Embodiment Construction

[0025] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] Such as figure 1 As shown, it is a schematic structural view of the automatic safety uncoupling mechanism provided by the present invention; this mechanism is suitable for the assembly process of different reactor nuclear fuel element production line components. The uncoupling device 3 rotatably arranged on the slide plate 2, the selection device 4 and the stretching device 5 arranged on the slide plate 2, and the air control system controlling the operation of the entire unhook mechanism. Among them, the number of tie rod assembly 1 is controlled by the selection device; the slide plate drives the tie rod assembly to move horizontally under the drive of the power system; the stretching device controls the head claw of the tie rod assembly to clamp the fuel rod and pull it into the grid of the fuel assembly; decou...

Abstract

The invention relates to an automatic safety decoupling mechanism applied to nuclear fuel element assembly processes. The automatic safety decoupling mechanism comprises a pull rod component and a slide carriage, the pull rod component comprises a pull rod and an option key fixed on the pull rod, and a slot is arranged in the option key; the slide carriage is arranged above the pull rod component, a driving mechanism driving the slide carriage to move linearly is arranged on the lower surface of the slide carriage, a decoupling device is arranged on the slide carriage and comprises a pulling plate which is rotatably connected on the slide carriage, a protrusion is arranged on the lower surface of the pulling plate, and the protrusion is clamped in the slot of the option key; a support plate is arranged at the tail end of the slide carriage, and a tension spring is arranged between the support and the pulling plate. By the arrangement, the pull rod component can be automatically safely assuredly decoupled when bumping with a grillwork during the nuclear fuel element assembly processes, so that damage to the grillwork can be avoided; demands on continuous, reliable and automatic production can be met; the automatic safety decoupling mechanism is compact in structure, high in integration level and reliable in action.

Description

technical field [0001] The invention belongs to the field of assembly of nuclear fuel assemblies, and in particular relates to an automatic safety decoupling mechanism, which is suitable for automatic assembly of fuel rod assemblies in the assembly process of assemblies of nuclear fuel element production lines. Background technique [0002] With the development of the nuclear power industry since the "Twelfth Five-Year Plan", my country's demand for nuclear fuel element production capacity is also increasing. In order to rapidly increase my country's nuclear fuel element production capacity and production efficiency, and to improve the level of nuclear power technology, through introduction and independent innovation, the technical level of my country's nuclear fuel element production lines under construction and to be newly built during the "Twelfth Five-Year Plan" period has improved to varying degrees compared with the past. improve. However, in the production line of nuc...
