Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides, in an industrial vehicle such as a forklift truck, which is equipped with a lift mechanism on a part of the vehicle body, a lift bracket that is attached to the lift mechanism so as to be able to rise and fall so that the left and right spacing can be adjusted. The present invention relates to an improvement in a side stabilizer device including a pair of supported clamp arms.

In conventional devices of this kind, the load on the fork is held by a pair of left and right clamp arms to prevent it from collapsing while traveling, but when this load is placed on a shelf in a warehouse, Since there is a gap on either side of the cargo due to the width of the clamp arm, the loading efficiency is reduced.

The present invention has focused on the above-mentioned drawbacks, and has been designed to protrude forward during driving to help hold the cargo, and at times to retract to the rear so that only the cargo is placed on the shelf, making loading more efficient. The aim is to improve

Hereinafter, one embodiment of the present invention will be explained based on the drawings.
The figure is an overall side view, and a fork F for loading a load is attached to a lift bracket L that is movably supported by a main mechanism M such as a mast attached to the front of the vehicle body T of a forklift truck. has been done.

3 in the figure is an arm support, and the support 3 is
Lift brackets L-L are connected to the outer ends of a pair of upper and lower clamp rails 7, which will be described later, in order to move them synchronously.
A clamp arm 1 is rotatably attached to the upper end of the arm support 3 via a shaft 2.
A clamp arm rotating cylinder 4 is extendably inserted between the arm support 3 and the arm support 3.

FIG. 2 is a front view of the left half of the side stabilizer device shown in FIG. 1, viewed from the front, and the right half is omitted because it is symmetrical.

A clamp rail holder 5 having guide holes formed in the upper and lower sides is fixed to the front surface of the lift bracket L, and a pair of upper and lower clamp rails 7.7 can slide in the left-right direction with respect to the guide holes of the clamp rail holder 5. The arm support 3 is fixed to the tip of the arm support 3.

A clamp cylinder 6 is extendably inserted between the arm support 3 and the clamp rail holder 5, and the movement of the cylinder 6 is simultaneously transmitted to the upper and lower clamp rails 7 via the arm support 3.

A shaft 2 is fixed to the upper end of the arm support 3,
A clamp arm 1 is rotatably supported on the shaft 2.

As a means for regulating the rotational position of the clamp arm 1, a pin 1b is installed between a bracket ia fixed to the clamp arm 1 and a bracket 3a fixed to the arm support 3.
A cylinder 4 for rotation of the clamp arm is provided, which is telescopically inserted via t 3b.

Piping, control valves, pumps, tanks, etc. for telescopically operating the lamp arm rotating cylinder 4 and clamp cylinder 6 are omitted.

Next, the effect will be explained.

First, after placing a load on the fork F, the clamp cylinder 6 is retracted to narrow the inner distance between the left and right pair of clamp arms 1, 1, and if the space is stopped when they come into contact with the load, the load can be moved upward and forward. The forklift truck is supported by the clamping force of the clamp arms 1 and 1, so even if the forklift truck is run in this state, the vibrations during the drive may cause the load to collapse or become damaged. No part of it will fall off.

When the loading position is reached, the fork F is raised to a predetermined height by the owner mechanism M such as a mast, and then the clamp cylinder 6.6 is extended to release the clamping force of the clamp arms 1, 1 against the load. At the same time, the clamp arm is moved left and right outward so that the clamp arm 1.1 is positioned outside the width of the vehicle body T of the forklift truck, and when this is completed, the clamp arm rotation cylinders 4, 4 are extended and the clamp arm is moved. 1,1 first
If the load is rotated approximately 90 degrees downward from the horizontal position shown in the figure and evacuated to the rear, the load will be exposed on the fork F, and if the forklift truck body T is continued to move forward, the clamp arm 1 will block the load in the width direction. It is possible to stack cargoes in contact with each other without having to do so.

FIG. 8 is a partial front view showing another embodiment, in which the arm support 3 and shaft 2 in FIG. 2 are omitted.
The feature is that the clamp arm 11 is rotatable with respect to the clamp rail holder 5 together with the upper clamp rail 18, and both ends of the clamp arm rotation cylinder 14 are connected to the clamp arm 1 through pins iib and izb, respectively.
Bracket 11a fixed to 1 and lower clamp rail 1
It is connected to a bracket N7a fixed to 7.

The tip of the clamp cylinder 6 and the lower clamp rail 17 are connected by an arm support N7c, and the upper end of the arm support TL7c is adapted to engage with an annular groove 11C provided in the clamp arm 11. Through this engagement part, the clamp arm 11 and the upper clamp rail 18 integrally move left and right as the clamp cylinder 6 expands and contracts, and the clamp arm rotation cylinder 1
Consideration is given so that the rotational force associated with the expansion and contraction of the arm support 17c is not transmitted to the arm support 17c.

According to the present invention, the clamp arm of the side stabilizer can be retracted rearward during loading, so that gaps between the loads can be eliminated during loading, thereby improving loading efficiency.

In addition, with the clamp arm retracted backwards, normal cargo handling work and long objects that do not require a side stabilizer device can be performed, so the scope of application is expanded compared to conventional side stabilizer-only devices. There are advantages.
