[0002] Pipeline laying is one of the core components of water conservancy project construction. It involves multiple key steps and technical requirements to ensure the safe and efficient operation of the pipeline system. Furthermore, the pipelines used in construction play an important role in the diversion and water conveyance process, which can improve the utilization rate of water resources.

[0003] During pipeline laying, a device is needed to place and support the pipeline so that it can be accessed before it is laid in the soil. However, with existing devices, the pipeline moves on the roller assembly when it is supported, and the connectors at both ends of the roller assembly are welded to the side plate and the column, respectively. After long-term use, the roller assembly is prone to damage and becomes difficult to disassemble and assemble. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 One embodiment provided by this utility model:

[0025] A pipeline laying device for water conservancy engineering construction, comprising:

[0026] The main body includes a base frame 1. A crossbar 11 is installed on the surface of the base frame 1. A side plate 12 and a column 13 are fixedly connected to the surface of the crossbar 11. A roller assembly 14 is installed on the surface of the side plate 12 and the column 13. A connector 15 is fixedly connected to the surface of the roller assembly 14. The roller assembly 14 consists of a rotating shaft and a roller. Two sets of connectors 15 are provided and installed at both ends of the rotating shaft and respectively installed on the side plate 12 and the column 13. When laying the pipe, the pipe needs to be placed on the surface of the roller assembly 14 and pulled. When dragged, the roller assembly 14 can be rotated and rolled on the surface of the pipe.

[0027] The connecting mechanism includes a connecting hole 2, which is formed on the surface of the connector 15. A screw 21 is inserted into the surface of the connecting hole 2. A first nut 22 is threadedly connected to the surface of the screw 21. A threaded groove 23 is formed on the surface of the connector 15. An insertion hole 24 is formed on the surface of the first nut 22. A screw 25 is installed on the surface of the first nut 22. One end of each of the two sets of screws 21 is respectively installed and fixed on the surface of the side plate 12 and the column 13, while the other end is threadedly connected to the inner surface of the first nut 22, thereby realizing the installation of the roller assembly 14.

[0028] Furthermore, two sets of screws 21 are provided. One set of screws 21 is fixedly connected to the surface of the side plate 12, and the other set of screws 21 is fixedly connected to the surface of the column 13. The first nut 22 is abutted against the surface of the connector 15. Two sets of threaded grooves 23 and insertion holes 24 are provided. The screws 21 are connected to the surface of the connector 15 through the connecting hole 2. Thus, with the connection of the screws 21, the connecting hole 2, and the first nut 22, the two sets of connectors 15 can be fixedly installed on the surfaces of the side plate 12 and the column 13 respectively.

[0029] Furthermore, two sets of threaded grooves 23 are formed on both sides of the connector 15, and two sets of insertion holes 24 are formed on both sides of the first nut 22. The screw 25 is inserted into the surface of the insertion hole 24. One end of the screw 25 is threaded into the surface of the threaded groove 23, and the other end of the screw 25 is abutted into the surface of the first nut 22. The screw 25 can be installed through the threaded groove 23 and the insertion hole 24. With the connection of the screw 25, the insertion hole 24, and the threaded groove 23, the first nut 22 can be fixed to the surface of the connector 15 and rotated to limit its movement.

[0030] Furthermore, the base frame 1 is provided with an adjustment mechanism, which includes a plate 3. The plate 3 is installed on the surface of the crossbar 11. A sleeve 31 is installed on the surface of the plate 3. The plate 3 has a mounting hole 32. The sleeve 31 has a through hole 33. A mounting frame 34 is fixedly connected to the surface of the sleeve 31. A bolt 35 is installed on the surface of the sleeve 31. A second nut 36 is installed on the surface of the bolt 35. With the connection of the sleeve 31 and the two sets of plates 3, the base frame 1 and the crossbar 11 can be connected.

[0031] Furthermore, there are two sets of insert plates 3. One set of insert plates 3 is fixedly connected to the surface of the base frame 1, and the other set of insert plates 3 is fixedly connected to the surface of the crossbar 11. The two ends of the sleeve 31 are sleeved on the surface of the insert plates 3. There are two insert plates 3 in each set, and they are respectively set on both sides of the base frame 1 and the crossbar 11.

[0032] Furthermore, there are two sets of mounting holes 32 and through holes 33. The two sets of mounting holes 32 are opened on both sides of the insert plate 3, and the two sets of through holes 33 are opened on both sides of the sleeve 31. The diameter of the mounting holes 32 and the diameter of the through holes 33 are the same. The bolts 35 can be installed through the mounting holes 32 and the through holes 33. The through holes 33 are distributed in a linear array on the surface of the sleeve 31 to adjust the spacing between the two sets of insert plates 3, thereby adjusting the height of the roller assembly 14.

[0033] Furthermore, the surface of the mounting frame 34 is hexagonal, and the bolt 35 is inserted into the surface of the mounting hole 32 and the through hole 33. One end of the bolt 35 is engaged with the inner surface of the mounting frame 34, and the other end of the bolt 35 is threaded to the inner surface of the second nut 36. The second nut 36 is abutted against the surface of the sleeve 31. The mounting frame 34 can limit the bolt 35 and prevent the bolt 35 from rotating when the second nut 36 is tightened. The bolt 35 passes through the mounting hole 32 and the through hole 33 through the surface of the insert plate 3 and the sleeve 31. With the connection of the bolt 35 and the second nut 36, the insert plate 3 and the sleeve 31 can be fixed together.

[0034] Working principle: When replacing the roller assembly 14, first align the connecting hole 2 on the connector 15 with the screw 21 and fit it on its surface. Then, place the two sets of connectors 15 against the side plate 12 and the column 13 respectively. Next, connect the first nut 22 to the screw 21 by thread and tighten it against the surface of the connector 15. At this time, the thread groove 23 and the hole 24 are aligned. Then, insert the screw 25 into the hole 24 and rotate the screw 25 with a Phillips screwdriver so that one end of the screw 25 is connected to the thread groove 23 by thread and the other end abuts against the surface of the first nut 22, thereby realizing the installation of the roller assembly 14.

[0035] When adjusting the height of the laid pipe, first pull the two sets of insert plates 3 to slide them on the inner surface of the sleeve 31 to adjust the alignment of the mounting hole 32 and the through hole 33 at different positions. When the roller assembly 14 is placed at the appropriate height, insert the bolt 35 from the mounting frame 34 side into the mounting hole 32 and the through hole 33. Then, connect the second nut 36 to one end of the bolt 35 by thread and tighten it against the sleeve 31. The other end of the bolt 35 is stuck inside the mounting frame 34 and against the sleeve 31, thereby completing the height adjustment of the roller assembly 14.
