[0006] To achieve the above objectives, the present invention adopts the following technical solution: a modular installation auxiliary frame for positioning platform screen doors, comprising a base platform, a door panel moving mechanism, and several support frames. The base platform is equipped with a visual recognition mechanism and drive wheels, and the visual recognition mechanism is connected to a controller. The door panel moving mechanism is mounted on the base platform and is equipped with an electromagnetic adsorption component. The electromagnetic adsorption component is used to generate magnetic force and attract and fix the platform screen door after being energized. The electromagnetic adsorption component is connected to the controller. The support frames are mounted on the base platform and are equipped with a clamping and fixing mechanism. The clamping and fixing mechanism is used to clamp and fix the platform screen door on the support frame. The clamping and fixing mechanism is connected to the controller.

[0007] As an optional embodiment of the above technical solution, the support frame includes a support base plate, a first side frame and a second side frame. The first side frame and the second side frame are arranged opposite to each other on both sides of the support base plate. A limiting groove is provided between the first side frame and the second side frame. The clamping and fixing mechanism is used to restrict the platform door within the limiting groove.

[0008] As an optional implementation of the above technical solution, both the first side frame and the second side frame include an upper frame body and a lower frame body. The upper frame body and the lower frame body are slidably engaged, and a locking mechanism is provided between the upper frame body and the lower frame body.

The surface of the clamping block is provided with a protective pad.

[0012] As an optional implementation of the above technical solution, the supporting base plate is provided with rollers along its length, and the rollers are used to guide the platform door to move along the supporting base plate.

Detailed Implementation

[0020] like Figures 1-3As shown, this embodiment provides a modular installation auxiliary frame for positioning platform screen doors. As an auxiliary device in platform screen door construction, it improves the accuracy and efficiency of platform screen door installation through a more efficient movement and positioning method. The modular installation auxiliary frame includes a base platform 1, a door panel moving mechanism 2, and several support frames 3. The bottom of the base platform 1 is equipped with drive wheels 4, which can move along the subway rails. The base platform 1 is mounted on the drive wheels 4 and is driven by the drive wheels 4 to carry multiple platform screen doors, moving them along the subway rails to the required installation position.

[0021] The base platform 1 is equipped with a visual recognition mechanism connected to a controller. The visual recognition mechanism includes a recognition camera and a camera bracket, with the camera mounted on the base platform 1 via the camera bracket. Typically, visual recognition mechanisms are located at both ends of the base platform 1 to prevent the platform door on the base platform from obstructing the visual recognition mechanism. The two visual recognition mechanisms work together to identify the installation position of the platform door, thereby improving the installation accuracy of the platform door. Specifically, the visual recognition mechanism can compare the current position of the platform door with a pre-set baseline (such as the platform edge) to obtain the deviation between the current position and the target position, guiding the installers to make corresponding position adjustments, which is beneficial for the accurate installation of the platform door. It should be noted that the visual recognition mechanism for identifying the installation position of the platform door is a mature existing technology, and therefore will not be described in detail.

[0022] like Figure 1 As shown, the door panel moving mechanism 2 is mounted on the base platform 1. The door panel moving mechanism 2 is equipped with an electromagnetic adsorption component 5, which generates magnetic force after being energized to attract and fix the platform door. The electromagnetic adsorption component 5 is connected to a controller. After the base platform 1 reaches the appropriate position, the electromagnetic adsorption component 5 attracts and fixes the platform door, and then the door panel moving mechanism 2 is used to move and install the platform door.

[0023] A support frame 3 is mounted on the base platform 1. The support frame 3 is equipped with a clamping and fixing mechanism 6, which is used to clamp and fix the platform screen door to the support frame 3. The clamping and fixing mechanism 6 is connected to a controller. The number of support frames 3 can be set according to specific needs. Each support frame 3 is equipped with a clamping and fixing mechanism 6, which secures the platform screen door to the support frame 3, facilitating the movement of the platform screen door to the installation position. This invention uses the clamping and fixing mechanism 6 to clamp and fix both sides of the platform screen door, preventing the platform screen door from swaying on the support frame 3 and improving the stability of the platform screen door during transport.

[0024] This invention supports the platform screen door using a support frame 3, and clamps and fixes it in place using a clamping and fixing mechanism 6, thereby enabling the platform screen door to be transported and greatly improving its handling efficiency. Simultaneously, the base platform 1 is equipped with a door panel moving mechanism 2 and a visual recognition mechanism. After the platform screen door is transported to the appropriate position, the electromagnetic adsorption component 5 adsorbs and fixes it in place. Then, the door panel moving mechanism 2 is used to move and assist in the installation of the platform screen door. Combined with the visual recognition mechanism, this facilitates precise installation of the platform screen door. This invention integrates the movement, adjustment, and positioning functions of the platform screen door into one unit, reducing the need for repeated use of external measuring tools and greatly improving the installation efficiency and accuracy of the platform screen door.

