Description

Technical Field

[0001] This utility model relates to the field of elevator traveling cable technology, specifically to an anti-sway device for elevator traveling cables. Background Technology

[0002] The authorization announcement number CN214828151U discloses an anti-sway device for elevator traveling cables, which includes an elevator shaft, a guide groove is provided on the inner side wall of the elevator shaft, a traveling cable is installed inside the elevator shaft, and a guide mechanism is installed between the guide groove and the traveling cable. The guide mechanism includes a guide block, a guide tooth plate and a C-shaped clamping plate, and the C-shaped clamping plate is movably sleeved on the outer surface of the traveling cable.

[0003] By creating a guide groove on the inner wall of the elevator shaft and attaching a C-shaped clamp to the outer surface of the traveling cable, the C-shaped clamp moves along the guide groove as the traveling cable moves. This reduces the risk of the traveling cable, which lacks any protective device in traditional devices and is prone to swaying when moving with the car, causing it to collide with other components in the elevator shaft and cause damage.

[0004] Although the technical solution in the prior art can limit the cable using a C-type clamp, the cable will experience severe friction when moving inside the C-type clamp, which will cause serious wear and damage to the cable's surface insulation layer over time. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an anti-sway device for elevator traveling cables, which solves the problem that severe friction occurs when the cable moves inside the C-shaped clamp, leading to severe wear and damage to the cable's surface insulation layer over time.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-sway device for elevator traveling cables, comprising an elevator shaft, a connecting block fixedly connected to the side of the elevator shaft, a limit component fixedly connected to one end of the connecting block, and a monitoring component fixedly connected to the top surface of the limit component.

[0007] The limiting component includes a buckle fixedly connected to one end of the connecting block. The inner sidewall of the buckle is provided with several rotating grooves, and a roller is rotatably connected inside the rotating groove.

[0008] The monitoring component includes a device plate fixedly connected to the top surface of the buckle. The side of the device plate has a large sleeve hole and a small sleeve hole respectively. A supplementary light is fitted inside the small sleeve hole, and an image acquisition structure is fitted inside the large sleeve hole. A remote module is provided on the back of the device plate.

[0009] In one specific embodiment, the rotating grooves are arranged at equal intervals along the horizontal direction on the inner sidewall of the buckle, and the axial direction of each rotating groove is perpendicular to the extension direction of the buckle.

[0010] In one specific embodiment, the outer circumferential surface of the roller is an arc-shaped protrusion, the outer diameter of which matches the outer diameter of the cable.

[0011] In one specific embodiment, the fill lights of the device board are symmetrically distributed on both sides of the image acquisition structure, and the optical axis of the fill lights is parallel to the optical axis of the image acquisition structure.

[0012] In one specific embodiment, the lens of the image acquisition structure is positioned facing the cable inside the latch, and its field of view covers the cable section above the roller.

[0013] In one specific embodiment, the remote module is electrically connected to the image acquisition structure via a cable passing through the device board, and the remote module has a built-in wireless communication unit.

[0014] Compared with the prior art, this utility model provides an anti-sway device for elevator traveling cables, which has the following beneficial effects:

[0015] In the technical solution disclosed in this utility model, the sliding friction of the cable is converted into rolling friction by rollers, which significantly reduces the risk of wear; at the same time, the surface condition of the cable is monitored in real time by an image acquisition structure, and damage early warning is realized by a remote module, thus solving the cable damage problem from the dual dimensions of physical protection and intelligent monitoring.

[0016] The limiting component and monitoring component of this invention provide stable support by fixing the cable to the side of the elevator shaft via a connecting block. The inner wall of the buckle of the limiting component is provided with a groove and a roller, so that the cable forms rolling friction with the roller during movement instead of the sliding friction of the traditional C-shaped clamp. The arc-shaped protrusion on the outer circumference of the roller matches the outer diameter of the cable, which greatly reduces the coefficient of friction and disperses the contact stress, fundamentally solving the defect of cable insulation wear caused by long-term friction in the prior art. At the same time, the equipment board of the monitoring component integrates a supplementary light and an image acquisition structure. The supplementary light is symmetrically distributed on both sides of the image acquisition structure and the optical axis is flat. The system ensures uniform illumination of the cable section above the roller, enabling the image acquisition structure lens to accurately capture the cable surface condition. When damage is detected, the data is transmitted to the remote module via a cable running through the equipment board, and a warning signal is sent in real time by the built-in wireless communication unit, forming a functional breakthrough over traditional anti-sway devices that are limited to positioning but lack monitoring. Finally, the collaborative design of the connecting block limiting component and the monitoring component not only suppresses cable swaying and collisions with other components in the elevator shaft, but also protects the cable body through rolling friction, and achieves active damage protection through intelligent image diagnosis, thus constructing a dual protection mechanism of mechanical anti-sway and digital monitoring.

[0023] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] Figures 1-4 As an embodiment of the present utility model, an anti-sway device for elevator traveling cable includes an elevator shaft 1, a connecting block 2 fixedly connected to the side of the elevator shaft 1, a limit component 3 fixedly connected to one end of the connecting block 2, and a monitoring component 4 fixedly connected to the top surface of the limit component 3.

