Abstract
The utility model relates to a jack pull rod of anode lifting mechanism, comprising a joint 1, a steel tube 2 and a pull rod head 3, which is characterized in that an inner screw thread is slotted on the annular joint 1 and an outer screw thread is slotted on the end of the steel tube 2 correspondingly to the joint 1; an inner screw thread is slotted on the other end of the steel tube 2 and an outer screw thread is slotted on the columniform convex section of the pull rod head 3; the steel tube 2 is fixedly connected with the joint 1and the steel tube 2 by the screw threads and an annular weld joint a1 is formed on the end wall of the joint 1 and the steel tube 2; angle weld b is formed on the section of the other end of the joint 1 sticking out from the outer wall of the steel tube 2 and a circumferential weld a2 is formed on the outer wall of the combining site of the steel tube 2 and the pull rod head 3. The utility model changes the combinations between the parts of the pull rod from the single welding to threaded connection combined with welding, therefore the combining site has the advantages of large assurance coefficient, stronger fastness and better safety.
Description
Affiliated technical field
The utility model relates to the lifting-jack pull bar of anode hoisting appliance in aluminium manufacturer's equipment.
Background technology
The used anode lifting of the electrolytic aluminum groove mechanism of aluminium manufacturer is an electrolytic aluminum groove key equipment.Working load is very strict to the requirement of lifting-jack.Pull bar in the existing weight handling equipment is the vitals of load.Prior art adds man-hour, and three parts of pull bar are divided into joint 1 ', steel pipe 2 ', drawhead 3 ', sees Fig. 2; Steel pipe 2 ' is that end face docks with joint 1 ', and the end face outside combining site is welded into circumferential weld; In the end face junction of steel pipe 2 the other ends and drawhead 3 ' also is to form boxing A.From the analytical proof to work accident: this Tiebar structure has following defective, and the one, steel pipe fixes with two parts end faces welding that just will link to each other being connected of two ends parts.Therefore, the 2nd, welding flaw since trachoma, pore, folder sand or welding penetration in the operation inadequately, not full due to, pull bar difficult quality guarantee, the loading capacity of pull bar are accident potential.
Summary of the invention
The purpose of this utility model provides the lifting-jack pull bar of the firm anode lifting mechanism of a kind of combination.
The design's joint is respectively by the internal and external screw thread connection of termination separately with being connected of steel pipe, straight mouthful of end of joint has circumferential weld, there is fillet welding in the joint and the outside, steel pipe joint portion, the steel pipe the other end has internal thread, have the drawhead of cylindric protrusion that outside screw is arranged, there is the ring-type weld seam in the outside, two joint portions.
The design's this lifting-jack Tiebar structure adds thread connection on the combining site of steel pipe fitting and two ends parts, and in the combining site outside boxing and fillet welding is arranged, in case combining site is loosening.Be that to change the combination of each parts of pull bar into thread connection by single welding fixing with welding like this.Therefore, the Tiebar structure of this form, its binding site factor of assurance is bigger, more firm, safer.
Description of drawings
Fig. 1 is the lifting-jack pull bar of the design's anode lifting mechanism;
Fig. 2 is the lifting-jack pull bar of the anode lifting mechanism of prior art;
Embodiment
The lifting-jack pull bar of anode lifting mechanism is made up of joint 1, steel pipe 2 and drawhead 3, it is characterized in that ring joint 1 has internal thread, with joint 1 corresponding steel pipe 2 ends outside screw is arranged, and sees Fig. 1; Steel pipe 2 the other ends have internal thread, and the cylinder of drawhead 3 protrudes the position outside screw; Steel pipe 2 is one with joint 1 and drawhead 3 by the screw threads for fastening of holding separately, at 1 straight mouthful of end of joint, joint 1 is reserved notch with the wall of steel pipe 2 ends with the machine adding method, and be welded into circumferential weld a1, protrude in steel pipe 2 outer wall places at joint 1 the other end and form fillet welding b, steel pipe 2 also is welded into circumferential weld a2 with drawhead 3 combining site outer walls.
Because the finish size of this Tiebar structure needs, the cylinder of drawhead 3 protrudes the working space that other part need be reserved in the position, therefore, cylindrical center is processed pre-opened hole.
