Abstract

The invention relates to a built-in anchoring balance weight detection device for a rail transit overhead line system. The built-in anchoring balance weight detection device is mainly composed of automatic monitoring equipment, a mounting mechanism and a solar power generation device. The automatic monitoring device is installed on the inner wall of the built-in anchoring hollow steel stand column through the mounting mechanism, and the solar power generation device is installed outside the steel stand column and supplies power to the automatic monitoring device. The automatic monitoring device is used for monitoring the position of the balance weight and the health state of a steel cable for hanging the balance weight; and by sensing external environment temperature and humidity value data, the recovery state of the steel cable is calculated through an algorithm. The problems that in the current maintenance technical scheme, the states of the built-in anchoring balance weight and the suspension steel cable of the built-in anchoring balance weight mainly depend on manual ladder climbing for visual inspection, the efficiency is low, and the accuracy is not high are solved.

Description

technical field [0001] The invention relates to the field of intelligent monitoring of equipment status in a rail transit power supply system, in particular to a built-in anchor drop detection device for a rail transit catenary. Background technique [0002] During the actual construction and installation of catenary built-in anchorage, due to various subjective and objective factors, the actual a and b values ​​of the compensator (a and b values ​​of the weight) are often inconsistent with the design values, such as Figure 8 As shown in (a), the a and b values ​​of the compensator refer to respectively: the distance from the end of the steel cable 403 connecting the weight 402 to the guide wheel 404 is the value a, and the distance from the lower edge of the weight to the ground is the value b. Simultaneously because steel cable 403 forms 58 ° of included angles with pendant, the wearing and tearing of steel cable 403 at guide wheel 404 position is bigger, and the phenomeno...
