Description

Technical Field

[0001] This utility model belongs to the technical field of machine room-less elevators, and in particular relates to a traction machine base and an elevator. Background Technology

[0002] The traction machine base is the core load-bearing and installation component of a machine-room-less elevator. It is mainly used to fix the traction machine and provide an installation reference for the counterweight rope head, etc.

[0003] Currently, in the field of machine-room-less elevators, traditional traction machine bases are typically fixed to the top or side wall of the shaft using expansion bolts. While this achieves basic installation, its structural design has significant flaws, restricting the effective utilization of shaft space. Specifically, on the one hand, the traction machine base usually only has a single counterweight rope head plate, resulting in an excessively thick counterweight sheave, which excessively occupies shaft space horizontally, limiting the effective arrangement space of the car. On the other hand, because the traction machine base needs to support the large traction machine, to avoid positional interference between the traction machine base and the car's upper beam, the car's upper beam can only move up to below the traction machine base, resulting in wasted space in the vertical direction of the shaft. These two space-occupying problems together make the existing traction machine base structure unsuitable for the actual use needs of small shafts and heavy-duty elevators. Utility Model Content

[0004] In view of this, it is necessary to provide a traction machine base and elevator to meet the needs of small shaft elevators with large load capacity by improving the utilization rate of shaft space.

[0005] A traction machine base, the traction machine base comprising: The base assembly is for mounting on top of the counterweight guide rail; The upper base assembly is located above the lower base assembly and connected to the lower base assembly via a shim block. The upper base assembly extends outward in its width direction relative to the lower base assembly and is used to support the traction machine. At least two counterweight rope head plates are disposed on both sides of the shim block along the length of the base lower assembly and are respectively connected to the base lower assembly.

[0006] Understandably, by employing a raised design and extending the base assembly (which extends in the width of the base component) to support the traction machine, upward space is provided for the car's upper beam, allowing it to rise to the position of the base component. This significantly increases the car's top-floor travel and solves the problem of wasted space in the vertical direction at the top of the hoistway. Simultaneously, by installing at least two counterweight rope head plates, fixing points are provided for the counterweight ropes on multiple counterweight sheaves. This reduces the overall thickness required for counterweight sheave installation and decreases the horizontal space occupied in the hoistway. Therefore, the space utilization rate of the hoistway in both the vertical and horizontal directions is improved, allowing this traction machine base to well adapt to the needs of small hoistways and heavy-duty elevators.

[0007] In one embodiment, the base assembly has multiple fixing points, each of which is used to fix the traction machine. In the width direction of the lower component of the base, the portion of the upper component of the base that extends out relative to the lower component of the base is defined as an extension, and at least one of the fixed points is provided on the extension.

[0008] In one embodiment, the traction machine base further includes a support rib, the support rib having a first connecting portion and a second connecting portion; The first connecting part is located below the extension and abuts against and limits the extension; the second connecting part is used to fix it to the shaft wall.

[0009] Understandably, by providing support ribs below the extension of the components on the base, reliable rigid support is provided. This design effectively prevents the extension from overturning or deforming under load, thereby ensuring the overall stability of the traction machine base structure.

[0010] In one embodiment, the first connecting portion is provided with a clearance groove for avoiding the upper beam of the car.

[0011] It is understandable that the extension is supported by the first connecting part that avoids the upper beam of the car. This arrangement, while ensuring that it does not interfere with the normal upward path of the upper beam of the car, can significantly enhance the support stability of the extension, thereby effectively improving the overall anti-overturning ability and structural reliability of the components on the base.

[0012] In one embodiment, the number of counterweight headplates is configured to be two.

[0013] In one embodiment, the base assembly includes a first plate, a second plate, and a shock-absorbing pad, wherein the shock-absorbing pad is disposed between the first plate and the second plate, and simultaneously abuts against and limits the position of the first plate and the second plate; The first plate is connected to the shim block; the second plate is used to support the traction machine.

