Abstract
A bayonet type polished rod dynamic load sensor consists of a clamping bolt, a measuring body, a strain amplifying device, and a signal processing and communication module; wherein the clamping body 1 is arranged in the measuring body 2; the strain amplifying device is arranged at a corner of the measuring body, and adopts a single bridge or double bridge structure; the signal processing and communication module is connected with the strain amplifying device. According to the bayonet type polished rod dynamic load sensor of the utility model, the measuring body is fixed on a polished rod through the clamping bolt, tiny deformation of the diameter of the polished rod is transmitted to a host through the strain amplifying device and the signal processing and communication module, therefore, the bayonet type polished rod dynamic load sensor needs not to be arranged between clamping plates of a polished rod eye, i.e., risk for installing the polished rod eye does not exist; at the same time, the bayonet type polished rod dynamic load sensor of the utility model is light in weight, and is convenient in installation, in addition, the strain amplifying device adopts the single bridge or double bridge structure, thus the bayonet type polished rod dynamic load sensor also has a high precision.
Description
Technical field: the utility model relates to a kind of sensor, and especially a kind of bayonet type dynamic load sensor for polish rod belongs to the oil field surveying instrument.
Background technology: in the production test procedure in oil field, load-position diagram provides important data for the working condition of oil pumper, so the surveying instrument of load-position diagram enjoys attention.Commonplace measuring method is that load transducer is packed between two clamping plate of poliched rod eye at present.This measuring method need to be stopped well and need to be with oil pumping machine unloading and then installed load sensor.In measuring process, need unloaded loads, complicated operation, the data drift is large, and has potential safety hazard during unloading load.
Summary of the invention: for above-mentioned the deficiencies in the prior art, it is a kind of lightweight, easy for installation that the utility model provides, the bayonet type dynamic load sensor for polish rod that precision is high.
For achieving the above object, the technical solution adopted in the utility model is: the bayonet type dynamic load sensor for polish rod is comprised of fishbolt, measurement body, strain multiplying arrangement and signal processing and communication module.Fishbolt 1 is installed in to be measured in the body 2, and the strain multiplying arrangement is arranged on one jiao that measures body, adopts single bridge or double-bridge structure.Signal processing and communication module are connected with the strain multiplying arrangement.
Measurement body of the present utility model is fixed on the polished rod by fishbolt.The miniature deformation of polished rod diameter processes by strain multiplying arrangement, signal and communication module reaches main frame.Needn't be installed in the poliched rod eye clamping plate, the risk that poliched rod eye is installed does not just exist.The utility model is lightweight, easy for installation simultaneously, and the strain multiplying arrangement adopts single bridge or double-bridge structure, and precision is high.
Description of drawings
Fig. 1 is the synoptic diagram that the strain multiplying arrangement adopts double-bridge structure.
Fig. 2 is the synoptic diagram that the strain multiplying arrangement adopts single bridge construction.
Embodiment:
As shown in Figure 1, the bayonet type dynamic load sensor for polish rod is comprised of fishbolt 1, measurement body 2, strain multiplying arrangement 3 and signal processing and communication module 4.Fishbolt 1 is installed in to be measured in the body 2, by fishbolt 1 this instrument is fixed on the polished rod 5.Strain multiplying arrangement 3 is arranged on one jiao that measures body 2, adopts double-bridge structure.Signal is processed and communication module 4 is connected with strain multiplying arrangement 3.
As shown in Figure 2: the strain multiplying arrangement adopts single bridge construction.
Claims (1)
