Description

Technical Field

[0001] The utility model relates to the technical field of cable or wire installation, in particular to a special wire release device for sheathed wires. Background Art

[0002] When the sheathed wire is manufactured and shipped out of the factory, it is usually wound on the wire drum in an orderly manner for the convenience of transportation, storage and subsequent use. When laying the sheathed wire, the wound sheathed wire needs to be paid out. Commonly used methods of paying out the wire include manual paying out and using auxiliary equipment to pay out the wire. Manual paying out requires the wire drum to be suspended and pulled and laid out along the predetermined line direction, which requires a lot of manpower and has low construction efficiency. Using a pay-out to pay out the wire can reduce the labor intensity of construction personnel, complete the pay-out task more quickly, save time, and improve construction efficiency.

[0003] The basic structure of the existing wire release device includes a base and a bracket. When in use, the bracket is passed through the wire drum and placed on the base, so that the wire drum remains suspended in the air, and then the sheath line is dragged to apply force to the wire drum so that the wire drum rotates on the wire release device to realize the wire release operation. This wire release device has certain requirements for the use site and needs to be used in a relatively flat site. In addition, this wire release device is relatively bulky, inconvenient to transport and has high maintenance costs.

[0004] A Chinese utility model patent with an authorization announcement number of CN221777250U and an authorization announcement date of 2024 / 09 / 27 discloses a portable and simple wire releaser. The portable and simple wire releaser of the patent includes a wire release mechanism, and the wire release mechanism includes an H-shaped wire release frame. When the H-shaped wire release frame is used, it is correspondingly inserted into the central through hole of the wire drum, and the other end of the H-shaped wire release frame extends out of one side of the wire drum and is installed with a rectangular frame at the bottom and the top. When using the wire releaser, the operator pulls the sheath wire, and the H-shaped wire release frame follows the pulling force to perform a circular motion with the central through hole of the wire drum as the center, thereby realizing the wire release operation. Compared with the existing wire releasers, the wire releaser has a simple structure, is convenient to carry and transport, saves time and effort, and improves the wire release efficiency. However, the wire releaser is inserted into the central through hole of the wire drum, and no fixing operation is performed between the wire releaser and the wire drum. During use, the wire releaser is easy to fall out of the central through hole of the wire drum. Utility Model Content

[0005] The utility model aims to provide a special wire release device for sheathed wires, so as to solve the problem that the existing wire release devices are easy to fall out during use.

[0006] In order to solve the above problems, the utility model of the special sheathed wire release device adopts the following technical solutions:

[0008] Further, the pay-off device base includes a central disc and connecting arms extending radially outward from the edge of the central disc, and the bobbin connection clip is arranged on the corresponding connecting arm.

[0009] Further, the bobbin connection clip includes a fixing plate, a clamping plate and a tightening bolt for tightening the fixing plate and the clamping plate. The fixing plate and the corresponding connecting arm are in guiding and movable cooperation along the radial direction of the central disc.

[0010] Further, a slider is arranged on one of the connecting arm and the fixing plate, and a sliding groove corresponding to the slider is arranged on the other one. The connecting arm and the fixing plate are in guiding and movable cooperation through the slider and the sliding groove.

[0011] Further, a tightening bolt is fixedly arranged on one of the fixing plate and the clamping plate, and a bolt hole cooperating with the tightening bolt is arranged on the other one. The tightening bolt passes through the bolt hole and is provided with a nut, and the nut configured on the tightening bolt is a wing nut.

[0012] Further, there are more than two connecting arms, and they are evenly arranged around the vertical rotating shaft.

[0013] Further, a centering seat for centering and cooperating with the central hole of the bobbin is arranged at the bottom of the pay-off device base.

[0014] Further, a bearing is arranged between the vertical rotating shaft and the pay-off device base.

[0015] Further, the sheathed wire guide is a guide sleeve, and both ends of the guide sleeve are flared mouths.

[0016] Further, a sheathed wire guide wheel is arranged at the top end of the vertical rotating shaft.

[0017] Advantageous effects: The special wire pay-off device for sheathed wires of the present utility model is a pioneering invention.

[0025] The features and performance of the present utility model will be further described in detail below in conjunction with embodiments.

