[0002] In wind power engineering, cable erection is one of the key steps. Using a wire pay - out device can efficiently lay cables evenly to the designated position. It can ensure the balance of cable tension, prevent damage, and improve construction accuracy and speed. During the interruption period or after the use of the wire pay - out reel, the cable is generally locked to prevent the cable from becoming loose.

[0003] When the existing wire pay - out device locks the cable, it usually directly clamps the cable with a simple device. This method has a poor locking effect on the cable and low stability. Under the action of external forces, the cable is easily loosened, and the cable specifications vary. Generally, the clamping effect of the clamping device on cables of different specifications cannot be consistent. Therefore, a wire pay - out device that can clamp different cables with high stability is needed. Content of the Utility Model

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can also be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0028] Embodiment 1:

[0029] This embodiment provides a wire-releasing device for facilitating the locking of cables in wind power operation construction, specifically as Figures 1 - 2 shown, including a wire-releasing frame 101, on which a wire-releasing disc is installed. The wire-releasing disc includes a wire-releasing shaft 103 and wire-releasing side plates 104 respectively installed at both ends thereof, and further includes a locking component 2 for locking the cable.

[0030] As Figures 3 - 6As shown, the locking component 2 includes a guide frame 201, which is mounted on the pay-off frame 101, and a slide plate 208 is mounted on the guide frame 201. Two sets of tightening units are mounted on the slide plate 208 in a mirror-image arrangement and close to each other. The tightening unit includes a guide shaft 210 and a locking screw 206. The locking screw 206 is threadedly connected to the guide shaft 210. The locking screw 206 is provided with two stepped surfaces. The guide shaft 210 is rotatably connected to the slide plate 208. The guide shaft 210 is provided with a circumferential wall surface. A first wire-releasing groove 211 and a second wire-releasing groove 212 are provided, and the guide shaft 210 is radially provided with a plurality of first locking holes 213 and second locking holes 214 at the same height as the first wire-releasing groove 211 and the second wire-releasing groove 212, a first locking ball 215 is placed in each first locking hole 213, and a second locking ball 216 is placed in each second locking hole 214; the two step surfaces of the locking screw 206 are respectively matched with the first locking ball 215 and the second locking ball 216.

[0031] The staff chooses to pass the cable through the circular gap between the two first cable-releasing grooves 211 or the second cable-releasing grooves 212 according to the actual diameter of the cable, and uses the two tensioning units to limit the cable; when it is no longer necessary to release the cable, the staff turns the locking screw 206 to make the locking screw 206 go deeper into the guide shaft 210. At this time, the two stepped surfaces of the guide shaft 210 will press down the first locking ball 215 and the second locking ball 216 respectively. After being squeezed, the first locking ball 215 and the second locking ball 216 will be tightened along the first locking hole 213 and the second locking hole 214. The second locking holes 214 spread outward until they move to the ends of the first locking hole 213 and the second locking hole 214. The ends of the first locking hole 213 and the second locking hole 214 are provided with a tie mouth. At this time, the first locking ball 215 and the second locking ball 216 will squeeze the cables between the two first wire-releasing grooves 211 or the second wire-releasing grooves 212, thereby locking the cables. Due to the self-locking property of the thread between the locking screw 206 and the guide shaft 210, the locking effect of the first locking ball 215 and the second locking ball 216 on the cables will not be relaxed.

[0032] When it is necessary to release the line, the locking screw 206 is screwed up, but it is not necessary to screw it out completely. It is screwed until the first locking ball 215 and the second locking ball 216 can be retracted to the first locking hole 213 and the second locking hole 214 close to the center of the guide shaft 210, and the two stepped surfaces of the locking screw 206 can limit the first locking ball 215 and the second locking ball 216. Figure 7 As shown, at this time, the first locking ball 215 and the second locking ball 216 are blocked by the stepped surface of the locking screw 206 , and thus will not escape from the first locking hole 213 and the second locking hole 214 .

[0033] If the cable diameter is slightly smaller than the diameter of the circle formed by the first wire-releasing groove 211 or the second wire-releasing groove 212, then the screwing position of the locking screw 206 is controlled so that the locking screw 206 slightly squeezes out the first locking ball 215 and the second locking ball 216 to support the cable so that the cable will not lose support.

