Abstract

(57) [Summary] (Corrected) [Purpose] A crane truck is used to convey and install heavy loads, or a load truck equipped with a simple truck that does not load and unload loads manually. Provide fried and unloading equipment. [Structure] A load supporting truss 2 also serving as a hood that is detachably attached to a loading platform of an ordinary truck 1 is provided, a load supporting beam 3 is provided above the load supporting truss 2, and can be freely taken in and out, and a load lifting beam 3 is provided at a tip of the load supporting beam 3. Equipment equipped with the winch 4 of.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device that conveys a heavy load to a predetermined position to load and unload the heavy load.

[0002]

[Prior art]

 Conventionally, in order to transport and set heavy load at a predetermined position, it can be transported by crane trucks, loaded and unloaded, or transported by ordinary trucks or carts and manually loaded and unloaded. The relatively light ones were hand-carried and set in place.

[0003]

[Problems to be solved by the device]

 However, if a crane vehicle is used as described above, it will be a large-scale operation and it will not turn quickly, and a crane-equipped truck called a unic vehicle is expensive and uneconomical. On the other hand, it is extremely inefficient to carry by trucks or carts to load and unload heavy loads. Therefore, we have developed a device that can be transported using a general truck, and can be loaded and unloaded easily by an electric motor using the truck's engine battery.

[0004]

[Means for Solving the Problems]

 A truss for loading and unloading, which also serves as a hood frame, is attached to the truck, and a load-bearing beam mechanism that can be expanded and contracted by an engine battery is provided behind the truck on the upper part of the truss, and the engine of the truck is attached to the tip of the load-bearing beam. The equipment is configured with a battery-driven lifting winch.

[0005]

【Example】

 An example is shown in FIG. A load supporting traverse 2, which also serves as a removable top frame, is attached to the bed of the truck 1, and a load supporting beam 3 is provided on the upper portion of the load supporting truss 2 so as to be retractable toward the rear of the truck 1. A lifting winch 4 composed of an electric motor driven by an engine battery is attached to the tip of the load supporting beam 3.

FIG. 2 shows an example of a conceptual diagram of the expansion / contraction mechanism of the load indicating beam 3. A second rail 3b having a roller 5 rolling inside a first rail 3a composed of two U-shaped members facing each other is similarly formed by two U-shaped members and further rolled in the second rail. The load supporting beam 3 is constituted by the front end member 3c having the roller 6. A rod or a plate member 9 is pin-joined to the tip end of the tip member 3c at a point B, and the other end of the rod member 9 expands and contracts the rod member 9 from the track 1 so that it can be installed in an electric motor driven by an engine battery. A pin is joined to part C of the chain 8 hung on the worn sprocket 7. FIG. 3 is a view taken along line AA of FIG. 2 and 3 show that the load supporting beam 3 is fully extended. When the sprocket 7 rotates and the pin joint point C moves to the right, the load supporting beam 3 contracts.

The roller is in contact with the lower side when a load is applied, and is in the upper side when the load is distant from the load, and therefore the rail is made larger than the diameter of the roller. Also, for example, a limit switch or the like is regulated so that the pin joint point C between the rod or the rod member 9 and the chain is not unduly overrun.

Both the winch electric motor for hoisting and the electric motor for extending and contracting the load supporting beam 3 are cables and are hand control switches.

The load supporting beam 3 is extended to an appropriate position for the heavy load 10 to be lifted, the load lifting winch 4 is driven to lift the heavy load 10, and the load supporting beam 3 is contracted to the load supporting truss 2. Store and transport. This reverse operation should be performed when a heavy load of 10 is installed. When the truck 1 is used as an ordinary truck without using this device, the hood / load supporting truss 2 may be removed from the truck bed.

[0010]

[Effect of device]

 It does not require large-scale dedicated equipment such as a crane truck, and can load and unload heavy loads without manual labor and set the load at a predetermined position.
