Description

Technical Field

[0001] The disclosed embodiments relate to the technical field of crescent plate manufacturing, and in particular to a crescent plate device with adjustable profile for welding steel box girder plate units and a method for using the same. Background Art

[0002] Steel box girders are a common structural form for long-span steel bridges. Steel box girder manufacturing typically utilizes a "plate-plate unit-segment" manufacturing process to achieve precise control of the girder's manufacturing accuracy. As the smallest unit component in steel box girder manufacturing, the plate unit requires welding U-shaped or plate-shaped stiffeners onto long steel plates. However, dense stiffeners can cause the steel plates to bend and deform during welding, severely impacting the plate unit's manufacturing accuracy. To ensure that the welded plate unit's manufacturing quality meets relevant standards, it is typically thermally straightened after welding. This not only increases the time and cost of plate unit manufacturing, but repeated thermal straightening can also degrade the steel plate's performance, impacting the overall load-bearing capacity of the steel bridge deck. Therefore, during the manufacture of existing steel box girder plate units, a special mold is used to pre-apply a certain amount of pressure in the opposite direction of the welding deformation, causing the plate unit to undergo a certain amount of reverse deformation. The two long sides of the plate unit are then hydraulically compressed, and the plate unit stiffener welds are then welded. After the welding of the steel box girder plate unit is completed, the clamping device is gradually loosened to release the preload pressure. Through this reverse deformation, the purpose of reducing the plate unit after welding or eliminating the need for correction is achieved.

[0003] In related technologies, the anti-deformation mold structure is relatively simple. Regardless of the specifications of the plate unit, the same set of anti-deformation crescent plates with a fixed preset camber are used. According to engineering practice, setting the same anti-deformation amount on the anti-deformation mold cannot accurately achieve the welding anti-deformation of plate units of different specifications and different numbers of stiffening ribs. This results in a mismatch between the pre-designed anti-deformation amount and the actual required post-weld deformation amount, making the plate unit welding anti-deformation mold ineffective. How to optimize and adjust the anti-deformation mold to achieve arbitrary adjustment of the pre-weld anti-deformation amount of plate units of various specifications, so that the plate units can achieve the desired effect without or with little correction of flatness, has become a technical problem that urgently needs to be solved.

[0004] Therefore, it is necessary to improve one or more problems existing in the above-mentioned related technical solutions.

[0005] It should be noted that this section is intended to provide background or context for the technical solutions of the present disclosure stated in the claims. The description herein is not admitted to be prior art by virtue of being included in this section. Summary of the Invention

[0006] The purpose of the embodiments of the present disclosure is to provide a steel box girder plate unit welding profile adjustable crescent plate device and a method of use, thereby at least to a certain extent overcoming one or more problems caused by the limitations and defects of the relevant technology.

[0007] According to a first aspect of an embodiment of the present disclosure, there is provided a crescent plate device with adjustable profile for welding a steel box girder plate unit, comprising:

[0008] The crescent plate comprises two first crescent plate units; wherein the crescent plate is used to provide an anti-deformation force in the opposite direction of the welding deformation to the plate unit before welding, so as to meet a preset anti-deformation amount of the plate unit before welding;

[0009] A horizontal moving component is arranged at the bottom of the two sections of the first crescent plate units, and is used to move the two sections of the first crescent plate units in the horizontal direction. When the two sections of the first crescent plate units are relatively far away from each other, a plurality of second crescent plate units are arranged between the two sections of the first crescent plate units that are relatively far away from each other to adapt to the plate units of different specifications.

[0010] In one embodiment of the present disclosure, a first scale mark is provided on the vertical line where the highest point of each second crescent plate unit is located, and a second scale mark is provided on the vertical line where the lowest point of each second crescent plate unit is located.

[0011] In one embodiment of the present disclosure, a pushing mechanism is further included. The pushing mechanism is arranged at the bottom of the horizontal moving assembly and is used to adjust the height of the two sections of the first crescent plate units and all the second crescent plate units.

[0012] In one embodiment of the present disclosure, the horizontal movement component includes:

[0014] A slide groove is provided at the bottom of the crescent plate, and each of the rolling elements is slidably provided in the slide groove, so that each section of the first crescent plate unit moves horizontally to adapt to the plate units of different specifications.

[0015] In one embodiment of the present disclosure, the relatively distant ends of the two sections of the first crescent plate units are respectively provided with insertion holes, and a plurality of pairs of positioning holes are evenly spaced on the slide groove. When each section of the first crescent plate unit is moved to a corresponding position in the slide groove, a fixing piece is inserted into any pair of the positioning holes and the insertion hole to fix the first crescent plate unit.

