Abstract
The utility model relates to the technical field of oil pumping unit detection equipment and discloses an oil pumping unit horsehead suspension point projection detection apparatus. The apparatus comprises a detection weight and a laser device which are hung on an oil pumping unit horsehead. The detection weight is a cone and the tip of the cone is provided with the laser device. A photoelectric detector formed by photodiodes is disposed on the ground exactly below the oil pumping unit horsehead. The output end of the photoelectric detector is connected with a central control device. The photoelectric detector converts received optical signals into electric signals and outputs the electric signals to the central control device. The central control device calculates the received electric signals to obtain the track of horsehead suspension point projection. Detection personnel can observe indexes of horsehead suspension point projection of a detected oil pumping unit through the central control device. The apparatus is simple in structure, accurate in detection result, and convenient to operate, and the apparatus prevents potential safety hazards during the detection process.
Description
Technical field
The utility model relates to oil pumper checkout equipment technical field, specifically a kind of pick-up unit of checking the projection of pumping unit horsehead suspension point.
Background technology
Oil pumper is the necessary equipment of production on artificial lift, and each elephant extensively adopts both at home and abroad.Oil pumper, as a kind of movable machinery, is transformed into rotatablely moving of motor the straight reciprocating motion of sucker rod by linkage assembly.Can oil pumper normal operation, whether the phenomenon of sucker rod partial wear well head can occur, and all will control by the projection of pumping unit horsehead suspension point.Therefore the measurement of horse head suspension point projection is the important testing of check before oil pumper dispatches from the factory.Suspension point projection is for a long time all by check through hole or adopts the mode of 2 transit combined measurements to carry out, while utilizing check through hole to check, for guaranteeing weight line, do not encounter check through hole, need to constantly adjust its position, operating process is complicated, precision is not high, testing process also exists certain potential safety hazard.
Utility model content
The purpose of this utility model is to provide a kind of pumping unit horsehead suspension point projection pick-up unit, the problem that while adopting theodolite testing in the prior art to solve, operating process is complicated, accuracy of detection is not high.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows:
A kind of pumping unit horsehead suspension point projection pick-up unit, it comprises check weight, the laser instrument being suspended on pumping unit horsehead, described check weight is cone, the cone tip of described check weight is provided with laser instrument, on ground under described oil pumper burner, be placed with the photoelectric detector being comprised of photodiode, the output terminal of described photoelectric detector is connected with central control unit.
Laser instrument is arranged on to the cone tip of check weight in the utility model, the launching site of laser instrument and the cone tip of check weight are synchronized with the movement, can guarantee that launched laser and weight line coincide; In relevant position, ground, place the luminous point that photoelectric detector receives laser instrument transmitting, photoelectric detector is transferred to central control unit after light signal is converted into electric signal, by central control unit, received electric signal is calculated, calculate the track of horse head suspension point projection.
As further improvement of the utility model, a plurality of photodiodes in described photoelectric detector are according to rectangular arranged.
The beneficial effects of the utility model: by the use of laser instrument and photoelectric detector, make the detection of pumping unit horsehead suspension point projected footprint realize robotization detection, testing staff just can observe the index that is verified the projection of pumping unit horsehead suspension point by central control unit, the utility model is simple in structure, easy to operate, testing result is accurate, has avoided the potential safety hazard in testing process.
