DETAILED DESCRIPTION
[0019] The utility model is further described below in conjunction with the accompanying drawings.
[0020] The orientations mentioned in this specification are based on the orientations of the electrolytic aluminum lifting bag installation and pipe clamp of the utility model during normal operation, and do not limit the orientations during storage and transportation. They only represent relative position relationships, not absolute position relationships.
[0021] Embodiment 1:
[0022] like Figure 1 As shown, a clamp for installing a tube for lifting and wrapping aluminum in an electrolytic process comprises a clamp 2 and a steel wire rope 4. The clamp 2 comprises a first clamp handle 21 and a second clamp handle 22 which are hinged to each other in the middle. A first clamp head 211 is fixed to the bottom of the first clamp handle 21. In this embodiment, for the convenience of processing, the first clamp head 211 and the first clamp handle 21 are an integrated structure. A first lifting ring 212 for the steel wire rope 4 to pass through is fixed to the top of the first clamp handle 21. A second clamp head 221 is fixed to the bottom of the second clamp handle 22. In this embodiment, for the convenience of processing, the second clamp head 221 and the second clamp handle 22 are an integrated structure. A second lifting ring 222 for the steel wire rope 4 to pass through is fixed to the top of the second clamp handle 22. The steel wire rope 4 passes through the first lifting ring 212 and the second lifting ring 222 in sequence and is hooked on the overhead crane.
[0023] A through hole is respectively opened in the middle position of the first clamp handle 21 and the second clamp handle 22, and a hinge shaft 23 is passed through the through hole. The first clamp handle 21 and the second clamp handle 22 are hingedly connected by the hinge shaft 23, so that the first clamp handle 21 and the second clamp handle 22 can rotate around the hinge shaft 23, so that the first clamp handle 21 and the second clamp handle 22 can drive the corresponding first clamp head 211 and the second clamp head 221 to cooperate with each other to clamp the workpiece, thereby ensuring the use effect of the device.
[0024] Furthermore, the first clamp head 211 and the second clamp head 221 are arc-shaped structures arranged opposite to each other; this structural design can increase the area of the opposite sides of the first clamp head 211 and the second clamp head 221 after they are unfolded, so that they can accommodate the protruding part of the workpiece, ensure the clamping effect of the device, prevent the tube from falling off when clamping, and improve the safety of the device. Furthermore, the concave surface of the first clamp head 211 and the concave surface of the second clamp head 221 are both provided with anti-slip grooves; this structural design can improve the anti-slip properties of the inner side of the first clamp head 211 and the second clamp head 221, and further improve the safety of the device. When in use, multiple clamps 2 can be used simultaneously to clamp the same tube 6 as needed to ensure stability.
[0025] Directions:
[0026] The tube 6 is placed at the arc structure of the first clamp head 211 and the second clamp head 221, and the wire rope 4 is lifted by the overhead crane. The wire rope 4 lifts the first clamp handle 21 and the second clamp handle 22. At this time, under the action of gravity, the first clamp handle 21 and the second clamp handle 22 rotate around the hinge shaft 23 in the through hole, thereby driving the first clamp head 211 and the second clamp head 221 to cooperate with each other to clamp the tube 6; after clamping, the wire rope 4 lifts the tube 6, and the tube 6 can be lifted. Under the action of gravity, the wire rope 4 is always in a tensioned state, thereby avoiding relaxation during the process of clamping the tube 6 by the first clamp head 211 and the second clamp head 221, greatly improving the stability of the device, and effectively preventing the tube 6 from falling.
[0027] By using the device, the potential safety hazard existing in the installation of the bag 6 in the prior art can be avoided, the safety of the operator is improved, and the work efficiency is improved.
[0028] Embodiment 2:
[0029] like Figure 1 As shown, in order to achieve stable clamping, the lateral distance of the clamp 2 is increased, thereby increasing the contact area between the clamp 2 and the package tube 6, so this embodiment is further improved on the basis of the first embodiment. The first clamp head 211 and the second clamp head 221 have the same structure and are arranged oppositely, so the following only takes the first clamp head 211 as an example for structural description.
[0030] The first clamp head 211 includes two clamps 2111 with a certain distance, and the two clamps 2111 are fixedly connected by a fixed shaft 2112. The fixed connection of the fixed shaft 2112 realizes the lateral width of the clamp 2, thereby improving the stability of the clamping.
[0031] Embodiment three:
[0032] In order to achieve smooth sliding of the steel wire rope 4, the present embodiment is further improved on the basis of the first embodiment, and the first hanging ring 212 and the second hanging ring 222 are set as movable pulleys, and the steel wire rope 4 is wound around the movable pulleys.
[0033] Embodiment 4:
[0034] In order to facilitate the disassembly of the package tube 6, this embodiment is further improved on the basis of the first embodiment.
[0035] A clamp for installing a tube for lifting and installing an electrolytic aluminum ladle also includes a hook 1; a clamp 2 is located at the bottom of the hook 1, and a steel wire rope 4 connects the hook 1 and the clamp 2.
[0036] like Figure 1 and Figure 2As shown in the figure, a hoisting hook 11 fixed to the overhead crane is fixed on the top of the hook 1, and a wire rope hook is fixed on the bottom. In order to achieve smooth sliding, the wire rope hook is a fixed pulley. Guide wheels 13 are arranged on both sides of the hook 1, and the wire rope 4 is wound on the guide wheels 13, thereby avoiding the corner wear of the wire rope 4 and the hook 1.
[0037] A downwardly extending limit plate 3 is installed at the bottom of the hook 1, and the top of the limit plate 3 is rotatably installed on the hook 1. A hook 31 hooked on the hinge shaft 23 is provided at the bottom of the limit plate 3. A rotating handle 32 is provided on the limit plate 3, and the rotating handle 32 drives the limit plate 3 to rotate.
[0038] When the clamped package tube 6 needs to be disassembled, the overhead crane drops the hook 1, and the wire rope 4 releases the first clamp handle 21 and the second clamp handle 22. At this time, under the action of gravity, the first clamp handle 21 and the second clamp handle 22 rotate to both sides around the hinge shaft 23, thereby driving the first clamp head 211 and the second clamp head 221 to cooperate with each other to release the package tube 6; continue to drop, hook the hook 31 on the hinge shaft 23, so that the position of the hook 1 and the hinge shaft 23 is fixed. When the hook 1 is lifted up again, the first clamp handle 21 and the second clamp handle 22 will no longer rotate around the hinge shaft 23, and the first clamp head 211 and the second clamp head 221 will not re-clamp the package tube 6 when they rise. When re-clamping is required, the rotating handle 32 is rotated to release the hook 31 from the hinge shaft 23, so as to achieve re-clamping.
[0039] The utility model discloses a tube clamp for installing an electrolytic aluminum lifting bag, which solves the technical problems in the prior art of unstable tube replacement and clamping, which is prone to safety accidents. The utility model provides a clamp to achieve stable clamping of the tube, greatly improves the stability of the lifting, and reduces the accident rate.
[0040] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
