Background technique

In recent years, with the rapid development of power technology, many old substation equipment have been updated one after another, including a large number of isolating switches that need to be replaced. In addition, due to the surge in electricity consumption in society, many substations with a voltage level of 110kV and above are newly built every year, and many new isolating switches need to be installed. Among them, there are a large number of isolating switch mechanism boxes that need to be replaced. In view of the current situation of the replacement of the electric operating mechanism of the isolating switch, the installation quality is not high during the new installation process, the installation process is labor-intensive, the work efficiency is low, and there are potential safety hazards.

In the installation process of the electric operating mechanism of the isolating switch in the past, because the mechanism box must ensure the necessary levelness, verticality, and concentricity, it generally requires the cooperation of multiple people to lift it, and slight shaking is inevitable, resulting in low installation quality. Sparks are scattered during welding. Once the installation is found to be unqualified, it needs to be knocked off and re-welded. It is often difficult to complete it after repeated times.

Detailed ways

As can be seen from Fig. 1, Fig. 2 and Fig. 3: the upper surface of the present invention is a square platform plate 1 for placing an operating mechanism to be installed, and a hydraulic cylinder upper support plate 3 is pasted on the bottom of the platform plate 1, and the platform plate 1 There is a cross slider mechanism 4 for adjusting the position of the platform plate in the horizontal direction between the upper support plate 3 of the hydraulic cylinder, and there are four guide rod mechanisms 9 and four hydraulic pressure rod mechanisms evenly supported under the upper support plate 3 of the hydraulic cylinder. Cylinder mechanism 10, guide ejector mechanism 9 is located under the four corners of the upper support plate 3 of the hydraulic cylinder, hydraulic cylinder mechanism 10 is located in the middle of the two guide ejector mechanisms 9, and a square hydraulic cylinder is arranged at the bottom of the guide ejector mechanism 9 and hydraulic cylinder mechanism 10. The support plate 7 at the bottom of the cylinder is equipped with four universal wheels 5 at the bottom four corners of the support plate 7 at the bottom of the hydraulic cylinder, and a plurality of fixed supports for the fuselage are installed under the support plate 7 at the bottom of the hydraulic cylinder between the two universal wheels 5 6.

The installation platform is first moved to the designated position in the working area through the universal wheels, and the platform plate is adjusted to a suitable height through the hydraulic cylinder mechanism. The guide rod mechanism ensures the stability of the top support plate, and initially forms an ideal installation platform. Adjust the levelness of the top support plate through the fixed support of the fuselage fixed on the lower support plate. After the adjustment is completed, place the operating mechanism to be installed on the platform plate; it can realize rapid movement in all directions, and the fixed support feet can realize the levelness of the platform The adjustment, the hydraulic cylinder mechanism and the guide rod mechanism can realize the height adjustment of the platform up and down, and the cross slider mechanism. The position of the operating mechanism can be adjusted in the horizontal direction through the cross slider to ensure the verticality and concentricity of the whole mechanism up and down. The invention adopts the mobile type, has low cost, is convenient to use, and is easy to carry; it is easy to quickly install the electric operating mechanism of the 110kV isolating switch, and is convenient for on-site installation and maintenance.

The components in the figure are described as follows:

1) Platform plate: used to place the operating mechanism to be installed.

2) Platform plate limit bolt: When the level, verticality and concentricity of the operating mechanism are all adjusted, the position of the platform plate is limited.

3) Upper support plate of the hydraulic cylinder: located at the upper end of the hydraulic mechanism and below the platform plate, so that the force on the platform plate is uniform, and at the same time provide the installation space for the cross slider to realize the function of fine-tuning the horizontal position of the platform plate.

4) Cross slider mechanism: used to adjust the position of the platform plate in the horizontal direction, that is, to adjust the levelness and concentricity of the operating mechanism, and to realize the fine adjustment of the verticality of the operating mechanism and the vertical connecting rod of the isolation switch

5) Universal wheels: used for short-distance mobile installation platform.

6) Fixed support of the fuselage: On the one hand, the overall position of the installation platform is fixed, and on the other hand, the horizontal and vertical adjustment functions can be realized under various terrain conditions.
