Problems solved by technology
This method of getting the drill pipe up and down the drill floor requires many operators, low efficiency, high labor intensity, poor safety, and serious damage to the drill pipe
[0004] In recent years, a small number of domestic petroleum machinery manufacturers have begun to develop automatic drill pipe conveying power catwalks, but most of them are low-grade products that imitate foreign technologies, such as wire rope traction power catwalks and simple lifting power catwalks, which are similar to foreign countries. Compared with the product, there are disadvantages such as low degree of automation, large vibration and noise of the catwalk during operation, unstable operation, and poor equipment reliability. The complete set rate of oil drilling equipment is low, which cannot meet the needs of the international high-end market, and it is difficult to win business opportunities in the international market competition

Embodiment Construction
[0031] The present invention as Figure 1-5 As shown, it includes a frame 2, the two sides of the frame 2 are symmetrically provided with overturning components, and a truss 1 is provided in the middle, one end of the truss 1 is hinged on the frame, and the other end is connected to the frame through a lifting hydraulic cylinder 14, so The cylinder body of the lifting hydraulic cylinder 14 is hinged on the frame, and the piston rod is hinged on the truss;
[0032] A stinger 12 is arranged on the truss, and a pipe groove 8 is arranged on the top of the stinger 12 .
[0033] When the truss is in a normal state, it is placed horizontally; when it is working, the hydraulic cylinder is lifted to make the truss inclined to form a ramp, which is convenient for the transportation of drilling tools (such as drill pipe 19).
[0034] The overturn assembly includes a lifting hydraulic cylinder 3, a telescopic hydraulic cylinder 4, a telescopic arm 5 and a casing 6, the casing 6 is hinged...

The apparatus is convenient to process and reliable to operate.
Description
technical field [0001] The invention relates to the field of petroleum drilling machinery, in particular to a conveying machinery for drilling tools (drill pipes, oil pipes, casings, etc.) up and down the drilling platform. Background technique [0002] The device for drilling tools to go up and down the drill floor in oil drilling field is called hydraulic ramp and drill pipe discharge system, or power catway for short. In the 1960s, foreign countries began to study power catwalks, and initially developed a programmable pipe processing system, which was first applied to offshore drilling platforms. The offshore drilling platform has a small working space, fewer operators, and the equipment does not need to be disassembled frequently, but the automation requirements are high. Therefore, the application of the programmable pipe handling system to the offshore drilling platform has achieved remarkable results. [0003] With the development of science and technology, in order...
