JP4917266B2 - Trajectory change device for tire vehicle - Google Patents

Description

  The present invention is particularly suitable for a local train (bus) exclusive route (lane) using a tire vehicle, in which an inclined double roller device fixed to the vehicle and a single central rail cooperate to perform guidance. With respect to the transportation field, an object is to provide such a trajectory changing device for a vehicle.

  In order to form a route, a guided transport network of a transport en-site route is inevitably provided with a track changing device.

  Such a trajectory changing device is often used in a transportation means using two parallel rails of a railroad or tram type.

  The invention relates in particular to a transport means using only a single central guide rail, which has a profile that cooperates with a double gallet inline means fixed to the vehicle, avoiding any derailment. Guidance can be made to do.

  For this reason, various branching devices with a central rail are known. Thus, EP 0 844 329 describes a directing device which makes it possible to carry out a trajectory change in a vehicle equipped with a roller with a directional control double flange.

  However, such a device requires a guardrail so as to guide the whole continuously like a normal track. Furthermore, since the device according to this document is of a type having a vertical guide surface, it is necessary to apply a strong vertical load to the rollers in order to cooperate properly during the guidance while largely avoiding the risk of derailment.

  In addition, a configuration of a branching device for a guide device is known, in particular from French Patent Application No. 2662450, in which a roller travels along an ornier. However, such a configuration cannot be applied to the case where guide means including an inclined double roller is used or where the guide means is installed on the road surface for road travel.

In general, the trajectory changing apparatus that exists at the present time has a rather complicated structure and a heavy structure, which increases manufacturing costs.
European Patent Application No. 0844329 French Patent Application Publication No. 2662450 Specification

  The present invention is a tire vehicle guided through a single central rail that is capable of providing a comprehensive continuous guidance that is not derailed in the same manner as a normal track, although having a relatively simple configuration. An object of the present invention is to provide a trajectory changing apparatus for solving the above-mentioned drawbacks.

  For this reason, the trajectory changing device for a tire vehicle in which the inclined double roller device fixed to the vehicle and the single central rail perform the guidance is mainly used for the straight rail piece (section, troncon) and the curved line. A plate supporting a rail piece and having a pivot on the back; a mechanical actuating means for the plate; a box (caisson) including a bearing for receiving the pivot of the plate by receiving the plate and the mechanical actuating means; Locking means comprising an inlet / outlet rail welded to the box and an upper closing metal plate of the box flush with the road surface, and further comprising a lock control means and a safety and position control means These means are housed in the box.

  The invention will be better understood from the following description, given by way of example and not limitation with reference to the accompanying drawings.

  The attached FIGS. 1 and 2 show a trajectory changing device for a tire vehicle, in which a tilted double roller device fixed to the vehicle and a single central rail cooperate to provide guidance. , Mainly, a plate 1 supporting a straight rail piece 1 ′ and a curved rail piece 1 ″ and provided with a pivot (not shown) on the back, a machine operating means 2 of this plate 1, a plate 1 and a machine A box 3 containing a bearing 4 that accommodates the actuating means 2 and receives the pivot of the plate 1, an inlet / outlet rail 5 that is welded to the box 3 and is also called a branch line (antenna), and a box that is flush with the road surface 3 upper closing metal plates 6.

  According to the invention, this device further comprises a locking means 7 having a lock control means 20 and a safety and position control means 17, which are accommodated in a box.

  Advantageously, a box 3 for accommodating the plate 1 and the machine actuating means 2 is constructed by assembling a thick machine-welded metal plate and forms the framework of this device.

  The mechanical actuating means 2 of the plate 1 is configured as an electrohydrodynamic assembly comprising a pumped tank 2 ', the pump being submerged in said tank and jacked via a hydraulic distributor. The machine actuating means 2 may be configured as an automatic electric jack, as is well known.

  In particular, the locking means 7 shown in the attached FIGS. 3 and 4 is of a type axial type and is configured as a link device connected to the rod end of the jack 2 ″ of the mechanical actuating means 2 of the plate 1. This linking device comprises a crank lever 8 that is rotatably attached to the box 3, one end of which cooperates with the rod end of the jack 2 ″ in cooperation with the slider 9, and the like. At the end, in cooperation with a barre decalage 10 which is held translatable in the box 3 by two hooks 12 via a guide device 11, said hooks are fixed bar 10 and a stopper 13 fixed to the box 3 parallel to the sliding axis of the fixed bar 10. Work.

