Technical Field
[0001] This utility model relates to the field of photovoltaic bracket technology, specifically to a U-shaped steel drilling machine. Background Technology
[0002] Photovoltaic brackets are special brackets designed for placing, installing, and fixing solar panels in a solar photovoltaic power generation system. They facilitate the installation of solar photovoltaic panels on building roofs, curtain walls, or the ground. Common materials include aluminum alloy, carbon steel, and stainless steel. Photovoltaic brackets include mounting bases, base plates, frames, etc.
[0003] Currently, when photovoltaic panels are installed on the top of a building using photovoltaic brackets, U-shaped steel is used to build a support frame. To facilitate the fixing of the photovoltaic brackets, a drilling machine is used to drill holes in the U-shaped steel so that bolts can pass through. However, existing U-shaped steel drilling machines do not have a pressing structure, which makes the U-shaped steel prone to displacement during drilling. Therefore, a new type of U-shaped steel drilling machine is proposed. When the electric hydraulic cylinder pushes the punch down to drill holes in the U-shaped steel, a circular mounting plate pushes the layer plate down to press the U-shaped steel down and prevent it from shifting.

The bottom end of the uprights inside the gantry frame is connected to a shelf through a threaded groove. A rubber plate is glued to the bottom of the shelf. A compression spring is sleeved on the outside of the uprights at the top of the gantry frame.
[0007] By adopting the above technical solution, the electric hydraulic cylinder pushes the circular mounting plate downward. As the circular mounting plate moves downward, it punches holes in the U-shaped steel and simultaneously pushes the layer plate downward, pressing down on the U-shaped steel and preventing it from shifting.

[0011] Specifically, a through hole is provided at the top of the layer plate, and the through hole penetrates the rubber plate.
[0012] Specifically, the top of the pole is connected to a limit block via a threaded groove.
[0013] The beneficial effects of this utility model are:
[0014] The present invention describes a U-shaped steel punching machine, in which an electric hydraulic cylinder pushes a circular mounting plate and a punch at its bottom to move downwards.

[0022] 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.
[0023] When the electric hydraulic cylinder pushes the punch downwards to drill holes in the U-shaped steel, the circular mounting plate pushes the shelf downwards to press down the U-shaped steel and prevent it from shifting. Figure 1-4 As shown, the U-shaped steel punching machine of this utility model includes a base 1, a channel groove 11 is provided on the top surface of the base 1, a gantry frame 2 is fixed to the top of the base 1 by bolts, an electric hydraulic cylinder 3 is mounted on the top of the gantry frame 2 by a mounting bracket, the output shaft of the electric hydraulic cylinder 3 located inside the gantry frame 2 is fixed to a circular mounting plate 13 by bolts, and a punch 14 is fixed to the bottom of the circular mounting plate 13 by bolts;
[0024] The top of the gantry frame 2 is provided with a pressing assembly 7. The pressing assembly 7 includes a vertical rod 701 that passes through and is sleeved at both ends of the top of the gantry frame 2. The bottom end of the vertical rod 701 inside the gantry frame 2 is connected to a shelf 702 through a threaded groove. A rubber plate 705 is glued to the bottom of the shelf 702. A compression spring 704 is sleeved on the outer side of the vertical rod 701 at the top of the gantry frame 2.
[0025] In use, the electric hydraulic cylinder 3 pushes the circular mounting plate 13 downward. As the circular mounting plate 13 moves downward, it punches holes in the U-shaped steel through the punch 14, while simultaneously pushing the layer plate 702 downward, so that it presses down on the U-shaped steel to prevent it from shifting.
[0026] For example, such as Figure 1 , Figure 2 As shown, the present invention also includes a first roller 4 rotatably connected to both ends of the bottom of the channel groove 11 via bearings, a second roller 5 rotatably connected to the bottom of the channel groove 11 on one side of the first roller 4 via bearings, and a servo motor 6 mounted on one side of the base 1 via a mounting bracket.
[0027] In use, the servo motor 6 drives the first roller 4 to rotate and push the U-shaped steel in the channel groove 11 to move, and the second roller 5 is used to assist the movement of the U-shaped steel.
[0028] For example, as shown in the figure Figure 1 , Figure 2 As shown, the present invention also includes a second synchronous wheel 9 fixed to one side of the output shaft of the servo motor 6 by a flat key, a first synchronous wheel 8 fixedly sleeved on one end of the first roller 4 located outside the base 1 by a flat key, and a synchronous belt 10 sleeved on the outside of the first synchronous wheel 8 and the second synchronous wheel 9.
[0029] In use, the servo motor 6 drives the first roller 4 to rotate through the second synchronous pulley 9, the first synchronous pulley 8 and the synchronous belt 10.
[0030] For example, such as Figure 2 As shown, the present invention also includes auxiliary rollers 12 that are equidistantly mounted on both sides of the inside of the channel groove 11 via mounting brackets.
[0031] When in use, the auxiliary roller 12 is provided to prevent the U-shaped steel from rubbing against its inner side when it moves in the channel groove 11.
[0032] For example, such as Figure 4 As shown, the present invention also includes a through hole 703 on the top of the layer 702, the through hole 703 penetrating the rubber plate 705.
[0033] When in use, the through hole 703 facilitates the penetration of the punch 14, and the rubber plate 705 serves as an anti-slip measure.
[0034] For example, such as Figure 4 As shown, the present invention also includes a limit block 706 connected to the top of the upright 701 via a threaded groove.
[0035] When in use, the limit block 706 can prevent the upright 701 from falling off the gantry 2 and can also prevent the compression spring 704 from falling off the outside of the upright 701.
[0036] When using this utility model, the operator connects the device to an external power source using a power cord, places one end of the U-shaped steel to be drilled into the channel groove 11, and pushes it into the gantry frame 2.
[0037] Open the electric hydraulic cylinder 3 to push the circular mounting plate 13 and the punch 14 at its bottom to move down. The punch 14 moves down to punch a hole in the U-shaped steel. The diameter of the circular mounting plate 13 is larger than the through hole 703. While not affecting the downward movement of the punch 14, the layer plate 702 can be pushed down.
[0038] The circular mounting plate 13 moves down, pushing the shelf 702 down so that it presses against the U-shaped steel, which can hold the U-shaped steel in place and prevent it from shifting when drilling. When the circular mounting plate 13 moves up, the compression spring 704 pushes the upright 701 and the shelf 702 up and reset through the limit block 706.
[0039] When the operator turns on the servo motor 6, the first roller 4 is driven to rotate through the second synchronous wheel 9, the first synchronous wheel 8 and the synchronous belt 10. This can push the U-shaped steel in the channel groove 11 to move, making it convenient for the operator to drill holes in the U-shaped steel at equal intervals.
