Description

Technical Field

[0001] This utility model relates to the field of high-altitude maintenance equipment technology, specifically to a mobile device for cleaning glass skylights. Background Technology

[0002] With the widespread use of large public buildings such as airports, stadiums, and commercial complexes in modern society, curved glass skylights have gradually become a popular choice in these architectural designs due to their unique lighting effects and aesthetic value. These curved glass skylight structures are typically installed at heights of 20 to 50 meters above the ground. Due to their height and structural uniqueness, their cleaning and maintenance face significant challenges and difficulties.

[0003] Currently, under existing technological conditions, maintenance of curved glass skylights largely relies on manual suspended platforms or fixed track equipment. However, due to the complex and diverse shapes of curved glass, the tilt angle of the skylight varies significantly in different locations. This makes it difficult for traditional cleaning equipment to maintain a level platform during operation, severely impacting cleaning effectiveness and work efficiency. Furthermore, operating manual suspended platforms is inherently risky; the platforms are prone to swaying and lack stability, posing significant safety hazards to operators. Additionally, using manual suspended platforms requires repeated positioning and anchor point fixing, a process that is not only time-consuming and labor-intensive but also further increases the difficulty and risk of the operation, making efficient and safe cleaning difficult. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mobile device for cleaning glass skylights. It overcomes the deficiencies of existing technologies, has a reasonable design, and solves the technical problems of existing equipment being unable to adapt to curved surfaces and having poor stability of the working platform, thus significantly improving the safety and efficiency of high-altitude cleaning.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A mobile device for cleaning glass skylights includes a mobile platform and an installation platform. A connecting block is fixedly connected to the lower part of the mobile platform, and a sliding frame is fixedly connected to the lower end of the connecting block. The sliding frame is slidably connected within a square tube frame track of the glass skylight. A guide steel rope is installed parallel to the axial direction within the square tube frame track. The guide steel rope passes through the sliding frame. A drive wheel is rotatably connected within the sliding frame via a rotating shaft. The outer circumference of the drive wheel engages in frictional contact with the guide steel rope. A drive motor is fixedly installed on the mobile platform, and the drive shaft of the drive motor is connected to the drive wheel via a transmission component.

[0007] Multiple first hinge seats are fixedly installed on the upper surface of the mobile platform, and multiple second hinge seats are installed on the lower surface of the mounting platform. The first hinge seats and the second hinge seats are connected one-to-one by electric push rods.

[0008] Preferably, horizontal pivot seats are fixedly installed at both ends of the front and rear sides of the sliding frame, and vertical guide wheels are rotatably connected to the horizontal pivot seats via horizontal pivots. The vertical guide wheels are in contact with the upper and lower walls of the inner cavity of the square tube frame track.

[0009] Preferably, vertical pivot seats are fixedly installed at both ends of the sliding frame, and horizontal guide wheels are rotatably connected to the vertical pivot seats via vertical pivots. The horizontal guide wheels are in contact with the front and rear side walls of the inner cavity of the square tube frame track.

[0010] Preferably, the outer circumference of the drive wheel is provided with a groove, and the guide steel rope is movably embedded in the groove.

[0011] Preferably, the electric actuators are provided in six groups, and the six groups of electric actuators are not completely symmetrically arranged, and each electric actuator is set at an inclined angle.

[0012] Preferably, a limiting hollow cylinder is fixedly installed parallel to the axial direction in the middle of the sliding frame, the guide steel rope passes through the limiting hollow cylinder, a through hole is opened on the surface of the limiting hollow cylinder, and the drive wheel passes through the through hole and makes frictional contact with the guide steel rope.

[0013] This utility model provides a mobile device for cleaning glass skylights, which has the following advantages: By controlling the output shaft of the drive motor to drive the drive wheel to rotate, the drive wheel can be axially displaced relative to the guide steel rope through the frictional contact between the drive wheel and the guide steel rope. This causes the sliding frame to move along the square tube frame track, thereby driving the mobile platform to move smoothly on the glass skylight. During the movement, multiple sets of electric push rods can form a spatial parallel mechanism. By independently controlling the extension and retraction length of each electric push rod, the position and posture of the installation platform can be precisely adjusted to ensure that the installation platform can maintain a horizontal state on the curved glass skylight, thereby ensuring that the cleaning robot or worker can carry out cleaning operations efficiently and safely.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0024] Example 1, as Figure 1-6 As shown, a mobile device for cleaning glass skylights includes a mobile platform 1 and an installation platform 11. A connecting block 2 is fixedly connected to the bottom of the mobile platform 1, and a sliding frame 3 is fixedly connected to the lower end of the connecting block 2. The sliding frame 3 is slidably connected in the square tube frame track 4 of the glass skylight. A guide steel rope 5 is installed parallel to the axial direction in the square tube frame track 4. The guide steel rope 5 passes through the sliding frame 3. A drive wheel 6 is rotatably connected in the sliding frame 3 through a rotating shaft. The outer circumference of the drive wheel 6 is in frictional contact with the guide steel rope 5. A drive motor 7 is fixedly installed on the mobile platform 1. The drive shaft of the drive motor 7 is connected to the drive wheel 6 through a transmission belt.

[0025] Multiple first hinge seats 8 are fixedly installed on the upper surface of the mobile platform 1, and multiple second hinge seats 9 are installed on the lower surface of the mounting platform 11. The first hinge seats 8 and the second hinge seats 9 are connected one-to-one by electric push rods 10.

[0026] Working principle:

[0027] Before use, the cleaning robot or worker enclosure can be installed on the upper surface of the installation platform 11, so that the cleaning robot or worker can carry out cleaning operations on the glass skylight.

