[0022] Embodiment 1:

[0023] like Figures 1 to 5 A pipeline installation butt joint tool comprises two sets of pipeline clamps respectively fixed on two pipelines 50. The pipeline 50 is provided with a pipeline flange 51 for butt joint.

[0024] Each set of pipe clamps includes two first U-shaped clamps 10, that is, there are four first U-shaped clamps 10. The first U-shaped clamps are provided with symmetrical first wing plates 11 on both sides, and the first wing plates are provided with symmetrical first fixing holes 12. The first U-shaped clamps are fixed to the pipe by first bolts 13 passing through the first fixing holes. In fact, the pipe clamps can adopt components of universal structure.

[0025] Each set of pipe clamps is provided with a hook connector 14 on both sides, and there are four hook connectors 14 in total, and one hook connector 14 is installed on each first U-shaped clamp 10. The hook connector 14 is a groove-shaped structure, and the hook connector is provided with a connecting groove 16, a hook hole 15 and a hook connector fixing hole 17.

[0026] The hook connector 14 is mounted on the outer side 11a of the first wing plate, and the connecting groove 16 is embedded in the first wing plate of the first U-shaped clamp. The first bolt 13 fixes the first U-shaped clamp while passing through the hook connector fixing hole 17 to fix the hook connector on the first wing plate 11, and the hook hole 15 protrudes out of the pipe clamp (that is, protrudes out of the first wing plate 11 of the first U-shaped clamp).

[0027] Two sets of flower basket bolts 40 are arranged between the two sets of pipeline clamps, and the two sets of flower basket bolts are respectively connected to the two sets of pipeline clamps at both ends of the pipeline clamps. Bolt hooks 41 are arranged at both ends of the flower basket bolts, and the bolt hooks are hooked into the hook holes 15 to connect the two sets of pipeline clamps.

[0028] When in use, two sets of pipe clamps are fixed on two pipes to be butted, and the hook connector 14 is also fixed on the fixing clamp while fixing the pipe clamp. In this way, four hook connectors 14 are arranged in pairs on both sides of the two pipes. When fixing the pipe clamp, it is important to make the bolt holes 52 on the two pipe flanges 51 correspond to each other. Figure 3 Then, the two pipes 50 are butt-jointed so that the flanges of the two pipes are as close as possible, and the bolt hooks 41 of the two sets of turnbuckle bolts 40 are hooked into the hook holes 15 of the hook joint, as shown. Figure 1 The situation shown. Then, the turnbuckle bolts are retracted to make the two pipe flanges 51 butt-jointed (i.e., the end faces of the two pipe flanges are in contact or very close). In this process, since the turnbuckle bolts and the hook joints are connected by bolt hooks, the pipe flanges can be properly rotated to make the bolt holes 52 on the two pipe flanges align with each other. Then, the pipe connecting bolts 53 are used to connect and fix the two pipe flanges at the two bolt holes avoiding the turnbuckle bolts, as shown in FIG. Figure 4 After that, remove the two sets of pipe clamps and turnbuckle bolts, and complete the installation and tightening of other pipe connection bolts 53, as shown in FIG. Figure 5 shown.

[0029] The bolt fixing described in this embodiment is fixing by the cooperation of bolts and nuts.

[0030] The utility model uses a basket bolt and a U-shaped clamp to dock and correct the pipe joints, which saves a lot of time and manpower for manual docking of pipes, helps to accurately correct the docking of pipe joints, and has a simple structure and is easy to carry. The tool has few structural parts, and the pipe clamps and basket bolts can use standardized universal parts. Different U-shaped clamps can be replaced according to different pipes to adapt to various types of pipe docking. The tool is easy to use and easy to use in coal mines.

[0031] Embodiment 2:

[0032] like Figure 6 , Figure 7 , a pipe installation docking tool. This embodiment is a structural improvement of the first embodiment.

[0033] This embodiment improves the structure of the pipeline clamp. Each set of pipeline clamps includes two second U-shaped clamps 20, and the two sets of pipeline clamps have a total of four second U-shaped clamps 20.

[0034] The second U-shaped clamp 20 is provided with a second long wing plate 21 and a second short wing plate 22 on both sides respectively. The second long wing plate and the second short wing plate are provided with symmetrical second fixing holes 24. The length L1 of the second long wing plate is greater than the length L2 of the second short wing plate. The second long wing plate is provided with a second hook hole 23. The second hook hole 23 is arranged on the side of the second fixing hole 24 away from the pipe.

[0035] The two second U-shaped clamps 20 of each set of pipe clamps are fixed to the pipe 50 by bolts 25, the long wing plate of one second U-shaped clamp is butted with the short wing plate of the other second U-shaped clamp, and the long wing plates of the two second U-shaped clamps are symmetrically arranged on both sides of the pipe.

[0036] Similar to the first embodiment, bolt hooks 41 are provided at both ends of the turnbuckle bolt 40 , and the bolt hooks 41 are hooked into the second hook holes 23 to connect the two sets of pipe clamps.

[0037] Compared with the first embodiment, the hook holes of the two turnbuckle bolts are integrated on the U-shaped clamp in this embodiment, eliminating the hook joint. During assembly, it is no longer necessary to connect and fix the hook joint, which further facilitates use and operation.

[0038] Embodiment three:

[0039] like Figure 8 , Fig.10 , a pipe installation docking tool. This embodiment is a structural replacement of the first embodiment.

[0040] In this embodiment, each set of pipe clamps includes a first U-shaped clamp 10 and a third U-shaped clamp 30. Similar to the first embodiment, the first U-shaped clamp has symmetrical first wing plates 11 on both sides, and the first wing plates have symmetrical first fixing holes 12.

[0041] The third U-shaped clamp 30 is provided with symmetrical third wing plates 31 on both sides, and the third wing plates are provided with third fixing holes 32 corresponding to the first fixing holes. The length L3 of the third wing plate 31 is greater than the length L4 of the first wing plate 11, and the end of the third wing plate is provided with a basket bolt connecting shaft 33, which extends out of the third wing plate 31, and the axis of the basket bolt connecting shaft 33 is perpendicular to the pipe 50. The basket bolt connecting shaft 33 is welded to the third wing plate 31.

[0042] The two ends of the turnbuckle bolt 40 are provided with turnbuckle bolt connection holes 42, and the two ends of the turnbuckle bolt are hinged with the turnbuckle bolt connection shaft 33. The turnbuckle bolt connection shaft is also provided with a pin hole 34, and the turnbuckle bolt 40 is assembled with the third U-shaped clamp 30 through a cylindrical pin 35 and a flat washer 36, such as Fig. 9 shown.

[0043] In this embodiment, the third U-shaped clamp 30 and the turnbuckle bolt 40 are assembled into one component.

[0044] When in use, first move the flanges of the two pipes to a close position, then use the assembled third U-shaped clamp 30 and basket bolt 40 assembly to buckle the two third U-shaped clamps 30 on the two pipes respectively, and then use the first U-shaped clamp 10 to fix the third U-shaped clamp 30. It is no longer necessary to use a hook to connect the pipe clamp and the basket bolt, which simplifies the operation. Since the axis of the basket bolt connecting shaft 33 is perpendicular to the pipe 50, the pipe flange can be properly rotated so that the bolt holes 52 on the two pipe flanges are aligned with each other.

[0045] In the above embodiment, only the flange connection mode of the pipeline is exemplified, and the technical solution of the utility model can also be applied to the butt joint operation of pipelines with other connection modes. For butt joint of pipelines with different diameters, pipeline clamps of different specifications can be used.
