Description

Technical Field

[0001] The utility model relates to the technical field of construction elevators, in particular to a car flap structure of a construction elevator. Background Art

[0002] Modern buildings are becoming increasingly complex, beautiful, and fully functional. In order to meet the popularization and application of many new materials, new technologies, new equipment, and new processes, the vertical transportation capacity of the construction site is particularly important. As one of the most common vertical transportation machinery at present, the construction elevator is mainly installed in the form of being attached to the main structure. Since the elevator car must move up and down, it cannot fit tightly with the main structure. Therefore, connecting the construction elevator car with the main structure and filling the gap between them becomes one of the key and difficult points in the installation and later use of the construction elevator.

[0003] In previous construction elevator installation construction, the connection between the car and the main structure generally adopts a construction method of setting up an external protective frame at the construction elevator entrance and laying a springboard on the frame. The disadvantage is that the construction is complicated and needs to be laid on each floor. The material cost and labor cost are high, and the erection and dismantling of the external protective frame are highly dangerous. Utility Model Content

[0004] The utility model aims to solve the above problems, thereby providing a construction elevator car flap structure.

[0005] The utility model solves the above problems and adopts the following technical solutions:

[0006] A construction elevator car flap structure includes an elevator car, a load-bearing steel plate is vertically arranged on the edge of the elevator car bottom plate and connected to the bottom plate through a hinge, the load-bearing steel plate is flipped to the outside of the elevator car and overlapped with the reinforced concrete floor slab, and protective parts are arranged on both sides of the top surface of the load-bearing steel plate.

[0007] Compared with the prior art, the utility model adopting the above technical solution has the following outstanding features:

[0008] The utility model has a simple structure and is easy to use, and the required material cost and labor cost are low. When in use, it is only necessary to flip the load-bearing steel plate to the outside of the elevator car and overlap it with the reinforced concrete floor slab to complete the filling of the gap between the construction elevator car and the main structure. After use, it is retracted into the elevator car, and the operation is relatively convenient. There is no need to set up external protective frames on the reinforced concrete floors of each layer and lay springboards on the frame, which eliminates the possibility of danger during the erection or dismantling process. At the same time, the utility model can be directly transferred with the elevator car to the next construction project for turnover use.

[0009] As a preferred embodiment, a further technical solution of the utility model is:

[0010] The protection part comprises a rectangular protection frame, and a foot plate is arranged between two vertical rods at the bottom of the protection frame.

[0011] It also includes the upper door and the lower door of the double door of the elevator car. A linkage part that is linked to the double door of the elevator car is provided at the bottom of the load-bearing steel plate. The linkage part includes a steel wire rope and a fixed pulley. The fixed pulley is fixed to the bottom of the lower door of the double door of the elevator car. The steel wire rope is wound around the fixed pulley, one end of which is fixedly connected to the load-bearing steel plate, and the other end of which is upwardly penetrated through the bottom plate of the elevator car and then connected to the upper door of the double door of the elevator car.

[0016] The present invention is further described below in conjunction with embodiments, the purpose of which is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

[0017] See also Figure 1-Figure 3 A construction elevator car flap structure includes an elevator car 9, a load-bearing steel plate 1 is vertically arranged on the edge of the bottom plate 10 of the elevator car 9, and is connected to the bottom plate 10 through a hinge 2. The load-bearing steel plate 1 is flipped to the outside of the elevator car 9 and overlapped with the reinforced concrete floor 11, and protective parts are arranged on both sides of the top surface of the load-bearing steel plate 1.

[0018] The protection part comprises a rectangular protection frame 3, and a foot plate 5 is arranged between two vertical rods at the bottom of the protection frame 3 to improve the safety of people passing through.

[0019] It also includes an upper door 8 and a lower door 7 of the double doors of the elevator car. A linkage part that is linked to the double doors of the elevator car is provided at the bottom of the load-bearing steel plate 1. The linkage part includes a steel wire rope 4 and a fixed pulley 6. The fixed pulley 6 is fixed to the bottom of the lower door 7 of the double doors of the elevator car. The steel wire rope 4 is wound around the fixed pulley 6, one end of which is fixedly connected to the load-bearing steel plate 1, and the other end of which is upwardly penetrated through the bottom plate 10 of the elevator car 9 and then connected to the upper door 8 of the double doors of the elevator car.

[0020] During the use of the utility model, when personnel need to pass between the reinforced concrete floor 11 and the elevator car 9, the double doors of the elevator car need to be opened. During the opening of the double doors of the elevator car, the upper door 8 and the lower door 7 move upward and downward respectively, and through the cooperation of the steel wire rope 4 and the fixed pulley 6, the load-bearing steel plate 1 is pulled to flip toward the outside of the elevator car 9 to achieve linked opening. After the load-bearing steel plate 1 is flipped, it overlaps the reinforced concrete floor 11, and personnel can pass over the load-bearing steel plate 1; when the double doors of the construction elevator car need to be closed, the personnel simultaneously pull the protective frame 3 toward the inside of the construction elevator car 9 to recycle the load-bearing steel plate 1.

[0021] The utility model has a simple structure and is easy to use, and the required material cost and labor cost are low. When in use, it is only necessary to flip the load-bearing steel plate to the outside of the elevator car and overlap it with the reinforced concrete floor slab to complete the filling of the gap between the construction elevator car and the main structure. After use, it is retracted into the elevator car, and the operation is relatively convenient. There is no need to set up external protective frames on the reinforced concrete floors of each layer and lay springboards on the frame, which eliminates the possibility of danger during the erection or dismantling process. At the same time, the utility model can be directly transferred with the elevator car to the next construction project for turnover use.
