Working principle of the present utility model:
1. when slinging suspending weight, the screw pump safety guard is placed on the big flange of well head.Operator's son of checking card in safety guard, in case lift by crane out of controlly, outstanding thing will drop on above the safety guard, can not injure the person.
2. the semi-circular lower plate one (3) of safety guard and the aperture between the semi-circular lower plate two (4) closely contact with the well head sucker rod, form sealing, prevent that the card tooth from falling in the pit shaft.
3. after pump head is changed, safety guard is taken off.
Advantage of the present utility model:
The utility model volume is little, and is in light weight, easy to operate, simple and easy practicality, and the sample laboratory experiment, 15 tons of weights fall to fiercelying attack suddenly, and sample is harmless.Because guard shield safe in utilization, personal safety is protected, and the post employee dare to courageously operate, and has simplified working procedure, increases work efficiency and prevents factor such as well card accident, increases the oil well production time, increases output, is widely used in the oil recovery factory, oil field.
