Abstract
Description
Technical Field
[0001] This utility model relates to the field of port machinery, and in particular to a through-shaft segmented rotating wire rope idler group. Background Technology
[0002] In existing technologies, multiple wire ropes are typically used in complex environments such as port machinery to lift or transport heavy objects. However, because different wire ropes have different working conditions (such as speed and direction), traditional idler roller sets often cannot meet the needs of all wire ropes, leading to excessive wear on some wire ropes, affecting the service life of the equipment and increasing maintenance costs. Utility Model Content
[0003] This application provides a through-shaft segmented rotating wire rope idler group, which solves the problem that in the prior art, due to the different working states (such as speed, direction, etc.) of different wire ropes, traditional idler groups often cannot meet the needs of all wire ropes, resulting in excessive wear of some wire ropes, affecting the service life of the equipment and increasing maintenance costs.
[0004] The technical solutions adopted in the embodiments of this application are as follows.
[0005] A segmented rotating wire rope idler assembly includes a shaft for supporting multiple idlers; ultra-high molecular weight polyethylene (UHMWPE) idlers a and b, mounted on the shaft, with each idler segmented along the axial direction of the shaft; bearings located inside each UHMWPE idler to enable independent rotation of the idlers; bearing housing a, bearing housing b, shaft sleeve a, shaft sleeve b, and a cover for protecting the bearings and their internal structure.
[0006] As a further improvement to the above technical solution:
[0007] The number of ultra-high molecular weight polyethylene rollers is adjusted according to the actual number and distribution requirements of the steel wire ropes.
[0008] It also includes a mounting base, through which the shaft is fixed to the port machinery equipment.
[0009] It also includes a retaining plate, which is used to fix the position of the shaft and prevent it from moving axially.
[0010] The bearing housing includes bearing housing a and bearing housing b, which are respectively installed on both sides of different sections of the idler roller.
[0011] The bushings include bushing a and bushing b, which are respectively disposed on the shaft between adjacent idler rollers to isolate idler rollers of different segments.
[0012] The bearing is a GBT276 bearing.
[0013] It also includes bolts (11, 14) for connecting the various components.
[0014] The transparent cover is located at both ends of the idler roller and is used to seal the bearing cavity to prevent dust and impurities from entering.
[0015] When multiple wire ropes contact different segments of idler rollers in different motion states, each segment of idler roller can independently respond to the motion state of the wire ropes through the bearings.
[0016] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:
[0017] 1. Due to the use of segmented idler rollers along the axial direction, with each segment rotating independently, when multiple wire ropes move at different speeds and directions, the corresponding segmented idler rollers can autonomously adjust their speed and direction according to the movement of the wire ropes. This "segmented independent response" mechanism avoids the sliding friction between the wire ropes and idler rollers caused by the forced coaxial rotation of traditional idler roller assemblies, making the wear rate of each wire rope more uniform and significantly reducing the risk of excessive local wear. It reduces wear by approximately 50% compared to traditional metal idler rollers and has self-lubricating properties, reducing fatigue damage to the wires on the surface of the wire ropes. Simultaneously, this material is resistant to seawater corrosion and impact, and is not prone to rusting or breakage in the high humidity and salt spray environment of ports, extending the overall service life of the idler roller assembly. Each segmented idler roller is isolated by bushings. When a segment of the idler roller wears out due to long-term use, the corresponding segment of the idler roller and bearing can be disassembled and replaced individually without disassembling the entire idler roller assembly. This modular design reduces maintenance workload by approximately 70% and lowers spare parts replacement costs, making it particularly suitable for rapid, non-stop maintenance of large equipment such as port machinery. The number of idlers can be adjusted as needed according to the actual number and distribution of wire ropes. Whether it is a single row of multiple ropes or a complex working condition with staggered arrangements, precise adaptation can be achieved by adding or removing segmented idlers. For example, in the lifting mechanism of a quay container crane, this idler group can simultaneously meet the different movement requirements of the main and auxiliary lifting wire ropes, avoiding the wire rope interference problem caused by the layout limitations of traditional idler groups.

[0021] This application provides a through-shaft segmented rotating wire rope idler group, which solves the problem that in the prior art, due to the different working states (such as speed, direction, etc.) of different wire ropes, traditional idler groups often cannot meet the needs of all wire ropes, resulting in excessive wear of some wire ropes, affecting the service life of the equipment and increasing maintenance costs.
[0022] The technical solution in this application embodiment is to solve the above problems, and the overall idea is as follows:
[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0024] A segmented rotating wire rope idler assembly includes a shaft 9 for supporting multiple idlers; ultra-high molecular weight polyethylene (UHMWPE) idlers a3 and b5, mounted on the shaft 9, with each idler segmented along the axial direction of the shaft 9; bearings 13 located inside each UHMWPE idler to enable independent rotation of the idlers; and bearing sleeves a4, b10, a6, b7, and a cover 2 for protecting the bearings 13 and their internal structures.
[0025] The number of ultra-high molecular weight polyethylene idlers is adjusted according to the actual number and distribution requirements of the steel wire ropes.
[0026] It also includes a mounting base 1, through which the shaft 9 is fixed to the port machinery equipment.
[0027] It also includes a shaft retaining plate 8, which is used to fix the position of the shaft 9 and prevent it from moving axially.
[0028] The bearing housing includes bearing housing a4 and bearing housing b10, which are respectively installed on both sides of the idler roller in different sections.
[0029] The bushings include bushing a6 and bushing b7, which are respectively disposed on the shaft 9 between adjacent idler rollers to isolate idler rollers of different segments.
[0030] Bearing 13 is a GBT276 bearing.
[0031] It also includes bolts (11, 14) for connecting the various components.
[0032] The cover 2 is located at both ends of the idler roller to seal the bearing cavity and prevent dust and impurities from entering.
[0033] When multiple wire ropes contact different segments of idler rollers in different motion states, each segment of idler roller can independently respond to the motion state of the wire ropes through bearing 13.
[0034] Because the idler rollers are segmented along shaft 9 and each segment rotates independently, when multiple wire ropes move at different speeds and directions, the corresponding segment idler rollers can autonomously adjust their speed and direction according to the movement of the wire ropes. This "segmented independent response" mechanism avoids the sliding friction between the wire ropes and idler rollers caused by the forced coaxial rotation of traditional idler roller assemblies, making the wear rate of each wire rope more uniform and significantly reducing the risk of excessive local wear. The wear is reduced by approximately 50% compared to traditional metal idler rollers, and the material has self-lubricating properties, reducing fatigue damage to the wires on the surface of the wire ropes. Simultaneously, this material is resistant to seawater corrosion and impact, and is not prone to rusting or breakage in the high humidity and salt spray environment of ports, extending the overall service life of the idler roller assembly. Each segment idler roller is isolated by shaft 9 bearings. When a segment idler roller wears out due to long-term use, the corresponding segment idler roller and shaft 9 bearings can be disassembled and replaced individually without disassembling the entire idler roller assembly. This modular design reduces maintenance workload by approximately 70% and lowers spare parts replacement costs, making it particularly suitable for rapid, non-stop maintenance of large equipment such as port machinery. The number of idlers can be adjusted as needed according to the actual number and distribution of wire ropes. Whether it is a single row of multiple ropes or a complex working condition with staggered arrangements, precise adaptation can be achieved by adding or removing segmented idlers. For example, in the lifting mechanism of a quay container crane, this idler group can simultaneously meet the different movement requirements of the main and auxiliary lifting wire ropes, avoiding the wire rope interference problem caused by the layout limitations of traditional idler groups.
