Description

pull line tool

technical field

The invention relates to a tool for installation and construction of high and low voltage lines, in particular to a tool for pulling wires suitable for binding various electric poles.

Background technique

During the construction of the transmission line, the poles in the high and low voltage power supply lines are used to erect the transmission wires. In the fixed installation procedure of the poles, after the poles are erected to the ground, the poles need to be auxiliary fixed with pull wires. When installing the guy wire, one end of the guy wire is first bent and folded in half by the UT clamp to form a double-strand guy wire, and then the overlapping part of the double-strand guy wire is bound with iron wire. This process is called "tying the guy wire". The prior art of backguy is to alternately use multiple portable tools such as vise, wrench, sledgehammer, and galvanized iron wire is wound and bound on double backguy. During the winding process, the "Code for Construction and Acceptance of 35kV and Below Overhead Power Lines for Electrical Installation Engineering" (GB50173-92) requires the iron wire to be tight and uniform without gaps, no hard bends, neat and beautiful, and cannot damage the wire. Galvanized layer. The existing method of pulling the wire is time-consuming and laborious. When the force is not enough, the iron wire is easy to slip, and the winding quality is poor. In addition, the distance between the curved double-ply stay wire gradually decreases from top to bottom, so when winding the double-ply stay wire, it is not easy to determine when the winding can be stopped, and it is easy to cause waste of iron wire.

Contents of the invention

The technical problem to be solved by the present invention is to provide a wire pulling tool that saves time and labor, has high work efficiency, has a low probability of damage to the galvanized layer of the iron wire, and can determine the winding degree of the iron wire.

In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:

The pulling wire tool includes a strip-shaped insulating board, handles are fixedly arranged at both ends of the insulating board, a hanging wire rod for hanging iron wires is provided at one end of the side of the insulating board, and the other end or the middle part of the insulating board is also There are wire slots of different widths, and a support frame for supporting iron wires is provided on the front of the insulation board between the wire slot and the hanging wire rod. The support frame includes a support rod perpendicular to the front of the insulation board to support The upper end of the rod is provided with a guide groove for guiding the iron wire, and the front of the insulating plate is also hinged with a telescopic ruler for measuring the distance between the double-strand wires wrapped around the iron wire and the winding length of the double-strand wires, and the telescopic ruler is hinged outside the wire groove through a pin The front end of the insulation board; the back side of the insulation board is fixedly provided with a metal rod whose diameter along the length direction of the insulation board is larger than that of the iron wire.

The improvement of the present invention is that: the wire passing slot is divided into a first wire passing slot and a second wire passing slot, the width of the first wire passing slot is smaller than that of the second wire passing slot, and the first wire passing slot is located in the second wire passing slot. inside of the trunking.

A further improvement of the present invention is that: the edges of the first wire passing groove, the second wire passing groove, and the guide groove of the support frame are smooth and arc-shaped.

The further improvement of the present invention is that: the hanging wire rod on the side of the insulating plate is replaced by a winding wheel, and the winding wheel is hinged on the side of the insulating plate through a pin; the guide groove on the support frame is replaced by a pulley, and the pulley is horizontally Installed on top of the support frame.

Owing to having adopted above-mentioned technical scheme, the technical progress that the present invention obtains is:

The pulling wire tool of the present invention can evenly and tightly wind the iron wire on the pulling wire, has high working efficiency, saves time and effort, does not damage the galvanized layer of the iron wire, and is a pulling wire tool that can determine the winding degree of the iron wire. The present invention is provided with hanging wire rod, before pulling wire, at first iron wire is coiled around hanging wire rod on the hanging wire rod to form an iron abacus wound on the hanging wire rod, there is certain gap between hanging wire rod and iron wire, and iron wire Friction resistance, there must be enough force to pull the wire, so that the wire is always in a tight state during the winding process, making the winding more firm and tight.

Both ends of the insulation board of the present invention are fixedly provided with handles. When in use, the staff act on the two handles with both hands at the same time, place the insulation board horizontally on the double-strand stay wire, and rotate and wind around the double-strand stay wire clockwise or counterclockwise. save time and energy. In addition, there are slots of different widths on the insulating plate, which are suitable for winding iron wires of various specifications.

The back of the insulating board of the present invention is fixedly provided with a metal rod with a diameter greater than that of the iron wire. When using the present invention, the metal rod is in direct contact with the double-strand stay wire, which avoids the contact between the entire insulating board surface and the double-strand stay wire, and reduces the iron wire. During the winding process, the friction between the insulating plate and the double-strand wire saves time and effort.

The end of the front of the insulation board of the present invention is hinged with a telescopic ruler. When the insulation board begins to wrap around the double-strand guy wire, the telescopic ruler is placed along the length direction of the insulation board, and the telescopic ruler can measure the double-strand guy wire wound by the iron wire at any time. The distance between the curved double-strand wires gradually decreases from top to bottom. Use the telescopic ruler to observe the change in the distance between the double-strand wires wrapped around the iron wire to determine the degree of tightness of the wire winding and prevent the occurrence of iron wire winding tightness. The phenomenon of inconsistency ensures that the wire winding is neat and beautiful. When it is found that the distance between the double-ply guy wires wrapped with iron wires no longer changes, rotate the telescopic ruler so that the direction of the telescopic ruler is parallel to the double-ply guy wires, and measure the winding length of the double-ply guy wires wrapped by iron wire at any time, according to industry regulations Determine the wire winding length of the double-ply guy wire, and there will be no waste of wire due to over-winding due to uncertain wire winding degree.

The front of the insulation board of the present invention is provided with a support frame with a guide groove, and the iron wire passes through the guide groove and is input into the wire passing groove. Due to the existence of the support frame, there is a smooth transition process when the iron wire is input into the wire passing groove , there will be no dead bend and hard bend of the iron wire, and the damage of the galvanized layer of the iron wire will be avoided. In addition, the iron wire is always between the wire grooves, which ensures the stability of the wire passing through the wire grooves, so that the winding of the iron wire is stable and compact.

The edges of the wire passing groove and the wire groove of the support frame of the present invention are smooth and arc-shaped, so when the iron wire is input, the galvanized layer of the iron wire will not be damaged, and the service life of the iron wire is prolonged.
