[0033] To make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0034] Please refer to Figures 1-9, an oil barrel flipping clamping assembly provided by an embodiment of the present invention includes a bracket 2 that is vertically arranged on a frame 1 and a bracket 3 that is hinged to the bracket 2, and further includes: a semi-circular hoop 4 that is fixedly arranged at one end of the bracket 3, and clamping hoops 5 are hinged to both ends of the semi-circular hoop 4. When the free ends of the two clamping hoops 5 are brought together, they form a hoop ring with the semi-circular hoop 4 for sleeving tightly on the outer side of the oil barrel. The inner diameter of the hoop ring matches the outer diameter of the oil barrel and is smaller than the outer diameter of the convex rib on the outer side of the oil barrel; a clamping edge assembly is arranged at the other end of the bracket 3 for clamping the edge of the discharge end of the oil barrel; a driving assembly is arranged on the bracket 2 for driving the bracket 3 to rotate.

[0035] Specifically, the frame 1 is rectangular and vertically arranged; the bracket 2 is U-shaped and horizontally arranged, and the middle part is connected to the frame 1 in a lifting and movable manner; the bracket 3 is arranged between the two ends of the U-shaped structure of the bracket 2. The bracket 3 includes an arc-shaped rod and a straight rod. The two ends of the arc-shaped rod are respectively hinged to the two ends of the bracket 2, and the arc of the arc-shaped rod is set not to exceed 180°. The straight rod is connected to the middle position of the arc-shaped rod and is perpendicular to the arc-shaped rod in the plane. The semi-circular hoop 4 is arranged parallel to the arc-shaped rod of the bracket 3, and the arc does not exceed 180°; the clamping hoop 5 is arc-shaped, and the free ends of the two clamping hoops 5 are locked and connected through fasteners and are detachable. There is a ring-shaped convex rib on the outer side of the oil barrel, and a raised end edge is arranged at the discharge end; the hoop ring surrounds the lower side of the convex rib in the middle and lower parts of the oil barrel; the clamping edge assembly can be fastened or loosened after clamping the edge of the discharge end of the oil barrel; the driving assembly drives the rotation of the bracket 3 and can stop and hold at any angle. In the actual use of this technical solution, the bracket 2 first descends to an appropriate height to align the bracket 3 with the oil barrel. With the two clamping hoops 5 separated, the semi-circular hoop 4 is clamped to one side of the oil barrel, and the clamping edge assembly corresponds to the upper end of the oil barrel. Then, the two clamping hoops 5 are rotated and brought together and the free ends are locked. Thus, the hoop ring surrounds the middle and lower parts of the oil barrel. At the same time, the clamping edge assembly clamps the edge of the discharge end of the oil barrel. Then, after the bracket 2 rises to an appropriate height, the driving assembly can drive the bracket 3 to rotate, and the bracket 3 drives the oil barrel to rotate and pour. During this process, the discharge end of the oil barrel slowly rotates downward. The hoop ring provides sufficient driving force by supporting the convex rib on the outer wall of the oil barrel, and at the same time, the clamping edge assembly can support the downward discharge end of the oil barrel, thereby avoiding the risk of the oil barrel slipping off.

[0036] Compared with the prior art, an oil barrel flipping clamping assembly proposed by an embodiment of the present invention forms a hoop ring by setting the semi-circular hoop 4 and the clamping hoop 5, which is convenient to be installed on the oil barrel. And through the clamping edge assembly, the edge of the discharge end of the oil barrel is clamped. Thus, when the driving assembly drives the bracket 3 to rotate and the bracket 3 drives the oil barrel to rotate and pour, making the discharge end of the oil barrel slowly rotate downward, the hoop ring provides sufficient driving force by supporting the convex rib on the outer wall of the oil barrel, and at the same time, the clamping edge assembly can support the downward discharge end of the oil barrel, avoiding the risk of the oil barrel slipping off during the pouring process and improving the practicability of the device.

[0037] As a preferred technical solution of this embodiment, the edge clamping assembly includes a blocking block 6 fixedly arranged on the bracket 2. An eagle beak block 7 is hinged on the blocking block 6. A regulating screw 8 is threadedly connected through the eagle beak block 7 in a direction away from the inner side of the bracket 3. One end of the regulating screw 8 abuts against the blocking block 6. Specifically, the blocking block 6 is used to abut against the outer side of the upper edge of the oil barrel. A gap is left between the eagle beak block 7 and the blocking block 6 to clamp the upper edge of the oil barrel, that is, the eagle beak block 7 hooks the inner side of the upper edge of the oil barrel. Then, through screw adjustment of the regulating screw 8, the length of the part abutting against the blocking block 6 is increased, forcing the eagle beak block 7 to rotate, so that the end of the eagle beak block 7 facing the inner side of the bracket 3 cooperates with the blocking block 6 to clamp and limit the upper edge of the oil barrel. Thus, when the oil barrel is subsequently flipped, it can play a role of limiting and supporting.

