Breaking hammer with cutting function

Abstract

The invention discloses a breaking hammer with a cutting function. The breaking hammer with the cutting function mainly comprises a breaking hammer, a cutter, a supporting arm and a hydraulic cylinder. The breaking hammer mounted at a lower end of a bucket arm of an excavator is mainly used for impacting rocks, dismantling old buildings, impacting and breaking a cement building foundation and a to-be-constructed concrete pavement; when a cement pouring body is broken to expose steel bars, especially very thick steel bars, a construction progress is severely affected. According to the device, the shaft arm type cutter is mounted behind clamping plates of an existing breaking hammer through a hinge. When the steel bars are cut, a cutter body of the cutter rotates around the hinge under the action of the hydraulic cylinder to leave from the breaking hammer and is expanded outwards and supported, so that cutting can be carried out. After cutting is finished, the cutter body of the cutter is pulled back into a space between the two clamping plates of the breaking hammer through the hydraulic cylinder, so that the structure and appearance of the existing breaking hammer are not changed. The device can be used for cutting the steel bars, tree roots and tree branches, and also can be used for cutting the to-be-constructed cement pavement, the hard rocks and the like. The steel bars are exposed in a process of hitting and breaking the cement pouring body, and both hitting and cutting can be simultaneously carried out, so that great convenience is brought to construction and the working efficiency is improved.

Description

technical field [0001] The invention relates to a breaking hammer matched with excavating machinery, especially a breaking hammer with cutting function. Background technique [0002] Existing breaking hammer is mainly used for impacting rock, cement pavement, cement pouring foundation, old building demolition etc., has unique effect. When dismantling the cement pouring frame of the old building, especially the ground foundation, after impacting and breaking the cement block, the steel bars are exposed and cannot be cut off. Especially some foundation steel bars on the ground are still quite thick, and the general large shears are all cut continuously, and it is necessary to wait for other personnel to handle them, and the work of the breaker is often interrupted and then continued. There are often many small steel bars in the cement body, and they have to be manually cut and then continue to impact, which affects the construction progress and brings trouble to the workers. ...