[0025] like Figure 1 As shown, in this embodiment, the support frame 3 includes a support base plate 7, a first side frame 8, and a second side frame 9. The first side frame 8 and the second side frame 9 are arranged opposite each other on both sides of the support base plate 7. A limiting groove is provided between the first side frame 8 and the second side frame 9. The clamping and fixing mechanism 6 is used to restrict the platform screen door within the limiting groove. The support frame 3 is made of high-strength aluminum alloy profile. The platform screen door is placed in the limiting groove between the first side frame 8 and the second side frame 9, and the clamping and fixing mechanism 6 is used to fix the platform screen door so that it can be moved.

[0026] like Figure 2 As shown, specifically, both the first side frame 8 and the second side frame 9 include an upper frame body 10 and a lower frame body 11. The upper frame body 10 and the lower frame body 11 are slidably engaged, and a locking mechanism 12 is provided between the upper frame body 10 and the lower frame body 11. A clamping and fixing mechanism 6 is provided on the upper frame body 10. The upper frame body 10 can move up and down relative to the lower frame body 11 to adjust the position of the clamping and fixing mechanism 6, so that the clamping and fixing mechanism 6 can clamp and fix the platform door.

[0027] In one specific embodiment, the upper frame 10 includes an upper side plate 13 and two sliding rods 14. The two ends of the upper side plate 13 are connected to the two sliding rods 14 to form a U-shaped structure. The lower frame 11 includes two sliding sleeves, which are spaced apart on the supporting base plate 7. The sliding sleeves are slidably engaged with the sliding rods 14. A clamping and fixing mechanism 6 is provided on the upper side plate 13. By sliding the sliding rods 14 up and down along the sliding sleeves, the position of the upper side plate 13 can be adjusted, which facilitates the adjustment of the position of the clamping and fixing mechanism 6. When it is not necessary to fix the platform door, the upper side plate 13 can be adjusted to the lowest height for easy storage of the upper frame 10.

[0028] Preferably, the locking mechanism 12 includes a matching locking bolt and a locking nut. The sliding sleeve has a fixing hole adapted to the locking bolt, and the sliding rod 14 has multiple adjusting holes adapted to the locking bolt along its length. After the sliding rod 14 is slid up and down along the sliding sleeve to a suitable position, the locking bolt passes through the sliding rod 14 and the sliding sleeve and connects with the locking nut to lock the sliding rod 14, thereby fixing the position of the upper side plate 13 and the clamping and fixing mechanism 6.

[0029] In this embodiment, the clamping and fixing mechanism 6 includes a clamping block 15 and a clamping hydraulic cylinder assembly 16. The clamping hydraulic cylinder assembly 16 is connected to a controller. The fixed end of the clamping hydraulic cylinder assembly 16 is disposed on the upper frame 10, and the movable end of the clamping hydraulic cylinder assembly 16 is connected to the clamping block 15. The surface of the clamping block 15 is provided with a protective pad. The two clamping hydraulic cylinder assemblies 16 drive the corresponding clamping blocks 15 to extend and retract, so that the two clamping blocks 15 clamp and release the platform door. In practical use, the two clamping hydraulic cylinder assemblies 16 first cause the two clamping blocks 15 to retract. After the platform door moves to the limit groove, the two clamping hydraulic cylinder assemblies 16 drive the two clamping blocks 15 to extend, and the two clamping blocks 15 clamp the platform door, which facilitates the transportation of the platform door. After the platform door is transported to the designated position, the electromagnetic adsorption component 5 adsorbs the platform door, and then the two clamping hydraulic cylinder assemblies 16 drive the two clamping blocks 15 to retract, releasing the platform door. At this time, the door panel moving mechanism 2 and the electromagnetic adsorption component 5 are used to move and install the platform door.

[0030] To facilitate the movement of the platform screen door, the supporting base plate 7 is provided with rollers 17 along its length. The rollers 17 guide the platform screen door along the supporting base plate 7. Preferably, both ends of the supporting base plate 7 are provided with guide portions extending to the outside of the first side frame 8 or the second side frame 9, facilitating the transport of the platform screen door and its installation at different stations. The first side frame 8 and the second side frame 9 are both located in the middle of the supporting base plate 7. The guide portions have rollers 17. The platform screen door enters between the first side frame 8 and the second side frame 9 through the guide portions. Its rotation allows it to be easily moved to the limiting groove, and then the clamping and fixing mechanism 6 secures the platform screen door. This design is simple, facilitates the transport of the platform screen door, and effectively saves manpower.

