Description
Technical Field
[0001] The invention relates to the technical field of wiring devices, in particular to a wiring device for a power transformer. Background Art
[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are primary coils, secondary coils, and magnetic cores. In electrical equipment and wireless circuits, it is often used to increase or decrease voltage, match impedance, and provide safety isolation. In a generator, whether the coil moves through a magnetic field or the magnetic field moves through a fixed coil, an electric potential can be induced in the coil. When wiring wires, the existing power transformer wiring device requires that two sections of wires be connected so that current can pass smoothly. When wiring, the ends of the wires need to be butted, and the ends of the two sections of wires need to be pulled apart. After the two ends of the line are transported to the middle position of the wiring device, the two sections of wires are connected using a connecting mechanism so that current can pass through, thus completing the wiring. However, during the wiring process, since the wires contain a large amount of current, it is very dangerous to strip the wires, and the thick insulating clothing worn by the workers will also affect the workers' wiring operations.
[0003] The existing patent (publication number: CN117393284A) discloses a high-voltage wiring device for a power transformer, which relates to the technical field of wiring of power transformers, and includes: a mounting frame and an upper wire clamp, the inner surface of the mounting frame is fixedly connected with a lower wire clamp, the inner surface of the mounting frame is fixedly connected with a fixing plate near the upper surface of the lower wire clamp, the outer surface of the lower wire clamp adjacent to the upper wire clamp is symmetrically provided with wire grooves, the outer surfaces of both sides of the mounting frame are fixedly connected with threading brackets, the upper surface of the threading bracket is fixedly connected with a turntable, and the end surface of the turntable slides through the threading bracket and extends to the inside. This high-voltage wiring device for a power transformer, when the power transformer is used to perform wiring operations on the high-voltage wire, the high-voltage wire is inserted into the inner side of the threading bracket through the through hole position, and the purpose of automatically completing the stripping operation of the high-voltage wire is achieved through the coordinated use of the wire feeding assembly, the skinning assembly and the cutting assembly, and the occurrence of safety accidents is effectively avoided. The existing technology has the following problems: 1. When the existing wiring device is in use, the two sections of the line are stripped and then transported between the upper and lower wire clamps, and the upper and lower wire clamps are used to clamp the two sections of the wire. The wire clamps are conductors, so as to connect the lines to complete the wiring. However, this connection method is unstable. When the wires are subjected to axial force, they are prone to loosening and failure. Summary of the invention

[0035] In this embodiment, Figure 12-13 As shown, two fixed plates 901 are provided, and the inclined guide grooves 902 on the two fixed plates 901 are staggered, and the top surfaces of the two fixed plates 901 are both in contact with the bottom surface of the movable plate 907, and a connecting plate 9010 is fixedly connected between the movable plates 907; the connecting plate 9010 connects the two movable plates 907 as a whole to ensure the synchronous movement of the two movable plates 907, and the staggered distribution of the inclined guide grooves 902 can make the wire clamps 904 under the two movable plates 907 also staggered when clamping the cables. In a top-down perspective, the cables can be clamped in a wavy shape. Compared with the traditional upper and lower direct clamping method, this clamping method is more stable, the cables are not easy to loosen, and the clamping effect is better.
[0036] In this embodiment, Figure 3 and Figure 7-8As shown, the ring cutting assembly 13 includes a connecting rope 1301 fixedly connected to one side of the delay block 9012, the end of the connecting rope 1301 away from the delay block 9012 is fixedly connected to a swing rod 1302, the top of the swing rod 1302 away from the connecting rope 1 1301 is fixedly connected to a connecting rope 2 1303, the middle part of the top of the swing rod 1302 is hinged with a supporting link 1304, the bottom end of the supporting link 1304 is hinged with an I-shaped slider 1305, the I-shaped slider 1305 is slidably connected to the middle part of the adaptation groove 1306, the adaptation groove 1306 is provided in the middle part of the lifting plate 1307, the bottom surface of the lifting plate 1307 is hinged with shearing links 1308 on both sides, and the bottom of the shearing link 1308 is hinged. The end is hinged to the middle part of the outer side of the semicircular frame 1309, and the inner circle of the semicircular frame 1309 is fixed with a ring cutting knife 1310 by a spring. One side of the semicircular frame 1309 is rotatably connected to one side of the L-shaped mounting