Embodiment Construction
[0023] like figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7As shown, a hook-type personal security line includes a hook head 1, a grounding clamp 2, and a connecting wire 3 arranged between the hook head 1 and the grounding clamp 2 for conducting current or voltage at both ends. The hook head 1 is provided with a locking mechanism 4 that locks the wires in the hook head 1, and the hook head 1 is provided with an installation operation rope 5 that controls the wires to be locked in the locking mechanism 4. The hook head 1 is also provided with a dismounting operation rope 6 for controlling the wire to break away from the locking mechanism 4. The cross section of the hook head 1 is U-shaped, and the installation operation rope 5 is arranged at the tail of the hook head 1. The dismounting operation rope 6 is arranged on the head of the hook head 1, and the locking mechanism 4 includes a first lock piece 41 that is rotatably connected in the ho...

The invention relates to a hook type personal security line which comprises a hook head, a grounding end chuck and a wire. A locking mechanism is arranged in the hook head. An installation operation rope and a detachment operation rope are arranged on the hook head. The hook type personal security line has the advantages that the hook head is pulled through the installation operation rope so that an opening of the hook head can be aligned with the wire, the locking mechanism locks the wire, the hook head is turned through the weight of the wire so that the opening of the hook head can face downwards, the personal security line installation work is achieved, the defects that an existing chuck is small in interval and can hardly be aligned with the wire and thrown to be hung on the wire are overcome, and the defect that the existing chuck is low in clamping degree is overcome; the hook head is disengaged from the wire through the detachment operation rope, the detachment work can be achieved, the work intensity of operators is lowered, the safety performance is improved, the use effect is good, operation is easy, and the chuck is prevented from being disengaged when the operators conduct misoperation.
Description
technical field [0001] The invention relates to a hook type personal security line. Background technique [0002] For lines above 35kV level, due to the long line path and large spans, the tower design basically adopts the design of high tower height and phase spacing, and the wire erection basically adopts the hanging method (but now some 10kV lines are also used due to the constraints of geographical location and other conditions). The above method), due to the above problems, the design of the personal security line basically adopts the hanging design. The biggest advantage of the hanging personal security line is that it is easy to carry and light. It is difficult to align the wires for hanging, and after the chuck is used for a long time, the spring fatigue and elasticity will decrease, and the clamping degree of the chuck will also decrease, so that the ground wire that is finally hung up should be shaken by the wire or accidentally dropped by the operator.
