Abstract

The utility model discloses a device for moving along a tensile tower insulator string on an ultrahigh voltage line. The device comprises a support frame, a handle and a pedal, wherein the end head of the support frame blocks the bowl head of an insulator, two ends of the support frame are sleeved by using glue sleeves, the handle and a pedal are arranged on the support frame, and a buckling rope is arranged on the pedal. According to the device for moving along the tensile tower insulator string on the ultrahigh voltage line, after the support frame blocks the bowl head of the insulator, the operation personnel can maintain balance during standing on a moving device in a process of operating the insulator string without shaking, thus the convenience is brought for the personnel to carry out insulator salt density acquisition, insulator sweeping, insulator inspection, equipotential accessing and the like on the ultrahigh voltage line; and the device has the advantages of being convenient and simple in operation, lightening labor intensity and operation difficulty of operations, and increasing operation safety and efficiency.

Description

At extra high voltage line along the device that moves on the strain tower insulator string

One, technical field

The utility model relate to a kind of at extra high voltage line along the device that moves on the strain tower insulator string, be applicable to the upkeep operation on the strain insulator string of wide spacing, long distance.

Two, background technology

At present; Increase day by day along with the China Power demand; At a distance, big capacity, EHV transmission have become the leading of electric power epoch; Along with putting into operation of UHV transmission line, original 500kV transmission line operation mode can not satisfy the demand of Maintenance of Electric Transmission Line, maintenance on the extra high voltage line strain insulator string of wide spacing, long distance.In the prior art, a kind of method is that operating personnel's both feet step down on the insulator string bowl head, and both hands are caught another insulator string bowl head, slowly move to job position; A kind of is to adopt a wooden stick horizontal on two insulator string bowl heads, and people's both feet step down on the insulator string bowl head, holds the bowl head in hand for one of the people, and another holds wooden stick, slowly moves to job position.

Implement said method and have following difficulty

1,,,, thereby causes the accident generation easily with loss operating personnel's muscle power greatly if the operating personnel stays on the insulator string for a long time because spacing broad (1.1m), the length of extra high voltage line strain tower insulator string grow (13m).

2, the operating personnel adopts said method on insulator string, to carry out operation, and can not insulate close collection of alite and insulator more change jobs, and operating efficiency is low.

Three, summary of the invention

For solving the problems referred to above of prior art; The purpose of the utility model provide a kind of at extra high voltage line along the device that moves on the strain tower insulator string; Can assist the work high above the ground personnel on the strain insulator string of wide spacing, long distance, to accomplish the mobile servicing unit of upkeep operations such as the monolithic insulator is changed, insulator cleaning, the close collection of insulation alite; Alleviate work high above the ground personnel's labour intensity and task difficulty; Increase work efficiency, guarantee that simultaneously the work high above the ground personnel are in the upkeep operation process safe.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of at extra high voltage line along the device that moves on the strain tower insulator string; Form by bracing frame, handle and pedal; Insulator bowl head is blocked in the termination of support frame as described above; Entangle with gum cover at the bracing frame two ends, and bracing frame is provided with handle and pedal, and pedal is provided with buckles rope.

The operation principle and the process of said device are:

1, the work high above the ground personnel are self-contained or adopt to transmit rope and be passed to ultra high voltage strain tower tower head end place; The work high above the ground personnel are placed on firm place to mobile device; And the bracing frame card that makes mobile device is surely on insulator bowl head, thereby mobile device is not rocked back and forth, and reaches firm purpose.

2, after installing one of them mobile device, the work high above the ground personnel step down on the pedal of device.Through pedal the operating personnel is well stood, and can vacate both hands and on insulator, carry out each item work.

When 3, on insulator string, moving, the operating personnel must do a good job of it the handle of device, and pin and hand slightly firmly just can move simultaneously.

The technique effect that the utility model reaches:

1, said mobile device, as the Work tool of operation on strain insulator string, its security performance satisfies the requirement of electric power safety working regulation, can effectively improve the coefficient of safety of work high above the ground personnel when overhauling.

2, use mobile device operation on insulator string, can safety, efficiently finish the work, increase work efficiency, alleviate operating personnel's labour intensity.

3, adopt the aluminum alloy materials casting, single deadweight 2kg, rated load 200 kg carry out 2.5 times of running tests, do not have distortion and damage, and mechanical strength meets electric power Work tool general technical specifications standard.

4, can on insulator string, accomplish operations such as insulator cleaning and the close collection of salt fast by mobile device.

Five, embodiment

Below through accompanying drawing and embodiment the technical scheme of the utility model is further described.

Map 1 is to Fig. 3; The utility model described at extra high voltage line along the device that moves on the strain tower insulator string; Be made up of bracing frame, handle and pedal, insulator bowl head is blocked in the termination 1,2 of support frame as described above, and entangle with gum cover 3 at the bracing frame two ends; Bracing frame is provided with handle 4 and pedal 5, and pedal 5 is provided with buckles rope 6.

Its course of work and principle are:

As shown in Figure 1, insulator bowl head is blocked in bracing frame termination 1,2, thereby can fix bracing frame, is beneficial to personnel's work.

Entangle with gum cover 3 at the bracing frame two ends, and the frictional force in the time of can increasing bracing frame and contact with insulator bowl head prevents to slide before and after the bracing frame.

Bracing frame is provided with handle 4, and its effect is to make operating personnel's convenient bracing frame that moves when crossing insulator string.

Bracing frame is provided with pedal 5, and purpose is that the convenient working personnel stand on the bracing frame.

Pedal 5 is provided with buckles rope 6, is used to entangle operating personnel's pin, when the mobile operating device, is beneficial to the stressed bracing frame of mentioning of operating personnel simultaneously.

The concrete operation method step is following:

1, the work high above the ground personnel are self-contained or adopt to transmit rope and be passed to ultra high voltage strain tower tower head end place, and the work high above the ground personnel are placed on firm place to mobile device, and the bracing frame 1 of mobile device is blocked surely on insulator bowl head with 2.

2, after installing one of them mobile device, the work high above the ground personnel step down on the pedal 5 of device, and buckle well pedal and buckle rope 6.Through pedal 5 operating personnel is well stood, and can vacate both hands and on insulator, carry out each item work.

When 3, on insulator string, moving, the operating personnel must do a good job of it the handle 4 of device, and pin and hand slightly firmly just can move simultaneously, thereby can arrive setting quickly.
