Description

Technical Field

[0001] This utility model relates to the field of wire cutting technology, specifically to a wire cutting device for power relocation. Background Technology

[0002] Chinese patent document CN211161672U discloses a wire cutting device for power relocation. The device uses a fixing component to secure the wire, and then a motor is turned on by a first switch. The motor drives a first pulley to rotate, and the first pulley drives a threaded rod to rotate through a belt-connected transmission to a second pulley. The threaded rod then drives the cutting blade to descend and cut the wire through a threaded connection between the threaded rod and a lifting plate. This effectively avoids the need for manual cutting with pliers, which is not only labor-intensive, time-consuming, and inefficient, but also unsuitable for cables of different thicknesses.

[0003] In the above-mentioned scheme, a belt and pulley are usually used to drive the threaded rod to rotate, which in turn drives the lifting plate to move the shearing blade downward to cut the wire. However, when the wire is hard, the belt is prone to slipping on the surface of the pulley, resulting in transmission failure. In addition, the lifting plate is only connected to the threaded rod at one end through a threaded fit, while the other end moves in the groove by relying on a pulley. When cutting wires with high hardness, the lifting plate will be subjected to uneven load, causing the unconnected end to rise upward, which will cause the threaded rod to be subjected to additional bending moment. Long-term use will easily cause the threaded rod to bend and deform, affecting the transmission accuracy and equipment life. Utility Model Content

[0016] Example 1 like Figure 1 - As shown in the bidirectional lead screw 3, the power line cutting device for power relocation proposed in this utility model includes a housing 1, a cutting blade 5, a limiting plate 10, and an adjustment component; The shearing blade 5 is located in the middle of the inner side of the housing 1, and the outer side of the shearing blade 5 is covered with a mounting base for fixing the shearing blade 5 in use. There are two limiting plates 10. Both limiting plates 10 are set on the side of the mounting base and are symmetrically arranged according to the middle of the mounting base. The top of the limiting plate 10 is bent to the side to facilitate the placement of the wire between the two limiting plates 10. A pressing component is provided between the two limiting plates 10, which is connected to the mounting base and fixes the wire in use. The adjustment component is located at the top of the housing 1 and connected to the top of the mounting base. It is used to adjust the height of the mounting base during use and to make the mounting base drive the shearing blade 5 to adjust synchronously. When the mounting base drives the shearing blade 5 to move down, the shearing blade 5 cuts the wire between the two limit plates 10.

[0017] In this embodiment, the shearing blade 5 is fixed to one side of the middle between two limiting plates 10 by the mounting base. The wire is placed between the two limiting plates 10, and the part to be sheared is located directly below the shearing blade 5. The adjusting component is connected to the top of the mounting base and is used to drive the mounting base to move up and down. When the adjusting component drives the mounting base to move down, the pressing component first contacts the wire, and its bottom is elastically compressed, thereby pressing and fixing the wire tightly between the two limiting plates 10. The adjusting component also applies vertical downward pressure to the top of the mounting base, so that the shearing blade 5 completes the shearing with a larger shearing force, ensuring that the mounting base runs smoothly and avoiding the wire position from shifting during the shearing process. This further improves the shearing accuracy and operational reliability, and significantly improves the shearing strength and equipment service life.

[0018] Example 2 As shown in the figure, the bidirectional lead screw 3, the power line cutting device for power relocation proposed in this utility model, the difference between this embodiment and the first embodiment is that the mounting base includes a mounting plate 7, a tube body 16 and a bolt 17; The mounting plate 7 has a slot with an opening at the bottom in the middle, and the shearing blade 5 is located inside the slot. The slot and the shearing blade 5 are arranged to match the size of the slot. The tube body 16 passes through the mounting plate 7 and the shearing blade 5 and is inserted into one side of the shearing blade 5 and the mounting plate 7; Bolt 17 is installed inside the pipe body 16 and connected to the mounting plate 7.

[0019] In an optional embodiment, the length of the tube body 16 is less than the thickness of the mounting plate 7, in order to prevent the tube body 16 from moving on the shearing blade 5 and the mounting plate 7 when the two ends of the bolt 17 are connected to the ends of the tube body 16.

[0020] In an optional embodiment, a notch is provided at the bottom center of the side of the mounting plate 7. The width of the notch is adapted to the spacing between the two limiting plates 10. This notch is used to avoid the wire during use, so as to prevent the bottom of the mounting plate 7 from contacting the wire and causing the shearing blade 5 to be unable to perform the cutting work.

[0021] In this embodiment, the shearing blade 5 is placed inside the slot of the mounting plate 7, and the connecting rod 6 is placed on the mounting plate 7 through the shearing blade 5 and the mounting plate 7, so that the tube body 16 limits the position of the shearing blade 5 inside the slot, and the bolt 17 is placed inside the tube body 16 and connected to the mounting plate 7, so that the position of the tube body 16 is fixed and the tube body 16 is prevented from falling off during use.

