[0021] Embodiment 1

[0022] Refer to Figures 1 - 5 , a curtain wall glass installation auxiliary device, including an auxiliary support 1 and a connecting cross bar 2 fixedly installed on one side of the auxiliary support 1. A grabbing component 3 for grabbing the curtain wall glass is provided below the auxiliary support 1. When installing the curtain wall glass, the staff can hold the auxiliary support 1 by hand and use the grabbing component 3 on the auxiliary support 1 to grab the curtain wall glass, avoiding the direct contact between the staff and the curtain wall glass, reducing the probability that the staff's palm may be scratched, and thus improving the protection of the staff;

[0023] The grasping assembly 3 includes a grasping suction cup 31 fixedly installed on one side of the auxiliary bracket 1. An airbag 32 is provided in the grasping suction cup 31, and one end of the airbag 32 extends into the interior of the auxiliary bracket 1. A piston plate 33 is slidably installed in the airbag 32, and the cross-section of the airbag 32 is narrow at the top and wide at the bottom. The edge of the piston plate 33 is in close contact with the upper part of the inner cavity of the airbag 32. A piston rod 34 is fixedly installed on the upper part of the piston plate 33, and the upper part of the piston rod 34 slidably extends to the upper part of the auxiliary bracket 1 and is provided with a lifting rod 37. When grasping the glass curtain wall, the grasping suction cup 31 can be first attached to the glass curtain wall, and then the piston rod 34 can be lifted upward by the lifting rod 37 to drive the piston plate 33 to move upward, thereby increasing the flowing volume of the air in the airbag 32, and then reducing the air pressure in the airbag 32, that is, the air pressure in the grasping suction cup 32. Under the pressure of the external atmospheric pressure, the grasping suction cup 31 will firmly adsorb on the glass curtain wall, facilitating the staff to grasp the glass curtain wall for installation.

[0024] A sealing groove 35 is provided inside the airbag 32, and the cross-section of the sealing groove 35 is diamond-shaped. A sealing ring 36 that is in close contact with the outside of the piston rod 34 is provided in the inner cavity of the sealing groove 35. The sealing ring 36 that is in close contact with the piston rod 34 can isolate the inside and outside of the airbag 32, preventing the airbag 32 from communicating with the outside and affecting the grasping effect. At the same time, because the cross-section of the sealing groove 35 is diamond-shaped, when the piston rod 34 moves, the sealing ring 36 will not move with the piston rod 34 under the restriction of the sealing groove 35, thus ensuring the sealing effect of the sealing ring 36.

[0025] A one-way assembly 38 for restricting the movement of the piston rod 34 is provided in the auxiliary bracket 1. The one-way assembly 38 includes a transmission rod 381 slidably installed inside the auxiliary bracket 1, and a return spring fixedly connected to the auxiliary bracket 1 is provided at one end of the transmission rod 381. A pawl 382 is rotatably installed on the transmission rod 381, and a return torsion spring 383 fixedly connected to the auxiliary bracket 1 is provided on one side of the pawl 382. A ratchet wheel 384 meshing with the pawl 382 is rotatably installed inside the auxiliary bracket 1, and a transmission gear 385 coaxially fixed with the ratchet wheel 384 is rotatably installed inside the auxiliary bracket 1. A transmission rack 386 meshing with the transmission gear 385 is provided on the piston rod 34. The setting of the one-way assembly 38 can prevent the piston rod 34 from moving downward under the action of external force during the grasping process, resulting in the glass curtain wall falling off and other situations. In this embodiment, through the setting of the one-way assembly 38, when the piston rod 34 moves, it will drive the transmission gear 385 to rotate through the transmission rack 386 fixedly connected to it. Since the transmission gear 385 is coaxially fixed with the ratchet wheel 384, when the piston rod 34 moves, the ratchet wheel 384 will be driven to rotate synchronously through a series of mechanical transmissions. Then, when the piston rod 34 moves downward, it will drive the ratchet wheel 384 to engage with the pawl 382, thereby preventing the piston rod 34 from falling, and improving the stability of the grasping assembly 3 for grasping the glass curtain wall.

