[0017] 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 protection scope of the present utility model.

[0018] like Figures 1 to 4 As shown, this utility model provides a conveniently replaceable elevator base plate, including multiple side frames 1. Each pair of adjacent side frames 1 shares a common connecting mechanism 2 at one end. Multiple mounting mechanisms 3 are engaged on the upper surfaces of the multiple side frames 1. The connecting mechanism 2 includes a connecting rod 20 located at one end of two adjacent side frames 1. Two limiting brackets 22 are fitted onto the outer side of the connecting rod 20, and fixing bolts 23 are inserted into the outer side of the limiting brackets 22, which are fixedly engaged with the connecting rod 20. Two limiting rods 25 are fixedly installed at one end of each side frame 1, and these limiting rods 25 engage with the limiting brackets 22. When installing the elevator base plate, first place the connecting rod 20 at one end of two adjacent side frames 1. Then, fit the two limiting brackets 22 onto the outer side of the connecting rod 20 and adjust their positions. Finally, insert the two limiting rods 25 fixed at one end of each side frame 1 into the corresponding limiting holes 24 on the limiting brackets 22 to achieve initial positioning. Next, insert the fixing bolt 23 into the outside of the limiting frame 22 and tighten it to fix it in place with the connecting rod 20, thereby firmly connecting the two adjacent side frames 1 together. When it is necessary to disassemble the side frame 1 for replacement or maintenance, simply loosen the fixing bolt 23, remove the limiting frame 22 from the connecting rod 20, and the limiting rod 25 will disengage from the limiting hole 24, thus separating the adjacent side frames 1.

[0019] Specifically, the installation mechanism 3 includes multiple assembly base plates 30, which are located on the upper surfaces of multiple side frames 1. Mounting brackets 31 are engaged on both sides of each assembly base plate 30. Two mounting bolts 34 are inserted into one side of each mounting bracket 31, and the mounting bolts 34 are fixedly connected to one side of the assembly base plate 30. Mounting hooks 38 are inserted into both ends of each mounting bracket 31, and the mounting hooks 38 engage with the upper surfaces of the side frames 1. Multiple positioning bolts 35 are inserted into both ends of each mounting bracket 31. Two positioning holes 36 are opened on one side of each mounting hook 38, and one end of each positioning bolt 35 passes through and engages with the positioning hole 36. After the multiple side frames 1 are installed, the assembly base plates 30 are installed. First, the mounting bracket 31 is engaged with one side of the assembly base plate 30 through its mounting groove 32. Then, the mounting bolts 34 are passed through the mounting bracket 31 and tightened to fix the mounting bracket 31 to the assembly base plate 30. Next, insert the mounting hooks 38 into both ends of the mounting bracket 31, so that the inner side of the hook opening 37 on one side of the mounting hook 38 engages with the upper surface of the side frame 1. Then, insert the positioning bolts 35 into both ends of the mounting bracket 31, with one end passing through the positioning hole 36 on the mounting hook 38, and tighten the positioning bolts 35 to complete the positioning and fixing. In this way, multiple assembly base plates 30 are installed on the upper surface of multiple side frames 1 through the mounting mechanism 3. When it is necessary to replace the assembly base plate 30, loosen the positioning bolts 35 and the mounting bolts 34, remove the mounting hooks 38 and the mounting bracket 31, and the assembly base plate 30 can be disassembled for replacement.

[0020] Furthermore, the multiple limiting holes 24 on the upper surface of the limiting frame 22 can precisely engage with the limiting rod 25 at one end of the side frame 1. This design makes the positioning of adjacent side frames 1 more accurate during connection, effectively avoiding the side frames 1 from shifting or misaligning during the connection process, ensuring the stability and accuracy of the connection mechanism 2, and thus improving the stability of the entire elevator base plate structure.

[0021] Furthermore, the stabilizing rod 27 inserted at the lower end of the connecting rod 20 and the stabilizing pad 26 fixed at the lower end of the stabilizing rod 27 allow the stabilizing pad 26 to contact the ground or other supporting surfaces during elevator operation. This increases the contact area between the connecting mechanism 2 and the supporting surface, disperses the pressure borne by the connecting rod 20, enhances the stability of the connecting mechanism 2, reduces the problem of loosening of the connection caused by elevator operation vibration, and improves the safety of elevator base plate use.