[0016] According to a second aspect of an embodiment of the present disclosure, a method for using a steel box girder plate unit welding profile-adjustable crescent plate device is provided, comprising:

[0017] Several groups of crescent plates are evenly arranged at the bottom of the plate unit at a preset interval to provide a counter-deformation force opposite to the welding deformation direction to the plate unit before welding, so as to meet the preset counter-deformation amount of the plate unit before welding; wherein each group of crescent plates located at both ends is fixed to the plate unit by a clamp on the tire frame, and the remaining groups of crescent plates are used to support the plate unit;

[0018] By means of a horizontal moving assembly, the two sections of the first crescent plate units in each group of the crescent plates are adjusted to move in the horizontal direction. When the two sections of the first crescent plate units in each group of the crescent plates are relatively far apart, a plurality of second crescent plate units are arranged between the two sections of the first crescent plate units that are relatively far apart to adapt to the plate units of different specifications.

[0019] In one embodiment of the present disclosure, when a group of the crescent plates is in the middle position of the bottom of the plate unit, the preset anti-deformation amount is reflected by the difference between the first scale scale and the second scale scale of the second crescent plate unit located in the middle position in the group of the crescent plates.

[0020] In one embodiment of the present disclosure, the horizontal movement assembly is used to adjust the horizontal movement of the two first crescent plate units in each group of crescent plates. When the two first crescent plate units in each group of crescent plates are relatively separated, a plurality of second crescent plate units are provided between the two relatively separated first crescent plate units to accommodate plate units of different specifications. The following steps are then included:

[0021] The height of each group of crescent plates is adjusted by a pushing mechanism located at the bottom thereof to adapt to the preset reverse deformation amount of the plate unit.

[0022] In one embodiment of the present disclosure, the horizontal movement assembly is used to adjust the horizontal movement of the two first crescent plate units in each group of crescent plates. When the two first crescent plate units in each group of crescent plates are relatively separated, a plurality of second crescent plate units are provided between the two relatively separated first crescent plate units to accommodate plate units of different specifications. The following further comprises:

[0023] The horizontal moving assembly includes rolling elements and sliding grooves. The rolling elements are evenly spaced and arranged at the bottom of each section of the first crescent plate unit, and the sliding groove is arranged at the bottom of each group of the crescent plates.

[0024] When each section of the first crescent plate unit moves to the corresponding position in the slide groove by relying on the rolling member at its bottom, the first crescent plate unit is fixed by inserting a fixing member into a pair of positioning holes on any of the slide grooves and the insertion hole on the first crescent plate unit.

[0025] The technical solutions provided by the embodiments of the present disclosure may have the following beneficial effects:

[0026] In the disclosed embodiments, the aforementioned device and method divides the crescent into two first crescent units, which are then horizontally moved by a horizontally movable assembly. When the first crescent units are relatively far apart, a plurality of second crescent units are positioned between the two first crescent units to accommodate plate units of varying sizes. This method, by segmenting a continuous crescent and adding second crescent units after segmentation, meets the preset anti-deformation requirements for plate units of varying sizes.

[0037] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0038] In addition, the accompanying drawings are merely schematic illustrations of embodiments of the present disclosure and are not necessarily drawn to scale. Like reference numerals in the figures represent like or similar parts, and thus repeated descriptions thereof will be omitted. Some of the blocks shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically separate entities.

[0039] like Figure 1 As shown, the crescent plate used in the traditional anti-deformation mold is a full-length structure with a preset anti-deformation camber of a fixed value. The anti-deformation amount is adjusted only by the two long side clamping devices. For plate units with different widths and different numbers of stiffeners, it is impossible to match the preset anti-deformation amount with the actual requirements. Moreover, the welding deformation in the longitudinal direction of the steel box girder plate unit cannot be controlled by adjusting the preset anti-deformation amount of the anti-deformation mold. Therefore, a device with an adjustable crescent plate for the welding mold of the steel box girder plate unit is designed. By adjusting the crescent plate height and length direction, the preset anti-deformation amount of various types of steel box girder plate units can be accurately set.

[0040] In this exemplary embodiment, a steel box girder plate unit welding profile adjustable crescent plate device is first provided. Figure 2 and Figure 3 As shown in , the device may include: a crescent plate 100 and a horizontal moving component.

[0041] The crescent plate 100 includes two first crescent plate units 101. The crescent plate 100 is used to provide an anti-deformation force in the opposite direction of the welding deformation to the plate unit 600 before welding, so as to meet a preset anti-deformation amount of the plate unit 600 before welding.

