The size and active force of the various components such as shaft tower, fitting and insulator certainly will be influenced.By taking porcelain insulator as an example, it can hold
The maximum pull received progressively increases to 550kN from 200kN and is even as high as 840kN.
The raising of insulator maximum pull, so that the size and the weight of itself of insulation sub-volume are also being continuously increased.Than
Such as in 1000kV voltage class, the monomer weight of porcelain insulator reaches nearly 30 kilograms, moves closer to staff in high-altitude
The middle physical endurance that can carry weight weight, and the work for replacing insulator is usually carried out continuously within one day, operation
Personnel need to consume a large amount of physical strength.Therefore, in working at the scene, it is contemplated that the actual conditions of service personnel, originally in low-voltage
In grade using the Work tool of replacement insulator and method in the super of large-tonnage insulator, UHV transmission line gradually
It can not be applicable in.
In order to meet needs that are super, replacing insulator work in UHV transmission line, need to develop a kind of completely new novel
Detachable bracket large-tonnage insulator fixture enables new, the old insulator of operation field to carry out in a manner of a kind of most labour-saving
Lifting, and it can be directly elevated to the position needed replacing, remove operating personnel's heavy physical labor from.Meanwhile because route is examined
Mostly single-point operation is repaired, personnel amount is few, and needs continuous special show, therefore it is required that this Work tool has structure simple, small in size, again
Measure the features such as light, easy to operate.
The purpose of the utility model is to provide a kind of suitable for super, UHV transmission line removable for utility model content
Bracket large-tonnage insulator fixture is unloaded, new, old insulator can be gone up and down in a manner of a kind of most labour-saving, and can be straight
The position for being elevated to and needing replacing is connect, operating personnel is significantly reduced in high-altitude and holds the time of insulator, mitigate operation people
The heavy physical demands of member, and require platform structure it is simple, it is small in size, light-weight, easy to operate, be easy to dismount.
In order to achieve the above object, the technology employed by the present utility model is
A kind of detachable bracket large-tonnage insulator fixture, it is characterised in that: including two symmetrical parallel machinery
Lead screw, Screw assembly has connector, two mechanical lead screw axial forward ends respectively for axial forward end, the axial rearward end of each machinery lead screw
Connector on the inside of between be connected with preceding closed fixture, on the inside of the connector of two mechanical lead screw axial rearward ends between be connected with after close
Formula card, between two connection cephalic pars of axial forward end, to be connected separately with herringbone oblique between two connection cephalic pars of axial rearward end
Side bracket is connected with crossbeam between the herringbone vertex of the herringbone bevel edge bracket of forward and backward side, coaster is equipped on crossbeam, sliding
Liftable pulley is mounted on vehicle.
A kind of detachable bracket large-tonnage insulator fixture, it is characterised in that: solid among each machinery lead screw
Surely it is connected with mechanical lead screw handle.
A kind of detachable bracket large-tonnage insulator fixture, it is characterised in that: on the crossbeam along the longitudinal direction
Equipped with multiple carry holes, the coaster energy carry is in any one carry hole.
The utility model include: herringbone bevel edge bracket, connector, mechanical lead screw, mechanical lead screw handle, preceding closed fixture,
Closed fixture, crossbeam, coaster and pulley afterwards:
The utility model integrally uses aluminium alloy to be made for material.It is herringbone bevel edge branch on the outside of forward and backward closed fixture
Frame, forward and backward closed fixture inside are mechanical lead screw.It is connected between closed fixture, bevel edge bracket and mechanical lead screw with connector, mechanical silk
Thick stick is fastened by mechanical lead screw handle.
Crossbeam is installed on the upside of herringbone bevel edge bracket, carries out round punching according to certain equidistant interval among crossbeam,
Coaster is facilitated to carry out carry.
Coaster one end carry is in the equidistant circular hole of crossbeam, and specific location can be adjusted with used circular hole, the other end
Carry pulley, to go up and down insulator.
The beneficial effects of the utility model are:
Novel dismountable bracket large-tonnage insulator fixture provided by the utility model passes through forward and backward closed fixture when operation
And this Work tool is firmly fixed in insulator chain by mechanical lead screw.Since the size of closed fixture and lead screw is adjustable and more
It changes, therefore the replacing insulator work of arbitrary dimension can be met.Insulator is gone up and down by the coaster on crossbeam, eliminates work
The a large amount of manual labor of industry personnel, so that replacement insulator work becomes more light, easy.The position of coaster can pass through cross
Circular hole on beam is adjusted, and guarantees that it can facilitate the lifting of insulator in the top of insulator.
The utility model mainly uses aluminium alloy to be made for material, so that platform overall weight is lighter.Entire work device
Although it is more to have components, it is all made of the modes such as latch closure, screw and connects, be dismounted easily.The whole size of job platform and portion
Divide the size of components can specifically be adjusted according to on-site actual situations, can accomplish seamless interfacing, be had very strong logical
The property used.
