Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of Invention] (Field of Industrial Use) The present invention relates to a vehicle carrying deck which is attached to a truck or a trailer and is used for carrying a vehicle.

(Prior Art) Generally, a vehicle transport deck is designed to load a large number of vehicles, and is attached to the rear of a truck or a trailer to transport the vehicles. At the time of loading, a road board called a boarding board is placed between the deck and the ground, and when the vehicle is finished loading, the road board is removed and stored at a predetermined place.

To attach the road plate, it is necessary to match the width of the wheels of the vehicle on which the road plate is to be loaded, and to remove the road plate, the road plate must be carried to a predetermined location. The work efficiency of loading is poor and there is a problem in ensuring safety.

Therefore, for example, Japanese Unexamined Patent Publication (Kokai) No. 60-244638 discloses a vehicle carrying deck in which the rear deck of the lower deck is formed so as to be swingable to serve as a rotary grounding plate to solve the above problems.

As shown in FIG. 11, the vehicle carrying deck is mounted on a rear end portion of a lower deck 101 of a trailer 100 via a hinge device 102, 102 so that a rotary ground plate 103 is swingably mounted. It is configured to be moved by a cylinder device 104 provided on the trailer 100.

(Problems to be solved by the invention) In a vehicle transport deck in which a rotating ground plate is provided swingably behind the lower deck, the rear overhang cannot be so large due to the tire allowable load of the trailer, etc. There is a limit to the size, so when the deck is tilted,
As shown in FIGS. 12 and 13, the angle of intersection with the ground becomes large, and when the low-floor vehicle 105 is boarded, the lower surface of the vehicle 15 may interfere with the deck and the ground.
Also, since the tilting state of the rotating deck is the same when the lower deck is in the upper deck and when it is in the upper deck, the upper deck 106 must come down to the upper surface of the rotating deck 103 as shown in FIG.
Because the upper deck can not be entered and the vehicle running surface of the upper deck 106 is lower than that of a tire house such as a trailer,
It is difficult to mount a vehicle wider than the tire house on the upper deck.

The present invention has been made in view of the above-mentioned points. By moving the rotation fulcrum in the front-back direction of the outer frame, the intersection angle with the ground can be set small, and the upper deck can be lowered to the inclination angle of the rotating deck. An object of the present invention is to provide a vehicle carrying deck that facilitates mounting of a wide vehicle because it is not necessary.

[Constitution of device]

(Means for Solving the Problems) In a vehicle carrying deck of the present invention, an outer frame is pivotally attached to a rear loading platform of a lower deck so as to be swingable in the vertical direction, and is slidable in the front-back direction in the outer frame. A road board deck is provided so as to be swingable in the vertical direction, and a device for moving the road board deck in the front-rear direction and a device for moving the road board deck in the vertical direction are provided.

(Operation) In the vehicle transport deck of the present invention, the pivot fulcrum of the road board deck is moved in the front-back direction by sliding the road board deck in the outer frame in the front-back direction. The angle of intersection with the ground is set small so that the lower surface of the vehicle when riding a low-floor vehicle does not interfere with the deck and the ground, and the slope of the road board deck is set to the rear when riding a vehicle on the upper deck. Therefore, it is not necessary to lower the upper deck to the inclination angle of the road board deck, and it is easy to mount a wide vehicle because the running surface of the vehicle is above the tire house.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes an outer frame of a vehicle carrying deck, and a base end side of the outer frame 1 is attached to a trailer rear lower vehicle frame 3 via a rotating device 2 so as to be vertically movable. A channel 1a having a U-shaped cross section extending in the longitudinal direction of the outer frame 1
The inner frame 4 is attached to the telescope in a telescopic manner. In order to smoothly slide the inner frame 4 with respect to the outer frame 1,
A resin plate 5 is fixed to the upper and lower inner surfaces of the channel 1a as shown in FIG. The inner frame 4 is set to move in the front-rear direction (direction of arrow A) by cylinder devices 6, 6 (FIG. 3) having one end side pivotally attached to the outer frame 1 and the other end side pivotally attached to the inner frame 4. . An actuating device 9 including a slide tube 7 and a cylinder device 8 is arranged on both sides of the trailer rear lower vehicle frame 3. The roller 10 provided at the lower end of the slide tube 7 is attached to the channel 4a extending in the longitudinal direction of the inner frame 4 as shown in FIG.
A guide member is provided on the base end side of the inner frame 4 via a pin 11.
Twelve are pivotally attached. The guide member 12 is slidably attached to the channel 1a of the outer frame 1.

That is, the inner frame 4 moves longitudinally along the channel 1a of the outer frame 1 and the actuating device 9 causes the pin 10 of the guide member 11 to move.
Move up and down with the fulcrum as a fulcrum.

The inner frame 4 has a stopper 13, and the trailer rear lower vehicle frame 3 has stoppers 14 and 15 for the stopper 13 and the outer frame 1.
The upper limit stopper 16 for is arranged.

 Next, the operation will be described.

In order to enter the upper deck, the cylinder device 8 of the operating device 9 is actuated in the retracted state shown in FIG. 2 in the retracted state so that the outer frame 1 is brought into contact with the upper limit stopper 16. By moving, the stopper 13 of the inner frame 4 is disengaged from the disengagement stopper 14 provided on the trailer rear lower-stage vehicle frame 3. Then, by operating the cylinder device 6 in the extending direction, the inner frame 4 is guided along the channel 1a of the outer frame 1.