[0014] Understandably, the shock-absorbing pads in the base components can absorb and buffer the vibrations generated during the operation of the traction machine, preventing the vibrations from being directly transmitted in the traction machine base, thus improving the stability of the traction machine base installation in the shaft.

[0015] This application also provides an elevator, including a counterweight guide rail, a traction machine, and the aforementioned traction machine base; The lower base assembly is mounted on the top of the counterweight guide rail; the traction machine is mounted on the upper base assembly, and at least one fixed point between the traction machine and the upper base assembly is located on the outer side of the lower base assembly in its width direction.

[0016] In one embodiment, the elevator further includes a counterweight frame slidably mounted on the counterweight guide rail; The counterweight frame is rotatably mounted with at least two counterweight rollers, each of which corresponds to at least two counterweight rope head plates. Each counterweight roller is connected to the traction machine and the corresponding counterweight rope head plate via a counterweight rope.

[0017] In one embodiment, the counterweight frame includes a straight beam and an upper beam, the end of which is disposed inside the straight beam and connected to the straight beam; At least two of the counterweight wheels are rotatably mounted on the upper beam.

[0018] Understandably, by installing the upper beam inside the straight beam, the installation of the upper beam on the straight beam will not occupy space in the thickness direction of the counterweight frame, which helps to achieve a thinner counterweight frame structure, thereby further improving the space utilization rate of the elevator shaft in the horizontal direction.

[0019] In one embodiment, the upper beam is connected to the straight beam by fasteners; The counterweight wheel is rotatably mounted on the upper beam via a counterweight wheel axle; and, in the thickness direction of the counterweight frame, the counterweight wheel axle is located inside the fastener.

[0020] Understandably, by ensuring the counterweight axle does not protrude beyond the fasteners along the thickness of the counterweight frame, this design avoids the counterweight axle occupying extra space in the thickness direction of the counterweight frame. This helps to minimize the overall thickness of the counterweight frame, resulting in a more compact structural design.

[0021] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: The traction machine base and elevator claimed in this application utilize a raised design with an upper component extending from the base's lower component in the width direction to support the traction machine. This design provides upward space for the car's upper beam, allowing it to rise to the location of the lower component, thus significantly increasing the car's top-floor travel and resolving the issue of wasted space in the vertical direction at the top of the hoistway. Simultaneously, by providing at least two counterweight rope head plates, fixing points are provided for the counterweight ropes on multiple counterweight sheaves, reducing the overall thickness required for counterweight sheave installation and minimizing the horizontal space occupied in the hoistway. This improves the utilization rate of the hoistway's space in both the vertical and horizontal directions, enabling the traction machine base to effectively adapt to the needs of small hoistways and heavy-duty elevators.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] like Figures 4 to 6 As shown, the traction machine base 100 claimed in this application is used in an elevator (not shown) to support the traction machine 200. Here, the elevator is specifically a machine-room-less elevator.

[0036] like Figures 1 to 6As shown, the traction machine base 100 provided in this application includes a lower base assembly 10, an upper base assembly 20, and at least two counterweight rope head plates 30. The lower base assembly 10 is used to install on the top of the counterweight guide rail 300. The upper base assembly 20 is located above the lower base assembly 10 and is connected to the lower base assembly 10 through a shim block 40. The upper base assembly 20 extends outward relative to the lower base assembly 10 along its width direction X to support the traction machine 200. At least two counterweight rope head plates 30 are disposed on both sides of the shim block 40 in the length direction Y of the lower base assembly 10 and are respectively connected to the lower base assembly 10.

[0037] As can be seen from the above, the traction machine base 100 of this application supports the traction machine 200 by adopting a raised design and extending the base upper component 20 from the base lower component 10 in the width direction X. This provides upward space for the car upper beam 500, allowing it to rise to the position of the base lower component 10, thereby significantly increasing the top-level travel of the car (not shown) and solving the problem of wasted space in the vertical direction of the top floor of the hoistway. At the same time, by setting at least two counterweight rope head plates 30, fixing points are provided for the counterweight ropes on at least two counterweight pulleys 401, which reduces the overall thickness required for the installation of the counterweight pulleys 401 and reduces the space occupied in the horizontal direction of the hoistway. This improves the space utilization rate of the hoistway in both the vertical and horizontal directions, enabling the traction machine base 100 to well adapt to the usage requirements of small hoistways and heavy-duty elevators.

