Description

[Detailed description of the invention] The present invention is a loading platform roof opening/closing lift that can open and close the loading platform roof so that cargo can be loaded and unloaded from both sides as well as the rear of the loading platform, and which can lift the roof support point at the rear of the loading platform. Regarding type lorries.

Generally, a cover such as a hood is attached to the loading platform of a freight vehicle to prevent the cargo from being affected by direct sunlight, wind and rain, or to prevent the cargo from collapsing due to vibrations, shocks, etc. when the vehicle is running. In addition, for cargoes for which waterproofing is important, a box-shaped vehicle body is installed as a cargo platform.
By the way, in these cases, the loading and unloading port for cargo is only at the rear, which reduces the efficiency of cargo handling operations.

Therefore, for the purpose of saving labor, streamlining, and speeding up cargo handling operations, cargo vehicles with retractable cargo roofs are used, which allow cargo to be loaded and unloaded from both sides of the cargo platform. It is becoming more and more common. In this case, of course, a double door or the like is provided at the rear of the loading platform to allow cargo handling from the rear.

By the way, a freight vehicle with an opening/closing loading platform roof has a structure in which the roof is pivoted to a supporting member at the center of the upper part of the loading platform, and the opening/closing mechanism for opening and closing the roof is attached to the upper sides of the front frame and rear frame at the front and back of the loading platform. However, when handling cargo from the rear of the loading platform using a forklift, etc., the vertical width of the upper side of the rear frame is large due to the installation of the opening/closing mechanism, which means that the frontage is lowered, Loading and unloading from the rear is more inconvenient than with a normal box-shaped vehicle body. In particular, when loading tall cargo, the low frontage of the rear frame hinders cargo handling.

In view of the above-mentioned points, the present invention has been developed such that the upper side of the rear frame,
The rear part of the support member and the rear part of the roof are designed to be able to be lifted, making it easier to unload tall cargo from the rear of the loading platform, which in turn makes it possible to load the maximum amount of cargo onto the loading platform, improving transport efficiency. The purpose is to provide a lift-type freight vehicle with an opening/closing loading platform roof.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a cargo vehicle with an opening/closing lift type truck roof according to the present invention will be described with reference to the drawings.

1 to 4, the loading platform 1 of a truck includes a floor 2, a front frame 3, a rear frame 4, a support member 5 supported and connected at the center of the upper side of both frames, and a support member 5 on both sides of the support member 5. It is composed of a roof 6, a side fan 7, etc., each of which is pivoted so as to be openable and closable.

The front frame 3 and the rear frame 4 each have an upper side 3
The support member 5 is provided between the center portions of the upper side portions 3A and 4A. The upper side 3A of the front frame 3 is pivotally connected via a hinge 8 to the main body 3B of the front frame 3 standing upright on the floor 2, and is rotatable (tiltable) with respect to the main body 3B. There is. On the other hand, lift rods 10 are connected to the lower surfaces of both ends of the upper side 4A of the rear frame 4 via lift links 9, and as shown in FIG. The lift rod 10 is supported by a frame 11 so as to be slidable up and down, and the lower end of the lift rod 10 is connected to a hydraulic cylinder 12 fixed within the main body 4B.
The piston rod 13 is connected to the piston rod 13 of the piston rod 13.

The roof 6 has a substantially L-shaped cross section that covers the top and side surfaces of the loading platform 1, and is pivoted to the supporting member 5 symmetrically. The front frame 3 and the rear frame 4 are driven to open and close by opening and closing mechanisms provided in the upper sides 3A and 4A.

FIG. 3 shows an example of an opening/closing mechanism provided on the upper sides 3A, 4A. In this figure, the upper side 3
A tilt arm bracket 20 is fixed to the substantially central portion of the bottom surface of each of A and 4A, and a tilt arm 21 is pivotally connected to the bracket 20 by a pin 22. A roof tilt bracket 23 is fixed to the roof 6, and the tip of the tilt arm 21 is connected to the roof tilt bracket 23 by an adjuster stop rod 24 whose length is freely adjustable. Further, a cylinder bracket 25 is fixed to substantially the bottom side end portions of the upper sides 3A, 4A, and a double-acting hydraulic cylinder 26 is connected between the cylinder bracket 25 and a midway position of the tilt arm 21.

In the above configuration, if hydraulic pressure is supplied from the power unit to the hydraulic cylinder 12 and the double-acting hydraulic cylinder 26, the front frame 3 is moved as shown by the dashed line in FIG.
The upper side 4A of the rear frame 4 uses the side hinge 8 as a fulcrum.
The support member 5 and the rear side of the roof 6 are lifted, and the extension of the piston rod of the hydraulic cylinder 26 brings the roof 6 into an open state. In this state, cargo 30A having a height corresponding to the height H from the floor of loading platform 1 to the lower surface of support member 5 (indoor effective height) can be efficiently loaded and unloaded using forklift 30 or the like. Furthermore, it becomes easy to load cargo to the maximum extent by stacking it in multiple stages.

When a freight vehicle is traveling, both hydraulic cylinders 12,
26 is retracted, the upper side 4A of the rear frame 4 is lowered onto the main body 4B as shown by the solid line in FIG. can be protected.

Although not shown in the drawings, the main body portion 4B of the rear frame 4 erected on the floor 2 is provided with double-sided doors, single-opening doors, etc., which can be opened and closed freely.

As explained above, according to the present invention, a supporting member is supported and connected to the center of the upper side of the front frame and rear frame of the loading platform, and a cross section covering the top and side surfaces of the loading platform is provided on both sides of the supporting member. The front frame is separated into an upper side portion and a main body portion, and the front frame is separated into an upper side portion and a main body portion, and the front frame is separated into an upper side portion and a main body portion. By attaching the upper side of the rear frame so that it can rotate and lifting the upper side of the rear frame with a cylinder provided on the main body of the rear frame, it is possible to easily handle tall cargo, etc., and to place the maximum amount of space on the loading platform. It is possible to obtain a lift-type truck with an opening/closing cargo roof that can load a large amount of cargo and improve transportation efficiency.
