It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.

[0023] As Figures 1 to 5 shown in the embodiment of the steel beam punching device of the present utility model, the steel beam punching device includes a conveying platform 1, a clamping platform 2 and a punching component 3. The clamping direction of the clamping platform 2 is perpendicular to the conveying direction of the conveying platform 1, and the clamping direction is parallel to the horizontal plane; the conveying platform 1 and the clamping platform 2 are arranged at intervals. In Figure 1 there are three conveying platforms 1, and two clamping platforms 2. Of course, other quantity schemes can also be used. The adjacent conveying platform 1 and clamping platform 2 are fixedly connected. The conveying platform 1 drives the steel beam 5 to convey in the conveying direction, and the clamping of the clamping platform 2 is an opposite clamping scheme. The clamping platform 2 centers the whole steel beam 5 to achieve the purpose of fixing and positioning the steel beam 5 and facilitate the punching operation.

[0024] The punching component 3 is fixedly arranged on the conveying platform 1 between two adjacent clamping platforms 2. The drill bit component 4 provided on the punching component 3 can move along the clamping direction and the direction perpendicular to the horizontal plane; the punching component 3 cooperates with the conveying platform 1 and the clamping platform 2 to efficiently complete the punching operation.

[0025] The clamping platform 2 is provided with an opposing clamping assembly 21 and a rolling shutter cover assembly 22. The opposing clamping assembly 21 includes a pair of clamping blocks 211. The pair of clamping blocks 211 can move simultaneously, and the pair of clamping blocks 211 can approach or move away from each other, so that the clamping platform 2 can center the steel beam 5 as a whole. The clamping blocks 211 are slidably arranged in a chute 201 provided on the clamping platform 2. The rolling shutter cover assembly 22 includes a rolling shutter cover 221 and a moving frame 222 that are fixedly connected. The moving frame 222 is sleeved on the clamping blocks 211. Therefore, the moving frame 222 will be synchronously driven when the clamping blocks 211 approach or move away from each other. Therefore, the moving frame 222 will drive the rolling shutter cover 221 to slide. The rolling shutter cover 221 is slidably arranged on the upper side of the chute 201 to cover the chute 201, so that debris or fragments generated during the drilling operation will not enter the chute 201 inside the clamping platform 2.

[0026] In an embodiment of the present application, preferably, a conveyor belt 11 is provided on the conveying platform 1. The conveyor belt 11 has a gap with the conveying platform 1 in its conveying direction. The gap can allow debris or fragments generated during the drilling operation to fall from the platform, preventing the conveyor belt 11 from jamming.

[0027] In an embodiment of the present application, preferably, the top surfaces of the conveying platform 1 and the clamping platform 2 are at the same horizontal height. The conveying height of the top end of the conveyor belt 11 is higher than the horizontal height of the top surface of the conveying platform 1. In this way, the conveyor belt 11 can effectively transport the steel beam.

[0028] In an embodiment of the present application, preferably, the rolling shutter cover assembly 22 further includes a rolling shutter cylinder 223 and a guide groove plate 224. The rolling shutter cylinder 223 is fixedly arranged at both ends of the clamping platform 2 in the clamping direction, and the guide groove plate 224 is fixedly arranged at the central position of the clamping platform 2 in the clamping direction. The guide groove plate 224 is provided with a U-shaped guide groove 2241. One end of the rolling shutter cover 221 is wound in the rolling shutter cylinder 223, and the other end of the rolling shutter cover 221 is slidably arranged in the U-shaped guide groove 2241. In this way, when the rolling shutter cover 221 is driven by the clamping blocks 211 to slide, one end of the rolling shutter cover 221 will be wound into or out of the rolling shutter cylinder 223, and the other end of the rolling shutter cover 221 will slide into or out of the U-shaped guide groove 2241, so that the rolling shutter cover 221 can always cover the chute 201. The guide groove plate 224 and the top surface of the clamping platform 2 are at the same horizontal height, so it will not interfere with the conveyor belt 11 transporting the steel beam.

