[0003] However, due to the large number of parts in wire rope fixing assemblies, existing technologies typically include large and small pressure plates, as well as multiple fasteners and support components such as metal frames, beams, and connectors. These components work together to secure the wire rope. This requires assemblers to spend more time and effort ensuring the correct installation of each part, increasing manufacturing time, processing difficulty, and assembly time. Utility Model Content

[0004] The main objective of this invention is to provide a rope clamping assembly and a lift having the same, in order to solve the problem that the existing lift has a large number of parts for fixing the wire rope, resulting in low assembly efficiency.

[0005] To achieve the above objectives, according to one aspect of the present invention, a rope clamping assembly is provided for use in a lift.

[0013] Furthermore, the mounting base is provided with two positioning plates, which are located on both sides of the positioning rod. The positioning plates are provided with arc-shaped grooves. The fixed end of the wire rope passes through one arc-shaped groove, a clamping hole and another arc-shaped groove in sequence before being clamped by the positioning rod. The outer peripheral wall of the wire rope contacts the groove wall of the arc-shaped groove.

[0014] According to another aspect of the present invention, a lifting machine is provided, including the rope clamping assembly mentioned above.

[0015] This invention provides a rope clamping assembly for use in a lift. The lift includes a support platform for carrying vehicles and vertically movable.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] To address the problem of low assembly efficiency caused by the large number of components in the wire rope fixing structure of existing lifting machines, this utility model provides a rope clamping assembly and a lifting machine incorporating the same.

[0025] Please refer to Figures 1 to 3 As shown, one aspect of the technical solution of this utility model provides a rope clamping assembly applied to a lift. The lift includes a support platform 1 for carrying vehicles and vertically movable. A groove 2 is provided on the bottom surface of the support platform 1 along its extension direction. Grooves are provided on the two side walls of the groove 2 along their extension directions. The rope clamping assembly includes a connecting body 10, a rope clamping component 20, and a guide component 30. The connecting body 10 is disposed in the groove 2 and is used to connect to the driving end of the drive component 3. The rope clamping component 20 is disposed on the connecting body 10 and is used to clamp the fixed end of the wire rope. The guide component 30 includes a guide plate 31 and guide members 32 detachably disposed at both ends of the guide plate 31. The guide plate 31 is disposed on the connecting body 10. At least a portion of the two guide members 32 is located in the groove and contacts the inner wall of the groove, so that when the drive component 3 drives the connecting body 10 to move along the extension direction of the groove 2, the guide members 32 slide in the groove.

[0026] By adopting the technical solution of this application, the structure of the rope clamping assembly is simplified and the number of parts is reduced by eliminating complex parts such as large and small pressure plates and using a structure of guide plate 31 combined with guide component 32. This design reduces the processing difficulty and shortens the assembly time, thereby improving the overall assembly efficiency of the lift and solving the problem of low assembly efficiency caused by the large number of parts in the wire rope fixing structure of the existing technology. At the same time, the use of detachable guide component 32 to cooperate with the grooves on both sides of the slide 2 ensures the stable guidance and sliding of the rope clamping assembly in the slide 2, improving the stability and safety of the lift operation. The detachable design also allows for quick replacement of worn guide component 32 after long-term use without disassembling the entire rope clamping assembly, reducing maintenance costs and time consumption.

[0027] In this embodiment, the guide 32 is a slider 33.

[0028] Compared to existing technologies that utilize large and small plate parts such as guide plates, this application, through the design of guide members 32 and guide plates 31 for slider 33, enables low-friction sliding within the groove, thereby reducing wear between guide member 30 and the inner wall of the groove 2, extending the service life of the component, and reducing the time required for processing and assembling multiple parts as in existing technologies, significantly improving assembly efficiency.

[0029] In this embodiment, the slider 33 is provided with two first connecting holes, and the end of the guide plate 31 is provided with two corresponding second connecting holes. The first connecting holes and the second connecting holes are detachably connected by bolts or pins. In this way, the slider 33 and the guide plate 31 become independent modules. When the slider 33 is worn or damaged, it can be quickly and easily disassembled and replaced with a new slider 33 without disassembling the entire guide component 30 or the rope clamping assembly, which greatly reduces maintenance time and cost. Moreover, the use of bolts or pins as connecting parts makes the installation and disassembly process simple and quick, without the need for special tools, reducing assembly difficulty and improving production efficiency.

[0030] Optionally, the slider 33 has a first mating part extending perpendicular to the groove 2, and the end of the guide plate 31 has a second mating part extending perpendicular to the groove 2. The first mating part and the second mating part are connected in a compatible manner. One of the first and second mating parts is a positioning groove, and the other is a positioning protrusion. This arrangement ensures a precise connection between the slider 33 and the guide plate 31, preventing malfunctions caused by loose connections when the slider 33 moves along the groove's extension direction, thus guaranteeing a stable connection between the slider 33 and the guide plate 31. Compared to using screws or pins, the mating connection of the positioning groove and the positioning protrusion is generally easier to align and assemble, especially in confined or hard-to-access locations, reducing assembly time and labor costs. Furthermore, this connection method allows the slider 33 to be replaced without damaging the original structure; simply remove the positioning protrusion from the positioning groove without disassembling other components or using additional tools, simplifying maintenance and upkeep.

