Description

Technical Field

[0001] The utility model relates to an arch frame connecting plate positioning device with a movable handle. Background Art

[0002] With the continuous increase of infrastructure construction in my country, tunnel projects are widely used. Tunnel steel arch frames are an important load-bearing support system for tunnels. The production quality of steel arch frames directly affects the operation quality and construction safety of the project. At present, there are many common quality problems in the production of steel arch frames: for example, the deviation of the bolt holes of the connecting plates is too large, the verticality is inaccurate, etc., which leads to the misalignment of the connecting plates of the steel arch frames and the reduction of the load-bearing capacity. Therefore, how to improve the positioning accuracy of the arch frame connecting plates and improve the production efficiency of the steel arch frames are the defects and deficiencies that need to be solved urgently. To address this problem, most of the arch frame positioning auxiliary devices currently adopted are fixed type, which can only be operated in a fixed posture in a complex environment and cannot meet the requirements of multi-angle operation. Under the condition of tight schedule and heavy tasks, operating the arch frame positioning device in a fixed posture for a long time may even lead to the occurrence of occupational diseases. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide an arch frame connecting plate positioning device with a movable handle, which not only solves the common quality problems existing in the production of steel arch frames, but also effectively avoids the hidden dangers of occupational diseases caused by workers operating the steel arch frame positioning device in a fixed posture for a long time.

[0004] The purpose of the utility model is achieved as follows: it includes a base plate, two supporting bolts are connected to the base plate through bolt holes preset on the base plate, a supporting steel plate is welded to the upper part of the two supporting bolts, two front and rear vertical plates extending upward are fixed to the middle part of the top end of the supporting steel plate, a movable handle is arranged between the two vertical plates, the lower end of the movable handle is movably connected to the two vertical plates by connecting bolts, the movable handle can swing left and right after being connected to the vertical plates, a circular connecting hole is arranged at one end of the movable handle away from the connecting bolt, and the movable handle can be connected to other transmission machinery through the connecting hole; a rectangular steel plate extending upward is also welded to one side of the base plate, a pair of bolt holes are arranged on the rectangular steel plate, the bolt holes are symmetrical with the midline of the rectangular steel plate, that is, the two bolt holes are respectively arranged on the left and right sides of the midline of the rectangular steel plate, and positioning bolts are installed in the two bolt holes.

[0005] The advantages of the utility model are: using this device to process the arch frame not only effectively improves the production efficiency and solves many common quality problems in the production of steel arch frames, but also reduces the burden on the workers' wrists through the movable handle, avoiding the hidden dangers of occupational diseases caused by workers operating the steel arch frame positioning device in a fixed posture for a long time. The movable handle can achieve both automatic and manual operation, creating more possibilities for processing steel arch frames in limited space.

[0006] In addition, the device has a simple structure, can be disassembled and assembled, has a movable handle, and can be operated at multiple angles. BRIEF DESCRIPTION OF THE DRAWINGS
