Abstract
The utility model relates to a force-measuring sensor, used for various monitoring of force and torque of the industries of petroleum, chemical engineering, etc. The external shape of the sensor is of a set screw cylinder structure, an induction head is arranged at the front end of the cylinder, a monitoring body is pasted on the inner side of the induction head, the main body of the cylinder is a hollow body, the diameter of the through hole of the hollow body is 6-25 mm, a signal line is connected with the joint of a lead wire through the center bore of the main body of the cylinder, and the joint of the lead wire is connected with root part of the main body of the cylinder through screw thread. Compared with the existing force-measuring sensors, the utility model has the advantages of convenient installation and high measurement accuracy.
Description
The utility model relates to a kind of force cell, is applicable to the multiple power of oil, chemical industry and other industries, the monitoring of moment.
Oil and gas well drilling engineering turntable torque monitoring generally adopts force cell at present, its force cell is that pancake is divided body structure, during installation, force cell is fixed on the front end of rotating disk jackscrew by pallet, TORQ monitor by the Zhongyuan Oil Field development belongs to this structure (patent No. is 91202815.7) though this measurement structure ratio Communication for Torque Sensor ' in the past is significantly improved, but volume is big, and when installing still is cumbersome, its reason is a lot of drill crews tourist buses, well head is not on same vertical line, cause the rotating disk dislocation, the support and the rotating disk range distribution inequality of jackscrew are installed, the force cell mounting distance is not enough, during installation, also need cut, weldering jackscrew support, workload is very big.
The purpose of this utility model is to overcome that existing force cell is installed problem such as inconvenience and the force cell of the rotating disk jackscrew cylindrical structure form that designs can directly substitute jackscrew and play fixedly rotating disk and dynamometry effect, and install very convenient.
The purpose of this utility model is achieved in that the utility model force cell mainly is made of inductive head, monitoring body, cylindrical body and pigtail splice, its profile is the jackscrew cylindrical structure, be provided with inductive head at the cylindrical body front end, the inductive head inboard is pasted with the monitoring body, cylindrical body is a hollow body, its through-hole diameter is at 6～25 millimeters, and signal lead joins by cylindrical body central through hole and pigtail splice, and pigtail splice is by being threaded in the root of cylindrical body.
This practical institute type force cell is not only installed very convenient, has higher measuring accuracy simultaneously, the continuous several mouthfuls of well service tests through the scene, and effect is remarkable.
Accompanying drawing is the utility model structural representation.
Below in conjunction with accompanying drawing the utility model is further described:
The utility model force cell mainly is made up of inductive head 1, monitoring body 2, signal wire 3, cylindrical body 4 and pigtail splice 5, cylindrical body is a hollow body, its through-hole diameter is between 6～25 millimeters, and signal wire 3 passes through this center pit, and joins with pigtail splice 5; Inductive head 1 closely cooperates with cylindrical body 4 tops and is tightly connected, and inductive head 1 inboard is pasted with monitoring body 2; Pigtail splice 5 is by the root of screwed connection at cylindrical body.
During use, unload the jackscrew of lower rotary table both sides, load onto force cell, and add prestress, when creeping into, drilling rod reactive torque power and chain pull act on the force cell, the force cell output signal by cable to secondary list processing (LISP), amplification, then show, record, finish dynamometry work, its measuring accuracy is higher.