[0026] The wire reel connecting clip used in the special wire pay - out device for sheathed wires of the present utility model utilizes the working principle of a clip for clamping objects, and can conveniently fix the pay - out device on the wire reel. Among them, the fixed plate and the clamping plate are equivalent to two mutually connected movable arms of the clip, and the used tightening bolt and nut are the locking devices of the clip; when the nut is tightened, the clamping plate approaches the fixed plate, and the pay - out device can be clamped and fixed to the wire reel, and when the nut is unscrewed, the clamping plate moves away from the fixed plate, and the pay - out device can be removed.

[0027] As a basic solution, the special wire pay - out device for sheathed wires of the present utility model includes a pay - out device base 1, as Figure 1 shown, a pay - out rack 3 is installed on the pay - out device base 1 to drive the sheathed wire reel 7 to rotate and pay out wires; as Figure 2As shown in the figure, the wire pay-off rack 3 includes a vertical rotating shaft 3-2 and a transverse arm 3-1. Among them, the vertical rotating shaft 3-2 is rotationally assembled on the pay-off device base 1, the transverse arm 3-1 is arranged on the vertical rotating shaft 3-2, and a sheathed wire guiding member is provided on the transverse arm 3-1. When paying off the wire, the head of the sheathed wire 8 is passed through the sheathed wire guiding member, and the transverse arm 3-1 is driven to rotate around the vertical rotating shaft 3-2 by pulling the sheathed wire 8. In order to facilitate the release of the sheathed wire 8, the distance between the sheathed wire guiding member and the vertical rotating shaft 3-2 is greater than the maximum outer diameter of the wire reel 7 adapted to the pay-off device. A wire reel connecting clip 2 is arranged at the edge of the pay-off device base 1 for fixedly clamping the edge of the wire retaining disc of the wire reel 7 adapted to the pay-off device.

[0028] As a preferred embodiment, the pay-off device base 1 includes a central disc and a connecting arm 1-2 extending radially outward from the edge of the central disc. The wire reel connecting clip 2 is arranged on the corresponding connecting arm 1-2. The pay-off device base 1 extends radially to form the connecting arm 1-2. The connecting arm 1-2 is provided to reduce the area of the original pay-off device base 1, reduce the weight of the pay-off device, make the pay-off device more portable, and also save the manufacturing cost of the pay-off device. In other embodiments, the connecting arm 1-2 and the pay-off device base 1 can adopt a split structure, and the connecting arm 1-2 is fixed on the pay-off device base 1 through a locking device.

[0029] As a preferred embodiment, the wire reel connecting clip 2 includes a fixing plate 2-3, a clamping plate 2-4, and a tensioning bolt 2-2 for tightening the fixing plate 2-3 and the clamping plate 2-4. The fixing plate 2-3 and the clamping plate 2-4 are connected by the tensioning bolt 2-2. Under the action of the tensioning bolt 2-2, a space is formed between the fixing plate 2-3 and the clamping plate 2-4 for placing the wire retaining disc of the wire reel. The fixing plate 2-3 and the corresponding connecting arm 1-2 are in guiding and movable cooperation along the radial direction of the central disc to adapt to more wire reels 7 of different models and specifications.

[0030] The wire reel connecting clip 2 is installed on the connecting arm 1-2 in a slidable manner. In order to achieve the purpose of slidably installing the wire reel connecting clip 2 on the connecting arm 1-2, as a preferred embodiment, as Figure 4 shown, a slider 2-5 is provided on one of the connecting arm 1-2 and the fixing plate 2-3, and a chute 1-3 corresponding to the slider 2-5 is provided on the other. The connecting arm 1-2 and the fixing plate 2-3 are in guiding and movable cooperation through the slider 2-5 and the chute 1-3, so that the wire reel connecting clip 2 can slide along the length direction of the connecting arm 1-2. In the specific implementation process, an opening also needs to be formed on the connecting arm for the slider 2-5 to enter the chute 1-3. In other alternative embodiments, the wire reel connecting clip 2 can also be directly slidably installed on the pay-off device base 1 to adapt to sheathed wire reels 7 of various sizes and specifications.

[0031] As a preferred embodiment, a tensioning bolt 2-2 is provided on one of the fixed plate 2-3 and the clamping plate 2-4, and a bolt hole matching with the tensioning bolt 2-2 is provided on the other, further simplifying the structure of the wire reel releasing device. One end of the tensioning bolt 2-2 is fixed on the fixed plate 2-3 or the clamping plate 2-4. During use, only the tensioning bolt 2-2 needs to be aligned with a bolt hole, which simplifies the working process of the bobbin connecting clip 2 and improves the working efficiency. The other end of the tensioning bolt 2-2 passes through the bolt hole and is configured with a nut. Further, a wing nut is used as the nut here. When disassembling and assembling the wire reel releasing device, it is necessary to adjust the tightening degree of the tensioning bolt 2-2 multiple times to make the clamping plate 2-4 approach or move away from the fixed plate 2-3. By using the wing nut 2-1, a wrench is no longer needed during the process of turning the nut, which simplifies the working process and improves the working efficiency.

