[0033] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0034] This application discloses a safety protection device for a window cleaning machine. (Refer to...) Figure 1 The safety protection device for the window cleaning machine includes a mounting frame 1 for installation on a gondola. The mounting frame 1 is also equipped with a moving mechanism 2 and a suction mechanism 3. The moving mechanism 2 includes a mounting frame 21 and a moving component 22. The moving component 22 is used to drive the mounting frame 21 closer to the building glass. The suction mechanism 3 includes a suction cup 31 and a negative pressure component 32. The suction cup 31 is mounted on the mounting frame 21 and is used to abut against the building glass. The negative pressure component 32 is used to generate negative pressure between the suction cup 31 and the glass.

[0035] Reference Figure 1 and Figure 2 The mounting frame 1 is also equipped with a rotating seat 4, which is fixedly installed on the side wall of the gondola. One end of the mounting frame 1 is embedded in the rotating seat 4 and is rotatably connected to the rotating seat 4 via a bearing. The rotating seat 4 is also equipped with a rotating mechanism 5, which includes a rotating motor 51 and two rotating gears 52. The rotating motor 51 is fixedly installed on the rotating seat 4, and its output shaft is parallel to the rotation axis of the rotating seat 4.

[0036] Reference Figure 1 and Figure 2 One rotating gear 52 is fixedly sleeved on the output shaft of the rotating motor 51, and the other rotating gear 52 is fixedly sleeved on the mounting base. The two rotating gears 52 are meshed together so that the rotating motor 51 can drive the mounting frame 1 to rotate through the rotating gears 52, thereby realizing the drive of the mounting frame 1 to rotate.

[0037] Reference Figure 2In other embodiments, the rotating mechanism 5 may also be configured as a rotating cylinder. The cylinder body of the rotating cylinder is rotatably connected to the rotating seat 4 through a support and a pin. The piston rod of the rotating cylinder is rotatably connected to the side of the mounting frame 1 that is different from its own rotation axis through a pin, so that the rotating cylinder can drive the mounting frame 1 to slide by driving the piston rod to slide.

[0038] Reference Figure 1 , Figure 3 and Figure 4 The number of moving mechanisms 2 and suction cups 31 is set to several. In this embodiment, the number of moving mechanisms 2 and suction cups 31 is set to two, and they are correspondingly arranged and located at both ends of the mounting frame 1 along its own length. Each moving mechanism 2 also includes a moving frame 23, and each moving mechanism 2 has two moving frames 23 and two moving components 22, which are located on opposite sides of the corresponding mounting frame 21.

[0039] Reference Figure 1 , Figure 3 and Figure 4 Each moving component 22 includes a closed-loop frame 221 and a drive component 222. Each closed-loop frame 221 is located at the end of the mounting frame 1 and is fixedly connected to the mounting frame 1 by welding. Each closed-loop frame 221 has a closed-loop groove 6, each closed-loop groove 6 is enclosed, and each closed-loop groove 6 has a portion extending along the width direction of the mounting frame 1.

[0040] Reference Figure 4 and Figure 5 Each movable frame 23 is provided with a plurality of rollers 24. In this embodiment, each movable frame 23 is provided with two rollers 24, which are distributed along the direction of extension of the closed-loop groove 6. Each roller 24 is rotatably connected to the corresponding movable frame 23 by a pin and is disposed in the corresponding closed-loop groove 6, with its sidewall abutting against the inner sidewall of the corresponding closed-loop groove 6, so that the roller 24 drives the movable frame 23 to move along the extension direction of the closed-loop groove 6.

[0041] Reference Figure 4 and Figure 5 Each driving component 222 includes a driving frame 2221, a transmission frame 2222, and a driving motor 2223. In this embodiment, each driving motor 2223 is configured as a geared motor. Each driving motor 2223 is fixedly mounted on the corresponding closed-loop frame 221 and is located in the inner middle of the corresponding closed-loop groove 6. The axial direction of the output shaft of each driving motor 2223 is perpendicular to the extension direction of the corresponding closed-loop groove 6.

