Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Utilization Public Expenditure) The invention relates to a luggage compartment securing device in a transport vehicle.

(Conventional Technique W) Conventionally, the luggage compartment of a transport vehicle for loading products (bottle cases for bottles, cans, etc.) is fixed on the chassis frame, and since the products are unloaded by hand, it is difficult for workers to unload the products. It was hard work.

Therefore, in recent years, transportation vehicles with a cargo compartment that can be moved up and down have been proposed in order to improve the efficiency of loading and unloading products.

However, in this type of transport vehicle, there are eight problems in that the cargo compartment must be securely fixed on the chassis frame because it is dangerous if the cargo compartment falls for some reason while the vehicle is running and comes into contact with the ground.

(Means for Solving the Problems) The present invention has been made in view of the above-mentioned problems, and a hook member that can be freely engaged and detached from a locking piece provided in the liftable cargo compartment is attached to a frame on a vehicle chassis frame. The flap member is pivotally supported to be able to swing freely, and the flap member is connected to a driving means.

(Function) The non-invention is to rotate the hook member by operating the drive means and 1.
By engaging this hook member with the locking piece of the luggage compartment, the luggage compartment is reliably fixed to the chassis frame during traveling.

(Embodiment) Hereinafter, an embodiment of the invention will be explained based on the drawings.The transport vehicle 1 is behind the driver's cab 2! It is a bread type with a cargo compartment 6 in the wall, and specifically, it is a product 21... (see Figure 4) such as bottles or cans filled with soft drinks, milk, beer, alcohol, etc. This vehicle transports bottle cases containing .

The cargo compartment 6 includes six cargo compartments 5a arranged symmetrically.

5b, 5o, etc., and an opening/closing shutter (not shown) is provided on the side of each cargo compartment. The chassis frame 7 on which the cargo compartment 6 is mounted has a structure that is disposed at the center in the width direction of the vehicle body, and specifically, the
A bone frame is used. The front luggage compartment 5a is located in the space on both sides of the chassis frame 7.
, 5a and the rear luggage compartments 5o, 5a's loading platform 8, etc. can be raised and lowered, while the central luggage g5b, 5b's loading platform 10, 10 located above the rear wheels 9, 9 is fixed. The structure is said to be

The mounting structure of the liftable cargo platform 8 is shown in FIGS. 6 to 4. Supports 11 and 11 are erected upright on the chassis frame 7, and the guide member 12 can be moved up and down along these supports. The loading platform 8 is provided at the lower end of the guide member 12.

The lower end of the pillar 11 is fixed to the chassis frame 7, and its upper end is fixed to the ceiling of the cargo compartment 6. The spacing between both pillars 11.11 is 5m, 5a for the front and rear luggage compartments.
is set accordingly.

Further, each of the pillars 11#/c is provided with two guide rollers 14 for guiding the guide member 12.

The guide member 12 is formed by framing frame members 15, 16, . Functions as a rail. That is, the guide rollers 14 of the support columns 11, 11 are rotatably engaged with the vertical frame members 15, 15, so that the guide member 12 is engaged with the guide rollers 1.
4... It is possible to go up and down. The left and right guide members 12, 12 are connected by a connecting member 18 so as to move up and down in an integrated manner, and the connecting member 18 is connected to hydraulic cylinders 19a, 19alC whose base ends are attached to the chassis frame 7. has been done.

The cargo platform 8 has a floor surface of 5m and 5a in the front and rear cargo compartments, has a rectangular flat plate shape, and is provided at the lower end of the guide member 12 in a substantially horizontal manner toward the side of the unit. ing.

That is, the distal end of the loading platform 8 is attached laterally so as to be slightly higher than the proximal end fixed to the guide member 12.

20.20 is a reinforcing material.

Thus, the luggage compartment 5a is configured as described above.

5c is moved up and down by hydraulic cylinders 19a, 19a while being guided by guide rollers 14, .

Next, the lashing devices for the cargo compartments 5a and 5o will be explained. A hook member 22 is connected to the bracket 21 fixed to the frame of the central ceiling of the cargo compartments 5a and 5o at a pivot point. Bell crank 2 pivotally connected to the front ceiling of chamber 6
The hook member 22 is connected to 6 via a rod 24 and a spring cylinder 25, respectively. Furthermore, the tip of a hydraulic cylinder 26 (driving means) whose base end is connected to the upper part of the support column 11 is connected to the bell crank 23.
When the hydraulic cylinder 26 is extended or contracted, the 7° angle member 22 swings back and forth and engages and disengages from the locking piece 27 that connects the upper portions of the guide members 12, 12.

It should be noted that compression springs 28 and 29 are built into the spring tube 25, as shown in FIG.

Next, the hydraulic circuit of the transport vehicle 1 according to the present invention will be explained.
Electric motor M1 Hydraulic pump P1 which is directly connected to this rotating shaft. Power unit and Toro 0 are composed of an oil reservoir that communicates with the suction boat of this pump P and electromagnetic pulp Vl and V2 that communicate in parallel with the discharge boat of this pump P. However, this power unit y 50 Oa boat has a hydraulic cylinder 19a,
19atlc communication, power uni, toro 0 nosu, o
The boat communicates with the hydraulic cylinder 26, and the boat that communicates with the oil reservoir TK is further communicated with the electromagnetic switching valve v3.

Next, we will explain the steps for transporting the product 21... of the transport vehicle 1. ■ Drive the power unit 60 and operate the electromagnetic switching valve vg.
When the hydraulic cylinder 26 is switched to the right position, the hydraulic cylinder 26 is retracted. During this time, since the hook member 22 and the locking piece 27 are engaged, the movement of the rod 24 is absorbed by the spring @25. After returning the electromagnetic switching valve v2 to the neutral position, the electromagnetic switching valve v1 is When the electromagnetic switching valve v3 is switched to the right position and the electromagnetic switching valve v3 is switched to the left position, the hydraulic cylinder 19a of the front cargo space 5a is extended and the cargo platform 8 is raised.

■ When the engagement between the hook member 22 and the locking piece 27 is released, the rod 24 is pulled by the compression spring 29 of the spring tube 25, and the rod 22 swings in the previous direction (clockwise direction). Then, it is reliably released from the locking piece 27.

■ Next, when the above electromagnetic switching valve v1 is switched to the left position,
Only the ifg luggage compartments 5a, 5a can be lowered at the same time.

■ The loading platform 8 is grounded, and the bottle cases 21,...
・Can be easily destroyed.

■ When the on-machine ε electromagnetic switching valve v1 is switched to the left, the hydraulic cylinder 9a extends and the front cargo space rises by 5°, 5°, and then the electromagnetic switching valve V2.

When switched to the right, the hydraulic cylinder 26 is extended and the hook member 22 and the locking piece 27 are engaged to close the front luggage compartments 5a, 5.
a is securely fixed.

■ - 10,000, To raise and lower the loading platform 8 of the rear luggage compartments 5a and 5o, you can do the same as above except for switching the electromagnetic switching valve v3 to the right position.In addition, in the embodiment of the present invention, the loading platform 8 of the rear luggage compartments 5a and 5o There are two sets of cargo compartments that can be raised and lowered, with one set of cargo compartments.
As another embodiment, there may be two or more sets of luggage compartments, and the luggage compartments on both the left and right sides may be raised and lowered at the same time, or as another embodiment, the luggage compartments on both left and right sides may be raised and lowered separately. good.

(Effects of the Invention) As described above, according to the present invention, since the driving means can swing the member by 7 degrees, the luggage compartment can be reliably fixed to the chassis frame during traveling.
