[0029] Specifically, the support assembly 29 includes a triangular plate 291. The triangular plate 291 is fixed on both sides of the upper end between the connecting plate 11 and the fixing box 21. Two horizontal bars 292 are fixed on the upper side of one end of the fixing box 21. A diagonal tie rod 293 is fixed at the lower end between the horizontal bar 292 and the fixing box 21. Several support rollers 295 are arranged between the two horizontal bars 292. The support rollers 295 and the horizontal bars 292 are connected by a rotating shaft 294.
[0030] By adopting the above technical solution, when the station frame 7 moves, the lower end of the station frame 7 drives the support roller 295 to rotate on the crossbar 292 through the rotating shaft 294. Several support rollers 295 can support the station frame 7, thereby making the movement of the station frame 7 more stable. By fixing the diagonal tie rod 293 between the crossbar 292 and the fixed box 21, and fixing the triangular plate 291 between the connecting plate 11 and the fixed box 21, the relationship between the crossbar 292 and the fixed box 21, as well as between the connecting plate 11 and the fixed box 21, is made more stable.
[0031] Specifically, the rotating rod 28 and the fixed box 21 are rotatably connected by bearings, and the connecting block 24 and the rack plate 26, as well as the connecting block 24 and the station frame 7, are all spot welded together.
[0032] By adopting the above technical solution, the rotating rod 28 can rotate in the fixed box 21, and the spot welding makes the connection block 24 and the rack plate 26, as well as the connection block 24 and the station frame 7, more secure.
[0033] Specifically, the lower end of the station frame 7 is tangent to the upper end of the fixing box 21, and the side of the slide plate 22 is tangent to the inner wall of the fixing box 21.
[0034] By adopting the above technical solution, the station frame 7 moves more stably on the fixed box 21, and the slide plate 22 slides more stably inside the fixed box 21.

[0036] By adopting the above technical solution, the support roller 295 can support the movement of the station frame 7, and the rack plate 26 will not rub against the lower end of the support roller 295 when it moves.
[0037] In this embodiment, when using the safety lifting device for the sewage treatment tank, the device is installed in a suitable position, and the operator enters the station frame 7. The motor 9 is turned on, driving the lead screw 6 to rotate, which in turn raises and lowers the connecting plate 11. The connecting plate 11 then lowers the station frame 7 into the tank body 1. Simultaneously, the moving cart 8 is pushed, causing the station frame 7 to move longitudinally. The positioning plate 5 slides in the fixed plate 4 on the lower side of one end of the tank body 1. The motor 27 is turned on, driving the rotating rod 28 and the rack roller 210 to rotate. The rotation of the rack roller 210 causes the rack plate 26 and the sliding plate 22 to move. The movement of the rack plate 26, through the connecting block 24, causes the upper station frame 7 to move. The connecting block 24 moves in the sliding groove 25 at the upper end of the fixed box 21. When the frame 7 moves, one end of the rack plate 26 moves out of the fixed box 21 through the through hole 23. The station frame 7 can be adjusted laterally by setting the adjustment component 2, thereby increasing the working range of the staff. When the station frame 7 moves, the lower end of the station frame 7 drives the support roller 295 to rotate on the crossbar 292 through the rotating shaft 294. Several support rollers 295 can support the station frame 7, thereby making the movement of the station frame 7 more stable. By fixing the diagonal tie rod 293 between the crossbar 292 and the fixed box 21, and fixing the triangular plate 291 between the connecting plate 11 and the fixed box 21, the relationship between the crossbar 292 and the fixed box 21, as well as between the connecting plate 11 and the fixed box 21, is made more stable.

[0047] Specifically, the storage box 36 is fixed to the frame 7 by bolts, and several partitions 37 are equidistantly snapped into the storage box 36.
[0048] By adopting the above technical solution, the bolt connection facilitates the assembly and disassembly of the storage box 36, and several partitions 37 can divide the internal storage space of the storage box 36 at equal intervals.
[0049] In this embodiment, the baffle 31 is pulled out from the opening 32 by the lifting ring 35, and the staff can enter the station frame 7 through the opening 32. Then the baffle 31 is put back into the opening 32. The protrusion 33 on the upper side of one end of the baffle 31 enters the groove 34 to limit and fix the baffle 31. The baffle 31 seals the opening 32. The setting of the blocking component 3 makes it easy for the staff to enter the station frame 7 without the need for the staff to climb over to enter the station frame 7, thus improving safety. The storage box 36 is set at one end inside the station frame 7 to facilitate the storage of the staff's work tools.
