Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic supports for potash mines, and particularly to an assembly device and an assembly method for the roof beam of a hydraulic support for potash mines. Background Art

[0002] Currently, in the prior art, lithium salt mines are mostly mined by roadheaders. First of all, a roadheader is a highly complex device with high costs, and its installation and maintenance require a large amount of time. Secondly, a roadheader cannot flexibly adapt to changes in aspects such as the diameter of the tunnel, the trend of the tunnel axis, geological conditions, and lithology, which limits its application under different geological conditions. Thirdly, a large amount of heat is released during the operation of the roadheader, resulting in an increase in the working face environment temperature and requiring relatively large ventilation equipment.

[0003] Therefore, there are certain potential safety hazards in the process of lithium salt mine mining. Once a collapse occurs above the rock formation, it will cause personal safety accidents.

[0004] Therefore, it is necessary to support the top rock formation during the mining of lithium salt mines. The commonly used support equipment is a hydraulic support. The roof beam of the hydraulic support is in the form of a multi-component combination. During the combination, welding is carried out by manual positioning of workers, resulting in relatively low assembly efficiency. Summary of the Invention

[0029] In one technical solution of the present invention, in S4, welding the column socket to the top plate specifically includes:

[0030] S4.1: Switch the second tooling to the second positioning state to limit the position of the column socket relative to the first optical axis in the left - right direction; switch the third tooling to the third positioning state to limit the position of the column socket relative to the main reinforcement in the front - rear direction of the main reinforcement assembly;

[0031] S4.2: Weld the column socket.

[0032] Beneficial effects

[0033] The beneficial effects of the present invention are as follows: For the assembly device of the roof beam of the hydraulic support for potash mines of the present invention, the roof beam includes an inner main reinforcement assembly and an outer main reinforcement assembly, both of which are pre - assemblies, that is, after welding is completed to form modules, subsequent assembly and welding processes are carried out, which is beneficial to improving the assembly efficiency of the roof beam.

[0034] Each main reinforcement assembly includes a main reinforcement and a patch plate, and the outer main reinforcement assembly additionally includes ear plates. The patch plate is used to strengthen the strength of the main reinforcement to ensure the stability and reliability when connecting to the end of the hydraulic cylinder. The ear plate is a component extending from the main reinforcement for connecting to the end of the hydraulic cylinder. By setting the ear plate and the main reinforcement as a split structure, the cost of the outer main reinforcement assembly can be reduced and the assembly efficiency of the outer main reinforcement assembly can be improved.

The main reinforcement, the gusset plate, and the ear plate are respectively provided with first through holes, second through holes, and third through holes with parallel axes. The diameters of the first through hole and the second through hole are equal, which helps to ensure the alignment accuracy during assembly. The first tooling includes a positioning plate, a first optical axis, and a second optical axis. In the first positioning state, the gusset plate can be clamped between the positioning plate and the main reinforcement. The first optical axis passes through the positioning plate, the first through hole, and the second through hole, while the second optical axis passes through the positioning plate and the third through hole. In this way, the left-right position and the up-down position of the gusset plate and the ear plate relative to the main reinforcement are both limited. By fitting the ear plate and the gusset plate onto the main reinforcement, their front-back position relative to the main reinforcement is also limited, which can ensure that these ear plates and gusset plates can be accurately installed on the main reinforcement, improving the assembly accuracy of the outer main reinforcement component. It also reduces the possibility of incorrect assembly through precise positioning, thereby enhancing the safety and stability of the overall structure. Description of the Drawings

[0060] For better explaining the present invention for easy understanding, the following combines the attached Figures 1 - 10 , through specific implementation methods, describes the present invention in detail. Among them, the orientation nouns such as "upper" and "lower" mentioned in this article are based on Figure 1 the orientation for reference.