  1 and 4 in particular, the lock control means 20 provided on the lock means 7 is advantageously provided with end-of-stroke electrical contacts (contacts) assigned to one of the two end positions of the fixing bar 10, respectively. de fin de course electres).

  One end of the crank lever 8 cooperating with the slider 9 is provided with a roller 8 ′ guided by a lateral groove 9 ′ of the slider 9, and the other end of the lever 8 is a roller 8 cooperating with the operation fork 10 ′ of the fixed bar 10. In this way, when the piston rod is moved by the operation of the piston 2 ", the crank lever 8 moves the assembly shaft in the box 3 by guiding both ends of the crank lever through the rollers 8 'and 8". It can be easily rotated as a center, and this guide allows the roller to move along a curved track.

  The hook 12 is configured as two opposed levers that are coupled to the central slider 14 at one end, and the other end is a side that continuously cooperates with the fixing bar 10 and the stopper 13 that is fixed to the box 3. The middle slider 14 is provided with an interlocking stopper or interlocking rib provided on the inner surface of the plate 1 on the surface opposite to the bottom of the box 3 (bute ou nerve d'entrainment) ( Two pins 16 are provided for tightening (restraining) a device (not shown) with a functional play (jue function). When the lock means 7 is actuated via the jack 2 ″ by the cooperation of the pins 16 and the stoppers or ribs of the plate 1, the plate is rotated by the lock means.

  Each end of the hook 12 cooperates with the fixed bar 10 via one of the inclined stoppers 15 protruding laterally by corresponding grooves 10 ", and the side surfaces of the grooves are inclined to the inclined stopper 15 protruding laterally. The groove has a corresponding inclination and the width of the groove is wider than the width of the laterally projecting inclination stopper 15. Thus, as shown in FIGS. It comes to the position of cooperation entrainment and the position of fin de cooperation with the fixed bar 10.

  The end position of the fixed bar 10 is detected by a set of stroke end electrical contacts respectively assigned to one of the two end positions of the fixed bar 10, and this set of electrical contacts is a lock control means provided in the lock means 7. 20 is configured.

  Advantageously, the safety and position control means 17 is configured as a double-coupled electromechanical sealing sensor and is connected via a link device 17 ′ to a detection stopper 17 ″ coupled to the plate 1. (FIG. 4).

As shown in the attached FIGS. 5a to 5c, when the locking means 7 is actuated via the jack 2 ″ of the mechanical actuating means 2 of the plate 1, the jack 2 ″ causes the fixing bar 10 as shown in FIG. 5a. Move to the right, or move to the left (Fig. 5b) via an intermediate position (Fig. 5c).

In the first case, i.e. the arrangement transitioning to a linear track (Fig. 5a), the crank lever 8 is actuated to the left. As shown in FIGS. 3 to 5, the slider 9 is driven when the rod of the jack 2 ″ is completely ejected, and the roller 8 ′ at the corresponding end of the crank lever 8 is moved through the transverse groove 9 ′ of the slider. For this reason, the other end of the crank lever 8 similarly drives the fixing bar 10 to the left via a roller 8 ″ cooperating with the fork 10 ′ of the fixing bar 10. As a result, the hook 12 extending to the right with respect to the slider 14 and the pin 16 holds one of the inclined stoppers 15 protruding laterally in the corresponding groove 10 ″, and the other of the inclined stoppers 15 protruding laterally is the stopper 13. in by supporting the corresponding end cooperating with the groove 10 of the coming. stopper 15 to the driving cooperation position with the fixed bar 10 "wall of the groove 10 'inclined in the direction to fully engaged the stopper 15 in Therefore, the fixed bar 10 drives the pin 16 to the right side via the hook 12 and the slider 14, and as a result, the plate 1 rotates about the bearing 4 and the linear rail piece 1 'corresponds. In this position, the other hook 12, which is first driven by cooperation with the corresponding groove 10 ", reaches the end of the stopper 13 and this end. When the movement of the fixing bar 10 and the slider 14 is finished, the stopper 15 protruding laterally from the groove 10 "moves below the corresponding edge of the groove 10" by its outer edge. Thus, the hook 12 is held at a position beyond the stopper 13.

