DETAILED DESCRIPTION

[0025] like Figures 1 to 5 As shown, the present invention discloses a scaffolding suction cup-type tie device suitable for glass surfaces, comprising a scaffolding body 1, an extension rod 2 fixed to the scaffolding body 1 and extending in the normal direction of the glass 42, a sleeve 3 slidably mounted on the extension rod 2, and a first displacement drive device 4 mounted on the extension rod 2 and driving the sleeve 3 to slide. At least four tie assemblies 5 are evenly spaced around the sleeve 3. The scaffolding body 1 is a conventional structure, comprising at least horizontal and vertical crossbars. To ensure structural strength, the crossbars extend outward to form the extension rod 2. Under the action of the first displacement drive device 4, the sleeve 3 can slide along the extension rod 2. By simultaneously adjusting the pressure of each group of tie assemblies 5, the suction force of multiple groups of tie assemblies 5 can be adjusted, thereby improving the efficiency of the overall suction installation. It is understood that the number of tie assemblies 5 can be adjusted as needed, but it must be ensured that there is no interference between the tie assemblies 5 and the scaffolding body 1.

[0026] Specifically, the tie assembly 5 disclosed in the present invention includes a telescopic rod 6, a second displacement drive device 7, a one-way clamping assembly 8, an axle tube 9, a suction cup 10 and a connecting piece 11. The telescopic rod 6 can be telescoped and adjusted in length along its own length direction. The relative position between the tie device and the sliding sleeve 3 can be adjusted as needed, thereby changing the planar position of the tie, which can not only meet the actual adsorption position requirements, but also avoid interference with the scaffolding body 1.

[0027] A second displacement drive device 7 is mounted on the sleeve 3. The output end of the second displacement drive device 7 is connected to one end of a telescopic rod 6. The other end of the telescopic rod 6 extends radially along the sleeve 3 and is connected to a one-way clamping assembly 8. The one-way clamping assembly 8 is mated with an axle tube 9. When the second displacement drive device 7 drives the telescopic rod 6, it also drives the one-way clamping assembly 8 to move. A suction cup 10, which engages with the glass 42, is fixedly connected to one end of the axle tube 9. The suction cup 10 is equipped with a nozzle for extracting and releasing air. The axle tube 9 is fixed to the scaffold body 1 via a connector 11.

[0028] In an embodiment of the present invention, a pressure sensor is installed on the suction cup 10. The pressure sensor can be used to measure pressure and control the air pressure through the air nozzle, thereby controlling the adsorption force of a single tie assembly 5, so that the adsorption force of each group of tie assemblies 5 can be fine-tuned, thereby ensuring the uniformity of the adsorption force on the glass 42 panel and preventing damage to the glass 42 caused by the uneven force on the glass 42.

[0029] The working principle and process of the device of the present invention are as follows:

[0030] Step 1: After the tie assembly 5 is prepared, slide and install the first displacement drive device 4 and the sliding sleeve 3 on one of the extension rods 2.

[0031] Step 2: Allocate the number of groups of the required tie assemblies 5 around the sliding sleeve 3, set the angle of the sliding sleeve 3, and then match each group of the second displacement drive device 7 with the tie assemblies 5 one by one;

[0032] Step 3: Adsorb the suction cups 10 of each group of the fastening components 5 onto the glass 42, and adjust the first displacement driving device 4 to adjust the overall adsorption force;

[0033] Step 4: Control the air pressure through the air nozzle to control the adsorption force of each tie assembly 5, so that the adsorption force of each group of tie assemblies 5 can be fine-tuned to ensure that the pressure on each tie assembly 5 is consistent. The first displacement drive device 4 and the second displacement drive device 7 simultaneously provide pre-tension to the tie assemblies 5;

[0034] Step 5: Finally, the shaft tube 9 of the tie assembly 5 is connected and fastened to the scaffold body 1 through the connector 11 to form a stable scaffold tie device;

[0035] Step 6: After the shaft tube 9 is firmly connected to the scaffold body 1 , remove the one-way clamping assembly 8 , the sliding sleeve 3 and other components, and only keep the shaft tube 9 and the suction cup 10 connected to the scaffold body 1 .

[0036] In the embodiment of the present invention, two connecting pieces 11 are provided on the shaft tube 9, one of the connecting pieces 11 is used to connect with the scaffold body 1, and the other connecting piece 11 is a safety fastener to ensure the safety performance of the connection.