[0028] During use, the output shaft of the drive motor 7 is controlled to drive the drive wheel 6 to rotate. Then, through the frictional contact between the drive wheel 6 and the guide steel rope 5, the drive wheel 6 can be axially displaced relative to the guide steel rope 5, thereby causing the sliding frame 3 to move along the square tube frame track 4, so as to drive the moving platform 1 to move smoothly on the glass skylight. During the movement, multiple sets of electric push rods 10 can form a spatial parallel mechanism. By independently controlling the extension and retraction length of each electric push rod 10, the position and posture of the installation platform 11 can be precisely adjusted to ensure that the installation platform 11 can maintain a horizontal state on the curved glass skylight, thereby ensuring that the cleaning robot or worker can carry out cleaning operations efficiently and safely.

[0029] In this embodiment, a three-axis tilt sensor can be installed on the mounting platform 11. The signal output terminal of the three-axis tilt sensor is connected to the signal input terminal of the control unit, and the signal output terminal of the control unit is connected to the drive unit of each electric push rod 10. Thus, the tilt angle of the mounting platform 11 can be monitored in real time through the three-axis tilt sensor, and the extension and retraction of each electric push rod 10 can be precisely adjusted through the control unit to ensure that the mounting platform 11 is always parallel to the glass surface, thereby effectively ensuring the stability of the mounting platform 11.

[0030] In addition, in this embodiment, a clamping device can be installed inside the sliding frame 3. When the equipment stops moving, the clamping device can lock the guide steel rope 5, thereby preventing the sliding frame 3 from sliding unexpectedly within the square tube frame track 4, ensuring the safety and stability of the equipment in a static state, and further improving the overall safety and efficiency of the cleaning operation. In this utility model, the clamping device adopts a well-known technical solution in the prior art, which is already understood by those skilled in the art and will not be described in detail here.

[0031] In this utility model, such as Figure 6 As shown, a unit panel transport rack 18 can also be fixedly mounted on the installation platform 11. This allows for quick and convenient transportation and handling of unit panels when replacement or repair of certain glass skylight unit panels is required, improving overall maintenance efficiency and reducing the burden and risks of manual handling. The unit panel transport rack 18 is rationally designed and structurally stable, ensuring the safe and undamaged handling of the skylight unit panels during transport, effectively improving both work efficiency and safety.

[0032] Example 2, as Figure 4As shown, in a further preferred embodiment, horizontal pivot seats 12 are fixedly installed at both the left and right ends of the front and rear sides of the sliding frame 3. Vertical guide wheels 13 are rotatably connected to the horizontal pivot seats 12 via horizontal pivot shafts. The vertical guide wheels 13 are in contact with the upper and lower walls of the inner cavity of the square tube frame track 4. In this embodiment, horizontal pivot seats 12 and vertical guide wheels 13 can be provided above and below the left and right ends of the front and rear sides of the sliding frame 3. Thus, the contact action between the eight vertical guide wheels 13 and the upper and lower walls of the inner cavity of the square tube frame track 4 can effectively ensure the smooth operation of the sliding frame 3 within the square tube frame track 4, further enhancing the adaptability and stability of the equipment on complex curved surfaces.

[0033] Example 3, as Figure 5 As shown, in a further preferred embodiment, vertical pivot seats 14 are fixedly installed at both ends of the sliding frame 3. Horizontal guide wheels 15 are rotatably connected to the vertical pivot seats 14 via vertical pivots. The horizontal guide wheels 15 contact the front and rear side walls of the inner cavity of the square tube frame track 4. In this embodiment, eight horizontal guide wheels 15 are provided, located at the front and rear of the upper and lower sides of the left and right ends of the sliding frame 3, respectively. The contact action between the eight horizontal guide wheels 15 and the front and rear side walls of the inner cavity of the square tube frame track 4 ensures the smooth horizontal movement of the sliding frame 3 within the track, further enhancing the adaptability and stability of the equipment on complex curved surfaces.

[0034] In Example 4, as a further preferred embodiment of Example 1, a groove 16 is formed around the outer circumference of the drive wheel 6, and the guide steel rope 5 is movably embedded in the groove 16. Through the engagement of the groove 16 and the guide steel rope 5, the stable operation of the guide steel rope 5 within the groove 16 is effectively ensured, preventing accidental derailment and further improving the operational safety and cleaning effect of the equipment in complex environments. In this embodiment, an anti-slip coating can also be added to the inner wall of the groove 16 to enhance the friction with the guide steel rope 5, thereby further ensuring the friction effect between the guide steel rope 5 and the groove 16, preventing slippage failure due to insufficient friction, and improving overall operational stability.

[0035] In Example 5, as a further preferred embodiment of Example 1, six sets of electric actuators 10 are provided, and the six sets of electric actuators 10 are not completely symmetrically arranged, with each electric actuator 10 set at an inclined angle. The first hinge seat 8 and the second hinge seat 9 are located at the corner positions of the moving platform 1 and the mounting platform 11, respectively. Thus, by independently controlling the extension and retraction of the six sets of electric actuators 10, the multi-angle pose adjustment effect of the mounting platform 11 can be achieved, ensuring that the mounting platform 11 can maintain a horizontal state in different positions, further improving the operating accuracy and stability of the equipment on complex curved surfaces.

[0036] In Example 6, as a further preferred embodiment of Example 1, a limiting hollow cylinder 17 is fixedly installed parallel to the axial direction in the middle of the sliding frame 3. The guide steel rope 5 passes through the limiting hollow cylinder 17, and a through hole is opened on the surface of the limiting hollow cylinder 17. The drive wheel 6 passes through the through hole and engages in frictional contact with the guide steel rope 5. The limiting hollow cylinder 17 can effectively limit the guide steel rope 5, preventing it from deviating during operation and ensuring that the drive wheel 6 can always maintain close contact with the guide steel rope 5.

[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
