Embodiment Construction

[0018] The present invention will be further described below in conjunction with accompanying drawing.

[0019] Such as Figure 1-3 As shown, a fully automatic tunnel circumferential cutting device of the present invention includes a vehicle running device 1, a sliding track 4, a sliding mechanism 9, a rotary device 10, a mechanical arm device, a rotary arm 16, a hydraulic wall saw 18 and a numerically controlled hydraulic system 7.

[0020] The automobile running device 1 comprises a car body 6, a driver's cab 2, a silent generator set 3, two water tanks and four hydraulic supporting legs 8. The upper rear of the car body 6 is provided with a sliding track 4, which can slide and change its position for the sliding mechanism 9. Two water tanks are arranged on both sides of the sliding track 4 and the upper middle of the car body 6, and are connected with the water cooling system 17, and are self-supplied. The driver's cab 2 is located at the front of the car body 6 , and th...

Abstract

The invention discloses full-automatic tunnel circumferential cutting equipment and belongs to the technical field of engineering machines. The full-automatic tunnel circumferential cutting equipmentmainly solves the problems that when explosions or a mechanical air pick or tunnel circumferential cutting equipment is adopted for breaking down lining concrete cracks, the efficiency is low, and thesecurity risk is high. The full-automatic tunnel circumferential cutting equipment is mainly characterized by comprising a car walking device, a sliding track, a sliding mechanism, a rotary device, amechanical arm device, a rotary arm, a hydraulic wall saw and a numerical control hydraulic system; the sliding mechanism is mounted on the sliding track on the car walking device; the mechanical armdevice is at least of a three-link arm structure capable of stretching out and drawing back, the lower end of the mechanical arm device is connected with the sliding mechanism through the rotary device, and the upper end of the mechanical arm device is connected with the rotary arm; and the rotary arm is connected with the hydraulic wall saw. The full-automatic tunnel circumferential cutting equipment has the advantages of being high in automation degree and easy to operate and remarkably improving the construction efficiency, and is mainly used for fast breaking down existing diseased tunnellining concrete.

Description

technical field [0001] The invention belongs to the technical field of construction machinery, and in particular relates to a tunnel circumferential cutting device for fully automatic demolition of existing line disease tunnel lining concrete. Background technique [0002] During the pouring process, the secondary lining concrete of the tunnel construction is often affected by various reasons and diseases. The cracking of the lining concrete is the most typical problem, which needs to be removed and repaired in time. The current common method is to use blasting, mechanical pneumatic picks or tunnel circumcision equipment to destroy, but the efficiency is low and the safety risk is great. The circular automatic cutting equipment for tunnel secondary lining concrete specially developed for the cutting requirements of secondary lining disease concrete can realize the fully automatic requirements of tunnel circular cutting, greatly improving work efficiency and reducing safety r...
