Problems solved by technology

[0002] In the construction pool of the pressurized water reactor nuclear power plant, the replacement of the control rod guide cylinder needs to dismantle the bolts and move the dismantled bolts to the designated position, so as to avoid the bolts left in the reactor and cause safety accidents. At present, the bolts in the related technology The grasping device has the following problems: (1) the length of the device is generally fixed and cannot be extended; (2) the clamping bolt is unreliable in a deep water environment, and there is a risk of the bolt being lost during transportation; (3) the device is The middle bolt is inconvenient and inefficient; (4) It cannot be transported under the state of clamping the bolt

Abstract

The invention relates to an integrated screw screw clamping device, which includes a driving mechanism for driving the rotation of the whole device; a connecting mechanism connected with the driving mechanism for transmitting the torque generated by the driving mechanism and extending the whole The length of the device; and the actuator, which is connected to the end of the connecting mechanism away from the driving mechanism, and is used for clamping and driving the screw to rotate. The screw twisting and clamping integrated device of the present invention has a guiding function in deep water and irradiated environments, shortens the operation time of the centering screw, has high efficiency, and is safe and reliable for clamping and transporting the screw. It is a control rod guide cylinder. The safe and smooth replacement is guaranteed, and the modular design of the components is adopted, which can be used in common with other tools, reducing the number of tools.

Description

technical field [0001] The invention relates to the technical field of clamping devices, in particular to an integrated screw screwing and clamping device. Background technique [0002] In the construction pool of the pressurized water reactor nuclear power plant, the replacement of the control rod guide cylinder needs to dismantle the bolts and move the dismantled bolts to the designated position to avoid the bolts remaining in the reactor and causing safety accidents. At present, the bolts in the related technology The grasping device has the following problems: (1) the length of the device is generally fixed and cannot be extended; (2) the clamping bolt is unreliable in a deep water environment, and there is a risk of the bolt being lost during handling; (3) the device is The middle bolt is inconvenient and inefficient; (4) it cannot be carried under the state of clamping the bolt. [0003] Therefore, there is a need for a device that can simultaneously realize bolt clam...
