Biting-type antiskid stretching device for anti-termite cable

Abstract

The invention discloses a biting-type antiskid stretching device for an anti-termite cable. The device includes: gate posts, a fixing board, a support board, a driving motor, an adjustment rod, a clamping stretcher, a clamping cover, an inner wrapping column, a thread trough board, a sliding column, a sliding head, and an upper limiting column. When being inserted in a through hole, a cable is initially clamped and fixed under matched clamping effect of a 1# chuck and a 2# chuck, so that the cable, during the whole stretching process, is under a relatively straight status, which has convenience in biting in subsequent steps; the cable is limited by being wrapped with an arc-shaped frame and a semi-arc strip. Because the anti-termite cable is high in hardness, the surface of the cable can be tightly bitten by means of a design of surrounding nails, so that the cable is free of sliding during the stretching. The device can accurately measure the tensile strength of the anti-termite cable.

Description

technical field [0001] The invention relates to the field of cable stretching machines, in particular to fireproof cable stretching equipment. Background technique [0002] There are various types of cables, among which the anti-termite cable is a kind of cable with high strength requirements. After production, the fireproof cable needs to be stretched. The current technical application number is: CN201721032297.5, a kind of anti-termite anti-slip cable Cable stretching equipment, in which the anti-skid bump is round arch, the friction force is small when it is clamped with the cylindrical cable, and it is easy to get out of joint or slide slowly when stretching, which will make the cable stretch more Low, the current technical considerations are not comprehensive, and has the following disadvantages: [0003] The similar shape between the cable and the clamping part results in a small frictional force. When force is applied to both ends of the stretching, slow sliding or l...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a gripping and non-slip anti-termite cable stretching device to solve the problem of small friction due to the similar shape between the cable and the clamping parts, and the force exerted on both ends of the stretching Slow sliding or partial disjoint will occur when it is difficult for human eyes to distinguish, which will make the detected data of cable stretching inaccurate.
