Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a transport vehicle for cardboard boxes, etc.

(Prior art) As shown in Fig. 6, this type of conventional transport vehicle is
Front and rear frames b and c are provided on the front and rear surfaces of the horizontal truck a, a side frame d is provided on one of the left and right sides, and an opening/closing door piece e is attached to the other open surface. Open the opening/closing door piece, place cargo such as cardboard boxes on the trolley, close the door, lock it, transport it to the required position, unlock it, open the door, and unload the cargo from the trolley. Ta.

(Problem to be solved by the invention) In this way, the conventional transport vehicle can load cargo,
The unloading work was extremely complicated.

The present invention was proposed in view of the problems of the prior art, and its purpose is to provide a transport vehicle that can easily load and unload cargo.

(Means for Solving the Problems) In order to achieve the above object, the transport vehicle according to the present invention has a structure in which the upper loading surface is located at the front edge of the vehicle between the front, rear, left and right columns each having wheels mounted on the lower end. A bottom plate formed on an inclined surface extending obliquely downward from the bottom plate to the rear end edge, and a U-shaped peripheral frame consisting of left and right side frames and a rear side frame arranged on the bottom plate. It is configured.

(Function) Since the transport vehicle according to the present invention is configured as described above, when cargo such as a cardboard box is loaded onto the upper loading surface of the bottom plate from the front open surface of the U-shaped peripheral frame, the same The cargo is oriented diagonally downward at the rear, and its rear surface is supported by the rear side frame of the surrounding frame. Therefore, the cargo does not fall from the front and back direction of the cart while the transport vehicle is moving, and Due to the left and right side frames of the peripheral frame, there is no risk of falling from the left and right sides of the cart.

After moving the transport vehicle to the designated position in this way,
The cargo on the bottom board is unloaded from the front open surface of the U-shaped peripheral frame.

(Example) The present invention will be described below with reference to the illustrated embodiments.

1 is a support frame for front, rear, left and right wheels 2;
A tubular support 4 is fitted onto the protrusion 3 that is more planted,
A tubular cover 5 is fitted to the lower end of the column 4, and a bolt 6 is inserted through the cover 5, the column 4, and the protrusion 3, and tightened with a nut 7.

Reference numeral A denotes a bottom plate, and the upper loading surface is formed as an inclined surface extending obliquely downward from the front edge to the rear edge, and a U-shaped peripheral wall 8 is erected across both left and right edges and the rear edge. ing. Furthermore, 4 on the front, back, left and right sides of the bottom board A.
A vertical cannula 9 is integrally provided at the corner, and each cannula 9
are fitted to the front, rear, left and right pillars 4 and are seated on the tubular cover 5.

B consists of left and right side frames 10 and a rear frame 11,
U-shaped peripheral frame with open front, left and right side frames 1
Cannula 12, 13 formed at the front edge and rear part of 0
are fitted to the front and rear columns 1, respectively.

In the figure, reference numeral 14 denotes a spacer interposed between the peripheral frame B and the peripheral wall 8 of the bottom plate A and fitted to the support column 4;
is a spacer fitted to the support column 4 at the upper part of the mantle tubes 12, 13 of the peripheral frame B.

A nut 16 is fitted to the upper end of the support 4, and a bolt 18 passes through the upper U-shaped frame 17 made of pipe.
The lower end of the nut 16 is screwed onto the nut 16. 19 in the diagram
20 is a rubber seat interposed between the upper U-shaped frame 17 and the spacer 15, and 20 is a cap fitted to the front end of the upper U-shaped frame 17.

Since the illustrated embodiment is configured as described above, the bottom plate A is
When the cardboard box C is loaded on top, the cardboard box C is tilted rearward and supported by the rear frame 11 of the surrounding frame B, as shown in FIG. However, there is no risk that the cardboard box C will fall from the front and rear directions of the transport vehicle. Furthermore, the left and right side frames 10 prevent the cardboard box C from falling from the sides of the carrier.

When the carrier is thus moved to a predetermined position, the cardboard box C is unloaded from the bottom plate A through the front opening of the U-shaped peripheral frame B.

(Effects of the invention) As described above, the transport vehicle according to the invention has a structure in which the upper loading surface of the bottom plate, which is installed between the front, rear, left, and right columns on which wheels are mounted at the lower end, is tilted from the front edge to the rear edge. By forming the peripheral frame, which is formed into an inclined surface extending downward and is mounted on the bottom plate over the respective pillars, into a U-shape with an open front surface, the front surface of the peripheral frame is open. It is now possible to load and unload cargo on the bottom panel from the bottom panel, eliminating the need to open, close, lock, and unlock the door piece installed on the transport vehicle each time, which is required in the past. This is significantly simplified, and at the same time, the cargo is held in a backwardly tilted state on the bottom plate during transportation, and there is no risk of it falling from the carrier.
