Technical Field

[0001] The invention relates to the technical field of coal mining equipment, in particular to a transition support vehicle of a tunnel self-moving auxiliary train. Background Art

[0002] Hydraulic self-propelled mining equipment trains are a key component of fully mechanized coal mining working faces in underground coal mines. They are primarily used to centrally arrange and move power supply, fluid supply, and control equipment, enabling rapid self-propelled movement during working face advancement and improving production efficiency. During train movement, a transition support vehicle is required to support the lines and pipelines. However, existing transition support vehicles are either top-mounted or rigidly connected, resulting in a high center of gravity or significant impact during traction, making them unstable. Therefore, improvements to the existing technology are needed. Summary of the Invention

[0004] Preferably, the telescopic frame 4 includes a connecting member hinged to each other at the head and tail; a first walking wheel 13 for walking on the track is provided at one end of the base body 1 in the walking direction, and a second walking wheel 12 for walking on the ground is provided at the other end of the base body 1 in the walking direction.

[0005] Preferably, the connecting member includes an end member 7 and a middle member 6; the end member 7 is located outside the telescopic frame 4 when retracted, and the middle member 6 is located inside the telescopic frame 4 when retracted.

[0006] Preferably, the telescopic frame 4 further includes a hinged end 5 with one end hinged to the connecting seat 3 and the other end hinged to the telescopic frame 4 .

[0007] Preferably, it further comprises: a deviation-correcting mechanism 2 provided at one end of the seat body 1 in the direction of travel, the deviation-correcting mechanism 2 being used to cooperate with a track to enable the seat body 1 to move along the track.

[0008] Preferably, the correcting mechanism 2 includes two symmetrically distributed fixing frames 21 fixed at one end of the base body 1 in the walking direction, and the two legs of the fixing frame 21 are hinged with a correcting frame 22, and the correcting frame 22 is internally provided with guide wheels 23 that abut against the inner and outer sides of the track.

[0009] Preferably, it also includes two symmetrically distributed mounting frames 24 arranged at the other end of the base body 1 in the walking direction, and the mounting frames 24 are provided with correcting wheels 25, and the correcting wheels 25 are on the inner side of the track or on the outer side of the track to abut against the track.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1 See also Figure 1-4 This embodiment provides a transition support vehicle for a tunnel self-moving auxiliary train, including a seat body 1, a connecting seat 3 fixedly arranged at at least one end of the seat body 1 in the moving direction, and a telescopic frame 4 connected to the connecting seat 3.

[0021] The present invention sets telescopic frames 4 at both ends of the transition support vehicle, which can tow the transition support vehicle at a low center of gravity position of the seat body 1, and has strong stability; and the telescopic buffering traction force prevents the impact on the center of gravity of the transition support vehicle from causing instability.

[0022] In a preferred embodiment, part of the cables can also be fixed on the telescopic frame to ensure that the cables are supported.

[0023] Preferably, the telescopic frame 4 includes a connecting member hinged at both ends; a first running wheel 13 for running on a track is provided at one end of the base body 1 in the direction of travel, and a second running wheel 12 for running on the ground is provided at the other end of the base body 1 in the direction of travel. By providing the first running wheel 13 for running on the track and the second running wheel 12 for running on the ground on the base body 1, the load-bearing portion of the transition support vehicle can be borne by the ground, reducing the load-bearing requirements of the track. At the same time, the second running wheel 12 running along the ground reduces the requirements for ground flatness and hardness.

[0024] In this way, the extension and compression of the hinged connection can buffer the traction force, reduce the impact on the base, and maintain the stability of the base.

[0025] Preferably, the connecting member includes an end member 7 and a middle member 6; the end member 7 is located outside the telescopic frame 4 when retracted, and the middle member 6 is located inside the telescopic frame 4 when retracted.

[0026] In this way, the distance between the middle pieces 6 can be compressed shorter during contraction, while preventing compression damage to the ends of the middle pieces 6.

[0027] Preferably, the telescopic frame 4 further includes a hinged end 5 hinged to the connecting seat 3 at one end and hinged to the telescopic frame 4 at the other end. In this way, the length of the hinged end 5 in the direction of travel is adjustable, which can prevent the connector from being interfered with by the components at the end of the seat body 1 during compression.

[0028] Preferably, it further comprises: a deviation-correcting mechanism 2 provided at one end of the seat body 1 in the direction of travel, the deviation-correcting mechanism 2 being used to cooperate with a track to enable the seat body 1 to move along the track.

[0029] Preferably, the deflection correction mechanism 2 includes two symmetrically distributed fixing frames 21 fixedly disposed at one end of the base 1 in the direction of travel. The fixing frames 21 have two legs hingedly connected to deflection correction frames 22. The deflection correction frames 22 are internally provided with guide wheels 23 that abut against the inner and outer sides of the track. This allows the base 1 to move stably along the track.

[0030] Preferably, the base 1 further includes two symmetrically distributed mounting brackets 24 disposed at the other end in the direction of travel of the base 1. The mounting brackets 24 are provided with corrective wheels 25, which are positioned on either the inner side or the outer side of the track to abut against the track. This allows the base 1 to move stably along the track.

[0031] Preferably, the bottom of the base body 1 is fixedly connected to a mounting tube 11, and the second running wheel 12 is arranged on the mounting tube 11 through a bearing; the bottom of the base body 1 is fixedly installed with a wheel frame 14, and the first running wheel 13 is arranged on the wheel frame 14 through a bearing.

[0032] Preferably, the base 1 further comprises a support rod 8, a frame 9 for restraining cables, and foldable bridges 10 for restraining cables, arranged on both sides of the frame 9. In this way, the foldable bridges on adjacent bases 1 are hingedly connected, and the cables can be well supported and restrained by the frame 9 and the foldable bridges 10, preventing cable wear and swinging, and making the base 1 more stable.

[0033] Preferably, the frame 9 includes vertical rails on both sides, and the foldable bridge 10 includes side frames hinged to each other at the head and tail, and a bottom plate connected to the side frames.

[0034] The specific implementation process of the present invention is as follows: when in use, the foldable bridge frames 10 of adjacent seat bodies 1 are connected, and the cables are placed in the vertical railings of the frame 9 and the side frames of the foldable bridge frames 10. The telescopic frames of the adjacent seat bodies 1 are hinged. When the traction force pulls the telescopic frame to expand or contract, the traction force slowly acts on the seat body 1 to maintain its stability; at the same time, the first walking wheel 13 runs on the track to ensure that the seat body 1 moves along the track, and the second walking wheel 12 runs on the ground to reduce the load-bearing capacity of the track, while reducing the requirements for the flatness and hardening of the ground.

[0035] At the same time, the base 1 can be guided by the deflection correction frame 22 and the deflection correction wheel 25, thereby effectively preventing the base 1 from deflecting. During the expansion and contraction process, the foldable bridge 10 folds to prevent the cable from being bent at a large angle, thereby reducing wear on the cable.

[0036] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
