Electrically-driven limiting type racking platform fingerboard

Abstract

The invention discloses an electrically-driven limiting type racking platform fingerboard. The electrically-driven limiting type racking platform fingerboard comprises a fingerboard body symmetricallymounted on a racking platform, the fingerboard body comprises a plurality of fingerboard single tubes which are uniformly arranged, one ends of the fingerboard single tubes are welded with sleeves, the sleeves sleeve cross beams, two ends of the cross beams are welded on the racking platform, the end sockets of the other ends of the fingerboard single tubes are provided with motor-driven rotationstop levers, and the rotation stop levers are connected to a motor driving mechanism. According to the electrically-driven limiting type racking platform fingerboard, by arranging the motor-driven rotation stop levers, automatic limiting of drill strings arranged in the fingerboard body is realized, and limiting time of the drill strings is reduced; meanwhile, space between the fingerboard singletubes can be adjusted flexibly, upturning the single fingerboard or multiple fingerboards simultaneously can be realized, operation risks are reduced, the working efficiency of tripping and the utilization rate of a racking platform stand area are improved, the working strength of workers are relieved, and the occurrence rate of racking platform operation dangerous accidents is lowered.

Description

technical field [0001] The invention belongs to the technical field of petroleum drilling equipment, and relates to an electric-driven position-limiting two-story platform finger beam. Background technique [0002] In order to prevent the drill string discharged in the finger beam of the second floor of the derrick from toppling, it is necessary to limit the drill string. At present, the finger beams of conventional two-story platforms are generally equipped with hanging chains or pallets to limit the drill string, which requires the manual operation of the derrick operator to limit the drill string. During the drilling process, the derrick worker has to disassemble the hanging chain or turn over the pallet every time the drill is tripped. This operation is labor-intensive, low in work efficiency and high in operation risk. [0003] According to the different drilling techniques of each well, the second floor of the derrick needs to discharge a variety of drill strings of d...

AI Technical Summary

Problems solved by technology

Since the spacing of the finger beams is not adjustable, when multiple specifications of drill strings are used at the same time, generally the finger beams can only be installed according to the largest drill string, which will reduce the discharge quantity of the drill string. When the required drill string exceeds the discharge quantity of the finger beam At the same time, it is necessary to dismantle the redundant drill strings and return them to the ground pipe rack, which is time-consuming, labor-intensive, low in work efficiency and high in operation risks