[0022] It is worth noting that the reinforcing frame 21 fixed on one side of the side frame 1 can strengthen the structure of the side frame 1. During elevator operation, the side frame 1 will be subjected to significant pressure and stress. The reinforcing frame 21 can increase the strength and rigidity of the side frame 1, prevent the side frame 1 from deforming or being damaged due to excessive force, extend the service life of the side frame 1, and ensure the reliability of the overall structure of the elevator base plate.

[0023] It is worth noting that the mounting groove 32 on one side of the mounting bracket 31 engages with one side of the assembly base plate 30. This engaging connection makes the installation and disassembly of the mounting bracket 31 and the assembly base plate 30 more convenient and quick. During installation, simply align one side of the assembly base plate 30 with the mounting groove 32 and insert it to complete the initial positioning; during disassembly, simply pull the assembly base plate 30 out of the mounting groove 32, greatly improving the efficiency of installing and replacing the assembly base plate 30.

[0024] It is worth mentioning that the anti-loosening washers 33 fitted on the outside of the mounting bolts 34 and positioning bolts 35 are designed to prevent the bolts from loosening during elevator operation due to frequent vibrations and stress. The anti-loosening washers 33 increase the friction between the bolts and the connecting parts, effectively preventing the mounting bolts 34 and positioning bolts 35 from loosening. This ensures the firmness of the connection between the components of the mounting mechanism 3, avoids instability in the assembly of the base plate 30 caused by loose bolts, and improves the safety of the elevator base plate.

[0025] It is worth emphasizing that the hook opening 37 on one side of the mounting hook 38 engages with the upper surface of the side frame 1. This design allows the mounting hook 38 to be more securely hung on the side frame 1. The shape and size of the hook opening 37 are carefully designed to fit tightly against the upper surface of the side frame 1, increasing the friction and engagement force between the mounting hook 38 and the side frame 1, preventing the mounting hook 38 from falling off during elevator operation, and ensuring the reliability of the mounting mechanism 3.

[0026] Working principle: When installing the elevator base plate, first place the connecting rod 20 at one end of two adjacent side frames 1. Next, fit the two limiting brackets 22 onto the outside of the connecting rod 20 and adjust their positions. Then, insert the two limiting rods 25 fixed at one end of the side frame 1 into the corresponding limiting holes 24 on the limiting brackets 22 to achieve initial positioning. Afterward, insert the fixing bolts 23 into the outside of the limiting brackets 22 and tighten them to fix them in place with the connecting rod 20, thereby firmly connecting the two adjacent side frames 1 together. When it is necessary to disassemble the side frame 1 for replacement or maintenance, simply loosen the fixing bolts 23, remove the limiting brackets 22 from the connecting rod 20, and the limiting rods 25 will disengage from the limiting holes 24, thus separating the adjacent side frames 1.

[0027] After the multiple side frames 1 are installed, the assembly base plate 30 is installed. First, the mounting bracket 31 is engaged with one side of the assembly base plate 30 through the mounting groove 32 on one side. Then, the mounting bolt 34 is passed through the mounting bracket 31 and tightened to fix the mounting bracket 31 to the assembly base plate 30. Next, the mounting hook 38 is inserted into both ends of the mounting bracket 31, so that the inner side of the hook opening 37 on one side of the mounting hook 38 engages with the upper surface of the side frame 1. After that, the positioning bolt 35 is inserted into both ends of the mounting bracket 31, with one end passing through the positioning hole 36 on the mounting hook 38, and the positioning bolt 35 is tightened to complete the positioning and fixing. In this way, multiple assembly base plates 30 are installed on the upper surface of multiple side frames 1 through the mounting mechanism 3. When it is necessary to replace the assembly base plate 30, the positioning bolt 35 and the mounting bolt 34 are loosened, the mounting hook 38 and the mounting bracket 31 are removed, and the assembly base plate 30 can be disassembled for replacement.
