Abstract
Releasable spider-type clamping apparatus for clamping to the end of a pipe comprises a system including a normal industrial line connection between a supply and control unit and the spider and a controllable operating device on the spider itself for operating and adjusting the clamp members, at least for the purpose of releasing them in the event the normal industrial line connection fails, the operating device comprising a pressure medium system with at least one pressure medium storage device and a wireless remote control and/or manual system.
Claims6
Apparatus for releasable clamping to the end of a pipe, comprising:
- a support structure;
- clamping members movably mounted on said support structure;
- adjusting means operable by a pressure medium, for moving said clamping means between a clamping position and a releasing position;
- pressure medium supply means;
- control means for controlling pressure medium from said supply means;
- connecting means for connecting said adjusting means to said pressure medium supply means and control means via pressure medium lines;
- and
- controllable opening means mounted on the support structure for operating said adjusting means for moving said clamping members to at least said releasing position comprising
- a pressure medium system including at least one pressure medium storage means,
- conduit means for connecting said pressure medium system to said adjusting means,
- control valve means operatively connected to said conduit means for controlling pressure medium between said pressure medium system and said adjusting means, said control valve means having a stop position for disconnecting said adjusting means from said pressure medium system and at least one operating position for operating said adjusting means by said pressure medium system for moving said clamping members to either one of said clamping and releasing positions, and
- a wireless remote control system for operating said control valve means.
