Detailed implementation manners

[0029] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] In one embodiment, as Figures 1-8As shown in the figure, an adjustable hanging basket for bridge construction includes a construction bracket that fits the upper surface of the bridge. A hanging basket assembly is installed at the upper end of the construction bracket. The hanging basket assembly includes a number of support socket seats 56 installed on the upper end of the positioning base plate 11. Each support socket seat 56 is provided with a docking socket at the upper end, and a support column 52 is fitted in each docking socket. This plug-in method can quickly complete the quick docking of the hanging basket assembly and the construction bracket. A locking socket can also be provided on the outside of the support socket seat 56. An internal locking socket is provided on the surface of the support column 52. By inserting a pin into the internal locking socket and the locking socket, the connection of the components can be made more stable. An inclined fixed hanging basket arm 53 is erected between the support columns 52 on the upper end of the same positioning base plate 11. A number of grafting rods 51 are erected at equal intervals between two adjacent fixed hanging basket arms 53. A movable hanging basket arm 55 is slidably provided on the outside of each fixed hanging basket arm 53. A guiding chute 57 that matches the fixed hanging basket arm 53 is provided on the movable hanging basket arm 55. A limiting projection is provided on the inner wall of the guiding chute 57. Limiting grooves are distributed on the surface of the fixed hanging basket arm 53. The limiting projection and the limiting grooves are slidably arranged to prevent the movable hanging basket arm 55 from detaching from the fixed hanging basket arm 53. A positioning pin column 54 is movably inserted on the outside of the movable hanging basket arm 55. A number of positioning sockets that match the positioning pin column 54 are provided on the surface of the fixed hanging basket arm 53. By inserting the positioning pin column 54 into the positioning socket, the position between the movable hanging basket arm 55 and the fixed hanging basket arm 53 can be limited, thus playing a role in limiting and locking. A suspension installation beam 50 for installing a hoisting device is erected at the ends of the two movable hanging basket arms 55. Here, it is adjustable, which can facilitate fine-tuning the position of the suspension installation beam 50 after installation and positioning, avoiding the problem of excessive error, making the assembly more elastic. This adjustment method can also reduce the overall center of gravity position of the device, making it more stable during later movement and improving safety;

[0031] The construction bracket at least includes two positioning substrates 11 arranged in parallel. The two positioning substrates 11 are connected by a connecting component. At the end of each positioning substrate 11, there is a traveling wheel 12 for contacting the upper surface of the bridge. A pressure-bearing movable part is arranged between the traveling wheel 12 and the positioning substrate 11, and the pressure-bearing movable part is used to make the distance between the positioning substrate 11 and the bridge adjustable. An elevating guide rod 17 is arranged on the upper end of each positioning substrate 11. An elevating cross beam 20 is slidably arranged on the two elevating guide rods 17. An elevating guide sleeve 18 slidably matched with the elevating guide rod 17 is arranged on the elevating cross beam 20. A pushing side rod 14 is arranged outside the elevating guide sleeve 18. The pushing side rod 14 is connected to an elevating push rod 13 for driving it to move up and down. The lower end of the elevating push rod 13 is installed on the positioning substrate 11. A horizontal sliding sleeve 19 is slidably arranged at each end of the elevating cross beam 20. The horizontal sliding sleeve 19 is connected to a tightening mechanism for driving its sliding. An L-shaped rod 26 is arranged at the lower end of each horizontal sliding sleeve 19. A pressing-down component 27 for exerting a force on the lower side of the bridge is arranged at the lower end of the L-shaped rod 26. By exerting a force on the lower side of the bridge through the pressing-down component 27, the position of the positioning substrate 11 is fixed. When pressing tightly, due to the sufficient pressure, the bottom of the positioning substrate 11 is in direct contact with the bridge surface, ensuring the smoothness of the later construction;

[0032] The pressing-down component 27 includes a lower pressing plate 29. One side of the lower pressing plate 29 is provided with a connecting end connected to the L-shaped rod 26. A rolling part is arranged on the lower pressing plate 29 close to the bridge. A number of positioning pressing blocks 32 arranged at equal intervals are arranged on the upper end surface of the lower pressing plate 29. The positioning pressing blocks 32 are in a frustum structure with a larger upper part and a smaller lower part, so that the lower pressing plate 29 contacts the lower end surface of the bridge more stably. A moving switching part is also arranged on the lower pressing plate 29. When it is necessary to move the positioning substrate 11, the moving switching part can be switched to a rolling state, so that the positioning substrate 11 can move better;

[0033] The moving switching part includes a rectangular opening opened on the upper and lower end surfaces of the lower pressing plate 29. A lower pressing slider 30 is slidably arranged at the position of the rectangular opening. A number of mounting grooves are arranged at the upper end of the lower pressing slider 30. A pressing wheel 31 is rotatably arranged in each mounting groove. Two adjusting push rods 35 are symmetrically arranged at the lower end of the lower pressing plate 29 on both sides of the lower pressing slider 30. A pushing pressing rod 36 is arranged on the output ends of the two adjusting push rods 35. A cushion block 37 is padded between the pushing pressing rod 36 and the pressing surface 38 of the lower pressing slider 30. By driving the pushing pressing rod 36 to press the cushion block 37 through the adjusting push rod 35, the lower pressing slider 30 moves upward, so that the lower pressing plate 29 is converted into rolling contact with the lower end surface of the bridge. When the lower pressing slider 30 is retracted into the rectangular opening, the positioning pressing block 32 contacts the lower end surface of the bridge, thus completing the clamping and positioning;

[0034] The rolling members include side grooves 33 formed in the lower pressing plate 29, and a number of side pressing wheels 34 are rotatably provided in the side grooves 33. The multiple side pressing wheels 34 enable the lower pressing plate 29 to be in rolling contact when contacting the side of the bridge, facilitating subsequent movement.

