Detailed implementation manners

[0021] To make the objectives, technical solutions and beneficial effects of the present utility model clearer, the following further describes in detail the implementation manners of the present utility model with reference to the accompanying drawings.

[0022] As Figures 1 to 5 shown, the present utility model provides a cylindrical electrode clamping device, which includes a support frame 4 and a movable pull rod 1 that are vertically distributed and coaxially arranged. The movable pull rod 1 is slidably connected to the support frame 4, and the bottom end of the movable pull rod 1 penetrates through the support frame 4 and is located inside the support frame 4. An automatically openable and closable locking mechanism 2 is also installed between the bottom end of the movable pull rod 1 and the support frame 4. Specifically, during use, the top end of the movable pull rod 1 is hung on the hook of the lifting mechanism on the lifting equipment; when the locking mechanism 2 is in the open state, the movable pull rod 1 can slide along the support frame 4; when the locking mechanism 2 is in the closed state, the position between the movable pull rod 1 and the support frame 4 can be relatively fixed.

[0023] There are at least three clamping arms 5 arranged outside the support frame 4 and distributed in a circular array along the circumference of the support frame 4. One end of each clamping arm 5 is hinged to the support frame 4, and a clamping block 7 is installed on the inner side of the other end of each clamping arm 5. Moreover, an inclined linkage arm 6 is hinged between the bottom end of each clamping arm 5 and the movable pull rod 1. Specifically, the specific way of installing the clamping block 7 on the clamping arm 5 is prior art. By setting the movable pull rod 1, the support frame 4, the locking mechanism 2, the clamping arms 5, the linkage arms 6 and the clamping blocks 7, a clamp device that can be opened and closed can be formed. And because the clamping arms 5 are distributed in a circular array, the cylindrical electrode 40 in a vertical state can be clamped from the top of the cylindrical electrode 40, so as to facilitate the clamping of the cylindrical electrode 40 in a vertical state.

[0024] Specifically, in the initial state, the locking mechanism 2 is in a closed state, and the clamping arms 5 are in an open state; then when clamping the cylindrical electrode 40 in a vertical state, first, driven by the lifting mechanism on the lifting equipment, the whole of the present invention can be lowered until the bottom end of the support frame 4 abuts against the top surface of the cylindrical electrode 40. At this time, the clamping blocks 7 on the clamping arms 5 are all located outside the cylindrical electrode 40. Then, the locking mechanism 2 is automatically adjusted to the open state, so that the movable pull rod 1 can slide along the support frame 4. In this way, driven by the lifting mechanism on the lifting equipment, the movable pull rod 1 can rise relative to the support frame 4. During the rising process of the movable pull rod 1, under the action of the linkage arm 6, the clamping arms 5 can be closed to drive the clamping blocks 7 to approach and tightly abut against the outer wall of the cylindrical electrode 40, completing the clamping operation; in this way, when in use, the cylindrical electrode 40 in a vertical state can be clamped from the top of the cylindrical electrode 40, so as to facilitate the clamping of the cylindrical electrode 40 in a vertical state; then, driven by the lifting mechanism on the lifting equipment, the cylindrical electrode 40 can be lifted a certain distance and then hoisted.

[0025] When releasing the cylindrical electrode 40, first, driven by the lifting mechanism on the lifting equipment, the cylindrical electrode 40 is lowered until it abuts against the ground; then the lifting mechanism on the lifting equipment continues to unwind the steel wire rope. At this time, under the action of the self-weight of the movable pull rod 1, the movable pull rod 1 can continue to descend along the support frame 4. During the descending process of the movable pull rod 1, under the action of the linkage arm 6, the clamping arms 5 can be opened to drive the clamping blocks 7 to release the cylindrical electrode 40. And when the clamping blocks 7 release the cylindrical electrode 40, the locking mechanism 2 can be automatically adjusted to the closed state. Then, driven by the lifting mechanism on the lifting equipment, the whole of the present invention can be lifted to disengage from the cylindrical electrode 40.

