Description

Technical Field

[0001] This invention relates to the field of wire laying technology, and more specifically to a device for taking in and laying out sheet-shaped grounding wires. Background Technology

[0002] Copper foil or copper strip grounding wires have a large surface area and low resistance, making them widely applicable. Laying copper foil grounding wires in power distribution room is a key measure to prevent electrostatic interference and ensure the safe and stable operation of equipment. It can quickly and safely conduct static charges generated by equipment and personnel activities to the ground, ensuring that conductive objects in the room are at the same or close potential and eliminating potential differences. This is an important component of the equipotential grounding system for power distribution room, especially for precision electronic equipment and control systems.

[0003] In existing power distribution network equipment rooms, when laying copper foil grounding wires, the installers push the grounding wire reel forward to lay multiple grounding wires horizontally and vertically within the equipment room. During the laying process, the installers need to bend over to control the rolling path of the reel at lower heights, which is labor-intensive. Furthermore, the narrow and wide reel is at risk of tilting or tipping over during the rolling process. When laying multiple paths, the installers need to frequently bend over to cut the grounding wires, making the operation quite inconvenient. Therefore, we propose a sheet-like grounding wire take-up and lay-up device. Summary of the Invention

[0004] The purpose of this invention is to provide a device for taking in and releasing sheet-like grounding wires to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a device for taking in and releasing a sheet-like grounding wire, comprising:

[0006] Two wire feeding frames are arranged side by side, a fixing block is provided between the two wire feeding frames, and the lower surface of the wire feeding frames is provided with moving wheels;

[0007] A rotating shaft is located inside a receiving groove opened inside the wire feeding frame, and bearings are rotatably mounted at both ends of the rotating shaft, with a limit protrusion fixed in the middle of the outer surface of the bearing.

[0008] A first guide groove is formed on the inner sidewall of the receiving groove to cooperate with the limiting protrusion;

[0009] A support assembly is provided on the rotating shaft so that the rotating shaft and the grounding wire disc are connected to form a whole;

[0010] A cutting component is provided at one end of the wire feeding frame to cut the grounding wire during wire feeding;

[0011] The push rod is rotatably mounted on one side wall of the wire feeding frame to move the wire feeding frame and to drive the cutting component to move when cutting the wire.

[0012] Preferably, the support assembly includes a support block and an adjusting screw rod. The adjusting screw rod is rotatably installed inside the rotating shaft. Both ends of the outer surface of the adjusting screw rod are connected with threaded barrels through threaded parts. A support rod is rotatably connected to the threaded barrel. A second guiding groove for cooperating with the support rod is opened inside the rotating shaft. The support block is rotatably installed at one end of the support rod to support the inner barrel of the grounding wire.

[0013] Preferably, a clamping piece is fixed on one side wall of the support block.

[0014] Preferably, at least two support blocks are arranged circumferentially along the rotating shaft. A second rotating handle is fixed at one end of the adjusting screw rod.

[0015] Preferably, a first rotating handle is fixed on the outer surface of one end of the rotating shaft.

[0016] Preferably, the cutting assembly includes a cutting tool body and a moving plate. The moving plate is fixed on one end face of the wire pay-off frame. A groove is opened on the side wall of the moving plate. The cutting guide block is detachably connected to the side wall of the wire pay-off frame. A convex block for cooperating with the groove is arranged on one side wall of the cutting guide block. A return spring for cooperating with the convex block is arranged inside the groove. The cutting tool body is fixed at the lower end of the moving plate.

[0017] Preferably, the cutting tool body and the moving plate are fixed by welding or bolts.

[0018] Preferably, a damping sliding groove is penetrated and opened inside the fixed block. A guide plate is slidably connected inside the damping sliding groove.

[0019] [[ID=CH=22]]Preferably, a damping rubber for abutting against the guide plate is arranged on one side of the inner surface of the damping sliding groove.

[0020] Preferably, the push rod is in a "冂" shape.

[0021] [[ID=2CH=28]]Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] (1) Through the wire pay-off frame, moving wheels, rotating shaft, support assembly, bearings, first guiding groove and limiting convex blocks, the present invention avoids the need for manual bending to roll the grounding wire reel for wire pay-off, and the disk body with a relatively narrow width is skewed and toppled. When the device is paying off wire, it is not necessary to bend down, and the wire pay-off frame can be pushed to move, so that the grounding wire reel rolls on the ground for wire pay-off. When paying off wire, the vertical state of the disk body can be well guaranteed, reducing the distortion of the grounding wire path caused by skewing, and well avoiding the skewing and toppling of the disk body during rolling. The device can be used for paying off grounding wires of different specifications and sizes, improving the application range of the device.

[0023] (2) By setting up a rotating shaft, support components, fixing blocks, a first handle and a guide plate, the need to manually wind up the grounding wire is avoided when too much length of grounding wire is accidentally released. This device can quickly wind up grounding wires of different lengths by rotating the rotating shaft, improving winding efficiency. Moreover, it can guide the movement direction of the wire segment during winding, ensuring that the edge of the grounding wire disc is flush after being wound into a disc, thus increasing the practicality of the device.

