Cutting device for expansion joint of bridge

Abstract

The invention relates to the technical field of bridge construction, in particular to a cutting device for an expansion joint of a bridge. The cutting device for the expansion joint of the bridge comprises a base and a machine frame. A first sliding rail and a second sliding rail are correspondingly arranged on the inner wall of the front half part of the machine frame, the first sliding rail andthe second sliding rail are correspondingly provided with a first sliding block and a second sliding block, a motor is installed on the first sliding block, a first rotating shaft is arranged on the motor, and a circular parting tool and a first belt pulley are arranged on the first rotating shaft in a sleeving mode. Bearing seats are arranged on the inner wall of the rear half part of the machineframe, a second rotating shaft is connected between the bearing seats, and a cleaning cylinder and a second belt pulley are arranged on the second rotating shaft in a sleeving mode. A vacuum cleaneris arranged on the upper side of the machine frame. The cleaning cylinder cleans up dust on a bridge deck to-be-cut, so that the circular parting tool can cut accurately, and the quality of cutting ofthe expansion joint is guaranteed; the dust produced by the cutting can be recovered in the vacuum cleaner, so that the pollution degree to the environment is effectively reduced; and the cutting depth of the circular parting tool can be quickly adjusted by an extensible rod and the sliding blocks.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a bridge expansion joint cutting device. Background technique [0002] Bridge expansion joints are generally reserved structures during the construction of bridges, mainly to prevent the safety of the overall bridge from being affected by factors such as temperature changes between bridges. In addition, construction personnel will also use cutting machines to equidistantly space each section of the bridge. Expansion joints are accurately cut out to avoid stress changes in each bridge itself due to temperature changes. [0003] The current cutting device for bridge construction has the disadvantages of flying dust during cutting and polluting the surrounding environment, and sometimes there is mud and dust on the surface of the bridge deck, which hinders the construction personnel from observing the bridge deck and affects the accuracy of cutting.
