Description

A damping shock absorber for transformer

Technical Field

The utility model relates to the field of transformer shock absorption, in particular to a damping shock absorber for a transformer.

Background Art

The transformer generally includes a box body, which is generally fixed directly to a bracket-shaped base through channel steel, and the base is fixed to a pole.

Furthermore, the shock absorbing assembly includes positioning grooves, which are symmetrically arranged on the two positioning plates, and a support rod is fixedly installed in the positioning groove, and a positioning ring is rotatably sleeved on the support rod.

Furthermore, support grooves are symmetrically provided at both ends of the support plate, support screws are rotatably installed between the support grooves on both sides, and the rotation directions of the threads at both ends of the support screws are opposite.

Furthermore, both ends of the support screw are threadedly connected with support blocks, wherein the support block is arranged in a concave shape, and the support block is rotatably mounted with a bearing rod through a rotating rod.

The utility model provides a damping shock absorber for a transformer, and the beneficial effects are as follows:

1. When the utility model is in use, the bevel gear rod is rotated so that the bevel gear rod drives the rotation of two supporting screws, so that the transformer is fixed after installation. By forming a negative pressure in the piston cavity, when the damping fluid absorbs vibration, the internal negative pressure pulls the transformer body at the same time, thereby fixing the transformer body and reducing the amplitude of vibration when the transformer is working. In addition, the pressure in the piston cavity can be controlled by rotating the angle of the piston rod, thereby increasing the use range of the damping shock absorber.

2. After the transformer body is installed, the bevel gear rod is rotated to drive the bevel gear head to rotate through the bevel gear rod, and then the support screw is driven to rotate, thereby driving the support block threadedly connected to the support screw to move, so that the support block moves to both sides. When the support block moves to both sides, the piston rod will rotate around the support rod through the positioning ring.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

When in use, the bevel gear rod 17 is rotated to drive the two supporting screws 10 to rotate, so that the transformer is fixed after installation. By forming a negative pressure in the piston cavity 13, when the damping fluid absorbs vibration, the internal negative pressure pulls the transformer body 1 at the same time, thereby fixing the transformer body 1 and reducing the amplitude of vibration when the transformer is working. In addition, the pressure in the piston cavity 13 can be controlled by rotating the angle of the piston rod 15, thereby increasing the use range of the damping shock absorber.

In addition, as shown in Figures 1-4, in one embodiment, the shock absorbing assembly 5 includes a positioning groove 6, which is symmetrically opened on the two positioning plates 2, a support rod 7 is fixedly installed in the positioning groove 6, and a positioning ring 8 is rotatably sleeved on the support rod 7, support grooves 9 are symmetrically opened at both ends of the support plate 4, and a support screw 10 is rotatably installed between the support grooves 9 on both sides, and the thread rotation directions of the two ends of the support screw 10 are oppositely set, and the two ends of the support screw 10 are threadedly connected with a support block 11, wherein the support block 11 is concavely set, and the support block 11 is rotatably installed with a bearing rod 12 through a rotating rod, and a piston cavity tube 13 is installed at the top of the bearing rod 12, and an auxiliary piston plate 14 is installed at the bottom of the piston cavity, and a piston rod 15 is installed on the arc bottom side of the positioning ring 8, and the piston rod 15 is connected to the piston cavity tube 13 through a main piston plate 16. A bevel gear rod 17 is rotatably installed on the side of the support plate 4, and the support plate 4 is located in the support screw 1 0 is installed with a bevel gear head 18, and the bevel gear rod 17 is meshed with the two bevel gear heads 18. After the transformer body 1 is installed, the bevel gear rod 17 is rotated, and the bevel gear head 18 is driven to rotate by the bevel gear rod 17, thereby driving the support screw 10 to rotate, thereby driving the support block 11 threadedly connected to the support screw 10 to move, so that the support block 11 moves to both sides. When the support block 11 moves to both sides, the piston rod 15 will rotate around the support rod 7 through the positioning ring 8, and at this time, the piston rod 15 and the piston cavity tube 13 will be pulled, so that the main piston plate 16 and the auxiliary piston plate 14 in the piston cavity tube 13 slide upward, so that negative pressure is formed in the piston cavity tube 13, thereby pulling the entire positioning plate 2 as a whole, and the vibration generated when the transformer body 1 starts to work is absorbed by the damping liquid injected into the piston cavity tube 13, and the negative pressure formed will reduce the range of movement of the main piston plate 16 and the auxiliary piston plate 14 in the piston cavity tube 13, thereby reducing the amplitude of the transformer body 1.

Based on the above scheme, when the utility model is actually applied, its working principle or operation process is as follows: after the transformer body 1 is installed, the bevel gear rod 17 is rotated, and the bevel gear head 18 is driven to rotate through the bevel gear rod 17, and then the support screw 10 is driven to rotate, thereby driving the support block 11 threadedly connected to the support screw 10 to move, so that the support block 11 moves to both sides. When the support block 11 moves to both sides, the piston rod 15 will rotate around the support rod 7 through the positioning ring 8, and at this time, the piston rod 15 and the piston cavity 13 will be pulled, so that the main piston plate 16 and the auxiliary piston plate 14 in the piston cavity 13 slide upward, so that negative pressure is formed in the piston cavity 13, thereby pulling the entire positioning plate 2 as a whole, and the vibration generated when the transformer body 1 starts to work is absorbed by the damping fluid injected into the piston cavity 13, and the negative pressure formed will reduce the range of motion of the main piston plate 16 and the auxiliary piston plate 14 in the piston cavity 13, thereby reducing the amplitude of the transformer body 1.

With the aid of the above-mentioned scheme of the utility model, the utility model can realize that by rotating the bevel gear rod 17, the bevel gear rod 17 drives the rotation of the two supporting screws 10, so that the transformer is fixed after installation. By forming a negative pressure in the piston cavity 13, when the damping fluid absorbs vibration, the internal negative pressure simultaneously pulls the transformer body 1, thereby fixing the transformer body 1 and reducing the amplitude of vibration when the transformer is working. In addition, the pressure in the piston cavity 13 can be controlled by rotating the angle of the piston rod 15, thereby increasing the scope of use of the damping shock absorber.
