[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] like Figure 1-7 As shown, a multifunctional flange hanger comprises:

[0029] The flange fixture 5 is provided with an air bag 53 and a cylinder 54, a piston 541 is slidably provided in the cylinder 54, and a fixing block 56 is fixedly provided on the piston 541;

[0030] The airbag 53 and the cylinder 54 are connected via an air pipe 531 , and the flange fixture 5 moves radially and abuts against the flange edge to compress and deform the airbag 53 .

[0031] Specifically, when the hanger clamps the flange, the flange clamp 5 is driven to move radially, so that the flange clamp 5 abuts against the edge of the flange, thereby preliminarily clamping the flange.

[0032] Further, such as Figure 4 As shown, during the process of the flange clamp 5 abutting against the flange edge, the flange edge squeezes the airbag 53, causing the airbag 53 to be compressed and deformed, thereby squeezing the gas in the airbag 53 into the air pipe 531 and entering the cylinder 54 through the air pipe 531. As the gas continues to enter the cylinder 54, the air pressure in the cylinder 54 increases, thereby pushing the piston 541 to slide in the cylinder 54, thereby driving the fixed block 56 to move toward the flange through the connecting column connected between the piston 541 and the fixed block 56, thereby further fixing the flange through the fixed block 56. No additional driving source is required to drive the piston 541 to move, thereby reducing the manufacturing cost, and the structure is simple and easy to manufacture.

[0033] In the above technology, the flange clamp 5 is driven to move radially, so that the flange clamp 5 is in contact with the flange edge. During the process, the flange edge squeezes the airbag 53, so that the airbag 53 is compressed and deformed, thereby squeezing the gas in the airbag 53 into the air pipe 531 and entering the cylinder 54 through the air pipe 531. As the gas continues to enter the cylinder 54, the air pressure in the cylinder 54 increases, thereby pushing the piston 541 to slide in the cylinder 54, thereby driving the fixing block 56 to move toward the flange through the piston 541, so that the flange is further fixed by the fixing block 56. Compared with the prior art, the flange edge and the upper and lower side surfaces at the flange edge can be synchronously clamped and fixed by the radial movement of the flange clamp 5. Compared with only clamping the flange edge, it is effective to avoid the flange from falling off due to shaking during the movement of the sling, effectively improve the stability of the flange clamping during the movement of the sling, and thus improve the safety performance of the sling.

[0034] As a further embodiment provided by the present invention, the rubber layer 561 is further provided on the fixing block 56 .

[0035] Specifically, a rubber layer 561 is provided on the fixing block 56 to provide buffer protection for the flange, thereby preventing the flange from being worn on the surface of the flange due to friction between the flange and the fixing block 56 during the movement of the lifting device.

[0036] As a further embodiment provided by the present invention, it also includes a first rotating shaft 52 rotatably arranged on the flange clamp 5 , and a rubber sleeve 521 is fixedly arranged on the surface of the first rotating shaft 52 .

[0037] Specifically, during the radial movement of the flange clamp 5, the lower surface of the flange first contacts the rubber sleeve 521 on the first rotating shaft 52. The first rotating shaft 52 is rotatably set in the groove 51 opened on the flange clamp 5, and the first rotating shaft 52 is driven to rotate by the friction between the rubber sleeve 521 and the lower surface of the flange, thereby preventing the lower surface of the flange from directly contacting and rubbing with the flange clamp 5 during the flange clamping process, causing scratches and other damage to the flange surface. After the clamping is completed, the flange is buffered and protected by the joint action of the rubber sleeve 521 and the rubber layer 561, thereby further improving the stability of the flange clamping during the movement of the sling.

[0038] As a further embodiment of the present invention, the second rotating shaft 57 is rotatably arranged on the flange clamp 5 , a wire wheel 571 is fixedly arranged on the surface of the second rotating shaft 57 , a pulling wire 55 is wound around the wire wheel 571 , and the pulling wire 55 is connected to the piston 541 .