rod 1311 through a connecting shaft, and the bottom end of the swing rod 1302 is hinged to the top end of the L-shaped mounting rod 1311; when the connecting plate 9010 moves toward the direction of the riveted sheet 5, the swing rod 1302 will be pulled by the connecting rope 1301 to rotate with the hinge point at its bottom end as the fulcrum, and when the swing rod 1302 is pulled by the connecting rope 1301, it will rotate toward the side of the clamping cavity 4. At this time, the swing rod 1302 will pull the connecting rope 2 1303 to move, and the connecting rope 2 1303 will be used to pull the connecting rope 1303 to move. 03 The active belt in the conveying component 6 is pulled upward to separate the active belt from the surface of the cable in the conveying channel 601, and the conveying of the cable is stopped. In addition, during the rotation of the swing rod 1302 toward the side of the clamping cavity 4, the top of the swing rod 1302 will change in height. The swing rod 1302 drives the I-shaped slider 1305 to slide along the adaptation groove 1306 toward the clamping cavity 4 through the supporting connecting rod 1304. At the same time, the I-shaped slider 1305 will also change in height. The I-shaped slider 1305 will push the lifting plate 1307 to move downward. The downward movement of the lifting plate 1307 will push the semicircular frame 1309 to move through the two shear connecting rods 1308. The connecting shaft is rotatably installed on the L-shaped mounting rod 1311, so the two semicircular frames 1309 at this time will rotate with the connecting shaft on the L-shaped mounting rod 1311 as the axis, and finally the bottom ends of the two semicircular frames 1309 will fit together to form a complete circle, and under the internal spring pressure of the semicircular frame 1309, the circular cutting knife 1310 is pushed into the insulation skin of the cable to cut off the outer skin of the cable, so that the insulation skin falls to the bottom of the conveying and cutting chamber 3 and can be taken out by the workers. A limiting bevel block is also provided on the top of the conveying channel 601 on the right side of the swing rod 1302, and the limiting bevel block is inclined toward the direction of the clamping chamber 4. The limiting bevel block can prevent the swing rod 1302 from rotating to a state perpendicular to the bottom surface and forming a dead point.

The L-shaped mounting rod 1311 is welded to one end of the conveying channel 601, and the end of the connecting rope 1303 away from the swing rod 1302 is connected to the top surface of the outer shell of the conveyor belt 603; when the connecting plate 9010 moves toward the riveting plate 5, the delay block 9012 will first slide along the inside of the delay groove 9011 toward the direction of the circular cutting knife 1310. At this time, the connecting plate 9010 will not apply tension to the connecting rope 1301. When the delay block When 9012 moves to the rightmost end inside the delay groove 9011, the connecting plate 9010 will pull the delay block 9012, and finally drive the circumcision component 13 to circumcise the cable outer skin. At the same time, the circumcision component 13 will also pull the active belt up and separate from the cable through the connecting rope 1303. The function of this structure is that the up and down movement of the active belt is smaller than the movement of the connecting plate 9010. In order to avoid the active belt from being separated from the cable too early, resulting in the cable not being delivered in place, the delay block 9012 and the delay groove 9011 are set to delay the timing of the active belt separating from the cable.
[0038] In this embodiment, Figure 4 , Figure 5 and Figure 8-9 As shown, the conveying assembly 6 includes a conveying channel 601 fixedly connected to the bottom of the inner side of the conveying cutting chamber 3, the inner wall of the conveying channel 601 is fixedly connected with three groups of damping springs 602, one end of the three groups of damping springs 602 away from the inner wall of the conveying channel 601 is fixedly connected with a conveying belt 603, a rectangular plate 604 is welded on the side of the top plate of the conveying belt 603 close to the clamping chamber 4, one side of the rectangular plate 604 is fixedly connected with an adaptive spring 605, one end of the adaptive spring 605 away from the rectangular plate 604 is fixedly connected with a floating plate 606, and the floating plate 606 is away from the side of the adaptive spring 605 A longitudinal cutting knife 607 is provided; when the cable needs to be transported, the cable is first inserted into the transport channel 601, and under the action of the damping spring 602, the three groups of conveyor belts 603 will clamp the cable in the middle, and the conveyor belt 603 is driven to rotate by repeatedly pulling the pull rod 7 to transport the cable into the clamping cavity 4, and when the end of the cable moves to the end of the conveyor belt 603, it will contact the longitudinal cutting knife 607, and under the action of the adaptive spring 605, the floating plate 606 will be squeezed towards the cable, and the floating plate 606 will drive the longitudinal cutting knife 607 to cut the cable insulation into three equal parts.
