Description

Technical Field

[0001] This utility model relates to the field of elevator installation technology, and in particular to a wire rope releasing device for elevator installation. Background Technology

[0002] In elevator installation, the lowering of the wire rope is a crucial step, as its efficiency and safety directly affect the overall construction progress and operational safety. In traditional elevator installation, the lowering of the wire rope often relies on manual operation: operators need to manually drag the wire rope or use simple supports in conjunction with manual rotation of the drum to lower the rope. The prior art patent document CN223254662U discloses a wire rope unloading device for elevator installation, including a fixed plate with a through hole and a guide device inside the through hole. Two vertical plates, a first vertical plate and a second vertical plate, are symmetrically arranged on the upper surface of the fixed plate. A driving device is located between the first and second vertical plates. An oiling device is fixed on the inner wall of the first and second vertical plates, and an oil spraying device is located on the outer wall of the first vertical plate. Through the operation of a delivery pump, lubricating fluid is delivered to a distribution pipe, then to oil spraying pipes one and two. The lubricating oil is then sprayed onto an oiling roller through a nozzle, and finally brushed onto the wire rope through an oiling brush. This achieves maintenance of the wire rope, ultimately reducing friction during operation by oiling the surface of the wire rope during its lifting and lowering process.

[0003] The aforementioned patent specification mentions "a wire rope unloading device for elevator installation. During operation, the device first drives the rotation of a drive motor, which in turn drives the rotation of the unloading rollers, thereby moving the wire rope. Then, the movement of a moving cylinder drives the movement of moving plates one and two, which in turn moves the guide wheel, guiding the wire rope. A delivery pump then delivers lubricating fluid to a distribution pipe, which in turn delivers it to oil spray pipes one and two. The lubricating oil is then sprayed onto an oiling roller through a nozzle, and finally brushed onto the wire rope through an oiling brush, thus maintaining and protecting the wire rope. Ultimately, this achieves surface oiling maintenance of the wire rope during its lifting and lowering process, thereby reducing friction during operation." While this method ensures rapid unloading, it fails to guarantee stability, resulting in poor stability. Therefore, this paper proposes a wire rope unloading device for elevator installation to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a wire rope releasing device for elevator installation, which solves the problem of low efficiency in some wire rope releasing devices.

[0005] To achieve the above objectives, this utility model provides a wire rope releasing device for elevator installation, including a support frame. A rope releasing mechanism is fixedly connected to the outside of the support frame, and a protective mechanism is rotatably connected to the outside of the support frame. The rope releasing mechanism includes a drive assembly for driving. A pulley is fixedly connected to the outside of the drive assembly, and the drive assembly is rotatably connected to the inside of the support frame. A rotating track is sleeved on the outside of the pulley, and a pulley is rotatably connected to the inner side of the rotating track, i.e., the end away from the pulley. A connecting column is fixedly connected to the inside of the pulley, and a coiling frame is fixedly connected to the outside of the connecting column. A wire rope is slidably connected to the outside of the coiling frame.

[0006] The protective mechanism includes a rotating block, with a support column rotatably connected inside the rotating block, and the support column being fixedly connected to the inside of the support frame.

[0007] The pulley is rotatably connected to the outside of the support frame, and the track is rotatably connected to the outside of the support frame.

[0008] The outer part of the curling frame is rotatably connected to the inner side of the support frame, and the outer part of the second connecting column is rotatably connected to the inside of the support frame.

[0009] The drive assembly includes a motor, the drive end of which is fixedly connected to a connecting column, and the motor is externally fixedly connected to the outside of the support frame.

[0010] The external part of the first connecting column is rotatably connected to the inside of the support frame, and the external part of the first connecting column is fixedly connected to the inside of the first pulley.

[0011] The support column is fixedly connected to the outside of a wear-resistant layer, and a support layer is fixedly connected to the inside of the wear-resistant layer.

[0012] The inner side of the support layer is fixedly connected to a protective layer, and the outer side of the support frame is fixedly connected to a storage box.

[0013] This utility model discloses a wire rope lowering device for elevator installation. When the wire rope needs to be lowered, the motor starts running, directly driving the first connecting column to rotate. After the first connecting column rotates, it synchronously drives the first belt pulley connected to it to rotate. The first belt pulley further drives the rotating track to rotate in a cycle, and the second belt pulley drives the second connecting column to rotate, which in turn causes the coiling frame assembled with the second connecting column to rotate. During the rotation of the coiling frame, the wire rope originally wrapped on it is gradually released, meeting the basic requirements for lowering the wire rope during elevator installation. The device accelerates the lowering speed of the wire rope and improves the progress of the project through an automated structure driven by a motor and linked with multiple components. Manual rope lowering is prone to uneven force control, which can cause the wire rope to slip and become entangled, posing a safety hazard. This device reduces damage to the wire rope, ensures construction safety and material integrity, improves the overall durability of the equipment, and reduces maintenance costs.

