Description

Technical Field

[0001] This invention relates to the field of shipbuilding and repair technology, and specifically to an orthogonal nested conveying system and platform. Background Technology

[0002] In the shipbuilding and repair industry, mobile lifting work platforms are indispensable equipment in shipyard production and high-altitude operations. Their performance directly affects production efficiency and operational safety. Shipyard operating environments have significant unique characteristics: on the one hand, processes such as welding, grinding, sandblasting, and painting generate large amounts of dust, which easily adheres to equipment surfaces and critical components, leading to malfunctions; on the other hand, the confined space inside dry docks makes it highly susceptible to collisions between the mobile lifting work platform's conveyor system and the ship or dry dock during operation, increasing the risk of component damage. Furthermore, dry docks typically employ shift work, requiring the lifting platform to operate continuously for extended periods, placing extremely high demands on system reliability.

[0003] Existing multi-stage conveyor systems mainly have three layouts: first, a dual-stroke conveyor system with independent distribution on both sides of the boom; second, a conveyor system with the boom stacked vertically on one side; and third, a conveyor system with the boom integrated into the boom. These traditional layouts have revealed numerous problems in practical applications: Firstly, space utilization is low. Traditional conveyor systems often protrude from the sides of the boom or occupy a large amount of space inside the boom, making it difficult to arrange them reasonably in a limited dock environment and easily causing collisions between the equipment and the ship.

[0004] Secondly, transmission stability is poor. Traditional conveyor systems lack effective external protection. In dusty environments, the cable chains and internal wiring harnesses are exposed, making them prone to wear, corrosion, and jamming, resulting in unstable power and signal transmission.

[0005] Third, maintenance is difficult. For built-in conveyor systems, once a failure occurs, it is often necessary to disassemble a large number of components on the upper part of the vehicle, including the boom, counterweight, telescopic system and conveyor system, which leads to a significant increase in maintenance costs and time. Summary of the Invention

[0006] The technical problem to be solved by this invention is that current multi-stage conveying systems suffer from low space utilization, unstable power and signal transmission, easy wear and corrosion of drag chains and internal wiring harnesses, and difficulty in maintenance in special operating environments such as small shipyards and heavy dust.

[0007] To solve the aforementioned technical problem, the technical solution adopted by the present invention is as follows: In a first aspect, an orthogonal nested conveying system is provided, comprising: a boom section one, a boom section two, a boom section three, and a boom section four nested in stages; The boom two-section sleeve, boom three-section sleeve, and boom four-section sleeve move synchronously with the boom two-section, boom three-section, and boom four-section respectively; An outer conveying subsystem positioned above the boom includes a first cable chain for power and signal transmission between boom section one and boom section two; An inner conveying subsystem located inside the outer conveying subsystem includes a second cable chain for power and signal transmission between the two-section boom and the four-section boom. The first and second cable chains are arranged orthogonally. It also includes a protective cover, which is attached to one section of the boom.

[0008] Furthermore, a first fixed bracket and a second fixed bracket are respectively provided on the first boom section and the second boom sleeve. One end of the first cable chain is fixed to the first fixed bracket by bolts, and the other end is fixed to the second fixed bracket by bolts.

[0009] Furthermore, the second and fourth boom sleeves are also provided with a third and a fourth fixed bracket; one end of the second drag chain is fixed to the third fixed bracket by bolts, and the other end is fixed to the fourth fixed bracket by bolts.

[0010] Furthermore, the four-section boom, the three-section boom, and the two-section boom are respectively provided with a fifth fixed bracket, a sixth fixed bracket, and a seventh fixed bracket; the four-section boom sleeve is fixed to the fifth fixed bracket by bolts, the three-section boom sleeve is fixed to the sixth fixed bracket by bolts, and the two-section boom sleeve is fixed to the seventh fixed bracket by bolts.

[0011] Furthermore, the protective cover comprises multiple segments, each of which is bolted to one section of the boom.

[0012] Furthermore, the weight of each segment shall not exceed 20kg and the length shall not exceed 2000mm.

[0013] Furthermore, one end of the protective cover is also provided with a rubber sealing structure, which is used to seal the inside of the protective cover when the two sections of the boom are extended or retracted.

[0014] Furthermore, it also includes nylon sealing structures, which are respectively installed at the front ends of the second and third boom sleeves.

[0015] In a second aspect, an orthogonal nested conveying platform is provided, the orthogonal nested conveying platform comprising the orthogonal nested conveying system as described in the first aspect.

[0016] The beneficial effects of this invention are as follows: 1. This invention employs a multi-stage nested boom section, boom section, boom section, and boom section, and includes boom section sleeves that move synchronously with the boom section, boom section, and boom section, respectively. This allows the multi-stage boom to maintain stable synchronization during extension and retraction, improving the stability of power and signal transmission.

