[0014] A method for using a material storage and transfer platform for safe construction of a hub interchange super-large bridge, the steps are as follows:

[0015] Step 1: Transporting materials

[0016] The third motor rotates the transmission wheel, and the round pin on the transmission wheel contacts and connects with the radial groove of the groove wheel.

9. A method for using the material storage and transfer platform for safe construction of a hub interchange super-large bridge according to claim 8, characterized in that: Here are the steps: Step 1: Transporting materials The third motor (406) rotates the transmission wheel (405), and the round pin on the transmission wheel (405) contacts and connects with the radial groove of the groove wheel (403). The transmission wheel (405) rotates, and the round pin gives thrust to the radial groove of the groove wheel (403), so that the groove wheel (403) rotates, and the toggle rod (404) fixedly connected to the groove wheel (403) rotates at the same time. The toggle rod (404) toggle the material to move on the conveyor belt (401), and the conveyor belt (401) moves with the movement of the material. The toggle rod (404) toggle the material to the lower end of the clamp assembly (3) to facilitate the clamping of the clamp assembly (3); Step 2: Clamp the material The piston rod of the second hydraulic telescopic rod (301) extends outward to the two electric clamps (303) to clamp and fix the material. Then, the second motor (305) is used to rotate the worm (304), thereby realizing the rotation of the worm (304). The worm (304) drives the worm wheel (306) to rotate, and the worm wheel (306) drives the locking rod (307) to swing, so that the locking rod (307) rotates through a certain angle, and the fixing hook (308) on the locking rod (307) rotates toward the fixing rod (312). At this time, the lower end fixedly connected to the other end of the locking rod (307) The baffle plate (313) rotates in the opposite direction to the fixing hook (308) until the surface of the fixing hook (308) contacts the fixing rod (312). The lower baffle plate (313) is now located below the clamp frame (302). The lower baffle plate (313) can prevent the material from falling and hitting the base (1). The locking block (311) contacts the other side of the fixing rod (312) to complete the locking of the fixing hook (308). The descending member (309) drives the locking block (311) to move downward along the vertical guide groove (314) until the hook plate (315) presses down to limit the clamping plate (316). Step 3: Transfer The first motor (202) provides energy for the rotation of the rotating wheel (201), driving the rotating wheel (201) to rotate. The rotation angle of the rotating wheel (201) is 270 degrees. The rotation of the rotating wheel (201) drives the first hydraulic telescopic rod (203) to rotate, so that the entire clamp assembly (3) and the clamped material rotate at the same time. The first hydraulic telescopic rod (203) can be vertically extended to adjust the height of the material. The installation position of the mobile frame (204) and the first hydraulic telescopic rod (203) is vertically installed. The mobile frame (204) provides a place for the movement of the clamp assembly (3). The screw motor (205) can be extended and retracted. The screw rod (206) moves in the same direction as the extension direction. The screw rod (206) pulls the second hydraulic telescopic rod (301) to slide in the mobile frame (204), so as to realize the movement of the clamp assembly (3) on the mobile frame (204) to adjust the horizontal position of the material relative to the target position. Step 4: Decentralization When the material is adjusted to the position just above the target position, the downward member (309) drives the locking block (311) to reset vertically, the clamping plate (316) releases the restriction, the second motor (305) drives the worm (304) to rotate in the opposite direction, the worm (304) drives the worm wheel (306) to rotate, the worm wheel (306) drives the locking rod (307) and the lower baffle (313) to reset in the opposite direction to the initial state, the extension length of the first hydraulic telescopic rod (203) and the second hydraulic telescopic rod (301) is adjusted, the material is lowered to the target position, the electric clamping plate (303) is reset, and the material is released; Repeat steps 1 to 4 until all materials have been stored and transferred.
