A Derrick Defect Inspection Robot

Abstract

The invention discloses a derrick flaw patrol robot. The derrick flaw patrol robot comprises a front trolley, a connecting structure and a back trolley. The front trolley is connected with the back trolley through the connecting structure. The front trolley comprises a front trolley frame, an antenna, a signal transmitter, a signal receiver, a moving camera, a front clamping drive mechanism, an electromagnet and a three-axis acceleration sensor. The back trolley comprises a back trolley frame, stepping motors, stepping motor drivers, a control device, a back clamping drive mechanism, an electromagnet and a power source device. The connecting structure comprises lead screws and round springs. The control device is connected with the signal transmitter, the signal receiver, the moving camera, the three-axis acceleration sensor, the electromagnets and the stepping motor drivers. The signal transmitter is connected with the antenna. The power source device supplies power to the whole system. By the adoption of the derrick flaw patrol robot, manual patrol is not needed, the labor resource is saved, and potential physical safety hazards are avoided, and the monitoring precision is improved at the same time. In addition, the derrick flaw patrol robot can conduct monitoring and feed back data in real time, and a monitor can conveniently conduct checking.

Description

technical field [0001] The invention relates to a derrick inspection device, in particular to a derrick defect inspection robot. Background technique [0002] The derrick is an important part of lifting equipment such as metallurgical mining, coal mining, and oil drilling. In the actual work of the derrick, under the influence of various factors such as working lifting load and fluctuating wind load, the derrick produces three-dimensional swing deformation in the plane and elevation directions. When the deformation exceeds a certain limit, it will seriously affect the safety of production and become the most dangerous safety hazard in the working process. For this reason, the dynamic deformation of the derrick must be mastered in order to take corresponding safety precautions. From top to bottom, the base strata of the derrick bracing are filled soil, loess-like silty clay, clay and residual soil. The material composition of this layer is complex, without the necessary co...

Problems solved by technology

[0004] 1. These detection methods require a lot of human resources, and the cost is high, and the data error is relatively large, the most important thing is that there are potential safety hazards

[0005] 2. These detection methods are rough detection and cannot accurately reflect the current situation of the derrick. They cannot accurately detect the details of the derrick, and there are great hidden dangers
