Abstract

The present invention discloses a cutting device for building steel structures with a synchronous dust removal function, and the present invention relates to the technical field of cutting equipment. During the cutting and dust removal process, an air pump is used to pump the smoke at the cutting position to prevent the smoke from spreading. However, during the air extraction process, particles in the smoke easily clog the pipe, resulting in a reduced dust removal effect. Through the conical shape of the conical cylinder, the filter cylinder is matched during filtration, so that the gap gradually increases from bottom to top, and the air flow rate during filtration is increased, so that the blocked smoke particles continue to be driven upward by the air, so that the blocked smoke particles cooperate with the arc surface of the arc disk under the drive of the air, and the smoke particles are introduced into the gap between the conical cylinder and the air guide cylinder for collection. During cutting, the smoke is removed synchronously, and the smoke particles are blocked and collected at the same time, so as to avoid clogging the gas circulation pipe during the dust removal process, resulting in a reduced dust removal effect.

Description

Technical Field

[0001] The invention relates to the technical field of cutting equipment, in particular to a cutting equipment for building steel structures with a synchronous dust removal function. Background Art

[0002] Building steel structure refers to a structural system made of steel plates and steel sections connected by welding, bolting, or riveting. It is mainly composed of steel sections and steel plates. These steels are processed into various components, including beams, columns, trusses, and grids. For example, in high-rise buildings, steel columns bear the vertical load, and steel beams transfer the floor load to the steel columns. The cutting equipment used for building steel structures mainly uses flame cutting. Flame cutting uses a high-temperature flame generated by the combustion of a mixture of gas and oxygen to heat the steel surface to the ignition point. The molten metal is then blown away by a high-pressure oxygen stream to achieve cutting.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] The first embodiment, as Figures 1 to 2 and Figures 7 to 9 As shown, the present invention provides a technical solution:

[0031] A cutting device for building steel structures with a synchronous dust removal function, comprising:

[0032] The frame 1 has an air pump 6 fixedly mounted on the top of the frame 1, and a conducting pipe 5 is mounted at the air inlet of the air pump 6;

[0033] The guiding mechanism 3 is installed at the center of the top of the frame 1. The limiting mechanisms 4 are installed on both sides of the guiding mechanism 3. The limiting mechanisms 4 cooperate with the guiding mechanism 3 to move and position the material;

[0034] The cutting mechanism 2 is used to cut the material and absorb the smoke generated by the cutting. The cutting mechanism 2 is installed on the top of the frame 1;

[0035] Among them, the cutting mechanism 2 includes a fixed frame 201, and an air guide cylinder 203 is fixedly installed at the center position of the top of the fixed frame 201. The top of the air guide cylinder 203 is fixedly connected to the end of the guide pipe 5 away from the air pump 6, and the top of the inner wall of the air guide cylinder 203 is fixedly connected to the arc disk 208, and the inner wall of the arc disk 208 is fixedly connected to the through-groove cylinder 207. The outer side of the through-groove cylinder 207 is evenly provided with through grooves, and the outer side of the through-groove cylinder 207 is fixedly installed with a filter cartridge 209. The inner wall of the air guide cylinder 203 is fixedly connected to the arc groove disk 211. Driven by the air pump 6, the smoke dust passes through the arc groove of the arc groove disk 211 through the gap between the outer cover cylinder 212 and the inner pad 213, so that the smoke dust enters between the filter cartridge 209 and the conical cylinder 210. Through the filtering effect of the filter cartridge 209, the filter cartridge 209 blocks the dust in the smoke. Dust particles and gas pass through the filter cartridge 209 into the interior of the through-groove cartridge 207, and are introduced into the suction pump 6 by the guide pipe 5 at the top of the air guide cartridge 203, and are directionally guided and collected by the suction pump 6. After the dust particles in the smoke are blocked, they move upward under the action of the air flow, and the outer diameter of the conical cylinder 210 changes, so that the distance between the conical cylinder 210 and the filter cartridge 209 gradually decreases from bottom to top, thereby accelerating the air flow rate and driving the dust to contact the arc disk 208. The arc surface of the arc disk 208 is used to guide the dust particles into the space between the conical cylinder 210 and the air guide cartridge 203 for collection. The top of the arc groove disk 211 is fixedly connected with the conical cylinder 210, and the inner diameter of the conical cylinder 210 gradually increases from top to bottom. The conical cylinder 210 is located on the outside of the filter cartridge 209 and the gap between it and the filter cartridge 209 gradually increases from top to bottom.

