Description

Technical Field

[0001] The invention relates to the technical field of electrical cabinets, and in particular to an environmentally friendly electrical cabinet with a lifting function. Background Art

[0002] An electrical cabinet is a metal cabinet used to house and protect electrical equipment. It is usually made of steel or aluminum plates, and has good protective properties, which can prevent electrical equipment from being disturbed and damaged by the outside world. Various electrical components are usually installed inside the electrical cabinet, such as circuit breakers, contactors, relays, fuses, transformers, etc. These components can realize functions such as control, protection and measurement of electrical equipment. There are many types of electrical cabinets, which can be divided into low-voltage electrical cabinets, high-voltage electrical cabinets, distribution boxes, control cabinets, etc. according to different uses and installation environments.

[0003] According to a disclosed electrical cabinet with a lifting function (publication number: CN108365526A), in the above application, when the electrical cabinet is lifted or lowered, the wires connected to the electrical cabinet will rub against the edge of the electrical cabinet during the lifting process, which will increase the wear of the wires and reduce the service life of the wires. In addition, the electrical cabinet will also pull the wires when it is lifted or lowered. At the same time, most of the wires inside the electrical cabinet use copper core wires. If the copper core wires are bent, they cannot naturally maintain a straight line. If the electrical cabinet is repeatedly lifted or lowered, the wires will be deformed, causing the wires to become entangled. In addition, when used at a construction site or in a non-sealed environment, dust can easily enter the electrical cabinet through the wire threading position, affecting subsequent maintenance and other work.

Since the screw sleeve 49 is passed through and threadedly connected by the reciprocating screw rod 48, and the guide ring 411 on the surface of the screw sleeve 49 passes through the limiting rail 410, when the reciprocating screw rod 48 rotates, the guide ring 411 is located in the limiting rail 410 and slides back and forth.

[0025] The top of the rotating rod 10 passes through and is fixedly connected with a lifting screw 12, and the side of the electrical cabinet body 1 is fixedly connected with a lifting block 13, which passes through the lifting frame 5 and is slidably connected. When the electrical cabinet body 1 is lifted or lowered, the motor 8 is started so that the output shaft of the motor 8 drives the bevel gear 1 9 to drive the bevel gear 2 11 to rotate, so that the bevel gear 2 11 drives the lifting screw 12 to rotate through the rotating rod 10, so that the lifting screw 12 drives the threaded lifting block 13 to rise upward, the lifting screw 12 passes through the lifting block 13 and is threadedly connected, and the side of the electrical cabinet body 1 is fixedly connected with a triangular block 14 and a roller 15.

[0026] Based on the above embodiment, before the line of the electrical cabinet body 1 is connected, first open the external junction box 21, wind the power coil around the winding roller 42, and then pass the wire end through the guide ring 411. After the line end passes through the guide ring 411, it is passed through the rubber sealing sleeve 230 in the protective part 2 and the sealing sleeve ring 315 in the positioning part 3. At this time, the wire end is located on the inner side of the electrical cabinet body 1, and the wire can be connected to the electrical cabinet firmware 7. After the wire entering the cabinet is connected to the electrical cabinet firmware 7, the rotating disk 32 is first rotated so that the contact groove 33 on the inner side of the rotating disk 32 contacts the round rod 39, thereby forcing the round rod 39 to slide in the contact groove 33. Since the round rod 39 is fixedly connected to the slider 35, and the slider 35 is limited by the slide groove 34, the round rod 39 is in position. When sliding in the abutment groove 33, the slider 35 is driven to slide in the slide groove 34, and the slider 35 will abut the push rod 36, forcing the push rod 36 to push the locking block 37 to lock the wire passing through the sealing ring 315. The arc rod 2 313 passing through the locking blocks 37 can make the three groups of locking blocks 37 and the arc rod 2 313 shrink inward in proportion, and compress the arc spring 2 314. The locking blocks 37 and the arc rod 2 313 that shrink in proportion can fix wires of different square numbers. When the rotating disk 32 rotates, the inclined surface of the limiting ratchet 311 will abut the teeth of the ratchet gear disk 31, and be forced to compress the positioning spring 2 312. At the same time, the limiting ratchet 311 can fix the rotating disk 32 to avoid accidentally touching its reset and causing the locking block 37 to loosen.

