Cable crane video monitoring system for concrete construction

Abstract

The invention discloses a cable crane video monitoring system for concrete construction. The cable crane video monitoring system comprises a camera which is arranged below a cross-shaped part on the upper part of a cable crane lifting hook and is provided with a downward lens, wherein a wireless communication module and a power module are also fixed on the cable crane lifting hook; the power module supplies power to the camera and the wireless communication module; the wireless communication module is wirelessly connected with a remote server of a display device. According to the cable crane video monitoring system for the concrete construction, a cable crane can be effectively monitored in the operation process of the cable crane, actual peripheral images of the cable crane lifting hook and a lifted object are obtained in real time, an operator is effectively assisted in mastering field details, and an operation accident is avoided.

Description

technical field [0001] The invention relates to a quality monitoring system used for the pouring and construction of concrete engineering of water conservancy projects, in particular to a cable machine video monitoring system in concrete construction. Background technique [0002] Cable machine is a commonly used construction machinery in the transportation process of concrete pouring in water conservancy projects. It has large load capacity and high transportation efficiency. It is one of the key construction equipment that affects the construction strength, project duration and project quality of concrete pouring. The cable crane is a crane that uses the load-bearing cable tensioned between the main and auxiliary towers as the track of the load trolley. It is suitable for construction sites with complex terrain and difficult to pass through, such as earthworks in low-lying areas, dams, rivers, valleys and other areas. Material delivery. In water conservancy projects, the ...

AI Technical Summary

Problems solved by technology

In water conservancy projects, the main and auxiliary towers of the cable crane are often arranged on both sides of the river, with a large span (up to hundreds of meters). It is difficult to accurately control the space position of the lifting object, which brings inconvenience to the operation of the cable machine, affects the transportation efficiency, and is not conducive to the operation safety management such as anti-collision

[0003] At present, in the on-site construction management of water conservancy projects, cable machine manufacturers often use the cable state to estimate the working conditions and positions of the cable machine hooks, and then extensively realize digital monitoring. Without real-time real-time image monitoring, it is difficult to grasp the details of the site

This cable crane control technology estimates the spatial position of the cable crane hook based on the telescopic length of the cable, without considering the inertia of the hoisted object, the deformation of the cable itself, and the influence of the wind. Use your own operating experience, the password of the commander at the starting point and destination of lifting to determine the position of the cable machine

This non-intuitive and direct way of cable crane positioning is greatly affected by human factors, and its accuracy is often linked to the experience level of the cable crane operator. It is difficult to obtain the spatial position of the object lifted by the cable crane accurately in real time, resulting It is often difficult to find the target loading position and target unloading position

At the same time, the construction period of large-scale projects is long and the work intensity is high during the peak period. Operators are prone to fatigue. Accidents are often caused by failure to grasp the details of the site and the actual situation. Occasionally, lifting objects collide with the mountain and other objects on the construction site, or even collide The occurrence of safety accidents of construction personnel brings hidden dangers to construction efficiency and construction safety
