The hammer not only has small volume and compact structure, but also can overcome the weakness that the return force of the piston damages the cylinder body.
Description
Technical field
The utility model relates to a kind of hydraulic breaking hammer.
Technical background
At present, the hydraulic breaking hammer structure adopts each flow of external valve regulated cylinder body more, utilizes the kinetic energy of saving of piston region diameter difference and accumulator, makes piston up-down, promotes drill steel and impacts material, to reach broken purpose.With the return dynamics of nitrogen pressure damper piston in the nitrogen chamber, there has been the protection cylinder body to avoid the effect of impact failure, but because external valve, so moulding is bigger, and structure is not compact, and nitrogen pressure often loses to reduce and causes that cylinder body damages in addition.
The utility model content
The purpose of this utility model is to provide a kind of no nitrogen chamber valve built-in hydraulic breaking hammer, and it is not only small, compact conformation, and can overcome the piston screen resilience causes damage to cylinder body shortcoming.
For achieving the above object, the solution that the utility model is taked is: the built-in hydraulic breaking hammer of a kind of no nitrogen chamber valve, it comprises cylinder body and cover cylinder seat in its back-end, the afterbody of cylinder seat is connected with accumulator, be equipped with the nitrogen bag in the middle of the accumulator, cylinder cap covers the tail end at cylinder body, front stall is contained in the front portion of cylinder body, double-screw bolt tightens up cylinder seat and front stall while stationary housing and cylinder cap, piston is placed in the middle of the cylinder body, distributor is contained in the rear end of piston and is in the front end of cylinder cap, at piston, distributor, place spool in the middle of the cylinder cap three, piston, distributor, cylinder cap, spool and cylinder body constitute a multidigit valve, drill steel is placed among the front stall and is in before the piston, has several oilholes on the cylinder body, has oil input channel and oil road in the cylinder seat, the both wings of cylinder seat are furnished with the hydraulic oil in-out apparatus, oil circuit communicated cylinder seat, cylinder body, cylinder cap, accumulator, distributor, spool.
The utility model utilizes the effect of the built-in multiposition valve of piston tail and the kinetic energy of saving of cylinder seat afterbody accumulator to make the piston resilience; when piston springs back to a certain degree; effect by the multidigit valve; very fast alleviation screen resilience dynamics is utilized nitrogen bag in the accumulator again, prevents that nitrogen pressure from reducing; protect cylinder body effectively in order to avoid the piston resilience is impacted and damaged; again because no nitrogen chamber and external valve, not only small, compact conformation, and can reduce in-fighting.
Description of drawings
Fig. 1 is the structural representation of present embodiment.
Among the figure: 1, accumulator, 2, the nitrogen bag, 3, cylinder cap, 4, spool, 5, distributor, 6, the cylinder seat, 7, cylinder body, 8, double-screw bolt, 9, piston, 10, the back cover, 11, front stall, 12, drill steel, 13, protheca, 14, oil input channel, 15, oil road, 16, oilhole.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Referring to Fig. 1, the built-in hydraulic breaking hammer of a kind of no nitrogen chamber valve, it comprises cylinder body 7 and cover cylinder seat 6 in its back-end, the afterbody of cylinder seat 6 is connected with accumulator 1, be equipped with nitrogen bag 2 in the middle of the accumulator 1, cylinder cap 3 covers the tail end at cylinder body 7, front stall 11 is contained in the front portion of cylinder body 7, double-screw bolt 8 tightens up cylinder seat 6 and 11 while of front stall stationary housing 7 and cylinder cap 3, piston 9 is placed in the middle of the cylinder body 7, distributor 5 is contained in the rear end of piston 9 and is in the front end of cylinder cap 6, at piston 9, distributor 5, place spool 4 in the middle of cylinder cap 3 threes, piston 9, distributor 5, cylinder cap 3, spool 4 and cylinder body 7 four constitute a multidigit valve, drill steel 12 is placed among the front stall 11 and is in before the piston 9, has several oilholes 16 on the cylinder body 7, has oil input channel 14 and oil road 15 in the cylinder seat 6, the both wings of cylinder seat 6 are furnished with the hydraulic oil in-out apparatus, oil circuit communicated cylinder seat 6, cylinder body 7, cylinder cap 3, accumulator 1, distributor 5, spool 4.
Referring to Fig. 1, the back middle dress back cover 10 of described front stall 11, the preceding middle protheca 13 of adorning.
Referring to Fig. 1, have 12 oilholes 16 on the described cylinder body 7.
Referring to Fig. 1, its operation principle is summarized as follows: when oil circuit one open-minded, promote distributor 5, close oil road 15, propelling piston 9, the hydraulic oil of piston 9 anterior oil pockets is discharged to the accumulator 1 from oilhole 16, piston 9 advances, and impacts drill steel 12, reaches the purpose of broken object, piston 9 is advanced to certain position, distributor 5 cuts out oil input channel 15 automatically, opens oil road 14, and the hydraulic oil in the accumulator 1 injects piston 9 anterior oil pockets from oilhole 16, make piston 9 return, piston 9 begins ahead running again behind certain position ... so move in circles.
