Description

Technical Field

[0001] This utility model belongs to the technical field of ton bag lifting devices, specifically relating to a balancing and anti-swaying device for ton bag lifting. Background Technology

[0002] In lifting operations involving ton bags or bulk bags, traditional lifting equipment typically employs single-point suspension or a simple frame structure. This causes the ton bags to sway violently after lifting due to a shift in the center of gravity, increasing the risk of collisions and potentially leading to sling detachment or even overturning. Existing anti-sway devices mostly constrain the ton bags through fixed limiting structures, but these are difficult to adapt to the sling attachment point positions of ton bags of different sizes and lack active tension adjustment capabilities. The anti-sway effect is significantly reduced, especially when lifting irregularly shaped ton bags, and they lack both balance adjustment and adaptive anti-sway functions.

[0003] A prior art lifting device (publication number CN211004175U) for lifting ton bags addresses the sling adaptation issue through the sliding grooves of the cross-shaped boom and the adjustable distance seat. Dovetail grooves are provided on the four cantilever arms, and the adjustable distance seat is slidable and fixed to threaded through holes by locking bolts. The position of the adjustable distance seat is adjusted to match different ton bag slings. The arc-shaped bottom surface of the groove and the rounded corners of the cantilever arms prevent sling wear. However, this device lacks an active anti-sway mechanism: it only achieves sling position adaptation and does not solve the problem of swaying caused by inertia of the ton bag during lifting. Utility Model Content

[0004] The technical problem solved by this utility model is to overcome the defects in the existing technology and provide a balancing and anti-sway device for lifting ton bags.

[0005] The technical solution adopted in this utility model is as follows:

[0006] This utility model discloses a balancing and anti-sway device for lifting ton bags, comprising a cross-shaped lifting device, which includes two perpendicular booms I and II. The top of the cross-shaped lifting device is provided with lifting lugs and several ton bag hooks, and the bottom is provided with several limiting mechanisms. The lifting lugs cooperate with the lifting equipment, and the ton bag hooks correspond to the positions of the limiting mechanisms. Each limiting mechanism includes a fixed block, and telescopic rods are symmetrically arranged on both sides of the fixed block. The end of the telescopic rod furthest from the fixed block is connected to a limiting buckle.

[0007] The bottom of the cross-shaped lifting device has several screw holes, and the middle of the fixing block has a through hole. The screw holes and the through hole are positioned correspondingly.

[0008] Bolts are installed inside the screw holes and through holes, and washers are provided at the bottom of the fixing blocks and bolts.

[0009] The bottom of the cross-shaped lifting device is equipped with a support rod, which is connected to the center of the bottom of the cross-shaped lifting device. Rib plates I are symmetrically provided between the support rod and boom I and boom II, and rib plates II are symmetrically provided between boom I and boom II.

[0010] The ton bag hooks are evenly installed on the ends of booms I and II away from the lifting lugs by welding. The ton bag hooks are inverted L-shaped.

[0011] The limit buckle consists of a fixed part and a movable part, with the fixed part being fixedly connected to the telescopic rod.

[0012] One end of the fixed part is rotatably connected to the movable part via a locking pin, the other end of the fixed part is provided with a slot, and the other end of the movable part is provided with a buckle that mates with the slot.

[0013] This utility model has the following beneficial effects:

[0014] 1. The cross-shaped lifting device forms a cross-shaped load-bearing frame through the vertically intersecting booms I and II. Combined with the central support rod and the reinforcement of stiffeners I and II, it significantly improves the overall structural rigidity and load distribution uniformity, and suppresses lifting imbalance.

[0015] 2. The telescopic rods symmetrically arranged in the limiting mechanism can extend and retract in both directions. During the hoisting process, they actively tension the ton bag slings, forming an adaptive buffer mechanism that directly counteracts the lateral swaying force and reduces the swing amplitude of the ton bag.

[0016] 3. The inverted L-shaped ton bag hooks are evenly welded and distributed along the boom. With the help of the limiting mechanism, the position of the bolts in the screw holes can be adjusted to achieve precise matching between the sling hanging point and the limiting point, which can cover ton bags of different diameters.

