Embodiment Construction

[0026] The tension application system used in the wire detection device provided by the present invention is mainly composed of a main pulley assembly, a pulley frame, a rail pulley type tension application system, a control system and the like placed in the same axial direction. The pulley frame includes: a pulley frame I and a pulley frame II; the pulley frame I and the pulley frame II are respectively placed on both sides of the main pulley assembly; the guide rail is placed under the main pulley assembly and between the two pulley frames. The pulley frame is provided with side pulleys.

[0027] The main pulley assembly consists of a frame tower, a main pulley support structure, a main pulley and a camera. The frame tower is an iron frame structure, and the top is capped by a plate. The main pulley is installed on the top of the frame tower through sheet supports. The height of the main pulley assembly is 1.5-2 times the height of the side pulley. The two side pulleys an...

Abstract

The invention provides a tension exerting system for a conductor detection device. The detection device comprises pulley yokes, a main pulley component and a control cabinet which are sequentially arranged in the same axial direction; and the tension exerting system is characterized in that one pulley yoke is arranged outside each of two ends of a guide rail which is parallel to the axial direction; a drive part and a small pulley are respectively arranged on the inner side of each pulley yoke; the tension exerting system comprises a high-pressure oil cylinder, a tension sensor and a cart; both the high-pressure oil cylinder and the tension sensor are respectively arranged on the top of the cart; the high-pressure oil cylinder and the tension sensor are connected with a side pulley which is arranged on each pulley yoke. The conductor pulley-passing detection device adopts the track-cart tension exerting system, so that the stress on a conductor test specimen is more uniform, and the detection precision is improved.

Description

technical field [0001] The invention relates to a detection device for a power communication system, in particular to a tension applying system for a wire detection device. Background technique [0002] The electric power industry has developed rapidly, especially in recent years, with the continuous high-speed growth of electricity demand, the speed of electric power development has been further accelerated. As a basic industry related to the national economy and people's livelihood, the electric power industry optimizes the allocation of energy resources, ensures energy security, and provides high-quality and reliable power supply for national economic and social development. It is an important mission of the electric power industry to serve the construction of a socialist harmonious society. [0003] In the erection of transmission lines, the conductors must pass through multiple pulleys in turn to complete the erection. If the stranding process or pay-off machinery and ...
