Detailed Embodiment

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0027] Referring to the attached Figure 1 - attached Figure 5 , the present utility model provides a cutting device for steel of electric power transmission towers, including a cutting member for cutting steel provided outside the material table 1;

[0028] The cutting member includes an air duct 2 fixedly connected to one side of the bottom end of the material table 1, and a fan 3 is installed inside the air duct 2. The outer end of the air duct 2 away from the material table 1 is successively provided with a top pipe 4, a corrugated pipe 5 and a bottom pipe 6 from top to bottom. The bottom end of the bottom pipe 6 is fixedly connected to the air duct 2. A housing 7 is sleeved at the bottom of the end of the top pipe 4 away from the corrugated pipe 5. A cutting wheel 8 is installed inside the housing 7 and is movably connected by a rotating shaft. A servo motor 9 for driving the cutting wheel 8 to cut steel is installed on the front side of the housing 7.

[0029] During use, the servo motor 9 is used to drive the cutting wheel 8 to rotate, and the steel is cut by the cutting wheel 8. At the same time, the fan 3 is started to suck the air outside the material table 1 into the material table 1. Among them, since a collection box 10 is provided inside the material table 1, and a filter plate 11 is embedded on one side of the collection box 10 corresponding to the air duct 2. A material opening 12 is provided on the side of the material table 1 away from the air duct 2. One end of the collection box 10 away from the filter plate 11 penetrates through the material opening 12 and extends to the outside of the material opening 12. In this way, the debris generated when the cutting wheel 8 cuts the steel can be centrally collected into the collection box 10 and filtered by the filter plate 11, so that the filtered air can be transported to the inside of the housing 7 through the bottom pipe 6, the corrugated pipe 5 and the top pipe 4, so as to cool and dissipate heat from the cutting wheel 8, avoid cracking due to overheating, and at the same time, the debris adhered to the cutting wheel 8 can be blown away by the air flow. Moreover, the air flow from top to bottom can blow the debris into the collection box 10 inside the material table 1, avoiding debris splashing and polluting the working environment.

[0030] To facilitate the cutting wheel 8 to cut steel with different thicknesses, the height of the cutting wheel 8 needs to be adjusted. As Figure 1 and Figure 2 shown, movable plates 13 are installed on both sides of the top end of the material table 1 and are movably connected by rotating shafts. Adjustment holes 14 are provided on the outer part of the top end of the movable plates 13, and an adjustment plate 15 for connecting the housing 7 is provided inside the adjustment holes 14. A fixed seat 16 is provided at the bottom of the end of the adjustment plate 15 away from the housing 7. The fixed seat 16 is installed on the side of the bottom end of the movable plate 13 away from the material table 1, and a first electric push rod 17 for connecting the adjustment plate 15 is installed on the top of the fixed seat 16. The telescopic movement of the first electric push rod 17 drives the adjustment plate 15 to move up and down, and the adjustment plate 15 drives the cutting wheel 8 in the housing 7 to move, so as to realize the height adjustment of the cutting wheel 8, facilitate the cutting wheel 8 to cut steel with different thicknesses, and at the same time, the adjustment plate 15 is limited and guided by the adjustment holes 14 to ensure the displacement stability of the adjustment plate 15.

[0031] At the same time, to improve the cutting diversity of the cutting wheel 8, the cutting angle of the cutting wheel 8 needs to be adjusted. As Figure 2 and Figure 3As shown, a driven gear 18 is installed on one side of the bottom end of an active plate 13 away from the material table 1. The main gear 19 meshes with the bottom end of the driven gear 18. On one side of the material table 1 corresponding to the main gear 19, a driving motor 20 is installed, and the output shaft of the driving motor 20 is fixed to the main gear 19. By driving the main gear 19 to rotate by the driving motor 20, the main gear 19 drives one of the active plates 13 to rotate through the meshing driven gear 18. The active plate 13 then drives the adjusting plate 15 connected to the first electric push rod 17 to rotate, and thus drives the cutting wheel 8 in the housing 7 to rotate, so as to achieve the effect of adjusting the cutting angle of the cutting wheel 8.

[0032] When using the above structure to cut steel, it is necessary to first transport the steel to the cutting wheel 8 and ensure the stability of the steel. As Figure 1 and Figure 2 shown, a feeding table 24 is installed on the front side of the top end of the material table 1, and a support frame 21 is installed on the top of the feeding table 24. Two symmetrically distributed second electric push rods 22 are installed on the top of the support frame 21. A pressing plate 23 is arranged inside the support frame 21, and the bottom end of the second electric push rod 22 passes through the support frame 21 and is fixed to the top of the pressing plate 23. The steel is sent to the material table 1 through the feeding table 24, and the steel is aligned with the cutting wheel 8. Then, the second electric push rod 22 is driven to drive the pressing plate 23 to move downwards, and the pressing plate 23 contacts the steel, so that the steel can be limited and fixed by the extrusion of the pressing plate 23, thereby ensuring the stability of the steel during cutting. Also, since a feeding table 25 is installed on the rear side of the top end of the material table 1, and support plates 26 are installed at the bottoms of both ends of the feeding table 25 and the feeding table 24, the cut steel can be placed on the feeding table 25.

[0033] Finally: The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
