Description

Technical Field

[0001] This utility model relates to the field of bridge construction equipment technology, and in particular to a construction platform for highway bridge engineering. Background Technology

[0002] In the construction and maintenance of highway bridges, the construction work on the sides and underside of the bridge is a crucial step. For example, when installing crash barriers, repairing bridge underside defects, or applying anti-corrosion coatings, construction workers need to reach this specific location on the side and underside of the bridge to carry out their work. Due to the special location of the bridge sides and underside, ordinary ground construction equipment cannot directly reach and carry out operations. Therefore, it is usually necessary to set up a special construction platform on the side of the bridge to provide a stable and safe working space for construction workers, ensuring the smooth progress of the construction process.

[0003] In the prior art, such as Chinese utility model patent with patent number CN204023415U, a construction device for bridge crash barriers is disclosed. The support in the construction device can move on the bridge surface, thereby allowing the working platform on the support to be adjusted in position along the length of the bridge surface. Construction personnel can conveniently adjust the entire construction device to different construction sections of the bridge, which to a certain extent meets the needs of construction scenarios on the side of the bridge.

[0004] However, in actual highway bridge side and underpass construction, different working height requirements arise. For example, when repairing cracks at different heights at the bridge underpass, or installing and maintaining ancillary facilities at different heights on the bridge side, the work platform needs to be able to adjust its working height so that construction workers can work in a suitable posture and distance. However, the work platforms in the aforementioned existing technologies have obvious drawbacks; their working height is fixed and cannot be flexibly adjusted according to actual construction needs. Utility Model Content

[0014] The inner side of the vertical beam has multiple hanging holes that are spaced apart vertically.

[0015] The hydraulic cylinder drives the hook portion of the hook to engage with the hanging hole, thereby achieving a locking connection between the padlock mechanism and the upright beam.

[0016] As a further optional solution, the guiding mechanism includes multiple sets of first guide wheels, which are rotatably disposed on the side of the hanger, and the multiple sets of first guide wheels are distributed vertically.

[0017] The side of the upright beam with the hanging hole is defined as the first side surface, and the first guide wheel slides against the first side surface.

[0018] As a further alternative, the width of the first guide wheel is greater than the width of the hanging hole.

[0042] refer to Figures 1 to 6This utility model discloses a construction platform for highway bridge engineering, including a base frame 1, a suspended platform 2, a guiding mechanism 3, and a padlock mechanism 4. The base frame 1 includes two vertically arranged upright beams 11, and an electric hoist 12 located between the two upright beams 11 is provided on the base frame 1. The suspended platform 2 is located between the two upright beams 11, and the suspended platform 2 includes a working platform 21 and a hanging frame 22 provided on the working platform 21. The hanging frame 22 is connected to the electric hoist 12. The guiding mechanism 3 is provided on the hanging frame 22, and the guiding mechanism slides vertically with the upright beams 11. The padlock mechanism 4 is provided on the hanging frame 22 and is used for locking with the upright beams 11.

[0043] Specifically, by installing an electric hoist 12 on the base frame 1, the lifting and lowering of the suspended platform 2 can be precisely controlled, enabling flexible adjustment of the working height of the work platform 21. This effectively solves the problem of inconvenience caused by the inability to adjust the working height of the work platform 21 in the prior art, and meets the diverse needs of different construction tasks for working height. At the same time, the guide mechanism 3 allows the hanging frame 22 and the upright beam 11 to slide vertically, providing stable guidance for the lifting and lowering of the suspended platform 2 and ensuring the smoothness of the lifting process. In addition, the padlock mechanism 4 can lock and connect with the upright beam 11 when the suspended platform 2 reaches a suitable height, enhancing the stability of the suspended platform 2, preventing it from accidentally shaking or falling, and also reducing the load on the electric hoist 12, providing a safer and more reliable working environment for construction personnel.

[0044] In some embodiments, such as Figure 3 and Figure 4 As shown, there are two padlock mechanisms 4, which are respectively located on both sides of the top of the hanger 22. Each padlock mechanism 4 includes a mounting base 41, a hook 42, and a hydraulic cylinder 43. The mounting base 41 is fixedly mounted on the bracket. The first end 42a of the hook 42 forms a hook portion 421, and the second end 42b of the hook 42 is connected to the hydraulic cylinder 43. A hinge portion 42c is formed between the first end 42a and the second end 42b of the hook 42, and the hinge portion 42c is hinged to the mounting base 41. The inner side of the upright beam 11 has a plurality of hanging holes 111 that are distributed vertically at intervals. The hydraulic cylinder 43 drives the hook portion 421 of the hook 42 to engage with the hanging hole 111, thereby realizing the locking connection between the padlock mechanism 4 and the upright beam 11.

