[0002] An elevator is a permanent transportation device that serves several specific floors within a building. Its car moves along at least two rigid tracks that are perpendicular to the horizontal plane or have an angle of inclination of less than 15 degrees to the vertical. Elevators require a large number of cables to connect, which, along with the transmission mechanism, drive the elevator to operate normally. During use, the cables move up and down with the elevator car. However, in actual use, the traveling cables are usually flat cables. The purpose of this is to keep multiple cables together and prevent them from getting tangled. But during the elevator's up and down movement, the cables will sway, causing them to rub against the fixed cables at the bottom of the car. This makes the cables prone to damage and breakage, affecting subsequent use. Utility Model Content

[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0028] like Figure 1-5 The image shows an elevator cable anti-sway device according to this embodiment. This anti-sway device is fixed to the elevator car to prevent cable swaying during car movement. The anti-sway device includes a fixing frame 1, a cable guide unit, and a cable wiping assembly. The fixing frame 1 is fixedly installed on one side of the car bottom. Several third connecting seats 8 are fixed to the fixing frame 1. Each third connecting seat 8 has mounting holes. Positioning bolts 81 are movably inserted into these mounting holes. The positioning bolts 81 are threaded into pre-drilled holes at the bottom of the car to lock the third connecting seats 8 and the fixing frame 1 securely to the car.

[0029] The aforementioned sets of cable guiding units are arranged at intervals on the fixed frame 1. In this embodiment, four sets of cable guiding units are arranged. The left and right directions refer to the length or width of the car, depending on the specific location of the cable. Each cable guiding unit includes a roller 2, a base plate 3, and an adjustment assembly. The roller 2 is a cylindrical structure, with both ends mounted on the fixed frame 1 via bearings, allowing the roller 2 to rotate around its central axis. In a specific arrangement, the roller 2 extends in the front-to-back direction, giving it a central axis extending in that direction. The base plate 3 is located below the roller 2, having a width extending left and right and a length extending front-to-back. A vertical gap is formed between the base plate 3 and the roller 2. The size of this vertical gap is adapted to the thickness of the cable, allowing the cable to pass through it.

[0030] The aforementioned adjustment component is installed between the fixed frame 1 and the base plate 3 to adjust the vertical position of the base plate 3, thereby adjusting the size of the vertical gap. By adjusting the component, the thickness of the cable is made to match the vertical gap, thus limiting the cable between the base plate 3 and the roller 2 and preventing the cable from shaking.

[0031] In the specific structural design, the aforementioned adjustment components include a first component 4 and a second component 5. The first component 4 includes a first connecting seat 42, a first fixing block 7341, and an adjusting rod 43. One of the first connecting seat 42 and the first fixing block 7341 is fixed to the fixing frame 1, and the other is fixed to the base plate 3. The adjusting rod 43 is a threaded rod that extends vertically. The adjusting rod 43 is threadedly connected to the first connecting seat 42, and one end of the adjusting rod 43 is rotatably connected to the first fixing block 7341. By rotating the adjusting rod 43 in both directions, the base plate 3 can be driven closer to or further away from the roller body 2, thereby adjusting the vertical gap. The aforementioned second component 5 includes a second connecting seat 52, a second fixing block 7351, and a guide rod 53. One of the second connecting seat 52 and the second fixing block 7351 is fixed to the fixing frame 1, and the other is fixed to the base plate 3. The guide rod 53 extends vertically and is fixed to the second fixing block 7351, and moves vertically through the second connecting seat 52. The guide rod 53 serves a guiding function to improve the stability of the vertical movement of the base plate 3. A handle is installed on the adjusting rod 43, allowing the adjusting rod 43 to be rotated by gripping the handle.

[0032] The aforementioned cable wiping assembly is arranged in a set, installed between two adjacent sets of cable guiding units. The cable wiping assembly includes a connecting component 7, a frame 6, and a brush strip 61. The connecting component 7 is fixed to the fixing frame 1. The frame 6 is fixed to the connecting component. Above. Two brush strips 61 are arranged vertically and spaced apart on the frame 6. A cable insertion channel is formed between the two brush strips 61. The vertical height of this cable insertion channel is adapted to the thickness of the cable. The cable can be inserted into the aforementioned vertical gap and the cable insertion channel in a left-right direction. The brush strips 61 have a wiping surface facing the cable insertion channel and in contact with the end face of the cable. The brush strips 61 can be made of sponge or a board with bristles. When the cable is inserted into the cable insertion channel, the wiping surface contacts the upper and lower surfaces of the cable to wipe the cable.

[0033] The aforementioned frame 6 is a concave frame structure with an opening on one side that connects to the aforementioned cable insertion channel. Cables can enter and exit the cable tray insertion channel through this opening.

[0034] The aforementioned base 71 has a front-to-back extending insertion groove 711 machined on it. This insertion groove 711 extends vertically through the base 71. One end of the insertion groove 711 is open. Several positioning grooves 712 are machined on the top surface of the base 71. The base 71 is fixed to the fixing frame 1, and the aforementioned frame 6 is arranged below the base 71. A connecting block 72 is connected to the top of the frame 6 and is movably inserted into the insertion groove 711. The connecting block 72 can be moved out of the base 71 through the open end of the insertion groove 711. The aforementioned fixing block 73 is arranged above the base 71 and connected to the connecting block 72. Positioning protrusions 721 are machined on the fixing block 73 corresponding to the positioning grooves 712. The aforementioned positioning protrusions 721 and positioning grooves 712 are vertically inserted and engaged. By lifting the fixing block 73 upwards, the positioning protrusion 721 can be disengaged from the positioning groove 712, and the connecting block 72 can be moved out of one end of the insertion groove 711, thereby allowing the frame 6 to be removed from the fixing frame 1.

[0035] During assembly, the fixing frame 1 is placed on one side of the bottom of the car and connected to the pre-drilled holes in the bottom of the car using positioning bolts 81 to lock the third connecting seat 8 and the fixing frame 1 onto the car. The cables are inserted sequentially between the rollers 2 and the base plate 3 of each set of cable guide units. The adjusting rod 43 is rotated to adjust the vertical position of the base plate 3, thus limiting the cable position between the rollers 2 and the base plate 3. The opening on the side of the frame 6 is oriented towards the cable, and the frame 6 is moved so that the connecting block 72 is inserted into the insertion slot 711 on the seat 71. Simultaneously, the cable enters the cable insertion channel between the two brush strips 61 through the opening on the side of the frame 6. Finally, the positioning protrusion 721 on the fixing block 73 is inserted into the positioning groove 712 for fixation. This combination of methods allows for adjustment of the vertical gap via the adjusting components, thus accommodating the insertion requirements of cables of different thicknesses. When the elevator car moves up and down, the cable contacts the auxiliary rollers to guide the cable, preventing it from swaying and also preventing cable wear. The brush strip 61 comes into contact with the cable. When the cable moves, the brush strip 61 can wipe the surface of the cable to ensure stable and smooth cable movement, prevent the cable from getting stuck, effectively meet the usage requirements of elevator cables, and is highly practical.