[0017] 4. The limit buckle adopts a slot and buckle locking structure between the rotating movable part and the fixed part, which can be completed by one hand to limit / release the sling, avoiding the risk of manually lifting the ton bag.

[0018] 5. Add washers to the bottom of the bolts to disperse stress concentration at the connection between the fixing block and the lifting device, and extend the service life of the device under frequent lifting conditions. Attached Figure Description

Detailed Implementation

[0023] like Figures 1 to 3 As shown, the present invention provides a balancing and anti-sway device for lifting ton bags, comprising a cross-shaped lifting device 1. The cross-shaped lifting device 1 includes two perpendicular booms I 101 and II 102. The upper part of the cross-shaped lifting device 1 is provided with lifting lugs 2 and several ton bag hooks 3, and the lower part is provided with several limiting mechanisms. The lifting lugs 2 cooperate with the lifting equipment, and the ton bag hooks 3 correspond to the positions of the limiting mechanisms. The limiting mechanism includes a fixing block 4, and telescopic rods 5 are symmetrically provided on both sides of the fixing block 4. The end of the telescopic rod 5 away from the fixing block 4 is connected to a limiting buckle 6.

[0024] The bottom of the cross-shaped lifting device 1 is provided with several screw holes 7, and the middle position of the fixing block 4 is provided with a through hole 401. The screw holes 7 and the through hole 401 are positioned corresponding to each other.

[0025] Bolts 8 are installed inside screw holes 7 and through holes 401, and washers 9 are provided at the bottom of fixing block 4 and bolts 8.

[0026] The bottom of the cross-shaped lifting device 1 is provided with a support rod 10, which is connected to the center position of the bottom of the cross-shaped lifting device 1. The support rod 10 and the boom I 101 and boom II 102 are symmetrically provided with stiffening plates I 11, and the boom I 101 and boom II 102 are symmetrically provided with stiffening plates II 12.

[0027] The ton bag hooks 3 are evenly distributed on the ends of booms I 101 and II 102 away from the lifting lugs 2 by welding. The ton bag hooks 3 are inverted L-shaped.

[0028] The limit buckle 6 includes a fixed part 601 and a movable part 602. The fixed part 601 is fixedly connected to the telescopic rod 5.

[0029] One end of the fixed part 601 is rotatably connected to the movable part 602 via a locking pin 603. The other end of the fixed part 601 is provided with a slot 604, and the other end of the movable part 602 is provided with a buckle 605 that cooperates with the slot 604.

[0030] Specifically, in practice, when hoisting a ton bag, first connect the lifting lug (2) to the lifting equipment and move the cross spreader 1 to the location of the ton bag, and then hang the sling of the ton bag on the ton bag hook 3 on the cross spreader 1.

[0031] Specifically, the limit buckle 6 in the limit mechanism is opened, and the buckle 605 on the movable part 602 is separated from the slot on the fixed part 601. The movable part 602 is rotated around the locking pin 603 so that the movable part 602 and the fixed part 601 are in an open state.

[0032] Specifically, the two sides of the ton bag sling already attached to the cross spreader 1 are respectively placed between the movable part 602 and the fixed part 601, and the buckle 605 is reinserted into the slot 604 for closure and limitation. Finally, the ton bag is hoisted to the designated position by the lifting equipment.

[0033] Specifically, the telescopic rod 5 in the limiting mechanism can extend away from the fixed block 4, so that the limiting buckle 6 can provide a certain support for the ton bag sling and prevent the ton bag from shaking significantly during the hoisting process.

[0034] Specifically, several ton bag hooks 3 are evenly arranged at the ends of boom I 101 and boom II 102 away from the lifting lug 2, so that the cross spreader 1 can adapt to ton bags of different diameters. When the ton bag sling is attached to the ton bag hook 3, the limiting mechanism can be fixed to the bottom of the current ton bag hook 3 by bolts 8.
