Detailed Description

With reference to the drawings, the present embodiment provides a pipeline connecting device for a rotating component of a pipe slice assembling machine, which includes a fixing ring 2, a slewing bearing 11 and a rotating ring 3, wherein the slewing bearing 11 is a standard component, the rotating ring 3 is connected with an inner ring of the slewing bearing 11, the fixing ring 2 is connected with an outer ring of the slewing bearing 11, the slewing bearing 11 is driven by an externally connected motor, the inner ring rotates during operation to drive the rotating ring 3 to rotate, the outer ring does not rotate, so that the fixing ring 2 does not rotate, and two support rods 4 are fixedly connected to the rotating ring 3 for connecting pipelines.

The cooperation is rotatory ring 3 and is provided with assembly pulley 1, and assembly pulley 1 includes a plurality of pulleys 8, even axle 9, interval baffle 7, direction baffle 6 and roll baffle 5, and even axle 9 is in the same place whole pulley 8 cluster, separates through the interval baffle between the adjacent pulley 8, makes every pulley 8 contactless, does not influence each other during the rotation.

The guide baffle 6 is two, set up respectively in the outside that is located the pulley 8 at both ends, roll baffle 5 is two, set up respectively in the outside of two guide baffle 6, two guide baffle 6 respectively with the track of solid fixed ring 2 in along the contact, two roll baffle 5 respectively with rotatory ring 3 cooperation, make rotatory ring 3 can drive roll baffle 5 and rotate, roll baffle 5, guide baffle 6 and even axle 9 bolt simultaneously, still accompany spacer ring 10 between guide baffle 6 and the pulley 8. The wire baffle prevents that the assembly pulley 1 breaks away from the swivel ring when rotating, and roll baffle 5 rolls on the side ring edge of rotatory ring 3, and the spacer ring 10 prevents that during operation oil from congealing on pulley 8, makes the rotation of pulley 8 receive the influence.

The fixed ring 2 is connected with a plurality of pipelines 12, one end of each pipeline 12 is fixed on the fixed ring 2, each pipeline 12 bypasses one pulley 8 in the pulley block 1, and the other end is bypassed and connected with one support rod 4, so that each pulley 8 can be regarded as a movable pulley 8 structure, when the rotating ring 3 rotates 220 degrees as required, the pulley 8 group 1 can roll 110 degrees on the track of the fixed ring 2, and the pipelines 12 on the pulley block 1 realize the power supply of the actuating elements on the rotating ring 3.

The pipelines 12 are evenly distributed and wound on the pulley block 1, so that the number of the pipelines 12 extending to the two sides of the pulley block 1 is as close as possible, and the stability of the whole body in working is ensured. For example, if the pulley block 1 is provided with six pulleys 8, three pipelines 12 are respectively arranged on two sides of the pulley block 1 and are wound on the pulley block 1 alternately, and each support rod 4 is connected with three pipelines 12; if five pulleys 8 are arranged on the pulley block 1, three pipelines 12 are arranged on one side of the pulley block 1, two pipelines 12 are arranged on the other side of the pulley block 1, the three pipelines 12 are alternately wound on the pulley block 1, the supporting rods 4 on the sides of the three pipelines 12 are connected with the three pipelines 12, and the supporting rods 4 on the sides of the two pipelines 12 are connected with the two pipelines 12.

The entire pipe 12 tightens the pulley block 1 as a whole onto the rotating ring 3 and makes the pulley block 1 roll sufficiently along the edge of the rotating ring 3.

When the oil-gas separator works, oil or signals are connected from one end of the pipeline 12 (an oil pipe or a signal wire) fixed on the fixed ring 2 and are output from the supporting rod 4 on the rotating ring 3, so that other external rotating motion executing elements fixed on the rotating ring 3 can be directly connected with various pipelines 12, the structure is simple, the installation and the maintenance are convenient, and manpower and material resources are saved.
