The following embodiment will help the person skilled in the art further understand the utility model, but does not limit the utility model in any form. It should be pointed out that, for ordinary skilled in the art, without departing from the utility model concept, can also make a number of changes and improvements. These all belong to the protection scope of the utility model.

[0025] The utility model provides a kind of structure for reducing elevator top layer height, as shown in Figure 1As shown, it comprises a host 40, a host seat 41 and a roof structure 42; the roof structure 42 is provided with a recessed part 421 and a planar part 422; the host 40 is installed at the bottom end of the host seat 41; the bottom height of the host 40 is lower than the bottom height of the host seat 41; the length and width of the host 40 are both smaller than the length and width of the recessed part 421; the downward convex projection of the host 40 relative to the host seat 41 is located in the downward recessed recessed part 421 of the roof.

[0026] When the elevator car runs upward to the limit position, the bottom of the host 40 is embedded in the recessed part 421 provided on the roof structure 42, and the height of the bottom of the host 40 is lower than the height of the planar part 422 provided on the roof structure 42. At this time, the height of the bottom of the host 40 is higher than or equal to the height of the top surface of the recessed part 421.

[0027] In the utility model, the host and the host seat can be combined as a host assembly, forming a larger horizontal reference plane and a horizontal convex plane formed by part of the downward protruding components; the roof is designed as a larger horizontal reference plane and a downward recessed recessed plane; the horizontal downward convex projection plane of the host assembly is located in the downward recessed recessed plane of the roof; when the car moves upward to the top, the horizontal convex plane of the host assembly enters the downward recessed recessed plane of the roof, thereby reducing the requirement for the space of the top floor of the elevator.

[0028] As shown in the drawings, Figure 5 , Figure 6 In a preferred example, it comprises a roof cross beam 705, a first side beam 706, a second side beam 707 and a decorative plate 710, and the plane where the upper surface of the beam is located is defined as an upper plane 708, and the plane where the lower surface of the beam is located is defined as a lower plane 709. The roof cross beam 705 is located in the middle part of the first side beam 706 and the second side beam 707 and connects the first side beam 706 and the second side beam 707. The roof cross beam 705 divides the space between the first side beam 706 and the second side beam 707 into a first space 711 and an electrical device installation space 712; the decorative plate 710 covers the electrical device installation space 712. In this preferred example, the recessed part 421 is the enclosed part of the roof cross beam 705, the inner side wall of the first side beam 706, the inner side wall of the second side beam 707 and the lower plane 709, and the planar part 422 is the top surface part of the decorative plate 710.

[0029] In a preferred example, the host seat 41 is a character-shaped host seat 41. As shown in the drawings, Figures 2-4As shown, the main seat 41 is used to install the main machine 40 and the guide wheel assembly 43. The guide wheel assembly 43 is installed on the main seat side beam 45 through the guide wheel seat 44; the guide wheel assembly 43 includes a guide wheel 431, a bearing, and a guide wheel shaft 433 with a notch; the guide wheel 431 is installed on the guide wheel shaft 433 with the notch through the bearing.

[0030] The main seat side beam 45 is provided with an installation hole 46 slightly larger than the diameter of the guide wheel 431;

[0031] The guide wheel seat 44 is a boss structure with an inner hole, and the diameter of the inner hole matches the diameter of the guide wheel shaft 433. The boss structure includes a convex structure 441 and a flat part structure 442, and the size of the convex structure 441 is smaller than the size of the flat part structure 442. The diameter of the convex structure 441 matches the diameter of the installation hole 46 on the main seat side beam 45, that is, the small outer circle of the boss structure is matched with and protrudes inwardly into the installation hole 46, and the inner hole of the guide wheel seat is matched with the guide wheel shaft 433; the guide wheel seat 44 and the main seat side beam 45 are provided with locking installation holes for mutual locking, that is, the guide wheel seat 44 and the main seat side beam 45 can be detachably connected.

[0032] The main seat 41 further includes a guide wheel shaft stop plate 434 which is detachably installed on the guide wheel seat 44 and whose one side surface is clamped into the guide wheel shaft notch, specifically, the inner side surface of the guide wheel shaft stop plate 434 is clamped into the guide wheel shaft notch.

[0033] As shown in the drawings, Figure 3 In one preferred embodiment, the convex structure 441 and the flat part structure 442 are integrally formed, and in another preferred embodiment, as shown in the drawings, Figure 4 In one preferred embodiment, the convex structure 441 and the flat part structure 442 are integrally formed, and in another preferred embodiment, as shown in the drawings,

[0034] In the conventional guide wheel assembly, the guide wheel shaft is installed in cooperation with the main seat side beam 45, and the installation hole 46 on the main seat side beam 45 is smaller than the outer diameter of the guide wheel; therefore, when the guide wheel of the installed and running elevator is replaced, the car and the counterweight need to be lifted, the main seat side beam 45 needs to be disassembled after the main seat is disassembled, and then the guide wheel can be replaced. In the guide wheel seat 44 in the utility model, all components can be placed from the outside of the main seat side beam 45 during installation and replacement of the guide wheel, so that the main seat does not need to be disassembled, and the main seat can be designed to be a more stable structure.
