Embodiment
As shown in Figure 1-Figure 3, a kind of crane for including system for automatically correcting, includes two tracks being parallel to each other
1 and the vehicle frame 2 that can be moved along the length direction of track 1, the both sides of vehicle frame 2 are provided with and can rolled on two tracks 1
The first roller 3 and the second roller 4, motor 5, the rotating speed of controlled motor 5 that the first roller 3 of driving is rotated are additionally provided with vehicle frame 2
Frequency converter 6, two ends connect the decelerator 7 of the roller 3 of motor 5 and first respectively, for measuring between the first roller 3 and track 1
Sideshake clearance measurement component, the SCM system 8 that data are handled, single-chip microcomputer system are surveyed to clearance measurement component
System 8 connects frequency converter 6.Clearance measurement component is monitored in real time by measuring the sideshake between the first roller 3 and track 1,
Changed by SCM system 8, the signal value that clearance measurement component is surveyed is control voltage, and the change of control voltage is in frequency conversion
Device 6 is converted into the change of frequency, so as to change the speed of service of motor 5, wherein clearance measurement component, which surveys gap, a standard
The setting value in gap, the actual gap detected, which is more than setting value, then gradually reduces the rotating speed of motor 5, it is on the contrary then gradually increase it is electric
The rotating speed of machine 5.Controlled respectively by two the first rollers 3 to the both sides of vehicle frame 2 so that the operation of the first roller of both sides 3
Speed tends to be equal so that vehicle frame 2 can be stablized to be run on path 1, and it is to be used to draw lift heavy thing to make in crane to ask it, is moved
During acutely rock and do not interfere with the stable operation of vehicle frame 2 on path 1 still, be not in " gnawing rail phenomenon ".
Wherein, clearance measurement component include be arranged on vehicle frame 2 can rotation rotary encoder 9, rotation can be driven
Turn encoder 9 rotation swing rod 10, be arranged on swing rod 10 dorsad the slider roller 11 of the end of rotary encoder 9, cause slide
The holddown spring 12 of the laminating track 1 of roller 11 side.The purpose of holddown spring 12 is in order that can under the normality of slider roller 11
Laminating track 1, so that the gap width of measurement is accurate.Measuring principle is as follows：When the relative orbit 1 of the first roller 3 is displaced sideways,
Because slider roller 11 is close to track 1, rotary encoder 9 can cause swing rod 10 around slider roller with the lateral movement of the first roller 3
11 rotate, and swing rod 10, which is rotated, drives axis of rotation on rotary encoder 9, so that after the relative orbit 1 of the first roller 3 is displaced sideways
So that the variable quantity relative to original interstice is converted into the rotation amount of the record of rotary encoder 9, pass through the letter based on rotation amount
Number carry out convert then relative to setting benchmark instructed, the forward and backward of controlled motor 5 and the rotating speed of motor 5, motor 5
Rotating have the first roller 3 relative to the sidesway direction of track 1 to determine, in order to eliminate minimum gap.Slide
Roller 11 is preferably metal material, and cylindrical in slider roller 11 is provided with wear plate.
It is wound with scroll spring 13 outside second roller 4, the end of dorsad the second roller 4 of scroll spring 13 is fixed on track 1
On.The effect of scroll spring 13 is to provide for the power of 2 one bufferings of vehicle frame so that vehicle frame 2 is after power is lost, by weight
The response retracted is relatively gentle, is not very big in the weight of weight, when the elasticity of scroll spring 13 is enough, it might even be possible to rise
To the temporary transient effect for hanging weight.
The both ends of the surface of first roller 3 are radially extended can block the flange of track 1 in both sides.Second roller
4 both ends of the surface are radially extended can block the flange of track 1 in both sides.Flange is used to control the He of the first roller 3
Interval section between track 1, the spacing of two side flangings is greater than the width of track 1.Clearance measurement component in the present embodiment
Effect purpose be in order that track 1 is tried one's best and is maintained at the centre positions of two side flangings so that the gap uniformity of both sides, this
Frictional force between the first roller of sample 3 and track 1 is minimum.