[0024] (3) By setting up a cutting guide block, a cutting blade, a moving plate and a reset spring, it is not necessary to bend over manually after laying the wire to a suitable length and then manually cut the wire. This device does not require bending over. By pressing the push rod, the cutting blade can be moved to cut the grounding wire. The operation is simple, reducing the intensity of manual labor and improving the convenience of wiring. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1-10 This invention provides a technical solution: a device for taking in and releasing a sheet-like grounding wire, comprising:

[0038] Two wire feeding frames 1 are arranged side by side, a fixing block 9 is provided between the two wire feeding frames 1, and a moving wheel 3 is provided on the lower surface of the wire feeding frame 1;

[0039] The rotating shaft 4 is located inside the receiving groove 2 opened inside the wire feeding frame 1, and bearings 7 are rotatably installed at both ends of the rotating shaft 4, and a limiting protrusion 11 is fixed in the middle of the outer surface of the bearing 7.

[0040] The first guide groove 10 is formed on the inner side wall of the receiving groove 2 to cooperate with the limiting protrusion 11;

[0041] like Figure 1-3 As shown, the first guide groove 10, in conjunction with the limiting protrusion 11, effectively prevents the rotating shaft 4 from tilting vertically, keeping it horizontal. This ensures that the grounding wire reel, which mates with the rotating shaft 4, remains vertical during the wire laying process, preventing it from tilting. Additionally, as... Figure 10 As shown, the device has a large height of the receiving trough 2, which can accommodate grounding wire reels of different outer diameters to roll well on the ground, and the two wire feeding frames 1 are spaced far apart, which can accommodate grounding wire reels of different widths, thus improving the applicability of the device.

[0042] Support component 8 is mounted on the rotating shaft 4 so that the rotating shaft 4 and the grounding wire disc are connected to form a whole;

[0043] By having the support component 8 press against the inner cylinder inside the grounding wire reel, the rotating shaft 4 rolls along with the grounding wire reel as it rolls along the ground, reducing the relative sliding friction between the rotating shaft 4 and the grounding wire reel. During the wire laying process, the rotating shaft 4 ensures that the grounding wire reel is in a vertical position, reducing skewness. In addition, it also facilitates the rotation of the support component 8 by the rotating shaft 4 later, thereby winding up the laid-out grounding wire segment.

[0044] Cutting component 6 is set at one end of wire feeding frame 1 to cut the grounding wire during wire feeding;

[0045] To avoid having to bend over manually to cut the wire segments when laying the grounding wire onto the reel;

[0046] Push rod 5 is rotatably mounted on one side wall of wire feeder 1 to push wire feeder 1 to move, and to drive cutting assembly 6 to operate when cutting wire.

[0047] It facilitates the movement of the movable frame 1 and can drive the cutting component 6 of this device to move, avoiding the need for additional parts to drive the cutting component 6 and reducing manufacturing costs.

[0048] Preferably, the support assembly 8 includes a support block 82 and an adjusting screw 83. The adjusting screw 83 is rotatably mounted on the inner side of the rotating shaft 4, and the two ends of the outer surface of the adjusting screw 83 are connected to the threaded cylinder 84 through the threaded part. The threaded cylinder 84 is rotatably connected to the support rod 81, and the inner side of the rotating shaft 4 is provided with a second guide groove 401 that cooperates with the support rod 81. The support block 82 is rotatably mounted on one end of the support rod 81 to support the inner cylinder of the grounding wire.

[0049] like Figure 5 As shown, the threaded portion on the outer surface of the adjusting screw 83 has threads in opposite directions, which facilitates driving the threaded cylinders 84 at both ends of the adjusting screw 83 to move in opposite directions, thereby causing the support block 82 to rise or fall. When the support block 82 rises, it cooperates with the inner cylinder of the grounding wire reel, so that the rotating shaft 4 and the grounding wire reel are connected to form a whole, thereby causing the rotating shaft 4 to rotate with the grounding wire reel. The first guide groove 10 at the end of the rotating shaft 4 cooperates with the limiting protrusion 11 to restrict the grounding wire reel to move only vertically up and down, preventing it from tilting and ensuring the straightness of the wire path during wire laying. As the grounding wire reel gradually lays the wire, causing the outer diameter of the reel to decrease, the grounding wire reel can make good contact with the ground under the action of gravity and roll on the ground. After the wire laying is completed, the support block 82 can be lowered to release the contact with the inner cylinder of the grounding wire reel, so as to replace another reel of grounding wire.

[0050] Preferably, a clamping piece 86 is fixed to one side wall of the support block 82;

[0051] like Figure 9 As shown, when winding up the released grounding wire segment, one end of the segment can be temporarily clamped to facilitate the winding action.

