Description
The present invention relates to a curtain type closed-type lid cover using a high-strength fiber sheet, and more particularly, to a lid cover of a curtain type using a high-strength fiber sheet, The present invention relates to a curtain type closed-type lid cover.
Generally, the loading box is installed at the rear of the car's car to load cargo.
Today, in Korea, where dump trucks are generalized, there is no enclosed trucks and formal tent carvers are used. As a result, fugitive dust and odors are generated at the time of driving the vehicle, causing serious environmental problems. There are many cases where roads are polluted and subsequent vehicles are subjected to traffic accidents.
In the case of vehicles transporting waste, many complaints arise due to scattered dust and odors generated from waste. The Ministry of Environment and others are trying various solutions to solve these problems, but there is no proper alternative.
In order to solve these problems, legislation is being made in order to shut down the loading boxes in Korea.
Generally, the loading box is provided with a cover (opening and closing door) for opening and closing the loading box. There have been many applications for a method of automatically opening and closing the cover.
As a method for opening and closing the lid, there is a method of opening and closing the lid in two directions with the center portion being divided in two directions, and a method of opening and closing the lid by moving the lids in a sliding manner.
As a method of folding and spreading the cover in two directions centering on the center portion in a manner that the cover is divided into two halves, there is a method in which the cover is divided into two halves by using a sprocket, a chain and a driving motor, But it can not prevent the scattered dust and odor from being generated because it is not completely sealed, it is easily damaged and lost its function due to lack of durability, and the cover material is a tent material, which tears easily and has a short life have.
Korean Patent No. 10-1068339 (entitled " automatic opening / closing device for a lid of a waste container ") discloses another example of a method in which the lid is folded in two directions and spreads in two directions around a central portion.
The lid automatic opening and closing apparatus has a structure in which a pair of lids hinged to both sides of the upper portion of the loading box body are opened and closed in both directions using a sprocket, a chain, and a cylinder.
The cover automatic opening and closing apparatus has a complicated structure because it uses a sprocket, a chain and a cylinder to open and close the pair of covers in both directions. In addition, the loading operation can not be performed in the lateral direction of the vehicle without fully opening the lid. Therefore, in order to make the cover located at one side of the vehicle to be loaded in a pair of covers to be completely opened, it is necessary to always secure a space of half the width of the loading width of the vehicle separately from the space for the loading operation, It is necessary to perform the above-mentioned process.
As a method of opening and closing by sliding the cover in a sliding manner, the Korean Utility Model Publication No. 20-1994-0007269 (entitled "Waste Carrying Cover Opening and Closing Device") has been disclosed.
The waste container lid opening / closing device is structured such that a roller is installed on the lid of the loading lid to be opened and closed step by step.
The waste container lid opening / closing device has a complicated structure because it has a rail and a roller for manually opening and closing the lid. Further, since the lid is formed in multiple stages, there is a problem that the operation is not smooth.
SUMMARY OF THE INVENTION The present invention has been conceived in order to solve the above problems, and it is an object of the present invention to provide a cargo cargo lid of a freight vehicle, which is made of a fiber sheet having excellent durability, And a curtain type closed type lid cover using a high strength fiber sheet to be sealed.
Another object of the present invention is to provide a curtain type closed-type lid using a high-strength fiber sheet which prevents the occurrence of deflection by maintaining the tension of a curtain-type cover made of a fiber sheet.
In order to accomplish the above object, the curtain type closed type lid of a high strength fiber sheet according to the present invention includes a first guide groove (11) coupled to an upper edge of a loading box (200) A pair of longitudinal frames (10) provided with a housing and a housing space formed therein; A
