Abstract

The utility model relates to the technical field of mechanical equipment, in particular to a hydraulic breaking hammer. The hydraulic breaking hammer comprises an upper cylinder, a middle hydraulic cylinder, a lower cylinder, through bolts and an energy storage assembly, wherein the through bolts penetrate the upper cylinder, the middle hydraulic cylinder and the lower cylinder to be tightened to form a breaking hammer body, regular polygon slotted holes are formed in positions of two sides of the rear end of the upper cylinder and used for connecting the through bolts, concave snap grooves are externally formed in the front of the regular polygon slotted holes, a drill rod is arranged in a cavity of the upper cylinder, two flat lock pins are arranged on the upper cylinder, the flat lock pins are inserted into two sides of the drill rod respectively, key grooves are formed in the drill rod, a guide sleeve and a drill rod retainer bush are disposed in the cavity of the upper cylinder, an exhalation valve is mounted on the middle cylinder, the lower cylinder is a nitrogen chamber, and the nitrogen chamber is located in rear of a piston. According to the hydraulic breaking hammer, during usage, the own structure is reasonably utilized, the pressure of the through bolts is relieved, the service life of the through bolts is greatly prolonged, and the hydraulic breaking hammer is reasonable in structure, low in costs and easy to accept in market.

Description

A kind of hydraulic breaking hammer
Technical field
The utility model relates to the technical field of plant equipment, especially a kind of hydraulic breaking hammer.
Background technology
Hydraulic breaking hammer is that one can be mechanical energy by hydraulic energy transfer, thereby the facility that externally do work are mainly used in the work such as fragmentation, dismounting, excavation hard formation, are conventionally arranged on excavator, loader or power station.At present conventional hydraulic breaking hammer is mainly made up of the housing for connecting excavator, loader or power station and hammer core.Quartering hammer in use has rigidity fatigue, and shank of bolt runs through total and connects, and the of long duration shank of bolt that will make produces slight crack or even fracture; And quartering hammer must have wearing and tearing between cylinder body in use.
Summary of the invention
The purpose of this utility model is to provide a kind of rational in infrastructure, hydraulic breaking hammer that cost is low, practical.
For meeting above-mentioned purpose the technical solution of the utility model be: a kind of hydraulic breaking hammer, comprise cylinder in upper cylinder half, hydraulic pressure, lower cylinder, pass through body bolt, accumulation of energy assembly, describedly pass through cylinder in body bolt-through upper cylinder half, hydraulic pressure, lower cylinder and tension is breaking hammer main body, the regular polygon slotted eye that offers of the both sides of described upper cylinder half rear end passes through body bolt for connecting, the upper outside spill screens groove that is provided with above of the regular polygon hole slot of telling; In the chamber of described upper cylinder half, be provided with drill steel, upper cylinder half is provided with two flat lock pins, and described flat lock pin inserts in respectively the both sides at drill steel; On described drill steel, offer keyway; In described upper cylinder half chamber, be provided with fairlead and drill steel retainer lining, on the rear end face of described drill steel, overlap flexible pad, the output that is provided with piston rod, described piston rod in described hydraulic pressure in cylinder stretches in upper cylinder half follows the rear end face of drill steel corresponding, described accumulation of energy assembly is located in hydraulic pressure on cylinder, and accumulation of energy assembly has connection with the piston in cylinder in hydraulic pressure; On described middle cylinder, offer outlet valve; Described lower cylinder is nitrogen chamber, described nitrogen chamber be positioned at piston after, on described lower cylinder, offer nitrogen valve opening.
Described fairlead is set on the drill steel in exit of drill steel seat, and described drill steel retainer lining is located at the rear end of drill steel.
The inwall of described regular polygon slotted eye is provided with beam.
On inwall between described two adjacent cylinder bodies, be all embedded with beam.
Beneficial effect: the utility model has rationally utilized the structure of self in use, has shared the pressure that passes through body bolt, improves its life-span greatly, and the utility model is rational in infrastructure, cost is low, is easily accepted by market.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
