[0029] The present invention is further described below with reference to specific embodiments. Figure 1 —9:

[0030] A multifunctional lifting equipment includes a boom, which is in the shape of a square. A lifting device is provided on the suspended end of the upper part of the boom, and a mounting portion is provided on the lower part. The lifting device includes a main shaft 1, a secondary shaft 2, a first passive shaft 3 and a second passive shaft 4. The main shaft 1, the secondary shaft 2, the first passive shaft 3 and the second passive shaft 4 are arranged in the front-back direction. The main shaft 1 and the first passive shaft 3, the secondary shaft 2 and the second passive shaft 4 are all driven to rotate in the same direction by a first transmission mechanism and driven to rotate in the opposite direction by a second transmission mechanism. The switching of the actions of the first transmission mechanism and the second transmission mechanism is controlled by a clutch mechanism. The main shaft 1 is driven to rotate by a first driver, and the first driver can be an electric motor or a hydraulic motor 5, etc., which is selected according to actual conditions. When this embodiment is installed on a forklift, the first driver is preferably a hydraulic motor 5. The action of the hydraulic motor 5 is controlled by an operating handle installed in the forklift cab. The hydraulic motor 5 is connected by a coupling or by respectively arranging a connecting sleeve with a sprocket that rotates synchronously with the rotating shaft or the main shaft 1 on the rotating shaft of the hydraulic motor 5 and the main shaft 1, and the two connecting sleeves are connected by a chain to achieve synchronous rotation. The secondary shaft 2 and the main shaft 1 rotate in opposite directions through gear meshing. The gears include a first gear 6 and a second gear 7. On the main shaft 1, one or more first sprockets 8 are arranged at intervals along the axial direction. On the secondary shaft 2, one or more second sprockets 9 are arranged at intervals along the axial direction and the number thereof corresponds to the first sprocket 8. On the first driven shaft 3, one or more third sprockets 10 are arranged at intervals along the axial direction and the number thereof corresponds to the first sprocket 8. On the second driven shaft 4, one or more fourth sprockets 11 are arranged at intervals along the axial direction and the number thereof corresponds to the first sprocket 8. A first chain 12 and a second chain 13 are hung on the first sprocket 8 and the second sprocket 9, respectively; a third chain 14 and a fourth chain 15 are hung on the third sprocket 10 and the fourth sprocket 11, respectively; one end of the first chain 12 and the third chain 14 hangs down automatically from between the third sprocket 10 and the first sprocket 8; one end of the second chain 13 and the fourth chain 15 hangs down automatically from between the second sprocket 10 and the fourth sprocket 11; a lifting ring 17 is provided at the hanging end of the first chain 12 and the second chain 13 through a lifting ring seat 16; a locking bolt 18 is inserted on the lifting ring seat 16; the lower end of the locking bolt 18 is located on one side of the lifting ring 17; a hook 19 is provided at the hanging end of the third chain 14 and the fourth chain 15, and the hook 19 is detachably connected to the upper end of the locking bolt 18.

[0031] When the hook 19 is connected to the upper end of the locking bolt 18, the lifting ring 17 and the locking bolt 18 form an automatic lifting ring.

[0032] A limiting nut is disposed at the upper end of the locking bolt 18 , a connecting buckle is disposed above the limiting nut, a buckle ring 24 is connected to the connecting buckle, and the hook 19 is detachably connected to the buckle ring 24 .

[0033] The specific working principle of automatic lifting is as follows:

[0034] The third chain and the fourth chain are controlled to be in a relaxed state by an operating handle, so that the lock bolt 18 is in a lifting state on the lifting ring 17. The first chain 12 and the third chain 14, the second chain 13 and the fourth chain 15 are raised and lowered synchronously, and the lifting ring 17 is lowered to a suitable position for lifting goods, and the goods are hung. The first chain 12 and the third chain 14, the second chain 13 and the fourth chain 15 are pulled up synchronously to lift them. When the goods are shipped to the destination for stacking, the goods are lowered to the required height for stacking, and then the third chain 14 and the fourth chain 15 are pulled up, and the lock bolt 18 is pulled up to form an automatic lifting release.

[0035] like Figure 1 As shown, a first chain box 20 is provided below the first sprocket 8 and the second sprocket 9 on the boom rod, the other ends of the first chain 12 and the second chain 13 are located in the first chain box 20, a second chain box 21 is provided below the third sprocket 10, the other end of the third chain 14 is located in the second chain box 21, a third chain box 22 is provided below the fourth sprocket 11, and the other end of the fourth chain 15 is located in the third chain box 22. The present invention stores the chains in the corresponding chain boxes, making the whole more tidy, and no interference occurs during use.

