Description

Technical Field

[0001] The utility model relates to the technical field of cable cutting, in particular to a hydraulic cable cutter for electric power construction operations. Background Art

[0002] Cable is a general term for optical cables, electrical cables and other items. Cables have many uses, mainly used for control installation, connecting equipment, transmitting electricity and other multiple functions. They are common and indispensable in daily life. Since cables are charged, installation requires special care. During the use of cables, they need to be cut with a cutter.

[0003] According to Chinese patent CN 216096174 U, a hydraulic cutter for cutting cables is proposed. In the device, a damping wheel arranged by rotation can drive a fixed housing, a connecting pipe and a fixed cutter to rotate around a connecting ring, and can drive a connecting rod and a mobile cutter to rotate around an output end of a hydraulic cylinder, so that the cutting position of the mobile cutter and the fixed cutter can be adjusted, and then the cable is placed between the mobile cutter and the fixed cutter, and an operation button is pressed to start a bidirectional gear pump to drive the hydraulic cylinder to drive the mobile cutter on the connecting rod to move along a slide groove toward the fixed cutter, so that the cable located between the mobile cutter and the fixed cutter can be cut.

[0004] However, there may be some shortcomings in this patent. Since the surface of existing cables is curved, when the mobile cutting knife in the device cuts the cable during movement, the cable may shake, causing the mobile cutting knife to slip, thereby changing the cutting position of the cable and changing the cutting line, thereby affecting the cutting effect of the cable. After the cable is cut, since there is no effective protection for the cutting knife, it is easy to injure the operator and reduce the practical effect of the cutting knife. For this reason, we propose a hydraulic cable cutter for power construction operations. Utility Model Content

During the downward movement of the moving block 313, the moving cutter 317 is moved downward. During the downward movement of the moving cutter 317, it closes with the fixed cutter 2 to achieve cutting. When the cable cutting is completed, the operator can press down the rotating rod 311 to close the movable cutter 317 and the fixed cutter 2, and then flip the limiting ring 323 to make the limiting ring 323 disengage from the limiting of the T-block 325. Under the reaction of the extrusion spring 324, the T-block 325 and the limiting column 326 will be ejected, so that the limiting column 326 will bounce into the side inner wall of the rotating rod 311, thereby limiting the rotating rod 311, so as to achieve the purpose of closing the movable cutter 317 and the fixed cutter 2, and prevent the cutter from causing damage to the operator.
