Description

Technical Field

[0001] This invention belongs to the field of navigation mark technology, and in particular relates to a navigation mark transfer system and method. Background Technology

[0002] As an important navigation aid, navigation marks often involve transfers from docks to barges or from repair workshops to storage areas during their manufacturing, maintenance and deployment. Navigation marks are usually cylindrical structures with floating sections and neck sections, top-heavy, irregular in shape, and large in size and weight, which poses significant challenges to their safe and efficient transfer operations.

[0003] Currently, the transfer of navigation marks mainly relies on general-purpose lifting equipment (such as gantry cranes and truck cranes). Although lifting equipment can complete the lifting, when used for long-distance horizontal transportation, problems such as slow equipment movement, limited path (must be within the effective boom of the crane), large occupation of large lifting equipment resources leading to low efficiency, and significant safety risks in high-altitude long-distance hoisting are common. This mode is usually only suitable for very short-distance relocation, and its main advantage lies in vertical hoisting.

[0004] If flatbed trucks are used for horizontal transport, there are fundamental difficulties in the loading process. First, after the vertical navigation beacon is lifted by lifting equipment, it relies entirely on multiple workers to adjust its posture in the air using traction ropes and other means before attempting to lower it onto the flatbed truck. Second, on the flatbed truck, it can only be temporarily secured by wooden blocks, wire ropes, and hand-operated hoists, which is extremely cumbersome and of questionable reliability. This process is time-consuming and labor-intensive, and the effectiveness of the fixation depends on the workers' experience. During transportation, it is very easy for it to loosen or shift due to vibration, posing significant safety hazards.

[0005] In summary, existing technologies lack a dedicated system and method that can seamlessly integrate the precise loading, secure fixing, efficient horizontal transportation, and rapid vertical hoisting preparation of navigation aids. Summary of the Invention

[0006] The purpose of this invention is to provide a navigation mark transfer system, which combines a horizontal conveying device and a vertical lifting device to form a complete navigation mark transfer system. The system first uses the U-shaped end support at the front end of the horizontal conveying device to drive the railcar for efficient horizontal transport. After reaching the destination, the vertical lifting device, through its adjustable lifting point design, quickly matches the center of gravity and directly performs vertical lifting, eliminating the conversion stagnation and repetitive positioning between links, thereby achieving a systematic improvement in efficiency, safety and reliability as a whole.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: The present invention is a navigation mark transfer system, including a horizontal conveying device for horizontal transfer of navigation marks and a vertical hoisting device for hoisting navigation marks; The horizontal conveying device includes a railcar and a U-shaped end support. The track vehicle has an opening at the center of its front end, and supports are provided on both sides of the opening. The end support is hinged between the two supports, and a set of arc-shaped positioning edges are provided on the inner bottom surface of the end support. The top of the railcar is fixed with three pad beams. The middle of the pad beams is provided with a concave support structure adapted to the navigation mark. The top of the pad beams at the front and rear ends of the railcar is fixed with a set of symmetrically distributed arc-shaped supports adapted to the perimeter of the navigation mark. The vertical hoisting device includes hoisting equipment and a hoisting beam; The top edge of the hoisting beam is integrally provided with an upper horizontal edge along its length, and the upper horizontal edge is provided with several hoisting ports that are connected to the hooks of the hoisting equipment. The bottom edges at both ends of the hoisting beam are integrally provided with lower horizontal edges, and the lower horizontal edges are provided with several lifting holes linearly.

[0008] Furthermore, the navigation beacon includes a float section and a neck section coaxially connected. The outer diameter of the float section is larger than the outer diameter of the neck section. The connection surface between the float section and the neck section is a transition end with an arc-shaped structure. The bottom of the float section is symmetrically provided with two lower lugs. The circumferential side of the neck section is provided with an upper lug that is linearly distributed with the lower lugs. The top of the neck section is provided with an inner hole.

[0009] Furthermore, the three support beams are respectively the first beam, the second beam, and the third beam arranged sequentially from front to back on the track vehicle. The middle section of the first beam, the second beam, and the third beam is provided with an arc-shaped opening, and an arc-shaped plate is fixed inside the arc-shaped opening. The arc-shaped opening and the arc-shaped plate are combined to form a support part.

[0010] Furthermore, the supporting portions of the first and third beams face the front of the railcar, the supporting portion of the second beam faces the rear of the railcar, and the pad beam has several reinforcing ribs linearly arranged on the side opposite to the supporting portion and the top surface of the railcar.