[0042] A horizontal moving component is arranged at the bottom of the two sections of the first crescent plate units 101, and is used to move the two sections of the first crescent plate units 101 in the horizontal direction. When the two sections of the first crescent plate units 101 are relatively far away from each other, a plurality of second crescent plate units 200 are arranged between the two sections of the first crescent plate units 101 that are relatively far away from each other to adapt to the plate units 600 of different specifications.

[0043] The above-described device and method divides the crescent plate 100 into two first crescent plate units 101, and uses a horizontal movement assembly to achieve horizontal movement of the two first crescent plate sections 101. When the first crescent plate units 101 are relatively far apart, a plurality of second crescent plate units 200 are positioned between the two first crescent plate units 101 to accommodate plate units 600 of varying specifications. This method, by segmenting the continuous crescent plate 100 and adding second crescent plate units 200 after the segmentation, meets the predetermined anti-deformation requirements of plate units 600 of varying specifications.

[0044] Below, we will refer to Figures 2 to 5 The various parts of the above-mentioned steel box girder plate unit welding profile adjustable crescent plate device in this exemplary embodiment are described in more detail.

[0045] In one embodiment, Figure 2 、 Figure 3 and Figure 4 As shown, the device includes a crescent plate 100 and a horizontal movement assembly. The crescent plate 100 includes two first crescent plate units 101, that is, the crescent plate 100 is divided into two sections of the full-length structure, forming two first crescent plate units 101. The horizontal movement assembly disposed at the bottom of the first crescent plate 101 allows the two first crescent plate units 101 to move horizontally, that is, the two first crescent plate units 101 can be moved relatively away from each other or closer together. When the two first crescent plate units 101 are relatively far apart, a plurality of second crescent plate units 200 can be added between the two relatively far-flung first crescent plate units 101 to increase the width of the crescent plate 100 and accommodate plate units 600 of different sizes. The specific number of second crescent plate units 200 is set according to actual conditions and is not limited by this disclosure.

[0046] It should be noted that the added second crescent plate unit 200 and the curvature of the two sections of the first crescent plate unit 101 form a complete curvature, which is used to provide an anti-deformation force in the opposite direction of the welding deformation to the plate unit 600 before welding to match the preset anti-deformation amount of the plate unit 600.

[0047] It should be noted that the plate units 600 come in various sizes and specifications, and therefore require different pre-set deformation amounts before welding. The present disclosure divides the crescent plate 100 into two sections, and uses a horizontally movable assembly to adjust the distance between the two first crescent plate units 101, thereby adjusting the overall width of the segmented crescent plate 100, to meet the pre-set anti-deformation requirements of the plate units 600 of different specifications.

[0048] In one embodiment, a first scale mark 201 is provided on the vertical line where the highest point of each second crescent plate unit 200 is located, and a second scale mark 202 is provided on the vertical line where the lowest point of each second crescent plate unit 200 is located.

[0049] Specifically, such as Figure 3 As shown, to accurately reflect the preset deflection amount of the plate unit 600, a first scale mark 201 is provided on the vertical line at the highest point of each second crescent plate unit 200, and a second scale mark 202 is provided on the vertical line at the lowest point. Furthermore, when the crescent plate 100 is at the middle position of the bottom of the plate unit 600, the preset deflection amount is reflected by the difference between the first scale mark 201 and the second scale mark 202 of the second crescent plate unit 200 at the middle position.

[0050] It should be noted that the present disclosure, by providing the first scale mark 201 and the second scale mark 202 on the second crescent plate 100, can achieve precise adjustment of the preset reverse pressure, thereby matching the preset camber of the plate unit 600 with the actual value of the preset reverse deformation amount. This allows the plate unit 600 to achieve the preset reverse deformation amount after welding without correction or with minimal correction of flatness. The preset camber is the preset reverse deformation amount.

[0051] In one embodiment, a pushing mechanism 500 is further included. The pushing mechanism 500 is disposed at the bottom of the horizontal moving assembly and is used to adjust the heights of the two sections of the first crescent plate units 101 and all the second crescent plate units 200 .

[0052] It should be noted that if Figure 5 and Figure 6 As shown, to adjust the height of the crescent plate 100, the present disclosure incorporates a push mechanism 500 at the bottom of the horizontally movable assembly. This push mechanism 500 adjusts the overall height of the two first crescent plate units 101 and all second crescent plate units 200, ensuring that they match the predetermined deflection values ​​of the different plate units 600. The push mechanism 500 can be a hydraulic jack, and its details are readily understood with reference to existing technologies and are not further elaborated herein.

