Abstract
An apparatus for facilitating the connection of pipes comprises a rotary (4) and a stator (5), the rotary comprising at least one hydraulically actuated jaw (24,25,26), and a pump (58) arranged on the rotary (4) for pumping hydraulic fluid for actuation of the or each jaw (24,25,26), the stator comprising a motor (55) arranged on the stator (5), so that rotational energy can be transferred from the motor to the pump in an operational configuration.
Claims19
An apparatus for facilitating the connection of pipes and comprising a rotary and a stator, the rotary comprising at least one hydraulically actuated jaw, and a pump arranged on the rotary for pumping hydraulic fluid for actuation of the at least one jaw, the stator comprising a motor arranged on the stator, so that rotational energy can be transferred from the motor to the pump in an operational configuration, characterized in that the motor comprises driving means and the pump comprises pump driving means, the driving means and pump driving means being mechanically engageable.
A method for facilitating the connection of pipes, comprising mechanically engaging a motor attached to a stator with a pump attached to a rotor and transferring rotational energy from the motor to the pump, enabling the pump to drive hydraulic fluid to actuate at least one jaw.
An apparatus for facilitating the connection of pipes, comprising:
- a rotary comprising at least one hydraulically actuated jaw;
- a stator;
- a motor arranged on the stator and comprising a driving member, wherein the motor is actutatable between a first position and a second position;
- and
- a pump arranged on the rotary for pumping hydraulic fluid for actuation of the at least one jaw and comprising a driving member, wherein the motor driving member and the pump driving member are engageable, when the motor is in the second position, for transferring energy from the motor to the pump.
