Embodiment Construction

[0040] In order to make the principles, technical solutions and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0041] figure 1 A schematic structural view of a pumping unit provided in the embodiment of the present application, such as figure 1 As shown, the pumping unit 0 includes: a pumping unit donkey head 01 and a polished rod 02, and a pumping unit braid 03 (usually a steel rope) connecting the pumping unit donkey head 01 and the polished rod 02.

[0042] The donkey head 01 of the pumping unit pulls the polished rod 02 to move up and down through the braid 03 of the pumping unit, so that the polished rod 02 repeatedly enters and exits the oil well to extract the oil in the oil well.

[0043] However, the working environment of the pumping unit is relatively harsh, which causes the braids of the pumping unit to be easily worn and...

Abstract

The application discloses an oiling device, which belongs to the technical field of machinery. The oiling device includes: a connected moving structure and an oiling structure; the moving structure is used to move along the braid of the pumping unit; the oiling structure is used to move along the The braids of the oil pumping machine are moved, and the surface of the braids of the oil pumping unit is oiled. The application can solve the problem that the probability of normal operation of the pumping unit is low, and the application is used for oiling the surface of the braid of the pumping unit.

Description

technical field [0001] The present application relates to the field of mechanical technology, in particular to an oiling device. Background technique [0002] The pumping unit is a relatively common equipment in the petroleum industry. [0003] The pumping unit is composed of multiple parts, and the multiple parts cooperate with each other to extract the underground oil. Exemplarily, the plurality of components include the donkey head and the polished rod of the pumping unit, and the braid of the pumping unit connecting the donkey head and the polished rod. The donkey head of the pumping unit pulls the polished rod to move up and down through the braid of the pumping unit, so that the polished rod repeatedly enters and exits the oil well to extract the oil in the oil well. [0004] However, the working environment of the pumping unit is relatively harsh, which causes the parts (such as the braids of the pumping unit) of the pumping unit to be easily worn and corroded, ther...
