Embodiment Construction

[0015] The present invention relates to a system for creating a watertight seal around one or more flexible longitudinal members extending through a panel section. refer to figure 1 In the illustrated embodiment, sealing system 100 is configured to create a watertight seal around a plurality of various wires, cables, conduits, pipes, hoses and / or conduits 101 (also referred to herein as "flexible longitudinal members"), as described above. A flexible longitudinal member extends from the top drive motor housing 102 to a junction box 103 connected to the side of the motor housing 102 . Junction box 103 houses various electronic components (eg, bus bars and other electronic disconnects). Wiring, cables, conduit and / or tubing 101 extending from top drive motor housing 102 terminates at a bus bar or other electrical disconnect housed within junction box 103 .

[0016] refer to figure 2 In the illustrated embodiment, the sealing system 100 is attached to the wall 104 of the junc...

Abstract

A system configured to seal at least one flexible longitudinal member is provided. In one embodiment, the system includes a sealing member having at first set of apertures, a second set of apertures, and inner and outer interface surfaces. The system also includes a clamping member having a first set of apertures and an interface surface. The first set of apertures in the clamping member is configured to align with the first set of apertures in the sealing member. The first sets of apertures are configured to receive the at least one flexible longitudinal member. The interface surface of the clamping member is configured to abut the inner interface surface of the sealing member. The system also includes at least one threaded blind bore in the interface surface of the clamping member, and at least one fastener configured to draw the clamping member into engagement with the sealing member.

Description

technical field [0001] The present invention relates to sealing systems and, more particularly, to a system for sealing wiring, pipes and conduits passing through wall members. Background technique [0002] The top drive motor (ie, the drilling motor used to drive the drill string and the drill bit connected to the drill string to form the borehole) is typically air cooled by a blower. In severe weather conditions, rainwater can flow into the blower, which in turn can enter the junction box that houses various electronic components (for example, bus bars and other electronic disconnects). One potential leak path for top drive motors is along the various wiring, cables, pipes and tubes that run from the motor to the top drive's junction box (for example, water may tend to penetration of cables, pipes and pipes). The presence of water within the junction box may damage various electronic components housed within the junction box and pose a risk of electric shock to workers. ...
