Brake structure of beam pumping unit

Abstract

The invention provides a brake structure of a beam pumping unit, which ensures that the beam pumping unit rapidly stops working and further guarantees normal operation of petroleum conveying. The brake structure comprises a motor and a speed reducing box, and is characterized by further comprising an engine base, wherein the motor is located in the engine base; the speed reducing box is supported on the upper end face of the engine base; an output end of the motor is connected with an input end of the speed reducing box; a brake disc sleeves at least one side of an output shaft of the speed reducing box and is exposed out of the speed reducing box; a brake pad support is mounted on one side, corresponding to the brake disc, of the speed reducing box; a linear feeding part is fastened at the part, toward the brake disc, of the brake pad support and moves away or toward the outer end face of the brake disc; an output part of the linear feeding part is arranged toward the outer end face of the brake disc; a brake pad is fastened on the output part of the linear feeding part; and a brake region of the brake pad is arranged toward the outer end face of the brake disc.

Description

technical field [0001] The invention relates to the technical field of pumping unit structures, in particular to a brake structure of a beam pumping unit. Background technique [0002] In the existing beam pumping unit, the motor and the reduction box independently occupy a piece of land, which occupies a large area during actual operation, and the output shaft of the reduction box is directly connected to the crank structure. Emergency needs to be shut down immediately, but there is no brake structure between the existing motor and the reduction box, so the pumping unit cannot stop working quickly, resulting in subsequent adverse chain reactions, and the existing beam pumping unit can not Generally, it is arranged at the motor end. After the motor end stops, the reduction box will still rotate for a period of time. This structure still cannot ensure that the beam pumping unit stops working quickly. Contents of the invention [0003] In view of the above problems, the pre...

[0002] In the existing beam pumping unit, the motor and the reduction box independently occupy a piece of land, which occupies a large area during actual operation, and the output shaft of the reduction box is directly connected to the crank structure. Emergency needs to be shut down immediately, but there is no brake structure between the existing motor and the reduction box, so the pumping unit cannot stop working quickly, resulting in subsequent adverse chain reactions, and the existing beam pumping unit can not It is generally installed at the motor end. After the motor end stops, the reduction box will still rotate for a period of time. This structure still cannot ensure that the beam pumping unit stops working quickly.
