A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature. Specific implementation method one:

[0037] like Figure 1 — Figure 8 As shown, a platform liftable protective net device includes a lifting column, a diamond-shaped lifting mechanism for adjusting the lifting is arranged inside the lifting column, a safety rope 4 is arranged on the diamond-shaped lifting mechanism, and adjacent lifting columns are connected by the safety rope 4 and the protective net 5.

[0038] The working principle and beneficial effects of this embodiment are as follows: the whole set of equipment is composed of multiple groups of lifting columns, multiple safety ropes 4 are installed between the lifting columns, and protective nets 5 are installed between adjacent safety ropes, all of which are installed on the train platform;

[0039] Each set of lifting columns is composed of a front lifting column 1 and a rear lifting column 9, wherein the front lifting column 1 is connected to the right safety rope 4, and the rear lifting column 9 is connected to the left safety rope 4. The front lifting column 1 and the rear lifting column 9 are installed at a certain distance apart so that the left and right safety ropes 4 are on the same straight line.

[0040] A protective net 5 is installed between adjacent safety ropes 4 to enhance the partition effect. It should be noted that the protective net 5 has a connection point with each safety rope 4 so that the force generated by the protective net 5 is evenly distributed to each safety rope 4, reducing the vibration during lifting and lowering and improving the reliability of the device;

[0041] The whole set of equipment is controlled by the PC control center. The staff can operate the remote control to control the lifting guardrail through the control center. It can complete full lifting, full lowering or single lifting. It can also control the full lifting, full lowering and partial lifting of the guardrail through the train identification signal, and obtain the real-time status of the guardrail at the same time.

[0042] When there is an oncoming vehicle, the guardrail will automatically or manually rise to release the isolation status of the platform;

[0044] The above is the working process of the entire automatic lifting equipment of the safety guardrail. Through this equipment, the potential safety hazards of the platform can be minimized. Furthermore, since each lifting column has two lifting systems, each span can be independently lifted and lowered. Even if there is a fault, it will not affect the use and is more reliable. At the same time, the lifting and lowering actions of each span can be automatically completed according to the automatic identification system of the incoming train.

[0048] The working principle and beneficial effects of this embodiment are as follows: the front lifting column 1 and the rear lifting column 9 are symmetrically arranged to form a lifting column, so as to facilitate the driving control of the diamond lifting mechanism for symmetrical use, and thus, since each lifting column has two sets of lifting systems, the independent lifting control of each span is realized, and even if there is a fault, it will not affect the use, and it is more reliable; at the same time, the lifting action of each span can be automatically completed according to the automatic identification system of the incoming train. Specific implementation method three:

[0066] The working principle and beneficial effects of this embodiment are as follows: through the protection net device, a more active role is played in blocking the invasion of foreign objects on the platform. By setting the protection net 5 into a hole shape, the space that can pass through is effectively reduced, which is convenient for deployment and isolation. Specific implementation method nine:

[0068] like Figure 1 — Figure 8 As shown, a platform liftable protective net device is provided, wherein an information display screen 6 is fixed on the fixed column 3, and the information display screen 6 is electrically connected to a telescopic column driver 10 and a diamond structure driver 11 through a controller.

Through the information display screen 6 and the PC controller, the staff can operate the remote control to control the lifting guardrail through the controller; it can complete full lifting, full lowering or single lifting action. It can also control the full lifting, full lowering and partial lifting of the guardrail through the train identification signal, and obtain the real-time status of the guardrail at the same time;

[0070] When a train is approaching, the guardrail automatically or manually rises to release the isolation state of the platform; when the train leaves, the guardrail automatically or manually lowers to enter the isolation state of the platform;

[0071] The above is the working process of the entire safety guardrail automatic lifting device. Through this device, the safety hazards of the platform can be minimized;
