Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples.
The walking equalizer bar 0 shown in FIG. 1 for just requiring machining for three parallel axis holes, the axis hole for needing to process be respectively in Between axis hole 01, left side pivot holes 02, right side pivot holes 03.
A kind of crane walking equalizer bar axis hole processing method, comprising the following steps:
Step (1): as shown in Fig. 2, being placed on the ground walking equalizer bar 0 using tooling square stool 2, with equalizer bar of walking Adjustment walking equalizer bar 0 is horizontal on the basis of horizontal stringcourse 1, and the equalizer bar 0 that will walk after adjustment is fixed;
Step (2): as shown in figure 3, with drawing intermediate shaft hole center line on the ground line-transect 31, left side pivot holes center line Line-transect 32, right side pivot holes center line ground line-transect 33 and transverse structure center line ground line-transect 34;
Wherein line-transect refers to the projection line of each center line on the ground.
The transverse direction of walking equalizer bar 0, vertical structure center line are determining after finishing, and intermediate shaft hole center line As soon as line-transect 31 and vertical structure center line line-transect be a line, therefore intermediate shaft hole center line line-transect 31 can draw;And it is left Side axle centerline hole line-transect 32, right side pivot holes center line line-transect 33 with intermediate shaft hole center line line-transect 31 is parallel, then At a distance from each with intermediate shaft hole center line line-transect 31, left side pivot holes center line can be drawn line-transect 32, right Side axle centerline hole ground line-transect 33.
Wherein, walking 0 two sides of equalizer bar intermediate shaft hole center line one piece of reflector is respectively fixedly installed on line-transect 31, The cross searching of two pieces of reflectors is with being respectively positioned on intermediate shaft hole center line on line-transect 31;The distance between two pieces of reflectors are greater than 20m。
Wherein, in the step (2), with drawing intermediate shaft hole center line line-transect 31, transverse structure center line ground line-transect 34 Afterwards detect intermediate shaft hole center line line-transect 31, transverse structure center line line-transect 34 verticality, the method for detecting verticality It is as follows, as shown in figure 3,
(2-1) intersection point of line-transect 34 and is denoted as to line-transect 31, transverse structure center line with determining intermediate shaft hole center line Heart intersection point 35;
(2-2) in intermediate shaft hole center line finds the equidistant two o'clock of distance center intersection point 35 on line-transect 31, remembers respectively For the first monitoring point 36, the second monitoring point 37;
(2-3) in transverse structure center line arbitrarily chooses a little on line-transect 34 and is denoted as third monitoring point 38;
(2-4) the measurement linear distance of third monitoring point 38 away from the first monitoring point 36 is simultaneously denoted as first distance, measures third Linear distance of the monitoring point 38 away from the second monitoring point 37 is simultaneously denoted as second distance;
(2-5) when the absolute value of first distance and second distance difference is less than 0.5mm, end step (2);
(2-6) re-starts step (2) when the absolute value of first distance and second distance difference is more than or equal to 0.5mm.
Step (3): the intermediate shaft hole central point on the both sides of the face of intermediate shaft hole 01 is determined using theodolite;According to determination Intermediate shaft hole central point determine the both ends of left side pivot holes central point and right side pivot holes 03 in the both ends of the surface of left side pivot holes 02 Right side pivot holes central point on face;And each center paste reflector, the cross searching position of reflector and this in Heart point is overlapped;
Wherein, in the step (3), the method for determining intermediate shaft hole central point is as follows, as shown in Figure 4:
Theodolite 5 is placed as the side of walking equalizer bar 0 by (3-1), and 5 bottom optical plummet of theodolite is made to emit one Laser point makes it with falling in intermediate shaft hole center line on line-transect 31;
The step be the laser that emits of theodolite 5 can premise that with intermediate shaft hole center line line-transect is overlapped, theodolite 5 is sharp Photo-emission source characteristic is can be in 360 ° of horizontal plane rotations or 360 ° of vertical plane rotations, only guaranteed rotation center (i.e. bottom Optical plummet) right above center line, the laser rays that could adjust camera lens transmitting is overlapped with center line.
(3-2) adjusts 5 camera lens of theodolite and emits first laser rays, and the endpoint of first laser rays is fallen in intermediate shaft hole Heart line on line-transect 31;It adjusts 5 camera lens of theodolite and emits Article 2 laser rays, the endpoint of Article 2 laser rays falls in intermediate shaft hole Center line on line-transect 31;
Bottom optical plummet emits a laser point in fact, makes it with falling in intermediate shaft hole center line on line-transect 31, so It adjusts first laser line endpoints with falling in intermediate shaft hole center line line-transect 31 again afterwards, that is, can guarantee that the laser rays of transmitting can be completely With sweeping to intermediate shaft hole center line on line-transect 31, transmitting Article 2 laser rays is to eliminate error, and whether detection laser beam is adjusted It is whole in place.
The camera lens that (3-3) adjusts theodolite 5 emits Article 3 laser rays, and the endpoint of Article 3 laser rays falls in walking level On the end face of beam 0 and it is denoted as at first point;