[0039] In this embodiment, Figure 4 , Figure 5 and Figure 8-9As shown, the conveyor belt 603 is divided into a driving belt and two driven belts, wherein the longitudinal cutting knife 607 at the end of the driving belt has an arc structure on both sides, while the longitudinal cutting knife 607 at the end of the driven belt has an arc structure on one side close to the driving belt and a flat structure on the other side, and the longitudinal cutting knife 607 at the end close to the conveyor belt 603 has a rounded corner design; the longitudinal cutting knife 607 with a rounded corner design can prevent the cable end from getting stuck when it contacts the longitudinal cutting knife 607, and the side of the arc structure can guide the cut insulation skin away from the central axis of the cable. Because the insulation skin is cut into three equal parts, the two insulation skins located at the top will spread out in a trumpet shape along the arc edge and pass through the middle of the two semicircular frames 1309, and then the insulation skin will be blocked by the baffle 10 to prevent the two groups of insulation skin from entering the inside of the clamping cavity 4, and located directly below the cable The insulating skin is not guided by the curved edge, and because the outer skin and the cable are in close contact for a long time, the outer wall directly below is not guided at this time, so it will continue to fit the cable and enter the clamping cavity 4 together, and will not fall to the outside of the two semicircular frames 1309. After the cable is fixed, the ring cutting component 13 will cut it off together with the other two groups of insulating skins, and it will fall into the conveying cutting cavity 3 and be taken out by the worker. The active belt is composed of an outer shell, three rollers and a conveyor belt, while the driven belt lacks a conveyor belt compared to the active belt, and the three rollers of the driven belt are all driven rollers, without power input, and the two ends of the rollers in the active belt closest to the clamping cavity 4 are connected to the drive shaft 704 in the pull rod 7, and manually pulling the pull rod 7 can provide power to the conveying component 6, thereby conveying and clamping the cable into the clamping cavity 4.

The rotation of the transmission gear 1102 will drive the upper meshing upper tooth plate 1103 to move in the opposite direction of the lower tooth plate 1101. The upper tooth plate 1103 will drive the connecting beam 1105 to move toward one side of the conveying cutting chamber 3 through the U-shaped plate 1104. The connecting beam 1105 drives the winding gear 803 to mesh with the cylindrical gear 805, thereby linking the winding assembly 8 and the pull rod 7.

When the pull rod 7 rotates in the direction of the clamping chamber 4, the pawl 2 702 will not drive the ratchet wheel 2 703 to rotate, and the driving shaft 704 will not rotate at this time. On the contrary, when the rotation direction of the pull rod 7 is opposite, the pawl 2 702 will drive the ratchet wheel 2 703 to rotate, thereby driving the driving shaft 704 to rotate, providing power for the winding component 8 and the conveying component 6.
[0044] The use method and advantages of the present invention: When the power transformer wiring device is used, the working process is as follows:
[0045] First, use the rivet sheet 5 and fasteners to install the wiring device on the wiring terminal of the transformer 2, and then insert the cable end that needs to be clamped into the middle of the conveying channel 601. At this time, under the action of the damping spring 602, the three conveyor belts 603 will squeeze the cable in the middle, and the end of the conveyor belt 603 close to the outside of the conveying channel 601 is inclined to facilitate the insertion of the cable. After the cable is inserted, repeatedly pull the pull rod 7 to drive the drive shaft 704 to rotate. The drive shaft 704 will eventually drive the cylindrical gear 805 to idle through the main bevel gear 808. At the same time, the drive shaft 704 will drive the conveyor belt on the active belt to rotate and transport the cable toward the clamping cavity 4. During the transportation process, the cable sheath will be cut open by the longitudinal cutting knife 607, and the cut cable sheath will be temporarily blocked by the baffle 10 outside the clamping cavity 4, and the cable body will continue to be transported to the inside of the clamping cavity 4. Subsequently, the cable end will contact the movable push plate 12, and the movable push plate 12 will drive the connection in the transmission assembly 11 The crossbeam 1105 pushes the winding gear 803 to mesh with the cylindrical gear 805. At this time, the winding assembly 8 will wind up the traction rope 8013, and the traction rope 8013 pulls the movable plate 907 to move toward the direction of the riveting plate 5 through the connecting plate 9010. At this time, the wire clamp 904 under the movable plate 907 clamps the cable in an inclined and dislocated manner. The inclined and dislocated clamping method is more stable and can also prevent the cable from retreating, fix it in the clamping cavity 4 to complete the clamping, and the traction rope 8 013 In the process of pulling the connecting plate 9010, the connecting plate 9010 will drive the cutting assembly 13 to cut off the outer sheath of the cable through the connecting rope 1 1301. At the same time, the connecting rope 2 1303 in the cutting assembly 13 pulls the conveyor belt 603 upward, so that the active belt in the conveyor belt 603 is separated from the cable, and the transportation of the cable is stopped. The winding assembly 8 is also provided with a ratchet 809 and a pawl 8010 that cooperate with each other, which can prevent the winding wheel 804 from rotating and causing the wire clamp 904 to loosen.
