Abstract

The invention discloses a seven-channel rotating joint device. The seven-channel rotating joint device is installed on a main rotary table of a double-drum winding machine, the pipe wall of a rotating joint of the main rotary table is provided with an oil drain oil tube, a first winding drum lubricating oil pipe, a second winding drum lubricating oil pipe, a first winding drum expanding-collapsing oil inlet, a first winding drum expanding-collapsing oil outlet, a second winding drum expanding-collapsing oil inlet and a second winding drum expanding-collapsing oil outlet; an oil drain oil tube, a first winding drum lubricating oil pipe, a second winding drum lubricating oil pipe, a first winding drum expanding-collapsing oil inlet, a first winding drum expanding-collapsing oil outlet, a second winding drum expanding-collapsing oil inlet and a second winding drum expanding-collapsing oil outlet are correspondingly arranged in an inner cavity of a tube collecting shaft. The seven-channel rotating joint device is simple in structure, convenient to install and maintain and reliable in work.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, can satisfy the rotary oil supply of a double drum coiler, and relates to a seven-channel rotary joint device. Background technique [0002] In the double-drum coiler equipment, since the main turntable needs to rotate in each coiling cycle during operation, a rotary joint device is required to deliver hydraulic pressure and lubricating oil to the rotating main turntable. The rotary joint device on the existing equipment is generally set to five channels: the No. 1 reel expansion and contraction oil inlet and outlet, the No. 2 reel At the same time, a reversing solenoid valve is required on the expansion and contraction hydraulic passage of each reel to meet the switching of the expansion and contraction of the reel. Since the solenoid valve also rotates with the main turntable, it is necessary to A set of brush slip ring device is added to the equipment to realize the connection of...
