Technical Field

[0001] The present application relates to the technical field of power transformers, and in particular to a power transformer mounting frame. Background Art

[0002] A power transformer is a static electrical device that is used to convert an AC voltage (current) of a certain value into another or several different voltages (currents) of the same frequency. Its main function is to transmit electrical energy. Therefore, the rated capacity is its main parameter. Our common power transformers are generally installed between two poles through a rack. When installing a power transformer, it is generally hoisted by a crane. Before hoisting, it is required to install the cross arm of the transformer on the pole (with channel steel) and a triangular bracket welded with angle iron under the cross arm, which is fixed with a U-shaped or semicircular clamp.

[0003] However, the traditional installation method of power transformer still has the following defects: the clamp is basically welded on the cross arm or the triangular bracket, and the clamping force between the clamp and the pole cannot be adjusted in time according to the diameter change of the pole, so it is easy to cause the clamping force between the clamp and the pole to be insufficient, resulting in the danger of the cross arm driving the transformer to slide down. Therefore, those skilled in the art provide a power transformer mounting frame to solve the problems raised in the above background technology. Utility Model Content

[0005] The present application provides a power transformer mounting frame adopting the following technical solution:

[0006] A power transformer mounting frame comprises two cross beams symmetrically arranged front and back, the left and right ends of the two cross beams are symmetrically slidably connected with fixing rods, one end of the fixing rod away from the cross beam is symmetrically provided with clamps front and back, an adjustment component is arranged between the clamps and the fixing rods, and a fastening bolt is threadedly connected between the ends of the two clamps close to each other.

[0007] Preferably, the adjustment assembly includes an open groove, a sliding block, a bidirectional screw and a rotating knob. The open groove is arranged at one end of the fixed rod away from the cross beam. A sliding block is symmetrically slidably connected in the open groove front and back. A bidirectional screw is connected between the two sliding blocks by threaded cooperation. The front end of the bidirectional screw rotates through the fixed rod and is fixedly connected to the rotating knob.

[0008] Preferably, a plurality of reinforcement plates are evenly installed between the two cross beams from left to right.

[0009] Preferably, installation grooves are symmetrically provided at the front and rear ends of the reinforcement plate, a movable rod is slidably connected in the installation groove, and one end of the movable rod away from the reinforcement plate is fixedly connected to the crossbeam.

[0010] Preferably, locking bolts are threadedly connected between the two movable rods at the leftmost end of the beam and the two movable rods at the rightmost end of the beam and the reinforcement plate.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] Before installing the power transformer, the present invention can manually rotate the rotating knob to rotate the bidirectional screw. Under the limiting effect of the open slot, the two sliding blocks drive the two clamps to move in a straight line toward or away from each other, thereby achieving the effect of timely and rapid adjustment of the clamping force between the clamp and the cement pole according to the change in diameter of the cement pole. At the same time, the mounting frame can also be adapted to poles of various diameters. BRIEF DESCRIPTION OF THE DRAWINGS

The front end of the bidirectional screw 42 rotates and penetrates the fixed rod 2 and is fixedly connected with a rotating knob 43. Before installing the power transformer, the rotating knob 43 can be manually rotated to rotate the bidirectional screw 42. Under the limiting action of the open groove 40, the two sliding blocks 41 drive the two clamps 3 to move in a straight line toward or away from each other, thereby achieving the effect of timely and quickly adjusting the clamping force between the clamp 3 and the cement pole according to the diameter change of the cement pole. At the same time, it can also make this type of mounting frame adaptable to poles of various diameters, and then the two clamps 3 can be locked to the poles by tightening bolts 5.
