Furthermore, it is difficult to guarantee that every accurate cut will completely sever the target area. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a laser cutting device for steel in bridge construction, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a steel laser cutting equipment for bridge construction, comprising a long frame, an equidistant device for equidistant cutting of steel, the equidistant device further comprising; A laser cutting machine, wherein the laser cutting machine is mounted on top of a long frame, the long frame is equipped with a conveyor belt inside, and a finished product box is fixedly installed at the bottom of the long frame; A cylinder is rotatably installed inside a conveyor belt. A reciprocating spiral groove is formed on the circumference of the cylinder. A rounded corner plate is slidably installed on the reciprocating spiral groove of the cylinder. An elastic telescopic pressure plate is fixedly installed at the bottom of the rounded corner plate. The elastic telescopic pressure plate is used to fix the steel plate at equal intervals. A transmission column is rotatably mounted on the front of the long frame. The free end of an elastic telescopic rod is fixedly mounted on the circumference of the transmission column. The free end of the elastic telescopic rod has a slot. The fixed end of the elastic telescopic rod is fixedly mounted with a ring frame. The ring frame is used to fix the steel plate to prevent it from tilting. When the conveyor belt moves, it will drive the column to rotate. When the column rotates, it will drive the rounded corner plate to move up and down on the column. When the rounded corner plate moves, it will drive the elastic telescopic pressure plate to move.

[0007] According to the above technical solution, the equidistant device further includes a square plate, a telescopic column, and an elastic telescopic clamping plate. The square plate is fixedly installed at the bottom of the rounded corner plate. The fixed end of the telescopic column is rotatably installed on the side of the square plate near the ring frame. The free end of the telescopic column is fixedly installed with the transmission column. The elastic telescopic clamping plate is fixedly installed at the fixed end of the elastic telescopic rod. When the elastic telescopic clamping plate comes into contact with the steel plate, it will squeeze the steel plate and stop the steel plate from moving. At the same time, since the elastic telescopic clamping plate is elastically expandable and contractible, it can reduce the impact of steel plate deformation.

[0008] According to the above technical solution, the elastic telescopic pressure plate is in contact with the steel, the ring frame is in contact with the steel, and the slot at the free end of the elastic telescopic rod is in contact with the elastic telescopic pressure plate. The bottom of the long frame is equipped with an auxiliary device for automatic retrieval and a retrieval device for easy removal by staff. If the steel plate is not cut completely, the ring frame will be limited. When the ring frame is limited, the rounded corner plate will also be limited. When the rounded corner plate is limited, the steel plate will also be limited, and the cutting will continue.

[0009] According to the above technical solution, the auxiliary device includes a round block, a flat ring, a gear, a reciprocating screw, a sliding block, an elastic telescopic push block, a bottom block, a telescopic sliding plate, and an irregular rod. The flat ring is fixedly installed on the side of the square plate near the long frame. The gear is rotatably installed on the front of the finished product box. The round block is rotatably installed on the front of the gear. The irregular rod is fixedly installed on the bottom of the inner wall of the finished product box. The reciprocating screw is fixedly installed on the side of the gear near the irregular rod. The sliding block is threaded onto the circumferential surface of the reciprocating screw. The fixed end of the elastic telescopic push block is fixedly installed on the side of the sliding block near the irregular rod. The free end of the elastic telescopic push block slides through the irregular rod. The bottom block is fixedly installed on the front of the finished product box. The fixed end of the telescopic sliding plate is fixedly installed on the top of the bottom block. The free end of the elastic telescopic push block is slidably connected to the telescopic sliding plate. When the round block slides inside the flat ring, it drives the gear to rotate. When the gear rotates, it drives the reciprocating screw to rotate. When the reciprocating screw rotates, it drives the sliding block to move on the reciprocating screw.

[0010] According to the above technical solution, the auxiliary device also includes a rack and an inclined push plate. The inclined push plate is slidably installed on the inner wall of the finished product box, and the rack is rotatably installed on the front side of the inclined push plate. A protrusion is provided on the top of the end of the rack near the inclined push plate. When the elastic telescopic push block moves, it will straighten the steel plate so that the steel plate can pass through the irregular rod. At the same time, when the steel plate contacts the free end of the elastic telescopic push block, it will cause the elastic telescopic push block to retract downward.

[0011] According to the above technical solution, the gear meshes with the rack, the inclined push plate contacts the elastic telescopic push block, a spring is provided between the rack and the inclined push plate, and a second spring is provided between the inclined push plate and the finished product box. When the gear rotates, it will drive the rack to move. When the rack moves, it will drive the inclined push plate to move. When the gear continues to rotate, it will press the protrusion on the rack downward.

