Description

Technical Field

[0001] This solution belongs to the field of laser cutting equipment, specifically involving a steel structure laser cutting device with protective functions. Background Technology

[0002] Steel structures are mainly composed of components made of materials such as shaped steel and steel plates. Depending on the needs of different sites, steel structures are usually processed. Using laser cutting equipment for steel plate processing has the advantages of fast processing and high degree of automation.

[0003] A search revealed a utility model patent with authorization announcement number CN218225145U, which discloses a laser cutting device for steel structure processing. The device includes a support column, a U-shaped plate welded to the top surface of the support column, top plates welded to both sides of the U-shaped plate, a main roller and a driven roller rotatably arranged between the two inner sides of the U-shaped plate, a conveyor belt installed on the outer surface of the main roller and the driven roller, and a driven pulley installed at one end of the main roller. A fixed plate is welded to the top surface of one of the top plates, and a baffle is welded to the top surface of the other top plate. A slide rail is fixedly connected to the side of the fixed plate, and an L-shaped plate is slidably connected to the outer surface of the slide rail.

[0004] However, cutting steel structures generates a large amount of smoke, dust, and hot debris. Due to the lack of protection, this not only pollutes the environment but may also damage equipment or endanger the health of operators. Utility Model Content

[0005] The purpose of this solution is to provide a steel structure laser cutting device with protective functions to solve the problem that existing laser cutting devices lack protection against smoke and splashes.

[0006] To achieve the above objectives, this solution provides a steel structure laser cutting device with protective functions, including a support roller frame. A water tank is fixedly connected to the bottom of the support roller frame. Two slide rails are fixedly connected to the upper end of the support roller frame. A gantry frame is fixedly connected between the two slide rails. A laser cutting machine is mounted on the gantry frame. A fixed base is fixedly connected to the outside of the laser cutting machine. A mounting plate is in contact with the bottom of the fixed base. A mounting locking mechanism is provided between the mounting plate and the fixed base. A protective cover is fixedly connected to the bottom of the mounting plate. A connecting pipe is fixedly connected inside the fixed base and penetrates through the fixed base. An air pump is fixedly installed on the outside of the water tank. The output end of the air pump is connected to the water tank. A connecting hose is fixedly connected between the input end of the air pump and the connecting pipe.

[0007] The principle of this solution is as follows: When the laser cutting machine is laser cutting the plate on the support roller frame, it will generate splatter and fumes. First, the splatter will be protected by a protective cover to prevent further splattering. The fumes will be drawn into the water tank by the air pump, connecting hose and connecting pipe to further neutralize the high temperature fumes and improve the safety of the working environment. In addition, if the protective cover needs to be replaced later, simply pull the connecting piece horizontally by the pull ring. The connecting piece will pull the locking pin, which will separate the locking pin from the positioning block and release the restriction on the mounting plate. Then the mounting plate can be removed together for replacement.

[0008] The technical advantages of this solution are as follows: By setting up an installation plate, protective cover, and center-of-gravity ring on the laser cutting machine, and then installing an air pump at the water tank, the input end of the air pump is equipped with a connecting pipe with a connecting hose. After passing through the fixed seat on the laser cutting machine, the connecting pipe enters the inside of the protective cover. In this way, smoke and splashes can be stably adsorbed during the laser cutting process, and at the same time, the smoke is drawn into the water tank to further neutralize the high-temperature smoke and improve the safety of the working environment.

[0009] An installation locking mechanism is set between the fixed base and the mounting plate. The installation locking mechanism uses a spring-driven locking pin that cooperates with the positioning block. The protective cover can be removed or fixed in one step by pulling the ring, without tools, which greatly simplifies the replacement or cleaning process.

[0010] Furthermore, a center-of-gravity ring is connected to the bottom of the protective cover, and the center-of-gravity ring is circular. This center-of-gravity ring ensures that the center of gravity of the protective cover always faces the same direction.

[0011] Furthermore, a filter plate is inserted inside the water tank, and a baffle is fixedly connected to the filter plate, with the baffle abutting against the outer wall of the water tank. The filter plate effectively filters the welding slag generated during cutting, preventing excessive slag from entering the water tank.

[0012] Furthermore, a handle is welded onto the stop block, and the handle is made of stainless steel. The handle facilitates pushing and pulling the filter plate.

[0013] Furthermore, the installation locking mechanism includes a positioning block fixedly connected to the upper end of the mounting plate. The positioning block is inserted into a fixed base. A retaining ring is fixedly connected to the side of the fixed base. A locking pin is slidably connected inside the retaining ring. The locking pin passes through the retaining ring and is slidably connected to the fixed base. One end of the locking pin is fixedly connected to the positioning block, and the other end is fixedly connected to a connecting piece. A pull ring is welded onto the connecting piece, and a spring is sleeved on the outside of the locking pin. This installation locking mechanism allows for quick assembly and disassembly of the mounting plate, protective cover, and center of gravity ring.

