Abstract
The utility model relates to a pumping well polish rod damping device which is placed between a beam hanger of a pumping unit and a loading square clamp. The pumping well polish rod damping device comprises a damping spring and a protective pipe, wherein the damping spring and the protective pipe are placed on a pumping well polish rod in a sleeved mode, the top of the damping spring is contacted with the loading square clamp, the lower portion of the damping spring is arranged in the protective pipe in a sleeved mode, and the protective pipe is placed on an upper end face of the beam hanger in a sitting mode. By means of the pumping well polish rod damping device, the phenomenon that the beam hanger bumps the loading square clamp can be effectively avoided, the times of production accidents can be reduced, and a practical effect of prolonging service life of the loading square clamp and the pumping well polish rod is achieved. The pumping well polish rod damping device is reasonable in structural design, convenient to use and reliable in property.
Description
Technical field
The utility model relates to a kind of oil production equipment auxiliary technical field, particularly a kind of pumping well polish rod damping device.
Background technology
Pumping well polish rod is the vitals of rod-pumped well, is a sucker rod producing the roofbolt topmost, is used for carrying the weight of fluid column in whole roofbolts and the pit shaft, and the sucker rod of it and bottom is threaded connection.Can cause the descending hysteresis of polished rod or rest on a certain position during thick or pump card when thermal production well oil, and when up can clash load side's clamp at polished rod top of the polished rod eye of oil pumper, the side's of causing clamp is knocked or is made away the production accidents such as pumping rod disengaging of polished rod and bottom easily, has had a strong impact on the efficient of extraction operation.
The utility model content
The purpose of this utility model provides a kind of phenomenon that can effectively avoid polished rod eye bump load side clamp, the generation of minimizing production accident, the pumping well polish rod damping device in the side's of prolongation clamp and polished rod application life.
Realize that the technical scheme that the purpose of this utility model is taked is: this device is arranged between the polished rod eye and the side's of load clamp of oil pumper, formed by the damping spring and the pillar that are sleeved on the pumping well polish rod, wherein, the top of damping spring contacts with load side's clamp, the bottom is sleeved in the pillar, and pillar is sat the upper surface of putting at polished rod eye.
Described damping spring is when inactive state, and the exposed parts that stretches out pillar is 10cm～20cm.
According to the pumping well polish rod damping device that such scheme is made, can effectively stop the phenomenon of polished rod eye bump load side clamp, reduce thus the generation of production accident, reach the practical function in prolongation load side's clamp and pumping well polish rod application life.This apparatus structure is reasonable in design, and is easy to use, dependable performance.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, pumping well polish rod damping device of the present utility model is arranged between the polished rod eye 6 and the side's of load clamp 4 of oil pumper, formed by the damping spring 1 and the pillar 2 that are sleeved on the pumping well polish rod 3, wherein, the top of damping spring 1 contacts with load side's clamp 4, the bottom is sleeved in the pillar 2, and pillar 2 is sat the upper surface of putting at polished rod eye 6.Described damping spring 1 is when inactive state, and the exposed parts that stretches out pillar 2 is 10cm～20cm.Label 5 is polished rod eye lifting ropes.In the oil pumper course of work, when the oil pumper down stroke, it is descending that pumping well polish rod 3 is followed polished rod eye 6, and when the oil pumper up stroke, load side's clamp 4 compressions on the descending pumping well polish rod 3 are the damping spring 1 of operation upwards, make fierce impact force become slowly elastic deformation, when damping spring 1 a compressed half, load on the pumping well polish rod 3 just is delivered on the pillar 2, thereby can effectively avoid the phenomenon of polished rod eye 6 bump load side clamps 4, and can reduce the generation of production accident, prolong the application life of load side's clamp 4 and pumping well polish rod 3.
