A beam pumping unit with heat dissipation brake structure

Abstract

The invention provides a walking beam type oil pumping unit with a heat dissipation brake structure. The whole oil pumping unit occupies a small area. A walking beam is supported on a walking beam supporting frame through a hinge seat; a horse head is arranged at the output end of the walking beam; the input end of the walking beam is connected with one end of a transmission rod on each of two sides through a rotating shaft; the other ends of the transmission rods on both sides respectively sleeve an output positioning shaft of a crank; a direct drive permanent magnet motor is supported on a machine seat; the input end of the crank sleeves two sides of an output shaft of the direct drive permanent magnet motor respectively; a brake disk sleeves one side of the output shaft of the direct drive permanent magnet motor; a brake pad support is mounted on one side, corresponding to the brake disk, of the machine seat; a linear feeding component is fastened at a position, facing the brake disk, on the brake pad support; the linear feeding component does get away or close motion towards the outer end face of the brake disk; the output part of the linear feeding component is arranged towards the outer end face of the brake disk; and a brake pad is fastened at the output part of the linear feeding component.

Description

technical field [0001] The invention relates to the technical field of pumping unit structures, in particular to a beam pumping unit with a heat dissipation brake structure. 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 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, so that the beam pumping unit often causes mechanical dam...

[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, so that the beam pumping unit often causes mechanical damage due to the failure to stop in time. failure, causing inconvenience
