Description

Technical Field

[0001] This invention belongs to the field of trolley frame welding and assembly technology, specifically the manufacturing process of an integrated computer room trolley. Background Technology

[0002] The machine room trolley used for container loading and unloading at a conventional terminal has a frame structure and a machine room enclosure structure that are two separate components with unrelated dimensions, resulting in a relatively large footprint for the machine room trolley.

[0003] The relevant reference CN117464222A discloses a small car frame manufacturing and assembly process, which divides the small car frame into six components for separate manufacturing and then splicing. However, there is a large deviation when assembling the common base, resulting in poor working performance of the small car frame. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a manufacturing process for an integrated data center trolley that reduces the footprint of the data center trolley and ensures that the working performance of the trolley frame is consistently good.

[0005] To address the above technical problems, this invention provides a manufacturing process for an integrated data center cart, comprising the following steps: Step 1: Make the small car frame; The trolley frame is divided into an anchored side and a non-anchored side. A horizontal wheel bracket is installed on the anchored side of the trolley frame. Bolt holes are drilled between the horizontal wheel bracket and the trolley frame. The trolley frame is constructed using a reverse-engineering method. Step 2: Construct the main frame of the computer room and connecting columns; The main frame of the computer room is mainly composed of H-beams and steel pipes; the H-beams are assembled into square frame panels, and the H-beam panels in the middle of the frame panels are welded together by connecting seats. The H-beam panels at the four corners of the frame panels are butt-welded; the steel pipes and connecting plates are assembled into groups, and the groups are installed on the bottom of the frame panels; the connecting plate parts are perforated. Step 3: Construct the chassis; The intermediate I-beam structure, front and rear longitudinal beams, and chassis are welded sequentially onto the jig; then the chassis and jig are flipped over together, and patterned plates are welded onto the chassis; finally, a common base is installed on the chassis. Step 4: Assemble the chassis and main frame of the computer room; Temporary support channel steel is installed on the chassis, with a height of 2100m. The main frame of the computer room is hoisted onto the chassis, and its height and horizontal position are determined. Horizontal diagonal braces are installed at the four corners of the square frame of the main frame of the computer room. Step 5: Construct the enclosure for the computer room; Step Six: Fabricate the driver's cab gantry; Step 7: Structural Assembly; Install upper supports on one long side of the main frame of the computer room and lower supports on one long beam of the chassis; Install the computer room enclosure, driver's cab hanger, and trolley frame sequentially on the main frame of the computer room; assemble the upper and lower connecting seats and upper and lower supports of the driver's cab hanger; adjust the driver's cab hanger to be level according to the chassis level, and weld the hinge shaft after adjustment; Based on the horizontal dimensions of the main frame of the computer room, mark the column trimming lines, trim the allowance, and assemble the left and right side trolley frames. Since the trolley frames are eccentric to the columns, diagonal braces need to be connected to the bottom of the trolley frames on the columns to adjust the level and center positioning of the trolley frames. After welding, check whether the level and allowance meet the processing requirements. The trolley frames are welded to the top of the columns. Pay attention to the position of the anchoring side during assembly.

[0006] By adopting the above technical solution, the trolley frame and the computer room wall are integrated into a single structure, connected by columns and connecting braces. The driver's cab hanger is connected to the chassis via a hinge shaft. This not only meets the installation accuracy requirements of the computer room trolley but also takes into account the dimensions of the computer room wall. Compared with the traditional two separate components, the trolley frame and the computer room wall, whose dimensions are not related, this solution greatly reduces the floor space required.

[0007] Preferably, in step two, the column is adjusted to be vertical during installation; a 250mm allowance is left at the top for slow welding when the column is assembled; temporary supports are installed on the column; the column is installed on the connecting seat of the main frame of the computer room; and a 50mm trimming allowance is left at the top of the column.

[0008] By adopting the above technical solution, the column can be installed stably while facilitating the assembly of the trolley frame.

[0009] Preferably, in step three, when fabricating the intermediate welded I-beam structure, the panel bevels are all facing upwards, and the fabrication is carried out on the jig. After straightening, the beam is welded, leaving a 200mm gap at both ends for delayed welding.

[0010] By adopting the above technical solutions, the welding angle and speed can be better controlled, the uniformity of the weld can be improved, the generation of welding defects can be avoided, and the 200mm delay in welding provides convenience for subsequent operation and maintenance.

[0011] Preferably, in step three, the front and rear longitudinal beams are I-beam structures. When manufacturing this I-beam structure, the connecting plates are assembled in bulk and do not participate in the splicing. The web and connecting plates are assembled and welded in the center, and the splicing seams are fully penetrated welded.

