[0004] With respect to the above-mentioned related technologies, the inventors believe that although the above-mentioned circular saw can improve the sawing efficiency and clean up the debris, when the above-mentioned circular saw is sawing the steel grating, the steel grating will shake due to the sawing, thereby reducing the sawing accuracy of the steel grating. Summary of the invention

[0005] In order to improve the stability of the steel grating during sawing and improve the sawing accuracy of the steel grating, the present application provides a mobile circular saw.

[0006] The mobile circular saw provided in the present application adopts the following technical solution:

[0007] A mobile circular saw comprises a workbench, on which are provided two conveyor belts close to each other, a support frame fixedly arranged on the workbench and placed above the conveyor belts, a sawing assembly slidably connected to the support frame, the sawing assembly being placed between the two conveyor belts, the sliding direction of the sawing assembly being perpendicular to the transport direction of the conveyor belts, two longitudinal clamping assemblies placed above the conveyor belts being fixedly arranged on the support frame, the two longitudinal clamping assemblies being distributed along the transport direction of the conveyor belts and being respectively placed on both sides of the sawing assembly, the longitudinal clamping assembly comprising a longitudinal cylinder, the longitudinal cylinder being fixedly connected to the support frame, and the output shaft of the longitudinal cylinder being fixedly provided with a longitudinal clamping seat placed above the conveyor belts.

[0008] By adopting the above technical scheme, the workbench plays the role of supporting the conveyor belt. When the operator places the steel grating on the conveyor belt, the conveyor belt plays the role of transporting the steel grating. The support frame plays the role of supporting the sawing assembly and the longitudinal clamping assembly. When the steel grating is transported to a suitable position, the longitudinal cylinder drives the longitudinal clamping seat to move. The steel grating is clamped through the cooperation between the longitudinal clamping seat and the conveyor belt. At this time, the steel grating is sawed by the movement of the sawing assembly. The steel grating is clamped by the longitudinal clamping assembly, thereby improving the stability of the steel grating during sawing, which has the effect of improving the sawing accuracy of the steel grating.

[0009] Optionally, the sawing assembly includes a sawing frame, which is slidably connected to a supporting frame, a circular saw blade placed between two conveyor belts is rotatably connected to the bottom of the sawing frame, a connecting shaft is fixedly provided on one side of the circular saw blade, an adjusting plate is provided on the sawing frame, one end of the adjusting plate is hinged to the sawing frame, an adjusting screw placed on the other end of the adjusting plate is hinged on the sawing frame, the adjusting screw passes through the adjusting plate, two adjusting nuts placed on both sides of the adjusting plate are threadedly connected to the adjusting screw, a driving motor is fixed on the adjusting plate, and the output shaft of the driving motor is connected to the connecting shaft through a belt.

[0010] By adopting the above technical scheme, the sawing frame plays the role of supporting the circular saw blade. The operator starts the driving motor, and the output shaft of the driving motor rotates, which in turn drives the connecting shaft to rotate through the belt, thereby realizing the rotation of the circular saw blade. The steel grating is sawed by the rotation of the circular saw blade. When the belt is loose between the connecting shaft and the output shaft of the driving motor, the operator rotates the adjusting plate, and adjusts the tightness of the belt by adjusting the inclination of the adjusting plate on the sawing frame, thereby facilitating the operator to replace the belt and adjust the tightness of the belt. When the inclination of the adjusting plate is adjusted, the adjusting screw and the adjusting nut cooperate with each other, and the adjusting nut is turned to limit the position of the adjusting plate. The adjusting plate is clamped by the two adjusting nuts, thereby improving the stability of the adjusting plate.

[0011] Optionally, two groups of transverse clamping assemblies are slidably connected to the workbench, with each group consisting of two transverse clamping assemblies, and the two transverse clamping assemblies are distributed along a transport direction perpendicular to the conveyor belt and are respectively placed on both sides of the conveyor belt.

[0012] By adopting the above technical solution, two transverse clamping assemblies are respectively placed on both sides of the conveyor belt, and the two sides of the steel grating are clamped through the sliding cooperation of the transverse clamping assemblies, thereby further improving the stability of the steel grating during the sawing process.

