Description
Technical field
The utility model relates to construction machine field, particularly a kind of hydraulic breaking hammer.
Background technology
Hydraulic breaking hammer is called for short " quartering hammer " or " destroyer ", the pressure that the power resources of hydraulic breaking hammer are excavators, loader or pumping plant provide, and it can more effective broken stone and rock in engineering construction, increases work efficiency.
Operationally, a large amount of earth dusts causes damage through lining to equipment to traditional quartering hammer, easily external bushing in wearing and tearing, and lubricating grease and dust very easily enter cylinder interior and cause hydraulic oil pollution (as blackening, have impurity and go bad).Have a strong impact on excavator use cost and life-span.In high speed operation situation, noise also very large, causes very large impact to the physical and mental health of staff.
Summary of the invention
The purpose of this utility model is just to provide a kind of dust control and noise absorption sound hydraulic breaking hammer, and structure simpler production is convenient, and effective preventing dust dirty oil, anti-impurity, anti-metamorphic etc., effectively reduce use cost.
Technical problem of the present utility model is solved mainly through following technical proposals:
A kind of dust control and noise absorption sound hydraulic breaking hammer, comprises cylinder body, it is characterized in that: described cylinder body shell is integral type, cylinder body shell upper end is provided with storage bin, drill steel is fixed in cylinder body lower end, is also provided with metal lining between described cylinder body lower end and drill steel, establishes activity hypertonic ring in this metal lining.
Further, described metal lining cross section is thin lower loose in " convex " font, an arc groove is respectively provided with about this metal lining upper part, under this metal lining, part inwall is provided with inner ring groove, described activity hypertonic ring is assemblied in this inner ring groove, has space between this activity hypertonic ring and inner ring groove.
Further, described storage bin is provided with oil filler and one-way throttle valve at cylinder body housing top end place, and described oil filler is connected inner carrier strike place of cylinder body front end with one-way throttle valve by flexible pipe.Under oil condition filled it up with by described storage bin, hydraulic oil flows to cylinder body front end through one-way throttle valve, flexible pipe, plays cleaning cylinder body piston region lubricating grease thus reaches the effect preventing dirty oil.Also can substitute one-way throttle valve with direct joint, now storage bin non-refuelling, its piston moves back and forth generation air-flow in cylinder body front end, produces resistance, thus reach the effect of noise reduction through flexible pipe guiding storage bin.
Further, described activity hypertonic ring is formed by three eccentric circular rings and spring assembling, and described eccentric circular ring is 120 degree of fan shapes, and eccentric circular ring two ends are provided with breach, and its breach of adjacent eccentric circular ring is complementary.Activity hypertonic ring can move around in metal lining inner ring groove, thus reduces to minimum for drill steel friction.
Further, U-lag is provided with outside described eccentric circular ring for assembling spring.
Further, described spring is around the end to end tension of U-lag.Play hypertonic effect after tension, quartering hammer and drill steel are combined closely, thus prevents dust from entering in cylinder body.
Further, also sealing mat is provided with between described activity hypertonic ring and inner ring groove.
Further, described quartering hammer shell is two kinds, and a kind of is straight type (also claiming tower), and another kind is triangular form, and described storage bin is all located at cylinder body shell upper end.
The beneficial effects of the utility model are: the utility model have employed a kind of large space storage bin on traditional quartering hammer, serve the effect of damping and silencing and cleaning cylinder body piston lubrication fat, in addition, also developed activity hypertonic ring, fitted seal pad and spring straining process, effectively prevent mud dirt from being entered in quartering hammer cylinder body hydraulic oil pollution by the gap between lining and drill steel, make its blackening, go bad and increase the situations such as impurity, activity hypertonic ring moves along with drill steel, at utmost reduce the frictional force that drill steel brings, its practicality is very strong, effectively reduce costs, increase the service life.

Detailed description of the invention
Below by embodiment, and 1-2 by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
A kind of dust control and noise absorption sound hydraulic breaking hammer, comprise cylinder body 1, described cylinder body 1 shell is integral type, cylinder body 1 shell upper end is provided with storage bin 2, drill steel 8 is fixed in cylinder body 1 lower end, is also provided with metal lining 5 between described cylinder body 1 lower end and drill steel 8, establishes activity hypertonic ring 6 in this metal lining 5.
Described metal lining 5 cross section is thin lower loose in " convex " font, is respectively provided with an arc groove 502 about this metal lining 5 upper part, and this metal lining 5 times part inwalls are provided with inner ring groove 501, and described activity hypertonic ring 6 is assemblied in this inner ring groove 501.Between this activity hypertonic ring 6 and inner ring groove 501, there is space.Described storage bin 2 is provided with oil filler 3 and one-way throttle valve 4 at cylinder body 1 housing top end place, and described oil filler 3 is connected strike place of cylinder body inner carrier with one-way throttle valve 4 by flexible pipe 7.Piston moves back and forth generation air-flow in cylinder body 1, produces power-assisted, thus reach the effect of noise reduction through flexible pipe 7 storage bin 2 that leads.Also one-way throttle valve 4 can be substituted with straight coupling.