[0042] Reference Figure 4 and Figure 5Each drive motor 2223 is located on the opposite side of the closed-loop slot 6 on the corresponding closed-loop frame 221, and its output shaft passes through the corresponding closed-loop frame 221 and reaches the other side of the corresponding closed-loop frame 221. Each drive frame 2221 is fixedly installed at the end of the output shaft of the corresponding drive motor 2223, so that the drive motor 2223 can drive the corresponding drive frame 2221 to rotate.

[0043] Reference Figure 4 and Figure 5 Each drive frame 2221 is sleeved on a corresponding transmission frame 2222 and slidably connected to the transmission frame 2222. The sliding direction of the drive frame 2221 relative to the transmission frame 2222 is the length direction of the transmission frame 2222 itself. One end of each transmission frame 2222 is rotatably connected to the side of the corresponding movable frame 23 away from the corresponding mounting frame 1 by a pin, so that when the transmission frame 2222 rotates with the drive frame 2221, the end can drive the corresponding movable frame 23 to slide.

[0044] Reference Figure 3 and Figure 5 In this embodiment of the application, the rotation axes of the two drive motors 2223 in the same moving mechanism 2 are the same, and the two moving frames 23 in the same moving mechanism 2 are located at the same position of the corresponding closed loop groove 6, so that the moving trajectories of the two moving frames 23 in the same moving mechanism 2 are set in parallel.

[0045] Reference Figure 3 Each mounting frame 21 is located on the side of its corresponding transmission frame 2222 away from its corresponding moving frame 23, and each mounting frame 21 is rotatably connected to its corresponding moving frame 23 via a pin. In this embodiment, each mounting frame 21 and its corresponding transmission frame 2222 share the same pin to ensure the driving stability of the mounting frame 21. In this embodiment, the rotatable connections between the two mounting frames 21 within the same moving mechanism 2 and their corresponding drive frames 2221 are located at different positions to accommodate the positions of the two mounting frames 21 themselves.

[0046] Reference Figure 3 and Figure 4 Each moving mechanism 2 also includes a positioning element 25, and the number of positioning elements 25 in each moving mechanism 2 is set to two, corresponding one-to-one with the setting frame 21. Each closed-loop frame 221 has a sliding part 2211 at the end away from the suction cup 31, and each sliding part 2211 is fixedly connected to the corresponding closed-loop frame 221 by welding. One end of each positioning frame 251 is sleeved on the corresponding sliding part 2211 and is slidably connected to the corresponding sliding part 2211, and the sliding direction is set to the length direction of the corresponding sliding part 2211.

[0047] Reference Figure 3 andFigure 4 Each positioning frame 251 has its other end extending towards the mounting frame 21, and in this embodiment, this extension direction is the width direction of the corresponding closed-loop frame 221. The end of each positioning frame 251 away from the sliding portion 2211 extends into the corresponding mounting frame 21, so that the end of the mounting frame 21 is fitted onto the end of the positioning frame 251. Each positioning frame 251 is slidably connected to the corresponding mounting frame 21, and the sliding direction is the length direction of the positioning frame 251 itself.

[0048] Reference Figure 1 , Figure 4 and Figure 5 When the output shaft of the drive motor 2223 rotates, it drives the corresponding drive frame 2221 to rotate, which in turn drives the transmission frame 2222 to rotate together. During this process, the end of the transmission frame 2222 causes the corresponding moving frame 23 to move, and the rollers 24 on the moving frame 23 move along the extension direction of the closed-loop groove 6 under the constraint of the inner wall of the closed-loop groove 6, thereby causing the moving frame 23 to move along the extension direction of the closed-loop groove 6.

