Description

Technical Field

[0001] This utility model relates to the field of lifting device technology, and in particular to a ladder fixing device, ladder equipment and lifting system. Background Technology

[0002] Wind power generation is a method of generating electricity by using wind turbine generators to convert the kinetic energy of wind into mechanical energy, and then the generator converts the mechanical energy into electrical energy and transmits it to the power grid. With the rapid development of my country's economic construction, wind power generation is receiving more and more attention.

[0003] Existing wind turbine generator sets generally include a rotor, nacelle, and tower. The tower supports the nacelle to the required height, and a ladder is installed inside the tower to facilitate the lifting and lowering of equipment or manual climbing. Existing technology provides a herringbone structure support for fixing the ladder to ensure its stability. However, at least one of the three struts of the herringbone structure of this support must pass through the center of the tower, which inevitably causes positional interference with the lifting and lowering process of the equipment. This means that this type of support can only serve manual climbing and greatly hinders the system design of the lifting equipment. Utility Model Content

[0004] The first aspect of this utility model provides a ladder fixing device to solve the positional interference defect between the A-frame support and the lifting equipment in the prior art. While ensuring the stability of the ladder fixing components, it can effectively reduce the volume of the ladder fixing device, solve the positional interference problem between the A-frame support and the lifting equipment, and effectively improve the versatility of the ladder fixing device.

[0005] The second aspect of this utility model provides a ladder climbing device.

[0006] The third aspect of this utility model provides a lifting system.

[0007] The ladder fixing device provided by this utility model includes a first support member, two first adsorption components and two second adsorption components. The two first adsorption components are respectively disposed at both ends of the first support member. The adsorption ends of the two second adsorption components are spaced apart on the same side of the first support member and located between the two first adsorption components. The adsorption ends of the two first adsorption components and the adsorption ends of the two second adsorption components are arranged along the same preset arc.

[0008] According to the ladder fixing device provided by this utility model, the second adsorption component includes a second support member and a second magnetic member. The second support member is cross-connected with the first support member. The second magnetic member is disposed at one end of the second support member close to the preset arc. The end of the second support member away from the preset arc is used to fix the ladder.

[0009] The ladder fixing device provided by this utility model further includes a third support member, one end of which is connected to the first adsorption component, and the other end of which is connected to the second support member on the same side as the first adsorption component.

[0010] According to the ladder fixing device provided by this utility model, the second adsorption component further includes a second connecting seat, which is used to connect the second support member and the second magnetic member.

[0011] The upper surface of the second connector is provided with a plurality of second connecting holes, and the third support member can be selected to connect to the second connector through one of the plurality of second connecting holes.

[0012] According to the ladder fixing device provided by this utility model, the first adsorption component includes a first magnetic suction member and a first connecting seat. The first connecting seat is disposed at the end of the first support member, and the first magnetic suction member is disposed on the side of the first connecting seat facing the preset arc.

[0013] According to the ladder fixing device provided by this utility model, the upper surface of the first connecting seat is provided with a threaded hole, and the first connecting seat is adapted to be fastened to the first support member through the threaded hole.

[0014] According to the ladder fixing device provided by this utility model, the upper surface of the first connecting seat is provided with a plurality of first connecting holes, and the third support member can be selected to connect to the first connecting seat through one of the plurality of first connecting holes.

[0015] The ladder fixing device provided by this utility model further includes a connector, which is connected to the first support and located at the center line of the first support. One end of the connector is used to fix one of the two second adsorption components, and the other end of the connector is used to fix the other of the two second adsorption components.

[0016] The climbing ladder device provided by this utility model includes multiple climbing ladder sections, welded supports, and climbing ladder fixing devices as described in any of the preceding claims. The multiple climbing ladder sections are connected end to end. The welded supports are located at the ends of each climbing ladder section. The climbing ladder fixing devices are located on the climbing ladder sections and are spaced apart from the welded supports. The welded supports are used to connect to the tower.

[0017] The lifting system provided by this utility model includes the aforementioned ladder device.

