[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 protection scope of the present utility model.

[0017] Please see Figures 1-4 As shown, this utility model is a ladder-assisted rapid lifting device, including a floor component 1. Braking components 2 are installed at the inner ends of both sides of the top slot of the floor component 1, and locking components 4 are fixedly installed at both ends of the bottom and top of the floor component 1. A storage lifting ladder component 3 is installed at the end of both braking components 2, and the storage lifting ladder component 3 is correspondingly arranged in the top slot of the floor component 1. The staircase assembly 3 includes a staircase hinge 301. Several stair treads 302 are installed between the staircase hinges 301. The outer walls of the top stair treads 302 are fixedly installed on the inner walls of one end of the staircase opening 104 by positioning posts 303. The bottom stair treads 302 are fixedly installed with extension rods 304 at both ends. Limiting spring blocks 305 are fixedly installed on the outer sides of the ends of the extension rods 304 on both sides.

[0018] By installing a storage lift assembly 3 on the device, the inconvenience of going up and down using a traditional straight ladder can be avoided, ensuring high work efficiency and improving safety.

[0019] Floor assembly 1 includes a low floor slab 101, and a high floor slab 103 is fixedly installed on the top of the low floor slab 101 by a support column 102. A stair opening 104 is provided in the middle of one side of the high floor slab 103. The floor assembly 1 provides basic installation support. The low floor slab 101 supports the high floor slab 103 by the support column 102. The stair opening 104 in the high floor slab 103 provides installation and lifting space for housing the elevator assembly 3.

[0020] The braking assembly 2 includes a folding hinge 201. One end of the folding hinge 201 is fixedly installed on the inner walls of both sides of the stairwell 104, and the other end of the folding hinge 201 is limited by a pneumatic support rod 202. The end of the pneumatic support rod 202 is fixedly installed with a limiting hinge 203. The braking assembly 2 is used to assist in the lifting and limiting of the storage elevator assembly 3. The folding hinge 201 of the braking assembly 2 is fixed on the inner walls of both sides of the stairwell 104, and the pneumatic support rod 202 connected to its end can provide assistance through extension and retraction.

[0021] The outer walls of the two ends of the stair-specific hinge 301 are limited and installed on the inner walls of the two side limit hinges 203. The limit hinge 203 at the end of the pneumatic support rod 202 is associated with the stair-specific hinge 301 of the elevator assembly 3. This not only limits the range of motion of the stair-specific hinge 301, but also works with the pneumatic support rod 202 to achieve smooth lifting and lowering of the elevator assembly 3. The stair-specific hinge 301 of the elevator assembly 3 is connected to several stair treads 302. The top stair tread 302 is fixed to the inner walls of both ends of the stair opening 104 by the positioning post 303 as the lifting and lowering fixed endpoint. The extension support rod 304 and the limit spring block 305 at the end of the bottom stair tread 302 can cooperate with the locking component 4 to achieve fixation.

[0022] The locking component 4 includes a positioning groove block 401, which is fixedly installed on both sides of the top of the lower floor slab 101. A sliding groove 402 is provided on the top of the positioning groove block 401, and a limit lock 403 is provided on the outer wall of one end of the sliding groove 402.

[0023] The limiting latch 403 is adapted to the limiting spring block 305. The positioning groove block 401 of the locking component 4 is fixed on both sides of the top of the lower floor slab 101. The sliding groove 402 at the top can accommodate the sliding of the extension rod 304. The limiting latch 403 at the end is adapted to the limiting spring block 305, thus realizing the rapid lifting and stable storage of the device.

[0024] The ladder-assisted rapid lifting device provides basic installation support through the floor assembly 1. The lower floor slab 101 supports the upper floor slab 103 through the support column 102. The stairwell 104 opened in the upper floor slab 103 provides installation and lifting space for the ladder assembly 3. The lifting and limiting control of the ladder assembly 3 is achieved by the braking assembly 2. The folding hinge 201 of the braking assembly 2 is fixed to the inner walls on both sides of the stairwell 104. The pneumatic support rod 202 connected to its end can provide assistance through extension and retraction. The limiting hinge 203 at the end of the pneumatic support rod 202 is associated with the stair-specific hinge 301 of the ladder assembly 3, which can limit the range of motion of the stair-specific hinge 301. The device can be enclosed and, in conjunction with the pneumatic support rod 202, achieve smooth lifting and lowering of the elevator assembly 3. The stair-specific hinge 301 for storing the elevator assembly 3 connects several stair treads 302. The top stair tread 302 is fixed to the inner walls of both ends of the stair opening 104 by positioning posts 303 as lifting and fixing endpoints. The extension support rod 304 of the bottom stair tread 302 and the limiting spring block 305 at the end can cooperate with the locking assembly 4 to achieve fixation. The positioning groove block 401 of the locking assembly 4 is fixed on both sides of the top of the lower floor slab 101. The sliding groove 402 at the top can accommodate the sliding of the extension support rod 304. The limiting lock 403 at the end is adapted to the limiting spring block 305, ultimately realizing the device. Rapid lifting and stable storage; In the initial state, the storage elevator component 3 is folded and stored in the area corresponding to the top slot of the stairwell 104 of the floor component 1. The pneumatic support rod 202 of the braking component 2 is in the retracted state, and the limit spring block 305 is not engaged with the limit lock 403 of the locking component 4. When unfolding, the operator triggers the extension function of the pneumatic support rod 202. After the pneumatic support rod 202 extends, it drives the stair-specific hinge 301 to move through the limit hinge 203, pushing the stair tread 302 to unfold downward with the positioning post 303 as the fixed end point. During the descent, the stair tread 302 gradually unfolds through the stair-specific hinge 301, and the extension support rod 304 slides along the sliding groove 402. When sliding down to the usable height, the limiting spring block 305 engages with the limiting lock buckle 403 to lock and fix it, allowing people to climb and use it. When storing, the operator releases the engagement between the limiting spring block 305 and the limiting lock buckle 403, triggering the retraction function of the pneumatic support rod 202. After the pneumatic support rod 202 retracts, it pulls the stair-specific hinge 301 through the limiting hinge 203, causing the stair step 302 to fold upward with the positioning post 303 as the fixed end point. The extension rod 304 slides upward along the sliding groove 402, and the storage elevator assembly 3 gradually retracts into the top slot of the floor assembly 1. When the pneumatic support rod 202 retracts to its shortest state, the device returns to the initial storage state, completing the entire workflow.
