Detailed Implementation

[0019] The fabrication process for the mounting supports of the tire crane steering mechanism is as follows: After the push rod support, locking pin cylinder support, and guide support are all machined and welded, they are integrally positioned and welded onto the balance beam. Specifically, according to the dimensional requirements of the design drawings, a marking operator and a welder work together. Using the machined holes and surfaces as a reference, straightedges, rulers, and measuring tapes are used for marking, positioning, and dimensional measurement, followed by spot welding. Measurements are repeated for verification before final welding. This work requires two skilled master craftsmen working together to complete.

[0020] However, because the dimensional quality control throughout the assembly process is entirely dependent on the skill level of the on-duty technicians, the work mode is inefficient, and the instability of personnel skills leads to inconsistent assembly quality. On-site assembly issues include dimensional deviations, component interference, and in some cases, rework.

[0021] Reference will now be made in detail to embodiments of the invention, one or more examples of which are illustrated in the accompanying drawings. Each example is provided to explain the invention and not to limit it. In fact, it will be apparent to those skilled in the art that various modifications and variations may be made to the invention without departing from the scope or spirit thereof. For example, a feature shown or described as part of one embodiment may be used with another embodiment to produce yet another embodiment. Therefore, the invention is intended to cover these modifications and variations that fall within the scope of the appended claims and their equivalents.

[0022] As used herein, the terms “first,” “second,” “third,” and “fourth” are used interchangeably to distinguish one component from another and are not intended to indicate the location or importance of the individual components.

[0023] As used in this article, the term "mobile crane" is a type of rotating boom crane that uses a tire-mounted chassis for mobility.

[0024] Figure 1 The structure of the tire crane traveling mechanism 10 is shown. (For example...) Figure 1As shown, the tire crane includes multiple traveling mechanisms 10. Each traveling mechanism 10 controls its direction of travel via a steering mechanism 20.

[0025] like Figure 2 As shown, the steering mechanism 20 includes a steering hydraulic cylinder 21, a steering linkage 22, and a locking pin cylinder 23.

[0026] based on Figure 2 The structure of the steering mechanism 20 shown is illustrated, and the corresponding mounting bracket for the steering mechanism 20 is used to install and fix the steering mechanism 20.

[0027] refer to Figure 4 The mounting supports for the steering mechanism 20 include a balance beam 1, a push rod support 2, a locking pin cylinder support 3, and a guide support 4. The push rod support 2, locking pin cylinder support 3, and guide support 4 are all mounted on the balance beam 1. The push rod support 2 is used to fix the fixed end of the steering hydraulic cylinder 21; the locking pin cylinder support 3 is used to fix the fixed end of the locking pin cylinder 23; and the guide support 4 guides the ejection end of the locking pin cylinder 23.

[0028] The entire steering process of the traveling mechanism 10 requires the action of the steering linkage 22 in the steering mechanism 20, which outputs thrust through the steering hydraulic cylinder 21. The fixed end of the steering hydraulic cylinder 21 is connected to the push rod support 2. The cylinder pushes out to rotate the tire, thereby enabling the tire crane traveling mechanism 10 to achieve the steering purpose.

[0029] Meanwhile, the fixed end of the locking cylinder 23 is fixed by the locking cylinder support 3, and the ejected end extends forward along the guide hole on the guide support 4 under the action of the guide support 4 to fix the angle of tire steering.

[0030] exist Figure 2 In the middle, the tire crane traveling mechanism 10 is in a straight-line state, and its traveling direction is the straight-line direction. The angle between the steering mechanism 20 and the straight-line direction is 0°.

[0031] exist Figure 3 In the middle, the tire crane traveling mechanism 10 is in a turning state, and its traveling direction is diagonal, requiring it to rotate to a preset turning angle.

[0032] After the push rod support 2, locking pin cylinder support 3, and guide support 4 are each positioned, they are all welded to the balance beam 1. Therefore, the positions of the push rod support 2, locking pin cylinder support 3, and guide support 4 on the balance beam 1 play a crucial role in the positioning and normal operation of the tire crane's steering mechanism.

[0033] Figure 5The present invention illustrates a positioning and welding apparatus for a tire-mounted steering mechanism mounting bracket. This positioning and welding apparatus is used to position the mounting bracket of the steering mechanism. The structural layout of the components requiring positioning and welding in this invention is as follows: Figure 6 As shown, the mounting supports for the steering mechanism 20 specifically include a balance beam 1, a push rod support 2, a locking pin cylinder support 3, and a guide support 4. All key assembly dimensions of these four structural components have been machined before positioning welding. After the push rod support 2, locking pin cylinder support 3, and guide support 4 have all been welded and machined, they are then integrally positioned and welded to the balance beam 1.

[0034] Figure 7 The combination of the steering mechanism 20 and the positioning welding equipment of the present invention is shown. Figure 5 and Figure 7 The positioning welding equipment of the present invention is used to position the push rod support 2, the locking pin cylinder support 3, and the guide support 4 on the balance beam 1. The positioning welding equipment includes a support base 100, an active side reference component 200, a driven side reference component 300, a push rod support positioning component 400, a locking pin cylinder positioning component 500, and a guide support positioning component 600.