[0013] Optionally, the transverse clamping assembly includes a transverse clamping seat, which is placed on the workbench and slides on the workbench in a direction perpendicular to the conveyor belt transportation. The end of the longitudinal clamping seat is placed above the transverse clamping seat. An inclined guide column is fixed to the bottom end of the longitudinal clamping seat. The inclined guide column is inclined in a direction away from the longitudinal clamping seat, and an inclined guide groove is opened on the transverse clamping seat to face the inclined guide column.

[0014] By adopting the above technical scheme, the transverse clamping seat slides on the workbench, and the longitudinal clamping seat moves up and down on the conveyor belt. Through the mutual cooperation of the inclined guide column and the inclined guide groove, when the longitudinal clamping seat moves toward the direction of the conveyor belt, the transverse clamping seat is pushed toward the conveyor belt through the inclined guide column and the inclined guide groove. When the longitudinal clamping seat moves away from the conveyor belt, the transverse clamping seat is pushed away from the conveyor belt through the inclined guide column and the inclined guide groove, thereby realizing the linkage between the longitudinal clamping seat and the transverse clamping seat, so that the movement of one longitudinal clamping seat drives the two transverse clamping seats to move at the same time, thereby further improving the stability of the steel grating during the clamping process.

[0015] Optionally, a plurality of transverse shock-absorbing springs are fixedly provided on one side of the transverse clamping seat close to the conveyor belt, and a transverse clamping plate is fixedly provided on one end of the transverse shock-absorbing spring away from the transverse clamping seat.

[0016] By adopting the above technical scheme, when the transverse clamping seat drives the transverse clamping plate to move in the direction of the steel grating until the transverse clamping plate contacts the steel grating, the steel grating is sawed by the sawing assembly. The steel grating vibrates in the process of sawing, and the transverse shock-absorbing spring plays a role of mitigation and shock absorption. The vibration force generated on the steel grating is transmitted to the transverse shock-absorbing spring through the transverse clamping plate. The transverse shock-absorbing spring mitigates and dampens the transmitted vibration force, thereby protecting the transverse clamping seat.

[0017] Optionally, a plurality of longitudinal shock-absorbing springs are fixedly provided on a side of the longitudinal clamping seat close to the conveyor belt, and a longitudinal clamping plate is fixedly provided on one end of the longitudinal shock-absorbing spring away from the longitudinal clamping seat.

[0018] By adopting the above technical scheme, when the longitudinal clamping seat drives the longitudinal clamping plate to move in the direction of the steel grating until the longitudinal clamping plate contacts the steel grating, the steel grating is sawed by the sawing assembly. The steel grating vibrates in the process of sawing, and the longitudinal shock-absorbing spring plays a role of mitigation and shock absorption. The vibration force generated on the steel grating is transmitted to the longitudinal shock-absorbing spring through the longitudinal clamping plate. The longitudinal shock-absorbing spring mitigates and dampens the transmitted vibration force, thereby protecting the longitudinal clamping seat.

[0019] Optionally, a working cover is fixedly provided on the workbench, and the supporting frame is placed in the working cover.

[0020] By adopting the above technical solution, the working cover covers the support frame, sawing assembly, transverse clamping assembly and longitudinal clamping assembly inside, thereby protecting the sawing assembly, transverse clamping assembly and longitudinal clamping assembly. When the sawing assembly is sawing the steel grating, a large amount of sparks are generated, and the working cover also plays a role in isolating the sparks.

[0021] Optionally, the working cover is provided with a guide pipe connecting the inside of the working cover with the outside, and an exhaust fan is provided in the working cover, and the exhaust fan is placed at the end position of the guide pipe.

[0022] By adopting the above technical solution, smoke will be generated when the sawing assembly cuts the steel grating. At this time, the operator starts the exhaust fan, and the exhaust fan rotates to draw the smoke into the guide pipe, and the smoke is discharged through the guide pipe, thereby protecting the working environment near the sawing station.

[0023] Optionally, a feed rack is slidably connected to the conveyor belt at the feed end, and the feed rack slides along the direction of the conveyor belt. A power motor is fixed on the feed rack, and a driving shaft that is rotatably connected to the feed rack and is perpendicular to the transport direction of the conveyor belt is connected to the power motor. Driving gears are fixed at both ends of the driving shaft, and driving racks parallel to the transport direction of the conveyor belt are respectively fixed on both sides of the conveyor belt. The driving gears are meshingly connected with the driving racks, and a lifting cylinder is fixed on the feed rack. A connecting plate placed above the conveyor belt is fixed on the output shaft of the lifting cylinder. Two clamping rods are provided on the side of the connecting plate away from the feed rack, and a clamping cylinder is provided on the end of the clamping rod away from the connecting plate, and a clamping claw is provided on the output shaft of the clamping cylinder.

