    VEHICLE HOLDER SYSTEM WITH ANGLE POSITION LOCK MECHANISM

    DESCRIPTION
    Field of the invention 5
     The present invention relates to vehicle transport systems. Specifically, the vehicle transport system of the present invention has a mechanism for blocking the angular position of the platform on which the vehicle is arranged allowing the angle lock when the platform rotates both clockwise and counterclockwise on a axis of rotation. 10
    Background of the invention
     At present there are many platforms adapted for transporting vehicles both by rail and road vehicles. Said platforms are specially designed to be able to transport the load in two or more levels of height being adaptable to be able to load both vehicles and merchandise in the same cargo space 15 and which allow different movements to be made.
    The transport of cars is generally carried out on platforms where the only modularity they present is to be able to perform a manual adjustment of the position of the supports by means of manual mechanisms, where the tires of the different vehicles will fit to carry out the load, depending on space they occupy or volume 20 of the cargo to be transported.
    However, at present, the movement of the platform once loaded requires a great effort and, consequently, reinforced materials that can withstand the effort required for the movement of the platform. Additionally, it is necessary to control the inclination of the platforms in order, on the one hand, to optimize the use of the available space and, on the other, to increase the safety for the personnel and the integrity of the vehicles.
     The present invention has the objective of making known a vehicle transport system that has a mechanism for blocking the angle of rotation of the platform intended to receive the vehicle. 30

    Description of the invention

     The locking mechanism of the invention is designed to fix and secure the angular position of a platform that has a rotational movement with respect to an axis of rotation in a transverse plane of the platform. At one of its ends, the mechanism 5 is jointly and severally connected to the platform and at the other of its ends it is connected so that it can rotate on a support structure. The locking mechanism of the present invention has a locking capacity in any angular position required for its use and in both directions of rotation of the platform, both clockwise and counterclockwise. 10
     In a particularly advantageous embodiment, the angle of rotation locking device is formed by a linear actuator, for example, a hydraulic or pneumatic cylinder or a solenoid, said linear actuators comprise actuation means and a rod in this case. It has a mechanism for locking the longitudinal distance to which the rod is extended. fifteen
    Preferably, the linear actuator is integrally connected to the support structure, by means of joining that allow its rotation around an axis of rotation, for example, perpendicular to said support structure.
     The rod belonging to the linear actuator, moves telescopically through the inside of a cylinder and at its end is attached to the platform, preferably, so that just like the hydraulic cylinder can rotate with respect to the platform.
     In a particularly preferred embodiment, the linear actuator is a hydraulic cylinder whose oil inlet and outlet connections are joined by a single conduit, so that a closed hydraulic oil feed circuit is created. Thus, while the circuit remains open, the cylinder and the rod accompany the movement of the mobile platform without generating any resistance, however, when closing the circuit a constant pressure is maintained that blocks the extension of the rod and, consequently, it blocks the platform at a certain angular position.
    In this way the mobile structure is related to the fixed structure by means of a mechanism that allows it to rotate freely until it is locked. 30
    Said blocking or closing of the circuit is carried out, for example by means of an electrovalve, so that when the position desired by the mobile platform is reached, the signal is given so that this solenoid valve is closed, thus preventing free
    Hydraulic oil circulation, blocking the telescopic movement of the rod inside the cylinder and the position of the mobile platform being fixed.
     The device of the invention comprises at least one hydraulic cylinder located on one of the sides provided with the necessary locking means, both of the solenoid valve and of the manual closing by means of a stopcock. 5
     The system can comprise two similar locking mechanisms located on both sides of the mobile platform, with their corresponding elements for fixing the inclination.
     In a second alternative embodiment, the operation of the present invention is carried out by means of a rod of a fixed length that travels through a guide element, accompanying the movement of the mobile platform.
    Said guided element has at one of its ends a rod, this rod preferably has a circular cross-section and is joined in a perpendicular manner perpendicular to the fixed structure, this rod serving as a pivot axis for the guided element on the fixed structure. This guided element travels through the interior of a bushing, in turn joined in solidarity with the mobile platform so that it can also rotate on an axis perpendicular to said platform.
    In this way, the guided element travels longitudinally through the bushing and, on the other hand, has a rotational capacity with respect to the support structure. In this way, the guide, when moving through the inside of the bushing, moves by 20 platform action, not restricting at any time its movement.
    The guided element can be a solid rod threaded by its outer surface, made, for example, in some steel alloy, in this way there is more friction surface between the guide and the element to be guided, that is, the bushing, offering greater clamping surface 25
    Said bushing can have a second inner bushing made of some type of non-slip material, such as PVC, attached to a clamping system, such as a clamping screw. When the system is in the desired position, to fix the position of the mobile structure with respect to the fixed structure, simply tighten the screw, which makes a compression force on the bushing that envelops the guide element, preventing in this way the guide moves through the inside of the bushing and blocking the position of the moving element.
     Preferably the guided element has a substantially circular cross section. Both the outer bushing and the inner bushing have the same cross section as the guide element, in order to be able to make their coupling.

