Description
Technical Field
The utility model relates to the technical field of oil pumping units, in particular to a safety protection device of an oil pumping unit.
Background
Compared with the traditional beam pumping unit, the beam pumping unit has the characteristics of long stroke and low stroke frequency. The belt traction transmission is common in the electric control reversing oil pumping machine because the belt has a wider joint surface and larger friction force. When the roller rotates, the belt is driven to rotate, so that the wellhead end and the counterweight end reciprocate up and down.
But the diameter of the steel wire rope is 30mm when the belt type pumping unit is used and the same working condition parameters such as the suspension point load of 140KN are adopted. But the belt width reaches 250mm and above. The belt type pumping unit is arranged in the field and works in severe weather throughout the year. The steel wire rope has small section, so that the steel wire rope does not have large wind resistance in windy weather. However, in the belt type oil pumping unit, due to the wide section of the belt, the belt can swing along with wind under the action of wind force, but the equipment is still running, and different shaking exists up and down each time, so that potential safety hazards are brought to the equipment and normal oil extraction.
Patent document with application number of CN201220116562.9 and named as upturning abdication windproof non-beam pumping unit discloses a non-beam pumping unit which can meet windproof requirements and does not influence the normal operation of the pumping unit due to large wind power.

The wind-proof mechanism is composed of a wind-proof cover and a wind-proof cover support arm, the wind-proof cover is arranged in front of the frame, the wellhead belt and the rope hanger are sealed, the wind-proof cover support arm is arranged at the lower end of the wind-proof cover, one end of the wind-proof cover support arm is hinged to the lower portion of the wind-proof cover, the other end of the wind-proof cover support arm is hinged to the front end of the upper platform, the upper end of the wind-proof cover is hinged to the front end of the guide wheel support arm, the frame, the wind-proof cover support arm, the wind-proof cover and the guide wheel support arm form a parallelogram, and when the guide wheel support arm overturns upwards, the wind-proof cover simultaneously leans against the frame to leave the position above the wellhead of the oil well.
In the technical scheme disclosed in the patent, the belt can receive certain pulling force under the action of the gravity of the windshield, and the belt is inconvenient to replace. When the well is repaired, after the belt is separated from the rope hanger, the belt can shrink upwards under the elastic action of the belt. After well repair is completed, the end outside the skin is positioned in the windshield, so that the belt is inconvenient to pull downwards and is connected with the rope hanger.
