When dynamic section 231 deflects with respect to sliding groove 2121, it is circumferential that at least one sliding shoe 2322 can correspond to connecting shaft 2321 relatively
Rotation, to be bonded with corresponding upper cell wall 2123 or lower cell wall 2125, realizes to be oriented to and slides, be not construed as limiting herein.
It should be understood that ground, in some other embodiment, the quantity of the guidance set 232 set on each load-carrying part 230
Can as needed depending on.In one of the embodiments, in both 231 first end 2310 of glissile segment and second end 2312
The quantity of guidance set 232 at least one is two groups, such as when setting two groups of guidance sets 232 in first end 2310,
Two groups of guidance sets 232 are set with (i.e. the width of sliding slot 2121) of vertical first direction；Normal condition (i.e. load-carrying part
During 230 non-load), one is bonded with upper cell wall 2123 in two groups of guidance sets 232, and another one is bonded with lower cell wall 2125；When
Load-carrying part 230 is when load deflects, sliding shoe in the guidance set 232 being bonded in first end 2310 with upper cell wall 2123
2322 opposite glissile segments 231 rotate in a circumferential direction, and remain that face is contacted with face with lower cell wall 2125.
Crossbeam gear 50 is arranged on the load-carrying part 230 of guiding mechanism 23, and is connected with being oriented to actuator 40, to be oriented to drive
Stretch along sliding slot 2121 with guiding mechanism 23 under the driving of moving part 40, be positioned over keeping out on flip-arm 21 in a first direction
Concrete PC plate, prevents it from gliding and dropping when being overturn with flip-arm 21.
Referring again to Fig. 1, in this embodiment, roll-over table 100 includes two pedestals 10, is respectively arranged at two
Flip-arm 21 on pedestal 10, the upset actuator 30, two for being respectively used to provide driving forces for two flip-arms 21 are oriented to and drive
Moving part 40, be oriented to guiding mechanism 23 and a crossbeam gear 50 that actuator 40 is connected with two respectively.Crossbeam gear 50 is along vertical
First direction is connected between two guiding mechanisms 23, for transversely keeping out in concrete PC plate, prevent it due to upset and
Roll.
During the work time, steel trolley is carried concrete PC plate and run to the correct position above flip-arm 21, lead
Into actuator 40, guide extension end 43 is stretched out, and load-carrying part 230 is existing along sliding slot 2121 to close to steel in the guiding of guidance set 232
Trolley direction is slided, the side for concrete PC plate guiding mechanism 23 on steel platform that crossbeam gear 50 is fended off；Wherein due to sliding
Block 2322 can be adaptive in the case of 230 load of load-carrying part the axis around connecting shaft 2321 relative to load-carrying part 230 rotate to
It is bonded with corresponding upper cell wall 2123 and lower cell wall 2125 in a manner of face is contacted with face, avoids load-carrying part 230 from driving crossbeam
There is abrasion that is stuck and reducing sliding shoe 2322 in gear 50 during sliding.
Piston rod stretches out in two upset actuators 30, by flip-arm 21 around its hinge joint with mounting lug 13 to by
The direction of nearly support arm 2102 rotates, and flip-arm 21 is begun turning from horizontal level around mounting lug 13, arm 21 to be flipped is overturn
During to the horizontal predetermined angular, upset actuator 30 stops stretching out, and driving starts to demould, and lifts by crane concrete PC plate.
It is oriented to guide extension end 43 in actuator 40 to retract, crossbeam gear 50 slides into initial position, waits next time flat
Move；Overturn piston rod in actuator 30 to retract, flip-arm 21 carries steel trolley and is back to horizontal level, waits next block concrete
The carrying of PC plate.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope that this specification is recorded all is considered to be.
Embodiment described above only expresses the several embodiments of the utility model, its description is more specific and detailed,
But therefore it can not be interpreted as the limitation to utility model patent scope.It should be pointed out that the common skill for this area
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