[0038] As a preferred technical solution of this embodiment, the driving assembly includes a driving rod 9 rotatably arranged in the bracket 2. A worm 10 is coaxially arranged on the driving rod 9. One side of the bracket 3 is coaxially connected with a worm gear 11 meshing with the worm 10. Specifically, the driving rod 9 is horizontally arranged along the end direction of the bracket 2. One end of the driving rod 9 away from the end of the bracket 2 rotates through the bracket 2 and is provided with a crank. The arrangement of the worm 10 and the worm gear 11 enables the driving rod 9 to drive the bracket 3 to rotate in a single direction, and the bracket 3 can stop and remain at any rotation angle.

[0039] A handling forklift includes the above-mentioned oil barrel flipping and clamping assembly, and further includes a frame 1. Legs 12 are arranged at the lower end of the frame 1. Wheels 13 are rotatably connected to the ends of the legs 12. A first linkage assembly is arranged in the frame 1. After the bracket 3 is driven by the driving assembly to rotate to a certain angle, the rotation of the bracket 3 is linked with the rolling of the wheels 13 through the first linkage assembly.

[0040] Specifically, the legs 12 are horizontal and the pointing direction is the same as the pointing direction of the end of the bracket 2; the wheels 13 support the legs 12. In actual use, after the frame 1 moves to a specified position, the oil barrel is rotated to the dumping angle. As the oil in the oil barrel is continuously discharged, the discharge of the oil becomes slower and slower, and the discharge direction gets closer and closer to the forklift direction. Then, when dealing with a narrow dumping range, not only the position of the forklift needs to be adjusted by moving, but also the dumping angle of the oil barrel needs to be increased, which brings trouble to the dumping process and is prone to external leakage. The setting of the first linkage assembly enables the rotation of the bracket 3 and the rolling of the wheels 13 to trigger linkage. Thus, after the driving assembly drives the bracket 3 to rotate to a certain angle for dumping for a period of time, by moving the forklift closer to the dumping range, the bracket 3 can automatically increase the dumping angle through the linkage of the first linkage assembly. Thus, not only the oil discharge speed is ensured, but also the oil discharge range is accurately maintained. The above rotation of the bracket 3 by a certain angle is set to the angle when the oil in the oil barrel can be initially discharged smoothly, usually the angle between the liquid outlet of the oil barrel and the horizontal plane is 0° - 30°.

[0041] As a preferred technical solution of this embodiment, the first linkage assembly includes a chain 14 that is rotatably arranged in a frame 1 and is linked with a roller 13. A guide sleeve 15 is movably connected through the side wall of a bracket 2. A linkage member 16 is movably arranged in the guide sleeve 15. One end of the guide sleeve 15 extends to the inner side surrounded by the chain 14, and a first through groove 17 is opened on the side wall. A latch 18 that movably penetrates the first through groove 17 is arranged on the linkage member 16. A rack 19 is fixedly arranged at one end of the linkage member 16 close to a driving rod 9. A first gear 20 that is matched with the rack 19 is synchronously rotatably arranged on the driving rod 9. The first gear 20 can move axially and meshes with the rack 19 after the driving rod 9 rotates a certain angle. At the same time, the latch 18 is engaged with the chain 14. Specifically, the chain 14 is vertically arranged, and the rolling plane is parallel to the side wall of the bracket 2. The guide sleeve 15 penetrates through the side wall of the bracket 2 close to the chain 14. The guide sleeve 15 can move horizontally, and the moving direction is parallel to the side wall direction of the bracket 2. The guide sleeve 15 is provided with a through hole in the direction perpendicular to the side wall of the bracket 2. One end of the guide sleeve 15 extending to the inner side surrounded by the chain 14 movably penetrates the outer wall of the frame 1, that is, a slot matched with the guide sleeve 15 is arranged inside the frame 1. The linkage member 16 is arranged to move up and down with damping in the guide sleeve 15. The first through groove 17 is opened on the side wall of the guide sleeve 15 facing the side pointed by the end of the bracket 2. The size of the latch 18 is matched with the gap between two adjacent beads of the chain 14. During the process of the driving rod 9 driving the bracket 3 to rotate, the first gear 20 moves axially close to the position corresponding to the rack 19. When the bracket 3 rotates to a certain angle so that the oil barrel can initially pour oil smoothly, the first gear 20 meshes with the rack 19. At the same time, the guide sleeve 15 moves in a linkage manner, driving the latch 18 on the linkage member 16 to engage with the chain 14. Thus, the chain 14 linked with the roller 13 can be linked with the driving assembly through the latch 18, the linkage member 16, the rack 19, the first gear 20, that is, linked with the rotation of the bracket 3.

