It includes foundation engineering construction, main structure construction, roofing engineering construction, and decoration engineering construction. At present, various water pipes and gas pipes need to be installed in construction, and welding, cutting, and pipe simmering are often encountered.

At the same time, when cutting the pipes, the operator fixes the pipes with his hands or feet, which poses certain safety hazards.

[0003] Chinese utility model patent CN206911969U discloses a pipe mouth regulator for construction pipelines, including a lower roundness adjustment port, a fixing bolt, a manual wrench and an upper roundness adjustment port, a pipe placement platform is installed above the lower roundness adjustment port, a dynamic pressure plate is installed above the pipe placement platform, a fixing bolt is installed above the dynamic pressure plate, an adjustment bias pressure plate is arranged above the fixing bolt, a support platform is installed above the adjustment bias pressure plate, a transmission thread is installed above the support platform, a manual wrench is connected above the transmission thread, a thread protector is installed below the manual wrench, a hydraulic spring is installed below the thread protector, a fixed platform is connected below the hydraulic spring, an upper roundness adjustment port is installed above the fixed platform, and a small hydraulic cylinder is installed above the upper roundness adjustment port. The pipe mouth correction effect of the regulator is poor and the function is single.

The first telescopic rod 503 is arranged along the radial direction of the positioning ring plate 501, and a plurality of first telescopic rods 503 are evenly arranged on the positioning ring plate 501, so that the correction plate 504 can fit on the outer wall of the pipe.

[0038] Please see attached Figure 1 To Attachment Figure 8 , the use method and working principle of the present invention are:

[0039] Remove the adjustment component 5 through the positioning slide plate 406 and the positioning groove 505, insert the two pipes to be clamped into the two groups of clamping components respectively, use a hexagonal tool to insert into the hexagonal groove 3062 and rotate it, so that the rotating block 306 drives the second bevel gear 3061 to rotate and synchronously transmit the bevel gear ring 307, so that the bevel gear ring 307 transmits several first bevel gears 308 to rotate synchronously, and because the first ball nut is embedded in the moving ring assembly and cannot move, the rotation of the first bevel gear 308 is converted into the axial linear motion of the first ball screw 305 through the thread, so that the clamping plate 309 is pushed inward and pressed against the outer wall of the pipe, and several clamping plates 309 simultaneously circumferentially embrace the outer wall of the pipe, so as to accurately position the pipe.

[0040] The stepper motor 402 is powered on and starts to drive a second ball screw 401 connected thereto to rotate synchronously, the gear 404 on the second ball screw 401 rotates synchronously and drives the outer gear ring 405 to rotate synchronously, the outer gear ring 405 drives several gears 404 to rotate synchronously, thereby driving several second ball screws 401 to rotate synchronously. Since the second ball nut 407 is embedded in the moving block 3011 and cannot move, the rotation of the second ball screw 401 is converted into the axial linear motion of the second ball nut 407 through the thread, so that the second ball nut 407 drives the moving ring 301 to move closer to each other along the axial direction of the second ball screw 401, so that the two pipes are docked together. The positioning plate 1, the positioning ring 2 and the clamping assembly 3 of the pipe clamping mechanism have the same structure, which can ensure the accuracy of the docking of the two pipes.

[0041] After the two pipes are butted, the adjustment assembly 5 is inserted into the second protective shell 403 through the positioning slide plate 406 and the positioning slide groove 505, and the correction plate 504 is pressed against the outer wall of the pipe through the synchronous extension and contraction of a plurality of first telescopic rods 503, and the correction roller 509 is pressed against the inner wall of the pipe through the synchronous extension and contraction of a plurality of second telescopic rods 507. The axial degree of the pipe is further improved by pressing the inner and outer sides, thereby improving the accuracy of pipe butt connection. Preferably, the second telescopic rod 507 and the second telescopic rod 507 can both adopt existing telescopic rod structures such as electric telescopic rods, pneumatic telescopic rods or hydraulic telescopic rods, and their synchronous extension and contraction can be controlled by a control device, which will not be repeated here. The extension and contraction have high synchronization and accuracy, thereby ensuring the accuracy of pipe correction.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
