Abstract
The invention discloses a double-door casing elevator which comprises a semi-circular arc elevator main body; the left end and the right end of the elevator main body are respectively connected with a left valve and a right valve by a hinge pin, and a locking mechanism for locking the left valve and the right valve is arranged at the combining part of the left valve and the right valve. The double-door casing elevator has a reasonable structure, adopts a double-door structure, has a large opening, and can clamp a pipe column with large diameter, wherein the pipe diameter can reach 42in; and multiple safety locking mechanisms are arranged on the left valve and the right valve, so that a latch can not be opened when being used, and the use is safer and more reliable.
Description
Technical field
The present invention relates to a kind of lifting means that in oil, Natural Gas Drilling Operation, uses during casing job.
Background technology
In oil and gas well drilling casing job process, required sometimes sleeve pipe caliber is very big, and that existing laterally opened opposite opened elevator holds caliber is less, can not adapt to the needs of big caliber operation.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructurely, hold reliably, easy to operate, can adapt to the double door casing elevator that the operation of major diameter tubing string is used.
Technical solution of the present invention is:
A kind of double door casing elevator is characterized in that: comprise the semicircular arc elevator body, the left and right two ends of elevator body are connected with left and right valve by bearing pin respectively, at left and right valve apposition position the locking mechanism that left and right valve is sealed are set.
Described locking mechanism is multiple sealed form.
The present invention is rational in infrastructure, adopts double swing doors, and opening is big, can hold the major diameter tubing string, and caliber reaches 42in, and multiple insurance locking mechanism is set on the valve of the left and right sides, guarantees that lock bolt can not open in use, uses more safe and reliable.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
A kind of double door casing elevator comprises semicircular arc elevator body 1, and the left and right two ends of elevator body are connected with left and right valve 4,5 by bearing pin 2,3 respectively, at left and right valve apposition position the multiple locking mechanism that left and right valve is sealed are set.Multiple locking mechanism is made up of lock bolt 6, latch pin 13, lock pin spring 7, set lever 8, set lever pin 9, lock bolt cam 10, magnetic safety plug assembly 11 and safety plug 12 etc., when left and right sides valve and main body fastening, lock bolt tightly snaps together with right valve by the safety plug that set lever hooks on the right valve, and set lever tightly is hooked in safety plug by lock pin spring and lock bolt action of cam, and magnetic safety plug assembly tightly snaps together lock bolt and set lever etc. with right valve again.
