The eleventh step, shown in fig. 15, continues to raise the SPMT2 bed height until the main upright 301 of the structure 3 being weighed disengages from the building pier 4. The weighed structure 3 is shipped with SPMT2 to complete the shipment and then withdrawn from SPMT 2.
In the twelfth step, as shown in fig. 5-6, the weight sensor 105 on the vehicle-mounted pad pier 201 is removed and recovered, the vehicle-mounted pad pier 201 on the vehicle plate of the SPMT2 is removed and recovered, and the whole construction process is finished.
In the hydraulic sensor mode:
as shown in fig. 16-17, according to the requirement for the arrangement of the vehicle-mounted pad pier 201 in the corresponding weighing scheme, the vehicle-mounted pad pier 201 is arranged on the SPMT2 vehicle board, the length direction of the vehicle-mounted pad pier 201 and the length direction of the SPMT2 vehicle board are perpendicular to the vehicle-mounted pad pier and are only used for adjusting the distance between the SPMT vehicle board and the bottom main beam 302 of the structure to be weighed, and if the height of the bottom main beam 302 of the structure to be weighed is appropriate, the vehicle-mounted pad pier 201 can be omitted.
In the second step, shown in figures 18-20, the SPMT2 is activated and travels to just under the structure 3 to be weighed. At this time, the bottom main beams 302 of the structure 3 to be weighed of the on-board pad pier 201 are aligned up and down.
Third, as shown in fig. 21, the hydraulic sensors 104 are installed on the dedicated service interface of the SPMT2 hydraulic suspension system, 2 hydraulic sensors being installed in groups.
Fourthly, as shown in fig. 22, the displacement sensor 106 is arranged at the lower part of the main upright 301 of the structure 3 to be weighed, close to the building buttress 4; a standard skid 202 is placed onto the truck-mounted pad 201.
And fourthly, as shown in figure 1, performing system connection debugging according to the system arrangement requirements, and performing weighing information setting and sensor connection relation initial value confirmation through the setting and monitoring software of the upper computer.
In a fifth step, pre-lift is performed, as shown in FIGS. 23-24. In the lifting process, the safety of the structure 3 to be weighed and the weighing device 1 is checked and confirmed to be normal.
Sixth, weigh and lift, as shown in fig. 23-24. At least three satisfactory weighing results were obtained by lifting the SPMT2 and lowering the operation.
And seventhly, removing and recovering hardware equipment such as the hydraulic sensor 104, the displacement sensor 106, the cable on-site patrol instrument 103 and the like as shown in figure 1.
Eighth, as shown in fig. 25, lift SPMT2, ship the weighed structure 3 with SPMT2 to complete the shipment, and then evacuate SPMT 2. And finishing the whole construction process.
The lifting control can be carried out by utilizing the self-carried hydraulic system of the self-propelled module transport vehicle, so that the manufacturing of a weighing pad pier and the arrangement and dismantling work of a hydraulic jack of the weighing pad pier in the traditional weighing mode are avoided; the self-propelled module transport vehicle can perform the function of hydraulic compensation and automatic adjustment of the horizontal state of the vehicle plate, so that the synchronism of a weighing system is ensured, and the requirement on the ground flatness of a symmetrical weight area is eliminated; the contact between different hardware and a weighed structure can be completed through the lifting and lowering of the SPMT2 vehicle plate and the placement and the removal of the jacking cushion plate 203 and the standard skid 202; after the module is weighed, the self-propelled module transport vehicle can be directly used for transporting and loading the ship; for the combined built module structure, the three processes of module shifting, weighing and shipping are realized at one time by using the invention, and the material labor cost and the project construction period are saved. In addition, the invention has double working modes of the weight sensor 105 and the hydraulic sensor 104, and the precision meets the weighing requirements of various levels.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