[0012] By adopting the above technical solution and using I-beams to make longitudinal beams, the load pressure can be better distributed and borne, reducing material waste while ensuring structural strength.

[0013] Preferably, in step three, when installing the common base, the positioning line of the common base is drawn with the center of the chassis as the reference. Position and install the first layer of the common base, hoist the first layer base, add temporary support L100*10 angle steel between the reducer bases, check the dimensions and hard stop correspondence, adjust the level, report the pre-welding dimensions, and weld after passing the inspection, welding first in the middle and then symmetrically welding to both sides. Position and install the second layer of the common base, remove the temporary support of the first layer, check the size and the corresponding hard block, adjust the level, weld the middle first and then weld symmetrically to both sides, do not weld the baffle and pad of the second layer base.

[0014] By adopting the above technical solution and using a structure with two common bases installed on the chassis, the lifting load can be effectively distributed and borne, further enhancing the load-bearing capacity of the trolley frame, ensuring the continuous good working performance of the trolley frame, and improving the service life of the computer room trolley.

[0015] Preferably, in step five, the computer room enclosure is mainly composed of four walls and a roof. The walls include 1.5mm corrugated plates and square tubes, with the square tubes located at the four corners. The 1.5mm corrugated plates are installed between pairs of square tubes and are laser welded. The roof structure is made of 3mm corrugated plates and square tubes welded together. The bottom of the computer room enclosure is sealed with 2mm bent plates.

[0016] By adopting the above technical solutions, corrugated plates are used in combination with square tubes to manufacture the computer room walls, which effectively prevents fire and moisture, improves the service life of the computer room trolley, and effectively controls structural deformation by using laser welding.

[0017] Preferably, in step six, the driver's cab hanger mainly consists of an upper connecting seat, a lower connecting seat, a pipe support, and a driver's cab connecting frame; the upper connecting seat is machined with a reamed hole and is only tack welded to the pipe support, and is welded during final assembly; the lower connecting seat is drilled with the driver's cab connecting frame; the two driver's cab connecting frames are connected by a connecting pipe, and a pipe support is installed on the top surface of the driver's cab connecting frame.

[0018] By adopting the above technical solution, the driver's cab hanger is formed by combining the upper and lower connecting seats, pipe supports, and driver's cab connecting frame, which effectively fixes and supports the driver's cab, ensuring the stability and safety of the driver's cab during operation, ensuring the safety of the driver's working environment, and enabling the driver to complete the operation tasks efficiently.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The trolley frame and the machine room wall of this invention are integral structures, connected by columns and diagonal braces in the middle. The driver's cab hanger is connected to the chassis by a hinge shaft. This satisfies the installation accuracy of the trolley frame while also taking into account the size of the machine room wall. Compared with the traditional trolley frame and machine room wall, which are two separate components with unrelated dimensions, this invention greatly reduces the footprint of the machine room trolley.

[0020] 2. The present invention adopts a structure in which two common bases are installed on the chassis, which can effectively distribute and bear the lifting load, further enhance the load-bearing capacity of the trolley frame, ensure the continuous good working performance of the trolley frame, and improve the service life of the computer room trolley.

[0021] 3. This invention uses corrugated plates combined with square tubes to manufacture the computer room enclosure, which effectively prevents fire and moisture, improves the service life of the computer room trolley, and uses laser welding to effectively control structural deformation.

[0024] The manufacturing process of the integrated data center vehicle includes the following steps: Step 1: Making the small car frame like Figure 1 , 2 As shown, the trolley frame 1 is divided into an anchored side and a non-anchored side. A horizontal wheel bracket 22 is installed on the trolley frame 1 on the anchored side 23. The horizontal wheel bracket 22 and the trolley frame 1 are fitted with bolt holes.

[0025] The trolley frame 1 adopts a reverse construction method, and high and low jig frames need to be made according to the structural form. The base plate is used as a reference, and the high and low jig frames are fixed to the top plate; the base plate is spliced ​​and welded, and the partition plate lines and side plate lines are marked on the structural surface of the base plate bevel; the partition plates and side plates are positioned and assembled; the side plate bevels are welded on the structural surface, first vertical fillet welds and then horizontal fillet welds.

[0026] Assemble one side of the bearing housing 21. The bearing housing 21 is pre-machined in a paired configuration, with the holes left with allowance for integral drilling and finishing during final assembly. The bearing housing 21 is positioned according to the structural centerline. Assemble the motor base support assembly. Weld full-penetration welds at the bevels at both ends of the side plate. Position and weld the side plate and the other side of the bearing housing 21. The bearing housing 21 needs to be positioned and installed according to the already installed bearings to prevent excessive concentricity differences, which could result in insufficient allowance for integral machining of the bearing holes. Install the sealing plate, buffer support tube, and other loose components.

