Description

Technical Field

[0001] This invention relates to the field of bridge steel cutting technology, and specifically to a cutting device for bridge steel structures. Background Technology

[0002] Bridge steel structure refers to the use of steel as the main construction material in bridge construction. Utilizing its high strength and good toughness, steel forms the main load-bearing structure of the bridge. As a crucial component of transportation infrastructure, bridge steel structure plays an increasingly important role in modern transportation construction. With continuous technological advancements and strong policy support, bridge steel structure will have even greater development potential in the future, providing solid support for promoting the green, intelligent, and efficient development of transportation infrastructure.

[0003] In the prior art, when a cutting machine is used to cut a bridge steel structure, the high-speed rotating blade comes into contact with the bridge steel structure and generates friction. At this time, the temperature of the blade and the bridge steel structure will rise accordingly. Therefore, the bridge steel structure may expand due to heat during cutting and shrink after cooling, resulting in inaccurate dimensions of the bridge steel structure. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a cutting device for bridge steel structures to solve the problems mentioned in the background section.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] A cutting device for bridge steel structures includes a cutting table, a water storage tank fixedly installed on the bottom surface of the cutting table, a movable platform inside the cutting table, sliding blocks fixedly installed on both sides of the movable platform, a support platform fixedly installed on the top surface of the movable platform, and a mounting shell inside the support platform; adjustment components for adjusting the water spray angle are provided on both sides of the mounting shell; displacement components for moving the movable platform are provided on both sides of the cutting table; and a cooling component, located inside one side of the mounting shell, for cooling the bridge steel structure during cutting, the cooling component including: an extension column fixedly installed inside one side of the mounting shell, a movable frame inside the mounting shell, a movable hole on one side of the extension column, a support hole on one side of the movable frame, a bearing fixedly sleeved on the inner circular wall of the movable hole, a stabilizing column fixedly sleeved on the inner circular wall of the bearing inner ring, and a limit ring fixedly sleeved on the outer circular wall of the stabilizing column. A cutting blade is provided on the outer circular wall of the column. A transmission column is fixedly installed at one end of the stabilizing column, and a driven pulley is fixedly installed at one end of the transmission column. A servo motor is fixedly installed on the top surface of the moving platform. A main pulley is fixedly installed at one end of the servo motor drive shaft. A V-belt is wound around the outer circular wall of the main pulley and the driven pulley. A water pump is fixedly installed on the inner bottom surface of the cutting platform. A water outlet is opened on one side of the water tank, and a water outlet pipe is fixedly sleeved on the inner circular wall of the water outlet. The water outlet pipe is fixedly connected to the water inlet of the water pump. A telescopic hose is fixedly connected to the inner circular wall of the water pump outlet. A diversion pipe is provided on the top surface of the mounting housing. A water inlet hole is opened on the outer circular wall of the diversion pipe. The water inlet hole is fixedly connected to the telescopic hose. Two circular through holes are opened on the outer circular wall of the diversion pipe. A rubber hose is fixedly connected to the inner circular wall of the circular through hole. A drain pipe is fixedly connected to the outer circular wall of the rubber hose. A nozzle is fixedly connected to the inner circular wall of the drain pipe.

[0007] By adopting the above technical solution, and with the designed cutting blade, when the worker cuts the bridge steel, the bridge steel is placed on the top surface of the cutting table. The worker then uses a servo motor; the drive shaft of the servo motor rotates, which in turn drives the main pulley to rotate. The rotation of the main pulley, in turn, drives the driven pulley to rotate via a V-belt. The driven pulley then drives the transmission column, stabilizing column, and cutting blade to rotate, bringing the cutting blade close to the bridge steel for easier cutting. Before cutting the bridge steel, cutting fluid is added to the water tank. When the cutting blade cuts the bridge steel, the fluid propelled by the cutting blade will... The drain pipe and nozzle are brought close to the bridge steel. At this time, the worker uses a water pump to draw cutting fluid through the outlet pipe and discharge it through the telescopic hose into the inside of the diversion pipe and rubber hose. It then enters the drain pipe and is sprayed out through the nozzle. The cutting fluid is then sprayed onto the surface of the bridge steel and works in conjunction with the cutting blade to cut the bridge steel. This facilitates the cooling of the bridge steel during cutting and lubricates the cutting blade and bridge steel, improving the cutting effect. At the same time, the use of cutting fluid can reduce friction and tool wear caused by high temperature, maintain the hardness and cutting performance of the tool, and prevent the bridge steel from expanding due to heat and contracting after cooling, which would lead to inaccurate dimensions.

