Abstract

The utility model discloses an electrified overhauling wrench which comprises a first insulating draw bar, a first support, an upper sleeve head, a second insulating draw bar, a second support and a lower sleeve head, wherein the first insulating draw bar is used for preventing a bolt from rotating, and the second insulating draw bar is used for tightening the bolt. The first insulating draw bar and the first support, and the second insulating draw bar and the second support are fixed by welding. The second support and the first support are movably connected by a sleeve pipe of the first support in a sleeved mode. The first support and the upper sleeve head, and the second support and the lower sleeve head are movably connected. The electrified overhauling wrench has the advantages of being capable of freely adjusting the length of the first insulating draw bar and the second insulating draw bar, and achieving overhauling of electric power circuits of different heights. Overhauling personnel can operate on the ground and do not ascend, so that overhauling safety and overhauling efficiency are improved. When overhauling is conducted, outage is not required, power supply reliability is improved, and economic benefits of an electric enterprise are effectively maintained. The electrified overhauling wrench is simple in whole structure, and convenient to dismantle, assemble and carry.

Description

The hotline maintenance spanner
Technical field
The utility model relates to a kind of hotline maintenance spanner, is applicable to power system service technique field.
Background technology
At present, the overhead transmission line of department of State Grid often needs to overhaul after using a period of time, such as becoming flexible of 110-220KV transforming plant primary equipment (switch, CT, PT lead-in wire etc.), will cause the circuit heating, the detonator circuit fault affects the normal productive life of people easily.Cause the loosening reason of primary equipment to mainly contain: the contact-making surface oxidation; The excessive lead-in wire of wind-force waves; Bolt is of poor quality; Ply-yarn drill is of poor quality.These failure causes often occur in peak times of power consumption in summer, and accident is in case occur, and need at once interruption maintenance to process, and take a 110KV line outage 2 hours as example, the loss of outage that every processing primary fault causes is about 30,000 KWh.For the maintenance of power equipment, at present general instrument mainly contains for the maintenance spanner of fastening bolt etc., and existing maintenance spanner all is conductive material, needs interruption maintenance; Existing maintenance spanner needs the maintainer to ascend a height near power equipment in addition, just can overhaul, and efficient is low, and security reliability is poor.Therefore, in the urgent need to a kind of maintenance spanner of can charged use and need not ascend a height.
The utility model content
Technical problem to be solved in the utility model provides a kind of hotline maintenance spanner that can carry out on ground hot line job, and is simple in structure, easy to carry, improves overhaul efficiency.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of hotline maintenance spanner, comprise be used to the first insulated tension pole, the first support and upper pullover that prevent that bolt from rotating, and the second insulated tension pole, the second support and lower pullover that are used for fastening bolt; Between described the first insulated tension pole and the first support, between the second insulated tension pole and the second support all by being welded and fixed; Pass through the sleeve pipe pivot bush unit on the first support between described the second support and the first support; Described the first support and upper pullover between, the second support and lower all be to be flexibly connected between pullover.
Described the first support and upward be flexibly connected square joint and the first support welding, upper pullover and square joint clamping by square joint between pullover; Described the second support and be flexibly connected square joint and the second support welding, lower pullover and square joint clamping by square joint between pullover down.
The course of work of using hotline maintenance spanner described in the utility model to carry out hotline maintenance is as follows: (1) is the fastening or bolt model changed as required, select suitable corresponding pullover and lower pullover, and with upper pullover being installed on the first support, with lower pullover being installed on the second support; (2) hand-held the first insulated tension pole of maintainer with upper pullover top near bolt to be tightened, and maintains static; (3) maintainer regulates the wrench opening size according to the bolt size, then operates the bottom that the second insulated tension pole makes the nearly bolt to be tightened of head rest of trapping; (4) rotating the second insulated tension pole carries out bolt fastening or dismounting.
The beneficial effect that adopts technique scheme to produce is:
(1) be installed on the insulating bar by support bolt is pullover, length that can the free adjustment insulating bar realizes the maintenance of differing heights power circuit bolt, and the maintainer just can operate on ground, need not ascend a height, and improves the security and the overhaul efficiency that overhaul;
(2) because the maintainer operates by insulating bar, when service work is carried out, can have a power failure, improve power supply reliability, effectively safeguard the economic interests of electric power enterprise;
(3) since maintenance spanner each several part be flexibly connected, simple in structure, be convenient to dismounting and carry.
