[0033] The embodiments of the present application are further described below in combination with the drawings.

[0034] Reference is made to Figure 1、 2 As shown, the traction machine rack comprises a bearing assembly 100, a support assembly 200 and a bracket assembly 300, the bearing assembly 100 comprises two bases 110, a first bearing beam 120, a second bearing beam 130 and an intermediate beam 140, the two bases 110 are arranged in parallel, the two ends of the first bearing beam 120 are connected to the parallel ends of the two bases 110 respectively, the two ends of the second bearing beam 130 are connected to the other parallel ends of the two bases 110 respectively, the first bearing beam 120 and the second bearing beam 130 are arranged in parallel, and the two ends of the intermediate beam 140 are connected to the two sides opposite to the ends close to one of the bases 110 of the first bearing beam 120 and the second bearing beam 130 respectively; the support assembly 200 comprises a first support beam 210 and a second support beam 220, the two ends of the first support beam 210 are connected to the sides away from the bases 110 of the first bearing beam 120 and the intermediate beam 140 respectively; the two ends of the second support beam 220 are connected to the sides away from the bases 110 of the first bearing beam 120 and the second bearing beam 130 respectively; the two ends of the bracket assembly 300 are connected to the side away from the intermediate beam 140 of the first support beam 210 and the side away from the first bearing beam 120 of the second support beam 220 respectively, and the two ends of the bracket assembly 300 are located above the connection between the first support beam 210 and the intermediate beam 140 and above the second support beam 220 respectively, and the position of the side surface of the bracket assembly 300 away from the intermediate beam 140 and close to the second support beam 220 is provided with a traction machine mounting position (not marked in the figure).

[0035] The one end of the bracket assembly 300 of the traction machine in the above embodiment is connected to the first bearing beam 120 and the intermediate beam 140 through the first support beam 210, the other end is connected to the first bearing beam 120 and the second bearing beam 130 through the second support beam 220, and the two ends of the bracket assembly 300 are located above the connection between the first support beam 210 and the intermediate beam 140 and above the second support beam 220 respectively, so that the bracket assembly 300 is inclined on the parallel first bearing beam 120 and the second bearing beam 130, thereby making the traction machine mounting position form a reasonable inclination angle, optimizing the traction direction of the traction steel wire rope, making the center of the car and the counterweight on a straight line, thereby reducing the influence of the eccentric moment on the stability of the elevator operation.

[0036] It can be understood that, with reference to Figure 1 、 2As shown, the traction machine frame also includes a guide wheel assembly 400, which is connected to the support assembly 300 on the side away from the traction machine mounting position and located beside the intermediate beam 140. By positioning the guide wheel assembly 400 on the side of the support assembly 300 away from the traction machine mounting position and beside the intermediate beam 140, the running trajectory of the traction rope is effectively optimized, reducing the swaying of the traction wire rope, improving traction efficiency, reducing the lateral load on the guide rail, and reducing wear. In some embodiments, the guide wheel assembly 400 and the support assembly 300 can be connected by using bolts and nuts for a fixed connection.

[0037] Understandably, referring to Figure 1 , 2 As shown, the traction machine frame also includes a first rope head assembly 500, a second rope head assembly 520, and a rope head bracket 530. The first rope head assembly 500 is disposed at one end of the second load-bearing beam 130 near the intermediate beam 140. The two ends of the rope head bracket 530 are respectively connected to the side of the first load-bearing beam 120 away from the base 110 and the side of the second load-bearing beam 130 away from the base 110, and are located beside the second support beam 220. The second rope head assembly 520 is disposed on the rope head bracket 530. By fixing the first rope head assembly 500 to one end of the second load-bearing beam 130 near the intermediate beam 140, and by connecting the two ends of the rope head bracket 530 to the sides of the first and second load-bearing beams 130 away from the base 110 and located beside the second support beam 220, and by fixing the second rope head assembly 520 on the rope head bracket 530, the rope head is subjected to balanced force, reducing rope head sway and uneven wire rope tension, and further improving the smoothness and comfort of elevator operation.

[0038] Understandably, referring to Figure 1 , 2 As shown in Figure 3, the support assembly 200 further includes a first damping assembly 230, a second damping assembly 240, a third damping assembly 250, and a fourth damping assembly 260. The first damping assembly 230, the second damping assembly 240, the third damping assembly 250, and the fourth damping assembly 260 are respectively disposed at the connection points of the first support beam 210 and the first load-bearing beam 120, the first support beam 210 and the intermediate beam 140, the second support beam 220 and the first load-bearing beam 120, and the second support beam 220 and the second load-bearing beam 130. By setting up a multi-point damping structure, the vibration and impact transmission of the frame are effectively reduced, thereby reducing noise and resonance during elevator operation. In some embodiments, the first damping assembly 230, the second damping assembly 240, the third damping assembly 250, and the fourth damping assembly 260 can all be selected as springs 501, hydraulic or pneumatic dampers, or rubber elements, etc.

[0039] Understandably, referring to Figure 1 , 2As shown, the support assembly 200 further comprises three anti-rollover supports 270, one end of each of the three anti-rollover supports 270 is connected to two ends of the second support beam 220 close to the side of the first support beam 210 and the end of the first support beam 210 close to the second support beam 220, and the other end of each of the three anti-rollover supports 270 is connected to the side of the first support beam 210 close to the second support beam 220, the side of the second support beam 130 close to the second support beam 220 and the side of the first support beam 120 close to the first support beam 210. By arranging three anti-rollover supports 270, the anti-rollover ability of the first support beam 210 and the second support beam 220 is enhanced, and the stability of the whole rack is improved.

