No. 69,395 Claims priority, application Great Britain, Sept. 16, 1969, 45,615/69 Int. Cl. E01c 19/48 US. Cl.
- a concrete paving machine comprises a main frame carrying a transversely-disposed conforming plate which, as the machine advances, levels plastic concrete delivered ahead of the machine, sub-frames mounted on endless tracks and upon which the main frame is supported with vertical adjustment and, between the main frame and each sub-frame a system of parallel linkage operable to constrain the sub-frame to move in a vertical plane relative to the main frame.
- This invention relates to concrete paving machines as used in the construction of roads, paths, runways and similar surfaces.
- the common form of paving machine at present in use comprises a main frame structure upon which is secured a conforming plate operable as the machine advances to level plastic concrete delivered onto the road or like subbase ahead of said plate.
- the main frame structure is usually supported on endless tracks and is vertically adjustable by means of jacks upon subframes carrying the endless tracks and their driving gear in order to vary the effective height of the conforming plate and thereby the depth of the laid concrete slab.
- Such machines will be referred to hereafter as machines of the kind mentioned.”
- the machine is steered to follow a pre-set course with the aid of a probe carried on the machine and co-operating with pre-placed guide or control wires alongside the surface to be paved, but difficultly is often experienced in accurately following a desired course, the main reason for which has been the tendency of the tracks to move inward or outward relative to the machine frame, particularly on curves, and the resulting change of spacing can be significant to the extent that the horizontal alignment of the laid concrete slab suffers.
- the present invention provides an improved construction of machine which obviates this defect, at least to a very substantial extent, so permitting the machine to follow more accurately a pre-set or pre-determined course.
- a restraining mechanism comprising a pair of vertically-spaced laterally-disposed arms or links operable in the manner of a parallel linkage to constrain the sub-frame to move in a vertical plane relative to the main frame structure.
- FIG. 1 is a fragmentary plan view of the improved paving machine
- FIG. 2 is a side view of FIG. 1.
- the main frame structure comprises two transversely-extending longitudinally-spaced tubular frame members 1 secured at their ends to vertical bracket structures 2 and at the front side of which is located a conforming plate 3, said plate in this instance being suspended at its ends on links 4 carried by the brackets 2 such that the conforming plate can swing transversely of the machine in the manner disclosed in the specification of US. Letters Patent No. 3,602,112 issued Aug.
- each set comprising two vertically-spaced swinging arms or links 10 which extend substantially laterally of the machine but converge slightly from their outer ends towards their inner ends.
- the arms are pivotally attached at their outer ends to the main frame structure and at their inner ends to two corners of a linking member in the form of a triangular-shaped plate 11 which, at its apex or third corner, has a pivotal connection 12 with the related sub-frame 6, the arrangement being such that any rising or falling movement of the sub-frame from its medial position and with corresponding tilting of the plate 11 rocks the arms 10 about their pivots in a manner such that the plate also moves outwardly to a degree sufficient to cause the apex thereof to move in a truly vertical path.
- the outer ends of the swinging arms 10 are pivoted on brackets 13 clamped or welded to the upper and lower sides of the tubular frame members 1.
- two sets of restraining links are provided to each sub-frame, the two sets being longitudinally spaced on the machine and the pivots for the outer ends of their swinging arms consisting of longitudinally-extending spindles 14 common to the arms of both sets and to which the arms are secured whereby the two sets of linkage are caused to move in unison and so ensure a parallel vertical movement of the sub-frame.
- a concrete paving machine comprising a main frame structure, sub-frames at opposite sides of the main frame structure associated with ground engaging means, means whereby said sub-frames and said main frame structure are relatively vertically movable, and restraining mechanisms between the main frame structure and each subframe each comprising a pair of vertically spaced laterally extending arms pivoted to the main frame structure, a linking member to which said arms are pivotally connected at spaced locations, and means pivotally connecting said linking member to the adjacent sub-frame, each said pair of arms being pivotally mounted at one end on the main frame structure and converging laterally inwardly towards their other ends where they have pivotal connection at spaced points with said linking member which at a third laterally outwardly disposed point has pivotal connection with the sub-frame, said pivotal connections being so related that said mechanisms act to constrain each subframe to move only substantially vertically relative to the main frame structure.