[0018] When the ladder fixing device is applied inside the tower to fix the ladder, the ladder will generate vertical and lateral loads on the ladder fixing device. In the ladder fixing device provided by this utility model, since the two first adsorption components at both ends of the first support member can be adsorbed and connected to the inner wall of the tower, the load on the first support member will be evenly distributed to the two first adsorption components, thereby making the ladder fixing device firmly fixed to the inner wall of the tower and providing a safe and stable support force for the ladder.

[0019] Furthermore, the inner wall of the tower is an arc surface. The ladder fixing device provided in this embodiment of the invention, by setting two second adsorption components and arranging the adsorption ends of the two second adsorption components along a preset arc on one side of the first support member, ensures more uniform stress transmission between the ladder fixing device and the inner wall of the tower due to the compatibility of the preset arc with the arc surface of the inner wall of the tower. This makes the connection between the ladder fixing device and the tower more stable. From another perspective, by setting the second adsorption components, there are more contact points and a wider contact area between the ladder fixing device and the inner wall of the tower. This makes the ladder fixing device stronger in load-bearing capacity and more stable, ensuring the safety of the ladder during use.

[0020] Compared to existing technologies, the ladder fixing device provided by this utility model, by setting two second adsorption components on the same side of the first support member and aligning the adsorption ends of the two first adsorption components and the two second adsorption components along the same preset arc, ensures that when the ladder fixing device is applied inside the tower, it only fixes itself along a local area of ​​the tower's inner wall, without crossing the center of the tower. Compared to existing A-frame support structures, when the ladder fixing device is used with lifting equipment, it does not interfere with the lifting equipment's position. In other words, the ladder fixing device can be used not only for manual climbing but also for lifting equipment, effectively improving its versatility. Furthermore, because the ladder fixing device requires little installation space, it is also highly advantageous for installing other decorative components inside the tower, allowing for higher space utilization within the tower.

[0033] Figure 1 This is a schematic diagram of the ladder fixing device provided in an embodiment of the present invention from one perspective; Figure 2 This is a structural schematic diagram of the ladder fixing device provided in an embodiment of the present invention from another perspective.

[0034] See Figure 1 and Figure 2 In an optional embodiment of the present invention, the ladder fixing device 40 includes a first support member 100, two first adsorption components 200 and two second adsorption components 300. One of the two first adsorption components 200 is disposed at one end of the first support member 100, and the other of the two first adsorption components 200 is disposed at the other end of the first support member 100.

[0035] Two second adsorption components 300 are respectively cross-connected to the first support 100, and the adsorption ends of the two second adsorption components 300 are spaced apart on the same side of the first support 100. In addition, the adsorption ends of the two first adsorption components 200 and the two second adsorption components 300 are arranged along the same preset arc. It should be noted that the length of the first support 100 matches the length of the preset arc. The preset arc can be adaptively designed according to the curvature of the actual installation area. For example, when the installation area is the tower 10, it can be adaptively set according to the curvature of the inner wall of the tower 10.

[0036] As the name suggests, the first adsorption component 200 and the second adsorption component 300 are connected to the area to be installed by adsorption. There are various adsorption connection methods, such as magnetic connection, negative pressure adsorption, or adhesive bonding. Specifically, the method can be adapted according to the actual situation. When the ladder fixing device 40 is used to fix the ladder, the ladder can be located on the side of the first support member 100 away from the preset arc, or on the side of the second adsorption component 300 away from the preset arc.

[0037] See Figure 1 and Figure 2 It is understandable that when the ladder fixing device 40 is applied inside the tower 10 and used to fix the ladder, the ladder will generate vertical and lateral loads on the ladder fixing device 40. In the ladder fixing device 40 provided in this embodiment of the present invention, since the two first adsorption components 200 at both ends of the first support member 100 can be adsorbed and connected to the inner wall of the tower 10 respectively, the load on the first support member 100 will be evenly distributed to the two first adsorption components 200, thereby making the ladder fixing device 40 firmly fixed on the inner wall of the tower 10 and providing a safe and stable support force for the ladder.

