Embodiment
Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the present invention to be described.
Embodiment 1
Two parallel guide rails 11 and 12 have been shown in Fig. 1, brief description is done to the shape of guide rail 11 below: the xsect of guide rail 11 is convex shape, comprise one first medial surface 111 and one second medial surface 112, (medial surface refers to the face of side near guide rail 12) this first medial surface 111 is vertical with this second medial surface 112, the bearing of trend that the direction (namely the direction of arrow in figure or the arrow in figure is reverse) perpendicular to xsect is guide rail.Guide rail 12 is identical with the shape of guide rail 11, and bearing of trend is also identical, does not repeat them here.
A kind of survey instrument of the present embodiment, for measuring the distance between guide rail 11 and guide rail 12, see Fig. 2-4, this survey instrument comprises two backstays 21 and 22 and a connecting link 23.Backstay 21 and 22 is fixedly connected on the two ends of this connecting link 23 respectively, and backstay 21 is parallel with 22 and vertical with this connecting link 23 respectively.
Below backstay 21 is elaborated:
Backstay 21 is rectangular parallelepiped, and adopt square steel to process, this rectangular parallelepiped comprises first surface 211,1 second face 212 and one the 3rd face 213, and this first surface 211 is parallel with this second face 212.
This first surface 211 is vertical with this connecting link 23 and be fixedly connected with, and this connecting link 23 is also positioned on the center line of this first surface 211.
This second face 212 is installed with two the first rollers 24 and 25.First roller 24 and 25 is set to: for rolling on the first medial surface 111 of guide rail 11, and rotating direction is parallel with the bearing of trend of guide rail 11; Other first roller 24 and 25 is equal to the distance at the center in this second face 212, and when rolling on guide rail 11 first roller 24 and 25 rolling track on the same line.
Rotating direction time rolling with 25 with the first roller 24 in 3rd face 213 on guide rail 11 is parallel, 3rd face 213 is installed with two the second rollers 26 and 27, second roller 26 and 27 is set to: for rolling on the second medial surface 112 of guide rail 11, and rotating direction is parallel with the bearing of trend of guide rail 11; The distance at the center in other second roller the 26 and 27 to the 3rd face 213 is equal, and when rolling on guide rail 11 second roller 26 and 27 rolling track on the same line.Wherein, the flatness of the first roller 24 and 25 and the second roller 26 and 27 is ± 0.5mm.
Backstay 22 is identical with the shape size of backstay 21, is provided with two first rollers identical with the second roller with the first roller of backstay 21 and two the second rollers too, and roll on guide rail 12, concrete set-up mode repeats no more.
This connecting link 23 is an expansion link.This expansion link comprises head rod 231,1 second connecting link 232 and a fixed knob 233.This head rod 231 is sheathed on the outside of this second connecting link 232, and this second connecting link 232 can be extracted out from this head rod 231.See Fig. 5, this fixed knob 233 is a screw, and this head rod 231 is provided with a screw, and this screw is through screw, the relative position of this head rod 231 and this second connecting link 232 can be fixed by locking this fixed knob 233, and then the length of this connecting link 23 is fixed.Wherein, the linearity of this expansion link is ± 1mm.This second connecting link is also provided with scale, and the distance that this second connecting link 231 is extracted out from this head rod 232 is longer, and the reading that scale marks is larger.
When using this survey instrument, those second rollers of backstay 21 and 22 are placed on the second medial surface 112 of guide rail 11 and 12 respectively, adjust the length of this connecting link 23, make those first rollers on backstay 21 and 22 respectively with the first medial surface 111 close contact of guide rail 11 and 12.Because this connecting link 23 is vertical respectively with 22 with backstay 21, and second of backstay parallel with the first medial surface of guide rail, first roller has good flatness, so this connecting link 23 is vertical with the bearing of trend of guide rail, distance between guide rail 11 and 12 just equals the total length of this survey instrument on the direction being parallel to this connecting link 23, namely equals the length * 2 of length+backstay 21 on the direction being parallel to this connecting link 23 of length * 2+ this connecting link 23 of the first roller 24 on the direction being parallel to this connecting link 23.
Embodiment 2
The survey instrument of the present embodiment is substantially identical with the survey instrument of embodiment 1, and difference is, see Fig. 6, in the survey instrument of the present embodiment, each backstay is only provided with the first roller 24 and 25 but is not provided with the second roller.The vertical view of this survey instrument is identical with Fig. 2.
When using this survey instrument, 3rd face 213 of the backstay 21 and 22 of this survey instrument is placed on the second medial surface 112 of guide rail 11 and 12 respectively, adjust the length of this connecting link 23, make the first medial surface 111 close contact of the first roller 24 and 25 on backstay 21 and 22 and guide rail 11 and 12.Because this connecting link 23 is vertical respectively with 22 with backstay 21, and the 3rd of backstay the is that plane is so this connecting link 23 also can be vertical with the bearing of trend of guide rail, distance between guide rail 11 and 12 just equals the total length of this survey instrument on the direction being parallel to this connecting link 23, namely equals the length * 2 of length+backstay 21 on the direction being parallel to this connecting link 23 of length * 2+ this connecting link 23 of the first roller 24 on the direction being parallel to this connecting link 23.
Embodiment 3
The survey instrument of the present embodiment is substantially identical with the survey instrument of embodiment 1, and difference is, see Fig. 7-8, in the survey instrument of the present embodiment, each backstay is provided with two the second rollers 26 and 27 but is not provided with the first roller.In addition, this connecting link 23 is not expansion link, but the fixed bar 28 that a length is constant.
When using this survey instrument, distance between adjustment guide rail 11 and 12, to make the second roller 26 and 27 on the backstay 21 and 22 of this survey instrument be placed on the second medial surface 112 of guide rail 11 and 12 respectively, the second face 212 of backstay 21 and 22 and the first medial surface 111 close contact of guide rail 11 and 12.After adjustment, the distance between guide rail 11 and 12 equals the total length of this survey instrument on the direction being parallel to this connecting link 23, namely equals the length * 2 of length+backstay 21 on the direction being parallel to this fixed bar 28 of this fixed bar 28.
Survey instrument of the present invention is not merely applicable to guide rail as shown in Figure 1, and the guide rail of other shape also can be suitable for.Survey instrument of the present invention may be used for measuring the distance between dock container separation sectional guide rail frame upper rail, improve guide rail bracket segmentation installation accuracy, reduce correction expense and the man-hour of guide rail bracket, promote that dock container examination case has been established, difficulty and the error rate of accuracy checking can also be reduced simultaneously, promote the efficiency of accuracy checking.
Although the foregoing describe the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, protection scope of the present invention is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present invention and essence, can make various changes or modifications to these embodiments, but these change and amendment all falls into protection scope of the present invention.