[0035] The active-side reference member 200 is used to cooperate with one support ring 1a of the balance beam 1. The driven-side reference member 300 is used to cooperate with the other support ring 1b of the balance beam 1 to fix the balance beam 1 and achieve the positioning function of the balance beam 1.

[0036] The push rod support positioning component 400 cooperates with the push rod support 2 to position the push rod support 2 on the balance beam 1.

[0037] The locking pin cylinder positioning component 500 and the locking pin cylinder support 3 cooperate to position the locking pin cylinder support 3 on the balance beam 1.

[0038] The guide support positioning component 600 cooperates with the guide support 4 to position the guide support 4 on the balance beam 1.

[0039] The active side reference member 200 is fixed to the first surface 110 of the support 100, and the first surface 110 of the support 100 is provided with a transverse positioning groove 120 and a longitudinal positioning groove 130.

[0040] The driven side reference component 300, push rod support positioning component 400, locking pin cylinder positioning component 500, and guide support positioning component 600 are detachably engaged with the transverse positioning groove 120 and the corresponding longitudinal positioning groove 130, respectively, and are thus detachably connected to the support base 100.

[0041] The transverse positioning groove 120 and the longitudinal positioning groove 130 can quickly position the support ring or the mounting support of the steering mechanism 20 corresponding to the driven side reference part 300, the push rod support positioning part 400, the locking pin cylinder positioning part 500 and the guide support positioning part 600, which can speed up the positioning and welding process of the mounting support of the steering mechanism 20.

[0042] The positioning and welding equipment for the mounting bracket of the present invention also includes a tooling placement base. The tooling placement base is placed horizontally on the horizontal working platform 5 and adjusted to a suitable position for placing the support 100 so that the support 100 is placed horizontally on the horizontal working platform 5 as an installation reference for each component.

[0043] The support base 100 is used to mount the various positioning components and serves as the main reference. In one embodiment, the reference... Figure 5 The transverse positioning groove 120 on the support 100 extends along the length of the support 100 and is coaxially arranged with the active side reference member 200. The longitudinal positioning groove 130 extends along the width of the support 100 and is perpendicular to the transverse positioning groove 120. There are multiple longitudinal positioning grooves 130, which are spaced apart on the first surface 110 of the support 100.

[0044] Figure 8 An exploded view of the driven-side reference member 300, the support base 100, and the active-side reference member 200 fixed to the support base 100 is shown.

[0045] In one embodiment, the active-side reference member 200 includes an active-side positioning reference plate 210 and an active-side support base 220 for supporting the active-side positioning reference plate 210. The active-side positioning reference plate 210 is used to determine the center distance and mates with the mounting surface of the support ring of the balance beam 1 (the two are fixed in place).

[0046] The active side support 220 is fixed to the first surface 110 of the support 100. The active side positioning reference plate 210 is connected to the active side support 220. The surface of the active side positioning reference plate 210 has a first positioning groove 211 along the circumferential direction. The first positioning groove 211 is used to cooperate with the mounting surface step of a support ring 1a of the balance beam 1 to achieve positioning.

[0047] Continue to refer to Figure 3 In one embodiment, the driven-side reference member 300 includes a driven-side positioning reference plate 310 and a driven-side support base 320 for supporting the driven-side positioning reference plate 310. The surface of the driven-side positioning reference plate 310 has a second positioning groove 311 along the circumferential direction. The second positioning groove 311 is used to cooperate with the mounting surface step of the other support ring 1b of the balance beam 1 to achieve positioning.

[0048] A first positioning reference plate 340 is fixedly connected to the end of the driven side support 320. The first positioning reference plate 340 is provided with a transverse limiting groove (not shown) and a longitudinal limiting groove (not shown). The driven side reference member 300 also includes a plurality of first positioning reference blocks 330. The first positioning reference blocks 330 are used for positioning and engaging the driven side support 320 with the support 100. At least one first positioning reference block 330 can be embedded in the transverse positioning groove 120 and the transverse limiting groove, and at least one first positioning reference block 330 can be embedded in the longitudinal positioning groove 130 and the longitudinal limiting groove, so that the first positioning reference plate 340 and the support 100 are positioned and engaged, and then after the first positioning reference plate 340 is positioned on the support 100, the driven side support 320 can be fixed to the support 100. The fixed connection method between the driven side support 320 and the support 100 can be a bolt fastening connection.

[0049] like Figure 8 As shown, the first positioning reference plate 340 (i.e. Figure 8 The lower plane of the driven side support 320 has a transverse limiting groove and a longitudinal limiting groove for fixing the first positioning reference plate 340. The upper plane of the driven side support 320 has a circumferential boss 321, which can fix the driven side positioning reference plate 310 to the support ring 1b of the balance beam 1.

[0050] The driven side positioning reference plate 310 is used to determine the center distance and mates with the mounting surface of the support ring 1b. The operator can determine the corresponding longitudinal positioning groove 130 by measuring with a tape measure according to the design drawings of the balance beam 1, and then hoist the driven side reference component 300 as a whole onto the support seat 100, and fasten the first positioning reference plate 340 and the support seat 100 with bolts.

[0051] Since the positional relationship between the support rings 1a and 1b of different balance beams 1 is different, after the active side reference component 200 is fixed on the support ring 1a, the position of the driven side reference component 300 needs to be adjusted. Finally, through the fixed cooperation between the active side reference component 200 and the support ring 1a and the driven side reference component 300 and the support ring 1b, the positioning and welding equipment of the present invention is fixed and positioned on the balance beam 1.

