Description

SPECIAL PURPOSE VEHICLE THAT CAN BE AUTOMATICALLY BALANCED WHEN LOADING}

The present invention relates to a specially equipped vehicle capable of automatically adjusting the balance when loading a cargo, and more specifically, when the arm roll box is pulled up, the switching operation is performed by automatically lowering the reaction axis of the balance adjusting sensing part in the process of the arm roll box sitting down. In this way, when power is supplied, the arm roll box is lifted to a certain height to balance it, so that it can prevent the damage of vehicle parts such as shock absorbers and springs. It is about.

Generally, a specially equipped vehicle is a vehicle with special facilities and structures, such as a cleaning vehicle, ambulance, fire engine, crane, snowplow, mixer truck, and tank lorry. There are various types of vehicles such as vibration-free trailers and dump trucks. In addition, transportation vehicles that transport ultra-low temperature and high pressure gas, ladder vehicles used in the construction and construction fields, medical and broadcasting, radio wave measurement vehicles, cranes, ladder vehicles, and special nuclear power plants can be considered as a special vehicle. Also, missiles and self-propelled artillery among military transport means can be classified as special vehicles.

Among these, the arm roll box loaded on the cleaning vehicle among the special vehicles is also called a cleaning box, and it can be said to be a type of container for loading an object for cleaning.

According to the definition of the International Organization for Standardization (ISO), this 'container' has a strength to withstand durability and repeated use, and it can be linked to one or more transport methods, and is specially designed to transport products. It is defined as a transportation device with a volume of 35.3 cubic bits or more, with a window for easy handling, and a product designed to easily fill and withdraw products, especially when the handling contents change from one transportation method to another. have.

The container is various according to the type of cargo to be accommodated, the main transport engine, structure, material, load, shape, etc., and those having a volume of 3 m 3 or less are called small and more than large.

Advantages of the container transport include mechanization of unloading, reduction of packaging cost, and prevention of theft.

There are various types of containers such as a tank container for transporting liquid cargo, an inner container for transporting cargo requiring temperature control, and a container for transporting cargo that does not require temperature control, a ceiling or side open container.

On the other hand, in order to collect daily waste or construction waste generated from daily life or construction sites and transport it to a landfill or treatment site, a container for collection is installed on site and loaded with waste, which is towed by a dedicated truck, that is, an arm roll truck, to dispose of waste. It is moved to a dedicated treatment plant for disposal or recycling.

Therefore, in order to solve problems such as safety accidents in the process of loading and collecting the collected wastes into a large container (arm roll box) as described above and transporting them to a landfill or treatment plant, containers loaded with vehicles and containers are safely mounted. It is a functional device to prevent safety accidents (large accidents on the road) in advance by preventing the driver from getting uncomfortable as well as the driver's anxiety.

Here, to explain in more detail about the arm roll truck (vehicle), for example, the spreader is temporarily used in the winter, but after loading and using the spreader on a truck equipped with a loading box, after the winter season, the spreader is unloaded and stored. Is done.

Therefore, in order to reduce the damage caused by unexpected snowfall and snowfall in the winter season, it is very important to relieve the freezing of the road surface by using a sprayer.

Conventionally, when loading or unloading a sprayer on a vehicle, a traction device such as a crane is used to mobilize a lot of manpower, and thus there is a problem that the equipment rental and labor costs are increased and a lot of time is required accordingly.

Therefore, as described above, a truck that compensates for the disadvantages of a truck in which a conventional container is separable is an arm roll vehicle equipped with an arm roll.

The conventional arm roll vehicle 10, as shown in FIG. 1, pulls or pushes the loading unit 11 with a hook 12 for loading the arm roll box 20, and the loading unit 11 A hydraulic cylinder (not shown) is provided for the frame roller 14 to facilitate the loading and unloading of the arm roll box 20 when the arm roll box 20 is loaded, unloaded or unloaded on both sides of the hydraulic cylinder. Is composed.

The arm roll vehicle 10 configured as described above hangs the hook 12 installed on the loading unit 11 on the hook ring 21 formed on the arm roll box 20 to load or unload the arm roll box 20.

At this time, when the arm roll box 20 being loaded or unloaded is supported, the roller 14 provided on one side of the subframe 13 of the arm roll vehicle 10 is supported, and when the other side is in contact with the upper surface of the subframe 13, sliding Move.

However, having the above configuration, there is a problem that causes the occurrence of a serious secondary safety accident when the waste is loaded on the arm roll box 20.

That is, when solid or liquid, such as sludge is loaded in the arm roll box 20, the center of gravity of the arm roll box 20 is moved to the rear by the loaded waste, and the arm roll box 20 is also moved. When pulling up, the arm roll box 20 may sag and collapse, and in this process, the shock absorber and the spring are damaged, thereby damaging the vehicle.

In addition, when operating an arm roll vehicle with a shock absorber or a spring damaged, a vehicle may face a dangerous situation in the course of operation, causing serious traffic safety accidents, and an arm roll box that hesitated during the loading process of an am roll vehicle There is an urgent need for a technique to prevent the shock absorber and the spring from being damaged by lifting the product to its original position to adjust the balance (balance).
