Novel portable metal sheath stripper for fireproof cable

Abstract

The invention discloses a novel portable metal sheath stripper for a fireproof cable. The novel portable metal sheath stripper structurally comprises the fireproof cable, a metal sheath stripping device and an anti-skid sleeve, wherein the fireproof cable runs through the metal sheath stripping device; and the anti-skid sleeve sleeves the outside of the metal sheath stripping device. Compared withthe prior art, the novel portable metal sheath stripper has the beneficial effects that a device does not need to be manually pulled to move back and forth on the cable and directly sleeves the cable, so that the device is always parallel to the cable, the metal sheath can be cut open once, the stripping time is short, cutting interruption of the metal sheath can be avoided and the stripping efficiency is improved; cutting knives can be adjusted once on the basis of spring characteristics and the adjusting speed is high, so that improvement of the stripping speed is facilitated; and four rotary cutting knives can cut the metal sheath at the same time and the cutting depths are the same, so that concave parts and convex parts of the corrugated metal sheath all can be cut, meanwhile, a cable core is not cut, the effect on the cutting effect due to different cutting depths is avoided, cutting is complete and secondary cutting and stripping are not needed.

Description

technical field [0001] The invention relates to the technical field of cables and wires, in particular to a novel portable metal sheath stripper for fireproof cables. Background technique [0002] In order to make the cable adapt to the requirements of various operating environments, a protective layer is applied outside the cable insulation layer. The cable protective layer can be mainly divided into metal protective layer, rubber-plastic protective layer and combined protective layer. In terms of metal protective layer , which is usually composed of a metal sheath and an outer sheath, mainly plays the role of mechanical protection and shielding, and also has the characteristics of fire resistance, corrosion resistance, compression and tensile resistance, water resistance, etc., and can prevent moisture and other harmful substances When entering the interior of the cable insulation, when laying the cable, making the terminal head, testing and measuring other aspects of perf...

AI Technical Summary

Problems solved by technology

[0005] 1) Pull the device to move back and forth on the cable during operation. It needs to be repeated 3-5 times to cut the metal sheath, which takes a long time to peel off. However, the metal sheath is made of metal, and it is laborious to pull it back and forth manually. The device is parallel to the cable, and the metal sheath is prone to stripping interruption, which affects the stripping efficiency;

[0006] 2) The two cutting wheels need to be adjusted through the adjustment rods connected to
