Description

Technical Field

[0001] This utility model relates to the field of graphite carbon brick production technology, and in particular to a graphite carbon brick hoisting and clamping device. Background Technology

[0002] In the production of graphite carbon bricks, large-sized graphite carbon bricks are usually transported by hoisting to facilitate operations such as drilling, grooving, and stacking. Utility model patent CN205616446U discloses a double-carbon block clamping device. While it can clamp two carbon blocks at once, the bending angles of the right and left curved clamping arms are fixed. When clamping graphite carbon bricks of varying sizes, the right and left curved clamping arms tend to form an angle with the surface of the graphite carbon bricks, preventing the contacts on the left and right clamping plates from making sufficient contact and causing relative slippage. Furthermore, since the longitudinal length of the right and left curved clamping arms is not adjustable, the clamping points of the right and left curved clamping arms are positioned too high when clamping graphite carbon bricks, resulting in poor clamping stability. Summary of the Invention

[0003] In order to solve the technical problems existing in the above-mentioned technologies, it is necessary to provide a graphite carbon brick lifting and clamping device.

[0004] A graphite carbon brick hoisting and clamping device, including

[0007] The first link has two parts, and the upper ends of the two first links are rotatably connected to the lower end of the connecting end, so that the two first links form an inverted V-shaped structure.

[0008] The second link has two links arranged in an X shape. The upper ends of the two links are rotatably connected to the lower ends of the two first links. The lower end of the second link is integrally provided with a fan-shaped connecting arm, and the connecting arm is provided with adjusting holes in a fan shape.

[0009] The third link, the two ends of which are rotatably connected to the lower ends of the two second links respectively;

[0010] The fourth link includes an upper connecting rod and a lower connecting rod. The upper end of the upper connecting rod is rotatably connected to the connecting arm, and the upper part of the upper connecting rod is connected to the adjustment hole. By assembling with different adjustment holes, the angle between the upper connecting rod and the second connecting rod can be adjusted to accommodate graphite carbon blocks of different widths. The lower connecting rod is slidably inserted into the upper connecting rod. Adjusting the length of the lower connecting rod inserted into the upper connecting rod can control the overall length of the fourth link.

[0011] The clamping assembly is rotatably connected to the lower end of the lower connecting rod. When the connecting end is pulled upward, the included angle between the two first connecting rods decreases, causing the two second connecting rods to synchronously drive the fourth connecting rod to move closer to the center, so that the clamping assembly clamps the carbon brick.

[0012] Preferably, the hook assembly includes a hook and a sealing member; the hook is suspended on the connecting end, and the sealing member has an L-shaped structure. The sealing member is rotatably installed at the opening of the hook. When the sealing member hangs down naturally, the short side of the sealing member can block the opening of the hook. When the long side of the sealing member is rotated upward, the short side of the sealing member rotates upward with the long side of the sealing member, and the opening of the hook opens.

[0013] Preferably, the upper connecting rod has positioning holes evenly distributed along its length, and the lower connecting rod has limiting holes that match the positioning holes. The limiting holes and positioning holes are positioned by a pin.

[0014] Preferably, an adjusting rod is threaded along the length of the outer wall of the upper connecting rod. The lower end of the adjusting rod is rotatably connected to the outer wall of the lower connecting rod. Rotating the adjusting rod can cause the lower connecting rod to slide along the upper connecting rod to adjust the overall length of the fourth connecting rod.

[0015] Preferably, the clamping assembly includes a connecting seat, a base plate, and a rubber pad; the connecting seat is rotatably connected to the lower end of the lower connecting rod, the base plate is fixed on the connecting seat, and the rubber pad is disposed on the side of the base plate away from the connecting seat.

[0016] Preferably, a positioning post is fixed to the lower end of the second connecting rod, and a positioning hook capable of locking the positioning post is rotatably installed on the upper end of the second connecting rod.

[0017] Preferably, the pin end of the lower connecting rod is provided with a cam, and the connecting seat is provided with a stop post to limit the downward rotation limit position of the connecting seat.

[0018] Preferably, the lower end of the connecting end is provided with a hinge seat for connecting the first connecting rod.

[0019] Preferably, a buffer pad layer is fixedly provided on the lower end surface of the third link.

[0020] Preferably, the rubber pad is detachably mounted on the substrate.

