Abstract

The invention discloses a limiting device and relates to the technical field of engineering mechanical equipment manufacture. The limiting device comprises uprights, a ceiling and a mounting seat, wherein two uprights are available; one ends of the two uprights both are articulated with the mounting seat and the other ends of the uprights both are articulated with the ceiling; a limiting block is arranged between the two uprights; and one end of the limiting block is fixedly connected with one of the uprights. The connection line of the articulated points of the mounting seat with the two uprights, the axes of the two uprights and the connection line of the articulated points of the ceiling with the two uprights form a parallelogram two-rocker mechanism. The length of the limiting block between the two uprights is equal to the value of the distance between the two rockers when the two-rocker mechanism is in an extreme position. The limiting device is capable of solving the problems of complicated structure, difficulty in demounting, inconvenience in operation and high manufacture cost of the ceiling limiting device for the paver.

Description

technical field [0001] The invention relates to the technical field of construction machinery equipment manufacturing, in particular to a lifting and limiting device for the roof of a paver. Background technique [0002] Paver is an important equipment for road paving construction. Because it is often exposed to sunlight during operation, in order to protect the operator and allow the operator to have a more comfortable operating environment, it is generally necessary to set up a ceiling on the paver to provide shelter. The role of the sun; during construction, the set ceiling is supported by the column fixed on the paver mounting base, and the ceiling is fixed at the highest point of the column; but when the paver needs to be transferred, because of its slow driving speed, it needs to It is transported on a flatbed truck, and the paver has a high ceiling. During transportation, it will be limited by the height of culverts, bridges or tree branches on both sides of the road....