[0027] After welding, the overall dimensions are straightened using heat straightening. The bearing housing 21 is checked to ensure it still meets machining requirements. A center crosshair is drawn for subsequent reference. The trolley frame structure is adjusted for horizontal and vertical alignment. The motor base is assembled and welded. The motor base pad is not welded initially; its dimensions will be measured after final assembly, and the material will be processed according to the actual requirements.

[0028] Step 2: Construct the main frame of the computer room and connecting columns. like Figure 3 As shown, the main frame 3 of the computer room is mainly composed of H-beams 8 and steel pipes 10. To reduce the amount of assembly and welding, the H-beam structure is first welded in groups to prevent large deformations and uncontrollable dimensions during assembly. The H-beams 8 are assembled into square frame panels. The H-beam 8 panels in the middle of the frame panels are welded together by connecting seats 12, and the H-beam 8 panels at the four corners of the frame panels are butt-welded. Holes are drilled on the long side of the H-beam 8 panels of the frame panels on site. Horizontal diagonal braces 11 are installed on the frame panels, and holes are drilled in the horizontal diagonal braces 11 and diagonal brace connecting plates. The four horizontal diagonal braces are numbered 1, 2, 3, and 4, and steel stamps are stamped on the corresponding diagonal brace connecting plates. Steel pipes 10 and connecting plates 9 are grouped together and installed on the bottom surface of the frame panels; holes are drilled in the connecting plates 9.

[0029] Check dimensions and positioning; prepare for welding and assemble the extinguishing plate; the overall welding requirements are to weld symmetrically from the inside out and on both sides of the center; the butt joint of the H-beam 8 panel should have full penetration (UT100%); after assembly, first complete the butt joint of the panels at the four corners; then weld the middle beam: the butt joint of the H-beam 8 panel and the connecting seat 12; then weld the corner welds at the four corners of the frame body; then weld the corner welds at the intersection of the middle beam 23 from the inside out; horizontal correction.

[0030] like Figure 4As shown, during installation, column 2 is adjusted to be vertical; a 250mm allowance is left at the top for welding during column 2 assembly; temporary supports are installed on column 2, and column 2 is welded to the temporary supports. A 50mm trimming allowance is left at the top of column 2, which will be trimmed according to the actual horizontal level when installing the trolley frame 1. Column 2 is installed on the connecting seat 12 of the main frame 3 of the computer room, ensuring stable installation while facilitating the assembly of the trolley frame 1.

[0031] Step 3: Making the chassis like Figure 5 As shown, the chassis structure is mainly a welded I-beam structure. The I-beams are first made in groups, then assembled and welded as a whole by marking lines. The I-beams are assembled and joined using ceramic gaskets. Note that the bevels should all face upwards during assembly.

[0032] group: The intermediate welded I-beam structure and the front and rear longitudinal beams were fabricated on a horizontal jig. The panel bevels were all facing upwards, and welding only began after straightening. A 200mm delay was left at both ends of the beams to better control the welding angle and speed, improve weld uniformity, and prevent welding defects. This 200mm delay at both ends also facilitated subsequent operations and maintenance. When fabricating the front and rear longitudinal beams, the connecting plate 9 was assembled loosely and not involved in the splicing process. The web plate and connecting plate 9 were centrally assembled and welded, with full penetration welding at the splicing seams. Using I-beams for the longitudinal beams better distributed and absorbed the load, reducing material waste while ensuring structural strength. After the group completed the fabrication, the beams were numbered according to the group drawings, corrected after welding, and submitted for quality control inspection.

[0033] Assembly: Fabricate a jig frame with a height of 800mm and a flatness of 2mm. Mark the center line and positioning line of the jig frame for easy assembly and positioning.

[0034] Underframe fabrication: Marking lines based on the center line, checking the numbering of the intermediate welded I-beams, positioning the long beams on the driver's cab side, and adjusting the horizontal and vertical alignment of the long beams; assembling the intermediate crossbeams, according to the group number, assembling from the inside out, with all bevels facing upwards; checking the joints of all beams, verifying dimensions and positioning, preparing for welding, and assembling the extinguishing plate. The jig frame is welded and fixed to the chassis structure 4; the overall welding requirements are from the inside out, symmetrically welding from both sides of the center; the panel butt joints of the I-beams must be fully penetrated (UT100%); after assembly, first complete the panel butt joints at the four corners of the underframe; then weld the butt joints of the intermediate beam panels, then weld the vertical corner welds at the four corners of the underframe, then weld the vertical corners at the intersections of the intermediate beams from the inside out, turn over and weld the flat corner welds between the web and the upper panel, and weld the remaining welded components.

