[0035] An embodiment of the present application provides a steel box girder assembly device for supporting and positioning steel plates to assemble a steel box girder bottom plate.

[0036] refer to Figures 1 to 4 In some embodiments, the steel box girder assembly device includes a first bracket 1, a plurality of support members 2, a first driving mechanism 3, a plurality of first adjustment components 4 and a first control machine 5. The plurality of support members 2 are arrayed on the upper surface of the first bracket 1, and the support members 2 are configured to have adjustable support heights. The first driving mechanism 3 is provided with a plurality of first driving ends, and the plurality of first driving ends are respectively connected to the plurality of support members 2, and the first driving ends are used to output driving forces to the corresponding support members 2 to adjust their support heights. The plurality of first adjustment components 4 are respectively provided at the plurality of first driving ends. The first control machine 5 is electrically connected to the plurality of first adjustment components 4, and the first control machine 5 is used to respectively control the plurality of first adjustment components 4 to adjust the driving forces of the plurality of driving ends so that the support heights of the plurality of support members 2 are adapted to the design curve of the bottom plate of the steel box girder.

[0037] Specifically, during use, the first control machine 5 can send instructions to each first adjustment component 4 to control each first adjustment component 4 to adjust the driving force of the corresponding first driving end, thereby adjusting the support height of the corresponding support member 2. Moreover, when the adjustment amount of each first adjustment component 4 is different, the driving force of each first driving end is different. The difference in driving force causes the support height (adjustment amount) of each support member 2 to be different, thereby enabling the multiple support members 2 to form support surfaces with different curves to adapt to the design curve of the steel box girder bottom plate.

[0038] According to the above solution, the steel box girder assembly device can form support surfaces with different curves by controlling the support heights of its multiple support members 2. This support surface can be used to support and position steel plates, thereby adapting to the assembly of steel box girder bottom plates with different design curves. Compared to the existing technology, this arrangement can achieve automated steel box girder assembly, making it faster and more accurate, and avoiding the waste of materials, labor, and time caused by adjusting the elevation of the steel frame.

[0039] In some embodiments, the first support 1 can be a grid-like support, and the first support 1 can be arranged overhead. For example, the first support 1 can be a grid-like support formed by welding transverse steel sections and longitudinal sections, with the bottom of the grid-like support suspended by support columns. This ensures ample working space at the bottom during assembly of the steel box girder, facilitating work for construction workers.

[0040] In some embodiments, the support member 2 is configured to be retractable, and the support member 2 can adjust its support height by retracting. In a specific configuration, the support member 2 can be a jack, such as a hydraulic jack, a mechanical jack, or a hydraulic screw jack. In this embodiment, the support member 2 is preferably a hydraulic jack.

[0041] In some embodiments, the first driving mechanism 3 may be a hydraulic system, that is, the first driving mechanism 3 is configured to output or recover hydraulic oil to extend or retract the support member 2. Figure 2 As shown, the first driving mechanism 3 may include a first oil tank 31, a first oil pump 32, a first oil inlet pipe 33 and a first oil outlet pipe 34. The first oil inlet pipe 33 and the first oil outlet pipe 34 are respectively connected between the support member 2 (hydraulic jack) and the first oil tank 31. The first oil inlet pipe 33 is used to deliver hydraulic oil into the support member 2 under the action of system pressure (first oil pump 32) to make it extend, and the first oil outlet pipe 34 is used to recover hydraulic oil to make the support member 2 contract.

[0042] refer to Figure 3 In some embodiments, the first adjustment assembly 4 includes a first electro-hydraulic flow valve 41, which is disposed on the first oil inlet pipe 33. In practice, the first electro-hydraulic flow valve 41 can be used to control the flow of hydraulic oil through the first electro-hydraulic flow valve 41, that is, the hydraulic oil inlet amount. It should be understood that different hydraulic oil inlet amounts will result in different extensions of the hydraulic jack. Therefore, by controlling the hydraulic oil inlet amount, the support height of the support member 2 can be adjusted.

[0043] refer to Figure 3 In some embodiments, the first adjustment component 4 further includes a second electro-hydraulic flow valve 42, and the second electro-hydraulic flow valve 42 is provided on the first oil outlet pipe 34. In specific use, the second electro-hydraulic flow valve 42 can be used to control the flow of hydraulic oil through the second electro-hydraulic flow valve 42, that is, the output of the hydraulic oil. It should be understood that when the hydraulic oil flows out of the cylinder of the hydraulic jack, the hydraulic jack can be contracted, and when the output of the hydraulic oil is equal to the input of the hydraulic oil, it can be determined that the hydraulic oil in the cylinder of the hydraulic jack has completely flowed out and the hydraulic jack has been reset. Therefore, by controlling the output of the hydraulic oil, the support height of the support member 2 can be adjusted, and it can also be ensured that the support member 2 is reset, so as to accurately control the extension and contraction of the support member 2 during subsequent operations.

