Abstract
Description
Technical Field
[0001] The utility model relates to the field of transformers, and particularly to a transformer tie rod assembly. Background Art
[0002] The tie rod is used to obliquely pull the connection between the transformer body and the mounting seat to improve the stability of the transformer installation. However, the two ends of the traditional tie rod are locked and connected by nuts. When assembling the tie rod, a handle is required for fixation at both ends, and the operation is relatively complicated. Moreover, the threaded components at the fixed parts at both ends of the tie rod are exposed, and are prone to rust and corrosion during long-term use, resulting in inconvenient disassembly and maintenance in the later stage. Content of the Utility Model
[0003] The purpose of the utility model is to provide a transformer tie rod assembly, and solve the following technical problems: reduce the complexity of the tie rod assembly operation, and keep the threaded connection part of the tie rod not prone to rust and corrosion.
[0004] In order to solve the problems existing in the prior art, the technical scheme adopted by the utility model is as follows:
[0005] A transformer tie rod assembly includes a connecting rod. One end of the connecting rod is rotatably connected to a first hook rod. A slot is opened at the other end of the connecting rod, and a threaded groove extends inside the slot. A threaded rod is fixed at the end of a second hook rod. The second hook rod is adaptively inserted into the slot, and the threaded rod is threadedly connected to the threaded groove. The adaptation length between the second hook rod and the slot is greater than the adaptation length between the threaded rod and the threaded groove.
[0006] Preferably, a through hole is opened on the surface of the connecting rod, and the through hole penetrates the slot.
[0007] Preferably, the outer edge contour of the cross-section of the connecting rod is rectangular or hexagonal.
[0008] Preferably, a rotating seat is fixed on the surface of the connecting rod, and a torsion handle is rotatably arranged between the rotating seats.
[0009] Preferably, an axial groove is opened on the surface of the second hook rod, and a positioning column is fixed at the end of the torsion handle. When the torsion handle rotates and fits against the connecting rod, the positioning column can be snapped into the axial groove.
[0010] Preferably, a line mark is arranged on the surface of the connecting rod near one end of the second hook rod, and the line mark is aligned with the torsion handle.
[0011] Preferably, the torsion handle is in extrusion friction contact with the inner side of the rotating seat, and there is friction between the torsion handle and the rotating seat when the torsion handle rotates.
[0012] Compared with the related art, the utility model has the following beneficial effects:
[0013] 1. The utility model can achieve the effect of tightening and fixing the transformer by rotating the connecting rod to make the threaded rod contract with the threaded groove. The operation is convenient, and the threaded rod and the threaded groove are isolated from the external environment by the adaptation of the second hook rod and the slot, avoiding rust on the threaded part.
[0014] 2. The utility model can replace the tool to rotate and adjust the connecting rod by rotating the installed torsion handle. When the connecting rod is closed, the positioning post is clamped into the axial groove to limit the relative rotation of the second hook rod with respect to the connecting rod, avoiding the loosening of the connection between the threaded rod and the threaded groove.

[0019] In order to make the purpose, technical solutions and advantages of the utility model clearer, the following further describes the utility model in detail with reference to the drawings and embodiments.
[0020] As Figures 1-3 shown, the transformer pull rod assembly is composed of a connecting rod 3, a first hook rod 1, and a second hook rod 2. Both the first hook rod 1 and the second hook rod 2 are made of circular rods. The ends of the first hook rod 1 and the second hook rod 2 are bent to form hooks. An enlarged diameter groove is opened at the right end of the connecting rod 3. The end of the first hook rod 1 is inserted into the enlarged diameter groove and fixed with an enlarged diameter block. Through the limitation of the enlarged diameter block and the enlarged diameter groove, the first hook rod 1 is kept rotatably connected with the connecting rod 3;
[0021] A slot is opened at the left end of the connecting rod 3. A threaded groove is opened inside the slot. The diameter of the threaded groove is smaller than the diameter of the slot, and the length of the threaded groove is smaller than the length of the slot. The end of the second hook rod 2 is axially aligned and fixed with a threaded rod 9. The second hook rod 2 is slidably adapted to the slot, and the threaded rod 9 is threadedly adapted to the threaded groove;
[0022] When assembling the pull rod, rotate the second hook rod 2 to move the threaded rod 9 to a proper position. The lengths of the first hook rod 1, the second hook rod 2, and the connecting rod 3 are slightly greater than the length between the connecting part of the transformer and the mounting base. Hook the first hook rod 1 and the second hook rod 2 to the connecting hooks or connecting holes of the transformer and the mounting base respectively, and then rotate the connecting rod 3 to make the threaded rod 9 contract in the thread groove, shortening the lengths of the first hook rod 1, the second hook rod 2, and the connecting rod 3. The first hook rod 1 and the second hook rod 2 can then tighten the transformer and the mounting base;
[0023] The matching length of the second hook rod 2 and the slot is greater than the matching length of the threaded rod 9 and the thread groove, so that the second hook rod 2 always seals the slot, keeping the threaded rod 9 and the thread groove in a relatively sealed state to avoid being eroded by the external environment.
[0024] There are two ways to rotate the connecting rod 3. The first way is as follows:
[0025] The outer edge contour of the cross-section of the connecting rod 3 is rectangular or hexagonal. A practical adjustable wrench can be used to drive the connecting rod 3 to rotate by clamping it outside the connecting rod 3;
[0026] The second way is as follows: A rotating seat 5 is fixed on the surface of the connecting rod 3, and a torsion handle 4 is rotatably arranged between the rotating seats 5. Rotate the torsion handle 4 to a state close to being perpendicular to the connecting rod 3. The connecting rod 3 can be rotated through the torsion handle 4. The torsion handle 4 is in extrusion friction contact with the inner side of the rotating seat 5, and there is friction between the torsion handle 4 and the rotating seat 5 when the torsion handle 4 rotates. After the pull rod is installed, the torsion handle 4 can be rotated and attached to the surface of the connecting rod 3, and the torsion handle 4 is positioned through the friction force.
[0027] An axial groove 6 is opened on the surface of the second hook rod 2, a positioning column 7 is fixed at the end of the torsion handle 4, and a line mark 10 is arranged on the surface of one end of the connecting rod 3 close to the second hook rod 2. Align the line mark 10 with the torsion handle 4. When adjusting the tension of the pull rod by rotating the connecting rod 3, it is necessary to control the alignment of the axial groove 6 and the line mark 10, and then rotate the torsion handle 4 to fit it on the surface of the connecting rod 3. The positioning column 7 is clamped into the axial groove 6 to prevent the second hook rod 2 from twisting and avoid the pull rod from loosening.
[0028] A through hole 8 is opened on the surface of the connecting rod 3, and the through hole 8 penetrates the slot. Lubricating oil can be added into the slot through the through hole 8 to reduce the wear of the threaded rod 9 and the thread groove and facilitate the rotation of the connecting rod 3.
[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
