Description

Technical Field

[0001] This application relates to the field of elevator technology, and in particular to a counterweight structure and an elevator. Background Technology

[0002] The traction system is the core drive and transmission system in an elevator, directly determining the elevator's operating performance, safety, and efficiency.

[0003] In related technologies, the traction machine of the traction device is installed on the support of the load-bearing beam, and a buffer for vibration reduction and noise reduction is installed between the support and the load-bearing beam. However, due to improper arrangement of the support, the buffer may experience uneven stress, resulting in poor vibration reduction and noise reduction effect. Summary of the Invention

[0004] This application provides a traction machine support structure, traction device and elevator, which aims to improve the problem of poor shock absorption and noise reduction effect caused by uneven force on the buffer component.

[0005] The specific technical solution is as follows:

[0006] An embodiment of the first aspect of this application provides a traction machine support structure, disposed on a first load-bearing beam and a second load-bearing beam that are parallel to each other and spaced apart. The traction machine support structure includes: a first support, mounted on the first load-bearing beam, the first support including a base plate, the base plate forming a plurality of mounting holes for connection with the traction machine; a second support, mounted on the second load-bearing beam; a buffer assembly including at least two buffer members spaced between the first load-bearing beam and the first support, and at least one buffer member disposed between the second support and the second load-bearing beam; and a third support, the two ends of the third support being respectively connected to the first support and the second support and overlapping with the buffer members; wherein, the axis of the traction machine forms an acute angle with the extension direction of the first load-bearing beam, and the plurality of mounting holes include a first mounting hole and a second mounting hole penetrating the base plate and the third support, the center connecting line of the first mounting hole and the second mounting hole, the extension direction of the third support, and the axis of the traction machine are parallel to each other.

[0007] In this application, the center connection line of the first and second mounting holes, the extension direction of the third support, and the axis of the traction machine are defined to be parallel to each other. This allows for the creation of a vertical force transmission path from one side of the traction machine to the third support. When the traction machine is installed at an angle, because the center connection line of the first and second mounting holes is parallel to the extension direction of the third support, the connecting bolts in these two mounting holes can directly and vertically transfer the load of the traction machine to the third support. From there, the load is vertically transferred to the buffer components at both ends and the two load-bearing beams, causing the third support to exert a downward vertical pressure on the buffer components at both ends. This improves the uneven force distribution on the two buffer components at both ends of the third support, reduces wear, and thus helps to increase the service life of the buffer components and the effect of vibration reduction and noise reduction, thereby improving the comfort and stability of the elevator operation.

[0008] In some embodiments, the buffer assembly includes a first buffer and a second buffer disposed between the first load-bearing beam and the first support, and a third buffer and a fourth buffer disposed between the second load-bearing beam and the second support, wherein the two ends of the third support overlap with the first buffer and the third buffer, respectively.

[0011] In some embodiments, the traction machine support structure further includes a fourth support, the two ends of which are respectively connected to the first support and the second support;

[0012] One end of the fourth support overlaps with the fourth buffer, and the other end is located between the first buffer and the second buffer.

[0013] In some embodiments, the extension direction of the fourth support is perpendicular to the extension direction of the first load-bearing beam.

[0014] In some embodiments, the buffer assembly includes a first buffer member and a second buffer member disposed between the first load-bearing beam and the first support, and a fifth buffer member disposed between the second load-bearing beam and the second support, wherein the center of the first buffer member, the center of the second buffer member and the center of the fifth buffer member form a triangle.

[0015] The two ends of the third support overlap with the first buffer and the fifth buffer, respectively;

[0016] The traction machine support structure further includes a fourth support, the two ends of which are connected to the first support and the second support, respectively, and the two ends of the fourth support overlap with the second buffer and the fifth buffer, respectively.

[0017] In some embodiments, the plurality of mounting holes further include a third mounting hole and a fourth mounting hole that are symmetrically arranged with respect to the first mounting hole and the second mounting hole about the axis of the traction machine;

[0018] One of the third mounting hole and the fourth mounting hole is opposite to the second buffer.

[0019] In some embodiments, the first support includes a first base plate and a connecting plate connecting the first base plate and the base plate, and the buffer is disposed between the first base plate and the first load-bearing beam;

[0020] The ends of the third and fourth supports are sandwiched between the first base plate and the substrate.

