When a wheel clamp is used, width of a wheel is detected first, a first servo motor drives a lead screw to rotate, a supporting block and a lifting plate are automatically adjusted to appropriate heights via a nut, a manipulator puts the wheel onto end face blocks, air-tight devices are pressed down, an oil cylinder drives a chuck so that clamping jaws expand the central hole of the wheel, meanwhile, four air cylinders drive clamping blocks to compact outer side of the wheel, and the wheel is completely positioned; at this moment, a bolt hole of the wheel can be drilled; after machining, second servo motor drives right shaft, right lug plate and a turnover part to rotate certain angles via second decelerator; high pressure oil is introduced into cavities between ipsilateral expansion sleeves and end covers, and left and right shafts are separately locked by ipsilateral expansion sleeves.

The present disclosure relates to a drilling device for machining tubes in tube sheets of heat exchangers in a radioactive environment. A retaining plate is clampable in the tubes with at least two retaining fingers on a first side and a first drive, which drives a tool shaft, is arranged on a second side. A tool chuck on a first end side of the tool shaft is connected detachably to the latter, wherein a forward feed of the tool shaft is brought about by a feed device. In addition, the tool chuck is unlockable from the tool shaft by way of an unlocking instrument and the unlocking instrument is controllable by a remote-control device.

A method and apparatus for manufacturing an aircraft structure. A drivable support may be driven from a first location to a second location to bring the drivable support together with at least one other drivable support to form a drivable support system. A structure may be held in a desired position using the drivable support system.

A device for opening a connection to a lined pipe is disclosed. The device has a body that includes a front end and a rear end and being rotatable about a rotation axis. The device also has a drill head that has multiple cutters for puncturing and enlarging a hole in a liner, and multiple side cutters have at least one cutting edge parallel to the rotation axis. A safety ring is disposed on the body between the drill head and the side cutters. The safety ring has a circular periphery extending beyond the drill head and the side cutters in a direction perpendicular to the rotation axis.

A method and apparatus for tapping into a pressurized multiple strings of coaxially situated tubulars for wells and/or platforms which have overturned wherein the tapping occurs underwater via a diver or remotely operated vehicle. The assembly includes a tapping tool connectable to the tubular via a saddle connection and an adjustable tapping clamp with adjustable support/locking feet, compression plate with view ports, and angularly adjustable hot tapping system, along with a drill/saw system.

The Overhead Drill and Anchor Press is a single mobile mechanism designed for installation of anchors into a construction surface which is overhead and out of reach of the installer. The overhead drill and anchor press may include a mast, a turret assembly, a controller, and at least one drill. The overhead drill and anchor press can execute the anchor installation sequence automatically or manually with a controller by moving the drill position to drill the hole and set the anchor. The controller may be equipped with a digital display of the turret mounted camera for monitoring the process from the ground. The entire assembly may be manually pushed between target.
