Embodiment 1

[0034] The positive triangle detection device is connected by a pulley, a frame tower, and a driving pulley system.

[0035] The pulley includes a pulley frame, a mobile frame and a pulley support frame. The moving frame moves in the axial direction where the detection device is located. The trolley frame is a cuboid parallel to the axial direction, and the side is provided with a chute; the main body of the mobile frame is a flat structure parallel to the axial direction, and its two sides are provided with bends perpendicular to the flat plate, forming a three-sided non-rotary structure. The closed rectangular shell is provided with a protrusion corresponding to the chute at the bend, and is clamped in the chute on the trolley frame. The length of the mobile frame is 1 / 3-1 / 2 of the length of the trolley frame. Two pairs of components with different heights are fixed on the mobile frame parallel to the axial direction and upright. The relatively high component supports the ...

Embodiment 2

[0041] The inverted triangle detection device is connected by a pulley, a frame tower, a driving pulley system and an inverted triangle moving car 18.

[0042] Wherein, the pulley, the frame tower and the active pulley system are the same as the components adopted in the above-mentioned equilateral triangle detection device.

[0043]In addition, the guide rail 6 is set to pass through the main pulley frame tower 11, and placed between the driving pulley 16 and the pulley; an inverted triangle moving car 18 is arranged on the guide rail. The inverted triangle sports vehicle includes a sports vehicle body and the inverted triangle support frame arranged on the vehicle body. The inverted triangle support frame is placed on the car body.

[0044] The body of the sports car includes wheels and a supporting plate; wheels are arranged under the supporting plate; the supporting plate is as wide as the guide rail; the length of the supporting plate is 1 / 6-1 / 8 of the length of the guid...

Embodiment 3

[0052] The positive triangle detection and inverted triangle detection devices operate simultaneously to detect two wires at the same time.

[0053] The wire passes through the inverted triangle moving car, and the moving car detects the wire when it moves on the track. At the same time, another wire test piece is connected with the steel wire rope, the center of the wire is aligned with the top of the main pulley, and reciprocating motion is performed on the main pulley.

[0054] The wire travel of this comprehensive detection device is limited, so a travel limit protection switch 5 is provided at both ends of the guide rail; a limit induction bumper 7 is provided on the wire rope connecting the driving and driven pulleys, which are respectively used to limit the inverted triangle test. Displacement of modules and wires.

[0055] This comprehensive detection device is provided with a tension sensor 15 on the steel wire rope connected with the main pulley to measure the wire ...

Abstract

The invention provides a guide wire detecting device. According to improvement to the guide wire detecting device, the detecting device comprises a fixed hydraulic oil cylinder, a tackle, a tension loading assembly and a control cabinet which are all arranged in the same axial direction in sequence, wherein the tension loading assembly comprises a driving pulley system arranged corresponding to the tackle, a framework tower located between the driving pulley system and the tackle and provided with a driving pulley on the top, and / or an inverted-triangle moving trolley located between the framework tower and the driving pulley system, and a guide rail for the moving trolley to move in the axial direction. According to the guide wire pulley passing detecting device, an equilateral-triangle pulley passing detecting device and an inverted-triangle pulley passing detecting device can independently complete pulley passing detection, and the two systems can also complete pulley passing detection at the same time as required.

Description

technical field [0001] The invention relates to a power system detection device, in particular to a wire passing pulley detection device. Background technique [0002] The electric power industry is the basic industry of the national economy and the people's livelihood. The continuous and rapid growth of electricity demand has further accelerated the speed of electric power development. Optimizing the allocation of energy resources, ensuring national energy security, and providing high-quality, safe and reliable power supply for national economic and social development are important missions of the power industry to serve the society and build a harmonious society. [0003] In the process of erecting transmission lines, the wires pass through multiple pulleys one after another. If the stranding process of the wires or the unwinding machinery and technology are not suitable, the wires will be damaged to varying degrees in the process, such as loose strands, lanterns, jumping...