[0031] In this embodiment, at least a portion of the surface of the slider 33 is provided with a lubricating layer, which contacts the groove wall; wherein the lubricating layer is made of polyethylene material. In this way, the polyethylene material of the lubricating layer can absorb and disperse the impact and wear of the slider 33 during sliding, protecting the slider 33 from direct contact wear with the groove wall, extending the service life of both, and reducing equipment maintenance costs.

[0032] Optionally, the slider 33 is made of polyethylene. Made of UHMW-PE, the slider 33 possesses extremely high wear resistance. During repeated lifting and lowering of the lift, the slider 33 continuously contacts and rubs against the inner wall of the groove. The high wear resistance of UHMW-PE effectively extends the service life of the slider 33 and reduces maintenance frequency. Furthermore, it has good self-lubricating properties, allowing the slider 33 to maintain low friction even without lubricating oil when moving within the groove, reducing wear and energy loss during operation and improving system efficiency and stability. It also has excellent impact resistance, making it less prone to breakage or deformation even under strong physical impacts, thus improving the durability of the slider 33 under complex working conditions.

[0033] In this embodiment, the groove has a preset depth, and the slider 33 has a preset length along the direction of extending into the groove. The preset depth H and the preset length L satisfy the following condition: L = (1.5-2)H.

[0034] By ensuring that the length of the slider 33 is at least 1.5 times the depth of the groove, the contact area between the slider 33 and the inner wall of the groove can be increased, thereby improving the stability of the connecting body 10 within the slide groove 2, reducing swaying and offset during movement, and improving the operating accuracy of the rope clamping assembly. Furthermore, the longer length of the slider 33 more effectively restricts its lateral movement within the groove along a direction perpendicular to the groove's extension, preventing the slider 33 from detaching from the groove due to external forces during lift operation, ensuring equipment safety. Additionally, the longer slider 33 better guides the linear movement of the connecting body 10 within the groove, maintaining smooth sliding even under high-speed operation and load variations, thus improving the guiding accuracy of the guide component 30.

[0035] Optionally, the guide 32 can be a pulley or a fixing block adapted to the shape of the groove.

[0036] Compared to sliding, the rollers rolling within the groove significantly reduce the coefficient of friction and energy loss, resulting in smoother lifting and lowering of the support platform 1 and improved operating efficiency. Furthermore, the rolling friction of the rollers is far less than the sliding friction, reducing wear between the guide component 32 and the inner wall of the groove, thus extending the service life of both and the entire rope clamping assembly. However, the roller design is not as well adapted to the structural characteristics of the groove as the slider 33, making it prone to wheel deviation or wobbling during movement.

[0037] The tight fit between the fixing block and the groove increases the structural rigidity between the support platform 1 and the drive assembly 3, which helps to improve the platform's load-bearing capacity and stability. Compared to pulleys, the design and manufacture of fixing blocks are generally simpler and less expensive, which is beneficial for mass production and maintenance. However, the contact area between the fixing block and the inner wall of the groove is larger than that of the slider 33, resulting in a higher coefficient of friction, making it difficult to adapt to long-term high-speed operation.

[0038] Specifically, the rope clamping component 20 includes a mounting plate 21 and a clamping member 22. The mounting plate 21 is disposed on the connecting body 10. The clamping member 22 is disposed on the mounting plate 21, and at least a portion of the clamping member 22 forms a clamping hole 23 for the fixed end of the wire rope to extend into. At least a portion of the clamping member 22 is movably disposed to contract or expand the clamping hole 23 to fix or separate the fixed end of the wire rope. Thus, by controlling at least a portion of the clamping member 22, the size of the clamping hole 23 can be quickly adjusted, thereby facilitating the fixing or separation of the wire rope, improving the efficiency of wire rope fixing and disassembly, and shortening assembly time. Furthermore, by controlling the size of the clamping hole 23, it can accommodate wire ropes of different diameters, improving the versatility and flexibility of the rope clamping assembly. When it is necessary to replace the wire rope or check its tightness, the movable clamping member 22 makes this process simpler, reducing maintenance time and costs, and also facilitating daily inspection and maintenance.

[0039] In this embodiment, there are two mounting plates 21, which are arranged opposite to each other on the connecting body 10. Each mounting plate 21 is provided with two clamping members 22, so that the four steel wire ropes are clamped by the four clamping members 22 respectively.