[0039] Specifically, the second rotating shaft 57 is connected to the first rotating shaft 52 through a belt 58. During the radial movement of the flange fixture 5, the lower surface of the flange first contacts the rubber sleeve 521 on the first rotating shaft 52, and the friction between the rubber sleeve 521 and the lower surface of the flange drives the first rotating shaft 52 to rotate, thereby driving the second rotating shaft 57 to rotate through the belt 58, thereby driving the wire wheel 571 to rotate and release the wire, thereby releasing the pulling force of the pulling wire 55 on the piston 541, so that when the flange edge squeezes the airbag 53, as the gas continues to enter the cylinder 54, the air pressure in the cylinder 54 increases, thereby pushing the piston 541 to slide in the cylinder 54, thereby driving the fixing block 56 to move toward the flange through the connecting column connected between the piston 541 and the fixing block 56, so that the flange is further fixed by the fixing block 56.

[0040] Furthermore, when the flange is lowered, the flange clamp 5 is driven to move in the opposite direction, and the flange drives the rubber sleeve 521 and the first rotating shaft 52 to rotate in the opposite direction, thereby driving the second rotating shaft 57 to rotate in the opposite direction through the belt 58, thereby driving the wire wheel 571 to reel in the wire, thereby pulling the piston 541 to move in the opposite direction through the pulling wire 55, so that the fixing block 56 releases the clamping of the flange, thereby further squeezing the gas entering the cylinder 54 into the airbag 53 again through the piston 541, so that the airbag 53 recovers and is convenient for the next clamping. The structure is simple and easy to manufacture.

[0041] As a further embodiment of the present invention, the main body 1 is provided with brackets 4 in a circular array, a fixed shaft 41 is fixedly provided on the brackets 4, and the brackets 4 are fixedly connected to the flange clamp 5.

[0042] Specifically, it also includes a turntable 6 rotatably arranged in the body 1, and the turntable 6 is provided with arc grooves 62 in a circumferential array, and the fixed shaft 41 is slidably arranged in the arc groove 62. It also includes a motor 3 fixedly arranged on the body 1, and a gear 31 meshing with the turntable 6 is fixedly arranged at its output end. A lifting ring 2 is arranged on the body 1, and the gear 31 is driven to rotate by starting the motor 3, and the gear 31 drives the turntable 6 to rotate through the gear ring 61 provided on the turntable 6, so that the fixed shaft 41 slides relatively in the arc groove 62 on the turntable 6, and the fixed shaft 41 moves radially under the limiting action of the bracket 4, thereby driving the bracket 4 to move radially, thereby driving the flange clamp 5 to move radially to clamp the flange, thereby achieving the clamping of flanges of different specifications and other disc-shaped parts, thereby enriching the function of the lifting device.

[0043] Working principle: start the motor 3 to rotate, thereby driving the gear 31 to rotate, and the gear 31 drives the turntable 6 to rotate through the gear ring 61 set on the turntable 6, so that the fixed shaft 41 slides relatively in the arc groove 62 on the turntable 6, and the fixed shaft 41 moves radially under the limiting action of the bracket 4, thereby driving the bracket 4 to move radially. During the radial movement of the flange clamp 5, the lower surface of the flange first contacts the rubber sleeve 521 on the first rotating shaft 52, and the friction between the rubber sleeve 521 and the lower surface of the flange drives the first rotating shaft 52 to rotate, thereby driving the second rotating shaft 57 to rotate through the belt 58, thereby driving the wire wheel 571 to rotate and release the wire, thereby releasing the pulling force of the pulling wire 55 on the piston 541, and when the flange edge squeezes the airbag 53, the airbag 53 is compressed and deformed, thereby squeezing the gas in the airbag 53 into the trachea 531 and passing through the trachea 531 enters the cylinder 54. As the gas continues to enter the cylinder 54, the air pressure in the cylinder 54 increases, thereby pushing the piston 541 to slide in the cylinder 54, thereby driving the fixing block 56 to move toward the flange through the connecting column connected between the piston 541 and the fixing block 56, so that the flange is further fixed by the fixing block 56. When the flange is lowered, the flange clamp 5 is driven to move in the opposite direction, and the flange drives the rubber sleeve 521 and the first rotating shaft 52 to rotate in the opposite direction, thereby driving the second rotating shaft 57 to rotate in the opposite direction through the belt 58, thereby driving the wire wheel 571 to reel in the wire, thereby pulling the piston 541 in the opposite direction through the pulling wire 55, so that the fixing block 56 releases the clamping of the flange, thereby further squeezing the gas entering the cylinder 54 into the airbag 53 through the piston 541, so that the airbag 53 recovers and is convenient for the next clamping.

[0044] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
