[0030] Embodiment 1

[0031] See also Figure 1-Figure 3 As shown in the figure, an adjustable spark-proof cutting device for building steel includes a support frame 100, a servo motor 200 is fixedly connected to the inside of the support frame 100, and a cutting wheel 300 is connected to the side of the servo motor 200 through its output shaft;

[0032] The support frame 100 is provided with a blocking assembly 400 inside, and the blocking assembly 400 includes a hydraulic chamber 410. Among them, the side of the cutting wheel 300 is connected to a disc 420 through its output shaft transmission, the outer side of the disc 420 is rotatably connected to a torsion spring rod 430, the outer side of the torsion spring rod 430 is fixedly connected to a power rod 440, and one end of the hydraulic chamber 410 is connected to a force rod 450 by a piston sliding, and the force rod 450 is located at the front end of the power rod 440, and the force rod 450 is in contact with the power rod 440. When the servo motor 200 is started, the cutting wheel 300 connected to its output shaft transmission can be driven to rotate, and at this time, the cutting wheel 300 drives the disc 420 connected to its output shaft transmission to rotate clockwise, and the disc 420 drives the power rod 440 connected to it through the torsion spring rod 430 to rotate, and the power rod 440 is squeezed by the force rod 450, and rotates with the torsion spring rod 430 as the axis, and at this time, the force rod 450 cannot move. The other end of the hydraulic chamber 410 is slidably connected to a push rod 460. In this way, when the rotation speed is too fast and sparks are generated, the servo motor 200 can be used to change the direction of the disc 420 to make it rotate counterclockwise. At this time, the power rod 440 squeezes the force rod 450. Because the power rod 440 is restricted by the disc 420 and cannot rotate with the torsion spring rod 430 as the axis, the power rod 440 squeezes the force rod 450 and moves it, and cooperates with the hydraulic chamber 410 that is slidably connected to the piston of the force rod 450, so that the pressure in the hydraulic chamber 410 increases, driving the push rod 460 that is slidably connected to the piston of the hydraulic chamber 410 to move. The front end of the force rod 450 is fixedly connected to a spring 470, one end of the spring 470 is fixedly connected to the force rod 450, and the spring 470 is fixedly connected to the inner wall of the hydraulic chamber 410. The bottom of the push rod 460 is fixedly connected to a blocking plate 480. When the push rod 460 is in a moving state, the push rod 460 drives the blocking plate 480 fixedly connected thereto to move downward to perform isolation, thereby reducing the possibility of sparks flying due to over-fast cutting, thereby reducing the impact on nearby workers.

[0033] When in use, the servo motor 200 is started to drive the cutting wheel 300 connected to its output shaft to rotate. At this time, the cutting wheel 300 drives the disc 420 connected to its output shaft to rotate clockwise. The disc 420 drives the power rod 440 connected to it through the torsion spring rod 430 to rotate. The power rod 440 is squeezed by the force rod 450 and rotates with the torsion spring rod 430 as the axis. At this time, the force rod 450 cannot move. When the speed is too fast and sparks are generated, the servo motor 200 is used to change the speed of the disc 420. The power rod 440 squeezes the force-bearing rod 450 and moves it, and cooperates with the hydraulic chamber 410 that is slidably connected to the piston of the force-bearing rod 450, so that the pressure in the hydraulic chamber 410 increases, driving the push rod 460 that is slidably connected to the piston of the hydraulic chamber 410 to move, so that the push rod 460 drives the blocking plate 480 fixedly connected to it to move downward for partition.

[0034] For improved stability at high speeds, see Figure 1-Figure 4 As shown in the figure, a support assembly 500 is arranged on the outer side of the support frame 100, and the support assembly 500 includes a transmission gear rod 510. The side of the support frame 100 is provided with an opening, and the transmission gear rod 510 passes through the opening, and the transmission gear rod 510 is fixedly connected to the force rod 450. When the force rod 450 moves, the transmission gear rod 510 fixedly connected to the force rod 450 can be driven to move. The front and rear ends of the support frame 100 are rotatably connected to the rotating shaft 520, and the side of the rotating shaft 520 is fixedly connected to the gear 530. The transmission gear rod 510 is located at the outer side of the gear 530, and the transmission gear rod 510 and the gear 530 are in a meshing state. When the transmission gear rod 510 is in a moving state, the transmission gear rod 510 drives the gear 530 meshed with it to rotate, and the gear 530 drives the rotating shaft 520 fixedly connected to it to rotate. The outer side of the rotating shaft 520 is fixedly connected to a support plate 540. When the rotating shaft 520 is in a rotating state, the rotating shaft 520 drives the supporting plate 540 fixedly connected thereto to rotate to the ground position for support, thereby improving the stability of the device when the rotation speed is too fast.

[0035] When in use, when the force-bearing rod 450 moves, it can drive the transmission gear rod 510 fixedly connected to the force-bearing rod 450 to move, so that the transmission gear rod 510 drives the gear 530 meshing with it to rotate, and the gear 530 drives the rotating shaft 520 fixedly connected to it to rotate, so that the rotating shaft 520 drives the support plate 540 fixedly connected to it to rotate to the ground position for support.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
