Definitions

  • the present invention relates to a guideway transfer switch for a people mover or other transportation system.
  • a guide rail is provided with the guideway to coact with the vehicle to guide the vehicle along the guideway.
  • Prior art guideway switch arrangements such as transfer tables and rotary guide switches, such as described in U.S. Patent No. 4,970,962, are well-known in the art.
  • a transfer table is a movable table to which the guide track is secured. The table can either rotate about an axis or move in a lateral direction to enable a vehicle to change tracks.
  • These prior art transfer tables are very heavy and require a substantial amount of lead time to transfer the vehicle.
  • a transfer table weighs on the order of 30,000 pounds.
  • the transfer table actually moves the guided vehicle as it is changing tracks. This is a time-consuming and cumbersome procedure.
  • previous switches require significant structural support due to weight or deep pits which increase the cost of the structure.
  • U.S. Patent No. 3,672,308 teaches a transfer switching arrangement having fixed tracks and movable guide tracks.
  • the switching arrangement operates in a first and second position for guiding a vehicle between fixed tracks.
  • the first and second positions are accomplished using a straight guide track and a curved guide track within the switch.
  • the switch is secured by lock pin arrangements located between the strai ⁇ ht and curved guide tracks . While the prior art switches provide for lateral and vertical support of the guide tracks, they do not prevent overturning of the guide tracks due to vehicle forces through the switch (i.e., rotation in the direction of the moment) .
  • the prior art switches do not prohibit racking (where one end of the switch moves prior to or more quickly than the other, causing rotation of the guide tracks in the horizontal plane) during switch movement from position to position. Therefore, it is an object of the invention to overcome the deficiencies of the prior art .
  • a guideway switch made in accordance with the present invention is a transfer switch type.
  • the design of the transfer switch features continuous uninterrupted power collections and allows maximum system speeds in the tangent position. In the turnout position, the radius of curvature limits the train speed to maintain passenger comfort. The ride quality of the vehicle is maintained through the switch in both tangent and turnout directions.
  • Guidance of the vehicles through the switch is accomplished using one, preferably two, of a plurality of movable guide tracks, for example, a curved and a straight guide track, each identical in cross-section to a fixed guide track.
  • the fixed track and the movable guide tracks are located at the same elevation (i.e., contained in the same plane) .
  • Switching is performed by shifting the selected movable guide track into position so that its free ends are aligned and locked with the fixed guide track adjacent to the switch.
  • the fundamental switching action involves shifting the desired movable guide track into alignment with the fixed guide track and moving the other movable guide track to a position where it will not obstruct the undercarriage of the vehicle as it passes through the switch.
  • an electromechanical drive assembly such as a hydraulic cylinder attached to a switch guide track frame and an adjacent roadway section structure. Cross beams or trolleys are fastened between the movable guide tracks. A linear bearing is located approximately at the midpoint of the switch to aid the switching action.
  • extension and retraction of the cylinder causes both tracks to transfer in unison. Full extension moves the curved track into the aligned position (switch in reverse position) and full retraction moves the straight track into alignment (switch in normal position) . Switching may also be accomplished using a chain drive assembly.
  • At least one locking mechanism preferably a pair of bolt-like lock pins, is engaged, preferably hydraulically, to join the ends of the fixed and movable tracks and provide a continuous path for the vehicle guide tires through the switch.
  • Safety is one of the most important criteria used in the design of the guideway transfer switch.
  • electromechanical devices for example, limit switches, are mounted to fixed structures.
  • the position of the movable guide tracks activates the limit switches and provides an electrical signal to the central control intelligence for proper automatic train control (ATC) operation of vehicles through the switch.
  • ATC automatic train control
  • This signal also operates traffic signal lights for use during manual operation. These lights, in turn, provide a visual annunciation of the status of the switch. If the switch is aligned in the wrong position, the corresponding signal and traffic light alerts the ATC system or an on-board operator to this condition to ensure appropriate action.
  • the on-board operator uses the traffic signal to ensure safe routing through the switch.
  • the limit switches which detect the position of the guide tracks, are designed to annunciate no signal until the track is fully aligned.
  • the absence of a signal to the ATC prevents entry of a vehicle or train through that switch and does not provide the go- ahead signal at the traffic lights.
  • a second set of limit switches detect the position of the lock pins. If the lock pins are not fully seated in the locked position, these limit switches cancel the alignment signal to the ATC and traffic lights, thereby providing the same action described previously for a guide track that is not fully aligned.
  • the guideway transfer beam switches are automatically-controlled and hydraulically-operated, they also have semi-automatic and manual control capabilities. The semi-automatic mode allows the switch to be operated by manual actuation of an electric hydraulic pump which allows the switch to be moved by one person with minimal effort and decreases the cycle time. Manual operation permits changing the switch position by use of a hand pump located in a switch control cabinet. No personnel intervention is required for control or operation of the switches in the automatic mode.
  • Local control capability and isolation from mainline traction power is provided via a hydraulic control cabinet and power disconnect, respectively, that are located in the switch area.
  • the time for one complete automatic operation cycle, including the following breakdown of train control events, is approximately six seconds.
  • a switch logic control unit located in the switch control cabinet in the switch area performs all the vital checks involved with the operation of the guideway switch.
  • the vital checks include: switch position command logic, which is used to move the switch from one position to another; switch correspondence logic, which vitally detects the position and mechanical locking of the switch; and logic, which is needed to drive traffic lights in the area of the switch.
  • switch logic control unit interfaces with a hydraulic control unit and the ATC system.
  • the switch logic control unit is located next to the hydraulic control unit .
  • the vital relays housed inside the switch logic control unit are the vital relays which are used to perform the vital checks. Also included in the unit are various circuit breakers, power transformers, and lightning arrestors which make up the control circuits.