[0034] If the first locking ball 215 and the second locking ball 216 need to be removed, the locking screw 206 should be completely unscrewed. At this time, 315 and 316 lose the limit of the locking screw 206 and can be separated from the first locking hole 213 and the second locking hole 214, so as to be taken out and replaced.

[0035] Through the above arrangement, the locking component 2 can guide and transmit cables of different specifications, and can also lock these cables, and its locking stability is high and not easy to loosen.

[0036] Embodiment 2:

[0037] This embodiment further expands the locking component 2 on the basis of the embodiment 1. Figure 4 As shown, a gear 209 is installed on the guide shaft 210 , and two gears 209 are meshed. An auxiliary motor 203 is installed on the guide frame 201 , and the auxiliary motor 203 is transmission-connected to a gear 209 .

[0038] When the auxiliary motor 203 is started, the two gears 209 will start to rotate, and at this time the two guide shafts 210 will start to rotate in different directions. By controlling the rotation direction of the auxiliary motor 203, auxiliary retraction and release of the cable can be achieved, reducing the rotation load at the reel.

[0039] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0040] Embodiment 3:

[0041] This embodiment further expands the locking component 2 on the basis of the embodiment 2. Figure 3 As shown, the slide plate 208 and the auxiliary motor 203 are slidably connected to the guide frame 201 .

[0042] When winding the cable, the sliding plate 208 is used to make the cable evenly and regularly wound on the pay-off drum; when paying out the cable, the sliding plate 208 automatically slides following the position of the cable to ensure that the cable slides stably into the locking component 2.

[0043] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0044] Embodiment 4:

[0045] This embodiment further expands the locking component 2 on the basis of Embodiment 3, specifically as follows Figure 4 As shown, a locking plate 202 is slidably connected to the guide frame 201. A first spring 205 is provided between the locking plate 202 and the guide frame 201. A gasket 207 is sleeved on the locking screw 206. The locking plate 202 is located between the gasket 207 and the guide shaft 210.

[0046] When locking the cable, the locking screw 206 is tightened. At this time, the gasket 207 presses down the locking plate 202 against the elastic force of the first spring 205. When the cable is locked, the locking plate 202 also presses on the guide shaft 210. At this time, due to the downward pressure of the locking plate 202 on the guide shaft 210, the sliding plate 208 will not easily slide, further improving the stability of cable locking.

[0047] Other parts of this embodiment are the same as those of the above embodiments and will not be described in detail.

[0048] Embodiment 5:

[0049] This embodiment further expands the locking component 2 on the basis of Embodiment 4, specifically as follows Figure 3 、 Figure 8 As shown, a latch 217 is slidably connected to the guide frame 201. A second spring 204 is provided between the latch 217 and the guide frame 201. One end of the latch 217 is provided with a wedge surface. The locking plate 202 cooperates with the wedge surface. A plurality of limiting holes 105 are provided on the wire-releasing side plate 104. The latch 217 cooperates with the limiting holes 105.

[0050] When the locking plate 202 is pressed down, the locking plate 202 will squeeze the wedge surface of the latch 217. At this time, the latch 217 extends out of the guide frame 201 against the elastic force of the second spring 204 and then engages into the limiting hole 105, making the wire-releasing side plate 104 unable to rotate either, further improving the stability when the cable is locked.

[0051] Other parts of this embodiment are the same as those of the above embodiments and will not be described in detail.

[0052] Embodiment 6:

[0053] This embodiment further expands on the basis of Embodiment 1, specifically as follows Figure 1 As shown, a lifting hole 106 is provided on the wire-releasing side plate 104. By providing the lifting hole 106, it is convenient to lift this device during high-altitude operations.

[0054] Other parts of this embodiment are the same as those of the above embodiments and will not be described in detail.

[0055] Embodiment 7:

[0056] This embodiment further expands on the basis of Embodiment 1, specifically as follows Figure 1As shown, a plurality of universal wheels 102 are provided on the wire pay-off rack 101. By providing the universal wheels 102, it is convenient for the staff to move the device over a short distance.

[0057] Other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0058] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Any simple modification or equivalent change made to the above embodiments based on the technical essence of the present invention falls within the protection scope of the present invention.
