Description
Technical field
The present invention relates to hanging object blind patch opening devices.
Background technique
Hanging object hole safety device (also commonly referred to as: hanging object blind patch) is a kind of equipment to be applied in tier building to rise
Lifting hole(eyelet) hole or the safety protection equipment for overhauling hole, such as: power station, thermal power plant, steel plant and some enterprises, such rises
Lifting hole(eyelet), manhole generally use common steel deck-plate or movable steel deck-plate cap hole hole.It is artificial to open difficult, the degree of automation bottom,
Using difficulty, safety is poor.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of structurally reasonable, processing and manufacturing simplicity；When unlatching occupy compared with
Few activity space；Lower swing arm swing angle is small, and the furnace hole lower part space of occupancy is also small, and the impact force that cover board is opened is also smaller；
The balance jack up hanging object blind patch that cover board is applied widely, security performance is high.
Purpose to realize the present invention provides following technical scheme: a kind of balance jack up hanging object blind patch, including cover board
Outline border and the hinged door-plate of cover board outline border, it is characterised in that vertical rack, vertical rack lower end hinge are installed below cover board outline border
Inclined support bar lower end, the nearly hinged swing arm left end in cover board outline border side below door-plate are connect, swing arm right end is equipped with clump weight, inclined support bar
It is hinged point articulated between upper end and swing arm both ends, so that vertical rack, door-plate, inclined support bar and swing arm is hinged, door-plate,
Inclined support bar, swing arm relative rotary displacement.
Preferably, inclined support bar upper end is screw telescopic structure, it is equipped with after locking nut is adjusted and locks.
Preferably, being hinged with secondary door-plate on the outside of door-plate.
Preferably, being provided with shaft on the door-plate of nearly cover board outline border side and swing arm left end hinged place, swing arm left end is arranged
In in shaft and be machined with installation with door-plate on driving gear meshed gears structure, driving gear connect power source.
The invention has the advantages that: covering plate structure of the present invention is reasonable, processing and manufacturing is easy；It is empty that less activity is occupied when unlatching
Between；Lower swing arm swing angle is small, and the furnace hole lower part space of occupancy is also small, and the impact force that cover board is opened is also smaller；Cover board is applicable in model
Enclose wide, security performance height.
