Abstract

The invention belongs to the technical field of breaking hammers, and particularly relates to an overall impact gravity breaking hammer which comprises a hydraulic brake, a hydraulic motor, a second belt pulley, a first belt pulley, a steel wire wheel, a drill rod, a first pulley, a gravity cavity and a gravity block, wherein the drill rod is mounted inside a drill rod sleeve in such a manner that drill rod guide blocks are in sliding fit with a drill rod sleeve sliding hole; drill rod springs are mounted on the drill rod guide blocks and achieves the function of resetting the drill rod; the gravity block is mounted in the gravity cavity, and winded around the steel wire wheel through a steel wire; the first and second belt pulleys are connected through a belt; a gravity cavity spring is mounted at the upper ends of the gravity cavity and a second outer side plate; the gravity cavity remains at a certain natural position under the own gravity action and the action of the gravity cavity spring; and at the natural position, a certain impact distance is left between the gravity cavity and the drill rod. According to the designed overall impact gravity breaking hammer, the impact strength can be controlled under the action of the hydraulic brake, thereby achieving a relatively high practical effect.

Description

[0001] Technical field [0002] The invention belongs to the technical field of breaking hammers, in particular to an integral striking gravity breaking hammer. Background technique [0003] At present, most breakers use drill rod gravity drive, hydraulic drive, high-pressure gas drive, hybrid drive, etc. to drive the drill rod to reciprocate to break the broken object. Among them, the gravity drive of the drill rod is an important driving method used in special occasions. The drill rod is often required to be very heavy, and the drill rod needs to be raised to a very high height before directly hitting the object to achieve the crushing effect. The drill rod can only be knocked and broken once when it is lifted; when the drill rod needs to be hit hard, the drill rod should be raised to a higher height; This lifting of the chisel rod once, impact once makes the breaking hammer effect of this mode drive very low, has influenced the development of the breaking hammer of this ki...
