Description

Technical Field

[0001] The utility model belongs to the technical field of steel box girder processing, and particularly relates to an anti-deformation jig for bridge plate units. Background Technique

[0002] In the field of bridge engineering, as an important structural form, steel box girders are widely used in the construction of long-span bridges. The processing and manufacturing of steel box girders is a complex and delicate process. Among them, the manufacturing and splicing of plate units (including top plate unit parts, bottom plate unit parts, web plate unit parts, and diaphragm unit parts) are one of the key links. During the welding process of these plate units, due to the influence of welding heat input, welding deformations such as angular deformation, wavy deformation, and torsional deformation will inevitably occur. If these deformations are not controlled, they will seriously affect the overall dimensional accuracy and load-bearing capacity of the steel box girder.

[0003] In order to effectively reduce welding deformations and improve the processing quality of plate units, the industry generally uses anti-deformation jigs for the production of plate units. The anti-deformation jig gives the plate unit a deformation amount opposite to the welding deformation direction in advance to offset the deformation generated during the welding process, so as to achieve the purpose of controlling the final shape. When the existing anti-deformation jigs press the plate units, most of them use pressure-type devices. However, the pressure rods of the pressure-type devices generally have a small cross-section, which is prone to deformation and inability to be tightly pressed, or the pressing plate device is too large and it is necessary to weld stiffeners on the upper part of the plate unit, resulting in an increase in cost.

[0004] In view of the above problems, it is particularly important to develop a light and efficient pressing plate device for the anti-deformation jig of bridge plate units that can stably provide a pressing force and does not require additional increase in the structural complexity of the plate unit. The device should have sufficient stiffness and strength to maintain a stable pressing state during the welding process. At the same time, the convenience of operation and cost-effectiveness should also be considered to meet the requirements of modern bridge engineering for high-quality and high-efficiency processing and manufacturing. Content of the Utility Model

[0005] Aiming at the problems existing in the prior art, the utility model provides an anti-deformation jig for bridge plate units, which can stably provide a pressing force and does not require additional increase in the structural complexity of the plate unit.

[0006] In order to solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] According to the first aspect of the present utility model, a bridge plate unit anti-deformation jig is provided, which includes two crescent plate bases arranged opposite to and parallel to each other. On the upper end surface of each crescent plate base, there is a crescent plate. Between the two crescent plate bases, there are two sliding seats that can reciprocally slide along the length direction of the crescent plate bases. On the upper end surface of each sliding seat, there is a telescopic driving device that can telescopically move up and down in the vertical direction. The telescopic end of each telescopic driving device is fixedly sleeved with a first horizontal rectangular plate. At the bottom of one end of the two first horizontal rectangular plates facing each other, there is a pressure strip, and the pressure strip is used to contact the upper end surface of the bridge plate unit.

[0008] In a possible implementation manner of the first aspect, both of the two crescent plate bases are in an I shape. Each sliding seat includes a moving wheel group and a support fixed on the moving wheel group. The moving wheel group and the support are slidably arranged between the upper and lower flange plates of the two crescent plate bases, and the fixed end of the telescopic driving device is fixed at the center position of the upper end surface of the support.

[0009] In a possible implementation manner of the first aspect, at the bottom of the end of the first horizontal rectangular plate away from the pressure strip, there is a vertical plate, and a reinforcing rib plate is connected between the vertical plate and the corresponding pressure strip.

[0010] In a possible implementation manner of the first aspect, the telescopic end of each telescopic driving device is fixedly sleeved with a second horizontal rectangular plate, and the second horizontal rectangular plate is fixedly connected to the upper end surface of the corresponding first horizontal rectangular plate.

[0011] In a possible implementation manner of the first aspect, the lower end surface of the pressure strip is in an arc structure.

[0012] In a possible implementation manner of the first aspect, the two ends of the two crescent plate bases are connected by sliding seat limit plates.

[0013] In a possible implementation manner of the first aspect, the middle positions of the two crescent plate bases are connected by sliding seat limit plates.

[0014] In a possible implementation manner of the first aspect, the bottom of the crescent plate is fixedly connected with a mounting plate, and the mounting plate and the corresponding crescent plate base are detachably connected by bolt members.

[0015] In a possible implementation manner of the first aspect, between the two sides of the crescent plate and the corresponding mounting plate, there are several stiffening plates.

