[0025] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0026] See also Figures 1 to 4This embodiment provides an angle steel auxiliary drilling device for an angle steel tower, comprising: a base 1, the base 1 comprising a bottom plate 11 for placing the angle steel, a through hole being provided in the middle of the bottom plate 11, and steel chips generated when drilling the angle steel falling into the hole;

[0027] The clamping mechanism 2 is located above the base 1 and is used to clamp the angle steel placed on the base 1;

[0028] The discharge cover 3 is located below the base 1 and can rotate along the base 1. When the discharge cover 3 is rotated to a horizontal position to block the hole of the base 1, the steel chips are collected. When the discharge cover 3 is rotated to an inclined position to leave the hole of the base 1, the steel chips are discharged.

[0029] The base 1 also includes a number of cross bars 12, protruding bars 13, baffles 14 and a number of grooves 15. The cross bars 12 are all located in the holes of the bottom plate 11. Both ends of the cross bars 12 are fixedly connected to the bottom plate 11. Angle steel is placed on the cross bars 12 for drilling operations. Steel chips fall from the gaps between the cross bars 12 onto the cover plate 31 without affecting the drilling work.

[0030] The baffle 14 is fixed to one end of the upper surface of the base plate 11. A notch is provided in the middle of the inner side of the baffle 14. One end of the angle steel is placed in the notch to limit the movement of the angle steel. The protruding rod 13 is fixed to the outer side of the base plate 11 and is located on the same side as the baffle 14. The groove 15 is located at the other end of the upper surface of the base plate 11, opposite to the baffle 14.

[0031] The clamping mechanism 2 includes a splint 21, a connecting plate 22, a screw 23, a screw nut 24, two guide rods 25, a knob 26 and two connecting blocks 27. The splint 21 is located on the upper surface of the base plate 11 and is arranged opposite to the baffle 14. A notch is provided in the middle part of the inner side of the splint 21, and the other end of the angle steel is placed in the notch to limit the movement of the angle steel. The splint 21 can slide back and forth along the base plate 11. The splint 21 moves toward the baffle 14 to clamp the angle steel, and the splint 21 moves away from the baffle 14 to release the angle steel.

[0032] The screw nut 24 is fixed in the middle of the bottom of the splint 21, and the two connecting blocks 27 are fixed at the bottom of the splint 21 and are located on both sides of the screw nut 24. The screw 23 passes through the screw nut 24 and is threadedly connected to it. The two guide rods 25 are slidably connected to the corresponding connecting blocks 27 respectively. The connecting plate 22 is fixed on the two guide rods 25 and the ends of the screw 23, connecting the two guide rods 25 and the ends of the screw 23. The knob 26 is fixedly connected to one end of the screw 23 and is rotatably connected to the connecting plate 22. Turning the knob 26 drives the screw 23 to rotate, and the screw nut 24 slides along the screw 23, driving the splint 21 to move left and right. The splint 21 moves toward the baffle 14, clamping the angle steel, and the splint 21 moves away from the baffle 14, loosening the angle steel.

[0033] The unloading cover 3 includes a cover plate 31, two brackets 32, side columns 33, a plurality of inclined rods 34, a plurality of recessed holes 35, a support block 36 and a hook 37. The two brackets 32 are fixedly arranged on the lower surface of the base plate 11, and the two ends of the side columns 33 are respectively rotatably arranged on the side surfaces of the corresponding brackets 32. One edge of the cover plate 31 is fixedly connected to the cover plate 31.

[0034] The inclined rods 34 are fixedly arranged on the lower surface of the base plate 11, and the recessed holes 35 are arranged on the side columns 33. When the cover plate 31 rotates, the recessed holes 35 turn to the inclined rods 34, so that the inclined rods 34 are inserted into the recessed holes 35, preventing the cover plate 31 from continuing to rotate, so that the cover plate 31 rotates to a small angle, and the steel chips on the cover plate 31 slide down along one side of the cover plate 31, avoiding the cover plate 31 from rotating to a large angle, and the sliding steel chips are difficult to control and collect.

[0035] The support block 36 is fixedly arranged on the side of the cover plate 31 and is located on the same side as the protruding rod 13. The hook 37 is rotatably arranged on the upper surface of the support block 36. When the hook 37 rotates to hook the protruding rod 13, the cover plate 31 cannot rotate, blocking the hole of the base 1 and collecting steel chips. When the hook 37 rotates to disengage from the protruding rod 13, the cover plate 31 can rotate to discharge the steel chips.

[0036] The screw nut 24 moves backward along the screw rod 23, driving the clamping plate 21 away from the angle steel. As the clamping plate 21 moves forward, the notch of the clamping plate 21 is pressed against the end of the angle steel, pressing the angle steel tightly between the baffle 14 and the clamping plate 21 to prevent the angle steel from being driven during drilling and reducing the accuracy of drilling. After the drilling is completed, the knob 26 is turned in the opposite direction, the screw rod 23 rotates along the knob 26, and the screw nut 24 moves backward along the screw rod 23, driving the clamping plate 21 away from the angle steel. As the clamping plate 21 moves backward, the baffle 14 and the clamping plate 21 lose their restriction on the angle steel, and the angle steel after drilling is taken out, and the next round of drilling operation can be carried out. When there are too many steel chips accumulated on the cover plate 31, the steel chips need to be cleaned. The hook 37 is pulled up, and the cover plate 31 rotates in the opposite direction around the side column 33 and turns to the bottom plate 11, and the hook 37 is rotated so that the end of the hook 37 is hung on the convex rod 13, and the cover plate 31 cannot rotate, thereby sealing the bottom plate 11 and receiving the steel chips generated during drilling. The steel chips are collected and processed centrally to prevent the steel chips from accumulating and affecting the accuracy of drilling.
