[0021] As attached Figure 1 The figure shown is an adjustable steel belt guide wheel lower beam assembly of this utility model, including a lower beam welding assembly 1, a steel belt wheel assembly 2, a wheel axle fixing component 3, a first adjusting bolt assembly 4, and a second adjusting bolt assembly 5. (See attached figure) Figure 2 As shown, the lower beam welding assembly 1 includes inner crossbeams 11 arranged in parallel opposite directions. An outer crossbeam 12, parallel to the inner crossbeam 11, is located on the outer side of the inner crossbeam 11. Longitudinal beams 13 are connected to both ends of the inner crossbeams 11 and 12. The inner crossbeams 11, 12, and 13 are welded together to form a stable frame. The inner crossbeam 11 includes a base plate 111 and side plates 112 perpendicular to both sides of the base plate 111. A first through hole 113 is opened on the base plate 111, and several first mounting holes are arranged around the first through hole 113. An auxiliary plate 14, perpendicularly connected to the base plate 111 and side plates 112 respectively, is welded to one side of the first through hole 113 and the first mounting holes. The base plate 111, side plates 112, longitudinal beams 13, and auxiliary plates 14 enclose a chamber 15. A wheel axle fixing member 3 is installed inside the chamber 15, as shown in the attached diagram. Figure 3 Appendix Figure 4As shown, the wheel axle fixing component 3 includes a mounting plate 33 that fits against the base plate 111 and a first adjusting plate 31 and a second adjusting plate 32 that are perpendicular to the mounting plate 33. The first adjusting plate 31 is parallel to the side plate 112, and the second adjusting plate 32 is parallel to the auxiliary plate 14. The two ends of the steel belt pulley assembly 2 pass through the first through hole 113 of the base plate 111 and are connected to the mounting plate 33 of the wheel axle fixing component 3. The first adjusting plate 31 and the side plate 112 have corresponding first adjusting holes. The first adjusting bolt assembly 4 passes through the first adjusting holes to connect the first adjusting plate 31 and the side plate 112. The second adjusting plate 32 and the auxiliary plate 14 have corresponding second adjusting holes. The second adjusting bolt assembly 5 passes through the second adjusting holes to connect the second adjusting plate 32 and the auxiliary plate 14. A number of inserts 6 are placed between the first adjusting plate 31 and the side plate 112, and between the second adjusting plate 32 and the auxiliary plate 14. The first adjusting bolt assembly 4 adjusts the steel pulley assembly 2 vertically, and the second adjusting bolt assembly 5 adjusts the steel pulley assembly 2 horizontally. The inserts 6 are inserted into the screws of the first adjusting bolt assembly 4 and the second adjusting bolt assembly 5. The number of inserts 6 can be adjusted according to the thickness requirements. By increasing or decreasing the number of inserts 6, the relative position of the wheel axle fixing part 3 and the lower beam welding assembly 1 can be ensured, and their changes during elevator operation can be avoided.

[0022] As attached Figure 3 As shown, a welding nut 7 is welded onto the first adjusting plate 31, and an adjusting screw 8 is screwed into the welding nut 7. The tail of the adjusting screw 8 abuts against the side plate 112. Similarly, the second adjusting plate 32 also has a welding nut 7 and an adjusting screw 8 screwed into it. The tail of the adjusting screw 8 abuts against the auxiliary plate 14. Rotating the adjusting screw 8 makes it easier to adjust the position of the steel pulley assembly 2.

[0023] The mounting plate 33 of the wheel axle fixing component 3 has a second through hole 34 corresponding to the first through hole 113 and a second mounting hole 35 corresponding to the first mounting hole. The inner side of the mounting plate 33 has a wheel axle clamping plate 9, which is bolted to the end of the steel belt pulley assembly 2 along with the mounting plate 33 and the base plate 111.

[0024] The steel pulley assembly 2 includes a connecting shaft and pulleys mounted at both ends of the connecting shaft, and the longitudinal beam 13 has notches 131 corresponding to the pulleys.

[0025] The lower beam welding assembly 1 includes a reinforcing beam 10 that connects the two inner crossbeams 11, making the overall structure more stable.

[0026] This utility model features an adjustable steel belt guide wheel lower beam assembly with a split design. The entire assembly is shipped from the factory, ensuring installation accuracy while allowing for some adjustment space for each component. After on-site installation, if the steel belt deviates due to load or other factors, the steel belt wheel assembly 2 can be adjusted horizontally or vertically by adjusting the first adjusting bolt assembly 4 or the second adjusting bolt assembly 5. The adjustment is simple, and the position of the steel belt wheel assembly 2 can be fixed after adjustment, greatly improving adjustment efficiency. This utility model is simple and reliable to operate. Due to the limited space at the top and bottom of household elevators, the installation space is small. If deviation occurs during installation, the subsequent adjustment of the entire lower beam or upper beam will be labor-intensive and difficult. This utility model provides adjustment margin, and the horizontal and vertical alignment of the steel belt wheel can be effectively controlled by turning the wrench to adjust the bolt length. The operation is simple and effective.

[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