[0016] According to the second aspect of the present utility model, there is provided a method for using a bridge plate unit anti-deformation jig. Place the bridge plate unit on the crescent plates of multiple bridge plate unit anti-deformation jigs, control the two sliding seats to approach both sides of the bridge plate unit, so that the pressing strip is located above the bridge plate unit, control the telescopic ends of the two telescopic driving devices to synchronously retract downward, drive the corresponding first horizontal moment plates to move downward, thereby making the pressing strip contact the upper end face of the bridge plate unit and pressing the bridge plate unit downward.

[0017] Compared with the prior art, the present utility model has at least the following beneficial effects:

[0018] The present utility model provides a bridge plate unit anti-deformation jig. When in use, place the bridge plate unit on the crescent plates of multiple bridge plate unit anti-deformation jigs, control the two sliding seats to approach both sides of the bridge plate unit, so that the pressing strip is located above the bridge plate unit. Then control the telescopic ends of the two telescopic driving devices to synchronously retract downward, drive the corresponding first horizontal moment plates to move downward, thereby making the pressing strip contact the upper end face of the bridge plate unit and pressing the bridge plate unit downward. It can be seen that the present utility model adopts two slidable sliding seats, which can adapt to the anti-deformation production of bridge plate units with different widths. More importantly, during the anti-deformation process, since the pressing strip is used to contact the upper end face of the bridge plate unit, the stress area at the edge of the bridge plate unit is effectively increased, solving the problems existing in the prior art that the cross-section of the pressing rod of the pressure-type device of the anti-deformation jig is small, prone to deformation and unable to be tightly pressed, and at the same time avoiding the welding problem of additional stiffeners on the upper part of the plate unit due to the too large pressing plate device. Therefore, the present utility model can stably provide a pressing force and does not require additional increase in the structural complexity of the plate unit.

Detailed implementation manners

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0031] Combined with Figure 1 and Figure 2As shown in the figure, the embodiment of the present utility model provides an anti-deformation jig for bridge plate units, aiming to achieve a light, efficient and stable pressing plate function through optimized structural design to meet the anti-deformation requirements during the manufacturing process of bridge plate units. The anti-deformation jig for bridge plate units includes two crescent plate bases 1 arranged opposite to and parallel with each other. On the upper end surface of each crescent plate base 1, there is a crescent plate 2. Between the two crescent plate bases 1, there are two sliding seats 3 that can reciprocally slide along the length direction of the crescent plate base 1. On the upper end surface of each sliding seat 3, there is a telescopic driving device 4 that can telescopically move up and down in the vertical direction. The telescopic end of each telescopic driving device 4 is fixedly sleeved with a first horizontal rectangular plate 5. At the bottom of one end of the two first horizontal rectangular plates 5 facing each other, there is a pressing strip 6, and the pressing strip 6 is used to contact the upper end surface of the bridge plate unit.

[0032] Specifically, two crescent plate bases 1 arranged opposite to and parallel with each other are used as the basic supports. On the upper end surface of each crescent plate base 1, there is a crescent plate 2, and the crescent plate 2 is used to directly support the bridge plate unit. Between the two crescent plate bases 1, there are two sliding seats 3, and the sliding seats 3 can reciprocally slide along the length direction of the crescent plate base 1. This design can flexibly adapt to bridge plate units of different widths or lengths, improving versatility. On the upper end surface of each sliding seat 3, there is a telescopic driving device 4 that can telescopically move up and down in the vertical direction. The telescopic driving device 4 can be an electric push rod, a hydraulic cylinder or a pneumatic cylinder, etc., to achieve precise control. The telescopic end of each telescopic driving device 4 is fixedly sleeved with a first horizontal rectangular plate 5. The first horizontal rectangular plate 5 serves as the support structure for the pressing strip 6, and its design needs to ensure sufficient stiffness and strength to withstand the force generated during the downward pressing process. At the bottom of one end of the two first horizontal rectangular plates 5 facing each other, there is a pressing strip 6, and the pressing strip 6 needs to ensure a good pressing effect when contacting the upper end surface of the bridge plate unit and will not damage the plate surface.

[0033] Combined Figure 8 As shown in the figure, the usage method of the present utility model is as follows:

[0034] First, place the bridge plate unit to be processed on the crescent plates 2 of multiple anti-deformation jigs for bridge plate units to ensure the stability and accurate position of the bridge plate unit.

[0035] Then, by controlling the two sliding seats 3 to slide along the length direction of the crescent plate base 1, make the sliding seats 3 approach both sides of the bridge plate unit to ensure that the pressing strip 6 can be located above the bridge plate unit.

