AI Technical Summary

Technical Problem

The sliding contact line is prone to freezing in low-temperature environments, which can cause condensation between the current collector and the sliding contact line, affecting normal use and posing safety hazards. In addition, the contact between the brush and the sliding contact line is unstable, which may lead to spark discharge and equipment damage.

Method used

A constant temperature heating device for sliding contact lines was designed, including a heating element, a power connection component, and a starting element. The heating element is controlled by a temperature sensor to maintain a constant temperature when the current collector is stopped, preventing condensation on the current collector and the sliding contact line and ice formation on the spring, thus ensuring contact between the brush and the sliding contact line.

Benefits of technology

It effectively prevents condensation between the current collector and the sliding contact line, avoids spring icing, ensures stable contact between the brush and the sliding contact line, and improves the safety and stability of equipment use.

Abstract

This utility model relates to a constant temperature heating device for a sliding contact line, including a sliding contact line, a current collector, and a constant temperature heating mechanism. In the actual process of powering a lifting elevator via the sliding contact line, when it is necessary to provide constant temperature protection for the current collector in the stopped state, the heating element can be installed on the sliding contact line at the position where the current collector is stopped. When the lifting elevator moves the current collector to the stopped position, the current collector triggers the starting element, which in turn drives the heating element to run. The heating element then provides constant temperature heating to the current collector. When the current collector leaves, the starting element is triggered again, stopping the heating element. This allows the sliding contact line and current collector to be used conveniently in low-temperature environments, preventing the current collector and the sliding contact line from condensing together when the elevator is stopped, and preventing the spring inside the current collector from freezing, thus ensuring contact between the brush and the sliding contact line.
