  • the object of the present invention is a traction system of reduced dimensions for elevators that is installed completely between the walls of the hole and the cabin, without affecting the free space above the hole, known as escape, or the free space in the part lower hole known as pit. Thanks to the fact that the traction system is completely located between one of the walls of the hole and the cabin, the use of the area of the hole is maximum, and also does not require special dimensions for the escape and the pit, makes the system a system of ideal traction for buildings in rehabilitation in which the existing holes were not originally designed to house an elevator, as well as in new buildings that require special construction requirements.
  • the traction system has a backpack type chassis, where all the machinery and guides are on one side, that is, in the space between one of the walls of the cabin and the facing wall of the hole, with such a design that the entire traction system has a reduced width, allowing optimum use of the elevator shaft.
  • the proposed traction system has the following characteristics:
  • the traction is carried out directly on the counterweight by means of a closed loop of a belt or cable pulled by adhesion, while the traction of the cabin is carried out indirectly through the counterweight by means of suspension cables.
  • the traction is carried out on the counterweight by means of a closed loop system where the draft ratio can be from 1: 1 to 4: 1, using a small size tractor pulley that reduces the necessary torque.
  • the tension that is necessary to apply to said loop to obtain adhesion can be obtained in different ways, being initially preferred in which the lift's own weight participates, by means of a cam system, this greatly simplifies the solution and, above all, does not it implies space, as other dock alternatives, counterweights, etc. can do.
  • the cam system has an important peculiarity.
  • the rotation of the cam has a degree of freedom in only one direction, the one that provides tension to the belt.
  • the cam is mechanically locked in such a way that it prevents the loss of tension when the elevator is operating with different loads, that is, the tension is fixed for the maximum load in the cabin and does not release when it is empty.
  • the motor has reduced dimensions, particularly a reduced depth, using either a motor whose rotor directly acts on the tractor pulley (direct traction), or using a pulley.
  • tractor unit separated from the engine, connected by a reduction of parallel shafts, such as a toothed belt.
  • Reduced compensation factor In most elevators, 50% is set as a compensation factor, that is, the weight of the counterweight is equal to the weight of the cabin (P) plus 50% of the load of people (Q); P + 0.5Q .. This means that the device consumes the maximum of its power during empty down paths (very frequent). However, traffic studies show that minor counterweights, between 30-35%, would achieve a better energy balance.
  • the suspension of the lift is carried out by means of two suspension pulleys, which requires a more or less centered arrangement of the counterweight with respect to the cabin, so that the necessary surface area of the traction system is clearly reduced. traction ma presents as constructive characteristics
  • Traction transmission means which can be cables or traction belts and which in a possible preferred but not limited embodiment, are at least two tension belts, which, starting from a higher fixing point, pass through an upper pulley of the counterweight, by the tractor pulley, to continue to a forwarding pulley mounted in the lower part of the hole, to continue to a lower pulley of the counterweight and finally to be fixed its end end in the lower part of the hole.
  • a cam system arranged in the suspension pulleys of the cab, with the particularity that they have limited rotation in one of the directions, which provides the necessary tension to the traction loop so that it has the necessary adhesion in the tractor pulley and the motor torque can be transformed into vertical movement of the cab.

  • the traction assembly in a second embodiment, as shown in Figure 7, consists of a motor (1) that moves through a toothed belt (21) a reduction pulley (22) in whose interior would be the traction sheave of the elevator (4), the engine pulley (1 .1) and the traction sheave of the elevator (4) being arranged with its axes in parallel and occupying the smallest possible width

  • the fact that the suspension is made with two separate cable branches provides two advantages, the first is that the size of the elements can be reduced and located in a more optimized way. The second is that it improves the centering of the cabin and counterweight shots which results in a better functioning of the system by reducing friction in front of a system where the shot is off center.

  • Figure 5 shows the presence of a lower cross member (5.1) of the counterweight, and on which the lower pulley (12) of the counterweight is fixed.
  • figure 6 it is worth noting the presence of the forwarding pulley (1 1) fixed at the bottom of the hole.
  • FIG 7 an alternative way of transmitting the traction to that shown in Figure 1 is shown, and which falls under the same principles of the invention, which consists in that the traction of a motor (1) is transmitted from the motor pulley (1 .1) to a reduction pulley (22) by means of a toothed belt (21), the motor pulley (4) remaining inside the reduction pulley (22) with a smaller diameter.
  • the motor pulley (1 .1) must be arranged so that its axis is parallel to that of the reduction pulley (22).
  • the main advantage of this system is the resulting morphology, where the engine, due to the intermediate reduction, reduces its size and can placed sideways, which allows the machine to be perfectly integrated into the assembly.

Abstract

La présente invention concerne un système de traction ayant des dimensions réduites pour des ascenseurs qui comprend: un moteur (1) chargé de transmettre le mouvement à un système de traction au moyen d'une poulie de traction (4); lequel système de traction effectue ladite traction sur un contrepoids (5) par l'intermédiaire de moyens de transmission de la traction (7) disposés en boucle fermée; un système de suspension de cabine (14) et de contrepoids avec des câbles de suspension (8), la traction de la cabine s'effectuant de manière indirecte par le biais du contrepoids, la tension à appliquer à la courroie de traction étant créée au moyen d'un système de cames pouvant uniquement tourner dans le sens de fournir de la tension (6), tous les éléments étant disposés et logés entre une des parois de la cage de l'ascenseur et la paroi de la cabine située en face. Cette invention permet d'optimiser l'utilisation de la surface de la cage de l'ascenseur, ce qui est d'une très grande utilité dans des bâtiments déjà construits soumis à une rénovation dans lesquels la cage de l'ascenseur est réduite et il n'existe pas d'espace pour la fuite ni de fosse.
