Base plate of four-crawler-belt sliding formwork paver

Abstract

The invention discloses a base plate of a four-crawler-belt sliding formwork paver. The base plate comprises a hollow front cross beam and a hollow rear cross beam which are arranged on the same horizontal plane in parallel side by side. The two ends of the front cross beam and the two ends of the rear cross beam are integrally fixed and arranged through longitudinal beams. Proceeding steering devices are connected to the two ends of the front cross beam and the rear cross beam respectively, a leveling head telescopic beam parallel to the longitudinal beams is arranged between the two longitudinal beams, penetrates the center position of the bottom of the front cross beam and the center position of the bottom of the rear cross beam and is perpendicular to the front cross beam and the rear cross beam, and a leveling head is arranged at the end, close to the front cross beam, of the leveling head telescopic beam. The base plate has the advantages that operation is stable, flexibility is high, accessories are fast and convenient to replace, the construction efficiency is high, the structure is simple, the production cost is reduced, the purchasing and using performance cost ratio is high, and construction cost is reduced due to the modularized combination mode.

Description

Technical field: [0001] The invention relates to a road engineering equipment, in particular to a chassis of a four-track slipform paver. Background technique: [0002] Slip-mode cement concrete paver (referred to as slip-form paver). It integrates concrete distribution, metering, vibrating, sliding-form extrusion, flat rubbing, and smoothing. It can automatically, high-quality, one-time Pour the concrete material on the roadbed. This kind of self-propelled slipform paver usually includes a power system, a walking drive system, a hydraulic execution system, an automatic control system, etc. The chassis of the slipform paver is supported on 3-4 crawler or tire assemblies. This traveling support The device unit can be lifted and adjusted separately so that the chassis of the paver always maintains a horizontal plane. This traveling support device unit can also make the crawler or tire rotate left and right, and it can turn stably and freely when the paver is traveling. The chassis...

AI Technical Summary

Problems solved by technology

This self-propelled sliding form paver usually includes a power system, a walking drive system, a hydraulic actuator system, an automatic control system, etc. The chassis of the sliding form paver is supported on 3-4 crawler belts or tire assemblies. The device unit can be adjusted individually to keep the chassis of the paver on a horizontal plane. This traveling support device unit can also rotate the crawler belt or tires left and right, so that the paver can turn stably and freely when the paver is moving. The paver chassis is equipped with different functions. Equipment units such as: milling device, material conveying device, replacement sliding form adjusting device, sliding form forming mold, vibrating rod or vibrating plate are integrated into one, and the known existing sliding form paver has three crawlers and four crawler self-propelled The four-track self-propelled slip-form paver has a vertically traveling bottom-mounted slip-form die type and a side-mounted slip-form die-type slip-form paver. The two structures are different and their working principles are the same. Both methods are Surrounding pavement paving and paving of road bump guardrails, curbstones, and drainage ditches, the directional function is very prominent, and the use function is single and the scope of use is very narrow. Second, the existing slip-form paver pavement slip-form mold is assembled on the slip-form The two sides of the lower end of the paver chassis are self-propelled on the inner side of the crawler. This method is very difficult to construct in narrow construction conditions, because the crawler belts on both sides of the lower mold of the slipform paver occupy a certain space, and it is difficult to be competent in construction in narrow conditions.
