Description

Technical Field

[0001] The utility model relates to the technical field of a three-arm arch frame installation trolley, in particular to an arch frame position adjustment mechanism and a three-arm arch frame installation trolley. Background Art

[0002] During tunnel construction, the arch frame, along with anchor rods, steel mesh, connecting rebar, and concrete, forms a rigid body, forming a support surface to prevent collapse of the tunnel construction surface. Traditionally, arch frame installation was largely manual, requiring a large number of workers. Consequently, accidents during tunnel construction could easily pose a threat to the safety of construction workers. The use of a three-arm arch frame installation trolley can reduce the number of construction personnel to 3-4 and significantly shorten construction time.

[0003] Currently, the three-arm arch frame installation trolley is a frequently used equipment in tunnel engineering and underground engineering. Before the arch frame is installed, the three-arm arch frame installation trolley finds that there are some under-excavated locations after the blasting of the tunnel face. The crushing device is operated to complete the under-excavation processing. After that, the arch frame trolley clamps the arch frame on the ground through the arch frame clamping mechanism. After the arm mechanism is extended to the corresponding construction position, the construction workers stand in the work fence to complete the docking and installation of multiple sections of the arch frame. During the arch frame installation process, since the arch frame is a multi-section arch frame, the three-arm arch frame installation trolley is used to lift the segmented arch frame to the installation position. Then, the multiple sections of the arch frame need to be manually docked. During the docking, the docking angle, position, direction and height of the arch frame need to be manually adjusted.

[0004] Therefore, it is necessary to design an arch frame position adjustment mechanism and a three-arm arch frame installation trolley that can adjust the installation angle of the arch frame, reduce the labor intensity of workers, and reduce safety hazards. Utility Model Content