[0017] 2. By setting an outer conveying subsystem including a first drag chain above the boom and an inner conveying subsystem including a second drag chain inside it, and arranging the first and second drag chains orthogonally, the utilization rate of the space above the boom is effectively improved, interference between subsystems is reduced, and the reliability of power and signal transmission is ensured.

[0018] 3. By installing a protective cover at one section of the boom, the outer and inner conveying subsystems are enclosed and protected, preventing dust, foreign objects and mechanical collisions from damaging the cable chain and internal wiring harness. This significantly reduces the risk of component damage and failure, and improves the reliability and safety of the system in complex operating environments. Attached Figure Description

[0022] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0023] like Figure 1 As shown, an orthogonal nested conveying system is provided, including a series of nested boom sections 4, 3, 2, and 1, wherein the boom sections 3, 2, and 1 are capable of telescopic movement relative to the boom section 4.

[0024] Specifically, the orthogonal nested conveying system includes a boom sleeve 9, a boom sleeve 8, and a boom sleeve 7 that move synchronously with the boom section 3, boom section 2, and boom section 1, respectively. The boom sleeve 9, boom section 8, and boom section 7 are respectively fixed to fixed brackets at corresponding positions of the boom section 3, boom section 2, and boom section 1 by bolts, so that each sleeve and the corresponding boom remain synchronized during telescopic movement.

[0025] like Figure 2 As shown, the orthogonal nested conveying system includes an outer conveying subsystem positioned above the boom. This outer conveying subsystem includes a first cable chain 5 for power and signal transmission between the first boom section 4 and the second boom section 3. A first fixed bracket 501 and a second fixed bracket 502 are respectively provided on the first boom section 4 and the second boom section sleeve 9. One end of the first cable chain 5 is bolted to the first fixed bracket 501, and the other end is bolted to the second fixed bracket 502.

[0026] like Figure 1 As shown, it also includes an inner conveying subsystem located inside the outer conveying subsystem. The inner conveying subsystem includes a second cable chain 6, which is used for power and signal transmission between the two-section boom 3 and the four-section boom 1. The two-section boom sleeve 9 and the four-section boom sleeve 7 are respectively provided with a third fixed bracket 601 and a fourth fixed bracket 602. One end of the second cable chain 6 is fixed to the third fixed bracket 601 by bolts, and the other end is fixed to the fourth fixed bracket 602 by bolts.

[0027] It should be noted that the first cable chain 5 and the second cable chain 6 are arranged orthogonally to form an orthogonal nested transmission layout, which effectively improves space utilization and reduces interference between components.

[0028] like Figure 3 As shown, to ensure the reliability of the boom and sleeve fixation, the four-section boom 1, the three-section boom 2, and the two-section boom 3 are respectively equipped with a fifth fixed bracket 701, a sixth fixed bracket 801, and a seventh fixed bracket 901. The four-section boom sleeve 7 is fixed to the fifth fixed bracket 701 by bolts, the three-section boom sleeve 8 is fixed to the sixth fixed bracket 801 by bolts, and the two-section boom sleeve 9 is fixed to the seventh fixed bracket 901 by bolts, so that the multi-stage sleeves maintain stable synchronization during telescopic movement.

[0029] In one specific embodiment, a protective cover 10 is also included. The protective cover 10 is connected to a section of the boom 4 and is used to enclose and protect the outer and inner conveying subsystems to prevent dust, foreign objects and mechanical collisions from damaging the cable chain and internal wiring harness.

[0030] Specifically, the protective cover 10 includes multiple sections, each of which is fixed to one section of the boom 4 by bolts, facilitating disassembly and maintenance. In one specific embodiment, the weight of each section is no more than 20kg and the length is no more than 2000mm, making it easy to handle manually and install quickly.

[0031] like Figure 4 As shown, to improve sealing performance, in a specific embodiment, a rubber sealing structure 101 is provided at one end of the protective cover 10. This structure seals the internal space of the protective cover when the second-section boom sleeve 9 extends or retracts, ensuring that the interior remains fully enclosed at all times. The nylon sealing structure 802 is respectively located at the front ends of the second-section boom sleeve 9 and the third-section boom sleeve 8. This structure maintains an internal seal when the third-section or fourth-section boom sleeve extends or retracts, ensuring that the cable chain moves entirely within the enclosed space of the sleeve, avoiding interference from the external environment.

[0032] In one specific embodiment, an orthogonal nested conveyor platform is also provided, including the above-mentioned orthogonal nested conveyor system. The orthogonal nested conveyor system is combined and installed with the chassis, lifting arm and operating system of the mobile lifting work platform for high-altitude operations and long-term continuous operations in the process of ship manufacturing and maintenance.