[0008] Preferably, the adjustment assembly includes: two shielding shells, which are respectively fixedly installed on both sides of the mounting shell. An installation plate is fixedly installed inside each shielding shell. An adjustment hole is formed on the top surface of the installation plate. The drain pipe is movably sleeved with the adjustment hole. A limiting ring is provided on the top surface of the installation plate. Several slots are formed on the inner circular wall of the limiting ring. The installation ring is fixedly sleeved on the outer circular wall of the drain pipe. An adjustment ring is fixedly sleeved on the outer circular wall of the drain pipe. Several locking posts are fixedly installed on the outer circular wall of the adjustment ring. The locking posts are movably locked with the slots. The limiting ring is movably sleeved with the adjustment ring. A locking block is fixedly installed on the outer circular wall of the limiting ring. A locking shell is fixedly installed on the top surface of the installation plate. The locking block is movably sleeved with the locking shell.

[0009] By adopting the above technical solution, through the setting of the limiting ring, the operator moves the limiting ring upward to drive the snap-fit ​​block to move, thereby moving the snap-fit ​​block out of the snap-fit ​​housing. At this time, the snap-fit ​​post will also disengage from the snap-fit ​​groove, thus releasing the restriction on the drain pipe and the adjusting ring. Subsequently, the operator can rotate the drain pipe to drive the nozzle and the adjusting ring to rotate. After the nozzle has rotated, the operator moves the limiting ring downward to drive the snap-fit ​​block to move, so that the snap-fit ​​block re-enters the snap-fit ​​housing and the snap-fit ​​post snaps into the snap-fit ​​groove. This can restrict the drain pipe and the adjusting ring, thereby facilitating the rotation and adjustment of the nozzle's spray angle.

[0010] Preferably, the displacement component includes: two transmission holes, each located on one side of the cutting table; a transmission rod movably sleeved on the inner circular wall of each transmission hole; two first transmission wheels fixedly sleeved on the outer circular wall of each transmission rod; positioning holes on both sides of the cutting table; a movable column movably sleeved on the inner circular wall of each positioning hole; a second transmission wheel fixedly installed at one end of each movable column; each second transmission wheel and each first transmission wheel forming a group; a first belt wound around the outer circular wall of each group of first and second transmission wheels; rotating holes on both sides of the cutting table; a rotating column movably sleeved on the inner circular wall of each rotating hole; a driven synchronizing wheel fixedly sleeved on the outer circular wall of each rotating column; a main synchronizing wheel fixedly sleeved on the outer circular wall of each movable column; the main synchronizing wheel and the driven synchronizing wheel on the same side forming a group; a synchronous belt wound around the outer circular wall of each group of main and driven synchronizing wheels; and a sliding block fixedly installed with the synchronous belt.

[0011] By adopting the above technical solution, through the transmission rod, the operator rotates the transmission rod to drive the two first transmission wheels to rotate. The two first transmission wheels then drive the two second transmission wheels to rotate through the two first belts. When the second transmission wheels rotate, they drive the movable column and the main synchronous wheel to rotate. In turn, the main synchronous wheel drives the secondary synchronous wheel and the rotating column to rotate through the synchronous belt. At this time, the synchronous belts on both sides inside the cutting table will move. When the upper end of the synchronous belt moves, it will drive the sliding block and the moving table to move, so that the cutting blade can slowly approach the bridge steel, thereby facilitating the movement of the cutting blade to cut the bridge steel.

[0012] Preferably, the support platform has limit grooves on both sides of its interior, and limit blocks are fixedly installed on both sides of the mounting shell. The limit blocks are movably sleeved with the limit grooves. A fixing hole is provided on one side of the support platform, and a bolt is movably sleeved on the inner circular wall of the fixing hole. A plurality of first threaded grooves are provided on one side of the mounting shell, and the bolts are threadedly connected to the first threaded grooves.

