An electric drive limit type two-story platform finger beam

Abstract

The invention discloses an electric drive limit type two-story platform finger beam, which includes a finger beam body symmetrically installed on the two-story platform. The finger beam body includes a plurality of evenly arranged finger beam single tubes, and one end of the finger beam single tube is welded There is a sleeve, the sleeve is set on the crossbeam, the two ends of the crossbeam are welded on the two-story platform, and the other end of the single tube of the finger beam is provided with a motor-driven rotary stopper, and the rotary stopper is connected with a motor drive mechanism. The invention realizes the automatic limit of the drill string discharged in the finger beam body through the motor to drive the rotating stop rod, and shortens the time for the limit of the drill string; at the same time, the distance between the single tubes of the finger beam can be flexibly adjusted, and single or multiple tubes can be realized. The simultaneous turning up of the finger beam reduces the operation risk, improves the working efficiency of tripping and the utilization rate of the vertical root area of ​​the second-story platform, reduces the labor intensity of workers, and reduces the incidence of dangerous accidents in the second-story platform operation.

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
