each brush 13 is attached to only one conductive layer 121. According to the present invention, since each annular conductive layer 121 is electrically connected to only one conductive pillar 122, separate power transmission of different kinds is achieved.
Further, in the present invention, a specific implementation method of electrically connecting each annular conductive layer 121 with only one conductive pillar 122 is not limited, and those skilled in the art can implement the method according to actual needs, for example, an insulating sleeve is sleeved outside the conductive pillar 122, so that when the conductive pillar 122 is in contact with another conductive layer 121 that does not need to be electrically connected, electrical conduction is not generated.
According to a preferred embodiment of the present invention, a pin hole is provided on the inner side of the conductive layer 121 and at a position corresponding to the conductive rotating shaft 12, so as to fix the two by a pin.
Although the conductive layer 121 and the conductive shaft 12 may be fixed together by the conductive pillar 122, a large radial force may be generated due to continuous friction between the conductive layer and the brush, and the radial force may be finally applied to the connection position of the conductive pillar 122 and the conductive layer 121, so that the connection strength between the conductive pillar 122 and the conductive layer 121 is reduced, and the service life of the device is reduced. In the present invention, the conductive layer 121 and the conductive rotating shaft 12 are fixed by setting the pin, so that the damage of the radial force to the connection position of the conductive post 122 and the conductive layer 121 can be greatly reduced.
According to the invention, the welding equipment with the slewing device is used for welding the steam generator in the nuclear power field, and the steam generator has extremely high requirements on welding quality, so that the welding equipment is required not to have large jitter during rotary welding, namely, the rotation of the conductive sliding ring needs to be smooth, and the phenomena of rotation blocking, shaking of the conductive rotating shaft and the like cannot occur.
In a preferred embodiment, each layer of brushes 13 has four brushes 13, and the four brushes 13 are uniformly distributed in the circumferential direction of the conductive layer 121, so that the conductive layer 121 is uniformly stressed, and the conductive rotating shaft 12 is prevented from shaking due to the eccentric wear of the conductive layer 121. According to a preferred embodiment of the present invention, as shown in fig. 3, the brush 13 includes a brush holder 132 fixedly coupled to the stationary housing 11, and a brush core 131 installed inside the brush holder 132,
the brush holder 132 is a box body,
one end of the brush core 131 is an arc surface, so that the brush core can be attached to the side surface of the annular conductive layer 121.
In order to improve the smooth performance of the rotation of the conductive slip ring and reduce the problems of rotation seizure and rotation jitter, in a preferred embodiment, a plurality of columnar conductive rollers 15 are further disposed between the brush 13 and the conductive layer 121, as shown in fig. 5.
In practical use, the brush core 131 is directly contacted with the annular conductive layer 121, after long-term use, the brush core 131 is prone to eccentric wear, the annular conductive layer 121 is prone to uneven stress, the annular conductive layer 121 is prone to abnormal wear, and the problems of rotation blocking and rotation shaking are prone to occurring. In the invention, the sliding friction between the brush 13 and the conductive layer 121 is changed into rolling friction by arranging the columnar conductive roller 15, so that the abrasion rate is greatly reduced, and the smooth performance of the rotation of the conductive slip ring is improved.
In one embodiment, the upper and lower end portions and the side portions of the conductive roller 15 are provided with ribs 151, and the ribs 151 are fixed to the brush 13 for fixing the conductive roller 15 to the brush 13.
In a more preferred embodiment, as shown in fig. 6, the conductive roller 15 is uniformly arranged on the circumferential direction of the annular conductive layer 121, ribs 151 are arranged on the upper and lower end portions of the conductive roller 15, and the conductive roller 15 is fixed on the annular conductive layer 121 through the ribs 151. Because the conductive roller 15 is no longer fixed with one of the brushes 13, that is, the plurality of brushes 13 share all the conductive rollers 15, the problem of shaking caused by the fact that one conductive roller 15 is abraded greatly when the conductive slip ring rotates can be avoided. In a preferred embodiment, a spring is provided between brush holder 132 and brush core 131, and brush core 131 is pressed by the spring to press brush core 131 against conductive layer 121.
In a preferred embodiment, the other end of the brush core 131 is rectangular, the brush holder 132 is a square box, so that the brush holder 132 can be sleeved on the brush core 131, and the brush holder 132 of the square box has a guiding function, so that the brush core 131 can only move in the radial direction of the annular conductive layer 121, thereby avoiding the brush core 131 from shaking and reducing the eccentric wear probability of the brush core 131.
Further, the brush holder 132 is a conductor, and a cable connected to the electric cabinet is fixed to the brush holder 132.
The cable is fixed on the brush holder 132, and compared with the direct connection of the cable and the brush core 131, the phenomenon that the power supply is unstable due to the fact that the brush core 131 is not tightly combined with the conductive layer 121 or the conductive roller 15 due to the shaking of the cable is avoided. According to a preferred embodiment of the present invention, insulating pads are disposed between the plurality of conductive layers 121 to ensure that the plurality of power sources do not communicate with each other.
According to a preferred embodiment of the present invention, the stationary case 11 includes a case cover body 111 and a case base 112 that can be snapped together,

it is further preferred that the brush holder 132 is fixed to the housing base 112. Because the shell cover 111 has more hollow areas, the mechanical strength of the whole shell cover 111 is insufficient, although the brush holder 132 is close to the shell cover 111, and it is convenient to directly fix the brush holder 132 on the shell cover 111, when the brush holder 132 is directly fixed on the shell cover 111, the shell cover 111 is easy to deform, which affects the service life, and on the basis, the position is improved, and the brush holder is fixed on the shell base 112, so as to enhance the mechanical strength of the device.
According to a preferred embodiment of the present invention, a bearing 14 is provided at a position where the conductive rotary shaft 12 contacts the stationary housing 11, as shown in fig. 2.

the grooves 23 have different depths, so that one water inlet channel 221 or one water outlet channel 211 is only connected with one groove 23, and water paths corresponding to different grooves 23 are not communicated with each other.
Furthermore, at least one water inlet channel 221 is connected with the cooling water tank, and the corresponding water outlet channel 211 is connected with the welding gun cold water unit.
Above-mentioned setting is in welding equipment spin welding in-process for many water routes, many gas circuits are continuously supplied water, air feed can be realized simultaneously to aqueous vapor sliding ring 2. According to a preferred embodiment of the present invention, the water-air outer shaft 22 is fixedly connected to the stationary casing 11, and the electrically conductive rotating shaft 12 rotates synchronously with the water-air inner shaft 21.
Due to the arrangement, the cable and the water-gas pipeline cannot be wound mutually in the rotation process.

Although the conductive rotating shaft 12 and the water-air inner shaft 21 can be directly fixed together, for example, the water-air inner shaft 21 is fixed on the shaft center of the conductive rotating shaft 12, this fixing method has poor safety, and is liable to cause electric leakage accidents when the water-air slip ring leaks water, and after long-term use, the water-air inner shaft 21 is eccentric and worn, so that the contact tightness between the water-air inner shaft 21 and the water-air outer shaft 22 is reduced, and the service life of the device is reduced.
In the present invention, the conductive rotating shaft 12 and the water-air inner shaft 21 are connected by the annular rotating plate 31, so that the above problems can be solved simply and effectively.
