Abstract

The utility model relates to a cable traction device for a buried ground wire pipe of a household distribution box, which comprises a traction seat, a pulley support rod, a support pipe, a fixed pulley and a positioning rod; the supporting tube is welded and fixed with the upper end and the lower end of the traction seat, and the supporting tube extends outwards from the end face of the traction seat by a corresponding length so as to meet the restricted conditions of different heights and different operation areas; both ends welding pulley bracing piece bearing fixed pulley about the traction seat, the pulley bracing piece is gone up alternately and is equipped with the locating lever, and the locating lever fixes a position fixed pulley with the bracing piece simultaneously, prevents to receive to energetically make the pulley off tracking cause the accidental injury when dragging the cable. The utility model discloses can make the operation personnel carry out the business turn over household electrical conduit cable laying that the villa block terminal buried underground and laid conveniently laborsavingly in narrow space, can practice thrift spare part cost again, the protection cable avoids out damage and trouble, and the operation is got up very easily, quick, and then can reach labour saving and time saving's purpose.

Description

Cable traction device for buried ground wire pipe of household distribution box

Technical Field

The utility model relates to an electric cable installation lays technical field, specific cable draw gear for buried line pipe of block terminal of registering one's residence that says so.

Background

The threading pipe that villa district used at present, when carrying out the method of intraductal laying electric cable, pass the threading pipe with the haulage rope earlier, the haulage rope other end is peeled off first department with the cable and is beaten the joint, then waterproof the binding is carried out to the joint, pulls the haulage rope, takes out new cable, accomplishes the change. Many problems can appear in the whole process, because the house lead-in box is installed in the villa building in the narrow place position in space such as building way mouth or basement storeroom, generally lay by outdoor to indoor direction when laying cable, in the house lead-in box threading process, need two at least workers to need upwards to draw and drag the haulage rope with methods such as hand vice or steel pipe winding haulage rope, again because of the villa molding is complicated, house lead-in threading pipe elbow is many, the electronic box mounting height (more than 1.5 meters), and bury the intraductal easy moist rust of spool, the cable draws the process very difficult, draw and accomplish back haulage rope and all scrap and can not reuse drawing once drawing, even meet the house lead-in spool and draw to drag for too long time and hinder, the cable is blocked and can't withdraw from, cause the condition such as cable and the spool is scrapped.

Disclosure of Invention

The utility model aims at overcoming prior art's defect, provide a block terminal of registering one's residence buries cable draw gear for ground wire pipe, can make the operation personnel carry out intraductal cabling conveniently laborsavingly, can practice thrift spare part cost again, and the protection cable avoids out of order, and is the increase of enterprises.

In order to solve the technical problem, the utility model discloses a realize like this:

the utility model provides a cable draw gear for house-entry block terminal buried ground wire pipe which characterized in that: the device comprises a traction seat, a pulley support rod, a support tube, a fixed pulley and a positioning rod; the supporting tube is welded and fixed with the upper end and the lower end of the traction seat, and the supporting tube extends outwards from the end face of the traction seat by a corresponding length so as to meet the restricted conditions of different heights and different operation areas; the pulley bracing piece bearing fixed pulley is welded at both ends about the traction seat, the pulley bracing piece is gone up to cross and is equipped with the locating lever, and the locating lever fixes a position the fixed pulley with the bracing piece simultaneously, prevents to receive to energetically make the pulley off tracking cause the accidental injury when dragging the cable.

The utility model has the advantages that: the cable is protected from being damaged by being pulled by large force while the sufficient pulling effect is ensured to be achieved when the pulling force is applied to the cable; due to the design of the pulleys, the stress direction is changed, the operation is more convenient, and the conditions that the stress of operators and cables in the threading pipe is uneven and the like are reduced; the design of traction seat plays installation and handy effect, has protected the cable again when having protected the haulage rope, improves work efficiency, saves operating time, can practice thrift spare part cost again, and the protection cable avoids the trouble, and the operation is got up very easily, fast, and then can reach labour saving and time saving's purpose.

Drawings

The invention will be described in further detail with reference to the following drawings and embodiments:

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic view of an installation operation;

shown in the figure:

Detailed Description

As shown in fig. 1 and 2: a cable traction device for a buried ground wire pipe of a household distribution box comprises a traction seat 1 and support pipes 3 fixed at two ends of the traction seat 1, wherein the support pipes 3 are welded with the upper end and the lower end of the traction seat 1, and the support pipes 3 extend outwards from the end surface of the traction seat 1 by corresponding lengths; both ends welded fastening about traction seat 1, fixed pulley bracing piece 2 bearing fixed pulley 4 and fix a position the fixed pulley by locating lever 5 and bracing piece 3.

Fixed pulley bracing piece bearing fixed pulley is welded at both ends about the traction seat to fix a position the fixed pulley simultaneously by locating lever and bracing piece, prevent to receive to energetically make the purpose that the pulley off tracking caused the accidental injury when dragging the cable.

The traction seat comprises a traction seat and supporting pipes fixed at two ends of the traction seat, wherein the supporting pipes are welded and fixed with the upper end and the lower end of the traction seat.

The traction seat is portable, suitable, convenient to disassemble and assemble and capable of walking along with use. The fixed pulley is convenient and labor-saving, reduces the number of operators, and does not damage cables caused by uneven handling.

The cable laying method in the threading pipe aiming at the traction device in the embodiment comprises the following steps:

a. a constructor 8 makes the traction power assisting device lean against the wall surface 9, so that the supporting tube 3 and the wall surface 9 form an included angle of 30-45 degrees, and the other end of the supporting tube is supported on the ground 10;

b. a common traction rope 6 (steel wire or threading device) for threading is adopted, is penetrated through an outdoor buried pipe and is pulled out from the end 7 of an electrical box for house entrance;

c. a common traction rope (steel wire or threading device) for threading is upward from the lower end of the traction seat and downward in the opposite direction after winding the pulley;

d. pulling the steel wire until the cable slides out of the threading pipe;

e. and (4) removing the cable head, and drawing the steel wire out of the device.

Of course, the above description is not limited to the above examples, and technical features of the present invention that are not described in the present application may be implemented by or using the prior art, and are not described herein again; the above embodiments and drawings are only used for illustrating the technical solutions of the present invention and are not intended to limit the present invention, and the present invention has been described in detail with reference to the preferred embodiments, and those skilled in the art should understand that changes, modifications, additions or substitutions made by those skilled in the art within the spirit of the present invention should also belong to the protection scope of the claims of the present invention.
