The present invention relates to a work device of an industrial vehicle, and more particularly, a work device of an industrial vehicle for mounting and separating various work machines on a link assembled to a boom carriage of a heavy equipment such as a crane or a telescopic handler. It is about.

Industrial vehicles are used in construction sites, such as industrial construction, buildings, civil and factory buildings, construction sites, etc. Usually, heavy equipment includes forklifts, cranes, telescopic handlers, and the like.

A forklift is a work such as loading a work used in a construction site or an industrial site at a vehicle or a predetermined position, or unloading a loaded work at a short distance and moving the work at a short distance. It is to do limited work such as letting go.

On the contrary, cranes are fixed and mobile, and fixed cranes include tower cranes for lifting and lowering a workpiece above a certain height depending on the work range and ability. A mobile type is usually fixed when lifting and lowering a workpiece. However, there are telescopic handlers and the like capable of moving a workpiece below a predetermined weight to a predetermined distance.

The telescopic handler can perform a function of a forklift and a crane at the same time, and is widely used in an industrial site or a building site. The telescopic handler can carry the aerial work or the work in the construction or construction site according to the working capacity, and in the small case, it can work on the narrow road.

Conventionally, when attaching and detaching various work machines to the telescopic handler, the mounting part of the work machine is manually coupled with a stopper, a pin, or the like to a stay bar formed in the carriage.

In the above case, a separate pin or stopper is applied, which may cause the pin or stopper to be lost, and the fork assembly may be lifted due to an unstable mounting state, or when a plurality of work machines, for example, forks are coupled. There was a hassle to combine by hand.

Furthermore, as a working device of a telescopic handler, Korean Utility Model Registration No. 186868 has been registered, which includes a carriage having left and right fixing plates, and first and second stay bars mounted side by side through the left and right fixing plates of the carriage. And a pair of forks having first and second holes fitted to the first and second stay bars to enable vertical movement.

This is a two-point coupling that does not lift the tip of the machine, but it also requires one or more forks to be joined manually, and when the workpiece is loaded with a certain weight or more, the coupling state is unstable and the manual coupling method is adopted. As a result, the trouble of the worker replacing the work machine remained.

An object of the present invention is to provide an automated link device that can easily mount and detach various work machines on a boom carriage of an industrial vehicle, in order to solve the conventional problems.

The present invention, for the above purpose, the plate is inserted and the left fixing plate coupled to the upper and lower working machines; A right fixing plate connected to the hub pipe at a predetermined interval with the left fixing plate to be compatible with each other, and having a diaphragm inserted therein and a working machine coupled to the upper and lower ends thereof; A link case coupled between the left fixing plate and the right fixing plate and having a space therein; A stopper mounted between the right fixing plates to control mounting and detachment of the work machine; A first coupling member fixed to the hub pipe and having a boom carriage coupled thereto; It can be achieved by providing a work attachment device of an industrial vehicle comprising a second coupling member fixed to the hub pipe and coupled to the carriage cylinder.
