Abstract
The utility model relates to modification of openable overturning door plate for a safety guardrail device, which is characterized in that a movable inclined support connected with a hoisting hole frame or wall is arranged below a main door plate, and an auxiliary door plate is reinforced by an extending or rotating movable door block. The openable overturning door plate overcomes the shortages in the prior art, the main door plate support is reinforced more singly, integral bearing capacity of the large-span hoisting hole door plate is further increased, no addition thickness of the door plate is needed, the effective space of the hosting hole is maximized, further, door plate materials are saved, and opening/closing power is reduced.
Description
Technical field
Utility model relates to a kind of multistory building interlayer hanging device--floor hole for hoist safety barrier device, the improvement of especially the safety barrier device being dug movable doorboard.
Background technology
Along with hanging continuing to increase of thing hole area, for example occur 11 * 12 meters and hang the thing hole greatly, it is increasing that door-plate is dug in the activity that the thing hole is hung in feasible covering, and hang thing hole door-plate is the load-bearing door-plate, and big width and length requirement door-plate thickening or employing strengthen structure, but thickening or enhancing structure all can cause material and weight to increase, and On/Off power increases, increase door-plate thickness simultaneously, also can cause increasing to occupy hanging object space, this all is undesirable.
Chinese patent CN201224937 hangs thing hole door-plate structure of assistant support, proposes to adopt the bearing diagonal that comprises chute, bearing and support bar to strengthen mode, overcomes thickening or adopts the deficiency that strengthens structure.This adopts bearing diagonal to strengthen mode, it only is the main door-plate support reinforcing of hanging thing hole frame to being hinged on, and this piece door-plate is limited in width to be not more than in 1.5 meters because of hanging object space, people's sight line requirement usually, so because narrow relatively actual this piece reinforcement meaning of width is limited.And hang the thing hole for large span, and people often adopt and increase secondary door-plate width way, and broadening partly is positioned at the floor back side, and the reinforcement of the secondary door-plate of the therefore big width main door-plate that compares is more important.
The utility model content
The utility model purpose is to overcome above-mentioned the deficiencies in the prior art, provides a kind of and can guarantee big width not increasing under door panel structure intensity and the thickness, and length hides door-plate has the thing hole activity of hanging of sufficient intensity to dig door-plate.
The utility model purpose realizes that main the improvement is at the main door-plate back side movable bearing diagonal to be set, and main door-plate is strengthened, and secondary door-plate is by stretching out or produce a shoe last or hat block and strengthened, thereby overcomes the deficiencies in the prior art, realizes the utility model purpose.Specifically, utility model is hung the activity of thing hole and is dug door-plate, comprises main door-plate and one or two secondary door-plate that can overturn, and it is characterized in that main door-plate below has connection to hang the movable bearing diagonal of thing mouth frame or wall, and secondary door-plate is by stretching out or producing the dodge gate shoe last or hat block and strengthen.
Utility model is said:
Movable bearing diagonal, its form of structure can have two kinds, and the one end is fixed, the other end is slidingly connected with the door-plate back side respectively or is slidingly connected with frame or wall support end, utility model better adopts the latter, and promptly bearing diagonal one end is fixed on the main door-plate back side, and the other end and frame or wall upper rail are slidingly connected.
The reinforced door shoe last or hat block both can be strengthened closing secondary door-plate by flexible or folding upset, can strengthen closing secondary door-plate by producing/going back to again.They all can make its motion by movable machinery (for example oil cylinder or screw mandrel straight line push away/draw, and crank, cam rotation eject etc.), also can be by manually making its motion, its be provided with can be door-plate just towards, also can be at the door-plate back side to.
Same prior art, utility model are hung the activity of thing hole and are dug door-plate, can also comprise the flexible fence at two ends.
Utility model is hung the activity of thing hole and is dug door-plate, with respect to prior art, owing to adopt main door-plate and secondary door-plate are strengthened simultaneously, wherein adopt similar door shoe last or hat block to strengthen to secondary door-plate, be equivalent to the beam of choosing in the building structure, thereby the deficiencies in the prior art have been overcome, more single to main door-plate support reinforcement, improved the integrated carrying ability that large span is hung thing hole door-plate especially, and do not need to increase separately door-plate thickness, not only make and hang the usefull space maximization of thing hole, and saved panel material, and reduced and opened/close power.
Below in conjunction with three specific embodiments; utility model essence is further understood in exemplary illustration and help; but the embodiment detail only is for utility model is described; do not represent utility model design whole technical schemes down; therefore should not be construed as the total technical scheme of utility model is limited; some are In the view of the technician; the unsubstantiality that does not depart from the utility model design increases and/or change; for example change or replace, all truely use novel protected scope so that technical characterictic with same or similar technique effect is simple.

Fig. 2 is the second example structure schematic diagram.
Fig. 3 is the 3rd example structure schematic diagram.
The specific embodiment
Embodiment 1: referring to Fig. 1, utility model is hung the thing hole and is dug movable doorboard, hang thing hole periphery in large span and be provided with fixed frame 1, dig main door-plate 3.1 by hinge 2 activities of being hinged with on the framework 1, and and the hinged secondary door-plate 3.2 of main door-plate, at the alternate guide rail of stretching under two 4.1 that is provided with of the axial framework of rotating shaft, the main door-plate back side is hinged with inclined support bar 5, there is stressed governor motion 7 at hinged some place, be used to adjust the door-plate level, the other end of support bar can slide up and down according to guide rail 4.1, closes the back at main door-plate and plays the reinforcement supporting role.There is the door shoe last or hat block 10.1 of alternate three row's axial stretchings at the main door-plate back side, the major-minor door-plate has three row's fixed gate shoe last or hat blocks to impale 6.1 and 6.2 respectively to the shoe last or hat block position of answering the door, the door shoe last or hat block pushes away/pulls shoe last or hat block by the pin rod 11 that stretches out the thick groove of door-plate, after secondary door-plate cuts out, by releasing secondary door-plate is strengthened.Two ends also have flexible fence (not providing among the figure).
Embodiment 2: referring to Fig. 2, as embodiment 1, wherein main door-plate has the bearing diagonal mode opposite, and bearing diagonal 9 is fixed on the doorframe bar 4.2, and the other end is along main door-plate back side chute 12 sliding supports; Each shoe last or hat block has electronic screw mandrel 8 to push away/stretch to contract.
Embodiment 3: referring to Fig. 3, as described above, a door shoe last or hat block 10.2 of wherein strengthening the secondary door-plate of support is positioned at above the door-plate, and is built in the door-plate thickness by dodge gate.
