[0040] As Figures 1-5As shown, the elevator comprises a guide rail frame 3, a rack 4 and a cage 5, the rack 4 is arranged on the guide rail frame 3 along a first direction, and an elevator driving device can drive the cage 5 to move relative to the guide rail frame 3 along the first direction. In this embodiment, the elevator driving device comprises a driving mechanism 1 and a guide mechanism 2. The driving mechanism 1 comprises a mounting frame 11 and a driving assembly 12, the mounting frame 11 is fixedly connected with the cage 5, the driving assembly 12 is mounted on the mounting frame 11, and the output end of the driving assembly 12 is connected with a driving gear 122 engaged with the rack 4, for driving the cage 5 to move relative to the guide rail frame 3 along the first direction, and the guide mechanism 2 comprises a first guide assembly (not shown in the figure) and a second guide assembly (not shown in the figure) arranged at intervals on the mounting frame 11, the first guide assembly comprises a plurality of first guide wheels 21 axially parallel to each other, the second guide assembly comprises a plurality of second guide wheels 22 axially parallel to each other, the plurality of first guide wheels 21 are axially perpendicular to the plurality of second guide wheels 22, and the plurality of first guide wheels 21 and the plurality of second guide wheels 22 are both axially perpendicular to the first direction, and the plurality of first guide wheels 21 and the plurality of second guide wheels 22 are both in rolling abutment with the guide rail frame 3 to limit the movement of the cage 5 along the first direction. It can be understood that by arranging the elevator driving device, the plurality of first guide wheels 21 are axially perpendicular to the plurality of second guide wheels 22, and the plurality of first guide wheels 21 and the plurality of second guide wheels 22 are both axially perpendicular to the first direction, and the plurality of first guide wheels 21 and the plurality of second guide wheels 22 jointly act on the guide rail frame 3 in different directions to guide the movement of the driving mechanism 1, improve the guiding effect of the guide mechanism 2 on the driving mechanism 1 during operation, and further improve the stability of the elevator driving device during operation. The elevator driving device can run smoothly, and the cage 5 runs stably, avoiding the situation that the cage 5 runs stably due to the deviation of the load center of gravity of the cage 5.
[0041] Exemplarily, the guide rail frame 3 is composed of a plurality of guide rail standard sections (not shown in the figure), which facilitates transportation and adjustment of the height (i.e. the length in the first direction) of the guide rail frame 3, and a plurality of guide rails (not shown in the figure) matched with the plurality of first guide wheels 21 and the plurality of second guide wheels 22 can be directly formed on the guide rail frame 3, which facilitates the cooperation between the guide mechanism 2 and the guide rail frame 3, and saves labor.
[0042] Further, as Figures 3-5As shown, in the second direction, multiple first guide wheels 21 are located at both ends of the guide rail frame 3; in the third direction, multiple second guide wheels 22 are located at the end of the guide rail frame 3 away from the cage 5. It can be understood that the multiple first guide wheels 21 cooperate with the guide rail frame 3 to clamp the guide rail frame 3 in the second direction, further improving the guiding effect of the first guide wheels 21 on the drive mechanism 1.

The backrest wheel 9 is spaced apart from the drive gear 122. When the drive gear 122 meshes with the rack 4, the backrest wheel 9 rolls against the side of the rack 4 away from the drive gear 122, so that the drive gear 122 and the backrest wheel 9 clamp the rack 4, thereby improving the stability of the meshing between the drive gear 122 and the rack 4.
[0045] Further, the driving assembly 12 further comprises a reversing element (not shown in the figure) and a driving element 121, the output end of the driving element 121 and the driving gear 122 are connected through the reversing element, and the axial direction of the driving gear 122 is perpendicular to the length direction of the driving element 121. It can be understood that by arranging the reversing element, the movement direction of the output end of the driving element 121 can be changed, so that the axial direction of the driving gear 122 is perpendicular to the length direction of the driving element 121, which facilitates arranging the driving gear 122 on the side of the mounting frame 11 close to the rack 4, i.e. the side of the mounting frame 11 away from the cage 5, reduces the probability of human intervention in the rotation of the driving gear 122, and the driving gear 122 runs stably, and at the same time facilitates arranging the driving element 121 along its length direction on the mounting frame 11, reduces the space occupied by the driving mechanism 1 to the cage 5. Exemplarily, the reversing element can be a gear reversing element or other types of reversing elements, which are all prior art, and will not be described herein.
[0046] In the embodiment, as shown in Figure 2 In order to improve the service life of the driving mechanism 1 and the stability of the driving mechanism 1, a plurality of driving assemblies 12 are arranged in the first direction, which cooperate with the rack 4 to avoid too much load on a single driving assembly 12, which is beneficial to improve the service life of the driving mechanism 1, and even if one of the driving assemblies 12 is damaged, the other driving assemblies 12 can still work normally, and the overall stability of the driving mechanism 1 is high.

[0048] Further, as shown in Figure 2As shown, the driving mechanism 1 further comprises a mounting plate 13, the driving assembly 12 is mounted on the mounting plate 13, and the mounting plate 13 is detachably connected with the mounting frame 11. It can be understood that by arranging the mounting plate 13 which is detachably connected with the mounting frame 11, the driving assembly 12 can be first mounted on the mounting plate 13 during actual installation, and then the driving assembly 12 is mounted on the mounting frame 11 through the mounting plate 13. The mounting plate 13 is convenient to arrange the accommodating groove, through hole and other structures matched with the driving assembly 12, so as to improve the stability of the driving assembly 12.

In addition, the safety hooks 6 can also alleviate the influence of external force on the driving device for elevator, and ensure the safe operation of the driving device for elevator.
[0051] Further, as shown in Figures 2-3 , the mounting frame 11 is provided with a protective cover 8. It can be understood that by arranging the protective cover 8, the driving assembly 12 can be protected, and the rain, dust and other external factors can be prevented from entering the inside of the driving assembly 12, so as to avoid the damage or performance decline of the driving assembly 12.
