[0030] This embodiment provides a platform safety door lifting device, see reference. Figures 1-10 As shown, the device includes two uprights 1. A pad 11 is provided at the bottom of each upright 1. The pad 11 has multiple mounting holes. A first motor 2 is provided at the upper end of each of the two uprights 1. A turntable 21 is provided on one side of each first motor 2. The first motor 2 and the turntable 21 are connected in a transmission manner. The upright 1 is hollow inside. A sling 3 is provided inside the upright 1. One end of the sling 3 is connected to the turntable 21. The other end of the sling 3 is connected to a pull plate 4. One end of the pull plate 4 extends out of the upright 1 through an elongated hole 12 opened in the side wall of the upright 1. The extended end of the pull plate 4 is connected to the bottom end of a vertical rod 5. A flexible pull strap 51 is connected to the vertical rod 5.

[0031] In the above embodiment, a pad 11 is provided at the bottom of the upright 1, and the pad 11 has multiple mounting holes for inserting fixing bolts, so that the bottom end of the upright 1 is connected to the ground. Two uprights 1 are respectively set at the reserved opening of the safety gate of the platform railing. A first motor 2 is installed at the upper end of the upright 1, and a turntable 21 is provided on one side of the first motor 2. The first motor 2 and the turntable 21 are connected in a transmission connection, and the first motor 2 can drive the turntable 21 to rotate in both directions. Further, the upright 1 is hollow inside, and a sling 3 is provided inside the upright 1. One end of the sling 3 is connected to the turntable 21, and the other end of the sling 3 is connected to the pull plate 4. Figure 6 As shown, one end of the pull plate 4 extends out of the upright 1 through an elongated hole 12 in the side wall of the upright 1. The elongated hole 12 is set along the vertical direction of the upright 1. The turntable 21 is driven to rotate by the first motor 2. The forward and reverse rotation of the turntable 21 retracts and extends the sling 3, so that the sling 3 pulls the pull plate 4 to move up and down in the vertical direction of the upright 1. The extended end of the pull plate 4 is connected to the bottom end of the upright 5. Multiple flexible pull straps 51 are connected to the upright 5 to block and close the passage space between two uprights 5. It should be noted that... The two vertical bars 5 and the multiple flexible straps 51 connecting them form a safety gate structure, which can be used to open and close the reserved opening for the safety gate on the platform railing. Specifically, by controlling the first motor 2 to drive the turntable 21, the lifting straps 3 are extended and retracted, and the lifting plate 4 is raised and lowered, thus raising and lowering the vertical bars 5 to open and close the safety gate. Compared to operating the gate panel, this reduces the load on the control mechanism, improves the response speed of the safety gate, and reduces the load on the drive device, thus improving the operating efficiency of the lifting device. Furthermore, the transmission device is located inside the vertical bar 1, meaning the lifting straps 3 move the lifting plate 4 within the vertical bar 1. This prevents passengers from accidentally touching the lifting straps 3 or other transmission mechanisms, which could cause the lifting device to jam, thus improving the stability of the lifting device. When a train travels at high speed, it generates wind pressure. The gaps between the flexible straps 51 can be used to release this wind pressure, reducing the impact of wind pressure on the platform safety gate when the train passes.

[0032] In one embodiment of this application, see reference Figure 5 As shown, a buffer block 41 is connected to the lower part of the pull plate 4.

[0033] In the above embodiment, the buffer block 41 connected to the lower part of the pull plate 4 is made of a soft material such as rubber. When the turntable 21 rotates and lowers the pull plate 4, the buffer block 41 can touch the bottom of the upright 1 before the pull plate 4 to play a buffering role, preventing the pull plate 4 from directly touching the pad 11 at the bottom of the upright 1 and causing the pull plate 4 to deform. This increases the friction of the pull plate 4 sliding in the elongated hole 12, which is beneficial to improving the smoothness of the operation of the lifting device.

[0034] In one embodiment of this application, the flexible tether 51 is made of Kevlar material.

[0035] In the above embodiments, Kevlar has extremely high tensile strength and can withstand huge static and dynamic loads. It is lighter than the pull belt made of traditional materials (such as nylon, polyester or steel wire) of the same volume, which reduces the load on the lifting control mechanism, which is beneficial to improving the response speed of the safety door operation, reducing the load on the lifting drive device, and also beneficial to improving the operating efficiency of the lifting device.

[0036] In one embodiment of this application, see reference Figure 9 As shown, a display screen 6 is connected to the side of the upright 1.

[0037] In the above embodiments, the display screen 6 can be used to intelligently link with the management platform. The background can manually enter temporary train formations and update train information in a timely manner. When there are situations such as train delays, track changes, or train formation changes, the display screen 6 can display notifications in a timely manner. Compared with relying solely on broadcasts for information notification, this is beneficial to improve the timeliness of platform information updates. Information can remain on the display screen 6 for a long time to prevent passengers from missing important travel information.

[0038] In one embodiment of this application, see reference Figure 9 As shown, a support column 61 is provided on the side of the display screen 6.

[0039] In the above embodiment, the upright 1 and the support column 61 are respectively set on both sides of the display screen 6 for installing and fixing the display screen 6, preventing the display screen 6 from shaking due to airflow disturbances generated when the train enters the station, and improving the stability of the display screen 6 installation.

[0040] In one embodiment of this application, see reference Figure 8 As shown, the vertical rod 5 has multiple through holes 52, and fastening bolts 53 are provided on the outside of the through holes 52.

[0041] In the above embodiment, when fixing the flexible pull strap 51, both ends of the flexible pull strap 51 can be inserted into the through holes 52 of the vertical rod 5 and then the fastening bolts 53 can be screwed in to clamp the pull strap in the through holes 52, so as to realize the flexible pull strap 51 is installed between the two vertical rods 5. The structure is simple and convenient for the replacement and maintenance of the pull strap.

[0042] In one embodiment of this application, see reference Figure 10 As shown, a conduit 7 is installed on one side of the upright 1.

[0043] In the above embodiments, the conduit 7 is used to enclose the cable, which protects the power supply cable or control cable of the column and helps to improve the stability of the lifting device.

[0044] In actual use of this application: the first motor 2 installed on the top of the two uprights 1 is a servo motor, which controls synchronous operation during operation. A turntable 21 is provided on one side of the first motor 2, and the first motor 2 is connected to the turntable 21 for transmission. The uprights 1 are hollow and have a sling 3 inside. One end of the sling 3 is connected to the turntable 21, and the other end of the sling 3 is connected to the pull plate 4. One end of the pull plate 4 extends out of the upright 1 through an elongated hole 12 opened in the side wall of the upright 1. The elongated hole 12 is set along the vertical direction of the upright 1. The first motor 2 drives the turntable 21 to rotate. The turntable 21 rotates forward and backward to retract and extend the sling 3, so that the sling 3 pulls the pull plate 4 to move up and down in the vertical direction of the upright 1. The extended end of the pull plate 4 is connected to the bottom end of the upright 5. Multiple flexible pull straps 51 are connected to the upright 5 to block and close the passage space between two uprights 5. By controlling the first motor 2 to drive the turntable 21 to retract and extend the sling 3, the pull plate 4 is raised and lowered, which drives the upright 5 to raise and lower, so as to realize the opening and closing of the safety door.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
