As shown in FIG. 4, when the pair of movable levers 22 are at the positions shown by solid lines, the two connecting bolts 37 and the one rotating arm 36 are aligned on the same straight line. Therefore, the rotational force applied to each movable lever 22 is suspended by the compressive stress of the connection bolt 37 and the like, and the rotational force applied to the worm wheel 31 and the like is minimized. If a horizontal load applied to the movable lever 22 from the wheel 72 remains as a bending load of the connection bolt 37 or the like, a force for rotating the worm wheel 31 remains, and a strong link mechanism must be provided. By configuring as in the example, the strength of the members can be reduced and the vehicle moving device can be reduced in weight and size. When the wheels 72 of the automobile 71 are lifted, FIG.
The front wheel 10 is driven by the motor 11 by operating the speed adjustment lever 16 shown in FIG. 10, and the front wheel 10 is steered by bending the rudder rod 13 left and right to move the automobile 71 as shown in FIG. 10B. As shown by an imaginary line in FIG. 1, the connecting rod 3 is moved relative to the towing vehicle 1 in any direction by θ = 45.
The car 71
By turning the front wheel of the vehicle at 45 ° to make a small turn, the vehicle 7 can be turned without moving the vehicle 71 forward and backward.
The head swing operation of moving only one head becomes possible.
As shown in FIG. 2, the car 71 can be moved to a very narrow place, and the car 71 can be moved to a narrow place where even a door cannot be opened and a person cannot enter or exit the car. The rudder rod 13 can be tilted until it is horizontal.
Since the bogie main body 20 of the towed vehicle 2 is raised when the car 71 is moved, a sufficient space is formed between the bogie main body 20 and the floor surface, and some unevenness is formed on the floor surface. You can run without any problems. When the movement of the car 71 is completed, the first and second elevating means 23a and 23b are operated to lower the car 71 together with the bogie main body 20. Next, as described above, the motor 32 is driven to rotate the pair of movable levers 22 by 90 ° to the position indicated by the phantom line in FIG.
From below. When the moving operation of the automobile 71 is completely completed, a pair of fixed levers 2 as shown by phantom lines in FIG.
1 is bent upward to reduce the space occupied by the vehicle moving device. Since the overall length of the vehicle moving device according to the present invention is short, the elevator car can be short even when mounted on an elevator. The operation of raising and lowering the towed vehicle 2 as well as driving the towed vehicle 1 can be performed by the operation unit 14 at hand. In this embodiment, since a movement requiring a large force is performed by the driving means, a large amount of labor is not required. No maintenance is required. In this embodiment, the towing vehicle is a self-propelled type having a driving motor. However, the towing vehicle may be manually driven without a motor. In the embodiment, a motor is used as a drive source of the movable lever and the lifting / lowering means, but a hydraulic cylinder, a hydraulic jack, or the like may be used. In this embodiment, the movable lever is rotatable. However, a configuration in which the movable lever projects from the bogie main body using a ball screw mechanism or a cylinder may be employed. Further, in this embodiment, the means for changing the position of the fixed lever is shown as a manual structure. However, the feed screw is changed to a ball screw mechanism to be driven by a motor, or the fixed lever is directly used by using a cylinder. It may be driven. Further, in the present embodiment, the first and second lifting means are provided as the lifting means, but it is sufficient if at least the wheels of the automobile are floating.
Only the first elevating means is sufficient. Still further, the first and second elevating means may be linked to elevate and lower the bogie main body. Further, the fixed lever and the movable lever have a double cylinder structure so that the total length from the tip of one fixed lever to the tip of the other fixed lever can be changed. It can be made to correspond to. As can be seen from the above description, claim 1
According to the vehicle moving device according to the present invention, the vehicle is composed of a relatively rotatable towing vehicle and a towed vehicle, and a part of the vehicle is mounted on the towed vehicle and moved, so that it is possible to make a small turn and in a narrow place. Cars are easy to move. In addition, the left and right wheels are lifted by a pair of fixed levers and movable levers, which lifts a part of the car, so that the vehicle moving device does not contact the vehicle body and it is possible to move even cars without hooks and bumpers This is particularly suitable for use in moving a new vehicle. Further, the towed vehicle is lifted by the bogie main body by the elevating means, so that the towed vehicle can be moved without trouble even on a floor surface having large unevenness. In addition, since the towed vehicle is put under the car, the truck body of the towed vehicle is lifted, and then the towed car is operated only by operating the towed vehicle, so that only one worker must move the car.
