[0001] The present invention relates to the technical field of bridge construction hanging baskets, in particular to a movable construction hanging basket attached to a bridge. Background Art

[0002] In bridge construction, the application of mobile construction hanging basket is a key technical means to resolve the contradiction between safety and efficiency of high-altitude operations.

[0003] Traditional construction methods are mainly carried out through fixed hanging baskets, which have the following pain points:

[0004] Difficulty in relocation: The entire structure needs to be disassembled and reassembled after completing each section of work, and a single relocation takes 2-3 hours (for example, the painting of bridge piers requires more than 20 relocations).

[0005] Large blind spots in coverage: The curved surfaces of bridge piers, areas below expansion joints and other areas cannot be fitted, requiring manual climbing and supplementary work, which increases the accident rate by 40%.

[0006] Weak risk resistance: construction must be stopped when wind speed is greater than level 6, resulting in an average annual construction delay of more than 15 days.

[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] Example: Please combine Figures 1-6 A movable construction hanging basket attached to a bridge in this embodiment includes a pier 9 and a work platform hoisted at the pier 9.

[0032] The working platform is composed of four mobile hanging baskets that are spliced ​​and symmetrical to the bridge pier 9. The mobile hanging basket is composed of a horizontal rectangular base plate 1 and a fence 2 fixedly connected to the top of the short side and long side of one side of the base plate 1. The fences 2 are all set on the outside. The short sides of the two base plates 1 on the same side without the fence 2 are fixed with bolts. The base plates 1 and fences 2 connected adjacent to each other constitute the working platform.

[0033] An outer crossbeam 3 and an inner crossbeam 6 are respectively provided on the top of the movable hanging baskets symmetrically on both sides of the pier 9. The outer crossbeam 3 and the inner crossbeam 6 are arranged just above the short side of the base plate 1, wherein the outer crossbeam 3 is arranged outside the inner crossbeam 6. Four vertical screws 4 are symmetrically threaded on both sides of the base plate 1. Among them, the two vertical screws 4 close to the pier 9 are rotatably connected to the wheels 5, and the two wheels 5 are in contact with the side surfaces of the pier 9.

[0034] A supporting and positioning mechanism is provided between the two inner cross beams 6, which is used to quickly support the work platform according to the protrusions 10 on both sides after the work platform is hoisted, and to achieve positioning and stabilization of the entire work platform.

[0035] The adjacent outer beams 3 and inner beams 6 are symmetrically fixedly connected with connecting rods 7 on both sides of the pier 9, and after the working platform is hoisted, U-shaped clamps need to be installed at the connection points of the connecting rods 7 on both sides of the outer wall of the outer beam 3. The outer beams 3 and the inner beams 6 are symmetrically fixedly connected with positioning sleeves 8 on both sides of the pier 9. The top of each positioning sleeve 8 is connected to a steel cable, and the top of each steel cable is connected to a lifting ring.

[0036] The fences 2 on both sides of the pier 9 are connected to connecting arms extending along the width direction of the base plate 1, which are used to connect the base plates 1 on both sides of the pier 9 to further maintain stability.

[0037] The supporting and positioning mechanism includes a connecting frame 11 symmetrically fixedly connected to both sides of the two inner beams 6. The connecting frame 11 is arranged along the length direction of the base plate 1. Four slide slot holes are symmetrically opened in the two inner beams 6. The slide slot holes extend in the same direction as the connecting frame 11. The two slide slot holes on the same side belong to a group. Two slide plates 12 are horizontally slidably connected in the two groups of slide slot holes. The outer sides of the two groups of slide plates 12 are rotatably connected to abutment wheels 13. The outer ends of the two groups of abutment wheels 13 abut against the protrusions 10.

[0038] The two groups of slides 12 are located in the inner cross beam 6 and are fixedly connected to the guide plate 14. The middle part of the two inner cross beams 6 is fixedly connected to the positioning plate 16. The positioning plate 16 is located between the two guide plates 14 and slides horizontally with the guide plates 14. The guide plates 14 are located on both sides of the positioning plate 16 and have guide grooves 15 symmetrically opened. The guide grooves 15 are arranged along the extension direction of the inner cross beam 6.

