[0039] Reference Figure 1~Figure 2 , which is the first embodiment of the utility model, proposes a repair machine for a height-limited tunnel, including a repair machine body 1, the repair machine body 1 has a height-limiting top 14; one end of a swing arm 2 is rotatably set on the repair machine body 1, after the swing arm 2 rotates, the swing arm 2 as a whole is always lower than the height-limiting top 14; one end of a repair claw 3 is rotatably set at the other end of the swing arm 2.

[0040] In this embodiment, in order to solve the problem that there is no repair machine suitable for use in height-restricted tunnels, a repair machine for height-restricted tunnels is designed, including a repair machine body 1, a swing arm 2 and a repair claw 3. Specifically, the height-limiting top 14 of the repair machine body 1 limits the maximum height of the entire device. One end of the swing arm 2 is flexibly rotatably set on the repair machine body 1. When the swing arm 2 is rotated, no matter at what angle it is, its overall height is always lower than the height-limiting top 14. One end of the repair claw 3 is rotatably set at the other end of the swing arm 2. For example, during a repair operation, when the tunnel needs to be repaired, the swing arm 2 rotates to lift the repair claw 3. Due to the special design of the swing arm 2, it will not exceed the height-limiting top 14, so that the repair work can be successfully completed in a height-restricted environment.

[0041] The advantage is that it can operate normally in tunnels with strict height restrictions, solving the problem that traditional repair machines cannot enter due to height restrictions. The flexible rotation design of the swing arm 2 and the repair claw 3 allows the repair machine to operate at different positions and angles, reducing the time for equipment adjustment and improving the efficiency of repair work. It avoids safety accidents caused by collision between the equipment and the top of the tunnel, ensuring the safety of operators and equipment.

[0042] Furthermore, it also includes a first telescopic member 4, both ends of which are hinged to the repair machine body 1 and the swing arm 2 respectively. After the first telescopic member 4 is extended, the swing arm 2 swings on the repair machine body 1.

[0043] In this embodiment, the two ends of the first telescopic member 4 are respectively hinged to the repair machine body 1 and the swing arm 2. When the position of the swing arm 2 needs to be adjusted, the first telescopic member 4 begins to extend. For example, when the swing arm 2 is to be lifted upward, the first telescopic member 4 extends to push the swing arm 2 to swing on the repair machine body 1, thereby accurately moving the repair claw 3 to the position to be repaired. Conversely, when the height of the swing arm 2 needs to be lowered, the first telescopic member 4 shortens to pull the swing arm 2 down.

[0044] The advantage is that the first telescopic member 4 can accurately control the swing amplitude and angle of the swing arm 2, so that the repair claw 3 can accurately reach the designated repair position, thereby improving the accuracy of the repair. The position of the swing arm 2 can be adjusted quickly and flexibly, which reduces the operation preparation time and improves the efficiency of the repair work. The posture of the swing arm 2 can be changed at any time according to different repair requirements and space limitations in the lane, so as to adapt to various complex working environments.

[0045] Furthermore, the swing arm 2 includes a first connecting arm 5, one end of which is rotatably set on the repair machine body 1, and the first connecting arm 5 is connected to the extended end of the first telescopic member 4. After the first telescopic member 4 is extended, it drives the first connecting arm 5 to swing on the repair machine body 1; one end of the third connecting arm 7 is rotatably set at the other end of the first connecting arm 5; one end of the second connecting arm 6 is rotatably set at the other end of the third connecting arm 7, and the repair claw 3 is rotatably set at the other end of the second connecting arm 6.

[0046] Furthermore, the swing arm 2 also includes a second telescopic member 8, both ends of which are hinged to the first connecting arm 5 and the third connecting arm 7 respectively. After the second telescopic member 8 is extended, the third connecting arm 7 drives the second connecting arm 6 and the repair claw 3 to swing on the first connecting arm 5.

[0047] Furthermore, the swing arm 2 also includes a third telescopic member 9, both ends of which are hinged to the second connecting arm 6 and the third connecting arm 7 respectively. After the third telescopic member 9 is extended, the second connecting arm 6 drives the repair claw 3 to swing on the third connecting arm 7.

