[0002] The main functions of valley steep slope pipeline laying and transportation include improving the transportation efficiency of oil and gas resources, reducing transportation costs, ensuring transportation safety, and adapting to construction needs under special geographical conditions.

[0003] In areas with low slopes, pipe laying machines are usually used to transport and lay pipes. However, for the high and steep slopes of U-shaped valleys, the terrain along the route is undulating, the road is rugged, the slope angle is large, and the slope is long, making it difficult for large equipment to be deployed. The traditional method uses manual transportation, but when transporting large-diameter heavy steel pipes for laying pipes, it is difficult to carry out construction by manpower due to the large volume and weight of the pipes.

[0004] At the same time, the existing steep slope sections usually adopt the method of pipe transportation and laying, which is to dig the trench after measuring and laying out the lines, and then lower the pipeline along the trench by a winch. However, this method is difficult to align the pipelines and is not convenient for pipeline welding. At the same time, the semi-buried form of the pipeline is not conducive to later maintenance.

[0005] Therefore, there is an urgent need for a large-diameter heavy-duty steel pipe transportation device suitable for the high and steep slope sections of U-shaped valleys to improve transportation efficiency and facilitate pipeline adjustment. Summary of the invention

DETAILED DESCRIPTION

[0021] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0022] Example 1 like Figure 1-Figure 7 As shown, a large-diameter heavy-duty steel pipe transportation device suitable for high and steep slope sections of U-shaped valleys is provided, including a pipeline pier 1, a track 2, a transportation component 3 and a winch 4.

[0023] Specific as Figure 1 and Figure 2 As shown, in the high and steep slope section of the U-shaped valley, the pipeline piers 1 are arranged in advance according to the laying direction of the pipeline 7. The pipeline piers 1 are arranged at intervals along the contour of the U-shaped valley. The pipeline piers 1 can be cast in situ with concrete, or they can be anchored on the ground in advance with steel piers. After the pipeline piers 1 are arranged, they are used to permanently support and fix the pipeline 7. The pipeline piers 1 extending out of the ground can raise the pipeline 7 to a certain extent, which is convenient for welding after the pipeline 7 is placed in place. At the same time, the raised pipeline 7 can facilitate the passage of water flow and debris. Compared with the method of digging a trench to semi-bury the pipeline 7, it is convenient for construction workers to weld the bottom of the pipeline 7, and water accumulation can be avoided.

[0024] After the pipeline support 1 is arranged, tracks 2 are arranged on both sides of the groove above the pipeline support 1. When the pipeline support 1 is cast in concrete, steel bars or screw holes for fixing the tracks 2 can be pre-buried in advance. A support frame 21 is arranged between two adjacent pipeline support piers 1 to support and erect the track 2, thereby reducing the number of pipeline support piers 1. At the same time, after the pipeline 7 is arranged, the outer wall of the pipeline 7 is welded and fixed to the support frame 21 by steel bars, thereby realizing the support of the pipeline 7 by the support frame 21. The top of the support frame 21 is welded and fixed to the bottom of the track 2, and the bottom of the support frame 21 is anchored to the ground. Preferably, the track 2 is made of I-beams.

[0025] like Figure 1 As shown, the track 2 is arranged along the contour of the U-shaped valley and is arranged all the way to the platform of the valley, and the winch 4 is located at one end of the track 2. The pipeline 7 is placed on the conveying assembly 3 and connected to the winch 4 through a wire rope 41. The winch 4 can lower the conveying assembly 3 and then transport the pipeline 7 to the bottom of the valley.

[0026] like Figure 3-Figure 6 As shown, the transport assembly 3 includes a support assembly 5 and a lifting assembly 6 located on both sides of the support assembly 5, and the support assembly 5 and the lifting assembly 6 are connected by a traction rod 9; The support assembly 5 includes two symmetrically arranged boxes 51, and the lifting assembly 6 includes a gantry 61 and a hand winch 62. The gantry 61 spans across two sets of rails 2. The top hook 57 of the hand winch 62 is connected to the middle of the gantry 61, and the bottom hook 57 of the hand winch 62 is provided with a sling 63. The bottom of the box 51 and the gantry 61 are provided with a pulley assembly 8 that cooperates with the rail 2.

