Description
Technical field
The present invention relates to a kind of ship manhole cover protecting device.
Background technology
In the manufacturing and installation process of boats and ships, the workmen often occurring falls down the manhole of horizontal arrangement from the deck because of carelessness, non-dead great personal safety accident of then hindering takes place, and the danger that in the process of welding, also also can bring in the dilatory friction of manhole cover ring's panel edges owing to electric welding tap line, oxygen, acetylene band, the air compression band of gas etc.
Summary of the invention
The invention provides a kind of ship manhole cover protecting device, it not only can guarantee workmen's safety, and can guarantee the service life of preparation of construction.
The present invention has adopted following technical scheme: a kind of ship manhole cover protecting device, its top is set to guard collar, the bottom is set to connecting panel, it between guard collar and the connecting panel pipe link, guard collar is a horizontal positioned, one side guard collar be opening, the both sides of opening are extended downwards vertically by two pipe links and are drawn close the back and be connected with connecting panel, have connecting bore on connecting panel, guard collar is connected with the manhole cover seat board by connecting panel.
Described guard collar is a square ring.Described guard collar is a galvanized pipe.Described guard collar surface is provided with the noctilucence enamelled coating.Described connecting panel is a steel plate.
The present invention has following beneficial effect: the present invention is connected on the manhole cover seat board, the guard collar that it is provided with can prevent that the workmen from falling down from manhole, cause personal injury, but also electric welding tap line, oxygen and acetylene band, the air compression band of gas etc. of preparation of construction can be hung on the guard collar, potential safety hazard and naked light and explosion hazard that electric welding, oxygen and acetylene bring have been reduced, the service life of the equipment that also can guarantee simultaneously.The present invention is provided with the noctilucence enamelled coating on guard collar, can guarantee that so safety misadventure can not occur evening under the situation of no light.
