This application aims to overcome the following shortcomings of existing hoists: the hoist needs to be replaced twice for one wheel turning, the operation is complicated, the production efficiency is extremely low, there are safety hazards in the operation process, and it cannot stay at any angle; but this application still has room for further optimization.

[0004] Another example is the Chinese patent application number: 2019214019887, the invention is named: A rotating mold with automatic clamping, self-locking and loosening, which includes a clamping hand for clamping on an external component, a pair of rolling guide bearings provided at the lower end of the clamping hand, a rotatable connecting rod suspended at the lower end of the clamping hand, a die fixed at the bottom end of the connecting rod with an opening facing downward, and a self-locking clamping claw sleeved on the connecting rod and capable of moving up and down along the connecting rod. The self-locking clamping claw can move up and down along the connecting rod through a disc, driving the lower connecting rod of the clamping arm to open or close, and is suitable for loosening and clamping glass bottles. This application is only specifically applicable to the clamping of glass bottles. Summary of the invention

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0033] The present invention will be further described below in conjunction with the embodiments.

[0034] Example 1

[0035] like Figure 1As shown, the electric flip-claw type intelligent clamp for double-disc circular lifting of this embodiment includes a main frame 100, and lifting ropes 101 are provided on both sides above the main frame 100 for connecting with the lifting equipment. A fixed clamp leg 104 is provided in the middle of the lower part of the main frame 100, and clamp arms 102 that can be relatively close or far away are provided at both ends of the main frame 100. The ends of the clamp arms 102 extend downward to form movable clamp legs 103. The clamp arms 102 on both sides are respectively connected to the clamping power unit 200 and driven by it to move horizontally. A slide rail matching the clamp arm 102 is also provided at the bottom of the main frame 100, and the clamp arm 102 moves horizontally along the direction of the slide rail, thereby ultimately controlling the position change of the movable clamp leg 103. Specifically, a chamber is provided below the main support 100 to cooperate with the clamp arm 102 for its internal movement, and a slide rail is provided at the bottom of the chamber. The clamping power unit 200 drives the clamp arm 102 to move horizontally in the chamber of the main support 100 along the direction of the slide rail, so that the movable clamp leg 103 at its end can achieve position change. A workpiece clamping station is formed between the movable clamp leg 103 and the fixed clamp leg 104 on each side, thereby realizing the clamping and hoisting of double discs. The clamping power unit 200 can control the distance between the movable clamp leg 103 and the fixed clamp leg 104 on each side, so as to meet the operational requirements of hoisting and material collection and subsequent unloading, and can also be applied to the hoisting and clamping requirements of disc workpieces of different sizes.

[0036] In this embodiment, the movable pliers leg 103 and the fixed pliers leg 104 are respectively provided with relatively distributed flaps 105, and the flaps 105 are connected to the flap power unit 300, and the flap power unit 300 is used to drive the flaps 105 to flip and present an open or retracted state. Figure 1 As shown in the figure, both sides of the fixed pliers leg 104 are provided with flaps 105, and the movable pliers leg 103 is provided with flaps 105 on one side opposite to the fixed pliers leg 104, and each clamping station is supported by the flaps 105 on both sides. When not in use, the flaps 105 are retracted and attached to one side of the movable pliers leg 103 and the fixed pliers leg 104, and when in use, the flaps 105 are extended, specifically horizontally, to support and hoist the coiled workpiece from below.

[0037] When this embodiment is used, the movable clamp legs 103 that are movable on both sides can form a double workstation that can be flexibly adjusted. The double discs can be hoisted at the same time, and single-sided hoisting and single-sided unloading operations can be performed according to the actual environment. The entire clamping process can be automatically controlled by the clamping power unit 200 and the flip claw power unit 300, without manual operation, which can effectively improve production efficiency and reduce the labor intensity of personnel.

