SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model aims at providing a fortune frame all-in-one machine auxiliary leg structure.
The utility model adopts the following technical scheme for accomplishing the above purpose:
an auxiliary supporting leg structure for a transportation and support integrated machine; an auxiliary supporting leg structure for assisting the cantilever through hole of the transporting and erecting integrated machine is arranged in front of the crane trolley in the middle of the main beam; the auxiliary supporting leg structure is provided with a cross beam connected with the main beam; the two beams are symmetrically arranged, and each beam is hinged with the corresponding upright post; the upright post is a structure which can rotate around a steel pin in the longitudinal direction of the frame transporting integrated machine; a supporting pad pier is arranged below the upright post; the supporting pad pier is contacted with the top surface of the erected box girder through a steel plate rubber plate embedded in the supporting pad pier; a jacking oil cylinder is arranged between the upright post and the supporting pad pier; the cylinder barrel of the jacking oil cylinder is fixedly connected with the upright post; when in use, a piston rod of the jacking oil cylinder is supported on the supporting pad pier in a jacking and contacting manner; a piston rod of the jacking oil cylinder is provided with trapezoidal threads, and the end of the piston rod is matched with a locking nut; the locking nut can rotate up and down on the piston rod; the locking nut is matched with a piston rod of the jacking oil cylinder to form a protection locking mechanism of the piston rod.
The support pad piers are arranged up and down, elastic pads are arranged between the two support pad piers, and the upper support pad pier and the lower support pad pier are fixedly connected into a whole through bolts and nuts.
The utility model provides a transport and put up auxiliary leg structure for all-in-one machine adopts above-mentioned technical scheme, sets up lock nut through the tip at the piston rod, realizes the protection to the piston rod to avoid because the hydro-cylinder became invalid, and cause the disaster situation that the complete machine toppled over. The piston rod of the oil cylinder is provided with trapezoidal threads, and the locking nut can rotate up and down on the threads. The bearing capacity of the screw thread is larger than the maximum supporting counter force of the auxiliary supporting leg under the working condition; the locking nut is in contact with the wall of the oil cylinder to mechanically lock the oil cylinder; when the oil cylinder is lifted, the locking nut can be rotated simultaneously, so that the locking nut is kept near the wall of the oil cylinder at any time; when the oil cylinder is contracted, the locking nut needs to be released in advance.
