[0037] Reference Figure 1 As shown, the present application provides a technical solution: a drilling device for a steel structure, comprising a basic frame 1 for supporting a side panel 2, the side panel 2 is arranged on the top of the basic frame 1, and a conveyor belt 5 is installed inside the side panel 2, the conveyor belt 5 is sleeved on the outside of two rotating rollers 24, and the conveyor belt 5 is driven by the rotation of the rotating rollers 24 to transport the steel structure.

[0038] like Figure 3 As shown, the front end of the left rotating roller 24 is coaxially fixed with the first worm gear 7, and the lower end of the first worm gear 7 is connected to the first worm 6, the right end of the first worm 6 is fixedly connected to the motor, and the first worm 6 is intermittently meshed with the first worm gear 7;

[0039] like Figure 1 As shown, the steel structure to be drilled is placed on the conveyor belt 5 from the left, and then the motor at the right end of the first worm 6 is turned on to control its uniform rotation, and the first worm wheel 7 and the first worm 6 are intermittently meshed to realize the intermittent transmission of the conveyor belt 5. When the steel structure is transported to the bottom of the drilling machine 21, the first worm wheel 7 and the first worm 6 stop meshing, the transmission belt 5 stops, and the steel structure remains stationary.

[0040] like Figure 2 As shown, the rear end of the screw rod 8 is fixedly connected to the motor, and the screw rod 8 is installed between the moving block 12 on the left and the moving block 12 on the right, and the outer side of the screw rod 8 is rotatably connected with a connecting block 9, and the moving directions of the two connecting blocks 9 are opposite.

[0041] During use, the motor controls the screw rod 8 to rotate. At this time, the connecting block 9 drives the clamping plate 10 to move toward the direction of the conveyor belt 5. The limit rod 11 limits the moving direction of the connecting block 9 and the clamping plate 10. The upper end of the clamping plate 10 stably clamps the steel structure material, and the screw rod 8 stops rotating. Then the first telescopic rod 3 starts to control the moving block 12 to move upward. The clamping plate 10 drives the steel structure material to move upward and stays stably in the air, ensuring that the steel structure remains stationary during subsequent drilling, avoiding displacement of the steel structure and causing waste of raw materials.

[0042] The support plate 13 is arranged above the conveyor belt 5, and a cavity is opened inside the support plate 13. The upper end of the support plate 13 is fixedly connected to the end of the extension rod of the second telescopic rod 4, and the second telescopic rod 4 is fixedly installed at the lower end of the tooth plate 14. Figure 4 As shown, the first limit blocks 15 are fixedly installed on both the front and rear sides of the tooth plate 14, and the first limit blocks 15 are slidably connected to the grooves opened on the inner side of the side plate 2, and the upper end of the tooth plate 14 is fixedly installed with saw teeth at equal intervals, and the tooth plate 14 is meshed with the gear 16 for transmission, and the rear end of the gear 16 is fixedly connected to the motor;

[0043] The gear 16 rotates and meshes with the toothed plate 14, controlling the toothed plate 14 to drive the second telescopic rod 4 and the support plate 13 to move to the right, and the first limit block 15 slides on the inner side of the side plate 2 to ensure the stability of the movement of the toothed plate 14.

At this time, the drill bit at the bottom of the drilling machine 21 rotates at a high speed, and the second worm 17 controls the second worm wheel 18 and the threaded rod 19 to rotate, so that the second limit block 20 drives the drilling machine 21 downward in the vertical direction to drill holes in the steel structure, thereby preventing the movement trajectory of the drilling machine 21 from deviating and improving the accuracy of drilling;

[0046] The waste chips generated during drilling are sucked into the interior of the support plate 13, and then enter the collection box 22. After the drilling is completed, the support plate 13 moves left to the starting position, the extension rod of the first telescopic rod 3 retracts and the screw 8 reverses, and the steel structure is placed on the surface of the conveyor belt 5. Then the first worm gear 6 and the first worm 7 re-engage to control the conveyor belt 5 to transport the steel structure to the right. The chip collecting bucket 23 absorbs the waste chips remaining on the conveyor belt 5 into the collection box 22 to avoid pollution of the working environment and prevent it from affecting the processing and collection of the steel structure.

[0047] Compared with the prior art, the technical solution of the present application has the following beneficial effects: the steel structure is stably clamped during drilling to prevent it from being displaced due to the impact of the drill bit, and the drill bit is ensured to move in the vertical direction to prevent the drill bit from deviating, and waste chips are adsorbed and collected during drilling for unified treatment, which reduces the difficulty of cleaning and avoids affecting the continuous drilling work;

[0048] 1. A first worm wheel and a first worm are provided. The first worm wheel is continuously rotated so that the first worm and the first worm wheel are intermittently meshed.

[0049] 2. A clamping plate and a second limit block are provided. The screw rod rotates to drive the connecting blocks to move toward each other. The steel structure is stably clamped under the drilling machine by the clamping plate. Then the drilling machine moves downward through the rotation connection between the threaded rod and the second limit block, preventing the drilling machine from deviating from the vertical direction when moving downward, improving the accuracy of drilling and the quality standard of the finished product;

[0050] 3. A pallet, a collection box and a chip collecting bucket are provided. The waste chips generated when drilling the steel structure placed on the upper end of the pallet enter the interior of the pallet.