[0040] As shown in Figure 1 , 2 , one end of each of the three anti-rollover supports 270 is closely attached to the first support beam 210 and the second support beam 220, and each of the three anti-rollover supports is arranged in an L-shaped structure. The L-shaped structure makes the anti-rollover support 270 more stable, saves space, is easy to install and maintain, and has better anti-seismic performance.

[0041] As shown in Figure 1 , 2 , the load-bearing assembly 100 further comprises four protective covers 150, each of which is arranged at the two ends of the first support beam 120 and the second support beam 130. By arranging the protective cover 150 at the two ends of the first support beam 120 and the second support beam 130, the probability of damage to the first support beam 120 and the second support beam 130 when they are hit by external objects is reduced, effectively protecting the first support beam 120 and the second support beam 130.

[0042] In some embodiments, the material of the protective cover 150 can be a flexible material such as polyurethane, rubber or silicone, which can effectively adapt to changes in different mechanical structures, reduce external impact force, and effectively protect the first support beam 120 and the second support beam 130. The protective cover 150 of flexible material can also be adjusted in shape flexibly to meet the installation requirements of the two ends of the support beam of different structures. The protective cover 150 can also use air bag or air cushion technology to set up inflatable protective covers at the two ends of the first support beam 120 and the second support beam 130, which can also effectively absorb the impact force generated by the impact of external objects.

[0043] As shown in Figure 1 , 2As shown, a baffle (not shown) is provided on the side of the guide wheel assembly 400 near the intermediate beam 140. The baffle is used to isolate the guide wheel assembly 400 from the intermediate beam 140. The baffle can prevent the guide wheel assembly 400 from directly contacting the intermediate beam 140, reduce wear caused by friction or collision, and extend the service life of the guide wheel and the intermediate beam 140. In some embodiments, the baffle can be detachably mounted on the guide wheel assembly 400, or it can be integrally formed with the guide wheel assembly 400.

[0044] Understandably, referring to Figure 1 , 2 As shown, a spring 501 is provided at one end of the first rope end assembly 500, and one end of the spring 501 is connected to the side of the second load-bearing beam 130 away from the base 110. The spring 501 can absorb and mitigate the fluctuation of the force on the rope end, avoiding damage to the rope end and the load-bearing beam caused by load changes or the impact force generated when the elevator starts and stops, thus extending the service life of the rope end and the load-bearing beam and indirectly improving the smoothness of elevator operation. The structure of the second rope end assembly 520 is similar to that of the first rope end assembly 500. For specific implementation details of the second rope end assembly 520, please refer to the relevant content in the implementation details of the first rope end assembly 500, which will not be repeated here.

[0045] In some embodiments, a buffer pad made of rubber or polyurethane material may be provided at the connection between the first rope head assembly 500 and the first load-bearing beam 120, which can effectively absorb vibration and impact force and reduce vibration during elevator operation.

[0046] Understandably, referring to Figure 1 , 2 As shown in Figure 3, the first damping assembly 230 includes a first connecting plate 231, a damping pad 232, and a second connecting plate 233. The first side of the first connecting plate 231 is connected to the side of the first support beam 210 away from the bracket assembly 300. The first side of the damping pad 232 is connected to the second side of the first connecting plate 231. The first side of the second connecting plate 233 is connected to the second side of the damping pad 232. The second side of the second connecting plate 233 is connected to the side of the first load-bearing beam 120 away from the base 110. By using the combination of the first connecting plate 231, the damping pad 232, and the second connecting plate 233 in the first damping assembly 230, vibrations and impacts generated during operation are effectively absorbed and mitigated. The elastic properties of the damping pad 232 enable it to reduce the transmission of mechanical vibrations to the structure, reducing vibrations generated during elevator start-up, stopping, or operation, thus improving the elevator's stability and comfort.

[0047] For example, such as Figure 1 , 2As shown in FIGS. 3, the connection mode of the first connecting plate 231 and the first support beam 210 can be fixed by bolts and nuts. The connection mode of the second connecting plate 233 and the first load-bearing beam 120 can be fixed by bolts and nuts. The second connecting plate 233 is fixed and connected to the first load-bearing beam 120 by two groups of bolts and nuts, and has higher stability. In some embodiments, the second connecting plate 233 is provided with a pressure guide plate below, and the second connecting plate 233 is fixed and connected to the pressure guide plate by bolts and nuts. The second connecting plate 233 and the pressure guide plate clamp the first load-bearing beam 120 together, so that the connection between the second connecting plate 233 and the first load-bearing beam 120 is more stable, and the damping effect is improved. The structures of the second damping assembly 240, the third damping assembly 250, and the fourth damping assembly 260 are similar to those of the first damping assembly 230. For specific implementation modes of the structures of the second damping assembly 240, the third damping assembly 250, and the fourth damping assembly 260, reference can be made to the related contents in the implementation modes of the first damping assembly 230, which will not be repeated here.

[0048] The elevator of the second aspect embodiment of the present application comprises the traction machine frame of the first aspect embodiment of the present application, and the stability of the elevator operation can be improved.

[0049] The embodiments of the present application are described in detail above in combination with the drawings, but the present application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art in the technical field, various changes can be made without departing from the purpose of the present application.
