Description

Technical Field

[0001] This utility model belongs to the field of electrical cabinet technology, and in particular relates to a drive cabinet that facilitates the replacement of frequency converters. Background Technology

[0002] Currently, a significant portion of the transmission devices on the production line use ABB R7 series frequency converters. When these frequency converters fail and need to be replaced, the following problems arise:

[0003] (1) The electrical cabinet is small. When replacing this type of frequency converter, at least two people are needed to cooperate. One person lifts the frequency converter, one person holds the frequency converter, and one person pulls it out. There is only one maintenance personnel at night, and it is difficult to complete the replacement of the frequency converter independently. By the time the day shift inspection personnel arrive, the production line has already experienced a long downtime.

[0004] (2) During the lifting process of this type of inverter, personnel can only lift the inverter by reaching their bodies into the transmission cabinet. During the exertion of force, their feet need to step on the bottom plate of the transmission cabinet, causing the bottom plate to deform and collapse, which puts stress on the incoming cable and makes personnel prone to falling. At the same time, when changing personnel to reach into the cabinet, if the power supply inside the cabinet is not completely disconnected, it is easy to cause electric shock accidents. Summary of the Invention

[0005] The purpose of this utility model is to provide a drive cabinet that facilitates the replacement of frequency converters. By setting slide rails and conversion seats inside the cabinet, the frequency converter can be suspended on the conversion seats, changing the original suspension installation method to a sliding installation method. During the installation and pushing process, the slide rails can provide support, which greatly facilitates the operation of the staff and makes it easier to replace and install the frequency converter. With the help of the frequency converter transport trolley, a single person can carry out the replacement operation, which is convenient.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a drive cabinet that facilitates the replacement of frequency converters, including a cabinet body, a conversion base and a set of symmetrically arranged slide rails;

[0008] The two slide rails are fixed to one side of the cabinet body. The end of the slide rail away from the cabinet door is fixed with a limit switch, and the other end of the slide rail is provided with a switch mechanism.

The back of the support ribs 102 is in contact with the inner side of the cabinet.

[0030] The switching mechanism 3 includes a support 301, which is fixed to the inner side of the slide rail 2. A slide rod 302 is slidably connected through the support 301. An end plate 303 is fixed to one end of the slide rod 302. A spring 304 is fixed between the end plate 303 and the support 301 and is sleeved on the slide rod 302.

[0031] The other end of the slide bar 302 is rotatably connected to a horizontal side 305, which is perpendicular to the conversion seat 1. A vertical side 306 is integrally provided on the side of the horizontal side 305 near the slide rail 2.

[0032] The inner wall of the slide rail 2 away from the limit 201 is provided with a positioning port 202, and the end gap of the vertical side 306 is provided in the positioning port 202. The two sides of the conversion seat 1 are respectively attached to the limit 201 and the vertical side 306.

[0033] Among them, such as Figure 2 As shown, the end of the slide rod 302 away from the end plate 303 is provided with a T-shaped rod head, and the transverse side 305 is provided with a T-shaped rotating sleeve. The slide rod 302 is rotatably connected to the transverse side 305 through the T-shaped rod head and the T-shaped rotating sleeve.

[0034] Among them, such as Figure 1-2 As shown, the slide rail 2 is linearly provided with several lugs 203, and the slide rail 2 is fixed to the cabinet through the lugs 203 and fasteners.

[0035] Among them, such as Figure 2 As shown, the horizontal side 305 is provided with a retaining edge 307 parallel to the vertical side 306, and the retaining edge 307 slides along the inner side of the slide rail 2.

[0038] The working principle of this utility model is as follows: When the inverter needs to be replaced, pull the horizontal side 305 towards the direction of the conversion seat 1 to pull the vertical side 306 away from the slide rail 2. Rotate the horizontal side 305 and the vertical side 306 ninety degrees to avoid blocking the slide rail 2. The conversion seat 1 with the inverter can be pulled out directly along the slide rail 2. After removing it, replace it with a new inverter. Push the conversion seat 1 between the two slide rails 2 until it contacts the limit 201. After the conversion seat 1 is positioned, pull the horizontal side 305 and the vertical side 306 again and rotate them at a certain angle. Then, the vertical side 306 is embedded into the positioning port 202 by the spring 304 to achieve fastening. Finally, connect the inverter.