    Detailed description of one embodiment
     Figure 1 shows a first exemplary embodiment of a platform (1) for use in a car carrier system according to the present invention. Specifically, the platform (1) has means for fixing the platform at a certain angle of rotation with respect to a support structure (16). The system mainly comprises the support structure (16) and the platform in which the support structure is preferably a fixed structure, for example, a structure jointly and severally connected to a car carrier and the platform is connected with turning capacity 30 to said support structure. Additionally, the system has a rotation motor whose function is to exert a rotational force on the platform to perform the rotation of the platform with respect to an axis of rotation.
    In order to mechanically interlock the platform at a certain angle of rotation, the platform has a locking mechanism, preferably, on each of its sides. In the view of figure 1 the platform is in an initial position, that is to say substantially horizontal.
    Figure 1 shows that the platform (1) that has a rotation movement around at least one axis of rotation (2). Said rotation axis (2) is defined by the joints with rotation capacity between the platform (1) and the support structure (16).
    Additionally, the system has locking means which, in the embodiment of Figure 1, comprise a hydraulic actuator (5) which, in turn, has a rod (6) whose extension length is defined by the internal pressure of a fluid in the 10 hydraulic actuator (5). Said hydraulic actuator is connected with rotation capacity to the support structure by its base at a remote point to the axis of rotation and, in addition, it is connected by its rod (6) to the platform (1) also with rotation capacity. .
    One of the main aspects of the present invention is that the actuator is attached to the support structure at a remote point to the axis of rotation and the rod of said actuator is attached to the platform. In this way it is achieved that, if the actuator (5) is left free, it does not exert any force on the platform and as said platform rotates, the rotation of the platform extends or retracts the rod. However, by locking the rod at a certain extension distance, said rod 20 (6) prevents the platform from rotating (1), blocking it in its current position. In this way, a locking mechanism is obtained at any angle of the platform by means of a digital system, that is, on / off.
    An example of a union with rotation capacity can be seen in greater detail with reference to Figures 2 and 3 in which the support structure (16) has a hole through which a cylinder (3) passes. The fixing is done, for example, through a bearing (not shown) coupled between the outer surface of the cylinder and the inner surface of the hole (4). Another type of union with rotation capacity is found in the joints of the hydraulic cylinder, in this case the joints have a fixed part and a rotating part in which the fixed part is a U-shaped profile (7, 9) joined jointly and severally with the platform and the support structure respectively and a rotating element (8, 10) which provides the profile with said rotational capacity, such as a bearing.
    Additionally, a detail of an example circuit is shown in Figure 3
    hydraulic for the actuator (5), it is important to note that one skilled in the art could extrapolate the hydraulic circuit of Figure 3 to pneumatic and / or electrical circuits without using any inventive activity.
    The circuit of Fig. 3 comprises a recirculation (13) connected between the inlet and outlet points of the cylinder by means of hydraulic connections (11, 12) so that when the solenoid valve (15) and the safety valve (15) are open A closed circuit is created that allows the hydraulic actuator (5) to not generate any kind of force and only accompanies the movement of the platform (1) as long as it does not need to adjust or fix its position.
    To block the turning position of the mobile platform (1) when necessary, the solenoid valve (14) or the safety valve (15) is closed, so that when the platform reaches the desired position, a signal is emitted to the solenoid valve (14) (for example, an electrical signal) to cut the oil passage circuit through the conduit (13), so that the displacement of the rod (6) through the inside of the cylinder (5) is blocked, the rod being fixed and, consequently, the rotation of the platform (1) with respect to a fixed structure (16). fifteen
    As mentioned above, as a safety element for blocking the angle of rotation, a valve (15) or manual stopcock is installed in the recirculation (13), in the event that any solenoid valve (14 ) does not work properly, the system can emit a warning signal and the circuit is closed manually using this valve (15). twenty
     To resume the rotation of the platform (1), the signal is simply given to the solenoid valve (14) to open the oil passage circuit, allowing both the rod (6) and the cylinder (5) to accompany the movement again of the platform (1). If you have used the manual locking system using the valve (15), simply open the valve (15). 25
