Description

[Detailed explanation of the invention] This invention is an ALC version (lightweight aerated concrete version)
This relates to the forks of a forklift that transports objects in a stacked state.

For example, when unloading ALC plates stacked on a truck loading platform via a rootstock using a forklift, insert a fork claw between the rootstocks at the bottom of the ALC plate and then lift it up to remove the ALC plate from the rootstock. It will lift up. By the way, when lifting the fork claw, it is not easy to simultaneously touch the entire width of the lower surface of the lowermost ALC plate, and depending on the inclination of the fork claw when lifting, the fork claw can be applied to the widthwise edge of the lowermost ALC plate. If it hits the lower part, the local load applied at that time tends to cause damage to that part.

Conventionally, measures have been taken to control the insertion length and inclination of the fork claws so that when lifting, the tip of the fork claws first hits the reinforcement part a certain distance in front of the end of the ALC plate in the width direction opposite to where the claws are inserted. However, all of these depended on the skill level of the forklift operator.

This invention was devised to solve the above-mentioned conventional problems all at once, and when inserting a fork claw,
Equipped with a positioning display mechanism that corresponds to the width direction edge of the ALC plate (especially the lowest ALC plate), and a four-point support mechanism that supports the reinforcement part of the ALC plate set at a fixed position on the fork claw by this mechanism. It is characterized by

The present invention will be explained below with reference to illustrative embodiments.

In the figure, 1 is a fork of a forklift, and a pair of steel plate support pieces 3 on the front and rear sides project upward at the tip and intermediate portions of the fork 1, spanning the fork claws 2 that protrude left and right in front of the fork 1. They are installed at intervals.

This plate support piece 3 connects left and right plate support parts 3a located on the fork claw 2 via a connecting part 3b,
A reinforcing part 3c is provided at the lower part of the connecting part 3b, and a slope part 3d extending forward downward is provided over the entire length at the upper part of the insertion side end of the plate support part 3a and the connecting part 3b.
It is for supporting the ALC plate, and the installation interval is
For example, ALC version 4 with a length of 3000mm and a width of 600mm has a value of 400.
The fork claw 2 can be attached and detached using, for example, a magnet, a clamp mechanism, a screw mechanism, a double-sided adhesive tape, etc. so that it can be adjusted according to the width of the printing plate.

Reference numeral 5 denotes a switch and battery box, and a switch bar 6 protrudes from the top of the box 5, which can turn on a switch set inside. This switch bar 6 is arranged so that when the ALC plate 4 is set on the fork claw 2 so that the center in the width direction is located directly above the center between the plate support pieces 3, it comes into contact with the end of the ALC plate 4 in the width direction of the claw insertion side. , is attached to the rear plate support piece 3 by a mounting piece 6.

7 is an indicator such as a buzzer or miniature light bulb, which is connected to the switch and the switch in the battery box 5 via an electric wire 8, and when the switch is closed by tilting the switch bar 6, an indicator is displayed to the driver of the forklift. It is possible to generate an alarm.

In the above configuration, the
When the fork claw 2 is inserted between the rootstocks 9 at the bottom of the ALC plate 4 in order to transport it by a forklift, the switch bar 6 hits the end of the lowermost ALC plate 4 in the width direction of the claw insertion side, and the switch bar 6 touches the end of the lowermost ALC plate 4 in the direction of the claw insertion width, causing the rearward Since the switch and the switch in the battery box 5 are turned on, the display device 7 issues an alarm by lighting up or buzzing.

When the operator of the forklift stops the insertion operation of the fork claw 2 due to this warning and then lifts the fork claw 2, the plate support portion 3a
hits the reinforcement part of ALC version 4, and fork claw 2
will not hit the width direction edge of ALC version 4.
The ALC plate 4 is supported by the plate support portions 3a at four locations, front, rear, left and right, and is lifted up in a stable state.

In addition, the left and right plate support parts 3 that constitute the four-point support mechanism
Although the portions a are connected to each other via the connecting portion 3b, they may be independent from each other. In addition, although the plate support portion 3a is removably attached to the fork claw 2,
It may be formed integrally with.

Although the switch constituting the positioning display mechanism is provided on the rear plate support portion 3a, it may also be provided on the rising portion (preferably at the bottom) of the fork.

As described above, although the present invention has an extremely simple configuration, it is possible to lift stacked ALC plates easily and quickly without damaging them when transported by a forklift, improving the efficiency of transportation work. This is something that can be achieved.
