Technical Field

[0001] The utility model relates to the field of rail transit, in particular to an automatic train door opening and closing test device. Background Technique

[0002] An automatic train door opening and closing test device is a device specifically used to test and verify the automatic opening and closing function of the train door system. Its main purpose is to ensure that the train door can work safely and reliably under normal and abnormal conditions.

[0003] At present, the automatic door opening and closing test devices in the same industry are roughly divided into two categories. One is the microcomputer control type; the other is the PLC control type. The microcomputer control type uses computer software programming as the control core, and the PLC control type uses the PLC programmable logic controller as the core. Both can achieve the automatic opening and closing of the door, control the opening and closing time interval, and record the number of times, and have functions such as electrical interlock protection, which are safe, intelligent, and convenient. They can not only save manpower and improve efficiency, but also improve the accuracy of testing. However, as for sending the door opening and closing signal and recording the number of times, the input costs and later maintenance costs of these two types of devices are relatively high. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides an automatic train door opening and closing test device, which solves the problem that the input costs and later maintenance costs of the microcomputer control type and PLC control type devices are relatively high.

[0005] To achieve the above object, the utility model is realized through the following technical solutions: an automatic train door opening and closing test device, including a switch test mounting frame connected to the train car body. A closing detection mechanism is arranged on the front side of the switch test mounting frame. The closing detection mechanism includes an outer slide rail, a pushing slider, a door limit plate, and a micro switch. The outer slide rail is fixedly connected to the front side of the switch test mounting frame. A pushing slider is slidably connected to the outside of the outer slide rail. Two door limit plates are symmetrically arranged at the right end of the pushing slider. The pushing slider is connected to the train door through the two door limit plates and moves with the train door. The micro switch is arranged on the side far from the pushing slider and is fixedly connected to the switch test mounting frame.

[0006] Preferably, an installation and fixing mechanism connected to the train car body is arranged at the left end of the switch test mounting frame. The installation and fixing mechanism includes a connecting arm, a tightening slider, a car body limit clamping plate, a locking screw, and a fastening nut. The connecting arm is fixedly connected to the switch test mounting frame.

[0007] Preferably, tightening sliders are slidably connected to both the front and rear sides of the connecting arm. Car body limit clamping plates are fixedly connected to the outside of the two tightening sliders.

[0008] Preferably, a locking screw is penetrated between the two vehicle body limiting clamping plates, and fastening nuts are threadedly connected to both the front and rear ends of the locking screw, and the two fastening nuts are respectively arranged outside the two vehicle body limiting clamping plates.

[0009] Preferably, a plurality of anti-slip strips are arranged on the inner sides of the two vehicle body limiting clamping plates.

[0010] Preferably, a power supply is arranged at the right end of the rear side of the switch test mounting bracket, a counter is arranged on the upper surface of the power supply, and a middle relay and a time relay are respectively arranged on the left and right sides of the counter.

[0011] Beneficial effects

[0012] The utility model provides a train automatic door opening and closing test device. Compared with the prior art, the following beneficial effects are achieved:

[0013] 1. In the utility model, after the door opening and closing test device is installed on one side of the train door through the installation and fixing mechanism, the pushing slider is manually pushed, so that the two door limiting plates at the right end of the pushing slider are inserted into one side of the train door. Subsequently, when the train door is closed, the train door pushes the pushing slider to move it towards the position of the microswitch. When the pushing slider moves to the limit position, the pushing slider will press the microswitch. After the microswitch is pressed, its contacts are closed, indicating that the door body is in the closed state. This method realizes the train door opening and closing test detection by mechanical triggering. Compared with the microcomputer control type and PLC control type devices, it has lower input costs and later maintenance costs;

[0014] 2. In the utility model, through the arranged installation and fixing mechanism, before the door opening and closing test device is used, it is placed at the position of the train door, the two vehicle body limiting clamping plates are clamped on the train body on the other side of the train door, and then the fastening nuts outside the two vehicle body limiting clamping plates are respectively screwed to clamp the two vehicle body limiting clamping plates on the train body. In this way, the door opening and closing test device can be quickly and conveniently installed at the position of the train door, greatly shortening the installation time of the device and improving the work efficiency.
