Description

Technical Field

[0001] This utility model relates to the technical field of carbon block clamping devices, specifically an anode carbon block clamping device. Background Technology

[0002] The loading, unloading, and movement of anode carbon blocks all require an anode carbon block clamping device. The anode carbon block includes a clamping arm and a clamping plate fixed on the clamping arm. The clamping plate contacts the anode carbon block, and anti-slip pins are provided on the clamping plate to grip the anode carbon block. Patent application number 202121092786.6 discloses a special combined clamp for a carbon block stacking crane, in which the reinforcing plate is also provided with anti-slip pins, which are used to increase the friction between the plate and the anode carbon block.

[0003] Because the tips of the anti-slip nails are quite sharp, they can easily puncture the anode carbon blocks. Damaged carbon blocks will affect the production process and carbon block consumption during normal production. In addition, the anti-slip nails are directly connected to the clamping plate through threads. During use, the anti-slip nails will rotate under force, which will cause the anti-slip nails to change the distance they extend outward, or even cause the anti-slip nails to fall off. Utility Model Content

[0004] The main purpose of this utility model is to provide an anode carbon block clamping device to solve the problems in the prior art where the anti-slip nails on the clamping plate of the anode carbon block clamping device easily puncture the anode carbon block, and the anti-slip nails rotate when subjected to force, which causes the distance of the tip of the anti-slip nail to extend outward to change, or even causes the anti-slip nail to fall off.

[0005] To achieve the above objectives, this utility model provides an anode carbon block clamping device, including a first clamping arm and a second clamping arm for clamping the anode carbon block. The bottom inner sides of the first clamping arm and the second clamping arm are fixedly connected to clamping plates. The clamping plates are provided with multiple connecting holes, and bolts are connected in the connecting holes. The bolts include bolt heads and screws. The bolt heads are located inside the clamping plates and the end of the bolt head extends out of the connecting hole. The inner side of the bolt head is provided with anti-slip protrusions. The screw extends out to the outside of the clamping plates and is connected to a nut.

[0006] Furthermore, the connecting holes include a square hole near the inner side of the clamping plate and a round hole near the outer side of the clamping plate; the bolt head is square, the bolt head is inserted into the square hole, and the end of the bolt head extends out of the square hole.

[0007] Furthermore, multiple connection holes are evenly distributed on the clamping plate.

[0008] Furthermore, the lower parts of the first and second clamping arms are hinged to the two ends of the support rod; the top of the first clamping arm is hinged to the bottom of the first movable arm, and the top of the second clamping arm is hinged to the bottom of the second movable arm; the tops of the first and second movable arms are hinged to the hanger seats.

[0009] This invention increases the friction area and friction force with the anode carbon block by setting a bolt and adding an anti-slip protrusion on the bolt head instead of an anti-slip nail. This also avoids the anti-slip nail from puncturing the anode carbon block, thus preventing carbon block damage from affecting the production process and carbon block consumption.

[0010] This invention features a square hole and a square bolt head. The square hole limits the bolt head, preventing rotation and altering the distance the bolt head extends beyond the square hole, thus preventing the bolt from falling off. Attached Figure Description

[0017] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] like Figures 1 to 4 As shown, according to an embodiment of the present invention, an anode carbon block clamping device is provided, including a first clamping arm 1 and a second clamping arm 2 for clamping the anode carbon block. The bottom inner sides of the first clamping arm 1 and the second clamping arm 2 are fixedly connected to clamping plates 3. The clamping plates 3 are provided with a plurality of connecting holes 4, and bolts 5 are connected in the connecting holes 4. The bolts 5 include bolt heads 501 and screws 502. The bolt heads 501 are located inside the clamping plates 3 and the end protrudes out of the connecting holes (4). The inner side of the bolt heads 501 is provided with anti-slip protrusions, which are raised ridges. The screws 502 extend to the outside of the clamping plates 3 and are connected to nuts 6.

[0019] like Figure 4 As shown, the connecting hole 4 includes a square hole 401 near the inner side of the clamping plate 3 and a round hole 402 near the outer side of the clamping plate 3; the bolt head 501 is square and is inserted into the square hole 401; the end of the bolt head 501 extends out of the square hole 401; the bolt head 501 cannot rotate around the center line of the square hole 401; thus avoiding loosening between the bolt 5 and the nut 6 caused by the rotation of the bolt head 501.

[0020] like Figure 2 As shown, multiple connecting holes 4 are evenly distributed on the clamping plate 3, thereby making the bolts 5 evenly distributed and increasing the friction of the bolts 5 at multiple positions on the clamping plate 3.

[0021] like Figure 1 As shown, the lower parts of the first clamping arm 1 and the second clamping arm 2 are hinged to the two ends of the support rod 7; the top of the first clamping arm 1 is hinged to the bottom of the movable arm 8, and the top of the second clamping arm 2 is hinged to the bottom of the movable arm 9; the tops of the movable arm 8 and the movable arm 9 are hinged to the lifting seat 10.

[0022] The working principle of the above embodiments is as follows:

[0023] The first clamping arm 1 and the second clamping arm 2 are located on both sides of the anode carbon block to be clamped. The hook is connected to the lifting seat 10 and pulled upward. Under the action of gravity, the bottom ends of the first clamping arm 1 and the second clamping arm 2 approach each other, and the clamping plates 3 on the first clamping arm 1 and the second clamping arm 2 clamp the two sides of the anode carbon block. Then the hook moves the anode carbon block to the designated position and puts it down. The hook releases the lifting seat 10 downward, and the clamping plates 3 on the first clamping arm 1 and the second clamping arm 2 loosen the anode carbon block.

[0024] In existing technologies, anode carbon block clamping devices with anti-slip pins are used to clamp anode carbon blocks, which often results in the anode carbon blocks being punctured.

[0025] The anode carbon block clamping device of this embodiment increases the friction area and friction force by setting bolts and adding anti-slip protrusions on the bolt heads instead of anti-slip nails. This avoids the anti-slip nails puncturing the anode carbon block, thus preventing carbon block damage from affecting the production process and carbon block consumption. After using the anode carbon block clamping device of this embodiment, the problem of anode carbon blocks being punctured no longer occurs.

[0026] In existing anode carbon block clamping devices, the anti-slip pins are directly connected to the clamping plate via threads. During use, the anti-slip pins will rotate under force, which will cause the distance the anti-slip pins extend outward to change, or even cause the anti-slip pins to fall off.

[0027] The anode carbon block clamping device in this embodiment uses a square hole and a square bolt head. The square hole limits the bolt head, preventing the bolt from rotating and eliminating the problem of the bolt falling off due to changes in the distance the bolt head extends out of the square hole.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
