Abstract
The utility model discloses a pulley-type wire tensioner, relating to the technical field of power line tensioning equipment. The pulley-type wire tensioner comprises a fixed pulley block and a fixed pulley yoke, wherein the fixed pulley block includes at least two fixed pulleys arranged in the up-down direction, and the fixed pulley yoke is provided with a second lower hook. The pulley-type wire tensioner further comprises a movable pulley block and a movable pulley yoke, wherein the movable pulley block includes at least two movable pulleys arranged in the up-down direction, and the movable pulley yoke is provided with a first upper hook and a first lower hook. The fixed pulley block and the movable pulley block are connected by ropes. The pulley-type wire tensioner provided by the utility model is simple in structure, convenient in operation, simple to produce and capable of providing uniform tension, as well as efficiently adjusting the sagging of the wires so as to meet the requirements of the standard.
Description
Technical field
The utility model relates to power circuit stringing device technique field.
Background technology
In the overhead transmission line Construction of Tension Stringing, the too tight or too loose normal operation that all can influence power circuit of circuit.Traditional line tightening method is: the manpower backguy, and the sag of range estimation lead is wasted time and energy like this, and the dynamics of stringing is difficult to consistent, and the lead sag degree of tight mistake is loose differing also, and the normal operation of circuit also is affected.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, easy to use, labour-saving pulley-type wire grip, can make things convenient for rapid adjustment lead sag degree, makes it to reach the required standards.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of pulley-type wire grip, comprise a fixed pulley group and fixed pulley frame, described fixed pulley group has 2 fixed pulleys that are arranged above and below at least, and described fixed pulley frame is provided with second lower draw-bar; Also comprise a running block and movable pulley frame, described running block has 2 movable pulleys that are arranged above and below at least, and described movable pulley frame is provided with hook, first lower draw-bar on first; Link to each other with rope between described fixed pulley group and the running block.
Be preferably, described fixed pulley is two, and described movable pulley is two.
Be preferably, described fixed pulley frame, movable pulley frame include 2 pressing plates, and described fixed pulley or movable pulley all fix by axle and pressing plate.
Be preferably, described rope begins coiling from first lower draw-bar of described movable pulley, and the free end of rope lays out from described movable pulley end.
Be preferably, described fixed pulley frame is provided with hook on second.
The beneficial effect that adopts technique scheme to produce is: the utility model is simple in structure, and is easy to operate, make easily, and tension uniform, the sag degree of can the labour-saving adjusting lead reach the required standards, and has general practicality.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model;
Mark among the figure: 1-movable pulley; The 2-movable pulley; 3-second lower draw-bar; The 4-pressing plate; Hook on the 5-second; 6-first lower draw-bar; The 7-axle; The 8-rope; Hook on the 9-first.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1, the pulley-type wire grip comprises a fixed pulley group and fixed pulley frame, and described fixed pulley group has 2 fixed pulleys that are arranged above and below 2 at least, and described fixed pulley frame is provided with second lower draw-bar 3; Also comprise a running block and movable pulley frame, described running block has 2 movable pulleys that are arranged above and below 1 at least, and described movable pulley frame is provided with and links up with 9, first lower draw-bar 6 on first; Link to each other with rope 8 between described fixed pulley group and the running block.
Be preferably, described fixed pulley 2 is two, and described movable pulley 1 is two, also can select three or more pulley assembling according to actual conditions.
Be preferably, described fixed pulley frame, movable pulley frame include 2 pressing plates 4, and described fixed pulley 2 or movable pulley 1 all fix by axle 7 and pressing plate 4, also can select suitable pressing plate according to actual conditions, and fixed form also can adopt bolt to connect easy disassembly.
Be preferably, first lower draw-bar 6 of described rope 8 follow-up pulleies 1 begins coiling, and free end follow-up pulley 1 end of rope 8 lays out; Described fixed pulley frame is provided with links up with 5 on second, rope 8 also can begin coiling from second hook 5 of fixed pulley 2, and free end lays out from fixed pulley 2 ends.
The utility model is simple in structure, easy to operate, make easily, tension uniform, the sag degree of adjustment lead that can be time saving and energy saving reaches suitable standard, specifically form assembly pulley by two fixed pulleys 2 and two movable pulleys 1, utilize the laborsaving and fixed pulley 2 of movable pulley 1 can change the principle of the direction of pulling force, at an end that needs stringing wire grip is installed, with movable pulley 1 first on drag hook 9 connect an end of wire grips, second time drag hook 3 of fixed pulley 2 colludes on the distaff of terminal pole, and the free end of pulling rope 8 during stringing is because the winding of rope 8 has determined the labour-saving how much, rope 8 follow-up pulleies 1 begin coiling, free end follow-up pulley 1 end lays out, and the rope 8 that links to each other with movable pulley 1 has 5 sections and bears pulling force like this, just can be than the power of economizing 5 times without assembly pulley.