[0013] By adopting the above technical solution, and by setting the bolt, the operator can move the bolt out of the fixing hole and the first threaded groove, and then move the mounting shell upward to drive the cutting blade to move, thereby raising the position of the cutting blade. Then, the bolt is inserted through the fixing hole into the first threaded groove and tightened, which facilitates the adjustment of the cutting height of the cutting blade.

[0014] Preferably, the outer circular wall of the stabilizing column is threaded, and a fixing column is provided on the outer circular wall of the stabilizing column. One end of the fixing column is provided with a second threaded groove, which is threadedly connected to the stabilizing column. A rotating hole is provided on one side of the movable frame, and a connecting column is fixedly installed on one side of the extension column. The connecting column is movably sleeved with the rotating hole.

[0015] By adopting the above technical solution, through the fixed column, the worker can loosen it on the surface of the stabilizing column by rotating the fixed column, thereby moving the fixed column away from one end of the stabilizing column. Then, the worker can rotate the movable frame around the connecting column, and then move the movable frame away from one side of the cutting blade. At this time, the worker can move the cutting blade to remove it from the surface of the stabilizing column, which makes it easy to disassemble and replace the cutting blade.

[0016] Preferably, guide posts are fixedly installed on both sides of the inside of the cutting table, and a guide hole is opened on one side of the sliding block, and the guide hole is movably connected with the guide post.

[0017] By adopting the above technical solution, the supporting force on the sliding block and the moving platform is increased so that the sliding block can move smoothly.

[0018] Preferably, the inner bottom surface of the cutting table is provided with a water storage tank, the inner bottom surface of the water storage tank is provided with a water flow hole, a circulation pipe is fixedly sleeved on the inner circular wall of the water flow hole, and a circulation hole is provided on one side of the water storage tank, the circulation pipe is fixedly sleeved with the circulation hole.

[0019] By adopting the above technical solution, and through the set water storage tank, when the cutting fluid is sprayed onto the bridge steel being cut, the cutting fluid will flow back into the water storage tank through the water outlet and circulation pipe, thus facilitating the recycling of the cutting fluid.

[0020] Preferably, the water storage tank has resistance grooves on both sides inside, a filter screen is movably fitted inside the water storage tank, and a snap-fit ​​plate is fixedly installed on both sides of the filter screen, the snap-fit ​​plate being movably snapped into the resistance groove.

[0021] The above technical solution is used to filter the circulating cutting fluid.

[0022] Preferably, two limiting frames are fixedly installed on the top surface of the cutting table. Adjustment grooves are respectively opened on both sides of the limiting frames. Adjustment columns are movably sleeved inside the adjustment grooves. A stabilizing frame is fixedly installed on the top surface of the adjusting column. A threaded hole is opened on the top surface of the stabilizing frame. The inner circular wall of the threaded hole is threaded. A fastening column is threaded to the inner circular wall of the threaded hole. The outer circular wall of the fastening column is threaded. A rubber block is fixedly installed on the bottom surface of the fastening column.

[0023] By adopting the above technical solution, when workers cut bridge steel using the rubber block, they first place the rubber block inside the limiting frame, then move the adjusting column to move the stabilizing frame and the fastening column, adjusting the position of the fastening column and the rubber block so that the rubber block is on the top surface of the bridge steel. Then, workers rotate the fastening column to rotate the rubber block, bringing the rubber block closer to the top surface of the bridge steel, and tighten the fastening column, thus facilitating the clamping of the bridge steel.

[0024] In summary, the present invention has the following main beneficial effects:

[0025] The cutting table, moving table, support table, mounting shell, extension column, movable frame, movable hole, stabilizing column, limit ring, cutting blade, transmission column, driven pulley, servo motor, main pulley, and V-belt work together to bring the cutting blade close to the bridge steel, thus facilitating cutting. The water tank, water pump, water outlet, water pipe, telescopic hose, diverter pipe, rubber hose, drain pipe, and nozzle work together to cool the bridge steel during cutting and lubricate the cutting blade and bridge steel, improving the cutting effect. Simultaneously, the use of cutting fluid reduces friction and tool wear caused by high temperatures, maintains tool hardness and cutting performance, and prevents the bridge steel from expanding due to heat and contracting after cooling, thus avoiding dimensional inaccuracies.

