Description

Technical Field

[0001] This utility model relates to the field of tunnel lining construction technology, specifically to a high-altitude and cold-climate intelligent maintenance trolley tunnel lining construction device. Background Technology

[0002] In open-cut tunnels, the reinforced concrete lining is a key load-bearing structural layer. The quality of the steel reinforcement connection in the lining directly affects the lining quality. In the current technology, the construction of open-cut tunnel lining requires the use of a trolley to provide the necessary construction platform. The existing trolley structure is relatively simple and cannot accurately match tunnel cross-sections of different sizes.

[0003] According to the patent document CN222557685U, a rebar tying trolley for open-cut tunnel lining construction is disclosed. This trolley includes a trolley frame, a rebar tying platform, a traveling mechanism, a translation mechanism, a rebar support frame, and a first lifting mechanism. The rebar tying platform is located on the left and right sides of the trolley frame, and the rebar support frame is arranged along the circumference of the tunnel on the trolley frame. The rebar tying platform includes a first tying platform and a second tying platform. In use, the first and second tying platforms are laterally extended and retracted along the tunnel on the trolley frame. This provides tying space for workers, and the rebar tying platform can also move parallel to the rebar tying trolley, avoiding repeated erection. Furthermore, the distance between the rebar tying platform and the rebar support frame can be adjusted as needed, facilitating construction. However, while this solution allows for adjustment of the distance between the support frames, it does not allow for adjustment of the platform's usable area, which is inconvenient during use.

[0004] Therefore, a high-altitude and cold-weather intelligent maintenance trolley tunnel lining construction device is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an intelligent maintenance trolley tunnel lining construction device for high-altitude and cold regions, which can solve the problem of the inability to adjust the usable area of ​​the platform.

A drive motor 17 is fixed to the side of the support base 2. A drive gear 20 is mounted on the drive motor 17. A driven gear 21 is fixed to the side of the roller 16. The driven gear 21 meshes with the drive gear 20. A pushing mechanism 12 is fixed to the top of the base 1, and one end of the pushing mechanism 12 is fixed to the bottom of the movable seat 5. Among them, the pushing mechanism 12 and the lifting mechanism 7 are both linear reciprocating electric push rods. The electric push rods use the extension and retraction characteristics of the telescopic rods to move the fixed platform 6 and the movable platform 8. When the fixed platform 6 is used alone, its height is adjusted by the pushing mechanism 12. When the fixed platform 6 and the movable platform 8 are combined, the pushing mechanism 12 and the lifting mechanism 7 can realize their synchronous up and down movement adjustment. A lifting mechanism 7 is fixed on the movable seat 5, and one end of the top of the lifting mechanism 7 is fixed to the bottom of the movable platform 8; A positioning rod 13 is welded to the side of the base 1. A movable rod 14 is movably installed inside the positioning rod 13. The top end of the movable rod 14 is movable to the bottom of the seat 5.