[0026] The specific setting method of the locking mechanism 2 is as follows: Such as Figure 1 、 Figure 2 and Figure 4As shown, the locking mechanism 2 includes a motor 21 and an inverted U-shaped plate 22. The inverted U-shaped plate 22 is fixedly connected to the support frame 4 and is located below the movable pull rod 1. A strip-shaped through hole 23 is vertically formed on the top surface of the inverted U-shaped plate 22. The motor 21 is vertically installed in the movable pull rod 1. After the output shaft of the motor 21 passes through the bottom end of the movable pull rod 1, a connecting rod 24 is coaxially installed. The bottom end of the connecting rod 24 is fixedly connected to a locking block 25 that is opposite to and adapted to the position of the strip-shaped through hole 23. Both sides of the locking block 25 are located outside the connecting rod 24. Specifically, the motor 21 is a stepping motor and comes with its own power supply and start-stop switch, and the angle of each rotation of the motor 21 can be set to 90 degrees. When in use, as Figure 1 As shown, when the locking block 25 is parallel to the strip-shaped through hole 23, when the movable pull rod 1 descends along the support frame 4, after the locking block 25 passes through the strip-shaped through hole 23 and penetrates the inverted U-shaped plate 22, it can be located inside the inverted U-shaped plate 22. Then, when the motor 21 is started, the locking block 25 can be driven to rotate 90 degrees to form a cross with the strip-shaped through hole 23. At this time, the locking mechanism 2 can be adjusted to the closed state as shown in Figure 2 As shown. When opening the locking mechanism 2, the locking block 25 can be driven to rotate in the reverse direction or continue to rotate 90 degrees by the motor 21 to make the locking block 25 parallel to the strip-shaped through hole 23. Then, when the movable pull rod 1 ascends along the support frame 4, the locking block 25 can be moved out of the inverted U-shaped plate 22 through the strip-shaped through hole 23. At this time, the locking mechanism 2 can be adjusted to the open state.

[0027] Furthermore, as Figure 1 and Figure 2 As shown, the sides of the clamp blocks 7 away from the clamp arms 5 are serrated. In this way, when in use, when the clamp blocks 7 are pressed against the outer wall of the cylindrical electrode 40, the friction between the clamp blocks 7 and the cylindrical electrode 40 can be increased, thereby improving the stability of the clamping device when clamping the cylindrical electrode 40.

[0028] Furthermore, as Figure 1 、 Figure 2 and Figure 5As shown, a clamping mechanism 3 is installed on the inner side of the clamping arm 5 located between the clamping block 7 and the linkage arm 6, and the clamping mechanism 3 includes a fixing seat 31, and the fixing seat 31 and the clamping arm 5 are connected by a first connecting bolt 32. Specifically, when the fixing seat 31 is connected to the clamping arm 5, the screw end of the first connecting bolt 32 passes through the fixing seat 31 and is threadedly connected to the clamping arm 5, and the head of the first connecting bolt 32 is located in the fixing seat 31 and is tightly pressed against the fixing seat 31, which makes it easy to disassemble and assemble the clamping mechanism 3 on the clamping arm 5; secondly, a plurality of tooth pins 33 are fixedly connected in the fixing seat 31, and the end of the tooth pin 33 away from the clamping arm 5 is a pointed end and is located outside the fixing seat 31. Specifically, when in use, when the clamping block 7 is pressed against the outer wall of the cylindrical electrode 40, the end of the tooth pin 33 away from the clamping arm 5 can simultaneously press against the outer wall of the cylindrical electrode 40, thereby further improving the stability of the clamping device when clamping the cylindrical electrode 40.

