The invention relates to a telescopic mechanism for a slipform paver main frame. The telescopic mechanism comprises a main frame body, and a left telescopic structure and a right telescopic structure which are arranged on the main frame body, wherein the left telescopic structure comprises a left telescopic rod and a left driver which drives the left telescopic rod to stretch out and draw back; the right end of the left telescopic rod is inserted into an insertion hole of the main frame body, and the right end face of the left telescopic rod is provided with an axial hole leftwards; the right telescopic structure comprises a right telescopic rod and a right driver which drives the right telescopic rod to stretch out and draw back; the left end of the right telescopic rod is inserted into the insertion hole of the main frame body; the outer diameter of the right telescopic rod is smaller than the diameter of the axial hole of the left telescopic rod; the axis of the right telescopic rod and the axis of the left telescopic rod are on a same line; and the weight of the right telescopic rod and the weight of the left telescopic rod are equal to each other. The overall balance of a paver can be guaranteed, the weight of the paver is conveniently and uniformly distributed by a traveling system, and the most effective matching between the weight of the paver and the traveling system is realized.
Description
technical field [0001] The invention belongs to the technical field of paver equipment, and in particular relates to a telescopic mechanism for a main frame of a sliding mode paver. Background technique [0002] In the work of slip-form paver, it is usually necessary to adjust the frame width of the slip-form paver according to the requirement of paving width. Foreign sliding mode paver products only have a one-way telescopic frame structure, and its telescopic structure can only be unilaterally telescopic to realize the adjustment of the width of the main frame; this kind of one-way telescopic structure is easy to cause The machine is dumped on one side, which is not conducive to the uniform distribution of the machine mass to the walking system, and it is difficult to achieve the most effective match between the machine mass and the driving force of the walk. Contents of the invention [0003] In view of the above technical problems, the present invention provides a tel...
