Abstract
The utility model discloses a large-section bender for a pull wire. The large-section bender is characterized in that hinge seats (2) are arranged at the front ends of two handles (1), the hinge seats on the two handles are alternately used, and a pulley groove (3) is hinged between the hinge seats on the two handles via a hinge shaft (4); and during the use of the large-section bender, bending for the pull wire can be finished only by expanding the two handles, penetrating the pull wire through the pulley groove, and then closing the handles. Compared with the prior art, the large-section bender disclosed by the utility model has the following advantages: 1, by adopting the bender for the pull wire disclosed by the utility model for performing a replacement operation for the pull wire, 8.5 minutes of time is reduced during production for a pull wire clamp, and about 70 minutes of time can be reduced for a rod tower with 8 pull wires on the foundation, thus greatly increasing the working efficiency; 2, by adopting the bender for the pull wire, bending for the pull wire can be finished only by one person, thus reducing labour intensity and improving economic benefits; and 3, by adopting the bender for the pull wire, the resilience force of a steel strand is controlled, thus avoiding personal injury on operating personnel and improving the safety.
Description
Technical field
The utility model relates to a kind of bracing wire bending apparatus, especially a kind of heavy in section (more than GJ-100) bracing wire bending apparatus.
Background technology
As everyone knows, transmission line of electricity is owing to being exposed to all the year round open-air operation, be subject to for a long time the impact of atmosphere pollution and artificial destruction, the phenomenon such as often occur that the pole wire corrosion is serious, disconnected strand of bracing wire and pull-back wire line are cut off, in order to guarantee the safe and stable operation of circuit, the every need every year changed bracing wires in a large number, this shows, workload is very big.
Need the bent steel twisted wire owing to changing bracing wire, in order to UT wire clamp or wedge type clamp to be installed, and heavy in section bracing wire (more than GJ-100) bending is very difficult, and the people that strength is less is at all curved motionless, needs two people compounding practices simultaneously.There is great screen resilience during due to the steel strand wires bending, do not hold and easily spring back to even lower crosspiece part of hand, face, cause personal injury accident, and the continuous bend bracing wire, operating personnel easily pull muscle of back.
Therefore, designing a kind of safety, heavy in section, labour-saving (more than GJ-100) bracing wire bending apparatus, is the present technical issues that need to address.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of safety, heavy in section, labour-saving (more than GJ-100) bracing wire bending apparatus.
The technical scheme in the invention for solving the technical problem is:
Heavy in section bracing wire bending apparatus, front end at two handles is equipped with free bearing, free bearing on two handles is staggered to be used, be hinged with sheave by hinge between the free bearing on two handles, only need during use two handles are opened, pulley groove is passed in bracing wire, and then close handles, namely complete the bending of bracing wire.
Preferably, be set with the locating slide sleeve card on handle, be hinged with the bracing wire fixture block on the locating slide sleeve card.
Preferably, the cross section of described handle is semicircular ring, and diameter is 33mm, wall thickness 5mm.Namely
HandThe handle wall thickness is 5mm, and diameter is that the 33mm seamless steel pipe is made.
Compared with prior art, the utlity model has following advantage:
1. take the utility model bracing wire bending apparatus to change the bracing wire operation, made a guy clamp time shorten 8.5 minutes, a base has the shaft tower of 8 bracing wires, just nearly 70 minutes of the shortening time of energy, has greatly improved operating efficiency;
2. take this bracing wire bending apparatus, only need a people just can complete the bending of bracing wire, alleviated labour intensity, improved economic benefit;
3. take this bracing wire bending apparatus, controlled the screen resilience of steel strand wires, avoided the operating personnel to be subject to personal injury, improved security.
Description of drawings
Fig. 1 is structural representation of the present utility model (closing up);
Fig. 2 is structural representation of the present utility model (opening).
The specific embodiment
As shown in the figure, heavy in section bracing wire bending apparatus, front end at two handles 1 is equipped with free bearing 2, free bearing on two handles is staggered to be used, be hinged with sheave 3 by hinge 4 between the free bearing on two handles, only need during use two handles are opened, pulley groove is passed in bracing wire, then close handles, namely complete the bending of bracing wire.
Be set with locating slide sleeve card 5 on handle 1, be hinged with bracing wire fixture block 6 on locating slide sleeve card 5.
The cross section of described handle 1 is semicircular ring, and diameter is 33mm, wall thickness 5mm.
Claims (3)
1. heavy in section bracing wire bending apparatus, it is characterized in that: the front end at two handles (1) is equipped with free bearing (2), free bearing on two handles is staggered to be used, be hinged with sheave (3) by hinge (4) between the free bearing on two handles, only need during use two handles are opened, pulley groove is passed in bracing wire, and then close handles, namely complete the bending of bracing wire.
2. bracing wire bending apparatus in heavy in section according to claim 1, is characterized in that: be set with locating slide sleeve card (5) on handle (1), be hinged with bracing wire fixture block (6) on locating slide sleeve card (5).