[0044] In some embodiments, the first control machine 5 is specifically configured to determine the support height of each support member 2 based on the design curve parameters of the steel box girder bottom plate, and control the plurality of first adjustment assemblies 4 based on the support height of each support member 2. In specific use, the first control machine 5 can obtain the design curve parameters (such as beam axis length, beam width, curve elements, transverse slope, longitudinal slope, and pre-camber, etc.) set by the program or input by the operator, and determine the support height of each support member 2 based on the obtained design curve parameters, and then control the corresponding first electro-hydraulic flow valve 41 (i.e., the oil inlet amount of the corresponding first oil inlet pipe 33) according to the determined support height of each support member 2, so that each support member 2 reaches the required support height.

[0045] In some embodiments, the first control machine 5 is provided with a first information input terminal, which is used to input the design curve parameters of the steel box girder bottom plate. In specific settings, the first information input terminal can be a touch screen or a keyboard.

[0046] In some embodiments, the first control machine 5 controls the plurality of first adjustment components 4 by means of group control. Specifically, group control software can be installed on the first control machine 5, and the first control machine 5 can simultaneously calculate the support height of each support member 2 through the group control software, and can also simultaneously control the support height of each support member 2 through the group control software, such as Figure 4 shown.

[0047] The steel box girder assembly device provided in the embodiment of the present application is also used to extrude steel plates to bend and deform them to form steel box girder webs or steel box girder head plates.

[0048] refer to Figure 1 、 Figures 5 to 7 In some embodiments, the steel box girder assembly device includes a second bracket 6, multiple extrusion members 7, a second driving mechanism 8, multiple second adjustment components 9 and a second control machine 10; the multiple extrusion members 7 are respectively located on opposite sides of the first bracket 1 and are arranged on the second bracket 6, and the extrusion members 7 are configured to be able to move in the horizontal direction; the second driving mechanism 8 is provided with multiple second driving ends, and the multiple second driving ends are respectively connected to the multiple extrusion members 7, and the second driving ends are used to output driving force to the corresponding extrusion members 7 to make them move in the horizontal direction for extrusion; the multiple second adjustment components 9 are respectively provided at the multiple second driving ends; the second control machine 10 is electrically connected to the multiple second adjustment components 9, and the second control machine 10 is used to respectively control the multiple second adjustment components 9 to adjust the driving force of the multiple second driving ends so that the movement stroke of the multiple extrusion members 7 adapts to the design curve of the steel box girder web or the steel box girder head plate.

[0049] Specifically, during use, the second control machine 10 can send instructions to each second adjustment component 9 to control each second adjustment component 9 to adjust the driving force of the corresponding second driving end, thereby adjusting the movement stroke of the corresponding extrusion member 7. Moreover, when the adjustment amount of each second adjustment component 9 is different, the driving force of each second driving end is different. The difference in driving force causes the movement stroke of each extrusion member 7 to be different, so that the extrusion members 7 on both sides of the steel plate can squeeze the steel plate to bend and deform according to the designed curve to form the steel box girder web or steel box girder head plate.

[0050] According to the above solution, the steel box girder assembly device can control the stroke of its multiple extrusion members 7 to squeeze the steel plate so that it bends and deforms according to the designed curve, thereby forming a steel box girder web or steel box girder header plate on the steel box girder bottom plate. This arrangement makes the steel box girder assembly device suitable for assembling steel box girder webs or steel box girder header plates of different shapes. Moreover, during the assembly process, the steel box girder web or steel box girder header plate can be directly fixed to the steel box girder bottom plate after being bent and formed, which is beneficial to improving the efficiency of steel box girder assembly.

[0051] In some embodiments, there are multiple second brackets 6 , and the multiple second brackets 6 are respectively arranged on opposite sides of the first bracket 1 , and the multiple extrusion members 7 are respectively arranged on the inner sides of the multiple second brackets 6 .

