Description

Technical Field

[0001] The utility model relates to the technical field of power equipment installation, and more specifically to a high-voltage transformer clamping frame installation structure. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are primary coil, secondary coil and iron core. Its main functions include voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization, etc. According to their uses, they can be divided into power transformers and special transformers. Special transformers include electric furnace transformers, rectifier transformers, industrial frequency test transformers, voltage regulators, mining transformers, audio transformers, medium frequency transformers, high frequency transformers, impact transformers, instrument transformers, electronic transformers, reactors, mutual inductors, etc.

[0003] Existing high-voltage transformers are generally installed on a mounting frame between two electric poles, but the existing high-voltage transformers do not have a clamping mounting structure. If all bolts are used for installation, it will be very troublesome to install the high-voltage transformer, which is not conducive to use. An existing patent is a high-voltage transformer with a clamping mounting structure. The patent announcement number is CN210443385 U. The patent solves the problem that the existing high-voltage transformer has no clamping mounting structure and is inconvenient to install by setting a transformer body, a column, a mounting frame, a fixing box, a first hand wheel, a first threaded rod, a threaded sleeve, a push plate, a support rod, a clamping plate, a push rod, a threaded hole, a second hand wheel, a rotating rod, a pressure plate and a second threaded rod. The high-voltage transformer has the advantage of being easy to install with a clamping mounting structure.

[0004] However, in the patent announcement number CN 210443385 U, the first hand wheel is rotated, the first hand wheel drives the first threaded rod to rotate, the rotation of the first threaded rod drives the upper and lower threaded sleeves to move toward each other, the threaded sleeve drives one end of the support rod to move toward each other, and the other end of the support rod will drive the two clamping plates to move away from each other through the cooperation of the push plate and the push rod, the clamping plates gradually approach the column until they are close to each other, so as to fix the transformer body, and then move the second hand wheel, the second hand wheel drives the second threaded rod to insert into the jack through the cooperation of the rotating rod and the pressure plate, and rotate the second hand wheel, through the cooperation of the rotating rod and the pressure plate, drives the second threaded rod to rotate and insert into the threaded hole, so as to further fix the transformer body, this operation process is relatively cumbersome. In order to be able to install and clamp the high-voltage transformer and optimize the installation steps, we have proposed a high-voltage transformer clamping frame installation structure to solve the above-mentioned problems. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a high-voltage transformer clamping frame installation structure, which realizes the installation and clamping of the high-voltage transformer body, optimizes the installation steps, and is very convenient to install.

[0006] To solve the above problems, the utility model adopts the following technical solutions.

[0007] The high-voltage transformer clamping frame installation structure comprises a high-voltage transformer body, the bottom edge of the high-voltage transformer body is fixedly connected with a foot, and a plurality of the foots are symmetrically arranged in pairs;

[0008] The root of the high-voltage transformer body is surrounded by columns, and the columns are provided with guide grooves near the corners of the high-voltage transformer body, and the inner wall of the guide groove is in contact with the outer wall of the corner of the high-voltage transformer body;

[0009] A connecting rod is welded between two adjacent columns, and a clamping plate arranged in a C-shaped structure is rotatably connected to the middle part of the connecting rod, the top end of the clamping plate abuts against the outer wall of the root of the high-voltage transformer body, and the upper surface of the bottom end of the clamping plate abuts against the bottom of the foot;

[0010] Positioning blocks fixedly connected to the connecting rod are provided on both sides of the clamping plate, and a torsion spring is sleeved on the portion of the connecting rod between the positioning block and the clamping plate. The elastic force of one end of the torsion spring abuts against the surface of the clamping plate close to the high-voltage transformer body, and the elastic force of the other end of the torsion spring abuts against the surface of the positioning block away from the high-voltage transformer body.

[0011] Furthermore, a rib is welded at the junction of the end of the connecting rod and the connecting rod, and the rib is arranged in a right-angle trapezoidal structure.

[0012] Furthermore, a slot engaged with the connecting rod is formed on the top of the rib plate, and the connecting rod is connected to the edge seam of the slot by welding.

[0013] Furthermore, a through hole is provided at the junction of the clamping plate and the connecting rod, and the inner diameter of the through hole is matched with the outer diameter of the connecting rod.

[0014] Furthermore, the surfaces of the clamping plate and the positioning block that abut against the elastic end of the torsion spring are both provided with clamping grooves.

[0015] Furthermore, a channel steel is welded to the bottom end of the column, and assembly holes are provided at both ends of the channel steel.

[0016] Furthermore, a lifting lug is welded on the top edge of the high-voltage transformer body, and a plurality of the lifting lugs are symmetrically arranged in pairs.

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] (1) In this scheme, the initial position of the clamp is when the torsion of the torsion spring cooperates with the positioning block to flip outward. When hoisting the high-voltage transformer body, the outer wall of the root corner of the high-voltage transformer body is made to correspond to the guide groove set at the column. Then, the high-voltage transformer body is guided during the descent so that the bottom foot can abut against the bottom end of the clamp, so that the clamp cooperates with the connecting rod to flip. When the top end of the clamp abuts against the root outer wall of the high-voltage transformer body, the clamp stops rotating, completing the clamping and fixing of the high-voltage transformer body, realizing the installation and clamping of the high-voltage transformer body, optimizing the installation steps, and making the installation very convenient.

[0019] (2) In this scheme, the structural strength of the connection between the connecting rod and the column can be improved by providing a rib plate, thereby preventing the connecting rod from bending and deforming under the impact force of downward pressure. At the same time, the groove is provided to increase the cross-sectional area of ​​the connection between the rib plate and the connecting rod, thereby ensuring the connection stability between the rib plate and the connecting rod.

When hoisting the high-voltage transformer body 1, the outer wall of the root corner of the high-voltage transformer body 1 is made to correspond to the guide groove 4 set at the column 3, and then the high-voltage transformer body 1 is guided during the descent process so that the base 2 can abut against the bottom end of the clamping plate 6, so that the clamping plate 6 cooperates with the connecting rod 5 to flip. When the top end of the clamping plate 6 abuts against the outer wall of the root of the high-voltage transformer body 1, the clamping plate 6 stops rotating, completing the clamping and fixing of the high-voltage transformer body 1.