[0052] Figure 9 An exploded view of the pushrod support positioning component 400 is shown. Figure 9 As shown, in one embodiment, the push rod support positioning component 400 includes a push rod bracket 410, a positioning plate 420, and a first positioning pin 430. The push rod bracket 410 is connected to the support base 100. The push rod bracket 410 serves as the mounting reference for the other components of the push rod support positioning component 400.

[0053] Positioning plate 420 is used to position the lug 2a of the push rod support 2 (reference)Figure 6 The horizontal center plane of the push rod support 410. The push rod support 410 is provided with a slot 411 for accommodating the positioning plate 420. The positioning plate 420 is rotatably connected to the push rod support 410 in the slot 411. After the push rod support 410 is assembled on the support base 100, the positioning plate 420 can be operably rotated to cooperate with the two lugs 2a of the push rod support 2.

[0054] The positioning plate 420 is provided with a positioning slot 421. The first positioning pin 430 can pass through the ear plate holes 2b of the two ear plates 2a of the push rod support 2 and the positioning slot 421, thereby fixing the positioning plate 420 and the ear plates 2a of the push rod support 2 to achieve positioning of the push rod support 2.

[0055] In this embodiment, the push rod support positioning component 400 further includes a rotating pin 440. The rotating pin 440 is used to fix the positioning plate 420 and rotate around it. The push rod bracket 410 is provided with a mounting hole for the rotating pin 440, used to install the rotating pin 440 and fix the positioning plate 420. One end of the rotating pin 440 (i.e. Figure 9 A cotter pin 450 can be inserted into the lower end of the rotating pin 440 to prevent the rotating pin 440 from moving. The positioning plate 420 can rotate around the central axis of the rotating pin 440 to facilitate positioning of the push rod support 2.

[0056] Continue to refer to Figure 9 In one embodiment, the push rod support positioning member 400 further includes a pin positioning plate 460 for positioning the first positioning pin 430. The pin positioning plate 460 is used to determine the position of the positioning pins for different types of products. The first positioning pin 430 connects the two lugs 2a of the push rod support 2 to the pin positioning plate 460.

[0057] The pin positioning plate 460 is provided with at least one first positioning pin hole 461 that is adapted to the first positioning pin 430, and the first positioning pin hole 461 and the ear plate hole 2b of the push rod bracket 410 are correspondingly provided. The pin positioning plate 460 and the push rod bracket 410 are connected. The push rod bracket 410 is also provided with a pin reference hole 412 that is adapted to the first positioning pin hole 461, and the area of ​​the pin reference hole 412 is larger than the area of ​​the first positioning pin hole 461. The first positioning pin 430 is fixed by passing through the first positioning pin hole 461 and the pin reference hole 412.

[0058] Considering the orientation of the ear plate 2a of the push rod support 2, two pin positioning plates 460 are symmetrically arranged on the push rod bracket 410 and fastened to the push rod bracket 410 with bolts. The pin positioning plates 460 are available in various models, which can be freely selected and combined by the operator according to the size requirements of the design drawings of the balance beam 1. The horizontal position of the first positioning pin hole 461 can be determined by the pin positioning plates 460.

[0059] Continue to refer to Figure 9 In one embodiment, the push rod support positioning member 400 further includes a height adjustment part 470 and a second positioning reference plate 480 connecting the height adjustment part 470 and the push rod bracket 410, with the height adjustment part 470 connected to the support base 100. In another embodiment, the second positioning reference plate 480 can be directly connected to the support base 100, eliminating the need for the height adjustment part 470.

[0060] In the embodiment where the push rod bracket 410 and the support base 100 are connected via the height adjustment part 470, the second positioning reference plate 480 is connected to the push rod bracket 410. The height adjustment part 470 includes a height adjustment block 471 and a third positioning reference plate 472 disposed at the first end 471a of the height adjustment block 471.

[0061] The height adjustment block 471 adjusts the height of the push rod support positioning component 400 according to the dimensional requirements of the design drawings of the balance beam 1. Various models of the height adjustment block 471 are available. Different models of the height adjustment block 471 have different heights.

[0062] The push rod support positioning component 400 also includes multiple second positioning reference blocks 491. The second positioning reference plate 480 and the second positioning reference blocks 491 can be optionally connected by bolts. Both the second positioning reference plate 480 and the third positioning reference plate 472 are provided with lateral limiting grooves and longitudinal limiting grooves.

[0063] like Figure 9 As shown, the transverse limiting groove 481 and the longitudinal limiting groove 482 of the second positioning reference plate 480 are perpendicular to each other, and their intersection point is the center of the second positioning reference plate 480. The number of second positioning reference blocks 491 can be selected as follows: Figure 9 The four shown.

[0064] Continue to refer to Figure 9 In this embodiment, at least one second positioning reference block 491 is embedded in the lateral limiting groove 481 of the second positioning reference plate 480 and the lateral limiting groove (not shown) of the third positioning reference plate 472, and at least one second positioning reference block 491 is embedded in the longitudinal limiting groove 482 of the second positioning reference plate 480 and the longitudinal limiting groove (not shown) of the third positioning reference plate 472, so that the second positioning reference plate 480 and the third positioning reference plate 472 are positioned and engaged, and then after the third positioning reference plate 472 is positioned on the second positioning reference plate 480, the height adjustment block 471 can be fixed to the push rod bracket 410.

