Abstract
The utility model discloses a novel middle cylinder sealing structure for a hydraulic breaking hammer. The structure comprises a buffer seal, two piston rod sealing elements, a dustproof oil seal and an oil circuit, the buffer seal, the piston rod sealing elements and the dustproof oil seal are arranged between a middle cylinder and a piston and positioned in corresponding grooves in the middle cylinder, the piston rod sealing elements are arranged between the buffer seal and the dustproof oil seal, the oil circuit is arranged on the middle cylinder, the two piston rod sealing elements are symmetric about an oil hole, the oil hole is formed between the two piston rod sealing elements and communicated with the oil circuit, and a sealing plug is arranged at an oil inlet of the oil circuit. Based on a traditional seal, one special piston rod sealing element is added, the oil hole is used for lubricating the sealing elements, an oil film is formed by the sealing elements, the sealing performance of the middle cylinder of the hydraulic breaking hammer is greatly improved, unnecessary maintenance is avoided, and maintenance cost is reduced.
Description
Technical field
The utility model relates to a kind of sealing configuration, is specially sealing structure of cylinder in a kind of Novel hydraulic crushing hammer.
Background technique
Hydraulic breaking hammer is due to sealing place of middle cylinder body and piston, during work, in a large amount of dusts, sand grains, rubble powder, add the grain of upper piston rod oil film assorted, high speed piston motion, often because poor sealing causes hydraulic breaking hammer leakage of oil, have a strong impact on the usability of hydraulic breaking hammer, cause working efficiency to reduce.
Summary of the invention
In order to solve problems of the prior art and deficiency, the utility model provides sealing structure of cylinder in a kind of Novel hydraulic crushing hammer, on conventional seals basis, increase piston rod dedicated sealing member, and oilhole is set Sealing is lubricated, make Sealing form one deck oil film, greatly promoted the sealability of cylinder body in hydraulic breaking hammer.
The purpose of this utility model realizes by the following technical solutions.
Sealing structure of cylinder in a kind of Novel hydraulic crushing hammer, in structure, comprise cushion seal, piston rod seal component, anti-dust seal, also comprise oil circuit, cushion seal, piston rod seal component, anti-dust seal are arranged at middle cylinder body with piston space and are arranged in groove corresponding on cylinder body, between cushion seal and anti-dust seal, be provided with piston rod seal component, oil circuit is arranged on middle cylinder body.
Described piston rod seal component, has two, along oilhole, is symmetrical set, and adds and increase by one Sealing on the basis of original one piston rod seal component, promotes its sealability.
Between two described piston rod seal components, be provided with an oilhole, oilhole and oil circuit UNICOM, be provided with sealing plug on the filler opening of oil circuit.
The utility model is on conventional seals basis, increase piston rod dedicated sealing member, and oilhole is set Sealing is lubricated, make Sealing form one deck oil film, greatly promoted the sealability of cylinder body in hydraulic breaking hammer, can there is not Leakage, and avoid unnecessary maintenance, reduce maintenance cost.

Fig. 2 is the utility model one example structure schematic diagram
In figure: cylinder body in 1-, 2-cushions oil sealing, 3-piston rod seal component, 4-anti-dust seal, 5-piston, 6-piston rod seal component, 7-oilhole, 8-oil circuit.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 2, sealing structure of cylinder in a kind of Novel hydraulic crushing hammer, in structure, comprise cushion seal, piston rod seal component, anti-dust seal, also comprise oil circuit, cushion seal, piston rod seal component, anti-dust seal are arranged at middle cylinder body with piston space and are arranged in groove corresponding on cylinder body, between cushion seal and anti-dust seal, be provided with piston rod seal component, oil circuit is arranged on middle cylinder body.
Further, described piston rod seal component, has two, along oilhole, is symmetrical set, and adds and increase by one Sealing on the basis of original one piston rod seal component, promotes its sealability.
Further, between two described piston rod seal components, be provided with an oilhole, oilhole and oil circuit UNICOM, be provided with sealing plug on the filler opening of oil circuit.
The utility model, on conventional seals basis, increases piston rod dedicated sealing member, and oilhole is set Sealing is lubricated, make Sealing form one deck oil film, greatly promote the sealability of cylinder body in hydraulic breaking hammer, avoided unnecessary maintenance, reduced maintenance cost.
