Further, in the present invention, the specific implementation method of electrically connecting each annular conductive layer 121 with only one conductive post 122 is not limited, and those skilled in the art can implement the implementation according to actual needs, for example, an insulating sleeve is sleeved outside the conductive post 122, so that electrical conduction will not occur when the conductive post 122 contacts with other conductive layers 121 without electrical connection.
According to a preferred embodiment of the present invention, pin holes are provided at the inner side of the conductive layer 121 and at the corresponding positions of the conductive rotating shaft 12 to fix the two through the pins.
Although the conductive layer 121 and the conductive shaft 12 may be fixed together by the conductive post 122, a large radial force is generated due to the continuous friction between the conductive layer and the brush, and the radial force is finally applied to the connection position between the conductive post 122 and the conductive layer 121, so that the connection strength between the conductive post 122 and the conductive layer 121 is reduced, resulting in a reduction in the service life of the device. In the invention, the pin shaft is arranged to fix the conductive layer 121 and the conductive rotating shaft 12, so that damage of radial force to the connection position of the conductive column 122 and the conductive layer 121 can be greatly reduced.
According to the welding equipment with the slewing device, which is disclosed by the invention, the welding equipment is used for welding the steam generator in the nuclear power field, and the welding quality of the steam generator is extremely high, so that the welding equipment cannot be required to have large shaking during rotary welding, namely the conductive slip ring is required to rotate smoothly, and the phenomena of rotary clamping, conductive shaft shaking 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 shaft 12 is prevented from shaking due to the eccentric wear phenomenon 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 fixed housing 11, and a brush core 131 mounted inside the brush holder 132,
the brush holder 132 is a box body,
one end of the brush core 131 is a cambered surface, so that the brush core can be attached to the side surface of the annular conductive layer 121.
In order to improve the smoothness of the conductive slip ring, reduce the problems of rotational jamming and rotational vibration, 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.
The actual use finds that the brush core 131 is directly used to contact with the annular conductive layer 121, after long-term use, the brush core 131 is easy to be eccentric-wear, the annular conductive layer 121 is uneven in stress, the annular conductive layer 121 is abnormally worn, and the problems of rotation blocking and rotation shaking are extremely easy to occur. In the invention, by arranging the columnar conductive roller 15, the sliding friction between the brush 13 and the conductive layer 121 is changed into rolling friction, so that the wear rate is greatly reduced, and the rotating smoothness of the conductive slip ring is improved.
In one embodiment, the upper and lower ends and sides 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.

Because the conductive roller 15 is not fixed with one of the brushes 13 any more, that is, all the conductive rollers 15 are shared by the plurality of brushes 13, the problem of shaking when the conductive slip ring rotates due to the fact that one conductive roller 15 is worn greatly can be avoided. In a preferred embodiment, a spring is provided between the brush holder 132 and the brush core 131, and the brush core 131 is pressed against the conductive layer 121 by the spring to press the brush core 131.
In a preferred embodiment, the brush holder 132 is a square box body, so that the brush holder 132 can be sleeved on the brush core 131, and the brush holder 132 of the square box body plays a guiding role, so that the brush core 131 can only move towards the radial direction of the annular conductive layer 121, thereby avoiding shaking of the brush core 131 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.
Fixing the cable on the brush holder 132 avoids unstable power supply caused by the fact that the brush core 131 is not tightly combined with the conductive layer 121 or the conductive roller 15 due to shaking of the cable compared with the fact that the cable is directly connected with the brush core 131. According to a preferred embodiment of the present invention, an insulating pad is provided 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 fixed housing 11 includes a housing cover 111 and a housing base 112 that can be snapped together,

further preferably, the brush holder 132 is fixed to the housing base 112. Because the shell cover 111 has more hollow areas, the whole mechanical strength of the shell cover 111 is insufficient, and although the brush frame 132 is close to the shell cover 111, the brush frame 132 is directly and conveniently fixed on the shell cover 111, when the brush frame 132 is directly fixed on the shell cover 111, the shell cover 111 is easy to deform, the service life is influenced, and based on the deformation, the brush frame is fixed on the shell base 112, so that the mechanical strength of the device is enhanced.
According to a preferred embodiment of the present invention, a bearing 14 is provided at a position where the conductive rotating shaft 12 contacts the stationary housing 11, as shown in fig. 2.

Further, at least one water inlet channel 221 is connected to the cooling water tank, and a corresponding water outlet channel 211 is connected to the torch cold water unit.
The arrangement enables the water-gas slip ring 2 to simultaneously realize continuous water supply and gas supply of a plurality of waterways and a plurality of gas paths in the rotary welding process of the welding equipment. According to a preferred embodiment of the present invention, the water vapor outer shaft 22 is fixedly connected to the fixed housing 11, and the conductive rotating shaft 12 rotates in synchronization with the water vapor inner shaft 21.
By the arrangement, in the rotation process, the cables and the water and gas pipelines cannot be intertwined.

Although the conductive rotating shaft 12 and the water-air inner shaft 21 can be directly and fixedly connected together, for example, the water-air inner shaft 21 is fixedly connected to the shaft center of the conductive rotating shaft 12, the fixing mode is poor in safety, electric leakage accidents are easy to occur when the water-air slip ring leaks water, and the water-air inner shaft 21 is eccentric after long-term use, 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 prolonged.
In the present invention, the above problems can be simply and effectively solved by connecting the conductive rotating shaft 12 and the inner water-air shaft 21 through the annular rotating plate 31.
