Description

[Detailed Description of the Invention] The present invention relates to a forklift truck used for transporting, stacking and unloading cargo in warehouses and other locations.

In a conventional forklift truck, the movement of the truck and the vertical movement of the fork are controlled by a handle, an operating stick, etc. located at the driver's seat. However, when a large number of cans are placed on a pallet and a small number of cans, such as one or two cans, are to be taken out from each of the second and higher pallets from a stacked state, a forklift truck is required. A worker stands on a pallet with a safety shelf that is engaged with the fork of the lift, and the driver in the driver's seat operates the control stick to move the lift up and down while the worker lifts the cans on the pallet at each level. I was taking it out. Therefore, both the worker and the driver
I needed someone. In addition, when such work is carried out by one person, the pallet must be lowered down, the necessary cans taken out from it, and then the pallet is returned to its original place, which is not only inefficient but also very time consuming. It was dangerous.

The purpose of the present invention is to eliminate these drawbacks and provide a forklift truck that can be operated remotely while riding on a pallet using simple mechanical means. A rod is rotatably pivotally connected to the lower end of the forklift truck body at its root, and a connecting rod is pivotally connected to the upper surface of the forklift truck body at an intermediate portion thereof, and one end of the connecting rod is attached below the transmission rod. the other end is formed into a U-shaped portion, and the operating rod is engaged within the U-shaped portion;
A control lever is movably provided at the upper end of the column that moves the fork up and down as the column expands and contracts, and the root of the control lever is connected to the tip of the transmission rod.

One embodiment of the present invention will be described with reference to FIGS. 1 and 2.

1 is a forklift truck body, 2 is a fork that moves up and down with the expansion and contraction of a column 3 erected in front of the forklift truck, 4 and 5 are a handle and an operating stick installed in the driver's seat 6 of the main body 1, respectively. According to the tilting operation of the operating rod 5, a switching valve interposed in a hydraulic circuit between a hydraulic power source and a hydraulic cylinder is switched to move the piston rod of the hydraulic cylinder up and down, and in conjunction with this, the fork 2 is moved up and down.

Reference numeral 7 indicates an operating lever movably provided at the upper end of the column, 8 a telescopic transmission rod, and 9 a connecting rod. The connecting rod 9 is pivotally connected to the upper surface of the main body 1 in the middle thereof, and one end of the connecting rod 9 is connected to the lower part of the transmission rod 8, and the other end is connected in a U-shape. It was formed into a U-shaped portion, and the operating rod 5 was engaged within the U-shaped portion. Furthermore, the operating lever 7 is provided at the tip of the transmission rod 9. Note that 10 is a guide plate that guides the tilting direction of the transmission rod 8, 11 is a handrail provided at the rear end of the fork 2 to prevent the worker from falling, and 12 is a wire mesh that protects the worker's hands.

In this way, the forklift truck is moved to the front where a large number of cans are placed on the pallet 13 and these are stacked in multiple tiers, and after lowering the fork 2, the worker transfers to the pallet 13 attached to this and starts the work. The person operates the operating lever 7 while holding onto the handrail 11. That is, when the operator pulls the operating lever 7 toward the front or pushes it toward the opposite side as shown by the arrow in FIG. The operating rod 5 is tilted forward or backward, and the fork 2 is thus raised or lowered. Further, when the transmission rod 8 is placed in the neutral position by operating the operation lever 7, the operation rod 5 is also placed in the neutral position, and the fork 2 is brought to a stopped state. Accordingly, by pulling or pushing the operating lever 7 or setting it in the neutral state, an appropriate number of cans are taken out from each pallet in the same manner as in the previously described embodiment. Incidentally, as mentioned above, when taking out a small number of cans, it is preferable to install a fall prevention shelf.

As described above, according to the present invention, the operator can move the fork up and down by remote control using mechanical means while riding on the pallet engaged with the fork. Even in work such as taking out a small number of cans on each pallet from a multi-tiered pallet,
The work can be done by a human operator, and since it is composed of three rod-like members such as a transmission rod, a connecting rod, and an operating lever, the number of materials is extremely small, and the structure is simple and easy to manufacture. It has an effect that can be obtained at a low cost.
