Description

Technical Field

[0001] This utility model belongs to the field of steel bridge manufacturing technology, specifically relating to a retractable steel component transfer platform. Background Technology

[0002] With the continuous improvement of urbanization, urban steel bridges have gradually become a city's calling card. Cable-stayed bridges, due to their magnificent shapes, beautiful lines, and unique structural systems, perfectly meet the needs of both practical and aesthetic value, and are gradually becoming iconic urban structures. The pylons of reinforced concrete cable-stayed bridges typically consist of a steel frame reinforced with steel sections to bear the main loads and a concrete tower body to enhance structural strength. During the fabrication of the pylon's steel frame, the steel tower column is divided into multiple separately manufactured steel components along its height. These components are characterized by complex structures, large cross-sectional variations, large spatial inclination angles, and weak inherent rigidity. Due to these structural characteristics, these components require multiple supports and have gradually changing cross-sections during fabrication and transportation, making fabrication and transportation extremely difficult.

[0003] Traditional steel component transfer platforms are usually fixed-section platforms that cannot be changed. However, for complex steel frame structures like these, traditional transfer platforms can cause significant deformation to the steel components themselves. At the same time, they cannot be flexibly adjusted according to the size and shape of the variable-section steel components. This results in the need to frequently change or adjust the platform when transferring steel components of different sizes, increasing the complexity and time cost of the transfer, and posing significant safety hazards.

An electric telescopic rod 16 is rotatably connected to the surface of the support frame 1, and the piston rod of the electric telescopic rod 16 is rotatably connected to the bottom side of the adjustable bracket 4. The distance between the support frame 1 and the sliding frame 3 can be adjusted by moving the sliding frame 3 within the inner wall of the first limiting cylinder 2. The support angle of the first support rod 5 can be changed by adjusting the support angle of the first pallet 6. At the same time, the support height and angle of the adjustable bracket 4 can be adjusted by the electric telescopic rod 16 to support steel components of different sizes and improve the stability and safety of the steel components during transportation.

[0026] Specifically, a first telescopic rod 7 is slidably connected inside the first support rod 5, and a first sliding block 9 is rotatably connected to one end of the outer side of the first telescopic rod 7. A first guide groove 8 is provided on the surface of the longitudinal rod of the sliding frame 3 for guiding the first sliding block 9.

[0027] In a specific embodiment of this utility model, by sliding the first telescopic rod 7 on the inner wall of the first support rod 5, and at the same time driving the first sliding block 9 to slide on the inner wall of the first guide groove 8, the first support rod 5 and the first support plate 6 are better supported, and the support angle of the first support rod 5 can be easily adjusted.

[0028] Specifically, the surface of the adjusting cylinder 11 is provided with a plurality of first limiting holes 13, and the mounting cylinder 10 is provided with a first fixing bolt 14 adapted to the first limiting holes 13.

[0029] In a specific embodiment of this utility model, by moving the adjusting cylinder 11 along the inner wall of the mounting cylinder 10, and then assembling the first fixing bolt 14 into the corresponding first limiting hole 13, the adjusting cylinder 11 is limited, thereby increasing the support effect of the second support plate 12.

[0030] Specifically, two second support rods 18 are rotatably connected to the support frame 1, and two second telescopic rods 17 are rotatably connected to the upper end of the adjustable bracket 4, with the two second telescopic rods 17 slidably connected to the inner walls of the two second support rods 18 respectively.

[0031] In a specific embodiment of this utility model, when the adjustable bracket 4 moves, it will drive the second telescopic rod 17 to move on the inner wall of the second support rod 18, thereby increasing the stability of the adjustable bracket 4 after adjustment by the electric telescopic rod 16.

Then, the second fixing bolt 22 is assembled to the surface of the corresponding second limiting hole 21, which also increases the stability between the first limiting cylinder 2 and the sliding frame 3.

[0034] Specifically, guide cylinders 24 are horizontally installed on both sides of the support frame 1, and slide rods 23 are horizontally installed on the longitudinal rods of the sliding frame 3, with the slide rods 23 slidably connected inside the guide cylinders 24.

[0035] In a specific embodiment of this utility model, the sliding rod 23 is driven by the sliding frame 3 to slide on the inner wall of the guide cylinder 24, which can further increase the support effect between the support frame 1 and the sliding frame 3.

[0036] Working principle: The sliding frame 3 moves within the inner wall of the first limiting cylinder 2, adjusting the distance between the support frame 1 and the sliding frame 3. The first telescopic rod 7 is slidably connected to the inner wall of the first support rod 5, and the first telescopic rod 7 drives the first sliding block 9 to slide within the inner wall of the first guide groove 8, thus better supporting the first support rod 5 and the first pallet 6, and facilitating the adjustment of the support angle of the first support rod 5. By adjusting the support angle of the first support rod 5, the support angle of the first pallet 6 can be changed. By moving the adjusting cylinder 11 within the inner wall of the mounting cylinder 10, and then assembling the first fixing bolt 14 into the corresponding first limiting hole 13, the adjusting cylinder 11 is limited, thereby increasing the support effect of the second pallet 12.
