The breaking hammer is characterized in that the rear cylinder body, on which a breather valve is added, is provided with a nitrogen chamber; and the breather valve is communicated with a piston cavity in the middle rear cylinder body through a pipeline. Compared with the prior art, the breaking hammer has the advantages of convenient processing, high working reliability, and great hitting power (increased by 15% compared with the prior hydraulic breaking hammer), thereby realizing high impact power.
Description
Technical field
The utility model belongs to engineering machinery and mining machinery technical field, is specifically related to the built-in hydraulic breaking hammer of a kind of HI high impact merit.
Background technology
In the hydraulic breaking hammer product design at present, the external valve arrangement of most of employing, reversal valve is outside middle cylinder body, product causes parts more, sealing difficulty, spool are once wearing and tearing, and whole reversal valve then needs more to renew valve and a complete set of seal, external reversal valve and middle cylinder body palpus fit sealing is rolled over very inconvenience of dress in maintenance process simultaneously.And beat inclined hole than multi-processing inconvenience in the middle cylinder body process, and production efficiency is low, and cost is too high.Cylinder body is provided with the air inlet/outlet that is communicated with plunger shaft in the hydraulic breaking hammer, move up and down the negative pressure that in plunger shaft, forms for reducing piston rod, but this air inlet/outlet position is near apart from drill steel, and the dust of Xing Chenging easily stops up air inlet/outlet at work, has reduced to be the ballistic work of hydraulic breaking hammer.
Summary of the invention
For overcoming the above-mentioned defective that prior art exists, it is a kind of easy to process that the purpose of this utility model is to provide, functional reliability height, the built-in hydraulic breaking hammer of HI high impact merit that hitting power is big.
For achieving the above object, the utility model adopts technical scheme to be: the built-in hydraulic breaking hammer of this HI high impact merit is made up of frame, drill steel, lower cylinder body, middle cylinder body and rear-bank rotor housing, it is characterized in that: described rear-bank rotor housing has nitrogen chamber, set up breather valve on the rear-bank rotor housing, breather valve is connected with middle cylinder piston chamber by pipeline.
Cylinder body is provided with built-in reversal valve in described, described built-in reversal valve is a valve body with middle cylinder body, offer valve opening on the valve body, be communicated with the oil duct of cylinder body oil cylinder in leading on the valve opening inwall, be provided with the valve pocket that is mated in the valve opening, be provided with spool in the valve pocket, the end of valve opening is provided with valve gap, described valve opening is a unthreaded hole, and the position of the corresponding oil duct opening of the outer wall of described valve pocket offers ring-shaped groove, is connected by oilhole between ring-shaped groove and the valve pocket centre bore.
The pipeline of described breather valve is the gap that forms after the bolt hole of fastening rear-bank rotor housing cooperates with fastening bolt, and the end of bolt hole has the intercommunicating pore that is communicated with bolt hole and middle cylinder piston chamber, is provided with screen pack in the breather valve.
The nitrogen chamber of described rear-bank rotor housing and the connecting portion of middle cylinder body are provided with the two seals ring.
Adopt the beneficial effect of technique scheme to be: the rear-bank rotor housing of the built-in hydraulic breaking hammer of this HI high impact merit has nitrogen chamber, promote pistons work simultaneously by hydraulic oil and the expansion of rear portion compressed nitrogen, be beneficial to strengthen upwards thrust, thereby improved the ballistic work of hydraulic breaking hammer; One sealing ring prevents that nitrogen from leaking on the rear-bank rotor housing, improves rear-bank rotor housing and fills nitrogen pressure, makes the interior nitrogen the blowing pressure of former rear-bank rotor housing by 16kg/cm
2, bring up to 20kg/cm
2, nitrogen storage energy effect is better.Set up breather valve on the rear-bank rotor housing, breather valve is connected with middle cylinder piston chamber by pipeline, make breather valve apart from drill steel than distant positions, avoid the obstruction of breather valve, piston rod is moving up and down Shi Buhui in position, middle cylinder piston chamber generation negative pressure, reduce the resistance of piston activity, piston is efficiently moved, guaranteed the HI high impact merit of hydraulic breaking hammer, hydraulic breaking hammer change-over valve is a valve body with middle cylinder body, offer valve opening on middle cylinder body, the valve opening structure is a smooth inner bore, and the former ring-shaped groove that is located on the valve opening inwall is changed on the outer wall that is located at valve pocket, the valve pocket cooperation is assemblied in the valve opening, be provided with spool in the valve pocket, the end of valve opening is provided with valve gap, and reversal valve is rational in infrastructure, cost is low, commutation ability is reliable, has solved the problem of external sealing, and is easy to maintenance.Compared with prior art, the hitting power of this built-in hydraulic breaking hammer increases by 15%, has realized the HI high impact merit.
