Embodiment Construction

[0026] The principle and characteristics of the automatic adjustment mechanism for the distance between the fingers and beams of the second-floor platform of the drilling and workover rig will be further described below in conjunction with the accompanying drawings (see the attached Figure 1-8 ).

[0027] The automatic adjustment mechanism for the distance between the finger beams of the second floor platform of the drilling and workover rig is a finger beam unit of the second floor pipe rack of the workover rig, and the second floor pipe rack consists of two or more sets of finger beam units on the second floor rack (see attached Figure 7-8). It consists of fixed finger beam 1, sliding finger beam 2, flipping finger beam 3, worm screw 4, worm gear 5, gear A6, gear B7, gear C8, gear bearing seat 9, transmission shaft bearing seat 10, motor 11, rack 12, The sliding seat 13, the two-story platform longitudinal beam 14 and the drive shaft 15 are composed; the second-story pla...

Abstract

The invention relates to an automatic adjusting mechanism for the distance between every two finger boards of a two-layer platform of a drilling workover rig and belongs to the technical field of exploitation of petroleum and natural gas. The mechanism consists of the fixed finger boards, the sliding finger boards, the overturning finger boards, worms, worm wheels, gears, motors, racks, sliding seats, transmission shafts and the like. Each overturning finger board is overturned to a position which does not influence pipe arrangement through synchronous driving of the motors, and meanwhile, thesliding finger boards slide to the required positions in parallel, so that the distance between every two finger boards is adjusted in order to adapt to the change of the diameters of different pipecolumns; automatic adjustment can be achieved remotely through only one key, staff have no need to carry out high-altitude operation on the two-layer platform, and then the requirement for placing pipe columns different in diameter can be met by a finger board frame; time and labor are saved, and the operation is safe and reliable. The mechanism solves the problems that when the diameters of pipecolumns of finger boards on existing two-layer platforms are changed, finger board frames need to be integrally disassembled and replaced or the finger boards are pried manually one by one, correspondingly the operation is inconvenient, and the high-altitude operation is high in dangerousness. The mechanism is particularly suitable for being matched with a pipe arrangement manipulator of the automated two-layer platform.

Description

technical field [0001] The invention relates to an automatic adjustment mechanism for the distance between finger beams of a second-floor platform of a drilling and workover machine, belonging to the technical field of oil and gas exploitation. Background technique [0002] Drilling and workover rig refers to a large workover rig, which is mainly used for overhaul operations. Overhaul operations sometimes require deepening and sidetracking of oil production wells, that is, drilling operations. Offshore workover rigs must be able to perform drilling operations, and land rigs sometimes perform workover operations, including tripping and running tubing. The diameter of the tubing used for land oil production is usually 2-3 / 8in~3-1 / 2in, the diameter of the tubing used for offshore oil production is usually 2-3 / 8in~4-1 / 2in, and the diameter of the drill pipe used for drilling is usually 4in ~5-1 / 2in. For conventional workover rigs, in order to ensure the root capacity of the se...