[0036] Then, start the two telescopic driving devices 4 and control their telescopic ends to synchronously retract downward, driving the corresponding first horizontal rectangular plates 5 to move downward. As the first horizontal rectangular plates 5 descend, the pressing strip 6 gradually contacts the upper end surface of the bridge plate unit and applies a downward pressure to press the bridge plate unit downward to achieve the anti-deformation effect.

[0037] Finally, after the caulking strip 6 contacts the bridge plate unit and a certain pressure is applied, fine-tuning is carried out as required to ensure that the bridge plate unit is in an ideal reverse deformation state. After the welding of the bridge plate unit is completed, the telescopic drive device 4 moves in the reverse direction, the caulking strip 6 disengages from the bridge plate unit, and the pressing plate device is retracted to the end of the reverse deformation jig by moving the sliding seat 3 outward, and the production of the bridge plate unit is completed.

[0038] In one realizable manner, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 , both of the two crescent plate bases 1 are in the shape of an I-beam. Each sliding seat 3 includes a moving wheel set 300 and a support 301 fixed on the moving wheel set 300. The moving wheel set 300 and the support 301 are slidably arranged between the upper and lower flange plates of the two crescent plate bases 1, and the fixed end of the telescopic drive device 4 is fixed at the center position of the upper end face of the support 301.

[0039] Specifically, both of the two crescent plate bases 1 are designed in an I-beam structure. This design not only enhances the overall strength and stability of the base, but also provides sufficient space for the sliding seat 3 and its components to slide therein. The I-beam base includes an upper flange plate, a lower flange plate, and a web connecting the two. The upper flange plate is used to support the crescent plate 2, and the lower flange plate serves as part of the moving track of the sliding seat 3. Each sliding seat 3 is composed of a moving wheel set 300 and a support 301 fixed on the moving wheel set 300. The moving wheel set 300 includes a number of rollers or bearings, which are designed to be able to roll between the upper and lower flange plates of the I-beam base, so as to realize the reciprocating sliding of the sliding seat 3 along the length direction of the crescent plate base 1. The support 301, as part of the sliding seat 3, is also located between the upper and lower flange plates, and cooperates to realize the vertical limit of the sliding seat 3. The fixed end of the telescopic drive device 4 is fixed at the center position of the upper end face of the support 301 by bolts, welding or other fastening methods. This layout ensures that the telescopic drive device 4 can maintain stability during the telescopic process and can effectively transmit the driving force to the first horizontal moment plate 5.

[0040] When the anti-deformation jig for bridge plate units is needed, first place the bridge plate unit on the crescent plate 2 and adjust the position of the sliding seat 3 according to the width of the bridge plate unit. By sliding the moving wheel set 300 on the I-shaped base, the sliding seat 3 can be easily moved close to both sides of the bridge plate unit. Then, start the telescopic driving device 4 and control its telescopic end to retract downward, so as to drive the first horizontal moment plate 5 and the pressure strip 6 to move downward until the pressure strip 6 is in close contact with the upper end surface of the bridge plate unit and applies sufficient pressure. The anti-deformation jig for bridge plate units of the present utility model is not only compact in structure and simple in operation, but also has high stability and reliability, and can meet the anti-deformation requirements during the manufacturing process of bridge plate units.

[0041] Exemplarily, as Figure 3 shown, the moving wheel set 300 is composed of 2 steel bars with a length of 460 mm and a diameter of 40 mm, which are respectively sleeved into 4 bearings with an outer diameter of 80 mm and an inner diameter of 40 mm, and then welded together by 2 round steel bars with a length of 140 mm and a diameter of 40 mm. As Figure 4 shown, the support 301 is composed of 1 steel plate with a thickness of 30 mm, a width of 250 mm and a length of 370 welded to 2 steel plates with a thickness of 30 mm, a width of 100 mm and a length of 340 mm.

[0042] In an implementable way, combining Figure 2 and Figure 5 shown, at the bottom of the end of the first horizontal moment plate 5 far from the pressure strip 6, there is a vertical plate 7, and a reinforcing rib plate 8 is connected between the vertical plate 7 and the corresponding pressure strip 6.

