Description
Technical field
The utility model relates to a kind of hot line maintenance potential transfer deadlock lever.
Background technology
Live line working has become important means and the method for Electric Power Line Overhaul, defect elimination, accident treatment, and entering equipotential is the important process step of hot line maintenance, is directly connected to operating personnel's safety and operating efficiency.In existing electric transmission line equipotential live line working, adopt operating personnel to wear a complete set of screening clothing and approach wire by delivery vehicle, the tactile electrified body that directly catches when apart from electrified body certain distance is realized potential transfer and is entered equipotential, can produce electric arc operating personnel's safety is worked the mischief and damages screening clothing in potential transfer process.
Summary of the invention
The purpose of this utility model is that a kind of potential transfer deadlock lever of keeping away the direct contact electrification body of manual-free is provided.
To achieve these goals, the utility model mainly comprises metal hook, drainage thread, joystick, insulating bar, described metal hook, drainage thread is bolted to one end of insulating bar by aerofoil profile, the other end of described insulating bar is provided with joystick by rotating shaft, make handle form the lever construction that can rotate around the axis, described metal hook and inner side, insulating bar junction are provided with block ring by torque spring, the other end of described block ring is close on the bill inner side of metal hook, described insulating bar inside is provided with rope, one end of described rope is connected through the perforation of insulating bar and the upper end of joystick, the other end is connected with the block ring at bill place through the perforation of metal hook, described drainage thread is coil spring formula.
By above setting, the beneficial effects of the utility model are: avoided with the direct contact electrification body of hand, and easy accessibility, block ring makes to install more solid and reliable, avoid potential transfer bar in work to come off, telescopic drainage thread effectively prevents rocking of drainage thread, has greatly improved the fail safe of operation.
Brief description of the drawings
Now by reference to the accompanying drawings the utility model is described further.
Fig. 1 is structural representation of the present utility model.
In figure: 1, metal hook, 2, drainage thread, 3, block ring, 4, torque spring, 5, joystick, 6, rope, 7, insulating bar.
Embodiment
As shown in Figure 1, the utility model mainly comprises metal hook 1, drainage thread 2, joystick 5, insulating bar 7, drainage thread 2 is coil spring formula, metal hook 1, drainage thread 2 is bolted to one end of insulating bar 7 by aerofoil profile, the other end of insulating bar 7 is provided with joystick 5 by rotating shaft, make handle 5 form the lever construction that can rotate around the axis, metal hook 1 is provided with block ring 3 with insulating bar 7 inner sides, junction by torque spring 4, the other end of block ring 3 is close on the bill inner side of metal hook 1, insulating bar 7 inside are provided with rope 6, one end of rope 6 is connected with the upper end of joystick 5 through the perforation of insulating bar 7, the other end is connected through the perforation of metal hook 1 and the block ring 3 at bill place.
By above setting, when use, metal hook 1 is caught on to electrified body, current potential reaches screening clothing from metal hook 1 through aerofoil profile bolt and drainage thread 2, completes potential transfer.
