Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, in particular to steel plate laser cutting equipment for switchgear. Background Art

[0002] The thickness of high-voltage switchgear cabinets is a crucial parameter in their design and manufacturing, directly impacting operational safety and service life. The thickness of the cabinets must be determined based on a variety of factors, including mechanical strength, insulation performance, heat dissipation requirements, and the operating environment. Thickness requirements vary across voltage levels and application scenarios.

[0003] National standards don't have a single, rigid requirement for high-voltage switchgear cabinet thickness; instead, they prioritize overall equipment performance. For example, GB 3906, "3.6kV to 40.5kV AC Metal-Enclosed Switchgear and Controlgear," emphasizes that the equipment must possess sufficient mechanical strength to withstand the mechanical stresses of normal transportation, installation, and operation. In practice, cabinet steel plate thickness is typically based on industry practice. For 10kV voltage ratings, the main material thickness of cabinets is typically in the 2.0-3.0mm range, while a 3.0-4.0mm thickness is recommended for 35kV voltage ratings. In certain special environments, such as chemical plants where corrosive gases are present, designers may require an increased thickness margin or the use of stainless steel.

[0004] The industry standard DL / T 404, "3.6kV-40.5kV AC Metal-Enclosed Switchgear," explicitly requires that the cabinet's protection level meet IP4X, indirectly influencing thickness selection. A substation project demonstrated that a cabinet constructed of 2.5mm cold-rolled steel sheet developed rust and perforation after three years of use in a coastal salt spray environment. During a subsequent retrofit, the cabinet was replaced with 3.0mm galvanized steel sheet and coated with an anti-rust coating. Equipment manufacturers typically specify cabinet material and thickness parameters in their technical specifications.

[0005] The cabinet door panels, side panels and top covers of the switchgear are all made of stainless steel plates, which are processed by laser cutting machines in the existing technology. During the laser cutting process, metal liquid will be generated on the cutting line of the stainless steel plate, and the metal liquid will flow to the laser cutting machine for deposition. If the laser cutting machine is not cleaned or replaced for a long time, the stainless steel plate will stick to the laser cutting machine during cutting, and the surface of the laser cutting machine will also be uneven. The stainless steel plate placed on the laser cutting machine will also become uneven, resulting in a decrease in the processing accuracy of the stainless steel plate. Summary of the Invention

The sliding drive 16 is fixed to the laser bed frame 1. The output shaft of the laser bed frame 1 is provided with a transmission screw. The transmission screw is threadedly engaged with the sliding seat 14. Both ends of the transmission screw are rotatably mounted on the laser bed frame 1. The function of the rotary drive member 18 is to drive the transmission adjustment component to work, and the transmission adjustment component drives the friction wheel 12 to work. There are two friction wheels 12, and the two friction wheels 12 process both sides of a serrated plate 5 at the same time.

[0026] In some embodiments, the transmission adjustment component includes a fixed gear 19, a movable gear 20, an arc-shaped plate 21, a loading seat 22, a connecting sleeve 23 and a tightening spring 24. The loading seat 22 is fixedly connected to the lifting seat 15. A gear groove is provided on the upper surface of the loading seat 22. Two fixed gears 19 and two movable gears 20 are provided in the gear groove. The two fixed gears 19 are meshed with each other. The two fixed gears 19 are respectively meshed with the two movable gears 20, and the two movable gears 20 do not contact each other. Two adjustment grooves are provided on the loading seat 22. The two adjustment grooves are each provided with an arc-shaped plate 21 that cooperates with the adjustment groove. The movable gear 20 is rotatably set on the arc-shaped plate 21.

The two fixed gears 19 respectively drive the two movable gears 20 to rotate. The two movable gears 20 respectively drive the two friction wheels 12 to rotate through the two connecting sleeves 23, and the friction wheels 12 perform the cleaning work. The two fixed gears 19 are identical gears. A rotating shaft is coaxially fixed on the fixed gear 19 and the movable gear 20. The connecting sleeve 23 is fixed to the end of the rotating shaft.

[0028] In some embodiments, the cross-sections of the main traction wheel 2 and the auxiliary traction wheel 3 are both regular polygons, and anti-slip protrusions 30 are fixedly provided on the outer walls of the main traction wheel 2 and the auxiliary traction wheel 3. The regular polygonal cross-sections of the main traction wheel 2 and the auxiliary traction wheel 3 can better drive the sawtooth seat 6 to move, prevent the sawtooth seat 6 from sliding on the main traction wheel 2 and the auxiliary traction wheel 3, and prevent the sawtooth seats 6 on both sides of the laser bed frame 1 from moving asynchronously. The anti-slip protrusions 30 are provided to prevent the sawtooth seat 6 from falling off the sides of the main traction wheel 2 or the auxiliary traction wheel 3.

[0029] In some embodiments, the auxiliary traction wheel 3 is rotatably mounted on one end of a movable rod 31, the other end of the movable rod 31 is mounted in one end of a fixed sleeve 32, the other end of the fixed sleeve 32 is fixedly mounted on the laser bed frame 1, a spherical groove is provided on the end of the movable rod 31, the spherical groove is engaged with one end of a support rod 33, the middle portion of the support rod 33 is threadedly engaged with an adjustment plate 34, the adjustment plate 34 is fixedly mounted on the end of the fixed sleeve 32, a sliding hole is provided on the end of the support rod 33, and a shifting rod 35 is provided in the sliding hole.

The molten metal on the serrated plate 5 will adhere to the serrated plate 5 after solidification. Dust is generated during the removal process using the friction wheel 12. Dust is harmful to the human body, so it is necessary to remove the dust during the removal process. The waste suction port 37 is an inlet for sucking up dust. The other end of the waste suction port 37 is connected to a dust collection device in the prior art, which can effectively remove dust generated during the operation. During the cleaning process, larger metals will not be sucked away by the dust collection equipment, but will enter the waste conveyor belt 39 from the waste discharge port 38 under the action of gravity. The waste conveyor belt 39 can carry the metal particles. In order to prevent the metal particles from adhering to the waste conveyor belt 39, a stripper plate 41 is used to remove the metal particles on the waste conveyor belt 39. The middle diameter of the two transmission wheels 40 is small and the diameters at both ends are large. A drive motor is provided on the laser bed 1, and the drive motor drives one of the transmission wheels 40 to rotate.

[0031] In some embodiments, a horizontal partition 42 is provided in the middle of the laser bed frame 1. The length of the horizontal partition 42 is greater than the travel distance of the laser cutting head 26. The molten metal produced during the cutting process of the laser cutting head 26 will flow down. To prevent the serrated plate 5 on the lower side of the laser bed frame 1 from being contaminated by the molten metal, the horizontal partition 42 is used to separate it. After the stainless steel plate is cut, some of the molten metal can be blocked by the horizontal partition 42. The horizontal partition 42 is detachably connected to the laser bed frame 1. When the molten metal on the horizontal partition 42 solidifies to a sufficient amount, the horizontal partition 42 can be replaced.