[0052] Preferably, the support block 82 is provided at least twice along the circumference of the rotating shaft, and a second handle 85 is fixed to one end of the adjusting screw 83;

[0053] Multiple support blocks 82 can be set along the rotating shaft 4, so that the grounding wire reel after winding can form a better circle when winding the grounding wire. During the winding process, by adjusting the distance between the support blocks 82 and the rotating shaft 4, it is convenient to adjust the height of the rotating shaft 4 during winding, and also convenient to adjust the outer diameter of the grounding wire reel after winding. The second handle 85 facilitates quick operation to adjust the rotation of the lead screw 83.

[0054] Preferably, a first handle 12 is fixed to the outer surface of one end of the rotating shaft 4;

[0055] like Figure 4 As shown, this allows for rapid rotation of the shaft 4 by manual rotation when winding up the released grounding wire segment.

[0056] Preferably, the cutting assembly 6 includes a cutting blade 62 and a moving plate 63. The moving plate 63 is fixed to one end face of the wire feeding frame 1. A groove is provided on the side wall of the moving plate 63. The cutting guide block 61 is detachably connected to the side wall of the wire feeding frame 1. A protrusion that cooperates with the groove is provided on one side wall of the cutting guide block 61. A return spring 64 that cooperates with the protrusion is provided inside the groove. The cutting blade 62 is fixed to the lower end of the moving plate 63.

[0057] like Figure 7 As shown, during the wire laying process, the push rod 5 is rotated downwards to drive the moving plate 63 to move downwards. The moving plate 63 then drives the cutting blade 62 to move downwards to cut the grounding wire from the grounding wire reel. After cutting, the reset spring 64 drives the moving plate 63 to move upwards for reset, facilitating the next operation. More preferably, a pad can be arranged below the cutting blade 62. The pad is connected to the wire laying frame 1 via a chain. In this way, when laying wires outdoors, the grounding wire can be cut by the cooperation of the pad and the cutting blade 62, avoiding the impact of soft ground soil on the cutting effect.

[0058] Preferably, the cutting blade 62 and the movable plate 63 are fixed by welding or bolts.

[0059] Preferably, a damping groove 13 is provided through the inner side of the fixing block 9, and a guide plate 15 is slidably connected to the inner side of the damping groove 13;

[0060] like Figure 9 As shown, this facilitates the adjustment of the guide plate 15, so that the spacing between the two guide plates 15 can be adapted to the sheet grounding wires of different widths. The guide plate 15 ensures that the edges of both ends of the reel are flush after winding, thus improving the winding effect.

[0061] Preferably, a damping rubber 14 that abuts against the guide plate 15 is provided on one side of the inner surface of the damping groove 13;

[0062] It is convenient to utilize the elastic force of the damping rubber 14 to clamp and lock the guide plate 15 after adjusting the position of the guide plate 15. Further preferably, the damping rubber 14 can also be replaced with an elastic clip.

[0063] Preferably, the push rod 5 is in a "冂" shape.

[0064] It is convenient to better drive the two wire pay-off stands 1 to move by manually pushing the push rod 5.

[0065] The working principle and usage process of the present invention: When paying off the wire, as Figure 1 shown, sleeve the copper foil grounding wire reel on the outer side of the rotating shaft 4, rotate the adjusting screw rod 83, make the threaded cylinders 84 at both ends of the adjusting screw rod 83 approach each other, and then drive the support rod 81 to jack up to the side away from the rotating shaft 4, make the support block 82 contact the inner cylinder of the grounding wire reel, then place the rotating shaft 4 between the two wire pay-off stands 1, and through the cooperation of the limiting convex block 11 and the first guiding groove 10, ensure that the grounding wire reel maintains a vertical state without tilting. At this time, the wire pay-off stand 1 can be driven to move through the push rod 5, and the grounding wire reel rolls on the ground to pay off the wire. After paying off an appropriate length of wire, press the push rod 5 to make the push rod 5 contact the moving plate 63 and make it move downward. The return spring 64 is elastically compressed and shortened. The moving plate 63 drives the cutting tool body 62 to move downward, and the grounding wire is cut through the cooperation of the ground and the cutting tool body 62, and the wire pay-off can be completed. After cutting, the return spring 64 drives the moving plate 63 and the cutting tool body 62 to move upward for resetting;

[0066] When taking up the wire, as Figure 9 shown, one end of the sheet-shaped grounding wire can be inserted between the clamping piece 86 and the support block 82, and the end of the grounding wire is temporarily fixed by the elastic clamping of the clamping piece 86. Make the guide plate 15 slide inside the damping chute 13 to adjust the guide plate 15 to align with the two side edges of the grounding wire. Then manually rotate the rotating shaft 4 through the first rotating handle 12, and the rotating shaft 4 drives the grounding wire to rotate for taking up. During the taking-up process, it is guided by the guide plate 15 to improve the flatness effect of the edge of the grounding wire reel after taking up.

[0067] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