[0061] Example 1:

[0062] Refer to Figures 1 - 5, an embodiment of the present invention provides an assembly device for the top beam of a hydraulic support for potash mines. The top beam includes two sets of outer main reinforcement assemblies 1 and two sets of inner main reinforcement assemblies 2 arranged in parallel at intervals in the front-back direction. The two sets of inner main reinforcement assemblies 2 are located between the two sets of outer main reinforcement assemblies 1. Both the outer main reinforcement assembly 1 and the inner main reinforcement assembly 2 include a main reinforcement 121 and a backing plate 122. The outer main reinforcement assembly 1 further includes an ear plate 123. The main reinforcement 121, the backing plate 122, and the ear plate 123 are respectively provided with first through holes A, second through holes B, and third through holes C with parallel axes. The backing plate 122 and the ear plate 123 are respectively fixedly connected to the front side and the rear side of the corresponding main reinforcement 121. The diameters of the first through hole A and the second through hole B are equal. The assembly device includes a first tooling 3 for pre-assembling the outer main reinforcement assembly 1. The first tooling 3 includes a positioning plate 31, a first optical axis 32, and a second optical axis 33. The first tooling 3 can be switched to a first positioning state. In the first positioning state, the positioning plate 31 is horizontally supported on one side of the main reinforcement 121 corresponding to the outer main reinforcement assembly 1, and the corresponding ear plate 123 or backing plate 122 is located between the positioning plate 31 and the main reinforcement 121. The first optical axis 32 passes through the positioning plate 31, the first through hole A, and the second through hole B, and the second optical axis 33 passes through the positioning plate 31 and the third through hole C to define the positions of the ear plate 123 and the backing plate 122 on the outer main reinforcement assembly 1.

[0063] In this embodiment, the top beam includes an inner main reinforcement assembly 2 and an outer main reinforcement assembly 1, both of which are pre-assembled components, that is, they are first welded to form modules and then the subsequent assembly and welding processes are carried out, which is beneficial to improving the assembly efficiency of the top beam.

[0064] Each outer main reinforcement assembly 1 and inner main reinforcement assembly 2 includes a main reinforcement 121 and a backing plate 122, and the outer main reinforcement assembly 1 additionally includes an ear plate 123. The backing plate 122 is used to strengthen the strength of the main reinforcement 121 to ensure the stability and reliability when connecting to the end of the hydraulic cylinder. The ear plate 123 is a component extending from the main reinforcement 121 for connecting to the end of the hydraulic cylinder. By setting the ear plate 123 and the main reinforcement 121 as a split structure, the cost of the outer main reinforcement assembly 1 can be reduced and the assembly efficiency of the outer main reinforcement assembly 1 can be improved.

[0065] Under the action of the first tooling 3, the outer main reinforcement component 1 can be efficiently assembled. The main reinforcement 121, the patch plate 122 and the ear plate 123 are respectively provided with a first through hole A, a second through hole B and a third through hole C with parallel axes. The diameters of the first through hole A and the second through hole B are equal, which helps to ensure the alignment accuracy during assembly. The first tooling 3 includes a positioning plate 31, a first optical axis 32 and a second optical axis 33. In the first positioning state, the patch plate 122 can be clamped between the positioning plate 31 and the main reinforcement 121. The first optical axis 32 passes through the positioning plate 31, the first through hole A and the second through hole B, while the second optical axis 33 passes through the positioning plate 31 and the third through hole C. In this way, the left-right position and the up-down position of the patch plate 122 and the ear plate 123 relative to the main reinforcement 121 are both limited. By fitting the ear plate 123 and the patch plate 122 onto the main reinforcement 121, their front-back positions relative to the main reinforcement 121 are also limited. Furthermore, it can ensure that these ear plates 123 and patch plates 122 can be accurately installed onto the main reinforcement 121, improving the assembly accuracy of the outer main reinforcement component 1. It also reduces the possibility of incorrect assembly through precise positioning, thereby enhancing the safety and stability of the overall structure.

