[0001] This utility model relates to the technical field of construction scaffolding, and in particular to a construction scaffolding for highway bridges. Background Technology

[0002] Bridges generally refer to structures built over rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. To adapt to the modern, rapidly developing transportation industry, bridges have also been extended to refer to structures built across mountains, adverse geological conditions, or to meet other transportation needs, making travel more convenient. Currently, during the construction of highway bridges, due to their high location, suspended platforms are needed to move workers to suitable positions for construction in order to increase the safety of workers.

[0003] In the prior art, a highway bridge construction suspended platform disclosed in CN219117973U includes a workbench. Support frames are longitudinally bolted to the four corners of the upper part of the workbench, and lifting rings are integrally connected to the middle of the upper end of each support frame. First protective rods are integrally connected from top to bottom to the inner sides of the support frames on the left and right sides, respectively. Second protective rods are integrally connected from top to bottom to the inner sides of the support frames on the front and rear sides, respectively. The key feature is that a rotatable suspension structure is connected to the upper part of the workbench, and a self-locking electric lifting frame structure is connected to the front of the rotatable suspension structure. The design of the fixed sleeve, rotating shaft, quick-release bolt, operating ring, connecting rod, suspension frame, and self-locking electric lifting frame structure in this invention facilitates the safe lifting of tools.

[0004] This application facilitates the hoisting of tools from the ground into the basket, saving time for subsequent tool retrieval. However, when hoisting tools, the hoisting mechanism is located on the side of the basket. When hoisting and lifting the tools, the basket is prone to tilting and swaying, which may affect the safety of the workers in the basket. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a suspended platform for highway bridge construction, so as to solve the technical problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A suspended platform for highway bridge construction includes a base and a guardrail. The guardrail is fixedly installed on the top side of the base.

[0012] In a preferred embodiment, the present invention can be further configured such that the top side of the assembly box is aligned with the top side of the base.

[0013] In a preferred embodiment, the present invention can be further configured such that: two inclined plates are connected to the bottom side of the base, the assembly box is located between the two inclined plates, and the two inclined plates are arranged in a figure-eight shape.

[0014] In summary, this utility model has at least one of the following beneficial technical effects:

[0015] 1. In the case of this highway bridge construction scaffold, the assembly box can be lowered from the middle of the bottom side of the scaffold during use, avoiding the side of the scaffold which would affect the balance of the scaffold and cause swaying when loading and unloading items, thus affecting the safety of the workers. In addition, it also reduces the space occupied inside the scaffold and avoids obstruction of workers' work, thus achieving the effect of ensuring the safety of workers and avoiding interference with their work.

[0016] 2. The construction basket for highway bridges has a threaded connection between the support column and the top side of the guardrail. The lifting ring is fixedly installed on the top side of the support column and is used to cooperate with the hook of the hoisting machine to lift the basket to a suitable position during highway bridge construction, thereby facilitating subsequent construction work.

[0017] 3. In this type of highway bridge construction scaffold, after the top side of the assembly box is aligned with the top side of the base, the drive motor starts to release the wire rope, and at the same time the lifting motor starts, driving the gear shaft to rotate, which in turn drives the rack and assembly box to move upward. The released wire rope is prevented from getting tangled on the rotating shaft, thus pulling the assembly box and affecting its rise. After the gear shaft drives the assembly box to move onto the base, both the drive motor and the lifting motor stop. Then, the workers in the scaffold remove the items and materials from the assembly box. At this time, the drive motor drives the rotating shaft to retract the wire rope, and the lifting motor drives the assembly box back to its original position.

[0018] 4. In this type of suspended platform for highway bridge construction, the top side of the assembly box is aligned with the top side of the base to prevent the installation of the assembly box from causing protrusions or depressions on the top side of the base, which could cause workers to trip and affect their safety when working inside the suspended platform.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Example:

[0026] Reference Figures 1-3The present invention discloses a highway bridge construction gantry, including a base 1 and a guardrail 2. The guardrail 2 is fixedly installed on the top side of the base 1. A through groove 3 is provided in the middle of the top side of the base 1. An assembly box 4 is slidably connected in the through groove 3. Lifting components 5 are provided on the two opposite sides of the end of the base 1.

[0027] The lifting component 5 includes a drive motor 6, two bottom grooves 7, a rotating shaft 8, and steel wire ropes 9. The drive motor 6 is fixedly installed on the end side of the base 1. Two bottom grooves 7 are formed on the bottom side of the base 1. The rotating shaft 8 is fixedly installed on the output end of the drive motor 6. The end of the rotating shaft 8 extends into the two bottom grooves 7. There are two steel wire ropes 9, which are respectively arranged in the two bottom grooves 7. The steel wire ropes 9 are wound around the rotating shaft 8. The end of the steel wire ropes 9 extends into the through groove 3 and is connected to the assembly box 4. The end of the base 1 is also provided with a lifting component 11.

