Description

Technical Field

[0001] The invention relates to the technical field of frequency converters, in particular to a ship unloader frequency converter which is easy to assemble and disassemble. Background Art

[0002] In real life, when unloading cargoes from ships transporting goods at ports, special ship unloaders are required, and it is very important that the frequency converter on the ship unloader maintains normal operation.

[0003] When the existing inverter is used daily on the ship unloader, the dock staff needs to regularly repair and maintain the inverter box. The existing inverter is fixed on the ship unloader by multiple screws. There are two ways to install the inverter, one is to install the inverter from the inside, and the other is to install the inverter from the outside. If the staff installs the inverter from the inside, the staff needs to remove the electronic components in the inverter before installing or removing the box, which makes the installation and removal of the inverter inconvenient. At the same time, the installation holes on the inverter need to be adjusted according to the structure of the ship unloader support frame, and the staff even need to manually open the holes, which is cumbersome. Summary of the invention

[0004] The object of the present invention is to provide a ship unloader frequency converter which is easy to assemble and disassemble, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a ship unloader frequency converter that is easy to disassemble and assemble, comprising: A box body, one end of which is provided with a side plate and a clamping and fixing structure, and both sides of the bottom end of the box body are provided with a bottom clamping structure; A clamping and fixing structure, wherein the clamping and fixing structure is provided with a clamping structure; The bottom end clamping structure has two bottom end clamping structures and the two bottom end clamping structures are symmetrically installed.
