Embodiment Construction

[0028] see Figure 1-7 , In this embodiment, the frame 12 is a frame that can rotate and move vertically, and is installed on the rotary mechanism served by the rotary support device 11 of the worm and worm gear. Worm screw and worm gear rotary supporting device 11 is installed on the longitudinal movement mechanism that is made of longitudinal movement support 5, track bolster 3, shaped steel track 4, road wheel 6 and longitudinal movement motor 7. 10 among the figure is the rotary motor of the worm gear rotary support device 11. The worm wheel and worm gear rotary support device and the longitudinal movement mechanism all continue to use the prior art structure. The telescopic arm is hinged to the telescopic arm outer frame 14 on the machine base 12 by the hinge shaft 31 at its tail, the telescopic hydraulic cylinder 9 with a pressure maintaining circuit set in the telescopic arm outer frame 14 and the piston installed in the telescopic hydraulic cylinder 9 The telescopic ...

Abstract

The invention relates to a lining steel arch frame installing groove grooving machine for treating existing railway tunnel defects, and belongs to the technical field of railway tunnel defect treatment equipment. The lining steel arch frame installing groove grooving machine consists of a machine seat, a telescopic arm and a cutting head, wherein the telescopic arm is arranged on the machine seat and is provided with a pitch hydraulic cylinder, and the cutting head is arranged at the front end of the telescopic arm and can swing relative to the telescopic arm. The lining steel arch frame installing groove grooving machine has the advantages that the fully mechanical grooving operation of railway tunnel lining steel arch frame installing grooves can be realized, in addition, contact nets and load bearing cables of the existing railway tunnel can be safely avoided, the grooving efficiency is high, and the safety is high. Through a defect treatment trolley, the grooving machine can complete the grooving operation of a plurality of steel arch frame installing grooves in one trolley station.

Description

technical field [0001] The invention relates to construction equipment for tunnel disease regulation. In particular, the invention relates to a lining steel arch installation groove slotting device for disease control of existing railway tunnels. Background technique [0002] In the repair of existing railway tunnels, it is necessary to slot the lining to inlay steel arches to reinforce the cracked lining. The current common practice is to use manual hand-held general-purpose slotting equipment for slotting operations, which has a low degree of mechanization, high labor intensity, and low efficiency. Especially in the vault slotting operation, due to the influence of catenary and catenary cables, the construction is more difficult, and workers face the danger of concrete blocks falling and being injured at any time, and construction safety is difficult to guarantee. In the existing railway tunnel disease control, in order to ensure the normal operation of the train, the di...
