Abstract
The utility model relates to a boiler externally-raised safety net which comprises a fixed frame, a movable frame, a second lug base and second safety ropes. The fixed frame is respectively fixed to two adjacent building stand columns, the movable frame is installed on the outer side of the fixed frame in a rotary mode through hinge pins, the second lug base is installed at the end of the outer side of the movable frame, and the second safety ropes are fixed to the building stand columns and located above the fixed frame. The movable frame is pulled up through a chain block above the movable frame to gradually get into the slightly-raised state, and at the moment, a safety net body on the movable frame can play the effect of blocking high falling objects. In order to prevent the externally-raised safety net from being damaged by the large high falling objects, the chain block can be tied and hung on the frame of the externally-raised safety net, and the reinforcing effect is achieved. When the externally-raised safety net needs to be retracted during site construction, the movable frame can be rapidly pulled up through the chain block, the externally-raised safety net is recovered in time after construction is completed, and the construction period and the safety requirements are guaranteed. The externally-raised safety net is rapid and easy to assemble, disassemble and operate, and the working efficiency is improved.

Summary of the invention
The utility model is in order to overcome the deficiency of above technology, provide a kind of assembling and disassembling efficiently boiler choose safety net outward.
The utility model overcomes the technical scheme that its technical problem adopts:
This boiler is chosen safety net outward, comprise be individually fixed in two fixed frames on adjacent building column, by bearing pin rotate be installed on fixed frame outside movable frame, be installed on the ear seat II of movable frame outboard end and be fixed on building column and be positioned at the safety rope II of fixed frame top, described bearing pin outboard end is provided with cottor pin, Chain block one end is fixed in ear seat II, its other end is fixed in safety rope II, between described two movable frames, some safety rope I are installed, safety net is fixed in safety rope I.
Above-mentioned fixed frame comprises two fixing clamp arm and two pull bar I, described two fixing clamp arm lay respectively at the rear and front end of building column, described two pull bar I lay respectively at the two ends, left and right of building column, and its two ends are respectively arranged with thread head, the two ends of described two pull bar I is fixed two fixing clamp arm lockings through logical pad I and nut I after two fixing clamp arm respectively.
Above-mentioned movable frame comprises two activity jig arm and pull bar II, described two activity jig arm medial extremitys are rotated and are installed on fixed frame by bearing pin respectively, described pull bar II two ends are respectively arranged with thread head, and the two ends of pull bar II is fixed by pad II and nut II locking through after the outboard end of two activity jig arm respectively.
In order to facilitate mobile fixed frame, the upper end of above-mentioned fixing clamp arm is provided with ear seat I.
In order to prevent from damaging building column, also comprise the rubber sheet gasket being arranged between building column and fixing clamp arm.
The beneficial effects of the utility model are: utilize top Chain block by movable frame pull-up, make movable frame on slightly, choose state gradually.Now, the safety net on movable frame can play the effect that stops high-altitude junk.For preventing that high-altitude junk from causing more greatly the outer safety net of choosing to damage, now chain block always bolt hang over outer choosing on screen frame frame, play reinforcement effect.When site operation need to be when choosing safety net outward and pack up, can be by chain block fast by movable frame pull-up, after construction, will choose in time safety net outward and recover, ensure construction period and safety requirements.Installation, dismounting and simple and quick, improved operating efficiency.
