The invention discloses an automatic tubular column placing device of a derrick racking platform. A pair of longitudinal guide rails is mounted on the front face of a derrick, and the longitudinal guide rails are connected into a whole; the pair of longitudinal guide rails is downwards connected with two transverse guide rails in a suspending mode, and the two transverse guide rails are connected into a whole; a first rack is arranged on the lower surface of each longitudinal guide rail, and a first hydraulic motor on one transverse guide rail is in engaged transmission connection with the corresponding first rack through a first gear; each transverse guide rail is downwards connected with a telescopic support in a suspending mode through a second roller mechanism, a second rack is arranged on the lower surface of each transverse guide rail, and a second hydraulic motor on the telescopic support is in engaged transmission connection with the second rack through a second gear; the telescopic support is slidably arranged in the derrick, and hinged to the end of a piston rod of a telescopic hydraulic cylinder, and the bottom end of a cylinder block of the telescopic hydraulic cylinder is hinged to a derrick fixing lug seat; and a winch is mounted at the inner end of the telescopic support. The automatic tubular column placing device of the derrick racking platform is compact in structure and reliable in operation.
Description
technical field [0001] The invention belongs to the technical field of petroleum machinery, and relates to an automatic pipe-discharging device for the second-floor platform of a derrick. Background technique [0002] Manually discharging pipe strings during drilling operations involves heavy workload, high repeatability, high labor intensity and high safety risks. However, although the automatic derrick of the pipe string processing system greatly reduces the labor intensity and safety risks of operators, and improves Operational efficiency, but the cost is high. Therefore, there is a need for an automatic mechanism with simple structure, low manufacturing and maintenance costs, and relatively high pipe discharge efficiency, which can effectively reduce the labor intensity and safety risks of operators, improve pipe string discharge efficiency, and do not require excessive economic costs. It meets the user's on-site requirements for the use of automatic piping on the secon...
