Description

Warning machine with lifting arm for construction

Technical Field

The invention relates to the technical field of building construction warning equipment, in particular to a warning machine with a lifting arm for building construction.

Background

The construction industry refers to the department of material production in national economy engaged in the exploration, design, construction of building installation projects and the maintenance activities on the original buildings. According to the classification catalog of the national economy industry, the building industry which is one of thirteen doors of the national economy consists of the following three major categories: civil engineering and construction; the line, pipeline and equipment installation industry, and the reconnaissance design industry. The function of the building industry is mainly to carry out building installation activities on various building materials, components, machine equipment and the like, and to build productive and non-productive fixed assets for national economy. The development of the construction industry has a close relationship with the fixed asset investment scale, and mutual promotion and mutual restriction are realized.

In the production of building industry, workers use mechanical equipment and tools to process and manufacture the working objects according to the design requirements, so that a certain product is produced, and the building industry has the characteristics of industrial production. However, it has many technical and economic features different from general industrial production, and thus is an independent material production department.

The building construction is a production process with complex technology, and building construction workers need to exert clever and talent intelligence to creatively apply theories such as materials, mechanics, structures, processes and the like to solve the technical problems which continuously appear in the construction, thereby ensuring the engineering quality and the construction safety. The construction process is carried out by multiple workers in limited time and space. The supply of hundreds of materials and the operation of various mechanical equipment, so that scientific and advanced organization and management measures and advanced construction processes are necessary to fully complete the production process, and the process is a process with higher economy. A great deal of manpower, material resources and financial resources are consumed in construction. Therefore, it is required to take measures to reduce the cost by considering the economic benefit everywhere in the construction process. The focus of attention in the construction process is always the quality of the project, the progress of safety (including environmental protection) and the cost.

The construction project of the house building comprises factory buildings, theaters, hotels, shops, schools, hospitals, houses and the like, and the new construction, reconstruction or extension of the house building can be realized only by construction activities with materials required; the 'auxiliary structure facilities' refer to water towers, bicycle sheds, pools and the like which are matched with the house building. The 'installation of lines, pipelines and equipment' refers to the installation activities of the lines, pipelines and equipment such as electricity, water supply and drainage, heating and ventilation, communication, intellectualization and elevators which are matched with the house building and the auxiliary facilities thereof. With the development of the construction industry, the technology is more and more perfect. However, certain dangerousness still exists in a building construction site, and corresponding warning equipment is indispensable.

However, the existing construction warning device is a simple warning board when being large in size, the warning effect is general, the warning mode is single, and improvement is needed.