[0024] By adopting the above technical solution, when the operator places the steel grating on the conveyor belt at the feed end, the power motor rotates, and the rotation of the drive shaft drives the drive gear to rotate on the drive rack, thereby providing power for the feed rack. At this time, the telescopic movement of the lifting cylinder drives the connecting plate to move up and down in the vertical direction. At this time, the connecting plate drives the clamping rod to move, and then drives the clamping cylinder and the clamping claw to move. The steel grating is clamped through the connection and cooperation between the clamping cylinder and the clamping claw, which promotes the steel grating to perform more precise feeding movement, replacing the traditional manual marking, saving manpower and further improving the accuracy of the steel grating during the sawing process.

[0025] Optionally, the clamping rod is slidably connected to the connecting plate, the sliding direction of the clamping rod is perpendicular to the transport direction of the conveyor belt, and an adjusting rotating rod parallel to the sliding direction of the clamping rod is rotatably connected to the connecting plate, the two ends of the adjusting rotating rod are reverse-threaded, and the two clamping rods are respectively placed at the two ends of the adjusting rotating rod and are threadedly connected to the adjusting rotating rod.

[0026] By adopting the above technical solution, the operator can adjust the position of the clamping rod by turning the adjustment rod according to the actual specifications and shape of the steel grating, thereby changing the distance between the two clamping rods and improving the applicability of the clamping cylinder and the clamping claws to the steel grating.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. When the operator places the steel grating on the conveyor belt, the conveyor belt plays the role of transporting the steel grating. When the steel grating is transported to the appropriate position, the longitudinal cylinder drives the longitudinal clamping seat to move. The steel grating is clamped through the cooperation between the longitudinal clamping seat and the conveyor belt. At this time, the steel grating is sawed by the movement of the sawing assembly. The steel grating is clamped by the longitudinal clamping assembly, thereby improving the stability of the steel grating during sawing, which has the effect of improving the sawing accuracy of the steel grating.

[0029] 2. The operator starts the driving motor, and the output shaft of the driving motor rotates, which in turn drives the connecting shaft to rotate through the belt, and finally realizes the rotation of the circular saw blade. The steel grating is sawed by the rotation of the circular saw blade. When the belt is loose between the connecting shaft and the output shaft of the driving motor, the operator rotates the adjustment plate, and adjusts the tightness of the belt by adjusting the inclination of the adjustment plate on the sawing frame, which makes it easier for the operator to replace the belt and adjust the tightness of the belt. When the inclination of the adjustment plate is adjusted, the adjustment screw and the adjustment nut cooperate with each other, and the adjustment nut is turned to limit the position of the adjustment plate. The adjustment plate is clamped by two adjustment nuts, thereby improving the stability of the adjustment plate;

[0030] 3. The transverse clamping seat slides on the workbench, and the longitudinal clamping seat moves up and down on the conveyor belt. Through the cooperation of the inclined guide column and the inclined guide groove, when the longitudinal clamping seat moves toward the direction of the conveyor belt, the transverse clamping seat is pushed toward the conveyor belt through the inclined guide column and the inclined guide groove. When the longitudinal clamping seat moves away from the conveyor belt, the transverse clamping seat is pushed away from the conveyor belt through the inclined guide column and the inclined guide groove, thereby realizing the linkage between the longitudinal clamping seat and the transverse clamping seat, so that the movement of one longitudinal clamping seat drives the two transverse clamping seats to move at the same time, further improving the stability of the steel grating during the clamping process.

[0039] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0040] The embodiment of the present application discloses a mobile circular saw.

[0041] Reference Figure 1 and Figure 2 A mobile circular saw comprises a workbench 1, on which two conveyor belts 2 close to each other are installed, and the conveyor belts 2 are horizontal and linearly distributed. A support frame 3 placed above the conveyor belts 2 is fixed on the workbench 1, and a sawing assembly 4 is slidably connected to the support frame 3. The sawing assembly 4 is placed between the two conveyor belts 2, and the sliding direction of the sawing assembly 4 is perpendicular to the transportation direction of the conveyor belts 2. When the operator places the steel grating on the conveyor belt 2, the conveyor belt 2 transports the steel grating. When the steel grating is transported to a suitable position, the steel grating is transversely sawed by the movement of the sawing assembly 4 to complete the sawing process of the steel grating.

