Description
Technical field
The present invention relates to a kind of quartering hammer, is a kind of vibro-impact crushing hammer specifically.
Background technology
Current broken market mainly contains engineering fragmentation, the broken engineering such as to repair the roads in open a mine fragmentation and mountain area.In these broken engineerings, the broken dominating impact formula of hard is broken for master, but noise and dust pollution are seriously, seriously disturb residents, the conflict that general construction period all can be sent out either large or small.Because the hardness of rock declines during severely-weathered rocks construction, impact cannot direct operation, explosive manages strictly at present, so a lot of local vibrating type that adopts is broken, but due to the irregular reason of geologic structure, often along with slightly weathered rock in severely-weathered, whole engineering construction is made to run into obstacle, so devise the impact-vibration-type pile hammer simultaneously with impact shock crushing function based on this.
Summary of the invention
For above-mentioned situation, the invention provides a kind of vibro-impact crushing hammer, adopt impact grinding pattern after first vibration, decline due to the hardness of rock when the structure that vibratory impulse is taken into account solves the construction of severely-weathered rocks, impact cannot direct operation; And severely-weathered in often along with slightly weathered rock, make the fragmentation of common vibrating type run into the problem of obstacle.Noise of the present invention is low, and the feature of environmental protection is good.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of vibro-impact crushing hammer, comprise body structure, hydraulic motor, hydraulic switching device, it is characterized in that, also involving vibrations device, beater mechanism, drill rod for breaking, drill steel fixed cover, beater mechanism is connected with hydraulic switching device, described beater mechanism comprises at least one percussion mechanism, percussion mechanism comprises impact piston, impact cushion block, piston packing ring, accumulator, impact piston to be located in piston packing ring and piston packing ring is separated into upper oil cavitie and lower oil cavitie, impact cushion block is provided with bottom piston packing ring, impact below cushion block and be provided with drill rod for breaking, drill steel fixed cover is provided with outside drill rod for breaking, drill steel fixed cover is arranged on bottom body structure, described vibrating device comprises at least two group eccentric stiffeners, described beater mechanism is located in the middle part of body structure, eccentric stiffener is located in body structure, and be symmetrically distributed in beater mechanism both sides, and symmetrically arranged one group of eccentric stiffener is positioned on same level height, described eccentric stiffener involving vibrations eccentric block, eccentric block driving shaft, eccentric block driving shaft is provided with vibration eccentric block, eccentric block driving shaft is connected to hydraulic motor, also comprise gear-box, the spacing vibration pinion of balance is provided with in gear-box, balance spacing vibration gear wheel, eccentric block driving shaft is provided with the spacing vibration gear wheel of balance, balance spacing vibration gear wheel to be connected with a joggle with the spacing vibration pinion of balance, be symmetricly set on a group of percussion mechanism both sides to balance between spacing vibration pinion and be connected with a joggle.
Also comprise lifting linkage, body structure top is located at by lifting linkage.
Also comprise damper, damper is located between lifting linkage and body structure, and described damper is double-layer rubber structure.
Advantage of the present invention is: the eccentric block that the present invention utilizes two groups or even number set to be symmetrically distributed produces the centrifugal force to external diffusion in rotary course, symmetrical and constraint eliminates the centrifugal force of half, and second half centrifugal force acts directly on body structure owing to retraining, by the vibration of the drill rod for breaking be arranged on bottom body structure and drill steel fixed cover up-and-down reciprocating.Declines due to the hardness of rock when solving the construction of severely-weathered rocks, impact cannot the problem of direct operation.Run into severely-weathered in often along with slightly weathered rock, when making common vibrating type fragmentation run into obstacle, the percussion mechanism set up can carry out impact grinding pattern, and the structure that vibratory impulse is taken into account makes the present invention be applicable to most construction site, and noise is low, the feature of environmental protection is good.Design of the present invention reduces to open a mine the engineering such as to cut into a mountain to the degree of dependence of explosive and construction equipment purchase cost, improves the open a mine construction profit of engineerings such as cutting into a mountain and the overall utilization rate of equipment.