[0065] In another embodiment, the height adjustment unit 470 further includes a fourth positioning reference plate 473 connected to the second end 471b of the height adjustment block 471. The push rod support positioning member 400 also includes a plurality of third positioning reference blocks 492. The fourth positioning reference plate 473 and the third positioning reference blocks 492 may be bolted together.

[0066] The fourth positioning reference plate 473 is provided with a lateral limiting groove 473a and a longitudinal limiting groove 473b. At least one third positioning reference block 492 is embedded in the lateral positioning groove 120 and the lateral limiting groove 473a of the fourth positioning reference plate 473, and at least one third positioning reference block 492 is embedded in the longitudinal positioning groove 130 and the longitudinal limiting groove 473b of the fourth positioning reference plate 473, so that the fourth positioning reference plate 473 and the support 100 are positioned and engaged, and then after the fourth positioning reference plate 473 is positioned on the support 100, the height adjustment block 471 can be fixed on the support 100.

[0067] like Figure 9 As shown, the transverse limiting groove 473a and the longitudinal limiting groove 473b of the fourth positioning reference plate 473 are perpendicular to each other, and their intersection point is the center of the fourth positioning reference plate 473. The number of third positioning reference blocks 492 can be selected as follows: Figure 9 The four shown.

[0068] Combining the two embodiments described above, the intersection centers of the grooves of the fourth positioning reference plate 473 and the third positioning reference plate 472 on the upper and lower sides of the height adjustment block 471 coincide with each other, and are installed to coincide with the intersection center of the groove of the second positioning reference plate 480 on the push rod bracket 410. They cooperate with the transverse positioning groove 120 and the longitudinal positioning groove 130 on the support seat 100 and are fastened together by bolts to realize the connection between the push rod support positioning component 400 and the support seat 100.

[0069] The position of the push rod support 2 is determined by sequentially passing the positioning pin 430 through the first positioning pin hole 461, the ear plate hole 2b, the positioning slot 421, and the ear plate hole 2b. The push rod support positioning component 400 can be adapted to push rod supports 2 facing different directions of the ear plate hole 2b, thus improving adaptability.

[0070] Figure 10 An exploded view of the locking pin cylinder positioning component 500 is shown. Figure 10 As shown, in one embodiment, the locking pin cylinder positioning component 500 includes a locking pin positioning support 510, a vertical plate 520, and a second positioning pin 530. The locking pin positioning support 510 is connected to the support base 100. The locking pin positioning support 510 is used to define the mounting reference surfaces of the locking pin cylinder support 3. The vertical plate 520 is vertically fixed to the locking pin positioning support 510. The locking pin positioning support 510 and the vertical plate 520 can optionally be welded together.

[0071] exist Figure 10 In this configuration, a vertical plate 520 is fixed below the locking pin positioning support 510. The vertical plate 520 is provided with a second positioning pin hole 540 that mates with the second positioning pin shaft 530, and the second positioning pin hole 540 and the ear plate hole 3b of the locking pin cylinder support 3 are correspondingly arranged. The second positioning pin shaft 530 is used to position the locking pin cylinder support 3 and the locking pin positioning support 510. The second positioning pin shaft 530 passes through the second positioning pin hole 540 and the ear plate hole 3b of the locking pin cylinder support 3, thereby fixing the vertical plate 520 and the ear plate 3a of the locking pin cylinder support 3 to achieve positioning of the locking pin cylinder support 3.

[0072] The two sides of the vertical plate 520 are machined parallel to and perpendicular to the locking pin positioning support 510. The center plane determined by the two side planes of the vertical plate 520 coincides with the center plane determined by the transverse limiting groove 511 on the locking pin positioning support 510. The central axis of the second positioning pin hole 540 provided on the vertical plate 520 on the locking pin positioning support 510 coincides with and is parallel to the center plane determined by the two side planes of the longitudinal limiting groove 512 on the locking pin positioning support 510.

[0073] The locking pin cylinder positioning component 500 is available in several models, all featuring a common locking pin positioning support 510. The difference lies in the vertical distance between the second positioning pin hole 540 and the locking pin positioning support 510. The locking pin positioning support 510 has a transverse limiting groove 511 and a longitudinal limiting groove 512. The fourth positioning reference block 550 can be bolted to the locking pin positioning support 510. The fourth positioning reference block 550 can be embedded into the transverse limiting groove 511 and the longitudinal limiting groove 512 of the locking pin positioning support 510, ensuring that the center of the locking pin positioning support 510 coincides with the intersection of the transverse positioning groove 120 and the longitudinal positioning groove 130 of the support seat 100. After positioning, the locking pin positioning support 510 and the support seat 100 are fixedly connected using bolts.

[0074] Figure 11 An exploded view of the guide support positioning component 600 is shown. Figure 11 As shown, in one embodiment, the guide support positioning member 600 includes a guide seat positioning support 610 and a guide rod. The guide seat positioning support 610 is connected to the support base 100 and is provided with a positioning hole. The guide seat positioning support 610 is used to determine the mounting reference surfaces of the guide support 4. The guide rod passes through the positioning hole and the center hole 4a of the guide support 4, thereby fixing the guide seat positioning support 610 and the guide support 4 to achieve positioning of the guide support 4. The guide rod connects the guide support 4 and the guide seat positioning support 610.

