When connecting when not having gas in the gasbag 217, the height of limiting plate 221, connection gasbag 217 and fly leaf 207 is the same with the interior top height value of square frame 206, consequently when connecting in the gasbag 217 not gaseous, the horizontal migration of diaphragm 212 can not receive the hindrance, and when connecting gasbag 217 internal existence gas, the top height of limiting plate 221 risees, and then limiting plate 221 can play limiting displacement along square frame 206 to diaphragm 212, and then the stability of effectual assurance device, avoid diaphragm 212 to take place to slide and cause the framed bent subassembly 3 at top to take place to fall the damage.
When the jig frame assembly 3 is used, the support assembly 1 and the lifting assembly 2 are installed according to the first embodiment, then the jig frame assembly 3 is placed on the top of the bearing plate 218, the upright 301 on the peripheral side surface of the jig frame assembly 3 is limited by the limiting plate 221, then the lifting screw 104 rotates to move the movable frame 201 to ascend to the inner bottom of the support plate 103 through the screw sleeve 205, another jig frame assembly 3 is placed at the bottom of the movable frame 201 again, the two jig frame assemblies 3 are spliced through the bolt and the splicing seat 303 in a threaded connection mode, then the horizontal sliding movable plate 207 enables the transverse plate 212 and the bearing plate 218 and the limiting plate 221 on the top to slide along the square frame 206, at the moment, the bottom of the bearing plate 218 is in contact with the top of the transverse plate 212 due to the fact that no gas exists in the connecting air bag 217, the bearing plate 218 and the limiting plate 221 are not in obstruction to the sliding of the transverse plate 212, the movable frame 201 is continuously driven to descend to the bottom of the jig frame assembly 3 on the bottom after the transverse plate 212 slides out, the transverse plate 212, the above actions are repeated, the jig frame assembly 3 is lifted, and multiple groups of the actions are repeatedly inserted, so that the height of the jig frame assembly 3 is continuously increased.
Along with the quantity of bed-jig subassembly 3 constantly increases, the synchronous constantly increase of pressure value that pressure sensor detected, then can obtain the number of bed-jig subassembly 3 amalgamation effectively with the help of the pressure value that pressure sensor detected, thereby reduce the accounting time, accomplish when the installation of last bed-jig subassembly 3, and during movable frame 201 did not rebound to maximum height, the top in bed-jig subassembly 3 top and the wall body of top mutually contact, it is spacing with the help of positioning bolt 216 and the threaded connection of locating hole 113 and then highly carrying on movable frame 201 this moment.
However, since the clearance of the positioning holes 113 is fixed, it may happen that the height of the movable frame 201 is between two adjacent positioning holes 113, when the positioning bolt 216 is screwed into the lower positioning hole 113, the top of the top jig frame assembly 3 cannot contact with the top inside the wall, and when the height of the movable frame 201 is continuously raised, since the top of the top jig frame assembly 3 cannot rise due to the limiting effect of the top inside the wall, at this time, the positioning bolt 216 is screwed into the lower positioning hole 113 to perform first-order height compensation, at this time, the air pump 220 starts to exhaust into the air duct 219, the air circulates to the inside of the connecting air bag 217 along the air duct 219, the connecting air bag 217 increases due to the supplementary volume of the internal air, the connecting air bag 217 drives the top jig frame assembly 218 to move upward, the plurality of sets of jig frame assemblies 3 at the top are driven to move upward when the load plate 218 moves upward, thereby achieving that the top of the top jig frame assembly 3 contacts with the top inside the wall, and satisfying the supporting and limiting effect of the jig frame assembly 3 on the wall by the supporting effect of the elastic buffer assembly 3.
Particularly, the size of the connecting airbag 217 is increased to drive the bearing plate 218 to ascend, the bearing plate 218 drives the limiting plate 221 at the top to ascend, at this time, the limiting plate 221 not only performs limiting protection on the peripheral side surface of the upright column 301 in the jig frame assembly 3, but also the height of the top end of the limiting plate 221 is greater than the height of the inner cavity of the square frame 206, the limiting plate 221 can perform limiting protection on the inner wall of the movable frame 201, so that the transverse plate 212 is effectively prevented from sliding away from the square frame 206, and the stability of the transverse plate 212 is ensured.
When the top of the wall body is an inclined wall surface, after the movable frame 201 rises to a proper height, only one end of the top jig frame assembly 3 is in contact with the top of the wall body, the jig frame assembly 3 cannot effectively support the top of the wall body, the pressure value detected by the pressure sensor on one side of the jig frame assembly 3 in contact with the wall body is increased, the other side of the wall body is not in contact with the wall body because the jig frame assembly 3 and the value of the pressure sensor are not increased, at the moment, the air pump 220 on one side, which is not increased in pressure value detected by the pressure sensor, starts to exhaust air into the air duct 219, the air reaches the inside of the connecting air bag 217 along the air duct 219 and drives the connecting air bag 217 to increase in volume, the bearing plate 218 on the top is driven to continuously rise by the top of the bearing plate 218, therefore, under the supporting action of the connecting air bag 217, the multiple sets of jig frame assemblies 3 are driven to incline by a certain angle, at the moment, the air pump 220 on the other side starts to exhaust air pump 220, the air pump on the other side, the connecting air bag 217 and the pressure value detected by the top jig frame assembly 3 and the pressure sensor on the top of the wall body reaches the preset value.
At this moment, because under the drive of the unequal connection gasbag 217 of both sides volume change, the slope takes place for the multiunit bed-jig subassembly 3 at loading board 218 and top, the slope takes place for the limiting plate 221 along with the slope of loading board 218 in step this moment, consequently, limiting plate 221 still can carry out spacing support to stand 301 week side in the bed-jig subassembly 3, and then guarantee the stability and the support performance of bed-jig subassembly 3, it is synchronous, connection gasbag 217 still can carry out elastic connection to the bed-jig subassembly 3 at top this moment supports, improve the stability and the antidetonation buffering effect that the bed-jig subassembly supported the wall body.
The device is further to carry out the second order compensation to the concatenation height of bed-jig subassembly 3, and the concatenation precision is higher, and is better to the shock attenuation buffering supporting effect of wall body, connects the asymmetric volume change of gasbag 217 with the help of both sides simultaneously and makes the multiunit bed-jig subassembly 3 at top correspond the emergence slope, further increases the support scene of this bed-jig subassembly 3, and adaptability is stronger.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
