Description

Technical Field

[0001] This utility model relates to the field of mechanical drilling technology, and in particular to a drilling device for the web plate of a steel structure cross column. Background Technology

[0002] A steel cross column is a classic form of steel structure, consisting of two intersecting steel columns, typically in an "H" or "+" shape, hence also known as an "H" column or "+" column. Its characteristics include high load-bearing capacity and rigidity, effectively resisting horizontal loads and seismic forces, making it one of the most commonly used structural forms in the construction and engineering fields.

[0003] When drilling holes in a cross-shaped steel structure, the traditional method is to clamp and position a single piece of steel before drilling. This method is inefficient and cannot simultaneously clamp multiple pieces of steel for drilling. To solve these problems, a hole-making device for the web of a cross-shaped steel structure is needed. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the traditional operation method proposed in the prior art involves clamping and positioning a single steel material before drilling, which results in low processing and drilling efficiency. Therefore, this invention proposes a hole-making device for the web of a steel structure cross column.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A drilling device for the web of a steel cross-shaped column includes a worktable. A fixed plate is fixedly connected to the upper surface of the worktable. A guide rail is fixedly connected to the upper surface of the fixed plate. A push plate is slidably connected to the surface of the fixed plate. Multiple sliders are slidably connected to the surface of the guide rail. The lower surface of the push plate is slidably connected to the upper surface of the fixed plate. A convex shaft is fixedly connected to the surface of each of the multiple sliders. Multiple pairs of oblique holes are formed on the surface of the push plate. The convex shaft is installed inside the oblique holes. Clamping plates are fixedly connected to the surface of each of the multiple sliders. Multiple T-shaped steel plates are placed above the worktable. A synchronous drilling mechanism is installed on the upper surface of the worktable.

[0007] Preferably, the synchronous drilling mechanism includes a motor fixedly connected to the upper surface of the workbench, a protective plate fixedly connected to the upper surface of the workbench, a lead screw fixedly connected to the output end of the motor, and one end of the lead screw being rotatably connected to the inner wall of the protective plate.

[0008] Furthermore, the surface of the lead screw is connected to multiple movable plates, and the lower surface of the movable plates is slidably connected to the upper surface of the worktable.

[0009] Preferably, the surface of the movable plate is rotatably connected to a first synchronous wheel, a second synchronous wheel, and a third synchronous wheel, and a drill bit is fixedly connected to the surface of each of the first synchronous wheel, the second synchronous wheel, and the third synchronous wheel.

[0010] Furthermore, the surface of the movable plate is rotatably connected to multiple tensioning wheels, and the third synchronous wheel is installed between the multiple tensioning wheels. The surfaces of the first synchronous wheel, the second synchronous wheel, and the third synchronous wheel are fitted with the same synchronous belt, and the surfaces of the multiple tensioning wheels are pressed against the surface of the synchronous belt.

[0011] Preferably, a PLC controller and an electric telescopic rod are fixedly connected to the surface of the workbench, and the output end of the electric telescopic rod is fixedly connected to the surface of the push plate.

[0012] The beneficial effects of this utility model are as follows:

[0013] The push plate slides on the surface of the fixed plate, causing a pair of convex shafts to move under the action of a pair of oblique holes, pushing a pair of sliders closer to each other, and driving a pair of clamping plates to clamp the surface of the T-shaped steel plate, keeping the drilling stable. The PLC controller controls the rotation of the first and second synchronous pulleys, and under the action of the synchronous belt, drives the third synchronous pulley to rotate synchronously. Multiple drill bits rotate synchronously. After the moving plate moves close to the T-shaped steel plate, it performs drilling operations on the surface of the T-shaped steel plate, improving processing efficiency.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-4 A steel structure cross-shaped column web drilling device includes a workbench 1, a fixed plate 21 fixedly connected to the upper surface of the workbench 1, a guide rail 7 fixedly connected to the upper surface of the fixed plate 21, a push plate 3 slidably connected to the surface of the fixed plate 21, a plurality of sliders 8 slidably connected to the surface of the guide rail 7, the lower surface of the push plate 3 slidably connected to the upper surface of the fixed plate 21, a convex shaft 10 fixedly connected to the surface of each of the plurality of sliders 8, a plurality of oblique holes 11 formed on the surface of the push plate 3, the convex shaft 10 installed inside the oblique holes 11, a clamping plate 9 fixedly connected to the surface of each of the plurality of sliders 8, a plurality of T-shaped steel plates 17 placed above the workbench 1, and a synchronous drilling mechanism installed on the upper surface of the workbench 1.