[0025] The specific problem addressed in this embodiment is to solve the issue of severe friction generated when cables move inside the C-shaped clamp, which over time leads to serious wear and damage to the cable's surface insulation layer. This invention utilizes rollers 32 to convert sliding friction into rolling friction, significantly reducing the risk of wear. Simultaneously, it employs an image acquisition structure 43 to monitor the cable surface condition in real time, combined with a remote module 44 to provide damage warnings, thus solving the cable damage problem from both physical protection and intelligent monitoring perspectives.

[0026] The limiting component 3 includes a buckle 31 fixedly connected to one end of the connecting block 2. The inner side wall of the buckle 31 has several rotating grooves, and a roller 32 is rotatably connected inside the rotating grooves. The monitoring component 4 includes a device plate 41 fixedly connected to the top surface of the buckle 31. The side of the device plate 41 has a large sleeve hole and a small sleeve hole respectively. A supplementary light 42 is sleeved inside the small sleeve hole, and an image acquisition structure 43 is sleeved inside the large sleeve hole. A remote module 44 is provided on the back of the device plate 41. In this specific embodiment, the lens of the image acquisition structure 43 is set towards the cable inside the buckle 31, and its field of view covers the cable section above the roller 32. The connecting block 2 is fixed to the side of the elevator shaft 1 to provide stable support. The inner wall of the buckle 31 of the limiting component 3 is provided with a rotating groove and a roller 32, so that the cable forms rolling friction with the roller 32 when it moves, instead of the sliding friction of the traditional C-shaped plate. The arc-shaped protrusion on the outer circumference of the roller 32 matches the outer diameter of the cable, which greatly reduces the coefficient of friction and disperses the contact stress, fundamentally solving the defect of cable insulation wear caused by long-term friction in the background technology. At the same time, the equipment board 41 of the monitoring component 4 integrates a supplementary light 42 and an image acquisition structure 43 of model DS-2CD3326DW-ISD. The supplementary lights 42 are symmetrically distributed on both sides of the image acquisition structure 43 and the optical axis is parallel. This ensures uniform illumination of the cable section above roller 32, enabling the image acquisition structure 43 lens to accurately capture the cable surface condition. When damage is detected, the data is transmitted through the cable passing through the equipment board 41 to the remote module 44 (model USR-G806), and the built-in wireless communication unit sends a warning signal in real time, forming a functional breakthrough over traditional anti-sway devices that are limited to positioning but lack monitoring. Finally, the collaborative design of the limiting component 3 and monitoring component 4 of the connecting block 2 not only suppresses cable swaying and collisions with other components in the elevator shaft, but also protects the cable body through rolling friction, and achieves active damage protection through intelligent image diagnosis, thus constructing a dual protection mechanism of mechanical anti-sway and digital monitoring.

[0027] In this specific embodiment, the rotating grooves are arranged at equal intervals along the horizontal direction on the inner sidewall of the buckle 31, and the axial direction of each rotating groove is perpendicular to the extension direction of the buckle 31. The rotating groove array with consistent horizontal spacing is opened on the inner sidewall of the buckle 31 by mechanical processing. The axis of the rollers 32 assembled in the rotating grooves is perpendicular to the length direction of the buckle 31, so that when the cable contacts all the rollers 32, the force is uniform and the rolling direction is consistent. This not only prevents the cable from shifting laterally, but also minimizes local friction loss through multi-point uniform rolling.

[0028] In this specific embodiment, the supplementary lights 42 of the device board 41 are symmetrically distributed on both sides of the image acquisition structure 43, and the optical axis of the supplementary lights 42 is parallel to the optical axis of the image acquisition structure 43. Two supplementary lights 42 are symmetrically embedded in the small sleeve holes of the device board 41, and their optical axes are calibrated to be parallel to the optical center axis of the image acquisition structure 43 and on the same horizontal plane. The illumination light path covers the cable section above the roller 32, forming a shadowless and uniform illumination field, so that the image acquisition structure 43 can accurately identify cracks or wear on the cable surface.

[0029] Working principle: The side wall of elevator shaft 1 is fixed by the buckle 31 of the limiting component 3 through the connecting block 2. When the elevator car moves, the cable is pressed and contacts the roller 32 on the inner side wall of the buckle 31. The roller 32 rotates with the cable, which converts the sliding friction between the cable and the buckle 31 into rolling friction. At the same time, the supplementary lights 42 symmetrically arranged on the equipment board 41 of the monitoring component 4 project parallel light onto the cable section above the roller 32. The lens of the image acquisition structure 43 captures the image of the cable surface in the illuminated area. The acquired data is transmitted to the remote module 44 through the cable passing through the equipment board 41. The built-in wireless communication unit sends the cable status signal to the remote terminal to realize the coordinated operation of anti-sway and wear reduction and real-time monitoring.

The power supply is also common knowledge in the field.
