Definitions
- the present invention relates generally to mobile public works machines on a site.
- the invention relates to a machine of the type comprising at least three sets of movable contact with the ground, each contact set being able to consist of a wheel or a set of wheels, or of a track for example.
- An advantageous configuration for making such adjustments consists in providing three contact sets between the machine and the ground, two contact sets being aligned along the longitudinal axis of the machine corresponding to its direction of advance, for example being made integral with the 'a longitudinal frame, while the third contact assembly is spaced from this longitudinal axis (for example by being made integral with a transverse frame fixed to the longitudinal frame).
- This configuration makes it possible to adjust the roll angle in a particularly simple manner, by simply adjusting the height of the machine platform relative to the contact assembly which is spaced from the longitudinal axis of the machine (for example by a system of jacks placed between the platform and said contact assembly). And it is also advantageous to further provide that the contact assembly spaced from the longitudinal axis of the machine is located opposite one of the two other contact assemblies, in the transverse direction of the machine. Thus, it is also possible to carry out a simple adjustment of the pitch angle of the machine, by adjusting only the height corresponding to the contact assembly which is located on the longitudinal axis of the machine, and which is not in look of the contact assembly located outside this axis.
- Machines which make it possible to carry out operations such as the continuous casting of concrete profiles.
- This type of machine is supported by three crawler trains which constitute the three sets of contact with the ground, the three crawler trains forming a
- the tool is fixed on one side of the main chassis and, for many applications, one of the two sides of the chassis is clearly better suited to the conduct of operations (for questions of mass distribution in the case of tools heavy, accessibility of the tool, visibility offered to the operator of the machine ).
- the machines if they have a preferred side, can sometimes be adapted to receive the on-board tool on the side not corresponding to the preferred side.
- the main object of the present invention is to eliminate this drawback.
- the invention proposes a public works machine comprising:
- the three mobile contact assemblies being arranged so as to form an “L” when the machine is in operation, the first two mobile contact assemblies being integral with a longitudinal chassis assembly of the machine while the third movable contact assembly is integral with a transverse element which is connected to the longitudinal chassis assembly and which extends substantially transversely to said longitudinal chassis assembly, characterized in that 'There are provided means of articulation between the longitudinal chassis assembly and the transverse element, so as to allow relative movement between the transverse element and the longitudinal chassis assembly so that the transverse element passes from side to side of the longitudinal chassis assembly.
- Preferred but non-limiting aspects of the machine according to the invention are the following: . during said relative movement the transverse element is fixed on the ground, the ensble of longitudinal chassis being movable relative to the ground. . during said relative movement, the longitudinal chassis assembly is fixed on the ground, the transverse element being movable relative to the ground,. the articulation means allow movement according to a single degree of freedom between the transverse element and the longitudinal chassis assembly,. the articulation means allow pivoting about a vertical axis,. the number of mobile contact assemblies is limited to three,. the moving contact assemblies are crawler trains. . means are provided for stabilizing the part of the machine remaining fixed relative to the ground during the relative movement between the transverse element and the longitudinal chassis assembly,.
- the invention also relates to the use of a machine according to one of the above aspects, to constitute a structure joined in a direction substantially perpendicular to an existing structure.
- FIG. 1 is a side elevation view of a machine according to the invention,.
- FIG. 2 is a front elevation view of the same machine,.
- FIG. 3 is a top view of the same machine,
- FIGS. 4a to 4c are three top views illustrating three configurations of the machine according to the invention.
- FIGS. 5a to 5c are three schematic representations of the machine according to the invention in top view, illustrating the stages of the constitution of a structure 30 backed by an existing structure 20.
- FIG. 1 there is shown a machine generally designated by the reference 10, intended to produce concrete profiles such as slabs, curbs or walls, continuously in the field.
- the machine 10 is provided with crawler trains allowing it to be mobile in the field.
- FIG. 1 are thus represented a first track train 11 located at the front of the machine (on the left of the figure), and a second track train 12, aligned in the longitudinal direction of the machine behind the track train 11.
- the tracks 11 and 12 are both mounted on a longitudinal chassis 13.
- the crawler train 12 is fixedly mounted on the chassis 13 by means of a plate 120 fixed on the underside of the chassis 13, while the crawler train 11 is pivotally mounted around a vertical axis 110 on a plate 111, which is itself mounted on the front of the chassis 13 by means of an adjustable parallelogram 112 formed by two parallel articulated arms 1120 and 1121.