[0028] In this embodiment, when in use, the suspended platform is hoisted to the designated position for bridge construction. If tools other than those inside the suspended platform need to be used, the two drive motors 6 are started. The rotation of the two drive motors 6 will drive the rotation of the rotating shaft 8. The rotation of the rotating shaft 8 will release the steel wire rope 9, and the assembly box 4 will descend by its own weight. Since the four steel wire ropes 9 are fixed at the top of the corner of the assembly box 4, the assembly box 4 is prevented from shaking significantly, thus ensuring the stability of the assembly box 4.

[0029] After assembly box 4 descends to the ground, open assembly box 4, load the required items or materials into assembly box 4, close the box door, and start drive motor 6 again. Drive motor 6 pulls assembly box 4 to the bottom of base 1, and moves assembly box 4 to the top of base 1 through lifting component 11. Then, remove the items or materials from assembly box 4. At the same time, this mechanism can be used for elevator lifting, which can be used for workers to go up and down, ensuring the safety of workers.

[0030] In a further preferred embodiment of this utility model, such as Figure 2-3 As shown, the inner sidewall of the through groove 3 is provided with a clearance groove 12 for avoiding the steel wire rope 9, and the steel wire rope 9 is located in the clearance groove 12.

[0031] In this embodiment, the clearance groove 12 is used to avoid the steel wire rope 9, so as to prevent the steel wire rope 9 from getting stuck between the inner side wall of the through groove 3 and the assembly box 4 when it is released or tightened, thereby affecting the descent of the assembly box 4 and thus affecting the subsequent transport of items.

[0032] In a further preferred embodiment of this utility model, such as Figure 1As shown, four support columns 13 are connected to the top side of the guardrail 2, and a hanging ring 14 is connected to the top of the support column 13.

[0033] In this embodiment, the support column 13 and the top side of the guardrail 2 are threaded together. The lifting ring 14 is fixedly installed on the top side of the support column 13. The lifting ring 14 is used to cooperate with the hook of the hoisting machine so as to lift the basket to a suitable position in the construction of the highway bridge, thereby facilitating subsequent construction work.

[0034] In a further preferred embodiment of this utility model, such as Figure 2-3 As shown, the lifting component 11 includes a lifting motor 15, and a groove 16 is provided on the side of the assembly box 4. The output end of the lifting motor 15 is connected to a gear shaft 17, and the end of the gear shaft 17 extends into the groove 16. A rack 18 is connected to the inner wall of the groove 16, and the rack 18 meshes with the gear shaft 17.

[0035] In this embodiment, the lifting motor 15 is used to drive the rotation of the gear shaft 17, and then drive the rack 18 to move through the rotation of the gear shaft 17, so as to move the assembly box 4. When the assembly box 4 is lowered, the lifting motor 15 needs to be started to prevent the assembly box 4 from being stuck by the gear shaft 17.

[0036] When the assembly box 4 moves to the bottom of the base 1, the top of the groove 16 and the rack 18 inside will first fit against the gear shaft 17. Then the lifting motor 15 starts, driving the gear shaft 17 to rotate, which in turn drives the rack 18 to rise. At the same time, the driving motor 6 rotates, driving the rotating shaft 8 to retract the wire rope 9.

[0037] After the top side of the assembly box 4 is aligned with the top side of the base 1, the drive motor 6 starts to release the wire rope 9, and at the same time, the lifting motor 15 starts, driving the gear shaft 17 to rotate, which in turn drives the rack 18 and the assembly box 4 to move upward. The released wire rope 9 is prevented from getting tangled on the rotating shaft 8, thus pulling the assembly box 4 and affecting its ascent. After the gear shaft 17 drives the assembly box 4 to move onto the base 1, both the drive motor 6 and the lifting motor 15 stop. Then, the workers in the basket take out the items and materials from the assembly box 4. At this time, the drive motor 6 drives the rotating shaft 8 to retract the wire rope 9, and the lifting motor 15 drives the assembly box 4 back to its original position.

[0038] In a further preferred embodiment of this utility model, such as Figure 1-3 As shown, the top side of the assembly box 4 is aligned with the top side of the base 1.

[0039] In this embodiment, the top side of the assembly box 4 is aligned with the top side of the base 1 to prevent the installation of the assembly box 4 from causing the top side of the base 1 to protrude or dent, which could cause workers to trip when walking, thus affecting the safety of workers working in the suspended basket.

[0040] In a further preferred embodiment of this utility model, such as Figure 2 As shown, the bottom side of the base 1 is connected to two inclined plates 19, and the assembly box 4 is located between the two inclined plates 19. The two inclined plates 19 are arranged in a figure-eight shape.

[0041] In this embodiment, the inclined plate 19 is used to position the assembly box 4 when it rises. When the steel wire rope 9 is released or retracted, the assembly box 4 descends to the ground or retracts to the bottom of the base 1. Although it is positioned in four directions, there will still be a slight sway. Therefore, when the assembly box 4 rises, the top side of the assembly box 4 will touch the inclined plate 19 for guidance, so as to avoid the assembly box 4 from touching the bottom side wall of the base 1, thereby affecting the upward movement of the assembly box 4 and ultimately improving the stability of the assembly box 4 during use.

[0042] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
