Embodiment Construction
[0018] Attached below figure 1 to attach Figure 4 The present invention will be further described.
[0019] A special operating rod for live assembly and disassembly of a line alarm, comprising: an insulating rod 1, which is in a cylindrical structure; a cylinder body 2, which is installed on the head end of the insulation rod 1, and the front and rear ends of the cylinder body 2 are respectively provided with slots 3, The diameter of the inner hole of the cylinder 2 matches the outer diameter of the alarm, and the width of the slot 3 is larger than the fixing clip on the line alarm; two supports II 13 are respectively arranged on the inner walls of the left and right ends of the cylinder 2, The hinge plate 4 is rotated and installed on the support II 13 through the pin shaft I 5, one clamp arm of the clamp arm spring I 14 is connected with the hinge plate 4, and the other clamp arm is connected with the inner wall of the cylinder body 2; two stoppers 6. Set on the inner wa...

The invention discloses a line alarm charged assembly and disassembly special operating lever. An insulation rod drives a cylinder body to be inserted into a line alarm and pushes the line alarm upwards so that the line alarm slides downwards relative to the cylinder body, a fixing clamp of the line alarm can be placed in an opening groove, when the line alarm slides downwards, the line alarm pushes hinge plates to rotate downwards and compresses a first clamping arm spring, when the two hinge plates rotate downwards, the spacing of the two hinge plates becomes larger, after the line alarm fully enters the cylinder body, the first clamping arm spring drives the two hinge plates to be overturned upwards to be in a horizontal state, the two hinge plates close the line alarm, and then the insulation rod is pulled downwards; and as the upper ends of the two hinge plates are ejected by a blocking block, the hinge plates applies the downward pressure onto the line alarm, so that the line alarm is detached from a high-voltage line. After the line alarm is removed, the hinge plates rotate downwards through the manual operation, and then the line alarm can be removed from the cylinder body.
Description
technical field [0001] The invention relates to the field of electric power maintenance auxiliary tools, in particular to a special operation lever for live assembly and disassembly of a line alarm. Background technique [0002] With the development of the economy, production and life rely more and more on electricity, and the distribution of high-voltage transmission lines is also increasing and widening. In order to ensure the safety of high-voltage transmission lines and its surrounding personnel and equipment, more and more lines are hung with alarms to remind construction workers around high-voltage lines to pay attention to the safe distance between equipment and high-voltage lines to ensure safe production. [0003] The installation of the line alarm is different from other line warning devices. Because it is installed on the wire, when the alarm is damaged or needs to be disassembled beyond the service life, it will also face the problem of live disassembly. At pres...
