Cable handling devices, methods, and systems for securing and deploying or retracting one or more cables or hoses into or out of a pipe or cavity allowing inspection of the pipe or cavity. In an exemplary embodiment, a hand-held device with a housing for at least partially enclosing one or more cables or hoses, at least one coupling mechanism integrally attached to the housing, and a coupling control for coupling and decoupling the one or more cables or hoses is provided. The cable handling device and the one or more cables or hoses can be coupled and moved together, or decoupled enabling the cable handling device and the one or more cables or hoses to move independently of each other. One or more of the cables may be connected to a camera for facilitating inspection of a pipe or cavity.

Disclosed is a drive wheel set, comprising a common shaft and at least two external rotor motors installed on the common shaft. External rotors of the external rotor motors form drive wheels of the drive wheel set. Also disclosed are a vertical-type wire storage frame, a swing-type wire storage frame, a guide wheel frame, a traction mechanism and a multi-path conveying mechanism using the drive wheel set. The drive wheel set is small in size, occupies less space, and is suitable for a situation where a plurality of motors need to be driven but sufficient space is lacking.

A system for adjusting a path of a wire includes a precast pulley assembly having at least one precast pulley having at least first and second positions. The at least one precast pulley may be adjustable from the first position to the second position without a user touching the at least one precast pulley. A path of a wire is adjusted when disposed around the at least one precast pulley when it is in the second position instead of in the first position. In one embodiment, the precast pulley assembly includes first and second precast pulleys disposed in an adjacent relationship with respect to one another, wherein a wire can selectively pass over one or both of the first and second precast pulleys.

Disclosed is a moving device. A moving device for moving a tubular member according to an aspect of the present disclosure may include a housing through which the tubular member passes, a first roller and a second roller arranged to face both sides of the tubular member inside the housing and having outer circumferential surfaces that presses the tubular member, an actuator that provides a driving force for rotating the first roller, a sensor that measures a movement amount of the tubular member, and a controller that controls the actuator on the basis of the movement amount of the tubular member, wherein, when the first roller rotates, the tubular member between the first roller and the second roller moves by a frictional force.

A cable retractor includes a housing. A motorized drive section within the housing urges at least a segment of cable past the drive section. A chamber within the housing holds at least another segment of the cable that is stored freely without a specific arrangement of the cable. The motorized drive section urges the cable in a first direction to draw the at least another segment from the chamber, then past the motorized drive section, and then through an external opening in the housing to outside. The motorized drive urges the cable in a second, opposing direction to draw the another segment through the external opening in the housing from outside, then past the motorized drive section, and then into the chamber, the another segment being urged freely into the chamber without a specific arrangement of the cable in the chamber.

A cured-in-place-pipe (CIPP) end cap internal roller apparatus is disclosed. The apparatus can include a housing having an opening, wherein the housing can further include an interior space. In addition, the apparatus can include a roller assembly, wherein the roller assembly is at least partially disposed within the interior space of the housing and at least partially disposed through the opening of the housing. Further, the apparatus may include a grommet seal coupled to an upper region or side region of the housing, wherein the seal includes an opening. Further, the opening of the grommet seal may be at least partially aligned with the roller assembly. The roller assembly may further include a plurality of rollers or rotatable members secured between a first bracket and a second bracket, wherein the first bracket and second bracket each include an at least partial arcuate configuration.
