3. The telescopic lifting platform door system adapted for multiple network integration according to claim 1, wherein the support means are provided with guide slots arranged in parallel in a vertical direction, and the first and second door bodies slide up and down in the respective guide slots, respectively.
4. A lifting telescopic platform door system to accommodate multiple network integration according to claim 1 wherein the drive means includes a drive motor and a screw, one end of the screw being connected to the drive motor and the other end passing through the first connector, the connection being by screw thread.
5. The lifting type telescopic platform door system suitable for multi-network fusion of claim 1, wherein one end of each of the first and second transmission bars, which bypasses the first and second guide wheels, is provided with a counterweight, and the sum of the weights of the counterweights is not less than the weight of the telescopic door body.
6. A telescopic lifting and lowering platform door system to accommodate multiple network convergence as claimed in claim 1, wherein the first and second guide wheels are sprockets, the first and second belts are chains, and the sprockets engage with the chains respectively.
7. A multi-network compatible lifting and nesting platform door system according to claim 1, further comprising at least one third door body, wherein a third guide wheel is coaxially and fixedly disposed on said transmission guide wheel corresponding to said third door body, and said driven lifting unit is disposed corresponding to said third guide wheel.
8. The elevating telescopic platform door system adapted for multiple network convergence of claim 1, wherein the telescoping door bodies have a manual control push rod and an emergency door opening button on the track side.
9. The elevating telescopic platform door system adapted for multiple network integration of claim 1, wherein a non-sensing detection device is fixedly mounted to the lower edge of the first door body.
10. A telescopic lifting platform door system to accommodate multiple networks according to any one of claims 1 to 9, further including a sealing cover panel telescopically arranged in parallel with the first and second door bodies, the sealing cover panel being fixedly connected to the civil structure at the top of the platform door by a sealing joint, the upper edge of the first door body overlapping or flush with the sealing cover panel when the telescopic door bodies are fully deployed, thereby forming a fully enclosed platform door structure.