  • the female member 60 essentially is a member that includes a hole passing therethrough and is adapted to receive the male member 58.
  • a limit switch 62 is provided on a rearward end of the female member 60.
  • the location of the lock pin 56 at approximately the centerline of the tracks 22, 24, 26, 28 and 30 provides not only lateral and vertical support, but also support to prohibit overturning. Additionally, at this location, the female members 60 utilize spherical bearings to aid in locating the tracks to overcome slight misalignments and to compensate for thermal loading and vehicle force distortions .

  • the intermediate stop pin 68 is a removable assembly. Therefore, if it is not needed, it can be removed.
  • Use of the stop pin 68 permits the use of a thinner guide track which decreases the cost of the structure. It also permits the use of a greater radius of curvature which decreases the length of the switch. Therefore, a variety of geometries can be achieved, and the vehicle can travel faster through curves.
  • a vehicle is traveling along the inbound track 22.
  • the guideway transfer switch 10 must be arranged so that the transfer curved track 30 aligns with respective ends of tracks 22 and 26.
  • the transfer straight track 28 will contact limit switches 38 and 40 which will send a signal to a control system (not shown) to indicate that the straight track 28 is in a proper position to avoid interference with the vehicle traveling along the guideway.
  • respective male members 58 are then activated so that they are urged into the female members 60 found at opposite ends of the curved track 30.
  • Limit switches 62 are then activated by an end of the male member 58.
  • a signal is sent to the control system indicating that the curved track 30 and tracks 22 and 26 are properly aligned and that the receiver 60 properly received the pin 58.

  • the lock pins are retracted and the trolley assemblies 32 and 34 are actuated by an electro-mechanical drive, causing the curved track 30 to move toward limit switches 42 and 44.
  • the respective male members 58 are then activated and are received at respective ends of the track 28 by female receiving members 60.
  • the ends of the respective male members contact limit switches 62 that send a signal that the straight track is properly aligned with tracks 22 and 24 and that the receiver 60 properly received the pin 58.
  • the intermediate stop 68 for the straight track 28 is activated. The above process is again reversed if curved track 30 is to be aligned with tracks 22 and 26.
  • the present invention provides a guideway transfer switch 10 that includes a plurality of tracks 28 and 30 extending in a substantially first direction and movably secured to transfer drives 32 and 34 for moving the tracks 28 and 30 in a substantial transverse direction with respect to the first direction.
  • the guideway transfer switch 10 can include more than two tracks. It should be evident that the present invention is much simpler and less expensive to install than if the switch pit 20 were moved by a transfer table which requires movement of the complete arrangement. In other words, only the tracks 28 and 30 need to be moved as opposed to a complete transfer table.
  • the present invention is substantially lighter than a transfer table, namely 7,000 pounds as opposed to 30,000 pounds. This results in a quicker cycling time, on the order of six seconds, and takes up less space than the prior art arrangements.
