It is configured not to be transmitted to the travel drive device 2 of the carriage body 3.

  Next, the operation of the above embodiment will be described.

  When transporting the vehicle 1, first, as shown in FIG. 5A, the truck body 3 is positioned at the rear of the vehicle 1, and the lift bar 4b of the lifter 4 is rotated to the storage position. Move the body 3 forward.

  Subsequently, as shown in FIG. 5 (b), the carriage main body 3 is advanced to a position where the pulley 52 at the front end of the belt conveyor 50B contacts the rear wheel 1b of the vehicle 1 via the belt 53 and is temporarily stopped.

  With the carriage main body 3 stopped, as shown in FIG. 5C, the lift bar 4b of the lifter 4 is pivoted to the unfolded position, and the rear wheel 1b of the vehicle 1 is moved with the lift bar 4b and the belt conveyor 50B. And lift it up while supporting it from the front and back with the pulley 52 of the

  From this state, as shown in FIG. 5D, the carriage main body 3 is advanced while driving the belt conveyor 50B, and the sliding speed of the belt 53 of the belt conveyor 50B is synchronized with the traveling speed of the carriage main body 3. While sliding the rear wheel 1b of the vehicle 1 lifted up by the lifter 4 to the rear side of the truck main body 3, the truck main body 3 is made to approach the lower part of the vehicle 1.

  At this time, as shown in FIG. 6 (e), the lift bar 4b is once returned to the storage position.

  After the lift bar 4b is once returned to the storage position, as shown in FIG. 6 (f), the carriage body 3 is further advanced, and the pulley 52 at the front end of the belt conveyor 50B is attached to the front wheel 1a of the vehicle 1 via the belt 53. The carriage body 3 is advanced to a contact position and temporarily stopped.

  In the state where the carriage main body 3 is stopped, as shown in FIG. 6 (g), the lift bar 4b of the lifter 4 is again rotated to the unfolded position, and the front wheel 1a of the vehicle 1 is moved with the lift bar 4b and the belt conveyor 50B. And lift it up while supporting it from the front and back with the pulley 52 of the

  After that, with the rear wheel 1b of the vehicle 1 placed on the belt conveyor 50B and the front wheel 1a of the vehicle 1 lifted up by the lifter 4, the truck body 3 is made to travel and the vehicle 1 is moved. Transport

  Incidentally, after temporarily returning the direction of the traveling wheels 2b of the two traveling units 2A of the traveling drive device 2 to a preset origin (for example, the direction shown in FIG. 1), the two traveling drive devices 2 The direction of the traveling wheel 2b is turned to the right by rotationally driving the turning frame 2a of the traveling unit 2A in the direction of right rotation (right turn) to change the phase by 90 ° from the direction shown in FIG. When the traveling wheel 2b is rotationally driven in the forward direction, the vehicle 1 can be transported in the forward direction, and when the traveling wheel 2b is reversely rotated, the vehicle 1 can be transported in the backward direction. .

  As described above, the direction of the traveling wheel 2b is set by rotating the turning frame 2a of the two traveling units 2A of the traveling drive device 2 in the direction of turning left (turning left) from the state of moving the vehicle 1 forward or backward. If the traveling wheel 2b is rotationally driven in the forward direction, for example, in the direction of 45.degree. Left, it becomes possible to transport the vehicle 1 in the direction to advance diagonally forward left, and reverse rotation of the traveling wheel 2b. If this is done, it becomes possible to transport the vehicle 1 in the direction to make it go backward and diagonally to the right.

  On the other hand, after temporarily returning the direction of the traveling wheels 2b of the two traveling units 2A of the traveling drive device 2 to a preset origin (for example, the direction shown in FIG. 1), the two traveling drive devices 2 By rotationally driving the traveling wheels 2b of the traveling unit 2A in the same direction, it is possible to traverse the truck body 3 on which the vehicle 1 is mounted in the left direction. Further, by driving the traveling wheels 2b of the two traveling units 2A of the traveling drive device 2 to rotate in the same direction opposite to the time of traversing left, the bogie main body 3 on which the vehicle 1 is mounted is It is possible to traverse in the right direction.

