Roughening device with self-adaptive cambered surface and roughening method thereof

Abstract

The invention discloses a roughening device with a self-adaptive cambered surface. The roughening device with the self-adaptive cambered surface comprises a mounting base capable of swinging up and down, wherein a roughening part and two distance measuring parts are arranged on the mounting base; and the two distance measuring parts are arranged on the upper side and the lower side of the roughening part respectively. The invention further discloses a roughening method of the roughening device with the self-adaptive cambered surface. The roughening method comprises the following steps: S1, measurement: the distances between the distance measuring parts on the upper and lower sides and a working cambered surface are measured as a and b respectively, and if |a-b| is within a set range, the step S2 is carried out; if |a-b| exceeds the set range and a-b is larger than 0, the mounting base swings downwards until |a-b| is reduced to the set range, and then the step S2 is executed; if |a-b| exceeds the set range and a-b is smaller than 0, the mounting base swings upwards until |a-b| is reduced to the set range, and then the step S2 is carried out; and S2, roughening work conducted by theroughening part. The roughening device with self-adaptive cambered surface provided by the invention has the advantages of being simple in structure, wide in application range, beneficial to keeping perpendicular to the operation cambered surface, and the like.

Description

technical field [0001] The invention relates to tunnel construction equipment and a construction method thereof, in particular to a chiseling device and a chiseling method for an adaptive curved surface. Background technique [0002] During the construction of the tunnel, the secondary lining concrete should be chiseled to improve the adhesion of the concrete surface and make the construction surface of the two construction stages bond firmly. At present, tunnel chisel methods mainly include artificial chisel, airborne chisel chisel and tunnel special chisel chisel. Regardless of the chiseling method, construction tools such as chisel heads, electric picks, and hydraulic picks are required to be as vertical as possible to the working surface. The existing manipulators can basically meet the above requirements for a relatively flat working surface, but for the side wall of the tunnel, construction When the tool moves along the arc surface with the manipulator, the stability ...

Regardless of the chiseling method, construction tools such as chisel heads, electric picks, and hydraulic picks are required to be as vertical as possible to the working surface. The existing manipulators can basically meet the above requirements for a relatively flat working surface, but for the side wall of the tunnel, construction When the tool moves along the curved surface with the manipulator, the stability is poor, which is not conducive to keeping it perpendicular to the working curved surface