[0027] When the electrical cabinet body 1 is lifted, the motor 8 is started so that the output shaft of the motor 8 drives the bevel gear 1 9 to drive the bevel gear 2 11 to rotate, so that the bevel gear 2 11 drives the lifting screw 12 to rotate through the rotating rod 10, so that the lifting screw 12 drives the threaded lifting block 13 to rise upward, and when the electrical cabinet body 1 is lifted, the wire in the sealing ring 315 will be pulled, and the wire wound on the winding roller 42 will also be pulled. At the same time, when the motor 8 rotates, the output shaft of the motor 8 will drive the transmission wheel 1 211 and through the transmission belt 1 212, The transmission rod 29 rotates, and the transmission rod 29 drives the large gear ring 22 to rotate through the small gear 210. When the large gear ring 22 rotates, the arc guide groove 27 provided on the inner side thereof will abut against the cylinder 226, thereby forcing the cylinder 226 to slide in the arc guide groove 27. After the large gear ring 22 rotates a certain distance, the cylinder 226 will slide into the concentric annular groove 25. After the cylinder 226 is in the concentric annular groove 25, the cylinder 226 will abut against the slope of the abutment ring 28, so that the cylinder 226 gradually moves toward the direction of the positioning rod 225 and the protective The second spring 227 of the protective part is compressed, and as the cylinder 226 gradually slides to the concentric annular groove 25, the arc block 218 is pulled up through the positioning rod 225, so that the transmission rod 29 on the surface of the arc block 218 slides in the limit groove 23, and at the same time, the linkage rod 217 is pulled, so that the linkage rod 217 pulls the linkage block 216, so that the spring 1 220 of the protective part is compressed, and the linkage block 216 first pulls up the narrower part in the middle of the rubber sealing sleeve 230 and no longer seals the wires passing through, and at the same time, the linkage block 216 pulls the hinged tilting rod 221 to tilt up, so that The anti-wear wheel 222 at the other end of the tilting rod 221 contacts the surface of the wire to prevent the wire from being excessively worn when the wire is pulled when the electrical cabinet body 1 is raised, thereby increasing the service life of the wire. When the electrical cabinet body 1 stops lifting, the motor 8 stops, and the large gear ring 22 stops rotating. The compressed protective part spring 220 will push the linkage block 216 to reset, so that the linkage block 216 pushes the narrower part in the middle of the rubber sealing sleeve 230 to continue to seal the wire, thereby preventing dust from entering the external junction box 21 when the electrical cabinet body 1 is used at the construction site.

[0028] When the wire is pulled and drives the winding roller 42 to rotate, the winding roller 42 first winds up the spiral spring 47, and at the same time, the winding roller 42 will drive the connecting rod 43 to rotate synchronously through the transmission wheel 2 44 and the transmission belt 2 45, and the connecting rod 43 will drive the reciprocating screw rod 48 to rotate. Since the screw sleeve 49 is penetrated by the reciprocating screw rod 48 and threadedly connected, and the guide ring 411 on the surface of the screw sleeve 49 penetrates the limiting rail 410, when the reciprocating screw rod 48 rotates, the guide ring 411 is located in the limiting rail 410 and slides back and forth, so that the wire wound on the winding roller 42 can be neatly wound on the winding roller 42 regardless of whether it is unwinding or winding, so as to avoid the wire on the winding roller 42 from getting entangled when the electrical cabinet body 1 is raised or lowered.

[0029] When the electrical cabinet body 1 is raised, the roller 15 will first be located in the roller groove 316 and roll, and at the same time the triangular block 14 will gradually contact the anti-skew wheel 319, so that the anti-skew wheel 319 will contact the U-shaped frame 317 and shrink into the fixed column 320 and compress the positioning part spring three 318; when the triangular block 14 exceeds the anti-skew wheel 319, the compressed positioning part spring three 318 will push the U-shaped frame 317 to reset the anti-skew wheel 319, so that the anti-skew wheel 319 will limit the pulled-up electric wires in the anti-skew wheel 319, so that the electric wires are offset between the electrical cabinet body 1 and the lifting frame 5 when the electrical cabinet body 1 is raised, ensuring that the electric cabinet body 1 can be stably used while the circuit can be stably used.

[0030] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