[0038] Furthermore, the inner wall of the tower 10 is an arc surface. The ladder fixing device 40 provided in this embodiment of the invention, by setting two second adsorption components 300, and arranging the adsorption ends of the two second adsorption components 300 and the adsorption ends of the two first adsorption components 200 along a preset arc on one side of the first support member 100, ensures a more uniform stress transmission between the ladder fixing device 40 and the inner wall of the tower 10, based on the compatibility between the preset arc and the arc surface of the inner wall of the tower. This makes the connection between the ladder fixing device 40 and the tower 10 more stable. From another perspective, by setting the second adsorption components 300, there are more contact points and a wider contact area between the ladder fixing device 40 and the inner wall of the tower 10. This makes the ladder fixing device 40 have a stronger load-bearing capacity and better stability, ensuring the safety of the ladder during use.

[0039] Compared to existing technologies, the ladder fixing device 40 provided in this embodiment of the invention, by setting two second adsorption components 300 on the same side of the first support member 100 and arranging the adsorption ends of the two first adsorption components 200 and the two second adsorption components 300 along the same preset arc, ensures that when the ladder fixing device 40 is applied inside the tower 10, it will only be fixed along a local area of ​​the inner wall of the tower 10, without crossing the center of the tower 10. Compared to existing herringbone structure supports, when the ladder fixing device 40 is used for lifting equipment, it will not interfere with the lifting equipment's position. In other words, the ladder fixing device 40 can be used not only for manual climbing but also for lifting equipment, effectively improving its versatility. Furthermore, because the ladder fixing device 40 requires little installation space, this is also highly advantageous for the installation of other decorative components inside the tower 10, allowing for higher space utilization inside the tower 10.

[0040] Continue reading Figure 1 and Figure 2 In an optional embodiment of this utility model, the second adsorption component 300 includes a second support member 310 and a second magnetic suction member 320. The second support member 310 is cross-connected with the first support member 100. The end of the second support member 310 near the preset arc is used to set the second magnetic suction member 320, so as to ensure that the adsorption end of the second magnetic suction member 320 and the adsorption end of the first adsorption component 200 are on the same preset arc. The end of the second support member 310 away from the preset arc is used to fix the ladder. Specifically, the end of the second support member 310 away from the preset arc is provided with a connecting component adapted to the ladder. The ladder can be fixed to the end of the second support member 310 away from the preset arc by means of fastener connection, that is, the ladder can be fixed to the end of the first support member 100 away from the preset arc.

[0041] Understandably, the inner wall of the tower 10 is a pure steel structure. By setting the second magnetic suction component 320, the ladder fixing device 40 can be installed on the tower 10 through magnetic connection. In this way, on the one hand, the magnetic connection does not require welding of the tower 10. During the installation and disassembly of the ladder fixing device 40, the surface of the tower 10 will not be damaged, thus eliminating the threat of welding and ensuring the integrity and structural strength of the tower 10. At the same time, it also eliminates the need for thickening treatment of the tower 10 due to welding, which can effectively reduce the cost required for fixing the ladder. On the other hand, it can also make the ladder fixing device 40 and the steel properties of the tower 10 itself work together.

[0042] In addition, the magnetic connection method is easy to install and disassemble. During the assembly process, the position of the second magnetic component 320 can be flexibly adjusted as needed, which makes the ladder fixing device 40 more flexible to meet different working environments and actual needs. Furthermore, in terms of later maintenance, the second magnetic component 320 is easy to disassemble and replace, which can effectively reduce the maintenance cost of the ladder fixing device 40.

[0043] In addition, the second support member 310 and the second magnetic suction member 320 are independent components. In this way, under the premise that the second magnetic suction member 320 and the first adsorption component 200 are set with the same preset arc, the difficulty of manufacturing, design and transportation of the second adsorption component 300 can be reduced, and the production efficiency and installation efficiency of the ladder fixing device 40 can be effectively improved.

[0044] In addition, the end of the second support member 310 away from the preset arc is used to fix the ladder. In this way, when the ladder fixing device 40 is used inside the tower 10, the ladder can be oriented towards the center of the tower 10, which can provide more room for movement during manual climbing and lifting by the lifting equipment. This setting is beneficial to the safety of manual climbing and also to the volume optimization design of the lifting equipment, thereby increasing the upper limit of the lifting equipment's carrying capacity.