[0014] Furthermore, one end of the spring is fixedly connected to the retaining ring, and the other end of the spring is fixedly connected to the connecting piece. By using the spring, the elastic force can be applied to the locking pin through the connecting piece.

[0015] Furthermore, a protective sleeve is fixedly connected between the retaining ring and the connecting piece, and the protective sleeve is located on the outside of the spring. The protective sleeve provides protection for the spring. Attached Figure Description

Detailed Implementation

[0019] The basic implementation examples are as follows: Figures 1-4 As shown: A steel structure laser cutting device with protective function includes a support roller frame 2, a water tank 1 fixedly connected to the bottom of the support roller frame 2, two slide rails 3 fixedly connected to the upper end of the support roller frame 2, a gantry frame 4 fixedly connected between the two slide rails 3, a laser cutter 5 mounted on the gantry frame 4, a fixed base 6 fixedly connected to the outside of the laser cutter 5, a mounting plate 8 contacting the bottom of the fixed base 6, a protective cover 9 fixedly connected to the bottom of the mounting plate 8, and a center-of-gravity ring 10 connected to the bottom of the protective cover 9, the center-of-gravity ring 10 being circular. The center-of-gravity ring 10 ensures that the center of gravity of the protective cover 9 always faces the same direction. A connecting pipe 11 is fixedly connected inside the fixed base 6, and the connecting pipe 11 penetrates the fixed base 6. An air pump 12 is fixedly installed on the outside of the water tank 1, the output end of the air pump 12 is connected to the water tank 1, and a connecting hose 16 is fixedly connected between the input end of the air pump 12 and the connecting pipe 11.

[0020] like Figure 1 , 2 , Figure 3 As shown, a filter plate 13 is inserted inside the water tank 1, and a stop block 14 is fixedly connected to the filter plate 13, with the stop block 14 abutting against the outer wall of the water tank 1. The filter plate 13 filters the welding slag generated during cutting, preventing excessive welding slag from entering the water tank 1. A handle 15, made of stainless steel, is welded to the stop block 14. The handle 15 facilitates pushing and pulling the filter plate 13.

[0021] like Figure 3 , 4 As shown, a mounting locking mechanism 7 is provided between the mounting plate 8 and the fixed base 6. This mechanism allows for quick assembly and disassembly of the mounting plate 8, protective cover 9, and center-of-gravity ring 10. The mounting locking mechanism 7 includes a positioning block 71 fixedly connected to the upper end of the mounting plate 8. The positioning block 71 is inserted into the fixed base 6. A retaining ring 72 is fixedly connected to the side of the fixed base 6. A locking pin 73 is slidably connected inside the retaining ring 72, penetrating the retaining ring 72. The locking pin 73 is slidably connected to the fixed base 6. One end of the locking pin 73 is fixedly connected to the positioning block 71, and the other end is fixedly connected to a connecting piece 74. A pull ring 75 is welded to the connecting piece 74. A spring 76 is sleeved on the outside of the locking pin 73. One end of the spring 76 is fixedly connected to the retaining ring 72, and the other end is fixedly connected to the connecting piece 74. The spring 76 allows the elastic force to be applied to the locking pin 73 through the connecting piece 74. A protective sleeve 77 is fixedly connected between the retaining ring 72 and the connecting piece 74, and the protective sleeve 77 is located on the outside of the spring 76. The protective sleeve 77 provides protection for the spring 76.

[0022] The specific implementation process of this utility model is as follows: When the laser cutting machine 5 is laser cutting the plate on the support roller frame 2, it will generate splatter and smoke. First, the splatter will be protected by the protective cover 9 to prevent further splattering. The smoke will be drawn into the water tank 1 by the air pump 12, the connecting hose 16 and the connecting pipe 11 to further neutralize the high temperature smoke and improve the safety of the working environment. In addition, if the protective cover 9 needs to be replaced later, simply pull the connecting piece 74 horizontally by the pull ring 75. The connecting piece 74 pulls the locking pin 73, so that the locking pin 73 is separated from the positioning block 71, which will release the restriction on the mounting plate 8. Then the mounting plate 8 can be removed together for replacement.

[0023] This solution involves installing a mounting plate 8, a protective cover 9, and a center-of-gravity ring 10 on the laser cutting machine 5, and then installing an air pump 12 at the water tank 1. The input end of the air pump 12 is equipped with a connecting pipe 11 with a connecting hose 16. The connecting pipe 11 passes through the fixing seat 6 on the laser cutting machine 5 and enters the inside of the protective cover 9. In this way, smoke and splashes can be stably adsorbed during the laser cutting process, and at the same time, the smoke is drawn into the water tank 1 to further neutralize the high-temperature smoke and improve the safety of the working environment.

[0024] An installation locking mechanism 7 is set between the fixed base 6 and the mounting plate 8. The installation locking mechanism 7 uses a locking pin 73 driven by a spring 76 to cooperate with the positioning block 71. The protective cover 9 can be disassembled or fixed in one step by pulling the ring 75 without tools, which greatly simplifies the replacement or cleaning process.
