Description
Technical Field
The invention relates to the field of power construction equipment, in particular to a stripping tool for an insulating protection layer coated outside a high-voltage cable.
Background
The power cable is a basic device which is indispensable for transmitting electric energy, transmitting information, manufacturing various motors, instruments and meters and realizing electromagnetic energy conversion, and is a necessary basic product in future electrification and information-based society. With the rapid development of the communication industry, the power cable industry develops rapidly, and the product has a plurality of varieties and a very wide application range. The power construction often requires stripping the outer insulating protective layer of the high-voltage power, and the operation needs to be completed by using a special stripping tool. The current better instrument of peeling off of effect is through the cutter scribing the degree of depth slightly less than the mar of insulating protective layer thickness on insulating protective layer, then tears insulating protective layer, has protected the cable core, but the mar degree of depth can't be quantized, thereby often can lead to destroying the transmission performance reduction that the cable core made the cable by constructor's range estimation setting, perhaps the mar degree of depth is not enough, can't be with the condition that insulating protective layer torn.
Disclosure of Invention
The invention provides a stripping tool for an insulating protection layer wrapped outside a high-voltage cable, which solves the problem that the stripping tool in the prior art cannot quantitatively set the scratch depth.
The utility model provides a high tension cable outsourcing insulating protective layer strips instrument, the novel nipple rectifier comprises a cylindrical shel, be equipped with on the barrel along the radial first installation pole of barrel, first installation pole pass the barrel lateral wall and with barrel sliding connection, be equipped with spring mechanism between first installation pole and the barrel, one serving that first installation pole is located the barrel is equipped with the gyro wheel, be equipped with the pointer on the first installation pole, be equipped with on the barrel along the radial second installation pole of barrel, the second installation pole passes through the screw thread roll adjustment mechanism and is connected with the barrel, one serving that the second installation pole is located the barrel is equipped with the cutting knife, be equipped with length scale on the second installation pole, first installation pole sets up with the second installation pole relatively. The first mounting rod and the second mounting rod are arranged oppositely, namely the axis of the first mounting rod is parallel to the axis of the second mounting rod and is positioned on the same side of the cylinder.

Spacing roller rotates with the support to be connected, prevents that frictional force from hindering the removal of second installation pole.
Furthermore, three first installation rods and three second installation rods are arranged on the barrel body, the first installation rods are evenly distributed on the circumference, and the second installation rods are evenly distributed on the circumference. Three scratches are marked on the cable insulation protective layer by the three cutters, so that the insulation protective layer can be conveniently torn off subsequently.
Furthermore, a guide mechanism for guiding the cable is arranged in the cylinder body. The cutting effect on the cable insulation protective layer is influenced by whether the cable is coaxial with the cylinder body or not, the guide mechanism can ensure that the cable is coaxial with the cylinder body, and the good cutting effect of the cutting knife is ensured.