[0029] Further, such as Figure 1 and Figure 2 As shown, the support frame 4 is fixedly connected with a number of hinge seats 8, which are equal in number to the clamping arms 5 and opposite in position. The end of the clamping arm 5 close to the support frame 4 is detachably fixedly connected to the first hinge plate 9 by a second connecting bolt 11. Specifically, the first hinge plate 9 is a convex structure; and when the first hinge plate 9 is connected to the clamping arm 5, the screw end of the second connecting bolt 11 passes through the first hinge plate 9 and is threadedly connected to the clamping arm 5, and the head of the second connecting bolt 11 is pressed against the first hinge plate 9, which makes it easy to disassemble and assemble the first hinge plate 9 on the clamping arm 5; secondly, the first hinge plate 9 They are respectively located in the hinge seat 8 and are hinged to the hinge seat 8 through a detachable first pin shaft 10. Both ends of the first pin shaft 10 respectively pass through the hinge seat 8, and the hinge seats 8 at both ends of the first pin shaft 10 are detachably fixed with a first clamping plate 12 for limiting the axial movement of the first pin shaft 10 through bolts, that is, the first clamping plate 12 is detachable. Specifically, when in use, after removing the first clamping plate 12, the first pin shaft 10 can be pulled out. At this time, the clamping arm 5 and the support frame 4 are in a separated state, which can facilitate disassembly and assembly between the clamping arm 5 and the support frame 4.

[0030] Further, such as Figure 1 and Figure 2As shown, at the hinge positions of the clamping arms 5 and the linkage arms 6, second hinge plates 14 are detachably and fixedly connected through third connecting bolts 13. Specifically, the second hinge plates 14 are of a convex structure. When the second hinge plates 14 are connected to the clamping arms 5, the screw end of the third connecting bolt 13 passes through the second hinge plates 14 and is threadedly connected to the clamping arms 5, and the head of the third connecting bolt 13 abuts against the second hinge plates 14, which facilitates the disassembly and assembly of the second hinge plates 14 on the clamping arms 5. Secondly, the second hinge plates 14 are respectively located inside one end of the linkage arms 6 close to the clamping arms 5 and are hinged to the linkage arms 6 through detachable second pin shafts 15. The two ends of the second pin shafts 15 respectively penetrate through the linkage arms 6, and second clamping plates 16 for restricting the axial movement of the second pin shafts 15 are detachably and fixedly connected to the linkage arms 6 at both ends of the second pin shafts 15, that is, the second clamping plates 16 are detachable. Specifically, during use, when the second clamping plates 16 are removed, the second pin shafts 15 can be pulled out. At this time, the clamping arms 5 and the linkage arms 6 are in a separated state, which facilitates the disassembly and assembly between the clamping arms 5 and the linkage arms 6. In addition, since the clamping arms 5 and the support frame 4 can be easily disassembled and assembled, it is also convenient to disassemble and assemble the clamping arms 5 between the support frame 4 and the linkage arms 6.

[0031] Furthermore, as Figure 1 shown in Figure 2 figures, at the hinge positions of the movable pull rods 1 and the linkage arms 6, third hinge plates 17 are fixedly connected. The third hinge plates 17 are respectively located inside one end of the linkage arms 6 close to the movable pull rods 1 and are hinged to the linkage arms 6 through detachable third pin shafts 18. The two ends of the third pin shafts 18 respectively penetrate through the linkage arms 6, and third clamping plates 19 for restricting the axial movement of the third pin shafts 18 are detachably and fixedly connected to the linkage arms 6 at both ends of the third pin shafts 18, that is, the third clamping plates 19 are detachable. Specifically, during use, when the third clamping plates 19 are removed, the third pin shafts 18 can be pulled out. At this time, the linkage arms 6 and the movable pull rods 1 are in a separated state, which facilitates the disassembly and assembly between the linkage arms 6 and the movable pull rods 1. In addition, since the clamping arms 5 and the linkage arms 6 can be easily disassembled and assembled, it is also convenient to disassemble and assemble the linkage arms 6 between the movable pull rods 1 and the clamping arms 5.

[0032] To facilitate the hanging of the top end of the movable pull rod 1 with the hook of the hoisting mechanism on the hoisting equipment, therefore, as Figure 1 shown in Figure 2 figures, a lifting lug 20 is fixedly connected to the top end of the movable pull rod 1.