[0027] Through the above technical solution, the support assembly 5 and the lifting assembly 6 are both slidably connected to the track 2 through the pulley assembly 8 at the bottom. At the same time, the pulley assembly 8 includes a mounting frame 81 and an I-shaped wheel 82 located below the mounting frame 81. The I-shaped wheel 82 cooperates with the track 2 using an I-beam to prevent the pulley assembly 8 from derailing and overturning.

[0028] The support assembly 5 supports the pipeline 7, and the lifting assemblies 6 on both sides are used to lower the pipeline 7 into the groove of the pipeline pier 1 after the pipeline 7 is transported to the position. At the same time, the lifting assembly 6 is used to adjust the pipeline 7 to facilitate the alignment of the pipeline 7 and then welding.

[0029] Since the support assembly 5 includes two symmetrically arranged boxes 51, a rotating shaft 52 is provided in one box 51, and a fixed shaft 53 is provided in the other box 51, and a plurality of groups of wire drums 54 are provided on the rotating shaft 52, and a steel cable 55 is provided in each group of wire drums 54, and the steel cable 55 passes through the box 51 and is connected to the fixed shaft 53, and a hand winch 56 is provided at one end of the rotating shaft 52. The rotating shaft 52 is located in the box 51 and is rotatably connected to the box 51, and the hand winch 56 is fixed to the outside of the box 51, and one end of the rotating shaft 52 passes through the box 51 and is connected to the hand winch 56, so by rotating the hand winch 56, the rotating shaft 52 can be driven to rotate, and then the wire drum 54 rotates with the rotating shaft 52, and then the steel cable 55 is retracted or lowered.

[0030] Specifically, on the valley platform, the support assembly 5 is first placed on the track 2 through the pulley assembly 8 below, and then the hand winch 56 is turned to receive the steel cable 55 into the wire drum 54 until the steel cable 55 is straightened and in a horizontal state. Since there is a locking structure in the hand winch 56, the shaft 52 will not rotate after the hand winch 56 does not move. At this time, the steel cable 55 is always kept taut and parallel to the top surface of the track 2. At this time, the pipe 7 waiting for pipe laying on the valley platform is dropped onto the steel cable 55 by a lifting device such as a crane, and the pipe 7 is supported by multiple steel cables 55. At the same time, since the top of the support assembly 5 is an open structure, it is very convenient to lift the pipe 7.

[0031] When the pipe 7 falls onto the steel cable 55, the pipe 7 is further fixed by setting a hook 57 and a strap 58 on the outside of the box 51. The strap 58 passes over the pipe 7 and is connected to the hooks 57 on both sides and tightened to prevent the pipe 7 from shaking.

[0032] After the pipe 7 is fixed on the supporting assembly 5, two lifting assemblies 6 are placed on both sides of the pipe 7 respectively. The lifting assembly 6 includes a door frame 61 and a hand winch 62. The top hook 57 of the hand winch 62 is connected to the middle part of the door frame 61, and the bottom hook 57 of the hand winch 62 is provided with a lifting device 63. The gantry 61 spans across two sets of tracks 2 and is slidably connected to the tracks 2 through the pulley assembly 8 at the bottom. The pulley assembly 8 facilitates the lifting assembly 6 to be moved to a suitable position. After the lifting assembly 6 is arranged, the lifting assembly 6 and the support assembly 5 are connected through a traction rod 9. A hinge point is provided in the middle of the traction rod 9. The two ends of the traction rod 9 are respectively connected to two adjacent pulley assemblies 8 along the direction of the tracks 2. The lifting assembly 6 and the support assembly 5 are connected through the traction rod 9. When the winch 4 drives the lifting assembly 6 on one side to move, it can also drive the adjacent support assembly 5 to move together. At the same time, the hinge point in the middle of the traction rod 9 can rotate to a certain extent to avoid the lifting assembly 6 and the support assembly 5 being connected as a rigid body, thereby affecting the movement on the U-shaped track 2.

