Abstract

PROBLEM TO BE SOLVED: To easily shift and store a heavy object in a place provided with no cargo loading/unloading equipment or by means of a truck by dispensing with a transferring work, which deteriorates workability in a conventional heavy object shifting method, from a conveying vehicle to a workbench used in machining. SOLUTION: In hooking work, a required plural number of liftable workbenches with wheels necessary for work and a single workbench lifter, which is operated by an electric motor or an elevating cylinder and provided with an elevating mechanism having rolling wheels, are arranged and used in combination with each other, and a plurality of workbenches can be shifted and moved upward/downward by means of the single lifter, so that workability can be improved and storage can be simplified.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method in which a wooden pallet, which is normally used for loading and unloading heavy goods from a truck bed, is replaced with a wooden pallet instead of a forklift. And lower the other lifting platform and the lifting platform conveyed by the platform lifter.After lowering, transport the heavy goods in the factory with the lifting platform and raise it. Can be used as a work table as it is. Even if the workbench is stacked and stored without using it as a workbench, attaching a stud-like attachment can save space while keeping the goods on the workbench.

[0002]

2. Description of the Related Art Conventionally, a work table of this type is provided with a lifting device installed on each work table, and a load device for loading and unloading heavy goods from a truck is installed at the rear of the truck. Folding elevator is provided.
Further, a device described in JP-A-6-239598, which is partially similar to the present invention, has been proposed.

[0003]

[Problems to be Solved by the Invention] Transportation of heavy goods in a workplace using a carrier or a crane, transshipment from a carrier to a workbench, transportation and transfer of heavy goods in a workplace without crane facilities, other workplaces Simplifies the task of reloading heavy goods on wooden pallets carried by truck from trucks and reloading trucks at workplaces without forklifts.
In addition, cost reduction can be achieved by also using the lifting and lowering drive device, and these heavy objects can be stored in a small space.

[0004]

SUMMARY OF THE INVENTION The present invention relates to a workplace without crane equipment or a forklift, which uses an independent lifting / lowering drive device with moving wheels and a plurality of lifting / lowering worktables with moving wheels. It is intended to solve the problems of transportation, transshipment from trucks, and storage in the workplace.

[Embodiment] The following description is based on the drawings. Fig. 1-1
a is a side view when the lifting platform with moving wheels is lifted to the working position, FIG. 1-1b shows the front view, and FIG. 1-2a is a convenient position for transporting the lifting platform with moving wheels. FIG. 1-2b shows the front view of FIG. 1-2a, and a pair of right and left X-links 3 that rotatably connect an intermediate portion by a bogie 1 and a shaft 2 in FIG. , 4 and a work plate 5 mounted on the chassis 1 so as to be able to move up and down via the X links 3, 4. One end is rotatably connected, and a pair of rails 8 and 9 are installed on the left and right sides of the carriage 1 and the work plate 5 on the left and right sides.
Is installed, and the shaft 10-1 is rotatably fitted.
Lock blocks 12 are fitted at both ends of the rail 9 so as to be slidable inside the rail 9, and a shaft 11-
The rotating wheel 11-2 is rotatably fitted at both ends of the rail 1 and can freely roll inside the rail 8, so that the work plate 5 can be raised and lowered in a horizontal state. Wheels 21 capable of moving are mounted on the chassis 1.
1 to 6a or FIG. 1-1b, the mounting height can be changed in accordance with the use scene of the lifting / lowering work table with movable wheels.

Further, the rail 9 of FIG. 1-1a is provided with a descent lock mechanism of the work plate 5 shown in FIGS. 1-3a, 1-3b, and 1-3c therein. 3a,
Figures b and c show cross-sections sequentially from the center of the worktable to the outside. Lock block 1 that slides in rail 9
The ratchet 1 is fixed to the rail 9 shown in FIG.
5 locks the descent of the work plate 5. This means that when the work board 5 is lifted, it can be lifted freely, but in the case of descent, the descent is locked by the claw.

As a mechanism for releasing the lock, when the claw lifting plate 16 shown in FIG. 1-3B is slid by pushing the push button 20 shown in FIG. 1-4A, the claw 13 is raised by the cutting cam and the cam pin 17 of the claw lifting plate 16. The pin 14 attached to the work board is flipped up and the lock of the claw 13 and the ratchet 15 is released, and the work plate 5 can be lowered. However, in order to push the push button 20 of FIG. 1-4A and slide the claw lifting plate 16, the angle bar 18 is used for the workbench lifter / hook holder 1.
It is necessary to push up according to 9. In addition, the nail 13
The relationship between the pin 14 and the fry plate 16 is shown in a side view 1-3a-
a, 1-3b-b and 1-3c-c. The lifting of the workbench lifter / hook receiving member 19 is performed by the hook 31 of the workbench lifter with the moving mechanism with the moving wheel shown in FIG.
The lock must not be released even if the push button 20 is pushed in unless the safety of the descent is secured by the workbench lifter because it must be pushed up according to -a, b.

[0008] As shown in FIG. 1-5, the liftable worktable with movable wheels is sequentially stacked by covering the spacer attachment frame 24, and at the same time, works on the side rails installed on the upper part of the spacer attachment frame 24. Prevents the table from falling, and by changing the height of the spacer attachment frame, it is possible to store products and materials inside.

[0009] As shown in Fig. 1-6a, the worktable with a movable wheel is narrow, and the mounting position of the wheels 21 is lowered, and the worktable with a movable wheel is further mounted on a carriage 5 with a movable wheel. It is possible to raise and lower the workbench at a high place as shown in Fig. 1-6b.

[0010] Fig. 2-3a shows a side surface of a workbench lifter with a lifting mechanism with moving wheels, and Fig. 2-1b also shows a front view. The workbench lifter is composed of a vehicle body having a support 37 on an axle 42 and wheels 50, a well-known gear reducer 41 and a free caster 51, and a roller chain 34 rotating between left and right supports 37 by upper and lower sprockets 33 and 39. Roller chain is numbered 31-a in the figure,
One hook indicated by 31-b is attached. The hook is guided by four upper and lower rollers 31-e that roll inside the column 37, and is driven by the forward and reverse rotation of the power source connected to the gear reducer 41. The number 31-a in the figure indicates the upper limit position, and the number 31-b in the figure indicates the lower limit position.
As a power source for driving the lifting mechanism, a known electric motor may be used, but in the figure, a commercially available electric drill 30 is proposed, which is frequently used in each workplace. The electric drill 30 can be used for raising and lowering the worktable, which is advantageous in terms of cost and management.
If the connection tool is chucked at the tip of, and it is set on the holder 40, it can be moved up and down. Further, a method of raising and lowering the hooks 31-a and 31-b by using the lifting cylinder can be easily configured. In order to raise and lower the worktable with movable wheels, the downward hook 32 is set on the downward hook receiver 23 of the liftable worktable shown in FIGS. 1-2a and 1-1a as shown in FIG. 2-4. , Hooks 31-a or 31-
Workbench lifter for lifting platform with moving wheels at position b.
It is set on the hook holder 19, and the power source for driving the elevating mechanism is raised or lowered by rotating the power source in the upward or downward direction.

【The invention's effect】

As shown in FIGS. 1-5, 1-6b, and 1-7, unloading and unloading from trucks, ascending to a working position after safe transportation in a work place, reverse travel, and space saving. Fig. 2
As shown in -5, it is also possible to load the workbench lifter onto the truck by attaching the hook 31-a of the workbench lifter with the lifting mechanism with moving wheels in the opposite direction, and to simplify the movement and use it for work at the destination. .