[0075] Based on the above embodiments, the positioning hole further includes a central positioning hole 611 and at least one waist-shaped positioning hole 612 located on the side of the central positioning hole 611. The guide rod includes a first guide rod 621 and a second guide rod 622. The first guide rod 621 passes through the central positioning hole 611 and a central hole 4a of the guide support 4 (e.g., Figure 6 As shown), the second guide rod 622 passes through the waist-shaped positioning hole 612 and another central hole 4a of the guide support 4, thereby enabling the first guide rod 621 and the second guide rod 622 to fix the position of the guide support 4.

[0076] Considering the direction of guide support 4, such as Figure 11 As shown, there are two waist-shaped positioning holes 612, which are symmetrically arranged on both sides of the central positioning hole 611.

[0077] In this embodiment, the first guide rod 621 is fixedly inserted into the central positioning hole 611 of the guide seat positioning support 610, and the axis of the central positioning hole 611 coincides with the transverse center plane. The second guide rod 622 is inserted into the waist-shaped positioning hole 612 on the left or right side of the central positioning hole 611. The insertion of the first guide rod 621, which mates with the central hole 4a, into the central positioning hole 611 can restrict the position of one of the central holes 4a of the guide support 4.

[0078] The second guide rod 622 is inserted into one of the waist-shaped positioning holes 612 to determine the horizontal position of the guide support 4.

[0079] Combination Figure 8 and Figure 11 The guide support positioning component 600 also includes a guide rod auxiliary positioning plate 630 for limiting the position of the first guide rod 621 and the second guide rod 622. The guide rod auxiliary positioning plate 630 is used to cooperate with the first guide rod 621 and the second guide rod 622 to visually verify the positional accuracy of the first guide rod 621 and the second guide rod 622.

[0080] Specifically, the guide rod auxiliary positioning plate 630 is fixed to the active side support 220 and is provided with guide rod grooves 631 that are adapted to the central positioning hole 611 and the waist-shaped positioning holes 612 on both sides. Then, after the first guide rod 621 passes through the central positioning hole 611 and one central hole 4a of the guide support 4, and the second guide rod 622 passes through one of the two waist-shaped positioning holes 612 and the other central hole 4a of the guide support 4, the guide rod grooves 631 can receive the first guide rod 621 and the second guide rod 622 (that is, the first guide rod 621 and the second guide rod 622 are respectively inserted into the corresponding guide rod grooves 631).

[0081] Optionally, the guide rod auxiliary positioning plate 630 is bolted to the active side support 220 and is used to detect and determine whether the positioning of the guide rod is accurate. The detection method is to visually inspect one side of the flat end of the first guide rod 621 and the second guide rod 622. Figure 11 Check whether the right side of the guide rod 621 and the reference edge of the guide rod groove 631 are in close contact without gap. If they are in close contact without gap, then the positioning of the first guide rod 621 and the second guide rod 622 is confirmed to be accurate.

[0082] Continue to refer to Figure 11 The guide seat positioning support 610 has a transverse limiting groove 613 and a longitudinal limiting step 614. The transverse limiting groove 613 is fitted with a fifth positioning reference block 640, which is embedded within the transverse limiting groove 613. The fifth positioning reference block 640 is fastened to the guide seat positioning support 610 by bolts. The center plane determined by the two sides of the transverse limiting groove 613 coincides with the center plane determined by the two sides of the transverse positioning groove 120 of the support seat 100. The longitudinal limiting step 614 is embedded within the longitudinal positioning groove 130 of the support seat 100. Operators can select the position of the guide support positioning component 600 by measuring and calculating the longitudinal positioning groove 130 of the support seat 100, based on the design drawings of the balance beam 1.

[0083] Figure 12 A support frame 700 of the positioning welding equipment of the present invention is shown. The support frame 700 and the support base 100 are fixedly connected, and its function is to place the support base 100 so that the positioning welding equipment is placed horizontally. Figure 12 As shown, the support frame 700 includes a support base plate 710 and two support uprights 720. The two support uprights 720 are vertically fixed to the support base plate 710 and are parallel to each other.

[0084] When using the positioning welding equipment of the present invention, first place the support frame 700 on the horizontal working platform 5 as follows. Figure 13 As shown. Then, invert the support base 100 onto the support frame 700, as... Figure 14 As shown. According to the design requirements and dimensions of the balance beam 1, the installation positions are determined on the support seat 100, and the driven side reference component 300, push rod support positioning component 400, locking pin cylinder positioning component 500, and guide support positioning component 600 are sequentially hoisted onto the corresponding installation positions on the support seat 100.

[0085] Since the horizontal height varies between different models of mounting brackets, adjustments must be made according to the dimensions specified in the drawings.

[0086] After all components are in place, tighten the bolts. Once assembly is complete, the mounting bracket can be assembled, positioned, and welded. Through the proper combination of these components, the assembly of the mounting bracket can be made more convenient and faster, and the assembly and positioning dimensions can be closer to the dimensions shown in the drawings.

