Problems solved by technology

However, the existing conveying devices generally adopt a four-link lifting structure. Due to structural limitations, the lifting weight can only lift a single oil pipe, and the lifting load is small.
Since the lifting trajectory of the four-link mechanism is determined, the lifting height of the four-link lifting conveying device cannot be adjusted, and the scope of application is small. It can only be used for special purposes, and the equipment has poor versatility.

Abstract

The invention discloses a special pipe string delivery device for stand workover equipment, and relates to the technical field of oil field workover equipment. The deformation of the arm folding mechanism and the rotation of the rear lifting mechanism are respectively realized through a folding arm hydraulic cylinder and a lifting hydraulic cylinder. In order to realize the adjustment of any position of the bearing platform and meet the use of diversified platforms, the main points of the technical scheme are: including the frame, the trolley clamping mechanism installed on the frame, the trolley mechanism, the rear lifting mechanism, the lifting fluid Cylinder, feeding mechanism, blanking baffle mechanism, discharging mechanism, pushing mechanism, bearing platform, feeding liquid cylinder, blanking baffle hydraulic cylinder, folding arm mechanism and folding arm hydraulic cylinder.

Description

technical field [0001] The invention relates to the technical field of oilfield workover equipment, and more specifically, relates to a special pipe string conveying device for stand workover equipment. Background technique [0002] During oilfield workover and drilling operations, it is necessary to continuously transport the pipe string from the ground to the drill floor, and use the hook of the traveling block to lower the pipe string or lift it out of the wellhead. During this process, the operator generally uses a small hydraulic winch to hoist one end of the pipe string, and drags the pipe string to the drill floor. In this way of operation, the pipe string is prone to problems such as colliding with the drill floor and falling off the hook. In order to solve the problem of pipe string transportation, at present, pipe transportation devices have been used in major oil fields. However, the existing conveying device generally adopts a four-link lifting structure. Due t...
