Description

Technical Field

[0001] The utility model relates to the technical field of power iron tower construction, in particular to a drilling tool applied to angle steel of a power iron tower. Background Art

[0002] Angle steel, commonly known as angle iron, is a long steel strip with two sides perpendicular to each other. There are equal-leg angle steel and unequal-leg angle steel. The two sides of equal-leg angle steel are equal in width. Angle steel can be used to form various load-bearing components according to different structural needs, and can also be used as a connector between components. It is widely used in various building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, and warehouse shelves. In the process of building power towers, angle steel plays the role of connecting steel pipes, and the connection area needs to be drilled. Therefore, the upper end of the angle steel used in the construction of power towers needs to be drilled.

[0003] In view of this, Chinese Patent No. CN219170218U proposes a drilling tool for angle steels of power towers. When the utility model processes holes on the two flange surfaces of the angle steel, there is no need to clamp the angle steel for the second time, which ensures the continuity of the angle steel drilling work, improves the drilling efficiency and processing accuracy, and is conducive to improving the efficiency of the later construction of the power tower. However, in the above technical solution, for the angle steel support, if the angle steel needs to be drilled at equal intervals, the staff needs to release the fixation after drilling a hole and then manually adjust the position of the angle steel to drill the next position, and may need to keep the spacing consistent, which increases the workload of the staff. At the same time, the adjustment may not be able to maintain relative accuracy. Therefore, this type of tooling requires an automatically rotating and moving support structure. Utility Model Content

[0027] Furthermore, a second limiting groove 11 is provided on one side of the outer wall of the tooling base 1 , and a lifting module 12 is slidably provided on the inner wall of the second limiting groove 11 .

[0028] A clamping plate 13 is fixedly provided at the top of the lifting module 12, a rubber pad 14 is fixedly provided at one side of the bottom of the clamping plate 13, a hydraulic rod 15 is fixedly provided at the bottom of the inner wall of the second limiting groove 11, and one end of the hydraulic rod 15 is fixedly connected to the bottom of the lifting module 12, and a rubber pad 14 is provided at one side of the bottom of the clamping plate 13, which can directly contact the surface of the angle steel to prevent the angle steel from being worn;

[0031] Working principle: When using the drilling tool for angle steel of power tower in this design, it is first necessary to connect the support bar 7 at the upper end of the device through the rotating shaft 6 on both sides of the inner wall of the support frame 4, so that when the first motor 16 is driven, the support bar 7 can rotate on the support frame 4, and the angle steel is placed on the edge of the support bar 7 so that its inner wall contacts the two outer walls of the support bar 7, and the clamping plate 13 is used to squeeze it on the support bar 7. When drilling with the drilling equipment, the groove 8 plays a buffering role to prevent the drilling shaft from being squeezed and damaged by the support bar 7. After the drilling is completed, the clamping plate 13 is removed, and the second motor 17 is started to make the second motor 17 rotate. The screw rod 3 rotates, thereby causing the support frame 4 to move with the angle steel to adjust the new drilling position, and the rotation angle of the second motor 17 can be controlled, so that the spacing of the support frame 4 can be the same each time it moves, and no manual adjustment is required by individual staff. At the same time, the spacing can be equal, thereby improving the accuracy of the drilling of the device. After the position of the angle steel is adjusted, the hydraulic rod 15 in the second limit groove 11 is started to push the lifting module 12 to rise and fall, and the clamping plate 13 clamps the angle steel. When clamping, the rubber pad 14 contacts the angle steel to prevent wear, and no manual clamping is required during the process of clamping the fixed angle steel, thereby improving the convenience of using the device.
