Abstract: A 2-axis bracket assembly with smart linear actuators forms a mount for one or more sensors, and is controllable via a remote smart controller for the actuators, which may in turn be controlled by a remote PC and may control multiple 2-axis bracket assemblies. A two-axis gimballed support is mounted to an elevated structure, and a sensor is fixed thereto. The gimballed support includes a gimbal assembly, and a bracket to mount the assembly on a pole, a bracket assembly to hold the sensor. The gimbal assembly connects the pole bracket to the sensor bracket, permitting two-axis motion therebetween. Two smart linear actuators, one connecting the pole bracket to the gimbal assembly, and one connecting the sensor bracket to the gimbal assembly control the position of the sensor bracket and the sensor.

Abstract: A device is taught for making up or breaking out drill pipe sections. The device comprises one or more roller assemblies. Each roller assembly comprises a support movably attached to the roller assembly by an attachment means, one or more rollers supported on the support and one or more roller motors. The support can be raised and lowered by tightening or loosening the attachment means to allow access to the one or more rollers supported on the support. A mechanical roughneck system is further taught for making up or breaking out drill pipe section comprising the present device. A method is also provided for changing rollers in a spin wrench assembly.
