Description
Technical Field
[0001] The utility model relates to the technical field of building engineering construction, in particular to a safety device and a safety system for the construction and maintenance of building facades. Background Art
[0002] With the acceleration of urbanization, buildings play an increasingly important role in various cities, resulting in more and more high-rise buildings in cities. The construction of high-rise buildings has increased a large number of opportunities for high-altitude operations. For example, the construction process of high-rise buildings or the daily inspection, maintenance, and cleaning of high-rise buildings after construction requires personnel to perform high-altitude operations. Common high-altitude operations are to send personnel from the top to the working position through a hanging basket. Due to the certain volume of the hanging basket, it can only be used in large-area working positions, such as exterior wall glass, and the hanging basket cannot reach the narrow position, resulting in the inability to construct or maintain in place; or the rope is fixed by a certain fixed structure to send the operator to the working position, but the need to fix the fixed structure during use will cause certain damage to the building wall, or the embedded fixed structure cannot slide left and right. If it slides left and right, it may cause the rope to wear and put the construction personnel in an unsafe situation. Therefore, a safety device for building facade construction and maintenance that can operate in a small space and slide left and right within a certain distance is proposed. Utility Model Content