[0026] The locking block, locking shell, locking post, locking groove, drain pipe, and adjusting ring work together through the setting of the limiting ring to release the restriction on the drain pipe and adjusting ring. Then, rotating the drain pipe drives the nozzle and adjusting ring to rotate. After the nozzle has rotated, the locking block is moved by moving the limiting ring downward, so that the locking block re-enters the interior of the locking shell and the locking post locks into the interior of the locking groove to restrict the drain pipe and adjusting ring, thereby facilitating the rotation and adjustment of the nozzle's spray angle.

The cooling component includes an extension column 6 fixedly installed inside one side of the mounting shell 5, and a movable frame 7 inside the mounting shell 5. A movable hole 8 is provided on one side, and a support hole 9 is provided on one side of the movable frame 7. A bearing is fixedly sleeved on the inner circular wall of the movable hole 8. A stabilizing column 10 is fixedly sleeved on the inner circular wall of the bearing inner ring. A limit ring 11 is fixedly sleeved on the outer circular wall of the stabilizing column 10. A cutting blade 12 is provided on the outer circular wall of the stabilizing column 10. A transmission column 13 is fixedly installed at one end of the stabilizing column 10. A driven pulley 14 is fixedly installed at one end of the transmission column 13. A servo motor 15 is fixedly installed on the top surface of the moving table 3. A main pulley 16 is fixedly installed at one end of the drive shaft of the servo motor 15. A V-belt 17 is wound around the outer circular walls of the main pulley 16 and the driven pulley 14. A water pump 18 is fixedly installed on the inner bottom surface of the cutting table 1. A water outlet 19 is provided on one side of the water tank 2.

A water inlet hole 23 is opened on the outer circular wall of the diversion pipe 22. The water inlet hole 23 is fixedly sleeved with the telescopic hose 21. Two circular through holes are opened on the outer circular wall of the diversion pipe 22. A rubber hose 25 is fixedly sleeved on the inner circular wall of the circular through holes. A drain pipe 26 is fixedly sleeved on the outer circular wall of the rubber hose 25. A nozzle 27 is fixedly sleeved on the inner circular wall of the drain pipe 26. When the worker cuts the bridge steel using the cutting blade 12, the bridge steel is placed on the top surface of the cutting table 1, and then... The operator uses servo motor 15, whose drive shaft rotates to rotate main pulley 16. This rotation, via V-belt 17, drives secondary pulley 14, which in turn rotates drive column 13, stabilizer column 10, and cutting blade 12. The cutting blade 12 is then brought close to the bridge steel for easier cutting. Before cutting, cutting fluid is added to water tank 2. When the cutting blade 12 cuts the bridge steel, its proximity to the steel causes drain pipe 26 and nozzle 27 to move closer. At this point, the operator uses water pump 18 to pump the cutting fluid out through outlet pipe 20.The fluid is discharged through the telescopic hose 21 into the diversion pipe 22 and the rubber hose 25, then into the drain pipe 26 and sprayed out through the nozzle 27.

This facilitates cooling of the bridge steel during cutting and lubricates both the cutting blade 12 and the bridge steel, improving the cutting effect. Simultaneously, the use of cutting fluid reduces friction and tool wear caused by high temperatures, maintains the tool's hardness and cutting performance, and prevents the bridge steel from expanding due to heat and contracting after cooling, thus avoiding dimensional inaccuracies.

Then, he moves the adjusting column 70 to move the stabilizing frame 71 and the fastening column 32 to adjust the position of the fastening column 32 and the rubber block 31 so that the rubber block 31 is on the top surface of the bridge steel. Then, the worker rotates the fastening column 32 to rotate the rubber block 31, so that the rubber block 31 is close to the top surface of the bridge steel, and tightens the fastening column 32, which facilitates the clamping of the bridge steel.

