The mounting frame 10 is fixedly installed on the bottom end of the moving rod 6. Through the setting of the elastic component, when the moving wheel 16 is retracted, the moving wheel 16 is driven to separate from the ground, so that the base 1 is in contact with the ground. The mounting frame 4 is provided with a mounting frame 10 through the elastic component. The mounting frame 10 is provided with a locking component. The locking component includes a limit block 11. The limit block 11 is slidably provided inside the mounting frame 10. The limit block 11 overlaps with the mounting frame 4. A transverse spring 12 is fixedly provided between the facing surfaces of the limit block 11. A locking block 13 is overlapped on the top of the limit block 11. A blocking plate is fixedly provided inside the mounting frame 4, and the number of the blocking plates is several and arranged in a row. The symmetrical distribution is achieved by setting the blocking plate so that when the limit block 11 compresses the transverse spring 12 and shrinks into the installation frame 10, there will be no shaking or deviation, so that the limit block 11 can be inserted into the bottom of the locking block 13, avoiding the limit block 11 and the locking block 13 from being locked and misaligned. The bottom of the limit block 11 is an inclined surface, and the top of the locking block 13 is an inclined surface. The limit block 11 and the locking block 13 are both made of metal. Through the inclined surface, the locking block 13 can squeeze the limit block 11, so that the limit block 11 compresses the transverse spring 12, thereby shrinking the limit block 11 into the installation frame 10, so that the limit block 11 can move to the bottom of the locking block 13, thereby facilitating the limit block 11 to be inserted into the bottom of the locking block 13, and the metal material The limit block 11 and the locking block 13 are not prone to breakage. The locking block 13 is fixedly mounted on the inner wall of the mounting frame 4. Through the setting of the locking assembly, the position of the moving wheel 16 is locked after the moving wheel 16 contacts the ground. A pushing assembly is arranged inside the mounting frame 4. A mounting column 15 is fixedly arranged at the bottom of the mounting frame 10. A moving wheel 16 is fixedly arranged at the bottom of the mounting column 15. The moving rod 6 is pushed by the limit plate 7 to drive the moving ring 9 to stretch the vertical spring 8, so that the mounting frame 10 drives the limit block 11 to insert into the bottom of the locking block 13, so that the mounting frame 10 pushes the moving wheel 16 to contact the ground through the mounting column 15, and the pier can be moved, and then the pushing assembly pushes the limit block 11 to move out from the bottom of the locking block 13.The vertical spring 8 drives the moving rod 6 to reset through the moving ring 9, so that the installation frame 10 drives the moving wheel 16 to separate from the ground through the installation column 15, so as to facilitate the movement of the piers. The movable piers are convenient for placing the box beam, avoiding the need to use too much concrete to cast the piers, resulting in a lot of time spent on the subsequent removal of the piers. Different numbers of piers can be placed according to the specifications of the box beam, and the piers can be recycled.
[0021] Specifically, the pushing component includes a moving plate 17, which is slidably arranged inside the mounting frame 4, and a rectangular baffle 14 is fixedly arranged at the bottom of the moving plate 17. A placement groove for placing the rectangular baffle 14 is opened inside the mounting frame 4. The moving plate 17 is pushed to drive the rectangular baffle 14 to move, so that the moving plate 17 pushes the limit block 11 away from the bottom of the locking block 13, thereby facilitating the moving rod 6 to drive the limit block 11 to move to the top of the locking block 13 through the mounting frame 10, thereby facilitating the retraction of the moving wheel 16.
