Abstract
A drilling rig derrick belongs to the field of oilfield drilling and comprises a first section, a second section, a third section, a fourth section, a five section and a crown block, wherein each section comprises a left rack and a right rack, a cross beam and an diagonal draw bar; the left rack and the right rack are in pin connection through the cross beam and the diagonal draw bar, and the sections are connected through pin shafts; and the five section adopts an integral welding structure, the cross section of the five section adopts a rectangular structure, and the five section is connected with the crown block through bolts and locating pins. When the derrick is disassembled and assembled, the five section and the crown block are moved integrally, so that the disassembly and assembly working capacity of workers is lowered, and the removal efficiency is improved.
Description
Technical field
The utility model relates to derrick used in the oil drilling field, especially a kind of drilling derrick.
Background technology
Along with Oilfield developing,, more and more higher to the each side requirement of rig in order to improve the quality of drilling well.Present used rig, derrick generally adopts " K " type frame, and it is five sections that this kind derrick is divided into, and each section is divided into parts such as left and right sides horse, crossbeam and diagonal member again.It is big that this kind drilling derrick exists the disassemble and assemble work amount, the problem of derrick general stability difference during work, thus influence drilling quality, reduced operating efficiency, increased drilling cost, be unfavorable for applying.
Summary of the invention
The utility model provides a kind of drilling derrick in order to solve weak point of the prior art, this drilling derrick easy accessibility, and have enough working depths, general stability is good during work.
A kind of drilling derrick comprises I section, II section, III section, IV section, V section and overhead traveling crane, forms by left and right sides horse, crossbeam and diagonal member for every section, and left and right sides horse carries out bearing pin by crossbeam, diagonal member and connects, and the employing bearing pin is connected between section and the section.The V section is an integral solder formula structure, and its cross section is a rectangular configuration, and the V section is connected with alignment pin by bolt with overhead traveling crane.
Described V section adopts two alignment pins to be connected with overhead traveling crane at least.
The beneficial effects of the utility model are: because this derrick V section adopts the monolithic absolute construction, the cross section is a rectangular configuration, and the derrick after the connection has the advantage that supporting capacity is big, general stability is good.During dismounting, V section and the movement of overhead traveling crane integral type have reduced workman's disassemble and assemble work amount, have improved resettlement efficient.
Description of drawings
Fig. 1 is the utility model structural representation.
1. I sections among the figure, 2. II section, 3. III section, 4. IV section, 5. V section, 6. overhead traveling crane, 7. left and right sides horse, 8. crossbeam, 9. diagonal member, 10. bearing pin
The specific embodiment
A kind of drilling derrick, comprise I section 1, II section 2, III section 3, IV section 4, V section 5 and overhead traveling crane 6, every section by left and right sides horse 7, crossbeam 8 and diagonal member 9 compositions, left and right sides horse 7 carries out bearing pin 10 by crossbeam 8, diagonal member 9 and connects, and I section 1 upper end adopts bearing pin 10 to be connected with IV section 4 lower ends, IV section 4 upper ends with V section 5 lower ends with III section 3 lower ends, III section 3 upper ends with II section 2 lower ends, II section 2 upper ends.V section 5 is an integral solder formula structure, and its cross section is a rectangular configuration, and V section 5 is connected with alignment pin by bolt with overhead traveling crane 6.V section 5 adopts two alignment pins to be connected with overhead traveling crane 6 at least, and during the derrick dismounting, V section 5 and overhead traveling crane 6 integral type movements have reduced workman's disassemble and assemble work amount, have improved resettlement efficient.
Claims (2)
1. a drilling derrick comprises I section, II section, III section, IV section, V section and overhead traveling crane, forms by left and right sides horse, crossbeam and diagonal member for every section, and left and right sides horse carries out bearing pin by crossbeam, diagonal member and connects; The section with the section between the employing bearing pin be connected, it is characterized in that: the V section is an integral solder formula structure, its cross section is a rectangular configuration, the V section is connected with alignment pin by bolt with overhead traveling crane.