[0066] As for the degrees of freedom of rotation of the ear plate 123 and the patch plate 122 along the axes of the corresponding first optical axis 32 and second optical axis 33, they may not be limited. During the actual welding process, as long as it is ensured that the upper edge inspection surface of the ear plate 123 and the patch plate 122 does not protrude beyond the upper edge inspection surface of the main reinforcement 121, it can be manually corrected by the worker.

[0067] Specifically, when the ear plate 123 and the patch plate 122 are connected to the main reinforcement 121, the heights of their upper edges are kept less than the height of the upper edge of the main reinforcement 121 to ensure that their upper edges do not protrude beyond the main reinforcement 121, thereby ensuring that subsequent components including the top plate 4 can be conveniently and quickly installed.

[0068] Refer to Figures 1 - 10, the roof beam of the hydraulic support for potash mines further includes a roof plate 4, round steel 5, two sets of socket holes 6, two side plates 7, a plurality of rib plates 8 and a plurality of cover plates 9; an installation span is formed between adjacent outer main reinforcement components 1 and inner main reinforcement components 2; the two sets of socket holes 6 are fixedly connected to the two installation spans in a one-to-one correspondence; the two side plates 7 are fixedly connected to the front and rear sides of the roof plate 4 in a form parallel to the outer main reinforcement component 1 and the inner main reinforcement component 2, and both the outer main reinforcement component 1 and the inner main reinforcement component 2 are located between the two side plates 7; the rib plates 8 connect adjacent main reinforcements 121, as well as adjacent side plates 7 and main reinforcements 121; the round steel 5 extends in the front-rear direction and is fixedly connected to the ends of all main reinforcements 121 and side plates 7 that are farther away from the socket holes 6; a pitch is formed between adjacent inner main reinforcement components 2, between adjacent inner main reinforcement components 2 and adjacent outer main reinforcement components 1, and between adjacent side plates 7 and outer main reinforcement components 1. The cover plate 9 can be arranged in the pitch, the cover plate 9 corresponds to the pitch one by one, and can close the lower opening of the pitch; the cover plate 9 can be supported on the corresponding rib plate 8; a relief opening is formed on the cover plate 9 to make way for the vertical projection positions of the corresponding socket holes 6, backing plates 122 and ear plates 123.

[0069] Moreover, two additional ear plates 123 are connected to the roof plate 4 except for the ear plates 123 of the outer main reinforcement component 1, which can cooperate with the ear plates 123 of the two outer main reinforcement components 1 to form two ear plate modules. The axes of the third through holes C on the two ear plates 123 of each ear plate module coincide, so as to improve the bearing capacity when the ear plate module is connected to the hydraulic cylinder. Figure 10 The ear plate 123 in [] is the additional ear plate 123 on the roof plate 4.

[0070] In this embodiment, the two sets of socket holes 6 are respectively fixedly connected to the installation spans on both sides, ensuring the stability of the support points. At the same time, the socket holes 6 also provide a hardware foundation for the subsequent connection of the end of the hydraulic cylinder. Both the outer main reinforcement component 1 and the inner main reinforcement component 2 are located between the two side plates 7, forming a compact and strong frame structure. The rib plates 8 are used to connect adjacent main reinforcements 121 and the side plates 7 and main reinforcements 121, enhancing the strength and stability of the entire structure. A round steel 5 extends along the distribution direction of the outer main reinforcement component 1 and the inner main reinforcement component 2, firmly connecting all main reinforcements 121 and the ends of the side plates 7 away from the socket holes 6, further improving the rigidity of the overall structure. The cover plates 9 are specially designed to match the pitch and close the lower opening of the pitch. Each cover plate 9 can just be supported on its corresponding rib plate 8 and is specially designed with a relief opening to avoid the vertical projection positions of the socket holes 6, backing plates 122 and ear plates 123, so as to ensure the perfect combination of functionality and aesthetics, making the roof beam of the hydraulic support form a relatively closed structure, preventing foreign objects from invading, and improving the reliability of use of the roof beam. At the same time, the cover plates 9 can also be used as structural members to further improve the structural stability of the hydraulic support for potash mines.

