Description

A transformer carrier with a single electric jack

technical field

The utility model relates to the technical field of transformer transport vehicles.

Background technique

According to the "Preventive Test Regulations for Electric Power Equipment", the voltage transformer needs to be subjected to a withstand voltage test before it is put into operation and after overhaul to verify its insulation performance. This is because the transformer must ensure that the withstand voltage test data is qualified before it can be installed and put into operation during the delivery process and after overhaul. If such a transformer with poor insulation performance is put into operation, it is very easy to cause breakdown of the transformer, malfunction of protection, and affect the stable operation of the power grid. Therefore, performing a withstand voltage test on the transformer is an effective method to verify its insulation performance.

In the withstand voltage test of the transformer, it is necessary to transport the transformer to the station for the withstand voltage test. After connecting the relevant test wiring, carry out the withstand voltage for one minute, observe the test current and whether there is a discharge sound. After the test, Remove the test wiring and move the transformer to the qualified product area. The transformer generally weighs 80 kg to 120 kg. It is heavy and irregular, and it is inconvenient to use force. All four workers need to work hard at the same time to move the transformer. Since it cannot be carried upright, it is easy to hurt people during the transfer. lumbar spine.

Contents of the invention

The utility model provides a transformer transport vehicle with a single electric jack which can be operated by only one person and does not cause personal injury.

In order to solve the above problems, the utility model adopts the following technical solutions:

A transformer truck with a single electric jack, including a stainless steel frame trolley with universal wheels on the bottom, an electric jack placed on the stainless steel frame, a rectangular adjusting beam installed on the top surface of the electric jack, and a stainless steel frame trolley The jack control box on the outside; the stainless steel frame includes a horizontal trough-shaped bottom frame with one side open, two mutually parallel gantry-type vertical frames installed on the bottom frame, and a support between the top beams of the two gantry-type vertical frames. Beam; the electric jack is installed in the middle of the top surface of the supporting beam, and a drooping steel rope with a hook at the bottom end is respectively installed on the four corners of the rectangular adjusting beam.

In the utility model, the electric jack is set on the transport vehicle, and the transformer can be hoisted by lifting the jack to a certain height and then moved smoothly along with the progress of the cart, and the transformer can be easily put down when it moves to a designated place, saving time and effort Greatly improved handling efficiency. The utility model realizes the lifting by using the electric jack, and no longer uses manpower to lift and lower, thus avoiding the risk of personal injury.

Fig. 1 is the structural representation of the utility model.

detailed description

The transformer truck with a single electric jack as shown in Figure 1 includes a stainless steel frame trolley with universal wheels 1 on the bottom, an electric jack 5 placed on the stainless steel frame, and a rectangular adjustment beam installed on the top surface of the electric jack 6. The jack control box 2 arranged on the outside of the stainless steel frame trolley; the stainless steel frame includes a horizontal trough-shaped underframe 8 with one side open, two mutually parallel gantry-type stands 3 installed on the underframe, connected to the two The support beam 7 in the middle of the top beam of a gantry type vertical frame; the electric jack 5 is installed in the middle position of the top surface of the support beam 7, and a drooping steel rope 4 with a hook at the bottom is respectively installed on the four corners of the rectangular adjustment beam 6 . The four hooks on the four steel ropes are connected to the four hook holes of the transformer, and then the electric jack on the stainless steel bracket is used to realize the rising and falling of the transformer

The utility model is as follows on-the-spot application method:

Step 1: Adjust the electric jack 5 and lower it to the lowest position;

Step 2: Move the stainless steel frame trolley to the position where the transformer is located, and place the transformer in the frame through the opening of the horizontal groove-shaped bottom frame 8;

The third step: adjust the support beam 7, so that the four hooks at the bottom of the four steel ropes 4 can smoothly hook the four hooks of the transformer;

Step 4: Start the jack control box 2, the electric jack lifts up, drives the wire rope to lift the transformer up, and stops when it rises about 10cm from the ground;

Step 5: Slowly push the stainless steel frame trolley hanging the transformer to the pressure test station, adjust the electric jack control box after it is in place, return the electric jack downward, slowly lower the transformer to the ground, and remove the four hooks, Move the stainless steel frame trolley out of the test area and start the test. After the test, use the same method to move the transformer to the designated position and put it away.
