DETAILED DESCRIPTION

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", "lower", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0027] Please refer to Figures 1 to 3 This utility model provides a graphite carbon brick clamp with adjustable clamping angle, including a connecting end 01, a first connecting rod 02, a second connecting rod 03, a third connecting rod 04, a fourth connecting rod 09, and a clamping assembly 05;

[0028] The connecting end 01 allows for easy connection to lifting equipment such as cranes, overhead cranes, and electric / hand hoists, thus facilitating the lifting and transportation of graphite blocks.

[0029] There are two first connecting rods 02. The upper ends of the two first connecting rods 02 are rotatably connected to the lower end of the connecting end 01, so that the two first connecting rods 02 form an inverted V-shaped structure.

[0030] There are two second connecting rods 03, arranged in an X-shape. The upper ends of the two second connecting rods 03 are rotatably connected to the lower ends of the two first connecting rods 02. The lower end of the second connecting rod 03 is integrally provided with a fan-shaped connecting arm 31. The connecting arm 31 is provided with adjusting holes 32 arranged in a fan shape. Of course, the adjusting holes 32 are divided into upper and lower groups. The hole spacing of the upper adjusting holes is smaller than that of the lower adjusting holes. In this way, the adjustment angle of the upper adjusting holes will be smaller than that of the lower adjusting holes, so that it can be adapted and selected according to actual usage requirements.

[0031] The two ends of the third link 04 are respectively rotatably connected to the lower ends of the two second links 03;

[0032] The upper end of the fourth link 09 is rotatably connected to the upper end of the connecting arm 31, and the upper part of the fourth link 09 is connected to the adjustment hole 32. By assembling with different adjustment holes 32, the angle between the fourth link 09 and the second link 03 can be adjusted to accommodate graphite carbon blocks of different widths; so as to ensure that the clamping assembly 05 can always maintain full contact with the surface of the graphite carbon brick, thereby increasing the contact area and ensuring the stability of clamping.

[0033] In one embodiment, the clamping assembly 05 includes a connecting seat 51, a base plate 52, and a rubber pad 53. The connecting seat 51 is rotatably connected to the lower end of the connecting arm 31. The base plate 52 is fixed on the connecting seat 51, and the rubber pad 53 is disposed on the side of the base plate 52 away from the connecting seat 51. When the connecting end 01 is pulled upward, the included angle between the two first connecting rods 02 decreases, causing the two second connecting rods 03 to synchronously drive the connecting arm 31 to move closer to the center. This allows the rubber pad 53 to be tightly fitted with the opposing surface of the graphite carbon block. Due to gravity, the second connecting rods 03 can continuously exert a compressive force on the rubber pad 53, ensuring that the rubber pad 53 forms a stable compressive force towards the center from two opposing directions of the graphite carbon block, thus ensuring clamping stability. At the same time, the rubber pad 53 can ensure flexible contact with the graphite carbon block, preventing scratches on the surface of the graphite carbon block, and can also increase the contact area, ensuring clamping stability.

[0034] Specifically, the rubber pad 53 is detachably mounted on the base plate 52.

[0035] In one preferred option, the rubber pad 53 can be fixed to the base plate 52 using bolts, which facilitates disassembly and installation; when the rubber pad 53 wears or deforms during use, it can be replaced at any time. Of course, other detachable methods can also be used, such as slot connection, magnetic connection, adhesive connection, etc.

[0036] To prevent the bolt end from wearing down the carbon block, a countersunk hole is provided on the rubber pad 53 so that the bolt end can be inserted. When the rubber pad 53 is installed, it can be ensured that the bolt end will not protrude from the rubber pad 53.

[0037] In one embodiment, a positioning post 06 is fixed to the lower end of the second connecting rod 03, and a positioning hook 07 capable of locking the positioning post 06 is rotatably installed on the upper end of the second connecting rod 03. In use, after the graphite block is hoisted to the predetermined position, the positioning hook 07 can be rotated counterclockwise to pull the positioning post 06, thereby limiting the displacement of the second connecting rod 03. When the lifting device then pulls the clamp upwards, the positions of the two clamping components 05 will be locked, allowing the clamp to quickly disengage from the graphite block while preventing collisions between the clamp and the graphite block during disengagement. Furthermore, when clamping the graphite block again, it is convenient for the clamp to directly clamp the graphite block. At this time, simply rotating the positioning hook 07 clockwise will disengage it from the positioning post 06, and pulling the clamp again will achieve the clamping action.

[0038] In addition, in order to facilitate the connection of the first link 02, a hinge seat 11 for connecting the first link 02 is provided at the lower end of the connecting end 01.

[0039] In one embodiment, a buffer pad 08 is fixedly provided on the lower end surface of the third link 04. When the entire clamp is lowered by the lifting device, the buffer pad 08 can effectively buffer the impact, thereby preventing the third link 04 from causing a hard impact on the graphite block. Of course, the buffer pad 08 can be made of rubber with good elasticity.

[0040] The lower ends of the connecting seat 51 and the connecting arm 31 can be connected by a pin to achieve rotation, and the pin can be fastened by a nut; when the angle of the connecting seat 51 is adjusted to the correct position, it can be locked by the nut.

[0041] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
