Detailed Description
The invention will be further described with reference to the following specific embodiments and the accompanying drawings.
As shown in the figure: the upright post positioning device comprises a fixed frame 3, a fixed shaft 1 and a telescopic hydraulic cylinder 7. The telescopic hydraulic cylinder 7 comprises a cylinder body and a telescopic rod, the cylinder body is fixedly arranged at one end of the fixing frame 3, and the telescopic rod extends into a sleeve of the fixing frame 3. The inner end of the fixed shaft 1 is inserted into the sleeve of the fixed frame 3 and is connected with a telescopic rod of a telescopic hydraulic cylinder 7. The fixing frame is effectively connected with the telescopic hydraulic cylinder 7 through the bolt, the whole stand column positioning device b is safely and reliably fixed on the lifting outer stand column a, the sleeve of the fixing frame 3 is provided with a through hole, the inner end of the fixing shaft 1 is provided with a through hole, a pin shaft 5 is arranged in the through hole, two ends of the pin shaft 5 extend out of the through hole, the pin shaft is well assembled with the fixing shaft and the telescopic hydraulic cylinder together, and meanwhile, the effect of a limiting detection source is also achieved. The fixed shaft 1 can stretch out and draw back in the range of the long waist hole under the action of the telescopic hydraulic cylinder 7, the fixed shaft retracts (figure 3), and the lifting of the inner upright post c is not affected; the fixed shaft extends out (figures 1 and 2) and reaches the fixed hole of the inner upright post c, and the inner upright post cannot lift.
Specifically, a groove is formed in the end part of the inner end of the fixed shaft 1, and the through hole is perpendicular to the groove; the telescopic rod end of the telescopic hydraulic cylinder 7 is provided with a support lug, the support lug is provided with a round hole and extends into the groove, and the pin shaft 5 penetrates through the through hole and the round hole to be connected with the fixed shaft 1 and the telescopic hydraulic cylinder 7 and is fixed by a check ring for a shaft.
Be equipped with sliding sleeve 2 in the sleeve of mount 3, fixed axle 1 and sliding sleeve 2 clearance sliding fit, the material of sliding sleeve is zinc-based alloy, has the lubrication action for the flexible action of fixed axle is more smooth and easy. Both ends at mount 3 all are equipped with the flange board, and the cylinder body of flexible pneumatic cylinder 7 is for taking flange mounting panel cylinder body, and the cylinder body is more stable with mount and mount 3 and outer stand a installation.
