Description
Technical field
The utility model relates to oil cylinder, particularly a kind of jaws locking cylinder cylinder sleeve draw-off gear.
Background technology
At present in metallurgical works maintenance of equipment process, the inner cylinder sleeve of various kinds of equipment needs periodic replacement owing to wearing and tearing, owing to there is no specific purpose tool in actual job process, there is the situation of inconvenient dismounting, scene only used the light instruments such as screwdriver to carry out operation in the past, not only efficiency is low but also dismounting difficult quality is guaranteed, and finds that original technique has following three defects by field investigation:
1) position at oil cylinder cylinder sleeve place causes conventional tool to use, and operating efficiency is low.
2) the dismounting mode of cylinder sleeve is unreasonable, easily causes cylinder body self-inflicted injury, reduces its service life.
3) original technique easily causes inboard wall of cylinder block to there will be big and small burr after removing, and causes certain difficulty to the new cylinder sleeve of installation, needs first to polish to it, takes time and effort.
Summary of the invention
The purpose of this utility model is to design a kind of jaws locking cylinder cylinder sleeve draw-off gear, can improve field-strip efficiency and the assembly precision of cylinder sleeve.
For achieving the above object, the technical solution of the utility model is:
A kind of jaws locking cylinder cylinder sleeve draw-off gear, it comprises, the threaded push rod in bottom, and spanner is established on push rod top; Adjusting nut, is sheathed on described push rod bottom; Expand an ancient unit of weight nut, be sheathed on described push rod bottom, under being positioned at adjusting nut; Drag hook cover, is sheathed on described push rod bottom, is positioned under expanding an ancient unit of weight nut, and drag hook cover center through hole two side symmetry offers limited impression; Drag hook seat, in inverted T-shaped, comprise the pedestal that is positioned at bottom and on body, this pedestal is circular, and bilateral symmetry offers fixed groove; Described body is sheathed on described push rod bottom, and is arranged in drag hook cover, expands in an ancient unit of weight nut, adjusting nut, and with drag hook cover, expand an ancient unit of weight nut, adjusting nut threaded engagement; Two drag hooks, are arranged in the fixed groove of described drag hook seat both sides respectively, and are movably connected in the fixed groove of drag hook seat both sides by connecting pin, and two drag hook upper-end part of drivings are in the both sides limited impression that drag hook overlaps; One spring, two ends connect two drag hook bottoms.
Further, described expansion an ancient unit of weight nut, adjusting nut lateral wall establish the jack planted for adjusting rod.
In addition, the bottom of described two drag hooks is also offered and is installed through hole and connecting pin, and this two connecting pin is located at by described both ends of the spring hook.
Described adjusting nut and drag hook seat body offer locking counterbore and a screw in conjunction with end face.
During use, drawbench is goed deep into cylinder sleeve inside, aim at cylinder sleeve inside groove with two hooks, rotating adjusting nut makes hook catch on cylinder sleeve inside groove, then rotates push rod handle, now, push rod protracts, and withstands equipment inner wall, under the effect of reaction force, cylinder sleeve is ejected block set, realizes removing object.
The beneficial effects of the utility model:
After the utility model comes into operation, need to drop into operation number during single operation and drop to 1 people from 2 original people; Activity duration drops to each 15min from original 2h, and ensures that installation quality has saved a large amount of activity duration objectively.Annual financial cost of saving reaches 10.2 ten thousand, and its operability and security also obtain huge lifting.