[0031] like Figure 3 As shown, in this embodiment, the electromagnetic adsorption component 5 includes an electrically controlled permanent magnet 18. The electrically controlled permanent magnet 18 is U-shaped and can be attracted to the edge of the platform door. The coil inside the electrically controlled permanent magnet 18 is connected to the controller. The electrically controlled permanent magnet 18 has high safety and can provide reliable fixation for the platform door, eliminating the risk of the platform door falling.

[0032] The electrically controlled permanent magnet 18 has a magnetized state and a demagnetized state. In the magnetized state, a short positive DC pulse is applied to the coil (usually only a few tenths of a second to a few seconds). The magnetic field generated by the coil is in the same direction as the magnetic field of the permanent magnet. The two magnetic fields are superimposed on the working pole surface (suction cup surface) of the electrically controlled permanent magnet 18, generating a very strong total magnetic force. This strong magnetic force can firmly hold the platform door.

[0033] In the demagnetized state, a brief reverse DC pulse is applied to the coil. The magnetic field generated by the coil is opposite in direction to the magnetic field of the permanent magnet. This reverse magnetic field cancels / neutralizes most of the magnetic field of the permanent magnet at its working pole. The magnetic force exerted by the electrically controlled permanent magnet 18 on the steel plate drops sharply to almost zero (leaving only a very small "residual magnetism"). Because the external appearance is non-magnetic (or extremely weakly magnetic), after the platform screen door is installed, it will detach from the electrically controlled permanent magnet 18 under the action of gravity or a very small external force, and the platform screen door will be successfully released.

[0034] This invention uses an electrically controlled permanent magnet 18 to attract platform doors. Power is consumed only momentarily when the state of the electrically controlled permanent magnet 18 is changed; no power is consumed during holding and releasing. Even in the event of a sudden power outage, the platform door will not fall, making it very safe. The magnetization and demagnetization process is fast and controllable, facilitating automation. Moreover, the structure is relatively simple, without complex mechanical moving parts, making it easy to maintain.

[0035] like Figure 1 As shown, the door panel moving mechanism 2 includes a six-axis robotic arm 19 and a lifting mechanism 20. The fixed end of the lifting mechanism 20 is connected to the base platform 1, and the movable end of the lifting mechanism 20 is connected to the fixed end of the six-axis robotic arm 19. The movable end of the six-axis robotic arm 19 is connected to the electromagnetic adsorption component 5. The six-axis robotic arm 19 of this invention has six degrees of freedom, enabling precise adjustment of the platform door in any spatial posture, far exceeding the capabilities of manual adjustment, and effectively improving the installation accuracy of the platform door.

[0036] The lifting mechanism 20 includes a lifting hydraulic cylinder assembly. The bottom end of the lifting hydraulic cylinder assembly is fixed on the base platform 1, and the top end of the lifting hydraulic cylinder assembly is connected to the six-axis robotic arm 19. The lifting hydraulic cylinder assembly is connected to a controller. The controller is used to control the clamping and fixing mechanism 6 to release the platform door after the electromagnetic adsorption component 5 is energized, and to control the lifting hydraulic cylinder assembly to extend so that the platform door moves upward with the electromagnetic adsorption component 5 and disengages from the support frame 3.

[0037] In practical use, this modular installation auxiliary frame requires the platform screen door to first be moved onto the base platform 1. The controller then uses the clamping hydraulic cylinder assembly 16 to retract the two clamping blocks 15, moving the platform screen door onto the support base plate 7. Rollers 17 then move the platform screen door along the support base plate 7 to the appropriate position in the limiting groove. The controller then uses the two clamping hydraulic cylinder assemblies 16 to extend the two clamping blocks 15, which clamp the platform screen door, facilitating its transport. The drive wheels 4 drive the base platform 1 to move. After the platform screen door is transported to the designated location, the controller magnetizes the electro-permanent magnet 18, causing it to firmly hold the platform screen door in place. Then, the controller uses two clamping hydraulic cylinder assemblies 16 to retract the two clamping blocks 15, releasing the platform screen door. At this point, the controller extends the lifting hydraulic cylinder assembly, causing the electro-permanent magnet 18 to lift the platform screen door, pulling it out of the limiting groove. A six-axis robotic arm 19 then moves the platform screen door to the installation position. Combined with a vision recognition mechanism, precise installation of the platform screen door can be achieved. This invention integrates the movement, adjustment, and positioning functions of the platform screen door into one unit, reducing the need for repeated use of external measuring tools and greatly improving the installation efficiency and accuracy of the platform screen door.
