Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding, and in particular to a method for hoisting pipe fittings in a ship's piping cabin. Background Art

[0002] There is a pipe compartment in the double bottom of the ship. During the segmentation stage, the pipes are usually stuffed into the pipe compartment after the segmentation structure is loaded. The environment inside the pipe compartment is small and the lifting equipment cannot directly lift the pipes into place, which increases the labor intensity of the operators. Summary of the Invention

[0003] In order to alleviate the problem of difficulty and high labor intensity in lifting pipe fittings in a pipe compartment, the present invention provides a method for lifting pipe fittings in a pipe compartment of a ship. The technical objectives of the present invention are achieved through the following technical solutions:

[0004] A method for hoisting pipe fittings in a ship's pipe compartment, the method comprising the following steps:

[0005] Step 1: Fix the cabin operation auxiliary tool on the cabin top, and provide a sliding hoist at the lower end of the cabin operation auxiliary tool that can move horizontally along the cabin operation auxiliary tool;

[0006] Step 2: Use lifting equipment to set up a lifting rope at each end of the pipe fitting and lift the pipe fitting;

[0007] Step 3: Move the pipe closer to the cabin, place one end of the pipe on the sliding hoist, and then untie the lifting rope on that end of the pipe;

[0008] Step 4: Move one end of the pipe into the cabin under the lifting of the sliding hoist until the lifting equipment at the other end of the pipe can no longer lift the pipe forward. Place the other end of the pipe on the sliding hoist and untie the lifting rope at the other end of the pipe.

[0009] Step 5: Pull the sliding hoist to lift the pipe into place.

[0010] Furthermore, in step 1, the cabin operation auxiliary tool includes a light I-beam and a fixing frame. The fixing frame is installed and fixed to the lower end of the cabin beam, and then the light I-beam is installed on the fixing frame, and the sliding hoist is installed at the lower end of the light I-beam.

[0011] Furthermore, the fixing frame structure used in step 1 includes a rectangular clamp, a crossbeam longitudinal plate, a crossbeam flat plate, and a reinforcing rib, one side of the crossbeam longitudinal plate is vertically connected to the crossbeam flat plate and the outer side wall of the rectangular clamp, and the opening direction of the rectangular clamp is facing the horizontal direction; one end of the reinforcing rib is clamped on the outer wall of the rectangular clamp, and the other end of the reinforcing rib is provided with an ear plate, and the ear plate is provided with an opening; the upper part of the rectangular clamp is provided with a threaded connection positioning bolt, and the crossbeam longitudinal plate is provided with a connecting hole.

[0012] Furthermore, in step 1, the beam plate is set on the upper end of the beam, the two fixing frames on the same side of the beam are connected and fixed by a first connecting member passing through the opening, and the fixing frames are connected and fixed by a second connecting member passing through the connecting hole.

[0013] Furthermore, two fixing frames are symmetrically provided on one side of the crossbeam, and two fixing frames are also symmetrically provided on the other side of the crossbeam, and the fixing frames on both sides are symmetrical with respect to the crossbeam.

[0014] The beneficial effect of the present invention is that by installing cabin operation auxiliary tools in the cabin, the auxiliary tools are used instead of lifting equipment to realize the lifting of pipes in the cabin, which solves the problem that the lifting equipment in the cabin cannot be used, reduces the labor intensity of lifting pipes in the cabin, and is convenient and quick.

[0020] The technical solution of the present invention is further described below in conjunction with specific embodiments:

[0021] A method for hoisting pipe fittings in a ship's pipe compartment, the method comprising the following steps:

[0022] Step 1. Fix the cabin operation auxiliary tool 5 on the top of the cabin. The cabin operation auxiliary tool 5 includes a light I-beam 6 and a fixing frame 7. Install and fix the fixing frame 7 on the lower end of the cabin's crossbeam 10, then install the light I-beam 6 on the fixing frame 7, and install the sliding hoist 3 on the lower end of the light I-beam 6 so that the sliding hoist 3 can move horizontally along the cabin operation auxiliary tool 5.

[0023] The structure of the fixing frame 7 in step 1 includes a rectangular clamp 71, a crossbeam longitudinal plate 72, a crossbeam flat plate 73, and a reinforcing rib 74. One side of the crossbeam longitudinal plate 72 is vertically connected to the crossbeam flat plate 72 and the outer side wall of the rectangular clamp 71, and the opening direction of the rectangular clamp 71 is facing the horizontal direction; one end of the reinforcing rib 74 is clamped on the outer wall of the rectangular clamp 71, and the other end of the reinforcing rib 74 is provided with an ear plate 75, and the ear plate 75 is provided with an opening 751; the upper part of the rectangular clamp 71 is provided with a threaded connection positioning bolt 76, and the crossbeam longitudinal plate 72 is provided with a connecting hole 721, as shown in FIG. Figure 3 shown.

[0024] When in use, the crossbeam plate 73 is mounted on the upper end of the crossbeam 10, and the first connecting member 8 is used to pass through the opening 751 to connect and fix the two fixing frames 7 on the same side of the crossbeam 10, and the second connecting member 9 is used to pass through the connecting hole 721 to connect and fix the fixing frames 7 on both sides of the crossbeam 10. On the same side of the crossbeam 10, the two fixing frames 7 are symmetrically arranged; the fixing frames 7 on both sides of the crossbeam 10 are also symmetrical about the crossbeam 10, as shown in FIG. Figure 4 shown.

[0025] Step 2: Use a lifting device 1 to set a lifting rope 2 at each end of the pipe 4 to lift the pipe 4;

[0026] Step 3: Figure 1 As shown, the lifting device 1 lifts the pipe 4 and brings it closer to the cabin. One end of the pipe 4 is first placed on the sliding hoist 3 in the cabin. Then, the lifting rope 2 on that end of the pipe is untied. At this time, one end of the pipe 4 is placed on the sliding hoist 3, and the other end of the pipe 4 is still lifted by the lifting device 1.

[0027] Step 4: One end of the pipe 4 is moved into the cabin under the lifting of the sliding hoist 3 until the lifting device 1 at the other end of the pipe 4 can no longer continue to lift the pipe 4 into the cabin. The other end of the pipe 4 is also placed on the sliding hoist 3, and the lifting rope 2 at the other end of the pipe 4 is untied. At this time, the lifting device 1 is separated from the pipe 4, and both ends of the pipe 4 are placed on the sliding hoist 3 in the cabin. Figure 2 As shown;

[0028] Step 5: Use the rope to pull the sliding hoist 3 to move the pipe 4 in the cabin and lift the pipe 4 into place.

[0029] This embodiment is only a further explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