[0039] A hydraulic rod 22 is fixedly connected to the outer wall of one of the connecting frames 11, and the telescopic end of the hydraulic rod 22 is fixedly connected to the side plate 23, the bottom end of the side plate 23 is fixedly connected to the cross plate 24, and the bottom end of the cross plate 24 is symmetrically fixedly connected to the sliding column three 25. The hydraulic rod 22 is installed along the extension direction of the inner cross beam 6, and the cross plate 24 is arranged along the extension direction of the connecting frame 11.

[0040] The supporting positioning mechanism also includes a rotating plate 18 and a rotating plate 20. The middle parts of the rotating plate 18 and the rotating plate 20 are rotatably connected to the rotating rod 17. The rotating rod 17 is fixedly connected to the top of the positioning plate 16. The two ends of the rotating plate 18 are fixedly connected to the sliding column 19. The two sliding columns 19 are respectively slidably connected to the staggered guide grooves 15. The two ends of the rotating plate 20 are fixedly connected to the sliding column 21. The two sliding columns 21 are respectively slidably connected to another staggered guide groove 15. The rotating plate 18 and the rotating plate 20 are fixedly connected to the sliding column 21. The two plates 20 are identical, and both the rotating plate 18 and the rotating plate 20 are provided with an adaptive slide groove 26 at the bottom of the horizontal plate 24. The adaptive slide groove 26 is arranged along the extension direction of the rotating plate 18 / the rotating plate 20. The two adaptive slide grooves 26 are respectively slidably connected to the two ends of the slide column 3 25, and are used to drive the slide plates 12 on both sides to expand / store synchronously when the hydraulic rod 22 is extended or retracted, so as to quickly realize the support and positioning of the protrusion 10, and the working platform is lifted and slid under the sliding of the abutting wheel 13 and the protrusion 10.

[0041] The installation steps of the work platform are as follows:

[0042] S1. Assemble the mobile hanging basket (such as Figure 2 As shown, it accounts for 1 / 4 of the complete working platform);

[0043] S2. Hoist the half-side working platform consisting of the two mobile hanging baskets on both sides of the pier 9, and the outer crossbeam 3 and the inner crossbeam 6 connected in a coordinated manner, onto the pier 9. The runner 5 can be used to achieve contact with the outer wall of the pier 9 to maintain stability during the subsequent hoisting and movement.

[0044] S3. Similarly, assemble the other half of the work platform on the ground and then hoist it onto the bridge pier;

[0045] S4. After the working platform is symmetrically adjusted, the supporting positioning mechanism is used to abut against the protrusion 10 to keep the entire working platform stable.

[0046] The implementation principle of a bridge-attached movable construction hanging basket in the embodiment of the present application is as follows:

[0047] After the platform is installed in sequence, the entire / half platform is lifted directly to the bridge pier 9 by steel cables, and then the two sides of the outer beam 3 are gradually stabilized by installing U-shaped clamps and the connecting arms at the bottom.

[0048] After the overall installation is completed, the working platform and the two sides of the bridge pier 9 are in rolling contact through the wheels 5, which ensures the stability of the working platform during movement and operation, and is not easy to shake along the width direction of the base plate 1. Secondly, under the action of the supporting and positioning mechanism, the working platform can be guaranteed to shake along the length direction of the base plate 1, thereby further improving the working platform's ability to cope with the impact of wind during high-altitude operations and improving the work quality of workers when working on the working platform.

[0049] When hoisting and placing, place the support and positioning mechanism at the center of the two protrusions 10. At this time, the two sets of slides 12 are in the storage state. At this time, after the wheel 5 is in contact with both sides of the pier 9, continue to adjust the position of the working platform and gradually release the working platform downward so that the two sets of abutment wheels 13 are located at the center of the two protrusions 10. At this time, the hydraulic rod 22 can be started to realize the contraction of the entire hydraulic rod 22 (state reference Figure 5 The retracted state of the hydraulic rod 22 will cause the slide plates 12 on both sides to be stretched open, and the extended state of the hydraulic rod 22 will cause the slide plates 12 on both sides to be retracted inward), thereby utilizing the sliding column three 25 to slide along the two adaptive slide grooves 26 toward the rotating rod 17, thereby making the rotating plate 18 and the rotating plate 2 20 slide synchronously in the state of rotational connection, and pushing the two sets of guide plates 14 to slide outward, and finally realizing the abutment of the abutment wheel 13 with the protrusion 10. In this process, the entire working platform will be fine-tuned to ensure that the abutment wheel 13 and the protrusion 10 abut the lower working platform.

[0050] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
