[0011] To further elaborate on the technical means and effects adopted by the present utility model to achieve the intended utility model purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific embodiments, structures, features and their effects of the present utility model as follows.

[0012] Embodiment 1:

[0013] As Figures 1 - 3 shown, the present utility model discloses an automatic tilting oil barrel stacker, which includes a base 1 and support legs 2. Moving wheels are provided below the base 1 and the support legs 2. A vertical support beam 3 is provided on the base 1. A moving frame 4 is slidably connected to the support beam 3. A hydraulic cylinder 16 is provided on the base 1. The telescopic end of the hydraulic cylinder 16 is connected to the moving frame 4. A main shaft 5 is provided on the moving frame 4. Guide protrusions 6 are axially provided on the circumferential surface of the main shaft 5. Two clamping claws 7 are sleeved on the main shaft 5. A first motor 8 is provided on the main shaft 5 near one end of the moving frame 4. The output end of the first motor 8 is connected to a lead screw 9. The lead screw 9 is axially provided along the main shaft 5. Threaded holes are provided on the two clamping claws 7. The lead screw 9 passes through the threaded holes and is in mating connection. The thread directions at both ends of the lead screw 9 are opposite. The two clamping claws 7 are respectively connected to two parts of the lead screw 9 with opposite thread directions; A power mechanism is provided on the moving frame 4, and the power mechanism drives the main shaft 5 to rotate.

[0014] A support beam 3 is provided on the base 1, and the moving frame 4 is slidably connected to the support beam 3. In practice, a slide rail, such as a dovetail-shaped slide rail, can be provided on the support beam 3, and the moving frame 4 is slidably connected in cooperation with the dovetail-shaped slide rail. Its specific structure is the prior art and will not be elaborated here. A power mechanism is provided on the moving frame 4, and the power mechanism drives the main shaft 5 to rotate, so as to realize the flipping of the oil barrel clamped by the gripper 7 and complete the automatic flipping. The main shaft 5 extends outward from the moving frame 4, so two grippers 7 are provided on the main shaft 5, which can realize the clamping of the oil barrel by inserting from the side, or the grippers 7 can be sleeved over the oil barrel from above after being unfolded. One end of the gripper 7 is a connecting part, provided with a connecting hole, and the connecting hole is sleeved on the main shaft 5 to realize the sliding with the main shaft 5. The other end of the gripper 7 is a clamping part, which is in an arc structure, and the arc openings of the two grippers 7 face each other, facilitating the clamping of the oil barrel. Since the main shaft 5 adopts a cylindrical structure, in order to prevent the gripper 7 from rotating relative to the main shaft 5 during flipping, a guiding protrusion 6 is provided on the main shaft 5, and the shape of the connecting hole of the gripper 7 should match the overall shape of the main shaft 5 and the guiding protrusion 6. The gripper 7 and the main shaft 5 can only move and cannot rotate, so they can maintain a stable state during flipping. The movement between the two grippers 7 is controlled by the first motor 8 and the lead screw 9. The first motor 8 is provided on the main shaft 5 and rotates with the main shaft 5, so it does not affect the adjustment of clamping and loosening of the gripper 7 during flipping. The thread directions at both ends of the lead screw 9 are opposite, so when the lead screw 9 rotates, the two grippers 7 approach or separate synchronously respectively, realizing the clamping and loosening of the oil barrel.

[0015] The above solution realizes the clamping of the oil barrel from the side. After the oil barrel is clamped and lifted, it can be flipped downward. When stacking the oil barrels, the oil barrels can be placed horizontally, and the grippers 7 can be taken out from both sides of the oil barrel, with low space requirements, making the oil barrel stacking more efficient and convenient.

[0016] The structure of the power mechanism is as follows: a driven gear 11 is provided on the main shaft 5 near one end of the moving frame 4, a transmission shaft 12 is rotatably provided on the moving frame 4 on the side of the main shaft 5, a driving gear 10 is provided on the rotating shaft, the driving gear 10 meshes with the driven gear 11, a worm wheel 13 is provided on the transmission shaft 12, a worm 14 is provided on the moving frame 4 on the side of the worm wheel, the worm 14 cooperates with the worm wheel, and a second motor 15 is provided on the moving frame 4 at the end of the worm 14, and the second motor 15 is in transmission connection with the worm 14.

[0017] The power mechanism uses the second motor 15 to drive the worm 14 to rotate, and the worm 14 drives the worm wheel 13 to rotate, so that the transmission shaft 12 and the driving gear 10 rotate, and finally the driven gear 11 and the main shaft 5 rotate to realize the flipping of the oil barrel. During the rotation process, the worm wheel 13 and the worm 14 are used for self-locking, and the positioning can be stopped at any time to improve the controllability. Moreover, the flipping angle can be controlled according to actual needs without any restrictions.

[0018] There are four guiding protrusions 6, which are evenly distributed on the circumferential side wall of the main shaft 5.

[0019] Using four guiding protrusions 6, which are evenly distributed on the circumferential side wall of the main shaft 5, makes the force on the clamping claws 7 more stable and improves the moving stability of the clamping claws 7.
