Description

Technical Field

[0001] This utility model relates to the field of lifting device technology, specifically a double-check device for subway driver door closing. Background Technology

[0002] With the rapid development of China's economy and the continuous increase in the population of major cities, the demand for urban rail construction is increasing day by day. Rail transit, with its characteristics of speed, punctuality and large capacity, is being adopted by more and more cities to solve traffic congestion problems. During the operation of the subway, the doors need to be opened and closed frequently. The subway doors are generally two doors that move relative to each other to open and close the doors. Therefore, before the subway runs, the driver needs to use a double inspection device to check the pressure of the doors.

[0003] Currently, existing dual-inspection devices generally require the driver to manually place the detection head of the device in the middle of the door, and then close the door to squeeze the detection head for testing. During the testing process, due to the driver's subjective operation, it is impossible to accurately place the detection head in the middle of the side door, which can easily cause the detection head to shift when the door squeezes the detection head. At the same time, the detection head becomes unstable during the squeezing process, which will cause errors in the data of the subway car door dual inspection, thereby reducing the accuracy of the door pressure detection. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a double-check device for subway car door closing, which solves the problems of easy deviation and instability in traditional double-check devices during use. This prevents the detection head from deviating during the detection process and improves the stability of the detection head, thereby reducing the detection error of the subway car door double-check device and improving the detection accuracy of the door closing double-check device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-check device for subway driver door closing, comprising a base, a sliding groove I on the upper surface of the base, a movable frame connected to the inside of the sliding groove I via an adjustment mechanism, the movable frame being located on the upper surface of the base, a sliding rod slidably connected inside the movable frame, a limit groove on the side surface of the sliding rod, a limit mechanism on one side of the limit groove, a movable plate fixedly connected to the upper end of the sliding rod, a detector fixedly connected to the upper surface of the movable plate, a detection head on one side of the detector, the side surface of the detection head being fixedly connected to the side surface of the movable plate via a positioning frame, pressure sensors fixedly installed inside both ends of the detection head, a collar on one side of the pressure sensor, the collar slidably installed inside the detection head, a buffer block fixedly connected to one end of the collar, a groove matching the side of the car door on the outer surface of the buffer block, a pressure plate fixedly installed inside the other end of the collar, the pressure plate being aligned with the pressure sensor, and a support frame fixedly connected to both sides of the movable frame, a measuring mechanism being provided inside the support frame.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5 This utility model provides a technical solution: a double-inspection device for subway driver door closing, including a base 1. A sliding groove I 101 is formed on the upper surface of the base 1. A movable frame 2 is connected inside the sliding groove I 101 via an adjustment mechanism. The movable frame 2 is located on the upper surface of the base 1. A sliding rod 202 is slidably connected inside the movable frame 2. A limiting groove 203 is formed on the side surface of the sliding rod 202. A limiting mechanism is provided on one side of the limiting groove 203. A movable plate 4 is fixedly connected to the upper end of the sliding rod 202. A detector 401 is fixedly connected to the upper surface of the movable plate 4. A detection head 403 is provided on one side of the detector 401. The side surface of the detection head 403 is open to... The positioning frame 402 is fixedly connected to the side surface of the moving plate 4. Pressure sensors 408 are fixedly installed inside both ends of the detection head 403. A collar 405 is provided on one side of the pressure sensor 408. The collar 405 is slidably installed inside the detection head 403. A buffer block 404 is fixedly connected to one end of the collar 405. A groove matching the side of the car door is opened on the outer surface of the buffer block 404. A pressure plate 406 is fixedly installed inside the other end of the collar 405. The pressure plate 406 is aligned with the pressure sensor 408. A support frame 301 is fixedly connected to both sides of the moving frame 2. A measuring mechanism is provided on the inner side of the support frame 301.

[0020] As a technical optimization of this utility model, the measuring mechanism includes a take-up roller 302. The two ends of the take-up roller 302 are rotatably connected to the inner surface of the support frame 301. One end of the take-up roller 302 is fixedly connected to a coil spring 3, and a measuring belt 303 is wound around the side surface of the take-up roller 302. The distance between the detection head 403 and the door frame can be measured through the measuring belt 303 in the measuring mechanism, so it is convenient to observe whether the detection head 403 is centered.

[0021] As a technical optimization of this utility model, the adjustment mechanism includes a lead screw 103. One end of the lead screw 103 is rotatably connected to the inner wall of the slide groove I 101. A moving block 104 is symmetrically threaded onto the side surface of the lead screw 103. A support plate 105 is connected to the upper surface of the moving block 104. The upper end of the support plate 105 is fixedly connected to the lower surface of the moving frame 2. One end of the lead screw 103 passes through the base 1 and is fixedly connected to a knob 102. Through the cooperation of the lead screw 103, knob 102, moving block 104, and support plate 105 in the adjustment mechanism, the position of the moving frame 2 can be easily adjusted, thus facilitating the adjustment of the detection head 403 to be centered in the middle of the subway car door.

[0022] As a technical optimization of this utility model, the limiting mechanism includes a slide groove II 205. A limiting slider 207 is slidably connected inside the slide groove II 205. A push rod 204 is fixedly connected to the upper surface of the limiting slider 207. A spring I 206 is fixedly connected to one end of the limiting slider 207. One end of the spring I 206 is fixedly connected to the inner wall of the slide groove II 205. Through the cooperation between the limiting slider 207 and the spring I 206 and the limiting groove 203 in the limiting mechanism, the sliding rod 202 can be limited, thus preventing the sliding rod 202 from raising the moving plate 4 to a certain height and preventing it from falling.

[0023] As a technical optimization of this utility model, the other end of the collar 405 is fixedly connected to a spring II 407. One end of the spring II 407 is fixedly connected to the inner wall of the detection head 403. The collar 405 can facilitate the reset of the buffer block 404 after the detection head 403 is squeezed, thus facilitating the next use.

[0024] As a technical optimization of this utility model, two protruding strips are symmetrically fixedly connected to the side surface of the slide bar 202, and two grooves adapted to the protruding strips are opened inside the movable frame 2. By the cooperation between the protruding strips and the adapted grooves, the slide bar 202 can be further limited to prevent the slide bar 202 from rotating during the detection process.

[0025] In use, the base 1 is first placed inside the subway door. Then, the two ends of the detection head 403 are aligned with the subway door. The operator then pulls the measuring belt 303 on the side surface of the take-up roller 302 so that one end of the measuring belt 303 contacts the door frame. After that, the operator observes whether the distances from both sides of the moving frame 2 to the door are the same. If they are the same, the door can be opened and closed to squeeze the buffer blocks 404 at both ends of the detection head 403. If the distances are not the same, the operator needs to rotate the knob 102. The knob 102 drives the lead screw 103 to rotate, and the lead screw 103 drives the moving frame 2 to move through the moving block 104 and the support plate 105 until the distances from both sides of the moving frame 2 to the door frame are the same. Then, the door is opened to squeeze the buffer block 404. The buffer block 404 will squeeze the pressure sensor 408 through the pressure plate 406 at the other end of the collar 405. At this time, the pressure sensor 408 will display data and transmit it to the detector 401.
