Breaking hammer with shearing device

Abstract

Disclosed is a breaking hammer with a shearing device. A shearing mechanism of the breaking hammer comprises a hydraulic motor, wherein the hydraulic motor is fixed to the side wall of a breaking hammer body. A rotating shaft of the hydraulic motor and the upper end of a vertical lead screw are connected together through a coupler, and the lower end of the lead screw is hinged to a base. The base is fixed to the side wall of the breaking hammer body. A shearing knife is arranged on the lower side of the base, and comprises two staggered and symmetrical blades. Rectangular piece bodies which extend upwards are formed on the blades, vertical guide grooves are formed in the rectangular piece bodies, and the guide grooves of the two blades overlap together. A guide column is inserted into the guide grooves in a connected mode, and fixed to the side wall of the breaking hammer body. Inclined connecting rods are formed at the upper ends of the rectangular piece bodies of the blades. A rectangular sliding block is connected to the lead screw in a screwed mode, and abuts against the side wall of the breaking hammer body, supporting rods are formed on the two sides of the sliding block, and the top ends of the connecting rods on the blades are hinged to the supporting rods. The breaking hammer is provided with the shearing mechanism, and the shearing mechanism can be hydraulically driven to shear off rebars in the construction process.

Description

Technical field:

[0001] The invention relates to the technical field of breaking hammers, in particular to a breaking hammer with a shearing device. 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. In particular, some ground foundation steel bars are still quite thick, and the general manual cutters are all cut continuously, and it has to be handled by other personnel and tools, 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. In the proce...
