Description

Technical Field

[0001] The present application relates to the field of water conservancy construction, and in particular to a water conservancy project pipeline laying device and construction method. Background Art

[0002] In the process of water conservancy construction, the laying of pipelines is usually involved, that is, the water bodies in nature are drained by laying pipelines, so as to achieve the purpose of eliminating harm and promoting benefits.

[0003] At present, in the pipeline laying of water conservancy projects, trenches are usually dug first, and then the pipelines are laid in the trenches one by one after the trenches are supported. Finally, all the pipelines are connected. If the pipelines to be laid are large in diameter and heavy in weight, small cranes and other mechanical equipment are usually used to lift the pipelines, and then lift the pipelines to the target location, and finally lower the pipelines until all the pipelines are laid.

[0004] However, when using this lifting method, if the arm of the small crane is extended too long and the weight of the pipe to be lifted is too heavy, the torque generated by the crane when lifting the pipe will often be too large, which will put the small crane at risk of overturning. Summary of the Invention

[0005] In order to reduce the risk of overturning of a small crane, in a first aspect, the present application provides a water conservancy project pipeline laying device and a construction method.

[0006] The present application provides a water conservancy project pipeline laying device that adopts the following technical solution:

[0007] It includes a moving component, a frame and a hanging pipe component. The frame includes a horizontal beam, a vertical beam and a telescopic beam. There are two horizontal beams and they are parallel to each other. The number of vertical beams and telescopic beams corresponds to the number of horizontal beams. The vertical beam is connected to one end of the horizontal beam and is rotatably connected to the moving component. The vertical beam can rotate around its own axis on the moving component. The telescopic beam is installed at the end of the horizontal beam away from the vertical beam. The telescopic beam is installed at the end of the horizontal beam away from the vertical beam. A moving wheel is provided at the end of the telescopic beam away from the horizontal beam. The moving wheel can abut the ground. The hanging pipe component is installed between the two horizontal beams and can move along the length direction of the horizontal beam. The hanging pipe component is slid between the two horizontal beams for lifting pipes.

[0008] By adopting the above technical solution, when it is necessary to lay pipelines, first rotate the two vertical beams around their respective axes, so that the telescopic beam can be rotated out of the moving component along with the rotation of the cross beam. At this time, the telescopic beam connected to the cross beam can span the trench for laying pipelines. After the height of the telescopic beam is adjusted, the connection stability between the two telescopic beams is increased through the connection beam, and the first moving wheel on the telescopic beam can be abutted against the ground, so that the telescopic beam plays a role in supporting the cross beam. Furthermore, when the pipe lifting component is working, one end of the cross beam far from the vertical beam can have sufficient supporting force, so as to achieve the effect of reducing the risk of overturning of the moving component.

[0009] Optionally, a connection beam is arranged between the two telescopic beams, and the two ends of the connection beam are respectively connected to the two telescopic beams in a detachable manner.

[0010] By adopting the above technical solution, the rotation angles of the two vertical beams on the moving component can be fixed through the connection beam, so that the vertical beams will not rotate easily on the moving component, playing a role in improving stability.

[0011] Optionally, the pipe lifting component includes a first suspender, a second suspender, two winding machines and two moving parts. The two moving parts are respectively installed on the two cross beams and can slide along the length direction of the cross beams. The two winding machines are respectively connected to the two moving parts. Ropes are wound around the two winding machines. The first suspender is connected to the rope on one of the winding machines, the second suspender is connected to the rope on the other winding machine. An external thread is provided at one end of the first suspender far from the rope, and an internal thread is provided at one end of the second suspender far from the rope. The end of the first suspender and the end of the second suspender can be connected by means of thread fitting.

