[0002] In construction, the connection between passenger and freight elevators and floors is a key task, which involves the safety and efficiency of personnel and material transportation.

[0003] At present, the docking between passenger and freight elevators and floors at construction sites often requires independent scaffolding platforms for docking and transfer. Although the setting of external frames can make passenger and freight elevators move flexibly between the main structures of different floors, the built external frames need to last until the decoration stage, which lasts for a long time. During this period, the materials used for the external frames may rust, age, and other problems, which seriously reduce the construction safety and bring serious safety hazards to the construction work.

[0004] At present, there are also "flip-type" passenger and freight elevators that connect the elevator to the main structure of the building without setting up an additional external frame. The "flip-type" passenger and freight elevator is closer to the building structure and does not require a scaffolding platform. It is also more convenient for people to get on and off and transport building materials. It is one of the commonly used passenger and freight elevators in construction sites.

[0005] However, the "flap-type" passenger and freight elevators currently in use have the following problems: the flap is complicated to install, and the flap needs to be frequently operated to go up and down the construction elevator and transport construction materials.

[0035] The added platform plate 101 is rectangular, and a set of short sides of the added platform plate 101 are provided with guardrails 102;

[0036] A rotating shaft 105 is provided on one long side of the additional platform plate 101; the rotating shaft 105 is mounted on the passenger and freight elevator bottom plate 106, and both ends of the rotating shaft 105 are movably connected to the passenger and freight elevator bottom plate 106 through fixed connectors.

[0037] In this embodiment, the additional platform plate 101 is used to ensure that the gap connection between the passenger and freight elevator and the main structure of the construction building is stable and reliable, thereby reducing the support of independent external frames between the passenger and freight elevator and the main structure; the protective pulls are symmetrically arranged on both sides of the additional platform plate 101 to ensure the safety of people and goods when going up and down the passenger and freight elevator; the fixed connection component 103 is connected to the bottom plate 106 of the passenger and freight elevator.

[0038] The working state of the connecting platform device refers to the state when the connecting platform plate 101 is placed between the passenger and freight elevator and the main structure of the construction building to connect the passenger and freight elevator and the main structure of the construction building. The radial direction is the direction in which the passenger and freight elevator points to the main structure of the construction building.

[0039] As a preferred embodiment of this embodiment, Figure 3 As shown, cavities 501 are respectively provided at both ends of the rotating shaft 105, and spring 504 components are provided in the cavities 501. The rotating shaft 105 is connected to the fixed connection component 103 through the spring 504 components at both ends.

[0040] In order to achieve a better fixing effect of the additional platform plate 101, this embodiment arranges spring 504 components at both ends of the rotating shaft 105, and the spring 504 components are in a compressed state when the additional platform device is working, so that the two ends of the rotating shaft 105 are subjected to the elastic force of the spring 504. Since the rotating shaft 105 is subjected to the elastic force laterally, the connection between the additional platform plate 101 and the passenger and freight elevator can be made firmer, thereby improving the safety of the additional platform device.

[0041] Further preferably, the spring 504 assembly includes a movable end and a spring 504, one end of the spring 504 is connected to the movable end, and the other end of the spring 504 is connected to the rotating shaft 105.

[0056] The working state of the connecting platform device refers to the state when the connecting platform plate 101 is placed between the passenger and freight elevator and the main structure of the construction building to connect the passenger and freight elevator and the main structure of the construction building. The radial direction is the direction in which the passenger and freight elevator points to the main structure of the construction building.

[0057] As a preferred embodiment of this embodiment, Figure 3 As shown, cavities 501 are respectively provided at both ends of the rotating shaft 105, and spring 504 components are provided in the cavities 501. The rotating shaft 105 is connected to the fixed connection component 103 through the spring 504 components at both ends. When the connecting platform device is working, the spring 504 component is in a compressed state.

[0058] In order to achieve a better fixing effect of the additional platform plate 101, this embodiment arranges spring 504 components at both ends of the rotating shaft 105, and the spring 504 components are in a compressed state when the additional platform device is working, so that the two ends of the rotating shaft 105 are subjected to the elastic force of the spring 504.