[0021] By setting the push plate 3, changing the position of the push plate 3 will drive multiple pairs of inclined holes 11 to move. A pair of inclined holes 11 are in the shape of an octagon. When the push plate 3 moves, it will drive the convex shaft 10 to be subjected to force, causing a pair of sliders 8 to move closer or further away from each other. By setting the clamping plate 9, the T-shaped steel plate 17 can be positioned and clamped. By setting the synchronous drilling mechanism, synchronous drilling operations can be achieved, improving drilling efficiency.

[0022] In this utility model, reference is made to Figure 1 and Figure 4 The synchronous drilling mechanism includes a motor 4 fixedly connected to the upper surface of the workbench 1. A protective plate 5 is fixedly connected to the upper surface of the workbench 1. A lead screw 12 is fixedly connected to the output end of the motor 4. One end of the lead screw 12 is rotatably connected to the inner wall of the protective plate 5.

[0023] By setting motor 4 and starting motor 4, its output end drives lead screw 12 to rotate. By setting lead screw 12, the moving position of moving plate 18 can be adjusted.

[0024] In this utility model, reference is made to Figure 1 The surface of the lead screw 12 is connected to multiple movable plates 18, and the lower surface of the movable plates 18 is slidably connected to the upper surface of the worktable 1.

[0025] By setting up the movable plate 18, the first synchronous wheel 13, the second synchronous wheel 16 and the third synchronous wheel 19 are installed and fixed, so that they move closer to the T-shaped steel plate 17.

[0026] In this utility model, reference is made to Figure 4The surface of the movable plate 18 is rotatably connected to a first synchronous wheel 13, a second synchronous wheel 16, and a third synchronous wheel 19, and a drill bit 20 is fixedly connected to the surface of each of the first synchronous wheel 13, the second synchronous wheel 16, and the third synchronous wheel 19.

[0027] By setting the first synchronous pulley 13, the second synchronous pulley 16 and the third synchronous pulley 19, multiple drill bits 20 are driven to rotate together to drill holes and perform drilling operations.

[0028] In this utility model, reference is made to Figure 4 Multiple tensioning rollers 14 are rotatably connected to the surface of the movable plate 18. A third synchronous roller 19 is installed between the multiple tensioning rollers 14. The same synchronous belt 15 is fitted and tensioned on the surfaces of the first synchronous roller 13, the second synchronous roller 16 and the third synchronous roller 19. The surfaces of the multiple tensioning rollers 14 are pressed against the surface of the synchronous belt 15.

[0029] By setting multiple tensioning pulleys 14, the movement of the synchronous belt 15 drives the third synchronous pulley 19 to rotate synchronously, while maintaining the compression and tension on the synchronous belt 15.

[0030] In this utility model, reference is made to Figure 2 The surface of the workbench 1 is fixedly connected to a PLC controller 6 and an electric telescopic rod 2, and the output end of the electric telescopic rod 2 is fixedly connected to the surface of the push plate 3.

[0031] By setting up a PLC controller 6, the first synchronous wheel 13 and the second synchronous wheel 16 are driven to rotate synchronously by electric control. By setting up an electric telescopic rod 2, its output end drives the push plate 3 to move.

[0032] Working principle: In use, multiple T-shaped steel plates 17 are placed sequentially between a pair of clamping plates 9. The electric telescopic rod 2 is then activated. The output end of the electric telescopic rod 2 drives the push plate 3 to slide on the surface of the fixed plate 21. At this time, a pair of convex shafts 10 move under the action of a pair of oblique holes 11, causing a pair of sliders 8 to move closer to each other. This causes the pair of clamping plates 9 to clamp the surface of the T-shaped steel plates 17 and keep it stable. Then, the operator controls the PLC controller 6 to make the first synchronous wheel 13 and the second synchronous wheel 16 located on the moving plate 18 rotate electrically, driving the synchronous belt 15 to move. Under the action of multiple tensioning wheels 14, the surface of the synchronous belt 15 wraps around the third synchronous wheel 19, thereby driving the third synchronous wheel 19 to rotate. After multiple drill bits 20 rotate synchronously, the motor 4 is activated. The output end of the motor 4 drives the lead screw 12 to rotate, causing the moving plate 18 to move closer to the T-shaped steel plates 17 to perform drilling operations on the surface of the T-shaped steel plates 17, thereby improving processing efficiency.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
