Description

Technical Field

[0001] This utility model belongs to the field of current transformer technology, and specifically relates to an adjustable spacing current transformer winding cable assembly. Background Technology

[0002] Current transformers are electrical devices that work based on the principle of electromagnetic induction. Their core function is to convert a large primary current into a small secondary current in proportion, thereby achieving measurement, protection and electrical isolation. During the production of current transformers, a winding cable guide is needed when winding the wire group.

[0003] Existing winding guides typically operate by driving a winding roller to rotate, which in turn moves a guide wheel. The rotating roller winds the cable around its surface, completing the winding process. However, this method has several drawbacks. For example, the distance between the rotating device and the guide wheel cannot be effectively adjusted. If the roller rotates too slowly, the cable may become loose or tangled. To address these issues, we propose an adjustable-distance current transformer winding guide. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable spacing current transformer winding guide, which has the advantage of effectively adjusting the spacing between the winding roller and the winding wheel, thereby improving the winding efficiency.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an adjustable spacing current transformer winding cable arranger, including a cable arranger body and an adjusting shell. Bearing plates are welded to both sides of the top of the cable arranger body. A cable arrangement device is bolted to the inner side of the bearing plate. A controller is bolted to the right side of the bearing plate. A hand crank is movably connected to the surface of the adjusting shell. A threaded rod is welded to the back of the hand crank. A threaded sleeve is threadedly connected to the surface of the threaded rod. A protective shell is bolted to the surface of the threaded sleeve. A motor is bolted to the inner cavity of the protective shell. A rotating rod is bolted to the left side of the motor. A wire roller is bolted to the left side of the rotating rod, extending through to the outside of the protective shell.

[0006] The above technical solution allows for easy adjustment of the distance between the protective shell and the winding equipment via a hand crank, threaded rod, and threaded sleeve, thereby improving the accuracy and stability of winding. The motor and rotating rod facilitate the rotation of the winding rollers to complete the winding process.

[0007] The present invention is further configured such that a housing is bolted to the inner side of the bearing plate, a cylinder is bolted to the center of the bottom of the housing cavity, a push plate is bolted to the top of the cylinder, a connecting block is bolted to the surface of the push plate, and the surface of the connecting block is bolted to the back of the adjusting shell.

[0008] The above technical solution allows for easy adjustment of the height of the wire roller through the use of cylinders, push plates, and connecting blocks, thereby reducing the stretching length of the wound cable and improving winding efficiency.

[0009] The present invention is further configured such that slide rails are welded to both sides of the inner cavity of the housing, and both sides of the push plate are slidably connected to the inner cavity of the slide rails.

[0010] The above technical solution improves the stability of the sliding plate by using a slide rail.

[0011] The present invention is further configured such that a sliding groove is provided on the other side of the bearing plate, and a sliding plate is slidably connected to the surface of the sliding groove.

[0012] The above technical solution improves the stability of the skateboard's sliding by using a sliding groove.

[0013] The present invention is further configured such that a groove is formed on the surface of the slide plate, and a slider is slidably connected to the inner cavity of the groove, and the surface of the slider is rotatably connected to the side of the roller.

[0014] The above technical solution improves the stability of the slider's sliding by using a groove.

[0015] The present invention is further configured such that limit grooves are provided at both ends of the inner cavity of the adjusting shell, and sliding blocks are welded to both ends of the threaded sleeve, with the surface of the sliding blocks slidably connected to the inner cavity of the limit grooves.

[0016] The above technical solution allows the sliding block to slide within its inner cavity via a limiting groove, thus improving the stability of the threaded sleeve sliding.

[0017] The present invention is further provided that support columns are welded around the bottom of the cable tray body, and anti-slip pads are adhered to the bottom of the support columns.

[0018] The above technical solution utilizes support columns to facilitate the support of the equipment.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. The hand crank, threaded rod, and threaded sleeve facilitate the adjustment of the distance between the protective shell and the winding equipment, thereby improving the accuracy and stability of winding. The motor and rotating rod facilitate the rotation of the wire roller to complete the winding work.