[0042] As a preferred technical solution of this embodiment, a driving block 21 and a sliding block 22 are movably arranged in the bracket 2. The driving rod 9 is threadedly and penetratingly connected to the driving block 21 and movably penetrates through the sliding block 22. A first elastic member 23 is connected between the driving block 21 and the sliding block 22. The first gear 20 is rotatably connected to the side of the sliding block 22 away from the driving block 21. One end of the guide sleeve 15 close to the driving rod 9 extends within the moving range of the sliding block 22. A second through groove 24 matching the guide sleeve 15 is provided on the side wall of the bracket 2. A second elastic member 25 that hinders the guide sleeve 15 from driving the engaging teeth 18 to engage with the chain 14 is arranged in the second through groove 24. Specifically, the driving block 21 is arranged closer to the rocker end of the driving rod 9 than the sliding block 22; the first elastic member 23 is preferably a spring and is sleeved on the driving rod 9; the driving block 21 and the sliding block 22 only slide axially along the driving rod 9 in the bracket 2; the first gear 20 is connected to the driving rod 9 by a key connection method to make the two rotate synchronously without affecting the axial movement of the first gear 20 on the driving rod 9, and the first gear 20 moves synchronously with the sliding block 22; when the driving rod 9 rotates to drive the bracket 3 to drive the oil barrel to rotate and tilt, the threaded transmission between the driving rod 9 and the driving block 21 causes the driving block 21 to drive the sliding block 22 to approach the guide sleeve 15 and then push the guide sleeve 15. Then, when the driving rod 9 continues to rotate in the same direction under the linkage of the chain 14 and the driving rod 9, the driving block 21 can squeeze the first elastic member 23 to continue approaching the sliding block 22, thereby avoiding interference and maintaining the pushing of the sliding block 22 on the guide sleeve 15 to keep the engaging teeth 18 engaged with the chain 14; the inner wall of one end of the second through groove 24 in the horizontal direction away from the end of the bracket 2 is connected to the guide sleeve 15 through the second elastic member 25. The second elastic member 25 can also be a spring, which keeps pulling the guide sleeve 15 so that when the guide sleeve 15 is not subject to external force, it automatically stays at one end of the second through groove 24 away from the end of the bracket 2, that is, when the guide sleeve 15 is not pushed by the sliding block 22, it causes the engaging teeth 18 to automatically separate from the chain 14.

[0043] As a preferred technical solution of this embodiment, a linkage rod 26 is vertically and movably penetrated through the linkage member 16. Linkage grooves 27 are provided on the upper and lower inner walls of the second through groove 24. The end of the linkage rod 26 movably penetrates through the guide sleeve 15 and is movably connected to the linkage groove 27. The linkage groove 27 includes an inclined section and a straight section. Specifically, in actual use, after the first gear 20 is separated from the rack 19, misalignment easily occurs, affecting subsequent meshing. In the segmented setting of the inclined section and the straight section of the linkage groove 27, the straight section is closer to the end of the bracket 2 than the inclined section, and the end of the inclined section connecting the straight section is closer to the driving rod 9. That is, when the guide sleeve 15 is displaced under the push of the sliding block 22, it drives the linkage member 16 to move. The linkage member 16 drives the linkage rod 26 to first slide with the inclined section of the linkage groove 27. At this time, since the first gear 20 corresponds to the rack 19 when the sliding block 22 starts to push the guide sleeve 15, when the linkage rod 26 slides with the inclined section of the linkage groove 27, the linkage member 16 drives the rack 19 to approach the first gear 20 along the radial direction of the first gear 20, thus ensuring smooth meshing between the two. At the same time, the linkage member 16 drives the engaging teeth 18 to correspond to the gap of the chain 14. After that, when the linkage rod 26 starts to slide with the straight section of the linkage groove 27, the first gear 20 and the rack 19 remain meshed, and the engaging teeth 18 are driven to smoothly engage with the chain 14. Thus, the rolling of the chain 14 can drive the rotation of the driving rod 9.

