[0026] The operator uses a crane to place the base plate 1 and the gantry truss body 2 at the position where they need to be installed. Then, during the process of installing the base plate 1 and the gantry truss body 2, when it is necessary to fine-tune the position of the base plate 1 and the gantry truss body 2, the motor 14 can be driven, and then the output end of the motor 14 will drive the gear 2 10 to rotate, because the surface transmission connection of the gear 2 10 and the gear 1 9 is connected with the transmission gear ring 11, and the surfaces of the gear 2 10 and the gear 1 9 are meshed with the inside of the transmission gear ring 11, and then when the gear 2 10 rotates, it will drive the transmission gear ring 11 and the gear 1 9 to rotate. During the rotation of the transmission gear ring 11, the transmission gear ring 11 will drive the connecting plate 12 and the connecting plate 2 13 to move relative to each other, and then the connecting plate 12 and the connecting plate 2 13 will rotate. At the same time, the two extrusion blocks 8 are driven to move relative to each other, and then the bottom end of the extrusion block 8 will contact the top end of the contact block 6, and the extrusion block 8 will squeeze the contact block 6 to descend, and when the contact block 6 descends, the mounting plate 4 and the universal wheel 5 will be driven to descend, and when the mounting plate 4 descends, the spring 3 will be stretched, and then the surface of the universal wheel 5 will contact the ground, and the universal wheel 5 will lift the bottom plate 1 and the gantry truss body 2, and then the bottom end of the gantry truss body 2 will be away from the ground, and then the operator can push the bottom plate 1 or the gantry truss body 2, and then the universal wheel 5 will rotate, and during the rotation process, the bottom plate 1 and the gantry truss body 2 will be driven to move, so that the bottom plate 1 and the gantry truss body 2 can be fine-tuned, so that the bolt groove 18 can be aligned with the threaded hole on the ground;

[0027] After alignment, the motor 14 can be driven again to make the gear 2 10 rotate in the opposite direction, and the gear 2 10 will drive the transmission gear ring 11 and the gear 1 9 to rotate in the opposite direction, and then the transmission gear ring 11 will drive the connecting plate 1 12 and the connecting plate 2 13 to move towards each other, and then the extrusion block 8 will move away from the top of the contact block 6, and then the compressed spring 3 will pull the mounting plate 4 and the universal wheel 5 to move upward, and then the mounting plate 4 and the universal wheel 5 will shrink to the inside of the bottom plate 1, and then the bottom end of the bottom plate 1 will contact the ground again, and the bottom end of the bolt groove 18 will contact the threaded hole on the ground, and then the operator can fix the bottom plate 1 and the gantry truss body 2;

[0028] like Figure 6 and Figure 7 As shown, the left and right sides of the bottom plate 1 are provided with slide grooves 15, the left and right ends of the mounting plate 4 are internally rotatably connected with pulleys 16, and the pulleys 16 can roll inside the slide grooves 15, and the bottom ends of the gears 1 9 and 2 10 are fixedly installed with support plates 17, the size of the support plates 17 is larger than the size of the gears 1 9 and 2 10, and the top end of the support plates 17 is in contact with the bottom end of the transmission gear ring 11;

[0029] Through the design of the slide groove 15 and the pulley 16, since the surface of the pulley 16 fits the inner wall of the slide groove 15, when the mounting plate 4 moves, the slide groove 15 will rotate, and then the slide groove 15 will limit the mounting plate 4, and the universal wheel 5 will roll, so that the mounting plate 4 can move more smoothly; through the design of the support plate 17, when the gear 1 9 and the gear 2 10 rotate, the support plate 17 will rotate along with it, because the size of the support plate 17 is larger than the gear 1 9 and the gear 2 10, and the top of the support plate 17 is in contact with the bottom end of the transmission gear ring 11, the transmission gear ring 11 can be supported to prevent the transmission gear ring 11 from being separated from the surfaces of the gear 1 9 and the gear 2 10 during the rotation process;

