Description

Technical Field

[0001] This utility model belongs to the field of bridge construction, and specifically relates to a safe operating platform for bridge construction. Background Technology

[0002] After the installation of medium and large bridge beams, the traditional method is for workers to work from below the bridge deck to the top of the cap beam in an open-air environment. This traditional construction process exposes workers directly to the open surface, posing significant safety risks. As bridge construction progress demands increase and the construction period needs to be compressed as much as possible, coupled with the deteriorating construction environment, the aging workforce, and declining safety awareness, frontline workers are increasingly less adept at wearing safety belts properly. This leads to greater safety hazards when working on the open surface at the top of the cap beam. The development of the crossbeam operating platform not only ensures the safety of workers on the top of the cap beam during construction but also promotes standardized construction and provides strong support for accelerating the construction progress.

[0003] Chinese patent publication number CN222666584U discloses a bridge construction safety operation platform, including a base; multiple hydraulic rods are mounted on the top of the base; the construction platform body is mounted on top of the hydraulic rods; a fixing component is mounted on the base, comprising: a rectangular shell symmetrically penetrating the base at its bottom and fixedly connected to the base; rectangular rods disposed inside the rectangular shell; a plate disposed at the bottom of the rectangular rods; multiple insert rods disposed at the bottom of the plate; and threaded rods penetrating the rectangular rods and the rectangular shell at their top, threadedly connected to the rectangular rods and rotatably connected to the rectangular shell. This operation platform, through the fixing component, can fix the base, preventing the base from moving during construction and endangering the safety of workers. Compared to existing devices, it is simpler and more convenient to operate, and more efficient. The platform, through the design of a protective net, can protect the meshing of gear one and gear two, preventing accidental contact by workers.

[0004] As can be seen from the above structure, the base can be fixed by the fixing components to prevent the base from moving during construction and endangering the safety of the workers. However, the above device cannot be used properly when applied to high bridges, and the area of ​​the construction platform body cannot be flexibly adjusted during use, which is particularly inconvenient when multiple people need to operate it, thus reducing the flexibility and practicality of the device. Therefore, a safe operating platform for bridge construction is proposed. Utility Model Content

[0009] As a preferred technical solution, the support rod includes multiple support sleeve rods fixedly connected to the inner side of the side frame rod, and each support sleeve rod has a support insert rod inserted inside. The mounting plate includes a mounting sleeve plate disposed at one end of the side frame rod, and each mounting sleeve plate has a mounting insert plate inserted inside.

[0010] As a preferred technical solution, the protective backplate includes a first frame and a second frame disposed on the outside of the mounting sleeve. Insertion rods are inserted into the interior of both the first frame and the second frame. Protective nets are provided on both sides of the protective backplate. The protective net on the outside of the protective backplate is fixedly connected to the first frame, and the protective net on the inside of the protective backplate is fixedly connected to the second frame. The protective nets cover the first frame and the second frame.

[0011] As a preferred technical solution, each side of the suspension rod is connected to a front and rear rod, and the other end of the front and rear rod is fixedly connected to a left and right rod. Both sides of the protective back plate are provided with connecting sliding holes, and the left and right rods are connected to the connecting sliding holes.

[0012] As a preferred technical solution, the upper ends of the front and rear rods on one side of the suspension rod are provided with multiple limiting holes, the outer side of the suspension rod is provided with a sliding groove, the upper end of the sliding groove is fixedly connected with a push-out spring, the sliding groove is slidably connected with a sliding block, the other end of the push-out spring is fixedly connected with the sliding block, the lower end of the sliding block is fixedly connected with a limiting plug, and the limiting plug and the limiting holes are interlocked.

The first connecting plate and the second connecting plate are fitted together, and bolt groups are inserted into the inner sides of the first connecting plate and the second connecting plate.

[0014] In summary, the present invention has the following main advantages:

[0015] Firstly, this utility model, through its bottom component, allows for adjustment of the bottom support rod when multiple operations are required. By turning the rotating handle, the threaded column is rotated out of the threaded hole. After the threaded column rotates out, the locking block disengages from the locking hole. After disengagement, the length of the bottom component can be increased by pulling the sleeve rods on both sides. After the length of the bottom component is adjusted, the threaded column is connected to the threaded hole, and the locking block and locking hole are locked again to fix the bottom component. Thus, during use, the distance of the operating platform can be easily adjusted to increase the usable area. At the same time, the flexible expansion mechanism can quickly adjust the left and right distance of the operating platform according to actual work needs, adapting to different scale work scenarios.

[0016] Secondly, this utility model, through the side component, allows for adjustment of the front-to-back distance after the left and right positions are adjusted. By sliding the sliding block upwards, the locking block and the locking hole are disengaged. Then, the protective backplate is pushed outwards, causing the side frame rod to slide out of the support frame. This increases the front-to-back distance of the operating platform after the side frame slides. After sliding to the appropriate position, the sliding block is released, and the spring pushes the sliding block to engage the locking block and the locking hole. After engagement, the position of the protective backplate is fixed. Then, the spring-driven automatic locking structure is activated. After the sliding block resets, the locking block and the hole are tightly engaged, providing stable support for the protective backplate, effectively ensuring operational safety, and achieving a dual improvement in convenience and stability.

The support rod 53 is composed of the support sleeve rod 531 and the support plug rod 532, so that when the left and right position of the operating platform is adjusted, the support rod 53 can be adjusted with the bottom component 1, and then the front and back can be adjusted. By sliding the sliding block 15 upward, the locking block 16 and the locking hole 9 are released. Then, the protective back plate 55 is pushed outward so that the side frame rod 52 slides out of the inside of the support frame. After the side frame slides, the front and back distance of the operating platform can be increased. After sliding out to the appropriate position, the sliding block 15 is released. At this time, the spring 14 is pushed out to push the sliding block 15 so that the locking block 16 and the locking hole 9 are locked. After the plugging is completed, the position of the protective back plate 55 can be fixed. After the fixation is completed, the device can be used. The device can be moved to the bridge construction position by a crane. Then, it can be connected to the connecting steel bar group inside the cap beam or cross beam of the bridge through the installation end 3.
