[0051] Furthermore, in a preferred embodiment, different diameter electric wrenches 3 can be selected to adapt to pipes of different diameters.

[0052] Furthermore, in a preferred embodiment, the first arc-shaped body 36 is provided with a locking tooth 363, and the second arc-shaped body 37 is provided with a locking tooth 373, so that the pipe 6 to be installed can be locked by the locking tooth 363 and the locking tooth 373.

When the installation port of the pipe to be installed 6 and the installation port of the installed pipe 5 are close together, the vision detection module 21 will continuously send signals to the first receiving module as a reminder. If the installation port of the pipe to be installed 6 and the installation port of the installed pipe 5 are misaligned, the vision detection module 21 will send a misalignment signal to the first receiving module, and the first control module will then control the moving structure 1 and the electric wrench 3 to stop working.

Near the pipe to be installed 6, the radial wheels 42 are higher than the axial wheels 41, i.e., the radial wheels 42 are in contact with the pipe to be installed 6. The radial wheels 42 enable the pipe to be installed 6 to rotate easily about its own axis, and the axial wheels 41 enable the pipe to be installed 6 to move axially, facilitating the gradual approach of the pipe to be installed 6 to the already installed pipe 5.

[0057] Furthermore, in a preferred embodiment, the pipe connection auxiliary device further includes a second control module, which is a main control device and can be a mobile device or a PC.

If an error occurs, the first control module will also promptly send a signal to the second control module.

[0058] Furthermore, in a preferred embodiment, by using a pipe connection auxiliary device, it is possible to facilitate the mutual auxiliary connection of various pipes, such as drinking water pipes, drainage water supply pipes, etc., thereby improving the applicability of this embodiment.

[0059] In addition to the above, the present invention also has the following usage methods:

[0060] Please continue reading Figures 1 to 5 As shown, step one: use the hand wrench 2 to radially engage the installed pipe 5.

[0061] Step 2: Insert the mounting block of manual wrench 2 into the mounting slot at one end of base 11.

[0062] Step 3: Screw one end of the threaded connector 7 into the installation port of the installed pipe 5.

[0063] Step 4: Open the first arc-shaped outer shell 34 and the second arc-shaped outer shell 35 of the electric wrench 3, so that the first arc-shaped body 36 and the second arc-shaped body 37 are separated, and the electric wrench 3 is radially clamped to the pipe 6 to be installed. Then, the first arc-shaped outer shell 34 and the second arc-shaped outer shell 35 are merged together, so that the clamping teeth 363 of the first arc-shaped body 36 and the clamping teeth 373 of the second arc-shaped body 37 can clamp the pipe 6 to be installed.

[0064] Step 5: Insert the mounting block of the electric wrench 4 into the mounting slot of the movable plate 14.

[0065] Step 6: Place several support devices 4 at intervals at the bottom of the pipe 6 to be installed.

[0066] Step 7: The first control module issues a working command, the third receiving module of the electric wrench 3 receives the working command, the drive source 38 of the electric wrench 3 works, driving the pipe 6 to be installed to rotate around itself; at the same time, the second receiving module of the moving structure 1 receives the working command, the drive source of the moving structure 1 causes the lead screw 12 to rotate around itself, thereby driving the moving plate 14 and the electric wrench 3 to move towards the manual wrench 2, so that the pipe 6 to be installed gradually rotates and is screwed into the installation port (the other end of the threaded connector 7) of the installed pipe 5.

[0067] Step 8: When the installation port of the pipe to be installed 6 is close to the installation port of the installed pipe 5, the visual detection module 21 will continuously send signals to the first receiving module to inform that the two are gradually getting closer and closer to each other.

[0068] Step Nine: When the pipe to be installed 6 is screwed into the installation port (the other end of the threaded connector 7) of the installed pipe 5, the torque sensor 31 detects that the torque has reached the preset torque. The torque sensor 31 sends a torque command to the second transmitting module, the first receiving module receives the command, the first control module sends a stop command through the first transmitting module, and the third receiving module receives the command, thereby controlling the drive source 38 to stop and the electric wrench 3 to stop working. At the same time, the second receiving module of the moving structure 1 receives the command, and the lead screw 12 and the moving plate 14 stop.

[0069] Step 10: Remove the manual wrench 2 radially from the installed pipe 5, remove the electric wrench 3 radially from the pipe 6 to be installed, and remove the support device 4 from the bottom of the pipe 6 to be installed.

[0070] In addition to the above, the present invention also has the following determination method:

[0071] Please continue reading Figures 1 to 5 As shown, the first control module sends a working or stopping command to the moving structure 1 through the first sending module. The second receiving module of the driving source of the moving structure 1 receives the working or stopping command, and then the driving source causes the lead screw 12 to rotate or stop around itself, thereby causing the moving plate 14 to move closer to the other end, or to move the moving plate 14 away from the reset, or to stop the moving plate 14.

[0072] The first control module sends a work or stop command to the electric wrench 3 through the first sending module. The third receiving module of the electric wrench 3 receives the work or stop command, thereby causing the drive source 38 of the electric wrench 3 to work or stop.

[0073] When the torque sensor 31 detects that the torque has reached the preset torque, it sends a command indicating that the preset torque has been reached through the second transmitting module. The first receiving module receives the command, and the first control module sends a stop command through the first transmitting module. The third receiving module receives the stop command, thereby controlling the drive source 38 to stop, and the electric wrench 3 to stop working. At the same time, the second receiving module also receives the stop command, and the moving plate 14 stops moving.

[0074] When the installation port of the pipe to be installed 6 is close to and fits into the installation port of the already installed pipe 5, the visual detection module 21 will continuously send signals to the first receiving module to provide a reminder to the first control module.

[0075] When the installation port of the pipe to be installed 6 is misaligned with the installation port of the already installed pipe 5, the visual detection module 21 will send a misalignment signal to the first receiving module. The first receiving module receives the command, and the first control module sends a stop command through the first sending module. The third receiving module receives the stop command, thereby controlling the drive source 38 to stop, and the electric wrench 3 to stop working. At the same time, the second receiving module also receives the stop command, and the moving plate 14 stops moving.

[0076] The second control module is signal-connected to the first control module. The first control module transmits real-time lower-level status, such as working status, stop status, and misalignment status, to the second control module. The second control module can send overall working or stopping commands, which are then issued by the first control module.
