Background technology
At present, along with the fast development of national economy, the development of power industry stringing field of engineering technology is more and more faster, and electric stringing project progress is had higher requirement, and particularly also has higher requirement to relating to stringing operation in stringing engineering.When the construction of line, traditional stringing mode mainly contains following several.With tractor or tractor-type strand mill, when wire is tightened to a certain degree, made a sign on wire by personnel on bar.After wire is transferred to ground, wire clamp is installed, then is pressed wire to carry out hanging wire by ground staff after tightly getting up with tractor or strand mill simultaneously, often the multiplex power inequality of people easily causes the accident, and this mode is used big machinery, is subject to landform restriction.
The stringing instrument using is now as wire grip, adopt manpower stringing mode, in use often because taking over, wire grip while drawing, is subject to the human body arm system of extending a time limit, stringing engineering can not once be completed, need reuse wire grip twice, not only waste time and energy, and operation is very complicated, speed is slower, thereby affects operating efficiency; In addition, poor stability when stringing, people is many cannot be protected evenly firmly, and people can not tightly get up line less, causes construction quality poor, and security reliability is poor.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of electric stringing manpower wire tensioning device, easy to operate, and good stability, effectively ensures construction quality, replaces the stringing mode of traditional tractor or strand grinding machine, uses manpower and material resources sparingly.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of electric stringing manpower wire tensioning device, comprises wire grip, 1 two-wheel movable pulley, 2 fixed pulleys, 2 wire grips and steel wire rope; Described wire grip is fixed on the middle and lower part of shaft tower; Described 2 fixed pulleys are separately fixed at the two ends of strain cross arm; Described steel wire rope comprises steel wire rope I and steel wire rope II; Lower sheave and its two ends that described steel wire rope I is walked around two-wheel movable pulley are connected with wire grip; Described steel wire rope II is walked around the top sheave of two-wheel movable pulley, and its left and right sides is walked around respectively and is fixed on the fixed pulley at strain cross arm two ends and connecting respectively 1 wire grip.
Particularly, described wire grip is hand-rail type wire grip; Described wire grip is fixed on shaft tower and apart from ground 1.5-3 rice; Described wire grip is fixed on shaft tower by U-shaped anchor ear.
Described fixed pulley is fixed on strain cross arm by fastening bolt.
The beneficial effect that adopts technique scheme to produce is: stringing operation when the utility model is used for the construction of line, adopt pulley gear can ensure the balance of wire steadily and between two wires, good stability, effectively ensures that the radian between wire is consistent, contributes to improve construction quality; Wire grip and fixed pulley all adopt the fixture of versatility, easy for installation flexible, simple to operate; The utility model replaces the stringing mode of traditional tractor or strand grinding machine, is not subject to the restriction of construction of line site contour, uses manpower and material resources sparingly, and operating efficiency is high.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Electric stringing manpower wire tensioning device as depicted in figs. 1 and 2, comprises 1,2 fixed pulleys of 7,1 two-wheel movable pulley of wire grip 2,2 wire grips 8 and steel wire ropes; Described 2 fixed pulleys 2 are fixed on respectively the two ends of strain cross arm 3 with fastening bolt; Described steel wire rope comprises steel wire rope I 5 and steel wire rope II 4; Lower sheave and its two ends that described steel wire rope I 5 is walked around two-wheel movable pulley 1 are connected with wire grip 7; Described steel wire rope II 4 is walked around the top sheave of two-wheel movable pulley 1, and its left and right sides is walked around respectively and is fixed on the fixed pulley 2 at strain cross arm 3 two ends and connecting respectively 1 wire grip 8.
Described wire grip 7 is hand-rail type wire grip, is fixed on shaft tower 6, apart from 2 meters, ground by U-shaped anchor ear 10; The round steel that U-shaped anchor ear adopts processes, and at the semicircle place of U-shaped anchor ear iron hammer draw down, on head, puts screw thread and matching nut.
This novel device is mainly used for the stringing operation of 10KV and 0.4KV circuit, a tight middle wire after the wire of first tight both sides on 10KV circuit, two wires on first tight both sides in the time that 0.4KV circuit four coil holders are established, two wires in rear tight centre.
When use, first two fixed pulleys are fixed on strain cross arm, wire grip is fixed on shaft tower, lay steel wire rope I and steel wire rope II.Carry out two wires when simultaneously fastening, first two wire grips connected respectively and fix two wires, shake wire grip, tense wire rope I, drives steel wire rope II by two-wheel movable pulley, and strains two wire grips; Continue shake wire grip, by steel wire rope I, two-wheel movable pulley is moved down, and then steel wire rope II drives two wire grips and two wires to move to the strain cross arm of head of mast simultaneously, complete the operation of stringing stringing.Carry out a wire when fastening, one of them wire grip is fixed on strain cross arm or shaft tower, another wire grip connects and fixes a wire, then carries out stringing operation.
Stringing operation when the utility model is used for the construction of line, adopts pulley gear can ensure wire steadily and two wire balances, good stability when stringing, effectively ensure that the radian between wire is consistent, wire grip and fixed pulley all adopt the fixture of versatility, easy for installation flexible, simple to operate.
