[0028] DETAILED DESCRIPTION

[0029] The utility model will be described in detail below in combination with specific embodiments. The following embodiments will help the person skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those skilled in the art, without departing from the concept of the utility model, a number of changes and improvements can be made. These all belong to the protection scope of the utility model.

[0030] The utility model provides a guide wheel seat mounting structure, as shown in Figures 1-3 The guide wheel assembly 43 is installed on the guide wheel mounting frame 47.

[0031] The guide wheel mounting frame 47 has a first side beam 490 and a second side beam 491;One end of the guide wheel assembly 43 is inserted into the first side beam 490, and a mounting hole 46 is formed in the second side beam 491, and the diameter of the mounting hole 46 is greater than the maximum diameter of the guide wheel assembly 43;The other end of the guide wheel assembly 43 is detachably mounted on the second side beam 491 through the guide wheel seat 44.

[0032] The guide wheel assembly 43 includes a guide wheel 431, a bearing and a guide wheel shaft 433;The guide wheel 431 is installed on the guide wheel shaft 433 through the bearing;The diameter of the mounting hole 46 is slightly larger than the diameter of the guide wheel 431;

[0033] 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 protruding structure 441 and a flat part structure 442;The size of the protruding structure 441 is smaller than the size of the flat part structure 442. The diameter of the protruding structure 441 matches the diameter of the mounting hole 46 on the second side beam 491;That is, the small outer circle of the boss structure cooperates with the mounting hole 46 of the main seat and protrudes inwardly into the mounting hole 46, and the inner hole of the guide wheel seat cooperates with the guide wheel shaft 433;The guide wheel seat 44 and the second side beam 491 are detachably connected;Specifically, the guide wheel seat 44 and the second side beam 491 are provided with bolt holes for mutual locking, that is, the guide wheel seat 44 and the second side beam 491 are detachably connected through bolts.

[0034] The guide wheel seat mounting structure further includes a guide wheel shaft stop plate 434, which is detachably installed on the guide wheel seat 44, and the end of the guide wheel shaft 433 close to the second side beam 491 is provided with a notch;The inner side of the guide wheel shaft stop plate 434 is clamped into the notch. By abutting the notch and the guide wheel shaft stop plate 434, the rotation of the guide wheel shaft is prevented.

[0035] In a preferred example, such as Figure 2 As shown, the protruding structure 441 and the planar structure 442 are integrally formed. In another preferred embodiment, as... Figure 3 As shown, the protruding structure 441 and the planar structure 442 are not integrally formed structures; the guide wheel seat 44 is composed of a steel plate 435 and a bushing 436 with a smaller outer diameter. The protruding structure 441 is the bushing 436, and the planar structure 442 is the steel plate 435. The bushing 436 and the steel plate 435 are connected by welding or bolt fastening, which can reduce costs.

[0036] In this invention, when installing and replacing the guide wheel, all components can be inserted from the outside of the second side beam 491, and the main base can be designed to form a more stable structure through welding. In addition, this invention features mounting holes and a guide wheel seat, allowing the guide wheel assembly to be inserted into the guide wheel mounting bracket from the side for installation. During disassembly, it can also be pulled out from the side of the guide wheel mounting bracket without disassembling the entire bracket, making the disassembly of the guide wheel assembly more convenient.

[0037] This utility model also provides an elevator that adopts the aforementioned guide wheel seat mounting structure; the guide wheel mounting bracket 47 is the main unit base 700.

[0038] In a preferred embodiment, refer to Figure 1 The main unit 700 is in a straight line shape.

[0039] In another preferred example, such as Figures 4-6 As shown, the main unit 700 includes a high part 702, a connecting part 703 and a recess 704. The height of the high part 702 is higher than that of the recess 704. The two ends of the connecting part 703 are respectively connected to the high part 702 and the recess 704.

[0040] The elevator host 701 is installed on the top surface of the recess 704. The width of the host base 700 is smaller than the width of the elevator host 701. The bottom surface of the recess 704 is the lowest plane in the top structure of the shaft that coincides with the projection plane of the car.

[0041] like Figure 5 , Figure 6As shown, the car top 713 of the elevator has a car top cross beam 705, a first side beam 706, a second side beam 707 and a decorative plate 710, the plane where the upper surface of the beams is defined as the upper plane 708, and the plane where the lower surface of the beams is defined as the lower plane 709. The car top cross beam 705 is located in the middle 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 car top 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 mounting space 712; the decorative plate 710 covers the electrical device mounting space 712. The bottom area of the recess 704 is smaller than the area of the first space 711.

[0042] As shown in the drawings, Figure 7 When the elevator car runs upward to the limit position, the lower plane of the main seat recess 704 protrudes into the upper plane of the elevator car top, specifically, the recess 704 protrudes into the first space 711 and can infinitely approach the lower plane 709.

[0043] The matching relationship between the conventional main seat and the elevator car top is that when the elevator car runs upward to the limit position, the lowest plane in the shaft top structure body that coincides with the car projection plane is misaligned in height with the upper plane 708 of the car top, that is, the height of the bottom surface of the existing main seat is always higher than the height of the upper plane 708 of the car top.

[0044] Unlike the conventional main seat, the bottom surface of the main seat recess 704 of the utility model can protrude into the upper plane of the elevator car top, so when the elevator car runs upward to the limit position, the lowest surface height of the main seat in the utility model is lower than the height of the upper plane 708 of the car top, so the design can reduce the minimum top height requirement of the elevator. In addition, the width of the shaft top structure body sinking into the lower plane of the elevator car top + the width of the two side beams of the car top is the limit minimum width of the car. And the width of the main seat recess 704 is smaller than the width of the main seat, so the main seat can achieve the minimum limit width of the car.

[0045] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0046] The specific embodiments of the present application are described above. It needs to be understood that the present application is not limited to the specific embodiments described above, and various changes or modifications can be made by those skilled in the art within the scope of the claims, which does not affect the essential content of the present application. In the case of no conflict, the embodiments of the present application and the features in the embodiments can be combined with each other arbitrarily.
