[0014] (III) Beneficial Effects

[0015] This utility model provides an opening and closing device for the cage door of a construction hoist, which has the following beneficial effects:

[0016] 1. This opening and closing device for the cage door of a construction hoist, through the arrangement of a lifting component and a rolling component, operates by starting a drive motor to rotate a threaded rod. The threaded rod rotates within the connecting block, causing the cage door body to slide and rise within the door frame, thus opening and closing the cage door body. Simultaneously, as the cage door body slides within the door frame, its surface presses against the roller surface, causing the roller to rotate on the sliding rod surface. This pressure forces the sliding rod to compress the support spring, and the positioning rod slides to maintain stability, thereby achieving stable opening and closing of the cage door body and preventing swaying during opening and closing. Furthermore, by replacing sliding friction with rolling friction, friction is significantly reduced, thus minimizing equipment wear.

[0017] 2. The opening and closing device for the cage door of the construction hoist, through the setting of buffer components and protective frames, allows for the movement and collision of goods when personnel transport them into the cage body. Due to the shaking of the hoist during operation, the goods may move and collide. When the goods collide with the protective frame, the protective frame transmits pressure to the damping hydraulic rod, causing the damping hydraulic rod to contract under force, and the buffer spring to deform under force and generate elastic force, thereby achieving the effect of buffering and shock absorption of the collision, avoiding damage to the cage door body caused by the collision, and improving the service life of the opening and closing device for the cage door of the construction hoist.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figures 1 to 4This utility model provides a technical solution: an opening and closing device for a construction hoist cage door, comprising two sets of cage door bodies 1. A door frame 2 is slidably connected to the surface of the cage door body 1. A positioning block 3 is fixedly connected to one side of the top of the door frame 2. A lifting assembly 4 is rotatably connected inside the positioning block 3. Through the arrangement of the lifting assembly 4 and the rolling assembly 5, the opening and closing of the cage door body 1 is stabilized, preventing the cage door body 1 from shaking during opening and closing. At the same time, rolling friction replaces sliding friction, thereby significantly reducing friction and reducing equipment wear. Several sets of rolling assemblies 5 are slidably connected inside the door frame 2. Four sets of buffer assemblies 6 are fixedly connected in a rectangular array on one side of the cage door body 1. Through the arrangement of the buffer assemblies 6 and the protective frame 7, the effect of shock absorption and vibration reduction for collisions is achieved, avoiding damage to the cage during collisions. The door body 1 was damaged, which improved the service life of the opening and closing device used for the cage door of the construction hoist. One end of the buffer assembly 6 is fixedly connected to the protective frame 7. The lifting assembly 4 includes a threaded rod 401 rotatably connected to the inside of the positioning block 3. The top of the threaded rod 401 is fixedly connected to the drive motor 402, and the bottom of the threaded rod 401 is threadedly connected to the connecting block 403. The rolling assembly 5 includes a sliding rod 501 slidably connected to the inside of the door frame 2. The surface of the sliding rod 501 is rotatably connected to the roller 502. Both ends of the sliding rod 501 are fixedly connected to the support spring 503. The inside of the support spring 503 is fitted with the positioning rod 504. The buffer assembly 6 includes a damping hydraulic rod 601 fixedly connected to one side of the cage door body 1 in a rectangular array. The surface of the damping hydraulic rod 601 is fitted with the buffer spring 602.

[0026] Two sets of crossbars 8 are fixedly connected to the inner side of the door frame 2. Several sets of sliding grooves that are compatible with the sliding rod 501 are opened on the inner wall of the door frame 2. The sliding grooves enable the sliding rod 501 to slide.

[0027] The surface of the connecting block 403 is provided with a threaded hole that matches the threaded rod 401. The connecting block 403 is fixedly connected to one side of the top of the cage door body 1. The threaded hole serves to drive the connecting block 403 to rise and fall.

[0028] A cage body 9 is fixedly connected to one side of the door frame 2. Two sets of slide rails 10 are provided on one side of the cage body 9. The slide rails 10 facilitate the sliding of the cage body 9.

[0029] Two sets of support rods 11 are fixedly connected to one side of the door frame 2. A gasket 12 is fixedly connected to the bottom of the support rod 11. The gasket 12 is fixedly connected to the top of the cage body 9. The setting of the gasket 12 increases the support surface.

[0030] Four sets of lifting rings 13 are fixedly connected to the top of the main body 9 of the cage. An escape window 14 is provided on the top of the main body 9 of the cage, which serves to facilitate opening in case of equipment failure.

[0031] The protective frame 7 has several sets of railings 15 fixedly connected inside. The surface of the drive motor 402 is fitted with a motor housing 16, which is fixedly connected to the top surface of the positioning block 3. The motor housing 16 serves to protect the drive motor 402.

[0032] In this invention, the working steps of the device are as follows:

[0033] First step: When in use, start the drive motor 402 to drive the threaded rod 401 to rotate, and then the threaded rod 401 rotates in the connecting block 403, and drives the cage door body 1 to slide and rise inside the door frame 2, thereby opening and closing the cage door body 1.

[0034] Second step: Simultaneously, when the cage door body 1 slides inside the door frame 2, the cage door body 1 presses against the surface of the roller 502, causing the roller 502 to rotate on the surface of the sliding rod 501. The pressing force causes the sliding rod 501 to push the support spring 503 to contract under force, and the positioning rod 504 slides to maintain stability.

[0035] The third step: When in use, personnel transport goods into the main body 9 of the hoist. Due to the shaking caused by the operation of the hoist, the goods may move and collide. When the goods collide with the protective frame 7, the protective frame 7 transmits pressure to the damping hydraulic rod 601, causing the damping hydraulic rod 601 to contract under force, and the buffer spring 602 to deform under force and generate elastic force.
