Pumping unit brake structure with heat radiating function

Abstract

The invention provides a pumping unit brake structure with a heat radiating function. The pumping unit brake structure can guarantee that a beam pumping unit quickly stops working, the service life of a brake is prolonged, and normal operation of oil conveying is further guaranteed. A direct-drive permanent magnet motor is supported by a machine base, and a brake disk is arranged on one side of an output shaft of the direct-drive permanent magnet motor in a sleeving mode; a brake disk support is arranged on one side, corresponding to the brake disk, of the 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, a braking region of the brake pad is arranged towards the outer end face of the brake disk, and a ventilating assembly is arranged on one side of the brake disk support; the bottom of the ventilating assembly is fastened to the upper end face of the machine base, and an air outlet of the ventilating assembly faces the region, aligned at the brake pad, of the brake disk.

Description

technical field [0001] The invention relates to the technical field of pumping unit structures, in particular to a braking structure with heat dissipation function 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.

[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.
