Description

一种振动压路机的作业方法
技术领域
本发明涉及振动压路机, 具体地, 涉及一种振动压路机的作业方法。 背景技术
当前, 振动压路机广泛地应用在道路施工中。 其主要依靠其自身的重 力和振动压实各种建筑和筑路材料。 在公路建设中, 振动压路机最适宜压 实各种非粘性土壤、 碎石、 碎石混合料以及各种沥青混凝土, 因而被广泛 应用。 其中, 振动压路机主要可分为单钢轮振动压路机和双钢轮振动压路 机。 然而, 在实际施工中, 经常出现振动压路机在某个区域出现振动轮沉 陷的问题, 而一旦出现沉陷问题, 将对路面造成很大影响, 需要对该区域 进行修复, 从而延长了施工成本和施工工期。 目前业界对该振动轮的沉陷 问题一直未有有效的解决方法, 因此, 需要一种振动压路机的作业方法, 能够避免振动压路机的振动轮沉陷。 发明内容
本发明的目的是提供一种振动压路机的作业方法, 该作业方法能够避 免振动压路机的振动轮沉陷。
为实现上述目的, 本发明提供一种振动压路机的作业方法, 其中, 在 所述振动压路机的振动轮的振动过程中, 当车速小于阈值时, 停止所述振 动轮的振动。
优选地, 所述阈值为 1.5-2.5km/h。
优选地, 所述作业方法包括实时检测车速, 将检测的车速的值与所述 阈值进行比较, 在所述车速的值小于或等于所述阈值时, 停止所述振动轮 的振动。 优选地, 所述振动轮由液压泵和液压马达驱动振动, 停止所述振动轮 的振动包括使所述液压泵停止工作。
优选地, 在所述振动压路机上安装控制器和速度检测装置, 所述控制 器内设置有所述阈值, 所述速度检测装置将检测到的车速的值传送给所述 控制器, 所述控制器将所述车速的值与所述阈值的比较, 以控制所述液压 泵的工作。
优选地, 所述振动压路机为单钢轮振动压路机或者双钢轮振动压路机。 通过上述技术方案, 由于本发明提供的作业方法, 能够根据振动压路 机的车速和阈值的比较结果停止振动轮的振动, 因此能够避免振动压路机 的振动轮的沉陷。
本发明的其他特征和优点将在随后的具体实施方式部分予以详细说 明。 附图说明
附图是用来提供对本发明的进一步理解, 并且构成说明书的一部分, 与下面的具体实施方式一起用于解释本发明, 但并不构成对本发明的限制。 在附图中:

以下结合附图对本发明的具体实施方式进行详细说明。应当理解的是, 此处所描述的具体实施方式仅用于说明和解释本发明, 并不用于限制本发 明。
根据研究发现, 振动压路机的振动轮沉陷主要是由于该振动轮 1 长时 间停留在某个区域内, 并且不断振动而造成的。 因此, 如图 1 所示, 本发 明提供一种振动压路机的作业方法, 在振动压路机的振动轮的振动过程中, 当车速小于或等于阈值时, 停止振动轮 1的振动。
在上述技术方案中, 由于振动压路机在作业时会根据当前的行驶速度 和阈值的比较结果判断是否继续振动, 当振动压路机的行驶速度小于阈值 时, 即该振动轮 1停留在某个区域内的时间过长, 则停止该振动轮 1 的振 动, 以避免由于长时间在该区域的振动而造成振动轮沉陷。
需要说明的是, 本发明所涉及的阈值需要根据不同的路面情况而不同。 在本发明中, 经过大量实验后, 优选地, 阈值为 1.5-2.5km/h。 此阈值的范 围能够应用于大部分路面情况, 如非粘性土壤、 碎石、 碎石混合料以及各 种沥青混凝土的路面。 另外, 本领域技术人员能够理解的是, 实际中的一 种路面对应 1.5-2.5km/h中一个阈值。 另外, 该阈值范围也并不是绝对值, 根据路面情况能够对该阈值的范围进行改变, 只要满足本发明的目的, 此 类改变也应落在本发明的保护范围内。
具体地, 在实际作业中, 本发明提供的作业方法包括实时检测车速, 并将检测的车速的值与阈值进行比较, 为了更加安全, 在车速的值小于或 等于阈值时, 停止振动轮 1 的振动。 即除了车速小于阈值的情况停止振动 轮 1的振动外, 当车速的值等于阈值时, 即停止振动轮 1的振动。
为了方便操作, 优选地, 振动轮 1 由液压泵 2和液压马达 3驱动, 停 止振动轮 1 的振动包括使该液压泵 2停止工作。 即为了方便操作, 需要为 振动轮 1的振动液压马达 3配备专门的振动液压泵 2。 当需要停止振动轮 1 的振动时, 直接关闭该振动液压泵 2, 继而使振动液压马达 3失去动力, 方 便地停止该振动轮 1的振动。
如图 1和如图 2所示, 为了实现本发明, 优选地, 在振动压路机上安 装控制器 4和速度检测装置 5,控制器 4内设置有所述阈值, 速度检测装置 5将检测到的车速的值传送给控制器 4, 控制器 4将该车速的值与所述阈值 的比较, 以控制液压泵 2的工作。
即, 当车速小于或等于该阈值时, 控制器 4控制所述液压泵 2停止工 作, 以停止振动轮 1的振动, 当车速大于该阈值时, 控制器 1维持所述液 压泵 2的工作, 并继续比较由速度检测装置 5传送来的车速和阈值。 其中, 本发明设计的速度检测装置 5和控制器 4均为本领域内常见的部件, 例如 控制器 4为 PLC控制器, 速度检测装置 5为速度传感器。 除了上述技术方 案外, 本领域技术人员可以使用其他技术方案实现本发明提供的振动压路 机的作业方法, 这种技术方案同样落在本发明的保护范围内。
