In the oil exploitation, the reliability, safety and stability of the exploitation process are ensured, and the system of the exploitation equipment needs to be detected. The petroleum drilling machine system is the most important component of petroleum drilling equipment, and because the petroleum drilling machine system works in a severe environment for a long time, the petroleum drilling steel frame is often influenced by factors such as abrasion, oxidation, corrosion and the like, so that the service life, the safety factor and the production efficiency of the petroleum derrick structure are greatly reduced. If the damaged and invalid place of the derrick steel frame cannot be found in advance and replaced and maintained, huge disaster hidden dangers can be buried for mining, so that the damage detection of the oil derrick is carried out, the problem is found in advance and solved, and the method is a very important task.

At present, people mainly depend on manpower to climb on a derrick and carry out detection and maintenance, but the method has the following defects: 1) the efficiency is low, and the manpower can not be carried with the maintenance detecting instrument with larger quality. 2) The manual detection needs experienced technical staff, but in the actual production process, the field of the experienced staff cannot be met every time, and the detection requirement is severe. 3) Human observation can only find damaged parts outside the derrick structure, which is difficult to detect for internal damage. 4) The danger of work is increased when the staff works at high altitude and carries tools, and the threat of life and property safety is easily caused.

In order to solve the problems, the invention provides a robot capable of carrying a detection and maintenance instrument on a petroleum derrick.