[0071] Embodiment 2:

[0072] Referring to Figure 6 and Figure 7 , in addition to having all the technical solutions of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0073] The assembly device further includes a second tooling 10, and the second tooling 10 is arranged as an arch frame. The two ends of the second tooling 10 respectively form a clamping groove 1001 and a first matching portion 1002; the second tooling 10 can be switched to a second positioning state. In the second positioning state, the second tooling 10 straddles within the installation span in the left - right direction. The clamping groove 1001 can be matched with the first optical axis 32, and the first matching portion 1002 can be matched with the center of the column socket 6, so as to limit the position of the column socket 6 relative to the first optical axis 32 in the left - right direction, thereby ensuring the position accuracy of the column socket 6 in the left - right direction.

[0074] The assembly device further includes a third tooling 11, and the third tooling 11 is arranged as an arch frame; the two ends of the third tooling 11 respectively form two second matching portions 1101. The third tooling 11 can be switched to a third positioning state. In the third positioning state, the third tooling 11 straddles two installation spans in the front - rear direction of the outer main reinforcement component 1 and the inner main reinforcement component 2. The two second matching portions 1101 can respectively be matched with the centers of two groups of column sockets 6, so as to limit the position of the column socket 6 relative to the main reinforcement 121 in the front - rear direction of the outer main reinforcement component 1 and the inner main reinforcement component 2, thereby ensuring the position accuracy of the column socket 6 in the front - rear direction of the outer main reinforcement component 1 and the inner main reinforcement component 2.

[0075] The designs of the second tooling 10 and the third tooling 11 cleverly utilize the arch - frame structure and the specially designed matching portions, and utilize the first optical axis 32 of the first tooling 3, making the complex assembly process simpler and more precise, thereby effectively improving the assembly efficiency and quality.

[0076] At the same time, the second tooling 10 also undertakes the positioning component of the first tooling 3, that is, the first optical axis 32 of the first tooling 3, ensuring the continuity and relevance of the whole process, and further improving the assembly accuracy of the top beam.

[0077] Embodiment 3:

[0078] Referring to Figures 2 - 5 , in addition to having all the technical solutions of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0079] The first tooling 3 further includes a plurality of pin shafts 34, which are vertically and fixedly connected to the positioning plate 31; the pin shafts 34 are divided into two groups. One group of pin shafts 34 can be hung on the upper edge of the corresponding main reinforcement 121 to limit the degree of freedom of the positioning plate 31 to move up and down relative to the main reinforcement 121; the end faces of the other group of pin shafts 34 can abut against the corresponding main reinforcement 121 to limit the distance between the positioning plate 31 and the main reinforcement 121. Together with the first optical axis 32, the position of the positioning plate 31 relative to the main reinforcement 121 can be limited, thereby ensuring the positioning accuracy.

[0080] In this embodiment, one group of pin shafts 34 is designed to be hung on the upper edge of the corresponding main reinforcement 121. Through this design, the degree of freedom of the positioning plate 31 to move in the up and down direction relative to the main reinforcement 121 can be effectively limited, ensuring that the positioning plate 31 will not undergo unnecessary up and down displacement during use.

[0081] The end faces of the other group of pin shafts 34 are designed to be able to directly abut against the corresponding main reinforcement 121. This not only helps to limit the distance between the positioning plate 31 and the main reinforcement 121, ensuring that a constant distance is maintained between the two, but also limits the degree of freedom of the positioning plate 31 to swing along the up and down axis.

[0082] The first tooling 3 not only uses the positioning plate 31, the first optical axis 32 and the second optical axis 33 to limit the positions of the ear plates 123 and the attaching plates 122 on the outer main reinforcement assembly 1, but also further ensures that its relative position with the main reinforcement 121 remains fixed by arranging two groups of pin shafts 34, thereby ensuring the accuracy and stability of the entire assembly process.

