In order to more accurately control the amount of expansion and contraction of the levitation support mechanism 4, as shown in fig. 4 to 5, the hydraulic control system 52 includes a proportional pressure reducing valve 521; a proportional pressure reducing valve 521 is provided between the hydraulic pump source 51 and the levitation support mechanism 4 through a hydraulic line. By arranging the proportional pressure reducing valve 521, the proportional pressure reducing valve 521 supplies oil to the bearing cavity 411 of the suspension support mechanism 4, the bearing weight on each suspension support mechanism 4 after transfer is accurately measured, and then the pressure value of the proportional pressure reducing valve 521 is determined, namely the value of the bearing weight of the suspension support mechanism 4, so that the hydraulic control system 52 can control the expansion and contraction amount of the piston rod 43 of the suspension support mechanism 4 more accurately, and a necessary foundation is further provided for the balance stability and the synchronism of the translation transition stage of the building 1.

The proportional servo valve 526 is provided between the hydraulic pump source 51 and the suspension support mechanism 4 through a hydraulic line; and the proportional servo valve, the displacement sensor and the error value of the hydraulic control instruction form displacement closed-loop control, and the output pressure of the displacement closed-loop control controls the lifting, suspending or falling of the suspension support mechanism. If only powerful closed-loop control is performed, the hovering position of the building 1 is unstable, and therefore, in order to improve the stability of the hovering position of the building 1, the hydraulic control system 52 provided in the present embodiment is configured to install four displacement sensors 525 (the number of large buildings can be increased as appropriate) on four diagonal outer sides of the building 1, specifically, the horizontal displacement sensors 525, so as to monitor the horizontal displacement change of the building 1 during the jacking and translation processes in real time, and form the position closed-loop control together with the hydraulic control command of the hydraulic control system 52.

In addition, the hydraulic pump source 51 can also add a pressure to the proportional pressure reducing valve 521 through the proportional servo valve 526 which is controlled by the displacement closed loop, so that the pressure in the suspension support mechanism 4 can be more accurately controlled, the state of the suspension support mechanism is controlled to be lifting, hovering or falling, and the control precision of the suspension support mechanism 4 is further improved.
In order to improve the operation stability of the hydraulic control system 52, as shown in fig. 4 to 5, the hydraulic control system 52 is a PLC hydraulic synchronous control system. The PLC hydraulic synchronous control system adopts a force and displacement double closed-loop control principle, meets the double closed-loop control of the force and the displacement of the suspension support sliding device, and has the advantages of high working reliability, strong applicability, easy transformation, convenient maintenance and the like, so that the PLC hydraulic synchronous control system is arranged to further ensure the synchronism and the safety of the translation construction process of the building 1.
The control principle and the process of the PLC hydraulic synchronous control system are as follows: before the building 1 is suspended and translated, the building 1 is weighed, and the outlet oil pressure P of the proportional pressure reducing valve 521 is adjustedoutRespectively and slowly adjusting the jacking force of each suspension support mechanism 4 to lift the building 1, when the building 1 is just separated from the original foundation, the jacking force of the suspension support mechanisms 4 is the weight of the building 1 at the point, the load of each jacking point of the building 1 is obtained, and the pressure parameters of the proportional pressure reducing valves 521 are fixed
Position (output pressure P of proportional pressure reducing valve 521)outEqual to the regulated pressure P of the proportional servo valve 526CSet pressure P with proportional pressure reducing valve 521DAnd (3) the sum: pout＝PC+PD，
Average control pressure), a closed-loop synchronous lifting stage can be switched, and when the control system adjusts the pressure of each suspension support mechanism 4 to be higher than the weighing pressure, the building 1 can be lifted; when the pressure of each suspension support mechanism 4 is adjusted to be lower than the weighing pressure, the building 1 falls back; and by position closed-loop control, the building 1 can be accurately hovered at an arbitrary position. The pressure sensor 523, the displacement sensor 525, the proportional servo valve 526 and the proportional pressure reducing valve 521 form a closed loop together to adjust the output pressure supplied to the suspension support mechanisms 4 in real time, so that each suspension support mechanism 4 is in a dual controlled state. Because n buildings are arranged below the building 1The suspension support 4 and, therefore, here the regulated pressure P of the proportional servo valve 526CCan be expressed as an average control pressure
The pressure P can be set by adjusting the proportional pressure reducing valve 521 in combination with the sum of the incremental control pressure Δ PDSo that
(PLThe actual loading pressure of building 1 for a certain jacking point) so that the control pressure P is adjusted only by means of the proportional servo valve 526CWhen Δ P > 0, building 1 will rise, when Δ P < 0, building 1 will fall back, and when Δ P equals 0, building 1 can be in hovering state, and real-time feedback is performed through displacement sensor 525, thereby implementing position closed-loop control of multi-point force control.
In order to reduce the static friction force and the horizontal thrust force of the translation of the building, the suspension support sliding device for the translation of the building provided by the embodiment is provided with an antifriction sliding plate with a small friction coefficient, and as shown in fig. 2, the bottom of the spherical deviation rectifying saddle 6 is provided with a groove; an antifriction sliding plate 7 is arranged in the groove; the antifriction skid plate 7 is slidably disposed on the lower track beam 3. Considering that the friction force of the spherical deviation rectifying saddle 6 is large in the translation process of the building 1, the antifriction sliding plate 7 is arranged, the antifriction sliding plate 7 is made of composite materials, the compression strength is high, the friction coefficient is small (the static friction and the dynamic friction coefficient are both loaded by about 0.05), and the antifriction sliding plate 7 carries with the load to slide on the lower track beam 3, so that the horizontal thrust force of the building during translation is greatly reduced, the lateral stress of the building during translation is effectively reduced, and the stability of the structure of the building is ensured. When the friction sliding plate is invalid due to expiration of service life, the friction sliding plate only needs to be replaced periodically without replacing the spherical deviation rectifying saddle 6 or other components, so that the service life of the suspension support sliding device is further prolonged, and the economy of the suspension support sliding device is improved.
