Description
Technical Field
The utility model relates to a shunt reactor double-end screw thread pull rod installation spanner belongs to shunt reactor manufacture equipment technical field.
Background
The components of the feedthrough pull rod of the shunt reactor are shown in figure 1, each feedthrough pull rod comprises a plurality of double-thread pull rods, and the length of each double-thread pull rod is different from 2 meters to 3.5 meters according to the capacity of the shunt reactor. The double thread pull rod passes the internal thread on backing plate and the nut and closes soon, because contain many double thread pull rods in every heart pull rod of wearing, installation space is narrow and small, can't use traditional spanner for backing plate and the internal thread of nut close soon the fastening difficulty.
Disclosure of Invention
The utility model aims at providing a shunt reactor double-end screw thread pull rod installation spanner through the use of revolving the thick stick, can realize that the quick of double-end screw thread pull rod and nut closes the fastening soon, and convenient to use is swift, improve work efficiency, has solved the above-mentioned problem that exists effectively among the background art.
The technical scheme of the utility model is that: a wrench for installing a double-end threaded pull rod of a shunt reactor comprises a first nut, a sleeve, a large screw rod, a small screw rod and a screw rod, wherein an inner hole of the first nut is of a reducing step structure, the inner diameter of a head end is larger than that of a tail end, an internal thread of the head end of the first nut is matched with an external thread of the double-end threaded pull rod, and the first nut and the second nut are screwed mutually; the first nut is in welded connection with the head end of the sleeve, the tail end of the sleeve is in vertical welded connection with the large rotating rod to form a T shape, the screw rod penetrates through the large rotating rod and the sleeve to be screwed with the tail end of the first nut, and the other end of the screw rod is in vertical welded connection with the small rotating rod to form the T shape.
The external thread of the screw is matched with the end thread of the first nut.
The utility model has the advantages that: through the use of the rotary rod, the double-thread pull rod and the nut can be quickly screwed and fastened, the use is convenient and quick, and the work efficiency is improved.
Drawings
FIG. 1 is a schematic diagram of a feedthrough pull rod structure of a shunt reactor in the background art of the present invention;
fig. 2 is a schematic structural diagram of the present invention;
in the figure: the double-thread pull rod comprises a double-thread pull rod 1, a base plate 2, a small nut 3, a washer 4, a nut 5, a first nut 6, a sleeve 7, a large rotary rod 8, a small rotary rod 9 and a screw rod 10.
Detailed Description
The technical solution of the present invention will be further described in detail with reference to the accompanying drawings and embodiments.
A wrench for installing a double-end threaded pull rod of a shunt reactor comprises a first nut 6, a sleeve 7, a large screw 8, a small screw 9 and a screw 10, wherein an inner hole of the first nut 6 is of a reducing step structure, the inner diameter of the head end is larger than that of the tail end, the inner thread of the head end of the first nut 6 is matched with the outer thread of the double-end threaded pull rod 1, and the first nut and the second nut are screwed mutually; the first nut 6 is in welded connection with the head end of the sleeve 7, the tail end of the sleeve 7 is perpendicularly welded and connected with the large screw 8 to form a T shape, the screw 10 penetrates through the large screw 8 and the sleeve 7 to be screwed with the tail end of the first nut 6, and the other end of the screw 10 is perpendicularly welded and connected with the small screw 9 to form the T shape.
The external thread of the screw rod 10 is matched with the end thread of the first nut 6.
In practical application, the first nut 6 is screwed with one end of the double-thread pull rod 1 by 15-20mm, but not to the end, the small screw 9 is rotated to drive the screw 10 to rotate to be tightly propped against the end part of the double-thread pull rod 1, so that the screw thread of the first nut 6 and the double-thread pull rod 1 generates pretightening force, and the large screw 8 is rotated to drive the double-thread pull rod 1 to rotate to be screwed and fastened with the screw thread of the first nut 6. And after fastening is finished, the small reverse rotation lever 9 is rotated reversely to separate the screw 10 from the double-thread pull rod 1, the pre-tightening force of the first nut 6 and the double-thread pull rod 1 is unloaded, and the large reverse rotation lever 8 is rotated reversely to separate the first nut 6 from the double-thread pull rod 1, so that the installation and fastening of the double-thread pull rod are completed.
