Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0059] In this embodiment, when the worker is working, he puts the pipe between the first clamp block 101 and the second clamp block 102, and then starts the driving mechanism 103 to make the second clamp block 102 close to the first clamp block 101, so that the pipe is clamped by the first clamp block 101 and the second clamp block 102, and then the worker takes the clamping assembly 1 to connect with the pipe in the construction area for full welding. This effectively avoids the unstable clamping of the pipe during welding, makes the pipe welding more firm, and avoids water leakage.

[0060] In this embodiment, the driving mechanism 103 may be driven by: gear 1035 and rack 1034 , motor or pulley.

[0061] In this embodiment, the clamping process between the first clamping block 101 and the second clamping block 102 can also be in the following form: a lead screw is used, the lead screw has a left-handed threaded portion and a right-handed threaded portion, the first clamping block 101 is threadedly connected to the left-handed threaded portion, and the second clamping block 102 is threadedly connected to the right-handed threaded portion, and then a motor is used to drive the lead screw to rotate, so that the first clamping block 101 and the second clamping block 102 are close to or away from each other, thereby clamping the pipe.

[0062] Furthermore, the driving mechanism 103 includes: a fixed frame 1031, having a first slide groove 1032, and the first clamping block 101 is set on the fixed frame 1031; a sliding rod 1033, which is set on one side of the second clamping block 102, and the sliding rod 1033 slides in the first slide groove 1032; a rack 1034, which is set at the lower end of the sliding rod 1033; a gear 1035, which is rotatably set on the fixed frame 1031, and the gear 1035 is meshed and connected with the rack 1034.

[0063] In this embodiment, the slide bar 1033 has a sliding end, and the sliding end slides in the first slide groove 1032; the gear 1035 is driven by a motor; and the rack 1034 is arranged at the lower end of the sliding end of the slide bar 1033. When a worker wants to clamp the pipe placed between the first clamping block 101 and the second clamping block 102, the gear 1035 is first driven to rotate. Since the gear 1035 and the rack 1034 are meshed and connected, the rack 1034 moves with the gear 1035, so that the second clamping block 102 approaches the first clamping block 101, and the sliding distance of the second clamping block 102 is the length of the first slide groove 1032. Pipes of different diameters can be clamped, which improves the application range of the device.

[0064] Furthermore, the first clamping block 101 and the second clamping block 102 are both arc-shaped clamping plates.

[0065] In this embodiment, the first clamping block 101 and the second clamping block 102 are arc-shaped clamping plates adapted to the arc-shaped outer wall of the pipe.

[0066] Furthermore, it also includes: a lifting component 2, a clamping component 1 is arranged above the lifting component 2, and the lifting component 2 includes: a support rod 201, the support rod 201 has a first inner cavity 202, and both sides of the support rod 201 are provided with a second slide groove 2021 connected to the first inner cavity 202; a first slider 203 is arranged in the first inner cavity 202 for sliding along the height direction; the clamping component 1 follows the movement of the first slider 203.

[0067] In this embodiment, the clamping assembly 1 is arranged above the first slider 203, and the first slider 203 slides up and down in the first inner cavity 202 along the height direction. When workers need to weld pipes at different heights, they only need to slide the first slider 203 up and down to meet the processing requirements. This improves the scope of application of the device and saves workers' construction time.

[0070] In this embodiment, when the two second sliders 2043 slide relative to each other in the second inner cavity 2042, the transmission rod 2044 provides the first slider 203 with an upward or downward sliding force, causing the first slider 203 to slide up and down along the height direction in the first inner cavity 202, so that the lifting device completes the height adjustment of the clamping assembly 1.

[0071] In this embodiment, the driving form of the relative sliding of the two second sliders 2043 can be: the two second sliders 2043 can be driven to slide relative to each other by two hydraulic cylinders or air cylinders; or the relative sliding of the two second sliders 2043 is driven by the gear 1035 and the rack 1034.

[0072] Furthermore, the transmission device 204 also includes: a forward and reverse screw 2045, which is rotatably arranged in the second inner cavity 2042, and the two second sliders 2043 are both threadedly connected to the forward and reverse screw 2045; and a reduction motor 2046, which drives the forward and reverse screw 2045 to rotate.

[0073] In this embodiment, the forward and reverse screw 2045 has a left-handed threaded portion and a right-handed threaded portion, and a second slider 2043 is threadedly connected to the left-handed threaded portion and the right-handed threaded portion. When the reduction motor 2046 drives the forward and reverse screw 2045 to rotate, the two second sliders 2043 approach or move away from each other, causing the first slider 203 to slide up and down in the first inner cavity 202.

The scope of application of the device is expanded.

[0076] Furthermore, it also includes: a second fixed seat 3, which is arranged above the telescopic end 2051, and the second fixed seat 3 moves up and down following the telescopic end 2051, and the second fixed seat 3 has a third inner cavity 301 and a third slide groove 302 opened at the upper end of the second fixed seat 3; a third slider 4, which is slidably arranged in the third slide groove 302, and the fixed frame 1031 is arranged on the third slider 4; a threaded rod 5, which is rotatably arranged in the third inner cavity 301, and the threaded rod 5 is threadedly connected to the third slider 4; a positioning motor 6, and the positioning motor 6 drives the threaded rod 5 to rotate; a clamping assembly 1 is arranged on the third slider 4, and the clamping assembly 1 slides following the third slider 4.

At this time, it is necessary to move the pipeline on one side to enable the pipeline to be docked. At this time, it is necessary to start the positioning motor 6 to make the third slider 4 slide in the third slide groove 302, so that the clamping assembly 1 is close to or away from the pipeline in the construction area, so that the pipeline and the pipeline in the construction area are docked. Moving the pipeline is more convenient and labor-saving, which ensures the accuracy of welding.
