Description

Technical Field

[0001] The present invention relates to the technical field of electrical automation, in particular to a wire bridge for electrical automation. Background Art

[0002] Electrical automation is an engineering technology field involving multiple disciplines such as power electronics, motors, automatic control, and computers. Its main goal is to achieve automated control and optimization of power systems. It is widely used in industry, agriculture, transportation, medical care, military and other fields. From the automated control of factory production lines to the automated management of smart homes, they are inseparable from the support of electrical automation. It is an important support for the development of modern society. In the electrical automation system, wire trays, as an important electrical accessory, play an indispensable role, especially in occasions that require a large amount of wire wiring, such as factory workshops, data centers, commercial buildings, etc. Wire trays can protect wires and cables from the invasion of the external environment and reduce cable damage caused by environmental factors.

[0003] At present, when laying wires on a bridge, there is a lack of clear layers or partitions inside the bridge, which leads to a lack of clear partitions when laying the wires. As a result, the wires are easily mixed, crossed, overlapped, etc. during the laying process, resulting in messy and dense wires. When the wires are dense and scattered, the gaps between the wires are reduced, which makes it difficult to conduct heat between the wires, resulting in poor heat dissipation between the wires, thereby accelerating the aging of the wire insulation layer and shortening the service life of the wires.

[0021] See also Figure 1 、 Figure 10 、 Figure 12 、 Figure 13 ,and Figure 14 As shown, the purpose of this embodiment is to provide a wire bridge for electrical automation, including a bridge body 1, two pairs of support plates 2 are symmetrically fixedly connected to the inner side of the bridge body 1, and the inner walls of the multiple support plates 2 are fixedly connected with tension springs 3, and a cross plate 4 is fixedly connected between the ends of the multiple tension springs 3, and the outer wall of the cross plate 4 is slidably connected to the inner wall of the bridge body 1, and two limiting slide rails 401 are symmetrically fixedly connected to the lower surface of the cross plate 4, and two limiting slide grooves 402 are symmetrically opened on the lower surface of the cross plate 4 between the ends of the two limiting slide rails 401, and a guide groove 403 is opened on the inner wall of the cross plate 4, and a plurality of heat dissipation holes 404 are opened on the inner side of the cross plate 4 near both sides of the guide groove 403, and a plurality of clamping components 5 are provided inside the bridge body 1 below the cross plate 4; The clamping assembly 5 includes an annular seat A501 and an annular seat B502. A plurality of connecting plates 503 are fixedly connected between the outer walls of the annular seats A501 and the annular seats B502. A plurality of limiting grooves A504 are provided on the inner walls of the annular seat A501 and the annular seat B502. An annular groove 505 is provided on the inner wall of the annular seat A501. A rotating gear ring 506 is rotatably connected to the inner wall of the annular groove 505. The teeth of the rotating gear ring 506 are meshed with a plurality of gears 507.

The gears 507 are engaged with each other, thereby driving the multiple gears 507 to rotate synchronously. Then, when the gears 507 rotate, they mesh with the multiple racks 508, so that the multiple racks 508 can be synchronously moved toward the inner side of the annular seat B502. Then, the multiple racks 508 can use the arc seat 510 to make the arc plate 512 clamp the wires. When the arc plate 512 clamps the wires, the elastic force of the supporting spring A511 makes the arc plate 512 generate different clamping forces according to the thickness of the wires when clamping the wires, thereby increasing the application range of the clamping component 5.

[0023] In this embodiment, Figure 2 、 Figure 3 、 Figure 5 and Figure 7As shown, both sides of the bridge body 1 are provided with limited slideways B6, and the inner walls of the two limited slideways B6 are slidably connected with support sliders 601, and the inner walls of the two support sliders 601 are rotatably connected with threaded connecting rods 602, and the ends of the two threaded connecting rods 602 are fixedly connected with a gripping rod 603, and the other end of one of the threaded connecting rods 602 is fixedly connected with a knob 6031, and the outer walls of the two threaded connecting rods 602 are threadedly connected with connecting pieces 604, and the ends of the two connecting pieces 604 are hinged with adjusting rods 605, and a connecting block 606 is hinged between the ends of the two adjusting rods 605, and the outer side of the connecting block 606 is slidably connected to the inner side of the guide groove 403; the outer sides of the multiple annular seats A501 are respectively fixedly connected with T-shaped sliders 7 and L-shaped connecting frames 8, and the outer sides of the multiple T-shaped sliders 7 are slidably connected with cross frames 701, Both ends of the horizontal frame 701 are slidably connected to the limit seats 7011, and the outer sides of the two limit seats 7011 are fixedly connected to the inner side of the bridge frame body 1. The outer side of the horizontal frame 701 is slidably connected to multiple vertical frames 702, and the outer sides of the multiple vertical frames 702 are fixedly connected to the horizontal slide 703. The inner wall of the horizontal slide 703 is slidably connected to the outer wall of the two limit slide rails 401, and the upper surface of the horizontal slide 703 is fixedly connected to the lower surface of the connecting block 606, and the lower surface of the horizontal slide 703 is symmetrically provided with two limit grooves B704, and the inner sides of the two limit grooves B704 are slidably connected to the hinge blocks 705, and the outer sides of the multiple hinge blocks 705 are hinged with hinge plates 706, and the ends of the multiple hinge plates 706 are hinged with rotating columns 707, and the outer walls of the multiple rotating columns 707 are respectively hinged to the outer sides of multiple hinges 509.

