Problems solved by technology

[0002] At present, the preparation work before the workover of the oil well is basically carried out by manpower. The turning of the donkey head is an important link before the workover operation. The rope device ② realizes the turning of the donkey head so that the workover rig can work at the wellhead. The donkey head is connected to the end of the beam through two pins located on both sides of the beam, and the turning of the donkey head refers to removing the pin shaft on one side , the rotation of the donkey head around the axis of the pin shaft on the other side. At present, the above two tasks are carried out manually. The inventors found that this process usually requires a lot of manpower, which is inefficient, labor-intensive, and accompanied by high risks.

Abstract

The invention relates to a donkey head turning mechanism of a beam pumping unit, which comprises a bottom bracket, which is slidingly connected with a lifting bracket located above the bottom bracket, connected with a lifting mechanism, and the lifting mechanism can drive the lifting bracket to perform lifting movement. The lifting bracket is detachably connected with a first fixed shaft and a second fixed shaft that are distributed up and down. The traveling beam can pass through the space between the first fixed shaft and the second fixed shaft. The pendulum mechanism includes a tilting bracket slidingly connected with the lifting bracket. The tilting bracket can move along the axis of the first fixed shaft or the second fixed shaft. The tilting bracket is connected with a positioning piece and a tilting drive mechanism. The arm is connected, and the swing arm can be connected with the head of the donkey. The use of the swing mechanism of the present invention has low labor intensity and high work efficiency.

Description

technical field [0001] The invention relates to the technical field of workover equipment, in particular to a donkey head turning mechanism of a beam pumping unit. Background technique [0002] At present, the preparation work before the workover of the oil well is basically carried out by manpower.
