Description
Technical Field
The utility model relates to a hydraulic breaking hammer equipment technical field, concretely relates to quartering hammer entire body bolt with gear rubber sleeve.
Background
Along with the accelerated development of domestic capital construction projects, various devices for removing dangerous houses or breaking roadbeds are available, the hydraulic breaking hammer is used as an important mechanical device for breaking and dismantling the road surface in the road engineering construction, is popularized to the building engineering, the hydraulic breaking hammer generally comprises a front cylinder body, a middle cylinder body, a rear cylinder body, a through bolt, a reversing valve, a piston assembly, a hydraulic assembly and other main parts, the existing three-part cylinder body is usually locked by nuts after four through bolts are connected in series, and is influenced by the vibration of the hydraulic breaking hammer, certain radial decomposition impact force collision exists among the through bolts, the lower cylinder body, the middle cylinder body and the upper cylinder body in the radial direction, because the through bolt and the lower cylinder body, the middle cylinder body and the upper cylinder body are all made of metal, the through bolt is easy to break and damage under the long-term high-frequency fatigue collision of the through bolt and the three cylinder bodies, and the service life of the through bolt is greatly shortened.
The improvement of current hydraulic breaking hammer to whole body bolt shock attenuation technique, it establishes cover sleeve type shock attenuation cover mostly to lead to the body bolt periphery cover, and when the through-hole shaft hole cooperation with the triplex cylinder body, interference fit's problem obviously can appear in the insertion process, and it is very inconvenient to install, if lead to the body bolt and can not play sufficient shock attenuation effect again with through-hole clearance fit, both can not get with convenient installation visible effective shock attenuation, need further improve the shock attenuation design again.
Disclosure of Invention
The utility model discloses the purpose: in order to solve the problems in the background art, the breaking hammer through-body bolt with the gear rubber sleeve is designed and provided, the gear rubber sleeve with the damping effect is in contact with the inner wall of the through hole in a line contact replacing surface contact mode, the damping structure of the existing through-body bolt is improved, the breaking hammer through-body bolt can be conveniently and fast installed in the through hole between the lower cylinder body and the upper cylinder body, the collision of the through-body bolt with the radial impact force existing between the lower cylinder body and the upper cylinder body can also be reduced, the damping is sufficient, and the practicability is high.
The technical scheme adopted for solving the problems is as follows:
the utility model provides a quartering hammer entire body bolt with gear rubber sleeve, includes the entire body bolt body, its both ends are equipped with the screw thread section, and the mid portion is provided with a plurality of bulge loop with the through-hole inner wall clearance fit that the lower cylinder body, well cylinder body and the last cylinder body of quartering hammer all were equipped with, bulge loop outer lane cover is equipped with gear rubber sleeve, the gear rubber sleeve is transversal personally submits the gear form, and the periphery evenly is equipped with the rack, rack and through-hole inner wall interference fit.
Furthermore, the inner wall of the central hole of the gear rubber sleeve is provided with a positioning ring which is matched with an annular groove arranged at a position corresponding to the outer ring of the convex ring, and the positioning ring and the convex ring are positioned after being tightly assembled by utilizing the elastic property of the material of the gear rubber sleeve.
Furthermore, the thread sections at the two ends of the through bolt are in threaded connection with the nut to lock the lower cylinder body, the middle cylinder body and the upper cylinder body of the breaking hammer.
The utility model has the advantages that:
this quartering hammer entire body bolt with gear rubber sleeve will play the cushioning effect gear rubber sleeve replaces face contact mode and through-hole inner wall contact with the line contact, extrusion force when gear rubber sleeve's rack and through-hole cooperate, compare in full circle cover sleeve type rubber pad and have simple to operate's advantage, accomplished and conveniently installed down the cylinder body, in the through-hole between well cylinder body and the last cylinder body, also can play the collision of the decomposition impact force that entire body bolt and lower cylinder body, radially exist between well cylinder body and the last cylinder body, the life of extension entire body bolt, therefore, the clothes hanger is strong in practicability.