[0083] Embodiment 4:

[0084] Referring to Figures 2 - 5 , in addition to having all the technical solutions of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0085] The positioning plate 31 is provided with a fourth through hole D and a waist-shaped hole E with parallel axes. The second optical axis 33 passes through the fourth through hole D and the third through hole C, and the first optical axis 32 passes through the waist-shaped hole E, the first through hole A and the second through hole B; the diameter of the waist-shaped hole E is larger than that of the first through hole A, and there is an interference fit between the fourth through hole D and the second optical axis 33 to ensure the connection stability and improve the connection accuracy.

[0086] In this embodiment, the diameter of the fourth through hole D is equal to the diameter of the third through hole C, which can ensure that the second optical axis 33 can smoothly pass through the fourth through hole D and the third through hole C to position the ear plate 123.

[0087] Both the waist-shaped hole E and the fourth through hole D are in clearance fit with the corresponding first optical axis 32 and second optical axis 33 to ensure that the first optical axis 32 and the second optical axis 33 can smoothly pass through the waist-shaped hole E and the fourth through hole D.

[0088] Meanwhile, the kidney-shaped hole E is arranged in a form extending vertically, avoiding over-positioning, so that the positioning plate 31 realizes vertical positioning only by hooking the pin shaft 34 on the upper edge of the main reinforcement 121, ensuring the assembly accuracy.

[0089] More specifically, there is an interference fit between the first optical axis 32, the kidney-shaped hole E, the first through hole A and the second through hole B, and there is an interference fit between the second optical axis 33, the fourth through hole D and the third through hole C. The interference fit can ensure the accuracy of the position limitation of the first optical axis 32 and the second optical axis 33 with respect to the attaching plate 122 and the ear plate 123, ensuring the positioning accuracy.

[0099] S2.1: Corresponding to the positions of the first through hole A and the second through hole B on the main reinforcement 121 and the attaching plate 122, two fifth through holes with the same diameter are opened. The diameter of each fifth through hole is smaller than that of the first through hole A;

[0100] S2.2: Machine the inspection surface of the ear plate 123, and open the third through hole C on the ear plate 123;

[0101] S2.3: Spot-fix the attaching plate 122 to the main reinforcement 121, and make the two fifth through holes coincide;

[0102] S2.4: Open the first through-hole A and the second through-hole B on the basis of the fifth through-hole;

[0103] S2.5: After switching the first tooling 3 to the first positioning state, weld the corresponding ear plates 123 and patch plates 122 of the outer main reinforcement component 1 to the corresponding main reinforcement 121 to complete the pre-assembly of the outer main reinforcement component 1;

[0104] Weld the patch plate 122 corresponding to the inner main reinforcement component 2 to the main reinforcement 121 to complete the pre-assembly of the inner main reinforcement component 2.

[0105] In S4, welding the column socket 6 to the top plate 4 specifically includes:

[0106] S4.1: Switch the second tooling 10 to the second positioning state to limit the position of the column socket 6 relative to the first optical axis 32 in the left-right direction; switch the third tooling 11 to the third positioning state to limit the position of the column socket 6 relative to the main reinforcement 121 in the front-back direction of the outer main reinforcement component 1 and the inner main reinforcement component 2;

[0107] S4.2: Weld the column socket 6.

[0108] Specifically, during assembly, three assemblies are required.

[0109] S1 - S3 is the first assembly. First, it is necessary to use the first tooling 3 to assemble and weld the inner main reinforcement component 2, and manually assemble and weld the inner main reinforcement component 2, and then weld the inner main reinforcement component 2, the outer main reinforcement component 1, the rib plate 8, the top plate 4 and the round steel 5 into an integral structure.

