Description

Technical Field

[0001] The utility model relates to the technical field of subway clearance detection, in particular to an operation trolley which is convenient for measuring and adjusting the clearance of platform doors of a subway straight station. Background Art

[0002] The subway limit detection is to provide effective safety guarantee for the new track to be completed and opened to traffic. It mainly detects the equipment limit, which is determined by considering various factors, such as the safety margin of cable brackets, fire-fighting equipment, signal equipment, contact network brackets, advertising boxes, platforms, platform directional signs, etc. All other installed equipment must not intrude into the equipment limit to ensure the absolute safety of vehicle operation.

[0003] The patent with announcement number CN221349928U discloses a new type of subway limit detection device. When in use, the staff adjusts the position of the second limit plate between the two detection structures according to the vehicle limit and equipment limit requirements, so that the two detection structures can meet the detection requirements of the vehicle limit or the equipment limit respectively, and by turning each handle, the corresponding turning rod and gear are rotated, thereby driving the first cross bar meshing with the gear to slide in the slide groove, and then driving the second limit plate to move. The second limit plate is connected to the mounting rod through a spring hinge, and the second limit plate in the detection structure is adjusted according to the requirements. The position is to meet the various size inspections of subway tunnels, platforms and various maintenance platforms in the vehicle depot, and detection structures are set on the front and rear sides of the mounting frame. Push the handle to move the frame, and the pushing staff on both sides observe the collision situation of the second limit plates at the bottom on both sides, and the staff on the platform observe the collision situation of the second limit plates at the top on both sides and the first limit plates. The staff on the station board at a suitable height observes the overall situation in the middle and is responsible for adjusting the detection structure. The detection structure for detecting the vehicle limit is on the side of the traveling direction of the mounting frame, so that the vehicle limit and the equipment limit can be detected at the same time. When this device is in use, the staff must not only push the frame to move, but also observe the collision situation below the second limit plates on both sides. Therefore, when the second limit plate has a slight collision and shakes, the staff's attention is distracted when pushing the frame, causing the staff to ignore the slight shake of the second limit plate, thereby affecting the accuracy of the limit detection result. In addition, the design of the spring hinge can make the second limit plate automatically return to its original position after contacting an object. When this design is excessively worn, the rebound of the second limit plate is hindered, causing the second limit plate to be unable to accurately detect the limit, thereby causing deviations in the detection results.

[0004] In view of this, in the process of limit detection, improving the accuracy of measurement results has become a technical problem that technical personnel in this field need to solve urgently. Utility Model Content
