Problems solved by technology
The structure of the existing trolley is simple, and its function is only a movable scaffold. The steel bar binding is mainly to manually send the steel bars on the ground from the side of the trolley to the arch, and use welding or threaded sockets to carry out butt extension of the steel bars, and finally Utilize the elasticity of the steel bar to form a ring on the outside of the trolley
This binding method has problems such as slow speed, difficult quality control, and large labor input.

The invention belongs to the technical field of shield tunnel construction, and relates to precise assembly complete equipment for mountain tunnel secondary lining steel bars. The precise assembly complete equipment comprises a walking assembly, a front portal frame, a rear portal frame and a secondary lining steel bar mounting assembly, wherein the front portal frame and the rear portal frame are mounted on the walking assembly, and the secondary lining steel bar mounting assembly is mounted between the front portal frame and the rear portal frame; the secondary lining steel bar mounting assembly comprises a connecting beam and a first rotating drive, wherein the connecting beam is mounted between the front portal frame and the rear portal frame, and the first rotating drive is mounted on the front portal frame and the rear portal frame and used for driving the connecting beam to rotate around the axis of the connecting beam; a fixing part of a second rotating drive is fixedly mounted on the connecting beam, and a telescopic arm is mounted on a rotating part of the second rotating drive; a taking and placing assembly used for taking and placing the steel bars is mounted at one end of the telescopic arm; and a steel bar mesh is grabbed through the taking and placing assembly, the first rotating drive drives the connecting beam to rotate around the axis of the connecting beam, the telescopic arm rotates around the tunnel axis or the axis parallel to the tunnel axis, the second drive drives the first telescopic arm to rotate to adjust the posture of the steel bar mesh, and positioning and mounting of the steel bar mesh are achieved.
Description
technical field [0001] The invention belongs to the technical field of shield tunnel construction, and in particular relates to a precise assembly equipment for second-lined steel bars of mountain tunnels. Background technique [0002] The secondary lining reinforcement is an important part of the secondary lining support of mountain tunnels, and its binding work is an indispensable and important process in the construction of mountain tunnels. At present, the binding of steel bars for the second lining is generally carried out manually on-site with the help of steel bar benches. The structure of the existing trolley is simple, and its function is only a movable scaffold. The steel bar binding is mainly to manually send the steel bars on the ground from the side of the trolley to the arch, and use welding or threaded sockets to carry out butt extension of the steel bars, and finally Utilize the elasticity of the steel bar to form a ring on the outside of the trolley. This ...
