Description

Technical Field

[0001] The present application relates to the technical field of a rope-adjusting mechanism for a window cleaning machine, and in particular to a rope-adjusting mechanism for a window cleaning machine. Background Art

[0002] Window cleaning machines are outdoor high-altitude manned equipment. They are permanent special equipment for cleaning and maintenance of exterior wall facades and skylight roofs of high-rise buildings. Different types of window cleaning machines need to be designed according to the building's height, facade and roof structure, load-bearing capacity, and effective space for equipment movement. Safety, economy, and practicality must be taken into consideration, as well as the fact that the installed window cleaning machine must be coordinated with the building and not affect the building's appearance. Therefore, the selection of window cleaning machines is closely related to architectural design and construction.

[0003] When the existing window cleaning machine is in use, the pulley is usually rotated to drive the steel wire rope to be retracted and released, and then the steel wire rope is retracted and released to drive the connected hanging box platform to move up and down on the facade of the building's outer wall. The lifting and moving of the hanging box platform makes it convenient for workers to stand on the hanging box platform to clean the glass windows and other structures on the facade of the building's outer wall;

[0004] However, when the above method is used for window cleaning, the platform is often only able to move straight up and down due to its own weight when the rope is used to drive the platform to move up and down, so it can only be used for some buildings with flat and vertical facades. For some buildings with facades that are inclined from top to bottom, the vertical lifting and moving of the platform causes the platform to be far away from the inclined facades, which makes it difficult for the workers on the platform to clean the windows on the inclined facades due to the long distance, which has certain limitations. Therefore, those skilled in the art provide a rope-following mechanism for a window cleaning machine to solve the problems raised in the above background technology. Utility Model Content

[0025] The rope following assembly 4 includes a mounting frame 401, a first limiting pulley 402 and an angle adjustment unit 5. One end of the mounting frame 401 is mounted on the side wall of the inclined facade wall 1 through an insertion assembly 7. The first limiting pulley 402 is rotatably connected to the middle of the other end of the mounting frame 401. The angle adjustment unit 5 is mounted on the side wall of the mounting frame 401.

[0026] The angle adjustment unit 5 includes two second servo motors 501, two rotating plates 502 and a second limiting pulley 503. The two second servo motors 501 are symmetrically fixedly connected to the side walls of the mounting frame 401. One end of the two rotating plates 502 is respectively fixedly connected to the output ends of the two second servo motors 501. Both ends of the second limiting pulley 503 are installed on the other ends of the two rotating plates 502 through the telescopic unit 6.

[0027] The telescopic unit 6 includes two telescopic chutes 601, two hydraulic cylinders 602 and two telescopic plates 603. The two telescopic chutes 601 are respectively opened on the inner side of the other end of the two rotating plates 502, the two hydraulic cylinders 602 are respectively fixedly connected to one end of the two telescopic chutes 601, the two telescopic plates 603 are respectively slidably connected to the side walls of the two telescopic chutes 601, and the output ends of the two hydraulic cylinders 602 are respectively fixedly connected to one end of the two telescopic plates 603, and the second limiting pulley 503 is rotatably connected between the other ends of the two telescopic plates 603.

[0028] The window cleaning assembly 2 includes a construction platform 201 and a driving unit 3. The driving unit 3 is installed on the top of the inclined facade wall 1. The top of the construction platform 201 is installed on one end of the driving unit 3.

[0029] The driving unit 3 includes two support frames 301, two fixed blocks 302, a rope roller 303, a first servo motor 304 and a steel wire rope 305. The bottoms of the two support frames 301 are symmetrically fixedly connected to the top of the inclined facade wall 1, and the two ends of the rope roller 303 are fixedly connected to the tops of the two support frames 301 through two fixed blocks 302. The first servo motor 304 is fixedly connected to the side wall of one of the fixed blocks 302, and the output end of the first servo motor 304 rotates through the side wall of one of the fixed blocks 302 and is fixedly connected to one end of the rope roller 303. The top of the construction platform 201 is wound and connected with the rope roller 303 through the steel wire rope 305.

[0030] In this embodiment, the support frame 301 and the fixed block 302 are provided to support and fix the rope, and then the first servo motor 304 is provided to start and provide a force to drive the rope roller 303 to rotate between the two fixed blocks 302. The rope roller 303 rotates to reel in or release the steel wire rope 305 wound thereon, and the steel wire rope 305 is reeled in or released to drive the construction platform 201 connected thereto to move upward or downward. The lifting and moving of the construction platform 201 facilitates the workers to clean the windows on the facade of the building.

