Therefore, the present embodiment provides a method for manufacturing an anchor recess structure to solve the above problems.
As shown in fig. 6, the method for processing the anchor recess structure includes: s1: respectively assembling a cylindrical cylinder small assembly 1, a horseshoe-shaped cylinder small assembly 2 and an anchor pit box small assembly 3, wherein one end of the horseshoe-shaped cylinder small assembly 2 is circular, and the other end of the horseshoe-shaped cylinder small assembly is obliquely arranged; s2: assembling the other end of the horseshoe-shaped cylinder small assembly 2 on the anchor recess box small assembly 3 to form an anchor recess combined small assembly; s3: one end of the horseshoe-shaped cylinder small assembly 2 is butted and assembled with the cylinder small assembly 1 to form an anchor recess structure.

Because the butt joint between one end of the small U-shaped cylinder assembly 2 and the small cylindrical cylinder assembly 1 is simple, and the assembly of the small U-shaped cylinder assembly 2 and the small anchor pit box assembly 3 is complex, the small U-shaped cylinder assembly 2 is assembled on the small anchor pit box assembly 3 to form the small anchor pit assembly, and then the small U-shaped cylinder assembly 2 is butt jointed with the small cylindrical cylinder assembly 1, so that the assembling difficulty is lower when the structure is larger and larger, the assembling difficulty and the workload can be reduced, and the working efficiency can be improved.
The three steps of the method for forming the anchor recess structure will be described in detail below.

Optionally, the parts of the small group 3 of anchor recess boxes include a top plate 31, a top sealing plate 32, a bottom plate 33, a lower sealing plate 34, a wear-resistant plate 35, round steel 36, a head-surrounding straight plate, a tail-surrounding straight plate and a head-tail curved bounding plate. The top plate 31 includes a top plate straight panel 311 and a top plate curved panel 312. To facilitate the processing of the top plate 31, the top plate straight panel 311 and the top plate curved panel 312 are first processed, and then the top plate straight panel 311 and the top plate curved panel 312 are assembled to form the top plate 31. Optionally, in this embodiment, round bar 36 is 200mm in diameter.
Roof 31, top shrouding 32, bottom plate 33 and shrouding 34 connect gradually the setting down, and antifriction plate 35 sets up under on shrouding 34, and round steel 36 sets up on bottom plate 33, and first straight board, the tail of enclosing encloses straight board and head and the tail curved surface bounding wall setting in the side of bottom plate 33 to form the cavity that can hold the anchor head.
First, the top plate 31, the top seal plate 32, the bottom plate 33, the lower seal plate 34, the wear plate 35, and the round bar 36 are processed, respectively. Wherein, the round steel 36 is U-shaped to match the small vertical column 2 of the horseshoe-shaped cylinder. The same as the parts for processing the cylindrical tube small assembly 1 and the horseshoe-shaped tube small assembly 2 is that the alignment line needs to be marked and installed in the process of processing each part of the anchor recess box small assembly 3. The center lines of the front and back surfaces of the top plate 31, the top sealing plate 32, the bottom plate 33, the lower sealing plate 34 and the wear plate 35 are respectively marked with a sixth mounting butt line, a seventh mounting butt line, a first mounting butt line, an eighth mounting butt line and a ninth mounting butt line so as to ensure accurate relative positions in the subsequent assembly process of each part.
Meanwhile, a head-surrounding straight plate, a tail-surrounding straight plate and a head-tail curved coaming are required to be processed. Optionally, it is also desirable to machine a first virtual jig parallel line on the leading edge flat plate and/or a second virtual jig parallel line on the trailing edge flat plate. The first virtual jig parallel line and the second virtual jig parallel line are both virtual straight lines, and can be used for finding and checking the installation angle of the small horse-shoe-shaped cylinder assembly 2 and the small anchor socket box assembly 3, which will be described in detail in step S2.
Alternatively, it is then necessary to assemble the various parts of the small group 3 of anchor recess boxes, including a series of welding operations. Firstly, the bottom plate 33 and the head surrounding straight plate are welded, and the bottom plate 33 and the tail surrounding straight plate are welded. The bottom plate 33 and the top plate 32 are then welded, and the top plate 32 and the top plate 31 are welded.

