Field of the Invention The present invention relates to a lid unit, and more particularly, to a lid unit for a dump truck, which improves the structure of the lid unit, The present invention relates to a load-carrying lid unit for a dump truck, which improves durability and improves the rigidity of the lid unit so as to more safely carry and store loads in the luggage compartment.

In general, dump trucks transporting gravel, sand, and soil are used to prevent the cargo loaded on the cargo from falling on the road surface due to wind or vibration, causing damage to the road or causing other car safety accidents Cover the cover.

In addition, legislation has been enacted to mandate the installation of lid cover.

Here, the operator or the operator climbs the load on the load box of the truck and fixes the load with the rubber band or the like. The dependence of the cover on the operator's labor force not only deteriorates the driver's ability to operate but also consumes a considerable amount of time to cover the cover, and above all, the driver has fallen from the top of the cargo bay and caused damage.

In order to solve the above-mentioned problem, a cover device is mounted to open and close the open upper surface of the loading box.

A conventional automatic lid apparatus for a dump truck loader is mainly composed of a pair of lids each having an area corresponding to approximately half the size of the opened upper side of the luggage compartment and a lid provided on one side edge of the lid, And a drive motor connected to the drive shaft is attached to one end of the rotation support shaft. When the rotation support shaft is rotated in the forward or reverse direction, the cover is rotated to cover the upper surface of the loader (Open / close) so as to be able to roll.

However, when the drive motor is driven to open and close the lid, the conventional automatic lid apparatus for a dump truck loading unit configured as described above has a problem that rotational force is applied to the rear end portion of the support shaft remote from the drive shaft, It is transmitted weakly.

That is, a torsional moment is generated in the support shaft, and the cover is warped. When the lid is twisted as described above, there is a risk that the lid can be easily moved during the operation because the force of opening and closing the rear end is weak, and the load may fall.

In order to solve the above problems, Korean Utility Model Registration No. 20-0340096 discloses a "automatic lid for a dump truck loading box ".

Conventionally, Korean Utility Model Registration No. 20-0340096, "Automatic lid for a dump truck loading box" reduces the difference in rotational force according to the positions of the support shaft and lid, thereby opening and closing the lid with a relatively uniform rotational force, A pair of support shafts rotatably supported on both sides of the dump truck loading box, a pair of drive devices connected to one end of each of the support shafts and a drive shaft, A pair of lids which are rotated together with the supporting shafts to open and close the luggage compartment, respectively, by driving the respective driving devices; and a pair of lids, And a pair of anti-warp portions provided between the shafts.

Since the automatic lid device reduces the difference between the rotational force acting on the front portion of the lid and the rotational force acting on the rear portion of the lid, the lid is opened and closed with a relatively uniform force regardless of its position, so that an excessive torsional load acts on the support shaft, It is possible to prevent a distortion phenomenon of the display device.

A conventional truck lid apparatus is disclosed in Korean Patent No. 10-0654291 entitled " Truck Loader Lid System "and Korean Patent No. 10-1032768 entitled" Automatic Lid Opening and Closing System for a Dump Truck Loader ".

However, such conventional lid apparatuses have a problem that the degree of coverage of the left and right lid apparatuses is different and soil, sand, and other loads loaded on the luggage compartment are discharged to the outside, causing safety accidents.
