Description

Technical Field

[0001] The utility model relates to the technical field of steel trusses, in particular to a quick-detachable adjustable steel box beam assembly frame. Background Art

[0002] Steel box girders are a common structural form for long-span bridges. They are generally connected by full welding of top plates, bottom plates, waist plates, transverse diaphragms, longitudinal diaphragms and stiffening ribs. The traditional assembly method is generally carried out outdoors, where the sections of the steel box girder are transported to the construction site, welded and assembled on site, and then set on the bridge piers.

[0003] During the on-site assembly process, a tire frame is usually used as a temporary auxiliary tool for assembling and positioning the steel box girder, providing precise positioning and support for the various components of the steel box girder to ensure that the various components can be accurately aligned during the assembly process, which plays an important role in ensuring construction quality and safety and improving construction speed. With the further development of bridge technology, for some bridge structures with variable shapes, it is generally necessary to set up multiple assembly tire frames of different heights and widths according to the shapes of different sections of the bridge as a means of adjusting the structural line shape and supporting the structural weight. Due to the poor versatility between different assembly tire frames, the tire frames need to be dismantled after use, which increases material loss and construction costs, is not convenient for construction personnel to operate, and affects construction efficiency.

[0038] On the basis of the above-mentioned embodiment, a sliding assembly 40 is arranged between each support assembly 30 and the top frame 11, and the sliding assembly 40 is arranged along the length direction of the first frame 10 or the second frame 20; the sliding assembly 40 allows the support assembly 30 to move along the length direction of the frame, and can drive the top connection block 30a to move quickly to the required support position according to actual needs, so as to adapt to steel box girder segments of different lengths, thereby reducing the time spent by construction personnel on positioning and adjusting the support assembly 30, thereby shortening the construction period.

[0041] On the basis of the above embodiment, the support rod 32 is a four-sided cube structure, and four diagonal support plates 34 are also arranged on the base 31. The two right-angled sides of the diagonal support plate 34 are respectively fixedly connected to the side of the support rod 32 and the side of the base 31 away from the slider 42; the support rod 32 with a four-sided cube structure provides a larger cross-section and a stronger bending resistance, thereby enhancing the structural strength of the support rod 32.

[0043] On the basis of the above embodiment, the locking portion 51 includes a mounting plate 511, a transfer rod 512, an elastic member 513 and a handle 514. One side of the mounting plate 511 is fixedly connected to one side of the first frame 10. The middle part of the transfer rod 512 is bent to form an L shape, and the bending part is rotatably connected to the other side of the mounting plate 511. The handle 514 is vertically fixedly arranged at the end of the transfer rod 512 away from the adjustment portion 52, and the two ends of the elastic member 513 are respectively fixedly connected to the mounting plate 511 and the end of the transfer rod 512 close to the handle 514. The other end of the transfer rod 512 is provided with a locking groove 512a and a guide surface 512b on the side facing the ground. The guide surface 512b is arranged opposite to the adjustment portion 52 and is inclined toward the locking groove 512a. The locking groove 512a is arranged toward the ground.

[0044] Through the guiding effect of the guide surface 512b, the adjustment part 52 can be guided into the locking groove 512a more smoothly, ensuring the accuracy of the assembly positioning; at the same time, through the limiting effect of the locking groove 512a on the adjustment part 52 and the limiting effect of the elastic member 513 on the rotation position of the transfer rod 512, the stability of the connection between the first frame 10 and the second frame 20 is ensured, and accidental disengagement is prevented, thereby improving construction safety; when it is necessary to contact the connection between the first frame 10 and the second frame 20, it is only necessary to pull the transfer rod 512 through the handle 514 to make the transfer rod 512 rotate relatively, and the locking groove 512a releases the limiting effect on the adjustment part 52 to complete the connection and separation process of the assembly unit is simplified.

[0045] The adjusting portion 52 includes an adapter plate 521, a limiting wheel 522, an adjusting block 523, a counterweight 524, an adjusting shaft 525 and a handle 526. The adapter plate 521 is bent to form a Z shape, and the limiting wheel 522 is rotatably set at one end of the adapter plate 521 and is clamped in the locking groove 512a; the adjusting block 523 is fixedly connected to the second frame 20, and an adjusting groove 523a is set on the side opposite to the other end of the adapter plate 521. The counterweight 524 is located between the adapter plate 521 and the adjusting block 523, and is fixedly set on the outer axial surface of the adjusting shaft 525. One end of the adjusting shaft 525 is fixedly connected to the adapter plate 521, and the other end extends into the adjusting groove 523a and is slidably connected to the adjusting block 523. The handle 526 is fixedly set on the side of the adapter plate 521 away from the counterweight 524.

[0046] When the positions of the first frame 10 and the second frame 20 are determined by the positioning assembly 50, the position of the first frame 10 and the gap value between the first frame 10 and the second frame 20 can be determined first, and the adapter plate 521 is pulled by the handle 526 to move the adjustment shaft 525 to the corresponding position in the adjustment groove 523a with fast adjustment. At this time, the second frame 20 can be pushed as a whole to move toward the side where the first frame 10 is located. When the limiting wheel 522 contacts the guide surface 512b, the relative force causes the adapter rod 512 to rotate a certain angle, so that the limiting wheel 522 can enter the adjustment groove 523a and automatically reset after entering, forming a limiting effect on the limiting wheel 522, thereby forming a precise guide to prevent relative offset between the first frame 10 and the second frame 20; the setting of the counterweight block 524 increases the stability of the adjustment part 52, prevents flipping or instability, and ensures safety in use.
