Description
Technical field
The present invention relates to hanging object blind patch opening device.
Background technology
Hanging object hole safety device（Also commonly referred to as：Hanging object blind patch）It is that one kind applies the equipment in tier building to rise
Lifting hole(eyelet) hole or the safety protection equipment for overhauling hole, for example：Power station, thermal power plant, steel plant and some enterprises, such rises
Lifting hole(eyelet), manhole are generally using common steel deck-plate or movable steel deck-plate capping hole.It is artificial to open difficult, automaticity bottom,
Using difficulty, security is poor.
The content of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of rational in infrastructure, processing and manufacturing simplicity；During unlatching take 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 impulsive force that cover plate is opened is also smaller；
The balance jack up hanging object blind patch that cover plate is applied widely, security performance is high.
To realize the object of the invention, there is provided following technical scheme：One kind balance jack up hanging object blind patch, including cover plate
Housing, the door-plate being hinged with cover plate housing, it is characterised in that vertical rack, vertical rack lower end hinge are installed below cover plate housing
Connect nearly cover plate housing side below inclined support bar lower end, door-plate and be hinged swing arm left end, swing arm right-hand member is provided with balancing weight, inclined support bar
Being hinged between upper end and swing arm two ends is point articulated, 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, locked after locking nut regulation is installed.
Preferably, being hinged with secondary door-plate on the outside of door-plate.
Preferably, nearly cover plate housing side on the door-plate of swing arm left end hinged place with being provided with rotating shaft, swing arm left end is arranged
In in rotating shaft and be machined with install with door-plate on driving gear meshed gears structure, driving gear connection power source.
Beneficial effect of the present invention：Rationally, processing and manufacturing is easy for covering plate structure of the present invention；Less activity is taken during unlatching empty
Between；Lower swing arm swing angle is small, and the furnace hole lower part space of occupancy is also small, and the impulsive force that cover plate is opened is also smaller；Cover plate is applicable model
Enclose wide, security performance high.
