Embodiment Construction
[0028] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.
[0029] The purpose of this specific embodiment is to provide a pumping unit and its donkey head centering control device, which solves the need to repeatedly climb the donkey head of the pumping unit for high-altitude operations to adjust the donkey head centering, and there are potential safety hazards; the top wire is exposed for many years There will be rust problems when exposed to wind and rain outside.
[0030] Hereinafter, an embodiment will be described wit...

The invention discloses an oil pumping machine and a horsehead centering control device thereof. The horsehead centering control device of the oil pumping machine comprises an operation rod rotatablyarranged at the lower end of a walking beam in the length direction of the walking beam, and a jack screw arranged between two lateral panels of the horsehead in the vertical direction of the operation rod and is used for pushing the horsehead to move. The operation rod is in transmission connection with the jack screw by a gear transmission mechanism. In this way, the horsehead centering controldevice of the oil pumping machine is located on an oil pumping machine operation platform, operators stand on the oil pumping machine operation platform and rotate the operation rod to drive the jackscrew to move and push the horsehead to correspondingly move to two sides to achieve the aim of centering, and operation is convenient. The jack screw located between the two lateral panels to avoid rust and corrosion caused by being exposing to wind and rain, and therefore the problem of potential safety hazard caused by climbing the horsehead of the oil pumping machine to work high above the ground to adjusting centering of the horsehead is solved, and the problem of rust and corrosion caused by the jack screw being exposing to wind and rain for years is solved.
Description
technical field [0001] The invention relates to the technical field of oil recovery in oil fields, and more specifically relates to a pumping unit and a donkey head centering control device thereof. Background technique [0002] Enterprise standard Q / SY DQ0919-2016 stipulates in 3.1.3 of the production facilities management regulations of oil and water well metering room that the center of donkey head, rope hanger and packing box of pumping unit should reach three points and one line, that is, centering, and the error should be less than 22mm. Qualified, the error is greater than 25mm is not allowed to run. It is required that the polished rod does not wear the anti-blowout box, the suspension rope does not wear the edge of the donkey head, and the left and right are symmetrical. At present, the center of the donkey head, rope hanger and packing box of the pumping unit reaches three points and one line. The adjustment effect depends on the top wires on both sides of the don...
