(3) summary of the invention
The technical problems to be solved in the utility model is to provide a kind of lane device being elevated grandstand, lifting grandstand as required mobile lifting time once break down, can urgent referral personal security flee from.
For this reason, the utility model takes following technical scheme:
Be elevated a lane device for grandstand, include melt pit, the lifting grandstand be arranged in melt pit, described lifting grandstand includes stage body and guardrail; Also include stationary conduit and servo-actuated passage, described stationary conduit is in being in tilted layout, and low order end and ground maintain an equal level, and high order end is connected with described servo-actuated passage; The corresponding servo-actuated passage side of described stage body has container cavity, described container cavity both sides are provided with pulley track, be provided with pulley yoke in described container cavity, described pulley yoke lateral surface is provided with the first pulley coordinated with described pulley track, the external part of described pulley yoke and the other end of servo-actuated passage hinged.
Described servo-actuated passage and stationary conduit and pulley yoke all adopt " Y " shape articulated structure.
Described servo-actuated passage is slabbed construction, and surface is provided with anti-skidding raised line.
Described stage body side is provided with vertical guiding device.
Described vertical guiding device includes: the concrete post longitudinally arranged, is provided with chute inside described concrete post, and the corresponding runner position of described stage body is provided with the second pulley, and described second pulley is arranged on stage body by lug, and described second pulley coordinates with chute.
Be furnished with some wells in described melt pit, be provided with hydraulic cylinder in described well, the piston rod front end of described hydraulic cylinder is connected with the lower surface of stage body.
Some double-deck scissors struts are provided with between described melt pit surface and stage body lower surface.
Be connected with soft fence between described stage body and servo-actuated passage, described fence and stage body link are positioned at the top of pulley yoke moving area.
The utility model has the following advantages: 1, normality lower platform body is positioned at melt pit, carries out elevating movement when the story of a play or opera needs, to spectators with vivid, air, dazzle and magical impression, meet epoch dynamic aesthetic requirement; 2 once break down, and any height that stage body rests on lifting travel can be fled from by servo-actuated channel arrangement personnel, safe and reliable; 3, structure is unique, anufacturability is good, it is easy to manipulate.
