A second transmission wheel 23 is fixedly sleeved on the output end of the second motor 22, and the outer surface of the second transmission wheel 23 is meshed with the outer surface of the first transmission wheel 21. A moving block 24 is movably embedded in the inner surface of the moving frame 19. A threaded lead screw 25 is movably inserted into the inner surface of the moving block 24.

A cutting device 27 is fixedly installed at the bottom of the moving block 24.

[0024] The effect achieved by the entire embodiment 1 is that when the guardrail moves to a suitable position, first, under the action of the telescopic rod 17, the fixing plate 16 is driven to move downward, thereby squeezing and fixing the guardrail to prevent the guardrail from shifting during cutting. Then, the cutting device 27 is started. Under the action of the second motor 22, the second transmission wheel 23 is driven to rotate, and under the action of the first transmission wheel 21, the threaded rod 20 is driven to rotate, thereby driving the moving frame 19 to move downward and driving the cutting device 27 to move downward to a suitable position. At the same time, under the action of the third motor 26, the threaded lead screw 25 is driven to rotate, thereby driving the moving block 24 to move and driving the cutting device 27 to move, thus completing the cutting of the guardrail and avoiding the problem that the staff needs to manually fix the guardrail, greatly improving the practicability of the equipment.

[0025] Embodiment 2: As Figures 2-4As shown, a plurality of conveying shafts 2 are movably inserted between the inner walls of the mounting frame 1. Meshing wheels 3 are fixedly sleeved on the outer walls of the plurality of conveying shafts 2. A chain 4 is movably sleeved between the outer walls of the plurality of meshing wheels 3. A first gear 5 is fixedly sleeved on the outer wall of one of the plurality of conveying shafts 2. A first motor 6 is fixedly installed on one side of the outer wall of the mounting frame 1. A second gear 7 is fixedly sleeved on the output end of the first motor 6. The outer wall of the second gear 7 is meshed with the outer wall of the first gear 5. A bottom plate 8 is fixedly installed at the bottom of the inner wall of the mounting frame 1. A cutting groove 9 is formed at the top of the bottom plate 8. A water storage tank 10 is fixedly installed on one side of the inner wall of the mounting frame 1. A conveying pipe 11 is fixedly communicated with the top of the water storage tank 10. Two spray heads 12 are fixedly communicated with the outer wall of the conveying pipe 11. The outer walls of the spray heads 12 are fixedly inserted into the inner walls of the support plates 14. A water pump 13 is fixedly installed on the top of the water storage tank 10. The water pump 13 is arranged on the outer wall of the conveying pipe 11.

[0026] The overall effect achieved by the entire Embodiment 2 is that when the guardrail needs to be cut, first, the guardrail is carried onto the conveying shaft 2. Then, under the action of the first motor 6, the second gear 7 is driven to rotate. At the same time, under the action of the first gear 5, the conveying shaft 2 is driven to rotate. And under the action of the meshing wheels 3 and the chain 4, the guardrail can be driven to move forward. When it moves to the top of the bottom plate 8, the first motor 6 stops working. Subsequently, the guardrail is fixed and cut. While cutting, under the action of the water pump 13 and the conveying pipe 11, the tap water inside the water storage tank 10 is sent into the spray heads 12 and sprayed out from the spray heads 12, which plays a role in cooling the guardrail, avoiding damage to the guardrail due to excessive temperature during cutting. At the same time, it can also reduce the temperature of the waste chips during cutting, avoiding harm to the staff caused by the waste chips with too high temperature, greatly improving the practicability of the equipment.

[0027] Working principle: When it is necessary to use the cutting machine to cut the guardrail, first move the guardrail onto the conveying shaft 2. Then, under the action of the first motor 6, the second gear 7 is driven to rotate. At the same time, under the action of the first gear 5, the conveying shaft 2 is driven to rotate. And under the action of the meshing wheel 3 and the chain 4, the guardrail can be driven to move forward. When it moves to the top of the bottom plate 8, the first motor 6 stops working. Subsequently, under the action of the telescopic rod 17, the fixing plate 16 is driven to move downward, so as to squeeze and fix the guardrail, avoiding the displacement of the guardrail during cutting. Then start the cutting device 27. Under the action of the second motor 22, the second transmission wheel 23 is driven to rotate. And under the action of the first transmission wheel 21, the threaded rod 20 is driven to rotate, thereby driving the movable frame 19 to move downward and driving the cutting device 27 to move downward to a suitable position. At the same time, under the action of the third motor 26, the threaded screw rod 25 is driven to rotate, thereby driving the movable block 24 to move and driving the cutting device 27 to move, thus completing the cutting of the guardrail. During cutting, under the action of the water pump 13 and the conveying pipe 11, the tap water inside the water storage tank 10 is sent into the nozzle 12 and sprayed out from the nozzle 12, playing a role in cooling the guardrail, avoiding damage to the guardrail due to excessive temperature during cutting. At the same time, it can also reduce the temperature of the waste chips during cutting, avoiding harm to the staff caused by high-temperature waste chips, and improving the actual use effect of the cutting device.
