Description

Technical Field

[0001] This utility model relates to the field of H-beam flange plates, specifically a drilling device for H-beam flange plates. Background Technology

[0002] H-beams with flanges are a type of steel with a cross-sectional shape resembling the letter "H". They are widely used in construction, bridges, and machinery manufacturing. H-beams have parallel and equal widths on both sides, a large cross-sectional area, and good bending and torsional resistance. The main components of an H-beam include the web and flanges, with the flanges being an important part of the H-beam.

[0003] Chinese Patent Publication No. CN216881813U discloses a drilling device for H-shaped steel flanges, including symmetrically arranged clamping members. Both sides of the two clamping members are fixedly connected by crossbars. The opposite sides of the two crossbars are provided with a first groove, and the crossbars are provided with a second groove communicating with the first groove. A translation plate is slidably connected in the first groove, and a sliding screw is provided in the second groove. The screw is fixedly connected to the end face of the translation plate. However, this device still has some shortcomings. Due to the large weight and long length of the steel plate, when placing the steel plate, one end of the steel plate needs to pass through the bottom of the drilling device and extend to the other side of the drilling device, which makes it inconvenient to place the steel plate. Therefore, we propose an H-shaped steel flange drilling device to solve the above problems. Utility Model Content

[0004] To address the existing problems, this utility model provides a drilling device for H-shaped steel flange plates, which can effectively solve the problems mentioned in the background art.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A drilling device for H-beam flanges includes a base plate. Multiple support columns are fixedly connected to the upper surface of the base plate.

[0008] As a further improvement of this utility model: two second sliding grooves are provided on the inner walls of the two moving grooves, and two second sliders are fixedly connected to the bottom surfaces of the two second moving blocks, with each second sliding groove being adapted to a second slider.

[0010] As a further improvement of this utility model: both the front and back of the mounting frame are fixedly connected to a fixing frame, and a fourth electric push rod is installed on the upper surface of both fixing frames.

[0011] As a further embodiment of this utility model: the output ends of the two fourth electric push rods are fixedly connected to push blocks, and the bottom ends of the two push blocks are fixedly connected to pressure plates.

[0013] As a further improvement of this utility model: the bottom surface of the base plate is fixedly connected to multiple support legs, and the bottom end of each support leg is fixedly connected to an anti-slip pad.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This H-shaped steel flange drilling device uses two sets of third electric push rods to push the clamping plate, thereby clamping the steel plate to be drilled on two support frames. With the cooperation of two moving slots, moving blocks, and the second electric push rod, the two support frames and the steel plate can be moved to the bottom of the drilling device, making it easier to place the steel plate. Furthermore, the first drive motor drives the threaded rod to rotate, thereby moving the drilling device to adjust the drilling position. Therefore, this device effectively solves the problem that existing devices require one end of the steel plate to pass through the bottom of the drilling device and extend to the other side, which makes it inconvenient to place the steel plate.
