Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary measuring devices for plug sliding doors of electric train sets, in particular to a measuring device for side doors of CRH3 electric train sets. Background Art

[0002] The plug door system is one of the important factors affecting the safe operation of EMUs on the running lines. The plug door switching action of high-speed EMUs is mainly composed of important components such as main and auxiliary locks, door leaves, drives, and drive guide rods. The plug door is a precision component of the EMU, and the size adjustment requirements of the components of its plug door structure are relatively high. Regarding the failure of the 98% limit switch of the side door during the operation of CRH380B / 3C EMUs and the size measurement and adjustment process of the 98% limit switch of the second, third, and fourth level repair side doors, accompanied by factors such as operator techniques and reading errors, the size accuracy of the adjustment triggering the 98% limit switch action is not high, and repeated measurements are required.

[0003] At present, there are still some defects in the adjustment operation of 98% limit switches of some traditional EMU sliding doors on the existing market. For example, due to the small operating space of the main lock, personal injury may be easily caused during the application of force or movement of the hand. Fingers may be squeezed if not careful. The use of a screwdriver may easily cause deformation and damage to the lock box mechanism. These phenomena may easily lead to low efficiency and prominent safety hazards during emergency troubleshooting and maintenance operations. In addition, most of the limit device connections are through threaded connections, which are troublesome to disassemble. For this reason, we propose a measuring device for the side door of CRH3 EMU. Utility Model Content

[0007] The functional structure includes a fixing bolt located on the outer surface of the fixed plate, a pull-down plate movably installed on the outer surface of the fixed plate, a limiting plate fixedly installed on the outer surface of the pull rod inside the functional block, a return spring movably installed on the outer surface of the pull rod inside the functional block, a clamping block movably installed on the inner surface of the fixed plate, and a fixing spring fixedly installed on the outer surface of the clamping block.

[0008] Furthermore, an inserting groove is provided on the outer surface of the pull-down plate, and the inner wall of the inserting groove is adapted to the outer surface of the clamping block.

[0009] Furthermore, a limiting groove is provided on the outer surface of the clamping block, and the inner wall of the limiting groove is adapted to the outer surface of the pulling rod.

[0013] Furthermore, the outer surfaces of the fixing plate and the pull-down plate are both L-shaped, and the outer surface of the fixing plate is provided with a fixing groove that is matched with the outer surface of the pull-down plate.

[0014] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0015] The measuring device for the side door of the CRH3 EMU is used. By pressing the pull rod, the pull rod will drive the reset spring to contract, and the inclined surface at the bottom of the pull rod will contact the inclined groove inside the clamping block, so that the clamping block moves. When the clamping block moves, it will squeeze the fixed spring on one side to contract. At this time, the clamping block will move out of contact with the lower pull plate, thereby being disassembled, thereby achieving the effect of disassembling the lower pull plate and the fixed plate. The movable upper pull plate is manually adjusted so that the upper pull plate is just stuck on the edge of the outer door frame. After adjustment, it is positioned with the fixing bolts after matching the positions between the tooling parts. , clamp the top of the tooling shell on the side door frame of the vehicle body, then check the 98% limit switch, manually move the door leaf into the secondary locking position, at this time the pneumatic lock does not work, measure and record the distance X from the edge of the door leaf lock box to the edge of the door frame, open the door leaf and then slowly move it to the closed position, when the 98% limit switch is activated, you will hear an activation sound, then stop the movement of the door leaf, measure and record the distance Y from the edge of the door leaf lock box to the edge of the door frame, when XY = -mm, the limit switch position meets the requirements, if not within this range, adjust the position of the limit switch, the measurement result meets the standard requirements, and the measurement is completed.