[0110] After the first assembly welding is completed, perform a shaping on the third through-hole C once to make it meet the requirements. Specifically, in this embodiment, when the top beam is in use, a shaft needs to pass through the third through-hole C. A optical axis can be inserted into the third through-hole C to measure the coaxiality. If the shaft cannot be inserted into the third through-hole C, it means that the deformation amount of the third through-hole C during the first assembly welding process exceeds the threshold. At this time, it is necessary to ream the third through-hole C to make it keep a clearance fit with the shaft.

[0111] S4 is the second assembly. At this time, it is necessary to assemble and weld two side plates 7 and two column sockets 6. When assembling and welding the column sockets 6, use the second tooling 10 to determine the left-right position of the column socket 6, use the third tooling 11 to determine the front-back position of the column socket 6, and use the top plate 4 to determine the up-down position of the column socket 6, so as to ensure the assembly and welding accuracy of the column socket 6 and improve the assembly convenience and assembly accuracy of the column socket 6.

[0112] After the second assembly welding is completed, perform a shaping on the third through-hole C again to make it meet the requirements. Similarly, a Insert the optical axis into the third through hole C to measure the coaxiality. If the shaft cannot be inserted into the third through hole C, it indicates that the deformation of the third through hole C caused by the first assembly and welding process exceeds the threshold. At this time, the third through hole C needs to be reamed to maintain a clearance fit with the shaft.

[0113] S5 is the third assembly, that is, assembling and welding the cover plate 9 and the side plate 7. The side plate 7 is welded on the outside of the outer main reinforcement assembly 1, between adjacent inner main reinforcement assemblies 2, between adjacent inner main reinforcement assemblies 2 and adjacent outer main reinforcement assemblies 1, and between adjacent side plates 7 and outer main reinforcement assemblies 1. The corresponding cover plate 9 is placed in the pitch and welded to the lower end of the rib plate 8 in the pitch to increase the structural strength of the top beam through the cover plate 9 and partially enclose the pitch.

[0114] After the third assembly and welding are completed, the third through hole C is re-shaped again. The specific method is the same as that of the first and second re-shaping methods, and will not be elaborated here.

[0115] In S6, the first through hole A and the second through hole B are processed into the sixth through hole G. In this embodiment, the first through hole A and the second through hole B are through holes, and they need to be processed into through holes to meet the requirement of passing the shaft. Moreover, since the sixth through hole G is processed after three weldings, the process of processing the sixth through hole G can balance the deviations and deformations of welding and assembly, and ensure the accuracy of the top beam.

[0116] The method is as follows:

[0117] S1: Positioning and marking of the top plate 4

[0118] Operating steps:

[0119] Place the top plate 4 stably on the special welding platform to ensure that the surface of the top plate 4 is flat and without inclination.

[0120] Use a laser locator or a precision scribing tool to draw assembly marking lines including the outer main reinforcement assembly 1 and the inner main reinforcement assembly 2 on the top plate 4. The marking lines need to be clearly visible to ensure the accuracy of subsequent component positioning.

[0121] The distance between the marking lines can also be checked with a vernier caliper or a laser rangefinder to ensure that it meets the requirements of the design drawing.

[0122] S2: Pre-assembly of the outer main reinforcement assembly 1 and the inner main reinforcement assembly 2

[0123] S2.1: Pre-processing of the through holes

[0124] On the main reinforcement bar 121 and the backing plate 122, at the preset positions corresponding to the first through-hole A and the second through-hole B, a fifth through-hole with a diameter smaller than that of the first through-hole A is machined. In this embodiment, the first through-hole A is The fifth through-hole is

[0125] S2.2: Machining of the ear plate 123

[0126] Machine the tool inspection surface of the ear plate 123, and drill a third through-hole C in the ear plate 123. The diameter of the third through-hole C is

[0127] S2.3: Temporary fixation of the backing plate 122

[0128] Place the backing plate 122 on the main reinforcement bar 121 so that the fifth through-holes of the main reinforcement bar 121 and the backing plate 122 coincide visually. Then, use spot welding to temporarily fix them, and 4 to 6 spot welds can be formed. Then, check the firmness of the spot welding to ensure no false welding or displacement.