[0035] A number of friction blocks matching the upper surface of the bridge are distributed at the lower end of the positioning substrate 11. In this way, when the positioning substrate 11 contacts the bridge surface, greater static friction can be provided, thereby improving the stability.

[0036] The tightening mechanism 16 includes a housing and shrinkage openings provided at both ends of the housing. The shrinkage openings are slidably matched with the pulling rods 15. A reset plate 41 is provided on the upper surface of the pulling rod 15, and the reset plate 41 is fixedly connected to the inner wall of the housing through a reset spring 42. Inside the housing between the two pulling rods 15, two coaxial winding discs 44 are provided. A fixed rotating shaft 43 rotatably connected to the inner wall of the housing is provided at the end of each winding disc 44. Traction ropes 46 are provided on both winding discs 44, and the winding directions of the two traction ropes 46 are opposite. The end of each traction rope 46 is fixedly connected to the traction rod at the end of the pulling rod 15. A worm gear 45 is coaxially provided at the middle position between the two winding discs 44. The worm gear 45 meshes with the worm 40, and the worm 40 is connected to a tightening motor 39 for driving its rotation. In this way, the worm 40 can be driven to rotate by the tightening motor 39, the worm 40 meshes with the worm gear 45, thereby driving the winding disc 44 to rotate, and then completing the winding of the traction rope 46. In this way, the two pulling rods 15 will be pulled closer, and the pulling rod 15 can provide power for the sliding of the horizontal sliding sleeve 19, so that the lower pressing assembly 27 clamps both sides of the bridge. A positioning pin 28 for inserting into the pulling hole on the surface of the horizontal sliding sleeve 19 is provided at the end of each pulling rod 15.

[0037] The connecting assembly includes a number of parallel connecting rods 22. Both ends of the connecting rods 22 are fixedly connected to the upper end surface of the positioning substrate 11. A connecting plate 21 is provided at the end of the connecting rod 22, and the connecting plate 21 is fixedly connected to the positioning substrate 11 through a number of bolts.

[0038] The pressure-bearing movable member includes a floating sleeve 25 provided on the upper end of the positioning substrate 11. A floating slider 23 is slidably provided in the sliding cavity outside the floating sleeve 25. An installation hole facilitating the installation of the traveling wheel 12 is provided on the outside of the floating slider 23. A guiding hole is provided on the floating slider 23, and the guiding hole is slidably arranged with a guiding rod inside the floating sleeve 25. The upper end of the floating slider 23 is fixedly connected to the inner top of the floating sleeve 25 through a floating spring 24. Under the action of the floating spring 24, the floating slider 23 drives the traveling wheel 12 to contact the upper surface of the bridge downward, thereby realizing the rolling contact between the positioning substrate 11 and the bridge, which provides a basis for subsequent rapid movement.

[0039] The above embodiment discloses a hanging basket construction bracket. During actual use, the positioning substrate 11 is placed on the upper end of the bridge through a hoisting device. Then, the horizontal sliding sleeve 19 is lifted, and the two horizontal sliding sleeves 19 are respectively sleeved on the lifting cross beam 20. Then, the end parts of the two pulling rods 15 are respectively connected and fixed to the horizontal sliding sleeve 19 through positioning pins 28. The two pressing components 27 are used to press the two sides of the bridge through a tightening mechanism. Then, the lifting push rod 13 drives the pushing side rod 14 to slide upward along the lifting guide rod 17, so that the lower end of the pressing component 27 is in pressing contact with the lower end surface of the bridge. When the pressure reaches the set value, the bearing movable part will give way a certain distance, so that the positioning substrate 11 is directly in contact with the upper end surface of the bridge. In this way, the overall fixation of the bracket is completed, which is convenient for the installation of the hanging basket in the later stage. When a local project is completed, the pressing component 27 and the bridge are in rolling friction through the moving switching part, and then the traction force of the lifting push rod 13 on the lifting guide rod 17 is reduced (at this time, it is also sufficient to maintain the stability of the bracket). At this time, the bearing movable part will make the traveling wheels 12 contact with the upper end surface of the bridge. In this way, the whole bracket and the bridge are in rolling contact, providing a basis for later movement. The moving and stabilizing methods provided in this application are simple and more convenient to switch, greatly improving the work efficiency. In addition, this operation method also makes the bracket modular, facilitating assembly and later disassembly, and having good recyclability.

[0040] The above is only the specific implementation manner of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present disclosure can easily think of changes or substitutions, which should all be covered by the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be subject to the protection scope of the claims.