[0035] First, prepare the patterned steel plate and flat steel in groups, adjust the plane, and then install and weld them into the base plate 4. The patterned steel plate needs to be placed obliquely into the base frame using a suction cup. Before welding, the structural base frame and jig are welded and fixed, and the welding sequence is symmetrical from the middle to both sides.

[0036] Install the common base: Draw the structural center line and structural horizontal line. Draw the positioning line of the common base 13 with the center as the reference. Check the fixation of the jig frame and chassis 4 structure. It is necessary to ensure that the jig frame and chassis 4 structure are welded and fixed. Position and install the first layer of common base 13. Hoist the first layer base and add temporary L100*10 angle steel supports between the reducer bases. Check the dimensions and hardened sections for correspondence, adjust the level, and report the pre-welding dimensions. After passing inspection, weld the common base 13, welding the middle first and then symmetrically to both sides. Position and install the second layer of common base 13. Remove the temporary supports of the first layer, check the dimensions and hardened sections for correspondence, adjust the level, and weld the second layer of common base 13, welding the middle first and then symmetrically to both sides, following the above steps. Report the pre-welding dimensions for inspection, and after passing inspection, weld. Note that the baffle and pad of the second layer base are not welded. After the final assembly, measure the dimensions, then cut and process the materials before welding. The structure of installing two layers of common base 13 on the chassis 4 can effectively distribute and bear the lifting load, further enhancing the load-bearing capacity of the trolley frame 1, ensuring the continuous good working performance of the trolley frame 1, and improving the service life of the machine room trolley.

[0037] After the two drum bases are completed and processed, they are assembled and welded onto the chassis 4.

[0038] Step 4: Assemble the chassis and main frame of the computer room. Temporary support channel steel, 2100m high, is installed on chassis 4. Diagonal bracing is required on both sides of the temporary support for protection. (For example...) Figure 6 As shown, the main frame 3 of the computer room is hoisted onto the chassis 4, and its height and horizontal position are determined. After removing the temporary supports, the horizontal diagonal braces 11 at the four corners of the square frame of the main frame 3 of the computer room are installed. The dimensions before welding are inspected and verified. After passing the inspection, welding is performed, the structural center line and horizontal line are marked, and the dimensions are re-measured.

[0039] Step 5: Construct the computer room enclosure like Figure 7 As shown, the computer room enclosure 6 mainly consists of four walls and a roof. The walls include 1.5mm corrugated steel sheets and square tubes, with the square tubes located at the four corners. The 1.5mm corrugated steel sheets are installed between pairs of square tubes using laser welding. The roof structure is constructed from 3mm corrugated steel sheets and square tubes. A 1.001mm shrinkage allowance is added to the computer room enclosure 6. The bottom of the computer room enclosure 6 is edged with 2mm bent steel sheets, temporarily reinforced with continuous square tubes or channel steel. The use of corrugated steel sheets combined with square tubes to construct the computer room enclosure 6 effectively prevents fire and moisture damage, extends the service life of the computer room trolley, and laser welding effectively controls structural deformation.

[0040] Step Six: Fabricate the driver's cab gantry like Figure 8As shown, the driver's cab hanger 5 mainly consists of an upper connecting seat 17, a lower connecting seat 18, a pipe support 19, and a driver's cab connecting frame 20; the driver's cab hanger 5 has a structural weight of 900 kg. The upper connecting seat 17 is machined with a reamed hole and only tack welded to the pipe support 19, with final welding during assembly. The driver's cab connecting frame 20 is fabricated by a team, and after completion, it is drilled to align with the lower connecting seat 18. The two driver's cab connecting frames 20 are connected by a connecting pipe, and the pipe support 19 is installed on the top surface of the driver's cab connecting frame 20. The upper and lower connecting seats, the pipe support 19, and the driver's cab connecting frame 20 are combined to form the driver's cab hanger 5, effectively fixing and supporting the driver's cab, ensuring the stability and safety of the driver's cab during operation, ensuring the safety of the driver's working environment, and enabling the driver to efficiently complete operating tasks.

[0041] Step 7: Structural Assembly like Figure 9 , 10 As shown, the assembly jig 7 is fabricated. The assembly jig 7 is 1000mm high and uses D400*8 supporting steel pipes. The horizontal requirement of the assembly jig 7 is ±2mm. Note the position of the auxiliary steel in the middle.

