Description

Warning machine

The invention relates to a stacker, in particular to a stacker with a warning function.

At present, the stacker is mainly used for loading, unloading, stacking or transporting industrial goods in a piece or a large number of stacked goods. Since the vertical lifting and horizontal movement functions of the goods can be provided, the handling and transportation process can be mechanized, thereby reducing Manpower use, reducing cargo damage and improving handling efficiency. It can be seen that whether it is transporting goods or performing projects, it is necessary to rely on the stacker. Therefore, it is now widely used in factories, warehouses, ports, airports, logistics centers, etc.

However, the driving work of the stacker must be carried out after a series of trainings and after obtaining the relevant licenses. However, during the driving process, it may still be caused by high-speed driving, poor line of sight, road inclination and reverse or reversing. Gong'an accident, especially during the driving process, there is no special warning on the cargo fork in front of the stacker. The high and low positions are not fixed, and the stacker is easy to make people feel alarmed when there is no pile of goods. If there is no warning sign or traffic guidance personnel at the scene, there is a great danger to the vehicles passing by the stacker. If you do not pay attention, the safety of the collision will occur, or you may not see the cargo fork. Stumbled, resulting in a tragedy.

It can be seen from the above description that the prior art stacker still has the following disadvantages in actual use:

I. Derivative security concerns

There are no special warnings about the conventional cargo forks, and the stacker is easy to lose alarm when there is no pile of cargo. Therefore, it is easy to derive doubts about the safety of personnel damage.

Second, the lack of special warning facilities for cargo forks

The conventional cargo fork is part of the extension of the car body. Due to the work requirements, the height of the fork is not fixed. It is easy to be dangerous when driving, poor line of sight, road inclination and reversing or turning. Lighting warning facilities are needed to remind people around. note.

Third, the height warning of the work of the stacker is unknown.

The conventional stacker is not a fixed object, and it will move at any time with the demand of the cargo work, and the moving process is not a separate body movement. It is necessary to plan the work warning area for moving with the vehicle, and the function is obviously missing.

The reason is that the present invention develops and designs a stacker that can improve safety and display a work warning area from the perspective of care, in-depth conception and active research.

In view of the above, it is an object of the present invention to provide a stacker that can generate an alerting effect.

The stacking machine with warning function comprises a body movable on a plane, a lifting mechanism disposed on the body and movable up and down relative to the body, a warning mechanism for causing the lifting mechanism to emit light, and a warning mechanism It is used to control the operating interface of the lifting mechanism and the warning mechanism. The warning mechanism can project light and display at least one warning area on the plane.

The beneficial effect of the invention is that the warning mechanism is used to make the lifting mechanism emit light and can project light to display a warning area on the plane, and the position of the lifting mechanism and the moving range thereof can be clearly displayed, and the heightening machine is driven during the driving process. Safety and reducing accidents can also assist lighting during nighttime driving to improve the safety of the stacker.
