Special mold for plugging fireproof mud in cable holes

Abstract

The invention provides a special mold for plugging fireproof mud in cable holes, and relates to the field of electrical equipment. The special mold comprises a left half ring and a right half ring, wherein the left half ring and the right half ring are connected together; a rotating ring is arranged on a cylinder body surrounded by the left half ring and the right half ring; a plurality of telescopic fixing mechanisms are annularly arranged on the rotating ring; and a heating plugging mechanism is mounted on the cylinder body. According to the special mold, the fireproof mud plugging process is changed from manually repeated splicing into mechanical auxiliary plugging forming, the process is fast and convenient, the thickness of the fireproof mud is consistent, the technological level is improved, the plugging quality of holes is guaranteed, the problems that the fireproof mud is difficult to extend at low temperature and the manual splicing process is unsightly are thoroughly solved,and the past operation process is changed. The short circuit accidents caused by fire and small animals are completely eradicated.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a special mold for plugging cable holes with fireproof mud. Background technique [0002] Fireproof mud is mainly used to block the cable holes inside the switchgear or line ring network cabinet in the station. First, it can play a role in flame retardancy and prevent losses caused by fire; second, it can prevent short-circuit accidents caused by the entry of small animals. However, there are the following disadvantages and inconveniences in the daily construction process: 1. The temperature in winter is low, and the ductility of the fireproof mud is greatly affected. Manual sealing is time-consuming and laborious, and the construction is difficult. 2. After the hole is penetrated into the cable, it is difficult to manually ensure the thickness of the fireproof mud is consistent during the sealing process. The aesthetics of the mud process is greatly reduced, and th...