[0038] like Figure 1 , Figure 2 As shown, in one embodiment, the lower base assembly 10 includes a lower base beam 11 and two guide rail sleeves 12. The two guide rail sleeves 12 are respectively fitted onto two counterweight guide rails 300 and fixed to the corresponding counterweight guide rails 300 with connectors. The lower base beam 11 is disposed on the two guide rail sleeves 12 and connected to the two guide rail sleeves 12 respectively, thereby realizing the assembly and fixation of the lower base assembly 10 on the two counterweight guide rails 300.

[0039] Here, the shim block 40 is placed between the lower beam 11 of the base and the upper component 20 of the base and is connected to both respectively, so as to suspend the upper component 20 of the base and realize the double-layer arrangement of the traction machine base 100.

[0040] like Figure 1 , Figure 3As shown, in one embodiment, the upper base assembly 20 is provided with a plurality of fixing points 201, each fixing point 201 being used to fix the traction machine 200; and, in the width direction X of the lower base assembly 10, the portion of the upper base assembly 20 extending relative to the lower base assembly 10 is defined as an extension 210, and at least one fixing point 201 is provided on the extension 210. That is, in this embodiment, the upper base assembly 20 uses the extension 210 extending relative to the lower base assembly 10 in its width direction X to support part of the traction machine 200, so that the lower base assembly 10 has sufficient area to support the traction machine 200, in order to meet the installation requirements of the large-volume traction machine 200 on the upper base assembly 20.

[0041] Here, the extension 210 has two fixed points 201, and the traction machine 200 as a whole has four fixed points 201 formed on the base assembly 20, with the four fixed points 201 arranged symmetrically in pairs.

[0042] like Figure 1 , Figure 2 As shown, in one embodiment, the base assembly 20 includes a first plate 21, a second plate 22, and a shock-absorbing pad 23. The shock-absorbing pad 23 is disposed between the first plate 21 and the second plate 22, and simultaneously abuts against and limits the first plate 21 and the second plate 22, so that the base assembly 20 can use the shock-absorbing pad 23 to absorb and buffer the vibration generated when the traction machine 200 is working, and avoid the vibration from being directly transmitted in the traction machine base 100. This can improve the installation stability of the traction machine base 100 in the shaft.

[0043] Here, the first plate 21 is connected to the shim block 40; the second plate 22 is used to support the traction machine 200; and the first plate 21 and the second plate 22 are connected and fixed to clamp the shock-absorbing pad 23.

[0044] It should be noted that the number of the aforementioned shock-absorbing pads 23 is four, and the four shock-absorbing pads 23 are located at the four corners of the base component 20, together supporting the traction machine 200 on the second plate 22. The specific structure of the aforementioned shock-absorbing pads 23 and the connection method between them and the first plate 21 and the second plate 22 can adopt conventional methods of existing technology, and will not be elaborated here.

[0045] In this embodiment, since the extension 210 supporting the traction machine 200 on the upper base assembly 20 is located outside the lower base assembly 10 in its width direction X, and the lower part of the extension 210 is not supported by the lower base assembly 10, the upper base assembly 20 is at risk of tipping over when supporting the traction machine 200.

[0046] Based on this, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the traction machine base 100 of this embodiment also includes a support rib 50, which has a first connecting portion 51 and a second connecting portion 52. The first connecting portion 51 is located below the extension 210 and abuts against and limits the extension 210. The second connecting portion 52 is used to fix to the shaft wall (not shown). In other words, the support rib 50 of this embodiment can provide reliable rigid support for the extension 210 of the component 20 on the base, which can effectively prevent the extension 210 from overturning or deforming due to load, thereby ensuring the stability of the overall structure of the traction machine base 100.

