[0001] The present invention relates to the technical field of automated warehousing in maritime shipping bases, in particular to an automated pipe arrangement and stacking device for oil casings in maritime shipping logistics bases. Background Art

[0002] At present, the oil casing transshipment process at home and abroad mainly relies on manual labor. Before entering the site, it is transported to the base by sea and vehicle over long distances, and then unloaded by a mobile crane. At the same time, on-site pipe laying operations are carried out by combining manual labor with mobile cranes. This current casing operation mode requires at least one trailer, one crane, and five workers each time. The maritime logistics transportation base is the main logistics site for oil casing in my country. The maritime site has a large workload, and each pipe operation adopts a purely manual operation mode, which has low operation efficiency. Resources such as machinery and manpower are occupied for a long time, and the labor intensity is high, which is not conducive to the turnover of base resources. At the same time, the recovery rate of wire ropes, D-bolts and other tie-ins is low, which greatly increases the operation cost. Therefore, there is an urgent need for an automated pipe laying and stacking device for oil casing in the maritime logistics base. Summary of the Invention

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Reference Figure 1-7 The present invention discloses an automatic pipe arrangement and stacking device for oil casings in a maritime logistics base, comprising a feed turning mechanism 1, a horizontal conveying mechanism 2 for conveying oil casings 7, a single-pipe conveying mechanism 3 for conveying a single oil casing 7, a stacking mechanism 4 for stacking oil casings 7 in a single layer, and a transfer mechanism 5 for aligning the oil casings 7, which are arranged in sequence.

[0029] The feeding turning mechanism 1 includes no less than two groups of feeding turning wheels 103, which are rotated by the turning assembly. Each group of feeding turning wheels 103 is provided with a receiving groove for accommodating bundles of oil casing 7. The feeding turning wheel 103 includes three states. In the first state, the receiving groove of the feeding turning wheel 103 is used to carry the bundle of oil casing. In the second state, the feeding turning wheel 103 is used to transfer the oil casing 7. In the third state, the feeding turning wheel 103 transfers the loosened oil casing 7 to the horizontal conveying mechanism 2; the turning assembly includes a feeding turning bracket 101 arranged below the feeding turning wheel 103, and a feeding roller 102 which is slidingly connected to the feeding turning wheel 103 is fixed on the feeding turning bracket 101. A feeding double chain 104 is connected to the side wall of the feeding turning wheel 103, and the feeding double chain 104 is driven to rotate by the feeding motor 105. The feeding double chain 104 is driven by the feeding motor 105 to switch the feeding turning wheel 103 between three states; the feeding motor 105 is a 90° motor.

[0030] The horizontal conveying mechanism 2 is a horizontal conveyor belt arranged in a horizontal direction, and the oil casing 7 is transported by the horizontal conveyor belt.

[0031] The single-tube conveying mechanism 3 is a rubber tooth conveyor belt, on which rubber teeth 31 are fixedly provided. A slot 32 that can only receive one oil casing 7 is formed between adjacent rubber teeth 31. Since the slot 32 can only receive one oil casing 7, the oil casing 7 is separated by the single-tube conveying mechanism 3.

[0032] The stacking mechanism 4 is an inclined platform, which includes an inclined base 401 arranged at an angle. The end of the inclined base 401 close to the single-tube conveying mechanism 3 is higher than the end close to the transfer mechanism 5. The end of the inclined base 401 close to the transfer mechanism 5 is fixedly connected to a baffle 402. Under the action of gravity, only one row of oil casing 7 can be stacked on the inclined base 401.

[0033] The transfer mechanism 5 comprises symmetrically arranged transfer vehicles 505. Each set of transfer vehicles 505 is slidably connected to a lifting support frame 502. The lifting support frames 502 are connected to several sets of spiral rollers 501. The spiral rollers 501 are driven by hydraulic motors 506, which control their operation. The spiral force ensures that the ends of the oil casing 7 are aligned. Vertically arranged sliding rods are fixedly connected to the transfer vehicles 505. The lifting support frames 502 are slidably connected to the sliding rods. The lifting support frames 502 are controlled to move up and down by hydraulic cylinders. The stroke of the hydraulic cylinders is greater than the height difference between the two ends of the tilting base 401. This ensures that the lifting support frames 502 and spiral rollers 501 can lift the oil casing 7, thereby ensuring that it passes through the baffle 402.

[0034] Each set of transport vehicles 505 is fixedly provided with an infrared signal transmitting and receiving component 503. The two sets of infrared signal transmitting and receiving components 503 on the two sets of transport vehicles 505 ensure that the two sets of transport vehicles 505 are aligned in real time. A far-focus vision module 504 is fixedly provided on the transport vehicle 505. Due to the complex ground conditions of the site, the far-focus vision module 504 is used to assist in positioning. The transport vehicle 505 adopts a steering wheel structure, which can achieve free movement in multiple directions and angles. A short-range image recognition module 507 is fixedly provided on the transport vehicle 505. Several sets of limit switches 508 are fixedly provided on each set of lifting support frames 502. The limit switches 508 are set between adjacent spiral push rollers 501. The distance between adjacent spiral push rollers 501 is the same as the diameter of the oil casing 7.

[0035] The working process of this embodiment is as follows:

[0036] First, a mobile crane places the bundled oil casing 7 on the plane of the feed turning wheel 103. Powered by the feed motor 105, the feed turning wheel 103 rotates via the feed double chain 104. When the oil casing 7 rotates to 45°, the casing straps are manually removed. The feed turning wheel 103 continues to rotate to 90°, after which the oil casing 7 rolls onto the horizontal conveyor belt. After reaching 90°, the feed turning wheel 103 stops for 5 seconds and then automatically returns to the 0° position.

[0037] Secondly, after the feeding turning mechanism 1 places the oil casing 7 on the horizontal conveyor belt, the horizontal conveyor belt drives the oil casing 7 forward; when the oil casing 7 encounters the single-tube conveying mechanism 3, the oil casing 7 on the horizontal conveyor belt is brought into the card slot 32 through the rubber card teeth 31, and it is ensured that each card slot 32 can only drive one horizontal oil casing 7 to move in a single movement.

[0038] Again, the oil casing 7 rolls down from the higher side of the inclined base 401 to the other side and is stopped by the baffle 402 , so that the oil casing is concentrated at the lowest point of the inclined base 401 .

[0039] Finally, the transfer vehicles 505 on either side of the site are aligned in real time using infrared signal transmitters and receivers 503. Due to the complex ground conditions, a telescopic vision module 504 assists in positioning. The spiral push rollers 501 on both vehicles, driven by the entire transfer mechanism, insert into the lower ends of the oil casings 7 arranged on the inclined platform. When the oil casings 7 are lifted to a certain height via the lifting support frame 502, the hydraulic motors 506 rotate the spiral push rollers 501, aligning the oil casings 7. The transfer vehicles 505 then move to the cement base 6 for placement. The spiral push rollers 501 stop rotating when all the oil casings 7 contact the limit switches 508. During the lifting and placement process, the short-range image recognition module 507 takes real-time photos of the current position for close-range positioning, ensuring that the spiral push rollers 501 accurately insert and place the oil casings 7.
