DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0028] In specific embodiments, as shown in Figs. 1-3 the basic use process of the cleaning frame is disclosed;

[0029] The support frame 1 and the fixed frame 2 fixedly installed on the upper end of the support frame 1 are shown in the figure.

[0030] The moving piece 3 is slidably installed in the support frame 1, the pulley assembly 4 is rotatably installed in the moving piece 3, the connecting piece 5 is fixedly installed on one end of the moving piece 3 close to the support frame 1, the moving rod piece 6 is fixedly installed on the other end of the moving piece 3 away from the connecting piece 5, the sliding piece 7 is slidably installed in the moving rod piece 6, and the climbing frame 8 is threadedly installed on the outer side of the sliding piece 7.

[0031] The drive motor 9 and the speed reducer 10 are fixedly installed on the outer side of the fixed frame 2, and the output end of the drive motor 9 is fixedly connected with the speed reducer 10.

[0032] When using the hidden pulley cleaning frame, the climbing frame 8 needs to be installed outside the sliding piece 7, and then the cleaning frame can work. During the working process of the cleaning frame, the driving motor 9 drives the winding wheel assembly 11 to rotate through the speed reducer 10. The winding wheel assembly 11 winds the steel wire rope 13 and makes the moving piece 3 support the inside of the frame 1 to move. At this time, the height of the climbing frame 8 can be adjusted through the moving rod 6. Then the operator can climb to the upper end of the climbing frame 8 and clean the upper end of the equipment placed at the lower end of the fixed frame 2, thereby completing the working process of the device and effectively improving the safety of the cleaning frame movement.

[0033] In one embodiment, as shown in Figs. 1-4 , the specific operation process of the device is disclosed;

[0034] The output end of the speed reducer 10 is fixedly installed with the winding wheel assembly 11, and the winding wheel assembly 11 is rotationally connected with the fixed frame 2, and the end of the winding wheel assembly 11 away from the speed reducer 10 is located inside the fixed frame 2.

[0035] The inside of the support frame 1 is rotationally installed with the guide wheel assembly 12, and the outside of the guide wheel assembly 12 is wound with the steel wire rope 13, and the two ends of the steel wire rope 13 are fixedly connected with the connecting piece 5 and the winding wheel assembly 11 respectively.

[0036] When using the hidden pulley cleaning frame, the driving motor 9 drives the winding wheel assembly 11 to rotate through the speed reducer 10, and the winding wheel assembly 11 winds the steel wire rope 13 fixedly installed outside it. At this time, the steel wire rope 13 pulls the connecting piece 5 to move upward, and the movement of the connecting piece 5 drives the moving piece 3 to move synchronously. At this time, the moving piece 3 makes the pulley assembly 4 roll inside the support frame 1, thereby reducing the friction between the moving rod 6 and the climbing frame 8 and the support frame 1 during the upward and downward movement, improving the smoothness of the upward and downward movement of the moving rod 6 and the climbing frame 8, thereby ensuring the safety of the cleaning frame in use, and ensuring the beauty of the structure in use.

[0037] On the basis of the above embodiment, as shown in Figs. 1-6 , the process of the cleaning frame suitable for different sizes of climbing frame 8 is disclosed;

[0038] The upper end of the moving rod 6 is fixedly installed with a servo motor 14, the output end of the servo motor 14 is fixedly installed with an output shaft 15, the inside of the moving rod 6 is rotationally installed with a threaded rod 16, and the outside of the threaded rod 16 and the output shaft 15 is sleeved with a belt pulley structure.

[0039] A reciprocating screw rod 17 is rotatably mounted inside the moving rod 6, and the reciprocating screw rod 17 and the threaded rod 16 are symmetrical about the vertical center axis of the moving rod 6, and the reciprocating screw rod 17 and the threaded rod 16 are both threadedly connected to the sliding member 7;

[0040] A rotating cylinder 18 is fixedly mounted on one end of the reciprocating screw 17 close to the threaded rod 16, and the rotating cylinder 18 is rotatably connected to the moving rod 6. A ratchet 19 is fixedly mounted on the outer side of the threaded rod 16, and the ratchet 19 is located inside the rotating cylinder 18.

[0041] A fixed shaft 20 is fixedly installed inside the rotating cylinder 18 , and a ratchet 22 is rotatably installed outside the fixed shaft 20 . A torsion spring 21 is nested inside the ratchet 22 , and the torsion spring 21 is located outside the fixed shaft 20 .

[0042] When the hidden pulley cleaning frame is used, the two sets of sliding members 7 need to be moved to the required positions according to the size of the climbing frame 8. When the climbing frame 8 is centered at the lower end of the moving rod 6, the servo motor 14 needs to be operated and drive the output shaft 15 to rotate. The rotation of the output shaft 15 will drive the threaded rod 16 to rotate through the pulley structure. At this time, the threaded rod 16 will rotate synchronously with the output shaft 15, and at this time the ratchet 19 and the ratchet teeth 22 are in meshing state. The threaded rod 16 will drive the rotating cylinder 18 to rotate through the ratchet 19 and the ratchet teeth 22, and the rotating cylinder 18 will drive the reciprocating screw rod 17 to rotate. At this time, the threaded rod 16 and the reciprocating screw rod 17 will drive the two sets of sliding members 7 to move and move away from each other. When the two sets of sliding members 7 are the same width as the climbing frame 8, they stop moving. At this time, the climbing frame 8 can be threadedly connected to the two sets of sliding members 7;

[0043] When installing the climbing frame 8 in a different position, it is necessary to make the servo motor 14 drive the output shaft 15 to rotate in the opposite direction. At this time, the threaded rod 16 will rotate with the output shaft 15, and the ratchet 19 will be in a separated state from the ratchet teeth 22. The torsion spring 21 will expand and contract to cooperate with the movement of the ratchet teeth 22, which will make the threaded rod 16 drive the sliding member 7 to move, thereby changing the position of the two sets of sliding members 7. The climbing frame 8 can be installed on the outside of the two sets of sliding members 7 in this state, thereby changing the position of the climbing frame 8, effectively improving the convenience of using the device and increasing the overall practicality.

[0044] The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0045] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
