Description

CARGO TRANSPORT VEHICLE HAVING EJECTOR DEVICE

The present invention relates to a vehicle for transporting cargo having an ejector device, and more particularly, to a vehicle for transporting cargo having an ejector device that is implemented so that a load loaded in a loading box of a cargo vehicle can be easily discharged without a dump of the loading box. it's about

In general, a dump truck refers to a special cargo vehicle for transport that automatically lowers loads such as soil and aggregate by tilting the loading box by 60 to 70° with power, and is also called a dump car.

Dump trucks are suitable for long-distance transport because they have good mobility compared to other transport machines, and are suitable for transporting soil, sand, and gravel. There are various loading capacities, such as 2-50 tons. The incline of the stowage is usually hydraulically actuated, but there are also mechanical and manual versions.

The dump truck was initially manufactured and used as a heavy machine for construction, but due to the advantage of its own unloading function, it is also used for cargo transport in addition to construction.

Dump trucks are classified into four types: side dump trucks, rear dump trucks, 3-way open dump trucks, and bottom dump trucks according to the inclination direction of the loading box. The side dump truck is a structure in which the side of the load box is attached to the chassis so that the load box can be tilted sideways. The rear dump truck is most used as a truck with a structure in which the rear of the loading box is attached to the chassis and the loading box can be tilted to the rear. The 3-way open dump truck is a truck with a structure that can tilt the load box to either side or rear. In addition, the bottom dump truck is a structure in which the bottom of the loading box is opened and the load can be loaded down, and is often used in trailer dump trucks.

However, the conventional dump truck for a dump truck raises the loading box to one side so that the load loaded in the loading box is unloaded. Therefore, the dump device of this configuration has a problem in that it is impossible to unload in a space with a low ceiling.

In addition, such a dump device has a problem in that a large amount of residual amount remains in the loading box when the loading material contains a lot of moisture or is wet.

In addition, if the ground of the dump truck having such a dump device is uneven or inclined at the place where the unloading is made, there may be a risk that a rollover accident may occur.

On the other hand, the above-mentioned background art is technical information that the inventor possessed for the derivation of the present invention or acquired in the process of derivation of the present invention, and it cannot be said that it is necessarily a known technique disclosed to the general public before the filing of the present invention. .

a housing installed on an upper surface of the seating space of the sliding frame opposite to an upper inclined surface of the sliding rail;
a guide roller rotatably connected to the housing and having an end exposed to the outside of the housing seated on an upper inclined surface of the sliding rail and rotating along the sliding rail; and
and a fastening part for fastening the housing to the sliding frame;
It is connected to the rear end of the housing part, and when the housing part moves along the bottom surface of the loading part according to the extension of the power part, the rear end of the loading part has a discharge port so as to reduce frictional force with the loads loaded in the loading part. It further includes; a friction force reducing cover that is formed so that the left and right width and vertical height are gradually reduced in the direction to cover the rear end of the power unit and connect and install;
The friction reducing cover portion,
The bottom surface forms a plane so that it can be seated on the upper side of the loading part, and forms a vertical surface so that one side and the other side are vertical and vertical, and the upper part is formed in a pentagonal shape formed in a "s" shape, the front end opening said After the rear end of the housing portion is seated, the lower one side and the other side of the rear end of the housing portion are connected and installed so as to be rotatable, and the cover body is formed such that the left and right width and the vertical height are gradually reduced toward the rear end direction;
a main body cover installed to cover between the front end opening of the cover body and an outer surface of the housing part to prevent foreign substances from being introduced into the cover body;
a triangular pedestal formed in a triangular shape forming an upper inclined surface corresponding to the upper inclined surface of the cover body and installed on the bottom surface of the cover body, the left and right widths and vertical heights gradually decreasing toward the rear end;
A first cover support provided along the spaced space between the one inclined surface of the triangular pedestal and the upper one inclined surface of the cover body to attenuate vibration or shock generated between the cover body and the load according to the movement of the cover body;
A second cover installed along the separation space between the other inclined surface of the triangular pedestal and the other upper inclined surface of the cover body to attenuate vibration or shock generated between the cover body and the load according to the movement of the cover body support fixture; and
Including; and a plurality of reinforcing plates spaced apart from each other in the longitudinal direction along the inner upper corner of the cover body so as to reinforce the upper corner of the cover body.
The first cover support portion,
a support plate for supporting an inclined surface of an upper side of the cover body;
a buffer part installed at regular intervals along the lower side of the support plate to support the support plate so as to buffer the shock transmitted from the support plate; and
It includes; a buffer case that is seated on one inclined surface of the triangular pedestal, and each lower portion of the buffer is inserted through the upper side and installed inside.
The buffer unit,
a support plate installed under the support plate;
a support bar extending in a vertical and longitudinal direction, the upper part being rotatably connected to the lower part of the support plate to support the support plate, and the lower part being inserted into the inner space of the buffer case;
It is formed in a rectangular tube shape and installed inside the buffer case in an upright state to support the gap between the inner ceiling surface and the bottom surface of the buffer case, and an inner in which the lower part of the support bar is seated in the inner space. square tube;
It is formed in the shape of a square plate corresponding to the inner shape of the inner square tube, and a plurality of them are installed to be spaced apart from each other in the vertical direction along the inner side of the inner square tube. Horizontal bulkheads formed through;
an intermediate node provided in each lower portion of the support bar opposite to the upper and lower through-holes and formed in a cylindrical shape corresponding to the shape of the upper and lower through-holes; and
It includes; a bar support elastic body installed on each inner wall of the inner tube, each side of which is fastened to the lower portion of the support bar to support the lower portion of the support bar by using elastic force;
The support bar,
an upper bar rotatably connected to a lower portion of the support plate;
a lower bar having a lower portion inserted into the inner space of the buffer case; and
and a bearing for connecting and installing the upper bar and the lower bar to be rotatably connected to each other.