[0011] Furthermore, both the first beam and the third beam are provided with two symmetrical arc-shaped supports on both sides of the support portion, and the arc-shaped supports on the first beam and the third beam are respectively adapted to the peripheral side of the neck section and the peripheral side of the floating body section.

[0012] Furthermore, the railcar is equipped with pin mechanisms on both sides of its rear end, and a set of anti-collision pads is fixed on both the front and rear sides of the railcar.

[0013] Furthermore, it also includes a ground rail for the movement of the railcar, the ground rail having several working areas, and locking sleeves provided on both sides of the ground rail in the working areas, the pin mechanism being adapted to the locking sleeves.

[0014] A method for transferring a navigation mark in a transfer system includes the following steps: The SS01 railcar moves along the ground rail to the work area, where it is positioned and locked by the cooperation of the pin mechanism and the locking sleeve. SS02 uses lifting equipment to lift the two lower lifting lugs of the navigation mark. After lifting, the navigation mark is in a state where the neck end is facing down, and it is moved to the end support seat at the front of the railcar. SS02 Positions the inner hole of the buoy concentrically with the arc-shaped positioning edge of the end support. Using the hinge point of the end support and the support as the axis, the buoy is flipped from a vertical state to an inclined state. The float section of the buoy fits into the support part of the third beam, the neck section of the buoy fits into the support part of the first beam, and the transition end face of the buoy fits into the inner wall of the support part of the second beam. The two arc-shaped supports of the first beam and the third beam respectively support the peripheral side of the neck section and the peripheral side of the float section. At this time, the upper lifting lug and the lower lifting lug are both in the upper position. The SS03 drive railcar travels along the ground rail to transport navigation marks horizontally over long distances until they reach the target area; SS04 Select the corresponding lifting port on the lifting beam according to the type and specifications of the navigation mark. Install a sling on the upper and lower lifting lugs in the area above the navigation mark. Select two lifting holes on the lower horizontal side of the sling according to the center of gravity of the navigation mark, so that the center of gravity of the navigation mark and the lifting point of the lifting beam are aligned on the vertical line. Then lift vertically for transfer.

[0015] The present invention has the following beneficial effects: 1. This invention combines a horizontal conveying device and a vertical hoisting device into a complete navigation mark transfer system. The system first uses the U-shaped end support at the front end of the horizontal conveying device to safely and smoothly complete the attitude conversion and fixation from vertical hoisting to horizontal loading. Then, the driving railcar can carry out efficient horizontal transportation. After arriving at the destination, the vertical hoisting device, through its adjustable hoisting point design, quickly matches the center of gravity and directly performs vertical hoisting. This systematic integration eliminates the conversion stagnation and repetitive positioning between links, realizes the assembly line and stability of the transfer operation, and thus achieves a systematic improvement in efficiency, safety and reliability as a whole.

[0016] 2. This invention integrates the lifting and hoisting process with the horizontal loading process into the front U-shaped end support. By utilizing the automatic alignment between the arc-shaped positioning edge within the support and the inner hole of the buoy end, the operator can use a crane as power and the hinge point as the axis to safely, smoothly, and controllably flip the vertical buoy into a precise inclined transport posture in one go. This completely replaces the high-risk and low-efficiency process of relying on multiple people to manually pull and adjust the posture in the hoisting state in traditional operations, realizing the mechanization and standardization of loading actions.

[0017] 3. This invention integrates multi-point support, circumferential limiting, and system locking functions into a horizontal conveying device. The three specific-oriented pad beams and their supporting parts precisely fit the contour of the navigation beacon cylinder, achieving stable three-point support and axial limiting. The arc-shaped supports at both ends effectively prevent circumferential rolling. Combined with the weight of the navigation beacon, this invention replaces the cumbersome and unreliable manual binding that relies on wooden blocks and steel wire ropes on traditional flatbed trucks, ensuring absolute stability and safety during long-distance transportation.

[0018] 4. This invention integrates the lifting point adjustment function into a dedicated lifting beam. By selecting different lifting ports on the upper horizontal side to match the crane hook, and selecting different lifting holes on the lower horizontal side to connect the slings at both ends of the navigation mark, operators can quickly and intuitively ensure that the line of action of the lifting force passes precisely through the actual center of gravity of the navigation mark based on experience or simple trial adjustments. This ensures that the center of gravity and the lifting point are on the same vertical line, guaranteeing lifting stability and greatly improving the efficiency and safety of the vertical lifting process.

[0019] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
