Description

Technical Field

[0001] This utility model relates to the field of elevator flap doors, specifically a flap door for construction elevators. Background Technology

[0002] Construction hoists are commonly used vertical transportation machines for carrying people and goods in the construction industry. They are also known as construction elevators, passenger and freight elevators, or outdoor elevators. They achieve the lifting and lowering of the cage or platform through a guiding device and are used for vertical transportation needs in projects such as interior and exterior decoration of high-rise buildings, bridges, and chimneys. They typically consist of five main parts: foundation, steel structure (including guide rails and cage), drive device (gear and rack or wire rope lifting), safety device, and electrical system. In existing technologies, after the cage of a construction hoist reaches each floor, there is a large gap between the cage and the floor. To ensure the safe transportation of personnel and materials, scaffolding needs to be erected to get close to the cage. Construction hoists generally use the flip-door in the cage for passage to adapt to the needs of different construction scenarios. However, the flip-doors of existing cages mostly lack protective structures on both sides, making it difficult to protect the workers and goods passing through, resulting in low safety. Summary of the Invention

[0003] To address the shortcomings of existing technologies, such as the lack of protective structures on both sides of the flap doors of existing hoists, which makes it difficult to protect workers and goods passing through and results in low safety, this utility model proposes a flap door for construction hoists.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a flip-door for a construction hoist, including a cage, a flip-door is provided on one side of the cage, and a protective mechanism is provided in the inner cavity of the flip-door; The protective mechanism includes a mounting groove, which is formed on the surface of the flip door. A mounting plate is fixedly connected to the inner cavity of the mounting groove. Two bidirectional threaded rods are rotatably connected to the inner cavity of the mounting plate. Two movable blocks are threadedly connected to the surface of the bidirectional threaded rods. A fixed block is fixedly connected to one side of each movable block. A connecting block is rotatably connected to one side of each fixed block via a rotating shaft. A protective plate is fixedly connected to one side of each connecting block.

[0005] Preferably, a hollow frame is fixedly connected to the inner cavity of the mounting groove, and a support rod is fixedly connected to the inner cavity of the hollow frame. A limit plate is rotatably connected to the surface of the support rod. Two limit plates are provided, and one side of the limit plate is rotatably connected to one side of the protective plate through a rotating shaft.

[0006] Preferably, both of the two bidirectional threaded rods are fixedly connected to a synchronous pulley, and the surfaces of the two synchronous pulleys are jointly fitted with a synchronous belt.

[0007] Preferably, a support block is fixedly connected to the inner cavity of the mounting groove, a motor is fixedly connected to one side of the support block, and the output shaft of the motor is fixedly connected to one side of the bidirectional threaded rod.

[0008] Preferably, a support plate is fixedly connected to the inner cavity of the mounting groove, and a reinforcing rod is rotatably connected to the inner cavity of the support plate. One side of the reinforcing rod is fixedly connected to one side of a bidirectional threaded rod.

[0009] Preferably, a baffle is provided on one side of the protective plate, and one side of the baffle is movably hinged to one side of the flip door via a hinge.

[0010] Preferably, a long rod is fixedly connected to one side of the mounting plate, and a slider is slidably connected to the surface of the long rod. One side of the slider is fixedly connected to one side of the movable block.

[0011] The advantages of this utility model are: This invention uses a starting motor to drive one of the bidirectional threaded rods to rotate. The rotation of this rod drives a synchronous pulley, which in turn drives a synchronous belt. This belt, in turn, drives the other synchronous pulley and the bidirectional threaded rod to rotate. The rotation of the threaded rod synchronously moves two moving blocks and a fixed block relative to each other. The movement of the fixed block causes the connecting block and the protective plates to rotate together. At this point, the two protective plates rotate relative to each other and are positioned on either side of the flap door. This vertical positioning of the protective plates on either side of the flap door effectively encloses the flap door, providing some protection for workers and goods and preventing falls when passing through. This improves the safety of the flap door and solves the problem that most existing hoisting cage flap doors lack protective structures on both sides, making it difficult to protect workers and goods and resulting in low safety.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0016] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses a flap door for a construction hoist. (Refer to...) Figure 1-5 A flap door for a construction hoist includes a cage 1, a flap door 2 on one side of the cage 1, and a protective mechanism 3 inside the flap door 2. The cage 1 is the core functional component of the hoist during construction. As a closed metal structure, it is the container that directly carries personnel and materials in the construction hoist. The flap door 2 is located on one side of the cage 1 and can be used to block the gap between the cage 1 and the floor, thereby facilitating the subsequent transportation of personnel and goods in the cage 1 to the platform, thus improving ease of use. The protective mechanism 3 is located on the upper part of the flap door 2 and can enclose both sides of the flap door 2 to prevent goods from falling from both sides or causing personal injury, thereby improving the safety of the flap door 2 and protecting workers and goods.

