Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a movable workbench used in a work place such as a factory or a construction site.

(Problems to be solved by conventional techniques and devices) A movable workbench that has been conventionally used in a work place or the like has a third problem.
As shown in the figure, a combination of several sets of parallel links is used to elevate and lower the workbench by expanding and contracting the parallel links, as shown in FIG. 4, a workbench is moved up and down by a lift cylinder, and as shown in FIG. One that can raise and lower the workbench by changing the pressure in a plurality of hoses formed in the shape of a hose, or one that raises and lowers the workbench by using a drive device such as a winch as shown in FIG. was there.

However, in any of the above worktables, it is heavy and inconvenient to handle such as transportation, the scale of the main body is large and the number of parts is large, and it takes time to assemble the work place. There were some drawbacks, such as the difficulty of smooth movement in the field after assembly and the difficulty of using it. This invention solves the above drawbacks.

(Means for Solving the Problems) A base with movable means such as wheels and rollers, a ring-shaped spring body whose one end is fixed to the base, and a multistage hydraulic system in which one end is similarly fixed to the base. Jack, workbench fixing the other end of the spring body and the multi-stage hydraulic jack,
A movable workbench composed of a freely attachable handrail surrounding the outer periphery of the workbench and an operation panel arranged on the workbench for controlling the expansion and contraction of the multistage hydraulic jack.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a view showing the entire movable workbench 1 of the present invention. The movable workbench 1 includes a base 2 with movable means and a base 2
A ring-shaped spring body 3 whose one end is fixed, a multistage hydraulic jack 4 whose one end is similarly fixed to the base 2, and the other end of the spring body 3 and the multistage hydraulic jack 4 fixed It is composed of a working table 5, a handrail 6 attached around the outside of the working table 5, and an operation panel 7 for controlling expansion and contraction of the multistage hydraulic jack. Movable means 8 such as wheels and rollers are attached to the grounding surface side of the base 2 so that it can be freely moved to a necessary place. Since a load is applied to the movable means 8 from above, four or more movable means 8 are desirable in order to increase stability. A stopper is formed to prevent movement during work. One of the ring-shaped spring bodies 3 is fixed to the base 2 and is in a compressed state as shown in FIG. 2 when not in use, but when used it extends to an appropriate height as shown in FIG. Thus, the workbench 5 fixed to the multi-end side of the ring-shaped spring body 3 is stably supported.

Further, one end of a multi-stage hydraulic jack 4 is fixed to the base 2 to raise and lower the workbench 5. The multi-stage hydraulic jack 4 may be mounted at any suitable position, but it is preferably symmetrically arranged on the peripheral side surfaces of the base 2 and the workbench 5 as in this embodiment. The lifting control of the multi-stage hydraulic jack 4 and the control of the stopper are performed on the workbench 5.
The operation is performed by using the operation panel 7 on the workbench 5 so that a person working on it can easily operate. The operation panel 7 may be attached to the handrail 6 as long as it is connected to the multistage hydraulic jack 4 and the movable means by a cord, or it may be a hand type so that an operator can operate it independently. There is also a safety device in case the multi-stage hydraulic jack fails. Since the workbench 5 is to be ridden by a worker, the workbench 5 must have sufficient strength to withstand it, and at the same time, to move the movable workbench 1 in a compact state as shown in FIG. The handrail 6 is detachably attached to and attached to the periphery of the handrail 6 so that the handrail 6 can be removed. As the mounting means, an appropriate method such as a fitting method, a magnet method, or a screwing method can be considered.

(Effect of the Invention) The movable workbench 1 of the present invention having the above-described structure includes the upper and lower bases 2, the workbench 5, and the ring-shaped spring body 3, the multistage hydraulic jack 4, and the removable handrail 6 that connect them. Since it is made up of two parts, it is much lighter in weight than the conventional one, and can be easily transported and moved to a predetermined place.

Further, the moving means 8 such as wheels and rollers formed on the bottom surface side of the base 2 can easily perform the movement after the assembly. Moreover, since the fixed state of the movable work table 1 can be easily secured by the stopper, the worker can safely perform the work. Furthermore, since the movable workbench 1 only needs to be attached with handrails, on-site assembly work is extremely easy and simple.

Further, since the operator can move the multistage hydraulic jack 4 up and down by operating the work table 5, it is possible to easily adjust the work table up and down. Further, since the ring-shaped spring body 3 is formed, the work table 5 can be stably moved up and down, and work on the work table 5 is held from the lower periphery thereof. It became possible to do it safely and stably.