[0024] In this embodiment, when it is necessary to lay the wires inside the bridge body 1, the two threaded connecting rods 602 are rotated synchronously by turning the knob 6031. While the two threaded connecting rods 602 are rotating, the two connecting members 604 are threadedly engaged with the two connecting members 604, so that the two connecting members 604 are synchronously moved toward the two ends of the grip rod 603. When the two connecting members 604 are approaching, the adjusting rod 605 pushes the cross plate 4 and the cross slide 703 to move downward synchronously through the connecting block 606. At the same time, the cross frame 701 will not move downward synchronously due to the support of the limit seat. When the cross slide 703 moves downward, it will synchronously drive the hinge block 705 to move downward synchronously. When the hinge block 705 moves downward, it will cause force between the multiple hinge plates 706, and through the sliding cooperation between the limit slot B704 and the multiple hinge blocks 705, the The angles between the multiple hinged plates 706 can be expanded, and at the same time, the hinged plates 706 can apply force through the hinged parts 509 of the rotating column 707, so that the hinged parts 509 can adjust the spacing between the clamping components 5 in proportion to the angle of the hinged plates 706 while the hinged parts 509 change, so that the layout of the wires inside the bridge body 1 can be made more regular and orderly, and the occurrence of chaotic crossing can be reduced. At the same time, by adjusting the spacing between the wires, the heat dissipation holes 404 opened on the horizontal plate 4 above the clamping components 5 increase the air flow space between the wires inside the bridge body 1, thereby preventing poor heat dissipation. Subsequently, when the spacing between the clamping components 5 is adjusted, as the horizontal slide 703 continues to move downward, the hinged parts 509 will be forced to push one of the racks 508 downward, thereby promoting the clamping component 5 to complete the clamping of the wires.

[0025] In this embodiment, Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 11As shown, two baffles 9 are symmetrically provided on the lower surface of the inner side of the bridge body 1, and a plurality of bottom plates 901 are slidably connected between the inner sides of the two baffles 9, and the inner walls of the plurality of bottom plates 901 are provided with limiting grooves C902, and the inner sides of the plurality of limiting grooves C902 are respectively slidably connected to the outer sides of the plurality of L-shaped connecting frames 8, and one end close to the limiting groove C902 is fixedly connected to the upper surface of the bottom plate 901, and the inner sides of the support frames A903 are rotatably connected to the rollers A904, and a plurality of support frames B905 are provided above the plurality of rollers A904, and the upper ends of the plurality of support frames B905 are slidably connected to the inner side of one of the limiting sliding grooves 402; wherein one side of the plurality of support frames B905 is An L-shaped slide 10 is fixedly connected, and the outer sides of the other ends of multiple L-shaped slides 10 are slidably connected to the inner side of another limiting slide 402, and the inner sides of multiple L-shaped slides 10 are slidably connected to slides 11, and the inner sides of multiple slides 11 are respectively fixedly connected to the outer sides of multiple rotating columns 707; the inner walls of multiple support frames B905 are symmetrically provided with two mounting grooves A12, the inner sides of the two mounting grooves A12 are slidably connected to support blocks 1201, and rollers B1202 are rotatably connected between the inner walls of the two support blocks 1201, and the upper surfaces of the two support blocks 1201 are fixedly connected to memory springs 1203, and the ends of the memory springs 1203 are fixedly connected to the inner walls of the mounting grooves A12.

