[0032] In the description of the utility model, it needs to explain, unless otherwise expressly provided and limited, the term "installation", "connection", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected, it can be mechanical connection, or electrical connection, it can be directly connected, or indirectly connected through intermediate medium.

[0033] In the operation process of the motor train unit, the closed state and quality of the door system greatly affect the safety and punctuality rate of the motor train unit daily operation, therefore, when the motor train unit is daily maintained, the door closing condition needs to be accurately adjusted, especially when the door is closed, the gap between the door carrying frame striker and the lock switch needs to be detected and corrected.

[0034] As shown in Figs. 1-6 The utility model provides a motor train unit plug door striker position measurement adjusting device, including adjusting module 1 of adjusting the striker position and measurement module 2 of measuring the striker position to confirm whether the striker installation position is normal, wherein adjusting module 1 includes the position adjusting base body 10 for being connected with the striker and being fixed and being pressed with the switch, and the position adjusting base body 10 is provided with the fixed groove 103 for being connected with the striker, and measurement module 2 includes the measurement base body 20 for being pressed with the striker and determining whether the striker installation position is normal.

[0035] The motor train unit plug door striker is located in the plug door system and is specifically installed at the edge of the door frame or door leaf. When the motor train unit plug door is closed, the plug door striker cooperates with the door lock mechanism to ensure that the plug door system can be normally locked and keep good sealing performance. Therefore, the accuracy of the position of the plug door striker is related to whether the plug door can work normally and the safety of the working operation.

[0036] The motor train unit plug door striker position measurement adjusting device in the application can efficiently and accurately complete the adjustment and measurement of the striker position and effectively improve the efficiency and safety of the motor train plug door operation, and reduce the failure rate caused by the inaccuracy of the striker position.

[0037] As shown in the accompanying drawings, the adjusting base 10 comprises a first clamping block 101 and a second clamping block 102, and a fixing groove 103 for clamping the fixed block is arranged between the first clamping block 101 and the second clamping block 102. Figs. 1-4

[0038] In detail, the groove width of the fixing groove 103 is 12.5 mm, and the groove width of the fixing groove 103 is equal to the thickness value of the block. The upper wall surface of the block is in mutual abutment with the bottom wall of the first clamping block 101 in the fixing groove 103, and the lower wall surface of the block is in mutual abutment with the top wall of the second clamping block 102 in the fixing groove 103.

[0039] Further, the first clamping block 101 and the second clamping block 102 are both plate-shaped structures with a preset thickness, the length of the first clamping block 101 is greater than that of the second clamping block 102, and the width of the first clamping block 101 is smaller than that of the second clamping block 102.

[0040] It needs to be further explained that the first clamping block 101 and the second clamping block 102 are both plates with a preset thickness. The side surface of the first clamping block 101 and the second clamping block 102 is arc-shaped. Specifically, since the block is a ring structure with an arc, in order to better engage the block with the adjusting base 10, the side surface of the adjusting base 10 engaged with the block has a preset curved arc.

[0041] Further, the first clamping block 101 and the second clamping block 102 are provided with curved end faces, and the curved end faces are in the same plane as the slot opening of the fixing groove 103, so that when the adjusting base 10 is aligned and installed with the block, the block is engaged and embedded in the fixing groove 103.

[0042] Obviously, the cross-sectional shape of the adjusting base 10 is an irregular concave shape. The length of the first clamping block 101 is greater than that of the second clamping block 102, and the width of the first clamping block 101 is smaller than that of the second clamping block 102. The specific length of the first clamping block 101 and the second clamping block 102 is determined by the clamping depth of the block and the shape of the corresponding position of the block, and personnel in the field can select and design according to the actual situation. Preferably, the length of the first clamping block 101 is 25 mm, and the length of the second clamping block 102 is 15 mm.

[0043] The first clamping block 101 is provided with a mounting hole 1011, and a fixing member is arranged in the mounting hole 1011 to connect and fix the adjusting module and the block in one body.

[0044] ​Further, the mounting hole 1011 can be any one of a circle, an ellipse, a square, a rectangle, a polygon, and the like, and other shapes can be selected and designed by those skilled in the art according to actual needs, as long as the mounting hole 1011 can cooperate with the fixing member to achieve the mounting function. Further, the mounting hole 1011 on the first clamping plate corresponds in position to the assembly hole on the striker, so that the relative position of the adjustment module 1 and the striker can be determined, and the fixing member is further used to consolidate the adjustment module 1 and the striker.

[0045] Preferably, the mounting hole 1011 in the embodiment is a circle with a radius of 2.5 mm.

[0046] The adjustment module 1 further comprises a fixing member installed in the mounting hole 1011, which can connect and fix the adjustment module 2 and the striker as a whole.

[0047] Further, the fixing member can be any one of a bolt, a screw, a screw, and a pin. Preferably, a bolt is used as the fixing member in the embodiment to fasten the adjustment module 1 to the striker, so that the position of the striker can be adjusted by moving the adjustment module 1.

[0048] As shown in FIG. 1, Figs. 5-6 The application further comprises a measurement module 2 for measuring the position of the striker to confirm whether the installation position of the striker is normal. The measurement module 2 comprises a measurement base 20 in contact with the striker.

[0049] Further, the measurement base 20 is a double-curved plate structure, and the double-curved plate structure is a fan ring body with a predetermined thickness.