[0022] Example 3 like Figure 1-2 As shown, the present invention proposes a power line cutting device for power relocation. Compared with the first embodiment, the difference in this embodiment is that the pressing component includes an extension plate 8, a slide bar 9, a pressure plate 11, and a spring 13. The extension plate 8 is installed on the top side of the mounting plate 7 and is located above the two limiting plates 10; The slide bar 9 is located in the middle of the extension plate 8 and extends to the bottom of the extension plate 8. When in use, the slide bar 9 can be set as a screw and threadedly connected to the extension plate 8. When in use, the slide bar 9 is rotated on the extension plate 8 to adjust the height of the pressure plate 11 so that the distance between the bottom end of the pressure plate 11 and the bottom inner side of the housing 1 matches the wire size so as to perform the pressing work on the wire. The limiting plate 10 is installed at the bottom end of the slide bar 9 and is located between the two limiting plates 10; Spring 13 is sleeved on the outside of slide bar 9 and located between limit plate 10 and extension plate 8.

[0023] In an optional embodiment, a soft pad 12 is provided at the bottom end of the limiting plate 10 to separate the limiting plate 10 from the wire during use, thereby reducing damage to the surface of the wire.

[0024] In this embodiment, the spring force of the spring 13 moves the pressure plate 11 downward below the extension plate 8, thus limiting the position of the slide rod 9 and the pressure plate 11. When the mounting plate 7 moves downward, the mounting plate 7 drives the extension plate 8 to move downward, so that the pressure plate 11 drives the soft pad 12 to contact the wire first, and the pressure plate 11 is forced to drive the slide rod 9 to move upward on the extension plate 8. The pressure plate 11 also drives the spring 13 to compress below the extension plate 8, so that the pressure plate 11 is subjected to the spring force of the spring 13, thereby pressing and fixing the wire between the two limiting plates 10 by the spring force, ensuring the stability of the wire during shearing.

[0025] Example 4 like Figure 1-2 As shown, the present invention proposes a power line cutting device for power relocation. Compared with the first embodiment, the difference in this embodiment is that the adjustment component includes a motor 2, a bidirectional lead screw 3, a connecting block 4, and a connecting rod 6. The bidirectional lead screw 3 is rotatably mounted on the top of the housing 1; There are two connecting blocks 4. The two connecting blocks 4 are respectively threaded to one end of the bidirectional lead screw 3, and their top ends are slidably connected to the top end of the inner side of the housing 1. The connecting rod 6 is rotatably mounted on the bottom end of the connecting block 4 and rotatably connected to the mounting plate 7; The motor 2 is located on one side of the housing 1 and is connected to the bidirectional lead screw 3. The end of the motor 2 has a reduction structure, and the motor 2 is connected to the bidirectional lead screw 3 through the reduction structure.

[0026] In an optional embodiment, a slide rail 15 is provided on the inner top of the housing 1, and a slide groove 14 is provided on the top of the connecting block 4. When the connecting block 4 and the housing 1 are installed together, the slide rail 15 is accommodated in the slide groove 14. This is used to limit the connecting block 4 during use and to support the connecting block 4. This allows the housing 1 and the slide rail 15 to be subjected to force when the connecting block 4 moves, thereby reducing the stress on the bidirectional lead screw 3 and improving the service life of the equipment.

[0027] In this embodiment, the motor 2 drives the bidirectional lead screw 3 to rotate, and the housing 1 and slide rail 15 simultaneously limit the connection block 4, so that the two connection blocks 4 move relative to each other on the bidirectional lead screw 3. This causes the connection block 4 to drive the top end of the connection rod 6 to move, so that the two ends of the connection rod 6 rotate at the bottom end of the connection block 4 and the top end of the mounting plate 7. This causes the two connection blocks 4 to apply vertical pressure to the top end of the mounting plate 7 through the connection rod 6, so that the mounting plate 7 drives the shearing blade 5 to cut the wire.

[0028] In this invention, the shearing blade 5 is installed inside the mounting plate 7 by the cooperation of the tube body 16 and the bolt 17, and the wire is placed between the two limiting plates 10, with the part to be sheared located directly below the shearing blade 5. The motor 2 is started to drive the bidirectional lead screw 3 to rotate, and the connecting block 4 is simultaneously limited by the housing 1 and the slide rail 15, so that the two connecting blocks 4 move relative to each other on the bidirectional lead screw 3. This causes the connecting blocks 4 to drive the top end of the connecting rod 6 to move, so that the two ends of the connecting rod 6 rotate at the bottom end of the connecting block 4 and the top end of the mounting plate 7. This allows the two connecting blocks 4 to move relative to the mounting plate 7 through the connecting rod 6. Vertical pressure is applied to the top, causing the mounting plate 7 to move the shearing blade 5 downward to cut the wire. As the mounting plate 7 moves the shearing blade 5 downward, the mounting plate 7, in cooperation with the extension plate 8, causes the pressure plate 11 to move the soft pad 12 into contact with the wire. The pressure plate 11 is then forced to move the slide rod 9 upward on the extension plate 8, and the pressure plate 11 causes the spring 13 to compress below the extension plate 8. The pressure plate 11 is then subjected to the elastic force of the spring 13, which in turn presses and fixes the wire between the two limiting plates 10, ensuring the stability of the wire during cutting and significantly improving the cutting strength and service life of the equipment.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