[0045] Continue reading Figure 1 and Figure 2 In an optional embodiment of this utility model, the ladder fixing device 40 further includes a third support member 400. One end of the third support member 400 is connected to the first adsorption component 200, and the other end of the third support member 400 is connected to a second support member 310 disposed on the same side as the first adsorption component 200. It can be understood that by setting the third support member 400, the third support member 400, the second support member 310, and the first support member 100 can form a triangular support structure. The triangular support structure has good stability and can effectively improve the load limit of the ladder fixing device 40.

[0046] Continue reading Figure 1 and Figure 2 In an optional embodiment of the present invention, the second adsorption component 300 further includes a second connecting seat 330, which is used to connect the second support member 310 and the second magnetic member 320. The upper surface of the second connecting seat 330 is provided with a plurality of vertical second connecting holes 331. The third support member 400 can select one of the plurality of second connecting holes 331 to connect with the second connecting seat 330, thereby realizing the connection with the second support member 310.

[0047] It is understandable that by setting the second connecting seat 330 to connect the second magnetic suction member 320 and the second support member 310, the connection area between the second support member 310 and the second magnetic suction member 320 can be increased, and the stress transmission relationship between the two can be optimized. In addition, by setting multiple vertical second connecting holes 331 to connect the third support member 400, during the installation process, on the one hand, the position of the aforementioned triangular structure can be flexibly adjusted by matching the second connecting holes 331 at different positions, so that the ladder fixing device 40 can be adapted to more different installation environments. On the other hand, since the second connecting holes 331 are vertical, the angle of the second connecting seat 330 relative to the third support member 400 can be flexibly adjusted during the installation process, that is, the angle of the second magnetic suction member 320 can be adjusted. In this way, by changing the angle of the second magnetic suction member 320, the fit between the ladder fixing device 40 and the inner wall of the tower 10 can be improved, thereby making the stability and firmness of the ladder fixing device 40 better.

[0048] Continue reading Figure 1 and Figure 2 In an optional embodiment of the present invention, the first adsorption component 200 includes a first magnetic suction member 210 and a first connecting seat 220. The first connecting seat 220 is disposed at the end of the first support member 100, and the first magnetic suction member 210 is disposed on the side of the first connecting seat 220 facing the preset arc. The first connecting seat 220 is also connected to the third support member 400.

[0049] It is understandable that, similar to the aforementioned second magnetic 320, the inner wall of the tower 10 is a pure steel structure. By setting the first magnetic 210, the ladder fixing device 40 can be installed on the tower 10 through magnetic connection. In this way, on the one hand, there is no need to weld the tower 10. During the installation and disassembly of the ladder fixing device 40, the threat of welding is eliminated, and the surface of the tower 10 will not be damaged, which can ensure the integrity and structural strength of the tower 10. At the same time, it also eliminates the need for thickening treatment of the tower 10 due to welding, which can effectively reduce the cost of fixing the ladder. On the other hand, it can also make the ladder fixing device 40 and the steel properties of the tower 10 itself work together.

[0050] In addition, the magnetic connection method is easy to install and disassemble. During the assembly process, the position of the first magnetic component 210 can be flexibly adjusted as needed, which makes the ladder fixing device 40 more flexible to meet different working environments and actual needs. In addition, in terms of later maintenance, the first magnetic component 210 is easy to disassemble and replace, which can effectively reduce the maintenance cost of the ladder fixing device 40.

[0051] Continue reading Figure 1 and Figure 2In an optional embodiment of this utility model, the upper surface of the first connecting seat 220 is provided with a vertically threaded hole 221. The first connecting seat 220 is adapted to be fastened to the first support member 100 through the threaded hole 221. It can be understood that by providing the vertically threaded hole 221, the angle of the first connecting seat 220 relative to the first support member 100 can be flexibly adjusted during the installation process, that is, the angle of the first magnetic suction member 210 can be adjusted. In this way, the fit between the ladder fixing device 40 and the inner wall of the tower 10 can be improved by changing the angle of the first magnetic suction member 210, thereby making the stability and firmness of the ladder fixing device 40 better.