[0048] Furthermore, the swing arm 2 also includes a fourth telescopic member 10 , both ends of which are hinged to the second connecting arm 6 and the repair claw 3 , respectively. After the fourth telescopic member 10 is extended, the repair claw 3 swings on the second connecting arm 6 .

[0049] In this embodiment, the first telescopic member 4 is extended to drive the first connecting arm 5 to swing on the repair machine body 1 to adjust the overall position. The second connecting arm 6 is connected to the first connecting arm 5 through the third connecting arm 7. When the second telescopic member 8 is extended, the third connecting arm 7 drives the second connecting arm 6 and the repair claw 3 to swing on the first connecting arm 5, changing the initial direction of the repair claw 3. Then, the third telescopic member 9 is extended to make the second connecting arm 6 drive the repair claw 3 to further swing on the third connecting arm 7, and more accurately adjust the angle of the repair claw 3. Finally, the fourth telescopic member 10 is extended to make the repair claw 3 swing again on the second connecting arm 6 to achieve accurate positioning of the repair position.

[0050] The advantage is that the combination of multiple connecting arms and multiple telescopic parts enables the swing arm 2 and the repair claw 3 to be flexibly adjusted in multiple dimensions and angles to adapt to various complex height-restricted tunnel repair scenarios. The step-by-step fine adjustment method can accurately position the repair claw 3 to the position that needs to be repaired, improving the quality and effect of the repair. The posture of the swing arm 2 and the repair claw 3 can be flexibly changed according to the differences in the shape, size and damage position of the tunnel to meet diverse repair needs. Fast and accurate positioning reduces operation time, thereby improving the work efficiency of the entire tunnel repair.

[0051] Furthermore, it also includes a crawler 11, which is rotatably arranged on the lower surface of the repairing machine body 1.

[0052] In this embodiment, a crawler 11 is installed on the lower surface of the repair machine body 1, and the crawler 11 rotates stably under power drive. For example, when the repair machine moves from one end of the lane to the other end to perform repair work, the rotation of the crawler 11 enables the repair machine to move forward or backward smoothly on the narrow and uneven lane ground without being affected too much by ground obstacles or uneven terrain. When turning, the crawlers 11 on both sides can achieve different rotation speeds, thereby flexibly changing the travel direction of the repair machine.

[0053] The advantage is that the design of the crawler 11 increases the contact area between the repair machine and the ground, improves the stability of the equipment when walking in the tunnel, and reduces the risk of tipping or slipping. It can easily cope with potholes, stones and other uneven ground in the tunnel, ensuring the normal movement and operation of the repair machine. It disperses the weight of the equipment, reduces the pressure on the bottom of the tunnel, and reduces the damage to the tunnel ground.

[0054] Furthermore, it also includes a push plate 12, one end of which is rotatably arranged on the lower surface of the repair machine body 1, and the other end of the push plate 12 is used to flatten the ground in the tunnel or to contact the ground for support when the repair machine is working.

[0055] Furthermore, it also includes a fifth telescopic member 13, both ends of which are hinged to the repair machine body 1 and the push plate 12 respectively. After the fifth telescopic member 13 is extended, the push plate 12 swings on the repair machine body 1.

[0056] In this embodiment, one end of the push plate 12 is rotatably connected to the lower surface of the repair machine body 1. When it is necessary to flatten the ground in the tunnel, the fifth telescopic member 13 extends to push the push plate 12 to swing, so that the other end of the push plate 12 contacts the ground and performs the flattening operation. For example, when there are protruding stones or deposits on the ground in the tunnel, the fifth telescopic member 13 extends, and the push plate 12 flattens them, creating good ground conditions for the movement and operation of the repair machine. When the repair machine performs repair work, the fifth telescopic member 13 extends to make the push plate 12 contact the ground, play a supporting role, and increase the stability of the repair machine.

[0057] The advantage is that the push plate 12 can effectively flatten the uneven ground in the tunnel, provide a stable foundation for the movement and operation of the repair machine, and improve the safety and efficiency of the work. It provides additional support during the repair work, reduces the shaking and instability of the repair machine, and ensures the accuracy and quality of the repair work. The contact between the push plate 12 and the ground increases the contact area between the repair machine and the ground, further improving the stability of the equipment during operation.
