Abstract
The invention relates to the field of power system hot-line work insulation ladders, and particularly relates to an insulation ladder tail anti-skid fixer which is characterized by comprising a ladder foot connecting seat, a fixing needle and an impact cap, wherein the impact cap is arranged at the top of the fixing needle, one end of the ladder foot connecting seat is hinged to the impact cap, a pedal handle perpendicular to the fixing needle is arranged on the fixing needle below the impact cap, and the fixing needle and the pedal handle adopt an integrated structure. A connecting sleeve with a rectangular cross section is arranged at the other end of the ladder foot connecting seat, the connecting sleeve is matched with a herring bone ladder foot in dimension, the depth of the socket hole in the connecting sleeve is no less than 100 mm, and a penetrating bolt hole is formed in the connecting sleeve. A connecting post with a circular cross section is arranged at the other end of the ladder foot connecting seat, the connecting post is matched with a hook ladder foot in dimension, and the length of the splice section of the connecting post is no less than 60 mm. Compared with the prior art, the insulation ladder tail anti-skid fixer has the advantages that limitations from seasons do not exist, the insulation ladder tail anti-skid fixer is suitable for various grounds, and a well assembled ladder body can be hoisted and dropped reliably.
Description
Technical field
The present invention relates to the power system livewire work and use the insulating ladder field, relate in particular to the anti-skidding fixator of a kind of insulating ladder tail.
Background technology
When the power system livewire work, often need use insulating ladder, insulating ladder is divided into hanging ladder and double ladder.Since the built on stilts bus of 220kV transformer station to ground level all between 9～11.5m, when carrying out that charged disconnecting is drawn or when pacifying the dismounting static contact, insulation combination hanging ladder, the superelevation double ladders etc. of adopting are built operating platform more, climb up and down and the instrument transmission to realize the equipotential personnel, and then the task that fulfils assignment.
But in real work, weather conditions difference throughout the year, the operation field environment in 220kV equipment place, condition are also different, high hanging ladder more than 10 meters and double ladder are after the assembling of ground, because longer dimension, in the whole ladder lifting of insulating ladder or the dropping process, terraced tail slides, the play amplitude is bigger, the fixed form that the ground electrician steps on by pin is difficult to control, can not satisfy the requirement of rising and falling of operation field insulating ladder.When the control of terraced tail not at that time, the whole terraced play of as easy as rolling off a log appearance and the ladder that falls are pounded the equipment that decreases contiguous operation, cause the generation of bus obstacle, personal injury and equipment breakdown.
Summary of the invention
The purpose of this invention is to provide the anti-skidding fixator of a kind of insulating ladder tail, overcome the deficiencies in the prior art, abandon the backward fixed form that pin is stepped on, satisfy 220kV device context insulation combination hanging ladder, superelevation double ladder in the various ground requirements of rising and falling, be not subject to seasonal restrictions, easy installation and removal, swift to operate.
For achieving the above object, the present invention adopts following technical scheme to realize:
The anti-skidding fixator of insulating ladder tail, comprise foot of ladder Connection Block, locking pin and impact cap, the top of locking pin is provided with impact cap, and an end and the impact cap of foot of ladder Connection Block are hinged, the locking pin of impact cap below is provided with the foot-operated handle perpendicular to locking pin, and locking pin and foot-operated handle are integral structure.
The other end of described foot of ladder Connection Block is provided with the adapter sleeve that the cross section is rectangle, adapter sleeve size and double ladder foot of ladder size coupling, and the socket joint hole depth on the adapter sleeve is no less than 100mm, and adapter sleeve is provided with the bolt hole that runs through.
The other end of described foot of ladder Connection Block is provided with the cross section and is circular joint pin, joint pin size and hanging ladder foot of ladder size coupling, and the inserting section length of joint pin is no less than 100mm, and joint pin is provided with the bolt hole that runs through.
Compared with prior art, the invention has the beneficial effects as follows: be not subject to seasonal restrictions, be applicable to various surface states, can satisfy the use that hanging ladders and superelevation double ladder are made up in various insulation in the 220kV maintenance of equipment scene, the ladder tail need not Field Force's pin, and to step on control fixing, can reliably the terraced body that assembles be risen and fall, easy installation and removal, swift to operate.

The specific embodiment
Below in conjunction with accompanying drawing one step of the specific embodiment of the present invention is illustrated:
See Fig. 1, it is anti-skidding fixator embodiment one structural representation of insulating ladder tail of the present invention, comprise foot of ladder Connection Block 1, locking pin 2 and impact cap 3, the top of locking pin 2 is provided with impact cap 3, one end of foot of ladder Connection Block 1 is hinged by bolt 4 and impact cap 3, the locking pin 2 of impact cap 3 belows is provided with the foot-operated handle 5 perpendicular to locking pin, and locking pin 2 and foot-operated handle 5 are integral structure.Foot of ladder Connection Block 1 can be around bolt 4 at 180 ° of scope intrinsic deflections.
1 other end of foot of ladder Connection Block is provided with the adapter sleeve 6 that the cross section is rectangle, adapter sleeve size and double ladder foot of ladder size coupling, and the socket joint hole depth on the adapter sleeve is no less than 100mm, and adapter sleeve is provided with the locating hole 7 that runs through, and is used for installing alignment pin.
See Fig. 2, be anti-skidding fixator embodiment two structural representations of insulating ladder tail of the present invention, the other end of foot of ladder Connection Block 1 is provided with the cross section and is circular joint pin 8, joint pin 8 sizes and hanging ladder foot of ladder size coupling, the inserting section length of joint pin 8 is no less than 100mm, and joint pin 8 is provided with the locating hole that alignment pin is installed.
During use, foot of ladder with fixator of the present invention and insulating ladder links together earlier, and fix with alignment pin, can carry out the assembling of insulating ladder by normal procedure then, after assembling is finished with the flat operating location of lifting to of insulating ladder, before terraced body rises, locking pin with fixator turns to ground earlier, when ground is hard, impact the top of impact cap with hammer, up to all hammering into locking pin underground; Soft as ground, the foot-operated handle that can directly tramp with one's feet is up to all hammering into locking pin underground; Treat to carry out after corresponding foot of ladder all is connected firmly with ground a liter ladder operation.
