Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, and more specifically, to a detachable support for yacht hoisting and transfer. Background Technology

[0002] When small boats or yachts under 500t are repaired, modified, or require painting or major overhaul, they are generally hoisted or towed to shore, dry dock, or floating dock using a special sled. Sometimes, they need to be transferred to the shipyard for painting or interior finishing. For small boats, sleds are generally used for direct jacking, while large yachts or ships are handled using special sleds, floating docks, or dry docks. This requires high-level shipyard facilities and involves complex processes. Furthermore, traditional boat supports cannot be disassembled, and painting operations generally require a second sled placement, where a second sled placement plan is used to offset the original sled placement position, allowing painting to be carried out on areas where the original sled placement was not feasible.

[0003] Clearly, traditional processes are cumbersome and require specialized equipment and facilities in shipyards with high hardware requirements. For boats with a displacement of less than 500t, this is a waste of resources, has a long operation cycle, and is costly. Utility Model Content

[0004] To address the aforementioned technical problems, a detachable support yacht hoisting and transfer bracket is provided. This utility model is a hoisting device for moving vessels ashore or into a dry dock. Without the need for dedicated trolleys, floating docks, or dry docks, it allows boats to be unloaded from any location with sufficient water depth and hoisting capacity. The vessels can then be transported to a factory using a transport vehicle. The bottom of the bracket can be painted, and the vessel can be launched after the operation is complete. This solves the problems of cumbersome traditional processes, underutilization of materials, resource waste, long operation cycles, and high costs.

[0005] The technical means adopted in this utility model are as follows:

[0006] A detachable support for yacht hoisting and transport includes: a bottom support, crossbeams, lifting brackets, several connecting supports, flanges, channel steel brackets, anti-corrosion treated hardwood, rubber sheets, and sandbags. Multiple horizontally arranged crossbeams are installed on the bottom support, and the multiple crossbeams are arranged longitudinally at intervals. Lifting brackets are installed at both ends of the crossbeams. Multiple rows of connecting supports are arranged longitudinally on the left and right sides of the crossbeams, and multiple connecting supports in each row are arranged horizontally at intervals. Channel steel brackets are installed on the top of each row of multiple connecting supports.

[0007] The connecting support consists of a lower first support and an upper second support, which are detachably connected. The lower end of the first support is fixedly connected to the crossbeam. The channel steel bracket is installed on the upper end of the second support of each row of multiple connecting supports. The anti-corrosion treated hardwood is fixed on the channel steel bracket. The rubber plate is installed above the anti-corrosion treated hardwood. The sandbag is placed on the rubber plate.

[0008] Furthermore, both the upper end of the first support column and the lower end of the second support column are provided with flanges, and the two flanges are connected by multiple sets of fasteners.

[0009] Furthermore, the bottom support includes two longitudinally spaced gantry frames, which are welded from steel plates, with both ends of each crossbeam welded to the gantry frames on both sides.

[0010] Furthermore, the lateral spacing between the two masts is greater than the width of the transport vehicle.

[0011] Furthermore, the crossbeam is welded from steel plates, and the lifting bracket is welded to the crossbeam.

[0012] Furthermore, the connecting support is welded to the crossbeam and the channel steel bracket.

[0013] Furthermore, the anti-corrosion treated hardwood is machined with countersunk holes, and stainless steel bolts are fitted into the countersunk holes to fix the anti-corrosion treated hardwood into the groove of the channel steel bracket.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. The bracket of this utility model allows ships to be launched without relying on special facilities such as floating docks. It can be used with gantry cranes and truck cranes, and does not require special launching facilities, making it widely applicable.

[0016] 2. The bracket of this utility model is based on the gantry structure widely used in shipyards. It has a short modification time. The detachable blocks with flange connection are placed on the bracket to prevent collisions and scratches with the hull. Even if there is a slight deviation in the line, the self-adaptive effect of bagged sand can buffer and prevent damage to the hull. It also realizes the functions of transportation and painting. The process is simple, the operation cycle is short, and the cost is low.

[0017] 3. The lifting bracket of this utility model can be used on multiple types of boats and can be quickly switched by replacing the detachable part above the flange. When the boat is small, bolt connection can be used instead of welding to achieve modular combination and switching, which has good adaptability.

[0018] Based on the above reasons, this utility model can be widely promoted in the fields of yacht repair, modification or painting. Attached Figure Description

The hull is arranged at intervals, with a channel steel bracket 6 installed on top of each row of multiple connecting pillars 4. Each connecting pillar 4 consists of a lower first pillar and an upper second pillar, detachably connected. The lower end of the first pillar is fixedly connected to a crossbeam 2. The channel steel bracket 6 is installed on the upper end of the second pillar of each row of multiple connecting pillars 4. The channel steel bracket 6 is basically parallel to the outer plate line of the rib. Anti-corrosion treated hardwood 7 is embedded and fixed on the channel steel bracket 6. The anti-corrosion treated hardwood 7 has a line that is basically consistent with the contact surface of the hull, and countersunk holes are drilled during processing for bolt fixing. A rubber plate 8 is installed above the anti-corrosion treated hardwood 7, and sandbags 9 are placed on the rubber plate 8. The rubber plate 8 and sandbags 9 are used to further match the lines, increase the contact area under stress, and protect the hull. The anti-corrosion treated hardwood 7, rubber plate 8, and sandbags 9 are fixed on the channel steel bracket 6 to contact and support the hull. The hull can be painted by removing the channel steel brackets one by one. The bracket of this invention is not only simple in structure, but also easy to operate.

