Problems solved by technology

At present, the bridge cable inspection robot developed in China has not been widely used in the industry due to its shortcomings such as heavy weight, low intelligence, and inconvenient use.
At present, the inspection and maintenance of cable stays in the industry mainly adopt the method of setting up brackets or hoisting machines to carry relevant inspectors for inspection. This inspection method is not only low in efficiency, high in cost, but also has great dangers.

Embodiment Construction

[0013] The present invention will be further described below in conjunction with accompanying drawing:

[0014] like figure 1 , shown in Fig. two 2, the bridge cable detection device of the present invention is clamped on the cable (1) surface by fuselage (2) by three driving dollies. The frame is composed of two semi-circular shells, which are connected to form a complete circle by the hinge (7) and the lock (8); the tightness of the spring (4) is adjusted by rotating the spring tension switch (5), so that The rubber wheel (6) of the driving trolley is closely attached to the surface of the cable (1), so that it is fixed on the surface of the cable and does not slide down.

[0015] The basic components of the driving trolley are: two rubber wheels (6), a driving motor (11), a stroke encoder (12) and an aluminum alloy connecting chassis. Two rubber wheels (6) are installed on the aluminum alloy chassis through transmission shafts and bearings, one of the rubber wheels (6) ha...

Abstract

The invention discloses a bridge cable creep detection device and belongs to the field of industrial robots. The bridge cable creep detection device adopts a wrap-around type mechanical structure and is composed of two openable / closable semi-circular structures. The bridge cable creep detection device is provided with three groups of driving wheels and surfaces of the driving wheels are concave surfaces. The driving wheels have guide functions, are provided with driving motors and are uniformly arranged in circular housings. The bridge cable creep detection device is provided with a high-definition camera and realizes wireless control and wireless transmission. The driving wheels can contact with a bridge cable well, can stably operate and move on the bridge cable, and can support detection equipment for bridge cable detection. The bridge cable creep detection device can realize detection of surface and internal injuries of a bridge cable, can realize positioning and tracing of the surface and internal injuries, and is convenient for daily detection and maintenance of a bridge cable.

Description

technical field [0001] The invention relates to a mechanical device capable of crawling on bridge cables and suspenders, especially a mechanical device capable of moving up and down on the surface of bridge cables and carrying related detection equipment to detect the surface conditions of bridge cables and suspenders and the conditions of internal steel wires device. Background technique [0002] With the rapid development of our society, there are more and more long-span bridges. Cable-stayed bridges and suspension bridges have become the widely used bridge types of modern long-span bridges. After the cable-stayed bridge is completed, the cable-stayed cables, one of the main stress-bearing components, are exposed to the air for a long time. Steel wire bundles are also corroded by moisture and other acidic substances in the air, and in severe cases, wires may even break, endangering the safety of the bridge. Therefore, it is necessary to regularly inspect and maintain bri...
