[0039] See also Figure 1 and Figure 2 On one hand, the embodiment of the present application provides a construction device for the outer side of a municipal bridge railing, which is mainly used for construction work on the outer side of a municipal bridge railing 11. It mainly includes a walking mechanism and a hanging basket 10. The walking mechanism is used to walk on the road surface of the municipal bridge, and the hanging basket 10 is used to accommodate construction workers for construction work. The walking mechanism is provided with a cantilever rod 5 toward the outer side of the railing 11, and one end of the cantilever rod 5 is fixed to the upper part of the walking mechanism; the upper part of the hanging basket 10 is fixedly connected to the other end of the cantilever rod 5. The above-mentioned construction device for the outer side of the municipal bridge railing rigidly connects the walking mechanism and the hanging basket 10 through the cantilever rod 5. When the walking mechanism is located on the road surface, the hanging basket 10 is ensured to be cantilevered on the outer side of the railing 11, providing a movable construction platform for construction workers, ensuring the safety of high-altitude operations, and the movable design can provide construction efficiency. The above-mentioned construction device for the outer side of the municipal bridge railing can reduce safety risks in the construction of the railing 11, ensure the safety of construction workers, reduce construction costs, and speed up construction progress.

[0040] See also Figure 1 and Figure 2 In some embodiments, the walking mechanism includes a main frame, and the bottom of the main frame has walking wheels for walking. The main frame is mainly connected to a rectangular structure by a plurality of vertical poles 1 and a plurality of horizontal poles 2. Connectors 3 are used to connect the vertical poles 1 and the horizontal poles 2 at the corners of the rectangular structure, and the horizontal poles 2 are connected to each other. The overall steel structure frame is low in cost and stable in structure.

[0041] Further, see Figure 3 and Figure 4 The ends of the vertical pole 1 and the horizontal pole 2 are both provided with spring buckles 13, and the connector 3 has a plurality of connecting ends, which are hollow structures and have clamping holes 12 that cooperate with the spring buckles 13. The vertical pole 1 and the horizontal pole 2 are respectively plugged and matched with the corresponding connecting ends, and are fixed by the spring buckles 13 and the clamping holes 12. The spring buckles 13 on the vertical pole 1 and the horizontal pole 2 cooperate with the clamping holes 12 on the connector 3 to form a stable and complete main frame, which can be quickly disassembled and installed and transported during the construction of the railing 11, and can well solve the problem of difficult construction on the outside of the railing.

[0042] Furthermore, one end of the cantilever rod 5 is also provided with a spring buckle 13, and the connector 3 is also provided with a connection end that cooperates with the cantilever rod 5. The cantilever rod 5 and the walking mechanism are also connected by a spring buckle 13 that cooperates with a clamping hole 12 on the connector 3, which further improves the flexibility of the device and facilitates quick disassembly, installation and transportation during construction.

[0043] See also Figure 1 and Figure 2In some embodiments, the traveling wheel adopts a universal wheel 4 with a brake. The universal wheel 4 is installed at the bottom of the device for free movement of the device along the direction of the railing 11. The brake is used to prevent the universal wheel 4 from sliding during the construction process, thereby stabilizing the device.

[0044] See also Figure 1 In some embodiments, a paint-proof cloth 9 is disposed on one side of the main frame facing the railing 11 to prevent paint splashing when the railing 11 is sprayed with paint, thereby preventing the bridge deck from being contaminated.

[0045] See also Figure 1 and Figure 2 In some embodiments, the walking mechanism further includes a lighting assembly for lighting the railing 11. The lighting assembly mainly includes an energy-saving lamp 8 and a storage-control integrated battery 7. The energy-saving lamp 8 is electrically connected to the storage-control integrated battery 7, and the energy-saving lamp 8 is installed on the cantilever rod 5. It is mainly used for construction lighting when the light is dim.

[0046] Furthermore, the lighting assembly also includes a solar panel 6, which is electrically connected to the storage and control integrated battery 7, and is connected in series to form a lighting system for construction lighting in dim light. This combination can achieve energy self-sufficiency in places with sunlight, reducing the user's dependence on the public power grid, and is particularly suitable for remote areas or places with unstable power supply.

[0047] Furthermore, we can also install the integrated storage and control battery 7 and the solar panel 6 on the walking mechanism, and both are located at the end away from the hanging basket 10 to form a counterweight to prevent the hanging basket 10 from overturning and play a role in stabilizing the structure.

[0048] In some embodiments, a counterweight assembly (not shown in the figure) is configured on the walking mechanism, and the counterweight assembly is located at one end away from the hanging basket 10 to prevent the hanging basket 10 from overturning and play a role in stabilizing the structure.
