Description

Technical Field

[0001] This utility model relates to the field of angle steel processing technology, and in particular to a drilling device for steel materials used in power transmission towers. Background Technology

[0002] Angle steel towers are tall structures assembled from angle steel (L-shaped steel bars), widely used in power engineering, telecommunications engineering, and other fields. They are primarily composed of angle steel (L-shaped steel bars), possessing high strength and rigidity. Angle steel towers are assembled from multiple angle steel bars, typically processed by drilling holes. These holes facilitate connection, adjustment, weight reduction, ventilation and drainage, standardized production, and subsequent maintenance, ensuring the stability and durability of the angle steel tower.

[0003] When drilling holes in angle steel, the drilling position needs to be adjusted according to the requirements of the angle steel when the model and size of the angle steel change. Conventional drilling equipment and processing fixtures are difficult to adjust according to the drilling position and specifications of the angle steel, resulting in low drilling efficiency or the need to use processing fixtures of various specifications to drill holes in angle steel of different specifications, which leads to high drilling costs. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a drilling equipment for steel of power transmission towers, so as to solve the problem that the processing tooling is difficult to adapt to the drilling position and specifications of angle steel, resulting in low drilling efficiency of angle steel.

[0007] A limiting rod is set parallel to the upper surface of the processing table, and the top of the support column is fixedly connected to the side wall of the limiting rod.

[0008] Two limiting plates are installed tangentially on the outer wall of the limiting rod. The two limiting plates are symmetrically arranged along the vertical center face of the end face of the limiting rod. The upper surface of the limiting plate is hinged to the side wall of the limiting rod. The drilling machine can be perpendicular to the surface of the limiting plate.

[0010] A vertically movable pressure control, which is located on the upper side of the limiting rod and vertically opposite to the limiting rod.

[0011] The technical principle of the utility model is as follows: when punching is carried out, the pressure control is controlled to move upwards, at this time, the angle steel is placed on the limiting rod; then the pressure control is controlled to move downwards and press on the upper surface of the angle steel, the upper surface of the angle steel is in contact with the lower surface of the elastic pressure control, the pressure control closely adapts to the surface of the angle steel, and the angle steel is stably pre-installed on the limiting rod; then the two ends of the horizontal telescopic assembly are controlled to be elongated, the two ends of the horizontal telescopic assembly drive the two limiting plates to rotate relative to the limiting rod, at this time, the two limiting plates are supported on the lower side wall of the angle steel after being rotated, and the support and fixation of the angle steel are realized; after the positioning and clamping are completed, the angle steel can be drilled by a drilling machine.
