Abstract

The invention discloses a method for disassembling a marine scaffold device, which comprises the steps of welding a U-shaped frame between two scaffolds, disassembling a fixing nut between the scaffold at the outer end and the scaffold, and keeping a bolt still; one end of the rope is tied at the middle part of the scaffold, and the other end of the rope passes through the U-shaped frame and is held in the hands of the people who disassemble the scaffold; the disassembling person moves to a position between the two scaffolds without disassembling the nut, the pedal at the bottom is retracted, and the scaffold at the outer end is suspended; horizontal external force is applied to the unsettled scaffold through the cross rod for it breaks away from with the scaffold, and the person of disassembling holds rope cooperation U type frame and slowly puts down the scaffold to the bottom, accomplishes once and disintegrates. The invention can ensure the safety of operators below, simultaneously can not damage the lower structure or the paint surface, reduces the workload and improves the efficiency.

Description

Disassembling method of marine scaffold equipment

Technical Field

The invention relates to a method for disassembling a scaffold, in particular to a method for disassembling a marine scaffold, which is used for disassembling the scaffold at a special part of a ship.

Background

In marine production, often need weld or the application with the help of the scaffold equipment, in special construction department (like the anti-top of deck etc.), still need set up some and hang the scaffold and operate, this kind of scaffold is because of the condition restriction (like vertical height is too high, peripheral no structure foot etc.), need specific disintegration mode to ensure safety, if simple messenger's gravity free drop, not only lead to the fact the threat to the operating personnel of below, and free falling can lead to the fact the damage to below structure or paint face, thereby need later stage to repair, the cost is increased, the efficiency has been reduced simultaneously.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide a disassembling method of a marine scaffold device, which can ensure the safety of operators below, simultaneously can not damage a lower structure or a paint surface, reduces the workload and improves the efficiency.

In order to achieve the purpose, the invention provides the following technical scheme: a method for disassembling marine scaffold equipment aims at disassembling suspended scaffold equipment installed on a ship (at the reverse top of a deck), wherein the scaffold equipment comprises a scaffold horse, a scaffold and a pedal, and the specific disassembling steps comprise:

firstly, welding a supporting point between two scaffolds, and disassembling a fixing nut between an outer end scaffold and the scaffold;

secondly, a rope penetrates through the supporting points to bind the scaffold, so that auxiliary supporting is realized;

thirdly, the disintegrator moves to the undetached scaffold, and withdraws the disassembled pedal plate to suspend the outer end scaffold in the air;

and fourthly, applying a transverse external force to the suspended scaffold to separate the suspended scaffold from the scaffold, and putting down the suspended scaffold through the rope to finish the dismantling of the scaffold.

Scaffold horse interval welding in the scaffold equipment is on boats and ships, and the scaffold frame is fixed at the scaffold frame at once through bolt cooperation nut, and the scaffold frame below is unsettled setting, and the step board is placed and is formed unsettled operation platform between two scaffolds.

In the first step, the supporting point is a U-shaped frame.

In the first step, the fixing nuts between the scaffold and the scaffold are disassembled, the bolts are kept still, and the scaffold is hung on the scaffold immediately.

In the second step, one end of the rope is tied at the middle part of the scaffold, and the other end of the rope passes through the supporting point and is held in the hand of the disassembling person.

And in the fourth part, a transverse external force is applied to the suspended scaffold through the cross bar.

Compared with the prior art, the disassembling method of the marine scaffold equipment disclosed by the invention has the following beneficial effects: the effect of fixed pulley is realized to welding U type frame next door at scaffold horse, and the cooperation rope realizes slowly transferring of scaffold frame, has guaranteed the safety of below.

Drawings

FIG. 1 is a schematic of the present invention.

Detailed Description

The technical solution of the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention.

As shown in fig. 1, the disassembling method of the scaffold for the ship disclosed by the invention is mainly used for disassembling the suspended scaffold installed at a special part of a ship body, such as a reverse top of a deck, wherein a scaffold is suspended and cannot be disassembled by depending on a peripheral structure.

Concrete scaffold equipment mounting structure includes scaffold horse 1, scaffold frame 2 and step board 3, and scaffold horse interval welding is on boats and ships, and the scaffold frame top is fixed at the scaffold frame at once through bolt cooperation nut, and the scaffold frame below is unsettled setting, and the step board is placed and is formed unsettled operation platform between two scaffold frames.

During disintegration, the operation is carried out from one side to the other side, specifically:

firstly, welding a U-shaped frame 4 between two scaffold horses, dismounting a nut at the upper end of the scaffold positioned at the outermost side, keeping a bolt still, and hanging the scaffold at the scaffold immediately;

one end of the rope is tied at the middle part of the scaffold, and the other end of the rope passes through the U-shaped frame and is held in the hands of the people who disassemble the scaffold;

the disassembling person moves to a position between the two scaffolds without disassembling the nut, the pedal plate on the outer side is retracted, and the scaffold on the outer side is suspended at the moment;

horizontal external force is applied to the suspended scaffold through the cross rods or other objects, so that the scaffold is separated from the scaffold, a disassembler holds the ropes to match the U-shaped frame to slowly put down the scaffold to the bottom, and one-time disassembly is completed.

And the rest scaffolds are disassembled step by step according to the steps until all scaffolds are disassembled. During specific operation, an upper step and a lower step can be built by means of the structural platform or on one side of the scaffold, and when the final scaffold is disassembled, an operator stands on the platform or the steps to operate.

Therefore, the scope of the present invention should not be limited to the disclosure of the embodiments, but includes various alternatives and modifications without departing from the scope of the present invention, which is defined by the claims of the present patent application.
