On the contrary, the embodiments of the present application include all variations, modifications and equivalents falling within the spirit and scope of the appended claims.

[0029] The embodiments of the utility model are explained in detail below in combination with the drawings.

[0030] As Figure 1 shown, the utility model discloses a lifting type platform safety protection device, including pedestal 2, at least one lifting column 1 in pedestal 2 and the isolation assembly arranged on lifting column 1, lifting column 1 is connected through first transmission mechanism with pedestal 2, and isolation assembly is connected through second transmission mechanism with lifting column 1, the front chamber and rear chamber are formed in pedestal 2 through the partition, first guide rail 3 is arranged on the side wall of front chamber, and lifting column 1 is slidably connected with first guide rail 3 through first sliding block, the rear chamber is equipped with counterweight block 6, wherein the top of pedestal 2 is equipped with driving device and the connecting sprocket connected with driving device, one end of connecting sprocket is connected with sliding block, and the other end is connected with lifting column 1, and lifting column 1 is lifted or lowered through the rotating direction of driving device.

[0031] The height of pedestal 2 in the embodiment is preferably 1.45m, the width is preferably 0.4m, the distance between adjacent two pedestals 2 is between 15-30m, and in addition, long holes are arranged on the two sides of pedestal 2, the long holes are used for isolation rope to pass out, so as to realize platform isolation, and in the embodiment, pedestal 2 can be equipped with two lifting column 1 structures or one lifting column 1 structure, and two lifting column 1 structures can be installed in the middle, so as to reduce installation cost.

[0032] The driving device includes a drive motor 9 and a drive shaft connected to the output end of the drive motor 9. A drive gear 8 is mounted on the drive shaft, and the drive gear 8 is connected to a driven gear 7 on a driven shaft via a first sprocket. The driven shaft also has a connecting gear, on which a connecting sprocket is mounted. The drive shaft is connected to the motor output end via a coupling, and one end of both the drive shaft and the driven shaft is mounted on a shaft seat. A second guide rail is provided on the inner wall of the rear cavity, and the counterweight 6 has a guide rail groove that matches the second guide rail. This embodiment is an example. Figures 2 to 4 As shown, the specific usage process is as follows: the drive motor 9 rotates, the drive shaft rotates, which drives the drive gear 8 to rotate, which in turn drives the driven gear 7 via the first sprocket to rotate. The driven gear 7 rotates, which in turn drives the driven shaft to rotate, which in turn drives the connecting gear to rotate. Since the connecting gear is equipped with a connecting sprocket, the connecting sprocket is wound around the connecting sprocket. At the same time, the top of the base 2 has two openings, which are located at both ends of the connecting gear, for the two ends of the connecting sprocket to pass through and connect to the lifting column 1 in the front chamber and the counterweight 6 in the rear chamber, respectively. When the drive motor 9 rotates forward, the lifting column 1 rises and the counterweight 6 falls; when the drive motor 9 rotates in reverse, the lifting column 1 falls and the counterweight 6 rises. In this embodiment, the lifting of the lifting column 1 is balanced by the weight of the counterweight 6, so that the drive motor 9 only needs a small amount of power to drive the lifting column 1 to rise and fall, which has a good energy-saving effect.

[0033] The isolation component includes at least one isolation block 5 and isolation ropes disposed on the isolation block 5. In the embodiment, there are multiple isolation blocks 5, with each counterweight 6 spaced apart, and preferably each counterweight 6 is provided with three isolation ropes.

[0034] The second transmission mechanism includes a rack 4 and a first gear 11 meshing with the rack 4. The first gear 11 is connected to a second gear 17 located at the top of the lifting column 1 via a chain 12. The isolation block 5 is connected to the chain 12 via a connecting clamp. The isolation block 5 is slidably connected to a third guide rail 13 located on both side walls of the lifting column 1 via a second slider. The rack 4 is located on the inner wall of the front cavity of the base 2, and the first gear 11 is located at the bottom of the lifting column 1. Figure 5 As shown, the bottom of the lifting column 1 is provided with a first gear 11. When the lifting column 1 rises, the first gear 11 will move along the meshing rack 4. At the same time, since the first gear 11 is fitted with a chain 12, the chain 12 rotates. The rotation can drive the connected isolation block 5 to move through the connecting clamp.

