Abstract

The utility model provides a protection mechanism's unwrapping wire coaster is strideed across to transmission line passageway, install the insulation connecting rod in support roller top opening both sides including support roller and two oscillatings, support roller comprises support roller support and the support spill wheel installed on the support roller support, the oscillating is equipped with the becket bridle in insulation connecting rod's upper end, below at the support roller support is equipped with the tow lug. This unwrapping wire coaster is used for holding up the change cable, makes the transmission line passageway stride across the construction and need not to build crossing structure, has improved the efficiency of construction, has better application prospect.

Description

A kind of electric transmission line channel crosses over the releasing pulley of protection mechanism
Technical field
The utility model relates to a kind of cable construction instrument, especially a kind of releasing pulley crossing over protection mechanism for electric transmission line channel.
Background technology
In construction of cable run, usually needing that replacing is led, ground wire, in order to protect below by leap facility, as power circuit, highway, railway, river, house owed by a citizen etc., usually can take safeguard measure, as: low-voltage transmission of electricity or distribution line, need to have a power failure; No through traffic for road and rail needs.
In the process changing lead wire and earth wire, in order to ensure that the lead wire and earth wire changed toward below landing, can not cause being had an impact by leap facility because of tension force not, crossing frame is set up in usual employing, highly exceed by leap facility, make the lead wire and earth wire of replacing drop in crossing frame, the main instrument adopted is by mao bamboon, iron wire etc., flow process is as follows: the first, before replacing lead wire and earth wire 10 to 15 days, is setting up crossing frame being crossed over the one or both sides of thing, fence is set, and it is on duty to send someone around; The second, when changing lead wire and earth wire, if be power circuit by leap facility, need to apply in advance having a power failure, if highway, need traffic control etc.; 3rd, after changing lead wire and earth wire, remove crossing frame.This kind crosses over resist technology to be needed within 10 to 15 days, to carry out setting up crossing frame in advance; area occupied is large; serious by landform, weather, environmental impact; in addition; because crossed line can not have a power failure simultaneously; be difficult to carry out traffic control by the highway, railway, navigable river etc. crossed over, all will have influence on more changing jobs of lead wire and earth wire.
Summary of the invention
Object to be solved in the utility model is to provide a kind of electric transmission line channel that can realize to cross over the releasing pulley that protection mechanism carry changes cable, prevents from changing cable because of tension force past below landing not.
In order to solve the problems of the technologies described above, the utility model provides a kind of electric transmission line channel and crosses over the releasing pulley of protection mechanism, comprises supporting pulley and two swing types are arranged on the insulated connecting rod supporting pulley upper opening both sides; Support pulley to form by supporting pulley support and being arranged on the support spill wheel supported on pulley support; Becket bridle is provided with at the upper end swing type of insulated connecting rod; Bail is provided with in the below supporting pulley support.
Two insulated connecting rods are adopted can effectively replacing cable and insulated lift rope to be isolated on the one hand, cable is changed in charged situation, and without the need to power cut construction, inverted "eight" shape supporting construction can be formed in work progress on the other hand, effectively suppress releasing pulley at the aerial double swerve of height; Adopt becket bridle that insulated connecting rod can be facilitated to be connected with insulated lift rope, effectively improve the convenience of construction; Adopt bail can conveniently insulate pull rope with support pulley be connected, further increase the convenience of construction.
As further restriction scheme of the present utility model, the upper opening both sides supporting pulley support are tilting articulated respectively by the lower end of hinge and two insulated connecting rods.Adopt chain connection can facilitate swing type fixed insulation connecting rod.
As further restriction scheme of the present utility model, supporting pulley support is U-shaped fork head type structure, and on two jaws, be equipped with a support spill wheel.Adopt the support pulley support of U-shaped fork head type structure, replacing cable can be placed on two and support on spill wheel, effectively improve the steadiness of cable.
The beneficial effects of the utility model are: (1) adopts two insulated connecting rods can effectively replacing cable and insulated lift rope be isolated on the one hand, cable is changed in charged situation, and without the need to power cut construction, inverted "eight" shape supporting construction can be formed in work progress on the other hand, effectively suppress releasing pulley at the aerial double swerve of height; (2) adopt becket bridle that insulated connecting rod can be facilitated to be connected with insulated lift rope, effectively improve the convenience of construction; (3) adopt bail can conveniently insulate pull rope with support pulley be connected, further increase the convenience of construction.

Embodiment
As Figure 1-3, the releasing pulley of electric transmission line channel leap protection mechanism of the present utility model comprises: support pulley and two swing types are arranged on the insulated connecting rod 2 supporting pulley upper opening both sides.
Wherein, support pulley to form by supporting pulley support 1 and being arranged on the support spill wheel 1.1 supported on pulley support 1; Becket bridle 2.1 is provided with at the upper end swing type of insulated connecting rod 2; Bail 1.2 is provided with in the below supporting pulley support 1; The upper opening both sides supporting pulley support 1 are tilting articulated respectively by the lower end of hinge 3 and two insulated connecting rods 2.
As a kind of preferred structure of the present utility model, supporting pulley support 1 is U-shaped fork head type structure, and on two jaws, be equipped with a support spill wheel 1.1.
Releasing pulley of the present utility model comprises the steps: when constructing
(1) after electric transmission line channel is crossed over the carry parts carry of protection mechanism by the operating personnel on tower, Ground Operation personnel utilize two eradication edge halliards to drag two carry parts respectively extremely by by the facility of crossing construction, again the other end of the insulated lift rope on two carry parts is connected firmly with becket bridle 2.1 colligation on the insulated connecting rod 2 of two epoxide resin materials respectively, then with on the bail 1.2 of an one end colligation thoroughly doing away with edge pull rope below releasing pulley;
(2) ground staff pulls the other end of the insulated lift rope on two carry parts simultaneously, observe the mark on insulation pull rope, releasing pulley is increased to ensure with below safe distance height, adjust the stressing conditions of two eradication edge halliards again, adjust the level height position of releasing pulley, then put on the support spill wheel 1.1 at releasing pulley upper opening place by changing cable;
(3) after releasing pulley position is fixing, the other end of the insulated lift rope on two carry parts is fixed on the firm object in ground by ground staff, as not having, can beat temporary ground anchor;
(4) after changing more having changed jobs of cable, unclamp insulated lift rope fixing on ground, releasing pulley is fallen to being back to ground, carry parts are dragged back shaft tower, and on tower, personnel fetch carry parts, send instrument back to ground with transmission rope, tower under personnel, the end of job.
