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 a screwing and clamping integration device for a screw. The device comprises a driving mechanism, a connection mechanism and an execution mechanism. The driving mechanism is used for driving rotation of the overall device. The connection mechanism is connected with the driving mechanism and used for transmitting the torque generated by the driving mechanism and lengtheningthe length of the overall device. The execution mechanism is connected with the end, away from the driving mechanism, of the connection mechanism and used for clamping the screw and driving the screwto rotate. The screwing and clamping integration device for the screw has a guide function in deep water and under an environment with irradiation, the operation time of centering the screw is shortened, the efficiency is high, the screw is safe and reliable to clamp and carry, the guarantee is provided for safe and smooth replacement of a control rod guide cylinder, by adopting part modularization design, the device can be universally used with other tools, and the tool number is lowered.

Description

Technical field [0001] The invention relates to the technical field of clamping devices, in particular to an integrated screw screw clamping device. Background technique [0002] In the construction pool of a pressurized water reactor nuclear power plant, the replacement of the control rod guide tube requires the removal of the bolts and the removal of the bolts to the designated position to avoid the bolts being left in the reactor and causing safety accidents. At present, the bolts in related technologies The grasping device has the following problems: (1) The length of the device is generally fixed and cannot be extended; (2) The clamping bolts are unreliable in a deep water environment, and there is a risk of losing the bolts during transportation; (3) Device pair The middle bolt is inconvenient and inefficient; (4) It cannot be transported while holding the bolt. [0003] Therefore, there is a need for a device that can simultaneously realize bolt clamping and transportation ...