[0052] Continue reading Figure 1 and Figure 2 In an optional embodiment of this utility model, the upper surface of the first connecting seat 220 is further provided with a plurality of vertical first connecting holes 222. The third support member 400 can choose one of the plurality of first connecting holes 222 to connect with the first connecting seat 220. It can be understood that by setting a plurality of vertical first connecting holes 222 to connect the third support member 400, during the installation process, on the one hand, the position of the aforementioned triangular structure can be flexibly adjusted by matching the first connecting holes 222 at different positions, so that the ladder fixing device 40 can be adapted to more different installation environments. On the other hand, since the first connecting holes 222 are vertical, the angle of the first connecting seat 220 relative to the third support member 400 can be flexibly adjusted during the installation process, that is, the angle of the first magnetic suction member 210 can be adjusted. In this way, by changing the angle of the first magnetic suction member 210, the fit between the ladder fixing device 40 and the inner wall of the tower 10 can be improved, thereby making the stability and firmness of the ladder fixing device 40 better.

[0053] Continue reading Figure 1 and Figure 2 In an optional embodiment of the present invention, the ladder fixing device 40 further includes a connector 500, which is connected to the first support member 100 and located at the center line of the first support member 100. One end of the connector 500 is used to fix one of the two second adsorption components 300, and the other end of the connector 500 is used to fix the other of the two second adsorption components 300.

[0054] It is understood that by connecting the two second adsorption components 300 with a connector 500 at the centerline of the first support 100, the two second adsorption components 300 can be symmetrically arranged along the centerline of the first support 100. This ensures that the load transmitted from the first support 100 to the two second adsorption components 300 is the same, and the stress transmission between each adsorption end on the preset arc and the tower 10 is more uniform, avoiding the problem of stress concentration. In an optional embodiment of this utility model, the connector 500 can be set as a plate-shaped part, which can increase the stress transmission area between the first support 100 and the two second adsorption components 300, thereby increasing the upper limit of the load of the ladder fixing device 40.

[0055] Figure 3 This is a schematic diagram of the structure of the ladder device provided in this embodiment of the utility model; Figure 4 yes Figure 3 Enlarged schematic diagram of the local structure at point A; Figure 5 yes Figure 3 A magnified view of the local structure at point B.

[0056] See Figures 3 to 5 The second aspect of this utility model provides a climbing ladder device, which includes multiple climbing ladder sections 20, welded supports 30, and climbing ladder fixing devices 40 as described in any of the foregoing embodiments. The multiple climbing ladder sections 20 are connected end to end to form a ladder, which can be climbed manually or raised and lowered by a lifting device. The welded supports 30 are located at the end of each climbing ladder section 20, that is, the welded supports 30 are located at the joint of two adjacent climbing ladder sections 20. The climbing ladder fixing devices 40 are located on the climbing ladder sections 20 and are spaced apart from the welded supports 30. Both the welded supports 30 and the climbing ladder fixing devices 40 are used to connect to the tower 10.

[0057] It should be noted that the length of the ladder section 20 matches the length of the tower section inside the tower 10. Understandably, to ensure connection strength, the connection between two adjacent tower sections inside the tower 10 is generally thickened, meaning the wall thickness at the end of the tower section is thicker than the wall thickness of other parts of the tower section. When the ladder equipment is installed inside the tower 10, since the length of the ladder section 20 matches the length of the tower section, the connection point between the welded support 30 and the tower 10 will be located exactly at the end of the tower section. The wall thickness at the end of the tower section can meet the welding requirements, and no additional thickening is needed. In this way, another layer of stable connection protection can be provided for the ladder equipment on the basis of the ladder fixing device 40.

[0058] A third aspect of this utility model provides a lifting system, which includes a lift and a ladder device as described in the foregoing embodiments. The ladder device is used for the lift to perform lifting movements. It is understood that because the lifting system provided in this application includes the ladder device described in the foregoing embodiments and the ladder fixing device 40 described in any of the foregoing embodiments, the lifting system also has the beneficial effects of the foregoing ladder device and the foregoing ladder fixing device 40. For specific beneficial effects, please refer to the foregoing description, which will not be repeated here.

[0059] It should be noted that the technical solutions in the various embodiments of this utility model can be combined with each other, but the basis for such combination is that they can be implemented by those skilled in the art. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist, that is, it is not within the protection scope of this utility model.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
