Description

Traction system for mobile platforms

Field of the Invention

The present invention relates to the system of traction of mobile platforms belonging to a system of universal and accessible transport of people / goods.

Background of the invention

Within the field of action of the systems Universal transport for people / goods are observed different proposals for the movement of the platforms or cabins of these systems. These systems are characterized by a platform movement in point-to-point rectilinear paths, as in elevators and inclined elevators, or closed and coplanar as in carousel systems. The need to solve the movement of platforms in systems of transport of people and / or goods that have other types of trajectory and transitions in different directions and senses (horizontal, inclined and vertical), as well as movements discontinuous platforms or cabins. The different methods of Existing traction does not meet movement needs required for all movement possibilities of platforms. The present invention provides a solution to the movement and platform control for transportation systems of people and / or goods.

Description of the invention

The present invention relates to a system universal and accessible for the transport of passengers / merchandise that it comprises a series of platforms and more specifically to the subsystem tractor in charge of the movement of the platforms.

To understand the object of the invention, one must first study the operating cycle of one of the system platforms, starting at the boarding position of passengers, area in which passengers access the platform located in horizontal position. Then the tour begins from the platform along the way, which can be tilted, where the platform moves parallel to the ground to ensure the horizontality of the platform or cabin, and allow a level of adequate passenger comfort. When the platform reaches the area landing, the platform remains in a horizontal position so that passengers can leave the platform so comfortable. Once the passengers disembarked, the platform is displaced horizontally towards the lifting area upper, where an elevator system positions the platform to make the way back. The platform performs the path of return with its ground in parallel position to the inclined plane to reduce the height of the system structure in the central section (it is understood by central section the one between the zones of embarkation and disembarkation).

Said return path consists of a section upper horizontal, an inclined section and a horizontal section lower. After reaching the platform to the lower zone, the platform is moved to the lower elevation area where, through a lifting system, the platform is placed on the road useful or outbound and allow passenger boarding. It would start from New cycle of platform displacement.

The movement cycle described above by the platforms it is carried out by two tractor systems independent, according to the trajectory that is carried out by the platform:

- A first tractor subsystem is necessary to get a first trajectory in horizontal planes, in the embarkation and disembarkation areas, both at the road level of return as at the level of the transport road;

- A second tractor subsystem is necessary to get a second trajectory on inclined sections, both at the transport road level as at the road level of return.

The independent tractor systems are synchronized with each other to allow transitions of platforms in the different trajectories. This synchronization it should also allow a symmetrical movement of the platforms that are displaced on the inclined path to get a compensation of weights and less power needed in the system tractor formed by roller chain, that is, at the time that the boarding platform begins its upward movement inclined, the landing platform starts its inclined downward movement.

The first subsystem comprises linear motors As a tractor element. The second tractor subsystem comprises mechanical transmission systems of roller chains.

The transition between the tractor subsystems is performs through a guidance system on which some rollers placed in the lower outer part of the platforms. Said guidance system is continuous in the horizontal sections and inclined and is discontinuous in lifting systems to allow the change of trajectory of the platform from the plane horizontal inferior to the superior horizontal plane and vice versa, allowing an up / down movement of the platform. Therefore the lifting systems have guides installed configured to allow the transition of the platform from the horizontal zones to the elevator system itself. This system of guides rests on fasteners that in turn are anchored to the bearing structure of the system, which gives it the rigidity necessary to support the efforts to which the guidance system

The subsystem responsible for providing movement to the platform in the horizontal parts of the system comprises a linear motor or a set of linear motors located at the end of the elevator, which acts on a series of plates magnetic located at the bottom of the platform, closing the magnetic circuit of the linear motor. These linear motors are configured for platforms:

are displaced horizontally towards elevators:

from the mechanical traction subsystem of the inclined section that comes from return path in the boarding area;

from the mechanical traction subsystem of the inclined section that comes from useful or transport road in the landing zone;

are displaced horizontally from elevators:

until the mechanical traction subsystem of the inclined section that goes to the road of transport in the boarding area;

until the mechanical traction subsystem of the inclined section that goes to the road of return in the landing zone.

The subsystem that is responsible for providing movement to the platform in the inclined section comprises a variety of elements whose main drag part is a roller chain that rolls on a guide to control its position at all times. A mechanical element or hook installed on each platform is connected to this roller chain to allow the platform to be hooked and dragged by the roller chain. The roller chain is located on both sides of the platform to allow a symmetrical shot and this roller chain is driven by two sprockets driven by a motor-reducer assembly. The two sprockets are supported to the structure by the outer part of the wheels, to allow the platform to pass through the inner part of the sprockets. These wheels are supported by
