Problems solved by technology
[0002] At present, in the construction process of UHV and EHV DC transmission projects, most of the maintenance and replacement of thyristor valves are performed manually. Although some tools are available, these tools often have single specifications, inconvenient operation, and are easily damaged. Problems such as the valve plate bring great inconvenience to the operator and the power supply company

The invention discloses a valve block disassembly tool which comprises a transverse pipe assembly and support assemblies. The transverse pipe assembly is composed of a transverse pipe and a transverse pipe nut fixed in the transverse pipe, the support assemblies are symmetrically arranged at the two ends of the transverse pipe assembly through corner fixed frame assemblies, a lead screw traverses the transverse pipe assembly and the transverse pipe nut to form a thread transmission pair, one end of the lead screw is connected with a handle assembly for driving the lead screw, the other end of the lead screw is connected with a work part assembly through a rapid plug device, and the work part assembly is used for clamping and loosening a valve block. The tool further comprises an overload protection device which is used for limiting torque of the lead screw and is arranged between the handle assembly and the lead screw, positioning adjusting mechanisms for adjusting the width distance between the left support assembly and the right support assembly are further arranged at the two ends of the transverse pipe assembly and the corner fixed frame assemblies, and an automatic positioning mechanism for rapidly positioning, loosening and clamping the valve block is arranged on the work part assembly. The valve block disassembly tool is rapid in operation, meanwhile, the problem that in the disassembly process, the valve block is damaged due to overload can be solved, working efficiency and reliability are greatly improved, and the maintenance cost is lowered.
Description
technical field [0001] The invention relates to the field of ultra-high voltage or ultra-high voltage direct current transmission, in particular to a dismantling tool for a thyristor valve plate. Background technique [0002] At present, in the construction process of UHV and EHV DC transmission projects, most of the maintenance and replacement of thyristor valves are performed manually. Although some tools are available, these tools often have single specifications, inconvenient operation, and are easily damaged. Problems such as the valve sheet bring great inconvenience to the operator and the power supply company. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned technical problems and provide a tool for disassembling and disassembling valve discs with simple structure, fast operation and wide application range, which can quickly disassemble and disassemble valve discs, and can also protect the valve discs to a ce...
