Abstract
The utility model discloses a hydraulic support shaft blocking device, which comprises a pair of clamping plates arranged on a hydraulic support shell, wherein the clamping plates are positioned at the left side and the right side of the extending end of a pin shaft at the position of a base body, vertical clamping grooves with L-shaped cross sections are symmetrically arranged on the opposite surfaces of the clamping plates, a shaft blocking plate positioned at the outer side of the pin shaft at the position of the base body is clamped at the inner side of each vertical clamping groove, the left side and the right side of the shaft blocking plate are stepped surfaces matched with the vertical clamping grooves, and the outer surface of the shaft blocking plate is flush with the outer surface of the clamping; the top of the baffle shaft plate is connected with the hydraulic support shell through a bolt, and the bolt is connected with the baffle shaft plate through a U-shaped clamp which is transversely penetrated; and a limiting plate fixedly connected on the hydraulic support shell is arranged at the bottom of the baffle shaft plate. The utility model discloses simple structure, low cost has protected the round pin axle not influenced by external force effectively, has avoided because the frame that moves causes the phenomenon that adjacent support can not normally work, has improved work efficiency effectively.
Description
Technical Field
The utility model belongs to the technical field of the hydraulic support technique and specifically relates to a hydraulic support keeps off axle device is related to.
Background
In order to maintain stability, the existing slow-tilting hydraulic support and the existing fast-tilting hydraulic support are both provided with bottom adjusting devices, and when the supports are moved, the bottom adjusting devices can be stretched out to adjust postures. Under the normal condition, the hydraulic supports are arranged at the position of a coal face in rows, when the bottom adjusting device is extended out by the support of the advance moving frame, the hydraulic supports easily act on the pin shafts at the position of the base bodies of the adjacent supports, so that the pin shafts of the adjacent supports are jacked off, the adjacent supports cannot normally work, and the smooth operation of the whole coal face is influenced.
Disclosure of Invention
In order to solve the problem, the utility model provides a hydraulic support keeps off axle device can take following technical scheme:
the hydraulic support shaft blocking device comprises a pair of clamping plates arranged on a hydraulic support shell, wherein the clamping plates are positioned on the left side and the right side of the extending end of a pin shaft at the position of a base body, vertical clamping grooves with L-shaped cross sections are symmetrically arranged on opposite surfaces of the clamping plates, a shaft blocking plate positioned outside the pin shaft at the position of the base body is clamped on the inner side of each vertical clamping groove, the left side and the right side of the shaft blocking plate are stepped surfaces matched with the vertical clamping grooves, and the outer surface of the shaft blocking plate is flush with the outer surface of the clamping plates; the top of the baffle shaft plate is connected with the hydraulic support shell through a bolt, and the bolt is connected with the baffle shaft plate through a U-shaped clamp which is transversely penetrated; and a limiting plate fixedly connected on the hydraulic support shell is arranged at the bottom of the baffle shaft plate.
The top of the clamping plate extends to form a rectangular connecting sheet, and the rectangular connecting sheet is provided with a bolt hole and a U-shaped clamping hole which are perpendicular to each other.
The utility model provides a hydraulic support keeps off axle device, simple structure, low cost, safe and reliable, easy dismounting, it is through setting up the fender axial plate that clamps the structure in the round pin outside of axle, has protected the round pin axle not influenced by external force effectively, has avoided because moving the phenomenon that the frame caused adjacent support can not normally work, has guaranteed the smooth operation of whole coal face, has improved work efficiency effectively.