[0021] Compared with the prior art, the graphite carbon brick lifting and clamping device provided by this utility model includes a hook assembly, a connecting end, a first connecting rod, a second connecting rod, a third connecting rod, a fourth connecting rod, and a clamping assembly. There are two first connecting rods, the upper ends of which are rotatably connected to the lower end of the connecting end, forming an inverted V-shaped structure. There are also two second connecting rods, arranged in an X-shape, with their upper ends rotatably connected to the lower ends of the two first connecting rods. The lower end of each second connecting rod has an integrally formed fan-shaped connecting arm with fan-shaped adjustment holes. The two ends of the third connecting rod are rotatably connected to the lower ends of the two second connecting rods. The fourth connecting rod includes an upper connecting rod and a lower connecting rod. The upper end of the upper connecting rod is rotatably connected to the connecting arm, and its upper part is connected to the adjustment holes. By assembling with different adjustment holes, the angle between the upper connecting rod and the second connecting rod can be adjusted to accommodate different width dimensions. The graphite carbon block is inserted into the upper connecting rod. Adjusting the length of the lower connecting rod inserted into the upper connecting rod controls the overall length of the fourth connecting rod. The clamping assembly rotates and connects to the lower end of the lower connecting rod. When clamping the graphite carbon block, the connecting end is pulled upward by the lifting device, reducing the angle between the two first connecting rods. This causes the two second connecting rods to synchronously drive the connecting arm to move towards the center, allowing the rubber pad to fit tightly against the opposing surface of the graphite carbon block. Due to gravity, the second connecting rods continuously exert pressure on the rubber pad, ensuring a stable inward pressure from both opposite directions of the graphite carbon block, thus guaranteeing clamping stability. Simultaneously, the rubber pad ensures flexible contact with the graphite carbon block, preventing scratches on its surface, and also increases the contact area, ensuring clamping stability. Adjusting the length of the fourth connecting rod allows for adjustment of the clamping point position, avoiding instability caused by an excessively high clamping point. In use, the angle between the fourth link and the second link can be adjusted to accommodate graphite blocks of different widths, ensuring that the clamping assembly can always maintain full contact with the surface of the graphite brick, thereby increasing the contact area and ensuring the stability of the clamping.

Detailed Implementation

[0028] 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.

[0029] 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.

[0030] Please refer to Figures 1 to 3 This utility model provides a graphite carbon brick hoisting and clamping device, including a hook assembly 30, 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;

[0031] Hook assembly 30 is used to connect lifting equipment;

[0032] 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.

[0033] 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.

[0034] 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.

[0035] The third link 04 has two ends that are rotatably connected to the lower ends of the two second links 03 respectively;

[0036] 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 rotatably connected to the connecting arm 31, and the upper part of the upper connecting rod 91 is connected to the adjustment hole 32. By assembling with different adjustment holes, the angle between the upper connecting rod 91 and the second link 03 can be adjusted to accommodate graphite carbon blocks of different widths. 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.

[0037] 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. During use, the angle between the fourth link 09 and the second link 03 can be adjusted according to the usage requirements to accommodate graphite carbon blocks of different widths; this ensures 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 the clamping.

[0038] In one embodiment, the hook assembly 30 includes a hook 301 and a sealing member 302. The hook 301 is suspended from the connecting end, and the sealing member 302 has an L-shaped structure. The sealing member 302 is rotatably installed at the opening of the hook 301. When the sealing member 302 hangs naturally, its short side can block the opening of the hook 301. When the long side of the sealing member 302 is rotated upward, the short side of the sealing member 302 rotates upward along with the long side, and the opening of the hook 301 opens. This design mechanism can prevent the hook from detaching during suspension, avoiding accidents; at the same time, it facilitates the separation of the hook 301 from the lifting equipment.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] Specifically, the rubber pad 53 is detachably mounted on the base plate 52.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] In one embodiment, the pin end of the lower connecting rod 92 is provided with a cam, and the connecting seat 51 is provided with a stop post. When the connecting seat 51 rotates downward, the cam can prevent the stop post from moving downward, thereby limiting the limit position of the downward rotation of the connecting seat 51, so that the clamping assembly 05 has a suitable angle for placing the charcoal block in its natural state, and realizes the quick clamping of the charcoal block.

[0051] 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.
