Cable protection pipe sealing test device

Abstract

The invention relates to a cable protection pipe sealing test device comprising a frame, a first sealing installation tower base and a transmission assembly. The transmission assembly is provided witha second sealing installation tower base; and the bottom end of a tested cable protection pipe is fixedly connected to the first sealing installation tower base. The transmission assembly is providedwith a servo motor. The first sealing installation tower base and the second sealing installation tower base include pedestals and inflation sealing rings. The test device has the following advantages: the inflatable sealing ring is inflated through an air pump and deformation is caused under the effect of the internal pressure of the inflatable sealing ring, so that that the inflatable sealing ring expands outwards to be in close contact with the cable protection pipe and thus the sealing effect of the cable protection pipe is realized; water is injected into the cable protection pipe through a water inlet pipe and a water pressure is set through a pressure gauge, only whether any water leakage occurs at a joint needs to be observed after testing, and the sealing performance of the cableprotection pipe is determined by observing whether the value of the pressure gauge decreases or not.

Description

technical field [0001] The invention relates to a sealing test device for a cable protection tube. Background technique [0002] The cable protection tube refers to a metal protection tube with a certain mechanical strength that is laid on the outer layer of the cable to prevent the cable from being damaged. Communication cables and steel wire ropes are charged to protect cables, switches, core boards, so that the whole machine will not be burned out, and also play a certain role in isolating the magnetic field interference of power lines. The protection quality of the tube, while the seal detection of the existing cable protection tube is manually sealed at both ends through the sealing plug, and the positioning effect of the sealing plug at both ends of the cable protection tube is poor, the operation process is heavy, time-consuming and laborious. It is easy to affect the sealing quality, and the detection effect is low. Contents of the invention [0003] The purpose ...