[0049] Working principle: Please refer to Figures 1-12As shown, when the worker cuts the bridge steel using the cutting blade 12, the bridge steel is placed on the top surface of the cutting table 1. The worker then uses the servo motor 15, whose drive shaft rotates to rotate the main pulley 16. The rotation of the main pulley 16 then drives the driven pulley 14 via the V-belt 17. The driven pulley 14 then drives the transmission column 13, the stabilizing column 10, and the cutting blade 12 to rotate. The cutting blade 12 is then brought close to the bridge steel to facilitate cutting. Before cutting the bridge steel, cutting fluid is added to the water tank 2. When the cutting blade 12 cuts the bridge steel, the cutting blade 12 moves closer to the bridge steel, thus driving the transmission column 13, the stabilizing column 10, and the cutting blade 12 to rotate. With the drain pipe 26 and nozzle 27 close to the bridge steel, the operator uses a water pump 18 to draw cutting fluid through the outlet pipe 20 and discharge it through the telescopic hose 21 into the diversion pipe 22 and the rubber hose 25. The fluid then enters the drain pipe 26 and is sprayed out through the nozzle 27. The cutting fluid is then sprayed onto the surface of the bridge steel, working in conjunction with the cutting blade 12 to cut the steel. This facilitates cooling the bridge steel during cutting and lubricates the cutting blade 12 and the bridge steel, improving the cutting effect. Simultaneously, the cutting fluid reduces friction and tool wear caused by high temperatures, maintains the tool's hardness and cutting performance, and prevents the bridge steel from expanding due to heat and contracting after cooling, which could lead to inaccurate dimensions.

[0050] By moving the limiting ring 34 upwards, the operator moves the locking block 38 out of the locking housing 39. At this time, the locking post 36 also disengages from the locking groove 37, thus releasing the restriction on the drain pipe 26 and the adjusting ring 35. Subsequently, the operator can rotate the drain pipe 26 to rotate the nozzle 27 and the adjusting ring 35. After the nozzle 27 has rotated, the operator moves the limiting ring 34 downwards to move the locking block 38 back into the locking housing 39, allowing the locking post 36 to engage with the locking groove 37. This restricts the drain pipe 26 and the adjusting ring 35, making it easier to rotate and adjust the spray angle of the nozzle 27.

[0051] Through the transmission rod 42, the operator rotates the transmission rod 42 to drive the two first transmission wheels 43 to rotate. The two first transmission wheels 43 then drive the two second transmission wheels 46 to rotate through the two first belts 48. When the second transmission wheels 46 rotate, they drive the movable column 45 and the main synchronous wheel 47 to rotate. The main synchronous wheel 47 then drives the secondary synchronous wheel 52 and the rotating column 51 to rotate through the synchronous belt 49. At this time, the synchronous belts 49 on both sides inside the cutting table 1 will move. When the upper end of the synchronous belt 49 moves, it will drive the sliding block 53 and the moving table 3 to move, so that the cutting blade 12 can slowly approach the bridge steel, thereby facilitating the cutting of the bridge steel by moving the cutting blade 12.

[0052] By using the bolt 58, the operator can move the bolt 58 out of the fixing hole 57 and the first threaded groove 59, and then move the mounting shell 5 upward to move the cutting blade 12, thereby raising the position of the cutting blade 12. Then, the bolt 58 is inserted through the fixing hole 57 into the first threaded groove 59 and tightened, which facilitates the adjustment of the cutting height of the cutting blade 12.

[0053] By rotating the fixed column 24, the operator can loosen it from the surface of the stabilizing column 10, thereby moving the fixed column 24 away from one end of the stabilizing column 10. Then, the operator can rotate the movable frame 7 around the connecting column 74 and then move the movable frame 7 away from one side of the cutting blade 12. At this time, the operator can move the cutting blade 12 to remove it from the surface of the stabilizing column 10, which makes it easier to disassemble and replace the cutting blade 12.

[0054] With the water storage tank 63 in place, after the cutting fluid is sprayed onto the bridge steel being cut, the cutting fluid will flow back into the water storage tank 2 through the water outlet 64 and the circulation pipe 62, thus facilitating the recycling of the cutting fluid.