[0049] Reference Figure 1 , Figure 4 and Figure 5 During this process, the end of the transmission frame 2222 slides relative to the corresponding drive frame 2221, thereby adapting to the change in distance between the moving frame 23 and the drive motor 2223. As the moving frame 23 moves, it causes the setting frame 21 to move as well. At this time, under the constraint of the positioning frame 251, the setting frame 21 only moves relative to the closed-loop frame 221, and slides relative to the closed-loop frame 221 to adapt to the change in its position. When the moving frame 23 moves to the turning point of the closed-loop groove 6, the moving frame 23 itself rotates under the drive of the two rollers 24, thereby causing the moving frame 23 to rotate relative to the setting frame 21.

[0050] Reference Figure 3 In each moving mechanism 2, an adjustment mechanism 7 is provided between the two closed-loop frames 221. Each adjustment mechanism 7 includes an adjustment frame 71 and an adjustment component 72. Two adjustment parts 711 extend from the adjustment frame 71, and the adjustment parts 711 are correspondingly arranged with the setting frame 21. One end of each adjustment part 711 extends to the corresponding setting frame 21 and is slidably connected to the corresponding setting frame 21. The sliding direction is the same, which is the length direction of the corresponding positioning frame 251.

[0051] Reference Figure 3The adjustment component 72 is mounted on one of its mounting frames 21. In this embodiment, the adjustment component 72 is configured as a combination structure of a reduction motor and a lead screw. Each reduction motor is fixedly mounted on a corresponding mounting frame 21, and the extension direction of its output shaft is the same as the sliding direction of the adjustment part 711. Each motor is fixedly connected to one end of the corresponding lead screw via a coupling. Each lead screw extends beyond the mounting frame 21 through the corresponding adjustment part 711 and is threadedly connected to that portion of the corresponding adjustment part 711. Both ends of each lead screw are rotatably connected to the corresponding mounting frame 21.

[0052] In other embodiments, the adjustment component 72 may also be configured as an electric telescopic rod, which is fixedly installed on a corresponding mounting frame 21, and the piston rod is fixedly connected to the corresponding adjustment part 711.

[0053] Reference Figure 1 Two suction cups 31 are respectively fixedly installed at the ends of the two adjusting frames 71 away from the closed-loop frame 221. In this embodiment, the negative pressure assembly 32 is a combination structure of a vacuum generator and a hose. The vacuum negative pressure generator is fixedly installed on the side wall of the gondola away from the suction cups 31. Two hoses are provided, and one end of each hose is connected to the vacuum negative pressure generator, and the other end is connected to the corresponding suction cup 31, so that the vacuum negative pressure generator can create a vacuum between the suction cup 31 and the building glass through the hoses.

[0054] Reference Figure 1 , Figure 3 and Figure 5 In this embodiment, the operator controls the speed and rotation angle of the drive motor 2223 in the two moving mechanisms 2 to change the position of the moving frame 23 in the different moving mechanisms 2. As a result, when the gondola moves under the drive of the wire rope, there is always a suction cup 31 adhering to the glass of the building. When the suction cup 31 is adhering, the moving component 22 corresponding to the suction cup 31 can drive the suction cup 31 to move relative to the gondola, thereby making the suction cup 31 adapt to the movement of the gondola.

[0055] The implementation principle of a safety protection device for a window cleaning machine according to an embodiment of this application is as follows: During use, each drive motor 2223 drives the corresponding drive frame 2221 to rotate, and the drive frames 2221 in different moving mechanisms 2 are located at different positions in the corresponding closed-loop groove 6, so that only one suction cup 31 is present to adsorb the building glass. In this process, the drive frame 2221 drives the moving frame 23 to move along the extension direction of the closed-loop groove 6 through the transmission frame 2222, thereby causing the moving frame 23 to drive the corresponding setting frame 21 to move, and causing the setting frame 21 to drive the corresponding adjusting frame 71 and suction cup 31 to move.

[0056] During this process, the suction cup 31 adsorbed on the building glass moves in the opposite direction to the direction of the gondola's movement relative to the mounting frame 1, and moves away from the building glass relative to the mounting frame 1 in the direction of the gondola's movement, thereby adapting to the movement of the gondola.

[0057] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