[0033] When the lifting assembly 6 is in place, adjust the hand winch 62 to clamp the sling 63 on the two ends of the pipe 7. The sling 63 is a U-shaped structure, and the U-shaped groove of the sling 63 is clamped on the side wall of the pipe 7. At this time, the chain of the hand winch 62 connecting the sling 63 does not have an upward force on the pipe 7, but only ensures that the sling 63 is stuck on the pipe 7 and will not fall off. At this time, the pipe 7 still falls on the support assembly 5 and is supported by the steel cable 55.

[0034] When the pipeline 7 starts to be transported, the winch 4 is connected to the nearest lifting assembly 6 through the wire rope 41. After the transport assembly 3 is pushed down from the platform, the wire rope 41 of the winch 4 is slowly released to avoid losing control due to excessive speed. Figure 3 As shown, at this time, the transport component 3 and the pipeline 7 are in an inclined state, the pipeline 7 is tied tightly by the strap 58, and the friction between the pipeline 7 and the steel cable 55 also prevents the pipeline 7 from sliding down. At the same time, the lowest end of the pipeline 7 is connected to the hand winch 62 through the hanger 63, which can also prevent the pipeline 7 from sliding off the steel cable 55.

[0035] When the pipeline 7 is moved into position, the hoist 4 is braked and the conveying assembly 3 no longer moves. Figure 7 As shown, the lifting device 63 and the pipeline 7 are tightened by the hand winch 62, and the pipeline 7 is lifted by the hand winch 62. At the same time, the hand winches 62 at both ends can be adjusted respectively according to the inclination of the ground.

[0036] At this time, the binding belt 58 is removed, and the steel cable 55 is loosened by the hand winch 56 until the steel cable 55 falls to the ground under the action of gravity. At this time, the steel cable 55 can be removed from the end connected to the fixed shaft 53, and the pipeline 7 can be lowered by the hand winch 62. At this time, the pipeline 7 will not be interfered by the steel cable 55, and the pipeline 7 falls completely on the pipeline support pier 1. At the same time, the angle of the pipeline 7 can be adjusted by adjusting the hand winch 62, which is convenient for welding after the pipeline 7 is aligned, reducing manpower adjustment, and improving the efficiency of docking and lowering the pipeline 7.

[0037] After the pipeline 7 is placed, since one end of the steel cable 55 is untied, when the supporting assembly 5 is pulled back to the platform, the steel cable 55 will not be blocked by the pipeline pier 1, and the transport assembly 3 is lifted back to its original position by the winch 4. At this time, the steel cable 55 is fixed to the fixed shaft 53 to support the next group of pipelines 7.

[0038] Example 2 Based on Example 1, refer to Figure 8 For shorter and smaller pipes 7, when transporting and laying pipes in the horizontal direction, two sets of lifting components 6 can be used to complete the process. Specifically, both ends of the pipe 7 are lifted by hand winches 62 through lifting devices 63. When the pipe 7 is transported to the right place, the pipe 7 can be lowered by hand winches 62.

[0039] Example 3 Based on Example 1, refer to Fig. 9 The hand chain hoist 62 is provided with two hangers 63, one hanger 63 is clamped between the pipe walls of two adjacent pipes 7, and the other hanger 63 is clamped on the side wall of the uppermost pipe 7. The two hangers 63 can be used to lift and transport the two pipes 7. On the basis of embodiment 1, multiple pipes 7 can be transported at one time, which greatly improves the transportation efficiency.

[0040] Specifically, the supporting part of the pipeline 7 refers to Example 1. After the pipeline 7 is transported to the designated position, the hand winch 62 first drives the two pipelines 7 to be lowered together until the bottom pipeline 7 falls on the pipeline support pier 1, and then the hoist 63 connecting the two pipelines 7 at the bottom is removed. At this time, the top pipeline 7 is still suspended by the upper hoist 63 and the hand winch 62. At this time, the winch 4 drives the transport component 3 to go back a distance until it is located on the side of the newly arranged pipeline 7. At this time, the remaining pipelines 7 are continued to be lowered through the lifting component 6. Through this embodiment, the number of reset times of the transport component 3 can be reduced, and multiple pipelines 7 can be transported and arranged at one time, which can effectively improve the efficiency of pipe transportation and pipe laying.

It should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field.
