Novel derrick climber

Abstract

The invention discloses a novel derrick climber, wherein the structure of the climber is composed of a control part, a transmission mechanism, an adsorption device, an adjusting device and a moving device. The working principle of the climber is that the gravity is absorbed on the derrick statically by the suction device, the power source transmits the power to the moving mechanism through the transmission mechanism, and finally the climbing and steering motion is realized. The control part coordinates the suction device and the moving mechanism, and the adjusting device is used to keep the crawling arm parallel to the crawling surface. The invention discards the mechanical clamping device which is complex and large in size, and simplifies the whole structure of the climber. The climber can climb on the main leg of the derrick by means of electric motor and program control, climb up the derrick to complete the detection work by the route set by a certain speed delay, and has certain flexibility to realize the steering from the main leg to the truss, and can be well adapted to the uneven crawling surface.

Description

technical field [0001] The invention relates to a machine for climbing a derrick and carrying a detection and maintenance instrument for maintenance, which belongs to the technical field of robots. Background technique [0002] In the actual development and production of oil and gas fields, in order to ensure the stability and safety of production, many production equipment and systems are required. Such as oil drilling operation equipment, oil well workover operation equipment, large-scale injection and production power supply equipment, among which the most important oil drilling equipment is the oil drilling rig system. In the long-term production activities of oil drilling rig derricks, the use environment is harsher than other types of derricks, and they are greatly affected by meteorological disasters, and some small derricks are often transported and unloaded in the field. Under such working conditions, the main steel frame structure of the oil derrick is easily affe...

Problems solved by technology

[0003] At present, the main flaw detection method of oil derricks and various towers is to manually carry detection equipment to climb up the tower for direct observation and equipment detection. This detection method still has many shortcomings: 1) The naked eye inspection method only Some large damages outside the main body of the derrick can be found, and it is difficult to find damage or small cracks that are difficult to reach inside the structure; 2) When manually or semi-manually carrying detection equipment and instruments to climb the derrick to detect the derrick, some detection equipment and instruments The load is large, or the operation on the derrick is complicated and inconvenient, which also greatly affects the reliability and stability of manual detection; Large, low work safety factor, low work efficiency and high labor cost and resource input cost