[0012] By adopting the above technical solution, the two moving parts can move freely along the length direction of the cross beam on the cross beam, which enables the winding machines respectively installed on the two moving parts to move freely along with the movement of the moving parts on the cross beam. At the same time, since the ropes wound around the two winding machines are respectively connected to the first suspender and the second suspender, the first suspender and the second suspender can move on the cross beam along with the movement of the moving parts. The external thread on the first suspender and the internal thread on the second suspender enable the first suspender and the second suspender to be connected by means of thread fitting, so that when the first suspender and the second suspender are connected to lift the pipeline, it can move along the length direction of the cross beam, realizing the function of moving the pipeline, and also enabling the first suspender and the second suspender to be disassembled, so that the vertical rod can rotate smoothly on the moving component.

[0013] Optionally, two limiting parts are arranged on the moving component. The first suspender can be connected to one of the limiting parts by means of thread fitting, and the second suspender can also be connected to the other limiting part by means of thread fitting.

[0014] By adopting the above technical solution, when the pipeline does not need to be moved, the first suspension rod and the second suspension rod are respectively connected to the limiting members on the moving assembly, so that the first suspension rod and the second suspension rod will not be in a suspended and shaking state, reducing the occurrence of injuries caused by the free swinging of the first suspension rod and the second suspension rod.

[0015] Optionally, the moving assembly includes a moving base, a driving member, a transmission belt, a driving walking wheel and a driven walking wheel. The two limiting members are respectively installed on the moving base. The driving member is installed on the base. The driving walking wheel and the driven walking wheel are both located below the moving base and rotatably connected to the moving base. The driving member is used to drive the driving walking wheel to rotate, and the transmission belt is used to realize the synchronous rotation of the driving walking wheel and the driven walking wheel.

[0016] By adopting the above technical solution, when the driving member is started, the driving walking wheel rotates accordingly. Since the transmission belt is wound around between the driving walking wheel and the driven walking wheel, therefore, with the rotation of the driving walking wheel, the driven walking wheel also rotates accordingly, thereby realizing the movement of the moving base on the ground.

[0017] Optionally, a pipe bin is further provided on the moving base. The cross-section of the pipe bin on the moving base is U-shaped, and openings are provided at both ends in the length direction of the pipe bin.

[0018] By adopting the above technical solution, a pipe bin is provided on the moving base, so that the pipeline to be laid can be stored in the pipe bin, and the pipeline can be directly moved from the pipe bin to the target position during laying, improving the efficiency of pipeline laying. The openings enable the pipe bin to accommodate pipelines of different lengths, playing a role in increasing the applicability of the pipe bin.

[0019] Optionally, a plurality of jacking members perpendicular to the moving base are evenly distributed on both sides of the moving base. The jacking members are installed on the moving base and can jack downward to the moving base.

[0020] By adopting the above technical solution, when pipeline laying needs to be carried out in special environments such as soft soil, the moving base can be jacked up by the jacking members, so that both the driving walking wheel and the driven walking wheel are separated from the ground. Then a crawler is wound around the driving walking wheel and the driven walking wheel. After that, the moving base is lowered by the jacking members and contacts the ground, so that the moving base can move on soft soil and other environments through the crawler.

[0021] Optionally, the telescopic beam includes a first telescopic beam connected to the cross beam and a second telescopic beam connected to the first moving wheel. The connecting beam is connected to the outer wall of the first telescopic beam. The first telescopic beam is sleeved on the second telescopic beam. The second telescopic beam can slide along the length direction of the first telescopic beam on the first telescopic beam. A locking member is provided at a position where the first telescopic beam is close to the second telescopic beam. The locking member is used to limit the sliding of the second telescopic beam on the first telescopic beam.

[0022] By adopting the above technical solution, when the telescopic beam is rotated out along with the rotation of the vertical beam, the extension position of the second telescopic beam on the first telescopic beam is adjusted, so that the first moving wheel on the second telescopic beam abuts against the ground, and then through the locking member, the extension distance of the second telescopic beam on the first telescopic beam is fixed, so that the total length between the second telescopic beam and the first telescopic beam is fixed, thereby playing a supporting role for the cross beam.

[0023] Optionally, a second moving wheel is further arranged below the second telescopic beam. The second moving wheel is on the same straight line as the second telescopic beam. When the first moving wheel abuts against the ground, the second moving wheel also abuts against the ground at the same time.

