Description

a wire rack

technical field

The invention relates to the field of tools for electric power engineering, in particular to a pay-off rack.

Background technique

During the construction of the substation project, many problems were found in the laying out of cables. If you use the traditional method of unwinding, you need to lay the cable reel flat on the ground and let it out around the reel. The released cable will be twisted. If the sheath is damaged, the cable is prone to dead bends, which seriously affects the service life of the cable. The twisted cables are laid on the cable support, which is difficult to straighten out and smooth, and will also cause unsightly construction techniques. When the pay-off length is long, the error of cable length caused by pay-off twisting will increase, which will cause a waste of resources, and special personnel must be set up at each corner of the cable trench to take care of it, which wastes manpower. Since payout is an important part of electrical construction engineering, how to solve these problems in cable payout, save manpower and material resources in the payout link, and ensure the service life of the cable and the construction quality of the project are urgently to be solved. Practical problems.

Contents of the invention

In order to make up for the above deficiencies, the present invention provides a pay-off stand with simple structure and convenient operation, which will not cause the cable to be twisted or bent during use. The pay-off stand of the present invention greatly improves the service life of the cable, and Improve the construction quality and construction efficiency of cable engineering.

Technical scheme of the present invention is:

A pay-off rack, comprising a bottom plate 9, on which a slideway 7 is arranged obliquely, on the bottom plate 9, two wheel grooves 4 are arranged in parallel; on the wheel groove 4, a first sheave 3 is arranged, so that The top surfaces of the two side walls of the wheel groove 4 are paired with grooves 5 for installing the second sheave 6, and at least two pairs of grooves 5 are provided on the wheel groove 4. The second sheave 6 and the second sheave 6 A sheave 3 is arranged in parallel; the sheave support 2 is arranged obliquely on the base plate 9 or the wheel groove 4, and a baffle plate for blocking the cable reel is installed on the sheave support 2 to prevent the cable reel from falling off the bottom plate 9 The third sheave 1 is arranged parallel to the first sheave 3 .

When using the pay-off rack of the present invention, the pay-off rack is placed horizontally on the ground, the diameter of the circular baffles on both sides of the cable reel 10 is used to select the appropriate groove 5, and the second sheave 6 is placed on the corresponding In groove 5. After the second sheave 6 is placed, the construction personnel will push the cable reel 10 onto the pay-off frame through the slideway 7, so that the circular baffle on the left side of the cable reel 10 is placed on the first sheave of the left wheel groove 4 3 and the second sheave 6, and the circular baffle on the right side of the cable reel 10 is placed on the first sheave 3 and the second sheave 6 of the right side wheel groove 4, in addition, the cable reel 10 The baffle is in contact with the third sheave 1 on the sheave bracket 2. After the cable reel 10 is pushed into place, hold the end of the cable 11 and pull the cable 11, the cable reel 10 will rotate on the sheave, so as to realize the wire release, and the cable will not be twisted during the wire release process. Strength, bending, etc. After the wiring is completed, the remaining cables 11 are fixed, and the cable tray 10 is pushed down the bottom plate 9 to get final product.

Preferably, the first sheaves 3 on the two wheel grooves 4 are arranged coaxially; the grooves 5 on the two wheel grooves 4 are arranged coaxially. It can ensure that the stress points at the bottom of the baffle on both sides of the cable tray 10 are symmetrical.

Preferably, two sheave brackets 2 are provided, and a third sheave 1 is provided on each sheave bracket 2 . It can ensure that the upper stress points of the baffles on both sides of the cable tray 10 are symmetrical.

Preferably, the first sheave 3 , the second sheave 6 and the third sheave 1 are completely the same sheave. The width of each sheave groove portion is equal to the thickness of the cable drum 10 to increase the stability of the present invention.

Further, the first sheave 3 is not detachably arranged on the wheel groove 4 .

As a preferred solution, the third sheave 1 is not detachably arranged on the sheave bracket 2 .

As a preferred solution, the front end of the base plate 9 is hingedly provided with a handle 8 . It is convenient to move or carry the pay-off frame of the present invention.

As a preferred solution, rollers with locking devices are arranged under the bottom plate 9 . Easy to move pay-off rack.

The beneficial effects of the present invention are:

1. On the top surface of the two side walls of the wheel groove, there are grooves for installing the second sheave in pairs. At least two pairs of grooves 5 are set on the wheel groove 4. This setting is for adjusting the second sheave 6 and the first sheave. The spacing between the sheaves 3 is suitable for cable drums of different diameters.

2. When paying off, you only need to pull the cable to drive the cable reel to rotate on the pay-off frame. The friction is small and easy to use, which greatly saves manpower.

3. Using the pay-off frame of the present invention to pay off the cables can avoid twisting force on the cables due to torque, thereby avoiding damage to the cables and making the laid cables more beautiful.

4. Easy control to stop pay-off, reduce the error of pay-off length and save resources.

5. Simple structure, low cost, simple operation and flexible use.
