Description

Technical Field

[0001] This utility model relates to a hoisting device for maritime rescue equipment, belonging to the technical field of hoisting devices. Technical Background

[0002] Currently, rescue vessel (workboat) docks are not equipped with fixed or rail-mounted shore cranes for loading and unloading. This is because the dock's foundation, except for the solid reinforced concrete foundation with bollards (approximately 6 meters x 6 meters x 4 meters), consists of rammed earth surface interlocking blocks. Installing fixed lifting equipment on the dock would require special treatment of the foundation, which is very expensive. With increasing public demand and improved national emergency response capabilities, timeliness is increasingly emphasized in emergency response. Maritime rescue has achieved 24-hour standby, and the ability to load and unload emergency rescue equipment at rescue vessel (workboat) docks has become the norm. Currently, the following two methods are used for loading and unloading emergency rescue equipment:

[0003] 1. Large rescue vessels have their own cranes for loading and unloading maritime rescue equipment, but the crane boom span is limited, restricting its use. Small and medium-sized rescue vessels and other transport vessels do not have their own cranes and need to rent or equip themselves with truck cranes for loading and unloading maritime rescue equipment. Because rescue operations are carried out 24 hours a day, the timeliness of truck cranes is limited.

[0004] 2. Using a mobile crane for loading and unloading maritime rescue equipment is expensive and requires a dedicated crane operator on duty 24 hours a day. Renting a mobile crane is often not timely and cannot guarantee efficiency.

[0005] Therefore, there is an urgent need for a maritime rescue equipment hoisting device that can solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a hoisting device fixed to the foundation of the dock bollard. This hoisting device enables the loading and unloading of maritime emergency rescue equipment at any time, ensuring high timeliness of emergency response. It can also be disassembled at any time when there is a specific task, making it flexible and convenient to use.

[0007] The present invention relates to a lifting device for marine rescue equipment, characterized in that it includes a support mechanism 14 fixed on a dock foundation 13 with bollards. The support mechanism includes multiple rows of threaded steel bars anchored to the ground. Multiple steel bars are horizontally and vertically tied between the threaded steel bars to form a steel cage 6. A steel plate 1 is provided above the steel cage 6 and is fixed to the threaded steel bars. Concrete is poured into the steel cage 6 to compact the threaded steel bars, steel plate 1, and steel cage 6 into a single unit to form the support mechanism. An electric hydraulic slewing marine crane 2 is installed on the upper surface of the steel plate 1. The steel plate 1 and the electric hydraulic slewing marine crane 2 are detachable through a connecting component 16. A boom support mechanism 3 is also anchored near the support mechanism to support the boom of the electric hydraulic slewing marine crane 2.

[0008] Preferably, the threaded steel group includes four rows of threaded steel groups, each row of threaded steel groups is composed of six threaded steel bars 4 with a diameter of 22mm, the anchoring depth of the threaded steel group is 200mm, and the steel plate 1 is welded to the top of the threaded steel group.

[0009] Preferably, the support mechanism 3 is rectangular, with a length × width × height of 2000 mm × 1100 mm × 400 mm;

[0010] Preferably, a formwork 5 is set around the reinforcing cage 6, and the formwork 5 is removed after the concrete is poured into the reinforcing cage 6.

[0011] Preferably, the steel plate 1 has a thickness of 10mm, and a rectangular opening 7 is provided in the center of the steel plate 1 to facilitate the pouring of concrete. Four rows of threaded steel bars are evenly distributed on both sides of the length direction of the rectangular opening 7.

[0012] Preferably, the bottom of the boom support mechanism 3 is anchored to the ground, and the top is provided with a fork-shaped support 8;

[0013] Preferably, the connecting component includes multiple parallel first connecting plates 9 welded to the bottom of the steel plate 1, and a second connecting plate 10 for use with the connecting plates 9 welded to the lower surface of the electro-hydraulic slewing ship crane 2. Multiple mounting holes 11 with corresponding positions are opened along the length direction of the first connecting plates 9 and the second connecting plates 10. By tightening bolts 12 in the mounting holes 11, the first connecting plates 9 and the second connecting plates 10 are fastened together, thereby realizing the detachable installation of the electro-hydraulic slewing ship crane 2 on the support mechanism.

[0014] This utility model discloses a hoisting device for maritime rescue equipment, which has an ingenious structural design and the following beneficial effects:

[0015] 1. This utility model does not require special treatment of the wharf foundation. The standard for the foundation of the rescue boat (work boat) wharf with mooring bollards is 350KN. The strength of the mooring bollard foundation is sufficient to support a crane with a load of 5 tons. The support structure is cleverly designed, with sufficient strength and easy construction, resulting in low construction cost.

[0016] 2. This utility model drills 24 holes (4 rows x 6 holes = 24 holes, each 200mm deep) in the foundation of the bollards, anchoring 24 threaded steel bars with a diameter of 22mm. Reinforcing cages are tied between the threaded steel bars, and a 10mm thick steel plate is welded to the top of each threaded steel bar. A 2000×1100×400mm support structure is formed by pouring concrete. Structural components that can be connected to an electric hydraulic slewing ship crane are welded onto the steel plate. After installation, the overall height of the crane is approximately 2.5 meters, which does not affect the daily use of the dock. The crane can be disassembled at any time for specific tasks. This utility model's crane has a 13-meter boom and a 5-ton load capacity, suitable for loading and unloading emergency rescue equipment. It solves the difficult problems mentioned in the background technology and is applicable not only to rescue-specific docks but also to all workboat docks. Attached Figure Description
