[0002] Home elevators are elevators installed in private residences for the exclusive use of a single family member. As people's living standards continue to improve, home elevators are becoming increasingly popular. However, due to the lack of pre-designed elevator shafts in residential buildings, the usable shaft space is relatively small. Additionally, the pit is located below the lowest floor served by the elevator car within the shaft.

[0003] Existing elevator shaft pits require the installation of numerous pieces of equipment, including traction steel belt guide wheel devices and traction steel belt end fixing devices. However, these devices are typically installed individually in the pit, resulting in a cluttered structure, cumbersome installation, and inconvenient maintenance. Therefore, a corresponding technical solution needs to be designed to address these issues. Summary of the Invention

[0025] The base body 10 includes a bottom crossbeam 11, which is a channel steel.

[0026] The traction steel belt end fixing device 20 includes a first bracket and a fixing shaft 21. The first bracket includes two first side plates 22. The two first side plates 22 are arranged opposite to each other and are respectively fixed to the two sides of the bottom crossbeam 11. The fixing shaft 21 is installed between the two first side plates 22.

[0027] The traction steel belt guide wheel device 30 includes a second bracket and a guide wheel 31. The second bracket includes two second side plates 32, which are arranged opposite to each other and fixed to the two sides of the bottom crossbeam 11 respectively. The guide wheel 31 is installed between the two second side plates 32.

[0028] The above-mentioned solution simplifies installation and facilitates future maintenance by installing a base body 10 and mounting the traction steel belt end fixing device 20 and the traction steel belt guide wheel device 30 on it. The traction steel belt guide wheel device 30 guides the movement of the traction steel belt, while the traction steel belt end fixing device 20 secures the end of the traction steel belt. Furthermore, the use of a fixed shaft 21 to fix the end of the traction steel belt reduces the required depth of the shaft pit, thus meeting the design requirements of home elevators.

[0031] In another specific embodiment, such as Figure 1 As shown, the traction steel belt guide wheel device 30 also includes four second rope guide rods 33. The four second rope guide rods 33 are located on the periphery of the guide wheel 31, and the two ends of each second rope guide rod 33 pass through two second side plates 32 and are fixed to the second side plates 32.

[0032] By adopting the above solution: This utility model, by setting a second rope stop 33, can prevent the traction steel belt from jumping and ensure the stable operation of the elevator.

[0033] In another specific embodiment, such as Figure 1 and Figure 2 As shown, the second side plate 32 is provided with a strip-shaped mounting hole 34 through which the second rope guide rod 33 passes, and the length direction of the strip-shaped mounting hole 34 is consistent with the radial direction of the guide wheel 31.

[0034] The above solution is adopted: This utility model uses a strip-shaped mounting hole 34 to finely adjust the installation position of the second rope guide 33.

[0035] In another specific embodiment, such as Figure 1 As shown, there are two traction steel belt guide wheel devices 30, and the traction steel belt end fixing device 20 and the two traction steel belt guide wheel devices 30 are arranged side by side along the length direction of the bottom crossbeam 11.

[0036] In another specific embodiment, such as Figure 1 As shown, the base body 10 also includes two end plates 12, which are fixed to the two ends of the bottom crossbeam 11 respectively.

[0037] In another specific embodiment, such as Figure 1 As shown, the slot of the bottom crossbeam 11 is set facing upwards.