[0021] In some embodiments, the first support further includes a plurality of first support plates disposed between the first base plate and the base plate, the first support plates being connected to the connecting plate and opposite to the buffer member located on the first load-bearing beam.

[0022] In some embodiments, the second support includes a second base plate and a top plate, and the buffer is disposed between the second base plate and the second load-bearing beam;

[0023] The ends of the third and fourth supports are sandwiched between the second bottom plate and the top plate.

[0024] An embodiment of the second aspect of this application provides a traction device, including a traction machine and the traction machine support structure described in the first aspect, wherein the traction machine is mounted on the substrate through the plurality of mounting holes.

[0042] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0043] like Figures 1 to 4 As shown, in a first aspect, this application provides a traction machine support structure 10, which is mounted on a first load-bearing beam 110 and a second load-bearing beam 120 that are parallel to each other and spaced apart. The traction machine support structure 10 includes a first support 210, a second support 220, a buffer assembly 300, and a third support 230. The first support 210 is mounted on the first load-bearing beam 110, and the second support 220 is mounted on the second load-bearing beam 120. The first support 210 includes a base plate 211, which has a plurality of mounting holes 212 for connecting to the traction machine 20. The buffer assembly 300 includes at least two buffer members 301 spaced between the first load-bearing beam 110 and the first support 210, and at least one buffer member 301 spaced between the second support 220 and the second load-bearing beam 120. The two ends of the third support 230 are respectively connected to the first support 210 and the second support 220 and overlap with the buffer members 301. The axis L2 of the traction machine 20 forms an acute angle with the extension direction of the first load-bearing beam 110. The plurality of mounting holes 212 include a first mounting hole 2121 and a second mounting hole 2122 that penetrate the base plate 211 and the third support 230. The center connecting line L1 of the first mounting hole 2121 and the second mounting hole 2122, the extension direction of the third support 230, and the axis L2 of the traction machine 20 are parallel to each other.

[0044] The first load-bearing beam 110 and the second load-bearing beam 120 are arranged parallel to each other and spaced apart. They are load-bearing components located at the top of the hoistway and can transfer all dynamic and static loads of the elevator to the main building structure. The first load-bearing beam 110 and the second load-bearing beam 120 can be, for example, I-beams.

[0045] The first support 210 and the second support 220 are respectively erected on the two main load-bearing beams. The two ends of the third support 230 are connected to the first support 210 and the second support 220 respectively. The third support 230 is a structural longitudinal beam that spans the two main load-bearing beams.

[0046] The buffer assembly 300 includes at least two buffer members 301 spaced apart from the first load-bearing beam 110 and the first support 210. In this way, the at least two buffer members 301 can form at least two buffer support points on the first load-bearing beam 110, and the connecting line between the centers of the at least two buffer members 301 is parallel to the extension direction of the first load-bearing beam 110.

[0047] The buffer assembly 300 also includes at least one buffer member 301 disposed between the second support 220 and the second load-bearing beam 120. Thus, the at least one buffer member 301 can form at least one buffer support point on the second load-bearing beam 120. Therefore, the buffer assembly 300 is configured to reduce vibration and noise in the elevator, improving the comfort of elevator operation.

[0048] The overlap between the two ends of the third support 230 and the buffer 301 refers to, as shown in the reference Figure 1 and Figure 4 Viewed from above (top to bottom), the orthographic projection of one end of the third support 230 overlaps with the orthographic projection of a buffer member 301 on the first load-bearing beam 110, and the orthographic projection of the other end of the third support 230 overlaps with the orthographic projection of a buffer member 301 on the second load-bearing beam 120. In this way, the load on the third support 230 can be directly transferred to the buffer members 301 at both ends.

[0049] The base plate 211 on the first support 210 is provided with multiple mounting holes 212, and the bottom of the traction machine 20 can be directly mounted on the base plate 211 through the multiple mounting holes 212. The axis L2 of the traction machine 20 is the central axis of the traction wheel 21, and the axis L2 forms an acute angle with the extension direction of the first load-bearing beam 110, which is equivalent to installing the traction machine 20 in a deflected state.