[0087] The steps are summarized as follows: Step 1: Prepare a reference platform (marking platform) and place the positioning welding equipment on the reference platform; Step Two: The operator assembles the fixtures according to the dimensions specified in the blueprints and the actual conditions. Positioning is performed using the locating reference slots on the fixtures, and bolts are tightened. A reference platform is then used for verification to ensure the positioning dimensions match the drawings.

[0088] Step 3: Hoist the push rod support 2, locking pin cylinder support 3, and guide support 4 to their approximate positions above the balance beam 1. Hoist the positioning and welding equipment onto the balance beam 1 and fix it in place using the active side reference component 200 and the driven side reference component 300. At the same time, using the push rod support positioning component 400, locking pin cylinder positioning component 500, and guide support positioning component 600, the push rod support 2, locking pin cylinder support 3, and guide support 4 are quickly positioned by fitting them together through the reference holes and reference surfaces. They are then connected and fixed together using pins.

[0089] Step 4: Once the positioning is complete, positioning welding can begin.

[0090] The installation and use process of the positioning welding equipment of the present invention will be further described in detail below with reference to the accompanying drawings and the above embodiments: First, the structural dimensions and specifications of the mounting supports for the steering mechanism 20 are collected and summarized. Specifically, the dimensions of the balance beam 1 include the center distance and the step stop dimensions. The positioning dimensions of the push rod support 2 include the distance from the step plane to the center of the inner opening of the ear plate 2a, the inner opening of the ear plate 2a, the distance from the center of the step flange to the center of the ear plate 2a, and the distance from the centerline of the balance beam to the center of the ear plate. The positioning dimensions of the locking pin cylinder support 3 include the lateral center distance from the center of the step flange to the center of the hole in the locking pin cylinder support 3, the vertical distance from the plane of the step flange to the center of the hole in the locking pin cylinder support 3, and whether the center of the inner opening of one hole in the locking pin cylinder support 3 coincides with the centerline of the balance beam (support hole opening / center distance between two openings). The positioning dimensions of the guide support 4 include the distance from the center of the hole in the locking pin cylinder support 3 to the near end of the guide support 4 / the thickness of the guide support 4, and whether the axis of the center hole 4a of the guide support 4 coincides with the centerline of the locking pin hole. The mounting brackets are not limited to the dimensions and specifications summarized above. More models can be combined and used by adding longitudinal positioning grooves 130 and height adjustment blocks 471 of more models to the support 100.

[0091] After determining the dimensions and specifications of the mounting bracket, the support frame 700 is first placed on the horizontal working platform 5. This facilitates the rapid and efficient adjustment and placement of the entire positioning and welding equipment. Figure 13 As shown.

[0092] like Figure 14 As shown, the support base 100, together with other components (including the active side reference component 200 and the guide rod auxiliary positioning plate 630) are placed horizontally on the support frame 700, so that the component mounting reference plane is parallel to the horizontal adjustment reference plane.

[0093] Combination Figure 8 and Figure 14 The active side support 220 has a stepped arc that matches the active side positioning reference plate 210. The active side support 220 and the active side positioning reference plate 210 are fastened together by bolts using a hexagonal bolt washer assembly, so that the central axis of the active side positioning reference plate 210 coincides with the central plane of the active side support 220.

[0094] The upper plane of the active-side positioning reference plate 210 is parallel to the upper plane of the active-side support 220 and the first surface 110 of the support 100, maintaining a relatively fixed distance. This serves as a reference surface, facilitating height measurement and adjustment of other components. This ensures that the center of the active-side positioning reference plate 210 coincides with the reference center plane. Furthermore, it maintains a relatively fixed height difference between the positioning plane of the active-side positioning reference plate 210 and the mounting planes of other positioning components, facilitating subsequent measurement and adjustment.

[0095] Continue to combine Figure 8 and Figure 14 On the mounting plane of the support 100, transverse positioning grooves 120 (to determine the center plane) and longitudinal positioning grooves 130 (to determine the positions of other positioning components) are arranged according to the component design drawings. A reference measuring port 140 is designed on the side of the support 100 (e.g., Figure 8 As shown in the figure, this facilitates the measurement and selection of the position of the longitudinal positioning groove 130 by the operators. Two lifting lugs 150 are fixedly connected to the lower surface of the support base 100, which facilitates the overall lifting of the positioning welding equipment. When the operators assemble the positioning welding equipment, they only need to measure and determine the longitudinal positioning groove 130 to be installed, and then directly proceed with the installation to obtain the required center distance.

[0096] Figure 16 for Figure 15 A partially enlarged view of point A on the active-side reference component 200. Combined with... Figure 15 and Figure 16The active-side positioning reference plate 210 has a first positioning groove 211, forming a first step positioning surface 212 and a second step positioning surface 213, which respectively correspond to the step plane of the support ring mounting position of the balance beam 1. The first step positioning surface 212 and the second step positioning surface 213 of the active-side positioning reference plate 210 are matched and positioned with the inner side of the step of the support ring mounting position of the balance beam 1.

