It belongs to the customized application of an industrial overhead crane bridge crane. In high-energy-consuming and large-scale industries such as electrolytic aluminum, the anode carbon block stacking overhead crane is a key equipment for realizing automated upgrading, directly affecting production efficiency and cost control.

[0003] The clamps used in existing stacking overhead cranes have a complex structure. In the case of long-term operation, the risk of component problems is relatively high, and both the production cost and the maintenance cost are relatively high. Moreover, each group of clamps is uniformly controlled and cannot be adjusted according to the actual size of a single carbon block, affecting the carbon block stacking efficiency.

[0004] Therefore, this application provides a carbon block clamp for a stacker crane to meet the requirements. Content of the Utility Model

[0005] The purpose of this application is to provide a carbon block clamp for a stacker crane, simplify the clamp structure, improve the structural stability of the clamp, and reduce the production and maintenance costs.

[0006] To achieve the above purpose, this application provides the following technical solution. A carbon block clamp for a stacker crane includes:

[0007] An upper beam frame. A pulley block, a winding motor, and a winding shaft are provided at the top of the upper beam frame. The pulley block is used to connect the lifting mechanism of the crane to achieve the lifting effect of the upper beam frame. The winding motor drives the winding shaft to be rotatably connected to the upper beam frame. A grouping frame is provided on the upper beam frame. There are multiple groups of the grouping frames and they are evenly arranged along the axis direction of the winding shaft. Upper connecting rods are symmetrically hinged at both ends of the grouping frame. Steel ropes are wound on the winding shaft. There are multiple groups of the steel ropes and they match the grouping frames. The free end of each group of steel ropes passes through the middle of the grouping frame below it.

[0008] A lower beam frame. The lower beam frame and the upper beam frame are both horizontally arranged. A guide cylinder is provided in the middle of the lower beam frame. A sliding column is connected to the bottom end of the steel rope. The sliding column is slidably connected in the guide cylinder and the top of the sliding column can abut against the inner top of the guide cylinder, which can be used to control the lifting of the grouping frame. A clamp structure is provided on the lower beam frame. The clamp structure is hinged to the upper connecting rod, and the clamp structure is linked with the lifting of the lower beam frame. The clamp structure is used to clamp the carbon block.

[0009] Preferably, the fixture structure includes a lower connecting rod, a short handle, clamping arms and clamping plates. There are two groups of clamping arms, which are symmetrically arranged on both sides of the guide cylinder. Each clamping arm has a horizontal section and a vertical section. The two ends of the horizontal section of the clamping arm are hinged to the lower beam frame through the lower connecting rod and the short handle, and the clamping arm always remains horizontal. The lower connecting rod is located outside the short handle. The top end of the lower connecting rod is hinged to the end of the upper connecting rod. Clamping plates are provided on the opposite sides of the vertical sections of the two groups of clamping arms.

[0010] Preferably, the lower part of the vertical section of the clamping arm is hinged to the clamping plate. The bottom end of the clamping arm is provided with a limiting block, which is used to support the clamping plate so that the clamping plate maintains an inclination angle in the non-clamping state to prevent the clamping plate from colliding with the carbon block when falling. Anti-slip pads are provided on the opposite sides of the two groups of clamping plates to increase the friction force during clamping and enhance the stability of clamping the carbon block.

[0011] Preferably, the side beams parallel to the winding shaft on the upper beam frame are I-beams. There are two groups of side beams, which are symmetrically arranged. A connecting beam and a grouping frame are connected between the two groups of side beams. All the grouping frames are on the same horizontal plane. The connecting beam is located below the grouping frame. There are multiple groups of connecting beams, which are symmetrically arranged.

[0012] Preferably, the lower beam frame is provided with lower positioning columns and upper positioning columns. There are multiple groups of lower positioning columns and upper positioning columns, which are symmetrically arranged. The bottom end of the lower positioning column abuts against the carbon block, and the top end of the upper positioning column abuts against the bottom surface of the upper beam frame. The lower positioning column can be used to position the height of the lower beam frame on the carbon block, and the upper positioning column can be used to position the distance between the lower beam frame and the upper beam frame.

[0013] Preferably, the winding shaft is composed of multiple short shafts. The winding motor is located in the middle of the upper beam frame. The winding motor is connected to the short shafts on the left and right through a speed reducer. Adjacent short shafts are connected by couplings. This design aims to utilize existing shaft components to reduce production costs.

