DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-3 This application is described in further detail.

[0022] The embodiment of the present application discloses a wire threading mechanism for fire protection engineering. Figure 1-3 A threading mechanism for fire protection engineering includes a movable column 1 and a plurality of mounting tubes 4. The plurality of mounting tubes 4 are evenly distributed around the movable column 1 in an equidistant circular array. The outer wall of the movable column 1 is connected to the plurality of mounting tubes 4 through an adaptive internal support mechanism.

[0023] The adaptive inner support mechanism includes a sliding sleeve 2 and an inner support spring 3. The two sliding sleeves 2 are slidably connected to the outer wall of the movable column 1. The inner support spring 3 is sleeved on the outer wall of the movable column 1, and its two ends are respectively against the two sliding sleeves 2. The outer wall of the sliding sleeve 2 is fixedly connected to a plurality of connecting seats 5. The inner wall of the connecting seat 5 is rotatably connected to a connecting rod 6. The end of the connecting rod 6 away from the connecting seat 5 is movably connected to a connecting seat 2 7. The connecting seat 2 7 is fixedly connected to the outer wall of the mounting tube 4.

[0024] The two ends of the mounting tube 4 are fixedly connected with a driving box 8, and the outer walls on both sides of the driving box 8 are rotatably connected with driving wheels 9. Multiple driving wheels 9 are in conflict with the inner wall of the pipeline. A driving assembly for driving the driving wheels 9 to rotate is installed inside the driving box 8.

[0025] The drive assembly includes a transmission shaft 10 rotatably connected to the inner wall of the drive box 8. Both ends of the transmission shaft 10 pass through the drive box 8 and are fixedly connected to the axis of the two drive wheels 9. The outer wall of the transmission shaft 10 located inside the drive box 8 is fixedly connected to a bevel gear 11. The drive assembly also includes an electric motor 12 fixedly mounted on the inner walls of both ends of the mounting cylinder 4. The output shaft end of the electric motor 12 passes through the drive box 8 and is fixedly connected to a bevel gear 2 13. The bevel gear 2 13 is meshed with the bevel gear 11.

[0026] A battery 14 is installed inside the middle section of the mounting tube 4, and the battery 14 is electrically connected to the electric motor 12. A Wi-Fi communication module (not shown in the figure) is also installed on the inner wall of the mounting tube 4, and the Wi-Fi communication module is electrically connected to the electric motor 12. A Wi-Fi module is also installed on the remote control terminal. After the threading mechanism is placed into the pipeline, the Wi-Fi communication module in the mounting tube 4 will automatically connect to the external Wi-Fi network through the signal relay device. The remote control terminal is also connected to the same network and sends a start-up instruction to the electric motor 12 in the threading mechanism through special control software or application. This is a prior art and will not be elaborated on.

[0027] One end of the movable column 1 is fixedly connected to a towing hook 15 , and one end of the cable is tied to the towing hook 15 so as to be used for towing the cable.

[0028] The end of the movable column 1 away from the towing hook 15 is fixedly connected to the damping rod 16, and the end of the damping rod 16 away from the movable column 1 is fixedly connected to the rubber block 18. The outer wall of the damping rod 16 is sleeved with a buffer spring 17. The buffer spring 17 is located between the rubber block 18 and the movable column 1. When the threading mechanism reaches the other end of the pipeline movable column 1, the threading mechanism will hit the ground or wall. The rubber block 18, buffer spring 17 and damping rod 16 can play a buffering role to ensure that the parts of the threading mechanism will not be damaged.

[0029] The implementation principle of a wire threading mechanism for a fire-fighting project in the embodiment of the present application is as follows: when in use, one end of the cable is tied to the towing hook 15, and then the wire threading mechanism is placed in the pipe. The inner wall of the pipe squeezes the multiple driving wheels 9, so that the multiple driving wheels 9 drive the multiple installation cylinders 4 to retract inward. At this time, the multiple installation cylinders 4 squeeze the multiple connecting rods 6 inward, so that the multiple connecting rods 6 rotate, and then the multiple connecting rods 6 close to one end of the sliding sleeve 2 push the two sliding sleeves 2 close to each other, and the sliding sleeve 2 squeezes the inner support spring 3. The elastic force generated by the deformation of the inner support spring 3 acts in the opposite direction on the sliding sleeve 2, and the two sliding sleeves 2 slide away, and then push the multiple installation cylinders 4 outward through the multiple connecting rods 6. The multiple installation cylinders 4 expand and move, so that the multiple driving wheels 9 always contact the inner wall of the pipe, so that the multiple driving wheels 9 can adapt to pipes with different inner diameters.

[0030] After the threading mechanism enters the pipeline, the electric motor 12 is started by controlling the remote control terminal. The battery 14 is located in the electric motor 12 to supply power. When the electric motor 12 is started, its output shaft drives the bevel gear 2 13 to rotate, and the bevel gear 2 13 drives the bevel gear 1 11 meshing with it to rotate. The bevel gear 1 11 drives the transmission shaft 10 to rotate, and the transmission shaft 10 drives the drive wheel 9 to rotate. Multiple drive wheels 9 roll on the inner wall of the pipeline to drive the threading mechanism to move the cable and perform the threading operation.
