Description

Technical Field

[0001] This utility model relates to an oilfield equipment, more specifically, a pipe-laying and releasing device. Background Technology

[0002] In the past two years, with the large-scale development of crude oil in northern Jiangsu, the amount of pipelines used has been increasing. In 2024 alone, the Oil Construction Engineering Service Department laid and received nearly 10,000 pipelines.

[0003] Pipe banks are a common paving material used in oil and gas fields. They consist of multiple welded oil pipes, forming a planar structure approximately 4.5-4.8 meters long, 1.6-2.1 meters wide, and weighing about 1.2-1.5 tons. They can withstand the weight of drilling equipment, vehicles, and materials, preventing soil subsidence and collapse. A standard drilling or fracturing site typically requires about 150 pipe banks laid side-by-side. Compared to ground hardening, this method is unaffected by weather, has lower costs, can be reused, and protects the original ground surface at the drilling or fracturing site, allowing for rapid restoration of farmland after construction.

[0004] Current pipe-laying operations require the combined use of excavators and cranes. The cranes lift bundles of 4-5 pipe sections from the trucks, and then the excavators lay the pipe sections one by one into a tightly connected plane. A shift of 6 people is needed, including rigging, monitoring, and command. They are responsible for moving ladders, climbing trucks, securing guide ropes, and attaching slings, involving both working at heights and lifting. Sometimes, drilling and fracturing equipment need to be brought in urgently, requiring early mornings and late nights, but efficiency is difficult to improve, with only about 80 sections laid per day. Relying heavily on contractor personnel makes direct operation management very difficult, leading to more violations and higher construction costs. Utility Model Content

[0005] Therefore, it is necessary to provide a pipe-laying and releasing device to address the aforementioned technical problems.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] The shovel claw comprises several parallel arc-shaped shovel bars, each with a wedge-shaped shovel head at its end. A protruding limiting boss is provided on the lower inner side of each shovel bar, and a limiting screw hole is provided on the limiting boss. A limiting bolt is provided in the limiting screw hole.

[0009] In a preferred embodiment of this utility model, the limiting boss is welded to the shovel bar.

[0010] In a preferred embodiment of the present invention, the outer side of the shovel bar is provided with a protruding leveling protrusion, the leveling protrusion is provided with a leveling screw hole, and the leveling screw hole is provided with a leveling head.

The claws 3 are connected to the rotating seat 2 via a hydraulic cylinder 4.

[0029] The shovel claw 3 includes several parallel arc-shaped shovel bars 31. The end of each shovel bar 31 is provided with a wedge-shaped shovel head 30. The lower inner side of each shovel bar 31 is provided with a protruding limiting boss 32. The limiting boss 32 is provided with a limiting screw hole 33, and a limiting bolt 34 is provided in the limiting screw hole 33.

[0030] It should be noted that the limiting boss 32 is welded to the shovel bar 31.

[0032] like Figure 4 and Figure 5As shown, the base 1 is connected to the excavator. When it is necessary to move the pipe bank 5, the shovel claw 3 is used to grab the pipe bank 5 until it stops against the limit bolt 34. Then, the pipe bank 5 can be transported to the required position.

[0033] This pipe-laying device features a quick-connect interface design, allowing for a mere few minutes to switch from the excavator bucket to the gripper. The excavator's flexible operation and the efficiency of pipe-laying operations are nearly doubled compared to hoisting methods, significantly improving construction efficiency. Because it employs a hoist-free laying scheme, no hoisting or high-altitude work is required, greatly enhancing safety and reducing the probability of accidents. Furthermore, compared to traditional hoisting operations, this pipe-laying device significantly reduces manpower and saves production costs.

[0034] This pipe laying and unloading device is suitable for pipe laying operations in drilling sites, fracturing sites, and crossing sites (such as pre-drilling construction, fracturing construction, crossing construction, bridge reinforcement, muddy roads, etc.) and environmentally sensitive areas (such as nature reserves, farmland, etc.).

[0035] This pipe laying and retrieval device uses an excavator equipped with a "grip" to enable pipe laying and retrieval operations, reducing reliance on hoisting operations.

[0036] like Figures 5 to 9 The image shows another embodiment of this utility model. In this case,

[0037] The outer side of the shovel bar 31 is provided with a protruding leveling bump 35, the leveling bump 35 is provided with a leveling screw hole 36, and the leveling screw hole 36 is provided with a leveling head 6. The leveling bump 35 is welded to the shovel bar 31.

[0038] The leveling head 6 includes a pair of leveling screws 61. The end of the leveling screw 61 is provided with a block-shaped leveling block 62. The leveling block 62 is provided with a leveling slope 63. The leveling screw 61 passes through the leveling screw hole 36 and is connected to the fixing nut 7.

[0039] It should be noted that the leveling slope 63 is set facing the ground.

[0040] During the transfer of pipes 5, the user can use the leveling slope 63 of the leveling head 6 to level the ground, making the machine multi-functional and further improving production efficiency.
