Detailed Implementation

[0027] 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.

[0028] 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.

[0029] Please refer to Figures 1 to 3 This utility model provides a clamp applicable to graphite carbon bricks of various sizes, 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;

[0030] Connection end 01 allows for easy connection to lifting devices such as cranes, overhead cranes, and electric / hand hoists, facilitating the lifting and transport of graphite blocks.

[0031] 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.

[0032] There are two second links 03, arranged in an X-shape. The upper ends of the two second links 03 are rotatably connected to the lower ends of the two first links 02. The lower end of the second link 03 is integrally provided with a connecting arm 31. The connecting arm 31 and the second link 03 form a certain angle, which is between 90° and 145°.

[0033] The third link 04 has two ends that are rotatably connected to the lower ends of the two second links 03 respectively;

[0034] The fourth link 09 includes an upper connecting rod 91 and a lower connecting rod 92. The upper end of the upper connecting rod 91 is fixedly connected to the connecting arm 31. The interior of the upper connecting rod 91 is hollow. The lower connecting rod 92 is slidably inserted into the upper connecting rod 91. Adjusting the length of the lower connecting rod 92 inserted into the upper connecting rod 91 can control the overall length of the fourth link 09.

[0035] The clamping assembly 05 is rotatably connected to the lower end of the lower connecting rod 92. When clamping the graphite carbon block, the connecting end 01 is pulled upward by the lifting device, and the included angle between the two first connecting rods 02 becomes smaller. This causes the two second connecting rods 03 to synchronously drive the connecting arm 31 to move closer to the center, so that the rubber pad 53 can be tightly attached to the opposite surface of the graphite carbon block. Relying on the effect of gravity, the second connecting rods 03 can continuously form a compressive force on the rubber pad 53, which can ensure that the rubber pad 53 forms a stable compressive force in the center from two opposite directions of the graphite carbon block, so as to ensure the stability of clamping. At the same time, the rubber pad 53 can ensure flexible contact with the graphite carbon block to prevent scratching the surface of the graphite carbon block, and can also increase the contact area to ensure clamping stability. By adjusting the length of the fourth connecting rod 09, the position of the clamping point can be adjusted to avoid clamping instability caused by the clamping point being too high.

[0036] In one embodiment, the upper connecting rod 91 is provided with positioning holes 93 evenly distributed along the length direction of the upper connecting rod 91, and the lower connecting rod 92 is provided with limiting holes 94 that are adapted to the positioning holes 93. The limiting holes 94 and the positioning holes 93 are positioned by a pin. By fixing the pin in different positioning holes 93 and limiting holes 94, the overall length of the fourth connecting rod 09 can be adjusted.

[0037] Please refer to Figure 4 In one embodiment, an adjusting rod 95 is provided along the length of the outer wall of the upper connecting rod 91. The adjusting rod 95 is installed through two seats 96 fixed on the outer wall of the upper connecting rod 91. The adjusting rod 95 and the seats 96 are connected by threads. The lower end of the adjusting rod 95 is installed through a seat 96 fixed on the outer wall of the lower connecting rod 92. The lower end of the adjusting rod 95 is rotatably connected to the seat 96 fixed on the outer wall of the lower connecting rod 92. When the adjusting rod 95 is rotated, the adjusting rod 95 can drive the lower connecting rod 92 to slide along the upper connecting rod 91 to adjust the overall length of the fourth connecting rod 09.

[0038] 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 lower connecting rod 92. 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 the stability of the clamping. 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 the stability of the clamping.

[0039] Specifically, the rubber pad 53 is detachably mounted on the base plate 52.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] Of course, to better provide a cushioning effect, a mounting hole can be made on the lower end face of the third link 04, and a spring can be fixed in the hole, with the lower end of the spring extending out of the mounting hole and connecting to the buffer pad layer 08. Alternatively, the spring can also be fixed to the lower end face of the third link 04 by a fixing plate, with the lower end of the spring connecting to the buffer pad layer 08.

[0046] 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.

[0047] 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.
