Automatic tube rod conveying machine

Abstract

The invention discloses an automatic tube rod conveying machine which comprises a rack, a lathe groove, an upper unloading frame, a feeding hook frame, a feeding oil cylinder, a winch, a material jacking oil cylinder and pulley mechanisms, wherein the lathe groove, the upper unloading frame, the feeding hook frame, the feeding oil cylinder, the winch, the material jacking oil cylinder and the pulley mechanisms are arranged on the rack. The feeding hook frame is driven by the feeding oil cylinder to swing up and down. One end of the rack is provided with a first sliding roller, and the other end of the rack is provided with a second sliding roller. One side of the rack is provided with a feeding pipe bridge, and the other side of the rack is provided with an unloading pipe bridge. The lathe groove is formed in the upper portion of the rack. The lathe groove is internally provided with a tube conveying trolley and a tube conveying trolley limiting device. The tube conveying trolley is internally provided with a clamping oil cylinder. Steel wire ropes are wound around the winch, tensioned by the pulley mechanisms and then connected with the tube conveying trolley. The automatic tube rod conveying machine is low in production cost, safe, reliable, convenient to maintain and easy to popularize and solves the problem that an existing conveying machine can only be applicable to a big workover with a platform but cannot be applicable to a small workover.

Description

technical field [0001] The invention relates to an automatic conveying machine for pipe rods. Background technique [0002] As we all know, in the workover site of oil drilling and workover, the automatic pipe and rod conveyor is gradually promoted 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, and is safer than the previous manual pulling of the pipe. [0003] see figure 1 , figure 1 A pipe rod conveyor in the prior art is disclosed. The working principle of the pipe rod conveyor in the prior art is as follows: the rocking rod 1 is pushed by the lifting cylinder 2, and when the rocking rod 1 swings at an angle, the upper part of the entire frame is caused to (The two-section frame 3) rises as a whole, and stops when it rises to a predetermined height; then it starts to move obliquely, that is, the V-shaped pipe groove 5 is ...

Problems solved by technology

[0003] see figure 1 , figure 1 A pipe rod conveyor in the prior art is disclosed. The working principle of the pipe rod conveyor in the prior art is as follows: the rocking rod 1 is pushed by the lifting cylinder 2, and when the rocking rod 1 swings at an angle, the upper part of the entire frame is caused to (The two-section frame 3) rises as a whole, and stops when it rises to a predetermined height; then it starts to move obliquely, that is, the V-shaped pipe groove 5 is pushed by the propulsion cylinder 4, and the V-shaped pipe groove 5 is smoothly sent to the wellhead, so that it is convenient For worker operation, please refer to Chinese Patent Announcement No. CN203783493U, Chinese Patent Announcement No. CN203603787U, Chinese Patent Announcement No. CN203499592U and Chinese Patent Announcement No. CN202832293U. The pipe rod conveyors involved in the above four patents are all like this structure, the defect of this kind of pipe and rod conveyor in the prior art is that it can only be applied to a major workover with a platform, but not to a small workover, because there is no workover platform in a small workover, and oil field workover workers are standing For ground operations, if the conveyor moves the pipe rods very high, the oilfield operators cannot pick up or lift the elevators at all, so minor repairs cannot be carried out.
