Description

Technical Field

[0001] This application relates to the field of wire rope replacement technology, and in particular to an elevator wire rope replacement device. Background Technology

[0002] Traditional elevator wire rope replacement equipment has a fixed winding diameter, making it difficult to adjust for different specifications of elevator wire ropes. This means that when faced with replacement tasks involving wire ropes of various diameters, it is necessary to frequently change equipment or winding wheel components, which is cumbersome and costly.

[0003] Even if some devices have the function of adjusting the winding diameter, the adjustment method is extremely complicated. It requires the use of special tools to disassemble and assemble multiple parts to change the diameter of the winding wheel, and the adjustment process is difficult to control precisely, making it difficult to meet the needs of flexible adjustment of the winding diameter in different replacement scenarios.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the issue that traditional elevator wire rope replacement equipment has a fixed winding diameter, making it difficult to adjust for different specifications of elevator wire ropes, this application provides an elevator wire rope replacement device. This addresses the problem that when replacing wire ropes of various diameters, frequent replacement of equipment or winding wheel components is necessary, resulting in cumbersome operation and high costs.

[0006] The elevator wire rope replacement device provided in this application adopts the following technical solution:

[0007] An elevator wire rope replacement device includes a frame assembly, which consists of a first frame and a second frame. A replacement turntable is rotatably mounted on the inner wall of the top of the first frame. A screw is movably disposed at the center of the inner wall of the replacement turntable. A matching sliding sleeve is connected to the outer wall of the screw. An adjustment mechanism is provided on the sliding sleeve. The adjustment mechanism includes a support arm distributed on the outer wall of the sliding sleeve, a push rod disposed at one end of the support arm, and a rope winding wheel fixed to the outer wall of the push rod. An adjustable tensioning wheel is installed inside the top of the second frame.

[0008] Preferably, the first frame and the second frame are integrally formed, and positioning plates are welded to the outer walls at both ends of the first frame and the second frame.

[0009] Preferably, a bracket is welded to the top of one back wall of the frame, and a motor is installed inside the bracket. The output end of the motor passes through the inner wall of the bracket and is driven by the replacement turntable.

[0010] Preferably, one end of the screw extends to the outside of the frame and is fixed with a wheel, the sliding sleeve is threadedly adapted to the screw, and a set of connecting edges are fixed at equal intervals on the outer wall of the sliding sleeve, and the support arm is rotatably connected to the push rod and the connecting edges.

[0011] Preferably, the surface of the replacement turntable is provided with a set of movable slots at equal intervals along the circumference, one end of the push rod extends outside the movable slot, and both ends of the push rod are provided with pulleys for rotation.

[0012] Preferably, a threaded rod is connected inside the top end of the second frame, a support spring is provided on the outer wall of the top end of the threaded rod, and both ends of the threaded rod are threadedly connected to matching fasteners. One end of the threaded rod extends into the second frame and is movably connected to a connector.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] This application utilizes a screw-driven sliding sleeve to reciprocate linearly along the outer wall. When the sliding sleeve approaches the changing turntable, the support arm rotates at the connecting edge under pressure, pushing the push rod to slide within the moving groove, causing the pulley to slide along the outer wall of the changing turntable, thereby expanding the winding diameter of the rope sheave; conversely, it shrinks. This design flexibly adapts to elevator wire ropes of different specifications and replacement scenarios, significantly enhancing the equipment's versatility and facilitating winding and unwinding operations during wire rope replacement.

[0015] Meanwhile, by adjusting the fasteners at both ends to adjust the height of the tensioning wheel, and in conjunction with the change disc, the tension of the wire rope is precisely changed, effectively tightening the wire rope. This not only improves the efficiency of wire rope replacement but also ensures that the replaced wire rope is in a suitable tension state, strongly guaranteeing the safety and stability of elevator operation.

[0020] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0021] This application discloses an elevator wire rope replacement device. (Refer to...) Figures 1-2 The system includes a frame assembly, consisting of frame 1 and frame 2, which are integrated into a single unit. Positioning plates 3 are welded to the outer walls at both ends of both frames 1 and 2. Fixing the positioning plates 3 allows for quick and stable installation of frames 1 and 2. A changing turntable 4 is rotatably mounted on the inner wall of the top of frame 1. A bracket 10 is welded to the top of the back wall of frame 1, and a motor 11 is installed inside the bracket 10. The output end of the motor 11 passes through the inner wall of the bracket 10 and drives the changing turntable 4. The motor 11 drives the changing turntable 4 to rotate, enabling rope winding operations.

