Description

Technical Field

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

[0002] Building steel structures refer to a structural system formed by connecting steel plates and steel sections through welding, bolt connection or riveting, etc. It mainly consists of steel sections and steel plates. These steel materials are processed into various components, including beams, columns, trusses, grids, etc. For example, in high-rise buildings, steel columns bear vertical loads, and steel beams transfer floor loads to steel columns. The cutting equipment for building steel structures mainly uses flame cutting. Flame cutting is to use the high-temperature flame generated by the combustion of gas and oxygen to heat the surface of the steel to the ignition point, and then blow away the molten metal through a high-pressure oxygen stream to achieve cutting. During the process of cutting and dust removal, an air pump is used to pump the dust at the cutting position to avoid the diffusion of dust. However, during the air extraction process, the particles in the dust are likely to block the pipeline, resulting in a reduction in the dust removal effect. Summary of the Invention

[0007] Among them, the cutting mechanism includes a fixed frame. At the central position of the top of the fixed frame, an air guide cylinder is fixedly installed. The top of the air guide cylinder is fixedly connected to one end of the conduction pipe away from the air extraction pump. And at the top of the inner wall of the air guide cylinder, an arc-shaped disk is fixedly connected. Inside the arc-shaped disk, a through-channel cylinder is fixedly connected.

For the cutting device for building steel structures with a synchronous dust removal function, through the conical shape of the conical cylinder, when filtering, in cooperation with the filter cartridge, the gap gradually decreases from bottom to top, increasing the air flow rate during filtering, causing the blocked dust particles to continue to surge upward driven by the air, and making the blocked dust particles cooperate with the arc surface of the arc surface disc under the drive of the air, guiding the dust particles into the gap between the conical cylinder and the air guide cylinder for collection.

[0014] 3. For the cutting device for building steel structures with a synchronous dust removal function, through the support cooperation between the grooved pulley and the rubber wheel, after placing the I-beam at the top, using the gravity of the I-beam itself, the I-beam presses the rubber ring, causing the rubber ring to deform. At the same time, the groove at the bottom of the I-beam contacts the grooved pulley, enabling the grooved pulley to support the I-beam. While ensuring that the I-beam is parallel to the horizontal plane, the deformation of the rubber ring increases the contact area with the I-beam, avoiding sliding while moving and causing errors in the cutting position.

Specific embodiments

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] The first embodiment is as Figures 1 to 2 and Figures 7 to 9 shown, the present invention provides a technical solution: A cutting device for building steel structures with a synchronous dust removal function, comprising: A frame body 1, on the top of which an air extraction pump 6 is fixedly installed, and a conduction pipe 5 is installed at the air inlet of the air extraction pump 6; A feeding mechanism 3 is installed at the central position on the top of the frame body 1. Limiting mechanisms 4 are installed on both sides of the feeding mechanism 3. The limiting mechanisms 4 cooperate with the feeding mechanism 3 to move and position the material. A cutting mechanism 2 is used to cut the material and absorb the smoke and dust generated by the cutting. The cutting mechanism 2 is installed on the top of the frame body 1. Among them, the cutting mechanism 2 includes a fixed frame 201. A gas guide cylinder 203 is fixedly installed at the central position on the top of the fixed frame 201. The top of the gas guide cylinder 203 is fixedly connected to one end of the conduction pipe 5 away from the air extraction pump 6. And the top of the inner wall of the gas guide cylinder 203 is fixedly connected with a cambered surface disk 208. The inner wall of the cambered surface disk 208 is fixedly connected with a through groove cylinder 207. The outer side of the through groove cylinder 207 is evenly provided with through grooves. And a filter cylinder 209 is fixedly installed on the outer side of the through groove cylinder 207. An arc groove disk 211 is fixedly connected to the inner wall of the gas guide cylinder 203. Driven by the air extraction pump 6, the smoke and dust pass through the arc grooves of the arc groove disk 211 from the gap between the outer cover cylinder 212 and the inner cushion block 213, so that the smoke and dust enter between the filter cylinder 209 and the conical cylinder 210. Through the filtering effect of the filter cylinder 209, the filter cylinder 209 blocks the dust particles in the smoke and dust. The gas passes through the filter cylinder 209 and enters the inside of the through groove cylinder 207, and is introduced into the air extraction pump 6 through the conduction pipe 5 at the top of the gas guide cylinder 203, and is directionally exported and collected through the air extraction pump 6. After the dust particles in the smoke and dust are blocked, under the action of air flow, they move upward. Cooperating with the change of the outer diameter of the conical cylinder 210, the distance between the conical cylinder 210 and the filter cylinder 209 gradually decreases from bottom to top, accelerating the air flow rate, driving the dust to contact the cambered surface disk 208, and using the cambered surface of the cambered surface disk 208 to introduce the dust particles into the space between the conical cylinder 210 and the gas guide cylinder 203 for collection. A conical cylinder 210 is fixedly connected to the top of the arc groove disk 211. The inner diameter of the conical cylinder 210 gradually increases from top to bottom. And the conical cylinder 210 is located outside the filter cylinder 209 and the gap between the conical cylinder 210 and the filter cylinder 209 gradually increases from top to bottom.

