[0018] like Figure 1 As shown: A lifting and transferring device for oil storage drums includes a crane hook 1, a clamping device, and a locking device. The locking device is arranged along the clamping device, and the clamping device has connecting rod assemblies symmetrically arranged along the crane hook. Each connecting rod assembly includes a first pull rod 2 and a second pull rod 3. The first end of the first pull rod 2 is hinged to the crane hook 1, and the second end of the first pull rod 2 is hinged to the first end of the second pull rod 3. The middle parts of each second pull rod 3 are hinged together, and the second end of the second pull rod 3 is detachably connected to the oil storage drum. The clamping device adopts a connecting rod structure to meet the lifting requirements of oil drums of different sizes.

[0019] It also includes a locking device; the locking device includes a self-opening hook 5 and a self-opening fixing pin 6; the middle of each second pull rod 3 is rotatably connected by the self-opening fixing pin 6, the bottom of the overhead crane hook 1 is provided with a protrusion, the first end of the self-opening hook 5 is provided with several holes that can be detached from the protrusion, and the second end of the self-opening hook 5 is provided with a hook-shaped part that can be detached from the self-opening fixing pin 6. Before use, the clamping device can be pre-opened to clamp the oil storage tank, and then the locking function is achieved by the cooperation of the self-opening hook 5 and the self-opening fixing pin 6.

[0020] The top of the crane hook has a lifting hole, and the bottom ends have first tie rod mounting points, with a protrusion in the middle of the bottom. The lifting hole facilitates lifting by the crane hook, the first tie rod mounting points are used for hinged connection of the first end of the first tie rod 2, and the protrusion is used for connection with the hole of the self-opening hook 5.

[0021] The second tie rod 3 is a split structure, comprising a straight rod and an arc-shaped bent rod; the straight rod and the arc-shaped bent rod are bolted together. This allows for quick replacement and localized reinforcement, while reducing manufacturing difficulty. In this embodiment, the first end of the straight rod is hinged to the second end of the first tie rod 2, and the middle sections of the two straight rods are rotatably connected by a self-opening fixing pin 6. The second end of the straight rod is hinged to the first end of the arc-shaped bent rod.

[0022] It also includes a contour clamping block 4; the outer side of the contour clamping block 4 is connected to the second pull rod 3, and the inner side of the contour clamping block 4 is attached to the oil storage tank. In this embodiment, the second end of the curved rod is connected to the contour clamping block 4.

[0023] The contour clamp 4 can be designed according to the shape of the oil storage tank to increase the contact area. It is also designed with a rubber pad to increase the coefficient of friction and improve the lifting weight.

[0024] Working principle: When in use, hang the overhead crane hook in the lifting hole of the overhead crane hook 1, lower the overhead crane to lower the clamping device, place the two contoured clamps 4 against the outside of the oil storage tank, and use the self-opening hook 5 and the self-opening fixing pin 6 of the locking device to tighten, slowly raise the overhead crane, and after it is firmly clamped, lift the oil storage tank and transport it to the destination by the overhead crane.
