[0034] The power unit is located at the rear of the frame 1 and at the bottom of the movable height adjustment component 6, and is used to synchronously drive the movable height adjustment component 6.

[0035] In this embodiment, as Figure 1 As shown, the support component 7 can support and limit the bottom of pipes of various diameters, the top pressing component 8 can press and limit the top of pipes of various diameters, and the power component can synchronously drive the movable height adjustment component 6 to raise and lower, so that the height of the pipes on both sides can be kept consistent. The first servo motor 5 drives the bidirectional screw 4 to rotate, which can adjust the distance between the movable height adjustment components 6, so that the pipes on both sides can be brought closer together and then connected.

[0036] Example 2

[0037] The difference from Embodiment 1 is that this embodiment discloses a movable height adjustment assembly 6, a support assembly 7, and a top-pressing assembly 8:

[0038] The movable height adjustment assembly 6 includes a slider 12 and a slide rail 13. The slider 12 is slidably connected to the slide groove 3 and is threadedly connected to one side of the corresponding bidirectional screw 4. The slide rail 13 is fixedly connected to the rear end of the slider 12, and a lifting screw 14 is rotatably connected inside the slide rail 13.

[0039] The support assembly 7 includes a support plate 20 and a V-shaped frame 21.

Fixed seats 23 are fixedly connected to both sides of the upper end of the V-shaped frame 21.

[0040] The top-pressure assembly 8 includes an arc-shaped plate 24 and a mounting base 28. Fixing blocks 25 are fixedly connected to both sides of the bottom end of the arc-shaped plate 24. The fixing blocks 25 are connected to the corresponding mounting bases 23 via pins. The mounting base 28 is located at the middle of the lower end of the arc-shaped plate 24. A roller 31 is rotatably connected inside the mounting base 28. An adjusting screw 29 is rotatably connected to the middle of the upper end of the mounting base 28. An adjusting knob 32 is fixedly connected to the upper end of the adjusting screw 29. Limiting rods 30 are fixedly connected to both sides of the upper end of the mounting base 28.

[0041] In this embodiment, as Figures 3-5 As shown, the pipe is placed on the V-shaped frame 21. The support rollers 22 can support and limit the bottom of the pipe on both sides. The fixing blocks 25 on both sides of the bottom of the arc plate 24 are engaged with the corresponding fixing seats 23 and fixed with pins. Rotating the adjustment knob 32 drives the adjustment screw 29 to rotate. The adjustment screw 29 engages with the internal threaded pipe 26, which can drive the mounting seat 28 to move along the limiting pipe 27 through the limiting rod 30, so that the roller 31 contacts the upper end of the pipe and presses and limits the upper end of the pipe, thereby allowing the pipe to be... The limit position ensures that the center lines of the pipes on both sides are aligned. The rotation of the lifting screw 14 can drive the support assembly 7 to move along the slide rail 13 via the support plate 20, thereby adjusting the height of the pipes and facilitating the hot-melt operation by construction personnel. The rotation of the bidirectional screw 4 can drive the movable height adjustment assembly 6 to move closer to or further away from the slide groove 3 via the slider 12. Furthermore, by pushing the pipes, the pipes can move along the support roller 22 and roller 31, thereby adjusting the spacing between the pipes and facilitating pipe docking.

[0042] Example 3

[0043] The difference from Embodiment 1 is that this embodiment discloses a power assembly:

[0044] The power assembly includes a drive shaft 9, a connecting seat 16 and a first gear 15. The drive shaft 9 is rotatably connected to the rear side of the frame 1. Several limiting grooves 10 are opened on the outer side of the drive shaft 9. A second servo motor 11 is fixedly connected to one end of the rear side of the frame 1.

After the end face gear 19 meshes with the first gear 15, it can drive the lifting screw 14 to rotate.

[0047] The working principle of this utility model is as follows:

[0048] The support component 7 can support and limit the bottom of pipes of various diameters, and the top pressing component 8 can press and limit the top of pipes of various diameters. Specifically, the pipe is placed on the V-shaped frame 21, and the support roller 22 can support and limit the bottom of the pipe on both sides. The fixing blocks 25 on both sides of the bottom of the arc plate 24 are locked with the corresponding fixing seats 23 and fixed with pins. Rotating the adjustment knob 32 drives the adjustment screw 29 to rotate. The adjustment screw 29 engages with the internal threaded pipe 26, which can drive the mounting seat 28 to move along the limiting pipe 27 through the limiting rod 30, so that the roller 31 contacts the top of the pipe and presses and limits the top of the pipe, thereby limiting the pipe and making the center lines of the pipes on both sides in a straight line.

[0049] The set power component can synchronously drive the movable height adjustment component 6 to raise and lower, so that the height of the pipes on both sides can be kept consistent. Specifically, the set second servo motor 11 drives the transmission shaft 9 to rotate. Through the cooperation of the limit block 18 and the limit groove 10, it can drive the end face gear 19 on the hollow rotating shaft 17 to rotate. After the end face gear 19 meshes with the first gear 15, it can drive the lifting screw 14 to rotate. The rotation of the set lifting screw 14 can drive the support component 7 to move along the slide rail 13 through the support plate 20, thereby adjusting the height of the pipe and facilitating the hot melt operation by the construction personnel.

[0050] The first servo motor 5 drives the bidirectional screw 4 to rotate, which can adjust the spacing between the movable height adjustment components 6, thereby bringing the pipes on both sides closer together and allowing them to be connected. Specifically, the rotation of the bidirectional screw 4 can drive the movable height adjustment components 6 to move closer or further away from each other along the slide groove 3 via the slider 12, and by pushing the pipes, the pipes can move along the support roller 22 and the roller 31, thereby adjusting the spacing between the pipes and facilitating pipe connection.
