[0025] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0026] Example: Figure 1 , 2 As shown in Figures 3, 4 and 5, the railway platform protection safety guardrail of this embodiment includes a box body 1, a lifting frame 2, a first lifting mechanism 3 and a plurality of rope connectors 4. The lifting frame 2 can be slidably assembled in the box body 1, and a hole for the lifting frame 2 to pass through is provided on the top of the box body 1. The first lifting mechanism 3 is installed in the box body 1 and connected to the lifting frame 2. The plurality of rope connectors 4 are installed on one side of the lifting frame 2 at intervals in the upper and lower directions. A channel vertically passing through the side end of the box body 1 is provided, and the channel is connected to the interior of the box body 1 and the above-mentioned holes.

[0027] The usage process is as follows:

[0028] Generally, two or more railway platform protection safety guardrails are spaced along the edge and length of the platform, and each group of two railway platform protection safety guardrails has passages arranged opposite to each other and fixedly assembled on the platform ground. The multiple rope connectors 4 of the two railway platform protection safety guardrails correspond to each other, and a horizontal protection rope (indicated by A in the figure) is connected between the two corresponding rope connectors 4. In the protection state: the lifting frame 2 is retracted in the box 1, and the two boxes 1 are intercepted by multiple protection ropes spaced up and down. Generally, the tension of each protection rope exceeds 1 ton. In this way, before the train arrives at the station, the interception of multiple protection ropes can play a protective role against the possibility of people or luggage falling on the platform. When the train arrives at the station, the two first lifting mechanisms 3 of each group synchronously drive the lifting frame 2 to rise, thereby driving the multiple rope connectors 4 and the protection ropes to rise and fall, and a passage for people to pass through will be formed between the two boxes 1. After everyone gets on the train, the first lifting mechanism 3 drives the lifting frame 2 to fall again, and the protection interception can be re-formed. The whole device has a reasonable structural design and can provide good safety protection. At the same time, it is also convenient for people to pass normally when it is raised.

[0029] Of course, in this embodiment, if Figure 2 As shown, a channel can be set at both side ends of the box body 1, and two independent chambers are set in the box body 1. Each chamber is connected to a channel, and each chamber is provided with a set of lifting frames 2, a first lifting mechanism 3 and multiple rope connectors 4, so that the protective ropes can be connected to the two sides of the box body 1 respectively.

[0030] As a preferred embodiment, a vertically extending fixing frame 11 is provided on a side wall inside the box body 1, a vertically extending first optical axis 12 is provided on one side of the fixing frame 11, and the other side of the lifting frame 2 is slidably mounted on the first optical axis 12 via a first slider.

[0031] In the above embodiment, the design of the fixing frame 11 and the first optical axis 12 is mainly for the convenience of installing the lifting frame 2. The other side of the lifting frame 2 is mounted on the first optical axis 12 through the first slider, and the first lifting mechanism 3 drives the lifting frame 2 to rise and fall smoothly along the first optical axis 12. The whole structure is simple in design, and the lifting frame 2 is smoother and has less resistance.

[0032] As a preferred embodiment, Figure 4 and 5As shown, the first lifting mechanism 3 includes a driving sprocket 31, a passive sprocket 32, a first chain 33 and a rotation driving device 34. The rotation driving device 34 is installed on the inner bottom wall of the box body 1. The driving sprocket 31 is transmission-connected with the rotation driving device 34. The passive sprocket 32 ​​is rotatably installed on the upper end of the fixed frame 11 through a wheel axle. The first chain 33 surrounds the driving sprocket 31 and the passive sprocket 32 ​​and engages with the driving sprocket 31 and the passive sprocket 32. A first clamping plate 35 is provided on one of the vertical sections of the first chain 33. The first clamping plate 35 is connected and fixed to the lifting frame 2.

[0033] In the above-mentioned implementation scheme, the box body 1 is a rectangular box body as a whole, and the two larger sides of the box body 1 are respectively facing the platform (that is, towards the width direction of the train track), and the driving sprocket 31 and the passive sprocket 32 ​​are respectively installed on the side ends of the fixed frame 11 through the wheel axle and the bracket rotatably connected to the wheel axle. The fixed frame 11 adopts a rectangular frame frame or a plate-shaped profile with a certain width. The rotating drive device 34 drives the driving sprocket 31 to rotate, which can drive the first chain 33 and the passive sprocket 32 ​​to run. During the operation of the first chain 33, the lifting frame 2 is driven to rise and fall through the first clamping plate 35 connected to its vertical section. The lifting of the entire lifting frame 2 adopts a chain transmission structure, and the operation is relatively stable.

[0034] In this embodiment, the rotation driving device 34 is a conventional servo motor or a stepping motor.

[0035] As a preferred embodiment, a controller is disposed in the box 1, the controller is connected to the motor and is externally connected to a power source, and a control button 14 connected to the controller is disposed on the surface of the box 1.

[0036] In the above embodiment, the control button 14 is used to give instructions to the controller, thereby controlling the operation of the rotation drive device 34 (mainly the forward and reverse rotation of the motor), thereby realizing the lifting operation of the lifting frame 2, which is very simple. In this embodiment, two control buttons 14 can be set, one to control the forward rotation of the motor and the other to control the reverse rotation of the motor.