[0050] The deflection angle of the traction machine 20 directly determines the tilt angle of the traction sheave. By deflecting the traction machine 20 relative to the first load-bearing beam 110 at a certain angle (usually a few degrees to more than ten degrees), the traction sheave 21 of the traction machine 20 can form a non-perpendicular angle with the car top sheave and the counterweight sheave. This design has the following advantages:

[0051] First, the wrap angle of the traction rope can be increased, thereby improving the friction between the traction rope and the sheave groove, and thus enhancing the traction capacity. Second, by placing the traction sheave 21 at an angle, the relative positions of each sheave can be adjusted, making the layout of the traction machine 20, car top sheave, and counterweight sheave more compact and improving the utilization rate of the hoistway. Furthermore, with the angled placement, the paths of the traction ropes are three-dimensionally intersecting, avoiding interference between multiple ropes and extending the service life of the traction ropes and sheave grooves. Moreover, the angled placement allows for fine-tuning of the suspension angle of the traction ropes, resulting in a more uniform tension distribution among the ropes, reducing car swaying or shaking caused by uneven tension, and improving passenger comfort. In addition, in related technologies, without angled placement, increasing the wrap angle may require additional rewinding devices, while with the traction machine 20 angled, the wrap angle can be increased without adding extra equipment, thus also simplifying the structure.

[0052] However, when the traction machine 20 is placed at an angle, the load direction of the traction machine 20 will change. If the third support 230 is arranged perpendicular to the first load-bearing beam 110, the load of the traction machine 20 will be pressed obliquely onto the third support 230 through the base plate 211. This will cause uneven force on the two buffers 301 opposite to the two ends of the third support 230, resulting in poor shock absorption and noise reduction effect, easy wear, and reduced service life.

[0053] Based on this, in this application, the center connection line L1 of the first mounting hole 2121 and the second mounting hole 2122, the extension direction of the third support 230, and the axis L2 of the traction machine 20 are defined to be parallel to each other. In this way, a vertical force transmission path from one side of the traction machine 20 to the third support 230 can be constructed.

[0054] When the traction machine 20 is installed at an angle, since the center connection line L1 of the first mounting hole 2121 and the second mounting hole 2122 is parallel to the extension direction of the third support 230, the connecting bolts in these two mounting holes can directly and vertically transfer the load of the traction machine 20 to the third support 230, and then vertically transfer it to the buffer components 301 at both ends and the two load-bearing beams through the third support 230, causing the third support 230 to generate a vertical downward pressure on the buffer components 301 at both ends. This improves the uneven force distribution on the two buffer components 301 at both ends of the third support 230, reduces wear, and thus helps to improve the service life of the buffer components 301 and the effect of vibration reduction and noise reduction, thereby improving the comfort and stability of the elevator operation.

[0055] Furthermore, since the center connection line L1 of the first mounting hole 2121 and the second mounting hole 2122 is parallel to the extension direction of the third support 230, it is equivalent to the third support 230 also being arranged at the same angle. This firstly reduces the width of the third support 230 itself, saving space, while also lowering manufacturing costs and reducing weight. Secondly, compared to the arrangement perpendicular to the two load-bearing beams, additional space can be reserved on the side of the third support 230 away from the traction machine 20. This also helps improve the structural compactness of the traction machine support structure 10, thereby improving the utilization rate of the shaft space and the convenience of its arrangement.

[0056] Secondly, since the third support 230 bears vertical pressure, and the third support 230 is connected to both the first support 210 and the second support 220, the cyclic stress and stress concentration phenomena borne by each connecting weld will be improved, which will also help to improve the service life and reliability of the traction machine support structure 10.

[0057] In addition, the aforementioned parallel constraints can provide a geometric reference for on-site installation, enabling the traction machine 20 to be installed with precise offset quickly, which also helps to improve the convenience of installation, commissioning and maintenance.

[0058] like Figure 1 , Figure 4 and Figure 5 As shown, in some embodiments, the buffer assembly 300 includes a first buffer 3011 and a second buffer 3012 disposed between the first load-bearing beam 110 and the first support 210, and a third buffer 3013 and a fourth buffer 3014 disposed between the second load-bearing beam 120 and the second support 220. The two ends of the third support 230 overlap with the first buffer 3011 and the third buffer 3013 respectively. The distance between the center points of the first buffer 3011 and the second buffer 3012 is greater than the distance between the center points of the third buffer 3013 and the fourth buffer 3014.

