Abstract
The utility model relates to a bayonet type polished rod load sensor. Mainly solves the problem of the safety of operators. The method is characterized in that: a fastening bolt (1) penetrates through the shell (8), a fixing groove (10) is formed in one end, located in the shell (8), of the fastening bolt (1), and a polished rod (7) is clamped in the groove (10); the device (2) for amplifying the variable changes in the shell (8) is sequentially connected with the micro variable sensor (3) and the signal processing and communication module (4), and the signal processing and communication module (4) is connected with the acceleration sensor (5) and the microcomputer collector (6) outside the shell (8). The instrument has the advantages of convenience, storage and safe operation.
Description
Technical field:
The utility model relates to the oilfield test field, particularly a kind of bayonet type polished rod load sensor.
Background technology:
The oil field for whether the work of grasping pumping unit system is normal, often adopts measurement of power figure to monitor in process of production.Need load removal in when test, complicated operation, and the data drift is big, the potential safety hazard that exists during unloaded is serious, as: sensor slippage, fall that " horse head ", poliched rod eye twine, fault such as the stay cord of direction finder freezes winter easily; Need 3 to 4 testers to cooperate with regard to existing well site situation, the tester need climb to unloaded on the X-tree, has potential safety hazard.
The utility model content:
In order to solve the deficiency that there is security hidden trouble in prior art, the utility model provides a kind of bayonet type polished rod load sensor, and this instrument has conveniently, the advantage of handling safety.
The purpose of this utility model is achieved by the following technical solution: have the bolt of confinement to pass on this Instrument shell, and confine the end fixed groove that bolt is positioned at housing, have polished rod to be blocked by two stuck points in the groove; Have the deformation multiplying arrangement to connect miniature change sensor, signal Processing and communication module successively in the housing, and signal Processing and communication module connect acceleration transducer and the outer micro computer collector of housing.
The utlity model has following effect: owing to adopted technique scheme, this instrument is confined bolt and is blocked polished rod 7 through spill housing and stuck point, do not need the tester to climb up the X-tree unloaded, the sensor slippage promptly can not occur, fall faults such as " horse head ", poliched rod eye winding, the problem of potential safety hazard more can not occur; And the micro computer collector has the memory function of pair data.
Description of drawings:
Accompanying drawing 1 is a bayonet type polished rod load sensor construction block diagram of the present utility model.
In the accompanying drawing: 1-has indication to confine bolt, 2-deformation multiplying arrangement, the little changing sensor of 3-, 4-signal Processing and communication module, 5-acceleration transducer, 6-micro computer collector, 7-polished rod, 8-housing, 9-stuck point, 10-groove.
Embodiment:
Below in conjunction with embodiment the utility model is further described:
As shown in Figure 1, this instrument is confined bolt 1 and is blocked polished rod 7 through spill housing 8, also can block polished rod 7 better by 2 stuck points 9 in the groove 10 as required, as long as promptly be that operating personnel block polished rod 7 with this housing 8 and can install this device, not resembling several personnel of present Technology Need is installed to testing apparatus on the oil pumper, even also to climb up the X-tree unloaded, as seen this device the sensor slippage can not occur, fall " horse head ", faults such as poliched rod eye winding, more potential safety hazard can not appear, thereby improved processing safety, convenient and swift, save manpower and man-hour, thereby enhance productivity; Connect miniature change sensor 3, signal Processing and communication module 4 successively by deformation multiplying arrangement 2 in the housing 8, and signal Processing and communication module 4 connect the micro computer collector 6 outside acceleration transducer 5 and the housing 8, and the micro computer collector has the memory function of pair data again.
During concrete operations, as shown in Figure 1, energized at first, then this instrument by being arranged, indication confinement bolt 1 card and stuck point 9 is stuck on the oil-extractor polish-rod 7, oil pumper is started working, because pulling force, polished rod 7 produces miniature deformation, because deformation is small, thus deformation quantity multiplying arrangement 2 adopted, after little changing sensor 3 collects polished rod 7 deformation signals, the output digital signal, deliver signal Processing and communication module 4, conversion deformation variable quantity is the tension variations amount, the built-in acceleration transducer 5 of bayonet socket sensor, the acceleration of displacement is delivered signal Processing and communication module 4, the conversion acceleration amount is a displacement, is sent in the micro computer collector 6 storage data and apparent load-position diagram curve after the data rough handling.
Claims (3)
1, a kind of bayonet type polished rod load sensor comprises housing (8), it is characterized in that: have confinement bolt (1) to pass on the housing (8), and confine the end fixed groove (10) that bolt (1) is positioned at housing (8), have polished rod (7) to be stuck in the groove (10); Have deformation multiplying arrangement (2) to connect miniature change sensor (3), signal Processing and communication module (4) successively in the housing (8), and signal Processing and communication module (4) connect acceleration transducer (5) and the outer micro computer collector (6) of housing (8).
2, bayonet type polished rod load sensor according to claim 1 is characterized in that: polished rod (7) blocks by the some stuck points (9) in the groove (10).