[0053] In one embodiment, the horizontal movement component comprises:

[0054] Rolling members 300, each of which is evenly spaced and arranged at the bottom of each section of the first crescent plate unit 101;

[0055] The slide groove 400 is provided at the bottom of the crescent plate 100 , and each of the rolling elements 300 is slidably provided in the slide groove 400 , so that each section of the first crescent plate unit 101 moves horizontally to adapt to the plate units 600 of different specifications.

[0056] Specifically, such as Figure 3 、 Figure 4 and Figure 5 As shown, to better adjust the horizontal movement of the first crescent plate unit 101, the horizontal movement assembly of the present disclosure includes rolling elements 300 and a slide 400. The rolling elements 300 are evenly spaced at the bottom of each first crescent plate unit 101, and the slide 400 is provided at the bottom of the crescent plate 100. The first crescent plate unit 101 relies on the rolling elements 300 at its bottom to move horizontally within the slide 400, that is, to move left and right within the slide 400, thereby better adjusting the overall width of the crescent plate 100 to accommodate different specifications of the plate units 600. The rolling elements 300 are rollers.

[0057] It should be noted that a rolling element 300 is also provided at the bottom of the second crescent plate unit 200 between the two first crescent plate units 101, and the rolling element 300 can also move within the slide groove 400. The rolling element 300 is provided at the bottom of the second crescent plate unit 200 for another purpose: to ensure that it is coplanar with the bottoms of the two first crescent plate units 600, thereby better providing a counter-deformation force to the plate unit 600 in the opposite direction of the welding deformation before welding.

[0058] In one embodiment, the relatively distant ends of the two sections of the first crescent plate unit 101 are respectively provided with insertion holes, and a plurality of pairs of positioning holes are evenly spaced on the slide groove 400. When each section of the first crescent plate unit 101 moves to the corresponding position in the slide groove 400, a fixing piece is inserted into any pair of the positioning holes and the insertion hole to fix the first crescent plate unit 101.

[0059] Specifically, after the rolling member 300 at the bottom of the first crescent unit 101 slides to its desired position within the chute 400, the plate unit 600 positioned above the first crescent unit 101 can squeeze the first crescent unit 101. Since the rolling member 300 slides within the chute 400, it could potentially slide further after reaching its desired position, causing the first crescent unit 101 to move. Therefore, to prevent the rolling member 300 at the bottom of the first crescent unit 101 from continuing to move after sliding to its desired position within the chute 400, several pairs of positioning holes are evenly spaced in the chute 400, and insertion holes are provided at the relatively distant ends of the two first crescent units 101. After each first crescent unit 101 moves to its desired position within the chute 400, a fixing member is inserted into any pair of positioning holes and insertion holes to secure the first crescent unit 101. The fixing member is a latch.

[0060] It should be noted that the positioning holes can be arranged in the chute 400 at a preset distance of 50 to 100 mm. Furthermore, the preset distance can be 50 mm, 60 mm, 80 mm or 100 mm, etc. The specific distance can be selected according to actual conditions and is not limited in this disclosure.

[0061] This example embodiment also provides a method for using a steel box girder plate unit welding profile adjustable crescent plate device. Figure 7 As shown in , the method includes: steps S801 to S802.

[0062] Among them, step S801: several groups of crescent plates 100 are evenly arranged at the bottom of the plate unit 600 according to a preset spacing, so as to provide a counter-deformation force in the opposite direction of the welding deformation to the plate unit 600 before welding, so as to meet the preset counter-deformation amount of the plate unit 600 before welding; wherein, each group of the crescent plates 100 located at both ends is fixed to the plate unit 600 by a clamp on the tire frame, and the remaining groups of the crescent plates 100 are used to support the plate unit 600.

[0063] Step S802: By means of a horizontal moving assembly, the two sections of the first crescent plate units 101 in each group of the crescent plates 100 are adjusted to move in the horizontal direction. When the two sections of the first crescent plate units 101 in each group of the crescent plates 101 are relatively far apart, a plurality of second crescent plate units 200 are arranged between the two sections of the first crescent plate units 101 that are relatively far apart to accommodate the plate units 600 of different specifications.

[0064] Reference below Figures 2 to 8 The various parts of the method for using the device for welding the steel box girder plate unit 600 with an adjustable profile crescent plate 100 in this exemplary embodiment will be described in more detail.

[0065] In one embodiment, before welding the plate unit 600, several sets of crescent plates 100 are first arranged on the tire frame 700 at a preset spacing, and then the plate unit 600 is placed on the sets of crescent plates 100. The two sets of crescent plates 100 at the two ends are secured to the plate unit 600 via clamps on the tire frame. The clamps can be clips or buckles, and their specific structure can be understood with reference to the prior art and is not limited in this disclosure. The remaining sets of crescent plates 100 located between the two ends are then in close contact with the plate unit 600, primarily to support the plate unit 600. The preset spacing is 1.5m.

