The specific embodiment
See also Fig. 1 and Fig. 2, a kind of moveable terrace for spectator support, the employing welding manner is connected between the lower guideway 4 that has braced structures, is fixedly connected on the pedal support of braced structures top and is fixedly connected on the braced structures below, braced structures and pedal support and lower tumbler;
Described braced structures by two diagonal braces 1, between two diagonal braces 1 diagonal member 2 and be fixed in the running board stay 8 on diagonal brace top, diagonal member is two, the two is arranged in a crossed manner between two diagonal braces, is connected with bolt between diagonal member and diagonal brace, increases its flexibility;
Described pedal support is made up of riser 6, front-axle beam 7 and upper rail 3, pedal support is a rectangle, described riser 6 parallels with front-axle beam 7, upper rail 3 is three, three 3 on guide rails parallel setting, described upper rail 3 one ends are connected with front-axle beam 7, and the other end is connected with riser 6, in upper rail 3 guide grooves rubber tire (not shown) are installed;
The row's of being equipped with lock 5 on the described lower guideway 4, row's lock 5 is arrestment mechanisms of motion, when the stretching, extension of moveable terrace for spectator support is used, can stop the platform accident to be closed; In described lower guideway 4 guide grooves rubber tire 11 is housed, buphthalmos wheel 10 is housed on lower guideway 4 lateral walls, in whole platform support motion process, if wiping, lower guideway 4 lateral walls run into the obstruction in the place ahead, buphthalmos wheel 10 can play guide effect, adjust the direction of motion of whole platform support, prevent the generation of lower guideway 4 lateral walls and the mutual stuck phenomenon of obstruction, make platform support return to original tracks.
See also Fig. 3 and Fig. 4, structural representation for another kind of moveable terrace for spectator support, support height is higher, fixing drag link 9 between two diagonal braces of braced structures, drag link 9 be respectively equipped with cross one another two diagonal members 2 up and down, drag link 9 can increase the stability of moveable terrace for spectator support.
See also Fig. 5, shown the position relation of diagonal brace, lower guideway 4, running board stay and row's lock 5, lower guideway 4 and pedal support are welded on diagonal brace 1 two ends, and it is that central hub is taken exercises that row's lock 5 is connected on the guide rail 4 and with the bolt with bolt.
The motion mode of this moveable terrace for spectator support is: every group platform carries out linearity and moves, and the rubber tire 11 in lower guideway 4 guide grooves contacts with the bottom surface, the direction that upper rail 3 and the common controlling platform of guide groove move.When grandstand launched, whole platform moved along the guide rail direction is linear, motion put in place (reaching the lower guideway end) thus the time row lock 5 under action of gravity, fall to locking every group platform naturally, cause unsafe factor to guarantee unlikely in use unexpected sliding of every group platform.When grandstand is closed, arrange and lift under the effect that is locked in lower guideway 4 to guarantee well return of every group platform, the return process is that support is in the process that retreats, the plate of guide rail 4 back is locked jack-up to back one row's row, like this, the lock of one Pai Ding back of front, whole grandstand be by rows withdrawal position just.In whole platform support motion process, if run into obstruction, buphthalmos wheel 10 can play guide effect, adjusts the direction of motion, prevents that stuck phenomenon from taking place, and makes it return to original tracks.
