Description
Technical field
The invention belongs to sensor technical field, it is related to a kind of load sensor, specifically a kind of hand-held bayonet socket sensing
Device.
Background technology
Existing bayonet type sensor, is mainly used in oilfield, and in coal bed gas and oil field in process of production, grasp is taken out
Whether the work of oil machine system is normal, and it is generally divided into fixed intersection sensor and hand-held bayonet socket sensor.Hand-held card
Oral instructions sensor is mainly used in oil field inspection and used, not high to required precision, and major requirement is light and convenient installation, existing hand
It is all to ensure installation strength with wide range to hold formula bayonet socket sensor main design thought, then amplifies microstrain signal of change force value,
It has that installation strength is whard to control, measurement accuracy is low, gather available range of signal.
The content of the invention
It is an object of the invention to provide a kind of high hand-held bayonet socket sensor of easy to install, measurement accuracy.
The purpose of the present invention can be achieved through the following technical solutions：
Neck, the biography are provided with the middle part of a kind of hand-held bayonet socket sensor, including sensor body, the sensor body
Sensor body is stuck on oil pumper pull bar by neck, and is locked by the tie down screw for being arranged on neck side；
The neck opposite side is provided with elastic portion, and the elastic portion opposite side is provided with the movable block cooperated with it, institute
State movable block and connect sensor body by two foil gauges；
There is limiter opening between the elastic portion and movable block.
Further, the elastic portion side is provided with two circular notches, and the circular trough is intraoral to be plugged with steel column, formation
Two fulcrums.
Beneficial effects of the present invention：The hand-held bayonet socket sensor that the present invention is provided, oil pumper pull bar is stuck in by neck
On, it is locked by the tie down screw of side, deformation that is thicker or attenuating occurs during using oil pumper pull bar by power, is measured
Oil pumper pull bar is changed the metering system of traditional sensors, by setting sensor limiter opening, works as locking by the size of power
Screw rod clamp when reach certain force value, limiter opening can just be closed, when solving conventional lock sensor strain regions by
Big starting force, cause the problem of sensor installation strength is difficult to control, meanwhile, reduce the range of sensor itself, significantly
The accuracy of sensor is improved, the decades of times before available range of signal is is gathered, facilitates back-end processing.
Brief description of the drawings
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the scheme of installation of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is all other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
In the description of the invention, it is to be understood that term " perforate ", " on ", " under ", " thickness ", " top ", " in ",
Indicating position or the position relationship such as " length ", " interior ", " surrounding ", are for only for ease of the description present invention and simplify description, without
It is that instruction or the signified component of hint or element must have specific orientation, with specific azimuth configuration and operation, therefore not
It is understood that as limitation of the present invention.
As shown in Figure 1-2, the invention provides a kind of hand-held bayonet socket sensor, including sensor body 1, sensor sheet
The middle part of body 1 is provided with neck 2, and sensor body 1 is stuck on oil pumper pull bar 3 by neck 2, and by being arranged on the side of neck 2
Tie down screw 4 be locked, in use, rotational lock screw rod 4 is locked in sensor body 1 on oil pumper pull bar 3, using taking out
Deformation that is thicker or attenuating, size of the measurement oil pumper pull bar 3 by power occur when oil machine pull bar 3 is by power.
The opposite side of neck 2 is provided with elastic portion 5, and when sensor body 1 is stuck on oil pumper pull bar 3, oil pumper pull bar 3 becomes
Deformation that is thick or attenuating, acts power, extrudes elastic portion 5.
The side of elastic portion 5 is provided with two circular notches 6, circular notch 6 and is plugged with steel column, forms two fulcrums, a side
Face can limit position of the oil pumper pull bar 3 in neck 2, it is to avoid skid off, on the other hand, improve the strong of the stress point of elastic portion 5
Degree, steel column is easily changed, it is to avoid because abrasion causes the problem of measurement accuracy declines during sensor long-term use.
The opposite side of elastic portion 5 is provided with the movable block 6 cooperated with it, and movable block 6 is sensed by two connections of foil gauge 7
Device body 1, when the stress of elastic portion 5 shifts, acts power to movable block 6, causes foil gauge 7 to be deformed, pass through
The collection resistance change of foil gauge 7 and the power suffered by linearly calculating oil pumper pull bar 3 with sensing amount.
There is limiter opening 8, when the tie down screw 4 of the side of sensor body 1 is being clamped between elastic portion 5 and movable block 6
When reach certain force value, limiter opening 8 can just be closed, at this moment sensor measurement microstrain when range can be made small, point
Resolution can be greatly improved, and then greatly improve the accuracy of sensor.
The hand-held bayonet socket sensor that the present invention is provided, is stuck on oil pumper pull bar by neck, passes through the locking of side
Screw rod is locked, and deformation that is thicker or attenuating occurs during using oil pumper pull bar by power, measurement oil pumper pull bar is by power
Size, change traditional sensors metering system, by setting sensor limiter opening, when tie down screw clamp when reach
Certain force value, limiter opening can just be closed, the big starting force that strain regions are subject to when solving conventional lock sensor, cause to pass
The problem of sensor installation strength is difficult to control, meanwhile, the range of sensor itself is reduced, the accurate of sensor is substantially increased
Degree, gathers the decades of times before available range of signal is, facilitates back-end processing.
In the description of this specification, the description of reference term " one embodiment ", " example ", " specific example " etc. means
