Problems solved by technology

[0003] In actual use, the turning resistance of the turnout will change significantly with the state of the turnout. When the turning resistance of the turnout becomes larger than the maximum output force of the action rod, the switch machine cannot complete the switching, and the turnout is faulty and cannot be operated.
In addition, there is a possibility that the parameter change of the friction coupling and the relief valve will cause the maximum output force setting value of the action lever to decrease during work, which will also cause the switch to fail.

Embodiment 1

[0032] The invention relates to a detection method for the slippage of a friction coupling of a switch machine or the overflow of an overflow valve, such as figure 1 and figure 2 As shown, the drive locking mechanism of the switch machine is as follows figure 2 , the power output from motor shaft 1-5 is transmitted to A friction connector 1-3 through gear shaft 1-4, A friction connector 1-3 drives ball screw 1-2 to rotate, and ball screw 1-2 drives push plate Sleeve 1-7 moves, the movement process of push plate sleeve 1-7 acts with lock block 1-6, so that lock block 1-6 drives A action rod 1-1 to move, when it moves to the end position, push plate sleeve 1-7 Push the lock block 1-6 to rotate, and lock the A action lever 1-1 at the end position.

[0033] Select A action rod 1-1 as the rear end moving part, select the gear shaft 1-4 as the front end moving part, install the rear end moving part detection piece 1 on the surface of the A action rod 1-1, at a certain distance i...

Embodiment 2

[0052] like figure 1 and image 3 As shown in the figure, the transmission and locking mechanism of the switch machine is the same as that of the first embodiment, the action plates 1-8 are fixedly installed on the push plate sleeves 1-7, the action plates 1-8 are selected as the rear moving parts, and the gear shafts 1-4 are selected. For the front-end moving parts, install the rear-end moving-parts detection part 1 on the surface of the action board 1-8, and install the rear-end moving parts detection head 2 at a certain vertical distance of its motion path, and the two constitute the displacement of the action board 1-8. The sensor, the front-end moving parts detection part 3 is installed on the shaft center of the gear shaft 1-4, and the front-end moving parts detection head 4 is fixedly installed at a certain distance on its axis. The two constitute the gear shaft 1-4 angle sensor, displacement sensor and The data of the rotation angle sensor is input to the data acquisi...

Embodiment 3

[0058] like figure 1 and image 3 As shown in the figure, the transmission and locking mechanism of the switch machine is the same as that of the second embodiment. The action plates 1-8 are selected as the rear-end moving parts, and the motor shafts 1-5 are selected as the front-end moving parts. The front-end moving parts detection part 3 is fixedly installed with the front-end moving parts detection head 4 at a certain distance on its axis, and the two constitute the rotation angle sensors of the motor shafts 1-5, and the rear-end moving parts detection part 1 is installed on the surface of the action plate 1-8. The rear-end moving parts detection head 2 is fixedly installed at a certain vertical distance of its motion path, and the two constitute the action board 1-8 displacement sensors.

[0059] according to image 3 The characteristics of the structural parameters can be seen that if the speed of the motor shaft 1-5 is P (rpm), the gear reduction ratio of the motor sh...

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...
