DETAILED DESCRIPTION

[0018] like Figures 1 to 5 As shown, the present invention discloses a scaffold suction cup type tie device suitable for glass surface, comprising a scaffold body 1, an extension rod 2 fixed on the scaffold body 1 and extending along the normal direction of the glass 42, a sliding sleeve 3 slidably arranged on the extension rod 2, and a first displacement driving device 4 installed on the extension rod 2 and driving the sliding sleeve 3 to slide, and at least four tie assemblies 5 are evenly spaced around the circumference of the sliding sleeve 3; the scaffold body 1 is an existing structure, at least including horizontal and vertical cross bars and vertical bars, and in order to ensure the structural strength, the cross bars extend outward to form the extension rod 2. Under the action of the first displacement driving device 4, the sliding sleeve 3 can slide along the extension rod 2, and by adjusting the pressure of each group of tie assemblies 5 at the same time, the adsorption force of multiple groups of tie assemblies 5 can be adjusted as a whole, thereby improving the efficiency of the overall adsorption installation. It can be understood that the number of tie assemblies 5 is adjusted as needed, but it is necessary to ensure that there is no interference between the tie assemblies 5 and the scaffold body 1.

[0019] 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 telescopically adjusted along its own length direction, and the relative position between the tie assembly 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.

[0020] The second displacement driving device 7 is installed on the sliding sleeve 3, and the output end of the second displacement driving device 7 is connected to one end of the telescopic rod 6. The other end of the telescopic rod 6 is connected to the one-way clamping assembly 8 along the radial extension of the sliding sleeve 3, and the one-way clamping assembly 8 cooperates with the shaft tube 9. When the second displacement driving device 7 drives the telescopic rod 6 to move, it can also drive the one-way clamping assembly 8 to move. One end of the shaft tube 9 is fixedly connected to a suction cup 10 that cooperates with the glass 42, and the suction cup 10 is provided with an air nozzle for extracting and releasing air. The shaft tube 9 is fixed to the scaffold body 1 by a connecting piece 11.

[0021] In the 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 an 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.

[0022] The working principle and process of the device of the present invention are as follows: Step 1: After the tie assembly 5 is prepared, the first displacement drive device 4 and the sliding sleeve 3 are slidably installed on one of the extension rods 2. Step 2: Allocate the number of groups of the tie assemblies 5 required around the sliding sleeve 3, set the angle of the sliding sleeve 3, and then correspond each group of the second displacement driving devices 7 and the tie assemblies 5 one by one; Step 3: Adsorb the suction cups 10 of each group of the tie assembly 5 onto the glass 42, and adjust the first displacement driving device 4 to adjust the overall adsorption force; Step 4: Control the air pressure through the air nozzle to control 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, so that the pressure on each tie assembly 5 is consistent, and the first displacement drive device 4 and the second displacement drive device 7 simultaneously provide pre-tensioning force for the tie assembly 5; Step 5: Finally, the shaft tube 9 of the tie assembly 5 is connected and fastened to the scaffold body 1 through the connecting piece 11 to form a stable scaffold tie device; 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 .

[0023] In the embodiment of the present invention, two connecting pieces 11 are arranged 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.

[0024] In this embodiment, the one-way clamping assembly 8 includes a sleeve 12, a ball 13, a first spring 14 and an outer sleeve 15. The sleeve 12 forms an outer conical surface 16 at one end facing the suction cup 10. A ball groove 17 for rolling with the ball 13 is provided on the outer conical surface 16. The outer sleeve 15 is slidably sleeved on the outer side of the sleeve 12. The first spring 14 is installed between the outer sleeve 15 and the sleeve 12. An inner conical surface 18 corresponding to the outer conical surface 16 is formed on the inner side of the outer sleeve 15. By setting the one-way clamping assembly 8, a one-way pulling force can be applied to the shaft tube 9. The specific effect is that when the outer sleeve 15 moves toward the side away from the suction cup 10, the outer conical surface 16 acts on the ball 13. After the ball 13 passes through the ball groove 17, it cooperates with the shaft tube 9, thereby generating friction, driving the outer sleeve 15, the sleeve 12 and the shaft tube 9 to move outward together. When the outer sleeve 15 moves toward the side close to the suction cup 10, the inner conical 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 does not act on the shaft tube 9 either, so a one-way clamping effect can be achieved.

[0025] In this embodiment, a nut 19 is threadedly connected to one end of the outer sleeve 15 away from the inner conical surface 18, and the end face of the nut 19 forms a limiting surface 20 for connecting with the first spring 14, which can facilitate the disassembly of the nut 19, thereby facilitating the disassembly and assembly of the internal structure of the one-way clamping assembly 8, so as to better deal with problems such as sticking.

[0026] In this embodiment, the first displacement driving device 4 includes a fastener 21, a first shaft 22, a threaded barrel 23, and a second shaft 24. The first shaft 22 and the second shaft 24 have opposite thread directions and are respectively threadedly connected to the two ends of the threaded barrel 23. The fastener 21 is installed on the extension rod 2, the first shaft 22 is pivoted to the fastener 21, and the second shaft 24 is pivoted to the sliding sleeve 3. The fastener 21 is detachably connected to the extension rod 2 of the scaffold, and the sliding sleeve 3 is installed after the fastener 21 is fixed. Since the first shaft 22 and the second shaft 24 have opposite thread directions, when the threaded barrel 23 is rotated, the relative position between the first shaft 22 and the second shaft 24 can be adjusted, thereby adjusting the position of the sliding sleeve 3.

[0027] In this embodiment, the second displacement driving device 7 includes a rack 25, a gear 26 and a motor 27. The motor 27 is fixed to the outside of the sliding sleeve 3. The output end of the motor 27 is connected to the gear 26. The gear 26 is meshed with the rack 25. The rack 25 is slidably installed in a slide groove 28 provided on the outside of the sliding sleeve 3. Through the driving action of the motor 27, the gear 26 can drive the rack 25 to move along the slide groove 28, thereby realizing the adjustment of the position of a single tie assembly 5.

[0028] In this embodiment, the telescopic rod 6 includes an inner rod 29, an outer rod 30 and a locking piece 31. The locking piece 31 is a screw. The screw is threadedly connected to the outer side 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 arranged in the outer rod 30. The outer rod 30 is fixedly connected to the output end of the second displacement driving device 7. The inner rod 29 and the outer rod 30 are locked by the locking piece 31, and the telescopic length of the telescopic rod 6 can be adjusted.

[0029] 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 cylinder 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 is rotationally matched with the fixed plate 32, and the other end of the rotating cylinder 34 is connected to the suction cup body 37 through the flexible cylinder 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. The steering gear 35 is fixed to the outside 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 the matching mode of the gear 26 and the gear ring. By setting the rotation drive device 33, the rotating cylinder 34 can be controlled to rotate around its axis. By setting the steering gear 35, the deflection angle of the suction cup body 37 can be controlled. By matching the rotation drive device 33 with the steering gear 35, different adsorption angles of the suction cup body 37 can be adjusted to meet the needs of glass 42 at different angles, so that the suction cup body 37 can always be adsorbed directly on the glass 42, and a more solid adsorption force can be provided.

[0030] 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.