[0043] Specifically, at the bottom of the end of the first horizontal moment plate 5 far from the pressure strip 6, there is a vertical plate 7. The vertical plate 7 is perpendicular to the first horizontal moment plate 5, and a reinforcing rib plate 8 is connected between the vertical plate 7 and the corresponding pressure strip 6. The reinforcing rib plate 8 is a structural strengthening member, and its shape and quantity can be designed according to actual needs to significantly improve the connection strength between the first horizontal moment plate 5 and the pressure strip 6 and the stiffness of the overall structure without significantly increasing the overall weight. The reinforcing rib plate 8 can be fixed to the vertical plate 7 and the pressure strip 6 by welding, bolt connection or other reliable connection methods. The setting of the vertical plate 7 and the reinforcing rib plate 8 effectively enhances the stiffness of the first horizontal moment plate 5 in the vertical direction, making it not easily bend and deform when bearing the downward pressure, thus ensuring the close contact and uniform pressing between the pressure strip 6 and the upper end surface of the bridge plate unit. Through the combined action of the vertical plate 7 and the reinforcing rib plate 8, the overall stability of the first horizontal moment plate 5 is significantly improved, which helps to maintain stability during the anti-deformation process and reduce errors caused by vibration or external force interference.

[0044] It can be seen that the setting of the vertical plate 7 and the reinforcing rib plate 8 in this embodiment can improve the stiffness and stability of the jig and provide more reliable and efficient anti-deformation support for the manufacturing of bridge plate units.

[0045] Exemplarily, as Figure 5 shown, the first horizontal rectangular plate 5 is a steel plate with a thickness of 30 mm, a width of 250 mm, and a length of 550. A hole with a diameter of 105 mm is formed in the middle of the first horizontal rectangular plate 5. The vertical plate 7 is a steel plate with a thickness of 10 mm, a width of 120 mm, and a length of 300 mm. There are two reinforcing rib plates 8 in total, both of which are steel plates with a thickness of 10 mm, a width of 120 mm, and a length of 500 mm. The pressure strip 6 is a steel bar with a thickness of 30 mm, a width of 30 mm, and a length of 400 mm. The lower part of the pressure strip 6 is processed with a rounded corner.

[0046] Preferably, in combination with Figure 2 and Figure 6 shown, a second horizontal rectangular plate 9 is fixedly sleeved at the telescopic end of each telescopic driving device 4, and the second horizontal rectangular plate 9 is fixedly connected to the upper end surface of the corresponding first horizontal rectangular plate 5.

[0047] That is to say, the telescopic end of each telescopic driving device 4 is no longer directly fixedly sleeved on the first horizontal rectangular plate 5, but first fixedly sleeved with a second horizontal rectangular plate 9. The second horizontal rectangular plate 9 is fixed to the telescopic end of the telescopic driving device 4 in a factory prefabricated manner, ensuring the reliability of the structure. The second horizontal rectangular plate 9 is a component for transition and enhancing the connection strength. The second horizontal rectangular plate 9 is fixedly connected to the upper end surface of the corresponding first horizontal rectangular plate 5 by bolt connection, welding or other reliable connection methods. This connection method ensures the close fit and stable connection between the second horizontal rectangular plate 9 and the first horizontal rectangular plate 5. At the same time, due to the introduction of the second horizontal rectangular plate 9, the telescopic force of the telescopic driving device 4 can be more evenly transmitted to the first horizontal rectangular plate 5, reducing the risk of damage caused by local stress concentration.

[0048] In summary, the second horizontal rectangular plate 9, as a transition component between the telescopic driving device 4 and the first horizontal rectangular plate 5, enhances the connection strength between the two, helping to maintain the stability and reliability of the pressing plate during the anti-deformation process. Through the transition effect of the second horizontal rectangular plate 9, the telescopic force of the telescopic driving device 4 can be more smoothly and evenly transmitted to the first horizontal rectangular plate 5, and then transmitted to the pressure strip 6 and the bridge plate unit, achieving a better anti-deformation effect.

[0049] Exemplarily, as Figure 6 shown, the second horizontal rectangular plate 9 is a steel plate with a thickness of 30 mm, a width of 220 mm, and a length of 300 mm. The telescopic driving device 4 is an oil cylinder with a two-way stroke of 200 mm, and the two are welded together.

[0050] In an implementable manner, in combination with Figure 2 and Figure 5 shown, the lower end surface of the pressure strip 6 is in an arc structure. This design enables the pressure strip 6 to have a smooth transition when contacting the upper end surface of the bridge plate unit, avoiding damaging the bridge plate unit.

