Background technology
In the petro-technology field, load-position diagram is the main test data of diagnosis rod-pumped well operating mode, and load-position diagram is made of with corresponding suspension point displacement polished rod load in the jig frequency process.The technology of test oil pumper suspension point displacement now mainly contains: 1, adopt the backguy method test suspension point displacement of indicator.Spool is arranged in the indicator, twine nylon wire on the spool, during the pulling nylon wire, spool rotates, and by spool rotation metering backguy length, thereby converses the suspension point displacement.This method can be used when artificial process is tested load-position diagram, and automatism is relatively poor, because the reciprocal access times of nylon wire can only reach tens thousand of times, is not suitable for long-term online use.2, acceleration transducer method.At suspension point acceleration transducer is installed, by test suspension point acceleration, is obtained the suspension point displacement through twice pair of time integral conversion.This method can be used for long-term on-line testing, but the acceleration test numerical discretization is bigger, and is more discrete behind twice integration, data reliability and poor repeatability.3, angular speed method.Angular displacement sensor is installed on the oil pumper walking beam, and the walking beam angular displacement that obtains by test be multiply by the walking beam forearm length and is converted and obtain the suspension point displacement.This method can be used for long-term on-line testing, but the inclination angle of angular displacement sensor relies on the acceleration of gravity in the sensor to produce, and angular displacement test number discreteness is bigger, the suspension point displacement data reliability and the poor repeatability that convert and obtain.This shows that traditional technology is not suitable for the measurement of the unattended oil well suspension point of robotization displacement.
The utility model content
The utility model exists automatism relatively poor at existing oil pumper suspension point displacement measurement technology, be not suitable for long-term on-line testing, the measurement data discrete type is relatively poor, cause load-position diagram can not accurately reflect the present situation of oil pumper operating mode in real time, provide a kind of for the angular displacement improved method of measuring oil pumper suspension point displacement measuring device, the angular displacement signal that this method records is stable, and discreteness is little, the automaticity height can be used for long-term on-line testing.
The technical solution of the utility model is: a kind of oil pumper suspension point displacement measuring device, comprise angular displacement sensor, this device also comprises stationary installation, wheelwork and PC, stationary installation comprises fixedly connected end face holding clamp and end face absorption magnet steel, with the oil pumper support shaft fixedly end face link to each other, wheelwork comprises fixedly connected rotating shaft absorption magnet steel and rotating shaft holding clamp, link to each other with the oil pumper support shaft, described angular displacement sensor comprises rotation axis, stiff end and signal output part, rotation axis links to each other with the rotating shaft holding clamp, stiff end links to each other with end face absorption magnet steel, and signal output part links to each other with PC.
Preferably: angular displacement sensor comprises that stiff end is firm banking, links to each other with end face absorption magnet steel by firm banking.
Preferably: angular displacement sensor rotation axis and oil pumper support shaft axle center are at same straight line.
The beneficial effects of the utility model are: (1) the utility model produces sensor and forces to rotate by with relatively rotating between the support shaft of oil pumper walking beam swing and the support, records rotational angle, and discrete type is little, signal stabilization, and data are reliable.(2) the utility model angular displacement sensor rotation axis and oil pumper support shaft axle center are at same straight line, and angular displacement sensor is fixed by firm banking, has better guaranteed the angular displacement sensor stationkeeping, avoid angular displacement sensor axle generation deformation.(3) the utility model carries out the automatic calculating of angular displacement data and suspension point displacement by PC, and the automatization level height is applicable to long-term on-line testing.

Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in more detail below in conjunction with accompanying drawing.
A kind of oil pumper suspension point displacement measuring device, comprise angular displacement sensor 1, also comprise stationary installation, wheelwork and PC, stationary installation comprises fixedly connected end face holding clamp 2 and end face absorption magnet steel 3, wheelwork comprises fixedly connected rotating shaft holding clamp 4 and rotating shaft absorption magnet steel 5, angular displacement sensor 1 comprises rotation axis, stiff end 6 and signal output part, rotation axis links to each other with rotating shaft holding clamp 4, stiff end links to each other with end face absorption magnet steel, signal output part links to each other with PC, the stiff end 6 of angular displacement sensor 1 is firm banking, links to each other with end face absorption magnet steel by firm banking.
During installation, stationary installation by end face absorption magnet steel 3 and oil pumper support shaft fixedly end face link to each other, by end face holding clamp 2 with stationary installation and oil pumper support shaft fixedly end face further fix, wheelwork links to each other with the oil pumper support shaft by rotating shaft absorption magnet steel 5, and by rotating shaft holding clamp 4 wheelwork and oil pumper support shaft are further fixed, the angular displacement sensor rotation axis links to each other with rotating shaft holding clamp 4 and guarantees that oil pumper support shaft axle center is at same straight line.
During work, the oil pumper support shaft rotates with the walking beam swing, support shaft and support shaft fixedly produce relative rotation between the end face, because wheelwork and angular displacement sensor 1 rotation axis rotate with support shaft, angular displacement sensor 1 will record oil pumper support shaft rotational angle signal, and it is converted into voltage value signal output, this output signal is delivered to long-range PC, directly automatic conversion of the output signal of angular displacement sensor 1 is drawn the displacement of oil pumper suspension point by the conversion software on the PC.This mode is forced to rotate with support shaft by angular displacement sensor 1 and is recorded angle signal, and signal stabilization is strong, and discreteness is little, and suspension point displacement data precision and the reliability that obtains that convert will improve greatly.