[0026] In this embodiment, while the clamping assembly 5 is performing proportional spacing adjustment, the slide plate 11 and the L-shaped connecting frame 8 will apply force to the L-shaped slide 10 and the base plate 901 respectively, so that the base plate 901 and the L-shaped slide 10 can be adjusted synchronously with the spacing adjustment of the clamping assembly 5, and then the support frame A903 and the support frame B905 can respectively drive the roller A904 and the roller B1202 to adjust synchronously, so that the roller A904 and the roller B1202 can always correspond to the center of the annular slide B, and then by pushing the handle 603, the connecting block 606 is moved through the horizontal slide 703, and the horizontal slide 703 will drive the horizontal frame 701 to move synchronously through the vertical frame 702 while moving, and then through the movement of the horizontal frame 701, multiple clamping assemblies 5 can be driven to move synchronously, thereby completing the electric The laying of the wires is carried out, and the rolling friction of the wires on the roller A904 replaces the direct sliding friction between the wires and the inner side of the bridge body 1 during the laying process, thereby reducing the wear of the surface of the wires during the laying process, thereby increasing the service life of the wires. At the same time, the horizontal plate 4 slides down, so that the roller B1202 can approach the roller A904, thereby squeezing the wires running on the roller A904, thereby increasing the tension of the wires during laying, and further avoiding the phenomenon of the cables being entangled and crossed due to looseness during the laying process. At the same time, in the process of roller A904 and roller B1202 squeezing the wires, the buffering force generated by the memory spring 1203 is used to avoid the situation where roller A904 and roller B1202 cause damage to the wires due to excessive pressure when increasing the tension of the wires.

[0028] In this embodiment, by pressing down the two clamping parts 1405 synchronously, the extension rod 1404 drives the top block 1401 to move downward on the inner side of the installation groove B13 synchronously through the sleeve rod 1403, and the top block 1401 causes the support spring B14 to be compressed when moving downward, and drives the clamping column 1402 to move downward along the inner side B of the installation groove B13 synchronously, so that the clamping column 1402 is separated from the slot hole 1301, and when the clamping part 1405 is pressed down to correspond to the notch of the positioning groove 1302, the extension rod 1404 and the sleeve rod 1403 are contracted by pushing the clamping part 1405, so that the outer side of the clamping part 1405 is engaged with the inner side of the positioning groove 1302, thereby fixing the state of the top block 1401 after being pressed down, and then the cover plate 15 and The sliding between the limiting slides A101 enables the cover plate 15 to cover the bridge body. When the cover plate 15 and the bridge body 1 are completely covered, the clamping member 1405 is disengaged from the positioning groove 1302 by pulling the clamping member 1405, and then the top block 1401 is quickly pushed up by the tension of the support spring B14, so that the top block 1401 simultaneously pushes the clamping column 1402 to rise, so that the outer side of the clamping column 1402 is engaged with the inner side of the limiting clamping groove 1501, and thus the covering connection state between the cover plate 15 and the bridge body 1 can be fixed, so that the disassembly and assembly function between the cover plate 15 and the bridge body is more convenient, and then the disassembly and assembly between the cover plate 15 and the bridge body 1 can be conveniently achieved, thereby achieving the purpose of facilitating the inspection of the interior of the bridge body 1.