[0037] In the embodiment, the one-way clamping assembly 8 comprises a sleeve 12, a ball 13, a first spring 14 and an outer sleeve 15. The sleeve 12 is formed with an outer taper surface 16 at one end thereof facing the suction cup 10. The outer taper surface 16 is formed with a ball groove 17 for rolling cooperation with the ball 13. The outer sleeve 15 is sleeved on the outer side of the sleeve 12. The first spring 14 is arranged between the outer sleeve 15 and the sleeve 12. The inner side of the outer sleeve 15 is formed with an inner taper surface 18 corresponding to the outer taper surface 16. The one-way clamping assembly 8 can provide one-way tension for the shaft tube 9. When the outer sleeve 15 is displaced away from the suction cup 10, the outer taper surface 16 acts on the ball 13. The ball 13 cooperates with the shaft tube 9 after passing through the ball groove 17, thereby generating a friction force to drive the outer sleeve 15, the sleeve 12 and the shaft tube 9 to displace outward. When the outer sleeve 15 is displaced toward the suction cup 10, the inner taper surface 18 of the outer sleeve 15 is away from the ball 13 and does not act on the ball 13. At this time, the ball 13 also does not act on the shaft tube 9, so that one-way clamping action can be achieved.

[0038] In the embodiment, the outer sleeve 15 is threadedly connected with a nut 19 at one end thereof away from the inner taper surface 18. The end surface of the nut 19 is formed with a limiting surface 20 for connecting with the first spring 14. The nut 19 can be conveniently disassembled, so that the internal structure of the one-way clamping assembly 8 can be conveniently disassembled and assembled, thereby better coping with problems such as jamming.

[0039] In the embodiment, the first displacement driving device 4 comprises a fastener 21, a first shaft rod 22, a threaded cylinder 23 and a second shaft rod 24. The first shaft rod 22 and the second shaft rod 24 have opposite screw rotation directions and are threadedly connected at two ends of the threaded cylinder 23, respectively. The fastener 21 is arranged on the extension rod 2. The first shaft rod 22 is pivotally connected with the fastener 21. The second shaft rod 24 is pivotally connected with the sliding sleeve 3. The fastener 21 is detachably connected with the extension rod 2 of the scaffold. After the fastener 21 is fixed, the sliding sleeve 3 is installed. Since the first shaft rod 22 and the second shaft rod 24 have opposite screw rotation directions, when the threaded cylinder 23 is rotated, the relative position between the first shaft rod 22 and the second shaft rod 24 can be adjusted, thereby adjusting the position of the sliding sleeve 3.

[0040] In the embodiment, the second displacement driving device 7 comprises a rack 25, a gear 26 and a motor 27. The motor 27 is fixed on the outer side of the sliding sleeve 3. The output end of the motor 27 is connected to the gear 26. The gear 26 is engaged with the rack 25. The rack 25 is slidingly arranged in a sliding groove 28 formed on the outer side of the sliding sleeve 3. Through the driving action of the motor 27, the gear 26 can drive the rack 25 to displace along the sliding groove 28, thereby achieving adjustment of the position of the single binding assembly 5.

[0041] In this embodiment, the telescopic rod 6 includes an inner rod 29, an outer rod 30 and a locking member 31. The locking member 31 is a screw, which is threadedly connected to the outside of the outer rod 30. The inner end of the screw extends into the outer rod 30 and abuts against the inner rod 29. One end of the inner rod 29 is fixedly connected to the outer sleeve 15, and the other end of the inner rod 29 is slidably set in the outer rod 30. The outer rod 30 is fixedly connected to the output end of the second displacement drive device 7. The inner rod 29 and the outer rod 30 are locked by the locking member 31, and the telescopic length of the telescopic rod 6 can be adjusted.

[0042] In this embodiment, the suction cup 10 includes a fixed plate 32, a rotation drive device 33, a rotating cylinder 34, a steering gear 35, a flexible tube 36, and a suction cup body 37. The fixed plate 32 is fixedly connected to the shaft tube 9. One end of the rotating cylinder 34 rotates with the fixed plate 32, and the other end of the rotating cylinder 34 is connected to the suction cup body 37 via the flexible tube 36. The rotation drive device 33 is fixed to the fixed plate 32, and the output end of the rotation drive device 33 is connected to the rotating cylinder 34. A steering gear 35 is fixed to the outer side of the rotating cylinder 34, and the output end of the steering gear 35 is connected to the suction cup body 37. The rotation drive device 33 adopts a gear 26 and a ring gear. The rotation drive device 33 can control the rotation of the rotating cylinder 34 about its axis, and the steering gear 35 can control the deflection angle of the suction cup body 37. The cooperation between the rotation drive device 33 and the steering gear 35 can adjust the suction angle of the suction cup body 37 to accommodate glass 42 at different angles, ensuring that the suction cup body 37 always adheres to the glass 42, providing a more secure suction force.

[0043] In this embodiment, a boss 38 is formed on the inner side of the rotating drum 34, and the boss 38 is connected to a small suction cup 40 through a second spring 39. The small suction cup 40 and the working surface of the suction cup body 37 are located in the same plane. The small suction cup 40 is connected to the air pump through a hose 41, and the hose 41 passes through the shaft tube 9. By providing the small suction cup 40, additional protection can be provided when the suction cup 10 falls off, thereby increasing the safety of the overall structure.

[0044] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
