Description
Technical field
The utility model relates to a kind of electric power overhaul instrument, particularly relates to a kind of insulator locking pin pin removal.
Background technology
In power transmission lines overhauling, insulator locking pin (the being mainly R type pin) pin pulling tool used at present mainly contains vice, self-control sled hooks.Can only the R type pin of upluging part insulator with vice; Self-control sled hooks and firmly needs different change action point, and easily wearing and tearing R sells zinc coat, and pole expends bodily strength.Moreover two kinds of instruments are all rectilinear form, when pulling out anti-pollution type insulator locking pin, the space of operation of not pulling pin, very easily smashes glass insulator in process of choosing, and changes Defile-proof for Electric Transmitting Line type insulator and there is certain difficulty.Along with self-destruction insulator quantity is increasing, the problem how can changing self-destruction pollution proof insulator in maintainer's limited strength situation more fast, effectively, safely becomes increasingly conspicuous.Part locking pin cannot be extracted smoothly, have impact on the efficiency changing insulator, in the urgent need to developing a kind of novel pin pulling tool.
The mode of pulling pin used at present often has: R type pin use tiger clamp to go out or with self-control sled hook prized loosening after extract.There is following problem in these two kinds traditional modes of pulling pin: (1), in R type pin withdrawal process, the mode of clamp can cause the zinc coat on locking pin surface to sustain damage, and anti-corrosion capability declines, and its useful life is reduced.(2) when choosing locking pin, need constantly conversion stress point position and Impact direction, elapsed time is longer, R can be caused simultaneously to sell and loosen distortion; (3) because locking pin covers by anti-pollution type insulator large shirt rim completely, these traditional two kinds of instruments are easily blocked by shirt rim when operating, and lack operating space, operate by force and easily cause insulator to be broken up.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of can be extracted by insulator locking pin fast and the minimum insulator rotation of labour intensity pushes away formula pin removal.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of insulator rotation pushes away formula pin removal, comprise lifting-hook shape to pull pin hook, the vertical section of described hook of pulling pin is fixedly connected with vertical screw shell, thrust screw rod with matching is connected with in described vertical screw shell, the outer movable sleeve of described vertical screw shell is connected to inverted L shape support, described inverted L shape support can along vertical screw shell axially lower slider, and the upper end of described thrust screw rod is provided with rotary handle.A kind of insulator rotation of the utility model pushes away formula pin removal, vertical screw shell can be made to drive hook of pulling pin to produce displacement straight up by rotary thrust screw rod, be placed on locking pin side hook of can effectively avoiding pulling pin tilt by inverted L shape is propped up simultaneously, thus ensure that locking pin is subject to withdrawal force vertically upward, so both be convenient to extract locking pin fast, greatly reduced again operation labour intensity.
As preferably, described inverted L shape support is connected with vertical screw shell by the bracket sleeve tube be sleeved on outside vertical screw shell, be matched in clearance between described bracket sleeve tube and vertical screw shell, inverted L shape support and vertical screw shell is connected by bracket sleeve tube, both be convenient to processing and manufacturing, and be easy to again ensure its upper and lower relative sliding.
As preferably, the outer surface of described vertical screw shell is vertically provided with a rectangle plane, bracket sleeve tube inner surface is also provided with the plane matched with vertical screw shell, described pull pin hook and inverted L shape support are positioned at the same perpendicular of vertical screw shell homonymy, by by the mating surface of bracket sleeve tube and vertical screw shell wherein one section be designed to plane, inverted L shape support can be avoided like this to rotate to ensure its support force, and the rectangle plane in addition on vertical screw shell is convenient to again connect in its lower end hook of pulling pin.
As preferably, described in the pull pin vertical section of hook and vertical screw shell be welded to connect, hook of pulling pin is welded on the rectangle plane on vertical screw shell, connects very firm.
Compared with prior art, a kind of insulator of the utility model rotates the beneficial effect pushing away formula pin removal: by thrust screw rod and inverted L shape supporting structure, withdrawal force straight up can be imposed to locking pin accurately, thus realize easily rapidly locking pin being extracted from insulator bowl head.The utility model causes for the large shirt rim of pollution proof insulator and pulls pin narrow space and affect the problem of R type locking pin of choosing, and devises and utilizes the application point of power, the conversion of type of action, can use rotation thrust outside shirt rim, push away out R type locking pin.Rotation is used to push away formula pin removal and carry out operation of pulling pin, the position of exerting oneself when successful transformation is pulled pin, more laborsaving, convenient, rapidly locking pin is extracted; Change original clamp to pull pin mode simultaneously, reduce the damage to R type pin.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
