General rail shifting device for petroleum drilling machine

Abstract

The invention belongs to the technical field of petroleum drilling equipment, and in particular, relates to a general rail shifting device for a petroleum drilling machine. The device is characterizedby comprising a set of shifting units connected by connecting pins in sequence; each shifting unit comprises piece frames I and piece frames II arranged on the two sides, and combined cross beams andinclined beams for connecting the piece frames I and the piece frames II on two sides; the two ends of the combined cross beams are connected with the piece frames I and the piece frames II through connecting pins; and the combined cross beams and the inclined beams are connected through inclined beam lug bases. The device achieves compatibility and generality, is suitable for general rail shifting devices for large land electric petroleum drilling machines with multiple model numbers in different factories, solves the problems of multiple types of rail shifting devices matched with traditional drilling machines and only capability of adapting to one drilling machine by single rail shifting device, solves the problem of single use of different rail shifting devices, saves the trouble of arranging different rail shifting devices for different drilling machines for users, and saves a lot of resources for the users.

Description

technical field [0001] The invention belongs to the technical field of oil drilling equipment, and in particular relates to a general rail-type transfer device for oil drilling rigs. Background technique [0002] At present, secondary well exploration technology has been popularized in the field of oil and gas development. Due to the short spacing (generally 5-10m) and large number of secondary wells, the drilling rig derrick base equipment is frequently disassembled and assembled, which consumes a lot of manpower and material resources. In order to solve the above problems, As a rail-type transfer device that can avoid the disassembly and assembly of the drilling rig and can be used for the overall transfer of the drilling rig, it has been widely used in recent years. [0003] Due to the different dimensions of drilling rigs produced by different manufacturers, and the different dimensions of drilling rigs of different models produced by the same manufacturer, although the ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a general rail-type transfer device (suitable for electric drills ranging from 5000m to 9000m) suitable for different manufacturers and various types of large-scale land electric oil drilling rigs, which solves the problem of orbital transfer for existing drilling rigs. There are many types of devices, and a single orbital transfer device can only be used for one type of drilling rig, which solves the problem that different orbital transfer devices cannot be used universally, and saves users from having to equip different orbital transfer devices for different drilling rigs. The trouble of installation saves a lot of resources for users