[0042] Assemble the upper support 14 based on the center reference. Note that the upper support 14 surface and the reamed hole are machined, painted before welding, and the reamed hole is coated with oil for protection. The upper support 14 is installed on one long side of the main frame 3 of the machine room. In this state, the connecting seat on the driver's cab hanger 5 needs to be welded, which will be difficult after the machine room enclosure 6 is installed; the lower connecting seat 18 only needs to be tack welded. The lower support 15 is installed on a long beam of the chassis 4.

[0043] The computer room enclosure 6 is installed on the main frame 3 of the computer room. First, the front and rear side walls are installed, then the left and right side walls are installed, and finally the roof is installed. The roof is assembled in bulk.

[0044] Note that the I-beam at position 2 of the roof support and the side of the wall need to be sealed with a 3mm corrugated board before the roof is installed, as this position is difficult to paint later.

[0045] The driver's cab hanger 5 is fitted with the upper support 14 and lower support 15 of the machine room. Material preparation: connecting hinge shaft, spacer, self-lubricating bearing (existing technology), and painting at the hinge point. The upper connecting seat 17 and lower connecting seat 18 of the driver's cab hanger 5 are fitted with the upper support 14 and lower support 15; adjust the level of the driver's cab hanger 5 according to the level of the chassis 4, and after the adjustment is completed, weld the hinge shaft through it, and wait for the auxiliary steel to be closed.

[0046] The trolley frame 1 is welded to the column 2. During assembly, pay attention to the position of the anchoring side 23. According to the horizontal dimensions of the main frame 3 of the machine room, mark the trimming lines of the column 2 and the connecting plate, trim the allowance, and assemble the left and right trolley frames 1. Since the trolley frame 1 is eccentric to the column 2, it is necessary to connect the diagonal brace 16 to the bottom of the trolley frame 1 on the column 2. Adjust the level and center positioning of the trolley frame 1. After welding, check whether the level and allowance meet the processing requirements.

[0047] Weld the base according to the horizontal and center reference. Measure the horizontal level of the main frame 3 of the machine room and the common base 13, and provide feedback on the cutting thickness of each pad; process the pads according to the actual dimensions, and then position and weld them.

[0048] The entire machine structure is punched, including the cross center punch of the machine room, the cross center punch of the trolley frame 1 bearing housing 21, and the structural center punch; the machining line of bearing housing 21 is drawn.

[0049] In this application, the trolley frame 1 and the computer room enclosure 6 are integral structures, connected by welding through the column 2 and the connecting diagonal brace 16. The driver's cab hanger 5 is connected to the chassis 4 by a hinge shaft. This not only meets the installation accuracy of the computer room trolley, but also takes into account the size of the computer room enclosure 6. Compared with the traditional two separate components, the trolley frame and the computer room enclosure, whose dimensions are not related, this greatly reduces the floor space occupied.

[0050] Bearing housing machining: After the overall welding is completed and inspected and approved, machining and scribing are performed to avoid the need for correction, repair and grinding work after machining.

[0051] Before marking the lines, calibrate the measuring instruments.

[0052] When marking lines, pay special attention to ensuring that the perpendicularity between the center line of the hinge point and the center line of the computer room structure is within the tolerance range.

[0053] The center lines of the hinge points are transferred to the non-machined surfaces to make four-point punches for easy inspection.

[0054] Draw the center lines of all hinge holes in one go, and try to do so within the same time period.

[0055] The diameter of the punch hole for machining scribing should be controlled within 0.2mm, and the scribing accuracy should be strictly controlled.

[0056] When scribing lines during machining, the work can only proceed after the work has passed inspection.

[0057] The four bearing housings 21 are machined using a single boring bar. Before machining, the coaxiality of the boring bar is measured to be less than 0.1 mm. The bearing housings 21 are mounted on the carriage frame 1.

[0058] After the machining is completed and passes inspection, the boring bar is removed, and the machined surfaces are coated with oil for protection.

[0059] Horizontal wheel support flange and shear block: Assemble the positioning horizontal wheel bracket 22. The horizontal wheel bracket 22 is fixed with a flange and is installed on the trolley frame 1 on the anchoring side 23 through the flange.

[0060] The horizontal wheel bracket 22 group completes the overall machining. The center of the reaming hole of the horizontal wheel bracket 22 is the center of the wheel. During assembly, the left and right directions are positioned according to this reference. The upper and lower positioning is based on the bearing seat center to the machining surface of the horizontal wheel bracket 22.

[0061] After positioning, weld the anti-shear blocks and drill holes. After removing the horizontal wheel bracket 22, drill and ream the holes.

[0062] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
