Among them, installing suspended platforms on high piers or on piers where the beams have already been erected presents a major challenge for builders. For high piers, the traditional crane hoisting method for operating platforms is unsafe due to the excessive lifting height and is also very inconvenient to use. After the beams have been erected, the traditional suspended platform method faces the problem of the beams above the pier obstructing the view and insufficient space above, making it impossible to install the operating platform. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a lifting operation platform that can conveniently and safely install hanging railings on high or already erected bridge piers.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a lifting operation platform for installing a bridge pier hanging fence, comprising a walking platform, an electric hoist, a fixed steel wire rope and a hanging steel wire rope. The walking platform is circular and surrounds the outside of the bridge pier. Four electric hoists are fixed on the walking platform. The four electric hoists are arranged in pairs and located on both sides of the bridge pier. Each electric hoist is located on the extended line of the center line of the two pad stones.

[0005] Two fixed steel wire ropes are respectively wrapped around two pad stones. Two hanging steel wire ropes are symmetrically connected to each fixed steel wire rope. The upper end of the hanging steel wire rope is connected to the fixed steel wire rope, and the lower end hangs down to the side of the pier and is connected to the hook of the electric hoist located directly below it.

[0006] Furthermore, the walking platform includes a walkway at the bottom and a guardrail fixed to the outside of the walkway.

[0007] Furthermore, the walking platform includes two straight segments and two curved segments. The two straight segments are arranged in parallel, and the two curved segments are located at the two ends of the two straight segments respectively. The two ends of each curved segment are detachably connected to the corresponding ends of the two straight segments to form a ring.

[0008] Furthermore, the walkway is paved with steel grating.

[0034] like Figure 6 As shown, the walking platform 1 includes two straight segments 13 and two curved segments 14. The two straight segments 13 are arranged in parallel, and the two curved segments 14 are located at the two ends of the two straight segments 13 respectively. The two ends of each curved segment 14 are detachably connected to the corresponding ends of the two straight segments 13 to form a ring. The walking platform 1 is a detachable and assembleable modular design, which allows the walking platform 1 to be disassembled and transferred to another bridge pier for reuse, thus saving resources.

[0035] The walkway 11 is paved with steel grating.

[0036] like Figure 1 , Figure 2 , Figure 3 As shown, this utility model also includes a channel steel corner protection system, which includes multiple vertical corner protectors 5 and multiple horizontal corner protectors 6;

[0037] A vertical corner protector 5 is installed at the bottom of each of the four corners of the two pad stones 8. The vertical corner protector 5 is placed between the pad stone 8 and the fixing steel wire rope 3. The vertical corner protector 5 protects the concrete structure at the four corners of the pad stone 8 from being damaged by the fixing steel wire rope 3.

[0038] A horizontal corner guard 6 is installed at each point where the top edge of the pier 7 contacts the hanging steel wire rope 4. The horizontal corner guard 6 is positioned between the top edge of the pier 7 and the hanging steel wire rope 4. The horizontal corner guard 6 protects the concrete structure at the top edge of the pier 7 from being damaged by the hanging steel wire rope 4.

[0039] Both the vertical corner protector 5 and the horizontal corner protector 6 are right-angle structures formed by welding two channel steels together.

[0040] like Figure 4 As shown, a ring 41 is fixed to the lower end of the drooping steel wire rope 4, and the hook of the electric hoist 2 is hooked on the ring 41.

[0041] The electric hoist 2 is fixed on the center line of the walking platform 1.

[0042] The electric hoist 2 mentioned above is a mini electric hoist.

[0043] The installation process of this utility model is as follows.

[0044] Step 1: Install the walking platform 1.

