Description

  The present invention relates to a seat posture control device in a rail-type personnel-equipped vehicle that travels on a rail installed on the ground.

  In large-scale construction such as pipelines and bridges installed in the wilderness and forests away from the base camp, rail-type transport vehicles are used to transport various materials and personnel. There are many rail-type transporting vehicles that are installed on the ground with rails on the ground, and according to this, there is no need to strictly level the ground, and logging of surrounding trees etc. can be narrow, The advantage is that the installation cost is low. In general, the rails of a rail-type transport vehicle have many single rails, but when transporting large loads or long loads, a multiple rail composed of a main rail and a sub rail is used.

  Of these, transport vehicles that transport personnel require seats, but some have multiple seats to transport many personnel at once, and in such cases, seats are generally not used. It is installed in a column in the front-rear (traveling) direction. On the other hand, this type of rail has many undulations depending on the terrain laid, and is characterized by a large gradient. Therefore, if the posture of the seat is fixed, the body also tilts when undulating, so that the passenger feels uneasy and in some cases dangerous. For this reason, there is one that keeps the posture of the seat horizontal regardless of the inclination of the rail.

  An example is shown in Patent Document 1 below, but this prior example manually operates the posture change of the seat, which is complicated and imposes a burden on the passenger. For this reason, Japanese Patent Application Laid-Open No. H10-228707 proposes a vehicle in which a tilt sensor that detects the tilt of the rail (vehicle body) is attached to the transport vehicle, and the seat is automatically leveled by the output of the tilt sensor. However, in the preceding example, the seat is installed sideways so that the passenger feels uneasy, and the structure for leveling is complicated.

  The problem to be solved by the present invention is to automatically level the seat according to the inclination of the vehicle body, and to make this configuration simple and reliable and can be realized at low cost.

  Under the above-described problems, the present invention provides a rail-type personnel carrier having a seat installed in the front-rear direction and traveling on a rail erected on the ground as described in claim 1. A tilting frame that supports the standing seat frame so that it can be pivoted back and forth on a horizontal axis, and has a drive body that hangs the arm from the seat and pivots the arm back and forth. The present invention provides a posture control device for a seat in a rail-type personnel carrier characterized in that a driver is driven by the output of a sensor to make the seat horizontal.

  And in this, the structure described in claim 2 is provided with a plurality of seats in a column, the arm is provided in each seat, and each arm is rotated back and forth by the drive body, the drive body and the arm, As a specific configuration, the worm wheel is formed at the lower end of the arm according to claim 3, and the driving body is a worm that meshes with the worm wheel. Provides a configuration.

  According to the first aspect of the present invention, the posture of the seat can be achieved by only one driving body (and the driving source) by attaching the arm to the seat so that the seat can be tilted forward and backward, and the tilt sensor for detecting the tilt of the rail. Can be leveled automatically. According to the configuration of the second aspect, even if there are a plurality of seats, the same configuration is sufficient, and according to the means of the third aspect, a structure for rotating the seat can be simplified.

It is a side view of a transport vehicle. It is a partial side view of the seat part of a transport vehicle. It is a partial side view of the seat part of a transport vehicle.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a side view of a rail transport vehicle. The transport vehicle travels using a rail 2 installed on a ground as a guide 1 and includes a towing vehicle 3 and a carriage 4 on which a person is placed. In this example, two tow trucks 3 are used, and another truck 4 for loading luggage is also towed by a coupler 21. However, there may be only one tow truck 3 or for loading personnel. There may be only trolley 4. In this case, the rail 2 is constructed over a long range of unmanned areas such as forests, wildernesses, and deserts, and has a feature that there is a steep slope (front-rear inclination) or a curve in the middle.

  The towing vehicle 3 is supported by a wheel unit 5 having four wheels for holding the rail 2 from above and below, and travels on the rail 2 without falling down. Since the relationship between the wheel unit 5 and the rail 2 is publicly known, details are omitted here, but in short, a rack is attached to the rail 2. The towing vehicle 3 is equipped with an internal combustion engine 6 and a mission 7, and the output shaft of the mission 7 is connected to a drive wheel constituting one wheel of the wheel unit 5. The drive wheel is provided with a pinion, and travels with the pinion meshing with the rack.

  Therefore, it is a feature of this transport vehicle that it can run even on a steep slope. Note that if the slope of the rail 2 becomes steep, the posture of the engine 6 may be tilted and the operation thereof may be disturbed, so that the posture of the engine 6 can be kept horizontal. May incorporate devices. In this example, a control vehicle 8 having a seat on which a driver sits is connected to the rear of the rear towing vehicle 3, and a generator 9 is mounted on the control vehicle 8. The reason for installing the generator 9 will be described later. In addition, the control vehicle 8 may be omitted, and in this case, the generator 9 is mounted on the towing vehicle 3 or the cart 4.

  The carriage 4 has a chassis 11 supported by a wheel unit 10 that holds the rail 2 from above and below with four wheels. The control vehicle 9 is also supported on the rail 2 by the wheel unit 11. In addition, the two towing vehicles 3, the control vehicle 8, and the cart 4 are connected by a towing device 12 that can rotate back and forth and turn left and right.

  One (or more) of the carts 4 is provided with a seat 12 for carrying a person. A seat frame 13 is erected on the chassis 11, and the seat 12 can be rotated back and forth around a horizontal shaft 14 provided horizontally on the seat frame 13. In the case of this example, a plurality of seats 12 are arranged in a row in the front-rear direction (traveling direction) so that a large number of personnel can be mounted. In addition, although illustration is omitted, a plurality of seats 12 may be provided in a row (in the left-right direction, the width direction of the chassis 4). Also, there may be only one seat 12 for one person to sit on.

  An arm 15 hangs down from the lower surface of the seat 12, and in this example, a worm wheel 16 is formed at the lower end of the arm 15. On the other hand, on the chassis 11 below the arm 15, a driving body 18 in which a worm 17 that meshes with the worm wheel 16 is formed extends in the front-rear direction. The driving body 18 is driven by a motor 19 with a speed reducer mounted on the chassis 11, and its power source is taken from the generator 9 described above. Note that the worm 17 only needs to be formed on the portion of the worm wheel 16 concerned, and the worm 17 receives a reaction force downward and a thrust in the front and rear, and is appropriately received by the bearing 20.

  As described above, when the driving body 18 is rotated by the motor 19 with a speed reducer, the worm 17 rotates the worm wheel 16 to tilt the arm 15, that is, the seat 12 back and forth. As in this example, the worm wheel 16 and the worm 17 are preferably used to tilt the seat 12 back and forth because the reaction force from the seat 12 can be cut off. In addition, although illustration is abbreviate | omitted, the arm 15 and the drive body 18 may be comprised with a screw and nut mechanism, and the drive body 18 may be pushed back and forth. Furthermore, the arm 15 may be connected by a rope, and the rope may be pushed back and forth with a winch or the like provided at the front and rear.

  Such posture control of the seat 12 is automatically performed by detecting an inclination angle by an inclination sensor (not shown). Various types of tilt sensors, such as a pendulum type and a liquid level type, are commercially available, all of which are characterized by generating electrical signals according to the direction and angle of inclination. Therefore, this inclination sensor is attached to the chassis 11 and the motor 19 with a speed reducer is activated by the output. That is, the seat 12 can be corrected horizontally by tilting the seat 12 forward when tilting up and tilting backward when tilting down.
