In-site heating regeneration maintenance vehicle for asphalt pavements

Abstract

The invention discloses an in-site heating regeneration maintenance vehicle for asphalt pavements, comprising an automatic running type vehicle body, an asphalt pavement heating device for heating an asphalt pavement to melting state, a pavement planing-milling device for spiking up the molten asphalt pavement, an asphalt mixing device for mixing asphalt and additives to repair a pavement, an asphalt spreading device for spreading the mixed new asphalt material on the spiked pavement and a pavement compacting device for leveling and compacting the spread pavement, wherein the asphalt pavement heating device, the pavement planing-milling device, the asphalt mixing device, the asphalt spreading device and the pavement compacting device are sequentially arranged on the automatic running type vehicle body from front to back. The in-site heating regeneration maintenance vehicle for asphalt pavements can continuously complete the multiple operations of heating, spiking up, re-spreading, leveling and compaction, hydraulic transmission is adopted for a transmission device of the entire vehicle, the space can be reasonably utilized, the structure is simplified, the entire reliability of the device is beneficially guaranteed, and the field use cost is saved.

Description

technical field [0001] The invention relates to an automatic mechanical device, in particular to a vehicle integrating asphalt pavement plowing, paving and compacting. Background technique [0002] Asphalt pavement in-situ heating regenerative maintenance vehicles are widely studied and applied as the main key equipment in asphalt pavement maintenance equipment, mainly to prolong the service life of the road, ensure smooth traffic, reduce and avoid losses to the country and road users , Eliminate defects in time, repair damage, and keep the asphalt pavement in good condition. [0003] In the prior art, the principle commonly used in the hot-in-place regeneration and maintenance of asphalt pavement is to first heat the damaged pavement with a regeneration heater, plan and mill the heated and softened pavement with an asphalt pavement planer, and then use an asphalt mixing device to After the asphalt and additives are mixed evenly, they enter the hopper of the paver through t...
