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

The present invention proposes an apparatus for installing a hanging scaffold on an H beam of a deck. FIG. 1 illustrates a state where a multi-layered deck (DK) is provided in a marine plant composed of three stages of production modules (MD). In the method of the present invention, the conventional external scaffold 11 and internal scaffold 12 are reduced or eliminated. Utilizes but is not necessarily limited to a number of H beams 15 included in the deck.

On the other hand, in FIG. 1, reference numerals SF denote the positions of the footrests 25 to be applied to the scaffold of the present invention.

According to the present invention, a scaffolding module 20, which is formed in a multi-layer structure to reduce or replace the external scaffold 11, is installed adjacent to the side surface of the deck to assist movement of personnel and materials. The scaffolding module 20 may include a fixture bound to a deck or the like of an offshore structure, and a ladder for lifting and lowering the operator.

According to the present invention, the pole 30 is a structure having a means for engaging the top. The engaging means is associated with the fixing table 31 and the movable table 34 as will be described later. The fixing table 31 is preferably welded to the upper end of the pole 30, but may also be coupled in a spiral or fin structure so as to be detachable. The movable base 34 is formed to have a "?" -Magnetic cross-section so as to engage with the flange of the H beam 15, and at least a part of the movable base 34 is configured to be movable on the fixed base 31 for ease of detachment with respect to the H beam.

The above-mentioned means of the present invention is characterized in that the engaging means includes a pair of movable belts (34) movably mounted on a fixed base (31), and a center frame (36) Or the like. In FIG. 4, a pair of opposed movable bases 34 are moved to the guide grooves 32 formed in the fixing table 31 and are simultaneously accessible so as to surround the flange of the H beam. The guide grooves 32 are formed to have a constant length on the same straight line on both opposite sides of the fixing table 31. The movable base (34) has a guide block which is brought into close contact with the upper and lower sides of the fixed base (31) to prevent swing during movement. The movement for causing the clamping to approach the both side movable bands 34 is performed by the gripper 44 of the carriage 41 described later. The center bar (36) is engaged with a spiral on the fixing table (31) to change the rotational motion applied from the outside to the up / down motion to vary the pressing force against the H beam. As shown in FIG. 3, when the movable base 34 on both sides and the central center 36 on the center come into contact with the H beam at three points, the stable binding force of the pole 30 can be maintained.

According to the present invention, the driving means 40 moves to the H beam while holding the pole 30 in the carriage 41, and fixes the pole 30 to the H beam. The driving means 40 is based on a carriage 41 having a traveling wheel 42 and mounts a main component and a power source (battery), which will be described later, on the carriage 41. The carriage 41 moves with the clamping means clamped, but can optionally add clamping to a portion of the pole 30. The poles (30) are fixed at regular intervals on the H beam to support the footrest (25).

The driving means 40 of the present invention is characterized in that the driving means 40 is provided with a gripper 44 for causing the movable base 34 to move while gripping the fixed base 31 on the carriage 41 . 4 shows a state in which the "?" Shaped gripper 44 is engaged with the guide groove 32 of the fixing table 31 and clamped. The gripper 44 also clamps the fixing table 31 and simultaneously clamps the movable table 34 on both sides thereof. To do this, one of the grippers 44 is operated in two stages or two grippers are stacked. In any case, the gripper 44 is connected to a driver 46, which will be described later, to perform the turning motion.

The drive means 40 engages the driven gear 38 of the center belt 36 and drives the drive 46 and the drive gear 48 to move up and down the center belt 36. [ (41). The driver 46 causes clamping / unclamping of the side grippers 44 based on the motor. A worm gear having a deceleration and an anti-reverse function can be interposed between the gripper 44 and the driver 46. The driven gear 38 is formed on the outer peripheral surface of the center belt 36 and the drive gear 48 is mounted between the side grippers 44 in the carriage 41. [ The above-described driver 46 can also perform a function of applying a rotational force to the drive gear 48. [ The carriage 41 clamps the fixing table 31 of the engaging means and the driven gear 38 of the center table 36 is moved in a state of being meshed with the driving gear 48 as shown in Fig. Thus, when the drive gear 48 is rotated by the operation of the driver 46, vertical movement of the center belt 36 is caused.

According to the present invention, the control means (50) controls the movement of the carriage (41) and the fixing of the pole (30). It is possible to implement the repetitive work by the control means 50 to install the poles 30 at equal intervals on the specific H beams 15. [ The control means 50 realizes the automatic mode by the set program, but preferentially processes the manual mode by the operator's instruction.

The control means 50 includes a control portion 51 for storing and executing the set algorithm, a distance detecting portion 53 for detecting the position of the carriage 41 on the H beam, And a driving unit 55 for applying power to the wheel 42 and the driving unit 46. The control unit 51 is a microcomputer circuit having a microprocessor, a memory, and an input / output interface. The distance detecting unit 53 may use a laser sensor corresponding to a specific reference point including the footing module 20 in addition to the encoder for counting the number of rotations of the traveling wheel 42. [ The driving unit 55 converts the microcomputer output of the control unit 51 into a power source required for the traveling wheel 42 and the driving unit 46 and applies the converted power.

At this time, the control unit 51 preferably includes a remote controller 57 in order to increase the convenience of the operation.

As an example of the operation, a control section 51 is provided adjacent to the footing module 20, the carriage 41 is mounted on the H beam 15 to switch to a stand-by state for traveling, The gears 38 and 48 are engaged while the fixing table 31 is engaged with the gripper 44. The distance is confirmed while the carriage 41 is moved to a desired position and the carriage 41 is stopped, The carriage 41 is returned to the footing module 20 side and the next pole 30 is mounted in the same manner so that the clamping is completed by raising the center frame 36 while closing the both side movable blocks 34 do.

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 as defined by the appended claims. It is therefore intended that such variations and modifications fall within the scope of the appended claims.
