In some of these embodiments, as shown in FIG. 11 , the driven unit 200 further includes a fourth limiting element 234 and an electromagnet 235 .

The fourth limiting element 234 is arranged on the lower side of the proximal end of the mounting element 205, and is located inside the limiting groove opened at the lower end of the second mounting groove 103, and is used to limit the mounting element 205 and prevent the mounting element 205 from being too outward. to move.

The electromagnet 235 is arranged in the limiting groove, and is arranged corresponding to the fourth limiting element 234, and is electrically connected with the control unit 600, and is used to limit the fourth limiting element 234 under the control of the control unit 600. position, and then limit the installation component 205.

Specifically, the driving mechanism drives the active unit 700 to rotate in reverse, and the active unit 700 drives the two driving elements 201 to rotate in reverse. At this time, the control unit 600 controls the opening of the electromagnet 235 to limit the fourth position-limiting element 234, so as to The fourth limiting element 234 is prohibited from moving, so the driving element 201 drives the transmission element 208 to rotate in the opposite direction, and moves the first limiting element 206 to reciprocate until the turning supporting element 216 is turned to the horizontal, and the telescopic supporting element 218 The rack in the telescopic hole 226 is retracted, and then the control unit 600 controls the closing of the electromagnet 235 to release the fourth limiting element 234.

The positioning element 206 , since the electromagnet 235 does not limit the fourth limiting element 234 , the transmission element 208 can drive the installation element 205 into the second installation groove 103 at this moment.

The working principle of the flip plate adjustment support structure for a four-way car paving track of the present invention is: when the four-way car management system is down, the control unit 600 controls to open the lifting unit 500 at this time, and the lifting unit 500 drives the track The unit 400 moves downward, and then the driving mechanism drives the active unit 700 to rotate, so that the active unit 700 drives the two drive elements 201 to rotate simultaneously through the transmission gear 703, and the drive element 201 rotates to drive the installation element 205 to move to the outside of the second installation groove 103 Squeeze the turning unit 300 to turn outward, and then when the driving element 201 is engaged with the first limiting element 206, the driving element 201 drives the transmission element 208 to rotate, and the first limiting element 206 is moved to reciprocate, Thus, the mounting element 205 stops moving to the outside, and the transmission element 208 drives the rotating element 209 to rotate, and the rotating element 209 drives the first driven element 212 and the second driven element 217 to rotate. In the first driven element 212 The second driven gear 230 rotates under the drive of the first tooth 211, and then drives the transmission column 220 and the overturn support element 216 to rotate and overturn, so that the overturn support element 216 drives the overturn unit 300 to overturn to cover the track laying groove 101 At the same time, the driven column 229 in the second driven element 217 drives the third driven gear 231 to rotate, the third driven gear 231 drives the fourth driven gear to rotate, and the fourth driven gear drives the second The rack 232 is far away from the telescopic hole 226, so that the second support plate 233 abuts against the track unit 400. When the overturning support element 216 is overturned to the vertical direction and abuts against the overturning unit 300, the telescopic support element 218 and the track unit 400 abut against each other, so as to realize the overturn support for the overturn unit 300 .

In addition, when the turning plate needs to be retracted into the turning groove, the control unit 600 controls to turn on the electromagnet 235 at this time, so that the electromagnet 235 attracts the fourth limiting element 234. At this time, the driving mechanism drives the active unit 700 to perform reverse rotation. The active unit 700 drives the two driving elements 201 to rotate in the opposite direction. At this time, since the fourth limiting element 234 cannot move, the driving element 201 drives the transmission element 208 to rotate in the opposite direction, turning the overturning support element 216 to the level, and the telescopic support element The rack in 218 is retracted into the telescopic hole 226, and then the control unit 600 controls the closing of the electromagnet 235 to release the fourth limiting element 234. At this time, the driving element 201 rotates to drive the mounting element 205 into the second mounting groove 103.
