the square rods 33 fixed on the other side of the two clamping blocks 33 respectively 2 can slide inside the square slide groove 333, so that the two clamping blocks 33 can slide left and right and gradually move away from each other. When the two elastic clips 34 are in contact with the two axle bodies 132 at the same time, the elastic clips 34 can be deformed. When the lifting seat 31 slides to the highest position, the two elastic clips 34 can be clamped with the two axle bodies 132 respectively, and the rubber layer 341 inside the elastic clip 34 can be tightly attached to the outer wall of the axle body 132, which can play an anti-slip role, and it is convenient to disassemble the metal hubs 131 at both ends of the axle body 132 during subsequent maintenance.
