Description

Technical Field

[0001] This utility model belongs to the field of industrial material handling equipment technology, specifically relating to a ton bag balancer for forklifts. Background Technology

[0002] In existing technology, the inner diameter of the standard ton bag hook is smaller than the distance between the two forks of the forklift, making it impossible to insert simultaneously. When operating with a single fork, the center of gravity offset is greater than 200mm (when the load is 2 tons), which increases the overturning moment (calculation formula: M=G×L). This poses a risk of forklift overturning and violates the forklift safety operating procedures, resulting in safety hazards. Manually assisting in attaching the sling takes 8-10 minutes per bag, reducing efficiency. Using a crane requires hiring a truck crane, which is costly.

[0003] In view of the above factors, a ton bag balancer for forklifts is provided. The central suspension rod is detachably connected to the connecting base. The connecting base and the central suspension rod form an independent suspension end that cooperates with the balancer. The load of the two forks is combined to the center line of the suspension rod through the connecting base, eliminating the eccentricity. Utility Model Content

[0004] The purpose of this utility model is to provide a forklift ton bag balancer to solve the problems mentioned in the background art.

[0005] The purpose of this utility model is achieved through the following technical solution: a ton bag balancer for forklifts, including a mounting base and a balancer detachably connected to the mounting base. The mounting base includes a connecting base, which is welded into a U-shaped cavity by steel structure. A central suspension rod is detachably connected to the connecting base, and a tapered guide head is machined at the end of the central suspension rod.

[0006] The central suspension rod is inserted into the positioning sleeve fixedly installed on the balance hanger, and the positioning sleeve is fixedly provided with an anti-slip layer.

[0007] Furthermore, the connection between the connecting base and the central suspension rod is a plug-in connection that allows for detachment.

[0008] A connection channel is fixedly provided on the vertical end face of the connecting base relative to the central suspension rod, and a positioning hole is fixedly provided on the horizontal end face of the connecting base, with the positioning holes arranged symmetrically.

[0009] Furthermore, the rear end of the central suspension rod is fixedly welded with a connecting end that mates with the positioning hole, and the connecting end is symmetrically provided with positioning channels that mate with the positioning hole.

[0010] Furthermore, the balancing lifting device includes a positioning frame, which is a rectangular frame structure welded from steel. A crossbeam support is fixedly welded to the bottom of the positioning frame, and a lifting end is detachably connected to the crossbeam support. A hook is hinged to the lifting end.

[0011] The crossbeam support extends along the right-angle end of each of the positioning frames toward the positioning frame.

[0012] Furthermore, the crossbeam support is provided with through holes at fixed intervals, and the through holes are connected to the hoisting end by bolts.

[0013] Furthermore, the positioning sleeves are welded at fixed intervals on the end face of the positioning frame, and the length of the positioning sleeves is one-third of the width of the positioning frame.

[0014] Furthermore, the balancing device includes two sets of intersecting positioning ends, which are cylindrical tube structures or square column structures. The two sets of intersecting positioning ends are connected by welding, and each positioning end has a hook-on end.

[0015] The upper part of the positioning end is welded to a support platform via a support rod, and the support platform is a circular or square structure.

[0016] Furthermore, the hook end is a symmetrical arc-shaped plate structure, and the arc-shaped plate structure protrudes from the circumferential surface of the two sets of intersecting positioning ends;

[0017] The arc-shaped plate structures form a suspension space, and the two sets of intersecting positioning ends are designed with a retractable structure.

[0018] Furthermore, the positioning sleeves are welded at fixed intervals on the end face of the support platform, and the diameter or length of the support platform is less than the length of the two sets of intersecting positioning ends.

[0019] A method for applying a ton bag balancer for forklifts includes the following steps;

[0020] Connect the connecting base on the mounting base to the forklift arm and bolt the central suspension rod to the connecting base. In use, connect the central suspension rod to the positioning sleeve fixed on the balance spreader. The anti-slip layer inside the positioning sleeve increases the friction between the central suspension rod and the positioning sleeve to prevent slippage.

[0021] When lifting ton bags, the position of the hook or attachment end on the balance spreader can be adjusted according to the size of the ton bag.

[0022] When lifting ton bags, the balance spreader engages the hook or attachment point on the balance spreader and lifts the bag using a forklift.

[0046] The central suspension rod 4 is inserted into the positioning sleeve 6 fixedly installed on the balance hanger 2. The positioning sleeve 6 is fixedly provided with an anti-slip layer 7, which is a rubber layer.

