Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tire frames, in particular to an arc-shaped template support frame. Background Art
[0002] With the continuous development of urban transportation networks, overpasses in urban bridges are becoming more and more common. In order to minimize the impact on traffic, overpasses are increasingly using steel structures, and as a result, the vertical curves of steel box girders are increasingly arc-shaped. During processing, steel box girders are generally transported in sections to the site for assembly and welding after processing in the processing plant. Therefore, processing plants near the steel box girder installation site are generally selected. However, the sites of steel box girder processing plants are difficult to meet the overall construction requirements of a unit of steel box girders. One reason is that the site length is not long enough. Even if the site is long enough, there are still problems such as a long overall processing time for the steel box girder and low construction efficiency. The site will choose to process the steel box girder in sections.
[0003] Authorization publication number "CN217816025U" records "a CNC adjustable hydraulic tire frame, including a base plate and rollers installed around the bottom of the base plate through wheel seats, a hydraulic support column is fixedly installed inside the base plate and on the inner side of the four rollers, the output end of the hydraulic support column is fixedly installed with a floor surface, lifting components are provided on both sides of the base plate surface, and a tire frame group is provided between the two lifting components. When the hydraulic support column is in the retracted state, the rollers can be used to flexibly push the entire equipment to move, which is convenient and dexterous. When in use, the hydraulic support column is started until the rollers are off the ground to ensure the stability of the entire frame. When in use, the height of the tire frame frame can be changed by lifting the motor, lifting screw and lifting plate. At the same time, the splint can be pushed to rotate by the hydraulic push rod, so that the two splints can be brought closer to each other, thereby achieving the purpose of changing the clamping force. Its convenient adjustment effect greatly improves the practicality of the entire equipment."
[0004] The above patent can use rollers to flexibly push the entire equipment to move, which is convenient and flexible, and easy to adjust, greatly improving the practicality of the entire equipment. However, the currently used tire frame is a 1:1 disposable tire membrane frame, and in many cases the length of the processing site cannot meet the 1:1 processing of steel box girders, and can only be processed in sections. The accuracy of the segmented processing is difficult to ensure that it meets the specification requirements. The joint seam error of the segmented processed steel box girder is large, and it is difficult to control its width to meet the specification requirements. Moreover, the longitudinal slope of the bridge is not a fixed value. The tire frames of the steel box girders are all disposable, which will consume a lot of labor and material costs. Utility Model Content
[0005] The utility model provides an arc-shaped formwork support frame, which can cyclically process continuous steel box girders of unlimited length by assembling base plates and waiting for the use of partitioned base plates, eliminating the problem that the steel box girders can only be processed in sections due to the limitation of the processing site, and the need for pre-assembly and difficult control of assembly seam errors. It has the characteristics of high construction efficiency, wide application scenarios, low construction cost, and high construction precision. Through the use of the support mechanism, the longitudinal slope of the frame can be quickly and accurately adjusted by numerical control, which improves the construction efficiency and reduces the repeated manual adjustments during the construction of the steel box girder due to inconsistent longitudinal slopes of the bridge. It can not only well ensure the processing precision and processing quality of the steel box girder, but also greatly improve the construction efficiency and reduce the construction cost. It is suitable for the construction of steel box girders with various slopes, and the effect is particularly obvious in the construction of vertical curves and steel box girders with larger single-joint lengths.

[0024] Assemble substrate 1;
[0025] Waiting for substrate 2, waiting for substrate 2 to be fixedly connected to one end of assembly substrate 1;
[0026] A hoisting mechanism is provided on the waiting substrate 2 and is extended on the assembly substrate 1 for hoisting the device; and
[0027] The supporting mechanism is provided with multiple groups, and the multiple groups of supporting mechanisms are respectively installed on the assembly base plate 1 and the waiting base plate 2. Each group of supporting mechanisms includes multiple longitudinal slope CNC adjusting devices 7, manual height adjustment device beams 6 and multiple dome manual height adjustment devices 5.

[0028] In this embodiment: the assembly substrate 1 and the waiting substrate 2 are connected together, so that the device as a whole forms two areas, there are multiple assembly areas on the assembly substrate 1, and the waiting substrate 2 is a waiting area. The two cooperate with each other, and the overall processing effect can be achieved during segmented processing, which can effectively avoid the segmented processing error problem and solve the problem that the processing plant site does not have a long processing object. The horizontal slope adopts a dome manual height adjustment device 5, and the longitudinal slope adjustment adopts a longitudinal slope CNC adjustment device 7, which can quickly adjust various different longitudinal slopes of the bridge. The combination of the two can ensure that the device meets different requirements. The waiting area and the assembly area can be set according to the frequently used length. The waiting area can be set at 10-30m, and the assembly area can be set at 30-90m.
[0029] Specifically, the hoisting mechanism includes a movable guide component and a gantry crane 3. The movable guide component is arranged on the waiting base plate 2, and the movable guide component is extended on the assembly base plate 1. The gantry crane 3 is installed on the movable guide component.
[0030] In this embodiment: the gantry crane 3 is an application of the existing technology, which will not be described in detail here. The supporting mechanism and the supported device are hoisted and used by the gantry crane 3.
[0031] Specifically, the movable guide components are two guide rails 8 , which are respectively fixedly connected to the top ends of the assembly substrate 1 near the edges, and both guide rails 8 are extended onto the waiting substrate 2 .
[0032] In this embodiment, the two guide rails 8 limit the moving path of the gantry crane 3 to ensure stable movement.
[0033] Specifically, a steel box beam 4 is placed on top of the multiple dome manual height adjustment devices 5 .
[0034] In this embodiment, the steel box girder 4 is also called a steel plate box girder, which is a commonly used structural form for long-span bridges and is generally used on bridges with larger spans. It is called a steel box girder 4 because of its box-like appearance.
[0035] During use, first process multiple sections on the assembly base plate 1 as a whole, and after the processing is completed, move the adjacent sections that have not been processed to the waiting base plate 2. The waiting base plate 2 and the assembly base plate 1 are the construction joints of the two sections of steel box beam 4. After adjusting the longitudinal slope, assemble the unfinished steel box beam 4 under the joint constraints of the completed steel box beam 4 sections and the tire frame of the assembly base plate 1, so that the construction joints of the steel box beam 4 are all in-situ docked, avoiding the situation where the width of the docking joints of the steel box beam 4 are different during installation. Move the supporting mechanism to the assembly base plate 1 through the gantry crane 3. After completion, ensure that it is fixed. At the same time, move the steel box beam 4 to the supporting mechanism. During use, adjust the data of the supporting mechanism according to the steel box beam 4, the dome manual height adjustment device 5 ensures the overall height adjustment of the transverse slope, and the longitudinal slope CNC adjustment device 7 can quickly adjust various different longitudinal slopes of the bridge. The combination of the two can ensure that the device meets the size requirements of different positions of the steel box beam 4, so that the supporting mechanism fits the steel box beam 4.

The wiring diagram of the power element and the provision of power supply are common knowledge in the field. Moreover, the present invention is mainly used to protect mechanical devices. Therefore, the control method and wiring arrangement are not explained in detail in the present invention.