[0059] The line connecting the center points of the first buffer 3011 and the second buffer 3012 is parallel to the extension direction of the first load-bearing beam 110, and the line connecting the center points of the third buffer 3013 and the fourth buffer 3014 is parallel to the extension direction of the second load-bearing beam 120. The first load-bearing beam 110 and the second load-bearing beam 120 are also parallel to each other. Thus, the center points of the four buffers 301 are connected sequentially to form a trapezoidal structure without right angles.

[0060] The distance between the center points of the first buffer 3011 and the second buffer 3012 is greater than the distance between the center points of the third buffer 3013 and the fourth buffer 3014. That is, of the two parallel sides of the trapezoid, the longer side falls on the first load-bearing beam 110, and the shorter side falls on the second load-bearing beam 120.

[0061] This configuration offers several advantages. First, since the traction machine 20 is mounted on the base plate 211 of the first support 210, which is correspondingly mounted on the first load-bearing beam 110, placing its long side on the first load-bearing beam 110 allows the first support 210 to generate a wider supporting moment, thereby improving the reliability and stability of the support. Second, the trapezoidal shape defines the maximum space occupied by the traction machine support structure 10. The spaces on the opposite sides of the two hypotenuses of the trapezoid are located outside the space occupied by the traction machine support structure 10, allowing space for the arrangement of other components such as cables, traction ropes, speed governors, and rope end assemblies 31. This improves the structural compactness of the traction machine support structure 10, thereby increasing the utilization rate of the shaft space and the convenience of elevator component arrangement. Furthermore, the large reserved space allows for arrangement possibilities under different shaft space conditions, further enhancing the scalability and versatility of the traction machine support structure 10.

[0062] Please refer to Figure 1 and Figure 4 In some embodiments, the traction machine support structure 10 further includes a fourth support 240 disposed on one side of the third support 230. The two ends of the fourth support 240 are respectively connected to the first support 210 and the second support 220, and the two ends of the fourth support 240 overlap with the second buffer 3012 and the fourth buffer 3014, respectively.

[0063] In this embodiment, the fourth support 240 of the traction machine support structure 10 is another longitudinal beam with a span, which together bears the load of the traction machine 20. Its two ends are connected to the first support 210 and the second support 220, and overlap with the remaining two buffer members 301. That is, the third support 230 and the fourth support 240 can be considered as the two hypotenuses of a trapezoid. The first support 210, the third support 230, the second support 220, and the fourth support 240 together form a closed trapezoidal frame.

[0064] This configuration, firstly, helps to further improve the support strength and reliability, thereby enhancing the safety and stability of the traction machine support structure 10. Secondly, the third support 230 and the fourth support 240 can directly define the physical boundaries of the occupied space, with the inner part being the core load-bearing area and the outer part being reserved space. Thus, a virtual trapezoid can be coupled to the solid frame, thereby improving the convenience of the support layout of the traction machine support structure 10.

[0065] like Figures 1 to 4 As shown, in some other embodiments, the traction machine support structure 10 further includes a fourth support 240, the two ends of which are connected to the first support 210 and the second support 220 respectively. One end of the fourth support 240 overlaps with the fourth buffer 3014, and the other end is located between the first buffer 3011 and the second buffer 3012.

[0066] This embodiment proposes an alternative arrangement of the fourth support 240 within the trapezoidal structure of four buffer members 301. One end of the fourth support 240 still overlaps with the fourth buffer member 3014, while the other end is connected to the first support 210 plate-beam structure between the first buffer member 3011 and the second buffer member 3012. In this way, the fourth support 240 is actually located inside the trapezoidal boundary.

[0067] With this configuration, firstly, the fourth support 240 can still share the load of the traction machine 20, thereby improving support strength and reliability, and consequently enhancing the safety and stability of the traction machine support structure 10. Secondly, the fourth support 240 can further reduce the space occupied by the traction machine support structure 10. On one hand, this helps to further improve the structural compactness of the traction machine support structure 10. On the other hand, the traction sheave 21 of the traction machine 20 needs to be wound with the traction rope, referring to... Figure 2 The vertical projection of the traction sheave 21 (i.e., the height direction of the shaft) is a rectangle, and the two opposite short sides of the rectangle are the two side flanges of the traction sheave 21. The spatial position of the fourth support 240 can be changed by adjusting its installation position on the first support 210. This ensures that the two side flanges of the traction sheave 21 do not interfere with the fourth support 240. That is, one side flange of the traction sheave 21 is located between the third support 230 and the fourth support 240, and the other side flange is located on the side of the fourth support 240 opposite to the third support 230. This avoids interference at the rope attachment point, thereby improving the convenience and smoothness of the traction rope arrangement, simplifying the structure, and also improving the versatility and adaptability of the traction machine support structure 10.