[0042] Reference Figure 2 and Figure 3 The sawing assembly 4 includes a sawing frame 41 and two driving cylinders 49. The sawing frame 41 slides in a horizontal direction on the support frame 3. The driving cylinder 49 is horizontal and fixedly connected to the inner wall of the support frame 3. The output shaft of the driving cylinder 49 is fixedly connected to the sawing frame 41, and the movement of the driving cylinder 49 drives the sawing frame 41 to slide on the support frame 3. A circular saw blade 42 placed between two conveyor belts 2 is rotatably connected below the sawing frame 41, and the circular saw blade 42 is vertical. A connecting shaft 43 coaxial with the circular saw blade 42 is fixedly provided on one side of the circular saw blade 42, and the connecting shaft 43 is horizontal. An adjusting plate 46 is installed on the sawing frame 41, and a driving motor 45 is fixedly provided on the adjusting plate 46. The output shaft of the driving motor 45 is connected to the connecting shaft 43 through a belt 44. The operator starts the driving motor 45 , and the output shaft of the driving motor 45 rotates, which in turn drives the connecting shaft 43 to rotate through the belt 44 , and finally realizes the rotation of the circular saw blade 42 , and the steel grating is sawed by the rotation of the circular saw blade 42 .

[0043] Reference Figure 2 and Figure 3 One end of the adjustment plate 46 is hinged to the sawing frame 41, and two adjustment screws 47 are hinged on the sawing frame 41 and are placed on the other end of the adjustment plate 46. The adjustment screw 47 passes through the adjustment plate 46 and moves inside the adjustment plate 46. The adjustment screw 47 is threadedly connected to two adjustment nuts 48 placed on both sides of the adjustment plate 46. When the belt 44 is loose between the connecting shaft 43 and the output shaft of the driving motor 45, the operator rotates the adjustment plate 46, and adjusts the tightness of the belt 44 by adjusting the inclination of the adjustment plate 46 on the sawing frame 41, so that it is convenient for the operator to replace the belt 44 and adjust the tightness of the belt 44. When the inclination of the adjustment plate 46 is adjusted, the adjustment screw 47 and the adjustment nut 48 cooperate with each other, and the adjustment nut 48 is screwed to limit the position of the adjustment plate 46. The two adjustment nuts 48 clamp the adjustment plate 46 to improve the stability of the adjustment plate 46.

[0044] Reference Figure 2 and Figure 3The support frame 3 is fixed with two longitudinal clamping assemblies 5 placed above the conveyor belt 2. The two longitudinal clamping assemblies 5 are distributed along the transport direction of the conveyor belt 2 and are respectively placed on both sides of the sawing assembly 4. The longitudinal clamping assembly 5 includes two vertical longitudinal cylinders 51. The longitudinal cylinders 51 are fixedly connected to the support frame 3. The output shaft of the longitudinal cylinder 51 is fixed with a longitudinal clamping seat 52 placed above the conveyor belt 2. The longitudinal clamping seat 52 is horizontal. When the steel grating is transported to a suitable position, the longitudinal cylinder 51 drives the longitudinal clamping seat 52 to move. The steel grating is clamped by the mutual cooperation between the longitudinal clamping seat 52 and the conveyor belt 2. At this time, the steel grating is sawed by the movement of the sawing assembly 4. The clamping of the steel grating by the longitudinal clamping assembly 5 improves the stability of the steel grating during sawing, and further improves the accuracy of the steel grating during sawing.

[0045] Reference Figure 2 and Figure 3 Five vertical longitudinal shock-absorbing springs 53 are fixedly arranged on the side of the longitudinal clamping seat 52 close to the conveyor belt 2, and a horizontal longitudinal clamping plate 54 is fixedly arranged on the end of the longitudinal shock-absorbing spring 53 away from the longitudinal clamping seat 52. When the longitudinal clamping seat 52 drives the longitudinal clamping plate 54 to move in the direction of the steel grating until the longitudinal clamping plate 54 contacts the steel grating, the steel grating is sawed by the sawing assembly 4 at this time, and the steel grating vibrates during the sawing process, and the longitudinal shock-absorbing spring 53 plays a role of mitigation and shock absorption. The vibration force generated on the steel grating is transmitted to the longitudinal shock-absorbing spring 53 through the longitudinal clamping plate 54, and the vibration force transmitted is mitigated and damped by the longitudinal shock-absorbing spring 53, thereby protecting the longitudinal clamping seat 52.