[0026] Embodiment 2

[0027] Reference Figures 1 - 5 This embodiment is basically the same as the first embodiment, and is more optimized in that the number of auxiliary brackets 1 is two, and an extension component 4 for adjusting the distance between the two auxiliary brackets 1 is provided on the connecting cross bar 2 between the two auxiliary brackets 1, the extension component 4 includes an extension cavity 41 opened inside the connecting cross bar 2, and an extension rod 42 fixedly connected to another connecting cross bar 2 is slidably installed in the extension cavity 41, an extension gear 44 is rotatably installed at one end of the connecting cross bar 2, an extension rack 43 meshing with the extension gear 44 is provided on one side of the connecting cross bar 2, a fastening screw 45 penetrating the connecting cross bar 2 is coaxially fixed on the extension gear 44, and the fastening screw 45 is rotatably connected to the connecting cross bar 2, and a fastening screw 45 is externally threadedly installed with a fastening screw that conflicts with the connecting cross bar 2 Sleeve 46, glass curtain walls of different specifications have different sizes. In order to facilitate the staff to grab the glass curtain wall, in this embodiment, the distance between the two auxiliary brackets 1 can be manually adjusted through the extension component 4, thereby reflecting the practicality of the device. The specific operation is as follows. When adjusting, first loosen the fastening sleeve 46, and then pull the separated auxiliary bracket 1 outward. During the pulling process, the extension rack 43 set on the extension rod 42 will drive the extension gear 44 to rotate through the tooth meshing. When it is adjusted to a suitable position, the fastening sleeve 46 can be tightened to make it conflict with the connecting cross bar 2, so that under the action of the friction between the fastening sleeve 46 and the connecting cross bar 2, the rotation of the extension gear 44 can be limited, thereby realizing the adjustment of the distance between the auxiliary brackets 1.

[0028] How it works

[0029] When installing the glass curtain wall, the worker can hold the auxiliary bracket 1 and use the grabbing assembly 3 on the auxiliary bracket 1 to grab the glass curtain wall, thereby avoiding direct contact between the worker and the glass curtain wall and reducing the probability of scratches on the worker's palms, thereby improving protection for the worker. When grabbing the glass curtain wall, the grabbing suction cup 31 can be first attached to the glass curtain wall, and then the piston rod 34 can be pulled upward by the lifting rod 37 to drive the piston plate 33 to move upward, thereby increasing the flow volume of the air in the airbag 32, and then reducing the air pressure in the airbag 32, that is, the air pressure in the grabbing suction cup 32. Under the pressure of the external atmospheric pressure, the grabbing suction cup 31 will be firmly adsorbed on the glass curtain wall, so that it is convenient for the staff to grab the glass curtain wall for installation. In addition, the sealing ring 36 that fits tightly with the piston rod 34 can isolate the inside and outside of the airbag 32, prevent the airbag 32 from communicating with the outside world, thereby affecting the grabbing effect. At the same time, because the cross-section of the sealing groove 35 is a rhombus, when the piston rod 34 moves, the sealing ring 36 is restricted by the sealing groove 35 and will not move with the movement of the piston rod 34, thereby ensuring the sealing effect of the sealing ring 36. The setting of the one-way component 38 can prevent the piston rod 34 from moving downward under the action of external force during the grabbing process, thereby preventing the glass curtain wall from detaching. In this embodiment, through the setting of the one-way component 38, when the piston rod 34 moves, it will engage the transmission gear 385 with the transmission rack 386 fixed thereto to rotate. Since the transmission gear 385 is coaxially fixed with the ratchet 384, when the piston rod 34 moves, it will drive the ratchet 384 to rotate synchronously through a series of mechanical transmissions. Then, when the piston rod 34 moves downward, it will drive the ratchet 384 to engage with the pawl 382, ​​thereby preventing the piston rod 34 from falling, thereby improving the stability of the grabbing component 3 in grabbing the glass curtain wall. Glass curtain walls of different specifications have different sizes. In order to facilitate the staff to grab the glass curtain walls, in this embodiment, the distance between the two auxiliary brackets 1 can be manually adjusted through the extension component 4, thereby reflecting the practicality of the device. The specific operation is as follows. When adjusting, first loosen the fastening sleeve 46, and then pull the separated auxiliary bracket 1 outward. During the pulling process, the extension rack 43 set on the extension rod 42 will drive the extension gear 44 to rotate through the tooth meshing. When it is adjusted to a suitable position, the fastening sleeve 46 can be tightened to make it conflict with the connecting cross bar 2. Therefore, under the action of the friction force between the fastening sleeve 46 and the connecting cross bar 2, the rotation of the extension gear 44 can be limited, thereby realizing the adjustment of the distance between the auxiliary brackets 1.