[0038] Example 2

[0039] The electric flip-claw type intelligent clamp for double-disc round hoisting of this embodiment is basically the same as that of embodiment 1, and further, Figure 2 As shown, the clamping power unit 200 in this embodiment includes a power motor 201 and a transmission screw 207. The transmission screw 207 is arranged in the main support 100 and driven to rotate by the power motor 201. The transmission screw 207 is provided with a matching nut 208. The bottom of the matching nut 208 is connected to the clamp arm 102. The movable clamp leg 103 at the end of the clamp arm 102 extends downward out of the main support 100. The transmission screw 207 drives the clamp arm 102 to move horizontally, that is, drives the movable clamp leg 103 to move horizontally. The power motor 201 and the transmission screw 207 are matched, and the rotational movement of the transmission screw 207 is converted into the horizontal movement of the movable clamp leg 103, thereby realizing the drive adjustment of the movable clamp leg 103. Similarly, this solution can also use various other horizontal displacement driving forces in the industry, which will not be described here.

[0040] Example 3

[0041] The electric flip-claw intelligent clamp for double-disc round hoisting of this embodiment is basically the same as the above embodiment. Furthermore, the clamping power unit 200 of this embodiment includes a power motor 201 and a transmission screw 207. The output end of the power motor 201 is provided with a power gear 202, which meshes with a matching gear 203. A coaxial sprocket 204 is coaxially provided on the matching gear 203. The coaxial sprocket 204 is driven by a transmission chain 205 and a driven sprocket 206. The end of the transmission screw 207 is connected to the middle of the driven sprocket 206 and is driven to rotate. Figure 3 As shown, the power motor 201 drives the transmission screw 207 by cooperating with each other through multiple gears and sprockets.

[0042] Example 4

[0043] The electric flip-claw type intelligent clamp for double-disc round hoisting of this embodiment is basically the same as the above embodiment. Furthermore, in this embodiment, Figure 4 and Figure 5As shown, the flap power unit 300 includes a driving motor 301 and a flap sprocket 304. The driving motor 301 drives the flap sprocket 304 to rotate. The flip movable shaft 305 in the middle of the flap sprocket 304 is connected to the flap 105. Specifically, the output end of the driving motor 301 is provided with a driving sprocket 302, and the driving sprocket 302 is driven by the flap sprocket 304 through a driving chain 303. By driving the flap sprocket 304 to rotate, the flip movable shaft 305 is synchronously driven to rotate, that is, the flipping of the flap 105 is synchronously driven. Further, the mounting end of the flap 105 is embedded in the fixed pliers leg 104 or the movable pliers leg 103, and is hinged to the fixed pliers leg 104 or the movable pliers leg 103 through the flip movable shaft 305. A chamber for accommodating the flap 105 is correspondingly provided in the fixed pliers leg 104 or the movable pliers leg 103. When the flap 105 is driven to flip upward, it retracts into the accommodating chamber. When the flap 105 is driven to flip downward, it opens outward and finally maintains horizontal extension. At this time, it can be used to support the disc workpiece above.

[0044] Example 5

[0045] The electric flap-claw type intelligent clamp for double-disc lifting of the present embodiment is basically the same as the above-mentioned embodiment. Furthermore, in the present embodiment, the upper surface of the flap 105 that is used for contacting the workpiece is paved with a protective layer; the sides of the movable clamp leg 103 and the fixed clamp leg 104 on which the flap 105 is installed are also correspondingly paved with a protective layer. Specifically, a nylon guard plate can be used as the protective layer to prevent damage to the surface of the disc and avoid causing greater wear to the clamp itself.

[0046] The lifting method of the electric flip-claw type intelligent clamp for double-disc round lifting of this embodiment includes the following steps:

[0047] S1. In the initial state, the flap 105 is in a retracted state, and the distance between the movable clamp leg 103 and the fixed clamp leg 104 is adjusted to be appropriate, and the intelligent clamp is lowered to the position of the round workpiece to be hoisted;

[0048] S2, the flap power unit 300 drives the flap 105 to open, so that the flap 105 is supported under the round workpiece, and the clamping power unit 200 drives the movable clamp leg 103 to approach the fixed clamp leg 104 to clamp the workpiece, and the hoisting begins. When hoisting to the final position, the flap power unit 300 can drive the flap 105 to flip and retract downward, and the clamping power unit 200 can drive the movable clamp legs 103 on both sides to move away from the fixed clamp leg 104, thereby completing the unloading of the round coil. This process is repeated in sequence to hoist the round coil.

[0049] The present invention and its embodiments are described schematically above, and the description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by it and designs a structural method and an embodiment similar to the technical solution without creativity without departing from the purpose of the invention, they shall all fall within the protection scope of the present invention.