[0045] Specifically, see Figure 4The piston rod on the hydraulic cylinder 43 is connected to the second end 42b of the hook 42. When the hydraulic cylinder 43 retracts, the second end 42b of the hook 42 can drive the hook 42 to rotate around the hinge 42c, so that the hook part 421 on the hook 42 disengages from the hanging hole 111. At this time, the position of the basket 2 can be adjusted by the electric hoist 12. Conversely, after the position of the basket 2 is adjusted, the piston rod of the hydraulic cylinder 43 extends, so that the hook 42 rotates and the hook part 421 of the hook 42 engages with the hanging hole 111. This allows the basket 2 to be stably set on the base frame 1, ensuring the stable setting of the basket 2 and reducing the load on the electric hoist 12 when it is not working.

[0046] Two padlock mechanisms 4 are respectively installed on both sides of the hanger 22, which further ensures the stable installation of the hanger 22.

[0047] In some embodiments, such as Figure 3 As shown, the guiding mechanism 3 includes multiple sets of first guide wheels 31, which are rotatably disposed on the side of the hanger 22. The multiple sets of first guide wheels 31 are distributed vertically. The side of the upright beam 11 with the hanging hole 111 is defined as the first side surface 11a, and the first guide wheel 31 slides against the first side surface 11a.

[0048] Thus, during the lifting and lowering of the suspended platform 2, the two sides of the suspension frame 22 can slide and engage with the inner side (first side 11a) of the vertical beam 11 through the first guide wheel 31, thereby improving the stability of the suspended platform 2 during lifting and lowering.

[0049] In addition, to prevent the first guide wheel 31 from being embedded in the hanging hole 111, such as Figure 6 As shown, the width of the first guide wheel 31 is greater than the width of the hanging hole 111.

[0050] In a further embodiment, such as Figure 3 , Figure 5 and Figure 6 As shown, the guiding mechanism 3 further includes multiple sets of second guide wheels 32, which are rotatably disposed on the side of the hanger 22. At least two sets of second guide wheels 32 are provided on each side of the hanger 22, and the two sets of second guide wheels 32 on one side of the hanger 22 form a clamping space 321 in the transverse direction. The upright beam 11 is located in the clamping space 321. The upright beam 11 has a second side 11b and a third side 11c. The second side 11b and the third side 11c are both adjacent to the first side 11a, and the second side 11b and the third side 11c are opposite sides. The two sets of second guide wheels 32 on one side of the hanger 22 slide against the second side 11b and the third side 11c respectively.

[0051] Specifically, in this embodiment, the upright beam 11 is made of square steel, and the second side 11b and the third side 11c are perpendicular to the first side 11a. By clamping the upright beam 11 on the second side 11b and the third side 11c with two sets of second guide wheels 32 respectively, the swaying of the suspended platform 2 can be prevented, ensuring the stability of the position of the suspended platform 2 and improving the safety and stability of the workers in high-altitude operations.

[0052] The above-mentioned solutions are specific, such as Figure 3 As shown, the work platform 21 is equipped with a guardrail 211 to provide protection for the workers on the work platform 21. The guardrail 211 has an entrance / exit (not shown) for workers to enter / leave the work platform 21.

[0053] Specifically, to facilitate the hanging of the frame 22 by the electric hoist 12, as described above... Figure 3 As shown, the hanger 22 is a gantry-type support, and the top of the hanger 22 is provided with a lifting lug 221, and the electric hoist 12 is connected to the lifting lug 221.

[0054] In some embodiments, such as Figure 2 As shown, the base frame 1 is connected to a connecting frame 5 that extends to the side, and the connecting frame 5 is mounted on the mobile vehicle body 6; wherein, the base frame 1 can be moved by the mobile vehicle body 6, so that the suspended basket 2 can move along the length of the bridge deck and adjust the construction section.

[0055] Of course, in other embodiments, the connecting frame 5 can also be directly fixed to the bridge surface.

[0056] In summary, this application provides a construction platform for highway bridge engineering. This platform, by installing an electric hoist 12 on the base frame 1, allows for precise control of the lifting and lowering of the suspended platform 2, enabling flexible adjustment of the working height of the platform 21. This effectively solves the problem of inconvenience caused by the inability to adjust the working height of the existing platform 21, meeting the diverse needs of different construction tasks for working height. Simultaneously, a guide mechanism 3 allows the hanging frame 22 and the upright beam 11 to slide vertically, providing stable guidance for the lifting and lowering of the suspended platform 2 and ensuring the smoothness of the lifting process. Furthermore, a padlock mechanism 4 can lock onto the upright beam 11 when the suspended platform 2 reaches a suitable height, enhancing the stability of the suspended platform 2, preventing accidental shaking or falling, and reducing the load on the electric hoist 12, thus providing a safer and more reliable working environment for construction personnel.

[0057] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0058] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