[0047] Furthermore, the supporting stiffener 50 is provided with a clearance groove 511, which is used to avoid the setting of the car upper beam 500. This ensures that the first connecting part 51 supports the extension 210 without interfering with the normal upward path of the car upper beam 500, which significantly enhances the support stability of the extension 210, thereby effectively improving the overall anti-overturning ability and structural reliability of the base assembly 20.

[0048] like Figure 3 , Figure 6 As shown, in one embodiment, the number of counterweight head plates 30 is configured to be two, so that the traction machine base 100 can be adapted to a double counterweight wheel structure.

[0049] like Figures 4 to 6 As shown, this application also provides an elevator, including a counterweight guide rail 300, a traction machine 200, and the aforementioned traction machine base 100; wherein, the lower base assembly 10 is mounted on the top of the counterweight guide rail 300; the traction machine 200 is mounted on the upper base assembly 20, and at least one fixed point 201 between the traction machine 200 and the upper base assembly 20 is disposed on the outer side of the lower base assembly 10 in its width direction X.

[0050] like Figures 6 to 8 As shown, in one embodiment, the elevator further includes a counterweight frame 400, which is slidably mounted on a counterweight guide rail 300. The counterweight frame 400 is rotatably mounted with at least two counterweight wheels 401, which correspond one-to-one with at least two counterweight rope head plates 30. Each counterweight wheel 401 is connected to the traction machine 200 and the corresponding counterweight rope head plate 30 via a counterweight rope (not shown).

[0051] Here, as Figure 8As shown, there are two counterweight rope head plates 30 and two counterweight sheaves 401, which allows the elevator to halve the structural thickness of the original counterweight sheaves. This reduces the overall thickness of the counterweight frame 400, thereby reducing its horizontal footprint in the hoistway. Of course, the number of counterweight rope head plates 30 and four counterweight sheaves 401 can also be four, etc., which will not be elaborated here.

[0052] like Figure 7 , Figure 8 As shown, in one embodiment, the counterweight frame 400 includes a straight beam 410 and an upper beam 420. The end of the upper beam 420 is disposed inside the straight beam 410 and connected to the straight beam 410; and at least two counterweight wheels 401 are rotatably mounted on the upper beam 420. This ensures that the mounting of the upper beam 420 on the straight beam 410 does not occupy space in the thickness direction of the counterweight frame 400, which helps to achieve a thinner counterweight frame 400 structure, thereby further improving the space utilization rate of the elevator in the horizontal direction of the hoistway.

[0053] Here, there are two straight beams 410, located at both ends of the upper beam 420. Each straight beam 410 has a box-like structure. Similarly, there are two upper beams 420. During installation, one upper beam 420 is first placed against the inner side of the same side wall of the two straight beams 410 and secured with fasteners 402. After the counterweight roller 401 is installed onto this upper beam 420, the other upper beam 420 is then installed onto the inner side of the other side wall of the two straight beams 410. Ultimately, the two upper beams 420 jointly support the counterweight roller 401, achieving balanced load bearing.

[0054] It should be noted that the installation method of the heavy roller 401 on the upper beam 420 can adopt the conventional method of existing technology, which will not be elaborated here.

[0055] Furthermore, the upper beam 420 is connected to the straight beam 410 via fasteners 402; the counterweight roller 401 is rotatably mounted on the upper beam 420 via a counterweight roller axle 4011, and the counterweight roller axle 4011 is located inside the fastener 402 in the thickness direction of the counterweight frame 400. That is, the counterweight roller axle 4011 does not exceed the outline of the fastener 402 in the thickness direction of the counterweight frame 400, thereby avoiding additional space occupation in this direction, which is conducive to minimizing the overall thickness of the counterweight frame 400 and achieving a more compact structural design.

[0056] Here, the fastener 402 is configured as a bolt, which is locked with a nut after passing through the straight beam 410 and the upper beam 420. Of course, in other embodiments, the fastener 402 may also be a pin or the like, which will not be elaborated here.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