[0046] Reference Figure 2 and Figure 3 Two groups of transverse clamping assemblies 6 are slidably connected to the workbench 1, each group consists of two transverse clamping assemblies 6, and the two transverse clamping assemblies 6 are distributed along the transport direction perpendicular to the conveyor belt 2 and are respectively placed on both sides of the conveyor belt 2. The two transverse clamping assemblies 6 and one longitudinal clamping assembly 5 are placed in the same vertical plane. Through the sliding cooperation of the transverse clamping assemblies 6, the two sides of the steel grating are clamped, further improving the stability of the steel grating during the sawing process.

[0047] Reference Figure 2 and Figure 4The transverse clamping assembly 6 includes a transverse clamping seat 61, which is placed on the workbench 1 and slides on the workbench 1 in a direction perpendicular to the conveying direction of the conveyor belt 2. The end of the longitudinal clamping seat 52 is placed directly above the transverse clamping seat 61. An inclined guide column 55 is fixed at the bottom end of the longitudinal clamping seat 52, and the inclined guide column 55 is inclined in a direction away from the longitudinal clamping seat 52. An inclined guide groove 64 facing the inclined guide column 55 is provided on the transverse clamping seat 61. The longitudinal clamping seat 52 moves up and down on the conveyor belt 2. Through the mutual cooperation of the inclined guide column 55 and the inclined guide groove 64, when the longitudinal clamping seat 52 moves in the direction of the conveyor belt 2, the transverse clamping seat 61 is pushed in a direction close to the conveyor belt 2 through the inclined guide column 55 and the inclined guide groove 64. When the longitudinal clamping seat 52 moves in the direction away from the conveyor belt 2, the transverse clamping seat 61 is pushed in the direction away from the conveyor belt 2 through the inclined guide column 55 and the inclined guide groove 64, thereby realizing the linkage between the longitudinal clamping seat 52 and the transverse clamping seat 61, so that the movement of one longitudinal clamping seat 52 drives the two transverse clamping seats 61 to move at the same time, thereby further clamping the steel grating.

[0048] Reference Figure 2 and Figure 4 , three horizontal transverse shock-absorbing springs 62 are fixedly arranged on the side of the transverse clamping seat 61 close to the conveyor belt 2, and a vertical transverse clamping plate 63 is fixedly arranged on the end of the transverse shock-absorbing spring 62 away from the transverse clamping seat 61. When the transverse clamping seat 61 drives the transverse clamping plate 63 to move in the direction of the steel grating until the transverse clamping plate 63 contacts the steel grating, the steel grating is sawed by the sawing assembly 4 at this time, and the steel grating vibrates during the sawing process, and the transverse shock-absorbing spring 62 plays a role of mitigation and shock absorption. The vibration force generated on the steel grating is transmitted to the transverse shock-absorbing spring 62 through the transverse clamping plate 63, and the vibration force transmitted is mitigated and damped by the transverse shock-absorbing spring 62, thereby protecting the transverse clamping seat 61.

[0049] Reference Figure 1 and Figure 2 A working cover 7 is fixedly provided on the workbench 1, and the supporting frame 3 is placed in the working cover 7. The working cover 7 covers the supporting frame 3, the sawing assembly 4, the transverse clamping assembly 6 and the longitudinal clamping assembly 5 inside, so as to protect the sawing assembly 4, the transverse clamping assembly 6 and the longitudinal clamping assembly 5. When the sawing assembly 4 is sawing the steel grating, a large amount of sparks are generated, and the working cover 7 also plays a role in isolating the sparks.

[0050] Reference Figure 1 and Figure 2 A working door 8 is hinged on the working cover 7 to connect the inside of the working cover 7 with the outside. When the sawing component 4, the transverse clamping component 6 or the longitudinal clamping component 5 fails, the operator opens the working door 8 to facilitate the operator to saw the internal sawing component 4, the transverse clamping component 6 or the longitudinal clamping component 5, thereby facilitating the operator's operation and use.