[0044] In another embodiment proposed by the present invention, a balance platform 28 is rotatably connected to one side of the frame 1 away from the leg 12. Two symmetric universal wheels 29 are installed at the bottom of the balance platform 28. A rocker arm seat 30 is rotatably provided on the frame 1. The rocker arm seat 30 is connected to the balance platform 28 through a shock absorption unit 31. After the roller 13 is linked with the chain 14, the rotation of the rocker arm seat 30 is linked with the chain 14 through a second linkage component. Specifically, the balance platform 28 and the universal wheels 29 support the frame 1, thereby cooperating with the roller 13 to completely support the frame 1; the rocker arm seat 30 includes a turntable and an eccentric rod; a support for connecting the shock absorption unit 31 is provided on the balance platform 28; the shock absorption unit 31 is inclined and is hinged to the rocker arm seat 30 and the upper end of the balance platform 28 at both ends respectively; the setting of the second linkage component also links the rocker arm seat 30 with the chain 14; after the roller 13 is linked with the chain 14, the rolling of the roller 13 can drive the change of the tilting angle of the oil barrel. At the same time, the rocker arm seat 30 is also driven to rotate by the second linkage component, thereby driving the height of the upper end of the shock absorption unit 31 to change reciprocally. Thus, the balance platform 28 swings up and down, and the frame 1 also jolts, so that the oil barrel is jolted to more conveniently and thoroughly pour out the oil, and the dirt in the oil is prevented from blocking the discharge port of the oil barrel.

[0045] As a preferred technical solution of this embodiment, a fixed gear 32 and a moving gear 33 arranged vertically are rotatably connected within the frame 1. The chain 14 is tensioned and connected between the fixed gear 32 and the moving gear 33. The moving gear 33 is linked to the roller 13 through a pulley assembly. The rotating shaft of the moving gear 33 is connected through a universal joint to a second gear 34 that is arranged to move up and down within the frame 1. The rotating shaft of the rocker arm seat 30 is coaxially connected to a third gear 35 that is rotatably arranged within the frame 1. The third gear 35 and the second gear 34 are arranged corresponding to each other vertically. Specifically, the axial directions of the fixed gear 32 and the moving gear 33 are horizontal and are arranged along the side wall of the vertical support 2. The up and down movement of the second gear 34 controls its engagement and separation from the third gear 35, and the tooth profiles of the two have a certain inclination angle. One end of the rotating shaft of the second gear 34 is connected to the rotating shaft of the moving gear 33 through a universal joint, and the other end is connected through another universal joint to a sliding shaft. The sliding shaft is rotatably connected within the frame 1. It can support the rotating shaft of the second gear 34. At the same time, when the rotating shaft of the second gear 34 swings up and down, the sliding shaft can move axially to eliminate interference. During the process of the above-mentioned guide sleeve 15 driving the engaging teeth 18 to engage with the chain 14, the moving range of the guide sleeve 15 can, after the engaging teeth 18 are engaged with the chain 14, continue to move to push the inner side of the chain 14 outwards, causing the chain 14 to be tightened. As a result, the moving gear 33 rises, and the moving gear 33 drives the second gear 34 to rise to engage and transmit with the third gear 35. On the contrary, the second gear 34 and the third gear 35 are separated.

[0046] As a preferred technical solution of this embodiment, the pulley assembly includes a transmission shaft 36 rotatably arranged within the frame 1. One end of the transmission shaft 36 is connected to a roller 13 through a first synchronous belt 37, and the other end of the transmission shaft 36 is connected to the rotating shaft of the moving gear 33 through a second synchronous belt 38. A tension pulley 39 is arranged inside the second synchronous belt 38. The tension pulley 39 is elastically connected to move radially within the frame 1. Specifically, the first synchronous belt 37 is arranged inside the leg 12 for protection; the second synchronous belt 38 is arranged within the frame 1. The second synchronous belt 38 is tightened by the transmission shaft 36, the rotating shaft of the moving gear 33, and the tension pulley 39. The rotating shaft of the tension pulley 39 is rotatably connected to a slider 40 that is elastically slidably arranged within the frame 1. When the chain 14 is not pushed and tightened by the guide sleeve 15, the tension pulley 39 props up one side of the second synchronous belt 38, keeping the moving gear 33 in the lowered position, the second gear 34 and the third gear 35 separated, and enabling the transmission shaft 36 and the moving gear 33 to maintain synchronous transmission.

[0047] Only some exemplary embodiments of the present invention have been described in an illustrative manner above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above-mentioned drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