[0014] In summary, the technical effects and advantages of the present utility model are as follows:

[0015] The carbon block clamp for the stacker crane is composed of an upper beam frame and a lower beam frame. The winding motor drives the winding shaft to rotate, enabling multiple groups of steel ropes to be wound and released, realizing the lifting and lowering of the lower beam frame, and then driving multiple groups of clamp structures to precisely clamp the carbon blocks. Specifically, when the winding motor drives the winding shaft to rotate, it drives multiple groups of steel ropes to wind upward or release downward. The free ends of the steel ropes slide up and down through the sliding columns in the guide cylinders, thereby adjusting the position of the lower beam frame. The clamp structures on the lower beam frame are linked with the grouping frame through the articulated upper connecting rods. As the distance between the lower beam frame and the upper beam frame increases or decreases, the clamp structures are synchronously clamped or loosened. When the upper beam frame is lifted by the crane, the clamp structures on the lower beam frame can firmly clamp the carbon blocks. The structure is simple, the clamping is firm, which improves the stability and reliability of the clamp, reduces the risk of problems with long-term operating components, lowers the production cost and maintenance cost, and significantly improves the automation level and production efficiency of electrolytic aluminum production.

[0016] In the present utility model, by lifting and lowering the lower beam frame, changing the distance between the lower beam frame and the upper beam frame, and utilizing the self-weight of the lower beam frame, the linkage between the upper connecting rod and the lower connecting rod is achieved, thereby driving the clamping arm to move and enabling the clamping plate to clamp the carbon block. This design realizes the self-adaptive clamping effect through the mechanical structure, meets the actual production requirements for clamping carbon blocks with dimensional deviations, and can improve the stability and efficiency of carbon block clamping and movement.

[0027] Embodiment: Refer to Figures 1-7 A carbon block clamp for a stacker crane shown in the figure, which includes an upper beam frame 1 and a lower beam frame 2.

[0028] Both the lower beam frame 2 and the upper beam frame 1 are horizontally arranged. A guide cylinder 22 is provided in the middle of the lower beam frame 2.

The clamp structure is used to clamp the carbon block 9.

[0029] As an implementation manner in this embodiment, as shown in Figures 3 to 6As shown in the figure, the fixture structure includes a lower connecting rod 3, a short handle 4, a clamping arm 5 and a clamping plate 6. There are two sets of clamping arms 5, which are symmetrically arranged on both sides of the guide cylinder 22. The clamping arm 5 has a horizontal section and a vertical section. The two ends of the horizontal section of the clamping arm 5 are hinged to the lower beam frame 2 through the lower connecting rod 3 and the short handle 4, and the clamping arm 5 always remains horizontal. The lower connecting rod 3 is located outside the short handle 4. The top end of the lower connecting rod 3 is hinged to the end of the upper connecting rod 14. Clamping plates 6 are provided on the opposite sides of the vertical sections of the two sets of clamping arms 5.

[0030] As an implementation manner in this embodiment, to improve the clamping effect of the clamping plate 6, as Figure 5 , Figure 6 shown, the lower part of the vertical section of the clamping arm 5 is hinged to the clamping plate 6. The bottom end of the clamping arm 5 is provided with a limit block 50, and the limit block 50 is used to support the clamping plate 6. Anti-slip pads 60 are provided on the opposite sides of the two sets of clamping plates 6.

[0031] As an implementation manner in this embodiment, as Figure 1 , Figure 3 , Figure 6 shown, the side beams parallel to the winding shaft 12 on the upper beam frame 1 are I-beams. There are two sets of side beams and they are symmetrically arranged. A connecting beam 102 and a grouping frame 101 are connected between the two sets of side beams. All the grouping frames 101 are on the same horizontal plane. The connecting beam 102 is located below the grouping frame 101. There are multiple sets of connecting beams 102 and they are symmetrically arranged.

[0032] As an implementation manner in this embodiment, to facilitate the height positioning of the lower beam frame 2, as Figure 3 , Figure 5 , Figure 6 shown, the lower beam frame 2 is provided with lower positioning columns 20 and upper positioning columns 21. There are multiple sets of lower positioning columns 20 and upper positioning columns 21 and they are symmetrically arranged. The bottom end of the lower positioning column 20 abuts against the carbon block 9, and the top end of the upper positioning column 21 abuts against the bottom surface of the upper beam frame 1.

[0033] As an implementation manner in this embodiment, to facilitate production and installation, as Figure 2 , Figure 7 shown, the winding shaft 12 is composed of four short shafts. The winding motor 11 is located in the middle of the upper beam frame 1. The winding motor 11 is connected to the short shafts on the left and right through a speed reducer, and adjacent short shafts are connected through a coupling.

