the technical solution of the utility model is achieved in that
a kind of bailing formula pumping-unit workdone graphic testing arrangement of the present utility model is, this device comprises derrick panel, and derrick panel one end is provided with large pulley, and on large pulley, cover has flexible rod, flexible rod one end is connected with down-hole relevant device, and the flexible rod other end and reel are intertwined and connected; Described derrick panel is provided with mounting bracket, and mounting bracket end face is provided with load test wheel, and load test wheel both sides are respectively equipped with displacement measurement wheel and contact roller; Load test wheel is positioned to roll below flexible rod and with flexible rod and is connected, and rolls and is connected above displacement measurement is taken turns and is positioned at flexible rod with contact roller with flexible rod.
in aforementioned means, in the race of described load test wheel, be uniformly distributed with one group of pressure sensor along the circumference.
in aforementioned means, the outer rim of described displacement measurement wheel is uniformly distributed with one group of magnet pair along the circumference, the polarity cross-distribution that one group of magnet is right; Displacement measurement wheel side is provided with hall device.
in aforementioned means, described displacement measurement wheel is connected with mounting bracket end face with contact roller, the race peak that displacement measurement is taken turns and the race minimum point of contact roller is taken turns lower than load test.
in aforementioned means, the axis being parallel of described mounting bracket end face and flexible rod.
owing to have employed technique scheme, compared with prior art, the utility model successfully solves because bailing formula oil pumper does not have polished rod eye cannot install the technical problem of indicator diagram measurement equipment the utility model, can facilitate the analysis of oil well condition.Adopting the utility model to improve bailing formula oil pumper, without the need to changing existing bailing formula oil pumper, therefore can not produce any adverse effect to the work of existing bailing formula oil pumper.Only need to install a set of checkout gear on existing derrick panel, checkout gear is not by the impact of large pulley both sides flexible rod angle; Need not unclamp flexible rod two during installation, flexible rod only need be allowed to be in relaxed state can be clamp-oned flexible rod in the race of the displacement measurement wheel of checkout gear, load test wheel and contact roller, installs very convenient, can construct at the scene.Apparatus structure of the present utility model is simple, and improvement cost is low.During if do not needed, only checkout gear need be removed, restorative good.The utility model can widely use on existing bailing formula oil pumper, has dissemination.

Detailed description of the invention
below in conjunction with drawings and Examples, the utility model is described in further detail, but not as to any restriction of the present utility model.
Embodiment
the utility model is constructed by a kind of following method of installing indicator diagram testing device on bailing formula oil pumper, as shown in Figure 1, the method is on the derrick panel 1 of bailing formula oil pumper, fix a mounting bracket 4, mounting bracket 4 end face is parallel with flexible rod 3, then fix load test wheel 5 and a displacement measurement wheel 6 at mounting bracket 4 end face, and make flexible rod 3 successively bottom displacement measurement wheel 6 and load test take turns above in the of 5 through being wrapped in the cylinder that is connected with motor (cylinder does not draw); The drag load F of flexible rod 3 is calculated by the radial pressure F1 measuring flexible rod 3 pairs of load test wheels 5; The displacement L of flexible rod is calculated by the rotation number of turns measuring displacement measurement wheel 6; And utilize the displacement L of flexible rod 3 and drag load F to draw the indicator card of oil well.Load test wheel 5 to be positioned in the middle part of mounting bracket 4 end face and by flexible rod 3 upwards jack-up; Described displacement measurement wheel 6 is positioned at load test and takes turns 5 sides and by flexible rod 3 to pressing down; Load test is taken turns 5 opposite sides and is provided with contact roller 7 and makes flexible rod 3 produce as shown in Figure 1 bending at load test wheel place thus form radial pressure F1 on load test wheel.The wheel trench bottom of load test wheel 5 is evenly equipped with pressure sensor (not shown in FIG.), is measured the radial pressure F1 of flexible rod 3 pairs of load test wheels 5 by pressure sensor; Calculate the drag load F of flexible rod by radial pressure F1, on load test wheel 5 by force vector as shown in Figure 2, the drag load F formula of flexible rod can be derived according to Fig. 2 and Triangle Formula:
F=F1÷（2×cosθ）

θ is the angle that radial pressure F1 and displacement measurement take turns between side draw load F.This definite value of angle theta after displacement measurement wheel 6, load test wheel 5 and contact roller 7 position are determined, drag load F is the stressed equalization of various piece in the middle of flexible rod.
described displacement measurement wheel is uniformly distributed with one group of magnet pair along the circumference, the polarity cross-distribution that one group of magnet is right, by being located at the alternately change frequency n of the hall device identification magnet polarities of displacement measurement wheel side, thus draw the number of turns that wheel rotates forward or backwards, and calculate the displacement L of flexible rod as follows:
L=2（R+r）nπ÷z
in formula: R is the radius (for definite value) of displacement measurement wheel,
r is the radius (for definite value) of flexible rod,
n is the alternately change frequency (measured value) of magnet polarities,
z is that magnet is to quantity (for definite value).
described indicator card is drawn according to the displacement L of the drag load F calculated and flexible rod.
according to of the present utility model a kind of bailing formula pumping-unit workdone graphic testing arrangement that said method is formed, as shown in Figure 1, this device comprises derrick panel 1, derrick panel 1 one end is provided with large pulley 2, on large pulley 2, cover has flexible rod 3, flexible rod 3 one end is connected with down-hole relevant device, and flexible rod 3 other end and reel are intertwined and connected; Described derrick panel 1 is provided with mounting bracket 4, and mounting bracket 4 end face is provided with load test wheel 5, and load test is taken turns 5 both sides and is respectively equipped with displacement measurement wheel 6 and contact roller 7; Load test wheel 5 is positioned to roll below flexible rod 3 and with flexible rod 3 and is connected, displacement measurement take turns 6 be positioned at flexible rod 3 with contact roller 7 above and roll with flexible rod 3 and be connected.One group of pressure sensor is uniformly distributed with along the circumference in the race of load test wheel 5.The outer rim of displacement measurement wheel 6 as shown in Figure 3, is uniformly distributed with one group of magnet along the circumference to 8, one group of magnet to 8 polarity cross-distribution; Displacement measurement wheel side is provided with hall device 9.Displacement measurement wheel 6 is connected with mounting bracket 4 end face with contact roller 7, and the race minimum point of displacement measurement wheel 6 and contact roller 7 takes turns the race peak of 5 lower than load test.The axis being parallel of mounting bracket 4 end face and flexible rod 3.
