H-shaped four-crawler-belt slipform paver

Abstract

A disclosed H-shaped four-crawler-belt slipform paver comprises an H-shaped telescopic chassis and crawler-type elevating turning apparatuses; the H-shaped telescopic chassis comprises two hollow longitudinal main beams, two transverse main beams and four hollow telescopic beams; the two transverse main beams are fixedly disposed between the top ends of the two longitudinal main beams; each of two ends of each longitudinal main beam is flexibly connected with the telescopic beam in an insertion manner; each telescopic beam is inside provided with a telescopic-beam oil cylinder; the top end of a piston rod of the telescopic-beam oil cylinder is connected with the telescopic beam, and the cylinder body of the telescopic-beam oil cylinder is fixedly connected with the longitudinal main beam; and the outer end of each telescopic beam is provided with the crawler-type elevating turning apparatus. The H-shaped four-crawler-belt slipform paver has the advantages that the four telescopic beams can have individual telescopic adjustment or have optionally-combined telescopic adjustment, so that the steady of the chassis and the paving flatness are guaranteed, the telescopic resistance of the telescopic beams is small, the adjustment manners are flexible and various, the application scope is wide, and the chassis can be adjusted into optional inclined angle according to different construction cases.

Description

Technical field: [0001] The invention relates to road engineering equipment, in particular to an H-type four-crawler sliding form paver. Background technique: [0002] Four-track sliding mode cement concrete paver (sliding form paver for short), which integrates concrete distribution, metering, vibration, sliding form extrusion, flat rubbing, and smoothing, can be automatic, high-quality, and once The concrete material is poured and formed on the subgrade; the width of the chassis and the height from the ground are usually adjusted at any time according to the construction requirements; the existing slip mode paver can only extend or retract the two crawlers on one side at the same time To realize the adjustment of the width of the main frame, the overall center of gravity of the sliding form paver will change accordingly after adjustment, and the sliding form mold fixed on the chassis should also be adjusted to re-balance the center of gravity of the chassis; otherwise, dur...