[0017] The protective mechanism 3 includes a mounting groove 301, which is formed on the surface of the flip door 2. A mounting plate 302 is fixedly connected to the inner cavity of the mounting groove 301. A two-way threaded rod 303 is rotatably connected to the inner cavity of the mounting plate 302. Two two-way threaded rods 303 are provided. A movable block 304 is threadedly connected to the surface of the two-way threaded rod 303. Two movable blocks 304 are provided. A fixed block 305 is fixedly connected to one side of the movable block 304. A connecting block 306 is rotatably connected to one side of the fixed block 305 through a rotating shaft. A protective plate 307 is fixedly connected to one side of the connecting block 306. Mounting groove 301 is located on the upper part of the flip door 2 and can be used to install other components inside the protective mechanism 3, thus providing some support for mounting plate 302. Mounting plate 302 is located on one side of bidirectional threaded rod 303 and can be used to support the installation of bidirectional threaded rod 303, while also facilitating the subsequent rotation of bidirectional threaded rod 303. Two bidirectional threaded rods 303 are provided, both located in the inner cavity of mounting groove 301, with one end penetrating one side of mounting plate 302, allowing rotation within the inner cavity of mounting plate 302. This assists in moving moving blocks 304 during subsequent rotation. Two moving blocks 304 are connected to the surface of each bidirectional threaded rod 303. When the bidirectional threaded rod 303 rotates, the two moving blocks 304 will move relative to each other due to the rotation of the bidirectional threaded rod 303, thereby assisting the subsequent protective mechanism 3 in performing its function and simultaneously supporting and fixing blocks 305. Fixing blocks 305 are located on each The upper part of the movable block 304 can be used to support the connecting block 306 and also serve as a connecting component to connect the movable block 304 and the connecting block 306. This allows the movable block 304 to rotate the connecting block 306 when it moves. The connecting block 306 is connected to both sides of the fixed block 305 via a pivot and can support the protective plate 307. When the connecting block 306 rotates with the movable block 304, it can assist in rotating the protective plate 307, thereby driving the protective plate 307 to rotate and stand on both sides of the flip door 2. There are two protective plates 307. When the connecting block 306 rotates, it can rotate together with the protective plate 307, so that the two protective plates 307 rotate and stand on both sides of the flip door 2, enclosing both sides of the flip door 2 and protecting the workers and goods passing through the flip door 2, thereby improving the safety of the flip door 2. The protective mechanism 3 is located inside the flip door 2, which can reduce the space occupied when not in use.

[0018] Reference Figure 2 and Figure 4 A hollow frame 4 is fixedly connected to the inner cavity of the mounting groove 301. A support rod 5 is fixedly connected to the inner cavity of the hollow frame 4. A limit plate 6 is rotatably connected to the surface of the support rod 5. There are two limit plates 6. One side of the limit plate 6 is rotatably connected to one side of the protective plate 307 via a rotating shaft. The hollow frame 4 can be used to support the installation support rod 5 and fix the support rod 5 inside it. The support rod 5 can be used to support the two limit plates 6 and facilitate the subsequent rotation of the limit plates 6. One side of the limit plate 6 is connected to the protective plate 307 via a rotating shaft. When the protective plate 307 rotates with the connecting block 306, the limit plate 6 can be used to assist the rotation of the protective plate 307, so that the protective plate 307 can rotate stably and be perpendicular to the flip door 2 and located on both sides of the flip door 2, thereby enabling the protective plate 307 to realize its function.

