Description

New control cable pay-off frame

technical field

The invention relates to the field of electric power, in particular to a novel control cable pay-off frame.

Background technique

Cables play a vital role in substations, and each substation requires a large number of cables. Cable laying is required in new substation infrastructure, substation expansion, and technical renovation and overhaul projects. However, laying a large number of cables is a complex and heavy work, and it is extremely difficult to complete it by manpower alone, so it needs to be completed with the help of some devices. The cable pay-off frame is the most commonly used device in cable laying.

The cable pay-off frame is the most common device in construction projects such as electric power and telecommunications, and plays an important role in projects that require cable release, such as new substation infrastructure and technical renovation and overhaul. The traditional cable pay-off stand is mainly composed of two triangular-shaped supports and a solid drill rod. When releasing the cable, the positive cable is placed on the two triangular supports through the drill rod, and the cable reel is manually lifted off the ground by the hydraulic mechanism on the two supports for release. . The old-style cable pay-off stand has obvious disadvantages such as heavy and difficult to carry, time-consuming to install, difficult to rotate the wire, requires full-time manpower, and low efficiency. Moreover, the hydraulic mechanism is prone to oil leakage. After a long time, insufficient hydraulic pressure will cause the device to fail, and maintenance is also difficult. Very inconvenient.

detailed description

The present invention is further described in conjunction with the following examples.

The new control cable pay-off frame is used to control the release of the cable coil 5 on the cable reel 3 as shown in Figure 4, including the fixed chassis 1 shown in Figure 1 and the fixed chassis 1 as shown 2 shows the rotating disk 2. The center of the fixed chassis 1 is welded with a drill rod 4 for nesting the cable reel 3 . The center of the rotating disk 2 is provided with a cylindrical hollow rod 6 for passing through the drill pipe 4; the bottom of the rotating disk 2 is equipped with a plurality of rotating wheels 7 as shown in Figure 3, each The two rotating wheels 7 are fixed by screws.

As a preference, in this embodiment, the fixed chassis 1 is made of steel plate with a diameter of 55-65 cm, which can bear enough weight to ensure that the entire pay-off stand device will not shake when the cable 5 is unwound. dump. The height of the drill rod 4 is 45-55 cm. Further, the diameter of the fixed chassis is 60cm; the height of the drill rod 4 is 53cm.

The rotating disc 2 can rotate freely and can drive the cable reel 3 to rotate, which is the most critical part for realizing the cable pay-off. In this embodiment, the rotating disk 2 is made of steel plate with a diameter of 55-65 cm. Further, the rotating disk 2 is made of steel plate with a diameter of 60 cm, and five rotating wheels 7 are provided. The screw rod used to fix the rotating wheel 7 can be freely disassembled and installed, which is convenient for replacement after the bearing is damaged, thereby achieving durability.

Preferably, the weight of the fixed chassis 1 and the rotating disk 2 is 49kg, and the load-bearing capacity of the entire device is 3t.

The new control cable pay-off frame provided by the present invention is suitable for various types of cables, including 500mZR-KVVP22-4*4 cables, 1000mZR-KVVP22-10*2.5 cables, 1000mZR-KVVP22-7*2.5 cables, 800mZR- KVVP22-14*4 cables, low-voltage power cables and optical cables, etc., and meet the use standards of electric field tools.

When in use, place the fixed chassis 1 on a flat ground, then put the rotating disk 2 on the fixed chassis 1, the rotating disk 2 can rotate freely, and the cable reel 3 is placed on the rotating disk 2 through the drill pipe 4 On, pulling the cable 5, the rotating disk 2 rotates to drive the cable reel 3 to rotate, thereby realizing the purpose of releasing the wire.