[0097] Combination Figure 8 , Figures 10 to 12 The assembly process of the driven side reference component 300 is as follows: First, the operator determines the flange center distance between the first support ring 1a and the second support ring 1b of the balance beam 1. Then, one longitudinal positioning groove 130 is measured and selected from multiple longitudinal positioning grooves 130 to determine the installation position of the driven side reference component 300. During the initial installation, the transverse limiting groove and longitudinal limiting groove on the lower surface of the first positioning reference plate 340 set below the driven side support 320 are fastened to the first positioning reference block 330 by bolts using hexagonal bolt and washer assemblies.

[0098] The driven side support 320 has a circumferential boss 321 on its upper surface. The center of the circumferential boss 321 coincides with the intersection of the transverse limiting groove and the longitudinal limiting groove of the first positioning reference plate 340. The circumferential boss 321 matches the stepped surface provided below the driven side positioning reference plate 310 and is fixedly connected by a hexagonal bolt assembly.

[0099] After the driven-side reference component 300 is assembled, it is hoisted into the pre-selected longitudinal positioning groove 130 using a reasonable hoisting method. The transverse limiting groove of the first positioning reference plate 340 matches the transverse positioning groove 120 on the support 100. The support 100 and the first positioning reference plate 340 of the driven-side reference component 300 are fixedly assembled using bolt and washer assemblies. The active-side positioning reference plate 210 and the driven-side positioning reference plate 310 are coplanar, and the relative dimensions of their first positioning groove 211 and second positioning groove 311 are fixed and conform to the dimensions in the drawings.

[0100] The driven side positioning reference plate 310 and the active side positioning reference plate 210 both have a first step positioning surface 212 and a second step positioning surface 213, and their functions are the same, so they will not be described in detail here.

[0101] Combination Figure 9 The installation process of the push rod support positioning component 400 is as follows: The operator, based on the design dimensions in the drawings and using the support base 100 as the measurement reference, measures and selects the position of the longitudinal positioning groove 130. Using the push rod bracket 410 as the assembly carrier, and utilizing the transverse and longitudinal limiting grooves of the second positioning reference plate 480 above the push rod bracket 410, the second positioning reference block 491 is fixed to the second positioning reference plate 480 using bolt and washer assemblies.

[0102] The height adjustment block 471 is optional; whether it needs to be installed depends on the design dimensions in the drawings. Alternatively, the height adjustment block 471 at the corresponding height can be installed to meet the positioning dimensions of the center plane of the push rod support 2 ear plate 2a.

[0103] Combination Figure 9 The push rod bracket 410 is provided with two symmetrically arranged pin positioning plates 460, which are fixed to the push rod bracket 410 by bolt washers. Figure 9 The transverse reference edge 413 and the longitudinal reference edge 414 in the middle can position the pin positioning plate 460.

[0104] Continue to combine Figure 9 As shown, there are multiple models of pin positioning plate 460 to choose from. The operator determines the corresponding first positioning pin hole 461 on the pin positioning plate 460 according to the design drawings. The position of the ear plate hole 2b of the push rod support 2 corresponding to each first positioning pin hole 461 is different.

[0105] The push rod bracket 410 has a slot 411 of a fixed width, which matches the thickness of the positioning plate 420. The push rod bracket 410 and the positioning plate 420 are connected by a rotating pin 440. One end of the rotating pin 440 has a step, and the other end is fixed by a cotter pin 450 to prevent movement. The pin positioning plate 460 has multiple models and can correspond to multiple first positioning pin holes 461.

[0106] After the push rod support positioning component 400 is assembled, the push rod support positioning component 400 is hoisted onto the support seat 100 using hoisting tools, so that the second positioning reference block 491 mates with the longitudinal positioning groove 130 and the transverse positioning groove 120 on the first surface 110 of the selected support seat 100 and is fixedly connected by bolt and washer assembly.

[0107] Figure 17 The dimensions and positioning references of the push rod support positioning component 400 are shown. The longitudinal positioning dimension B of the ear plate hole, the positioning dimension C of the opening center, and the transverse positioning dimension D of the ear plate hole are shown below. Figure 17 As shown. When determining the longitudinal positioning groove 130, the operator needs to know that the central axis of the first positioning pin hole 461 of the push rod support positioning component 400 coincides with the longitudinal reference center plane determined by the second longitudinal positioning reference block 491, and there is no deviation along the reference direction of the transverse positioning groove 120.

[0108] The positioning plate 420 matches the slot 411 and its plane inside the ear plate of the push rod support 2. Before positioning, the positioning plate 420 is rotated outward; when positioning is required, the positioning plate 420 is rotated inward to match the slot 411 of the push rod support 2. After the height of the push rod support 2 is positioned by the positioning plate 420, it is engaged with the ear plate hole 2b on the push rod support 2 by the first positioning pin 430. After determining the positioning welding position, the positioning can be welded. The push rod support positioning parts 400 are symmetrically arranged on both sides, and symmetrical positioning welding assembly is carried out according to the size requirements of the drawings.

[0109] Combination Figure 10 The installation process of the locking pin cylinder positioning component 500 is as follows: The operator selects the position of the longitudinal positioning groove 130 based on the dimensions designed in the drawings, using the support base 100 as the measurement reference. Using the locking pin positioning support 510 as the positioning reference, various models can be designed for selection based on the vertical distance between the second positioning pin hole 540 of the vertical plate 520 and the locking pin positioning support 510.

