Description

Conductive tube removal tooling

(1) Technical field

The utility model relates to an assembly tool, in particular to a tool for disassembling a conductive tube of a transformer.

(2) Background technology

The conductive tube of the transformer is installed in the through hole in the middle of the transformer shell. The conductive tube and the shell need better insulation, and the insulation is realized by the insulating sleeve between the conductive tube and the through hole of the transformer shell. The insulating sleeve is provided with two groups of insulating sleeves corresponding to one side of the housing, and a V-shaped sealing ring is placed between the two groups of insulating sleeves. The conductive tube is fastened to the housing through the flange, and the inner side is axially limited by the inner convex ring of the through hole. During the assembly process, the insulating sleeve and the V-shaped sealing ring are squeezed against each other, and are limited by the through hole of the housing. . If the conductive tube needs to be disassembled, it is difficult to disassemble it because the insulating sleeve is tightly combined with the conductive tube. Under normal circumstances, it is necessary to rely on manpower to repeatedly hit the two ends of the conductive tube with wooden boards to bring out the insulating sleeve, and then the conductive tube can be pulled out of the transformer shell. Because this operation needs to hit the two ends of the conductive tube back and forth, it is easy to damage the conductive tube, and it takes a long time and the efficiency is very low.

(3) Contents of the invention

The utility model provides a conductive tube dismantling tool with high efficiency and not easy to damage the conductive tube, aiming at the defects of low efficiency and easy damage to the conductive tube at present.

The technical scheme that the utility model adopts is:

The utility model conduction tube dismantling tooling comprises a long rod bolt, a cylinder with a wooden cone head cylinder located on the side of the long rod bolt nut and a bow-shaped bracket located at the other end of the long rod screw rod, wherein the long rod bolt and the wooden cone head cylinder The body is coaxial, and the long rod bolt and the center hole of the bracket are clearance fit, and the diameter of the center hole is smaller than the long rod bolt and nut; the outer diameter of the cylindrical part of the wooden cone head cylinder is larger than the inner diameter of the conductive tube.

The utility model conduction pipe disassembly tooling includes a long rod bolt that can pass through the conduction pipe, a wooden cone head cylinder that is located on the side of the long rod bolt nut, and a bow-shaped bracket that is located at the other end of the long rod screw rod, and a wooden cone head cylinder. The cone head of the conductive pipe device is matched with the side nozzle of the insulating sleeve, the other end of the long rod bolt is put on the bracket, and the bracket is matched with the transformer shell as a limiting surface for the nut. In use, when the nut is screwed, the nut has no axial displacement due to the limit of the bow bracket, so that the screw drives the wooden cone head cylinder to move, and the cone head cylinder acts on the other end of the conductive tube to apply uniform force to the conductive tube. Static pressure pushes it out along its axial direction, while the insulating sleeve will stay in the through hole due to the limit of the convex ring in the through hole, and can be taken out directly by hand. Because the cone-head cylinder exerts static pressure on the conductive tube in this process, the impact on the conductive tube is small and the conductive tube will not be damaged. And this process only needs to install the tooling on the conductive pipe, and then screw the bolts, which is convenient to use and reliable in operation.

Fig. 1 is a structural schematic diagram of the utility model conductive tube dismounting tooling.

Among the figure: 1, wooden cone head cylinder, 2, long rod bolt, 3, nut, 4, bow-shaped support.

(5) Specific implementation methods

Example 1:

With reference to accompanying drawing 1 of illustration, conductive tube dismantling tooling, comprises long bar bolt 2, cylinder body 1 that is positioned at this long bar bolt nut side wooden conical head cylinder 1 and is positioned at the bow-shaped bracket 4 at the other end of long bar screw rod, wherein long bar bolt It is coaxial with the wooden cone head cylinder, and the long rod bolt is clearance fit with the center hole of the support. The diameter of the center hole is smaller than the long rod bolt nut 4; the outer diameter of the wooden cone head cylinder is larger than the inner diameter of the conductive pipe.

Certainly the used wooden cone head cylinder of the utility model is not necessarily to adopt wooden, also can adopt other materials, as long as the rigidity is big, it is little to the damage of conductive pipe. The main consideration of using wooden cone head cylinder is that this material is easy to process and the cost is relatively low.
