Light-small pipe rod conveying device and working method thereof

Abstract

The invention discloses a light-small pipe rod conveying device which comprises a frame, a lifting device, a sliding base, a sliding part and a pushing device. The sliding part linearly moves on the sliding base under the action of the pushing device, a feeding structure is arranged above the sliding part and connected with the sliding part through an overturning and sliding device, the overturning and sliding device comprises a supporting plate, an overturning drive device and a sliding drive device, the overturning drive device and the sliding drive device are arranged on the supporting plate, the feeding structure comprises an upper feeding groove and a lower feeding groove, the upper feeding groove is connected with the sliding drive device through a first swinging plate, and the lowerfeeding groove is connected with the overturning drive device through a second swinging plate. Sufficient total pushing strokes and stability in the conveying process of pipe rods are ensured when the total length and total weight of the device are decreased, and energy consumption and cost in use are reduced.

Description

technical field [0001] The invention relates to the technical field of special equipment for the petroleum industry, in particular to a light and small pipe rod conveying equipment. Background technique [0002] In the workover site of oil drilling and workover, the use of pipe and rod conveying equipment is gradually promoted, the purpose is to realize the transmission of pipe and rod (oil pipe, tools, drill pipe, etc.) from the wellhead to the pipe bridge. It has high working efficiency, well protects the threaded thread of the pipe rod, and is safer than the previous manual dragging method. [0003] The existing pipe rod conveying equipment generally adopts the following structure. The rocking rod is pushed by the lifting cylinder. When the rocking rod swings to an angle, the upper part of the entire frame is raised as a whole, and stops when it rises to a predetermined height; Pushing, that is, the V-shaped pipe groove is pushed by the propulsion cylinder, and the pipe ...

AI Technical Summary

Problems solved by technology

[0004] However, it is unreasonable to adopt such a structure for the conveyor at the small workover site, because such a model is long in length and relatively heavy in weight, and requires a long truck to be towed away. Generally, one well needs to be completed on the same day for small workover work. Quick loading and unloading equipment is needed, and such models are long and heavy, and the transportation cost is high; in addition, there are oil pipes and sucker rods in small workover wells, and the sucker rods themselves have poor roundness and poor rolling ability. The groove turning angle is small, and the sucker rod cannot be rolled out; in summary, the existing pipe and rod conveying equipment cannot meet the needs of small workover
