Abstract

The utility model discloses a pulley for a cable release nozzle, which comprises a round pipe, a pulley bracket is arranged next to a nozzle of the round pipe, and a pulley is installed on the pulley bracket; the axis line of the pulley is perpendicular to the axis line of the round pipe . Beneficially, when using the cable releasing nozzle pulley of the present invention to release the cable, the outer skin of the cable is prevented from being damaged due to friction between the cable pipe nozzle and the cable.

Description

Cable release nozzle block

technical field

The utility model relates to electric power construction auxiliary equipment.

Background technique

At present, urban cables are laid in pipelines. The cable will fail after running for a period of time. Most of the reasons are that the outer sheath of the cable is damaged during laying, and moisture and rainwater enter the cable and accumulate in the weak part of the cable (middle of the cable, terminal head). Long-term operation reduces the insulation. malfunction.

At present, when the cable is released, rubber or other soft materials to prevent the cable from being scratched are placed on the pipe mouth. During the release process, it often slips or wears through and cannot play a protective role. And every place needs to be guarded by a special person, which is labor-intensive and time-consuming, which brings inconvenience to the construction and brings hidden dangers to the cable operation in the future.

Contents of the invention

In view of this, the purpose of the utility model is to provide a rapid construction equipment that prevents damage to the outer sheath of the cable.

In order to solve the above technical problems, the technical solution provided by the utility model is to provide a cable release nozzle pulley, including a round pipe, a pulley bracket is arranged next to a nozzle of the round pipe, and a pulley is installed on the pulley bracket; The axis line is perpendicular to the axis line of the circular pipe.

Preferably, the circular tube is composed of two semi-circular tubes connected by hinges and/or bolts.

Preferably, one side of the two semi-circular pipes is connected by a hinge, and the other side is connected by a bolt; the bolts are perpendicular to the round pipe.

Compared with the prior art, one of the above technical solutions has the following advantages:

1. This new type of cable release nozzle pulley uses a round tube inserted in the cable tube and a fixed pulley, so that when the cable is released, friction between the cable tube nozzle and the cable is avoided, which may cause the cable to be damaged. The outer skin is broken.

2. The round pipe of the new cable release nozzle block is composed of two semi-circular pipes connected, and the opening of the two semi-circular rings is adjusted to make it suitable for cable pipes with different pipe diameters.

Description of drawings

Fig. 1 is a perspective view of a preferred embodiment of the present invention.

Detailed ways

The following will be described in conjunction with the accompanying drawings and a specific embodiment.

See Figure 1. A cable release nozzle block described in this embodiment includes a round pipe 1, the round pipe 1 is composed of two semi-circular pipes connected by hinges and bolts, one side of the semi-circular pipes is connected by a hinge, and the other side is connected by a bolt connect. The pipe seams of the bolt and the round pipe 1 are perpendicular to each other. The opening of the round tube can be adjusted by bolts to adapt to optical cable tubes of different diameters. A pulley bracket 2 is arranged beside a semicircular tube nozzle of the round tube 1, and a pulley 3 is installed on the pulley bracket; on the side of the nozzle. When in use, insert the round pipe into the cable duct, and adjust it according to the size of the cable duct so that it is firmly stuck on the cable duct, and the traction rope enters the cable duct through the pulley. This well protects the cable from being scratched during casting.

The above are only preferred implementations of the present utility model. It should be pointed out that the above-mentioned preferred implementations should not be regarded as limitations on the present utility model, and the protection scope of the present utility model should be based on the scope defined by the claims. For those skilled in the art, without departing from the spirit and scope of the utility model, some improvements and modifications can also be made, and these improvements and modifications should also be regarded as the protection scope of the utility model.