[0037] As a preferred embodiment, a sensor 15 is embedded on the outer surface of the side wall of the box body 1, and an infrared sensor 16 for sensing whether a person is approaching is embedded on the outer surface of the side wall of the box body 1 near the passage. The box body 1 is provided with an alarm, and the infrared sensor 16, the sensor 15 and the alarm are respectively connected to the controller.

[0038] In the above embodiment, the infrared sensor 16 is arranged on the side wall of the box 1 near the passage, and the sensor 15 is arranged on one side of the side wall of the box 1 near the lane. When a train enters the platform, the sensor 15 senses the train entering, and then an alarm is triggered. At the same time, after a certain delay time, the controller controls the lifting frame 2 to rise. When the lifting frame 2 is not raised, if a passenger approaches the box 1 and is detected by the infrared sensor 16, the controller controls the alarm to sound. This achieves a certain degree of automated operation and alarm.

[0039] It should be additionally explained that: in this embodiment, the sensor 15 is a conventional proximity sensor.

[0040] Of course, one or more pairs of photoelectric sensors can be set on the side close to the two railway platform protection safety guardrails. When a passenger enters the area between the two railway platform protection safety guardrails, the controller can control the alarm to sound.

[0041] As a preferred embodiment, one side of the lifting frame 2 is equipped with a vertically extending second optical axis 21, and all the rope connectors 4 except the top one are slidably mounted on the second optical axis 21 through second sliders, the top rope connector 4 is connected and fixed to the lifting frame 2, adjacent second sliders or adjacent rope connectors 4 are connected through flexible connectors, and a second lifting mechanism 5 is provided at the side end of the lifting frame 2, and the second lifting mechanism 5 is connected to the bottom one of the second sliders.

[0042] In the above embodiment, when the lifting frame 2 is retracted in the box 1, multiple rope connectors 4 are arranged equidistantly from top to bottom (the spacing is generally designed to be 150mm, with a large spacing density, which can block medium and large items and luggage). When the train stops at the platform and the crowd is about to get on the train, the first lifting mechanism 3 drives the lifting frame 2 to rise to the upper limit position. At the same time, the second lifting mechanism 5 drives the second slider at the lowest rope connector 4 to move upward along the second optical axis 21. During the movement, it contacts the upper second slider one by one and pushes the second slider upward, that is, the upper rope connectors 4 are pushed upward one by one to the uppermost rope connector 4, so that the spacing between multiple rope connectors 4 and protective ropes becomes smaller and closer. In this way, when the lifting frame 2 rises to the highest position, the protective ropes are gathered together, leaving a relatively spacious passage for pedestrians to pass through. In this way, the height of the box 1 can be reduced. The box 1 can be designed to be about 1.2m high so that most passengers can pass through and get on the train smoothly. When the lifting frame 2 needs to be lowered to resume its protective function, the second lifting mechanism 5 drives the lowest rope connector 4 to move downward and return to its original position, and the multiple rope connectors 4 above it (except the highest one) are pulled downward and returned to their original positions by the rope connector, or moved downward and returned to their original positions under the action of gravity. The overall structural design is reasonable and very clever, which can effectively reduce the design size of the box 1 and ensure good passage for passengers after the lifting frame 2 is raised.

[0043] In this embodiment, the flexible connecting member is a wire rope.

[0044] In this embodiment, the rope connector 4 can adopt a conventional hook, which is connected to the knotted rope ring at the end of the protective rope. The hook is fixed on a mounting plate, and the mounting plate is mounted on the second optical axis 21 through a second slider.

[0045] As a preferred embodiment, Figure 4 and 5 As shown, the second lifting mechanism 5 includes two transmission sprockets 51 and a second chain 52. The two transmission sprockets 51 are rotatably mounted on the upper and lower sides of the side ends of the lifting frame 2 through wheel axles, respectively. The second chain 52 surrounds the two transmission sprockets 51 and engages with the two transmission sprockets 51 respectively. A second clamping plate 53 is provided on one of the vertical sections of the second chain 52. The second clamping plate 53 is connected and fixed to the upper end of the fixed frame 11. A third clamping plate 54 is provided on the other vertical section of the second chain 52. The third clamping plate 54 is connected and fixed to the lowermost second slider.

[0046] In the above embodiment, when the lifting frame 2 is retracted in the box 1, the first clamping plate 35 is at the bottom, the second clamping plate 53 is at the top, and the third clamping plate 54 is also at the bottom. When the rotary drive device 34 drives the first chain 33 to operate, the first clamping plate 35 moves upward and drives the lifting frame 2 to rise. At the same time, the second clamping plate 53 moves downward, which will pull the second chain 52 to operate. When the second clamping plate 53 moves downward, the third clamping plate 54 moves upward, which will drive the second slider connected thereto to move upward along the second optical axis 21, so that when the lifting frame 2 is raised, multiple rope connectors 4 are pushed upward from bottom to top one by one to the rope connector 4 close to the top, that is, multiple protective ropes are moved upward and gathered. The second lifting mechanism 5 is linked with the first lifting mechanism 3, and the design is very clever and the operation is more convenient.

[0047] In this embodiment, eight rope connectors 4 are provided.