[0052] refer to Figure 1 In some embodiments, some of the multiple extrusions 7 are located on opposite sides of the first bracket 1 in the first direction, and the remaining extrusions 7 are located on opposite sides of the first bracket 1 in the second direction. In specific use, when the steel plate is arranged along the first direction of the first bracket 1, the extrusions 7 located on both sides of the first bracket 1 in the second direction can be used to extrude the steel plate so that the steel plate is bent and deformed to form the web of the steel box girder. When the steel plate is arranged along the second direction of the first bracket 1, the extrusions 7 located on both sides of the first bracket 1 in the first direction can be used to extrude the steel plate so that the steel plate is bent and deformed to form the head plate of the steel box girder. In this embodiment, the first direction is the width direction of the first bracket 1, and the second direction is the length direction of the first bracket 1.

[0053] In some embodiments, the extrusion member 7 is configured to be retractable, and the extrusion member 7 adjusts its travel by retracting. In a specific configuration, the extrusion member 7 can be a jack, such as a hydraulic jack, a mechanical jack, or a hydraulic screw jack. In this embodiment, the extrusion member 7 is preferably a hydraulic jack.

[0054] In some embodiments, the second driving mechanism 8 may be a hydraulic system, that is, the second driving mechanism 8 is configured to output or recover hydraulic oil to extend or retract the extrusion member 7. Figure 5 As shown, the second drive mechanism 8 may include a second oil tank 81, a second oil pump 82, a second oil inlet pipe 83 and a second oil outlet pipe 84. The second oil inlet pipe 83 and the second oil outlet pipe 84 are respectively connected between the extrusion 7 (hydraulic jack) and the second oil tank 81. The second oil inlet pipe 83 is used to send hydraulic oil into the extrusion 7 under the action of the system pressure (second oil pump 82) to make it expand, and the second oil outlet pipe 84 is used to recover the hydraulic oil to make the extrusion 7 contract. However, the embodiment of the present application does not impose any limitation on this. In other embodiments, the steel box girder assembly device can also control the expansion and contraction of the extrusion 7 through the first drive mechanism 3.

[0055] refer to Figure 6 In some embodiments, the second adjustment assembly 9 includes a third electro-hydraulic flow valve 91, which is disposed on the second oil inlet pipe 83. In practice, the third electro-hydraulic flow valve 91 can be used to control the flow of hydraulic oil through the third electro-hydraulic flow valve 91, that is, the hydraulic oil inlet amount. It should be understood that different hydraulic oil inlet amounts will result in different extensions of the hydraulic jack. Therefore, by controlling the hydraulic oil inlet amount, the operating stroke of the extrusion member 7 can be adjusted.

[0056] refer to Figure 6 In some embodiments, the second regulating assembly 9 further includes a fourth electro-hydraulic flow valve 92, which is disposed on the second oil outlet pipe 84. In specific use, the fourth electro-hydraulic flow valve 92 can be used to control the flow of hydraulic oil through the fourth electro-hydraulic flow valve 92, that is, the output of the hydraulic oil. It should be understood that when the hydraulic oil flows out of the oil cylinder of the hydraulic jack, the hydraulic jack can be contracted, and when the output of the hydraulic oil is equal to the input of the hydraulic oil, it can be determined that the hydraulic oil in the oil cylinder of the hydraulic jack has completely flowed out and the hydraulic jack has been reset. Therefore, by controlling the output of the hydraulic oil, the action stroke of the extrusion member 7 can be adjusted, and it can also be ensured that the extrusion member 7 is reset, so as to accurately control the expansion and contraction of the extrusion member 7 during subsequent operations.

[0057] In some embodiments, the second control machine 10 is specifically used to determine the action stroke of each extrusion 7 based on the design curve parameters of the steel box girder web or the steel box girder head plate, and control multiple second adjustment components 9 according to the action stroke of each extrusion 7. During specific use, the second control machine 10 can obtain the design curve parameters set by the program or input by the operator (such as beam axis length, beam width, curve elements, transverse slope, longitudinal slope and pre-arch, etc.), and determine the action stroke of each extrusion 7 based on the obtained design curve parameters, and then control the corresponding third electro-hydraulic flow valve 91 (that is, the oil inlet amount of the corresponding second oil inlet pipe 83) according to the determined action stroke of each extrusion 7, so that each extrusion 7 can reach the required action stroke. However, the embodiments of the present application do not impose any restrictions on this. In other embodiments, the steel box girder assembly device can also control the second adjustment component 9 through the first control machine 5.

[0058] In some embodiments, the second control machine 10 controls the plurality of second adjustment components 9 by means of group control. Specifically, group control software can be installed on the second control machine 10, and the second control machine 10 can simultaneously calculate the motion strokes of the various extrusion components 7 by means of the group control software, and can also simultaneously control the motion strokes of the various extrusion components 7 by means of the group control software, such as Figure 4 shown.