[0051] Reference Figure 2 and Figure 5 On one side of the working cover 7, two guide pipes 9 are fixedly provided to connect the inside of the working cover 7 with the outside. An exhaust fan 10 is fixedly provided inside the working cover 7. The exhaust fan 10 is placed at the end of the guide pipe 9 close to the working cover 7. When the sawing assembly 4 saws the steel grating, smoke will be generated. At this time, the operator starts the exhaust fan 10, and the exhaust fan 10 rotates to draw the smoke into the guide pipe 9, and the smoke is discharged through the guide pipe 9, so as to further protect the working environment near the sawing station.

[0052] Reference Figure 6 , a horizontal feed rack 11 is slidably connected to the conveyor belt 2 at the feed end, and the feed rack 11 slides along the direction of the conveyor belt 2. A power motor 12 is fixed on the feed rack 11, and a drive shaft 13 perpendicular to the transport direction of the conveyor belt 2 is rotatably connected to the feed rack 11. The drive shaft 13 is horizontal, and the power motor 12 and the drive shaft 13 are connected to each other. Drive gears 14 are fixed at both ends of the drive shaft 13, and drive racks 21 parallel to the transport direction of the conveyor belt 2 are fixed on both sides of the conveyor belt 2. The drive rack 21 is horizontal, and the drive gear 14 is meshed and connected with the drive rack 21. When the operator places the steel grating on the conveyor belt 2 at the feed end, the power motor 12 rotates, and the rotation of the drive shaft 13 drives the drive gear 14 to rotate on the drive rack 21, thereby providing power for the feed rack 11.

[0053] Reference Figure 6 Two vertical lifting cylinders 15 are fixed on the feed rack 11, and a connecting plate 16 placed above the conveyor belt 2 is fixed on the output shaft of the lifting cylinder 15. The connecting plate 16 is horizontal and placed on the feed rack 11 to slide in the vertical direction. The telescopic movement of the lifting cylinder 15 drives the connecting plate 16 to move up and down in the vertical direction.

[0054] Reference Figure 6 and Figure 7 Two clamping rods 17 are installed on the side of the connecting plate 16 away from the feeding rack 11. A clamping cylinder 19 is fixed on one end of the clamping rod 17 away from the connecting plate 16. A clamping claw 18 is installed on the output shaft of the clamping cylinder 19. The steel grating is clamped by the connection and cooperation between the clamping cylinder 19 and the clamping claw 18. The power motor 12 and the lifting cylinder 15 replace the manual and traditional conveyor belt 2 transportation mode, and promote the steel grating to perform more precise feeding movement, replacing the traditional manual marking, saving manpower and further improving the accuracy of the steel grating during the sawing process.

[0055] Reference Figure 7The clamping rod 17 is slidably connected to the connecting plate 16. The clamping rod 17 slides in the horizontal direction. The sliding direction of the clamping rod 17 is perpendicular to the transport direction of the conveyor belt 2. The connecting plate 16 is rotatably connected with an adjusting rotating rod 20 which is parallel to the sliding direction of the clamping rod 17. The two ends of the adjusting rotating rod 20 are in reverse thread shape. The two clamping rods 17 are respectively placed at the two ends of the adjusting rotating rod 20 and are threadedly connected to the adjusting rotating rod 20. A circular adjusting rotating handle 201 is fixed at one end of the adjusting rotating rod 20. According to the actual specifications and shape of the steel grating, the operator rotates the adjusting rotating handle 201, thereby driving the adjusting rotating rod 20 to rotate, thereby changing the distance between the two clamping rods 17, realizing the adjustment of the distance between the two clamping claws 18, and finally expanding the applicable scope of the clamping cylinder 19 and the clamping claws 18 for clamping the steel grating.

[0056] The implementation principle of a mobile circular saw in an embodiment of the present application is as follows: the operator first adjusts the inclination of the adjustment plate 46 on the sawing frame 41 to make the belt 44 between the output shaft of the driving motor 45 and the connecting shaft 43 in a taut state, and then screws the adjustment nut 48, and tightens the position of the adjustment plate 46 by adjusting the nut 48 and the adjustment screw 47. At this time, the steel grating is placed on the conveyor belt 2, and the claws 18 clamp the steel grating through the cooperation of the power motor 12, the lifting cylinder 15 and the clamping cylinder 19, so that the steel grating is accurately transported, and then the steel grating is clamped by the longitudinal clamping assembly 5 and the transverse clamping assembly 6, and finally the steel grating is sawed by the sawing assembly 4, so as to achieve stable cutting of the steel grating.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