[0012] According to the above technical solution, the picking device includes a rectangular block, a square column, a semi-circular body, an elastic telescopic pressure block, a long plate, a connecting plate, and an insert plate. The rectangular block is fixedly installed at the bottom of the finished product box. The fixed end of the elastic telescopic pressure block is fixedly installed inside the bottom of the rectangular block. The square column is fixedly installed on the left side of the rectangular block. The semi-circular body is fixedly installed on the side of the square column near the elastic telescopic pressure block. The long plate is fixedly installed at the free end of the elastic telescopic pressure block. One end of the connecting plate is fixedly installed at the top of the long plate. The insert plate is fixedly installed at the other end of the connecting plate. When the long plate moves, it will drive the free end of the elastic telescopic pressure block inside the rectangular block to move downward. When the elastic telescopic pressure block moves downward, the steel plate on the elastic telescopic pressure block will slide off.

[0013] According to the above technical solution, the inclined push plate is in contact with the insert plate, and the long plate is in contact with the semicircular body. When the semicircular body is in contact with the long plate, the long plate will vibrate. At the same time, when the long plate vibrates, the steel plate on the free end of the elastic telescopic pressure block will be shaken off.

[0014] This invention provides a laser cutting device for steel in bridge construction. It has the following advantages: (1) This invention can meet the cutting needs of steel plates of different specifications in bridge construction by simply adjusting the elastic telescopic plate, reducing equipment adaptation costs and improving applicability to diverse construction scenarios. If the steel plate is not cut completely or not cut, the uncut steel plate will limit the ring frame, thereby restricting the movement of the rounded corner plate, and finally keeping the steel plate stationary and continuing to cut, avoiding the uncut steel plate from entering the next process with the conveyor belt, reducing steel waste, rework or equipment jamming losses caused by substandard cutting.

[0015] (2) In this invention, when the gear drives the rack to move, it will simultaneously drive the inclined push plate to move, pushing the steel plate that falls into the finished product box to the designated area, preventing the subsequent cut steel plates from falling and causing blockage due to disordered stacking. When the elastic telescopic push block moves with the sliding block, it will actively straighten the offset steel plate, ensuring that the steel plate can accurately pass through the irregular rod, avoiding the deviation of the transportation path caused by the skewed posture, reducing the situation where the steel plate gets stuck between the elastic telescopic push block and the finished product box, and ensuring the continuity of the steel plate transportation process after cutting.

[0016] (3) When the insert plate moves upward, it can guide and block the falling steel plate to prevent it from being inserted obliquely to the bottom, ensuring that the inclined push plate can smoothly push the steel plate in the finished product box, ensuring the coordinated operation of the auxiliary device and the picking device, avoiding equipment jamming failure. The long plate drives the free end of the elastic telescopic pressure block to move downward, so that the cut steel plate placed on the pressure block automatically slides down. There is no need for manual removal by hand when the steel plate is just cut and the temperature is high, avoiding burns to the operator. At the same time, it also reduces the labor intensity of manual material picking and reduces manual intervention. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-7 One embodiment of the present invention is: a steel laser cutting equipment for bridge construction, including a long frame 1, an equidistant device for equidistant cutting of steel, the equidistant device further comprising; Laser cutting machine 2 is set on top of long frame 1. A conveyor belt 3 is set inside long frame 1. Finished product box 4 is fixedly installed at the bottom of long frame 1. A cylinder 401 is rotatably installed inside the conveyor belt 3. A reciprocating spiral groove is provided on the circumferential surface of the cylinder 401. A rounded corner plate 402 is slidably installed on the reciprocating spiral groove of the cylinder 401. An elastic telescopic pressure plate 403 is fixedly installed at the bottom of the rounded corner plate 402. The elastic telescopic pressure plate 403 is used to fix the steel plate at equal intervals. The transmission column 406 is rotatably mounted on the front of the long frame 1. The free end of the elastic telescopic rod 407 is fixedly mounted on the circumferential surface of the transmission column 406. The free end of the elastic telescopic rod 407 has a slot. The fixed end of the elastic telescopic rod 407 is fixedly mounted with a ring frame 408. The ring frame 408 is used to fix the steel plate to prevent it from tilting, thereby interlocking and restricting the movement of the rounded corner plate 402, ultimately keeping the steel plate stationary and continuing to cut. This prevents uncut steel plates from entering the next process with the conveyor belt 3, reducing steel waste, rework, or equipment jamming losses caused by substandard cutting.

