External power pipe rod conveyor

Abstract

The invention provides an external power pipe rod conveyor, and relates to the technical field of oil field workover devices. The external power pipe rod conveyor comprises a rack, a hoisting mechanism, a telescopic mechanism, a turnover mechanism and a hydraulic system, wherein at least one side of the rack is provided with a feeding mechanism; the hoisting mechanism is arranged on the rack; thetelescopic mechanism is arranged on the hoisting mechanism; the turnover mechanism is arranged on the telescopic mechanism, the telescopic mechanism is used for driving the turnover mechanism to move,and the turnover mechanism is used for turning over towards one side of the rack; and the hydraulic system comprises a hydraulic quick coupling used for communicating with a hydraulic loop of an external hydraulic source, a flow control system used for controlling the flow of hydraulic oil in the hydraulic system, a high-pressure filter used for filtering the hydraulic oil in the hydraulic systemand a hydraulic valve set used for controlling all the mechanisms to act. Due to the arrangement, the external power pipe rod conveyor can be used in a well site with an electric hydraulic pump station, can also be used in a well site with a vehicle-mounted hydraulic power source when the electric hydraulic pump station cannot be powered on, and can meet the use requirements of any well site.

Description

technical field [0001] The invention relates to the technical field of oil field workover devices, and more specifically relates to an external power pipe and rod conveyor. Background technique [0002] With the development of technology, the operating equipment and technology of oil wells in oilfields are also constantly improving. In the traditional oilfield minor repair operations, most of the lifting and lowering pipe rods are manually pulled out. This traditional operation method is labor-intensive and low-efficiency. , many security risks. At present, the external power pipe and rod conveyors used in major oilfields for minor repair work use high-power motors as the power source to work, but for some water wells or places where electricity is far away and other places where electricity is inconvenient, external power pipe and rod conveyors cannot be used. Set the power tube rod conveyor. Therefore, how to solve the problem in the prior art that the external power pip...