     An exemplary embodiment of the present invention is shown in Figure 4 in which the platform (1) rotates clockwise thanks to the action of a rotation motor (19). This figure shows how the rotation of the platform forces an extension of the rod (6) of the hydraulic cylinder (5). Furthermore, it can be seen how the rotating elements (8, 10) allow the rotation of the different elements of the hydraulic cylinder that allow the rod (6) 30 to move with the platform (1). In case of requiring the lock in the position in which the platform in figure 4 is located, it is enough to close the solenoid valve (14) or the valve (15) since, in this way, the cylinder maintains the current hydraulic pressure and the
    passage of oil through the recirculation (13) which would prevent the extension or retraction of the rod (6) and, consequently, the platform (1) at the current angle of rotation would be blocked.
     Figure 5 illustrates that the platform (1) can be locked by the mechanism of the present invention regardless of the direction of rotation of the platform or the angular position. Figure 5 shows that the cylinder (5) would work analogously 5 even in clockwise movements and in any angular position of the platform.
     In Figures 6 and 7, another embodiment of the present invention is shown. In this example, the actuator (5) has been replaced as an interconnection element with the rod extensible by a rod (20), in addition, in this exemplary embodiment there is a guide element (21) through which it travels longitudinally the rod (20). The operation of this exemplary embodiment differs from the examples described above in that, instead of blocking an actuator to prevent the extension / retraction of a rod, the rod is locked to prevent its longitudinal displacement. In this case, the blocking is carried out by means of a clamping system (22).
    Although the exemplary embodiment is shown in the figures with a tubular and threaded shape along its entire outer surface, other shapes are equally conceivable. The guide element (21) is attached to the fixed structure (16) so that it can be rotated by means of union with rotation capacity (23) to adjust to the orientation of the rod (20).
     The guide element (21) may have the clamping system (22). While it is not necessary to fix the position of the mobile platform (1), the clamping system (22) remains unadjusted to allow the rod (20) to slide between the guide element (21).
    The guide element (21) can have at least one non-slip inside to ensure maximum support.
     As for the joints to the elements of the platform, the rod is attached to the support structure (16) by means of joining with turning capacity (24) which, in this case, is a through element through a hole. Alternatively, said joint may comprise a bearing.
     The tightening system (21) can be done through an electric motor, which receives the operating signal once the platform is in the desired position.
     Once the mobile structure (1) is to be rebalanced, the tightening screw (26) is loosened, according to the exemplary embodiment, by means of the electric motor, and the
    Turn blocking device (26) no longer exerts any influence on the mobile structure (1), moving in solidarity with it in the turning movement it makes, but without being any impediment to its movement.
    In a particularly preferred embodiment, the car carrier system according to the present invention has data processing means that are connected to the rotation motor and the locking mechanism (be it the solenoid valve, the clamping system or any other means). lock) so that the user can select the desired angle of rotation. Subsequently, the rotation motor drives the platform causing it to rotate and, once it has reached the desired angle, sends a signal to the locking means to thus block the platform at the desired angle 10.
    In short, the present invention discloses a vehicle transport system of the type comprising a platform adapted to receive a vehicle, a support structure and a turning motor, the platform being attached to the support structure so that the platform can rotate around an axis of rotation per action of the motor of rotation. In addition, the system object of the present invention comprises blocking means which, in turn, comprise:
     means of attachment to the support structure with rotation capacity with respect to the structure at a point remote to the axis of rotation
     means of joining platform 20
     a connecting element attached to the means of attachment to the structure and the means of attachment to the platform
     a locking mechanism of the connecting element in at least two longitudinal positions of the connecting element.
     25
    Similarly, the means of attachment to the platform may have rotational capacity with respect to the platform.
    In a first exemplary embodiment, the connecting element is a linear actuator, for example, a hydraulic or pneumatic cylinder.
    On the other hand, the blocking means of the connecting element may comprise means for maintaining the substantially constant hydraulic pressure in the cylinder, for example, by blocking an oil recirculation in the cylinder by means of such a blocking valve. Like a solenoid valve

    Alternatively, the linear actuator can be a solenoid. In this case, the blocking means of the connecting element may comprise a switch and a power supply.
    In another embodiment of the present invention the linear actuator comprises a rod and the platform attachment means have a ring or guide element through which the rod passes. In this case, the locking mechanism may comprise a rod fixing element to the ring in at least two longitudinal positions of the rod. The fixing element of the rod to the ring can be manual or a fixing element of the pneumatic, hydraulic and / or electrical type.
