Description

Technical Field

[0001] The utility model relates to the technical field of maintenance of plug sliding doors of electric train sets, in particular to a DCS limit switch measuring device for plug sliding doors of electric train sets. Background Art

[0002] This year, the Sierra door has frequently malfunctioned. One serious fault is that the IDU driver's cab display screen reports fault codes 20105, 20205, 20505, 20605, 20905, and 21005, that is, the Sierra door cannot be opened and closed automatically, the closed Sierra door safety circuit is disconnected, and traction is lost. Investigation found that the fault mechanism is that the locking switch or 98% switch feedback signal is inconsistent with the Sierra door status, which is most likely caused by the DCS limit switch. Therefore, the correct setting of the DCS limit switch is very important for the closing of the EMU Sierra door. The industry requires that when the DCS switch is activated, the distance between the edge of the door bolt in front of the door leaf and the sealing frame bracket is 40-46mm.

[0003] In addition, the size of the plug door gap directly reflects the installation position of the plug door. If the gap is too large, it means that the plug door is installed too far back; if the gap is too small, it means that the plug door is installed too far forward. Both of these situations may lead to plug door flashing problems, that is, gaps appear between the door leaf and the door frame, causing hidden dangers such as light leakage, air leakage or rain leakage in the car. At the same time, this fault may also cause abnormal shaking of the plug door during the operation of the EMU, which may produce abnormal noise at the least and vibrate and crack related components at the worst, causing serious accidents of plug door separation. Therefore, it is extremely important to measure the plug door gap. The industry requires that when the plug door is fully locked, the distance from the front door bolt to the door frame bracket is 66-68mm.

[0004] During conventional measurement, the sliding door is first locked, and then two steel rulers are used to visually measure the distance from the front door bolt to the door frame support frame. This step requires the manual reading to be as accurate as possible, and any slight error may affect the measurement result. However, this traditional measurement scheme has significant defects: 1. Low maintenance efficiency; 2. High maintenance cost; 3. Large measurement error; 4. Lack of standards, purely manual detection methods are relatively backward. Summary of the invention

[0005] The purpose of the utility model is to provide a DCS limit switch measuring device for EMU plug sliding doors, so as to solve the significant defects of the traditional measurement scheme proposed in the above background technology: 1. low maintenance efficiency 2. high maintenance cost 3. large measurement error 4. lack of standards and relatively backward pure manual detection means.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A measurement device for the DCS limit switch of the plug door of a multiple unit train, comprising a main scale of the device. In the middle of the outer wall of the main scale of the device, a digital display frame is sleeved. On one side of the digital display frame, a connecting seat is fixedly connected. On one side of the connecting seat, a laser lamp fixing base is fixedly connected. On one side of the laser lamp fixing base, a laser lamp fixing seat is movably connected. A threaded hole is opened inside the laser lamp fixing base, and a bolt is threadedly connected inside the threaded hole. A laser lamp rod is clamped inside the laser lamp fixing base. By installing the main scale of the device, it can be made through numerical control milling and wire cutting processes, presenting a U-shaped structure. The main part of the main scale of the device is attached with friction strips, which enables the digital display frame sleeved in the middle of the main scale of the device to ensure that the digital display can accurately read data during the sliding process. Different from the traditional vernier caliper, the main scale of the device does not have engraved scale lines by itself, but relies on the relative displacement during the sliding process of components such as the digital display frame and the laser lamp rod on the connecting seat on one side to perform measurement and counting. Then, the bolt passes through the threaded hole to fix the laser lamp rod between the laser lamp fixing base and the laser lamp fixing seat, and attention should be paid to the orientation of the laser lamp during the assembly process to make its ray parallel to the door frame support line.

[0008] Further preferably, one end of the laser lamp rod is fixedly connected with a lamp head lens. A digital display is fixedly connected inside the digital display frame. By installing the laser lamp rod and the lamp head lens at its front end, it can emit a laser beam with a short wavelength, maintain a straight shape over a long distance, and achieve fast and accurate positioning and visual guidance. The lamp head lens can project the light beam in a straight line shape on the irradiation surface, further improving the accuracy of positioning.

[0009] Further preferably, a Bluetooth module is fixedly connected on one side of the digital display. Mounting blocks are fixedly connected on both sides of the main scale of the device. By installing the Bluetooth module, the Bluetooth module located at the upper right end of the digital display frame can be activated by the maintenance personnel after the digital display shows the reading. The built-in sensor immediately and accurately captures the reading, then converts the obtained data into a digital signal, and wirelessly transmits it to the mobile phone APP via Bluetooth, facilitating the software to quickly read and process the data. And the paperless operation reduces the burden on the operators. At the same time, the software stores the data, which is convenient for subsequent maintenance analysis as needed. The digital measurement mode can prevent incorrect replacement and missed replacement of components caused by measurement errors, and can reduce part of the economic cost.

[0010] Further preferably, the other end of the mounting block is fixedly connected with a magnetic suction base, and an installation groove is opened inside the magnetic suction base.

[0011] Further preferably, a powerful magnet is snap-fitted inside the installation groove. A magnet hole is provided inside the powerful magnet. By installing magnetic suction bases, three powerful magnets can be equipped in each of the magnetic suction bases at the left and right ends of the main ruler of the device to fix the device at the front door bolt. Powerful magnets are also installed below the magnetic suction bases to expand their contact area and achieve a fast and stable fixing effect.

[0012] Further preferably, a powerful magnet is fixedly connected to one side of the magnetic suction base. An operation button is fixedly connected inside the digital display frame body. A lever is fixedly connected to one side of the digital display frame body. By installing the operation button and the lever, the digital display in the digital display frame body can be set. Then, the lever manually slides the digital display frame body, thereby improving the practicability.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. By installing the main ruler of the device, it can be made through numerical control milling and wire cutting processes, presenting a U-shaped structure. The main body part of the main ruler of the device is attached with friction strips, which enables the digital display frame body sleeved in the middle of the main ruler of the device to ensure accurate reading of data during the sliding process. Different from the traditional vernier caliper, the main ruler of the device itself does not have scale lines engraved, but relies on the relative displacement during the sliding process of components such as the digital display frame body and the laser light rod connected to one side of it to perform measurement and counting. Then, bolts are passed through the threaded holes to fix the laser light rod between the laser light fixing base and the laser light fixing seat. During the assembly process, attention should be paid to the orientation of the laser light so that its ray is parallel to the door frame support line.

[0015] 2. By installing the laser light rod and the lamp head lens at its front end, a laser beam with a short wavelength can be emitted, maintaining a straight line shape over a long distance, achieving fast and accurate positioning and visual guidance. The lamp head lens can project the beam in a shape of a straight line on the irradiation surface, further improving the accuracy of positioning.

[0016] 3. By installing the Bluetooth module, when the digital display shows the reading, the maintenance personnel activate the Bluetooth module located at the upper right end of the digital display frame body. The built-in sensor immediately and accurately captures the reading, then converts the obtained data into a digital signal, and wirelessly transmits the data to the mobile phone APP via Bluetooth, facilitating the software to quickly read and process the data. The paperless operation reduces the burden on the operators. At the same time, the software stores the data, which is convenient for subsequent maintenance analysis as needed. The digital measurement mode prevents incorrect or missed replacement of components caused by measurement errors and can reduce some economic costs. BRIEF DESCRIPTION OF THE DRAWINGS