[0021] The equidistant device also includes a square plate 404, a telescopic column 405, and an elastic telescopic clamping plate 409. The square plate 404 is fixedly installed at the bottom of the rounded corner plate 402. The fixed end of the telescopic column 405 is rotatably installed on the side of the square plate 404 near the ring frame 408. The free end of the telescopic column 405 is fixedly installed with the transmission column 406. The elastic telescopic clamping plate 409 is fixedly installed at the fixed end of the elastic telescopic rod 407. When the elastic telescopic pressure plate 403 contacts the steel plate, it will squeeze the steel plate and stop the steel plate from moving. At the same time, since the elastic telescopic pressure plate 403 is elastically telescopic, it can reduce the impact of steel plate deformation.

[0022] The elastic telescopic pressure plate 403 is in contact with the steel, the ring frame 408 is in contact with the steel, and the slot at the free end of the elastic telescopic rod 407 is in contact with the elastic telescopic clamping plate 409. When the steel plate is not completely cut, the ring frame 408 will be limited. When the ring frame 408 is limited, the rounded corner plate 402 will also be limited. When the rounded corner plate 402 is limited, the steel plate will also be limited, and the cutting will continue.

[0023] In this embodiment, during operation: the elastic telescopic plate 409 on the elastic telescopic rod 407 is adjusted according to the required length of the steel plate to ensure that the length of the elastic telescopic rod 407 meets the standard. The steel plate is placed on the internal conveyor belt 3 of the long frame 1, the conveyor belt 3 is started, and the laser cutting machine 2 is started. When the conveyor belt 3 starts, it will move the steel plate. When the conveyor belt 3 moves, it will rotate the cylinder 401. When the cylinder 401 rotates, it will move the rounded corner plate 402 up and down on the cylinder 401. When the rounded corner plate 402 moves, it will move the elastic telescopic pressure plate 403. When the elastic telescopic pressure plate 403 moves, it will contact the steel plate. When the elastic telescopic pressure plate 403 contacts the steel plate, it will squeeze the steel plate and stop the steel plate from moving. Meanwhile, since the elastic telescopic pressure plate 403 is elastically telescopic, it can reduce the impact of steel plate deformation. When the rounded corner plate 402 moves, it will drive the square plate 404 to move. When the square plate 404 moves, it will drive the telescopic column 405 to rotate on the transmission column 406. When the telescopic column 405 rotates, it will drive the transmission column 406 to rotate. When the transmission column 406 rotates, it will drive the elastic telescopic rod 407 to rotate. When the elastic telescopic rod 407 rotates, it drives the ring frame 408 to rotate. When the ring frame 408 rotates, it flips upward. When the ring frame 408 flips upward, the elastic telescopic pressure plate 403 has not completely limited the steel plate, so part of the steel plate will enter the interior of the ring frame 408. When the steel plate is not completely cut, the ring frame 408 will be limited. When the ring frame 408 is limited, the rounded corner plate 402 will also be limited. When the rounded corner plate 402 is limited, the steel plate will also be limited, and the cutting will continue to prevent the steel plate from being cut and causing losses in the next step.

[0024] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, the bottom of the long frame 1 is provided with an auxiliary device for automatic retrieval and a retrieval device for easy removal by staff. The auxiliary device includes a round block 501, a flat ring 502, a gear 503, a reciprocating screw 504, a sliding block 505, an elastic telescopic push block 506, a bottom block 507, a telescopic sliding plate 508, and an irregular rod 509. The flat ring 502 is fixedly installed on the side of the square plate 404 near the long frame 1. The gear 503 is rotatably installed on the front of the finished product box 4. The round block 501 is rotatably installed on the front of the gear 503. The irregular rod 509 is fixedly installed on the bottom of the inner wall of the finished product box 4. The reciprocating screw 504 is fixedly installed on the gear 503 near the irregular rod 509. On one side, the sliding block 505 is threaded onto the circumferential surface of the reciprocating screw 504. The fixed end of the elastic telescopic push block 506 is fixedly installed on the side of the sliding block 505 near the irregular rod 509. The free end of the elastic telescopic push block 506 slides through the irregular rod 509. The bottom block 507 is fixedly installed on the front of the finished product box 4. The fixed end of the telescopic slide plate 508 is fixedly installed on the top of the bottom block 507. The free end of the elastic telescopic push block 506 is slidably connected to the telescopic slide plate 508, actively straightening the offset steel plate and ensuring that the steel plate can accurately pass through the irregular rod 509. This avoids deviation of the transportation path caused by the skewed posture, reduces the situation where the steel plate gets stuck between the elastic telescopic push block 506 and the finished product box 4, and ensures the continuity of the steel plate transportation process after cutting.