[0021] 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 cover plate 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 flames 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 to change the cutting position and cut the I-beam. Cylinders 202 are 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 the bottom thereof, and the output end of the cylinder 202 is fixedly connected to the outer side of the cutting gun 204, and side baffles 206 are fixedly installed on both sides of the inner wall of the cover plate 205.

[0022] The second embodiment is based on the first embodiment. Figures 3 to 4As shown in the figure, the feeding mechanism 3 includes a bottom plate 301, which is fixedly installed at the top of the frame body 1. At the top of the bottom plate 301, a shaft frame 302 and a support frame 303 are fixedly installed. There is a gap between the support frame 303 and the shaft frame 302. At one end of the inner wall of the shaft frame 302 away from the support frame 303, a motor 304 is fixedly connected. The motor 304 drives the rotation of a rotating shaft 305 through a belt 306, so that the rotating shaft 305 cooperates with a rubber ring 308. During the rotation process, the I-beam placed on its top is driven to move, so that the cutting position of the I-beam reaches the cutting mechanism 2. At the same time, during the moving process, it cooperates with the limiting mechanism 4 to limit the position of the I-beam. The rotating shaft 305 is rotatably installed on the inner wall of the shaft frame 302. The rotating shafts 305 are evenly installed along the axial direction, and at the central position on the outer side of the rotating shaft 305, a sheave 307 is fixedly connected. At both ends on the outer side of the sheave 307, annular grooves are provided. When reaching the cutting position, the other end of the other I-beam is supported by a support wheel 309. At the same time, the I-beam is restricted through a pressure wheel 310 at the groove on the top of the I-beam, so that the cut section of the I-beam is restricted. And rubber rings 308 are fixedly installed at the annular grooves of the sheave 307. The outer side of the rubber ring 308 is evenly provided with protrusions. The output end of the motor 304 is equipped with a belt 306, and the motor 304 is drivingly connected to one end of the rotating shaft 305 through the belt 306. On both sides of the support frame 303, support plates 311 are fixedly installed. When the rotating shaft 305 drives the I-beam to rotate, due to the self-gravity of the I-beam, when pressing the rubber ring 308, the protrusions on the outer side of the rubber ring 308 are deformed, increasing the contact area with the I-beam, so that the top of the sheave 307 contacts 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 sheave 307.

[0023] The third embodiment is based on the first and second embodiments. Please refer to Figures 5 to 6 As shown in the figure, the limiting mechanism 4 includes a connecting plate 41, which is fixedly installed on the outer side of the feeding mechanism 3. And at the top of the connecting plate 41, a sliding groove frame 42 is fixedly connected. At the top of the sliding groove frame 42, sliding grooves are symmetrically provided. And side pressure wheels 49 are slidably installed at the sliding grooves of the sliding groove frame 42. During the movement of the I-beam, through the contact of the side pressure wheels 49 with both sides of the I-beam, by the elastic deformation of a spring 44, the elastic force passes through a sliding plate 45 and a fixing plate 46, and cooperates with a shaft rod 48 and a sleeve plate 47 to 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 central position of the feeding mechanism 3. The top of the side pressure wheel 49 is provided with a wheel shaft, and the side pressure wheel 49 is slidably adapted to the sliding groove of the sliding groove frame 42 through the wheel shaft. The side pressure wheel 49 is fixedly connected with a sleeve plate 47 through the wheel shaft. The bottom of the sleeve plate 47 is closely attached to the top of the sliding groove frame 42.