[0040] Specifically, the clamping component 22 includes a mounting base 220 and a positioning rod 222. The mounting base 220 is disposed on the mounting plate 21, and the mounting base 220 is provided with two first mounting holes 221 respectively. The mounting plate 21 is provided with two corresponding second mounting holes. The positioning rod 222 is U-shaped and forms a clamping hole 23. Both ends of the positioning rod 222 have threaded sections. The two ends of the positioning rod 222 pass through the first mounting hole 221 and the second mounting hole respectively and are connected to the threaded sections by a nut, so as to fix or separate the fixed end of the wire rope by tightening or loosening the nut.

[0041] The above-described configuration, where both ends of the U-shaped positioning rod 222 are secured to its threaded sections with nuts, forms a mechanical locking mechanism. This ensures that the fixed end of the wire rope is firmly clamped within the clamping hole 23 formed by the positioning rod 222, maintaining stability even under heavy loads or vibrations, and reducing the risk of wire rope slippage or detachment. Furthermore, by tightening or loosening the nuts, the operator can adjust the tightness of the positioning rod 222 on the wire rope. This adjustability ensures appropriate tightening force regardless of the wire rope diameter, avoiding damage caused by over-tightening or safety hazards caused by insufficient tightening. The U-shaped positioning rod 222 is threadedly connected to the mounting base 220 and mounting plate 21, allowing for disassembly and installation without special tools, greatly improving the efficiency of wire rope replacement or repair and reducing maintenance costs.

[0042] Compared to the traditional design with multiple fasteners and pressure plates, the combination of U-shaped positioning rod 222 and nut greatly simplifies the structure of clamping component 22, reduces the number of parts and weight, and lowers material and manufacturing costs.

[0043] Specifically, the mounting base 220 is equipped with two positioning plates 223, located on either side of the positioning rod 222. Each positioning plate 223 has an arc-shaped groove 224. The fixed end of the wire rope passes sequentially through one arc-shaped groove 224, the clamping hole 23, and the other arc-shaped groove 224 before being clamped by the positioning rod 222. The outer circumferential wall of the wire rope contacts the groove wall of the arc-shaped groove 224. This design of the arc-shaped groove 224 helps operators quickly and accurately place the fixed end of the wire rope in the predetermined position, reducing alignment errors during installation and improving assembly accuracy, especially noticeable when working in confined spaces. Furthermore, based on the initial positional definition provided by the arc-shaped groove 224 for the fixed end of the wire rope, the clamping action of the U-shaped positioning rod 222 creates a multi-layered fixing structure, greatly enhancing the stability and reliability of the wire rope fixation and reducing the probability of displacement or loosening during use.

[0044] According to another aspect of the present invention, a lifting machine is provided, including the rope clamping assembly mentioned above.

[0045] Compared to the multi-part processing and assembly in the prior art, the optimization of this application, through the design of the guide plate 31 and the guide component 32, not only ensures the firm fixation and stable guidance of the wire rope, but also solves the problem of low assembly efficiency caused by the large number of parts in the wire rope fixing structure of the existing lifting machine, which simplifies the assembly and maintenance process and extends the service life of the lifting machine.

[0046] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0047] The rope clamping assembly is used in a lift, which includes a support platform 1 for carrying vehicles and vertically movable. A groove 2 is provided on the bottom surface of the support platform 1 along its extending direction. Grooves are provided on the two side walls of the groove 2 along their extending directions. The rope clamping assembly includes a connecting body 10, a rope clamping component 20, and a guide component 30. The connecting body 10 is disposed within the groove 2 and is used to connect to the drive end of a drive assembly 3. The rope clamping component 20 is disposed on the connecting body 10 and is used to clamp the fixed end of a wire rope. The guide component 30 includes a guide plate 31 and guide members 32 detachably disposed at both ends of the guide plate 31. The guide plate 31 is disposed on the connecting body 10. At least portions of the two guide members 32 are located within the grooves and contact the inner walls of the grooves, so that when the drive assembly 3 drives the connecting body 10 to move along the extending direction of the groove 2, the guide members 32 slide within the grooves. By adopting the technical solution of this application, the structure of the rope clamping assembly is simplified and the number of parts is reduced by eliminating complex parts such as large and small pressure plates and using a structure of guide plate 31 combined with guide component 32. This design reduces the processing difficulty and shortens the assembly time, thereby improving the overall assembly efficiency of the lift and solving the problem of low assembly efficiency caused by the large number of parts in the wire rope fixing structure of the existing technology. At the same time, the use of detachable guide component 32 to cooperate with the grooves on both sides of the slide 2 ensures the stable guidance and sliding of the rope clamping assembly in the slide 2, improving the stability and safety of the lift operation. The detachable design also allows for quick replacement of worn guide component 32 after long-term use without disassembling the entire rope clamping assembly, reducing maintenance costs and time consumption.
