Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention proposes a scaffolding table apparatus suspended in a plant structure (10). But are not necessarily limited to, an overhead modular workbench for mounting a hanging scaffolding footplate (12) for an offshore plant. In particular, hanging hanging workbenches are preferred for the underside of the non-deck portion of the plant structure 10. FIG. 1 illustrates a state in which a rod-shaped support 15 is installed on the top layer of the plant structure 10.

According to the present invention, the main body 20 is constituted by the upper platform 21 and the lower platform 22, and has a fixing table 25 for suspension. The upper platform 21 and the lower platform 22 are formed to have approximately the same size and are always vertically spaced and opposed to maintain parallelism. The upper platform 21 and the lower platform 22 are applicable to a structure in which a plate material is detachably coupled to a frame. 2 illustrates a state in which a fixing table 25 of a cross section of a cross section is attached to both ends of the upper platform 21 so as to be engageable with the support table 15 described above.

According to the present invention, the folding means (30) is a structure that allows the height of the main body (20) to be changed by connecting the upper platform (21) and the lower platform (22) with the folding link (31). The folding means 30 realizes articulation motion of the folding link 31 connecting the upper platform 21 and the lower platform 22 and changes the gap facing up and down. If the distance between the upper platform 21 and the lower platform 22 is changed, the overall height variation of the main body 20 is accompanied. As described later, the folding link 31 may be composed of an upper link and a lower link.

The folding means 30 connects the upper link to the end hinge 23 attached to the upper platform 21 and attaches the lower link 22 to the end hinge 23 attached to the lower platform 22. [ And the upper link and the lower link are connected to each other by an intermediate hinge (33). 2, the upper link is connected to the bottom surface of the upper platform 21 by one side end hinge 23, and the lower link is connected to the upper surface of the lower platform 22 by the other side end hinge 23. [ The intermediate hinge 33 connecting the upper link and the lower link on both sides is configured in conjunction with a later-described rail link 32 to approach or move away from each other at the same time. In the process of reducing the height of the main body 20, the upper link and the lower link on the left side are bent to the right toward the center, and the upper link and the lower link on the right are bent to the left toward the center, .

The upper platform 21 and the lower platform 22 of the main body 20 are provided with the hatch 26 so as to be movable by utilizing the upper link and the lower link as a ladder. As shown in FIGS. 2 and 3, the lower link and the upper link include a plurality of horizontal members arranged at regular intervals, and serve as ladders. A supplementary member (not shown) may be additionally provided to serve as a ladder even when the lower link and the upper link are slightly bent. The hatch 26 disposed vertically at the same position in the upper platform 21 and the lower platform 22 is configured to be openable and closable so as to serve as a passage for the worker and the material.

The folding means 30 is knitted in a lattice pattern using a plurality of bar materials 35 and a pipe 36 to form a railing link 25 between the upper platform 21 and the lower platform 22. [ 32). FIG. 2 illustrates a state in which the rail link 32 is provided between the lower links, which are constructed in a lattice shape to prevent an operator from falling, and which is the folding means 30. The reason why the folding means 30 is composed of the bar 35 and the pipe 36 is to cause the length of the folding means 30 to be changed in accordance with the folding.

In this case, the railway link 32 is provided in a male and female sliding structure of the bar 35 and the pipe 36, and a cutting groove 37 is formed in the pipe 36 so as to be folded in cooperation with the folding means 30 . FIG. 4 illustrates a state in which a total of four members (links) are connected horizontally and vertically to form a railway link 32. The horizontal link connects the bar 35 and the tube 36 in a sliding structure, while the vertical link can be formed only by the bar 35 and the connecting pin 38 at the intersection. At least a part of the connecting pins 38 are provided on the cutting grooves 37 of the tube 36 so as to prevent mechanical restraint in the process of folding the rail link 32 in cooperation with the upper and lower links of the folding means 30. [ do. The cutout groove 37 is a slotted structure cut along the center line in the tube 36 at a predetermined length.

According to the present invention, the operating means 40 acts to apply a driving force of the winch 46 between the upper platform 21 and the lower platform 22 to cause a height variation. When the upper platform 21 is fixed to the plant structure 10, the actuating means 40 varies the height of the lower platform 22 corresponding to the upper platform 21. When the winch 46 of the operation means 40 is operated, the up and down movement of the lower platform 22 is caused through the wire 44 to be described later. 2 shows a state in which the winch 46 is installed on the upper surface of the upper platform 21, but it may be provided on the lower surface of the upper platform 21 as well. In addition, the actuating means 40 includes a controller 48 so as to be operable remotely by wire or wireless.

As a detailed construction of the present invention, the operating means 40 is characterized in that one side and the other side of the wire 44 are connected to the winch 46 via a sheave 42 of independent path. 5 (a) shows a process in which the height of the main body 20 is maximized when the height of the main body 20 is minimized. Fig. 5 (b) ) Is operated by the winch 46. The winch 46 shown in Fig. It is effective to prevent the platform 21 (22) from tilting in the process of folding and unfolding the main body (20) because the two wires (44) are wound around the winch (46)

The main body 20 includes a stopper 27 for maintaining a minimum height of the upper platform 21 and the lower platform 22, a latch 28 for forming a multi-layer scaffold extending vertically, And a control unit. 2, the stopper 27 is installed in the vicinity of the end hinge 23 of the lower link of the folding link 31. As shown in Fig. Therefore, when the size of the main body 20 is reduced, a minimum clearance is maintained at a height ensured. In Fig. 2, the latch 28 is installed at the corner of the lower platform 22. Fig. Thus, when the main body 20 is connected in multiple layers as shown in Fig. 1, the latch 28 is engaged with the holding table 25. In the case where the upper platform 21 and the lower platform 22 have a structure in which the plate members are coupled to each other on the frame, the plate of the lower platform 22 may be omitted for the overall weight reduction.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention. It is therefore intended that such variations and modifications fall within the scope of the appended claims.
