However, in actual use, due to various factors such as unreasonable design of the number of layers of the wire rope, insufficient tension, and high elevator speed, the traction wire rope often twists. Twisting not only affects the normal operation of the elevator, but also shortens the service life of the wire rope, and may even cause safety accidents. Therefore, this utility model proposes an anti-twisting elevator traction wire rope. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example

[0020] Please see Figures 1 to 3 This is an embodiment of the present invention, which provides a technical solution: an anti-torsion elevator traction steel wire rope, comprising...

[0021] The main body 1 of the wire rope passes through the crossbeam 7 and is wound around the traction sheave 8; the support 2 is fixed to the bottom surface of the crossbeam 7; the transverse base column 3 passes through the surface of the support 2; the side support block 4 is movably installed at the front end of the transverse base column 3; and the tensioning wheel 5 is rotatably installed at the end of the side support block 4 and in contact with the main body 1 of the wire rope. The function of the tensioning wheel 5 is to tension the main body 1 of the wire rope to a certain extent, maintain the tightness of the main body 1 of the wire rope during operation, reduce the possibility of twisting, and play a role in preventing twisting.

[0022] The main body 1 of the wire rope includes an intermediate strand 11, an outer strand 12, and an outer strand 2 13. The intermediate strand 11 is located inside the outer strand 12 and the outer strand 2 13. The cross-sections of the intermediate strand 11, the outer strand 12, and the outer strand 2 13 are all hexagonal. The fact that the intermediate strand 11, the outer strand 12, and the outer strand 2 13 are all set with hexagonal cross-sections allows the main body 1 of the wire rope to be tightly twisted, thereby enhancing its anti-rotation performance.

[0023] In this embodiment, preferably, a movable groove 31 is provided in the transverse base column 3, and the rear end of the side support block 4 is movably installed in the movable groove 31. Two springs 32 that abut against the side support block 4 are also installed in the movable groove 31. Under the pushing of the springs 32, the tensioning wheel 5 at the front end of the side support block 4 can keep in constant contact with the wire rope body 1, so as to ensure the tensioning effect on the wire rope body 1.

[0024] In this embodiment, preferably, a guide block 41 is fixed on both sides of the inner end of the side support block 4, and a guide groove 33 is provided on both sides of the inner wall of the movable groove 31. The guide block 41 slides in the guide groove 33, so that the inner end of the side support block 4 will not slide directly out of the movable groove 31, thus ensuring the stability of the movable connection between the transverse base column 3 and the side support block 4.

[0025] It also includes an adjustment structure 6, which is located between the support 2 and the transverse base column 3. The adjustment structure 6 includes a threaded column 61 welded and fixed to the bottom surface of the support 2, a pressure block 63 and a fastening nut 62 sleeved on the surface of the threaded column 61, a limiting insert 64 welded and fixed to the top left end of the pressure block 63, and multiple limiting slots 65 corresponding to the limiting inserts 64 on the bottom surface of the transverse base column 3. The top of the limiting insert 64 is inserted into one of the limiting slots 65 to stably limit the transverse base column 3. The position of the transverse base column 3 can also be adjusted laterally, thereby adjusting the tension wheel 5. To adjust the tension of the wire rope body 1, simply turn the fastening nut 62 counterclockwise, causing the pressure block 63 and the limiting block 64 to move downwards until the top of the limiting block 64 moves out of the limiting slot 65. This will remove the limiting effect on the transverse base column 3, allowing the transverse base column 3 to be moved laterally. This will adjust the tension of the tensioning wheel 5 on the wire rope body 1. Once the appropriate tension is achieved, push the pressure block 63 upwards again and tighten the fastening nut 62 clockwise, allowing the top of the limiting block 64 to be inserted into the limiting slot 65 in another position. This will again limit the transverse base column 3, completing the adjustment of the tension of the tensioning wheel 5.

[0026] In this embodiment, preferably, the fastening nut 62 and the threaded post 61 are threadedly connected, and the surface of the pressure block 63 is provided with a sleeve hole corresponding to the threaded post 61.

[0027] In this embodiment, preferably, the surface of the tensioning wheel 5 is also provided with a guide rope groove 51 corresponding to the wire rope body 1, so that when the wire rope body 1 passes through the tensioning wheel 5, it can be further guided and limited by the guide rope groove 51, thereby further achieving the anti-torsion effect.

[0028] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
