Drill rod automatic stacking and conveying device

Abstract

The invention discloses a drill rod automatic stacking and conveying device, which is mainly composed of a ramp part, a specific crane and a clamping arm and clamping jaw mechanism, wherein a slideway and a trolley are arranged below a suspension arm of the automotive crane; the trolley is provided with the clamping arm and clamping jaw mechanism which can be used for directly grabbing drill rods; a catwalk body provided with a groove is directly fixed on an inclined plane of the ramp; arranged pipe blocks (namely groove entering mechanisms) are arranged at two sides of the catwalk body; when the drill rods are conveyed to a drill floor, one drill rod is suspended to be placed on the arranged pipe blocks on the ramp by the crane, the drill rod rolls into the groove through the arranged pipe blocks, and is pushed to the drill floor through a pulley; when the drill rod is put down by the drill floor, the process is opposite to the above process; the drill rod which glides into the groove and is jacked and pushed onto the arranged tube blocks is automatically suspended onto the ground to be put in order by the crane; the catwalk body is in a fixed type and in a rotary type; the upper end of the rotary-type catwalk body is connected with the upper end of the ramp through a hinge; the lower side of the rotary-type catwalk body can be rotated upwards around a hinge under hydraulic control, and the rear end of the rotary-type catwalk body is lifted up. With the adoption of the drill rod automatic stacking and conveying device, a catwalk machine is leaved out, the arranging and conveying complete automation of the underground drill rods is realized, so that unmanned operation is realized.

Description

technical field [0001] The invention belongs to oil drilling equipment, in particular to an automatic stacking and conveying device for drilling rods. Background technique [0002] Existing petroleum and natural gas land drilling, drill pipe is transported on the well platform from the ground, mostly all is manual operation, and drill pipe is hung up with wire rope. Underground workers move the drill pipe weighing hundreds of kilograms to a position where it can be lifted. The work efficiency is too slow, and it is a kind of heavy physical labor. Work in rotation day and night. Now there is a catwalk machine, which can send the drill pipe to the well platform. And the drill pipe on the well platform can be transported down. However, there are not many drill pipes that can be discharged on both sides of the catwalk machine. To send the drill pipes to the discharge frame of the catwalk machine, or to move from the discharge frame to the designated position for stacking, it...

AI Technical Summary

Problems solved by technology

To send the drill pipe to the discharge frame of the catwalk machine, or move from the discharge frame to the designated position for stacking, it still needs manual operation, and the more important thing is: 1. The catwalk machine must always be installed and disassembled on the well site

2. All catwalk machines need to be transported

3. The cost of the catwalk machine is relatively high
