Description

Technical Field:

[0001] The utility model relates to the field of alloy smelting, and particularly relates to a fixing device for a motor frequency converter. Background Art:

[0002] Basic equipment such as purification fans, crude gas fans, and circulating water pumps are extremely common and used in large quantities in the production of workshops. However, in the actual production process, in order to further save energy and reduce emissions and ensure the stable and normal operation of the above-mentioned equipment, frequency converters are mostly equipped to transform them, so that the above-mentioned equipment can help improve the operating efficiency of the entire system and reduce energy consumption.

[0003] However, frequency converters are generally installed in substation boxes, substation cabinets, or power cabinets. Generally, they are connected through a self - contained L - shaped stainless steel sheet with punching holes, that is, connected by a connecting piece. When connecting, in order to ensure fixation, gaskets are mostly used in cooperation.

[0004] However, through long - term observation and feedback from the use in several factory areas, it is found that after a period of use, the fixation of the frequency converter becomes not very firm. Due to the large amount of vibration of the equipment in the factory area and environmental factors, the frequency converter needs to be tightened every once in a while, the screws are very easy to loosen, and the installation is also inconvenient.

[0005] Therefore, a frequency converter that is easy to install and firmly fixed is needed. Content of the Utility Model:

[0006] The purpose of the utility model is to provide a fixing device for a motor frequency converter.

[0007] The utility model is implemented by the following technical solutions:

[0008] A fixing device for a motor frequency converter includes a moving frame. The moving frame is integrally U - shaped and has a rib plate fixed at the bottom. A locking frame is arranged on one side of the moving frame. One end of the locking frame is fixedly connected with a locking bolt. One end of the locking bolt passes through the moving frame and extends into the interior of the moving frame. The locking bolt is slidably connected with the moving frame. An L - shaped backing plate is fixedly installed on the side wall of the locking frame. One end of the L - shaped backing plate passes through the moving frame and extends into the interior of the moving frame. An auxiliary backing plate is fixedly installed on the side wall of the moving frame. Both the auxiliary backing plate and the L - shaped backing plate are made of rubber materials.

[0009] Preferably, a sliding sleeve is fixedly connected to one side of the moving frame. A locking bolt is screwed on the moving frame. One end of the locking bolt extends into the sliding sleeve. A U - shaped fixing piece is inserted into the sliding sleeve and is slidably connected. Both ends of the U - shaped fixing piece are fixedly connected to the back of the frequency converter.

[0010] Preferably, extrusion rubber is fixedly installed on the side wall of the sliding sleeve.

[0011] The advantages of the utility model are as follows: the bolts are fastened inside the mobile frame, which can increase the contact area with the cross frame, thereby achieving an increased stable fixing effect; secondly, the screwing method of the bolts is changed to rotation from inside the mobile frame, leaving sufficient rotation space for more convenient operation; at the same time, the setting of the L-shaped pad and the auxiliary pad can effectively reduce vibration while increasing friction. Description of the drawings:

[0012] Figure 1 It is a schematic diagram of the structure of the utility model.

[0013] In the figure: a moving frame 1, a locking frame 2, a locking bolt 3, an L-shaped pad 4, an auxiliary pad 5, a U-shaped fixing piece 6, a sliding kit 7, and a locking bolt 8. Specific implementation method:

[0014] like Figure 1 As shown, a motor frequency converter fixing device comprises a moving frame 1, the moving frame 1 is in a U-shape as a whole, and a rib is fixed at the bottom, a locking frame 2 is arranged on one side of the moving frame 1, one end of the locking frame 2 is fixedly connected with a locking bolt 3, one end of the locking bolt 3 passes through the moving frame 1 and extends into the moving frame 1, the locking bolt 3 is slidably connected with the moving frame 1, an L-shaped pad 4 is fixedly installed on the side wall of the locking frame 2, one end of the L-shaped pad 4 passes through the moving frame 1 and extends into the moving frame 1 for rotation, and an auxiliary pad 5 is fixedly installed on the side wall of the moving frame 1 The auxiliary pad 5 and the L-shaped pad 4 are both made of rubber material. When fixing, the locking frame 2 is inserted between the horizontal frame and the back plate of the power cabinet, that is, the dotted line position in the figure, so that the bolts are fastened in the mobile frame 1. On the one hand, the contact area with the horizontal frame can be increased, thereby achieving an increased stable fixing effect. On the other hand, the screwing method of the bolt is changed to from the mobile frame 1, leaving enough rotation space, which is more convenient to operate. At the same time, the setting of the L-shaped pad 4 and the auxiliary pad 5 can effectively reduce vibration while increasing friction.

[0015] A sliding kit 7 is fixedly connected to one side of the mobile frame 1, and a locking bolt 8 is screwed on the mobile frame 1. One end of the locking bolt 8 extends into the sliding kit 7, and a slidingly connected U-shaped fixing part 6 is inserted into the sliding kit 7. Both ends of the U-shaped fixing part 6 are fixedly connected to the back of the inverter. During installation, it can be selectively installed according to the internal situation of the power cabinet. For example, there are many controllers at the current position, but the empty space for the locking cross frame is here. At this time, the locking bolt 8 can be loosened first, so that the inverter is slightly moved to one side, and then locked again. This can solve the above problem, making it convenient to install according to the actual situation without rewiring and wasting time and energy.

[0016] An extrusion rubber is fixedly installed on the side wall of the sliding kit 7 to increase the friction force, avoid loosening caused by the less tight connection between components due to long-term use, and thus avoid unnecessary vibration of the main body of the frequency converter.

[0017] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
