[0002] A pneumatic hoist is a type of air motor that uses compressed air as a medium to drive an air motor, thereby rotating the internal mechanical parts and lifting heavy objects. When the pneumatic hoist and the pneumatic hoist hook are not at the same center point as the heavy object, the pneumatic hoist will cause shaking.

[0003] According to the "Pneumatic Hoist Anti-Sway Structure" with Chinese Patent Publication No. CN219363018U, it mainly describes that by arranging adjustable moving blocks and inclined rods around the hook, it can provide clamping limits when carrying materials, and at the same time fix them by fitting the pads and the card blocks, so that the pneumatic hoist is easily guided when moving horizontally, causing the material to swing and cause the material to fall off. In this process, the pneumatic hoist will not be at the same center point as the heavy object when hanging the heavy object, causing the pneumatic hoist to shake when hanging the heavy object, thereby causing the gas hoist to shake.

[0004] Therefore, an anti-sway structure for a pneumatic hoist is proposed to solve the problem that during the process, the pneumatic hoist will not be at the same center point as the heavy object when hanging the heavy object, causing the pneumatic hoist to shake when hanging the heavy object, thereby causing the gas hoist to shake.

DETAILED DESCRIPTION

[0016] The utility model will be further described below in conjunction with the accompanying drawings.

[0017] Please refer to Figure 1-3The pneumatic hoist anti-sway structure shown includes a connecting plate 1, a hook 2 is rotatably connected to the connecting plate 1, a fixing ring 3 is sleeved on the hook 2, and a support plate 4 is fixedly connected to the bottom end of the fixing ring 3. By setting the support plate 4 and setting four auxiliary ropes 7, the stability of the storage frame 5 can be improved. The bottom end of the support plate 4 is provided with a storage frame 5, the hook 2 is connected to the storage frame 5, the bottom end of the support plate 4 and the upper end of the storage frame 5 are fixedly connected with connecting rings 6, and auxiliary ropes 7 are fixedly connected between the opposite connecting rings 6. Fixed sleeves 8 are fixedly connected to the four sides of the bottom end of the connecting plate 1, and air hole areas 11 are evenly opened on the upper end of the fixing sleeve 8. A support rod 9 is inserted at the bottom end of the fixing sleeve 8, and a piston 10 is fixedly connected to the upper end of the support rod 9. When one side is under force, the first spring 14 will be forced to expand. At this time, the upper end of the support rod 9 and the piston 10 move upward, squeezing the upper space of the fixed sleeve 8, and allowing the gas to overflow from the pore area 11, so that the air overflows and provides a shaking buffer between the hook 2 and the storage frame 5 that are not on the same center line. The bottom end of the support rod 9 is fixedly connected to the limit block 12. The support rod 9 is located on the bottom side of the support plate 4 and is sleeved with a second spring 18. The second spring 18 provides a reverse force and can provide a buffer. One end of the second spring 18 is fixedly connected to the limit block 12. The limit block 12 is penetrated by a cable groove 13. The limit block 12 is located on one side of the cable groove 13 and is provided with a cable inlet 19. The cable inlet 19 facilitates the connection of the limit block 12 with the auxiliary rope 7.

[0018] Among them, the first spring 14 is sleeved on the upper side of the support rod 9, and the piston 10 is fixedly connected to the first spring 14. The first spring 14 is in contact with the fixed sleeve 8. By setting the first spring 14 and the piston 10, in cooperation with the fixed sleeve 8, the buffering effect can be improved, so that the storage frame 5 can quickly reduce the shaking after being subjected to force.

[0019] Among them, the pore area 11 corresponds to the retaining ring 15, and the retaining ring 15 is threadedly connected to the fixing sleeve 8. By setting the retaining ring 15 to rotate, the pore area 11 is driven to shrink, reducing the air overflow pressure, facilitating the provision of reverse pressure, and achieving the effect of rapid part shaking.

[0020] Among them, the hook 2 is in contact with the spring rod 16, and two spring rods 16 are provided. The spring rods 16 are fixedly connected to both sides of the bottom end of the connecting plate 1. By setting the spring rods 16, the hook 2 can be limited, which is convenient for improving the stability of the hook 2 and reducing shaking.

[0021] Among them, the auxiliary rope 7 is in contact with the tie wheel 17, the tie wheel 17 is rotated to connect the limit block 12, and the tie wheel 17 is located in the tie groove 13. By setting the tie wheel 17, the auxiliary rope 7 can be pulled by the tie wheel 17, thereby reducing the friction between the limit block 12 and the auxiliary rope 7.

[0022] Working principle: connect the fixing ring 3 with the hook 2, and use the storage frame 5 with auxiliary ropes 7 and the support plate 4 to carry heavy objects. Four auxiliary ropes 7 are provided between the storage frame 5 and the support plate 4 to provide auxiliary support, thereby improving the movement stability of the storage frame 5, and providing stable support for the auxiliary ropes 7 through the cable pulley 17. At this time, the auxiliary ropes 7 are pulled up by the cable pulley 17 to provide multi-point support, further improving the stability of the storage frame 5. When the center points of the storage frame 5 and the hook 2 of the pneumatic hoist are not on the same center line, one of the four support rods 9 will shake when subjected to force, and under the action of the piston 10, it squeezes the air on the upper side of the fixing sleeve 8 and applies pressure, thereby providing a buffering effect, reducing the shaking of the storage frame 5, thereby simultaneously reducing the shaking of the chain and the hook 2, and then reducing the shaking of the pneumatic hoist.

It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
