Description

The positive bar jig

Technical field

The utility model belongs to field of mechanical technique, relates in particular to a kind of positive bar jig.

Background technology

Positive bar is welded on aluminium bus of electrolyzer the requirement strictness the most in the welding procedure standard is installed.According to positive bar the design and the standard that must reach after the welding are installed following requirement is arranged: 1, the distance≤2m of two positive bar.The contact surface relative status of 2, the verticality of bus and guide rod contact surface≤± 4 ‰, and two positive bar just must keep " eight " font.If the work of bus preventing deformation fails to carry out during welding; Certainly will influence the uniform flow property (electroconductibility of anode rod and positive bar contact surface) of anode rod; Cause the touch voltage between anode rod and the positive bar excessive; The electrical discharge arc that produces can burn out the bus contact surface, makes the even variation more of dredging electrically of positive bar.Positive bar welding causes that bus is out of shape when serious, and it is inhomogeneous to cause anode block contact with ionogen in the electrolyzer, and anode block burns inclined to one side, thereby causes the phenomenon of electrolyzer local heating inequality.Above phenomenon all will have a strong impact on the smooth running and the work-ing life of electrolyzer.

In the prior art, generally adopt channel-section steel to regulate positive bar and regulate preventing deformation jig (like Fig. 3), this jig blocks positive bar A and bus B simultaneously, makes it simultaneously stressed, and this kind jig has produced a lot of disadvantages in the practice of construction use:

1, is difficult for being adjusted to required welded condition to bus; In regulate process, make asymmetric " eight " font of the stressed irregular generation of two buses easily; When regulating positive bar A through jackscrew, bus B will be simultaneously stressed, because two positive bar can produce reactive force and reactive force through jig.

2, positive bar regulate or during welding jig (channel-section steel) be easy to by longitudinal pressure or pulling force tired crooked, be difficult to grasp regulate reverse distortion-free manipulated variable, this point is to anti-welding deformation adverse factors the most.

3, be unfavorable for welding operation.Because the common jig of singularity of upper slot structure all is stuck in the welding window place, and the welding operation space is very narrow and small in the upper slot, and this kind jig will take certain space, has strengthened the difficulty of welding operation.

4, be not easy to dismounting and onsite moving, this kind jig is than heaviness and the in use yielding damage of jackscrew greatly reduces work and service efficiency.

Summary of the invention

The purpose of the utility model is to overcome above-mentioned shortcoming and a kind of deflection of being convenient to bus is provided, and anti-welding deformation does not take the welding space of bus, and is portable and smart, the positive bar jig of being convenient to remove and install.

The purpose of the utility model and solve its technical problem underlying and adopt following technical scheme to realize:

A kind of positive bar jig of the utility model; Comprise clamp A, clamp B, jackscrew A, jackscrew B, steel pipe, wherein: said clamp A and clamp B are fixedly connected on the steel pipe two ends, and clamp A is provided with governing screw A; Clamp B is provided with governing screw B, and jackscrew A and jackscrew B are fixed on the steel pipe.

Above-mentioned positive bar jig, wherein: said clamp A and clamp B are fixedly connected on the steel pipe two ends through nut A and nut B.

The utility model compared with prior art has tangible advantage and beneficial effect.Can be known that by above technical scheme clamp A and clamp B are fixedly connected on the steel pipe two ends through nut A and nut B, jackscrew A and jackscrew B are fixed on the steel pipe, and clamp A is provided with governing screw A, and clamp B is provided with governing screw B, is convenient to regulate holding clamp.During use, a pair of the utility model jig that will have with spline structure blocks bus A and bus B respectively, and two jigs are vertically symmetrical.The utlity model has following advantage:

1, the utility model has utilized the plate-girder of upper part of the electrolytic cell groove structure or the characteristics of timber truss stability, makes positive bar and upper slot plate-girder or timber truss become the relation of reactive force and reactive force through this jig jackscrew.When regulating positive bar A, do not produce any relation, avoided stressed each other " eight " font phenomenon of unbalance stress generation asymmetry that causes of two positive bar in regulate process with bus B.

2, because the upper slot structural strength is high; The stress that produces during the positive bar welding all acts on the plate-girder or timber truss of upper slot through jackscrew, is enough to offset the stress that welding produces, and makes the bus distortion less; Be convenient to grasp the reversal deformation of regulating bus, the control anti-deformation.

3, this jig is stuck between the plate-girder or timber truss and positive bar of upper slot, does not take the welding space of two positive bar, and welding operation is not had influence.

4, portable and smart being easy to made, and is convenient to especially remove and install in actual the use.

In a word; The utility model is convenient to grasp the reversal deformation amount with the regulating and controlling bus; Anti-welding deformation; Avoided stressed each other asymmetric " eight " font phenomenon of unbalance stress generation that causes of two positive bar in regulate process, do not taken the welding space of two positive bar, portable and smart being convenient to removes and installs.
