Description

  The present invention is a vehicle in which one boarding vehicle and two lower driving carts are formed on a single-line rail laid on a concave and convex shape that undulates up and down in a side view and in a curved inclined surface meandering left and right in a plan view. Thus, the present invention relates to a two-vehicle traveling vehicle in which the boarding vehicle can always travel in a substantially horizontal state.

  2. Description of the Related Art Conventionally, there is a traveling vehicle (skew elevator) that travels on a linear rail laid on an inclined surface. For example, as shown in Patent Document 1, a passenger vehicle arranged on a carriage while linearly laying a rail on an inclined surface and running a carriage wheel along the rail always maintains a horizontal state. The passenger vehicle is swung on the carriage so that the absolute horizontal state can be maintained.

JP 2001-048009 A

  However, when the skew elevator is a large vehicle, the portion of the carriage that supports the passenger vehicle also becomes large, the load is concentrated, and the weight increases. In addition, the output of the drive motor and the speed reducer that drives the carriage part is increased, resulting in a problem that the weight of the entire carriage is increased. As a result, it is necessary to increase the structure of the rail or to increase the strength of the rail.

  Further, in recent inclined surface traveling vehicles, in order to lay straight rails on uneven inclined surfaces, a bridge support girder for rail support must be erected on a sloping ground over many lengths to support the rails. I must. For this reason, the rail laying work is complicated and structurally complicated, and various measures must be taken in terms of support strength, which is disadvantageous in terms of cost.

  In addition, by laying the rail in a bent shape in a plane, the support of the rail to the concave and convex inclined surface is made a simple support structure, thereby ensuring the support strength of the rail and simplifying the support structure. As a result, a two-wheel drive vehicle that is advantageous in terms of cost has appeared.

  However, since rails laid along such uneven slopes have many height differences in the rail as a whole, the front and rear lengths of the traveling vehicle can be used when the traveling vehicle is equipped with a large number of personnel and articles. When traveling on a rail with a large undulation, the distance between the front wheel and the rear wheel becomes longer, and the top of the rail swell So that the so-called prone phenomenon may occur, causing trouble in running, so it is necessary to reduce the swell angle of the rail along the concavo-convex slope and make it a nearly flat laying rail. The same problem as the defect in the support structure in which the linear rail is laid on the uneven slope has occurred.

  The present invention has been made to solve the above problems, and a large boarding vehicle travels on a rail laid on a curved inclined surface that undulates vertically in a side view and meanders left and right in a plan view. An object of the present invention is to provide a two-wheeled traveling vehicle.

  (1) Therefore, in the present invention, a substantially open U-shaped carriage that is configured to travel while straddling on a single rail is separated into a front carriage and a rear carriage. A drive shaft linked to the motor is installed on one side wall of the trolley, and a pinion provided at the front end of the drive shaft is engaged with a rack laid along a single-wire rail, so that the front and rear are connected via the rack and the pinion. The carriage is configured to travel along the single rail, and the passenger vehicle is mounted on the upper part of the front and rear carriages, and the carriage connection frame is disposed between the bottom frame of the passenger vehicle and the front and rear carriages. One end of the connection frame is pivotally supported by the bottom frame, and a cylinder is interposed between the middle of the carriage connection frame and the bottom frame of the passenger vehicle. Further, the front and rear parts of the carriage connection frame and the front and rear carriages And the top of We have respectively rotatably pivotally connected to provide a two carriage type traveling vehicle according to claim.

  (2) Further, in the present invention, in (1), any one of the front and rear carriages is configured to be swingable left and right relative to another carriage.

  According to the invention described in claim 1, since the carriage on which the passenger vehicle is mounted is divided into the front carriage and the rear carriage, a space portion can be formed between the front carriage and the rear carriage, The load on the carriage itself can be reduced as compared with the case where the entire vehicle is constituted by one. Further, by reducing the load, the rail structure on which the carriage is placed can be reduced in weight, and when the rail is already laid, the existing one can be used.

  In other words, a conventional rail, rack, column, etc. can be used by distributing the load of the drive unit and traveling wheels by using two lower drive trolleys for a vehicle twice as heavy as a conventional elevator. Thus, it is advantageous in terms of cost.

  Further, since the front carriage and the rear carriage are provided so as to be rotatable around a horizontal axis with respect to the carriage connection frame, smooth running on the uneven rail in a side view is possible. Furthermore, since it is provided so as to be rotatable around an axis in the vertical direction, smooth running on a rail laid on a curved inclined surface in a plan view is possible.

  According to the second aspect of the present invention, any one of the front and rear carriages is configured to be able to swing left and right relatively with respect to the other carriages. For example, it is uneven in a side view and curved in a plan view. Smooth running is possible even on the rails laid on the inclined surface.
