The guide device 3 includes an upper guide frame 31, a lower guide frame 32, a guide wheel 33, and a flange 34. The flanges 34 on the upper and lower guide frames are bolted to the flange 28 of the jacking device 2.
In the preferred embodiment, the flange 34 and the flange 28 are connected by different spaced bolt holes, and the gap between the guide wheel 33 and the abutment can be adjusted by selecting different bolt hole connections to accommodate different size differences of the abutment.
In a preferred embodiment, the guide wheel 33 is made of nylon or polyurethane, so as to reduce vibration noise during the lifting process.
The climbing procedure corresponding to the above embodiment is as follows:
step 1, the whole automatic lifting platform is installed on a pier, and the rubber plate 15 is tightly attached to the surface of the pier stud 5 by the clamping force generated by the clamping oil cylinder 13 so as to generate enough friction force.
And 2, starting climbing, loosening the upper clamping device 11, and pushing the upper cross beam 21, the upper clamping device 11 and the construction platform 4 to move upwards by the jacking oil cylinder 23. When the stroke of the jacking oil cylinder 23 is reached, the upper clamping device 11 clamps, the lower clamping device 12 looses, the jacking oil cylinder 23 retracts, and the lower clamping device 12 and the lower cross beam 22 are driven to move upwards together. When the jacking cylinder 23 retracts to the right position, the lower clamping device 12 clamps, the upper clamping device 11 opens, and the second climbing cycle is repeated.
And 3, after the expected position is reached, simultaneously clamping the upper clamping device and the lower clamping device.
The technical features of the above-mentioned embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above-mentioned embodiments are not described, however, as long as there is no contradiction between the combinations of the technical features, or several variations and improvements can be made without departing from the concept of the present invention, they should be considered as being within the scope of the description.
