Abstract

The invention belongs to the monitoring and measuring method of turnout switching equipment in the field of rail transit, and is a monitoring device and method for whether the maximum output force of a turnout switch machine (hereinafter referred to as a switch machine) matches the current load. The detection method of friction coupling slipping or overflow valve overflow of the rat machine, which monitors the linear moving parts and rotating moving parts through a non-contact method, and according to the influence of the friction coupling slipping or overflow valve overflow on the back-end moving parts, to Judging whether the maximum output force of the switch machine is too small compared with the current load, guide the maintenance personnel to adjust and maintain the switch machine in time, and prevent the occurrence of jamming faults in the switch conversion. The non-contact monitoring method has no effect on the conversion of the switch machine and will not The reliability of the switch machine is reduced due to the failure of the switch machine due to the installation of the sensor.

Description

technical field

[0001] The invention belongs to a monitoring and measurement method of switch conversion equipment in the field of rail transit, and is a device and method for monitoring whether the maximum output force of a switch machine (hereinafter referred to as a switch machine) matches the current load. The detection method of the slippage of the friction coupling of the rut machine or the overflow of the relief valve. Background technique

[0002] The switch machine is used to switch and lock the switch, and express the position and state of the switch. The output force of the action rod pushes or pulls the switch point rail (heart rail), so that the movable part of the switch can be converted. , All types of switch machines are equipped with a mechanism for limiting the maximum output force of the action rod. Usually, the electric switch machine uses a friction coupling (torque limiter) as the mechanism to adjust and limit the maximum output force. The electro-hydr...
