Description

Technical Field

[0001] The utility model relates to the technical field of construction hoists, in particular to a flap follow-up structure for a double-door construction hoist. Background Technique

[0002] Modern buildings are gradually becoming complex, diverse, beautiful, and functional. To meet the popularization and application of many new materials, new technologies, new equipment, and new processes, the vertical transportation capacity at the construction site is particularly important. As one of the most common vertical transportation machines at present, the construction hoist is mainly installed in a form attached to the main structure. Since the hoist car must move up and down, it cannot be closely attached to the main structure. Therefore, connecting the construction hoist car and the main structure to fill the gap between them has become one of the key points and difficulties in the installation and later use of the construction hoist.

[0003] In the past construction hoist installation construction, the connection between the car and the main structure was generally carried out by building an external protection frame at the construction hoist opening and laying a jump board on the frame. Its disadvantages are that the construction is complex, it needs to be laid on each floor, the required material cost and labor cost are relatively high, and the construction of building and demolishing the external protection frame is relatively dangerous. Content of the Utility Model

[0004] The utility model aims to solve the above problems, and thus provides a flap follow-up structure for a double-door construction hoist.

[0005] The technical scheme adopted by the utility model to solve the above problems is as follows:

[0006] A flap follow-up structure for a double-door construction hoist car, including a hoist car, an upper door, and a lower door. A flap is hinged to the edge of the hoist car bottom plate. The flap is inclined outward from the hoist car as a whole. Multiple pairs of ear plates are arranged at intervals on the side of the flap away from the hoist car bottom plate. A roller is hinged between the two ear plates of each pair, and the roller abuts against the side of the lower door.

[0007] The utility model adopting the above technical scheme, compared with the prior art, its prominent feature is:

[0008] The utility model has a simple structure, is convenient to use, and has relatively low material cost and labor cost. When in use, since the flap is inclined outward from the elevator car as a whole, the center of gravity of the flap is located on the side of the vertical plane where the hinge point of the flap is located and is close to the lower opening. After the lower opening is opened and moves downward, the flap flips outward from the car under the action of its own weight and lapped with the reinforced concrete floor slab, then the gap between the elevator car of the construction elevator and the main structure can be filled. After use, the lower opening is closed and moves upward, and the flap is lifted and retracted into the elevator car during the movement process. The opening and closing of the flap are completed synchronously with the opening and closing of the double-opening door. There is no need to erect an external protective frame on each layer of the reinforced concrete floor slab and lay a jump board on the frame body, eliminating the possibility of danger during the erection or dismantling process. At the same time, it can be directly transferred to the next construction project with the elevator car for turnover use.

[0009] Preferably, a further technical solution of the utility model is:

[0010] A limiting block is arranged at the bottom of the side of the flap close to the elevator car, so that the center of gravity of the flap is always located on the side of the vertical plane where the hinge point is located and is close to the lower opening; preventing the flap from overflipping and being unable to flip by itself when used next time.

[0011] A plurality of installation grooves are spaced apart at the top surface corners of the lower opening. An ear plate is hinged with a second roller in the installation groove, and the second roller protrudes out of the installation groove toward the side of the lower opening close to the elevator car; reducing the friction between the lower opening and the flap and making the closing process of the lower opening moving upward smoother.

[0012] Protective frames are arranged at both ends of the side of the flap close to the elevator car, and a toe board is arranged between the two vertical rods at the bottom of the protective frame; providing safety protection and preventing accidents when personnel shuttle back and forth between the elevator car and the reinforced concrete floor slab.

[0018] The present utility model will be further described below in conjunction with embodiments. The purpose is only to better understand the content of the present utility model. Therefore, the examples given do not limit the protection scope of the present utility model.

[0019] See Figures 1-3 , a follow-up structure of the flap of a double-door construction elevator car, including an elevator car 1, an upper door, and a lower door 2. A flap 3 is hinged to the edge of the bottom plate of the elevator car 1. The flap 3 is inclined outward from the elevator car 1 as a whole. A plurality of pairs of ear plates 6 are arranged at intervals on the side of the flap 3 away from the bottom plate of the elevator car 1. A roller 7 is hinged between the two ear plates 6 of each pair, and the roller 7 abuts against the side of the lower door 2.

[0020] A limit block 10 is arranged at the bottom of the side of the flap 3 close to the elevator car 1, so that the center of gravity of the flap 3 is always located on the side close to the lower door 2 of the vertical plane where the hinge point is located; to prevent the flap 3 from flipping excessively, so that it cannot flip by itself when used next time.

[0021] A plurality of installation grooves 9 are arranged at intervals at the top corner of the lower door 2. A second roller 8 is hinged in the installation groove 9 through an ear plate arranged, and the second roller 8 protrudes from the installation groove 9 toward the side of the lower door 2 close to the elevator car 1; to reduce the friction between the lower door 2 and the flap 3 and make the closing process of the lower door 2 moving upward smoother.

[0022] Protective frames 4 are arranged at both ends of the side of the flap 3 close to the elevator car 1, and a footrest 5 is arranged between the two vertical bars at the bottom of the protective frame 4; to provide safety protection and prevent accidents when personnel shuttle back and forth between the elevator car 1 and the reinforced concrete floor slab.

[0023] The structure of the present utility model is simple and convenient to use, and the required material cost and labor cost are relatively low. When in use, since the flap is inclined outward from the elevator car as a whole, the center of gravity of the flap is located on the side close to the lower door of the vertical plane where the hinge point of the flap is located. After the lower door is opened and moves downward, the flap flips outward from the car under the action of its own weight and overlaps with the reinforced concrete floor slab, and then the gap between the construction elevator car and the main structure can be filled. After use, the lower door is closed and moves upward, and the flap is lifted and retracted into the elevator car during the movement process. The opening and closing of the flap are completed synchronously with the opening and closing of the double doors. There is no need to set up an external protective frame on each layer of the reinforced concrete floor slab and lay a jump board on the frame body, eliminating the possibility of danger during the erection or demolition process. At the same time, it can be directly transferred to the next construction project with the elevator car for turnover use.

[0024] The above are only the preferred and feasible embodiments of the present utility model, and thus do not limit the scope of rights of the present utility model. Any equivalent changes made by using the content of the specification and drawings of the present utility model are included within the scope of rights of the present utility model.
