Description

[Detailed Description of the Invention] The present invention relates to a cargo handling device with a truck for a freight vehicle.

Conventionally, a tailgate lifter is attached to the rear of a freight vehicle's loading platform so that it can rotate and be raised and lowered in a horizontal position, and is also used for loading and unloading cargo. Since the cargo was only used to load and unload the cargo, transport vehicles such as trolleys had to be used to transport the cargo between the cargo vehicle loading and unloading the cargo and the storage area where the cargo was stored. However, the transshipment work was troublesome. For this reason, it is conceivable to place the trolley and other cargo on the tailgate lifter and move it up and down. However, in this case, if the cargo is heavy or the tailgate lifter is tilted, the trolley will move up and down the tailgate. There was a risk of falling from the gate lifter, which was not favorable for work.

Therefore, a device has been devised in which the tailgate lifter is detachable from the lifting device so that the tailgate lifter can also be used as a trolley. There were problems such as it being difficult to attach and detach, or the attachment and detachment work was troublesome.

Therefore, the present invention was devised in view of the above-mentioned conventional problems, and it is easy to attach and detach, and moreover, even if the position of the truck part and the tailgate lifter body is slightly misaligned, it is possible to securely move the truck part to the tailgate lifter. It is an object of the present invention to provide a cart-equipped cargo handling device that can be attached to a lifter main body.

To this end, in the present invention, the cart-equipped cargo handling device has a part of the tailgate lifter cut out to form a removable truck part, and a channel-shaped support member is fixed near the outer periphery of the lower surface of the truck part. The outer circumferential surface of the support member on three sides except for the rear side part is tapered so that the lower end is located inside the upper end, and further, removable casters are provided on the lower surface of the support member near the four corners of the truck part. At the same time as attaching the tailgate lifter to the lower surface of the tailgate lifter body,
The intended purpose is achieved by fixing and configuring a channel-shaped support member having a taper that connects with the tapered portion of the support member.

The present invention will be described below with reference to illustrative embodiments.

Reference numeral a denotes a tailgate lifter which is attached to the rear of the loading platform A of a freight vehicle by means of an arm 11 and a power unit 12 so as to be rotatable and capable of being raised and lowered in a horizontal state. It is cut out in a substantially U-shape so that it opens upward (when used as a tailgate), and the cutout part serves as a removable truck part 13, and the other part serves as the tailgate lifter body 14 for the arm. It is pivotally attached to the tip of 11.

A channel-shaped support member 15 is fixed near the outer peripheral edge of the lower surface of the truck portion 13, and the outer peripheral surfaces 15a on three sides except for the rear side of the support member 15 are arranged such that the lower end is located inside the upper end. is tapered. Furthermore, removable casters 16 are attached to the lower surface 15b of the support member 15 near the four corners of the truck portion 13. Reference numeral 17 denotes a reinforcing member attached to the lower surface of the truck portion 13.

A channel-shaped support member 18 is fixed to the periphery of the lower surface of the tailgate lifter main body 14, and a channel-shaped support member 18 is fixed at a position of the support member 18 corresponding to the support member 15, that is, at the periphery of the notch on the lower surface of the tailgate lifter main body 14. Fixed support member 1
The inner circumferential surface 18a of the support member 15 is tapered such that its lower end is inclined inward so as to join with the taper of the outer circumferential surface 15a of the support member 15. 19 is a reinforcing member attached to the lower surface of the tailgate lifter main body 14.

Further, lock pins 20 and 21 are slidably attached to the center of the front end of the lower surface of the truck section 13 and to the rear of both sides of the lower surface of the tailgate lifter main body 14, respectively, and the tip of the lock pin 20 attached to the truck section 13 side is The support member 18 is fixed to the side edge of the front notch of the tailgate lifter main body 14, and the tailgate lifter main body 1
The tip of the lock pin 21 attached to the 4 side is configured to penetrate through the support member 15 fixed to both side edges of the truck part 13, and each lock pin 20, 21 is inserted into the lock pin 20, 21. The springs 22 and 23 installed in the lock are biased in the locking direction.

Next, the cargo handling operation using the tailgate lifter a will be explained.

First, when the tailgate lifter a is in a vertical position, pull the lock pin 20 to release the lock, and after setting the tailgate lifter a in a horizontal position, raise and lower the tailgate lifter a to load and unload cargo. Let's do it. At this time, when the caster 16 touches the road surface 24 as shown in FIG.
1a to the side edge of the tailgate lifter main body 14 and release the lock. (Refer to Fig. 3) This releases the truck portion 13 from the locked state, and at this point the tailgate body 14 can be rotated (oscillated).
When the lower surface of the tailgate lifter main body 14 is brought into contact with the road surface 24, the truck portion 13 is removed from the tailgate lifter main body 14. (See Figures 5B and 6) The locking pin 21 may be removed during cargo handling work, but in consideration of operational safety, it must be locked until the caster 16 is in contact with the ground. It is preferable to leave it there. Furthermore, by removing the caster 16, the entire tailgate lifter a can be used in the same manner as before, as shown in FIG.

As described above, according to the present invention, a part of the tailgate lifter is cut out to form a dolly, and the dolly can be attached by simply swinging the tailgate lifter body with the casters of the dolly in contact with the road surface. Since it can be attached and detached, the operation can be easily performed.

Further, according to the present invention, since the taper of the outer circumferential surface of the support member of the truck section is configured to rest on the taper of the inner circumferential surface of the support member of the tailgate lifter main body, when the truck section is attached, the Even if the part is slightly misaligned back and forth, left or right, it can be guided by the support member of the tailgate lifter body and automatically adjust its position, allowing it to be reliably attached to the tailgate lifter body.

Furthermore, according to the present invention, the casters are removable, so by removing the casters, the tailgate lifter can not only be used in the same way as before, but also improve its appearance when used as a tailgate. It has the following effects:
