Description

Technical Field

[0001] This invention relates to the field of cutting and processing technology, specifically to a cutting and processing mechanism and operating method for Bailey bridge steel components. Background Technology

[0002] The Bailey Bridge was invented in 1938 by British engineer Donald West Bailey. This type of bridge is composed of lightweight, standardized truss units made of high-strength steel, as well as crossbeams, longitudinal beams, bridge decks, abutments, and connectors. It can be quickly assembled on-site using specialized installation equipment to form a truss beam bridge suitable for various spans and loads.

[0003] In the prior art, patent number CN208825688U, entitled "A Steel Pipe Cutting Machine," belongs to the field of steel pipe cutting technology. The steel pipe cutting machine includes: a cutting table, a clamp connected to the cutting table, a first elastic component and a second elastic component connected to the clamp, a first support rod and a second support rod connected to the cutting table, a first horizontal plate connected to the first support rod and the second support rod, a first vertical rod connected to the first horizontal plate, a vertical rod stop plate connected to the first vertical rod, a first motor, and a third elastic component, and a cutting disc and a switch connected to the first motor. This application uses a clamp to fix the steel pipe; the gap between the clamps can be adjusted through the first groove and the first elastic component, and the second groove and the second elastic component; the third elastic component automatically resets the motor and the first vertical rod after operation; the vertical rod stop plate prevents the third elastic component from popping out, and the foot pedal on the vertical rod stop plate blocks sparks generated during cutting, improving safety.

[0004] However, when cutting existing Bailey bridge steel components, if the steel component is long, it needs to be placed on the cutting table. After cutting, both ends of the steel component will fall off, causing the steel component to hit the ground, which is quite dangerous. Summary of the Invention

[0005] The purpose of this invention is to provide a cutting and processing mechanism and operating method for Bailey bridge steel components to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a Bailey bridge steel component cutting and processing mechanism, comprising:

[0011] Preferably, the end of the arc-shaped plate is fixed with a second extension rod, so that after the arc-shaped plate rises, it can be supported in the second support groove on the surface of the swing frame, and when the swing frame swings around the pivot, the second extension rod at the end of the arc-shaped plate can be supported in the first support groove on the surface of the swing frame.

[0012] Preferably, a U-shaped plate is fixed to the surface of the L-shaped plate, and an elastic band is provided on the surface of the U-shaped plate. The elastic band is elastic and is located at the bottom of the first piston rod. After the U-shaped plate and the elastic band rise with the L-shaped plate, the elastic band supports the bottom of the first piston rod.

[0013] Preferably, the surface of the swing frame is provided with a second sliding groove, and a transverse plate is inserted into the second sliding groove. The transverse plate can move in the second sliding groove. A first extension rod is fixed to the bottom of the transverse plate. A telescopic rod is inserted into the end of the first extension rod.

[0016] A method for operating a Bailey bridge steel component cutting and processing mechanism includes the following steps:

[0017] Step 1: Adjustment. The end of the swing frame swings around the pivot, causing the two sets of swing frames to move away from each other. The second extension rod is held in the first support groove and supported on the surface of the swing frame to stabilize it. The steel frame is placed on the surface of the cutting table. The first piston rod is driven by the first cylinder to move. The first piston rod drives the support frame to move. The support frame moves in the first slide groove. Since the cutting table and the support frame are supported on the surface of the cutting table, the first roller is in contact with the steel frame. The rotation of the first roller allows the support frame to move at the bottom of the steel frame and increases the area of ​​support for the bottom of the steel frame.

[0018] Step Two: Holding the oscillating frames together. The fixing plates at the ends of the two oscillating frames are fixed by screws, so that the two oscillating frames surround the outside of the steel frame. The transverse plate can move in the second sliding groove on the surface of the oscillating frame, so that the cutting position is between the two ends of the transverse plate. Tighten the screw, and the screw will drive the holding plate to move down. Adjust the position of the bottom of the holding plate. After the two oscillating frames are close together, the telescopic rod can extend from the first extension rod, so that the magnets on the surfaces of the two adsorption plates can be attracted together. The handle can be used to drive the two transverse plates to adjust their positions. The second piston rod is driven to move down by the second cylinder. The second piston rod drives the lifting block to move down in the lifting groove. The lifting block drives the oscillating frame to move down, so that the holding plate holds the surface of the steel frame. When the steel frame is cut, the holding plate and the support of the second roller prevent the steel frame from falling to the ground.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] This invention proposes two sets of swing frames brought close together, with the fixing plates at the ends of the two sets of swing frames fixed by screws, so that the two sets of swing frames surround the outside of the steel frame. The transverse plate can move in the second sliding groove on the surface of the swing frame, so that the cutting position is located between the two ends of the transverse plate. Tightening the screw causes the screw to move the top holding plate down, adjusting the position of the bottom of the top holding plate. After the two sets of swing frames are brought close together, the telescopic rod can extend from the first extension rod, so that the magnets on the surfaces of the two sets of adsorption plates are attracted together. The position of the two sets of transverse plates can be adjusted by the handle. The second piston rod is driven down by the second cylinder, and the second piston rod drives the lifting block down in the lifting groove. The lifting block drives the swing frame down, so that the top holding plate holds the surface of the steel frame. When the steel frame is cut, the steel frame will not fall to the ground due to the support of the top holding plate and the support of the second roller. Attached Figure Description

