Description

Technical Field

[0001] This invention relates to a scientific research winch for the hoisting and recovery of deep-sea equipment, and more particularly to a quick-release and detachable base for the scientific research winch. Background Technology

[0002] Research winches are used for the hoisting and retrieval of deep-sea equipment and are crucial equipment in deep-sea exploration, surveying, salvage, and equipment deployment and retrieval. The winch base is the main load-bearing part connecting the winch to the hull, transferring the load from the rope end to the hull and affecting the winch's safety during operations. The same research winch needs to be mounted on different research vessels for different requirements. The deck layout of the research vessel varies, the space available for winch installation on the deck differs, and the installation requirements on the deck also differ. To address these needs, a quick-assembly and disassembly base has been developed to adapt to various deck installation requirements, enabling rapid placement and installation while ensuring sufficient structural strength.

[0003] Conventional anchor bolt installation methods have high requirements for the deck mounting surface and are not conducive to quick assembly and disassembly. Summary of the Invention

[0004] The present invention proposes a quick-release and detachable base for scientific research winches, which is mainly used for connecting scientific research winches to decks. Under the premise of ensuring structural strength, it realizes the function of quick placement and installation, ensures the stable installation of scientific research winches, and is applicable to deck surfaces with different flatness.

[0005] To achieve the above objectives, the technical solution of the present invention is: a quick-release and detachable base for a scientific research winch, comprising a frame welding base, a deck welding mounting plate, mounting pins, fastening screws, and pads. The frame welding base is welded to the structural frame of the scientific research winch. The deck welding mounting plate is connected to the frame welding base through mounting pins. The fastening screws connect the deck welding mounting plate and the mounting pins to the structural frame of the scientific research winch as a whole.

[0006] Furthermore, padding blocks are placed between the frame welding base and the deck surface required for the scientific research winch to be installed, and the deck welding installation plate is welded to the deck to complete the quick-release and disassembly base installation.

[0007] Furthermore, the research winch is equipped with multiple quick-release feet, which are then welded to the deck surface after being placed in place, effectively reducing the flatness requirements of the deck installation surface.

[0008] Furthermore, the weld between the deck welding plate and the hull deck surface can withstand forces in three directions: positive, lateral, and vertical.

[0009] Furthermore, each research winch has a quick-release base with two mounting pins that can withstand bending moments perpendicular to the mounting surface; the bases are used in groups, and the opposite bases can withstand bending moments along the mounting surface, so that the use of the bases in groups can effectively constrain the forces and bending moments of the six degrees of freedom of the winch frame.

[0010] Furthermore, a small interference fit is used between the mounting pin and the frame welding base and the deck welding mounting plate. This not only ensures the installation accuracy between the frame and the base, making the force transmission more uniform, but also facilitates the disassembly and installation of the mounting pin and ensures the interchangeability of the mounting pin.

[0011] The beneficial effects of the technical solution of the present invention

[0012] 1. The flatness requirement for the deck mounting surface is reduced; the flatness of the mounting surface only needs to be within 5mm.

[0013] 2. When the scientific research winch is installed and positioned, only one weld is needed between the deck welding plate and the deck surface for each base, which greatly reduces the amount of welding work compared to the traditional hull base welding method.

[0014] 3. When disassembling the scientific research winch, simply remove the screws to separate the entire winch from the deck. Then, remake the 2-deck welding installation plate and repeat the installation steps to complete the installation of other ship decks.

[0015] 4. The quick-release feet can be arranged in different positions and quantities according to the direction and magnitude of the force on the winch, and the position of the feet can also be adjusted according to the deck layout. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1 As shown in Figure 2, a quick-assembly and disassembly base for a scientific research winch according to the present invention includes a frame welded base 1, a deck welded mounting plate 2, a mounting pin 3, a fastening screw 4, and a pad 5.

[0021] The frame welding base 1 is welded to the scientific research winch structural frame. The deck welding mounting plate 2 is connected to the frame welding base 1 through the mounting pin 3. The fastening screw 4 connects the deck welding mounting plate 2 and the mounting pin 3 to the scientific research winch structural frame as a whole. The scientific research winch is placed on the deck surface to be installed. The pad 5 is placed between the frame welding base 1 and the deck surface. The deck welding mounting plate 2 is welded to the deck to complete the quick disassembly and assembly of the base.

[0022] Key technical points of this invention:

[0023] 1. Quick-release mounting feet must be used in groups. The entire scientific research winch is usually configured with more than 6 quick-release mounting feet along the force direction of the frame according to calculations to ensure that the force on each foot is balanced.

[0024] 2. The scientific research winch is equipped with multiple feet and is welded to the deck surface after being placed in place. This can effectively reduce the flatness requirements of the deck installation surface. The flatness of a single installation surface only needs to be within 5mm.

[0025] 3. The weld between the quick-assembly and disassembly base deck welding plate 2 and the hull deck surface can withstand forces in three directions: positive (Y-axis), lateral (X-axis), and vertical (Z-axis). Each base has two mounting pins, which can withstand bending moments (X-axis and Y-axis) perpendicular to the mounting surface. The bases are used in groups, and the opposite side bases in groups can withstand bending moments (Z-axis) along the mounting surface. Therefore, the use of bases in groups can effectively constrain the forces and bending moments of the winch frame in six degrees of freedom.

[0026] 4. The mounting pin 3 is uniformly selected with a small probability of producing a small interference fit between the frame welding base 1 and the deck welding mounting plate 2. This not only ensures the installation accuracy between the frame and the base, making the force transmission more uniform, but also facilitates the disassembly and installation of the mounting pin 3, and ensures the interchangeability of the mounting pin 3.
