The driving gear 54 of driving, rack gear carrier bar assembly include that the multiple successively hinged carrier bar monomer 511 of head and the tail, carrier bar monomers are equipped with
The rack gear 55 that can be engaged with driving gear, driving box are equipped with the vertical guide mouth for being oriented to carrier bar monomer, are equipped in hutch
For accommodating the guiding accommodating chamber of each carrier bar monomer, rack gear carrier bar assembly one end is in guiding accommodating chamber, rack gear carrier bar assembly
The other end is hinged with attachment base.
The ride is equipped with multiple fixing legs 11, and the fixing leg includes the screw body 111 arranged vertically, setting
In screw body lower end and for contacting the supporter 112 on ground and the turn handwheel 113 of screw body upper end, the screw rod being arranged in
Body passes through ride and is threadedly engaged with ride.After ride moves in place, it can be driven with each fixed branch angle (turn handwheel) of turn
Screw body rotation moves down, and supporter contact ground, movable pulley is made to leave ground, so that ride and integrally-built firm can be realized
Positioning.
The movable pulley is universal wheel, and movable pulley number is 6 to 10.For common movable pulley, universal wheel is more
Conducive to movement, facilitate integral shift of the invention.
The ride is equipped with multiple air-cushion devices, and air-cushion device includes air bag cushion 61 and the setting that ride bottom is arranged in
Air pump 62 on ride and for supplying to air bag cushion, in an air-cushion device: air pump passes through loading line and air bag cushion
Connection, air bag cushion bottom are equipped with multiple stomatas.
Place of the present invention before the lights when, if desired adjust position of the invention, each air pump can directly be allowed to fill to each air cushion
Gas, air cushion are heaved, and gas sprays downwards from each stomata, lift entire ride, and the structure that makes to contact to earth all leaves stage surface (gas
The lower one layer of air film formed of pad is lifted ride), so as to directly easily move the present invention to position (the stage surface needed
Completely cut off completely by air film between entire ride, movement is got up " no friction ", and resistance is very small, shifts rapid and convenient), it is moved to
Behind position, each air pump stops gas supply, and air film disappears, and ride is fallen again.In addition, air-cushion device and movable pulley can with cooperating,
When ride excessively uneven (center of gravity is excessively biased to certain side), a part of movable pulley can provide support, and stage is avoided to deviate
Degree.
The air-cushion device number is 4 to 8, and air pump is in the top of air cushion.
It is set on the dynamic ladder there are two the protection fence 7 being arranged symmetrically, any step monomer is in two protection fences
Between；
Protecting fence includes upper railing 71, middle railing 72 and multiple connection railings 73, in a protection fence: upper railing
It is parallel to middle railing, upper railing is parallel to steelframe bar, and it connects railing upper end and upper railing is hinged, connection railing middle part and intermediate hurdles
Bar is hinged, connects railing lower end and upper steelframe bar is hinged；It is equipped with tension member 74 by dynamic ladder, tension member is parallel to any connection column
Bar, tension member upper end connect railing connection with one of, and ride is equipped with chain 75, and chain one end is connect with ride, chain
The other end is connect with tension member lower end.
After (dynamic ladder) of the invention falls gathering, protection fence is also at rounding state, upper railing, middle railing and connection column
Bar is in horizontality.The present invention moves during ladder rise expansion: at the beginning, upper railing, middle railing and connection railing are homogeneous
It is static to upper steelframe bar；After upper steelframe bar reach a certain height, tension member is by chain pull-up, tension member rotation, to drive
It protects fence to rise, forms protection.
The dynamic ladder is equipped with filling-in mechanism, and filling-in mechanism includes mounting base 81, filling-in frame 82, is arranged in upper steelframe bar
On guide rail and electric pushrod 83 for pushing filling-in frame to slide along guide rail, filling-in frame be equipped with the sliding block being adapted to guide rail,
Electric pushrod is hinged with mounting base, and mounting base is arranged on upper steelframe bar.Electric pushrod can release filling-in frame, make filling-in frame with
The surface (such as surface of upper layer stage) of required docking connects flat.If filling-in frame has height difference or filling-in with the required surface docked
Gap between frame leading edge and the required surface docked is too big, then can be solved by going up and down dynamic ladder, moving carriage-table.
At the beginning, the present invention, which is in, falls rounding state.When needing using the present invention, using universal wheel and air-cushion device
Push the present invention to the designated position on stage.Then ride is positioned using fixing leg.Driving gear drives rack gear carrier bar
Assembly stretches out driving box, to drive upper steelframe bar, lower steelframe bar to rotate rise along respective hinge joint together, in this process
In, the relatively upper steelframe bar of step monomer rises, and forms continuous step.After upper steelframe bar reach a certain height, tension member
Start by chain pull-up, tension member rotation forms protection so that protection fence be driven to rise.Subsequent electric pushrod can be by filling-in
Frame is released, and filling-in frame connects flat with the required surface docked.Performer is i.e. using the present invention at this time, in the performance region of different height
Between shifted.
