Device for pre-detecting aging degree of cable before laying

Abstract

The invention relates to a device for pre-detecting the aging degree of a cable before laying, and the device comprises a main control computer and a seat plate, a first connecting rod is fixed above the seat plate, and a first supporting plate is fixed at the tail end of the first connecting rod. And a cable detection device is arranged at the top of the first supporting plate. And the cable detection device comprises an arc-shaped plate and an ultrasonic probe. The lower portions of the two axial ends of the arc-shaped plate are each fixedly provided with an end plate, the end plates are fixedly connected with the first supporting plate, a supporting ring is fixedly connected to the lower portion of the arc-shaped plate, a plurality of second sleeves are fixed to the supporting ring in the radial direction, second sliding rods are inserted into the second sleeves, and the second sleeves and the second sliding rods are jointly sleeved with second springs. The bottom of an ultrasonic probe is fixedly connected with the tops of the second sliding rods, and the top of the ultrasonic probe penetrates the arc-shaped plate to be above the arc-shaped plate. According to the invention, the aging degree of each part of the cable can be detected in an ultrasonic mode, and the use safety of the laid cable is ensured.

Description

technical field [0001] The invention belongs to the technical field of cable detection, and in particular relates to a device for pre-checking the aging degree of cables before they are laid. Background technique [0002] The cable has a specified service life, but during the daily use of the cable, it may experience external force damage, damp insulation, chemical corrosion, long-term overload operation, cable joint failure, and the external environment and heat source of the cable may cause the cable temperature to be too high. High, insulation breakdown, etc., these phenomena will cause partial premature aging of the cable, resulting in potential safety hazards. Therefore, it is necessary to inspect the cables regularly to judge the aging degree of each part of the cables. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a device for pre-inspecting the aging degre...
