[0002] Currently, with the increasing scale of chemical plants, the use of steel structures is becoming more optimized, and the scale of steel structures is also becoming larger. From the original on-site prefabrication of raw materials to the delivery of prefabricated products, and from single-piece installation to the installation of sections and frames, the characteristics and requirements of short construction periods for steel structure projects are becoming more and more obvious. In the past, a steel structure frame on the market was sufficient to meet the height of first- or second-level columns, but now it is often necessary to meet the height of third- or fourth-level columns. Therefore, H-beam steel columns need to be equipped with connection holes for connection.

[0003] In the existing technology, when drilling holes for H-beams at the construction site, workers usually use hand-held electric drills to drill according to the pre-marked hole positions. However, the accuracy of the hole positions is difficult to guarantee during operation, and deviations are prone to occur, making it difficult to meet the strict requirements of the project for hole position accuracy. Summary of the Invention

[0004] To address the shortcomings of existing technology and solve the problem that when drilling H-beams on construction sites, workers typically use handheld electric drills to drill according to pre-marked hole positions, but the accuracy of the hole positions is difficult to guarantee during operation, and deviations are prone to occur, making it difficult to meet the strict requirements of the project for hole position accuracy.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figures 1 to 4 As shown, an H-beam steel connection hole opening device according to an embodiment of the present invention includes a support plate 1 and an opening mechanism on the support plate 1. The opening mechanism includes: a fixing component, including a pair of concave plates 2 fixedly connected to both sides of the support plate 1, a pair of sliding rods 3 slidably connected to the concave plates 2 through a pair of sliding holes, a concave frame 4 fixedly connected to the bottom of the pair of sliding rods 3, a clamping plate 5 fixedly connected to one end of the pair of sliding rods 3, a rubber pad 6 provided on the side wall of the clamping plate 5, and an adjusting component for moving the pair of concave frames 4 on the support plate 1; and a drilling component, which is provided on the support plate 1 for opening holes.

[0022] During operation, the position of a pair of concave frames 4 is adjusted simultaneously by the set adjustment components, and the center of the H-beam is clamped by a pair of clamping plates 5, thereby fixing the position of the support plate 1. Stable drilling can then be performed by the drilling components. This solves the problem in the existing technology where, when drilling H-beams on the construction site, workers usually hold an electric drill 16 and drill according to the pre-marked hole positions. However, the hole position accuracy is difficult to guarantee during operation, and deviations are prone to occur, making it difficult to meet the strict requirements of the project for hole position accuracy.

[0023] The adjustment assembly includes a fixed plate 7 fixed to the top of the support plate 1 by a pair of fixed rods, a motor 8 fixed to the bottom of the fixed plate 7, a drive rod 9 provided at the output end of the motor 8, and a first connecting rod 10 fixed to the bottom of the drive rod 9.

[0024] The top of both ends of the first connecting rod 10 are rotatably connected to the second connecting rod 11 via the first rotating shaft. The end of the second connecting rod 11 away from the first connecting rod 10 is rotatably connected to the top of the concave frame 4 via the second rotating shaft.

[0025] During operation, the motor 8 is started, and the output end of the motor 8 drives the drive rod 9 to rotate. The drive rod 9 drives a pair of concave frames 4 to move through the first connecting rod 10, the first rotating shaft, the second connecting rod 11, and the second rotating shaft, thereby causing the clamping plate 5 to move closer to the H-beam. The rubber pad 6 on the side wall of the clamping plate 5 contacts and clamps the H-beam, thus fixing the position of the support plate 1, which allows for drilling at the fixed position.

[0026] The drilling assembly includes a support frame 12 fixed to the top of the support plate 1. Rectangular holes 13 are provided on both sides of the support frame 12. Sliding blocks 14 are slidably connected in the rectangular holes 13. A rectangular plate 15 is fixed between a pair of sliding blocks 14. An electric drill 16 is fixed to the rectangular plate 15 through a pair of fixing holes. An electric push rod 17 is fixed to the top of the support plate 1. The telescopic end of the electric push rod 17 is fixed to the bottom of the rectangular plate 15. A pair of through holes 18 are provided on the support plate 1.

[0027] During operation, after the support plate 1 is fixed in position, the electric actuator 17 is activated. The telescopic end of the electric actuator 17 pushes the rectangular plate 15 downward along the rectangular holes 13 on both sides of the support frame 12. The electric drill 16 on the rectangular plate 15 moves downward accordingly until the drill bit of the electric drill 16 passes through the through hole 18 on the support plate 1 and contacts the H-beam. At this time, the electric drill 16 is activated to drill holes in the H-beam, creating connection holes.

[0028] A rectangular groove 19 is provided at the bottom of the support plate 1, and a set of circular rollers 20 are rotatably connected between the opposite side walls of the rectangular groove 19 via a set of third rotating shafts.

[0029] During operation, the circular roller 20 at the bottom of the support plate 1 allows the staff to easily move the support plate 1 and make it convenient for the staff to drill holes.

[0030] A support rod 21 is fixedly connected to the side wall of the sliding rod 3, and a collection box 22 is fixedly connected to the side wall of the support rod 21.

[0031] During operation, the support rod 21 moves the clamping plate 5 and simultaneously moves the collection box 22, placing the collection box 22 below the electric drill 16 to collect waste chips, preventing them from scattering and facilitating subsequent cleaning and collection, thus maintaining a clean working environment.

[0032] Working principle: The position of a pair of concave frames 4 is adjusted simultaneously by the set adjustment components, and the center of the H-beam is clamped by a pair of clamping plates 5, thereby fixing the position of the support plate 1. Stable drilling can then be performed by the drilling components. This solves the problem in the existing technology where workers usually hold an electric drill 16 and drill according to the pre-marked hole positions when drilling H-beams on the construction site. However, the hole position accuracy is difficult to guarantee during operation, and deviations are prone to occur, making it difficult to meet the strict requirements of the project for hole position accuracy.

[0033] By starting the motor 8, the output end of the motor 8 drives the drive rod 9 to rotate. The drive rod 9 drives a pair of concave frames 4 to move through the first connecting rod 10, the first rotating shaft, the second connecting rod 11, and the second rotating shaft, thereby causing the clamping plate 5 to move closer to the H-beam. The rubber pad 6 on the side wall of the clamping plate 5 contacts and clamps the H-beam, thus fixing the position of the support plate 1, which allows for opening holes in the fixed position.

[0034] After the support plate 1 is fixed in position, the electric actuator 17 is activated. The telescopic end of the electric actuator 17 pushes the rectangular plate 15 downward along the rectangular holes 13 on both sides of the support frame 12. The electric drill 16 on the rectangular plate 15 moves downward accordingly until the drill bit of the electric drill 16 passes through the through hole 18 on the support plate 1 and contacts the H-beam. At this time, the electric drill 16 is activated to drill holes in the H-beam to create connecting holes.

[0035] The support plate 1 is equipped with a circular roller 20 at its bottom, which allows the staff to move the support plate 1 and make it easier for them to drill holes.

[0036] The support rod 21 allows the collection box 22 to move simultaneously with the clamping plate 5, positioning the collection box 22 below the electric drill 16 to collect waste chips, preventing them from scattering and facilitating subsequent cleaning and collection, thus maintaining a clean working environment.
