Description
Technical Field
The invention relates to the technical field of pavers, in particular to a telescopic screed plate and a paver.
Background
Screed plates are very important working devices on paving machines for compacting, smoothing and shaping road surfaces, often having an screed plate, a base plate, a vibrating mechanism, etc. Depending on the width expansion, screed plates can be generally divided into hydraulically telescopic screed plates and mechanically built screed plates. Different working widths are realized by assembling lengthened sections with different widths through fasteners through the mechanical assembling screed plate, and the working width can be conveniently changed by enabling the telescopic section screed plate to be transversely (namely perpendicular to the advancing direction of the paver) telescopic relative to the basic section screed plate through the hydraulic telescopic screed plate.
The most common retractable screed at present has a width of about twice the width of the base when fully extended, and the screed includes a base section screed and left and right retractable section screeds which are disposed on the front side or the rear side of the base section screed at the same side and can be laterally retracted relative to the base section screed. The patent publication CN1198017C discloses a typical embodiment, which comprises a three-point supporting telescopic guide mechanism including a multi-stage telescopic tube, a guide circular shaft and a linear guide rail; further embodiments having telescoping guide mechanisms comprising multiple telescoping tubes or multiple guiding circular shafts or combinations thereof are known in the industry.
In addition, there is a screed which is approximately three times as wide as the base width when fully extended, but which has a non-negligible difference from three times the base width. The screed comprises a basic section screed and a left telescopic section screed and a right telescopic section screed which are arranged behind the basic section screed and are staggered in the front-rear direction, wherein the left telescopic section screed and the right telescopic section screed can transversely extend and retract relative to the basic section screed, and a typical embodiment is disclosed in a patent with the publication number of CN 1196834C.
It is well known in the industry that if the width of the screed to be paved exceeds the width of the screed when the screed is fully extended, the screed of the extension section needs to be manually assembled at the outer side of the screed of the extension section. However, disassembling and assembling the extended ironing board is time consuming and labor consuming, and causes additional burden in transportation.
