Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with specific embodiment, and reference
Attached drawing, the present invention is described in further detail.
A kind of hydraulic support linearity testing apparatus combined with Figure 1 and Figure 2, the cabinet 1 including cube structure, the case
It is offered in 1 front surface 2 of body using 2 center of front surface as the through-hole 21 in the center of circle, 3 center of rear surface of cabinet 1 is fixed with one and passes through
The bracing wire rope 4 of through-hole 21, the length that the bracing wire rope 4 stretches out cabinet 1 can change, and divide on one group of adjacent side of cabinet 1
It is not fixed with light source 5, projection line of the bracing wire rope 4 under light source 5 can be identified by being respectively arranged on another group of adjacent side
Photosensitive element 6.The angle for deviateing central axes by the projection of identification bracing wire rope 4 on two side faces, that is, can determine that bracing wire rope 4 is inclined
Angle from rear surface normal direction can determine two planes with the presence or absence of relative displacement by specific fixed form.
The light source 5 selects the source of parallel light perpendicular to side where it, can also be converted into point light source by lens
Source of parallel light, so that it is guaranteed that bracing wire rope 4 is projected as orthographic projection on side.
The bracing wire rope 4 uses tensile elastic string, in preferred embodiment, 1 rear surface 3 of cabinet fix one it is automatic
Ropewinder (not shown) is stretched out out of automatic ropewinder when bracing wire rope 4 receives pulling force, and after pulling force disappears, bracing wire rope 4 is furled back certainly
In dynamic ropewinder.
Ambient generates interference to the projection of bracing wire rope 4 in order to prevent, is additionally provided with before front surface 2 lighttight soft
Property corrugated paper (not shown), bracing wire rope 4 can pass through corrugated paper, bracing wire rope 4 relative to rear surface 3 normal direction deflection when, ripple
Paper will not prevent the movement of bracing wire rope 4.
With reference to Fig. 3, the rear surface 3 is removably fixedly connected with cabinet 1, and the four corners of the rear surface 3 are set respectively
It is equipped with the orientation angle 31 vertical with rear surface 3, each orientation angle 31 is respectively provided with determines with what the two neighboring side of cabinet 1 was close to
Position plate 32, preferred embodiment summarize the inside that positioning plate 32 is set to cabinet 1, and two positioning plates 32 of each orientation angle 31
End interconnects into a single integrated structure.For the ease of the entire detection device of fixation, the rear surface 3 where it plane to extension
It stretches and is provided with multiple lugs 34 with fixation hole 33, fixed in the plane by the device that will test that lug 34 can be convenient.
The present embodiment additionally provides the method for detecting two relatively straight dimensions of plane using above-mentioned detection device, with reference to Fig. 4,
It will test the O point that device is fixed on datum plane A, the free end of bracing wire rope 4 be fixed on the P point on plane B to be measured, and
When datum plane A is overlapped with plane B to be measured along normal direction, OP defines plane B phase to be measured perpendicular to datum plane A and plane B to be measured
For the straightness δ of datum plane A are as follows:
Wherein, α is the angle of bracing wire rope Yu datum plane normal direction, and δ shows that plane to be measured is flat relative to benchmark closer to 1
The departure degree in face is bigger.
Angle [alpha] meets following relationship:
I.e.
Wherein, θ andIt is projection of the bracing wire rope on body side and the straight line in the plane perpendicular to rear surface respectively
Angle.Angle, θ andIt is directly measured relative to central axes after can identifying the projection of bracing wire rope 4 by photosensitive element 6
Angle.
Fixed test device and bracing wire rope 4 will be distinguished on the side of adjacent hydraulic support top beam according to the above method
Free end can easily detect the straightness between two adjacent hydraulic supports, so that it is determined that two adjacent hydraulic supports
Between whether meet straightness requirement, and when needing to reduce the straightness between two hydraulic supports, by adjusting allowing
Angle, θ andLevel off to 0.
It should be noted that only can determine that there is deflection between two planes by the above method, but it can not determine two
The angle of plane, and can not also measure when fixing the fixed point of plane opposing elastic force rope of stretch cord and deflecting in the presence of inclined
Turn, but for the usage scenario of hydraulic support, this problem can be ignored, therefore method provided in this embodiment can
Effective detection judgement is carried out to the straightness of hydraulic support；When there is other to require, it may be considered that distinguish on two planar
It is arranged in detection device provided in this embodiment or wherein a plane and multiple detection devices is set.
