Suspended hanging basket crane for high-altitude outer wall operation based on nuclear reactor

Abstract

The invention discloses a suspended hanging basket crane for high-altitude outer wall operation based on a nuclear reactor. The suspended hanging basket crane comprises a movable frame mechanism, a suspension driving mechanism and a hanging basket, wherein the movable frame mechanism comprises two main beams; a counterweight device is arranged at the left ends of the two main beams; the left endsof the two main beams are connected and fixed through a first connecting beam; the right ends of the two main beams are connected and fixed through a second connecting beam and a third connecting beam; a platform is mounted between the second connecting beam and the third connecting beam; crane wheels are mounted at the lower ends of the two sides of the two main beams; two tracks are arranged ona dome of the reactor; the crane wheels are arranged on the tracks; the suspension driving mechanism is mounted at the right ends of the two main beams; a rope at the lower end of the suspension driving mechanism is connected with the hanging basket; and the hanging basket can move left and right on the main beams under the driving of the suspension driving mechanism. According to the suspended hanging basket crane disclosed by the invention, the movable frame mechanism is matched with the suspension driving mechanism, so that a person can reach any position of an outer wall to operate by taking the hanging basket, and meanwhile, the outer wall of the nuclear reactor cannot be damaged.

Description

technical field [0001] The invention belongs to the technical field of civil engineering maintenance and construction, and in particular relates to a suspension basket crane for high-altitude outer wall operations based on nuclear reactors. Background technique [0002] At present, according to the traditional construction method, scaffolding is generally used for maintenance, installation of facilities on the outer wall or maintenance of the outer wall of the nuclear power plant reactor building in operation. This method has the following problems: [0003] 1. There are many facilities and operating equipment installed around and below the reactor building, and the erection of scaffolding will bring the risk of damage to the equipment. [0004] 2. The height of the reactor building is 53m. Since the outer wall does not allow drilling to install expansion bolts to fix the scaffolding (this is the nuclear safety management regulation of the power station), it brings difficult...

AI Technical Summary

Problems solved by technology

[0003] 1. There are many facilities and operating equipment installed around and below the reactor building, and the erection of scaffolding will bring the risk of damage to the equipment

[0004] 2. The height of the reactor building is 53m. Because the outer wall does not allow drilling to install expansion bolts to fix the scaffolding (this is the nuclear safety management regulation of the power station), it brings difficulties to the reinforcement of the scaffolding

[0005] 3. Part of the plant below the reactor plant has a light steel structure profiled tile roof, and scaffolding is not allowed on it
