Hydraulic rotating lifting turning mechanism

Abstract

The invention discloses a hydraulic rotating and lifting turn-around mechanism, which belongs to turn-around machinery field. The mechanism comprises a rotary shaft, a fixed pedestal arranged around the rotary shaft, two rotating wings which are arranged in the same plane and can rotate around the fixed pedestal and a lifting frame arranged on the upper part of the rotating wings; a lifting oil cylinder is arranged on the lower part of the lifting frame to drive the frame to move vertically. The mechanism also comprises a rotary oil cylinder to drive the rotating frame and the rotating wings to rotate. By utilizing self-rotation of 180 degrees, the hydraulic rotating and lifting turn-around mechanism realize the in situ turning around of pipes, thus saving the space, facilitating reasonable layout of a production line as well as simplifying processes and increasing working efficiency; in addition, the hydraulic rotating and lifting turn-around mechanism has simple structure and convenient manufacture and can save production cost compared with the original turning-around vehicle.

Description

technical field [0001] The invention relates to the field of automatic processing machinery for pipe materials, in particular to a hydraulic rotary lifting U-turn mechanism. Background technique [0002] In the production and transportation of oil and natural gas, a large number of pipes, such as various oil pipelines or oil production casings, need to be applied. The manufactured pipe blank still needs to be further processed, such as installing parts on the pipe or turning threads. Due to the long length of the pipe, in order to facilitate processing, one end of the pipe is generally processed first; after one end is processed, the pipe is turned around, and then the other end is processed. At present, the processing of pipes in the oil and natural gas industry generally adopts an automated streamlined production operation. First, one end of the pipe is processed. After the processing is completed, the pipe is loaded into the U-turn vehicle, and the U-turn operation of th...

Problems solved by technology

[0003] However, there are many inconveniences in using vehicles to perform U-turn operations. First, the use of vehicles to perform U-turns requires a large space, and it is necessary to set up a U-turn running line for vehicles at the operation site. The U-turn movement can only be completed after the vehicle detours 180 degrees along the circular line. This will waste a lot of production space; secondly, the efficiency of using vehicles to turn around is low, and the vehicles need to take off the pipes from the production line and load them into the vehicles for turning around; Putting it on the assembly line increases the production and processing procedures; in addition, the cost of using vehicles to make a U-turn is also relatively high

[0004] If you use a mobile crane to complete the U-turn operation of the pipe, you must ensure that there are mobile crane facilities on the assembly line, which requires a large investment and is not suitable for factory buildings or outdoor implementation that do not have the installation conditions for mobile cranes.