[0036] The top of the arc groove disk 211 is evenly provided with arc grooves, and the bottom of the arc groove disk 211 is fixedly installed with an outer cover tube 212 and an inner pad 213. The outer cover tube 212 is located on the outside of the inner pad 213, and the outer diameter of the inner pad 213 gradually increases from top to bottom. During the cutting process, the smoke generated by the cutting is driven by the vacuum pump 6 to flow upward, and the smoke is caused to surge upward from the gap between the outer cover tube 212 and the inner pad 213. At the same time, in the process of pumping the smoke, the outer diameter of the inner pad 213 is gradually increased from top to bottom, so that the gap between the inner pad 213 and the outer cover tube 212 is gradually reduced from top to bottom, thereby increasing the suction force on the bottom cutting position, and the bottom of the inner pad 213 is a raised arc surface at the center position, and the center position of the top of the inner wall of the fixed frame 201 A cover plate 205 is fixedly connected to the frame 201, and grooves are provided on both sides of the cover plate 205, and cutting guns 204 are slidably installed at the grooves of the cover plate 205. When the I-beam is driven to make the cutting position reach the position of the cutting gun 204, the cutting gun 204 is used to spray a flame flow to cut the I-beam. At the same time, during the cutting process, the cutting gun 204 is driven by the cylinder 202 to slide up and down at the grooves of the cover plate 205, changing the cutting position to cut the I-beam. The cylinder 202 is fixedly connected to both sides of the top of the fixed frame 201, and the output end of the cylinder 202 passes through the fixed frame 201 and extends to its bottom, and the output end of the cylinder 202 is fixedly connected to the outer side of the cutting gun 204. Side baffles 206 are fixedly installed on both sides of the inner wall of the cover plate 205.

[0037] The second embodiment, based on the first embodiment, see Figures 3 and 4As shown, the guide mechanism 3 includes a bottom plate 301, the bottom plate 301 is fixedly mounted on the top of the frame 1, and the top of the bottom plate 301 is fixedly mounted with an axis frame 302 and a support frame 303, and there is a gap between the support frame 303 and the axis frame 302, and the inner wall of the axis frame 302 is fixedly connected to the end of the support frame 303, and the motor 304 drives the rotating shaft 305 to rotate through the belt 306, so that the rotating shaft 305 cooperates with the rubber ring 308, and during the rotation process, drives the I-beam placed on the top thereof to move, so that the cutting position of the I-beam reaches the cutting mechanism 2, and at the same time, during the movement process, cooperates with the limiting mechanism 4 to limit the position of the I-beam, and the inner wall of the axis frame 302 is rotatably mounted with the rotating shaft 305, and the rotating shaft 305 is evenly installed along the axial direction, and the center position of the outer side of the rotating shaft 305 is fixedly connected to the groove wheel 307, and the two ends of the outer side of the groove wheel 307 are provided with annular grooves. When the cutting position is reached, the I-beam at the other end is The other end is supported by the support wheel 309, and the I-beam is restricted at the groove on the top of the I-beam by the pressure wheel 310, so that the cut section of the I-beam is restricted, and the ring groove of the groove wheel 307 is fixedly installed with a rubber ring 308, and the outer side of the rubber ring 308 is evenly provided with protrusions. The output end of the motor 304 is installed with a belt 306, and the motor 304 is connected to one end of the rotating shaft 305 through the belt 306. Both sides of the support frame 303 are fixedly installed. There is a support plate 311. When the rotating shaft 305 rotates to drive the I-beam, the gravity of the I-beam itself presses the rubber ring 308, causing the bulge on the outside of the rubber ring 308 to deform, thereby increasing the contact area with the I-beam and making the top of the groove wheel 307 contact the groove at the bottom of the I-beam. A pressure wheel 310 is rotatably installed between the support plates 311, and a support wheel 309 is rotatably installed on the inner wall of the support frame 303. The top of the support wheel 309 is flush with the top of the groove wheel 307.

[0038] The third embodiment, based on the first and second embodiments, see Figures 5 and 6 As shown, the limiting mechanism 4 includes a connecting plate 41, which is fixedly mounted on the outer side of the guide mechanism 3, and the top of the connecting plate 41 is fixedly connected to a slide frame 42, and a slide groove is symmetrically opened on the top of the slide frame 42, and side pressure wheels 49 are slidably mounted on the slide grooves of the slide frame 42. During the movement of the I-beam, the side pressure wheels 49 contact the two sides of the I-beam through the elastic deformation of the spring 44, so that the elastic force passes through the slide plate 45 and the fixed plate 46, cooperates with the shaft 48 and the sleeve plate 47, and drives the side pressure wheels 49 to clamp the I-beam with the same force on both sides, so that the I-beam is in the center position of the guide mechanism 3, and a wheel axle is provided on the top of the side pressure wheel 49, and the side pressure wheel 49 slides and adapts to the slide groove of the slide frame 42 through the wheel axle, and the side pressure wheel 49 is fixedly connected to the sleeve plate 47 through the wheel axle, and the bottom of the sleeve plate 47 is tightly fitted with the top of the slide frame 42.

