Guide roller mechanism for pavement laying and withdrawing

Abstract

The invention discloses a guide roller mechanism for pavement paving and withdrawing. The guide roller mechanism comprises a roller support, a fixed support, a rotating shaft, a pin shaft, wheel shafts, a roller and a guide wheel, a connecting hole B in the end C of the roller support is in pin joint with connecting holes A in two side plates of the fixed support through the rotating shaft; the roller support can rotate around the axis of the rotating shaft, and when the positioning hole of the roller support is coaxial with the limiting hole A of the fixed support and is connected with the limiting hole A of the fixed support through a pin shaft, the roller support is located at an upward swinging position; when the positioning hole of the roller support and the limiting hole B of the fixed support are coaxial and are connected through the pin shaft, the roller support is located at a lower swinging position; the three wheel shafts are respectively fixed in connecting holes B in the end A, the end B and the end D of the roller support; each wheel shaft is provided with a roller and a guide wheel; the mechanism is simple in structure, reliable in work, convenient to maintain, economical in cost and capable of supporting and guiding the pavement unit plate, and the problem of deviation of the pavement unit plate is solved.

Description

technical field [0001] The invention belongs to the technical field of pavement paving, and in particular relates to a guide roller mechanism for pavement paving retraction. Background technique [0002] As our country pays more and more attention to the field of emergency transportation security, more and more emergency rescue equipment has been released. The hard pavement vehicle is a kind of temporary mobile pavement mainly used for quickly laying temporary movable pavements in areas with low load-carrying capacity such as beaches, muddy fields, etc., to ensure the passage of crawler-loaded and wheeled-loaded vehicles, to improve mobility, and to provide temporary supplies Lay temporary passages in facilities such as transfer stations, warehouses, stations, and various construction sites. However, due to the high flexibility of the joints of the pavement unit plates, the paving vehicle is prone to offset and skew when it is working. Therefore, it is particularly importan...