[0047] In the above embodiments, since the central suspension rod 4 and the balance hanger 2 are connected by a plug-in method, they can be disassembled in use. The connecting base and the central suspension rod can be used independently. In the above embodiments, the double fork load is combined to the center line of the suspension rod through the connecting base to eliminate the eccentricity. The conical head and the hanging mouth (symmetrical hanging mouth) are fitted with a clearance (H9 / d9), and the insertion guide tolerance is ±4mm.

[0048] Example 2:

[0049] Unlike Embodiment 1, a forklift ton bag balancer includes a mounting base 1 and a balancer 2 detachably connected to the mounting base 1. The mounting base 1 includes a connecting base 3, which is welded into a U-shaped cavity by steel structure. A central suspension rod 4 is detachably connected to the connecting base 3, and a tapered guide head 5 is machined at the end of the central suspension rod 4.

[0050] The central suspension rod 4 is inserted into the positioning sleeve 6 fixedly installed on the balance hanger 2. The positioning sleeve 6 is fixedly provided with an anti-slip layer 7, which is a rubber layer.

[0051] To facilitate the lifting of ton bags using a balancing spreader during use, the balancing spreader 2 includes a positioning frame 12. The positioning frame 12 is a rectangular frame structure welded from steel. A crossbeam support 13 is fixedly welded to the bottom of the positioning frame 12. A lifting end 14 is detachably connected to the crossbeam support 13, and a hook 15 is hinged to the lifting end 14.

[0052] The hoisting end consists of two symmetrical plate structures, with upper and lower openings connected to the through hole 16 and hinged to the hook 15.

[0053] The crossbeam support 13 extends along the right-angle end of each of the positioning frames 12 toward the positioning frame 12.

[0054] The crossbeam support is fixed to the positioning frame and the central positioning plate, and the two sides of the central positioning plate are welded to the positioning frame by connecting rods.

[0055] To facilitate the hoisting of ton bags of different sizes during use, through holes 16 are fixedly spaced on the crossbeam support 13. The through holes 16 are connected to the hoisting end 14 by bolts. The crossbeam support is convex in shape with the convex shape facing downwards, and through holes 16 are provided on the extended end of the convex shape.

[0056] The hole 16 is connected to the lifting end 14 by bolts, allowing for disassembly and replacement of the hole position to use ton bags of different sizes.

[0057] To facilitate hoisting in use by cooperating with the central suspension rod 4 through the positioning sleeve, the positioning sleeve 6 is fixedly welded at intervals on the end face of the positioning frame 12, and the length of the positioning sleeve 6 is one-third of the width of the positioning frame 12.

[0058] Example 3:

[0059] Unlike Embodiment 2, in order to facilitate the lifting of ton bags by the balance lifting device in use, another form of the balance lifting device is provided, wherein the balance lifting device 2 includes two sets of intersecting positioning ends 17, wherein the positioning ends 17 are set as cylindrical tube structures or square column structures, the two sets of intersecting positioning ends 17 are connected by welding, and the end of the positioning end 17 is provided with a hook end 18.

[0060] The upper part of the positioning end 17 is welded to the support platform 19 via a support rod. The support platform 19 is circular or square in structure.

[0061] In order to facilitate the attachment and fixing of the ton bag to the hook ears through the hook end in use, the hook end 18 is a symmetrical arc-shaped plate structure, which protrudes from the circumferential surface of the two sets of intersecting positioning ends 17.

[0062] The arc-shaped plate structures form a suspension space, and the two sets of intersecting positioning ends 17 are designed with a telescopic structure.

[0063] The positioning sleeves 6 are welded at fixed intervals on the end face of the support platform 19, and the diameter or length of the support platform 19 is less than the length of the two sets of intersecting positioning ends.

[0064] The aforementioned arc-shaped plate structure forms a suspension space, which fixes the hanging ears of the ton bag in the suspension space during hoisting to achieve the effect of preventing it from falling off. At the same time, depending on the size of different ton bags, the two sets of intersecting positioning ends 17 adopt a telescopic structure.

[0065] Example 4:

[0066] A method for applying a ton bag balancer for forklifts includes the following steps;

[0067] Connect the connecting base 3 on the mounting base 1 to the forklift arm and connect the connecting base 3 to the central suspension rod 4 by bolts. In use, connect the central suspension rod 4 to the positioning sleeve 6 fixed on the balance spreader 2. The anti-slip layer inside the positioning sleeve 6 increases the friction between the central suspension rod 4 and the positioning sleeve 6 to prevent slippage.

[0068] When lifting ton bags, the position of the hook 15 or the attachment end 18 on the balance spreader 2 can be adjusted according to the size of the ton bag.

[0069] When lifting ton bags, the balance spreader 2 connects the hanging bag on the ton bag with the hook 15 or the attachment end 18 on the balance spreader 2 and lifts it with a forklift.