[0039] The outer side of the sleeve plate 47 is fixedly connected to a shaft rod 48, and the end of the shaft rod 48 away from the sleeve plate 47 is fixedly connected to a fixed plate 46, and the bottom of the fixed plate 46 is fixedly connected to a slide plate 45. Slide holes are provided at both ends of the outer side of the slide plate 45, and slide rods 43 are fixedly installed on the outer side of the connecting plate 41. When the I-beam tends to tilt during movement, the slide rod 43 restricts the slide plate 45, so that the fixed plate 46 cannot tilt, thereby limiting the tilt of the I-beam. The outer side of the slide rod 43 is slidably adapted to the slide hole of the slide plate 45, and a spring 44 is fixedly installed between the slide plate 45 and the connecting plate 41, and the spring 44 is located on the outer side of the slide rod 43.

[0040] During use, workers place the I-beam required for the steel structure to be cut into the guiding mechanism 3, which drives the I-beam to move and cooperates with the limiting mechanism 4 to position the I-beam so that the I-beam always remains in the center position of the guiding mechanism 3 during the movement. When the cutting position of the I-beam reaches the cutting mechanism 2, the I-beam is cut by the cutting mechanism 2. At the same time, when the cutting mechanism 2 is cutting the I-beam, the vacuum pump 6 absorbs the smoke generated by the cutting through the conducting pipe 5, and cooperates with the cutting mechanism 2 to remove dust.

[0041] In the cutting mechanism 2, when the I-beam is driven and the cutting position reaches the position of the cutting gun 204, the cutting gun 204 is used to eject a flame flow to cut the I-beam. At the same time, during the cutting process, the cylinder 202 drives the cutting gun 204 to slide up and down at the groove of the cover plate 205, changing the cutting position to cut the I-beam. At the same time, during the cutting process, the smoke generated by the cutting is driven by the vacuum pump 6 to flow upward, so that the smoke is surged upward from the gap between the outer cover tube 212 and the inner pad 213. At the same time, in the process of pumping the smoke, the outer diameter of the inner pad 213 is gradually increased from top to bottom, so that the gap between the inner pad 213 and the outer cover tube 212 is gradually reduced from top to bottom, thereby increasing the suction force on the bottom cutting position. Driven by the vacuum pump 6, the smoke is discharged from the outer cover tube 21 The gap between 2 and the inner pad 213 passes through the arc groove of the arc groove disk 211, allowing the smoke to enter between the filter cartridge 209 and the conical cylinder 210. Through the filtering effect of the filter cartridge 209, the filter cartridge 209 blocks the dust particles in the smoke. The gas passes through the filter cartridge 209 and enters the interior of the through-grooved cylinder 207, and is introduced into the air pump 6 through the guide pipe 5 at the top of the air guide cylinder 203. It is directionally guided and collected by the air pump 6. After the dust particles in the smoke are blocked, they move upward under the action of the air flow. With the change of the outer diameter of the conical cylinder 210, the distance between the conical cylinder 210 and the filter cartridge 209 gradually decreases from bottom to top, which accelerates the air flow rate and drives the dust to contact the arc disk 208. The arc surface of the arc disk 208 is used to guide the dust particles into the space between the conical cylinder 210 and the air guide cylinder 203 for collection.

[0042] In the guiding mechanism 3, the motor 304 drives the rotating shaft 305 to rotate through the belt 306, so that the rotating shaft 305 cooperates with the rubber ring 308. During the rotation process, the I-beam placed on the top of it is driven to move, so that the cutting position of the I-beam reaches the cutting mechanism 2. At the same time, during the movement process, it cooperates with the limiting mechanism 4 to limit the position of the I-beam. When the cutting position is reached, the other end of the I-beam is supported by the supporting wheel 309. At the same time, the I-beam is restricted at the groove at the top of the I-beam by the pressing wheel 310, so that the cut section of the I-beam is restricted. At the same time, when the rotating shaft 305 rotates and drives the I-beam, the gravity of the I-beam itself presses the rubber ring 308, causing the bulge on the outside of the rubber ring 308 to deform, thereby increasing the contact area with the I-beam and making the top of the groove wheel 307 contact the groove at the bottom of the I-beam.

[0043] In the limiting mechanism 4, during the movement of the I-beam, the side pressure wheels 49 contact the two sides of the I-beam, and the elastic deformation of the spring 44 is used to make the elastic force pass through the slide plate 45 and the fixed plate 46, cooperate with the shaft 48 and the sleeve plate 47, and drive the side pressure wheels 49 to clamp the I-beam with the same force on both sides, so that the I-beam is in the center position of the guiding mechanism 3. When the I-beam tends to tilt during the movement, the sliding rod 43 restricts the slide plate 45, so that the fixed plate 46 cannot tilt, thereby limiting the tilt of the I-beam.
