[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] The present invention provides: an elevator hanger with an anti-slip structure, such as Figure 1-5 As shown, it includes a transverse beam 1, a longitudinal beam 2, a pulley 3, a side connecting plate 4 and a steel rope 6. Two groups of side connecting plates 4 are provided, and the pulley 3 is rotatably set between the two groups of side connecting plates 4; a rotating column 12 is provided on both sides of the pulley 3, and the pulley 3 is rotatably set between the two groups of connecting frames 11 through the rotating column 12, and a stabilizing frame 10 is provided between the two groups of side connecting plates 4 to ensure the stability of the two groups of side connecting plates 4 after other components are installed. The transverse beam 1 and the longitudinal beam 2 are made of high-strength steel. The transverse beam 1 and the longitudinal beam 2 are fixed to each other by welding or bolting to form a stable rectangular frame structure, ensuring that the transverse beam 1 and the longitudinal beam 2 are connected to form the main frame of the hanger, thereby ensuring that the hanger frame has good strength and rigidity, and the transverse beam 1 and the longitudinal beam 2 are provided with multiple mounting holes for connecting with other components, and when other equipment is connected to the surface of the transverse beam 1 and the longitudinal beam 2, the transverse beam 1 and the longitudinal beam 2 are set inside the elevator shaft by bolting.

[0032] Preferably, the upper surfaces of the two groups of side connecting plates 4 are provided with anti-falling components for preventing the wire rope 6 from falling off the outer arc surface of the pulley 3; the anti-falling components include a limit frame 7, a limit frame 8 and an adjustment module, the limit frame 7 is arranged above the pulley 3, and two groups of limit frames 8 are provided, and the two groups of limit frames 8 are arranged on both sides of the limit frame 7 through extension blocks, and the inner sides of the limit frame 7 and the limit frame 8 are provided with a rope pressing limit module for limiting the wire rope 6. By arranging the limit frame 7 and the limit frame 8 on the outer arc surface of the two groups of pulleys 3, the wire ropes 6 on the outer arc surface of the two groups of pulleys 3 are limited by the limit frame 7 and the limit frame 8, so as to prevent the wire rope 6 from falling out of the rope groove on the outer arc surface of the pulley 3 due to vibration, load change or accidental impact.

[0033] It is worth noting that the adjustment module includes an adjustment frame 5, a threaded rod 13, a turntable 16 and a connecting column 17. The adjustment frame 5 is bolted to the upper surface of the two sets of side connecting plates 4, and the connecting column 17 is fixedly set at the bottom end of the threaded rod 13. The threaded rod 13 is threadedly connected to the adjustment frame 5, and the threaded rod 13 is rotatably connected to the limit frame 7 through the connecting column 17. The top of the threaded rod 13 passes through the adjustment frame 5, and the turntable 16 is fixedly set at the top of the threaded rod 13. By bolting the adjustment frame 5 to the surface of the side connecting plates 4 on both sides, and then the limit frame 7 is connected through the threaded rod 13 and the connecting column 17 It is arranged on the inner side of the adjusting frame 5. When the threaded rod 13 and the adjusting frame 5 are driven to rotate by the turntable 16, the threaded rod 13 will produce a vertical displacement relative to the adjusting frame 5. At this time, the threaded rod 13 drives the limit frame 7 to move up and down through the connecting column 17. The surface of the turntable 16 is provided with anti-slip grooves or scale marks, which is convenient for the installer to accurately control the distance between the pressure plate and the pulley through the torque wrench, ensuring the limiting accuracy of wire ropes with different diameters, thereby adjusting the distance between the limit frame 7 and the limit frame 8 and the wire rope 6, and thus being suitable for wire ropes 6 with different diameters.

[0034] Furthermore, the pressure rope limiting module includes a pressure plate 14, a compression spring 15 and a moving block 20. One end of the compression spring 15 is fixedly arranged on the upper surface of the pressure plate 14, and the other end of the compression spring 15 is connected to the corresponding limit frame 7 and the limit frame 8. The moving block 20 is fixedly arranged on both sides of the pressure plate 14, and the lower surface of the pressure plate 14 is provided with a clamping groove 21 corresponding to the wire rope 6; the moving block 20 is set as a convex block, and the inner sides of the limit frame 7 and the limit frame 8 are provided with a moving groove 18 corresponding to the limit frame 7. The pressure plate 14 is connected to the inner surface of the limit frame 7 and the limit frame 8 by the compression spring 15, and then the stability of the pressure plate 14 during the up and down movement is ensured by the moving block 20 to avoid the pressure plate 14 from moving up and down. When the elevator is started and stopped, the wire rope 6 is offset, thereby ensuring the stability of the wire rope 6 after it is clamped into the clamping groove 21. The pressure plate 14 on the inside applies downward pressure to the wire rope 6 through the clamping groove 21 under the action of the compression spring 15, offsetting the upward movement trend of the wire rope caused by the start and stop of the elevator, thereby further preventing the wire rope 6 from escaping from the rope groove on the outer arc surface of the pulley 3 due to vibration, load changes or accidental impact. The elastic deformation characteristics of the compression spring 15 can adapt to the slight vibration and wear of the wire rope during operation, avoiding stress concentration or wire rope damage caused by rigid limitation, and adding lubricant to the inside of the clamping groove 21 during use to ensure the lubrication of the wire rope 6 during the movement of the clamping groove 21.