[0045] A walking platform 1 is welded around the pier 7 using I-beams and angle steel on a flat ground. The overall inner width of the walking platform 1 is 0.8 meters greater than the width of the pier, and the overall inner length is 1 meter greater than the length of the pier. The curved sections 14 on both sides are smoothly set according to the dimensions. The walkway 11 at the bottom of the walking platform 1 is paved with a 1-meter-wide steel grating and welded firmly to the angle steel. A guardrail 12, made of angle steel and 1.25 meters high, is fixed to the outside of the walking platform 1 and surrounds the walking platform 1. During construction, holes are drilled in the four angle steels at the ends of the straight section 13 and the curved section 14, and then the angle steels are fixed together with bolts to form a ring, which facilitates the installation and disassembly of the walking platform 1. Double nuts are used during use to ensure the stability and safety of the walking platform 1.

[0046] Step 2: Install and fix the steel wire rope 3 and the drooping steel wire rope 4.

[0047] First, prepare 24 10cm long channel steels, weld them in pairs to form right angles, creating 8 vertical corner protectors 5 and 4 horizontal corner protectors 6. Place the 8 vertical corner protectors 5 at the four corners of the two foundation stones 8 to protect the concrete structure at the corners of the foundation stones 8. Then, wrap the fixing wire rope 3 around the foundation stone 8 at least two turns, skipping the vertical corner protectors 5, and secure it firmly with knots. Install a hanging wire rope 4 on each side of the foundation stone 8, for a total of four hanging wire ropes 4 for the two foundation stones 8. The upper end of each hanging wire rope 4 is connected to the fixing wire rope 3, and the lower end has a loop 41, hanging down from the side of the pier. The hanging wire ropes 4 are symmetrically arranged in pairs on the side of the pier, and must be positioned along the center line of the foundation stone 8. Four horizontal corner protectors 6 are placed on the edge of the pier top to separate the dangling steel wire rope 4 from the edge of the pier top. Grooves or holes for placing the dangling steel wire rope 4 can be provided on the horizontal corner protectors 6, which serves to protect the concrete structure at the edge of the pier top and fix the position of the dangling steel wire rope 4. The length of the dangling steel wire rope 4 is determined according to the construction position, ensuring that the traveling platform 1 can reach the construction position after the electric hoist 2 is wound up.

[0048] Step 3: Install the electric hoist 2.

[0049] Four mini electric hoists are symmetrically arranged on the walkway 11 of the walking platform 1, with the hoists positioned along the center line of the walkway 11. The width between two mini electric hoists on the same side is equal to the width between the centers of two foundation stones 8, and the relative positions of the two mini electric hoists on opposite sides are symmetrical. After the four mini electric hoists are placed, they are securely fixed to the walkway 11 of the walking platform 1. After the use of a bridge pier 7 is completed, the mini electric hoists do not need to be removed and can be installed and dismantled together with the walking platform 1.

[0050] Step 4: Assembly.

[0051] Install the walking platform 1 around the bridge pier 7. Then, connect the hanging steel wire ropes 4 with rings 41 on both sides of the pad stone 8 to the corresponding hooks of the mini electric hoists, and install anti-disengagement devices. After connection, conduct a safety inspection to ensure that the walking platform 1 and the electric hoist 2 are secure and stable, and that all steel wire ropes are straight, smooth, and without breaks. Once preparation is complete, simultaneously start four mini electric hoists. The retraction of the hoist ropes will lift the walking platform 1. When it reaches the construction position, turn off the mini electric hoists and begin the hoisting fence construction. After construction is completed, simultaneously start four mini electric hoists to lower it, controlling the descent speed and ensuring a slow landing.

[0052] Step 5. Disassembly.

[0053] Once the construction of a bridge pier 7 is completed and the walking platform 1 is stably placed on the ground, this utility model can be disassembled. During disassembly, first separate the hanging steel wire rope 4 from the top of the pier and the mini electric hoist, remove the horizontal corner guard 6, the fixing steel wire rope 3 on the pad stone 8 and the vertical corner guard 5, then loosen the bolts between the two straight sections 13 and the two curved sections 14 of the walking platform 1, disassemble the walking platform 1, and after disassembly, it can be transferred to the next bridge pier 7 for assembly construction.

[0054] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