[0024] By adopting the above technical solution, both the first moving wheel and the second moving wheel abut against the ground, and the second moving wheel is on the same straight line as the second telescopic beam, so that there can be the support of the second moving wheel directly below the second telescopic beam, and the second moving wheel can share part of the load of the first moving wheel.

[0025] In a second aspect, the present application further provides a construction method for laying a water conservancy project pipeline, which adopts a water conservancy project pipeline laying device provided by the present application, and includes the following steps:

[0026] S100: Place the pipeline laying device on one side of the trench of the pipeline to be laid, and rotate the two vertical beams respectively, so that the two telescopic beams rotate from one side of the trench to the other side of the trench. At this time, the cross beam straddles the trench;

[0027] S200: Adjust the extension length of the telescopic beam so that the first moving wheel on the telescopic beam abuts against the ground;

[0028] S300: Start the pipe lifting assembly to lift the pipeline, move it above the trench on the cross beam, and then lower the pipeline into the trench to complete the laying of the current section of the pipeline;

[0029] S400: The pipe lifting assembly returns to its original position, and the moving assembly is driven to move to the next section along the trench, and the above step S300 is repeated to complete the laying of the pipeline in the next section.

[0030] In summary, the present application includes at least the following beneficial technical effects:

[0031] 1. By rotating the two vertical beams, the telescopic beam can be rotated out from the moving assembly along with the rotation of the cross beam. At this time, the telescopic beam connected to the cross beam can straddle the trench for laying the pipeline. After the height of the telescopic beam is adjusted, the first moving wheel on the telescopic beam can abut against the ground, so that the telescopic beam plays a supporting role for the cross beam, and thus when the pipe lifting assembly is working, the end of the cross beam far from the vertical beam can have sufficient supporting force, thereby achieving the effect of reducing the risk of overturning of the moving assembly;

[0032] 2. By arranging a jacking member on the moving base, the driving traveling wheels and the driven traveling wheels on the moving base can be equipped with crawlers on soft soil, thereby changing the moving mode of the moving base, achieving the effect of increasing the adaptability of the moving base when moving on different terrains; BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following will Figures 1-3 further describe the present application in detail.

[0038] Embodiment 1:

[0039] Embodiment 1 of the present application discloses a water conservancy project pipeline laying device. Referring to Figures 1-2 , it includes a moving assembly 1, a frame 2, and a pipe hanging assembly 3. Among them, the moving assembly 1 includes a moving base 15, a driving member 16, a transmission belt 17, a driving traveling wheel 18, and a driven traveling wheel 19.

[0040] The mobile base 15 is horizontally placed on the ground. The driving member 16 is a heavy-duty high-power motor and is installed on the upper surface of the mobile base 15. The driven traveling wheels 19 and the driving traveling wheels 18 are both located below the mobile base 15 and are rotatably connected to the mobile base 15. The driving member 16 is connected to the driving traveling wheels 18 by means of a belt drive, and the transmission belt 17 is used to connect the driving traveling wheels 18 and the driven traveling wheels 19 so that when the driving traveling wheels 18 rotate, they can drive the driven traveling wheels 19 to rotate together. This enables when the driving member 16 is started, the driving member 16 will drive the driving traveling wheels 18 to start rotating, and under the action of the transmission belt 17, the driven traveling wheels 19 will rotate together with the driving traveling wheels 18, thereby realizing the movement of the mobile base 15 on the ground.

[0041] Refer to Figure 1 and Figure 3 As shown in, a pipe bin 20 is also provided on the mobile base 15. The pipe bin 20 is used to store the pipes to be laid, thereby reducing the time required for transporting the pipes to improve the efficiency of laying the pipes. The length direction of the pipe bin 20 is consistent with the length direction of the mobile base 15, and openings 21 are respectively provided at both ends in the length direction of the pipe bin 20, which enables the pipe bin 20 to accommodate pipes of different lengths, thereby improving the applicability of the pipe bin 20 to pipes of different lengths.

