摘要:
An asymmetric bearing device automatically decreases, without the need for manual adjustment, an amount of friction exerted against rotation of a drum or other mechanism upon reversal of the direction of rotation of the drum.
摘要:
A pipe inspection system includes a cable storage drum and a housing configured to removably receive and rotatably support the cable storage drum. A push-cable with a plurality of conductors is stored in the cable storage drum. A camera head is connected to a distal end of the push-cable. A slip-ring assembly has first and second mating portions that when mated provide conductive paths between the plurality of conductors at a proximal end of the push-capable and a display device. The first portion of the slip-ring assembly is mounted on the housing and the second portion of the slip-ring assembly is mounted on the removable cable storage drum. The system connection cable joining the inspection system with a display unit is removable and may be replaced with cables compatible with various alternate image display systems.

Push-cables and associated apparatus and systems are disclosed. In one embodiment, a push-cable assembly for use with a pipe inspection system may include a push-cable element having a proximal end and a distal end, with a spring assembly having varying flexibility coupled to or near the distal end. The spring assembly may include an outer coiled spring having a proximal and a distal end, and an inner coiled spring nested at least partially within the outer coiled spring. A camera head and/or other elements such as a cutting or jetting apparatus may be coupled at or near the distal end.

A pipe inspection system may include a cable storage drum and a length of resilient flexible push-cable. An asymmetric bearing device supports the cable storage drum for rotation about the rotational axis in a pay-out direction and an opposite pay-in direction. In one embodiment, the asymmetric bearing device automatically decreases, without the for manual adjustment, an amount of friction exerted against rotation of the cable storage drum upon reversal of the direction of rotation of the cable storage drum from the pay-out direction to the pay-in direction.
