The front end of side protecting mechanism and back timber 1 is hinged, and side protecting mechanism is provided with the wall supporting jack, is used to drive side protecting mechanism and rotates, to realize the wall supporting function of side protecting mechanism.
Concrete side protecting mechanism can comprise one-level wall supporting 6, secondary wall supporting 9, three-stage side protecting 13;
Be provided with one-level wall supporting jack 7 between back timber 1 and the one-level wall supporting 6, be same as the motion that drives one-level wall supporting 6;
Be provided with secondary wall supporting jack 8 between one-level wall supporting 6 and the secondary wall supporting 9, be used to drive the motion of secondary wall supporting 9;
Be provided with three-stage side protecting jack 10 between secondary wall supporting 9 and the three-stage side protecting 13, be used to drive the motion of three-stage side protecting 13.
Back timber 1, one-level wall supporting 6, secondary wall supporting 9, three-stage side protecting 13 are hinged successively, form the combination side protecting mechanism.
Concrete connected mode can be:
As shown in Figure 2, the front end of the rear end of one-level wall supporting 6 and back timber 1 is hinged, and the front portion of back timber 1 slidely connects the one-level wall supporting and drags seat 5, and the one-level wall supporting drags and is provided with flexible wall supporting jack 2 between seat 5 and the back timber 1, is used to drive the one-level wall supporting and drags seat 5 to slide along back timber 1; One end and the one-level wall supporting 6 of one-level wall supporting jack 7 are hinged; The other end and one-level wall supporting drag seat 5 hinged.Like this, drag seat 5 when back timber 1 slides when flexible wall supporting jack 2 drives the one-level wall supportings, the one-level wall supporting drags seat 5 just to promote the back end motion of one-level wall supporting jack 7, controls the motion of one-level wall supporting 6 jointly with the motive force of one-level wall supporting jack 7 self.
The front end of one-level wall supporting 6 and secondary wall supporting 9 are hinged, and the pin joint between the two is positioned at the postmedian of secondary wall supporting 9, and are positioned at before the aft terminal of secondary wall supporting 9.
As shown in Figure 3, be provided with quadric chain between secondary wall supporting 9 and the three-stage side protecting 13, an end and the secondary wall supporting 9 of three-stage side protecting jack 10 are hinged; The other end and quadric chain are hinged, can control the action of three-stage side protecting 13 by quadric chain.
As shown in Figure 4, quadric chain comprises long connecting rod 11, short connecting rod 12, and long connecting rod 11 is hinged with an end of short connecting rod 12; The other end of long connecting rod 11 and secondary wall supporting 9 are hinged; The other end of short connecting rod 12 and three-stage side protecting 13 are hinged; The rear end of the front end of secondary wall supporting 9 and three-stage side protecting 13 is hinged.Like this, just formed quadric chain between long connecting rod 11, short connecting rod 12, secondary wall supporting 9, the three-stage side protecting 13 4.
