Subsequently, an external driving device is used to make the screw rod 5 rotate forward and reverse, driving the corresponding reciprocating movement of the moving seat 6, and cooperating with the pushing unit 7 and the lifting assembly 10 to realize driving the cutting unit 11 to move and cut at any position on the steel grating.

[0029] For further information, see Figure 2 - Figure 4 The pushing unit 7 includes a threaded barrel 12 fixed to the outer side of the moving seat 6, a threaded rod 13 is inserted into the inner thread of the threaded barrel 12, a moving plate 14 is rotatably installed on the outer side of the threaded rod 13 through a bearing, a telescopic rod 15 is fixed between the moving plate 14 and the moving seat 6, a driving motor 16 is fixed on the moving plate 14, and a driving gear 17 meshing with each other is fixed on the outer end of the driving motor 16 and the screw rod 5, and a pushing assembly 18 fixed to the cutting seat 8 is installed on the moving plate 14;

[0031] The pushing principle of the pushing unit 7 is: the threaded rod 13 is driven to rotate by the driving motor 16, and the threaded rod 13 rotates and moves in the threaded cylinder 12, so that the moving plate 14 follows the extension and contraction of the threaded rod 13 and moves accordingly. At the same time, the position of the cutting seat 8 is adjusted by the action of the electric push rod 19;

[0032] It should also be noted that the movable plate 14 is rotatably connected to the threaded rod 13 through a bearing, so that the threaded rod 13 can rotate normally. At the same time, when the threaded rod 13 moves in a telescopic manner, the movable plate 14 will be driven to move accordingly.

[0033] For further information, see Figure 5 and Figure 6 A track groove 21 is provided on the cutting seat 8, a slider 22 plugged into the track groove 21 is fixed on the mounting seat 9, and the slider 22 is docked with the lifting assembly 10. The design of the slider 22 and the track groove 21 makes the sliding between the mounting seat 9 and the cutting seat 8 more stable.

[0034] For further information, see Figure 4 - Figure 6 The lifting assembly 10 includes a lifting rod 23 rotatably mounted in the track groove 21, the lifting rod 23 is threadedly plugged into the slider 22, a lifting motor 24 is fixed to the cutting seat 8 through a motor seat, and the output end of the lifting motor 24 is fixed to the outer end of the lifting rod 23 through a coupling;

[0035] The lifting motor 24 rotates to drive the lifting rod 23 to rotate, so that the slider 22 threadedly connected thereto rotates accordingly, and then the slider 22 slides in the track groove 21 .

[0036] For further information, see Figure 5 and Figure 6 The cutting unit 11 includes a cutting motor 25 fixed on a mounting seat 9, the cross-sectional shape of the mounting seat 9 is L-shaped, a cylinder 26 is fixed to the outer end of the mounting seat 9, a mounting plate 27 is fixed to the outer side of the cylinder 26, a main gear 28 and a secondary gear 29 are rotatably mounted on the mounting plate 27, the output end of the cutting motor 25 is fixed to the gear shaft of the main gear 28, a rotating arm 30 is rotatably mounted on the outer side of the cylinder 26, a large cutting wheel 32 and a small cutting wheel 33 are respectively arranged at both ends of the rotating arm 30, linkage components 31 are respectively installed at both ends of the rotating arm 30, and the large cutting wheel 32 and the small cutting wheel 33 are respectively driven to rotate by two sets of linkage components 31, and a locking member 34 is installed on the rotating arm 30;

[0037] The linkage assembly 31 includes a linkage gear 35 rotatably mounted on the rotating arm 30, the linkage gear 35 is adapted to the secondary gear 29, a cutting gear 36 meshing with the linkage gear 35 is rotatably mounted on the rotating arm 30, a docking post 37 is fixed on the cutting gear 36, the large cutting wheel 32 is sleeved on the outside of the docking post 37 and positioned by tightening the cover, and the docking post 37 of the other cutting gear 36 is docked with the small cutting wheel 33;

[0038] Meanwhile, the locking member 34 includes two locking rings 38 fixed on the rotating arm 30 , and a locking rod 39 is inserted into the locking ring 38 , and the locking rod 39 is threadedly inserted into the mounting seat 9 .

[0039] The principle of cutting the steel grating by the cutting unit 11: Due to the different lengths and widths between the staggered grid plates on the steel grating, during the process of cutting special-shaped openings, when cutting the area with small spacing alone, it is difficult for the large cutting wheel 32 to cut off a connection, so it needs to be converted into a small cutting wheel 33. During the conversion process, the personnel first unscrew the locking rod 39, and then drive the rotating arm 30 to rotate. After rotating until the linkage gear 35 is engaged with the secondary gear 29, the personnel inserts the locking rod 39 into the locking ring 38, and docks it with the mounting seat 9 to lock and position the rotating arm 30. Then, under the action of the cutting motor 25, the main gear 28 and the secondary gear 29 are driven to rotate, and the linkage gear 35 engaged with the secondary gear 29 rotates synchronously, driving the cutting gear 36 to rotate, thereby driving the large cutting wheel 32 or the small cutting wheel 33 to rotate, meeting the opening cutting of steel gratings with different spacings.

[0040] It should be noted that both the large cutting wheel 32 and the small cutting wheel 33 can be removed from and installed on the docking column 37 on the cutting gear 36 .

[0041] Example 2: Please refer to Figure 1 , Figure 4 as well as Figure 7 This embodiment further explains the first embodiment, and the difference lies in the expansion of one of the implementation modes of the positioning unit 3.

[0042] Specifically, the positioning unit 3 includes a chassis 40, a positioning rod 41 threadedly connected to the docking hole 2 is fixed at the bottom of the chassis 40, a plug-in column 42 is rotatably installed on the chassis 40, a socket compatible with the steel grating is opened in the plug-in column 42, and an abutment cap 43 is threadedly inserted on the outer side of the plug-in column 42. In order to facilitate the rotation operation of the chassis 40, an anti-skid groove is opened on the outer side of the chassis 40. The design of the anti-skid groove facilitates personnel to operate the rotation of the chassis 40.

[0043] In this solution, the personnel hold the chassis 40, align the positioning rod 41 with the docking hole 2 and screw it in to fix it. Then, the steel grating is inserted into the socket on the plug-in column 42, and the abutting cap 43 is screwed on to achieve the positioning of the steel grating. By plugging several positioning units 3 into different docking holes 2, the positioning requirements of steel gratings with different rules can be met.
