BOLT AND NUT DISASSEMBLING APPARATUS |
摘要 |
A apparatus for disassembling a threaded bolt and nut assembly wherein the bolt is initially extended through an opening provided on a structure and being secured thereto with the nut axially mounted on a threaded rod of the bolt. The apparatus comprises a tool body, a nut gripping element such as a socket mounted for rotation on a working portion of the tool body, the socket being provided with a bore axially extending theretrough. The apparatus further comprises a rotary actuator mounted on the tool body and operatively coupled to the socket for imparting torque to the mounted nut in a direction allowing release of the nut from the secured bolt. The apparatus also comprises a pushing device such as a pneumatic power hammer mounted on the tool body and provided with an elongated push member having a working end being axially displaceable within the bore, and a linear actuator mounted on the tool body and operatively coupled to the hammer for selectively displacing the push member between a retracted position allowing the release of the mounted nut and an extended position where the bolt is at least partially withdrawn from sai d opening upon thrust of the working end of the push member. A pneumatic control system is provided for controlling the rotary actuator and the linea r actuator. The apparatuscan be provided with a base for supporting the tool body and a holder connecting the base to the tool body while allowing transversal displacement thereof on the holder. A first embodiment uses a base provided with a rotary arm, while a second embodiment uses a base provided with a displaceable carrier mounted on a rail.
