Description

  The present invention relates to a side forklift vehicle that lifts a vehicle on a road from a side, places the vehicle on a loading platform, and transports the vehicle, and a method for loading the vehicle.

  As a vehicle for carrying an automobile, there is a so-called carrier car.

  When loading and unloading a car in a carrier car, a road plate is set on the rear side of the carrier car so that the car can enter or get off the deck by self-propelled.

  On the other hand, when transporting an automobile that cannot run on its own, there is a so-called tow truck. For example, the front wheel of a vehicle in violation of parking is lifted and the rear wheel is grounded so as to be rotatable, or the front and rear wheels are placed on auxiliary wheels for transport.

  By the way, in recent years, the number of automobiles that are illegally discarded is increasing because the disposal procedure of automobiles has become a fee.

  In many cases, these are not capable of self-propelling, and are also difficult to idle. In particular, in the case of a four-wheel drive vehicle, even if the wheels are idled, the power transmission system is In many cases, it cannot be moved in an idle state because it is damaged, and the tire may be punctured.

  Furthermore, many of the abandoned cars are often left on riverbanks and mountain roads, so that the scaffolding is poor and it is often difficult to attach the auxiliary wheels for moving the tow truck with a tow truck.

  On the other hand, as disclosed in Patent Document 1 and Patent Document 2, it is conceivable to mount a forklift truck on the truck bed, but a space for the forklift truck is required, and the passenger car can be lifted. Large forklift trucks have a problem in that there is no space for loading platforms on which passenger cars can be placed.

That is, the vehicle width direction positions of the right wheels M1R and M2R and the left wheels M1L and M2L are adjusted so as to overlap the base end and tip end wheel receivers 17A and 17B, and then the fork post front and rear slide cylinders 19A and 19B The front fork arm 16 is slid into the front side of the front wheels M1R and M1L of the vehicle M, and the rear fork arm 18 is slid into the rear side of the rear wheels M2R and M2L of the vehicle M (see FIGS. 10 and 11). ).

  In step 111, as shown in FIG. 12, the front ends of the front and rear fork arms 16 and 18 are connected by a fork front end connecting bar 21 so that the front ends are not opened.

  In step 112, the front and rear short arms 40, 42 are rotated 90 degrees from the standby position in the vehicle longitudinal direction shown in FIG. 11 to the position in the vehicle width direction shown in FIG. Thus, the front and rear fork arms 16 and 18 are parallel to each other.

  In step 113, the front and rear short arms 40 and 42 are driven by the short fork slide cylinder 46 in the direction of the front fork arm 16 and the direction of the rear fork arm 18, respectively, and as shown in FIG. The lower part of the right front wheel M1R is sandwiched between the front fork arm 16 and the front short arm 40, and in step 114, the lower part of the right rear wheel M2R of the automobile M is interposed between the rear fork arm 18 and the rear short arm 42. Pinch.

  In this state, in step 115, the fork elevating cylinder 34 is slightly extended to slightly raise the side fork 14, the side short fork 44, and the automobile M mounted thereon together with the support frame 20.

  In step 116, it is determined whether or not the front and rear fork arms 16 and 18 are inclined toward the front end, for example, about 5 degrees.

  If Yes, the process proceeds to the next step 117, the tilt of the front and rear fork arms 16, 18 is corrected by the tilt cylinder 32, and the process proceeds to step 118. If No, the process proceeds to step 118.

  In step 118, the vehicle M is raised to a level slightly higher than the loading platform 12 together with the front and rear fork arms 16, 18 and the front and rear short arms 40, 42 (see FIG. 14).

  In step 119, the roller chain 36 is driven by the oil motor 37, and the fork posts 16A and 18A and the support frame 20 are moved through the post base 23 in the fork base end direction (right end direction in FIG. 3).

  When the rear end side fork post roller 38B of the post base 23 reaches the right end as shown in FIG. 3, the tilt cylinder 32 is extended in step 120, and the rear end side fork post roller of the post base 23 is extended. 38B is pushed down from the position of FIG. 3 to the position of FIG. At this time, the rotating arm 54 is swung clockwise in FIG. 3 by the rotating arm cylinder 56 immediately before, and the sprocket wheel 51 is pulled to the position of FIG.

  By the lowering of the rear end side fork post roller 38B to the standby position, the front end side fork post roller 38A further moves in the proximal direction to the position shown in FIG. 4, and accordingly, the front and rear main posts 24, 26 is also moved to a position in the proximal direction until FIG.

  In step 121, the fork elevating cylinder 34 is extended, and the side fork 14 and the side short fork 44 are lowered onto the fork receiving frame 12A.

  In step 122, the wheels and front and rear fork arms 16 and 18 of the automobile M are fixed on the loading platform 12 by the tire / fork fixing device 80.

  In step 123, the outrigger 58 is pulled up so that the side forklift vehicle 10 can travel.

  Thereby, the loading of the automobile M on the side forklift truck 10 is completed.

  In the above embodiment, even when the automobile M is not loaded, heavy members such as the support frame 20, the front and rear main posts 24 and 26, and the fork posts 16A and 18A are shown in FIG. Since the side forklift vehicle 10 is biased to the right side in the vehicle body width direction, the center of gravity is located on the right side in the vehicle body width direction compared to the case where the side fork 14 and the support frame 20 are not provided. Compared to this, the left side of the loading platform 12 is not heavy, and becomes an unstable element when the side forklift truck 10 is traveling with an empty load.

  On the other hand, if the front main post 24 and the rear main post 26 are in a standby state on the center side of the loading platform 12 from the position shown in FIG. 4, the center of gravity returns to the center side in the vehicle body width direction. Running in an empty state is stable. For this purpose, for example, if the difference in expansion and contraction of the front end wheel receiver 17B in the front and rear fork arms 16 and 18 is increased and the distance from the base end side wheel receiver 17A during standby is shortened, the corresponding amount is increased. Only the center of gravity can be shifted to the center side.

  Furthermore, in the said Example, although the side fork 14 is comprised from a pair of front and back L-shaped members, it is not limited to L shape, You may comprise only a front side and a rear side fork arm. .

  In the above embodiment, the wheel of the automobile M is positioned and loaded by the side fork 14 and the side short fork 44, but the present invention is not limited to this. If the support of the automobile M by the side fork 14 is sufficient, it may not be provided.

  However, when the side short fork 44 is provided, it is possible to reliably suppress the wheels of the automobile M from getting over the side fork 14 by acceleration / deceleration when the side forklift truck 10 loaded with the automobile M is traveling.