[0068] Preferably, such as Figures 1 to 4 As shown, the extension direction of the fourth support 240 is perpendicular to the extension direction of the first load-bearing beam 110. This arrangement not only improves the structural compactness of the traction machine support structure 10, but also, once the four support points are determined, the installation position of the fourth support 240 is simultaneously confirmed, thus improving the convenience of arranging the supports of the traction machine support structure 10. Furthermore, the space distribution between the fourth support 240 and the third support 230, as well as the space on the side of the fourth support 240 away from the third support 230, can be balanced, thereby improving space utilization while avoiding rope interference.

[0069] like Figure 6 As shown, in some other embodiments, the buffer assembly 300 includes a first buffer 3011 and a second buffer 3012 disposed between the first load-bearing beam 110 and the first support 210, and a fifth buffer 3015 disposed between the second load-bearing beam 120 and the second support 220. The center of the first buffer 3011, the center of the second buffer 3012 and the center of the fifth buffer 3015 form a triangle. The two ends of the third support 230 overlap with the first buffer 3011 and the fifth buffer 3015 respectively. The traction machine support structure 10 also includes a fourth support 240. The two ends of the fourth support 240 are connected to the first support 210 and the second support 220 respectively, and the two ends of the fourth support 240 overlap with the second buffer 3012 and the fifth buffer 3015 respectively.

[0070] This embodiment proposes another structure for the traction machine support structure 10. The buffer assembly 300 forms three buffer support points: two buffer members 301 are spaced apart between the first load-bearing beam 110 and the first support 210, and one buffer member 301 is located between the second load-bearing beam 120 and the second support 220. The centers of the three buffer members 301 connect to form a triangle, which defines the boundary of the maximum space occupied by the traction machine support structure 10. Firstly, compared to a trapezoidal shape, the triangular shape further improves the structural compactness of the traction machine support structure 10, thereby facilitating the utilization of the hoistway space and the convenience of elevator component arrangement. Furthermore, the increased reserved space also improves the scalability and versatility of the traction machine support structure 10.

[0071] Secondly, the first support 210, the third support 230, the second support 220, and the fourth support 240 together form a closed triangular frame, which is conducive to further improving the support strength and reliability, and thus to improving the safety and stability of the traction machine support structure 10.

[0072] Thirdly, the virtual triangle can be coupled to the physical object, which also helps to improve the convenience of the layout of each support of the traction machine support structure 10.

[0073] Fourthly, by rationally allocating the angles of the triangle, it can be ensured that one side of the traction sheave 21 is located between the third support 230 and the fourth support 240, while the other side is located on the side of the fourth support 240 away from the third support 230. This avoids interference at the rope attachment point, thereby improving the convenience and smoothness of the traction rope arrangement, and also enhancing the versatility and adaptability of the traction machine support structure 10.

[0074] like Figure 3As shown, in some embodiments, the plurality of mounting holes 212 further include a third mounting hole 2123 and a fourth mounting hole 2124 that are symmetrically arranged with respect to the first mounting hole 2121 and the second mounting hole 2122 about the axis L2 of the traction machine 20, and one of the third mounting hole 2123 and the fourth mounting hole 2124 is opposite to the second buffer 3012.

[0075] This embodiment presents a specific structure for multiple mounting holes 212. The bottom of the traction machine 20 is fixedly connected to the base plate 211 through four mounting holes 212. On one side of the axis L2 of the traction machine 20, the load is directly and vertically transmitted to the third support 230 through the first mounting hole 2121 and the second mounting hole 2122, and then vertically transmitted to the first buffer 3011 and the third buffer 3013 at both ends, achieving vertical and non-skewed load transmission. On the other side of the axis L2 of the traction machine 20, one of the third mounting hole 2123 and the fourth mounting hole 2124 is opposite to the second buffer 3012. In this way, most of the load can still be directly and vertically transmitted to the second buffer 3012 through the mounting hole opposite to the second buffer 3012. Thus, a reasonable configuration of the load on the traction machine 20 can be achieved, reducing skewed loads, which is conducive to further improving the uniformity of force on each buffer 301, and further improving the service life of the buffer assembly 300 and the effect of vibration reduction and noise reduction.

