Description

Technical Field

[0001] The present application relates to the technical field of building bridge construction, and in particular to a construction, decoration and maintenance platform for bridge piers. Background Art

[0002] Bridges are important structures in the fields of highways, railways, and municipal administration, playing important roles in traffic and water transportation. In the projects in these fields, a large number of bridge structures will be under construction, among which piers are an important part of bridges. Piers are divided into cylindrical piers, hollow piers, gravity piers, etc., among which cylindrical piers are the most common.

[0003] During the construction of cylindrical piers, the degree of formwork polishing, the quality of the release agent, the quality of the concrete, the quality of the vibration, the degree of maintenance, or the omissions in the protection of the finished product may still lead to honeycombed surfaces, missing edges and corners on the surface of the piers even when the construction steps and requirements are strictly controlled. Therefore, corresponding modifications are required. In addition, according to the pier maintenance requirements, wrapping maintenance is required in areas that are not suitable for spray maintenance. Therefore, lifting equipment with a platform is required for high-altitude operations.

The ring-shaped hanging point frame is installed on the crawler, and the operating platform is hoisted on the ring-shaped hanging point frame by a wire rope, and the operating platform can be lifted up and down along the completed bridge piers. The bridge cap beam construction system can reduce the workload of workers in high-altitude operations, reduce the risks of high-altitude operations, and improve construction efficiency.

[0005] Although a guide roller group is provided on the inner side of the above-mentioned operating platform, it lacks a stable structure. When the operating platform temporarily stays in the air, the construction workers walking on the operating platform can easily cause it to shake, which makes it inconvenient for the construction workers to decorate and maintain the surface of the pier. The stability of the operating platform is poor and it is difficult to meet the requirements of pier decoration and maintenance. Summary of the invention

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0031] The embodiment of the present application provides a construction, decoration and maintenance platform for bridge piers, which can solve the problem in the related art that the operating platform has poor stability and is difficult to meet the requirements for pier decoration and maintenance.

[0033] An annular platform 10, which is used to be arranged on the periphery of a bridge pier;

[0034] A guide mechanism 20, comprising guide wheels 21 spaced apart inside the annular platform 10 and used to contact the surface of the bridge pier;

[0035] The clamping mechanism 30 includes a clamping member 31 located inside the annular platform 10 and a driving assembly 32 for driving the clamping member 31 to fit with the surface of the bridge pier.

[0036] The construction, modification and maintenance platform for bridge piers according to the embodiment of the present application includes an annular platform 10 for being arranged on the periphery of the bridge pier, and a guide mechanism 20 and a clamping mechanism 30 are provided on the annular platform 10. The guide mechanism 20 includes a guide wheel 21 which is arranged at intervals on the inner side of the annular platform 10 and is used to contact the surface of the bridge pier, and is used to support and guide the annular platform 10 when it is raised or lowered. The clamping mechanism 30 includes a clamping member 31 located on the inner side of the annular platform 10, and a driving assembly 32 for driving the clamping member 31 to fit the surface of the bridge pier.
