Container transfer operation platform for nuclear industry

Abstract

The invention relates to a transferring operational platform for containers used in the nuclear industry. The operational platform comprises a transferring robot, an open-close gripper and a container. The open-close gripper is arranged on the transferring robot and is matched with the container. The container comprises a container body and a container cover. The container cover comprises a cover body and a chucking mechanism. The chucking mechanism includes a rotary shaft, an elevating nut, a jaw, a retainer lever, a limit lever and a force applying plate. The open-close gripper includes a gripper body, a translational mechanism, a rotary mechanism and a gripper mechanism. A rotary operation member cooperates with an operation end of the rotary shaft; the gripper member cooperates with the container body and the container cover, and a positioning member is matched with the force applying plate. The automatic and reliable transferring operational platform is capable of satisfying the actual demands of nuclear industry, and possessing a certain degree of adjustability in the operating state. Furthermore, by using the transferring operational platform, accidents can be avoided in case of emergency and the danger can be precluded through manual adjustment.

Description

technical field [0001] The invention relates to an automatic transfer device, in particular to a container transfer operation platform for nuclear industry. Background technique [0002] The working environment of the nuclear industry will be accompanied by a large number of pollutants, which will cause great damage to the external environment or the human body. Therefore, the working environment of the nuclear industry should be carried out in a fully enclosed site as much as possible, and the requirements for working equipment are highly demanding. Automation and reliability to help workers avoid the threat of pollutants. In addition, the working equipment used in the nuclear industry also needs to be adjustable to meet the working needs of different requirements. [0003] Existing automatic opening and closing grippers, such as the Chinese patent announcement CN205294778U discloses an automatic opening and closing cover platform, which achieves the purpose of opening and ...

AI Technical Summary

Problems solved by technology

[0003] Existing automatic opening and closing grippers, such as the Chinese patent announcement CN205294778U discloses an automatic opening and closing cover platform, which achieves the purpose of opening and closing the container through the cooperation of the gripper, the three-jaw chuck and the container, but this technology is not widely used in the nuclear industry. There are the following problems in the application: 1. The tightness between the cover and the container is achieved by rotating the container during the opening and closing process, which will cause the material to move with the container; 2. The connection between the cover and the container by screwing the cap cannot provide sufficient connection strength. , unable to support the high-pressure environment required for the internal work of the container; 3. The connection between the cover and the container is not adjustable, and the closing tightness between the cover and the container cannot be quickly and flexibly adjusted according to the working situation; 4. It does not meet the sudden requirements. Safety requirements in emergency situations, if the gripper does not have a self-locking function when the power is cut off, the container will fall during the transfer process, causing serious safety accidents

[0004] X-axis and Z-axis bidirectional motion robots are also relatively common in the machinery manufacturing industry. For example, Chinese patent announcement CN204603115U discloses a sheet metal stamping automatic loading and unloading robot. However, there are also problems in the application of this technology in the nuclear industry: 1. It does not meet the safety requirements in emergencies. For example, the robot does not have a self-locking function when the power is turned off, which will cause the container to fall during the transfer process. 2. When the power is cut off or the motor is damaged, it is impossible to eliminate the danger through external manual operation; 3. It is difficult to maintain, because the motor and the matching equipment such as the reducer are set inside the equipment, and maintenance must be done. access to the working area of ​​the robot, which is inconvenient in the nuclear industry
