Description

Large-bearing-force structural frame Technical Field The invention relates to the technical field of oil and gas drilling, in particular to a frame with a large bearing stress structure. Background At present, the petroleum drilling machine with the land drilling depth below 4000 meters mainly adopts a vehicle-mounted mode, and has the advantages of flexible transportation and quick moving. The weight of the main machine belt of the drilling machine exceeding 4000 meters can reach or exceed 100 tons when the main machine belt of the drilling machine is transported, and skid-mounted drilling machines are often adopted at the moment due to the limitations of road transportation conditions, insufficient bearing of a conventional chassis and the like. The desert drilling machine is a special drilling machine developed aiming at special environments in desert areas, and compared with a conventional drilling machine with the same tonnage, the load carrying and escaping capabilities are improved. However, the frame of the desert truck-mounted drilling machine with a conventional structure can only be matched with a small desert tire due to the limitation of the carrying capacity and the height of a girder, the problems of small ground clearance of a chassis, insufficient trafficability and escaping capability exist, and various mechanical or hydraulic support legs cannot be reasonably arranged due to the limitation of a truck body structure, so that no effective path for transmitting the load on a carrying truck table surface to the ground exists in the frame, more stress concentration points can be formed in the frame, and meanwhile, the self-supporting stability of the carrying truck is poor due to the limitation of the width of the frame during operation. With the requirements of economic efficiency, effectiveness and operation stability of moving and transporting drilling rigs, the demands of customers on car-mounted oil drilling rigs which are operated in desert areas and are over 4000 meters are more and more urgent. The frame is used as a main carrier for transporting and working of the truck-mounted drilling machine, so that the frame with a large bearing structure suitable for desert environments needs to be designed, and the special tire for large desert is matched, thereby meeting the use requirements of oilfield users at home and abroad.
