Multifunctional brake structure for oil pumping unit

Abstract

The invention provides a multifunctional brake structure for an oil pumping unit. The multifunctional brake structure can guarantee that a beam pumping unit quickly stops working, and normal operation of oil conveying is further guaranteed. A brake disk is arranged on one side of an output shaft of a direct-drive permanent magnet motor in a sleeving mode; a brake disk support is arranged on one side, corresponding to the brake disk, of a machine base; a linear feeding component is fastened to the position, facing the brake disk, of the brake disk support; the linear feeding component can move away from or close to the outer end face of the brake disk, the output portion of the linear feeding component is arranged towards the outer end face of the brake disk, a brake pad is fastened to the output portion of the linear feeding component, and a braking region of the brake pad is arranged towards the outer end face of the brake disk; a locking piece is arranged on the end face, close to the linear feeding component, of the brake pad; the locking piece can extend to a place right above the upper end face of the linear feeding component when the locking piece is in a shrinking state, and a through locating hole is formed in the locking piece. The multifunctional brake structure further comprises a locking sleeve which is fixedly arranged on the upper end face of the linear feeding component.

Description

technical field [0001] The invention relates to the technical field of pumping unit structures, in particular to a multifunctional brake structure of the 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 prob...

[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.