[0022] like Figure 3 As shown, a screw 17 is movably mounted at the center of the inner wall of the changing turntable 4. A matching sliding sleeve 19 is connected to the outer wall of the screw 17. One end of the screw 17 extends outside the frame 1 and is fixed with a rotating wheel 18. The other end of the screw 17 is rotatably connected to the inner wall of the frame 1. The sliding sleeve 19 is threadedly fitted to the screw 17. By rotating the rotating wheel 18, the screw 17 moves within the changing turntable 4, thereby driving the sliding sleeve 19 to perform linear reciprocating motion along the outer wall.

[0023] In this application, the sliding sleeve 19 is equipped with an adjustment mechanism, which includes a support arm 15 distributed on the outer wall of the sliding sleeve 19, a push rod 13 located at one end of the support arm 15, and a winding wheel 16 fixed to the outer wall of the push rod 13. A set of connecting edges 20 are fixed at equal intervals on the outer wall of the sliding sleeve 19. The support arm 15 is rotatably connected to the push rod 13 and the connecting edges 20. When the sliding sleeve 19 approaches the changing turntable 4, the support arm 15 rotates under pressure on the connecting edges 20, pushing the push rod 13 to slide within the moving groove 12, causing the pulley 14 to slide along the outer wall of the changing turntable 4, thus expanding the winding diameter of the winding wheel 16; conversely, it shrinks. This flexible adjustment method facilitates winding and unwinding operations during wire rope replacement, adapting to different specifications and replacement scenarios of elevator wire ropes, thus enhancing the equipment's versatility.

[0024] In this application, a set of movable grooves 12 are equidistantly provided on the surface of the replacement turntable 4 along the circumference. One end of the push rod 13 extends outside the movable groove 12, and pulleys 14 are rotatably provided on the outer walls of both ends of the push rod 13. As the push rod 13 moves, the pulleys 14 will contact the surface of the replacement turntable 4, thereby assisting the sliding and improving the adjustment speed.

[0025] Furthermore, an adjustable tensioning wheel 7 is installed inside the top of the second frame 2, and a threaded rod 5 is connected inside the top of the second frame 2. A support spring 8 is provided on the outer wall of the top of the threaded rod 5. Both ends of the threaded rod 5 are threadedly connected to matching fasteners 9. One end of the threaded rod 5 extends into the second frame 2 and is movably connected to a connecting piece 6. By adjusting the fasteners 9 at both ends, the height of the tensioning wheel 7 can be adjusted. In conjunction with the replacement turntable 4, the tension of the wire rope can be effectively changed to achieve the purpose of tensioning the wire rope. This not only improves the efficiency of wire rope replacement but also ensures that the replaced wire rope is in a suitable tension state, ensuring the safety and stability of elevator operation.

[0026] The implementation principle of the elevator wire rope replacement device in this application embodiment is as follows:

[0027] In use, the installation of frame 1 and frame 2 is completed by fixing the positioning plate 3. Then, one end of the elevator wire rope to be replaced can be wound around the outside of the winding wheel 16. Depending on the needs, rotating the wheel 18 will drive the screw 17 to move within the replacement turntable 4, which will drive the sliding sleeve 19 to reciprocate linearly along its outer wall. As the sliding sleeve 19 gets closer to the replacement turntable 4, the support arm 15 is subjected to compressive force, which, combined with the connecting edge 20, will rotate and push the push rod 13 to slide outward within the moving groove 12. At this time, the pulley 14 slides along the outer wall of the replacement turntable 4, reducing resistance. This operation can increase the winding diameter of the winding wheel 16; conversely, it reduces the winding diameter of the elevator wire rope, facilitating the winding and unwinding of the wire rope during replacement.

[0028] When the motor 11 is working, it drives the entire changing turntable 4 to rotate for winding and unwinding, and makes one end of the wire rope wrapped around the outside of the tensioning wheel 7. By adjusting the fasteners 9 at both ends, the height of the tensioning wheel 7 can be adjusted. Through the cooperation of the tensioning wheel 7 and the changing turntable 4, the tension of the wire rope changes, thereby achieving the purpose of tensioning the wire rope.
