Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a side clamp device for a side clamp type material handling vehicle such as a side clamp type forklift truck.

Conventional side clamp devices for cargo handling vehicles are designed to clamp loads using only the clamp arms on both sides, which makes it impossible to handle relatively small loads at the same time. There is a problem.

The present invention was completed with the aim of providing a side clamp device for a cargo handling vehicle that solves the above-mentioned problems.Hereinafter, a side clamp type forklift truck shown in the drawings will be described in detail as an example.

Reference numeral 1 denotes a vehicle body, and a side clamp device main body 4 is installed on masts 2, 2, which are erected and opposed to each other at the front of the vehicle body, through guide rollers 3 so as to be movable up and down. Reference numerals 5 and 5 designate clamp arms of the side clamp device main body 4, and the clamp arms 5 and 5 have guide rod portions 7 with guide rollers 6 provided at their respective bases, and are moved forward and backward with a cylinder device 9 within a frame 8. This point is similar to the well-known clamp arm, but when a sheet pallet is interposed below the lower ends of the clamp arms 5, the both ends of the clamp arms 5 are inserted. , 5 are provided with sheet gripping devices 10, 10 for gripping the sheets. That is, each clamp arm 5 shown in the illustrated embodiment has an appropriate number of hydraulic cylinders 11 and guide portions 12 vertically provided between its inner plate portion 5a and outer plate portion 5b. A presser member 14 provided at the lower end of the presser member 13 is moved toward and away from a receiving frame 15 provided oppositely below the presser member 14,
When the piston rod 13 is lowered by the hydraulic cylinder 11, the presser member 14 guides its guide rod 16 to the guide portion 12 and is lowered to the receiving frame 15.
Both ends of the sheet pallet can be held between the holding member 14 and the holding member 14.

With this structure, in normal cargo handling work, the load can be clamped from both sides using the clamp arms 5 of the side clamp device main body 4, unlike the side clamp devices of conventional cargo handling vehicles. However, in the present invention, the clamp arms 5, 5 are provided with sheet grip devices 10, 10 for clamping both ends of the sheet pallet below the clamp arms 5, 5, so that it cannot be carried out with the conventional side clamp device. It has the advantage of being able to handle so-called bulk cargo. That is, when it is desired to handle a large number of relatively small pieces of baggage at the same time, a large number of pieces of baggage are stacked on a sheet pallet called a slip sheet to form one unit, and this unit is equipped with clamp arms 5, 5. At the time of side clamping the sheet pallet, both ends of the sheet pallet are held in the receiving frames 15, 15, which are part of the sheet gripping devices 10, 10.
Then, by operating the hydraulic cylinder 11 and lowering the holding member 14 at the lower end of the piston rod 13, both ends of the sheet pallet are attached to the holding members 14 of the sheet gripping devices 10, 10 and the receiving frame 15.
Therefore, even if the side clamp device main body 4 is moved up and down in this state, the bulk cargo unit is not only held from both sides by the clamp arms 5, but also by the seat grip device 10. , 10, which are supported from below by the sheet pallet toy, which prevents the cargo from falling and allows the cargo handling work to be carried out properly.

As is clear from the description of the above embodiment, the present invention is equipped with a sheet grip device on the clamp arm that can grip both ends of the sheet pallet at the lower end of the clamp arm. Not only can it perform cargo handling work, but it also has the advantage of being able to accurately and easily handle bulk cargo using sheet pallets without the need for special attachments. The practical value is extremely great as it solves the problem.
