Tool and method for processing gap between speed sensor cable and pouring sealant

Abstract

The invention discloses a tool and method for processing a gap between a speed sensor cable and a pouring sealant, and the tool comprises a tool body 1, the center of the tool body 1 is provided with a conical hole 2, and the upper part of the conical hole 2 extends to form a cable through hole 3; a rectangular groove 4 used for clamping the upper end of a sensor 6 is formed in the bottom face of the tool body 1. The method comprises the steps that silicone grease is smeared on the inner walls of the conical hole and the cable via hole in the tool body, then colloid is added into the tool, the two parts of the tool are buckled and pressed at the positions of the speed sensor and the sensor cable, the upper end of the speed sensor is clamped in the rectangular groove in the bottom face of the tool body, and the sensor cable penetrates through the cable via hole of the tool body. After the tool is pressed, the tool is lifted upwards, and the tool and the colloid are separated. The method is reasonable in design and has good practical application value.

Description

technical field [0001] The invention relates to the technical field of gap repair at the junction of two objects, in particular to a repair method for a gap between a cable and a potting glue, in particular to a tool and method for repairing a gap between a speed sensing cable and a potting glue. Background technique [0002] The speed sensor is a key component of the traction motor of rail transit trains, which is used to detect the rotation speed of the traction motor for train traction control. The speed sensor of a traction motor of a certain type of train needs to be installed inside the motor due to the limitation of installation space. When the environment and voltage difference are large, there will be a gap between the individual speed sensor cable and the potting compound after about 6 years of operation. Due to the existence of gaps, moisture and condensed water will enter the sensor, resulting in speed sensor failure. The speed sensor failure can cause abnormal ...

AI Technical Summary

Problems solved by technology

[0005] Disadvantages of the existing technology: Since the colloid is manually applied and formed by the self-adhesiveness of the colloid, the gap cannot be effectively sealed; after the colloid is solidified and soaked in water for a long time, the insulation test fails, and the sealing effect is not achieved; at the same time, it is difficult to form the glue
