In Pressure Vessel Manufacture Process, the general employing of Circumferential Welds In Cylinders welding Lincoln weld.In order to ensure downhand position, its cylindrical shell need to be positioned on turning rolls and be rotated, and this just makes welding ground be connected comparatively difficulty with cylindrical shell.Existing earth connection utilizes pressing plate to be attached to cylinder body outer wall, and this earthing mode is connected not tight with cylindrical shell, very easily produces loose contact and causes electric current unstable, along with the rotation of cylindrical shell also can produce electric spark, cylindrical shell is caused to damage.
Summary of the invention
Overlay in cylinder body outer wall loose contact and easily cause electric current unstable in order to overcome in prior art earth connection, and can produce electric spark cylindrical shell is caused the deficiency of damage, the utility model provide a kind of simple in structure, make easily, connect reliable, welding current is stable, can effectively avoid the rotary e grounding wire clip of electric spark damage cylindrical shell.
The utility model solves the technical scheme that its technical problem adopts: a kind of rotary e grounding wire clip, it comprises a ground wire connecting plate, it is characterized in that: described ground wire connecting plate is welded on a rotary sleeve, this rotary sleeve turning set is contained on a conductive shaft, one end of conductive shaft removable or non-disconnectable be connected to a gripping fork concrete on, the other end of conductive shaft is provided with restricting rotation and overlaps axially movable locating part, Screw assembly one fishbolt on described gripping fork is concrete.
Described locating part is made up of gland, butterfly spring and screw, described gland cover is buckled on rotary sleeve, described butterfly spring is arranged between gland and rotary sleeve, described screw is threaded with described conductive shaft through gland, butterfly spring, through gland, butterfly spring is pressed on the end face of rotary sleeve.
Non-disconnectable concrete with gripping fork of described conductive shaft be connected be by conductive shaft one end be directly welded on gripping fork concrete on.
The concrete releasable connection of described conductive shaft and gripping fork is to be provided with mount pad in one end of conductive shaft, and described gripping fork is specifically provided with Connection Block, and between described mount pad and Connection Block, bolt is connected.
Parts of the present utility model adopt the full copper product with satisfactory electrical conductivity to make, and it is simple in structure, making is easy; Gripping fork is specifically installed on cylindrical shell through fishbolt, welding cable is electrically connected with ground wire connecting plate, and gripping fork specifically rotates jointly along with cylindrical shell, and rotary sleeve relatively rotates on conductive shaft, make to weld cable all the time in sagging state, prevented that welding cable is wound around; Rotary sleeve relatively rotates in process and contacts reliably with conductive shaft, makes welding current stable, and weld seam welding quality is good, avoids producing electric spark simultaneously, effectively protects cylindrical shell.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described further.
Fig. 1 is a kind of structure cutaway view of the present utility model.
Mark in figure: 1. connecting plate, 2. locating part, 201. glands, 202. screws, 203. butterfly springs, 3. rotary sleeve, 4. conductive shaft, 5. connecting bolt, 6. mount pad, 7. Connection Block, 8. gripping fork is concrete, 9. fishbolt.
Embodiment
In Fig. 1, a kind of rotary e grounding wire clip, it comprises a ground wire connecting plate 1, has connecting hole on it.When use, will weld cable and be electrically connected with ground wire connecting plate 1 through its connecting hole.
As shown in Figure 1, ground wire connecting plate 1 is welded on a rotary sleeve 3.Rotary sleeve 3 turning sets are contained on a conductive shaft 4.
One end releasable connection of conductive shaft 4 is on a gripping fork concrete 8.Its releasable connection organization plan is: as shown in Figure 1, be shaped with mount pad 6 in one end of conductive shaft 4 with material, on gripping fork concrete 8, be shaped with or be welded with Connection Block 7 with material, adopt two connecting bolts 5 to be connected between mount pad 6 and Connection Block 7.
In order to increase conductive shaft and the gripping fork satisfactory electrical conductivity between concrete, in specifically also practicable non-disconnectable connection of one end of conductive shaft and gripping fork, its non-disconnectable connection scheme is (in figure, not providing): one end of conductive shaft 4 is directly welded on gripping fork concrete 8.
In Fig. 1, Screw assembly one fishbolt 9 on gripping fork concrete 8.
For restricting rotation cover 3 moving axially on conductive shaft 4, on one end of conductive shaft 4, establish the shaft shoulder, the locating part 2 that the other end is provided with.
It should be noted that, locating part can adopt circlip, or adopts the parts of other structures.
As shown in Figure 1, in the present embodiment, locating part 2 is made up of gland 201, butterfly spring 203 and screw 202, gland 201 covers are buckled on rotary sleeve 3, butterfly spring 203 is arranged between gland 201 and rotary sleeve 3, screw 202 is threaded with conductive shaft 4 through gland 201, butterfly spring 203, butterfly spring 203 is pressed on the end face of rotary sleeve 3 through gland 201, control the degree of tightening of screw 202 and conductive shaft 4, both ensured that rotary sleeve 3 was adjacent to and contacts with the shaft shoulder of conductive shaft 4 under the effect of butterfly spring 203, and can ensure that again rotary sleeve 3 rotated on conductive shaft 4.
When use, clamp and can start to carry out welding operation with cylindrical shell end concrete gripping fork 8 by tightening fishbolt 9.Along with the rotation of cylindrical shell, gripping fork concrete 8 is in company with cylindrical shell rotation, and the rotary sleeve 3 welding with ground wire connecting plate 1 relatively rotates on conductive shaft 4, and the welding cable being electrically connected with ground wire connecting plate 1 is all the time in sagging state, has effectively prevented cable winding.
The parts of the present embodiment all adopt the full copper product with satisfactory electrical conductivity to make, and rotary sleeve 3 relatively rotates in use procedure on conductive shaft 4, and rotary sleeve 3 remains good contact with conductive shaft 4, make welding current stable, and weld seam welding quality is good.Meanwhile, gripping fork concrete 8 is connected reliably with cylindrical shell, avoids producing electric spark, effectively protects cylindrical shell.
The utility model is applicable to various large electric current welding methods, current stabilization, and firm and reliable connection, is a kind of very practical earthing device.