The first piston rod 13 is driven by the first cylinder 14 to move. The first piston rod 13 drives the support frame 9 to move. The support frame 9 moves in the first slide groove 10. Since the cutting table 1 and the support frame 9 are supported on the surface of the cutting table 1, the first roller 11 is in contact with the steel frame 2. The rotation of the first roller 11 allows the support frame 9 to move at the bottom of the steel frame 2.

[0035] The surface of the cutting table 1 is provided with a lifting groove 28, and a lifting block 21 is inserted into the lifting groove 28.

The telescopic rod 32 can move within the first extension rod 31. An extension rod 30 telescopically moves within the extension rod 32. An adsorption plate 31 is fixed to the other end of the extension rod 32. Magnets 33 are fixed to the surface of the adsorption plate 31, allowing the magnets 33 on the surfaces of the two sets of adsorption plates 31 to adhere together. A fixing plate 4 is fixed to one end of the swing frame 3 that is close to the other. The two sets of fixing plates 4 can be fixed together by screws, and when the two sets of swing frames 3 are close to each other, the two sets of fixing plates 4 are close together. A handle 6 is fixed to the surface of the transverse plate 5, and the transverse plate 5 moves with the handle 6. Top holding plates 8 are inserted into the bottom of both ends of the transverse plate 5. The top plate 8 can move up and down inside the transverse plate 5. A screw 7 is screwed onto the surface of the transverse plate 5. The end of the screw 7 abuts against the surface of the top plate 8. After the screw 7 moves, it can push the top plate 8 to move. The transverse plate 5 can move in the second slide groove 34 on the surface of the swing frame 3, so that the cutting position is located between the two ends of the transverse plate 5. Tighten the screw 7, and the screw 7 drives the top plate 8 to move down, adjusting the position of the bottom of the top plate 8. After the two sets of swing frames 3 approach each other, the telescopic rod 32 can extend from the first extension rod 30.

[0036] An extension plate 25 is fixed to the surface of the cutting table 1. A third cylinder 26 is fixed to the surface of the extension plate 25. A third piston rod 24 is provided at the end of the third cylinder 26. The third cylinder 26 can drive the third piston rod 24 to move up and down. An arc-shaped plate 27 is fixed to the other end of the third piston rod 24. The arc-shaped plate 27 moves up and down with the third piston rod 24. An L-shaped plate 15 is fixed to the surface of the third piston rod 24. The L-shaped plate 15 is located on both sides of the third piston rod 24. The L-shaped plate 15 moves up and down with the third piston rod 24. A second extension rod 35 is fixed to the end of the arc-shaped plate 27. After the arc-shaped plate 27 rises, it can rest in the second support groove 29 on the surface of the swing frame 3. When the swing frame 3 swings around the rotating shaft 20, the second extension rod 25 at the end of the arc-shaped plate 27... The second extension rod 35 can be held in the first support groove 18 on the surface of the swing frame 3. A U-shaped plate 16 is fixed on the surface of the L-shaped plate 15. An elastic band 17 is provided on the surface of the U-shaped plate 16. The elastic band 17 is elastic and is located at the bottom of the first piston rod 13. After the U-shaped plate 16 and the elastic band 17 rise with the L-shaped plate 15, the elastic band 17 holds the bottom of the first piston rod 13. During the rise of the third piston rod 24, the L-shaped plate 15 is driven to rise. The L-shaped plate 15 drives the U-shaped plate 16 and the elastic band 17 to rise. The elastic band 17 holds the bottom of the first piston rod 13, keeping the first piston rod 13 stable. The elastic band 17 is elastic. After the L-shaped plate 15 continues to rise, the elastic band 17 is stretched and still holds the surface of the first piston rod 13.

