[0028] A long-life annular wall cutting machine, as shown in FIG. 1, FIG. 2 and FIG. 3, includes a housing, a water cooling chamber 1 and an annular saw blade fixing and protecting cover assembly 2. Driving box cooling fins 3 and a motor 26 driver 4 are mounted in the water cooling chamber 1. By providing the water cooling chamber 1, the water cooling chamber 1 can effectively reduce temperatures of the driving box cooling fins 3 and the motor 26 driver 4, thereby preventing overheating and prolonging the life of the wall cutting machine. Specifically, the long-life annular wall cutting machine further includes a motor 26 for driving the wall cutting machine and a water tube 14. The motor 26 is driven by the motor 26 driver 4, and a body of the water tube 14 passes through the water cooling chamber 1. One end of the water tube 14 is provided with a water inlet 15, and the other end of the water tube 14 is provided with a first cooling water outlet 16 and a second cooling water outlet 17. One side of the water cooling chamber 1 is provided with an air inlet 18, the air inlet 18 is directly opposite the driving box cooling fins 3, and the other side of the water cooling chamber 1 is provided with an air outlet 19. The motor 26 driver 4 can realize energy-saving operation of the motor 26. By optimizing operation parameters of the motor 26, such as reducing the voltage and improving the efficiency, the energy consumption of the motor 26 can be reduced, thereby realizing the goal of energy saving and emission reduction. Moreover, with the dual heat dissipation structure of the water cooling chamber 1 and air cooling, the heat dissipation capacity of heating elements of the driver is effectively improved. This design enables the machine to work continuously under heavy load, which prolongs the service life of the wall cutting machine and improves the operational safety. With the design of the water tube 14, cooling water can circulate. The cooling water enters via the water inlet 15, passes through the water cooling chamber 1, and is discharged from the first cooling water outlet and the second cooling water outlet 17. This design helps to maintain the flow and temperature control of the cooling water. Moreover, the design of the air inlet 18 and the air outlet 19 helps to simplify the maintenance and cleaning of the wall cutting machine.
[0029] As shown in FIG. 1, FIG. 2 and FIG. 4, the annular saw blade fixing and protecting cover assembly 2 is arranged on one side of the water cooling chamber 1. The annular saw blade fixing and protecting cover assembly 2 provides physical protection for the saw blade, prevents the saw blade from accidentally popping out or being damaged, and protects the operator from injury. Specifically, a power wheel 5 is arranged in the annular saw blade fixing and protecting cover assembly 2, an annular saw blade 6 is arranged in a middle of the power wheel 5, and a taper fitting surface 7 is arranged between the power wheel 5 and the annular saw blade 6. The taper fitting surface 7 between the power wheel 5 and the annular saw blade 6 can ensure stable transmission of power and keep the saw blade stable during high-speed rotation, thereby ensuring the cutting accuracy.
[0030] As shown in FIG. 1, FIG. 2 and FIG. 4, one side of the power wheel 5 is provided with an output shaft 8, and an elastic member is mounted between the output shaft and the power wheel. Specifically, the output shaft 8 is provided with a gasket 9, and a waved elastic pad 10 is mounted between the gasket 9 and the power wheel 5. Further, wave fluctuations of the waved elastic pad 10 are perpendicular to the annular saw blade 6. The gasket 9 on the output shaft 8 and the waved elastic pad 10 help to reduce the vibration and noise during power transmission, thereby providing a smoother operation experience, protecting the wall cutting machine and prolonging the service life of the long-life annular wall cutting machine. A tensioning handwheel adjustment indicator light 35 is arranged on top of the water cooling chamber 1. The tensioning handwheel adjustment indicator light 35 on top of the water cooling chamber 1 provides direct feedback. With the design of the tensioning handwheel adjustment indicator light 35, the operator can accurately determine whether the tensioning handwheel 23 is adjusted to an appropriate strength, thereby improving the safety performance of the wall cutting machine during use. If the contact strength is too small or too large, the indicator light of the brushless motor 26 driver 4 will turn yellow or red. If the strength is appropriate, the indicator light will turn green. The other side of the power wheel 5 is provided with a pressing plate bolt 12, and a small pressing plate 13 is mounted between the pressing plate bolt 12 and the power wheel 5. The design of the pressing plate bolt 12 and the small pressing plate 13 can ensure close fitting between the power wheel 5 and the saw blade and prevent the saw blade from sliding or shifting during high-speed rotation, thereby improving the cutting accuracy and efficiency. Moreover, with the design of the pressing plate bolt 12 and the small pressing plate 13, the holddown state of the power wheel 5 and the saw blade can be adjusted rapidly, which is convenient for the maintenance and replacement of the saw blade.
[0031] Further, as shown in FIG. 1 and FIG. 2, the annular saw blade fixing and protecting cover assembly 2 further includes a first saw blade holddown handwheel 20 and a second saw blade holddown handwheel 21, and the first saw blade holddown handwheel 20 and the second saw blade holddown handwheel 21 are arranged on a same side wall of the annular saw blade fixing and protecting cover assembly 2. With the above arrangement, the annular saw blade fixing and protecting cover assembly 2 and the motor 26 output shaft 8 can be assembled more easily. The arrangement of the first saw blade holddown handwheel 20 and the second saw blade holddown handwheel 21 allows the operator to adjust the holddown state of the saw blade rapidly, thereby improving the operating efficiency. Moreover, the annular saw blade fixing and protecting cover assembly and the output shaft are locked by a bolt, thereby making the assembly less complicated. The locking mechanism is simple in structure, and can realize rapid adjustment of the angle of the protecting cover. Thereby, the saw blade has wide applicability and can meet different cutting demands.
[0032] As shown in FIG. 1 and FIG. 2, the annular saw blade fixing and protecting cover assembly 2 further includes a water retaining plate 22 and a tensioning handwheel 23. The water retaining plate 22 is arranged on a side of the annular saw blade fixing and protecting cover assembly 2 close to the first saw blade holddown handwheel 20. The tensioning handwheel 23 is arranged on the annular saw blade fixing and protecting cover assembly 2 directly opposite the annular saw blade 6. The water retaining plate 22 arranged can prevent the coolant or water from entering the saw blade and driving components, thereby protecting the motor 26 and the driver from liquid erosion and prolonging the service life of the wall cutting machine. Moreover, the presence of the water retaining plate 22 can prevent the operator from being affected by the splashing coolant or water or from slipping during construction, thereby improving the safety of the construction site. With the arrangement of the tensioning handwheel 23, the operator can adjust the tension of the saw blade rapidly to make the saw blade meet different cutting demands, thereby making the operation more convenient and flexible. With the tensioning handwheel 23, the tension of the saw blade can be accurately controlled, which ensures the stability of the saw blade during high-speed rotation, thereby improving the cutting accuracy and quality.
[0033] As shown in FIG. 1 and FIG. 2, a switch 24 is further arranged on top of the housing, and one side of the switch 24 is provided with the tensioning handwheel adjustment indicator light 35. The tensioning handwheel adjustment indicator light 35 can accurately show the tensioning state of the saw blade, thereby avoiding the safety accidents caused by improper tensioning strength, and improving the safety performance of the wall cutting machine during use. Further, one end of the power wheel 5 is further provided with a head shell 27, and two sides of the head shell 27 are respectively provided with a first guide rail 28 and a second guide rail 11. With the arrangement of the first guide rail 28 and the second guide rail 11, the stability and straightness of the saw blade during cutting can be ensured, thereby improving the cutting accuracy; and the movement range of the saw blade can be limited, thereby reducing accident risks caused by improper operation, thereby improving the construction safety.
