Description
Technical Field
The utility model belongs to the technical field of the hydraulic pressure quartering hammer, concretely relates to piston uide bushing for hydraulic pressure quartering hammer.
Background
The hydraulic breaking hammer is one kind of machine capable of converting pressure energy into mechanical energy to do work outwards, and it uses hydrostatic pressure as power to drive the piston inside to reciprocate, and the piston strikes the drill rod at high speed during stroke, so that the drill rod breaks ore, concrete and other solid for breaking, demolishing and other work.
A piston guide sleeve is arranged between an upper cylinder body of the hydraulic breaking hammer and a piston, and an air seal and an oil seal are arranged on the piston guide sleeve, so that the installation of the piston of the hydraulic breaking hammer is met, the leakage of hydraulic oil and air is avoided, and the reciprocating motion of the piston is guided.
As shown in figure 1, the piston guide sleeve in the existing hydraulic breaking hammer is only provided with the air seal and the oil seal, so that the axial constraint force on the piston is small, the length is short, the piston cannot be well supported and guided, the piston is easy to deviate in the motion process, the operation is not stable enough, and the service life of the hydraulic breaking hammer is influenced.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model aims to provide a piston guide sleeve for a hydraulic breaking hammer.
The above object of the present invention is achieved by the following technical solutions:
the utility model provides a piston uide bushing for hydraulic breaking hammer, its constitution includes: piston uide bushing 3, there are two recesses in the outside of piston uide bushing 3, every all be equipped with sealing washer 3-1 on the recess, 3 inboards from left to right are equipped with the stet seal groove A in proper order, stet seal groove B, direction annular, stet seal groove C, airtight seal groove in the piston uide bushing, be provided with airtight seal 3-2, stet seal 3-3, guide ring 3-4 respectively in gas seal groove, the stet seal groove, the guide ring evenly run through on the piston uide bushing lateral wall between stet seal groove B, the guide ring have 8 ~ 10 oil gallery 3-5, each oil gallery 3-5 is close to the inboard one end of piston uide bushing outer wall and caves in and forms inboard oil gallery, each oil gallery 3-5 is close to the outside one end of piston uide bushing outer wall and caves in and forms outside oil gallery.
Further, two sections of diameter sections with different diameters are formed on the outer side of the piston guide sleeve 3, wherein the larger diameter section is matched with the middle cylinder body of the hydraulic breaking hammer, and the smaller diameter section can extend into the rear cylinder body of the hydraulic breaking hammer.
The utility model discloses a piston uide bushing for hydraulic pressure quartering hammer can play better support guide effect to the motion of piston to guarantee that the motion is more stable, difficult production skew, the life of extension hydraulic pressure quartering hammer.
