Drilling automatic device

Abstract

The automatic device for drilling is mainly composed of clamping seat mechanism, valve control mechanism, shift fork mechanism, latch control mechanism, jaw rotating arm mechanism, rotating arm mechanism and control system. It is mainly to turn all manual operations such as the valve of the elevator used on the well platform, the opening and closing of the locking mechanism, the insertion and removal of the latch, the removal and installation of the lifting ring, and the pulling of the elevator to the wellhead into a fully automatic operation. operate. Firstly, the hook of the clamping seat hooks the buckle on the back of the lifting ring, pulls it tightly and presses it against the positioning surface, and the lifting ring is fixed. The valve control mechanism on the clip seat stretches over to open or close the locking mechanism at once, and opens or closes the valve with a long dial. The clip in the fork mechanism above the clip seat mechanism can be rotated, telescopically caught and positioned on the suspension ring. The opening or closing of the fork mechanism will complete the removal and hanging of the suspension ring on the elevator, and the latch control mechanism will quickly pull out or insert the latch in the corresponding hole of the elevator. It can replace the workers' operations on the second-floor platform and the wellhead, which not only greatly reduces the labor intensity of workers, but also improves work efficiency.

Description

Technical field [0001] The invention relates to oil and natural gas drilling equipment, in particular to an automatic device for drilling. Background technique [0002] In the existing oil and gas drilling, the operation on the well platform is mainly manual, such as pulling the elevator back and forth at the wellhead and near the wellhead, inserting and pulling out the bolt in the lifting lug hole of the elevator, and pulling the lifting ring on the lifting lug of the elevator. Take out or hang up, open and close the elevator valve and lock door, all workers operate day and night, especially the workers on the second floor platform, the hardest work, not only to take out or insert the drill pipe from the elevator, but also to Pushing, pulling and pushing the drill rods into and out of the drill rod box takes a lot of physical effort. In addition, the drilling pipes are hoisted back and forth from the wellhead to the second-floor platform, and two workers are holding the dr...
