Description

Technical Field

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

[0002] Scientific research winches are used for the lifting and recovery of deep-sea equipment and are important equipment in deep-sea exploration, exploration, salvage, and equipment deployment and retrieval. The scientific research winch foot 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 vessels to meet different needs. The deck layout of scientific research vessels is different, and the location on the deck surface reserved for scientific research winch installation is different, and the installation requirements on the deck surface are also different. In response to the above needs, a quick-disassembly and assembly foot has been developed to adapt to various deck installation requirements. While ensuring sufficient structural strength, it can be quickly positioned and installed.

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

[0004] The utility model proposes a quick-disassembly and assembly base for a scientific expedition winch, which is mainly used to connect the scientific expedition winch with the deck. Under the premise of ensuring structural strength, it can realize the functions of quick placement and installation, ensure the stable installation of the scientific expedition winch, and is suitable for deck surfaces with different flatness.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is: a quick-disassembly and assembly base for a scientific expedition winch, including a frame welding base, a deck welding mounting plate, a mounting pin, a fastening screw, and a pad. 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 pin. The fastening screws connect the deck welding mounting plate and the mounting pin to the scientific expedition winch structure frame as one.

[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 expedition winch is equipped with multiple scientific expedition winch quick-disassembly and assembly base feet, which are welded to the deck surface after being put into position, which can effectively reduce the flatness requirements of 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: forward, lateral and vertical.

[0009] Furthermore, each scientific expedition 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 use of bases 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.

[0011] Beneficial effects brought about by the technical solution of the utility model

[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 installing the scientific research winch, a single foot only needs to be welded to 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 expedition winch, remove the screws to separate the winch from the deck. Remake the 2-deck welding mounting plate and repeat the installation steps to complete the installation on other hull decks.

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

[0018] In the figure: 1-frame welding base, 2-deck welding mounting plate, 3-mounting pin, 4-fastening screw, 5-spacer. DETAILED 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-disassembly and assembly base for a scientific expedition 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 deck welding mounting plate 2 and the mounting pin 3 are fastened with the screw 4 to connect the scientific research winch structure 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, and the quick disassembly and assembly foot installation is completed.

[0022] Key technical points of this utility model:

[0023] 1. Quick-detachable mounting feet must be used in groups. The scientific expedition winch is usually equipped with more than 6 quick-detachable mounting feet along the force direction of the frame according to calculations to ensure that each foot is evenly stressed.

[0024] 2. The scientific research winch is equipped with multiple feet, which are 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 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 and Y axes). The feet are used in groups, and the opposite foot groups can withstand bending moments along the mounting surface (Z axis). Therefore, using the foot groups effectively constrains 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 generating a small interference is uniformly selected between the mounting pin 3 and 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, 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.
