Description

Technical Field

[0001] The utility model relates to the technical field of frequency converters, in particular to a hanging type frequency converter. Background Art

[0002] The inverter is mainly composed of rectification (AC to DC), filtering, inversion (DC to AC), braking unit, drive unit, detection unit, microprocessor unit, etc. The inverter adjusts the voltage and frequency of the output power supply by the internal IGBT opening and closing, and provides the required power supply voltage according to the actual needs of the motor, thereby achieving the purpose of energy saving and speed regulation. In addition, the inverter has many protection functions, such as over-current, over-voltage, overload protection, etc. With the continuous improvement of industrial automation, inverters have also been widely used.

[0003] After searching, it was found that in a hanging inverter with patent publication number CN218733863U, it was proposed that "the screw provided by the fixing device moves the limit slot of the clamping plate to the fixing block, and the fixing block is stuck in the limit slot, so as to achieve the effect of fixing the inverter, and avoid touching the inverter when repairing the wiring port at the bottom of the inverter, thereby causing the inverter to shake and then cause the inverter to slip from the hook and fall, thereby improving the stability of the inverter hanging on the wall."

[0004] However, the above scheme still has certain shortcomings in actual use. This scheme uses a hook to hang the flat inverter, and then cooperates with the fixing devices on both sides to assist in clamping the inverter to complete the hanging of the inverter. However, this fixing method will cause the inverter to be unable to adjust its height, which makes it troublesome for workers to climb back and forth during the installation process.

[0021] See also Figure 1-4 The utility model discloses a hanging type frequency converter, comprising a frequency converter body 1 and a mounting back plate 2, wherein a movable clamping device 3 and a height adjustment device 4 are respectively arranged on the front side of the mounting back plate 2, wherein the height adjustment device 4 is located above the movable clamping device 3, and the movable clamping device 3 is movably connected with the frequency converter body 1.

[0022] The mobile clamping device 3 includes a placement plate 301, the back side of the placement plate 301 is slidably connected to a sliding bracket 302, the sliding bracket 302 is located inside the mounting back plate 2, a driving box 303 is arranged at the top of the placement plate 301, the inner wall of the driving box 303 is connected to a double-headed screw 304 through an external motor, two threaded blocks 305 are arranged on the surface of the double-headed screw 304, two sections of threads in opposite directions are opened on the surface of the double-headed screw 304, the double-headed screw 304 is threadedly connected to the threaded block 305 through threads, the movement directions of the two threaded blocks 305 are opposite, and the top of the threaded block 305 is fixedly connected to a clamping side plate 306.

[0023] The height adjustment device 4 includes a brake box 401 and a built-in motor 404. The built-in motor 404 is fixedly installed on the inner wall of the brake box 401. The inner wall of the brake box 401 is rotatably connected to a winding drum 403 through a suspension frame 402. The outer side of the winding drum 403 is fixedly connected to the output shaft of the built-in motor 404. A pulling rope 406 is wound around the surface of the winding drum 403. The other end of the pulling rope 406 is wound around a connecting buckle 407. The bottom end of the connecting buckle 407 is fixedly connected to the top of the placement plate 301.

[0024] By setting up a mobile clamping device 3 and a height adjustment device 4, the external motor included in the mobile clamping device 3 can drive the threaded block 305 to drive the clamping side plate 306 to assist in clamping the two sides of the inverter body 1 through the double-headed screw 304, and then cooperate with the built-in motor 404 included in the height adjustment device 4 to drive the pulling rope 406 to retract and release through the reel 403, so that the inverter body 1 can be fixed and the height can be adjusted at the same time, so that when the inverter is hung, there is no need for workers to climb up and down, saving manpower, and the inverter can be limited to prevent deviation and accidents.

[0025] Specifically, anti-skid pads are provided on opposite sides of the two clamping side plates 306 , and the anti-skid pads are soft silicone pads.

[0026] In this embodiment, the use of the anti-skid pad can increase the contact friction between the clamping side plate 306 and the inverter body 1 , thereby improving the clamping effect of the clamping side plate 306 and the inverter body 1 .

[0027] Specifically, a guide seat 405 is fixedly connected to the front side of the brake box 401 , and a pull rope 406 passes through the guide seat 405 and is connected to a connecting buckle 407 .

[0028] In this embodiment, the guide seat 405 can be used to directional support the vertical downward movement of the pulling rope 406, thereby improving the movement stability of the pulling rope 406.

[0029] Specifically, a distance sensor 408 is disposed on the front side of the brake box 401 , and an induction switch 409 is disposed on the back side of the connecting buckle 407 . The distance sensor 408 is electrically connected to the induction switch 409 .

[0030] In this embodiment, when the connecting buckle 407 drives the induction switch 409 to move to the highest position, an electrical signal is sent to the interior of the distance sensor 408, so that the distance sensor 408 sends an electrical signal to the built-in motor 404, thereby stopping the operation of the built-in motor 404, so that the winding disk 403 can no longer rotate, thereby avoiding the situation where the connecting buckle 407 is pulled too high and causes damage to the connecting buckle 407;

[0031] In addition, the induction switch 409 and the distance sensor 408 are both models of existing technology. At the same time, the induction switch 409 and the distance sensor 408 can also be electrically connected to the staff's wireless control terminal, so that the staff can adjust the height of the inverter body 1 at a long distance.

[0032] When in use, the inverter body 1 is first transferred to the placement plate 301, and then the external motor is started, so that the external motor drives the double-headed screw 304 to rotate. Since the double-headed screw 304 has two sections of threads in opposite directions on its surface, and the two thread blocks 305 are respectively adapted to the two sections of threads, the two thread blocks 305 will move towards or away from each other, thereby prompting the thread blocks 305 to drive the clamping side plates 306 to move synchronously, so that the two clamping side plates 306 assist in clamping the two sides of the inverter body 1, thereby completing the hanging of the inverter body 1;

[0033] When the height of the inverter body 1 needs to be adjusted, the built-in motor 404 is started, so that the output shaft of the built-in motor 404 drives the winding disk 403 to rotate, so that the pulling rope 406 wound on the surface of the winding disk 403 is unfolded or rolled up, so that the pulling rope 406 at this time drives the connecting buckle 407 along the direction of the guide seat 405 to adjust the height, so that the bottom end of the connecting buckle 407 drives the placement plate 301 to move synchronously, so that the placement plate 301 starts to move up and down along the surface of the sliding bracket 302, thereby completing the height adjustment of the inverter body 1;

[0034] When the connecting buckle 407 drives the sensing switch 409 to move to the highest point, an electrical signal is sent to the inside of the distance sensor 408, causing the distance sensor 408 to send an electrical signal to the built-in motor 404, thereby stopping the operation of the built-in motor 404, making the winding disk 403 unable to rotate at this time, thereby avoiding the connecting buckle 407 being pulled too high and causing damage to the connecting buckle 407.

[0035] In summary, the hanging inverter is provided with a mobile clamping device 3 and a height adjustment device 4. The external motor included in the mobile clamping device 3 can drive the threaded block 305 to drive the clamping side plate 306 to assist in clamping the two sides of the inverter body 1 through the double-headed screw 304, and then cooperate with the built-in motor 404 included in the height adjustment device 4 to drive the pulling rope 406 to retract and release through the winding disk 403, so that the inverter body 1 can be fixed and the height can be adjusted at the same time, so that when the inverter is hung, there is no need for workers to climb up and down, saving manpower, and the inverter can be limited to prevent deviation and accidents.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
