Problems solved by technology

[0004] In the past, RA resin asphalt adhesive layer was painted manually. For the construction of large-area, large-width, and full-width steel bridge deck pavement, manual painting has brought about high cost input, high labor intensity, and low efficiency. It is difficult to meet the construction and quality requirements due to uneven application of RA resin asphalt and waste, so it is necessary to develop a high-efficiency and uniform RA resin asphalt spreader to meet the requirements of RA resin on wide steel bridge decks.

Abstract

The invention discloses an RA resin asphalt spreader. The RA resin asphalt spreader comprises a walking vehicle, wherein a control cabinet, an engine, an air compressor, a resin asphalt stirring tank and a conveying pump are arranged on the upper surface of the walking vehicle in sequence from right to left; a lifter is arranged at the leftmost end of the walking vehicle; a row of nozzles is mounted on the lifter; an electric generator is electrically connected with the air compressor; pneumatic valves are arranged on the upper surfaces of the nozzles; the air compressor is connected with the pneumatic valves through pipelines; an output port of the resin asphalt stirring tank is connected with the conveying pump through a pipe; and a flow meter and a pressure sensor are arranged between the conveying pump and the nozzles. The spreader brushes RA resin asphalt with uniformity and high efficiency. The invention further discloses a spreader cleaning device convenient for cleaning the RA resin asphalt spreader.

Description

technical field [0001] The invention relates to the technical field of RA resin asphalt spreading, in particular to an RA resin asphalt spreading machine and a cleaning device thereof. Background technique [0002] Among the currently popular steel bridge deck pavement systems in China, the resin asphalt composite system (EBCL+RA05+SMA, ERS for short) where "E" (Epoxy bonding chips layer) is the English name for epoxy bonded gravel anti-skid layer Abbreviation, "R" (Resin Asphalt) is the abbreviation of resin asphalt concrete, "S" is the abbreviation of SMA pavement. The typical structure of ERS steel deck pavement is EBCL+RA05+SMA10. EBCL is used as the waterproof and anti-skid bonding layer, RA05 is used as the integrated pavement layer, and SMA10 is used as the surface functional layer, and the division of labor of each layer is clear. The ERS steel bridge deck pavement system is a domestic independent innovation technology, with reliable material supply and low overall...
