Abstract

The invention provides a hanger frame of a fixed-steering pulley. The hanger frame comprises a hanger beam (8), a steering pulley and two groups of bracket assemblies (2). The bracket assemblies (2) are fixed to two sides of the lantern ring of a closed fixture (1) for replacing a single insulator respectively through connection screws (3) by two ends of a fork-shaped bracket, and then the two brackets are connected to the hanger beam (8). The steering pulley is connected to the hanger beam (8) between the two brackets. The steering pulley is formed by a pulley (6), a pulley frame (4) and a connection fork ear (5) connected to the pulley frame (4). The connection fork ear (5) is connected to the hanger beam (8) through a bolt. Adjusting holes are uniformly distributed in horizontal rows on the body of the hanger beam (8). One end of the hanger beam (8) is provided with a long groove for adjusting the connection between the hanger beam and the bracket assemblies (2) according to the different numbers and different distances of front and back insulators clamped by the closed fixture (1). The hanger frame has the advantages of convenient operation and high safety and stability.

Description

A kind of suspension bracket of fixing corner block
Technical field the invention belongs to power industry and changes insulator clamp apparatus technical field of structures.
Background technology
Be placed into ground and alternative insulator is hung in the position be removed after utilizing closed type fixture to change monolithic insulator and install, because corner block difficulty is installed in operation place, existing technology is that the insulator of dismounting will be embraced steel cap with embracing bottle card, the insulator of dismounting is put into ground with rope by operator on the insulator string of setting, then replaces with new insulator and be promoted to the insulator position of having removed by operator on tower and install.Due to present increasing along with electric pressure, superhigh pressure or extra high voltage line insulator load increasing, insulator weight is more and more heavier, and when operator promotes insulator, working strength increases, and changes that insulator work is time-consuming, effort, brings potential safety hazard to operation.The lifting that above Problems existing is no longer applicable to when changing insulator is replaced insulator work.
Summary of the invention
For superhigh pressure or extra high voltage line insulator load large, insulator Heavy Weight and superhigh pressure or extra high voltage line insulator string and gold utensil feature, according to working method and the job position of operating personnel on tower during operation, the contents such as replacing insulator are to the switching overvoltage in operation process, the requirement of safe distance and insulator replacement tool, and the correlation technique condition of superhigh pressure or extra-high line ball operation, object of the present invention provides one can adapt to superhigh pressure or extra high voltage line to overcome defect that above-mentioned prior art exists and easy to operate just, suspension bracket fixed by the corner block of safety and stability, be applicable to lifting work when changing monolithic insulator.
Technical scheme
The technical scheme realizing above-mentioned purpose is:
A suspension bracket for fixing corner block, the present invention is characterised in that, comprises hanging beam and corner block and two pack support assemblies; Described bracket component is separately fixed at the closed type fixture collar both sides changing monolithic insulator by attachment screw by the support two ends in fork-shaped, then be connected in respectively on hanging beam by two stands; Corner block to be also connected on hanging beam and between two stands; Described corner block is pitched ear by pulley and pulley yoke and the connection be connected on pulley yoke and is formed, and connection fork ear is bolted on hanging beam; Described hanging beam, horizontally-arrangedly on beam body is laid with adjustment hole; One end of hanging beam is provided with elongated slot, for different according to the sheet number of institute's card insulator before and after closed type fixture, spacing is different and adjust the connection of hanging beam and bracket component.
When changing monolithic insulator work, two stands is separately fixed in the closed fixture front and rear card main body of replacing monolithic insulator, with attachment screw, it is fastening.Hanging beam connected with two stands and fixes, corner block being adjusted to after above insulator to be changed, and connecting with hanging beam.Ropes walks around corner block.One terminal insulator, it is to be hoisted that the other end places ground.Tighten up closed fixture leading screw, after insulator string is lax, remove the insulator that will change with and be linked with ropes, the lifting work of monolithic insulator replacing can be carried out.
Beneficial effect
It is few that suspension bracket of the present invention has connector, and connect simple during work, efficiency is high, is converted to rolling friction lifting insulator by originally directly promoting insulator with operator.Hanging beam main body one end is designed with elongated slot, can different according to the sheet number of main body institute card insulator before and after closed type fixture, spacing is different and adjust; So suspension bracket of the present invention is a kind of Multifunctional suspension bracket.Suspension bracket of the present invention has easy to operate, safety and stability, promotes the work of monolithic insulator when being well suited for changing monolithic insulator.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
See Fig. 1-Fig. 5, a kind of suspension bracket of fixing corner block, the present invention is characterised in that, comprises hanging beam 8 and corner block and two pack support assemblies 2; Described bracket component 2 is separately fixed at closed type fixture 1 collar both sides changing monolithic insulator by attachment screw 3 by the support two ends in fork-shaped, then be connected in respectively by two stands on hanging beam 8; Corner block to be also connected on hanging beam 8 and between two stands; Described corner block is pitched ear 5 by pulley 6 and pulley yoke 4 and the connection be connected on pulley yoke 4 and is formed, and connection fork ear 5 is bolted on hanging beam 8; Described hanging beam 8, horizontally-arrangedly on beam body is laid with adjustment hole; One end of hanging beam 8 is provided with elongated slot, for different according to the sheet number of institute's card insulator before and after closed type fixture 1, spacing is different and adjust the connection of hanging beam and bracket component 2.
Closed fixture suspension bracket of the present invention be a kind of for changing monolithic insulator time promote the suspension bracket being replaced insulator, pulley yoke 4, connection fork ear 5 and pulley 6 are connected as a single entity, be arranged on the left and right sides of hanging beam 8, composition corner block assembly carries out lifting work as shown in Figure 2, Figure 4 shows.
Two stands assembly 2 is separately fixed in the closed fixture 1 front and rear card main body of replacing monolithic insulator, with attachment screw 3, it is fastening.Hanging beam 8 connected with two stands and fixes, corner block assembly 4,5,6 being adjusted to after above insulator to be changed, and connecting with hanging beam 8.Ropes walks around corner block.One terminal insulator 7, the other end is placed ground and is treated that terrestrial operation person's folding and unfolding promotes.Tighten up closed fixture leading screw, after insulator 7 is lax, remove the insulator that will change and be linked with ropes, operator's folding and unfolding rope can carry out the lifting work of monolithic insulator replacing.
