Series compensation platform hydraulic installation system with level adjustment function

Abstract

The present invention provides a series compensation platform hydraulic installation system with a level adjustment function. The system comprises: a bearing structure comprising two gate type frames, wherein each gate type frame comprises a connection section, lifting sections and two tower frames fixed on bases, one connection section is installed between the two tower frames, and one lifting section is installed on a side of each tower frame, wherein the side of each tower frame is relative to the connection section; a steel rope type hydraulic lifting apparatus, wherein the steel rope type hydraulic lifting apparatus is connected with the bearing structure, and is provided for carrying out lifting operation on the series compensation platform; an insulator installation apparatus, wherein the insulator installation apparatus is arranged below the series compensation platform, and is provided for lifting the insulator; and level adjustment mechanisms, wherein the level adjustment mechanism is provided for carrying out level adjustment on the series compensation platform. With the present invention, lifting and lowering of the series compensation platform by the system provide advantages of stability, less impact, flexible position adjustment, safety, reliability, and the like; jamming phenomenon of the level adjustment mechanism and the series compensation platform during adjustment of the level position of the series compensation platform can be avoided; and the system can be used for installation constructions of various types of series compensation platforms (especially high-voltage level large series compensation platforms).

Description

technical field [0001] The invention belongs to the field of installation and construction of large electric equipment, and in particular relates to a hydraulic installation system with a level adjustment function for installing a series compensation platform. Background technique [0002] The use of series capacitor compensation devices (hereinafter referred to as series compensation devices) for ultra-high voltage and long-distance transmission lines can effectively improve the transmission capacity of the line, and at the same time have a good effect on improving the stability of the power system and improving the voltage quality. The structural platform of the series compensation device (hereinafter referred to as the series compensation platform) is the carrier for the installation and operation of the electrical equipment of the series compensation device. The installation quality of the series compensation platform has a very important impact on the safe and reliable o...

Problems solved by technology

Compared with the mobile crane, the above-mentioned four-pillar combined lifting equipment of the series compensation platform has been greatly improved and improved in terms of operation safety and occupied space, but there are still the following deficiencies: (1) The driving device of the lifting equipment driven by an electric motor and the The steel wire rope pulley block system lifts the series compensation platform, and the motor has a certain impact when starting and braking, which has an adverse effect on construction safety; (2) Due to the use of motor drive, the synchronous control accuracy of the four sets of hoisting equipment driving devices is not high, and the synchronous lifting error It can only reach about 50mm, and the micro-adjustment ability of a single set of lifting equipment driving device is poor, and the micro-adjustment function at the millimeter level cannot be achieved, which is not conducive to the final docking of the series compensation platform and multiple insulators; (3) to ensure construction For the safety of personnel, it is necessary to use additional safety rods to fix the series compensation platform and the hoisting frame, and the connection and release of the safety rods are inconvenient; (4) The existing horizontal adjustment mechanism and the series compensation platform are rigidly fixed in both vertical and horizontal directions. When one direction is adjusted, the other direction cannot follow up, which will cause the adjustment mechanism and the series compensation platform to be stuck, and the adjustment function will be lost. Therefore, the adjustment range of the adjustment mechanism is very small, which poses a safety hazard