[0042] Furthermore, a total of four lifting members 22 are provided on both sides in the length direction of the mobile base 15. The four lifting members 22 are evenly distributed. The lifting members 22 can be hydraulic cylinders or jacks. The lifting members 22 are vertically installed on the mobile base 15 and jack upward below the mobile base 15. This enables when laying pipes in special environments such as soft soil, etc., the mobile base 15 can be jacked up by the lifting members 22, so that both the driving traveling wheels 18 and the driven traveling wheels 19 are separated from the ground. Then, crawler belts are wound around the driving traveling wheels 18 and the driven traveling wheels 19. After that, the mobile base 15 is lowered by the lifting members 22 and contacts the ground, thereby enabling the mobile base 15 to move on soft soil and other environments through the crawler belts.

[0043] The frame body 2 includes vertical beams 5, cross beams 4 and telescopic beams 6. Among them, there are two vertical beams 5, two cross beams 4 and two telescopic beams 6. The two vertical beams 5 are respectively rotatably connected to both ends of the mobile base 15 and can rotate around their own axes on the mobile base 15. The two cross beams 4 are respectively fixedly connected to the two vertical beams 5, and the two telescopic beams 6 are respectively installed on two different cross beams 4. The telescopic beam 6 is vertically installed at the end of the cross beam 4. A first moving wheel 8 that can abut against the ground is connected to the end of the telescopic beam 6 away from the cross beam 4. When the vertical beam 5 does not rotate, the telescopic beam 6 is located on one side of the mobile base 15. When the vertical beam 5 rotates around its own axis, the telescopic beam 6 is in a position away from the mobile base 15, and finally a part of the cross beam 4 extends out of the mobile base 15 to cross the trench. At this time, the telescopic beam 6 supports the end of the cross beam 4 away from the vertical beam 5 on the other side of the trench.

[0044] The telescopic beam 6 includes a first telescopic beam 23 and a second telescopic beam 24. The first telescopic beam 23 is perpendicularly and fixedly connected to the cross beam 4. The first moving wheel 8 is installed at the position of the second telescopic beam 24 away from the first telescopic beam 23. The first telescopic beam 23 is sleeved on the second telescopic beam 24 and can slide along the length direction of the second telescopic beam 24. A locking member 25 is inserted through one end of the first telescopic beam 23 close to the second telescopic beam 24. The locking member 25 can be a screw. The axis of the locking member 25 is perpendicular to the length directions of the first telescopic beam 23 and the second telescopic beam 24, so that the extending length of the second telescopic beam 24 on the first telescopic beam 23 is fixed, further ensuring that the first telescopic beam 23 and the second telescopic beam 24 can support the cross beam 4 well.

[0045] Further, a connecting beam 7 is arranged between the two telescopic beams 6. Both ends of the connecting beam 7 are connected to the outer walls of the two telescopic beams 6 by means of bolts. The connecting beam 7 makes the rotation angle of the vertical beam 5 not easily change after rotation.

[0046] Furthermore, the first moving wheel 8 is arranged on the side wall of the second telescopic beam 24 away from the first telescopic beam 23, and a second moving wheel 26 is also arranged at the end of the support beam two. When the first moving wheel 8 abuts against the ground, the second moving wheel 26 also abuts against the ground at the same time. The second moving wheel 26 plays a role in sharing the load borne by the first moving wheel 8, thereby prolonging the service life of the first moving wheel 8.

[0047] If it is to move on soft soil, the first moving wheel 8 can also be made to be able to be used normally on soft soil by winding a crawler around the first moving wheel 8.

