Abstract

PROBLEM TO BE SOLVED: To provide a ramp way function and a lifter function at the same time so as to improve maneuverability by allowing inclination of a movable deck mounted on a freely movable running body so that its rear end can be grounded and allowing elevation of the movable deck so that its front end can be connected to the rear end of a fixed deck. SOLUTION: A movable deck 1 mounted on a running body 10 can be moved to the optional height when both of its front and rear ends are elevated/lowered at the same time. If only the front end is elevated/lowered, a slope can be formed in the longitudinal direction. In a fixed deck 2, which is fixed at the predetermined height, a deck board 2a is formed in the front half part. A driving force of a motor 5 arranged behind a driver seat 7 is transmitted to a front shaft 8 from a sprocket A via a chain and a sprocket B so as to drive left and right endless chains 4, 4' in the front part stood in the vertical direction upward/downward, and the front end of the movable deck 1 is connected to the chains 4, 4' via a link 1'.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rampway used for container / bandevan work at a work site without cargo handling at a port or a platform.

[0002]

2. Description of the Related Art Many of the conventionally known rampways are of a stationary type, and the cargo handling work place is limited to a certain place, and long cargoes such as long heavy objects having a large shape of the cargo are difficult to perform bandevan work with the rampway. When handling an object, for example,
When loading and unloading vehicles that have difficulty in climbing and descending slopes such as low lifts for containers with long forks, there is no choice but to use the platform or remove the container from the trailer. . Therefore, there are problems that the equipment becomes large-scale and that additional work is required.

As a means for avoiding this problem, a large table lifter or a deck board in which a pedestal part is lifted or tilted is known (Japanese Patent Laid-Open Nos. 3-111399 and 3-128822, etc.). However, there is a problem in that maneuverability is limited at a predetermined position and mobility is poor.

[0004]

In view of the above problems, the present invention is provided with a traveling function so that the cargo handling place is not limited and can be moved, and the pedestal part can be tilted to be used as a rampway (slope). It is possible to use it as a lifter that can be vertically moved up and down while maintaining the horizontal state, and provides a general-purpose movable deck with good maneuverability that has both the traveling function, the rampway function and the lifter function. This was done as an issue.

[0005]

The present invention provides a means for solving the above problems, in which a movable deck 1 and a fixed deck 2 with a deck board 2a are mounted on a traveling body 10 which can travel freely. With the traveling function, the movable deck 1 can be tilted and its rear end can be grounded, and the movable deck 1 can be raised and lowered, and its front end and the rear end of the fixed deck 2 can be connected. A tiltable and vertically movable movable deck is the subject of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the drawings, reference numeral 1 denotes a movable deck which is mounted on a traveling body 10 and which can be freely raised and lowered and whose front and rear ends are simultaneously raised and lowered to an arbitrary height while maintaining a horizontal state. It can be moved, and an inclination in the front-rear direction, that is, a slope can be formed by raising and lowering only the front end.

A fixed deck 2 also mounted on the traveling body 10 is fixed at a predetermined height, and a deck board 2a is formed in the front half of the fixed deck to clear steps and gaps with cargo-handling goods such as containers. You can do it.

Reference numeral 3 is an electromagnetic clutch, and its ON / O
The FF allows the driving force of the motor 5 to the front lifting / lowering chain 4 of the movable deck 1 to be transmitted to the rear lifting / lowering chain 6 as well.

The driving force of a motor 5 installed behind the driver's seat 7 is transmitted from a sprocket A of its output shaft to a front shaft 8 through a chain and a sprocket B, and is mounted near both left and right ends of the shaft 8. Through the sprockets C and C ′, vertically driven left and right endless chains 4 and 4 ′ are vertically driven and connected to the chains 4 and 4 ′ via links 1 ′. Movable deck 1
Raise and lower the front end of. Incidentally, D and D'in the figure are upper sprockets for supporting the upper portions of the endless chains 4, 4 '.

The front shaft 8 is rotated by the sprocket B.
Is transmitted from the sprocket B ', which is coaxial with the sprocket B', to the entry side sprocket E of the electromagnetic clutch 3 via the chain, and when the clutch 3 is turned on, it is transmitted from the exit side sprocket F to the rear shaft 9 via the chain and sprocket G. .

Therefore, when the electromagnetic clutch 3 is off, the rotation of the sprocket E is not transmitted to the sprocket F and the rotation of the motor 5 is not transmitted to the rear shaft, but the electromagnetic clutch 3 is turned on to rotate the sprockets E, F.
By connecting the
It is transmitted to the rear shaft 9 via a sprocket G, and drives the right and left endless end chains 6, 6'standing vertically in the vertical direction via sprockets H and H'mounted on the left and right ends of the shaft 9, respectively. Then, the rear end of the movable deck 1 connected to the chains 6 and 6'can be moved up and down. In the figure, I and I ′ are upper sprockets for supporting the upper part of the endless chain 6.

Reference numeral 10a denotes an elevating guide of the movable deck 1 which also serves as a support of a frame mounted on the traveling body 10 and has a section U
The guide rails and the guide rollers each have a character shape, and serve to guide the movable deck 1 suspended in the chains 4 and 4'in the vertical direction while restricting the movement of the movable deck 1.

The diameter of the sprocket A of the output shaft of the motor 5 is arbitrary, but other transmission sprockets B, B'-I,
The diameters of I'are all the same, and synchronous rotation is maintained. Further, in the illustrated embodiment, the traveling body 10 is provided with the driver's cab 7 on the right side of the front part thereof to be self-propelled, but the self-propelled function may be omitted and the traveling body 10 may be towed by a towing vehicle.

Although the sprocket chain is used as the lifting drive means for the movable deck 1, a hydraulic cylinder, a link or any other drive means may be adopted.

According to the above-described embodiment, the rotation of the motor 5 is transmitted from the sprocket A to the chain and the sprocket B, the front shaft 8 rotates, and the left and right sprockets C and C'indicate the front left and right endless chains. 4, 4'actuate, and the front end of the movable deck 1 connected to the chains 4, 4'can be moved up and down.

The rotation of the sprocket B is transmitted from the coaxial sprocket B'to the entry side sprocket E of the electromagnetic clutch 3, but when the electromagnetic clutch 3 is turned off,
The rotation of the sprocket E is not transmitted to the sprocket F,
Since the rotation of the motor 5 is not transmitted to the rear shaft 9,
Only the front end of the movable deck 1 moves up and down.

Therefore, by raising the front end of the movable deck 1 from the state shown in FIG. 3 to the height of the fixed deck 2, as shown in FIG. The part can be connected to the fixed deck 2, and conversely, the state shown in FIG. 2 can be returned to the state shown in FIG. 3 by lowering the front end of the movable deck 1.

On the other hand, when the electromagnetic clutch 3 is turned on to connect the sprockets E and F, the rotation of the motor 5 is
It is also transmitted to the rear shaft 9 via the sprocket G,
Via the sprockets H and H ′ attached near the left and right ends of the shaft 9, the rear left and right endless chains 6 and 6 ′ which are vertically installed are driven to drive the chains 6 and 6.
The rear end of the movable deck 1 connected to 6'can be moved up and down.

Therefore, from the state shown in FIG.
As shown in FIG. 4, it can be connected to the fixed deck 2 while keeping the horizontal state by raising both the front and rear ends of the movable deck. On the contrary, the front and rear ends of the movable deck 1 can be lowered from the state of FIG. Can be returned to the state shown in FIG.