[0076] Understandably, due to the reduction in skew load, the requirements for each support of the traction machine support structure 10 can be appropriately reduced, and the strength requirements can be decreased. Therefore, this also helps to reduce the cost of the traction machine support structure 10.

[0077] like Figure 4 As shown, in some embodiments, the first support 210 includes a first base plate 213 and a connecting plate 214 connecting the first base plate 213 and the base plate 211, the buffer 301 is disposed between the first base plate 213 and the first load-bearing beam 110, and the ends of the third support 230 and the fourth support 240 are sandwiched between the first base plate 213 and the base plate 211.

[0078] This embodiment further proposes the specific structure of the first support 210. The first support 210 is I-shaped. The first base plate 213 of the first support 210 is used to press multiple buffers 301. The connecting plate 214 is used to transfer load. The recess of the I-shape can be used to connect the third support 230 and the fourth support 240.

[0079] This arrangement, firstly, facilitates the connection between the third support 230 and the fourth support 240 and the first support 210, as well as improves the structural compactness after the three are connected. Secondly, it improves the structural stiffness and reliability of the first support 210, thereby enhancing the reliability and stability of the support.

[0080] like Figure 4 As shown, in some embodiments, the first support 210 further includes a plurality of first support plates 215 disposed between the first base plate 213 and the base plate 211. The first support plates 215 are connected to the connecting plate 214 and are opposite to the buffer member 301 located on the first load-bearing beam 110.

[0081] The first support plate 215 can be considered as a vertically placed structural reinforcing rib, which can improve the support strength. Furthermore, the first support plate 215 is opposite to the buffer member 301 located on the first load-bearing beam 110. In this way, the load transmitted from the base plate 211 can act on the buffer member 301 through a vertical path. Therefore, on the one hand, the force-bearing area of ​​the buffer member 301 can be increased, avoiding localized indentation or deformation caused by localized high pressure, thereby improving the support reliability and stability of the buffer member 301 on the first load-bearing beam 110. On the other hand, the first support plate 215 can form a new point of application for the buffer member 301, thereby further improving the uniformity of force distribution on the buffer member 301 on the first load-bearing beam 110, which in turn helps to further improve the service life of the buffer assembly 300 and the vibration reduction and noise reduction effect.

[0082] Optionally, a plurality of first support plates 215 may be disposed above the first buffer 3011 and / or above the second buffer 3012.

[0083] like Figure 4 As shown, in some embodiments, the second support 220 includes a second base plate 221 and a top plate 222, a buffer member 301 is disposed between the second base plate 221 and the second load-bearing beam 120, and the ends of the third support 230 and the fourth support 240 are sandwiched between the second base plate 221 and the top plate 222.

[0084] This embodiment presents a specific structure for the second support 220. The second base plate 221 is also used to press against the buffer member 301, and the second base plate 221 can be at the same height as the first base plate 213. Thus, the third support 230 and the fourth support 240 are also at the same height after placement. The top plate 222 is used to connect the tops of the third support 230 and the fourth support 240, connecting their tops together. This arrangement helps to further improve the support strength and rigidity of the traction machine support structure 10, thereby improving the reliability and service life of the traction machine support structure 10.

[0085] Secondly, this application provides a traction device 1, including a traction machine 20 and the traction machine support structure 10 described in the first aspect. The traction machine 20 is mounted on a substrate 211 through a plurality of mounting holes 212.

[0086] The traction device 1 in this embodiment is based on the same inventive concept as the traction machine support structure 10 in the above embodiment. Therefore, the traction device 1 can obtain all the beneficial effects of the traction machine support structure 10 in the corresponding embodiment.

[0087] Thirdly, embodiments of this application provide an elevator including the traction device 1 described in the second aspect.

[0088] The elevator in this embodiment is based on the same inventive concept as the traction device 1 and traction machine support structure 10 in the above embodiments. Therefore, the elevator can obtain all the beneficial effects of the traction machine support structure 10 in the corresponding embodiment.

[0089] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
