The invention discloses a crawler belt tensioning system, a paver and a method, and belongs to the technical field of engineering machinery. The crawler belt tensioning system comprises a tensioning oil cylinder, a guide wheel frame, a guide wheel and a fixedly arranged supporting beam; a spring is sleeved on an oil cylinder of the tensioning oil cylinder, one end of the spring is propped against the tensioning oil cylinder, and the other end of the spring is propped against the guide wheel frame; the tensioning oil cylinder is connected with the hydraulic control system through a pipeline; the hydraulic control system controls the tensioning oil cylinder to stretch out and draw back, and the tensioning oil cylinder drives the guide wheel to move to adjust and tension the crawler belt. According to the system, the tension change of the crawler belt caused by the position change of the guide wheel under the external load under different working conditions is compensated, the abnormal working phenomenon of over-looseness or over-tightness of the crawler belt is prevented, the vector adjustment of the tensioning of the crawler belt can be realized, and the working performance and the application capability of the paver are further improved.

    本发明公开了一种履带张紧系统、摊铺机及方法,属于工程机械技术领域,包括张紧油缸、导轮架、导向轮和固定设置的支撑梁;所述张紧油缸的油缸上套设有弹簧,所述弹簧的一端抵设于所述张紧油缸上,另一端抵设于所述导轮架;所述张紧油缸与液压控制系统管路连接;所述液压控制系统控制张紧油缸伸缩,所述张紧油缸驱动所述导向轮移动对履带调节张紧;补偿不同工况下因导向轮受到外载荷发生位置变动引起的履带松紧变化,防止履带出现过松或过紧的非正常工作现象,本系统可以实现履带张紧的矢量调节,进一步提高了摊铺机的工作性能和适用能力。
