[0002] Bridge guardrails are a series of protective features installed on bridges to prevent uncontrolled vehicles from running over the bridge. They also prevent vehicles from breaking through, passing under, or climbing over the bridge, and beautify the bridge structure. In addition to their safety and protection functions, bridge guardrails also enhance the aesthetics of the bridge, making it more harmonious with the surrounding environment. The material selection for bridge guardrails should take into account strength, durability, and coordination with the bridge structure. Commonly used materials include metal beams and columns, reinforced concrete, etc. Bridge guardrails are constructed in a variety of forms, including beam-column, wall, and combination types. The most appropriate form should be selected based on the specific bridge type and geographical location.

[0003] When making reinforced concrete bridge guardrails at the construction site, it is necessary to install guardrail formwork on the edge of the bridge and then pour reinforced concrete. Personnel are required to fix the formwork on the outside of the bridge, and a formwork installation auxiliary platform made of specific steel bars is required to facilitate construction workers to fix the formwork.

[0004] However, the auxiliary platform for installing the template made of steel bars on site is made with specifications and dimensions according to the dimensions required on site. It is a specific tool and needs to be remade when used on other bridges, which is time-consuming and labor-intensive. Moreover, the on-site production has not been tested and has a low safety factor. In view of this, the present application proposes a simple operating platform for bridge guardrail construction. Utility Model Content

[0007] A winch is fixedly installed on the top of the sliding platform, a guide wheel is rotatably installed on the top of the sliding platform through a bracket, a steel rope is fixedly installed on the output end of the winch, and a hanging basket is fixedly installed on one end of the steel rope through the guide wheel.

[0008] Furthermore, a movable motor is fixedly mounted on one side of one of the mounting side plates, and an output shaft of the movable motor is fixedly connected to one end of the rotating shaft.

[0009] Furthermore, a support vertical plate is fixedly installed between the two support columns and at the bottom of the two partition plates, and a through hole adapted to the movable rack is opened on one side of the support vertical plate.

[0010] Furthermore, limit baffles are fixedly installed on both ends of the movable rack, and top plates are fixedly installed on the top ends of the four support columns.

[0011] Furthermore, a stabilizing sleeve is fixedly installed on the top of the sliding platform, and a stabilizing guide rod is slidably installed inside the stabilizing sleeve.

[0012] Furthermore, the bottom end of the stabilizing guide rod is fixedly connected to the hanging basket, and the top end of the stabilizing guide rod is fixedly installed with an end plate.

[0013] Furthermore, universal movable wheels are rotatably mounted at the four corners of the bottom of the sliding platform through brackets, and a counterweight is fixedly mounted on the top of the sliding platform.

[0014] Compared with the existing technology, the utility model provides a simple operation platform for bridge guardrail construction, which has the following beneficial effects:

[0015] The bridge guardrail construction has a simple operating platform. The gears are controlled by a mobile motor to drive the sliding platform to move. The hanging basket is moved to the outside of the bridge, and then the hanging basket is lowered to a suitable position by a winch. The position of the hanging basket can be adjusted according to the on-site environment to facilitate the installation of the guardrail formwork. This solves the problem of using steel bars to process the formwork on site to install the auxiliary platform. The specifications and dimensions are made according to the dimensions required on site.

The hoist 9 then releases the steel rope 11 to lower the hanging basket 12 to the desired position.

[0025] At the same time, a support vertical plate 14 is fixedly installed between the two support columns 2 and at the bottom of the two partition plates 3. A through hole 14 is opened on one side of the support vertical plate 14 to match the movable rack 5. The movable rack 5 moves between the two partition plates 3 and meshes with the control gear 8 below the two partition plates 3.

[0026] Wherein, limit baffles 15 are fixedly installed on both ends of the movable rack 5 , and top plates 16 are fixedly installed on the top ends of the four support columns 2 .