  Furthermore, after temporarily returning the direction of the traveling wheels 2b of the two traveling units 2A of the traveling drive device 2 to a preset origin (for example, the direction shown in FIG. 1), the two traveling drive devices 2 By rotating the traveling wheels 2b of the traveling unit 2A in mutually opposite directions, the bogie main body 3 on which the vehicle 1 is mounted is turned left (turned left) at that position, and the direction of the vehicle 1 can be changed. It becomes possible. Further, by driving the traveling wheels 2b of the two traveling units 2A of the traveling drive device 2 to rotate in opposite directions opposite to the time of left rotation, the bogie main body 3 on which the vehicle 1 is mounted is It is possible to change the direction of the vehicle 1 by turning right (turn right) at the position.

  Then, after the bogie main body 3 on which the vehicle 1 is mounted is moved to a predetermined position to be conveyed, and the direction of the vehicle 1 is changed as necessary, the lift bar 4b of the lifter 4 is pivoted to the storage position The front wheel 1a of the vehicle 1 is lowered to the ground from the state where it has been lifted. Subsequently, when the carriage main body 3 is moved backward at a synchronized speed while driving the belt conveyor 50B in the opposite direction to the mounting direction of the vehicle 1 described above, the carriage main body 3 is pulled out from the lower part of the vehicle 1, The rear wheel 1 b of 1 can be lowered to the ground, and the transportation of the vehicle 1 is completed.

  In the above-mentioned example, although the case where the truck body 3 is made to approach from the rear of the vehicle 1 has been described, it goes without saying that the vehicle 1 can be similarly transported even when the truck body 3 is made to approach from the front of the vehicle 1 Yes.

  If the upper surface of the bogie frame 3a of the bogie main body 3 contacts the lower face of the vehicle 1, it is detected that the tape switch 25 is turned on and the bogie frame 3a interferes with the vehicle 1.

  The distance between the control device 8 mounted on the rear of the dolly frame 3a of the dolly main body 3 and the vehicle 1 is measured by the ultrasonic sensor 26, and the distance between the control device 8 and the vehicle 1 is less than the set value. When this happens, an alarm is issued and contact between the control device 8 and the vehicle 1 is avoided.

  Furthermore, since the contact detector 58 such as a bumper switch extending in the front-rear direction of the carriage main body 3 is attached between the front end portions of the support shafts 56, 57 of the pulleys 51, 52 of the belt conveyor 50B, When the main body 3 comes into contact with an obstacle or the like, it is detected by the contact detector 58, and a response such as a change in the course is taken.

  As a result, in this embodiment, unlike the vehicle conveyance device disclosed in Patent Document 2, even when the minimum ground height of the vehicle 1 is low, when the bogie main body 3 is made to approach the lower part of the vehicle 1, It is avoided that the trolley | bogie main body 3 contacts the vehicle 1 lower part, and conveyance of the vehicle 1 can be performed smoothly.

  Further, in the present embodiment, the rear wheel 1b (or the front wheel 1a) of the vehicle 1 is mounted on the conveyor 50 provided in the bogie main body 3, so that it is also possible to transport the vehicle 1 with different wheel bases. It becomes possible.

  Furthermore, the point that the lift bar 4b is pivoted and expanded so as to project laterally is the same as the vehicle conveyance device disclosed in Patent Document 2, but in this embodiment, the belt conveyor 50B is Since a contact detector 58 such as a bumper switch extending in the front-rear direction of the bogie main body can be attached between the tip portions of the support shafts 56, 57 of the pulleys 51, 52, a bracket or the like longer than the lift bar 4b You do not have to project from the side.

  On the other hand, in the present embodiment, unlike the vehicle conveyance device disclosed in Patent Document 3, no special device such as a tire stopper is necessary apart from the device itself, and the restriction on the conveyance location of the vehicle 1 is eliminated.

  Thus, it is possible to cope with the transportation of a wide range of vehicle types 1 without being restricted by the minimum ground clearance of the vehicle 1 and the wheel base, and the attachment of the contact detector 58 can be easily performed, and like a tire stopper. It is possible to carry the vehicle 1 without the need for special equipment.

  The vehicle conveyance device of the present invention is not limited to the above-described embodiment, and various changes can of course be made without departing from the scope of the present invention.
