Description

Marine manhole cover guard ring frock

Technical Field

The utility model relates to a ship construction technical field especially relates to a marine manhole cover protective shroud frock.

Background

After the ship is started to build a section, such as an inner bottom section, a top side cabin section, a deck section and the like, a plurality of manhole openings (the opening specification is generally 800 × 600 and 600 × 400) for entering the cabin to work are arranged on an inner bottom plate, a platform and a deck of the ship. The practice in the past is that round spot welding steel pipe and round blocking cement come the safety of protection people around the manhole and prevent that rainwater from flowing into the cabin, not only will cut off the steel pipe of whole root, still need the scaffold to connect the fastener and connect, the tip of steel pipe does not have the protective measure personnel and touch the injury very easily, and the instrument that personnel got into the cabin during operation in addition is inconvenient to be placed, the assurance personnel's that can not be fine safety, and work efficiency is also lower.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a marine manhole cover guard ring frock, including railing and bounding wall that the internal diameter is greater than the manhole, the shape of railing is the regular annular that has the opening, the shape of bounding wall is the same with the shape of railing, the hypomere of railing lateral wall hugs closely the first half setting of bounding wall inside wall, the top of bounding wall and railing lateral wall pass through welded fastening, railing bottom and bounding wall inside wall pass through welded fastening; the railing and the coaming are arranged on the outer ring of the manhole on the deck or the inner bottom plate, and cement is enclosed between the periphery of the coaming and the deck or the inner bottom plate.

The utility model discloses the technical scheme who further injects is:

the marine manhole cover retainer tool further comprises a chain, one end of the chain is fixed at an opening at one side of the handrail, and the other end of the chain can be detachably fixed at an opening at the other side of the handrail.

The marine manhole cover guard ring tool further comprises a plurality of hooks, and the hooks are fixed at the positions, close to the coaming, of the handrails.

The utility model has the advantages that: the workload efficiency of workers is improved, the safety of the upper manhole and the lower manhole of the workers is guaranteed, and meanwhile the project cost is reduced.

Detailed Description

The marine manhole cover retainer tool provided by the embodiment has the structure as shown in the figure, the size is designed according to the size of a manhole, and the marine manhole cover retainer tool comprises a handrail 1 and a coaming 2, wherein the inner diameters of the handrail 1 and the coaming 2 are both larger than the inner diameter of the manhole, the handrail 1 is in a regular annular shape with an opening, the coaming 2 is in the same shape as the handrail 1, the lower section of the outer side wall of the handrail 1 is closely attached to the upper half part of the inner side wall of the coaming 2, the top of the coaming 2 is fixed with the outer side wall; the railing 1 and the coaming 2 are arranged on the outer ring of the manhole on the deck or the inner bottom plate, and cement is enclosed between the periphery of the coaming 2 and the deck or the inner bottom plate. Still include

chain

3, 3 one end of chain is fixed in one side opening part of railing 1, and the other end can be dismantled and be fixed in the opposite side opening part of railing 1. The guardrail also comprises a plurality of hooks 4, wherein the hooks 4 are fixed at the parts of the railings 1 close to the coamings 2.

The cost of the improved manhole cover protection ring tool is a little more in the view of the previous labor investment, but the safety of the improved manhole cover protection ring tool can be well guaranteed in the view of safety and long term, and the improved manhole cover protection ring tool is free of maintenance. The coaming 2 can prevent sundries from falling into the manhole and injuring constructors; the chain 3 can prevent the constructor from falling into the manhole carelessly after the constructor is hung on the manhole; the hook 4 can be used for hanging oxygen, acetylene and CO2 belts for construction, and plays a role in protecting the belts; the device has no protruding sharp corner, so that the personnel is well protected from being injured; after a ship is manufactured, the ship can be repeatedly used on a subsequent ship, and the safety is really guaranteed, the cost is reduced, the efficiency is improved, and the ship can be repeatedly used.

In addition to the above embodiments, the present invention may have other embodiments; all the technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope claimed by the present invention.
