Problems solved by technology

[0004] During the arch erection process, due to the mismatching direction, angle or height of the arches, it is difficult to connect the two arches, and the existing equipment is inconvenient to adjust the angle, direction and height of the arches in the tunnel. Only manually adjust the docking angle, direction and height of the two arches; therefore, a lot of manpower is required, the labor intensity is high, the operation efficiency is low and there are safety hazards

Abstract

The invention provides a lagging jack mounting arm. The lagging jack mounting arm comprises a telescopic arm rack; the rear end of the telescopic arm rack is articulated to a rotary pedestal; the rotary pedestal is arranged on a rotating device; the rotating device is used for driving the rotary pedestal to rotate; an arm rack pitching mechanism is arranged between the telescopic arm rack and therotary pedestal; the arm rack pitching mechanism is used for regulating the pitching angle of the telescopic arm rack; the front end of the telescopic arm rack is articulated with an operation basketmounting arm; the operation basket mounting arm is provided with an operation basket and an angle regulating telescopic arm; the angle regulating telescopic arm is provided with a gripper mechanism used for gripping a steel lagging jack; a leveling mechanism is arranged between the operation basket mounting arm and the telescopic arm rack; and the leveling mechanism is used for regulating the operation basket so that the operation basket is kept in a horizontal state. The lagging jack mounting arm can be used for automatically erecting a lagging jack inside a tunnel, can move the lagging jackto a specific position inside the tunnel, can also conveniently regulate the height, angle and direction of the lagging jack and the like.

Description

technical field [0001] The invention relates to the field of tunnel construction, in particular to an arch mounting arm. Background technique [0002] In recent years, my country's underground engineering has developed rapidly, and mechanized operations have gradually been widely used in engineering technology, especially in the field of underground tunnel construction. [0003] At present, in the process of tunnel construction, steel arches need to be erected on the excavated rock face. The traditional steel arches are heavy, and the installation of the arches mainly depends on manual construction; the existing steel arches are divided into multiple sections. During the erection process, The multi-segment steel arch frame needs to be lifted to the top of the tunnel by lifting equipment, and then the multi-segment steel arch frame is manually butted together, and then fixed and connected. [0004] During the arch erection process, due to the mismatching direction, angle or ...
