Abstract
The utility model discloses a crushing device of a road surface crusher, which comprises a plate hammer frame, a plate hammer and an operating cylinder, wherein the plate hammer is positioned in the plate hammer frame and can move from top to bottom in the plate hammer frame, the operating cylinder is fixed on the plate hammer frame and a lifting device is arranged between the plate hammer and the operating cylinder. The lifting device comprises a pulley wheel which is fixed on the top end of a piston rod of the operating cylinder and a pull rope which is used for pulling the plate hammer, wherein one end of the pull rope is connected with the plate hammer and the other end of the pull rope is fixed on the plate hammer frame. The operating cylinder is under the action of high pressure oil, when the piston rod moves upwards, the plate hammer can be moved upwards along the plate hammer frame through the action of the pulley wheel and the pull rope. When the high pressure oil in the operating cylinder is poured out, the plate hammer can rapidity slide downwards along the plate hammer frame. Because the weight of the plate hammer is larger, cement concrete floors or other floors can be easily crushed, the better crushing effect can be achieved, and moreover, the work efficiency is high.
Description
Technical field
The utility model relates to the road building machinery field, in particular, relates to a kind of breaker of road breaker.
Background technology
Usually, the maintenance on cement concrete ground and maintenance, traditional maintenance mode is with artificial or mechanical system fragmentation to be carried out on ground, keep in repair then, manual type generally is applicable to the repairing work on fritter ground owing to waste time and energy, large-scale ground maintenance engineering generally adopts mechanical system to carry out operation, also there is multiple mode in mechanical work at present, as a kind of utility model patent that be called " hand-held hydraulic hammer " of State Patent Office in bulletin on November 20th, 1988, this frame for movement is simple, easy to use flexible, but because the dynamics on impact road surface is limited, so broken is of low quality, operating efficiency is also lower, can not adapt to the bigger road surface of workload safeguards, State Patent Office is in a kind of utility model patent that is called " road surface hydraulic breaker " of bulletin on October 23rd, 1996, mainly be in order to substitute the road surface operation that large excavator is carried out, the quality and the efficient of work are all lower, and aforesaid way all is to finish repairing work by changing the road surface fragment, the cement pavement fragment that more swaps out causes other pollution again, the waste ample resources.
Summary of the invention
The purpose of this utility model provides the breaker of a kind of high efficiency, a kind of road breaker that crushing effect is good.
For achieving the above object, the technical scheme that the utility model adopted is: a kind of breaker of road breaker, comprise bar frame, bar and operating cylinder, it is characterized in that: described bar is positioned at the bar frame, described bar can move up and down in the bar frame, described operating cylinder is fixed on the bar frame, be provided with lifting device between described bar and the operating cylinder, described lifting device comprises the pulley that is fixed on operating cylinder piston rod top, the pull rope of traction bar, one end of described pull rope is connected with bar, and the other end is fixed on the bar frame.
Beneficial effect: the utility model adopts said structure, operating cylinder is fixed on the bar frame, a pulley is fixed on the top of operating cylinder piston rod, pull rope is connected with bar by an end, the other end is fixed on the bar frame and draws bar, operating cylinder is under the effect of hydraulic oil, when piston rod moves upward, effect by pulley and pull rope, bar can move up along the bar frame, and when the hydraulic oil in the operating cylinder gushed, bar glided rapidly along the bar frame, because the weight of bar is bigger, so can reach crushing effect preferably, and operating efficiency be higher easily with cement concrete ground or other ground fragmentation.
Below be the improvement of such scheme:
Described bar has set up track.
The setting up of track is beneficial to bar and moves up and down.
Described bar sets up the cover of wedge of fixed tractive.
Pull rope can better be fixed and change to cover of wedge.
Described track liner high-strength nylon.
The setting of high-strength nylon both can reduce the friction of bar and bar frame, can cushion the rigid impact in bar and bar frame rail road again.
The utility model is described in further detail below in conjunction with drawings and Examples.
