Abstract

The invention belongs to the technical field of breaking hammers, and particularly relates to an pull-rope-type gravity breaking hammer which comprises a hydraulic motor, a second pulley, a first steel wire wheel, a clutch ring, a second steel wire wheel, an impact block, 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; through a first steel wire, the gravity block passes through the first pulley and is winded around the steel wire wheel; the steel wire wheels are driven by the hydraulic motor; under the control of the hydraulic motor, the second steel wire wheel is rotated to wind the first steel wire, thereby controlling the rise and fall of the gravity block; and the first steel wire wheel is separated from a motor rotating shaft, so that the separation and reunion of the first steel wire wheel and the motor rotating shaft can be controlled by adjusting the clutch ring. According to the designed pull-rope-type gravity breaking hammer, the impact strength can be controlled under the action of the clutch ring, thereby achieving a relatively high practical effect.

Description

Technical field [0001] The invention belongs to the technical field of breaking hammers, in particular to a rope-drawn gravity breaking hammer. Background technique [0002] 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 kind of driving m...