[0066] It should be noted that because the crescent plate 100 comprises two first crescent plate units 101, the crescent plate 100 is designed in sections to accommodate plate units 600 of varying sizes. A horizontally movable assembly at the bottom of each set of crescent plate 100 allows the two first crescent plate units 101 to move away from or toward each other. Furthermore, to accommodate plate units 600 of varying sizes, a second crescent plate unit 200 can be added between the two first crescent plate units 101 in each set of crescent plates 101 when the two first crescent plate units 101 are relatively far apart, thereby increasing the overall width of each set of crescent plates 100.

[0067] It should also be noted that in order to better adapt to plate units 600 of different specifications, the number of second crescent plate units 200 added in each group of crescent plates 100 can be the same or different, and can be set according to actual conditions. This disclosure does not impose any restrictions on this.

[0068] In one embodiment, when a group of the crescent plates 100 is located in the middle position of the bottom of the plate unit 600, the preset anti-deformation amount is reflected by the difference between the first scale and the second scale of the second crescent plate unit 200 located in the middle position in the group of the crescent plates 100.

[0069] It should be noted that in order to more accurately reflect the preset anti-deformation amount of the plate unit 600, a first scale mark 201 is set on the vertical line where the highest point of each second crescent plate unit 200 in each group of crescent plates 100 is located, and a second scale mark 202 is set on the vertical line where the lowest point is located. Then, when a group of crescent plates 100 is in the middle position of the bottom of the plate unit 600, the preset anti-deformation amount is specifically reflected by the difference between the first scale mark 201 and the second scale mark 202 of the second crescent plate unit 200 located in the middle position.

[0070] By accurately reflecting the preset reverse deformation amount through the precise numerical difference, the preset reverse pressure can be accurately adjusted, so that the preset curvature of the plate unit 600 is matched with the actual value of the preset reverse deformation amount, so that the plate unit 600 can reach the preset reverse deformation amount after welding without correction or with less correction of flatness.

[0071] In one embodiment, the horizontal movement assembly is used to adjust the horizontal movement of the two first crescent plate units 101 in each group of crescent plates 100. When the two first crescent plate units 101 in each group of crescent plates 100 are relatively separated, a plurality of second crescent plate units 200 are provided between the two relatively separated first crescent plate units 101 to accommodate plate units 600 of different specifications. The following steps are then included:

[0072] The height of each group of crescent plates 100 is adjusted by a pushing mechanism 500 located at the bottom thereof to adapt to a preset reverse deformation amount of the plate unit 600 .

[0073] Specifically, after adjusting the overall width of each group of crescent plates 100, if the curvature of all crescent plates 100 does not match the curvature of the plate unit 600, the height of any group of crescent plates 100 can be adjusted by the pushing mechanism 500 to match the curvature of all crescent plates 100 with the curvature of the plate unit 600, thereby adjusting the preset anti-deformation amount of the plate unit 600. During the adjustment, the curvature of all crescent plates 100 is adapted to the preset anti-deformation amount of the plate unit 600 after adjustment.

[0074] In one embodiment, the horizontal movement assembly is used to adjust the horizontal movement of the two first crescent plate units 101 in each group of the crescent plates 100. When the two first crescent plate units 101 in each group of the crescent plates 100 are relatively separated, a plurality of second crescent plate units 200 are provided between the two relatively separated first crescent plate units 101 to accommodate plate units 600 of different specifications. The following further comprises:

[0075] The horizontal moving assembly includes rolling elements 300 and sliding grooves 400. The rolling elements 300 are evenly spaced and arranged at the bottom of each section of the first crescent plate unit 101, and the sliding grooves 400 are arranged at the bottom of each group of the crescent plates 100.

[0076] When each section of the first crescent plate unit 101 moves to the corresponding position in the slide groove 400 by relying on the rolling member 300 at its bottom, the first crescent plate unit 101 is fixed by inserting a fixing member into a pair of positioning holes on any of the slide grooves 400 and the insertion hole on the first crescent plate unit 101.

[0077] Specifically, to prevent the rolling element 300 at the bottom of the first crescent plate unit 101 from sliding further after reaching a desired position within the chute 400, several pairs of positioning holes are evenly spaced apart on the chute 400, and insertion holes are provided at the relatively distant ends of the two first crescent plate units 101. After each first crescent plate unit 101 has moved to a desired position within the chute 400, a fixing member is inserted into any pair of positioning holes and insertion holes to secure the first crescent plate unit 101.
