Description

Technical Field

[0001] The utility model belongs to the field of water spraying and raining test devices for rail passenger cars, and in particular relates to a train body leakage test device with a wiping and cleaning function. Background Art

[0002] After the rail passenger car body manufacturing process is completed, it must undergo a test acceptance of the body spraying and leak detection link to check the sealing and waterproof performance of the roof and side structures such as the roof panel, fan and pantograph installation opening, side wall panels and windows. Figure 1 and Figure 2 As shown, the existing rain leakage detection equipment is a door arch spray pipe P similar to a train limit frame installed in the spray test workshop, which uses the nozzle P1 array on the door arch spray pipe P to spray the intersection area M of the arc plate and the side wall of the train to be inspected and the side wall window area N with high-pressure water mist. At the same time, the external structure of the car body is cleaned and washed.

[0003] Then, with the continuous improvement of new trains, the old arch-shaped spray pipe P without limit size adjustment function and position movement function has gradually been unable to adapt to the design changes of train structure. For example, in a certain type of low-floor urban rail train project, the car body and side windows are vertically distributed bonding structures. When using the old arch-shaped spray pipe P to spray and leak the car body of this type of train, the high-pressure water flow is difficult to contact the side top of the car body, and the spray leak detection pressure and dirt cleaning effect are not ideal; at the same time, this type of vehicle has a large number of electrical equipment on the roof and a complex structure, resulting in a large-area penetration of the leak position after the spray leak detection in the car, and it is difficult to quickly and accurately find the specific leak point. The existing solution is to use a traction vehicle to drag the car body along the spray workshop rails for many times, so that the test vehicle moves a distance of about 0.5 meters each time, and the spray angle of the nozzle P1 on the arch-shaped spray pipe P is changed accordingly, and then the spray leak detection is repeatedly re-performed, so as to realize the investigation of key leak areas and the key high-pressure spray decontamination of local cleaning areas. Utility Model Content

The scissor-type hydraulic lifting platform E is positioned by the self-locking mechanism of the universal wheels provided by the scissor-type hydraulic lifting platform E, so that the distance between two adjacent sets of rain test devices is 8 meters. Next, slide the vertical plate slider 7-2 along the rectangular lateral groove 5-1-1 and drive the sliding vertical plates 7-1 of the two single-side bracket mechanisms B1 to narrow the distance. When the lateral cleaning mechanism D2 fixed on the sliding vertical plate 7-1 is about 30cm away from the side wall or window of the vehicle body, screw the positioning bolt 5-4 into the positioning bolt hole 5-3-1 located adjacent to the rear of the vertical plate slider 7-2 on the end surface of the slide groove base plate 5-3, so as to limit the sliding vertical plate mechanism 7. Then, use the manual hydraulic mechanism of the scissor-type hydraulic lifting platform E to adjust the overall height of the vehicle body outer contour bracket mechanism B until the spiral atomizing nozzle 10-1 on the inclined section 10B of the spray pipe is about 30cm away from the roof arc plate, lock the height of the scissor-type hydraulic lifting platform E and the train body leakage test device with wiping cleaning function, and then connect the water inlet of the three-way pipe 8 to the high-pressure water hose to start the vehicle body spray leakage detection test.

[0058] If no leakage is found in the initial spray leakage detection test of the vehicle body being inspected, the vertical plate slider 7-2 is slid along the rectangular lateral through groove 5-1-1 and drives the two single-sided bracket mechanisms B1 to further narrow the distance between the sliding vertical plates 7-1. When the lateral cleaning mechanism D2 fixedly connected to the sliding vertical plate 7-1 is in contact with the side wall or window of the vehicle body, the positioning bolt 5-4 is screwed into the positioning bolt hole 5-3-1 on the end face of the slide groove base plate 5-3 and adjacent to the rear of the vertical plate slider 7-2, thereby limiting the sliding vertical plate mechanism 7. After that, the bidirectional screw drive motor 1-2 drives the width adjustment mechanism A to synchronously and reversely contract its two U-shaped nut mechanisms 1-4, and again slowly and synchronously lowers its own height through the two scissors-type lifting platforms E and drives the core structure G of the rain test device to lower its height until the oblique cleaning mechanism D1 fixedly connected to the corner seat plate 3-1 contacts the edge of the roof arc plate and the top of the side wall at the same time, and the bidirectional screw drive motor 1-2 is applied with fine macro adjustment through the stepper motor program control and the two U-shaped nut mechanisms 1-4 are further slowly contracted and moved closer to each other. At this time, the oblique cleaning mechanism D1 will push the piston spring seat 3-4 under the reaction force of the roof arc plate and apply pressure to the compression spring 3-3. When one-third of the corner base guide tube 3-6 is inserted into the corner seat plate 3-1, the bidirectional screw drive motor 1-2 is stopped. At this point, all the cleaning mechanisms D can be started, and the roof, side walls and windows of the vehicle body can be wiped by rotating the flexible turntables 14 on the oblique cleaning mechanism D1 and the lateral cleaning mechanism D2 to efficiently remove stains on the vehicle body.

[0059] If leakage occurs on the vehicle body during the initial spraying and rain leakage detection test, the water stains on the vehicle body are first wiped off with the cleaning mechanism D in the same manner as described above to accelerate the drying speed of the vehicle body. Then, a separate set of leakage test devices corresponding to the area near the leakage point is started, and the spray flow and pressure level are reduced accordingly according to the program parameters required by the checklist. The vehicle body leakage test device of the utility model is moved a short distance along the workshop floor rail as a whole by the scissor-type hydraulic lifting platform E. In this way, a small-scale rapid inspection of specific leakage points on the roof can be achieved by relying solely on the device of the utility model without the need to tow the vehicle repeatedly. This improves production efficiency and shortens the test cycle.
