[0041] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0042] See Figures 1 to 3 As shown;

[0043] This embodiment discloses a clamping and flipping lifting device, which includes:

[0044] The clamping arm assembly has a lifting part 3 at its upper end, and the lifting device cooperates with external lifting equipment through the lifting part 3;

[0045] A cross shaft seat 4 is disposed at the lower part of the clamping arm assembly, and the cross shaft seat 4 has a drive shaft 401; and

[0046] A rotary clamping head 501 is connected to a drive shaft 401 of a cross shaft seat 4, and a power source connected to the drive shaft 401 drives the rotary clamping head 501 to rotate through the drive shaft 401.

[0047] The rotary clamp head 501 is provided with a clamping structure that cooperates with the object being clamped. The rotary clamp head 501 drives the object being clamped to rotate through the clamping structure.

[0048] Specifically, this embodiment discloses a lifting device suitable for clamping and flipping carbon blocks; firstly, a cross shaft seat 4 is set at the position where the clamping arm assembly cooperates with the carbon block 10, and a power source can drive the rotating clamp head 501 inside the clamping arm assembly to rotate through the cross shaft seat 4, thereby causing the carbon block 10 clamped and fixed by the clamping arm assembly to flip to a specified angle.

[0049] Preferably, the clamping arm assembly of this embodiment includes a clamping arm 2 and a pull arm 1;

[0050] The clamping arm 2 is divided into a vertical clamping arm 201 extending in the vertical direction and an inclined clamping arm 202 formed at the upper end of the vertical clamping arm 201;

[0051] The space between the two vertical clamping arms 201 is the clamping space and rotation space for the object being clamped;

[0052] Two inclined clamping arms 202 are arranged crosswise and rotatably connected by a pin 601;

[0053] The pull arm 1 is rotatably connected to the end of the corresponding inclined clamp arm 202 via the clamp arm connecting rod 602.

[0054] First, this embodiment further defines the composition of the clamping arm assembly, which is divided into a lower clamping arm 2 and an upper pull arm 1. In this embodiment, the clamping arm 2 is integrally formed with a vertical clamping arm 201 and an inclined clamping arm 202. The inclined clamping arm 202 cooperates with the upper pull arm 1 to form a scissor structure. The scissor structure is driven to open and close by the vertical movement of the lifting part 3, thereby realizing the opening and closing of the clamping arm assembly and acting on the carbon block 10 to form a clamping and fixing state.

[0055] Preferably, in this embodiment, the lifting section 3 is located at the connection point of the two lifting arms 1. Specifically, the lifting section 3 in this embodiment is assembled with the clamping arm assembly using a conventional hook release device 301, which ensures that the clamp is safely and stably attached to the lifting equipment. Furthermore, during the lifting process, the hook release device 301 allows the operator to easily connect or disconnect the clamp from the lifting equipment, ensuring operational safety and efficiency. Additionally, in this embodiment, a clamping arm bearing pad 302 is provided at the connection point between the hook release device 301 and the clamping arm assembly.

[0056] Preferably, in this embodiment, the cross shaft seat 4 is located near the lower end of the vertical clamping arm 201; the rotating clamp head 501 is located on one side of the inner wall of the vertical clamping arm 201.

[0057] This embodiment uses carbon block 10 as the object being clamped for further explanation and illustration.

[0058] Preferably, in this embodiment, one end of the clamping structure is connected to the rotating clamping head 501 on the corresponding side, and the other end of the clamping structure is engaged with the front surface of the carbon block 10.

[0059] The clamping structure in this embodiment includes a first extension rod 502 connected to the rotating clamp head 501, the first extension rod 502 extending toward the front side of the carbon block 10; and a second extension rod 503 perpendicular to the first extension rod 502, the second extension rod 503 extending toward the center of the carbon block 10.

[0060] Based on the structure of the carbon block 10, this embodiment further defines the structure of the clamping structure and the cooperation structure between the clamping structure and the carbon block 10. Specifically, the surface of the carbon block 10 in this embodiment has a carbon block protrusion 11.

[0061] The second extension rod 503 extends to the surface of the carbon block protrusion 11, and the end of the second extension rod 503 is connected to a contact plate 504 that abuts against the surface of the carbon block protrusion 11. A clamping rod 505 protruding toward the front side of the carbon block 10 is provided at the connection between the second extension rod 503 and the contact plate 504.

[0062] In this embodiment, the clamping structure abuts against the surface of the carbon block 10 through the clamping rod 505 and the contact plate 504, with the clamping rod 505 abutting against the contact plate 504 to contact the surface of the carbon block 10.

[0063] In order to provide a certain rotational limiting function, in this embodiment, a limiting rod (not shown) of a certain length can be installed on the cross shaft seat 4 on the clamping arm 2 on the side relative to the power source. The end of the limiting rod is flush with the end of the carbon block 10 when it is clamped and fixed. In this way, during rotation, the limiting rod can be used to determine whether there is an object that interferes with the flipping. When the limiting rod touches other objects, it means that the carbon block 10 cannot continue to flip and needs to be checked in time.

[0064] Secondly, as an extended implementation of this embodiment, this embodiment may not have a power source. That is, after clamping and fixing the carbon block 10, the carbon block 10 can achieve the effect of flipping by its own gravity. When flipping by its own gravity, an eccentric clamping method is required to clamp the carbon block.

[0065] To improve structural strength, the vertical clamping arm 201 in this embodiment is provided with reinforcing ribs 203. The reinforcing ribs 203 in this embodiment are reinforcing components of the clamp, increasing the overall rigidity and strength of the clamp, which can improve the stability and durability of the clamp when clamping and flipping heavy objects, and prevent the clamp from deforming or being damaged due to excessive force.

[0066] In the above technical solution, the clamping and flipping clamping lifting device provided by this utility model has the following beneficial effects:

[0067] The clamping and lifting device of this utility model, through the design of the linkage mechanism and the rotating clamping head 501, can achieve clamping and flipping functions by means of electric, pneumatic, hydraulic or no external power but only by the weight of the clamped object. It is suitable for various occasions that require lifting and flipping operations, improving work efficiency and safety.

[0068] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above 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.
