Description

Automatic cover device for cargo truck and its opening and closing method {The method and apparatus for carrying of automatic for dump cover}

The present invention relates to an automatic cover device for a cargo vehicle loading box and a method for opening and closing the same, and more particularly, to a loading box cover device for a cargo vehicle (commonly referred to as a "rolling-type cargo vehicle") for loading and unloading a cargo box. However, many studies have been conducted because the conventional luggage compartment cover devices cannot be used. However, in order to eliminate the inconvenience of having to attach the cover devices to each of the loading boxes, a single compartment cover device can be opened and closed. The present invention relates to an automatic cover opening and closing method of a cargo vehicle loading box and a method of opening and closing the same.

Falling rocks from dump trucks are damaging the road traffic as well as causing damage to nearby driving vehicles. This is caused by the problem of not binding or covering the cover thoroughly.

The lid of all conventional vans is packed with a support frame and a pavement supported by the pavement support bar and the bar, and since the loading box is fixed to the van, the switchgear is attached to the side of the van. The roll was a very simple configuration to open and close the loading box that secures the upper part of the truck deficit front.

When the cover is installed on the side of the van, the conventional cover has a large radius of rotation, which may cause a safety accident. The cover may be affected by surrounding features such as electric wires, and the cover may rotate in a wide radius so that the load applied to the rotating shaft is increased. Kerr has an uneconomical closure, which puts a significant load on the motor and requires an unnecessarily large motor.

Korean Utility Model Publication No. 97-49397 discloses a frame installed on the side of a dump box of a dump truck so that the frame is rotatably mounted so as to integrate a support rod on a pivot shaft and another wire connected to one end of the support rod. And a lid truck automatic cover configured to open and close the lid of the dump truck by controlling the rotation means so that the wire and the lid connected to the wire are wound or unwound as the support rod is rotated by connecting the lid connected to the lid.

Korean Utility Model Publication No. 94-786 is a dump truck loading box characterized in that a tent is connected to a motor and an air cylinder machined outside the loading box, and a switch is installed inside the driver's seat to open and close the loading box by operating a switch. It's about the automatic turn film cover

The Korean Utility Model Publication No. 97-1092 uses hydraulic or electric power of the vehicle itself to connect hydraulic and electric motors to the cover line reel shaft, and then connects the lines attached to the cover and roller to the holes in the separators. The present invention relates to a vehicle loading box automatic cover opening and closing device, characterized in that the loading box is opened and closed in the driver's seat by automatically winding and releasing action along the cover support groove by rotation and reverse rotation or stop of the electric motor.

The prior art relates to the opening and closing device of the loading box cover of the cargo vehicle used for the fixed cargo vehicle, there has been a problem that can not be used as a cover of the (loading) cargo vehicle is loaded and unloaded.

In order to solve the above problems, the present invention relates to a storage box cover device of a cargo vehicle (commonly referred to as a "rolling type cargo vehicle") for loading and unloading the cargo box, the both sides of the rear of the base of the cargo box is placed (that is, the chassis ) A support rod, a cover winding portion and a cover support rod consisting of a drum and a motor rolling the cover between the driver's seat and the storage box, and a drum and cover support rod winding the cover and springs provided at both ends of the support rod. The automatic cover of the cargo vehicle loading compartment that adjusts the height of the support bar according to the height of the loading box by the drum rotating the cover to open the loading box and turning the motor in the opposite direction to close the loading box while the drum releases the cover. It is a technical object of the present invention to provide an opening and closing device and a method for opening and closing the same.