[0025] The auxiliary device also includes a rack 510 and an inclined push plate 511. The inclined push plate 511 is slidably installed on the inner wall of the finished product box 4. The rack 510 is rotatably installed on the front side of the inclined push plate 511. A protrusion is provided on the top of the end of the rack 510 near the inclined push plate 511. When the elastic telescopic push block 506 moves, it will straighten the steel plate so that the steel plate can pass through the irregular rod 509. At the same time, when the steel plate contacts the free end of the elastic telescopic push block 506, it will cause the elastic telescopic push block 506 to retract downward.

[0026] Gear 503 meshes with rack 510, inclined push plate 511 contacts elastic telescopic push block 506, a spring is provided between rack 510 and inclined push plate 511, and a second spring is provided between inclined push plate 511 and finished product box 4. When gear 503 rotates, it will drive rack 510 to move. When rack 510 moves, it will drive inclined push plate 511 to move. When gear 503 continues to rotate, it will press the protrusion on rack 510 downward.

[0027] The retrieving device includes a rectangular block 601, a square column 602, a semi-circular body 603, an elastic telescopic pressure block 604, a long plate 605, a connecting plate 606, and an insert plate 607. The rectangular block 601 is fixedly installed at the bottom of the finished product box 4. The fixed end of the elastic telescopic pressure block 604 is fixedly installed at the bottom inside the rectangular block 601. The square column 602 is fixedly installed on the left side of the rectangular block 601. The semi-circular body 603 is fixedly installed on the side of the square column 602 near the elastic telescopic pressure block 604. The long plate 605 is fixedly installed at the free end of the elastic telescopic pressure block 604. One end of the connecting plate 606 is fixedly installed at the top of the long plate 605. The insert plate 607 is fixedly installed at the other end of the connecting plate 606. After cutting, the steel plate placed on the pressure block automatically slides down, eliminating the need for manual removal by hand when the steel plate is freshly cut and at a high temperature. This avoids burns to the operator and reduces the labor intensity of manual material handling, minimizing manual intervention.

[0028] The inclined push plate 511 contacts the insert plate 607, and the long plate 605 contacts the semi-circular body 603. When the semi-circular body 603 contacts the long plate 605, the long plate 605 will vibrate. At the same time, when the long plate 605 vibrates, the steel plate on the free end of the elastic telescopic pressure block 604 will be shaken off.

[0029] In this embodiment, when the square plate 404 moves, it will drive the flat ring 502 to move. When the flat ring 502 moves, it will drive the round block 501 to slide inside the flat ring 502. When the round block 501 slides inside the flat ring 502, it will drive the gear 503 to rotate. When the gear 503 rotates, it will drive the reciprocating screw 504 to rotate. When the reciprocating screw 504 rotates, it will drive the sliding block 505 to move on the reciprocating screw 504. When the sliding block 505 moves, it will drive the elastic telescopic push block 506 to move. When the elastic telescopic push block 506 moves, it will straighten the steel plate so that the steel plate can pass through the irregular rod 509. At the same time, when the steel plate contacts the free end of the elastic telescopic push block 506, it will cause the elastic telescopic push block 506 to retract downward. Meanwhile, the telescopic slide plate 508 on the outer bottom block 507 will push the steel plate on the elastic telescopic push block 506 to avoid getting stuck between the elastic telescopic push block 506 and the finished box 4. When gear 503 rotates, it drives rack 510 to move. When rack 510 moves, it drives inclined push plate 511 to move. When gear 503 continues to rotate, it pushes the protrusion on rack 510 downward. When the protrusion moves downward, it flips rack 510 downward, causing rack 510 to disengage from gear 503. Inclined push plate 511 returns to its original position under the action of spring number two. At the same time, rack 510 slowly returns to its original position under the action of spring. When inclined push plate 511 moves, it can move the steel plate that falls on finished product box 4 to prevent subsequent steel plates from falling and causing accumulation and blockage.

[0030] When the inclined push plate 511 moves, it will squeeze the insert plate 607. When the insert plate 607 is squeezed, the connecting plate 606 will move downward. When the connecting plate 606 moves, it will drive the long plate 605 to move. When the long plate 605 moves, it will drive the free end of the elastic telescopic pressure block 604 inside the rectangular block 601 to move downward. When the elastic telescopic pressure block 604 moves downward, the steel plate on the elastic telescopic pressure block 604 will slide off, reducing the need for manual removal when the steel plate temperature is too high. At the same time, when the long plate 605 moves downward, it will contact the semicircular body 603 on the square column 602. When the semicircular body 603 contacts the long plate 605, the long plate 605 will vibrate. At the same time, when the long plate 605 vibrates, it will shake off the steel plate on the free end of the elastic telescopic pressure block 604, and when the insert plate 607 moves upward, it can prevent the steel plate from being inserted obliquely into the bottom of the finished box 4, causing inconvenience to push the inclined push plate 511.

[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