[0032] As a preferred embodiment, there are two or more connecting arms 1-2, and they are evenly arranged around the vertical rotation axis 3-2, as Figure 5 shown. The wire reel releasing device fixed by the bobbin connecting clip 2 on one connecting arm 1-2 has low stability during use. Therefore, usually two or more connecting arms 1-2 are provided for combined use, and the multiple connecting arms 1-2 are evenly arranged to balance each fixing point, making the wire reel releasing device more stable and reliable during use.

[0033] As a preferred embodiment, a centering seat 1-1 for centering and mating with the central hole of the bobbin 7 is provided at the bottom of the wire reel releasing device base 1. As Figure 3 shown, the centering seat 1-1 at the lower part of the wire reel releasing device base 1 is arranged in a cylindrical shape adapted to the bobbin 7. During use, the centering seat 1-1 is snapped into the central hole of the bobbin 7, and the wire reel releasing device can be placed more accurately at the central position of the bobbin 7, facilitating the rotation of the wire reel rack 3. In other alternative embodiments, the centering seat 1-1 can also adopt other shapes, such as a cone or a cube whose circumscribed circle fits the central hole of the adapted bobbin, and the positioning function can also be achieved.

[0034] As a preferred embodiment, a bearing 4 is provided between the vertical rotation axis 3-2 and the wire reel releasing device base 1. The vertical rotation axis 3-2 is installed at the center of the wire reel releasing device base 1 through the bearing 4. The balls in the bearing 4 make the circumferential rotation of the vertical rotation axis 3-2 around the center of the wire reel releasing device base 1 smoother. In other alternative embodiments, the friction during the rotation of the vertical rotation axis 3-2 can also be reduced by adding lubricating oil or using fine sandpaper to polish the surface of the assembled part of the vertical rotation axis.

[0035] As a preferred embodiment, the sheathed wire guide is a guide sleeve 3-3. Compared with other devices or components that can limit the displacement of the sheathed wire, the guide sleeve 3-3 fits the shape of the sheathed wire better and can better pull and limit the sheathed wire when in use. Both ends of the guide sleeve 3-3 are bell mouths, and the use of bell mouths can reduce the damage of the guide sleeve 3-3 ports to the insulation of the sheathed wire. In other embodiments, the two ends of the guide sleeve 3-3 can also be curled, which can also protect the insulation of the sheathed wire.

[0036] As a preferred embodiment, a sheath wire guide wheel 5 is provided at the top of the vertical rotating shaft 3-2, and the pulley 5-1 is installed at the top of the vertical rotating shaft 3-2 through the fixed shaft 5-2 and the pulley 5-1 seat. Figure 6 When in use, a sheath wire guide wheel 6 can be set above the wire unwinder. The sheath wire guide wheel can reduce the resistance during the wire unwinding process, making the wire unwinding process more labor-saving, and the rolling friction can more easily protect the cable.

[0037] The implementation process of this embodiment is as follows: when performing the wire release operation, the wire release device needs to be fixed on the bobbin 7 first, the butterfly nut 2-1 is unscrewed, the clamping plate 2-4 is removed, and the centering seat 1-1 is placed in the center hole of the bobbin 7, and the fixing plate 2-3 is slid and adjusted to an appropriate position through the slide groove 1-3 to clamp the bobbin retaining plate, and then the tensioning bolt 2-2 is aligned with the bolt hole to install the clamping plate 2-4, and then the butterfly nut 2-1 is tightened, so that the wire release device is firmly fixed on the bobbin 7. After the wire release device is fixed, the wire end of the sheathed wire that needs to be released is passed through the bell-mouth guide sleeve 3-3 on the horizontal arm 3-1, and then passed through the sheathed wire guide wheel 5 set at the top of the vertical rotating shaft 3-2 and the sheathed wire guide wheel 6 placed above the wire release device in turn, and the wire end is dragged to the required location to complete the wire release operation. When the wire-releasing operation is completed and the wire-releasing device is removed from the wire drum 7, the butterfly nut 2-1 is unscrewed and the clamping plate 2-4 is removed to remove the wire-releasing device.
