Description

Technical Field

[0001] The invention relates to a scientific research winch for hoisting, placing and recovering deep-sea equipment, in particular to a quick-detachable foot of the scientific research winch. Background Art

[0002] Scientific research winches are used for the hoisting and recovery of deep-sea equipment. They are important equipment in deep-sea exploration, salvage, and equipment collection and deployment. The foot of the scientific research winch is the main force-bearing part of the connection between the winch and the hull. The foot transfers the load at the rope end to the hull, which is related to the safety of the winch during operation. The same set of scientific research winches needs to be carried on different scientific research ships under different needs. The deck layout of the scientific research ship is different, the position on the deck surface reserved for the installation of the scientific research winch is different, and the installation requirements of the deck surface are also different. In response to the above needs, a quick-disassembly and assembly foot is developed to meet various deck installation requirements. Under the premise of ensuring sufficient structural strength, it can meet the needs of rapid placement and installation.

[0003] Conventional foot bolt installation has high requirements on the deck installation surface and is not conducive to rapid disassembly and assembly. Summary of the invention

[0004] The present invention proposes a quick-detachable foot for a scientific research winch, which is mainly used to connect the scientific research winch with a deck. Under the premise of ensuring structural strength, it can achieve quick positioning and installation functions, ensure the stable installation of the scientific research winch, and is suitable for deck surfaces of different flatness.

[0005] To achieve the above-mentioned purpose, the technical solution of the present invention is: a quick-disassembly and assembly base for a scientific expedition winch, including a frame welding base, a deck welding mounting plate, mounting pins, fastening screws, and pads. The frame welding base is welded to the scientific expedition winch structure frame, and the deck welding mounting plate is connected to the frame welding base through the mounting pins. The fastening screws connect the deck welding mounting plate and the mounting pins to the scientific expedition winch structure frame as a whole.

[0006] Furthermore, a pad is placed between the frame welding base and the deck surface required for the installation of the scientific research winch, and the deck welding mounting plate is welded to the deck to complete the quick disassembly and assembly foot installation.

[0007] Furthermore, the scientific research winch is provided with a plurality of scientific research winch quick-disassembly and assembly feet, which are welded to the deck surface after being put into position, and can effectively reduce the flatness requirements for the deck installation surface.

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

[0009] Furthermore, each scientific research winch's quick-detachable base is provided with two mounting pins, which can withstand bending moments perpendicular to the mounting surface; the bases are used in groups, and the opposite bases are grouped to withstand bending moments along the mounting surface, so that the bases used in groups can effectively constrain the forces and bending moments of the six degrees of freedom of the winch frame.

[0010] Furthermore, a transition fit with a small interference is adopted between the mounting pin and the frame welding base and the deck welding mounting plate, which can not only ensure the installation accuracy between the frame and the base and make the force transmission more uniform, but also facilitate the disassembly and installation of the mounting pin and ensure the interchangeability of the mounting pin.

[0011] Beneficial effects brought by the technical solution of the present invention

[0012] 1. The flatness requirement for the deck installation surface is reduced, and the flatness of the installation surface can be within 5mm;

[0013] 2. When the scientific research winch is installed, a single foot only needs to weld a weld between the deck welding installation plate and the deck surface, which greatly reduces the welding workload compared to the traditional hull base welding method;

[0014] 3. When disassembling the scientific research winch, remove the screws to separate the winch from the deck, remake the 2-deck welding installation plate, and repeat the installation steps to complete the installation on other hull decks;

[0015] 4. The quick-detachable foot can change the layout and quantity according to the direction and size of the winch force, and the position of the foot can also be adjusted according to the layout of the deck. BRIEF DESCRIPTION OF THE DRAWINGS

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

[0020] like Figure 1 As shown in Figure 2, a quick-disassembly and assembly base for a scientific research winch of the present invention includes a frame welding base 1, a deck welding 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 structure frame, the deck welding mounting plate 2 is connected to the frame welding base 1 through the mounting pin 3, the fastening screws 4 connect the deck welding mounting plate 2 and the mounting pin 3 with the scientific research winch structure frame as a whole, the scientific research winch is placed on the deck surface where it needs 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, and the quick disassembly and assembly base installation is completed.

[0022] Key technical points of the present invention:

[0023] 1. The quick-disassembly installation feet need to be used in groups. The scientific research winch is usually equipped with more than 6 quick-disassembly installation feet along the force direction of the frame according to calculations to ensure that each foot is balanced in force;

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

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

[0026] 4. A transition fit with a small probability of producing a small interference is uniformly selected between the mounting pin 3 and the frame welding base 1 and the deck welding mounting plate 2, which not only ensures the installation accuracy between the frame and the base and makes 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.