[0014] This utility model discloses a wire rope release device for elevator installation. When it is necessary to replace wire ropes of different specifications, manually rotating the wear-resistant layer will cause the rotating block to rotate around the support column, realizing the rapid opening and closing of the protective mechanism. The two ends of the support column are fixed to the support frame. The protective layer adheres to the support column to prevent corrosion and scratches. The support layer provides support for the wear-resistant layer. The wear-resistant layer contacts the inner wall of the rotating block to ensure smooth opening and closing. The storage box outside the support frame improves the overall progress of elevator installation. The cooperation between the support layer and the wear-resistant layer reduces equipment maintenance costs, temporarily stores the ends of excess wire rope to prevent them from swinging and causing safety hazards, creates a safe and clean working environment for operators, reduces the possibility of accidental bumps during wire rope replacement, and ensures personnel safety.

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] The embodiment of this application is as follows: Please see Figures 1 to 3 A wire rope releasing device for elevator installation includes a support frame 1 to ensure that all components maintain a stable relative position during operation, providing a safe operating platform for operators. A rope releasing mechanism 2 is fixedly connected to the outside of the support frame 1, and a protective mechanism 3 is rotatably connected to the outside of the support frame 1. The rope releasing mechanism 2 includes a drive assembly 21 for driving, and a pulley 22 is fixedly connected to the outside of the drive assembly 21. The pulley 22 has a disc-shaped structure to prevent tilting during rotation. Power is transmitted through the pulley 22. The drive assembly 21 is externally rotatably connected to the inside of the support frame 1. A rotating track 23 is fitted on the outside of the pulley 1 22 to transmit the power of the pulley 1 22 to multiple pulleys 24, ensuring the synchronous rotation of each pulley 24. The inner side of the rotating track 23, i.e. the end away from the pulley 1 22, is rotatably connected to the pulley 24, converting the circulating power transmitted by the rotating track 23 into the rotational power of the connecting column 25, providing a rotational foundation for the coiling frame 26. The connecting column 25 is fixedly connected inside the pulley 24. A coiling frame 26 is fixedly connected to the outside of the connecting column 25. The coiling frame 26 rotates to achieve the winding, storage, and orderly lowering of the wire rope 27. The wire rope 27 is slidably connected to the outside of the coiling frame 26. The pulley 22 is rotatably connected to the outside of the support frame 1. The rotating track 23 is rotatably connected to the outside of the support frame 1. The coiling frame 26 is rotatably connected to the inside of the support frame 1. The connecting column 25 is rotatably connected to the inside of the support frame 1. The drive assembly 21 includes a motor 211. The motor 211 provides continuous and controllable rotational power to the equipment, enabling flexible adjustment during the rope release process. The drive end of the motor 211 is fixedly connected to the connecting column 212, which is responsible for transmitting the rotational power output by the motor 211 to the pulley 22. At the same time, it serves as a support component to ensure the stable operation of the pulley 22. The motor 211 is externally fixedly connected to the outside of the support frame 1, and the connecting column 212 is externally rotatably connected to the inside of the support frame 1. The connecting column 212 is externally fixedly connected to the inside of the pulley 22.

[0023] like Figures 2 to 4 As shown, the protective mechanism 3 includes a rotating block 31, which facilitates equipment maintenance and replacement of the wire rope 27. When closed, it forms a protective barrier. A support column 32 is rotatably connected inside the rotating block 31, providing a fulcrum for rotation. The multi-layered covering structure enhances its durability and protective effect. The support column 32 is externally fixedly connected to the inside of the support frame 1. A wear-resistant layer 35 is also fixedly connected to the outside of the support column 32, contacting the rotating block 31 to reduce friction and wear during rotation, ensuring smooth opening and closing of the protective mechanism 3. A support layer 34 is fixedly connected to the inner side of the wear-resistant layer 35, located between the protective layer 33 and the wear-resistant layer 35, providing support for the wear-resistant layer 35. A protective layer 33 is fixedly connected to the inner side of the support layer 34, adhering to the surface of the support column 32, providing corrosion and scratch protection, and protecting the main structure of the support column 32. A storage box 4 is fixedly connected to the outside of the support frame 1.

[0024] Working principle: When it is necessary to lower the wire rope 27, the operation of the motor 211 drives the rotation of the connecting column 212, which in turn drives the rotation of the pulley 22 and the rotating track 23, which in turn drives the rotation of the pulley 24, which in turn drives the rotation of the connecting column 25 and the coiling frame 26, which in turn drives the rotation of the wire rope 27, thereby achieving the effect of quickly lowering the wire rope 27 and quickly releasing the rope.

[0025] When it is necessary to replace the steel wire rope 27 of different specifications, the wear-resistant layer 35 is manually rotated, which drives the rotating block 31 to rotate on 32, thereby achieving a quick opening and closing effect. The protective layer 33 is attached to the surface of the support column to prevent corrosion and scratches. The support layer 34 provides support for the wear-resistant layer 35. The wear-resistant layer 35 is in contact with the inner wall of the rotating block 31 to ensure smooth opening and closing. The storage box 4 fixed on the outside of the support frame 1 can store elevator installation tools and accessories, or temporarily store the ends of excess steel wire rope 27, improving construction convenience and site cleanliness.

[0026] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
