A system and equipment for automatically controlling the elevation of the forming surface of ultra-high performance concrete

Abstract

The invention discloses a system and equipment for automatically controlling the super-high performance concrete forming surface elevation. The equipment comprises a relative elevation control track,a connecting frame, an elevation adjusting device and a controller, wherein the relative elevation control track is arranged on the side of a leveling beam; the connecting frame synchronously moves with the leveling beam; the elevation adjusting device is used for adjusting the elevation of the leveling beam; the controller is used for receiving a signal and controlling the elevation adjusting device; a relative elevation sensor, a walking distance sensor and a guide wheel are mounted on the connecting frame; the guide wheel is connected with the relative elevation control track in a rolling fit manner; and the elevation adjusting device, the relative elevation sensor and the walking distance sensor are all electrically connected with the controller. The equipment disclosed by the invention has the benefits that the structure is simple, the use is convenient; and by additionally arranging a control system device on existing leveling equipment, the leveling beam can automatically adjustthe elevation according to the walking position in the construction process, so that the purpose of automatically and continuously adjusting transverse and longitudinal slopes and bridge deck elevation is achieved.

Description

technical field [0001] The invention relates to an ultra-high-performance concrete molding surface elevation control system, which belongs to the technical field of new construction equipment for civil engineering, and in particular to a system and device for automatically controlling the ultra-high-performance concrete molding surface elevation. Background technique [0002] Due to its high mechanical properties, ultra-high performance concrete has gradually been widely used as a bonding transition layer between the steel bridge deck and the bridge deck asphalt pavement. Ultra-high performance concrete has high strength and good expansibility, but it is usually relatively viscous and contains steel fibers. Therefore, manual paving methods are not suitable for bridge deck paving operations. Traditional pavement paving equipment needs to be It can be applied only after modification, and special equipment is usually used for paving. The special equipment generally includes eq...

AI Technical Summary

Problems solved by technology

There are more and more changes in the alignment of the bridge deck, which makes the transverse and longitudinal slopes of the road surface more and more variable. The level control method of the flat beam is difficult to meet the accuracy requirements of the level and slope, and the operation efficiency is also very low