[0048] The pipe suspension assembly 3 includes two moving members 12, two winches 11, a first boom 9 and a second boom 10. Among them, the two winches 11 are respectively connected to the two moving members 12, and the two moving members 12 are respectively installed on two cross beams 4 and can slide along the length direction of the cross beam 4. The moving member 12 can be a hoisting motor, and thus can reciprocate along the length direction of the cross beam 4 on the cross beam 4 by means of remote control. A rope 13 is wound around the winch 11. The rope 13 is a steel wire rope with sufficient strength. The first boom 9 is connected to the rope 13 on one of the two winches 11, and the second boom 10 is connected to the rope 13 on the other winch 11. After the first boom 9 and the second boom 10 are respectively connected to the rope 13, they can rotate around their own axes, and the ends of the first boom 9 and the second boom 10 away from the rope 13 can be connected by means of thread fitting. This enables the first boom 9 and the second boom 10 to be in a separated state before use, so that the vertical rod can freely rotate on the moving base 15.

[0049] Furthermore, in order to prevent the first boom 9 and the second boom 10 from swaying randomly and causing harm to the staff around the moving base 15 when they are in a separated state, two limiting members 14 are respectively arranged on the moving base 15. The limiting members 14 are installed on the moving base 15 by means of fixed connection. The first boom 9 can be connected to one of the limiting members 14 by means of thread fitting, and the second boom 10 can be connected to the other limiting member 14 in the same way by means of thread matching. This enables the first boom 9 and the second boom 10 to be respectively connected to different limiting members 14 when not in use, so as to achieve the effect of fixing the positions of the first boom 9 and the second boom 10.

[0050] The implementation principle of Embodiment 1 of this application is as follows: First, move the movable base 15 filled with pipelines in the pipe bin 20 to the side of the trench. Then, remove the connecting beam 7 from the outer walls of the two telescopic beams I 23, and rotate the two vertical beams 5 respectively, so that the two cross beams 4 connected to the two vertical beams 5 are rotated out, so that the telescopic beam 6 at the end of the cross beam 4 straddles the trench. Adjust the extension length of the telescopic beam II 24 on the telescopic beam I 23 so that both the first moving wheel 8 and the second moving wheel 26 are in contact with the ground on one side of the trench. Then, unscrew the first suspension rod 9 and the second suspension rod 10 from the limiting member 14 respectively, and then insert the first suspension rod 9 and the second suspension rod 10 into both ends of the pipeline respectively and tighten them. After that, start the winch 11, and then lift the pipeline from the pipe bin 20. The moving member 12 starts to move on the cross beam 4, and then drives the lifted pipeline to move from a position far from the telescopic beam I 23 towards a position close to the telescopic beam I 23 until the pipeline is above the trench. Then, the winch 11 lowers the rope 13. When the bottom of the pipeline touches the bottom of the trench, the winch 11 still continues to lower the rope 13 for a certain distance so that the first suspension rod 9 and the second suspension rod 10 are not in contact with the inner wall of the pipeline, so as to unscrew the first suspension rod 9 and the second suspension rod 10 and lay the next pipeline.

[0051] When there is no need to lay pipelines, the telescopic beam 6 can be rotated back by rotating the vertical beam 5 again to reduce the occupied space of the pipeline laying device for water conservancy projects provided in this embodiment of the application.

[0052] Embodiment 2:

[0053] Embodiment 2 of this application provides a construction method for pipeline laying in water conservancy projects, which adopts the pipeline laying device for water conservancy projects provided in Embodiment 1 above. The steps are as follows:

[0054] S100: Place the pipeline laying device on one side of the trench of the pipeline to be laid, and rotate the two vertical beams 5 respectively, so that the two telescopic beams 6 are rotated from one side of the trench to the other side of the trench. At this time, the cross beam 4 straddles the trench;

[0055] S200: Adjust the extension length of the telescopic beam 6 so that the first moving wheel 8 on the telescopic beam 6 is in contact with the ground;

[0056] S300: Start the pipe lifting assembly 3 to lift the pipeline, move it above the trench on the cross beam 4, and then lower the pipeline into the trench to complete the pipeline laying of the current section;

[0057] S400: The pipe lifting assembly 3 returns to its original position, and the moving assembly 1 is driven to move along the trench to the next section, and repeat the above step S300 to complete the pipeline laying of the next section.

[0058] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