[0029] In an embodiment of the present application, preferably, the end of the rolling shutter cover 221 is wound on a rotating shaft 2231 in the rolling shutter cylinder 223. A torsion spring is provided on the rotating shaft 2231 so that the rolling shutter cover 221 has a tendency to retract into the rolling shutter cylinder 223. In this way, the rolling shutter cylinder 223 can effectively wind the rolling shutter cover 221.

[0030] In one embodiment of the present application, preferably, the rolling shutter cover plate 221 is slidably disposed in a cover plate groove 202 provided at the top end of the chute 201, and a baffle 2211 is further fixedly provided at the upper end of the cover plate groove 202; the baffle 2211 covers the upper side of the cover plate groove 202, and the two jointly limit the rolling shutter cover plate 221 to slide the rolling shutter cover plate 221 in the chute 201; the top surface of the baffle 2211 and the top surface of the clamping platform 2 are at the same horizontal height, so that it will not interfere with the conveyor belt 11 transporting the steel beam.

[0031] In one embodiment of the present application, preferably, a roller 2111 is further provided in the clamping block 211. The roller 2111 is used to directly contact the steel beam, and the height of the bottom end of the roller 2111 is lower than the horizontal height of the top surface of the clamping platform 2; by providing the roller 2111, when the conveyor belt 11 conveys the steel beam, as long as the conveying force of the conveyor belt 11 is greater than the rolling resistance of the roller 2111, the steel beam can be effectively conveyed on the conveyor belt 11, so there is no need to frequently change the clamping force on the clamping assembly 21.

[0032] In one embodiment of the present application, preferably, the roller 2111 has two sides with different diameters; in this way, when dealing with I-shaped steel beams, when the steel beam is conveyed in an "I" shape by the conveyor belt 11, the short-diameter side of the roller 2111 can be inserted into both ends of the bottom end surface of the steel beam to make the clamping more stable; and when the steel beam is conveyed in an "H" shape by the conveyor belt 11, the long-diameter side of the roller 2111 can also effectively clamp both sides of the steel beam.

[0033] In one embodiment of the present application, preferably, the opposing clamping assembly 21 further includes a lead screw 212 and a dual-axis motor 213. One end of the lead screw 212 is rotatably disposed in the clamping platform 2, and the other end of the lead screw 212 is connected to the output end of the dual-axis motor 213. The two lead screws 212 and the two clamping blocks 211 are symmetrically arranged on both sides of the dual-axis motor 213; a threaded hole provided on the clamping block 211 is threadedly connected to the lead screw 212; in this way, both the dual-axis motor 213 and the lead screw 212 are covered by the rolling shutter cover plate 221 inside the clamping platform 2, and the two clamping blocks 211 can be effectively controlled to move simultaneously to approach or move away from each other.

[0034] In an embodiment of the present application, preferably, the drilling assembly 3 includes a column 31, a hydraulic cylinder 32, a sliding cross beam 33, a drilling lead screw 34, a drill bit slider 35, and a motor 36. There are two columns 31. Two hydraulic cylinders 32 are fixedly arranged at the tops of the two columns 31 respectively. The output end of the hydraulic cylinder 32 faces downward and is fixedly connected to the sliding cross beam 33. The sliding cross beam 33 can slide along the length direction of the column 31. Therefore, the hydraulic cylinder 32 can control the sliding cross beam 33 to slide downward or reset upward. The drilling lead screw 34 is rotatably passed through the sliding cross beam 33. The drilling lead screw 34 is in threaded cooperation with the threaded hole on the drill bit slider 35. When the drilling lead screw 34 rotates, the drill bit slider 35 can slide on the sliding cross beam 33. A chute is provided on the bottom end surface of the sliding cross beam 33. The drill bit slider 35 is slidably arranged in the chute. The motor 36 is fixedly arranged at the end of the sliding cross beam 33. The output end of the motor 36 is connected to the drilling lead screw 34. The drill bit assembly 4 is fixedly arranged on the drill bit slider 35. When the two hydraulic cylinders 32 drive the sliding cross beam 33 to press downward together, the drill bit assembly 4 will be pressed downward synchronously. When the drilling lead screw 34 rotates, it can drive the drill bit assembly 4 to slide along the clamping direction. Therefore, the drill bit assembly 4 can move along the clamping direction and the direction perpendicular to the horizontal plane to complete the drilling process.
