Description

Technical Field

[0001] This utility model relates to the field of product transfer technology, specifically to an auxiliary tool for improving the efficiency of lifting and transferring underwater vehicles. Background Technology

[0002] When a certain type of product (an underwater vehicle) is transferred to the ship's hold, it needs to be crated first, and then transported to the ship's hold by a battery-powered vehicle for lake testing. During loading, four workers are required to lift each crate, and eight crates need to be loaded each time, which is time-consuming and labor-intensive. If a crane is used to transport the crates to the battery-powered vehicle, each lift requires raising the crate and threading the lifting rope through the bottom of the crate, and only two crates can be lifted at a time, plus the crane's movement is very slow. Although this method saves manpower, the loading efficiency is low. When the product is transferred to the dock, a ship's crane is used to lift the crates to the ship's hold. During this process, four workers are required to raise the crates and thread the lifting rope through the bottom of the crates, and only two crates can be lifted at a time, resulting in low transfer efficiency and being time-consuming and labor-intensive.

[0003] The current transshipment environment has the following problems: (1) Four workers are needed to load the boxes onto the truck, which is time-consuming and labor-intensive. If the overhead crane is used to transport the boxes to the electric vehicle, although it saves manpower, the loading efficiency is not high. (2) When the boxes are hoisted to the ship's hold, the hoisting efficiency is not high, and each time the boxes are hoisted, workers are needed to lift them up and thread the hoisting ropes from the bottom, which is time-consuming and labor-intensive. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides an auxiliary tool for improving the efficiency of lifting and transporting underwater vehicles. This tool serves as a carrier for underwater vehicles, eliminating the need to pack them into boxes before transporting them. Furthermore, the underwater vehicles are erected, effectively reducing the difficulty of threading lifting ropes and improving work efficiency. In addition, the lifting brackets in the tool can be assembled and used according to actual conditions, thereby enabling the simultaneous transport of multiple underwater vehicles and further improving the efficiency of underwater vehicle transport.

[0005] Specifically, this utility model provides an auxiliary tool for improving the efficiency of lifting and transporting underwater vehicles, including: a lifting support, wherein the lifting support includes:

[0006] A mounting rack for placing underwater vehicles;

[0007] A support assembly, connected to the placement rack, is used to support the placement rack so as to elevate the placement rack;

[0008] Fastening components, mounted on the mounting frame, are used to secure the underwater vehicle.

[0009] There is at least one hoisting bracket. When the number of hoisting brackets is greater than one, two adjacent hoisting brackets can be detachably connected.

[0010] Furthermore, the support assembly includes: multiple sets of support frames, each set of support frames including two lower legs, the two lower legs being symmetrically arranged on both sides of the placement frame for supporting the placement frame.

[0011] Furthermore, each set of support frames also includes: two upper legs, which are arranged symmetrically with the two lower legs respectively.

[0012] Furthermore, when the number of the hoisting brackets is greater than one, the support frames of two adjacent hoisting brackets are detachably connected by bolts.

[0013] Furthermore, the fastening assembly includes:

[0014] The lower clamp is used to secure the device to the mounting frame.

[0015] The upper clamp and the lower clamp are detachably connected, and the two together encircle and hold the underwater vehicle.

[0016] Furthermore, both the lower clamp and the upper clamp have a protective layer on their inner walls.

[0017] Furthermore, there are two placement racks, which are arranged symmetrically at the center.

[0018] Working principle:

[0019] When transferring the hull, two are placed on the placement frame, one facing up and the other facing down. The hull is then secured to the placement frame using upper and lower clamps and bolts. Finally, the entire auxiliary equipment is tied with a hoisting rope and the hull is hoisted onto the ship.

[0020] When multiple sets of vehicles need to be transferred, two or more lifting brackets are connected by bolts. The connection methods include side-by-side and stacking. After connection, the vehicles are placed on the placement frame and secured with clamps to form a whole. Then, the auxiliary equipment and vehicles are lifted onto the ship.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] (1) The auxiliary tool provided by this utility model eliminates the need for packing and hoisting when transporting the aircraft, and the entire placement frame is supported by the support components so that the hoisting rope can be threaded through, thereby effectively improving work efficiency and reducing labor costs.

[0023] (2) The hoisting bracket can be assembled in multiple ways, which can realize the simultaneous hoisting of multiple vehicles and improve the efficiency of product transfer. Attached Figure Description

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0035] Example 1

[0036] This embodiment provides an auxiliary tool to improve the efficiency of lifting and transporting underwater vehicles, including at least one lifting bracket. Multiple lifting brackets can be assembled and used with bolts as needed. Specifically, as shown... Figure 1-2As shown, each lifting bracket includes: a placement frame 1, a support assembly, and a fastening assembly. Two placement frames 1 are provided, each made of 50mm x 50mm angle aluminum L-shaped profile, with a frame size of 1516mm x 174mm. The two placement frames 1 are centrally symmetrically assembled. During transport, the two underwater vehicles 4 are also placed centrally symmetrically to balance the center of gravity and improve stability. The longest sides of the two placement frames 1 are welded together by a connecting plate made of 1516mm x 55mm x 4mm aluminum plate. 6mm diameter holes are drilled on both sides of the long side of the placement frame 1 for mounting four U-shaped galvanized bolts 11. These U-shaped galvanized bolts 11 allow the lifting slings to pass through during lifting of the placement frame 1, preventing the slings from falling off and improving safety during transport.

[0037] The support assembly is mounted on the placement frame 1 and serves to support the placement frame 1 and connect the two lifting brackets. The support assembly consists of three sets of support frames. Each set includes two lower supports 21 and two upper supports 22. Both lower supports 21 and upper supports 22 are made of 400mm×40mm×25mm, 3mm thick aluminum square tubing, and are fixed to both sides of the placement frame 1 by welding to connectors, thus supporting the placement frame 1. A total of twelve aluminum square tubing are used, each with four 10mm diameter holes at both ends, serving as connection holes for the two lifting brackets. The two lifting brackets can be assembled and used using bolts. Specifically, the lifting brackets can be used independently (e.g., Figure 5 As shown), it can also be adopted as follows: Figure 6 Two hoisting brackets are stacked and connected, or as follows: Figure 7 The two hoisting brackets shown are connected side by side. The specific assembly method is not limited here. You can choose the appropriate assembly method according to the actual situation.

[0038] The fastening assembly, consisting of two clamps, is mounted on the mounting frame 1 and is used to secure the underwater vehicle 4. For example... Figure 3-4 As shown, each clamp consists of an upper clamp 31 and a lower clamp 32, both made of 4mm aluminum plate. The lower clamp 32 is fixed to the mounting frame 1 by welding. The upper clamp 31 is connected to the lower clamp 32 by a filler block 33 and a wing bolt 34. The upper clamp 31 and the lower clamp 32 together enclose and clamp the underwater vehicle 4. The filler block 33 is replaceable and is used to adjust the clamping force of the upper clamp 31 and the lower clamp 32 to ensure clamping stability. At the same time, a felt protective layer is provided on the inner wall of the upper clamp 31 and the lower clamp 32 to protect the surface of the underwater vehicle 4 and prevent damage to the underwater vehicle 4.

[0039] When using this auxiliary tool, loosen the wing bolt 34, remove the upper clamp 31, place the underwater vehicle 4 into the lower clamp 32, and finally replace the upper clamp 31, tightening it with the wing bolt 34. After the underwater vehicle 4 is installed, the lifting rope passes under the placement frame 1, through the U-shaped galvanized bolt 11, and can be transported using a lifting device.

[0040] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
