Description

TRUCK CARGO BOX}

The present invention relates to a truck loading box, and in particular, a truck that can prevent freezing from occurring in a loading box of a truck, such as a rolling truck, a rolled-up truck, and a food collection truck, which loads and loads a moisture-containing load into the loading body. It is about a loading box.

In general, trucks such as a rolling truck, a presser truck, a presser truck, and a food truck are transported to a destination that does not have a specific size, such as waste or household waste generated at a construction site or apartment, and is provided at the lower part of the front of the stacker. It is a kind of construction equipment that automatically unloads load to the destination by the hydraulic lifting device.

The loading bins of these trucks consist of a pair of vertical side plates, a horizontal bottom plate and a tailgate to carry relatively heavy loads, each of which has a horizontal frame forming the shape of the member and the horizontal frame. A number of longitudinal frames are reinforced on the outside to increase the support strength by welding. Such a loading box has a rectangular section of approximately '∪' shape in order to maximize the loading volume of the loading box.

Since most of the loads loaded into the truck's loading box contain water, in the environment where the temperature drops to below zero, such as winter, the water of the load freezes during transportation, which increases the weight of the truck in addition to the load. This reduction caused economic losses and even made the loading impossible.

In this case, when the load is frozen in the loading box, the freezing part of the bottom of the loading box is manually input and scraped by hand, or by using an excavator, the freezing part of the loading surface is scraped. This is required, and in the latter case, problems such as damage to the bottom of the loading box due to excavators have occurred.

In order to solve this problem, Korean Patent Publication No. 10-2000-0055842 (published date: September 15, 2000) and Korean Patent Registration No. 10-0289833 (registration date: February 23, 2001) have been proposed.

The prior art relates to a dump truck loading box heater, an induction pipe branched from an exhaust pipe of an engine, a heating tube installed on an inner surface of a dump truck, and an exhaust gas inlet valve connecting the induction pipe and the heating tube. In order to solve the difficulty of loading and unloading the material loaded in the truck loading box in winter.

However, the above-mentioned prior arts provide a portion of exhaust gas generated by combustion of fuel in an engine to a heating tube to heat a load carried in a loading box by the heat of the exhaust gas. Accordingly, problems such as corrosion of the loading box due to sulfur oxides and the like contained in the exhaust gas have occurred.

Accordingly, the Republic of Korea Patent Registration No. 10-0921436 (Registration Date: 2009. 10. 06) has proposed a 'sewage freezing prevention system of the garbage collection vehicle collection box using the heat conduction method'.

The sewage freezing prevention system includes a heat conduction unit that is heated by the heat of the exhaust box of the cleaning vehicle, and a heating unit having a heat wire unit therein that receives heat through the heat conduction unit and transfers the heat to the collection of the cleaning vehicle. To prevent freezing.

However, in the sewage freezing prevention system, since a heating unit having a hot wire unit is directly installed at the bottom of the collection box, the heating unit may be easily damaged by the load when a relatively heavy load is loaded. As a result, it can only be applied to a cargo box of a truck that loads relatively light loads, and its use is extremely limited. In addition, since the heat conduction part must be manufactured using a material having high thermal conductivity in order to transfer heat from the exhaust pipe to the heating part, problems such as an increase in manufacturing cost may occur.

As illustrated in FIG. 9, the foreign substance discharge pipe 37 is preferably installed in a support frame installed closest to a tailgate (not shown) mounted on the main body of the loading box 30 among the support frames 32. And the foreign matter discharge pipe 37 is installed so as to communicate with the foreign matter communication pipe 38 which communicates with the lower central portion of the support frame 32.

The sealing member 44 may have a structure in which one surface facing the foreign substance discharge pipe 37 is convex so as to have a constant weight. The sealing member 44 is hinged to the foreign matter discharge pipe 37 by one side through the fastening member 43 to open or close the foreign matter discharge pipe 37 in accordance with the lifting and lowering of the loading box 30. That is, in the state where the loading box 30 is placed in the truck 1 as shown in FIG. 1, the discharge port of the foreign matter discharge pipe 37 is sealed by the weight thereof. Then, in order to unload the load loaded in the loading box 30 in a state where the discharge port of the foreign substance discharge pipe 37 is closed, the front of the loading box 30 (the front of the truck forward direction) is lifted through the loading box lifting device of the truck 1. When raised, the direction in which gravity acts changes and is separated from the outlet of the foreign matter discharge pipe 37 by its weight to open the outlet of the foreign matter discharge pipe 37.

Referring to the freezing prevention method using a truck loading box according to the present invention having such a configuration as follows.

1 to 3, first, an exhaust gas is generated in a process of driving an engine, and the exhaust gas is transferred from the engine exhaust manifold to the muffler 3 through the cut pipe 3.

The muffler 3 dissipates a large amount of heat due to the exhaust gas emitted from the engine. The heat emitted from the muffler 3 is received inside the heat exchange chamber 10 without escaping to the outside.

When the outside air flows into the air circulation passage 11 through the air inlet 12 of the heat exchange chamber 10 while the heat to be emitted from the muffler 3 is received inside the heat exchange chamber 10, the heat exchange chamber 10 The air introduced into the air circulation passage 11 is heated by the heat accommodated in the inside.

The hose 20 delivers hot air delivered from the heat exchange chamber 10 to at least one of the supporting frames 32 of the loading box 30 as shown in FIGS. 5 to 7.

The hot air delivered to the support frame 32 is circulated through the inner empty space of the support frame, and neighbors are circulated through the communication frame 33 or the horizontal frame 35.

Heat is transferred to the main body 31 of the loading box 30 by hot air circulating through the support frame 32 and the communication frame 33 or the support frame 32 and the horizontal frame 35. Since the main body 31 and the support frame 32, the communication frame 33, and the horizontal frame 35 are in contact with each other, the main body 31 is circulated through the interior of the support frame 32, the communication frame 33, and the horizontal frame 35. Heat generated from the hot air is transferred to the body 31 as it is.

The main body 31 is open even when loading a load containing moisture in the loading box 30 at the time of freezing by the heat transferred from the support frame 32, the communication frame 33 and the horizontal frame 35, so that the moisture of the load It does not freeze. Accordingly, since the weight of the truck due to the freezing of the load does not increase, the amount of the load on the loading box is reduced, thereby preventing economic losses from occurring and solving the difficulty of unloading the load.

In the present invention, the air heated by the muffler as an example of the heating medium to prevent freezing of the loading box 30 has been described as an example, but the heating medium may be a liquid as an example.
