Abstract
The utility model relates to a detection apparatus and particularly relates to a laser detector for a scissors difference between cranks of an oil pumping unit. The laser detector is composed of a marking machine and a holding machine. The marking machine is composed of a rack marking rod erected on a first magnetic support and a laser marker vertically hinged to the rack marking rod. The holding machine is composed of a rack holding rod erected on a second magnetic support and a holding ruler longitudinally fixed on the rack holding rod. According to the laser detector, two components are firmly adsorbed at two ends of the ranks by using magnetic flux switches which controls magnetic flux, and the scissors difference between the cranks of the oil pumping unit is determined qualified or not based on a value indicated by the reading of the laser maker, and thus measurement efficiency and precision are raised further.
Description
Technical field
The utility model relates to pick-up unit, relates in particular to a kind of oil pumping machine crank price scissors laser detecting apparatus.
Background technology
Oil pumping machine crank is the curved bar of two parallel coaxial.Because for a long time work, the friction that two cranks are subject to and extent of corrosion different are departed from the center of gravity line of two cranks, have produced price scissors; The generation of price scissors can cause counterweight of oil pumping unit inhomogeneous, and then damages oil pumper.Thereby the measurement of oil pumping machine crank price scissors is the line service in oil field, and measuring method roughly to have two kinds be ruler method and wear method of principal axes.Ruler method is measured when installing and overlap the crank two ends larger error can occur, the one, the length of ruler has strengthened measuring error, the 2nd, also there is error in the straight degree of ruler itself, especially more easily occurs error when clearance gauge is used in conjunction with, and more its precisions of the measuring tool of use are poorer.And it is not easy to operate to wear method of principal axes, and error rate is large.
The utility model content
The utility model is intended to for the deficiency that exists in the background technology, and a kind of oil pumping machine crank price scissors laser detecting apparatus is provided.
In order to address the above problem, the utility model adopts following technical scheme:
Oil pumping machine crank price scissors laser detecting apparatus of the present utility model, by marking machine with mechanism is become, described marking machine be by stood the frame mark post on the first magnetic engine base and on the frame mark post vertical hinged cursor pen consist of; Machine by having stood the frame barre on the second magnetic engine base and on the frame barre, vertically having fixed chi to be consisted of.
As further improvement of the utility model, the first magnetic engine base has identical geometric configuration with the second magnetic engine base, and identical level and smooth support bottom surface.
As further improvement of the utility model, frame mark post and frame barre are the cylindricality bodies of rod with same geometry, and the emitting head of cursor pen is corresponding with the index dial chi.
As further improvement of the utility model, the first magnetic engine base and the second magnetic engine base all have built-in magnetic patch, are respectively equipped with magnetic switch I and the magnetic switch II of control magnetic flux at the shell of its support.
As further improvement of the utility model, marking machine with support on same base station I, the light point that the cursor pen is launched hits 0 position of the scale on the chi.
As further improvement of the utility model, marking machine with machine is respectively located in crank I that oil pumper cranks arm and crank II on, the line at its two seat is vertical in cranking arm, the light point of cursor pen emission hits the scale on the chi.
As further improvement of the utility model, described cursor pen is to be replaced by the color laser transmitter.
A kind of oil pumping machine crank price scissors laser detecting apparatus of the present utility model, reasonable in design has reduced measuring error by laser detection, and simple to operate, thereby reaches the purpose of increasing work efficiency with measuring accuracy.

Structural representation when Fig. 2 is the utility model measurement.
Embodiment
Below in conjunction with accompanying drawing 1 and 2 pairs of a kind of oil pumping machine crank price scissors laser detecting apparatus of the present utility model of accompanying drawing, be described further:
Oil pumping machine crank price scissors laser detecting apparatus of the present utility model consists of by marking machine 1 with machine 2, marking machine 1 be by stood frame mark post 4 on the first magnetic engine base 3 and on frame mark post 4 vertical hinged cursor pen 5 consist of; Machine 2 by having stood frame barre 7 on the second magnetic engine base 6 and on frame barre 7, vertically having fixed chi 8 to be consisted of.Described the first magnetic engine base 3 has identical geometric configuration with the second magnetic engine base 6, and identical level and smooth support bottom surface; Frame mark post 4 and frame barre 7 are the cylindricality bodies of rod with same geometry, and the emitting head of cursor pen 5 is with corresponding the index dial of chi 8.At the first magnetic engine base 3 and the second magnetic engine base 6 built-in magnetic patch is arranged all, be respectively equipped with magnetic switch I 9 and the magnetic switch II 10 of control magnetic flux at the shell of its support.
Before the measurement, the calibration of making zero first.Be about to marking machine 1 with 2 in machine on same base station I 11, the light point that cursor pen 5 is launched hits and 0 position of chi 8 high scales is qualified, can use after making zero if non-return-to-zero will be adjusted, as shown in Figure 1.
During measurement, with marking machine 1 with machine 2 is respectively located in crank I 12 that oil pumper cranks arm and crank II 13 on, the line at its two seat is vertical in cranking arm, the light point of cursor pen 5 emission hits on the scale of chi 8, by the numerical value of the point that shines at the cursor pen 5 that chi 8 is read, as shown in Figure 2.This device as required, its cursor pen 5 is to be replaced by the color laser transmitter.
