Abstract

The invention relates to large-size thin-wall structure workpiece turnover devices used in group and a working method. The large-size thin-wall structure workpiece turnover devices comprise the multiple moving turnover devices and the multiple fixing turnover devices, and the multiple moving turnover devices and the multiple fixing turnover devices are arranged in a staggered mode; each moving turnover device comprises a moving machine body, the moving machine body is slidably connected with a guide rail, the guide rail is connected with a base through an adjusting mechanism, the moving machine body is connected with a first driving mechanism, the first driving mechanism drives the moving machine body to slide along the guide rail, the moving machine body is rotationally connected with a first workbench, and the first workbench is connected with a second driving mechanism and driven by the second driving mechanism to rotate; and each fixing turnover device comprises a fixing machine body, the fixing machine body is rotationally connected with a second workbench, and the second workbench is connected with a third driving mechanism and driven by the third driving mechanism to rotate.The quantity of accessory workpieces adopted by the turnover devices is small, manpower and material resources are saved, and the safety is good.

Description

technical field [0001] The invention relates to the technical field of workpiece turning equipment, in particular to a large thin-walled workpiece turning device and working method used in groups. Background technique [0002] The SC component of the shielded building of the pressurized water reactor nuclear power plant is a typical large-scale thin-walled structure with complex structure and poor rigidity. During processing and manufacturing, it needs to present a variety of stations to meet welding and other requirements. The designed turning equipment requires accurate positioning and reliable clamping. Easy to flip. [0003] At present, the movement and flipping of the SC components in the shielding plant are completed with the aid of driving and hoisting equipment. Due to the large size and mass of the SC components in the shielding plant, the overall rigidity is small, there are many internal accessories and the distribution is irregular, the position of the center of ...

Problems solved by technology

[0003] At present, the movement and flipping of the SC components in the shielding plant are completed with the aid of driving and hoisting equipment. Due to the large size and mass of the SC components in the shielding plant, the overall rigidity is small, there are many internal accessories and the distribution is irregular, the position of the center of gravity is not easy to determine, and the lifting point Limited, it is easy to cause deformation of the SC components of the shielding plant, which affects the subsequent assembly of the SC components of the shielding plant; for the SC components of the shielding plant that are not completely welded, local reinforcement is required, which increases the amount of engineering and product costs; in addition, the center of gravity of the SC components of the semi-finished shielding plant The center of gravity of the SC components in the shielding plant is inconsistent. If the same set of lifting lugs is used, the risk of hoisting will increase. Otherwise, the number of lifting lugs needs to be increased and the amount of work will be increased. Different SC components in the shielding plant need to design suitable lifting beams and flip tooling in a targeted manner. Appropriate temporary supports should be set up for the SC components of the shielding plant to prevent the module from deforming during hoisting and flipping. During the hoisting process, the number of lifting lugs is large, and the additional workload is large. Some modules require multiple cranes to coordinate operations, and synchronous operation is difficult.