[0035] Furthermore, two groups of connecting frames 11 are symmetrically bolted to the upper surfaces of the two groups of side connecting plates 4, and the opposite sides of the two groups of connecting frames 11 are bolted to the side plates 22. The two sides of the limit frame 8 are bolted to the outer sides of the two groups of side plates 22, and adjustment slots 19 are provided on both sides of the limit frame 8; the opposite sides of the two groups of connecting frames 11 are bolted to the side limit frames 9, and another group of adjustment slots 19 are provided on both sides of the side limit frames 9. The bolts on both sides of the side limit frames 9 pass through the corresponding adjustment slots 19 and are bolted to the sides of the connecting frames 11, and the bolts on the sides of the side limit frames 9 are completely screwed into the inside of the connecting frames 11, thereby fixing the position of the side limit frames 9 by the bolts , thereby facilitating the adjustment of the position of the side limit frame 9 while avoiding displacement of the side limit frame 9 when limiting, and the side limit frame 9 does not contact the wire rope 6, thereby ensuring that the wire rope 6 can operate normally, and the wire rope 6 is located inside the limit frame 8 and the side limit frame 9, and the limit frames 8 on both sides are bolted to the side of the side plate 22 through the adjustment groove 19, and the bolts on the side of the limit frame 8 initially penetrate the adjustment groove 19, so that when the limit frame 7 moves up and down, the limit frame 8 is driven to move synchronously, and the limit frame 7 is limited by the bolts and the adjustment groove 19 to avoid rotation when the limit frame 7 moves up and down.

[0036] Accordingly, in combination with the above solutions, the present invention further provides a hanger installation method, including any one of the elevator hangers with an anti-slip structure, comprising the following steps:

[0037] S1: Assemble the transverse beam 1 and the longitudinal beam 2 into the main frame of the hanger by bolting or welding, and symmetrically fix the two sets of side connecting plates 4 to the designated positions of the longitudinal beam 2 to ensure that the two are vertically connected and the structure is stable, thereby ensuring the stability of other components after installation;

[0038] S2: Rotate the pulley 3 between the two sets of connecting frames 11 through the rotating column 12, and then bolt the connecting frames 11 to the upper surface of the corresponding side connecting plates 4 to ensure that the pulley 3 can rotate freely and the axis is perpendicular to the side connecting plates 4, thereby ensuring the stability of the pulley 3 during rotation;

[0039] S3: One end of the compression spring 15 is fixed on the upper surface of the pressure plate 14, and the other end is connected to the inner top surface of the limit frame 7 and the limit frame 8. Convex moving blocks 20 are installed on both sides of the pressure plate 14, and the moving blocks 20 are embedded in the moving grooves 18 inside the limit frame 7 and the limit frame 8. The moving blocks 20 are inserted into the moving grooves 18 to ensure that the pressure plate 14 will not deviate when moving up and down. In this way, the pressure plate 14 is ensured to dynamically limit the steel wire rope 6 while improving the stability of the pressure plate 14 when working;

[0040] S4: Connect the adjustment frame 5 to the limit frame 7 through the threaded rod 13, then bolt the adjustment frame 5 to the upper surface of the two sets of side connecting plates 4, and bolt the limit frame 8 and the side limit frame 9 to the side of the connecting frame 11, and bolt the connecting frame 11 to the surface of the side connecting plate 4, so that the limit frame 8 and the side limit frame 9 are connected to the side connecting plate 4, which facilitates the adjustment of the limit frame 8 and the side limit frame 9. The limit frame 7 is connected to the adjustment frame 5, which facilitates the height adjustment of the limit frame 7;

[0041] S5: The steel wire rope 6 is passed around the outer arc surface of the pulley 3 and sequentially passed through the clamping groove 21 below each group of pressure plates 14, thereby ensuring that the steel wire rope 6 is located inside all the pressure rope limiting modules;

[0042] S6: Turn the turntable 16, and adjust the height of the limit frame 7 by raising and lowering the threaded rod 13, so that the distance between the pressure plate 14 and the outer arc surface of the pulley 3 is slightly smaller than the diameter of the wire rope 6, and the elastic force of the compression spring 15 is used to achieve dynamic compression of the wire rope, ensuring that the wire rope is limited by the clamping groove 21 on both sides of the pulley without the risk of loosening or deviation, thereby improving the overall applicability of the device.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
