The wire rope is likely to fall off the pulley, affecting the installation of the glass swivel chair. In addition, during the above process, the wire rope will rub against the pulley groove, causing the wire rope to be frequently damaged and need to be repaired and replaced frequently.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Reference Figures 1 to 6The pneumatic balancing hanger for a windshield comprises a pneumatic balancing structure 1, a steel wire rope 2 and a rotating adjustment structure 3. The pneumatic balancing structure 1 is movably assembled on a cross beam, and both ends of the steel wire rope 2 are respectively mounted on the pneumatic balancing structure 1 and the rotating adjustment structure 3. The lower end of the rotating adjustment structure 3 grabs the windshield through a suction cup hanger.
[0026] The crossbeam is movably assembled on the support beam, and the crossbeam can move on the support beam, and can move on the crossbeam in coordination with the pneumatic balancing structure 1, so that the pneumatic balancing structure 1 and the windshield glass suspended thereon can move freely within the range of the support beam.
[0027] The pneumatic balance structure 1 is mainly used to control the stability of the windshield during the lifting and moving process.
[0028] The rotation adjustment structure 3 can deflect the windshield and help ensure the stability of the windshield during movement.
[0029] like Figure 2 and Figure 3 As shown, the pneumatic balancing structure 1 includes a shell 101 and a cylinder mounting plate 102, a cylinder 103 is fixedly mounted on the surface of the cylinder mounting plate 102, a front fixed plate 104 is fixedly mounted on the front end of the cylinder 103, a front movable plate 105 is fixedly mounted on the output end of the cylinder 103, a side plate 106 is welded and assembled on the rear surface of the front fixed plate 104, two side plates 106 are located on the left and right sides of the cylinder 103, a swing pulley assembly 107 is fixedly mounted on the rear side of the outer surface of the side plate 106, a fixed pulley 108 is assembled in the middle of the outer surface of the side plate 106, and the side surfaces of the front movable plate 105 located on the left and right sides of the cylinder 103 are both assembled with movable pulleys 109, and two sets of pulley grooves are arranged on the movable pulley 109, and one end of the wire rope 2 passes through the swing pulley assembly 107, one pulley groove of the movable pulley 109, the fixed pulley 108 and another pulley groove of the movable pulley 109 in sequence, and then is assembled on the side plate 106.
[0030] The operation of the cylinder 103 can drive the front moving plate 105 to move, and then drive the movable pulley 109 to move. Under the control of the cylinder 103, it can ensure that the moving distances of the two movable pulleys 109 are the same, thereby making the lifting and lowering of the windshield more stable, avoiding the situation where the windshield is tilted during the movement and lifting process, and ensuring that the subsequent installation of the windshield proceeds smoothly.
[0031] The upper end of the front fixing plate 104 is bent toward the front side, and the bent portion is used to fix the air pipe connected to the cylinder 103 .
[0032] The positions of the swing pulley assembly 107 and the fixed pulley 108 are fixed.
[0033] Specifically, if Figure 2 and Figure 3As shown, the swing pulley assembly 107 includes a swing mounting frame 1071, a swing shaft 1072 and a swing fixed pulley 1073.

[0034] The swing fixed pulley 1073 can deflect along the swing axis 1072. When the worker moves the windshield in various directions, the swing fixed pulley 1073 can deflect at a certain angle according to the different moving directions, and can automatically adjust the cutting angle between the wire rope 2 and the swing fixed pulley 1073 to ensure that the wire rope 2 is stably located in the pulley groove of the swing fixed pulley 1073, and can prevent the wire rope 2 from slipping out. At the same time, when the swing fixed pulley 1073 is deflected, it can prevent the wire rope 2 from contacting the side wall of the pulley groove of the swing fixed pulley 1073 and generating friction, which greatly alleviates the problem of wear of the wire rope 2 and increases the service life of the wire rope 2.
[0035] Specifically, if Figure 2 and Figure 3 As shown, an air pressure regulating valve 110 is fixedly installed on the lower side of the front surface of the front fixing plate 104 , an air path is connected between the air pressure regulating valve 110 and the cylinder 103 , and a spiral telescopic air pipe 4 is connected to the lower end of the air pressure regulating valve 110 .
[0036] The air pressure regulating valve 110 is used to adjust the air intake volume and speed of the cylinder 103, thereby regulating the operation of the cylinder 103 to make its operation more stable, thereby making the movement and lifting of the windshield more stable.
[0037] There are two spiral telescopic air pipes 4, one is connected to the air pressure regulating valve 110, and the other is connected to the gripper on the suction cup hanger below, both of which play the role of air supply. The spiral telescopic air pipe 4 in the figure is a local simple schematic structure.
[0038] Specifically, if Figure 1 and Figure 2 As shown, a fixing plate 111 is welded and assembled between the upper surface of the cylinder 103 and the rear surface of the front fixing plate 104, a guide wheel 5 is assembled on the fixing plate 111, and the pneumatic balancing structure 1 is moved and assembled on the beam through the guide wheel 5, so that the pneumatic balancing structure 1 can move on the beam and adjust its position.
[0039] Specifically, if Figure 2 and Figure 3 As shown, a cylinder telescopic guide shaft 112 is fixedly mounted on the surface of the cylinder mounting plate 102 , and the cylinder telescopic guide shaft 112 passes through the front moving plate 105 .
[0040] The cylinder telescopic guide shaft 112 serves as a movement guide and auxiliary support for the front movable plate 105 .
[0041] Specifically, if Figure 2 and Figure 3 As shown, a steel wire rope mounting member 113 is fixedly mounted on the outer surface of the side plate 106 , and one end of the steel wire rope 2 is assembled on the steel wire rope mounting member 113 to fix one end of the steel wire rope 2 .
[0042] Specifically, if Figure 4 and Figure 5 As shown, the rotation adjustment structure 3 includes a bearing seat 301, a butterfly head 302 and a balancing connecting rod 303. The butterfly head 302 is fixedly installed on the upper surface of the bearing seat 301, and the balancing connecting rod 303 is assembled on the butterfly head 302. The balancing connecting rod 303 is a V-shaped rod, and both ends of the balancing connecting rod 303 are rotatably equipped with a wire rope fixing head 304. The other end of the wire rope 2 is fixedly installed on the wire rope fixing head 304, and the suction cup hanger is assembled on the lower end of the bearing seat 301.
[0043] The balancing connecting rod 303 in the rotating adjustment structure 3 is parallel to the axis of the pulley, and the wire rope fixing head 304 can deflect at the end of the balancing connecting rod 303. Therefore, it can also deflect when the worker moves the windshield in various directions, thereby reducing the degree of deflection of the upper swinging fixed pulley 1073 and preventing the wire rope 2 from coming out or wearing.
[0044] Specifically, if Figure 4 and Figure 5 As shown, a rotation limit block 305 is fixedly installed on the outer surface of the bearing seat 301, and the rotation limit block 305 is an arc-shaped plate. A fixed limit plate 306 is fixedly installed on the lower surface of the bearing seat 301 through a nut, and one end of the fixed limit plate 306 is bent upward and placed on the outside of the outer surface of the bearing seat 301.
[0045] The bent end of the fixed limiting plate 306 can block the rotating limiting block 305, playing the role of deflection limiting, allowing workers to deflect and adjust the angle of the windshield below, thereby increasing the stability of the deflection adjustment.
[0046] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present invention. As long as these changes do not deviate from the concept of the present invention, they all belong to the protection scope of the present invention.