[0037] The end of the swing frame 3 swings around the rotating shaft 20, causing the two sets of swing frames 3 to move away from each other. The second extension rod 35 rests in the first support groove 18, supporting the surface of the swing frame 3 and stabilizing it. The steel frame 2 is placed on the surface of the cutting table 1. The first piston rod 13 is moved by the first cylinder 14, which in turn moves the support frame 9. The support frame 9 moves in the first slide groove 10. Since the cutting table 1 and the support frame 9 are supported on the surface of the cutting table 1, the first roller 11 contacts the steel frame 2. The rotation of the first roller 11 causes the support frame 2 to move. The frame 9 can move at the bottom of the steel frame 2, increasing the supporting area at the bottom of the steel frame 2. The two sets of swing frames 3 are brought closer together, and the fixing plates 4 at the ends of the two sets of swing frames 3 are fixed by screws, so that the two sets of swing frames 3 surround the outside of the steel frame 2. The transverse plate 5 can move in the second sliding groove 34 on the surface of the swing frame 3, so that the cutting position is located between the two ends of the transverse plate 5. Tightening the screw 7 causes the top holding plate 8 to move downwards, adjusting the position of the bottom of the top holding plate 8. After the two sets of swing frames 3 are brought closer together, the telescopic rod 32 can extend from the first extension rod 30. This causes the magnets 33 on the surfaces of the two sets of adsorption plates 31 to adhere together. The handle 6 allows for position adjustment of the two sets of transverse plates 5. The second cylinder 23 drives the second piston rod 22 downwards, which in turn moves the lifting block 21 downwards in the lifting groove 28. The lifting block 21 then moves the swing frame 3 downwards, causing the top holding plate 8 to press against the surface of the steel frame 2. When the steel frame 2 is cut, the support of the top holding plate 8 and the support frame 9 prevent the steel frame 2 from crashing to the ground. Furthermore, the third cylinder 26 drives the third piston rod 24 upwards. Rod 24 drives the arc plate 27 and the second extension rod 35 to rise. The arc plate 27 is supported in the second support groove 29, which can maintain the stability of the swing frame 3 and facilitate the fixation of the two sets of swing frames 3 by screws. During the rise of the third piston rod 24, the L-shaped plate 15 is driven to rise. The L-shaped plate 15 drives the U-shaped plate 16 and the elastic band 17 to rise. The elastic band 17 is held against the bottom of the first piston rod 13 to maintain the stability of the first piston rod 13. The elastic band 17 is elastic. After the L-shaped plate 15 continues to rise, the elastic band 17 is stretched and still holds against the surface of the first piston rod 13.

The end of the swing frame (3) swings around the pivot (20) so that the two sets of swing frames (3) move away from each other. The second extension rod (35) is held in the first support groove (18) and supported on the surface of the swing frame (3) to stabilize the swing frame (3). The steel frame (2) is placed on the surface of the cutting table (1). The first piston rod (13) is driven to move by the first cylinder (14). The first piston rod (13) drives the support frame (9) to move. The support frame (9) moves in the first slide groove (10). Since the cutting table (1) and the support frame (9) are supported on the surface of the cutting table (1), the first roller (11) contacts the steel frame (2). The rotation of the first roller (11) allows the support frame (9) to move at the bottom of the steel frame (2) and increases the area supported at the bottom of the steel frame (2). Step 2: Hold the two sets of swing frames (3) close together. Fix the end plates (4) of the two sets of swing frames (3) with screws, so that the two sets of swing frames (3) surround the outside of the steel frame (2). The transverse plate (5) can move in the second groove (34) on the surface of the swing frame (3), so that the cutting position is between the two ends of the transverse plate (5). Tighten the screw (7), and the screw (7) will drive the top holding plate (8) down, adjusting the position of the bottom of the top holding plate (8). After the two sets of swing frames (3) are close together, the telescopic rod (32) can extend from the first extension rod (30), allowing... The magnets (33) on the surfaces of the two sets of adsorption plates (31) are attracted together. The handle (6) can drive the two sets of transverse plates (5) to adjust their positions. The second piston rod (22) is driven to move down by the second cylinder (23). The second piston rod (22) drives the lifting block (21) to move down in the lifting groove (28). The lifting block (21) drives the swing frame (3) to move down, so that the top plate (8) is held against the surface of the steel frame (2). When the steel frame (2) is cut, the steel frame (2) will not fall to the ground due to the support of the top plate (8) and the second roller (12).