[0024] A shaft rod 48 is fixedly connected to the outer side of the template 47. One end of the shaft rod 48 away from the template 47 is fixedly connected to a fixing plate 46. A sliding plate 45 is fixedly connected to the bottom of the fixing plate 46. Sliding holes are formed at both ends of the outer side of the sliding plate 45. Slide bars 43 are fixedly installed on the outer sides of the connecting plates 41. When the I-beam has a tendency to tilt during movement, the fixing plate 46 is prevented from tilting by the restriction of the slide bars 43 on the sliding plate 45, restricting the tilt of the I-beam. The outer sides of the slide bars 43 are slidably adapted to the sliding holes of the sliding plate 45, and a spring 44 is fixedly installed between the sliding plate 45 and the connecting plates 41. The spring 44 is located on the outer side of the slide bars 43.

[0025] During use, the worker places the I-beam required for cutting the steel structure into the feeding mechanism 3. The feeding mechanism 3 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 at the central position of the feeding mechanism 3 during movement. When the cutting position of the I-beam reaches the cutting mechanism 2, the cutting mechanism 2 cuts the I-beam. At the same time, when the cutting mechanism 2 cuts the I-beam, the air extraction pump 6 absorbs the dust generated by cutting through the conduction pipe 5, cooperating with the cutting mechanism 2 for dust removal.

[0026] In the cutting mechanism 2, when the I-beam is driven and the cutting position reaches the position of the cutting torch 204, the cutting torch 204 sprays a flame flow to cut the I-beam. At the same time, during the cutting process, the cutting torch 204 is driven by the cylinder 202 to slide up and down at the slot of the cover plate 205, changing the cutting position to cut the I-beam. At the same time, during the cutting process, driven by the air extraction pump 6, the dust generated by cutting flows upward, and the dust surges upward through the gap between the outer cover cylinder 212 and the inner spacer 213. At the same time, during the process of pumping the dust, since the outer diameter of the inner spacer 213 gradually increases from top to bottom, the gap between the inner spacer 213 and the outer cover cylinder 212 gradually decreases from top to bottom, increasing the suction force at the bottom cutting position. Driven by the air extraction pump 6, the dust passes through the arc grooves of the arc groove disc 211 through the gap between the outer cover cylinder 212 and the inner spacer 213, and the dust enters between the filter cylinder 209 and the conical cylinder 210. Through the filtering action of the filter cylinder 209, the filter cylinder 209 blocks the dust particles in the dust, and the gas passes through the filter cylinder 209 and enters the inside of the through groove cylinder 207, and is introduced into the air extraction pump 6 through the conduction pipe 5 at the top of the air guide cylinder 203 and is collected by the air extraction pump 6 in a directional manner. After the dust particles in the dust are blocked, they move upward under the action of air flow. Cooperating with the change in the outer diameter of the conical cylinder 210, the distance between the conical cylinder 210 and the filter cylinder 209 gradually decreases from bottom to top, accelerating the air flow rate, driving the dust to contact the arc surface disc 208, and using the arc surface of the arc surface disc 208 to introduce the dust particles into the space between the conical cylinder 210 and the air guide cylinder 203 for collection.

[0027] In the feeding 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, the I-beam placed on its top 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, it cooperates with the limiting mechanism 4 to limit the position of the I-beam. When reaching the cutting position, the other end of the I-beam at the other end is supported by the supporting wheel 309. At the same time, the I-beam is restricted by the pressing wheel 310 at the groove on the top of the I-beam, so that the cut section of the I-beam is restricted. At the same time, when the rotating shaft 305 drives the I-beam to rotate, due to the gravity of the I-beam itself, when pressing the rubber ring 308, the protrusions on the outer side of the rubber ring 308 are deformed, increasing the contact area with the I-beam, so that the top of the grooved pulley 307 contacts the groove at the bottom of the I-beam.

[0028] In the limiting mechanism 4, during the movement of the I-beam, the side pressing wheels 49 contact the two sides of the I-beam. By the elastic deformation of the spring 44, the elastic force passes through the sliding plate 45 and the fixing plate 46, and cooperates with the shaft rod 48 and the sleeve plate 47 to drive the side pressing wheels 49 to clamp the I-beam with the same force on both sides, so that the I-beam is in the central position of the feeding mechanism 3. When the I-beam has a tendency to tilt during the movement, through the restriction of the sliding rod 43 on the sliding plate 45, the fixing plate 46 cannot tilt, restricting the tilt of the I-beam.