- a first rear end 11201 of the arm 1120 is mounted on the front of the longitudinal frame 13 pivoting about a horizontal transverse axis (perpendicular to the plane of Figure 1), so that the arm 1120 can move relative to the frame 13 only by a rotation about this horizontal transverse axis.
- the front end 11202 of the arm 1120 is pivotally mounted around an axis of the same horizontal transverse direction on the plate 111.
- the arm 1121 is mounted in the same way on the longitudinal frame 13 and on the plate 11, in order to form the parallelogram 112 which moreover comprises a device for adjusting the orientation of the arms 1120 and 1121, constituted here by a jack 1122. Thanks to this jack, it is possible to adjust the height of the front of the chassis 13 relative to the plate 111 and therefore to the track train 11. In this way, the pitch is adjusted in orientation chassis 13.
- the parallelogram 112 can be replaced by any means of controlled adjustment of the height of the machine relative to the track train 11, such as a column with vertical sliding for example.
- the machine 10 also comprises, as shown in FIG. 2, a third crawler train 14 which is mounted without the possibility of rotation under a transverse frame 15, said transverse frame itself being made integral with the longitudinal frame 13 in the manner specific to a embodiment of the invention which will be described later in this text.
- the third crawler train 14 is shown in two different positions, this train being mounted at the end of the rod 151 of a jack 150, the body of said jack being fixed on the transverse frame 15 and coaxial with this chassis.
- the crawler train 14 is shown in a first position in solid lines corresponding to a retracted configuration of the actuator 150, and in a second configuration in dotted lines corresponding to a deployed configuration of the rod of the jack, so as to separate the position of the track train 14 from the longitudinal frame 13.
- this arrangement makes it possible to adjust the transverse balancing of the machine, as a function of the position of the on-board tool and / or of the configuration of the machine.
- sliding is meant here that the concrete which is deposited by the tool on the ground slides relative to the formwork mold 16 inside thereof, said mold itself being movable relative to the ground for extrude structures such as low walls, curbs, or any other profile.
- the sliding formwork mold corresponds to a preferred embodiment of the invention, it is specified that according to the invention the tool on board the machine 10 may be different from a formwork mold; it can be any type of tool intended for carrying out operations in the field, such as the tools mentioned in the introduction to this text.
- the machine 10 comprises three crawler tracks 11, 12 and 14 which constitute an “L”, the transverse chassis 15 being perpendicular to the longitudinal chassis 13. This “L” configuration appears more particularly in the top view of FIG. 3.
- the transverse frame 15 is not fixedly mounted on the longitudinal frame 13, but on the contrary by means of a plate 17 capable of pivoting about a vertical axis A by relative to the longitudinal frame and to which the transverse frame 15 is fixed. Means are also provided (not referenced in the figure) for locking the angular position of the plate 17 and therefore of the transverse frame 15, relative to the longitudinal frame 13 in a position where these two elements form an angle of 90 °, as shown in Figures 1 to 3.
- This configuration in which the tool is also fixed to the side of the longitudinal chassis 13 which is outside the "L” formed by the longitudinal chassis 13 and the transverse chassis 15, is the normal working configuration of the machine.
- the articulated mounting of the transverse frame 15 on the longitudinal frame 13 is an essential arrangement of the invention. This arrangement allows as will be explained in more detail to pass the transverse frame 15 from one side to the other of the longitudinal frame 13, and makes the machine "symmetrizable”. This allows the machine 10 to pass from one configuration to
- the machine 10 is also equipped with a heat engine M which drives the tracks through a hydraulic or other transmission, and a gangway P to allow an operator to take a position on the machine.
- the formwork mold 16 is protruding on the side of the machine and can be used for the production of works located at the edge of the carriageway, the machine 10 moving in the direction F.
- the crawler train 12 is fixedly mounted not directly on the longitudinal chassis 13, but on the transverse chassis 15. It is this solution which is illustrated in FIG. 4b,. either immobilize the longitudinal chassis 13 by blocking the crawler tracks 11 and 12 (the train 12 then being fixedly mounted directly on the longitudinal chassis 13), and activate the crawler train 14.
- This desired position thus ensures the quality of the sliding formwork operation, the rear 161 of the mold corresponding to the place of deposit of the concrete on the ground. This avoids the shifting of the rear of the mold relative to the ground when the machine moves along a curve.
- the structure 30 can thus have any orientation with respect to the existing structure 20, in particular a perpendicular or substantially perpendicular orientation.