In the welding process, the small anchor pit box assembly 3 is firstly erected on the jig frame, and then the small anchor pit box assembly 3 is moved to the turnover jig frame to be turned over.
S2: and then assembling the small U-shaped cylinder assembly 2 on the small anchor recess box assembly 3 to form the small anchor recess assembly. Specifically, the horseshoe-shaped end of the horseshoe-shaped cylinder small assembly 2 needs to be welded with the lower sealing plate 34, the bottom plate 33 and the round steel 36 of the anchor recess box small assembly 3. Optionally, in this embodiment, the small horseshoe-shaped cylinder assembly 2 is tangential to the inner mouth of the round bar 36.
Before welding, an included angle between the axis of the horseshoe-shaped cylinder small assembly 2 and a first virtual jig parallel line or a second virtual jig parallel line of the anchor recess box small assembly 3 needs to be equal to a preset included angle, so that the assembly angle of the horseshoe-shaped cylinder small assembly 2 and the anchor recess box small assembly 3 is correct. Namely, when the included angle between the axis of the small assembly 2 of the horseshoe-shaped cylinder and the parallel line of the first virtual jig frame or the parallel line of the second virtual jig frame is equal to the preset included angle, welding is carried out. Optionally, in this embodiment, the preset included angle is 45 °.
Optionally, the specific welding steps of the small U-shaped cylinder assembly 2 and the small anchor recess box assembly 3 are as follows in sequence:

Wherein, the upper subsection and the lower subsection are both structures connected with the anchor recess structure on the ship body. And finally, assembling one end of the small U-shaped cylinder assembly 2 and one end of the small cylindrical cylinder assembly 1, which is not connected with the upper section, in a butt joint manner, so that the assembly of the anchor recess structure and other structures of the ship body can be completed while the assembly of the anchor recess structure is completed.
It should be noted that other welding process requirements of the anchor recess structure processing method include:
(1) The length of the tack weld is 50mm, and if the tack weld cracks or has unacceptable defects before or during welding, the cracked tack weld needs to be planed, and welding is carried out after the tack weld is reassembled.
(2) All fillet ends must be fillet welded.
(3) Before welding, whether the groove is clean or not, whether the tack welding quality meets the requirements or not, and whether dirt such as rust or garbage exists in the range of 50mm at the two edges of the groove or not need to be checked.
(4) Before the tack welding or the formal welding, the area to be welded needs to be preheated, and the preheating requirement is as follows:
a) When the temperature of the parent metal is lower than 0 ℃, preheating to 21 ℃ at least;
b) When the thickness of the base material is more than 20mm, preheating to 10 ℃ at least;
c) When the thickness of the base material is more than 38mm, preheating to 65 ℃ at least;
d) When the thickness of the parent metal is more than 65mm, preheating to 110 ℃ at least;
e) The preheating temperature for the welding repair is at least 120 ℃.
The welding requirements can ensure the welding quality of each part on the anchor recess structure so as to ensure the strength and quality of the anchor recess structure.

Because the butt joint between one end of the small U-shaped cylinder assembly 2 and the small cylindrical cylinder assembly 1 is simple, and the assembly of the small U-shaped cylinder assembly 2 and the small anchor recess box assembly 3 is complex, the small U-shaped cylinder assembly 2 is assembled on the small anchor recess box assembly 3 to form the small anchor recess assembly, then the small cylindrical cylinder assembly 1 is assembled on the upper subsection, the small anchor recess assembly is assembled on the lower subsection, and finally the small U-shaped cylinder assembly 2 is butt-jointed with the small cylindrical cylinder assembly 1, so that the assembly difficulty is lower when the structure is larger and larger, the assembly difficulty and workload can be reduced, and the working efficiency can be improved.
Because the assembly angle of the small U-shaped cylinder assembly 2 and the small anchor recess box assembly 3 directly influences the angle between the anchor chain moving direction and the anchor head moving direction, the deviation from the design angle can cause larger anchor head traction force and large energy loss, and the acting force between the anchor head moving process and the wall surface of the anchor recess is large, thereby causing the damage of the wall surface of the anchor recess, and the blocking of the traction of the anchor head. In the embodiment, the method for marking the virtual jig parallel lines is adopted, the assembling angle can be quickly found before welding, the verification can be quickly carried out after welding, the problems caused by the angle deviation can be quickly and conveniently solved, the excessive workload can not be increased, and the assembling efficiency can be ensured.