[0036] The drooping ends of the first chain 12 and the second chain 13 of the present invention are connected to the eyelet seat 16 through the chain connecting ring 23. When the present invention adds automatic strapping, the eyelet seat and the chain connecting ring 23 are disassembled, and then the strapping hooks are slidably set on the first chain 12 and the second chain 13 respectively, and then the first chain 12 and the second chain 13 are connected through the chain connecting ring 23. When strapping, the two strapping hooks are manually separated and hooked on the sling rings at both ends of the container bag respectively. Affected by the dead weight of the bagged goods, the two strapping hooks automatically move toward the center to achieve tightening during lifting. When tightening, the tying rope that has been tied to the strapping belt ring at one end is pulled around the belt ring at the other end and tied back to the original place, and the strapping is completed.

[0037] When the hook 19 of the present invention is separated from the lock bolt 18, it can be used as a lifting hook or for automatic unpacking. When unpacking automatically, first hang the sling ring of the bundle bag that needs to be automatically unpacked on the automatic unloading ring (composed of the ring 17 and the lock bolt 18). When it is lifted to the set height of the hook 19, the unpacking bag ring on the automatically unpacked bundle bag is hung on the hook 19. The bag drops with the automatic unloading ring. At this time, the weight of the goods will be transferred to the unpacking belt. As the tension of the goods increases, the hook 19 pulls open the bottom-breaking connecting pin on the automatically unpacked bundle bag to achieve suspended bottom-breaking unloading. The height of the unpacking position is determined by the lifting and lowering of the forklift gear frame. The structure of the automatically unpacked bundle bag can be as disclosed in 201520744650.7.

[0038] like Figure 2 ,4 As shown in FIGS. 6 and 7 , the first sprocket 8, the second sprocket 9, the third sprocket 10 and the fourth sprocket 11 are each provided with two in the axial direction, and the corresponding first chain 12, the second chain 13, the third chain 14 and the fourth chain 15 are each provided with two.

[0039] like Figure 4 As shown, the first transmission mechanism includes a main sprocket arranged on the main shaft 1 or the secondary shaft 2 and a secondary sprocket arranged on the first driven shaft 3 or the second driven shaft 4 through a bearing, and the main sprocket and the secondary sprocket are connected to each other through a connecting chain 25.

[0040] The second transmission mechanism includes a main gear 26 disposed on the main shaft 1 or the secondary shaft 2 and a secondary gear 27 disposed on the first driven shaft 3 or the second driven shaft 4 via a bearing. The main gear 26 and the secondary gear 27 can mesh and transmit.

[0041] The first transmission mechanism may also be gear transmission. Since the first transmission mechanism drives the main shaft 1 and the first driven shaft 3, and the secondary shaft 2 and the second driven shaft 4 to rotate in the same direction, three gears need to be set to achieve this.

[0042] Similarly, the second transmission mechanism can also realize the reverse rotation of the main shaft 1 and the first driven shaft 2, and the secondary shaft 2 and the second driven shaft 3 through four gears.

[0043] In this embodiment, the first transmission mechanism includes a structure of a main sprocket, a secondary sprocket, and a chain 25, and the second transmission mechanism includes a structure of a main gear 26 and a secondary gear 27, which has the advantages of simple structure and low cost, and is preferably used.

[0044] The boom rod of the present invention comprises two suspension rods 28 spaced apart from each other on the left and right sides. The suspension rods 28 are square-shaped and connected by a plurality of cross beams 29 . The lifting device is located between the suspended ends of the two suspension rods 28 .

[0045] like Figure 4 , Figure 5 and Figure 6 As shown, the clutch mechanism includes a second driver 30, the movable rod of the second driver 30 is connected to the fork 31, the fork 31 is connected to the clutch slider 32, and the movable rod of the second driver 30 drives the clutch slider 32 to move along the axial direction of the first passive shaft 3 or the second passive shaft 4 to achieve the connection between the main shaft 1 and the secondary sprocket or the secondary gear 27; or the connection between the secondary shaft 2 and the secondary sprocket or the secondary gear 27. The second driver 30 of this embodiment is a hydraulic cylinder, and the action of the hydraulic cylinder is controlled by the operating handle in the forklift cab.

[0046] like Figure 1-Figure 5 , Figure 7-Figure 9As shown, the mounting portion includes a fixing seat 33, a positioning hole 34 is provided on the bottom surface of the fixing seat 33, the fixing seat 33 has no top surface and front side surface, a positioning protrusion 35 is provided at the lower end of the boom rod, the lower end of the boom rod is pushed into the fixing seat 33 from the front side surface of the fixing seat 33 and the positioning protrusion 35 is inserted into the positioning hole 34, and the upper end of the fixing seat 33 is fixedly connected to the boom rod through a pin 36; a T-slot 37 is provided on the rear side surface of the fixing seat 33, and the upper and lower ends of the T-slot 37 are respectively clamped with the fork tooth fixing frame 38 on the forklift.

[0047] During installation, the fixing seat 33 is first installed on the fork tooth fixing frame 38, and then the lower end of the boom rod is pushed into the fixing seat 33 from the front side until the positioning protrusion 35 is inserted into the positioning hole 34 of the fixing seat, and finally the fixing seat 33 and the boom rod are connected and fixed with the pin 36, which is easy to install.

[0048] In addition to being installed on a forklift, the present invention can also be installed on other lifting equipment such as a crane and a gantry truck.
