[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Please see Figure 1-3 This utility model provides a technical solution:

[0024] Example 1

[0025] Regarding the aforementioned problem 1: the existing elevator frames are prone to unstable fixing, which can easily lead to frame displacement and affect the overall safety of the elevator.

[0026] The solution is as follows: A multi-level lifting frame includes a device body 1, which includes a bottom frame 2, support beams 3, and a top frame 4. The bottom frame 2 has a rectangular structure. Two sets of support beams 3 are symmetrically installed on the top of the bottom frame 2. The top frame 4 is installed on top of the two sets of support beams 3. The support beams 3 have a rectangular structure, with a through-type structure at the bottom and top. A top limiting block 5 is provided at the top of the support beam 3. The top limiting block 5 has an L-shaped structure, and a first small limiting block 6 and a second small limiting block 6 are provided at the top of the top limiting block 5. Limiting blocks 7, the first small limiting block 6 and the second small limiting block 7 are installed at an angle. The first small limiting block 6 and the second small limiting block 7 are both trapezoidal in shape. During installation, the workers hoist another lifting frame to the top of the top frame 4. Then, the L-shaped top limiting blocks 5 on the four support beams 3 can limit the four corners of the lifting frame to prevent the lifting frame from shifting. Then, the second small limiting blocks 6 and the second small limiting blocks 7 on the top of the top limiting blocks 5 can fit against the four corners of the lifting frame. In this way, a set of lifting frames is fixed together again.

[0027] Bottom support pads 14 are provided at the four corners of the bottom of the bottom frame 2. The bottom support pads 14 are rectangular in shape. The bottom support pads 14 are provided with shock-absorbing mounting sleeves 15 on top. The shock-absorbing mounting sleeves 15 are provided with shock-absorbing blocks 16 on top. The shock-absorbing blocks 16 are cylindrical in shape and made of rubber. The bottom support pads 14 at the bottom of the bottom frame 2 can effectively improve the stability of the bottom frame 2, while the shock-absorbing blocks 16 on top of the shock-absorbing mounting sleeves 15 can effectively dampen the lifting box and prevent the bottom of the lifting box from directly contacting the bottom frame 2. When the lifting box descends to the top of the bottom frame 2, the bottom of the lifting box will directly contact the shock-absorbing blocks 16 on the shock-absorbing mounting sleeves 15. The shock-absorbing blocks 16 are made of rubber, thereby achieving the purpose of buffering and shock absorption, and preventing the bottom of the lifting box from directly contacting the bottom frame 2.

[0028] Example 2

[0029] Regarding the second problem to be solved above: the existing elevator frame structure has low strength, which easily leads to bending after bearing load and stress, affecting the overall safety of the elevator.

[0030] The solution is as follows: A first reinforcing frame 8 is provided between the two sets of support beams 3. The first reinforcing frame 8 has a cross-shaped structure and can connect the support beams 3 to ensure the stability of the entire frame.

[0031] The bottom frame 2 and the top frame 4 are both provided with a second reinforcing frame 9 on their inner sides. The second reinforcing frame 9 has a U-shaped structure and includes a main beam 10 and a connecting beam 11. The main beam 10 has a rectangular structure and the connecting beam 11 has a U-shaped structure. There is a set of connecting beams 11, and the set of connecting beams 11 is respectively installed at the left and right ends of the main beam 10. The second reinforcing frame 9 on the inner sides of the bottom frame 2 and the top frame 4 is for reinforcing the structure of the bottom frame 2 and the top frame 4.

[0032] The top frame 4 has a rear mounting port 12 at its rear end, and a rear reinforcing frame 13 is provided on one side of the rear mounting port 12. The rear reinforcing frame 13 has an L-shaped structure and is used to improve the strength of the rear end of the top frame 4 and improve the overall stability.

[0033] Working principle: During operation, the staff hoists another lifting frame to the top of the top frame 4. Then, the L-shaped top limit blocks 5 on the four support beams 3 can limit the four corners of the lifting frame to prevent the lifting frame from shifting. Then, the second small limit blocks 6 and the second small limit blocks 7 at the top of the top limit blocks 5 can fit into the four corners of the lifting frame. In this way, a set of lifting frames is fixed together again.

[0034] The present invention comprises: 1. Device body; 2. Base frame; 3. Support beam; 4. Top frame; 5. Top limiting block; 6. First small limiting block; 7. Second small limiting block; 8. First reinforcing frame; 9. Second reinforcing frame; 10. Main beam; 11. Connecting beam; 12. Rear mounting port; 13. Rear reinforcing frame; 14. Bottom support pad; 15. Vibration damping mounting sleeve; 16. Vibration damping block. All components are general standard parts or parts known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. The problem solved by this invention is that the frames of existing elevators are easily unstable and prone to displacement, affecting the overall safety of the elevator. This invention, through the combination of the above components, effectively facilitates the installation between elevator frames, resulting in a simple and stable installation method that prevents displacement between elevator frames.