[0031] Furthermore, when the building facade is an inclined facade, the steel wire rope 305 is connected to the top of the construction platform 201 by passing it between the first limiting pulley 402 and the second limiting pulley 503. At this time, the second servo motor 501 supported and fixed by the mounting frame 401 is started to provide a force to drive the rotating plate 502 to rotate under force, and the rotating plate 502 is rotated under force to drive the two telescopic plates 603 to follow the rotation. The rotation of the two telescopic plates 603 drives the second limiting pulley 503 to rotate toward the inclined direction of the inclined facade wall 1. The second limiting pulley 503 approaches the inclined facade wall 1 so that the steel wire rope 305 passing through the middle is bent under force and close to the inclined facade wall 1. According to the angle and length of the inclined surface, the hydraulic cylinder 602 is started to telescope and drive the connected The telescopic plate 603 is subjected to force to telescope and adjust its length on the inner side of one end of the rotating plate 502, so that the distance between the second limiting pulley 503 and the first limiting pulley 402 is adjusted by extending or shortening the telescopic plate 603, thereby changing the length of the bending of the wire rope 305. At this time, the first limiting pulley 402 and the second limiting pulley 503 support and limit the wire rope 305, so that the wire rope 305 is bent close to the inclined facade wall 1 to make the construction platform 201 connected thereto be subjected to force to approach the inclined facade wall 1. In this way, the wire rope 305 can be bent along the rope limit, so that the construction platform 201 can be lifted and lowered along the bent wire rope 305 close to the inclined facade wall 1, so that the workers on the construction platform 201 can clean and wipe the glass windows on the inclined facade wall 1.

[0032] Further, the plug-in assembly 7 includes a mounting plug 701, a control pull rod 702, two transmission soft ropes 703, two limit blocks 704, two springs 705 and a mounting socket 706, one end of the mounting plug 701 is fixedly connected to the middle of one end of the mounting frame 401, the control pull rod 702 is slidably connected to the inside of the mounting plug 701 by penetrating the middle of one end of the mounting frame 401, the two limit blocks 704 are symmetrically slidably connected to the inner side of the side wall of the mounting plug 701, and one end of the two limit blocks 704 is fixedly connected to one end of the control pull rod 702 through two transmission soft ropes 703, the two ends of the two springs 705 are fixedly connected to the inner wall of the mounting plug 701 and one end of the limit block 704, the mounting socket 706 is opened on the side wall of the inclined facade wall 1, and the mounting plug 701 is matched with the mounting socket 706;

[0033] When the locking nut 706 is in the closed position, the locking nut 706 is engaged with the locking nut 708 and the locking nut 709 is engaged with the locking nut 709.

[0034] The implementation principle of the rope-following mechanism of a window cleaning machine in the embodiment of the present application is as follows: when in use, first, the control pull rod 702 is pulled outward to drive the two transmission soft ropes 703 to be pulled by force to pull the two limit blocks 704, so that the limit blocks 704 are forced to slide and retract into the inner side of the side wall of the installation plug 701. At this time, the installation plug 701 is aligned with the installation hole 706 opened on the side wall of the inclined facade wall 1 and inserted. The reaction force provided by the spring 705 causes the two limit blocks 704 to rebound and extend out. The two limit blocks 704 rebound and extend out to form a locking limit with the groove on the side wall of the installation hole 706, so that the installation frame 401 can be fixed on the side wall of the inclined facade wall 1. Similarly, the control pull rod 702 is pulled outward to drive the two The limiting card block 704 is forced to shrink and release the engagement with the side wall slot of the installation socket 706, and the installation plug 701 is pulled out from the installation socket 706, so that the installation frame 401 can be easily disassembled, thereby effectively simplifying the difficulty of loading and unloading the installation frame 401, and facilitating the purpose of convenient plug-in installation and disassembly of the installation frame 401. Secondly, after the installation frame 401 is fixedly installed on the side wall of the inclined facade wall 1, the wire rope 305 is passed through the first limiting pulley 402 and the second limiting pulley 503 to connect with the top of the construction platform 201. At this time, the second servo motor 501 supported and fixed by the installation frame 401 is started to provide a force to drive the rotating plate 502 to rotate under force. The rotation drives the two telescopic plates 603 to rotate accordingly, and the rotation of the two telescopic plates 603 drives the second limiting pulley 503 to rotate toward the inclined direction of the inclined external facade wall 1, and the second limiting pulley 503 approaches the inclined external facade wall 1 so that the steel wire rope 305 passing through the middle is bent by force and close to the inclined external facade wall 1, and according to the angle and length of the inclined surface, the hydraulic cylinder 602 is started to extend and retract, and the connected telescopic plate 603 is forced to extend and retract the inner side of one end of the rotating plate 502 to adjust the length, so that the distance between the second limiting pulley 503 and the first limiting pulley 402 is adjusted by extending or shortening the telescopic plate 603, thereby changing the length of the bending of the steel wire rope 305. At this time, the first limiting pulley 402 is used to adjust the distance between the second limiting pulley 503 and the first limiting pulley 402. The second limiting pulley 503 supports and limits the steel wire rope 305, so that the steel wire rope 305 is bent close to the inclined external facade wall 1 to force the construction platform 201 connected thereto to be close to the inclined external facade wall 1. In this way, the steel wire rope 305 can be bent along the rope limit, so as to effectively facilitate the construction platform 201 to be lifted and moved along the bent steel wire rope 305 close to the inclined external facade wall 1, so that the workers on the construction platform 201 can clean and wipe the glass windows on the inclined external facade wall 1. Finally, it is supported and fixed by the support frame 301 and the fixed block 302, and then the first servo motor 304 is started to provide a force to drive the rope roller 303 to rotate between the two fixed blocks 302.The rope roller 303 rotates to roll up or release the steel wire rope 305 wound thereon, and the steel wire rope 305 that has been bent along the rope limit is rolled up or released, thereby driving the construction platform 201 connected thereto to be forced to move up or down close to the inclined facade wall 1, and the lifting and lowering of the construction platform 201 facilitates the workers to clean the windows on the facade of the building.

[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