[0028] Preferably, both the upper end of the first support column and the lower end of the second support column are provided with flanges 5. The two flanges 5 are connected by multiple sets of fasteners 10. The fasteners 10 are used to connect the upper and lower parts of the connecting support column 4 through the flanges 5. The flanges 5 are welded to the connecting support column 4 in pairs. The flanges 5 can be disassembled in sequence to allow the bracket to be removed from the hull for painting.

[0029] Preferably, the bottom support includes two longitudinally spaced masts 1, each welded from steel plates, used to bear the longitudinal load of the boat, one on each side (divided into two rows). The masts 1 on both sides are welded to the lower ends of each crossbeam 2. The lateral spacing between the masts 1 on both sides is greater than the width of the transport vehicle and has a safety margin. Positioning markers are respectively installed on the bow and stern sides of the masts 1.

[0030] Preferably, the crossbeam 2 is welded from steel plates and is used to bear the longitudinal load of the boat; there are several of them. Lifting brackets 3 are welded to the crossbeam 2 for lifting; the crane is connected to multiple lifting brackets 3 on both sides of the lifting bracket via lifting equipment, struts, and lifting supports. Connecting support columns 4 are welded to the crossbeam 2 at the bottom and to the channel steel bracket 6 at the top to maintain an appropriate height, which is related to the hull hull shape.

[0031] Preferably, the preservative-treated hardwood 7 is fixed to the groove of the channel steel bracket 6 via countersunk holes and stainless steel bolts. The preservative-treated hardwood 7 is used to match the hull lines and transfer the hull weight to the connecting support 4 below. The rubber sheet 8 is used to cushion the hull against the preservative-treated hardwood 7 and prevent damage to the hull and its paint. The sandbag 9 is used in direct contact with the hull to further conform to the hull lines and prevent damage to the hull and its paint.

[0032] This utility model achieves the launching and unloading of the hull by using a hoisting device, which integrates a hoisting bracket and a detachable connecting support column. After the hoisting operation is completed, the hull can be transferred by a modular transport vehicle, and the connecting support columns can be disassembled one by one to achieve the painting of the hull. The multi-functionality increases economic benefits.

[0033] The working method of this utility model:

[0034] A method for davit lifting and transfer of yachts using a detachable support (hereinafter referred to as lifting support) is provided. This method has a simple process, short operation cycle, and lower operating costs compared to floating dock operations or conventional dock entry / exit operations. The method includes the following steps:

[0035] Sl. Connect the crane to the lifting bracket 3 via lifting steel cables, support rods, and lifting brackets to ensure a safe distance of at least 1000mm between the steel cables and the hull;

[0036] S2. Use a crane to move the lifting bracket to a predetermined depth below the water surface;

[0037] S3. Tow the vessel to one end of the lifting bracket and secure it with cables;

[0038] S4. Move the lifting bracket directly beneath the vessel;

[0039] S5. Precisely adjust the ship's position;

[0040] S6. The hoisting crane raises the lifting bracket to contact the bottom of the ship, and the bottom of the ship sits on the pier (preservative-treated hardwood, grade 7).

[0041] S7. Use a hoisting crane until the ship is out of the water, and then further raise it to at least 1 meter above the dock before moving it to the shore.

[0042] Furthermore, in S2, the predetermined depth is at least 500mm below the lowest point of the vessel when the lifting bracket is lower than the lowest point of the vessel.

[0043] Furthermore, S3 specifically includes: orienting the bow of the ship toward the lifting bracket and securing it with cables so that the centerline of the ship's length direction is parallel to the longitudinal centerline of the lifting bracket, and the ship's width is within the range of the lifting bracket;

[0044] S4 specifically includes: slowly moving the lifting bracket from the bow to below the ship; when the lifting cable comes into contact with the mooring line, quickly untie the mooring line; and when the lifting cable passes the mooring line, quickly re-secure the mooring line.

[0045] S5 specifically includes: adjusting the position of the vessel so that the positioning marker on the lifting bracket is aligned longitudinally with the corresponding rib number of the vessel, and simultaneously aligned laterally with the centerline of the hull and the centerline of the lifting bracket on the same vertical plane.

[0046] Furthermore, when painting is required, the module vehicle or transport vehicle is driven into the lifting bracket, and the connecting support column 4 of the bracket is lifted off the ground by at least 300mm by hydraulic jacking.

[0047] After properly securing the cables and lifting brackets on the boat, add keel blocks and transport the entire vessel to the workshop. Then, using a hydraulic mechanism, lower the lifting brackets to the ground.

[0048] The detachable connecting struts 4 are disassembled one by one in turn, and the wooden blocks are temporarily removed from the hull for painting.

[0049] Furthermore, the above steps can be performed by adding a keel block below the rib, unscrewing the bolts on the mating surface of the flange 5, and pulling out the sandbag 9 towards the tail end. If the force is too great, the sandbag 9 can be untied to release some sand. At this time, according to the painting requirements, the connecting column 4, the channel steel bracket 6, and the wooden block can be disassembled.

[0050] After the painting is completed, the disassembled channel steel bracket 6 and the wooden blocks are put back in place, and the sandbags 9 are put back in place.

[0051] The actual lifting, transportation, and painting of the vessel verified its rationality and practicality.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