[0110] Figure 18 The positioning dimensions and positioning references of the locking pin positioning support 510 are shown. The lateral positioning dimension E and the pin center positioning dimension F are as follows: Figure 18 As shown. The center plane determined by the positioning reference planes on both sides of the vertical plate 520 coincides with the center plane of the transverse positioning groove 120. The vertical plate 520 has a second positioning pin hole 540, and the central axis of the second positioning pin hole 540 coincides with the center plane of the longitudinal positioning groove 130, as shown. Figure 18 As shown.

[0111] The bottom mounting reference of the locking pin positioning support 510 has a transverse limiting groove and a longitudinal limiting groove. The fourth positioning reference block 550 is fixed in the transverse and longitudinal limiting grooves using a bolt washer assembly. The locking pin positioning support 510 is fastened to the reference plane of the support base 100 using bolt washers and bolts. The fourth positioning reference block 550 is positioned in conjunction with the transverse positioning groove 120 and the longitudinal positioning groove 130 of the first surface 110 of the support base 100, respectively. Simultaneously, a second positioning pin 530 is used for positioning and connection with the locking pin cylinder support 3 during assembly. A schematic diagram of the locking pin cylinder positioning component 500 after it is integrally installed on the support base 100 is shown below. Figure 19 As shown.

[0112] Combination Figure 8 and Figure 11As shown, the installation process of the guide support positioning component 600 is as follows: The operator measures and selects the position of the longitudinal positioning groove 130 based on the dimensions designed in the drawings, using the support base 100 as the measurement reference. Using the guide seat positioning support 610 as the positioning reference, and considering the different vertical distances between the central axis of the central positioning hole 611 and the bottom plane of the guide seat positioning support 610, two models of the guide seat positioning support 610 are designed for selection and used in conjunction with the guide rod auxiliary positioning plate 630.

[0113] Furthermore, the outer end face of the guide seat positioning support 610 coincides with the outer plane of the bottom reference step. During assembly, this side end face fits against one side end face of the guide support 4 to determine the lateral positioning dimension of the guide support 4. The lateral positioning dimension G and the center positioning dimension H of the guide support are as follows: Figure 20 As shown.

[0114] The guide rod auxiliary positioning plate 630 is fixed to the mounting position of the support 100 by a hexagonal bolt and washer assembly. Its function is to define the mounting position of the guide support 4 and to visually determine the accuracy of the guide support 4's positioning. Figure 21 As shown.

[0115] The assembly process of the positioning welding equipment of the present invention is as follows: After the various assembly and positioning parts are ready for installation, the mounting bracket is attached as shown in the attached figure. Figure 6 Place the equipment as shown in the diagram. Use a crane and lifting equipment to lift the positioning welding equipment above the installation support. Remove the first guide rod 621 and the second guide rod 622 for later use. Remove the first positioning pin 430 for later use. Rotate the positioning plate 420 to open it to the outside for easy positioning. Remove the second positioning pin 530 for later use.

[0116] like Figure 22 As shown, the active side positioning reference plate 210 and the passive side positioning reference plate 310 are respectively fitted with the mounting steps of the support rings 1a and 1b at both ends of the balance beam 1 to complete the installation.

[0117] Combination Figures 23 to 25 As shown, the support ring mounting flanges of the balance beam 1 have different dimensions and forms, and the active side positioning reference plate 210 and the driven side positioning reference plate 310 can simultaneously meet the positioning requirements. After the alignment is in place, the assembly reference is established. The operator manually moves the push rod support 2, the locking pin cylinder support 3, and the guide support 4 to achieve the alignment and positioning.

[0118] Assembly and positioning step 1: Make the inner opening of the ear plate 2a of the push rod support 2 cooperate with the positioning plate 420, and then refer to the first positioning pin hole 461 on the pin positioning plate 460, and use the first positioning pin 430 to cooperate with it to determine the positioning size of the push rod support 2.

[0119] Assembly and positioning step 2: Make the set of ear plates 3a on the locking pin cylinder support 3, which coincides with the center, open inward and cooperate with the vertical plate 520 of the locking pin positioning support 510. Then, refer to the second positioning pin hole 540 on the locking pin positioning support 510, and use the second positioning pin shaft 530 to cooperate with it for positioning and assembly, and determine the positioning and welding dimensions of the locking pin cylinder support 3.

[0120] Assembly and Positioning Step 3: Align the end face of the guide seat positioning support 610 of the guide support 4 with the reference end face of the guide seat positioning support 610 to determine the lateral center distance positioning dimension between the guide support 4 and the balance beam 1. Then move the guide support 4 so that its fixed center hole 4a mates with the center positioning hole 611 of the guide seat positioning support 610, and insert the first guide rod 621 to fix its position. Next, move the guide support 4 so that its other center hole 4a mates with the corresponding waist-shaped positioning hole 612 of the guide seat positioning support 610, and insert the second guide rod 622 to assemble the guide support 4 in a horizontal position.

[0121] At this point, the relative positions of the balance beam 1, push rod support 2, locking pin cylinder support 3, and guide support 4 are completely determined, as follows: Figure 7 As shown, welding positioning operations can then be performed.

[0122] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Any variations and modifications can be made by those skilled in the art without departing from the spirit and scope of the invention. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the invention, fall within the protection scope defined by the claims of the present invention.
