These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner. Therefore, they only show the components related to the present utility model. Directions and references (such as up, down, left, right, etc.) can only be used to assist in the description of the features in the drawings. Therefore, the following specific implementation modes are not adopted in a restrictive sense, and the scope of the claimed subject matter is only defined by the appended claims and their equivalent forms.

[0032] Embodiment 1:

[0033] As Figures 1 - 5 shown, a drum clamping and flipping sling includes:

[0034] The gantry 1 includes an integrally formed top beam and columns located at the bottom of the top beam, and a space for clamping and flipping the drum is provided in its central part. Support legs 102 are provided at the bottom of the gantry 1;

[0035] The clamping assembly 2 includes an X-shaped bracing mechanism 201 hinged to the gantry 1, two calipers 203 that can approach or move away from each other, and a link mechanism 202 provided between the X-shaped bracing mechanism 201 and the calipers 203. A power mechanism (not shown in the figure) drives the X-shaped bracing mechanism 201 to stretch or compress to drive the link mechanism 202 to move, and the link mechanism 202 drives the two calipers 203 to approach or move away from each other to clamp or release the drum;

[0036] The flipping assembly 3 includes a rotary drive mechanism 301, a caliper shaft 302 connected between the output end of the rotary drive mechanism 301 and the caliper 203, and a caliper housing 303 sleeved outside the caliper shaft 302 and connected to the link mechanism 202. An installation cavity 103 for installing the flipping assembly 3 is formed by enclosing between the support leg 102 and the gantry 1. The caliper shaft 302 is axially fixed to the caliper housing 303 and can rotate relative to it. Under the action of the rotary drive mechanism 301, the caliper shaft 302 can rotate inside the caliper housing 303, thereby driving the caliper 203 to rotate.

[0037] And the locking assembly 4 includes a locking hook 401 arranged on the scissors brace mechanism 201 and a locking buckle 402 located on the gantry 1 and cooperating with the locking hook 401 to lock or unlock the scissors brace mechanism 201.

[0038] During operation, the power mechanism drives the device to translate to a predetermined position and then continues to drive the device downward until the gantry 1 touches the ground. Then the power mechanism continues to move downward to compress the scissors brace mechanism 201, drives the two calipers 203 to approach each other through the link mechanism 202 to clamp the drum, and at the same time the locking hook 401 snaps into the locking buckle 402 to lock the current clamping state; when flipping is required, the rotary drive mechanism 301 is used to drive the caliper shaft 302 to rotate, and the caliper shaft 302 can drive the caliper 203 and the drum it clamps to rotate synchronously.

[0039] In some examples, the link mechanism 202 includes a push rod 2021 connected to the scissors brace mechanism 201, a first swing arm 2022 connected between the push rod 2021 and the caliper housing 303 and hinged to the gantry 1, and a second swing arm 2023 connected between the caliper housing 303 and the gantry 1; when the scissors brace mechanism 201 is stretched upward, it drives the push rod 2021 to rotate around its hinge point with the gantry 1, and the first swing arm 2022 and the second swing arm 2023 drive the two caliper housings 303 to move away from each other, so that the two calipers 203 move away from each other; when the scissors brace mechanism 201 is compressed downward, the first swing arm 2022 and the second swing arm 2023 drive the two caliper housings 303 and the calipers 203 to approach each other.

[0040] In some examples, the locking hook 401 includes a rod portion 4011 and a locking portion 4012 located at the bottom of the rod portion 4011. The locking buckle 402 includes a sliding-in groove 4021 for the locking portion 4012 to slide into, a locking groove 4022 for locking the locking portion 4012, and a sliding-out groove 4023 for the locking portion 4012 to slide out. The locking groove 4022 is located between the sliding-in groove 4021 and the sliding-out groove 4023 and is in communication with both. When the cross bracing mechanism 201 is compressed downward, the locking portion 4012 enters the locking groove 4022 along the sliding-in groove 4021 to lock the cross bracing mechanism 201. When unlocking is required, the cross bracing mechanism 201 continues to move downward and then upward, and the locking portion 4012 can enter the sliding-out groove 4023 from the locking groove 4022 to disengage from the locking buckle 402, thereby realizing the unlocking of the cross bracing mechanism 201.

[0041] In some examples, there are two sets of the locking assemblies 4, and the two are symmetrically distributed to achieve double-sided locking, so as to improve the locking effect and further improve the safety of the whole device.

[0042] In some examples, the cross bracing mechanism 201 includes two hinged boom groups. One end of each boom group far from its hinge point is hinged with a lever group, and each boom group includes at least two booms 2011, and each lever group includes at least two levers 2012, so as to improve the structural strength of the cross bracing mechanism 201. The portal frame 1 is provided with a through groove 101 for installing the lever group, and the lever group is hinged with the wall of the through groove 101.

[0043] In some examples, the length of the lever 2012 is greater than the length of the boom 2011 to achieve a larger force arm.

[0044] In some examples, the caliper 203 is of an annular structure, and both inner ends thereof are hinged with claw 204, realizing the self-adaptability to the types and sizes of the clamped drums, and improving the versatility and clamping effect of the device.

[0045] In some examples, a rolling bearing 304 is installed between the outer peripheral wall of the caliper shaft 302 and the inner peripheral wall of the caliper housing 303, and a thrust bearing 305 is installed between the end faces of both ends of the caliper shaft 302 and the end faces of both ends of the caliper housing 303, which can make the caliper shaft 302 rotate smoothly inside the caliper housing 303.

[0046] In some examples, several hinge points are provided between the first swing arm 2022 and the push rod 2021 to form different swing amplitudes, so as to realize different clamping forces to clamp drums of different sizes. In this embodiment, there are two hinge points, namely the A hinge point and the B hinge point, thus forming a two-stage adjustment.

[0047] In some examples, a lifting ring 5 is installed at the hinge point of the two suspension rods 2011, facilitating the lifting of the entire device.

[0048] Working principle:

[0049] During operation, the power mechanism drives the device to translate to a predetermined position and then continues to drive the device downward until the gantry 1 touches the bottom. Then, the power mechanism continues to move downward to compress the scissors brace mechanism 201, driving the push rod 2021 to rotate. The push rod 2021 drives two calipers 203 to approach each other through a swing arm and a second swing arm 2023 to clamp the drum. At the same time, the locking portion 4012 of the locking hook 401 slides into the locking groove 4022 from the sliding groove 4021 during the downward movement of the scissors brace mechanism 201, thereby locking the scissors brace mechanism 201.

[0050] When flipping is required, the caliper shaft 302 is driven to rotate by the rotation drive mechanism 301, and the caliper shaft 302 can drive the calipers 203 and the drum they clamp to rotate synchronously.