[0019] Reference Figure 4 and Figure 5 Two synchronous pulleys 7 are fixedly connected to the surfaces of the two bidirectional threaded rods 303. The surfaces of the two synchronous pulleys 7 are jointly fitted with a synchronous belt 8. Two synchronous pulleys 7 are provided and fixedly installed on the surfaces of the two bidirectional threaded rods 303 respectively. They can be used to assist a subsequent drive source in driving the two bidirectional threaded rods 303 to rotate. The synchronous belt 8 is fitted on the surfaces of the two synchronous pulleys 7 and can be used to assist the synchronous pulleys 7 in realizing their function, thereby realizing the synchronous drive of the two bidirectional threaded rods 303 to achieve the rotation effect.

[0020] Reference Figure 5 A support block 9 is fixedly connected to the inner cavity of the mounting groove 301. A motor 10 is fixedly connected to one side of the support block 9. The output shaft of the motor 10 is fixedly connected to one side of the bidirectional threaded rod 303. The support block 9 is located in the inner cavity of the mounting groove 301 and can be used to support the motor 10 so that the motor 10 can operate stably. The motor 10 can be used as the drive source of the protective mechanism 3. At the same time, it can cooperate with the synchronous pulley 7 and the synchronous belt 8. When its output shaft drives one bidirectional threaded rod 303 to rotate, it can also drive the other bidirectional threaded rod 303 to rotate together, thereby driving the entire protective mechanism 3 to operate.

[0021] Reference Figure 3 A support plate 11 is fixedly connected to the inner cavity of the mounting groove 301. A reinforcing rod 12 is rotatably connected to the inner cavity of the support plate 11. One side of the reinforcing rod 12 is fixedly connected to one side of the bidirectional threaded rod 303. The support plate 11 is located at the other end of the bidirectional threaded rod 303 and can be used to assist the reinforcing rod 12 in supporting the bidirectional threaded rod 303. The reinforcing rod 12 is connected to the other end of the bidirectional threaded rod 303 and can be used to reinforce the support of the mounting plate 302 on the bidirectional threaded rod 303, thereby improving the stability of the bidirectional threaded rod 303 during rotation.

[0022] Reference Figure 1 A baffle 13 is provided on one side of the protective plate 307. One side of the baffle 13 is hinged to one side of the flip door 2. The baffle 13 can be used to cover some components of the protective mechanism 3 to prevent the components located inside the mounting groove 301 from affecting the subsequent use of the flip door 2 when the protective mechanism 3 is in use, thereby facilitating the manual transport of goods.

[0023] Reference Figure 2 A long rod 14 is fixedly connected to one side of the mounting plate 302. A slider 15 is slidably connected to the surface of the long rod 14. One side of the slider 15 is fixedly connected to one side of the moving block 304. The long rod 14 and the slider 15 cooperate with each other to reinforce and stabilize the movement of the moving block 304, thereby further improving the stability of the movement of the moving block 304.

[0024] Working Principle: When using this device, the operator first uses the flip-up door 2 to establish a connection between the cage 1 and the floor. Then, the motor 10 is started. The output shaft of the motor 10 drives one of the bidirectional threaded rods 303 to rotate. The rotation of the bidirectional threaded rod 303 drives the synchronous pulley 7 to rotate, which in turn drives the synchronous belt 8. The synchronous belt 8, in turn, drives the other synchronous pulley 7 and the bidirectional threaded rod 303 to rotate. Simultaneously, the rotation of the bidirectional threaded rod 303 also synchronously drives the relative movement of two moving blocks 304 and a fixed block 305. The movement of the fixed block 305, via a rotating shaft, drives the two connecting blocks... When block 306 rotates relative to the other, the connecting block 306 will simultaneously drive the protective plate 307 to rotate as well. At this time, the two protective plates 307 will rotate relative to each other due to the connecting block 306, and then rotate 90 degrees to be located on both sides of the flip door 2. That is, by rotating the protective plates 307 vertically to be located on both sides of the flip door 2, the two sides of the flip door 2 can be enclosed, providing a certain degree of protection for workers and goods, preventing workers or goods from falling when passing through the flip door 2, thereby improving the safety of the flip door 2. This solves the problem that most existing flip doors 2 of the cage 1 lack protective structures on both sides, making it difficult to protect the passing workers and goods, and resulting in low safety.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
