Description

Technical Field

[0001] The present application relates to the field of construction tools, and in particular to a protective hanging basket for bridge construction. Background Art

[0002] After the main structure of the bridge is completed, it is usually necessary to carry out construction on the outside of the bridge, such as steel bar formwork construction, construction joint repair, and bridge electromechanical installation. When carrying out construction on the outside of the bridge, a hanging basket is needed to provide a safe construction platform for the construction workers.

[0003] In the existing related technologies, a hanging basket is usually recorded as described in the utility model announcement number CN 219260750 U, which is named "A bridge side construction hanging basket", including a counterweight mechanism, a connecting rod, a ladder and a hanging basket. The counterweight mechanism is arranged on the inner side of the bridge deck guardrail and connecting rods extending to the outer side of the bridge deck guardrail are installed on both sides of the top of the counterweight mechanism. The extended end of the connecting rod is installed with a ladder and the hanging basket is installed on the ladder.

[0004] The utility model is provided with a connecting rod installed on the top of the counterweight mechanism, a ladder installed on the connecting rod, and a hanging basket installed on the ladder. When in use, the installation position of the device needs to be determined according to the specific conditions of the bridge construction, and then the counterweight mechanism is assembled and placed inside the bridge deck guardrail. The ladder and the hanging basket are located outside the bridge deck guardrail, and the staff can enter the hanging basket through the ladder to carry out construction. Compared with traditional hanging basket equipment, this device occupies less space, is convenient to construct, and is easy to install.

[0005] With regard to the above-mentioned related technologies, the counterweight mechanism makes the weight of the hanging basket heavy and difficult to move, and the construction work surface is narrow, making it difficult for construction workers to carry out large-scale construction on the outside of the bridge. Summary of the invention

[0006] In order to expand the construction working area and thus facilitate construction workers to construct the outer side of the bridge, the present application provides a bridge construction protective hanging basket.

[0019] Optionally, the height of the wire mesh is greater than or equal to 500 mm.

[0020] By adopting the above technical solution, construction workers need to lift their calves to cross the wire mesh with a height greater than or equal to 500 mm, which makes it more difficult for construction workers to step out of the bottom plate of the hanging basket during construction, which is conducive to further ensuring the safety of construction workers.

[0021] Optionally, a plurality of the protective beams are distributed in the vertical direction, and a vertical distance between two adjacent protective beams is greater than 200 mm and less than 300 mm.

[0022] By adopting the above technical solution, the protective beam with a distance size greater than 200mm and less than 300mm, on the one hand, makes it convenient for construction workers to extend their hands out of the working space, thereby facilitating construction workers to carry out construction on the outside of the bridge; on the other hand, it is also convenient for construction workers to use the protective beam as a ladder to enter or leave the working space.

[0023] Optionally, the bottom pulley is arranged in a spindle shape.

[0024] By adopting the above technical solution, the outer bottom of the bridge is usually provided with an inclined surface, and the spindle-shaped bottom pulley is easier to effectively contact the inclined surface on the outer side of the bridge, thereby ensuring that the bottom pulley rolls stably along the bridge.

[0025] Optionally, the length of the connecting rod is greater than or equal to 500 mm.

[0026] By adopting the above technical solution, the connecting hanging rod with a length greater than or equal to 500 mm allows the construction workers to maintain a distance from the outer side of the bridge, thereby facilitating the construction workers to operate construction tools.

[0028] 1. When the bridge construction protection hanging basket is hung on the bridge guardrail and needs to be moved, the bridge construction protection hanging basket is pushed to make the transverse pulley, the top pulley and the bottom pulley roll along the length direction of the bridge, thereby making the working cavity accommodating the construction personnel move along the length direction of the bridge, thereby expanding the construction working surface and facilitating the construction personnel to carry out a larger range of construction on the outside of the bridge.

[0029] In addition, the materials selected for the protective columns, protective beams and connecting hanging rods are hollow steel pipes, which not only ensure the strength but also reduce the dead weight of the structure, making the bridge construction protective hanging basket easier for construction workers to push, thereby further facilitating the movement of the bridge construction protective hanging basket.

[0030] 2. After the bridge construction protection hanging basket is hung on the bridge guardrail, the construction workers enter the working space by holding the guardrail located at the top of the connecting hanging rod, which is conducive to ensuring the safety of the construction workers when entering the working space.

The height of the bottom plate bending portion 11 is greater than or equal to 150 mm, so as to block the feet of the construction workers so that the construction workers are not likely to step on empty space.

[0040] Reference Figure 2In the embodiment of the present application, the number of protective columns 2 is set to four, and the four protective columns 2 are distributed in a rectangular shape. The protective columns 2 are arranged in the vertical direction, and the bottom of the protective columns 2 is fixedly connected to the bottom plate 1 of the hanging basket, and the height of the protective columns 2 is greater than or equal to 2000 mm. In addition, an operation window 102 is opened between the two protective columns 2, and the operation window 102 is arranged near the bending portion 11 of the bottom plate. When the bridge construction protective hanging basket is hung on the bridge guardrail, the operation window 102 is set toward the bridge. The height of the operation window 102 is greater than 500 mm and less than 1500 mm, so as to ensure that the operation window 102 provides sufficient space for construction personnel to move around and makes it difficult for construction personnel to slip and fall from the operation window 102.
