Description

[Detailed description of the invention] The presser plate of conventional load stabilizers was attached to and supported by an arm that moves up and down with the guide bar, but it requires a lot of effort to remove it when it is not needed or becomes an obstacle when handling cargo. It was necessary.

The present invention was proposed in order to solve the above-mentioned drawbacks of the conventional method, and it is possible to store the holding plate by folding it downward without removing it.It also has a stabilizer holding plate that is conventionally used for folding and unfolding operations. It is an object of the present invention to provide a load stabilizer that utilizes an operating cylinder and does not impair its operating length.

The present invention will be described below with reference to the embodiments shown in the drawings. Reference numeral 1 denotes a presser plate, and 2 represents a pin that serves as a fulcrum when the presser plate 1 is moved up and down. Reference numeral 3 denotes a hook pin, which engages with a hook at the tip of a hook 4 and is provided on the presser plate 1. The hook 4 is connected at its lower part to a shaft 5 attached to a lever 8.

7 is a hydraulic cylinder, and the upper piston rod 7
The tip of the cylinder a is pivotally connected to the presser plate 1 by a pin 6, and the lower end of the hydraulic cylinder 7 is pivotally connected to the main body 11 by a pin 6a. The main body 11 is movably mounted on a mast main body 14 in a mast device of a forklift truck (not shown), and is moved up and down by operating a lever from the driver's seat.

A guide 9 is attached to the upper part of this main body 11, a guide rod 10 is fitted into the guide 9, and a support part 10 is attached to the upper part of the rod 10.
The presser plate 1 is pivotally attached to the pin 2 at the a. Therefore, due to the vertical movement of the hydraulic cylinder 7,
A presser plate 1 moves up and down using a pin 2 as a fulcrum, and holds down the load at a required height to prevent the load from collapsing.

12 is an adjustment bolt, which is screwed onto the tip of the lever 8, and the tip of the bolt 12 is connected to the mast body 14.
It is adapted to come into contact with a stopper 13 attached to the. Also, 15 is a fork.

Next, to explain the operation, FIG. 2 shows normal use with the presser plate 1 in its restored state. In this state, since the hook 4 is engaged with the hook pin 3, the operation of the cylinder 7 continues to move the presser plate 1 up and down together with the guide rod 10.

In Figure 3, the main body 11 is lowered from the state shown in Figure 2, the adjustment bolt 12 attached to the lever 8 comes into contact with the stopper 13, and the shaft 5 is also lowered in the same way, so the lever 8 is tilted and the same shaft 5 is rotated. As a result, the hook 4 also tilts, indicating a state in which it is disengaged from the hook pin 3.

Next, when the piston rod 7a of the hydraulic cylinder 7 is extended, the presser plate 1 is bent around the pin 2 as a fulcrum, as shown in FIG. 4, and is in the stored state. Further, the presser plate 1 is restored to its original state by retracting the hydraulic cylinder 7 from the state shown in FIG.

Since the present invention is configured as explained in detail above, by lowering the presser plate support member and extending the piston rod of the hydraulic cylinder, the presser plate can be folded and stored, and the operating range of the stabilizer is It is possible to handle large loads exceeding .

In addition, the hydraulic cylinder that operates the pressure plate can be used to store and restore the pressure plate, so no additional operating lever is required. As described above, in this device, the pressure plate can be stored and restored by moving the pressure plate support member up and down and operating the hydraulic cylinder, so it can be easily operated from the driver's seat and is simple to use.