[0129] S2.4: Reaming of the through-holes

[0130] Taking the fifth through-hole as the reference, expand the hole diameters of the main reinforcement bar 121 and the backing plate 122 to the design values to form the first through-hole A and the second through-hole B, that is, expand to Since this step is carried out after welding, the reaming process can eliminate the assembly error between the backing plate 122 and the main reinforcement bar 121, thereby ensuring the accuracy of the inner main reinforcement component 2 or the outer main reinforcement component 1.

[0131] S2.5: Welding of the outer main reinforcement component 1 and the inner main reinforcement component 2

[0132] The outer main reinforcement component 1 is assembled through the first tooling 3. Switch the first tooling 3 to the first positioning state, and the positioning plate 31 is fixed to the upper edge and side of the main reinforcement bar 121 through the pin shaft 34.

[0133] Place the ear plate 123 between the positioning plate 31 and the main reinforcement bar 121. The first optical axis 32 passes through the waist-shaped hole E, the first through-hole A, and the second through-hole B, and the second optical axis 33 passes through the fourth through-hole D and the third through-hole C. Since the first optical axis 32 and the second optical axis 33 have an interference fit with the corresponding holes, the stability of the assembly and welding process can be ensured, thereby further improving the assembly accuracy of the top beam.

[0134] When assembling and welding the inner main reinforcement component 2, directly weld the backing plate 122 to the main reinforcement bar 121 without the ear plate 123. The welding process is the same as that of the outer main reinforcement component 1, and the method of first temporary fixation and then opening the first through-hole A and the second through-hole B is adopted.

[0135] S3: Primary assembly and welding

[0136] Place the pre-assembled inner and outer main reinforcement components 1 on the top plate 4 according to the marked line position, and the rib plate 8 connects the adjacent main reinforcement 121 and the side plate 7 with the main reinforcement 121 in sequence. Use a clamp or manually fix the outer main reinforcement component 1 and the inner main reinforcement component 2 to the top plate 4 to prevent welding deformation. Weld the round steel 5 to the end of the outer main reinforcement component 1 and the inner main reinforcement component 2 away from the column socket 6, and ensure that the axis of the round steel 5 is parallel to the distribution direction of the outer main reinforcement component 1 and the inner main reinforcement component 2.

[0137] S4: Secondary assembly and column socket 6 positioning

[0138] S4.1: Positioning of column socket 6

[0139] The second tool 10 is straddled within the installation span, the card slot 1001 is matched with the first optical axis 32, and the first matching portion 1002 is aligned with the center of the column socket 6. The third tool 11 is straddled between the installation spans on both sides, and the second matching portions 1101 at both ends are matched with the centers of the two groups of column sockets 6 respectively. Since the second tool 10 cleverly uses the first optical axis 32 in this process, the positioning process is well connected to the one-time assembly process, ensuring the fluency and relevance of the entire assembly process, and improving the assembly efficiency and assembly accuracy.

[0140] S4.2: Welding of side plate 7 and column socket 6

[0141] Weld the connection between the side plate 7 and the top plate 4, and the connection between the side plate 7 and the rib plate 8.

[0142] The column socket 6 is welded to the top plate 4 and the main rib 121 adjacent to the column socket 6 .

[0143] S5: Three-stage assembly and welding of cover plate 9

[0144] The cover plate 9 is adjusted within the gear spacing to ensure that the upper and lower projections of the clearance opening and the column socket 6, the post plate 122, and the ear plate 123 are completely avoided to ensure the functional integrity of the ear plate 123, the post plate 122, the column socket 6 and other components. The lower end of the cover plate 9 is welded to the rib plate 8.

[0145] S6: Processing the sixth through hole G

[0146] Will the original The first through hole A and the second through hole B are expanded to This is to further eliminate assembly and welding errors and ensure that the final sixth through hole meets the use requirements.