  As a result, the slider 14 with the pin 16 is blocked at its end position, so that no action is taken even if the plate is actuated via the vehicle guide device working with the plate 1, that is, cooperating with the rail piece 1 ′. It does not occur, i.e. the rotation of the plate 1 is impeded and locked all over.

  FIG. 5c shows, for example, the locking means 7 in an intermediate position corresponding to the position change of the plate 1 from the position shown in FIG. 5a to the position shown in FIG. 5b.

  Here it can be clearly seen that the fixing bar 10 has been moved to the right in order to reach such an intermediate position. As a result, first, the fixing bar 10 moves starting from the position of FIG. 5a, and the hook 12 and the slider 14 that support the pin 16 remain as they are.

  When the right wall of the groove 10 ″ cooperating with the left stopper 15 contacts the corresponding wall of the stopper 15, the groove 10 ″ assigned to the corresponding stopper 15 of the other hook 12 faces the stopper 15. . Then, the stopper 15 of the right hook 12 is always moved by the movement of the left hook 12 and the left hook is held by the stopper 13 in the groove 10 ″. I can enter. This is because the inclined surface of the stopper 15 facing the left hook is slid by the stop of the stopper 13 and supported by this stop.

  As a result of the movement movement to the position shown in FIG. 5b, the slider 14 and the pin 16 are driven by the right hook 12 until reaching the position corresponding to the branch line at the end of the movement. At the branch line, the curve 1 ″ cooperates with the corresponding inlet / outlet rail 5.

  In this position, locking and locking is performed as described with respect to FIG.

  According to another characteristic of the invention, the device further comprises manual operating means 18 comprising a lever connected to the bottom of the box 3, which operating means 2 is a jack 2 in the mechanical actuating means 2 of the plate 1. The slider 9 is connected to the end of the piston rod, and advantageously the lever comprises an operating handle or equivalent (not shown) fixing device, Constrained to the same height and operable via the corresponding opening 6 'of the closing plate 6, the opening 6' is secured via an electrical start-up device when opened. Such a safety device is particularly configured to cut off the power supply of the device when the trap (lid) is opened. In particular, as shown in the attached Figures 1, 3 and 4, a sleeve or equivalent securing device can be configured as a simple hole into which such a sleeve is inserted.

  Furthermore, the device according to the invention comprises an automatic heating device that brings the internal temperature of the box to a non-freezing temperature, in particular with respect to the movable element and the hydraulic pipe.

  As is well known, the device is fed via a tight electrical connection case that leads to the interior of the box 3 via a cable passage 3 ', and the control means is fed via a cable passage 3 ". Performed (FIG. 1) The electrical insulation of the box 3 with respect to the ground is performed by an insulation coating, while the flexible cable (not shown) is a rail consisting of a plate 1 and rail pieces 1 ′ and 1 ″. The strip and the box 3 are electrically continuous. Furthermore, the box is also provided with a discharge hole 19 (FIGS. 3 and 4) in the lower part which can be connected to an existing sewer network, as is well known.

  According to another characteristic of the invention, particularly as shown in the attached FIGS. 1 and 3, advantageously, the inlet / outlet rail 5 is provided with a means for preventing longitudinal displacement extending transversely to the rail 5. ) 21. The longitudinal slip prevention means 21 is configured to absorb and block residual movement that may occur with the welded long distance rail, thereby protecting the tip and end of the device.

  According to the present invention, it is possible to realize a branching device that collects and guides all the steering elements, fixed elements, and control elements in the box, so that the external dimensions of the branching device on the road surface are significantly reduced. The tire and the vehicle guided in this way travel without contacting the closing metal plate of the branching device. As a result, great advantages are obtained with respect to noise and with respect to maintenance of the cover of the device constituting the branching device.

  Further, the structure of the locking means 7 itself, in particular, the pin 16 is provided, and the longitudinal displacement prevention means 21 keeps a good resistance against the strong force transmitted from the guide device mounted on the vehicle, thereby completely positioning the device. can do.

  Moreover, since the obtained apparatus is small (compact), the branching device configured with the minimum inter-axis distance in the engine zone can be installed on the vertical track.

  Finally, the groove of the device according to the invention can be very shallow, i.e. it can be the same as a normal track, which increases the safety of pedestrians and other users, especially bicycle users, and the device is completely road surface. Incorporated into.
