Alternatively, the second locking piece is a screw, a bolt or a latch.

[0038] As shown in the drawings, Figure 6 In this embodiment, a first reinforcing rib 317 is connected between the first cross bar 314 and the first slide seat to increase the rigidity of the lifting frame 31 and prevent the first cross bar 314 from deforming.

[0039] As shown in the drawings, Figure 6As shown, in the embodiment, three first longitudinal beams 313 are arranged on the slide bar 312 at intervals, and two first cross bars 314 are arranged on each first longitudinal beam 313 at intervals, so as to set three commonly used support heights. When the height of the lower surface of the top supporting plate 101 of the support pier 100 is different from the commonly used support height, the relative position of one of the first longitudinal beams 313 and the vertical plate 315 is adjusted, so as to reduce the time for on-site adjustment and improve the carrying efficiency. It can be understood that the number of the first longitudinal beams 313 can also be one, two, four or more, which can be increased or decreased according to actual use requirements.

[0040] As shown in Figure 5 and Figure 7 As shown, in the embodiment, the lever mechanism 32 includes a rod body 321, an arc-shaped block 322 arranged on the first end of the rod body 321 and used for cooperating with the lifting frame 31 to jacking the support pier, a pedal 323 arranged on the second end of the rod body 321, a hinge shaft 324 used for hingedly connecting the rod body 321 and the frame 1, and a limiting frame 325 arranged on the rod body 321. The distance between the pedal 323 and the hinge shaft 324 is greater than the distance between the arc-shaped block 322 and the hinge shaft 324. The two second cross beams 13 are respectively provided with first ear seats 18, and the two ends of the hinge shaft 324 are respectively connected with the first ear seats 18. The rod body 321 can rotate around the hinge shaft 324 as the axis. In use, the two first cross bars 314 abut against the lower surface of the top supporting plate 101 of the support pier 100, and the arc-shaped block 322 abuts against the outer cylindrical surface of the support pier 100. The pedal 323 is stepped on to make the arc-shaped block 322 cooperate with the lifting frame 31 to jacking the support pier 100. The arc-shaped block 322 cooperates with the lifting frame 31 to clamp the support pier 100, so as to avoid shaking and falling of the support pier 100 during the carrying process, thereby improving the safety. The structure is simple, labor-saving, and low in production cost. In addition, the support pier transfer device is also suitable for special-shaped workpieces or tooling, and the support surface shape of the arc-shaped block 322 can be adjusted accordingly. Optionally, the limiting frame 325 includes fourth longitudinal beams 3251 and fourth cross beams 3252. The two fourth longitudinal beams 3251 and the two fourth cross beams 3252 constitute the limiting frame 325. The pedal 323 is connected with one of the fourth longitudinal beams 3251 through the rod body 321, and the arc-shaped block 322 is connected with the other fourth longitudinal beam 3251 through the rod body 321. The two ends of the hinge shaft 324 are respectively connected with the first ear seats 18 through the two fourth cross beams 3252, so as to avoid the limiting frame 325 from moving along the extension direction of the fourth longitudinal beam 3251, thereby ensuring the stability of the lever mechanism 32. Optionally, a second reinforcing rib 327 is connected between the rod body 321 and the fourth longitudinal beam 3251.

[0041] In this embodiment, the inner wall surface of the arc-shaped block 322 is provided with a soft pad. On the one hand, the soft pad can make the arc-shaped block 322 fit the outer cylindrical surface of the support pier, so as to avoid scratching the outer cylindrical surface of the support pier; on the other hand, the soft pad can increase the friction between the arc-shaped block 322 and the outer cylindrical surface of the support pier, so as to avoid the support pier from slipping off.

[0042] As shown in Figure 8 , Figure 9 and Figure 10 , in this embodiment, the limiting mechanism 4 includes a lever 41, a limiting plate 42 provided on the lever 41, a return spring 43 for connecting the limiting plate 42 and the rod body 321, and a pin shaft 44 for hingedly connecting the limiting plate 42 and the frame 1. The limiting plate 42 is provided with a bayonet 421 adapted to the limiting frame 325. The fourth cross beam 3252 or the rod body 321 is provided with a lug 326. The two ends of the return spring 43 are connected to the lug 326 and the limiting plate 42, respectively. The second longitudinal beam 14 is provided with a second lug seat 19. The limiting plate 42 is hingedly connected to the second lug seat 19. When the support pier transfer device is in the initial state, the lifting frame 31 is pressed on the first end of the arc-shaped block 322 or the rod body 321. The bayonet 421 of the limiting plate 42 clamps the limiting frame 325, so that the lever mechanism 32 is in a balanced state. When in use, the staff first pushes the lever 41 forward. The bayonet 421 of the limiting plate 42 is separated from the limiting frame 325. Due to the action of gravity, the lifting frame 31 presses the first end of the arc-shaped block 322 or the rod body 321 and descends at the same time. The second end of the rod body 321 drives the pedal 323 to be raised. At this time, the return spring 43 is stretched. The staff keeps the state of pushing the lever 41 forward. The frame 1 moves forward, so that the arc-shaped block 322 abuts against the outer cylindrical surface of the support pier 100. The lifting frame 31 is naturally forked into the lower part of the supporting plate 101. The pedal 323 is stepped on. The arc-shaped block 322 cooperates with the lifting frame 31 to jack up the support pier 100. After the support pier 100 is separated from the ground, the lever 41 is loosened. The limiting plate 42 is reset under the elastic force of the return spring 43. The bayonet 421 clamps the limiting frame 325, so as to limit the lever mechanism 32. The lever 41 is reset with the limiting plate 42. The staff pushes the frame 1 to transfer the support pier 100 to the target position. The pedal 323 is stepped on. The lever 41 is pushed forward again. The bayonet 421 of the limiting plate 42 is separated from the limiting frame 325. The arc-shaped block 322 is slowly lowered, so that the support pier 100 can be stably placed at the specified position. The stable lifting and falling of the support pier 100 can be realized. The support pier 100 is prevented from dragging and damaging the epoxy resin floor paint of the factory building ground, so as to save the ground maintenance cost.

[0043] As shown in Figure 4 , in this embodiment, the frame 1 is provided with a handle 12, which is convenient for the operator to push and pull the frame 1.

[0044] The above merely describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes.
