[0022] See attached document Figures 1-4 This utility model provides a sawing assembly for a cold-cutting flying saw, including a support platform 100. A movable guide rail 110 is slidably connected to the top of the outer wall of the support platform 100. The movable guide rail 110 is configured to drive a pneumatically controlled guide rail 200 and a pipe clamp 120 to slide back and forth on the top of the outer wall of the support platform 100. A power box 210 is disposed above the top of the outer wall of the movable guide rail 110. A cutting saw disc 220 is installed at the output end of the power box 210. The top of the outer wall of the support platform 100 is located at the cutting... A pipe clamp 120 for holding pipes is provided on one side of the cutting saw 220. The bottom of the outer wall of the power box 210 is connected to the top of the outer wall of the moving guide rail 110 through the pneumatic guide rail 200. The pneumatic guide rail 200 is provided to drive the power box 210 to move left and right, so that the cutting saw 220 can cut the pipes. A pneumatic moving device can be provided at the bottom of the pipe clamp 120 so that the upper end of the pipe clamp 120 can cut the pipes to be cut.

[0023] The outer wall of the cutting saw disc 220 is covered by a saw disc protective component 300. The saw disc protective component 300 includes an upper fixed sleeve 310, the outer wall of which is fixed to the front end of the outer wall of the power box 210. Both ends of the upper fixed sleeve 310 are provided with bottom movable sleeves 320, forming a ring. The cutting saw disc 220 is mounted on the outer walls of the upper fixed sleeve 310 and the bottom movable sleeves 320. The outer walls of the bottom movable sleeves 320 are detachably equipped with sealing plates 324 at both the front and rear ends. The detachable sealing plates 324 facilitate subsequent replacement of the cutting saw disc 220 and prevent the sealing plates 324 from interfering with the replacement process. The outer walls of the bottom movable sleeves 320 are integrally fixed with fixing pins 323 on both the front and rear sides. Multiple fixing pins 323 are evenly arranged in an array. The sealing plate 324 is provided with a fixing groove on the outer side of the sealing plate 324 and at the corresponding position of the fixing pin 323. The sealing plate 324 is connected to the fixing pin 323 through the groove. The sealing plate 324 can be fixedly fastened to the outer wall of the bottom moving sleeve 320 through the fixing pin 323 and the groove. This allows the sealing plate 324 to protect the cutting saw disc 220 in normal use. A rotating support arm 321 is integrally fixed to one end of the sealing plate 324 near the upper fixing sleeve 310. The other end of the rotating support arm 321 is connected to the corresponding position of the front and rear ends of the outer wall of the upper fixing sleeve 310 through bolts. The rotating support arm 321 and the bolt are connected through a bearing seat. Personnel can use a wrench to thread the bolt to the screw hole on the outer wall of the rotating support arm 321. At the same time, the bottom moving sleeve 320 can also rotate on the outer wall of the bolt through the bearing seat.

[0024] A short plate 322 is fixed to the top of the outer wall of the bottom moving sleeve 320 and the end near the upper fixed sleeve 310. A small winch 330 is fixed to the top of the outer wall of the upper fixed sleeve 310 by a bracket. Fixed pulleys 331 are installed on both sides of the top of the outer wall of the upper fixed sleeve 310 and the small winch 330. Two sets of pull ropes 332 are wound around the outer wall of the small winch 330. The other end of the pull rope 332 is fixedly connected to the side wall of the short plate 322 after passing over the fixed pulleys 331. Specifically, when in use, the micro motor on the small winch 330 can be started by powering on, so that the small winch 330 can wind up the pull rope 332, so that the pull rope 332 can pull the bottom moving sleeve 320 outward through the short plate 322 to expose the end of the cutting saw disc 220, so that the pipe can be cut.

[0025] The usage process of this utility model is as follows: Those skilled in the art can first assemble the device according to the above instructions, then connect an external power supply to all electrical equipment, and control the operation of the device through an external controller. During use, personnel can power on the micro motor on the small winch 330, enabling the small winch 330 to wind up the pull rope 332. This allows the pull rope 332 to pull the bottom moving sleeve 320 outwards around the rotating support arm 321 via the short plate 322, exposing the end of the cutting saw disc 220. Then, personnel can pre-load the saw through the pipe clamp. The tool 120 clamps and fixes the pipe fittings, and then the power box 210 is started to move towards the pipe fittings through the pneumatic guide rail 200, so that the outer wall of the cutting saw 220 can cut the pipe fittings when it comes into contact with them. At the same time, the position of the power box 210 can be adjusted by the moving guide rail 110, so that the cutting saw 220 can cut more pipe fittings. After the cutting is completed, the operator can rotate the small winch 330 in the opposite direction to release the pull rope 332. Under the action of gravity, the bottom moving sleeve 320 will rotate downward to wrap and protect the exposed part of the cutting saw 220.

[0026] When the cutting saw disc 220 needs to be replaced, the operator can unscrew the bolts fixing the rotating support arm 321 at the front end, then pull the sealing plate 324 outward to remove it, and then remove the bolt group fixing the cutting saw disc 220 to replace it.

[0027] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