A controller 11 is bolted to the right side of the bearing plate 7. A hand crank 2 is movably connected to the surface of the adjusting shell 10. A threaded rod 14 is welded to the back of the hand crank 2. A threaded sleeve 13 is threadedly connected to the surface of the threaded rod 14. A protective shell 9 is bolted to the surface of the threaded sleeve 13. A motor 16 is bolted to the inner cavity of the protective shell 9. A rotating rod 15 is bolted to the left side of the motor 16. A wire roller 3 is bolted to the left side of the rotating rod 15, extending to the outside of the protective shell 9.

[0030] Furthermore, a sliding groove is provided on the other side of the bearing plate 7, and a sliding plate 4 is slidably connected to the surface of the sliding groove. The sliding groove improves the stability of the sliding plate 4.

[0031] Furthermore, the surface of the slide plate 4 is provided with a groove, and the inner cavity of the groove is slidably connected to the slider 5. The surface of the slider 5 is rotatably connected to the side of the roller 3. The groove improves the sliding stability of the slider 5.

[0032] Furthermore, limiting grooves are provided at both ends of the inner cavity of the adjusting shell 10, and sliding blocks 12 are welded to both ends of the threaded sleeve 13. The surface of the sliding block 12 is slidably connected to the inner cavity of the limiting groove. Through the limiting groove, the sliding block 12 can slide in its inner cavity, which improves the sliding stability of the threaded sleeve 13.

[0033] Furthermore, support columns are welded around the bottom of the cable tray body 1, and anti-slip pads are glued to the bottom of the support columns, which facilitates the support of the device.

[0034] Example 2:

[0035] refer to Figure 1 , 2 and Figure 4 The adjustable spacing current transformer winding cable arranger includes a housing 8 bolted to the inner side of a bearing plate 7, a cylinder 18 bolted to the center of the bottom of the housing 8, a push plate 17 bolted to the top of the cylinder 18, and a connecting block 19 bolted to the surface of the push plate 17. The surface of the connecting block 19 is bolted to the back of the adjusting housing 10. Through the cylinder 18, the push plate 17 and the connecting block 19, the height of the wire roller 3 can be easily adjusted, reducing the stretching length of the winding cable and improving the winding efficiency.

[0036] Furthermore, slide rails 20 are welded to both sides of the inner cavity of the housing 8, and both sides of the push plate 17 are slidably connected to the inner cavity of the slide rails 20. The slide rails 20 improve the sliding stability of the push plate 17.

[0037] The cable guide body 1, model (GP20) is a bare rod cable guide. During the cable laying process, the drive device drives the shaft or reel to perform a uniform cable laying operation. By reversing the operation, the cable is released from the reel.

[0038] Brief description of usage: First, when adjusting the distance between the wire roller 3 and the wire laying device 6, the user holds the hand crank 2 and rotates it clockwise. The hand crank 2 drives the threaded rod 14 to rotate. Since the threads on the surface of the threaded rod 14 and the threads in the inner cavity of the threaded sleeve 13 are threadedly connected, the rotation of the threaded rod 14 drives the threaded sleeve 13 to move, which in turn drives the protective shell 9 to move. The protective shell 9 then drives the wire roller 3 to move, effectively adjusting the distance between the wire roller 3 and the wire laying device 6. When adjusting the height of the sliding plate 4, the user starts the cylinder 18 via the controller 11. The cylinder 18 pushes the push plate 17 to move, which in turn drives the wire roller 3 to move. The moving connecting block 19 moves, which in turn drives the adjusting shell 10 to move. The adjusting shell 10 then drives the wire roller 3 to move upward, effectively adjusting the height of the wire roller 3. The user then places the cable to be wound onto the wire guide wheel on the surface of the wire guide device 6, and winds one end of the cable around and fixes it to the surface of the wire roller 3. The controller 11 then starts the motor 16 and the wire guide device 6, which moves left and right. At the same time, the wire guide wheel on the surface of the wire guide device 6 drives the cable to move left and right. Simultaneously, the motor 16 drives the rotating rod 15 to rotate, which in turn drives the wire roller 3 to rotate. The rotation of the wire roller 3 winds the cable.