[0034] The working principle of this utility model: The upper beam frame 1 is connected to the hoisting mechanism of the crane through the pulley block 10. When the carbon block 9 is not clamped, the wire reel 12 winds up the steel wire 13. The steel wire 13 hoists the guide cylinder 22 through the sliding column 15, making the distance between the lower beam frame 2 and the upper beam frame 1 the shortest. The upper positioning column 21 abuts against the upper beam frame 1 to ensure that the distance between the lower beam frame 2 and the upper beam frame 1 meets the installation space requirements of the upper connecting rod 14 and the lower connecting rod 3. At this time, the included angle between the upper connecting rod 14 and the lower connecting rod 3 is the smallest, so that the lower beam frame 2 is located at the outer side position through the lower connecting rod 3. The two groups of lower beam frames 2 are kept open. The clamping plate 6 is turned downward under the influence of gravity and is blocked by the limiting block 50, so that the clamping plate 6 can maintain a certain inclination angle; when clamping the carbon block 9, the crane moves the upper beam frame 1 above the carbon block 9 and makes the position of the lower beam frame 2 correspond to each group of carbon blocks 9. Then the crane lowers the upper beam frame 1, driving the lower beam frame 2 to fall. The lower positioning column 20 supports on the carbon block 9, making the lower beam frame 2 fall on the carbon block 9 and leaving space for the movement of the clamping arm 5. At this time, the clamping plate 6 is located at both ends of the carbon block 9. Then, the carbon block 9 is clamped and hoisted. The crane hoists the upper beam frame 1. At the same time, the winding motor 11 rotates in the reverse direction, driving the wire reel 12 to rotate in the reverse direction and releasing the steel wire 13 wound on it. When the releasing speed of the steel wire 13 is not less than the hoisting speed of the upper beam frame 1, the position of the sliding column 15 in the guide cylinder 22 remains unchanged or even drops. The upper beam frame 1 rises upward, while the lower beam frame 2 remains stationary on the carbon block 9 due to its own weight. At this time, due to the increase in the distance between the upper beam frame 1 and the lower beam frame 2, the included angle between the upper connecting rod 14 and the lower connecting rod 3 increases, driving the lower connecting rod 3 to flip and driving the clamping arm 5 to move towards the middle. During this process, the short handle 4 and the lower connecting rod 3 can keep the horizontal section of the clamping arm 5 horizontal. As the clamping arm 5 moves, the clamping plate 6 contacts the carbon block 9, and as the upper beam frame 1 rises, the clamping plate 6 clamps the carbon block 9. The anti-slip pad 60 can enhance the friction during clamping. Then the position of the clamping plate 6 is fixed after clamping. Therefore, the included angle between the lower connecting rod 3 and the lower beam frame 2 is fixed, making the angle between the upper connecting rod 14 and the lower connecting rod 3 fixed, and the upper connecting rod 14 and the lower connecting rod 3 achieve the limiting and fixing effect. As the upper beam frame 1 rises, with the clamping plate 6 clamping the carbon block 9, the lower beam frame 2 is driven to rise through the upper connecting rod 14 and the lower connecting rod 3, driving the carbon block 9 to be hoisted. The fixture structure on each group of lower beam frames 2 will adapt to the length of the carbon block 9 below it to achieve a stable clamping effect;After lifting the carbon block 9 and transporting it to the placement position, the crane lowers the upper beam frame 1 to make the carbon block 9 land. Then, with the mechanical descent of the upper beam frame 1, the upper connecting rod 14 bends with the lower connecting rod 3, and the included angle becomes smaller. The lower connecting rod 3 drives the clamping arm 5 to move outward, so that the clamping plate 6 is separated from the carbon block 9 until the upper beam frame 1 lands on the upper positioning column 21. When the carbon block 9 lands and the upper beam frame 1 continues to fall, the winding motor 11 starts, drives the winding shaft 12 to rotate through the reducer, and winds up the steel rope 13 until the sliding column 15 touches the inner top of the guide cylinder 22 and the steel rope 13 is tightened, making the distance between the upper beam frame 1 and the lower beam frame 2 the shortest and resetting to the state when the carbon block 9 is not clamped; The use of I-beam for the upper beam frame 1 can save costs. The grouped frame 101 can be connected to the lower beam frame 2, and the connecting beam 102 assists the grouped frame 101 to keep the structure of the upper beam frame 1 stable.;
