发明名称 TELESCOPIC SCREED AND PAVING MACHINE THEREOF
摘要 A telescopic screed is provided which includes main section and telescopic section screeds, the main section screed includes a screed frame and a base plate; the telescopic section screeds are arranged on the left side and/or the right side of the main section screed and include a cross slope framework, a cross slope driver, at least two multistage sliding pipes, a telescopic frame, a telescopic driver, a telescopic section frame, a telescopic section base plate and an elevation difference driver; the cross slope framework is pivotally connected with the main section screed to adjust the cross slope; the multistage sliding pipes are used for transversely guiding the telescopic frames to achieve the telescopic ability of the telescopic section screeds; the telescopic section frame is connected with the corresponding telescopic frame to move up and down to adjust the relative height between the telescopic section frame and the telescopic frame.

主权项 1. A telescopic screed, comprising a main section screed and telescopic section screeds, wherein the main section screed comprises a main section screed frame and a main section base plate; the telescopic section screeds are arranged on a left side and/or a right side of the main section screed, the telescopic section screeds further comprising: a cross slope framework which is pivotally connected with the main section screed so that the cross slope framework can pivot relative to the main section screed in a plane which forms an angle of 80°-90° with a travelling direction; a cross slope driver, which is connected with the main section screed and the cross slope framework and which is used for adjusting a cross slope of the cross slope framework relative to the main section screed; at least two multistage sliding pipes, each comprising an outer pipe, at least one intermediate pipe and an inner pipe which are sequentially telescoped and can slide relatively along an axial direction, wherein the outer pipe is transversely fixed to the cross slope framework; a telescopic frame moving transversely relative to the cross slope framework, with the inner side thereof slidably connected to the outer pipe of the multistage sliding pipe and an outer side thereof connected to the inner pipe of the multistage sliding pipe; a telescopic driver for driving the telescopic frame so that the telescopic frame moves transversely with respect to the cross slope framework; a telescopic section frame connected with a lower portion of the telescopic frame in a manner of being able to move up and down; an elevation difference driver connected between the telescopic frame and the telescopic section frame to adjust a height of the telescopic section frame relative to the telescopic frame; and a telescopic section base plate connected to a bottom of the telescopic section frame.
