Easy-to-maintain talcum powder laying device prior to cable coiling

Abstract

The invention discloses an easy-to-maintain talcum powder laying device prior to cable coiling. The talcum powder laying device comprises a coiling frame, a fulcrum shaft rod, a rotating rod, a bracket and a sleeve clamping mechanism, and has the beneficial effects that the sleeve clamping mechanism different from a conventional structure can lay the talcum powder on the cable. A mode of inorganically filling a sheath tube of a high-voltage power cable with talcum powders breaks a traditional mode of an organic polymer plastic auxiliary reinforcing material. The cable can be threaded into thesleeve by coiling. By special airbag-shaped upper and low clamping blocks in a laying frame in the sleeve clamping mechanism, sufficient clamping force can be maintained in the process of laying talcum powder in the sleeve clamping mechanism, the sleeve can be prevented from rupturing due to excessively hard member during operation, and the equipment can be easily maintained.

Description

technical field [0001] The invention relates to the field of cable equipment, in particular to a talc powder laying device before cable winding which is convenient for maintenance. Background technique [0002] At present, in order to protect the urban and rural living and investment environment in the construction of the national grid and reduce the spider-like overhead power lines, the power cable transmission line has been buried from the overhead, and the pipe laying is widely used in the power industry due to its excellent characteristics. Sheath tubes for high-voltage power cables can effectively protect the inner core of cables and have been used on a large scale in the power grid transformation of the power industry. However, as plastic sleeves, the sheath tube is very sensitive to temperature changes.

Problems solved by technology

[0002] At present, in order to protect the urban and rural living and investment environment in the construction of the national grid and reduce the spider-like overhead power lines, the power cable transmission line has been buried from the overhead, and the pipe laying is widely used in the power industry due to its excellent characteristics. Sheath tubes for high-voltage power cables can effectively protect the inner core of cables and have been used on a large scale in the power grid transformation of the power industry. However, as plastic sleeves, the sheath tube is very sensitive to temperature changes. It is different from steel, Concrete and other pipe materials are very different, and their performance will be significantly reduced under the influence of the environment or external force for a long time, resulting in deformation and damage of the casing, and gradually losing its use function. When the cable core continues to carry current, it will generate high temperature and then affect the service life of the casing. In order to alleviate the above-mentioned effects and ensure that the pipeline does not undergo strength damage within the specified service period, the filling modification method of the unique particle structure of talc powder is usually used instead of the traditional calcium carbonate as a filler to produce sheath tubes for high-voltage power cables to make up for this. Disadvantages. Due to the characteristics of talc powder that is easy to rise, ordinary talc powder laying devices are likely to cause powder blockage and stop the device. If the metal components are too hard, the clamping force applied will be too large and the casing will break. Based on the above premise, this case A maintenance-friendly pre-cable talcum powder laying device was developed to solve this problem
