Abstract

The invention discloses an electric transmission line erection tightener which comprises a fixed frame body, a traction support and a clamp. The traction support is provided with 1-3 traction wheel sets. Each wheel set is composed of rotating wheels and compression wheels, wherein the rotating wheels and the compression wheels are matched with one another, the rotating wheels are in transmission connection with one another, and the compression wheels are connected with a pressure pull rod connected with the traction support in a penetrating mode. A compression spring and a lever type pull rod operation mechanism are arranged on the pressure pull rod. The rotating wheels are connected with a hand-cranking mechanism through chain transmission pieces. Single-direction locking mechanisms used for preventing the rotating wheels from rotating reversely are arranged on the chain transmission pieces. The tightener is exquisite is operation, can be operated by one person, does not need ground coordination, can be stopped at any time for rest in the wire tightening process, is improved in construction efficiency by more than ten times when calculated in a man-hour mode, greatly reduces labor intensity, and especially and reliably ensures person safety of rod treading persons.

Description

A kind of transmission line sets up wire grip
Technical field
The invention belongs to superhigh pressure technical field of construction, be specifically related to a kind of transmission line and set up wire grip.
Background technology
In ultra-high-tension power transmission line erection process, must, by the transmission pressure tension between two tower bars, then be connected to corresponding insulator string bottom.Traditional line tightening method be utilize tied rope or tension disk wire is fastening, with stay cord, cross cross-arm, upper and lower personnel coordinate, and transmission pressure is strained.The method wastes time and energy, and sets up efficiency low, and cooperation personnel are many, and labour intensity is large, workmen's distance especially, and contact difficulty, once coordinate badly, brings great threat to the safety of stepping on tower personnel, even leads to serious accident.Thus, bring great stress usually to power transmission engineering workmen.In CN 202840374 U, disclose a kind of wire grip, comprised fixing-line device, middle wirerope, ratchet and hook steel wire rope; The left end clamping transmission pressure of described fixing-line device, the right-hand member of fixing-line device connects the left end of middle wirerope; The right-hand member of middle wirerope is fixedly connected with the swiveling wheel of ratchet, and ratchet right-hand member is connected with hook steel wire rope left end.The right-hand member of described middle wirerope passes the through hole on the swiveling wheel that is located at ratchet and is fixedly connected with swiveling wheel.The right-hand member of described hook steel wire rope is provided with U-shaped hook.The present invention can guarantee operator's personal safety, and stringing is connected firmly, and handled easily is saved raw material, raises labour efficiency; Yet its operation is comparatively complicated, between ratchet and steel wire rope hook place, still have a segment distance, make it when shaking ratchet, the distance needing, has increased operating personnel's work load, therefore needs a kind of simple in structure, easy and simple to handle and can be by the wire grip of transmission line tension.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, easy and simple to handle and can be by the wire grip of transmission line tension.
Realizing the technical scheme that object of the present invention adopts is: a kind of transmission line sets up wire grip, comprise fixing bracket body, towing bracket and anchor ear, described towing bracket arranges 1 ~ 3 pair of traction wheels, described traction wheels consist of the moving runner cooperatively interacting and contact roller, between described moving runner, chain is in transmission connection, described contact roller is connected with described towing bracket and installs the pressure pull bar being connected, Compress Spring and lever pull bar operating mechanism are set on described pressure pull bar, described moving runner is connected with hand-operated mechanism by chain driving member, described chain driving member is provided for preventing the single direction locking mechanism of moving runner reversing.
Described towing bracket is flexibly connected with fixing bracket body, and removable adjustment.
Described moving runner and contact roller arrange grooving, described grooving arranges wear-resisting antiskid layer, described contact roller one side arranges wire guide frame, described chain driving member arranges chain tensioning mechanism, described chain driving member is flexibly connected with fixing bracket body and towing bracket respectively, and described pressure pull bar top arranges spring pressure adjusting mechanism.
Described fixing bracket body and towing bracket all adopt articles made of aluminium alloy.
The present invention is when carrying out transmission line erection construction, this wire grip dismounting can be put in kit, stepping on tower personnel brings on tower, by anchor ear, fixing bracket body is fixed on tower bar cross-arm, again towing bracket is connected on fixing bracket body, and then described chain driving member is arranged on respectively on fixing bracket body and towing bracket, complete the installation of wire grip.When carrying out stringing operation, as long as moving runner and contact roller are separated by pull bar operating mechanism, wire is tapped to described wire guide frame inner side, wire falls in the grooving of contact roller automatically, releasing lever operating mechanism, under the effect of Compress Spring, contact roller and moving runner nature are by conductor clamping.Now, rotate hand-operated mechanism and can carry out stringing work.Due to the effect of single direction locking mechanism, even if stop shaking of hand-operated mechanism, wire can slippage yet.After operation completion, as long as reverse operating can take off euphroe dismounting, also can be designed to quick fixation structure by connecting elements is installed, more quick box lunch.Because this euphroe has simple in structurely, lightweight, cost is low, the advantage such as easy to carry, so can be equipped with two tower bar wire erection requirements in work progress, switch use, after second tower rod guidance line is fastening, then row is removed the wire grip on first tower bar.This wire grip operation is very light and handy, and a people just can operate, and without ground, coordinates, the rest of can stopping work at any time in stringing process, calculates during by people, and its efficiency of construction can improve more than 10 times, labour intensity alleviates greatly, especially makes the personal safety of pedaling bar personnel obtain reliable assurance.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is the structural representation of the present invention's one side;
Fig. 2 is the structural representation of opposite side of the present invention.
Embodiment
As depicted in figs. 1 and 2: a kind of transmission line sets up wire grip, comprise fixing bracket body 1, towing bracket 11 and anchor ear 3, described towing bracket 11 arranges 1 ~ 3 pair of traction wheels, described traction wheels consist of the moving runner 6 cooperatively interacting and contact roller 5, between described moving runner 6, chain is in transmission connection, described contact roller 5 is connected with described towing bracket 11 and installs the pressure pull bar 8 being connected, Compress Spring 7 and lever pull bar operating mechanism are set on described pressure pull bar 8, described moving runner 10 is connected with hand-operated mechanism 2 by chain driving member 4, described chain driving member 4 is provided for preventing the single direction locking mechanism of moving runner reversing.