[0035] It also includes multiple limiting blocks 14, each of which is arranged at intervals along the length of the lifting column 1, such as... Figure 5 or Figure 6The limiting block 14 in the embodiment is used to support and limit the isolation block 5. One isolation block 5 is arranged between each pair of adjacent limiting blocks 14. The spacing between the limiting blocks 14 is the movement stroke of the isolation block 5. In this embodiment, a stroke switch is arranged at the position corresponding to each limiting block 14, which is used to identify the movement stroke of each isolation block 5. When the isolation block 5 moves to the set stroke, the driving motor 9 stops.

[0036] The isolation block 5 is provided with a connecting bolt 15 at one end and an adjusting mechanism 16 for adjusting the tension of the isolation rope at the other end. Figure 6 Figure 7 As shown in the figure, the right end of the isolation block 5 is preferably provided with three connecting bolts 15. Each connecting bolt 15 is provided with an isolation rope. As shown in the figure, Figure 6 The adjusting mechanism 16 at the left end of the isolation block 5 includes a cover plate and an adjusting column connected to the cover plate. Figure 7 A plurality of adjusting holes are arranged on the isolation block 5 and connected to the adjusting column. When the isolation rope passes around the connecting bolt 15, it continues to pass around the adjusting column and is connected to the device on the other side. When it is necessary to adjust the tension of the isolation rope, as shown in the figure, Figure 7 The position of the adjusting column and the adjusting hole in the adjusting mechanism 16 is selected to adjust the tension of the isolation rope.

[0037] The device also includes a control system that can control the driving device. The control system in the device is provided with a power supply, which is preferably a battery. The control system is a controller. The system obtains the formation condition of the incoming and stopping train according to the train formation identification device. The basic information is fed back to the controller, which controls the driving device to make the isolation rope rise. The device is also provided with an audible and visual warning light. When the device is turned on or off, the audible and visual warning light flashes and emits a warning sound.

[0038] When it is necessary to open the platform entrance and exit to allow passengers to enter, the driving motor 9 rotates in the forward direction, driving the driving gear 8 connected to the driving motor 9 to rotate, thereby driving the driven gear 7 to rotate. The driven gear 7 drives the connecting sprocket on the connecting gear to rotate. At this time, the connecting sprocket drives the lifting column 1 connected thereto to move upward along the first guide rail 3, and the counterweight 6 moves downward along the second guide rail. At the same time, the lifting column 1 moves upward, and the connecting clamp connected to the chain 12 drives the isolation block 5 to move upward through the meshing of the first gear 11 and the rack 4 and the rotation of the chain 12,

[0039] until the stroke switch of the limiting block 14 at the highest point of the lifting column 1 stops. At this time, the device is in the closed state. At this time, the platform entrance and exit are opened, and passengers can enter the train through the platform entrance and exit.

[0040] ​When it is necessary to close the platform entrance and exit, the driving motor 9 rotates reversely, drives the driving gear 8 connected with the driving motor 9 to rotate reversely, thereby driving the driven gear 7 to rotate reversely, the driven gear 7 drives the connecting sprocket on the connecting gear to rotate reversely, and drives the sliding table to move downward along the first guide rail 3, while the counterweight 6 moves upward along the second guide rail, so that the lifting column 1 returns to the base 2; at this time, the isolation blocks 5 move downward until each isolation block 5 contacts the corresponding limiting block 14, the limiting block 14 realizes the support and layered positioning of the isolation block 5, and the isolation rope on the isolation block 5 blocks the platform entrance and exit, so that the passengers cannot approach the platform entrance and exit.
