ZD6 type point switch notch image acquisition device

Abstract

The invention provides a ZD6 type point switch notch image acquisition device which comprises a base, an insulation protective cover, a cover plate, a transparent panel and a camera module. The base is installed on a point switch contact seat, and the base and the insulation protective cover are connected through a hinge and are fixed and positioned through a positioning pin. The camera module isinstalled on the top of the insulating protective cover and provided with an LED light supplementing lamp for vertically shooting a notch image. The transparent panel is used for blocking a camera module lens hole in the insulating protective cover, and after the camera module is installed in the shell on the upper portion of the insulating protective cover, pouring sealant is used for pouring, and a cover plate is used for blocking the camera module. And the requirement of the protection grade IP54 is met. The ZD6 type point switch notch image acquisition device is simple and reliable in installation structure and convenient to maintain, normal use of a point switch is not affected, and monitoring can be accurately and reliably carried out.

Description

technical field [0001] The invention relates to the field of switch machine gap detection, in particular to a ZD6 type switch machine gap image acquisition device. Background technique [0002] The quality of the turnout switching equipment will directly affect the safety of the train. In order to ensure the safety of the train and the operational efficiency of the line, and reduce the maintenance and repair times of the turnout equipment, it is particularly important to monitor the gap of the switch machine in real time. [0003] The switch machine gap monitoring system is the basic data to realize the maintenance of switch switching equipment, and it is also an important tool for signal maintenance and management. In the prior art, the notch image acquisition device of the ZD6 switch machine uses a metal bracket to install the camera above the contact seat. This design has the following disadvantages: [0004] (1) It is necessary to remove the insulating protective cove...

AI Technical Summary

Problems solved by technology

[0004] (1) It is necessary to remove the insulation protection cover that comes with the switch machine, and there is a risk of electric shock

[0005] (2) Since the camera is installed directly above the gap observation window, which blocks the view of the manual observation of the gap, when the maintenance personnel observe the gap manually, the camera needs to be disassembled, and the gap monitoring system needs to be re-calibrated after disassembly, resulting in Inconvenient to use and maintain

[0006] (3) The installation of the camera bracket needs to re-disassemble part of the internal structure of the switch machine, which is risky, and the internal space of the switch machine is small and inconvenient to operate

[0007] (4) The brackets used for the camera are all made of metal, and the switch machine is in a vibrating environment. Since the protective cover for insulation is removed, when the bracket fails or the installation is loose, the camera bracket may cause a short circuit of the switch machine contacts, which poses a huge safety hazard. Hidden danger

[0008] (5) The notch image acquisition device does not meet the protection level of IP54