[0029] In summary, the working principle of the present invention is as follows: When it is necessary to lay wires inside the bridge body 1, first, the wires to be laid are placed in the inner side of the annular slide B one by one, supported and lifted by the arc plate 512, and then the two threaded connecting rods 602 are rotated synchronously by turning the knob 6031. While the two threaded connecting rods 602 are rotating, they cooperate with the threads between the two connecting pieces 604, so that the two connecting pieces 604 are synchronously moved toward the two ends of the gripping rod 603, and while the two connecting pieces 604 are moving closer, the adjusting rod 605 pushes the horizontal plate 4 and the horizontal slide 703 to move downward synchronously through the connecting block 606, and at the same time, the horizontal frame 701 will not move downward synchronously due to the support of the limit seat, but will move horizontally. When the slide 703 moves downward, it will synchronously drive the hinge block 705 to move downward, and when the hinge block 705 moves downward, it will cause a force to be applied between the multiple hinge plates 706, and through the sliding cooperation between the limit slot B704 and the multiple hinge blocks 705, the angles between the multiple hinge plates 706 can be expanded, and at the same time, the hinge plates 706 can apply force to the hinge parts 509 through the rotating column 707, so that the hinge parts 509 can adjust the spacing between the clamping components 5 in proportion to the change of the angle of the hinge plates 706, so that the layout of the wires inside the bridge body 1 can be more regular and orderly, and the occurrence of chaotic crossing can be reduced. At the same time, by adjusting the spacing between the wires, the horizontal clamping components 5 above The heat dissipation holes 404 opened on the plate 4 increase the air flow space between the wires inside the bridge body 1, thereby preventing poor heat dissipation. Subsequently, when the spacing between the clamping components 5 is adjusted, as the horizontal slide 703 continues to move downward, the hinge 509 is forced to push one of the racks 508 to move downward, and then one of the racks 508 is engaged with one of the gears 507 during the downward movement, so that one of the gears 507 rotates, and during the rotation process, one of the gears 507 engages with the teeth of the rotating gear ring 506 through the outer edge, thereby driving the rotating gear ring 506 to rotate synchronously, and when the rotating gear ring 506 rotates, it engages with the remaining multiple wheels, thereby driving multiple gears. The wheels 507 rotate synchronously, and then the multiple gears 507 rotate, and then the multiple racks 508 are meshed with each other, so that the multiple racks 508 can be synchronously moved toward the inner side of the annular seat B502, and then the multiple racks 508 are all clamped to the wires by the arc seat 510. When the arc plate 512 clamps the wires, the elastic force of the supporting spring A511 enables the arc plate 512 to generate different clamping forces according to the thickness of the wires, thereby increasing the application range of the clamping component 5. In addition, when the clamping component 5 performs the proportional spacing adjustment work, the slide plate 11 and the L-shaped connecting frame 8 will apply force to the L-shaped slide seat 10 and the bottom plate 901 respectively.The bottom plate 901 and the L-shaped slide 10 can be adjusted synchronously with the spacing adjustment of the clamping assembly 5, so that the support frame A903 and the support frame B905 can respectively drive the roller A904 and the roller B1202 to adjust synchronously, so that the roller A904 and the roller B1202 can always correspond to the center of the annular slide B, and then by pushing the grip 603, the connecting block 606 is moved through the horizontal slide 703, and the horizontal slide 703 will drive the horizontal frame 701 to move synchronously through the vertical frame 702 when moving, and then through the movement of the horizontal frame 701, it can synchronously drive multiple clamping assemblies 5 to move, thereby completing the laying of the wires, and the rolling friction of the wires on the roller A904 is replaced During the laying process, the wires directly slide against the inner side of the bridge body 1, thereby reducing the wear of the wire surface during the laying process, thereby increasing the service life of the wires. At the same time, the horizontal plate 4 slides down, allowing the roller B1202 to approach the roller A904, thereby squeezing the wires running on the roller A904, thereby increasing the tension of the wires during laying, and further avoiding the phenomenon of the wires being entangled and crossed due to looseness during the laying process. At the same time, in the process of rollers A904 and B1202 squeezing the wires, the buffering force generated by the memory spring 1203 is used to avoid the rollers A904 and B1202 from causing damage to the wires due to excessive pressure when increasing the tension of the wires. In order to prevent the line from being damaged, the two clamping parts 1405 are pressed down synchronously, so that the extension rod 1404 drives the top block 1401 downward on the inner side of the installation groove B13 through the sleeve rod 1403. When the top block 1401 moves downward, the support spring B14 is compressed, and the clamping column 1402 is driven to move downward along the inner side B of the installation groove B13 synchronously, so that the clamping column 1402 is separated from the slot 1301. When the clamping part 1405 is pressed down to correspond to the notch of the positioning groove 1302, the extension rod 1404 and the sleeve rod 1403 are contracted by pushing the clamping part 1405, so that the outer side of the clamping part 1405 is engaged with the inner side of the positioning groove 1302, thereby fixing the state of the top block 1401 after being pressed down. The cover 15 is fixed, and then the cover 15 slides with the limiting slideway A101, so that the cover 15 can cover the bridge body. When the cover 15 and the bridge body 1 are completely covered, the clamping member 1405 is disengaged from the positioning groove 1302 by pulling the clamping member 1405, and then the top block 1401 is quickly pushed up by the tension of the support spring B14, so that the top block 1401 synchronously pushes the card column 1402 to rise, so that the outer side of the card column 1402 is engaged with the inner side of the limiting card groove 1501, and thus the covering connection state between the cover 15 and the bridge body 1 can be fixed, so that the disassembly and assembly function between the cover 15 and the bridge body is more convenient, and then the disassembly and assembly between the cover 15 and the bridge body 1 can be convenient.This makes it easier to inspect the interior of the bridge body 1.
