Description

Technical Field

[0001] The utility model relates to the technical field of ship unloader frequency converter maintenance auxiliary equipment, in particular to a maintenance bracket for a ship unloader frequency converter. Background Art

[0002] At present, ship unloaders are the main equipment for loading and unloading bulk cargoes in ports. They are favored by modern terminals for their mature technology, multi-angle cargo grabbing, and high degree of automation. The inverter module is an important component of the ship unloader's electrical system. There are many of them, and the maintenance and repair time is long. It is very important to keep the inverter on the ship unloader in normal operation.

[0003] The patent application with authorization announcement number CN220254334U discloses a frequency converter bracket, and its technical solution includes: a bracket and a frequency converter, a clamping frame is installed in the middle of the top of the bracket through a dovetail groove, and the clamping frames on both sides are located on the top of the bracket and clamped with frequency converters, a side panel is installed on the top of the bracket on one side of the dovetail groove, a rotating shaft is sleeved in the middle of the side panel, and the rotating shaft is sleeved in the inside of the clamping frames on both sides, and buffer pads B are installed on the clamping frames on both sides close to the frequency converter, a buffer plate is installed on the top of the bracket at the bottom of the frequency converter, and a buffer pad A is installed on the top of the buffer plate.

[0004] However, this structure is only an installation support structure. Since the inverter module is high and heavy, it is necessary to take the inverter module out of the box for maintenance during the shutdown of the ship unloader. There is no effective support during the maintenance process. During the maintenance, the module shakes, which increases the maintenance time. When the inverter module is damaged and replaced, because the guide is generally a slope, it takes two people to cooperate with each other for 30 minutes to move the module out of the box. If the two people do not cooperate properly, the module will fall over and injure the operator or nearby equipment, causing other unnecessary damage. Utility Model Content

[0005] In order to overcome the defects in the prior art that there is no effective support during the maintenance process, and the module shakes and falls to cause damage, the utility model provides a maintenance bracket for the frequency converter of the ship unloader.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a maintenance bracket for a ship unloader frequency converter, comprising a left bracket and a right bracket, the left bracket and the right bracket are connected by a folding hinge shaft, the left bracket is provided with a left slideway, the right bracket is provided with a right slideway, the left bracket is provided with slide grooves on both the front and rear sides, one end of the support frame is slidably connected in the slide groove, and the front and rear sides of the left bracket are provided with fixed brackets capable of fixing the support frame.

[0007] As a further improvement of the utility model, the right slideway and the left slideway are both wide groove channel steels.

[0008] As a further improvement of the utility model, the right slideway and the left slideway correspond to each other and are located on the same axis.

[0009] As a further improvement of the utility model, rollers are provided at the bottom of the left bracket and the bottom of the right bracket.

[0010] As a further improvement of the utility model, the roller is a directional wheel.

[0011] As a further improvement of the utility model, the fixing bracket is a butterfly nut.

[0012] Compared with the prior art, the utility model has the beneficial effects: in this solution, the left bracket and the right bracket are connected by a folding hinge, and the folding hinge provides a rotation point for the folding of the left bracket and the right bracket. The support frame is located on the front and rear sides of the left bracket and can move and rotate along the slide groove. When the inverter module needs to be dragged out of the box, the support frame is fixed on the inverter module, and the support frame moves with the module in the groove. The support frame fixes and supports the inverter module, effectively preventing the module from tipping over and injuring people or nearby equipment, causing other unnecessary injuries and other hidden dangers.