[0051] In one implementable manner, in combination with Figure 1 and Figure 7 As shown, both ends of the two crescent plate bases 1 are connected by the sliding seat limiting plates 10. That is to say, both ends of the two crescent plate bases 1 in the length direction are respectively connected by the sliding seat limiting plates 10. The sliding seat limiting plates 10 are fixed to the ends of the crescent plate base 1 by bolt connection, welding or other reliable connection methods. Their main function is to limit the sliding range of the sliding seat 3 on the crescent plate base 1 and prevent the sliding seat 3 from detaching from the base during movement. The setting of the sliding seat limiting plates 10 enhances the structural stability of the entire jig, especially when under greater pressure or external force, it can prevent the crescent plate base 1 from deforming or displacing. By restricting the sliding range of the sliding seat 3, the sliding seat limiting plates 10 ensure that the sliding seat 3 moves within a predetermined track, thereby ensuring the accuracy and controllability of the anti-deformation process.

[0052] Exemplarily, as Figure 7 shown, the crescent plate base 1 is a hot-rolled steel I-beam with a length of 4500 mm and a cross-section of HW200*200*8*12. The center distance between the two crescent plate bases 1 is 500 mm. The sliding seat limiting plate 10 is a hot-rolled steel I-beam with a length of 500 mm and a cross-section of HN200*100*5.5*8.

[0053] Preferably, the middle positions of the two crescent plate bases 1 are also connected by the sliding seat limiting plates 10. The setting of the middle sliding seat limiting plates 10 enables the crescent plate base 1 to be more evenly supported and fixed in the length direction, thereby enhancing the overall rigidity of the entire jig and reducing the errors caused by structural deformation during the anti-deformation process. By simultaneously setting the sliding seat limiting plates 10 in the middle and at both ends, a more stable frame structure is formed, making the anti-deformation jig for the bridge plate unit more stable when under pressure or external force and less likely to tip over or displace. In addition, it can also prevent the two sliding seats 3 from colliding.

[0054] In combination with Figure 7As shown, a mounting plate 11 is fixedly connected to the bottom of the crescent plate 2. The mounting plate 11 is detachably connected to the corresponding crescent plate base 1 by bolt members. The function of the mounting plate 11 is to provide a stable mounting foundation for the crescent plate 2 and achieve a detachable connection with the crescent plate base 1 through bolt members. Specifically, mounting holes are pre-set on the mounting plate 11, and these mounting holes are matched with the corresponding mounting holes on the crescent plate base 1. By passing bolt members (such as bolts, nuts, etc.) through these mounting holes, the mounting plate 11 and the crescent plate base 1 are tightly connected together. This connection method is not only firm and reliable but also convenient for disassembly and replacement. When the crescent plate 2 or the crescent plate base 1 is damaged or needs to be repaired, the crescent plate 2 can be easily removed from the base by disassembling the bolt members, which is convenient for maintenance and replacement. More importantly, the detachable connection is also beneficial for adjusting the height of the crescent plate 2 to meet different reverse deformation requirements.

[0055] As Figure 7 As shown, a number of stiffening plates 12 are provided between the two sides of the crescent plate 2 and the corresponding mounting plates 11. The stiffening plates 12 are plate-like structures with a certain thickness and rigidity, and their quantity, position, and size are determined according to the specific shapes, sizes, and force-bearing conditions of the crescent plate 2 and the mounting plates 11. These stiffening plates 12 are fixed between the two sides of the crescent plate 2 and the mounting plates 11 by welding connections to form a stable triangular support structure. The setting of the stiffening plates 12 enhances the connection strength between the crescent plate 2 and the mounting plates 11, making the connection between the two more firm and reliable and capable of withstanding greater pressure and external forces. During the reverse deformation process, the crescent plate 2 may be subjected to greater stress and deformation. The setting of the stiffening plates 12 helps to disperse these stresses over a larger area, reduce local stress concentration, and extend the service life of the structure. By strengthening the connection between the crescent plate 2 and the mounting plates 11, the overall performance of the entire bridge plate unit reverse deformation jig is improved, and it can better meet the reverse deformation requirements during the production process.

[0056] The utility model is simple to operate. There is no need for welding positioning. Just slide the pressing plate device to the required position on the reverse deformation jig steel beam and apply pressure through the oil cylinder. The operator does not need a high technical level. The fittings used in this device are all common fittings. If there are any problems, they can be replaced at any time. According to different reverse deformation jigs, the device can be finely adjusted and put into use, with strong applicability.
