This is particularly difficult because the inspection vehicle may drive circumferentially, longitudinally and helically over the pipe or tank surface, meaning that the DCP must be realigned to ensure that the DCP is normal to the surface being inspected regardless of the inspection vehicle what is the location of

Embodiment Construction

[0027] figure 1 The external device 10 and the device (mechanism) 100 are generally shown, which is configured to be releasably coupled to the external device 10 and carry the probe sensor such that the sensor can reduce or deploy it for surface 11 (e.g., the surface of the pipe or tank). And when contact between at least a portion of the device 100 and the surface, the method is automatically made to the surface 11. As described herein, it should be understood that the outer device 10 does not necessarily have to contact the surface, but the one or more portions of the apparatus 100 can be in contact.

[0028] The outer device 10 can be in the form of a check car (e.g., the robot shown in this paper), a hand-held carrier, a robotic arm holder, a PIG or a scrappper for inspection within the conduit. In other words, according to a particular application, the device 100 can be coupled to any number of different devices. For example, device 100 can be coupled to a handheld carrier, ...

Abstract

The apparatus is configured to carry an instrument or probe and optionally deploy it against a surface, such as a metal pipe or storage tank. The apparatus may include a sensor probe for inspecting the integrity of a surface, and a first connector operably coupled to the sensor probe and configured according to the first A path (in a first direction / first degree of freedom) moves the sensor probe. An actuator may be operatively connected to the first link to move the first link, thereby moving the sensor probe along the first path. A second link is operably connected to the sensor probe and is configured to passively move the sensor probe according to a second degree of freedom to cause the sensor probe to move when at least a portion of the device contacts the surface. The probe becomes normal to the surface.

Description

Technical field [0001] The present invention relates to a device for supporting the instrument, such as a sensor (e.g., ultrasonic probe), and more particularly, the present invention relates to a device configured to carry a sensor such that the sensor can abut the surface (eg, tube wall) ) Reduce or deploy, and when the at least a portion of the device is in contact with the surface, it is automatically becoming at least substantially normal to the surface. Background technique [0002] The daily inspection of the equipment is essential to most industries to ensure security and optimization. For example, in the petroleum industry and related fields, liquids and gases and mixtures thereof via pipes are transported in large tanks. [0003] It is known in the industry that in order to maintain the integrity of the pipe, the storage tank, etc., the sensor device may be used to check such a surface. In particular, the checked vehicle can be used to travel across the surface of the t...