[0050] The double-curved structure of the measurement base 20 is adapted to the structure of the striker to be measured, so that the measurement base 20 can be better attached to the striker during measurement of the position of the striker, thereby ensuring the accuracy of the measurement result. One end of the measurement base 20 is provided with a bent portion 201, and the other end is provided with an inclined clamping portion 202, and the bent portion 201 and the inclined clamping portion 202 are located on the same side of the measurement base 20. The design of the bent portion 201 and the inclined clamping portion 202 is beneficial to the stability of the measurement module 2 during use, so as to ensure that the measurement module 2 does not move during measurement.

[0051] Further, the bent portion 201 is perpendicular to one end of the measurement base 20, and the inclined clamping portion 202 is raised at a predetermined angle from the other end of the measurement base 20.

[0052] Specifically, the bent portion 201 is formed by being vertically raised from one end of the measurement base 20, so that the measurement module 2 can adapt to irregularly shaped objects or enter narrow spaces for measurement. The inclined clamping portion 202 is used to fix or clamp the object, and also determines the position of the object relative to the measurement base 20.

[0053] The preset angle range for the tilted bracket 202 is 40-50°. Preferably, based on the shape of the impact block to be measured, the preset angle for the tilted bracket 202 is 45°, allowing the measuring module 2 to more accurately determine whether the impact block is installed correctly.

[0054] Furthermore, the inclined card portion 202 is provided with a card slot 2021 for fixing, and the opening of the card slot 2021 faces the side where the long curved edge of the measuring base 20 is located.

[0055] The slot 2021 on the inclined clamp 202 can be used to fix or hold the impact block to be measured, so that the measuring module 2 can perform measurement operations more stably. The opening direction of the slot 2021 further enhances the accuracy and consistency of the measurement. According to the opening direction of the slot 2021, the operator can more easily see the relative position between the impact block and the measuring module 2 during use, improving the convenience of use.

[0056] Preferably, the adjustment module 1 and the measurement module 2 in this application are both integrally molded structures. Because there are no seams or connection points in the integrated structural design, the adjustment module and the measurement module are more robust and can withstand greater stress and deformation.

[0057] In the process of using this application, first loosen the bolts on the door carrier, install the adjustment module 1 onto the bolt, manually push and adjust the door carrier to simulate a closed state, so that the adjustment module 1 contacts the S1 switch roller. At this point, the position of the bolt is determined, and tighten the bolt fixing bolts (fixed parts). Use a marker to mark the contact surface between the bolt and the S1 switch, and then manually operate to simulate a closed state to trigger the S1 switch to release. Afterwards, manually open the door, and according to the position of the marker on the bolt, place the measuring module 2 of the bolt position above the bolt to determine whether the bolt installation position is normal.

[0058] Specifically, the adjustment base 10 of the adjustment module 1 is installed with the impact block. The relative position of the adjustment module 1 and the impact block is determined by the corresponding position of the mounting hole 1011 on the first clamping plate and the assembly hole on the impact block, so that the impact block is engaged and embedded in the fixing groove 103. The door frame is manually pushed and adjusted to simulate the closed state, so that the S1 switch roller and the adjustment base 10 of the adjustment module 1 approach each other until the adjustment base 10 presses and triggers the S1 switch. Marks are made at the contact surface between the impact block and the S1 switch to determine the initial position of the impact block. The fixing bolts of the impact block are then tightened to ensure that the position of the impact block is fixed.

[0059] The installation position of the striker is determined by the adjusting module 1, and the initial position of the striker is identified and recorded, the manual operation simulates the closed door state, the striker triggers the S1 switch, and it is ensured that the contact between the striker and the S1 switch is normal, the door is manually opened, the striker is separated from the S switch, and the measurement is prepared, the measuring module 2 is installed above the striker, the measurement base 21 is a double-curved edge plate structure, can be connected with the striker, the striker position is determined by the bending part and the inclined clamping part of the measurement base 21, and the striker position is determined by the bending part and the inclined clamping part of the measurement base 21. If the bending part is completely attached to the striker, and the clamping groove of the inclined clamping part is fixed or clamped with the striker, it indicates that the striker position is normal, otherwise, the striker position needs to be further adjusted. Through the cooperative operation of the adjusting module and the measuring module, the adjustment and measurement of the striker position can be quickly and accurately completed, the gap between the striker and the S1 switch can meet the standard, the failure rate of the door is reduced, and the operation efficiency of the EMU train is improved. The adjusting module and the measuring module are standard size universal parts, and the size data of the relative position of the striker is not required in the adjustment and measurement process, and reading is not required, and when the striker position meets the standard requirements of the application, the striker position is considered to be normal.

[0060] It should be noted that the striker position adjusting device provided in the application is a split structure, the initial position of the striker is determined by the adjusting module, and then the measuring module is used to measure whether the striker position is normal. In actual application, the two modules can be used separately as required, for example, only the adjusting module is used when the striker position needs to be determined, and only the measuring module is used when the installed striker needs to be judged whether the installation position is normal, and no requirements and limitations are made.

[0061] Compared with the prior art, the striker position adjusting device has the following beneficial technical effects:

[0062] The striker position adjusting device quickly adjusts and determines the installation position of the striker, improves the installation and positioning efficiency, and the measuring module can determine whether the installation position of the striker is in place after manually simulating the closing of the EMU door, greatly improves the time of traditional striker adjustment and striker measurement, reduces the failure rate of the door, and improves the operation efficiency of the EMU train.

[0063] The overall structure of the EMU plug door striker position measurement and adjustment module is simple, the manufacturing cost is low, and the maintenance and repair cost of the EMU device operation is reduced.
