Description

Fiber reinforced plastic wing body for cargo trucks

The present invention relates to a fiber reinforced plastic wing body for a cargo vehicle, and more particularly, to reinforce a fiber for a freight vehicle, by forming the wing into a fiber reinforced plastic (FRP) to increase the strength of the wing and reduce the weight. It is about a plastic wing body.

In general, a cargo vehicle produced by an automobile company has a structure in which the loading box of the vehicle has no cover and can open and close only both sides and the rear wall.

Cargo vehicles with such a structure require a lot of manpower and time for packing and fixing cargoes, since each cargo must be packed and fixed with ropes of various materials to prevent the cargoes from falling out of the cargo box. In addition to the inconvenience, there is a problem that the loaded cargo can not be completely prevented from falling out of the loading box during transportation.

In addition, even if a cover is used to cover the entire cargo, there is a problem that the cargo cannot be completely protected from snow and rain seeping through seams or torn portions of the cover.

Accordingly, vehicle users who purchase freight vehicles prefer to install a separate structure in which the entire cargo box is completely sealed from the outside.

Such a cargo box closed structure includes a box type freight vehicle, and a box vehicle is classified into a cabinet type that is opened only in the rear and a wing body type that opens in both sides. The former cabinet type has the advantages of low manufacturing cost and complete protection of cargo, but it is not good workability because cargo has to be loaded and lowered only at the rear. On the other hand, the latter wing body type has the advantage of satisfying both cargo protection and workability.

In the wing body of a conventional freight vehicle having such an advantage, as shown in FIG. 8, two wings 51 and 53 are installed to be opened and closed to both sides of the loading box, and these wings 51 and 53 are formed of both wings. The hydraulic cylinders 55 and 57 provided at both ends are opened and closed.

However, when the hydraulic cylinder (55, 57) is used as the operation means of the wings (51, 53), the operation is excellent, but the structure is complicated, so there is a problem in frequent use and high manufacturing price.

The wings 51 and 53 of the wing body are typically manufactured by attaching a galvanized iron plate 61 to the outside of the body frame made of the square pipe 59 as shown in FIG. 9. Therefore, such a wing body needs to use a thin plate as much as possible because the thicker the thickness of the iron plate 61 is used, the higher the weight and manufacturing cost of the entire loading box. Because of this necessity, the steel plate used to make the wing body is usually 1 mm or less in thickness. However, the use of such a thin steel sheet has a weak mechanical strength of the steel plate because the steel plate itself bumps the cargo loaded therein or is easily torn apart even in a light external contact accident with other vehicles.

In addition, the conventional wing body is a riveting operation by attaching the iron plate 61 to the body frame. However, if the riveting work simply attaches one iron plate to the body frame, the task may be simple.However, in order to manufacture wing body, several iron plates must be cut and attached continuously, and the iron plate used is several meters or more. In order to manufacture the wing body for a large cargo vehicle using a large number of rivets, and when the long plate is riveted to the square frame, it is necessary to attach a thin and long plate without sounding, so highly skilled workers are required. Therefore, there is a problem that a lot of time and manufacturing cost is required to produce a single iron wing body.

In addition to these problems, the wing body made of iron plate has a problem that can not be used for a long time because the riveted portion is corroded when used for a long time and the corroded portion is torn by the vibration due to the vibration of the vehicle driving.

Another problem of the conventional wing body is that the wing body manufacturing method is complicated. In order to install a conventional wing body in a freight vehicle, including the bottom of the iron plate or wooden loading box completely removed to the frame supporting the floor, and then install a new wing body frame and a new floor and then install the wing body. Therefore, the conventional wing body is a long manufacturing time and a lot of manufacturing costs because of the complicated manufacturing method.

The present invention is devised to improve the problems of the wing body made of the iron plate as described above, the object of the present invention is to minimize the weight of the wing body itself and at the same time can greatly improve the strength, and also relatively easy without skilled functions It is to provide Fiber Reinforced Plastic wing body for the cargo vehicle that can make the wing body.

Still another object of the present invention is to provide a method of manufacturing a fiber reinforced plastic wing body for a freight vehicle, which is simple and convenient to manufacture, and a wing body can be manufactured within a short time.

At this time, the external force acting on the surfaces of the left and right wings 5 and 5 'by the extension of the cylinders 15 and 15' is dispersed and dissipated by the reinforcement groove 43 and the reinforcement pipe 45 housed and adhered therein.

The present invention described above has a number of technical effects by using the main part of the wing body by replacing the conventional steel plate with fiber reinforced plastic and using the electric cylinder in the hydraulic cylinder of the wing as follows.

First: the production cost is low. The wing body of the present invention is cheaper than the wing body using the iron plate and the hydraulic cylinder on the basis of the 5-ton van, and the manufacturing cost is at least 30% to 50%. In the case of the present invention, the wing body parts can be standardized by molding the fiber reinforced plastic, so that the mass production is possible, and the manufacturing cost can be greatly reduced by using the electric chamber cylinder in place of the expensive hydraulic cylinder.

Secondly, the wing body manufacturing period can be greatly shortened by providing a method of assembling the preformed wing and door without riveting the steel plate when manufacturing the wing. Specifically, in the case of manufacturing a conventional wing body, at least five people including highly skilled technicians had to work for at least five days to complete the work. In the present design, three workers with inexperienced and common sense assembly techniques Wing body can be assembled up to 2 days by itself.

Third, the total weight of the van can be reduced. Wing body using the iron plate is the weight of the wing body only about 980Kg on the basis of 5 tons, but in the case of the present design is about 680Kg, there is a weight reduction effect of about 300Kg.

Fourth: Wing body strength and durability can be increased. The present invention provides the strength and the strength of the wing body by forming the reinforcing grooves integrally with the fiber-reinforced plastic panels when forming all the parts molded from the fiber-reinforced plastics, namely, the left and right wings, the side doors, and the rear doors. Durability can be increased by at least 2 to 3 times compared to the iron wing body. By improving the strength and durability of the wing body in this way, it is not easily damaged by external impact and is not crushed by the contact of the internal cargo. Therefore, the wing body according to the present invention can significantly increase the service life of at least five years.

Fifth: Liquids such as rainwater can be prevented from seeping into the wing body. In the case of a wing body using a conventional iron plate, the riveted portion may generate a gap due to vibration, and rainwater may leak into this gap portion, and rainwater may leak due to a structural defect of the ceiling portion in which two wings are coupled. However, the present invention can completely block the cause of leakage from the outside, in particular from the top of the wing body by improving the structure, such as by forming the wing itself integrally block the gap generation and install a rain gutter on the part where the two wings are coupled.
