Hoisting tool for M2000 converter valve

Abstract

The invention relates to a hoisting tool for an M2000 converter valve. The hoisting tool comprises an electric vehicle platform, a battery pack, a lifting mechanism, a platform telescopic mechanism, a first-stage transverse sliding block mechanism, a second-stage transverse sliding block mechanism and an H-shaped supporting leg balance system, and the lifting mechanism and the platform telescopic mechanism are carried on one side of the electric vehicle platform. The upper portion of the lifting mechanism bears the first-stage transverse sliding block mechanism and the second-stage transverse sliding block mechanism through the platform telescopic mechanism, a tool position is arranged between the first-stage transverse sliding block mechanism and the second-stage transverse sliding block mechanism, and balance of the bottom of the electric vehicle platform is adjusted through an H-shaped supporting leg balance system. The other side of the electric vehicle platform is provided with an inspection control cabinet, and the top of the electric vehicle platform is provided with an operation room.

Description

technical field [0001] The invention relates to a hoisting tool for an M2000 converter valve, which is applied in the technical field of sub-module replacement devices for high-pressure flexible DC converter valves. Background technique [0002] As is known, the replacement of the M2000 high-voltage flexible direct-current converter valve sub-module needs to be disassembled first and hoisted to the ground. The new sub-module is hoisted to the corresponding height of the valve tower and moved into the installation position at a suitable angle. During this period, a total of two tasks need to be completed. One hoisting and two translations; at present, movable gantry and lifting platform trucks are generally used for hoisting and replacing sub-modules of DC converter valves, but the lack of special hoisting tools for sub-modules makes it very difficult to install sub-modules in place; and the current gantry height It does not match the height of the platform truck. After the s...

[0002] As is known, the replacement of the M2000 high-voltage flexible direct-current converter valve sub-module needs to be disassembled first and hoisted to the ground. The new sub-module is hoisted to the corresponding height of the valve tower and moved into the installation position at a suitable angle. During this period, a total of two tasks need to be completed. One hoisting and two translations; at present, movable gantry and lifting platform trucks are generally used for hoisting and replacing sub-modules of DC converter valves, but the lack of special hoisting tools for sub-modules makes it very difficult to install sub-modules in place; and the current gantry height It does not match the height of the platform truck. After the sub-module is hoisted, it cannot be directly moved into the platform truck. It is necessary to remove the fence on one side of the platform truck, which increases the difficulty of the work and greatly increases the risk.
