Description

Technical Field

[0001] The invention relates to a ballast iron disassembly and assembly device for a manned submersible, in particular to a lifting device used for the ballast iron disassembly and assembly of a manned submersible. Background Art

[0002] Manned submersibles are mainly used for underwater surveys, geological exploration, sample collection, pipeline maintenance, salvage and rescue missions, and are mainly driven by energy storage batteries. In order to minimize the energy loss of manned submersibles when sinking or surfacing, sinking / surfacing ballast iron is installed on the submersible as needed during each operation.

[0003] The installation area of ​​ballast iron is located on the belly on both sides of the center of gravity of the submersible. Therefore, the crane in the submersible cabin cannot directly lift the ballast iron from the top to the installation position for hanging. It is necessary to use a lifting device to lift from bottom to top to perform positioning and hanging operations.

[0004] Foreign countries use an external roller-type hand-operated lift. The advantage is that the transfer system stops at any position on the track without affecting the installation of ballast iron and does not require an additional power source. The operation is simple and only requires one or two operators. The disadvantage is that this solution is only suitable for the attachment of ballast iron of smaller weight, and must be operated in low sea conditions, requiring a large external operating space.

[0005] A small roller hydraulic lift is used in China. The submariner first places the lift in the lifting area on the side of the panel on the rail car, then lifts the ballast iron to the lift panel, and then pushes it to the bottom of the ballast iron hanging position by manpower, and then the hydraulic lift lifts the ballast iron for hanging. The advantages of this solution are simple operation, applicable to different types of submersibles, greater carrying capacity and less space requirements. The disadvantage is that it must be operated in low sea conditions, otherwise it requires the assistance of multiple people and is less safe. Summary of the invention

[0006] The present invention aims to provide a lifting device for disassembling and assembling ballast iron of a manned submersible, thereby providing a new solution for disassembling and assembling ballast iron of a manned submersible.

[0007] To achieve the above-mentioned purpose, the technical solution of the present invention is: a lifting device for disassembling and assembling ballast iron of a manned submersible, comprising a transverse movement assembly, a lifting assembly, a telescopic assembly, and a bracket assembly. The transverse movement assembly is connected to the lifting assembly on top to drive the lifting device to move transversely; the top of the lifting assembly is connected to the telescopic assembly to drive the telescopic assembly to lift and lower, so as to realize the rotation of the telescopic assembly at the top; a bracket assembly is installed at the end of the telescopic arm of the telescopic assembly to drive the bracket assembly to move forward and backward by driving the telescopic arm; and tightening bolts are provided on both sides of the bracket assembly to clamp the ballast iron box.

[0008] Furthermore, the transverse movement assembly is composed of a mounting bracket, a transverse movement turbine worm, a transverse movement screw and nut, and a roller device. The mounting bracket is connected to the frame of the rail car, and the transverse movement turbine worm is connected to the lifting assembly through the transverse movement turbine worm nut and the roller device.

[0009] Furthermore, the transverse movement of the worm gear is driven by a pistol drill or a ratchet wrench to drive the transverse movement screw to rotate, thereby driving the nut to move laterally, thereby realizing the transverse movement of the entire lifting device.

[0010] Furthermore, the lifting assembly consists of a two-stage lifting mechanism, a sprocket pair, a rotating turbine, and a reducer; the lifting assembly is fixed to the nut of the transverse movement device through the mounting interface on the side of the base, and the lifting mechanism contains a set of two-stage lead screw pairs, and the lead screw nut is connected to the outer bracket of the lifting mechanism; the reducer is connected to the driving sprocket of the sprocket pair, and the driven sprocket is connected to the end of the two-stage lead screw built into the lifting mechanism.

[0011] Furthermore, the pistol drill or ratchet wrench drives the reducer to drive the active sprocket, and the chain drives the driven sprocket, so that the screw nut pair hidden in the lifting mechanism rotates, thereby driving the lifting mechanism to complete the lifting and lowering movement.

[0012] Furthermore, a mounting bracket for the telescopic assembly is provided on the top of the lifting assembly, and is equipped with a set of rotating turbines. After assembly is completed, the rotation of the turbine drives the entire telescopic assembly to complete the rotational motion.

[0013] Furthermore, the telescopic assembly consists of a mounting seat, a fixed arm, a telescopic arm, and a rotating worm. The mounting seat is connected to the lifting assembly as a whole. The telescopic arm contains a telescopic screw and a nut. A mounting hole for the bracket assembly is reserved at the end of the telescopic arm.

[0014] The rotating worm is driven by a pistol drill or a ratchet wrench to realize the rotation movement of the telescopic assembly at the top; the driving head at the end of the fixed arm is driven by the ratchet wrench to drive the telescopic screw and the nut pair to rotate, thereby driving the telescopic movement of the telescopic arm in the fixed arm;

[0015] Furthermore, the bottom of the bracket bracket assembly has a concave structure, which can be assembled with the telescopic arm of the telescopic assembly and fixed as a whole by a latch.

[0016] Furthermore, the shape and size of the bracket in the bracket assembly are compatible with the ballast iron boxes of different submersibles.

[0017] The beneficial effects brought by the technical solution of the present invention are as follows:

[0018] 1) The lifting device is integrated into the rail car and is usually stored under the rail car without taking up space. It can be used at any position of the rail car when it is parked on the track as needed.

[0019] 2) Multiple degrees of freedom of movement can realize all the steps required for ballast iron installation. With different external brackets, it can adapt to the mounting of ballast irons of different sizes, weights and positions.

[0020] 3) Each degree of freedom of movement can be self-locking, which can provide safety in poor sea conditions.

[0021] 4) Only 1 to 2 operators are required, all using pistol drills or ratchet wrenches for easy operation, without additional power distribution. BRIEF DESCRIPTION OF THE DRAWINGS

The transverse moving worm gear 1.2 is driven by a pistol drill or a ratchet wrench to drive the transverse moving screw to rotate, thereby driving the nut to move horizontally, thereby realizing the transverse movement of the entire lifting device.

[0031] like Figure 3 As shown, the lifting assembly 2 is composed of a two-stage lifting mechanism, a sprocket pair, a rotating turbine, a reducer, etc. The lifting device is fixed to the nut of the transverse movement assembly 1 through the mounting interface on the side of the base. The lifting mechanism contains a set of two-stage lead screw pairs, and the lead screw nut is connected to the outer bracket 2.1 of the lifting mechanism. The reducer is connected to the active sprocket of the sprocket pair, and the driven sprocket is connected to the end of the two-stage lead screw hidden in the lifting mechanism. The reducer is driven by a pistol drill or a ratchet wrench to drive the active sprocket, and the driven sprocket is driven by the chain to rotate the screw nut pair hidden in the lifting mechanism, thereby driving the lifting mechanism to complete the lifting and lowering movement.

[0032] like Figure 4 As shown, the telescopic assembly 3 is composed of a mounting seat 3.1, a fixed arm 3.2, a telescopic arm 3.3, a rotating worm, etc. The mounting seat 3.1 is connected to the lifting assembly 2 as a whole, and the telescopic arm 3.3 contains a telescopic screw and a nut.