[0030] like Figure 2 and Figure 3 As shown, a fixing bolt 19 is arranged inside the bolt groove 18, and the number of the fixing bolts 19 is four and evenly distributed on the surface of the bottom plate 1. A reinforcing plate 20 is fixedly installed on the top of the bottom plate 1, and the number of the reinforcing plates 20 is four and is designed around the surface of the bottom plate 1;

[0031] Through the design of the fixing bolts 19, four fixing bolts 19 can be inserted into the bolt grooves 18 at the same time, and then the fixing bolts 19 can be rotated, and then the fixing bolts 19 will enter the bolt grooves 18 and the threaded holes, so as to fix the bottom plate 1 and the gantry truss body 2; through the design of the reinforcing plate 20, since the reinforcing plate 20 is arranged on the surface of the bottom plate 1, the rigidity of the gantry truss body 2 can be increased;

[0032] like Figure 5 and Figure 6 As shown, one side of the bottom end of the extrusion block 8 is designed with an inclined surface, and both sides of the top end of the contact block 6 are designed with inclined surfaces, and the inclined surface at the bottom end of the extrusion block 8 and the inclined surface at the top end of the contact block 6 are parallel to each other, the limiting rod 7 is designed to be cylindrical, and the surface is designed to be smooth, and the limiting rod 7 is designed to be transversely symmetrical about the center of the extrusion block 8;

[0033] Through the design of the contact block 6 and the extrusion block 8, when the bottom end of the extrusion block 8 contacts the top end of the contact block 6, since the bottom end of the extrusion block 8 is designed as an inclined surface, and the top end of the contact block 6 is designed as an inclined surface, and they are parallel to each other, the friction and resistance between the extrusion block 8 and the contact block 6 can be reduced, so that it is convenient for the extrusion block 8 to squeeze the contact block 6 down; through the design of the limit rod 7, when the extrusion block 8 moves, the extrusion block 8 will slide on the surfaces of the two limit rods 7. Since the surface of the limit rod 7 is designed to be smooth, the friction between the limit rod 7 and the limit rod 7 can be reduced, so that the extrusion block 8 moves more smoothly;

[0034] The working principle and use process of this utility model:

[0035] First, the operator can use a crane to lift the bottom plate 1 and the gantry truss body 2, and then place the bottom plate 1 and the gantry truss body 2 at the position where they need to be installed. During the installation process, when it is necessary to fine-tune the position of the bottom plate 1 and the gantry truss body 2, the motor 14 can be driven to rotate the gear 2 10, and then the gear 2 10 will drive the transmission gear ring 11 and the gear 1 9 to rotate, and the connecting plate 1 12 and the connecting plate 2 13 will drive the two extrusion blocks 8 to move relative to each other, and then the two extrusion blocks 8 will contact the top of the contact block 6, and will squeeze the contact block 6, the mounting plate 4 and the universal wheel 5 to descend, and then the spring 3 will be stretched, and then the surface of the universal wheel 5 will contact the ground, and then the bottom plate 1 and the gantry truss body 2 can be pushed to rotate the universal wheel 5, and through the rotation of the universal wheel 5, the position of the bottom plate 1 and the gantry truss body 2 can be fine-tuned, and then the bolt slot 18 is aligned with the threaded hole on the ground;

[0036] After the bolt groove 18 is aligned with the threaded hole on the ground, the motor 14 can be driven again to make the gear 2 10 rotate in the opposite direction, and then the gear 2 10 will drive the transmission gear ring 11 and the gear 1 9 to rotate in the opposite direction, and then the connecting plate 1 12 and the connecting plate 2 13 will drive the extrusion block 8 to move towards each other, and the extrusion block 8 will move away from the top of the contact block 6, and then the compressed spring 3 will pull the mounting plate 4 and the universal wheel 5 to rise, and then the mounting plate 4 and the universal wheel 5 will shrink to the inside of the bottom plate 1, and then the fixing bolts 19 can be inserted into the bolt groove 18 and the threaded hole to fix the bottom plate 1 and the gantry truss body 2.
