Finally, the bolt I 204 is inserted into the adjustment slot 203 to fix and limit between the fixed plate 202 and the movable plate 205, and further fix and limit between the bottom plate 101 and the connecting rod 106. Similarly, multiple groups of connecting rods 106 are also fixed in sequence, so as to fix the climbing frame composed of the bottom plate 101 and multiple groups of connecting rods 106, enabling the staff to move up and down along the support rods 107 between the connecting rods 106 in sequence, so as to overhaul and maintain the tunnel inner wall, and further increasing the application range of the device; after use, the staff can remove the fixing unit 200 in sequence, so that multiple groups of connecting rods 106 are folded on the bottom plate 101 in sequence. Then, the staff can push the bottom plate 101 to move and recycle it, preventing the device from shaking and being inconvenient for the staff to move, and further increasing the use comfort of the staff.

[0032] Embodiment 2

[0033] Referring to Figure 1 - Figure 5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that a limiting unit 300 is provided on the connecting rod 106. The limiting unit 300 includes a connecting component 301 provided on the connecting rod 106, a movable sleeve II 302 provided on the connecting component 301, a fixed screw II 303 provided at one end of the movable sleeve II 302, an adjusting plate 304 provided at one end of the fixed screw II 303, and a bolt II 305 provided on the adjusting plate 304. By moving the adjusting plate 304 up and down and rotating the movable sleeve II 302 on the fixed screw II 303, the top of the adjusting plate 304 can be closely attached to the tunnel top, thereby preventing the device from shaking or shifting during use, and further increasing the use stability of the device.

[0034] Compared with Embodiment 1, further, a toothed plate 306 is provided on the top of the adjusting plate 304, which increases the friction between it and the tunnel top, makes the fit closer, and further prevents the device from shaking or shifting during use.

[0035] During use, according to the size of the culvert tunnel, after the staff assembles a climbing frame of an appropriate size, there will be a certain distance between the connecting rod 106 at the top of the climbing frame and the tunnel top at this time. First, rotate and install the connecting component 301 on the connecting rod 106, then take out the second bolt 305, move the adjusting plate 304 upward until the toothed plate 306 at the top of the adjusting plate 304 fits against the tunnel top. At this time, control the movable sleeve two 302 to rotate on the outside of the fixed screw two 303 so that the second bolt 305 can be inserted into the adjusting plate 304 to fix it. Then continue to control the movable sleeve two 302 to rotate on the outside of the fixed screw two 303 so that the toothed plate 306 at the top of the adjusting plate 304 fits tightly against the tunnel top, thereby limiting and fixing the connecting rod 106 at one end of the connecting component 301, preventing the climbing frame assembled by the staff from shaking or shifting during construction, thus increasing the use stability of the device, and at the same time facilitating the staff to carry out construction and maintenance above it, increasing the use comfort and use safety of the staff.

[0036] The rest of the structure is the same as that of Embodiment 1.

By installing multiple groups of protection units 400 on the support rod 107, the staff can briefly lean on and rest when they are exhausted, thereby increasing the use comfort and use safety of the staff.

[0039] Compared with Embodiment 2, further, the sliding plate 401 is provided with a fixing bolt 402. The sliding plate 401 is fixed on the support rod 107 through the fixing bolt 402, so that the staff can arbitrarily install an appropriate amount of protection units 400 according to the distance between multiple support rods 107 between the connecting rods 106, and then support and rest the staff during the crawling process, thereby increasing the use comfort and use safety of the staff.

[0040] During use, since the staff need to move and perform maintenance on it for a long time, the physical strength is great. At this time, according to the stature of the staff, the two sets of sliding plates 401 are respectively installed on both sides of the support rod 107, and the distance between the two sets of sliding plates 401 is adapted to the stature of the staff, so that staff of different statures can rely on it to rest, thereby increasing the comfort of use for the staff; then it is fixed and limited by the fixing bolt 402, and then the adjusting bearing 404 is rotated to adjust the connecting plate two 405 at one end to rotate inward or outward according to the distance between the two sets of sliding plates 401, so as to support the back of the staff during the crawling movement of the staff, enabling the staff to take a short rest above it and preventing the staff from falling due to exhaustion, thus increasing the safety of use for the staff.

[0041] The rest of the structure is the same as that of Embodiment 2.
