Description

Asphalt pavement efficient scraping equipment Technical Field The invention relates to the technical field of asphalt scraping, in particular to efficient asphalt pavement scraping equipment. Background In the maintenance and renovation operation of asphalt pavement, the scraping equipment is a core construction instrument, and the operation efficiency and suitability of the equipment directly influence the engineering progress and the pavement repair quality. At present, asphalt pavement scraping equipment on the market mostly adopts a fixed exciting force structure, and vibration is generated through a single eccentric block or an eccentric assembly with a fixed phase, so that a scraper knife is driven to finish scraping operation. The device has obvious limitation in practical application, and is difficult to flexibly adapt to asphalt pavement with different thicknesses. When the thicker asphalt layer is processed, the fixed exciting force is often insufficient, so that the scraping force is insufficient, the expected effect can be achieved only by repeated operation, the construction efficiency is reduced, the equipment energy consumption and the abrasion of core components are increased due to continuous low-load vibration, and the service life of the equipment is shortened. When the thin asphalt pavement is treated, the fixed large exciting force is easy to exceed the bearing range of the pavement base layer, so that the base layer structure is damaged, the subsequent pavement quality is affected, and the maintenance and rework cost is increased. Meanwhile, the existing scraping equipment with the exciting force adjustable in part is complex in adjusting structure, the driving part shell is required to be disassembled, the eccentric block position is manually adjusted or the eccentric assembly is replaced, the operation flow is complex, a large amount of downtime is consumed, and the construction continuity is seriously affected. And the transmission structure design of the equipment is unreasonable, the problems of belt slipping, power interruption and the like easily occur in the power transmission process, the equipment cannot adapt to the long-time continuous scraping operation requirement, and the construction efficiency is further restricted. In addition, part of adjustable equipment lacks reliable auto-lock location structure, adjusts the back and is impacted under high frequency vibration, and the eccentric block phase angle easily takes place to skew, leads to the exciting force unstable, influences the precision and the operation uniformity of cutting. Meanwhile, the whole structure of the equipment is not enough in coordination, vibration impact is directly transmitted to each part, rigid collision among the parts is aggravated, larger running noise is generated, ageing and damage of the parts are accelerated, and equipment maintenance frequency and use cost are increased. Aiming at the defects of the prior art, a need exists for asphalt pavement scraping equipment which can flexibly adjust exciting force, is convenient to operate, runs stably and adapts to multiple operation scenes so as to meet actual construction requirements. Therefore, we propose an efficient scraping device for asphalt pavement.
