Description

Technical Field

[0001] The utility model belongs to the technical field of cable laying, and particularly relates to a port protection structure for cable pipeline laying. Background Technique

[0002] With the accelerating process of modernization, the requirements for municipal engineering are also getting higher and higher. It not only needs to meet safety requirements but also be as aesthetic as possible. This has led to the gradual replacement of overhead distribution lines by underground cables. When laying underground cables, the cables need to be laid in underground manholes. However, during the power construction process, for the cables laid in manholes, the situation of working in a limited space is often faced.

[0003] When laying cables with a larger wire diameter in the manhole and the bending radius of the cable is relatively large, the surface insulating skin of the cable will rub against the cable pipe when entering the cable pipe, resulting in damage to the surface of the cable. In some construction sites, a sleeve protection form is used to protect the pipe port, but there is a lack of a locking structure between the sleeve and the pipe, resulting in the situation that the sleeve often slips out of the pipe port during actual construction. Therefore, a port protection structure for cable pipeline laying is needed, which can effectively protect the pipe port through the protection structure, and the protection structure can be firmly connected to the pipe, so as to ensure the stability of the protection structure during use. Summary of the Utility Model

[0009] Preferably, split bolts are installed on the surfaces of the sleeve, the first hole plate, and the second hole plate.

[0010] The beneficial effects of the present utility model are as follows:

[0011] 1. By inserting the sleeve into the inner cavity of the cable pipe, then rotating the second hole plate to drive the rotating rod to drive the rectangular block to move, the telescopic rod contracts and drives the top plate to tightly press the cable pipe.
