Abstract
A self lifting foldable derrick applied in the oil drilling work of the oil field comprises a right sheet, a connecting pin, a support rack, and a left sheet; wherein the right and left sheets are connected into a front opening K-shaped derrick through a connecting pin; when in transportation, the lower pin of the connecting pin is dismantled, and the right sheet of the derrick is wounded around the upper pin by clockwise rotating in 90 degrees, and then folded into a box shape, and the right sheet is connected with the support rack by bolt. The utility model solves the problems of large intensity in dismantlement, mounting, delivery and carryover and labor; and long carryover transportation period, excessive transportation times and low moving efficiency in prior art. The utility model can be widely applied in the oil drilling work of the oil field.
Description
Technical field:
The utility model relates to the bootstrap type jacknife mast that a kind of oil field oil-well rig is used.
Background technology:
China oil field has oil-well rig boring tower now, and its form of structure is according to clear derrick height, generally is divided into the 4-5 section, and each segment structure forms basic identical, is connected to become integral body by steelframe with pin by left sheet and right sheet.During transportation with about sheet and steelframe all dismantle, delivery or transportation separately, the problem that this derrick exists is that demolition, installation, shipping, labour intensity are big; The removal of home haul-cycle time is long, and the transportation train number is many, and movement efficient is low.
The utility model content:
The utility model purpose is to provide a kind of bootstrap type jacknife mast, and it is big that it has solved the existing derrick demolition, installation, shipping, the labour intensity that exist in the prior art; The removal of home haul-cycle time is long, and the transportation train number is many, the inefficient problem of movement.
The technical scheme that its technical problem that solves the utility model adopts is: the bootstrap type jacknife mast is made up of right sheet, connection pin, bracing frame, left sheet; With connect pin (upper and lower pin) by otic placode with about sheet connect into the K type derrick of an open front formula.The following pin that will connect pin during transportation is laid down, the right sheet of derrick is turn 90 degrees around last pin dextrorotation, be folded into square frame shape, with bolt right sheet is connected with bracing frame, form all delivery units in traffic coverage of a length, its construction profile is of a size of 10000mm * 2768mm * 2498mm.This structure has reduced cost of transportation widely, has improved dismounting and installation effectiveness, has alleviated labour intensity.
The new beneficial effect of this practicality is, this derrick has simple in structure, installs, demolition is convenient, is convenient to shipping, and labour intensity is little, be a kind of efficiently, flexibly, oil-well rig boring tower easily.
Description of drawings:
Fig. 1 is the utility model duty schematic cross-section.
Schematic cross-section when Fig. 2 is the utility model transportation.
Among the figure, 1, right sheet, 2, connect pin, 3, bracing frame, 4, left sheet.
The specific embodiment:
In Fig. 1, the bootstrap type jacknife mast is made up of right sheet 1, connection pin 2, bracing frame 3, left sheet 4; Right sheet 1 and left sheet 4 are by being connected the K type derrick that pin connects into an open front formula.
In Fig. 2, the following pin that will connect pin 2 during transportation is laid down, the right sheet 1 of derrick is turn 90 degrees around last pin dextrorotation, be folded into square frame shape, with bolt right sheet 1 is connected with bracing frame 3, form all delivery units in traffic coverage of a length, its construction profile is of a size of 10000mm * 2768mm * 2498mm and is convenient to transportation.
