The nuclear power plant ring crane (referred to as the nuclear ring crane) is a special bridge crane installed on the circular track above the nuclear island reactor building of the nuclear power plant, serving the entire construction, operation, and retirement cycle of the nuclear power plant. It is one of the important equipment of the nuclear power plant. The safe operation of nuclear ring cranes is crucial for ensuring the safety and production of nuclear power plants. The frequent occurrence of earthquakes is an important factor affecting the safety of nuclear ring cranes. Therefore, in the design specifications, it is required that nuclear ring cranes should have good seismic performance. However, with the continuous development of nuclear power technology, traditional design methods for nuclear ring cranes are no longer able to meet seismic requirements, so new design methods are needed to improve the seismic performance of nuclear ring cranes. At present, a simple and effective method is to use shock-absorbing devices to reduce the seismic load on the nuclear ring crane structure, thereby improving the seismic performance of the nuclear ring crane.At present, there is relatively little research on using shock absorption devices to improve seismic performance of nuclear ring cranes, especially for vertical shock absorption devices, which are almost non-existent. Based on the design characteristics of the nuclear ring crane structure, this article designs a new type of shock-absorbing device to improve the seismic performance of the nuclear ring crane without affecting its normal operation.

This machine is a key equipment in the carbon block warehouse of the anode electrolysis aluminum plant. It can transport raw and cooked anode carbon blocks and transport them to designated locations through a chain conveyor. The machine mainly consists of electrical system, bridge, crane operating mechanism, lifting mechanism, guiding device, combination clamp device, electric hoist, single carbon block clamp, operating system, and other parts.The main functions of this machine are:Firstly, 21 anode carbon blocks are clamped by a combination clamp device, and the carbon blocks are transported to a designated location and stacked into piles through a lifting mechanism and operating mechanism, with a height of up to 8 layers.Secondly, the electric hoist is connected to the lifting ear of a single automatic clamp through a hook, assisting the combination clamp in gripping carbon blocks and lifting debris. The main feature of this machine is that the carbon blocks are automatically clamped and placed, replacing the traditional pneumatic clamping method. Each vehicle can save 400000 yuan in cost.This machine has been used in major carbon factories across the country, meeting the production requirements of users and receiving high praise from users. It is also one of the leading products of the company and can replace imported products, with a broad market.
