Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, and in particular to a fast cable reel laying fixture structure. Background Technology

[0002] In many critical fields such as power construction and communication infrastructure development, cables, as the core carrier of electrical energy and signal transmission, are widely used. From laying urban power grids to building communication base stations in remote areas, from power supply to large industrial plants to internal wiring in civil buildings, cables play an indispensable role. To facilitate cable storage and transportation, cables are usually wound on cable reels. This storage method not only effectively protects the cables from damage during transportation but also makes it easy to measure cable length, facilitating management and use during construction. However, in actual construction layout, traditional cable laying methods have many inconveniences, seriously affecting construction efficiency. A common traditional laying method is using a cable laying frame. In this method, the cable reel is threaded onto the rotating shaft of the cable laying frame, and then the cable on the reel is manually pulled to rotate the reel around the shaft, thus laying the cable. However, this method has significant drawbacks. The cable laying frame has a relatively complex structure, occupies a large space, and is inconvenient to move and adjust on the construction site. Furthermore, cable laying frames are relatively expensive, and for some small construction projects or temporary construction sites, purchasing and maintaining them increases construction costs. Another traditional method is to directly pull the cable around the cable reel to unload it. This method seems simple, but it has many problems in practice. It's cumbersome, requiring workers to constantly walk around the cable reel to ensure smooth cable unloading, which not only increases the labor intensity of the workers but also reduces laying efficiency. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model aims to provide a simple and low-cost cable reel quick-laying fixture structure to improve laying efficiency and reduce labor intensity.

[0004] To achieve the above objectives, this utility model proposes a rapid cable reel unloading fixture structure, including a cable reel and an unloading fixture. The cable reel includes a shaft and a cable wound on the shaft. A shaft hole is pre-drilled at the center of the side of the shaft. The unloading fixture includes a sleeve base and an unloading bracket. The cable reel is placed flat on the ground. The sleeve base is inserted into the shaft hole of the shaft and is equipped with a counterweight at its bottom end. The unloading bracket includes a vertical bracket and a horizontal bracket fixed in the middle of the vertical bracket. The lower end of the vertical bracket is movably inserted into the sleeve base. The horizontal bracket is positioned higher than the top surface of the shaft and its length is greater than the radius of the shaft. Guide rings are installed at the top of the vertical bracket and the end of the horizontal bracket. The lead-out end of the cable passes through the guide rings on the horizontal bracket and the vertical bracket in sequence. During unloading, pulling the lead-out end upward will cause the unloading bracket to rotate around the sleeve base, thereby guiding the cable and achieving smooth unloading of the cable.

[0005] In the above solution: the sleeve base, the wire feeding bracket, and the guide ring are all metal parts; the horizontal bracket is welded to the vertical bracket; and the guide ring is welded to the corresponding horizontal or vertical bracket. The components of the wire feeding fixture can be made of common metal materials, resulting in low raw material costs.

[0006] In the above scheme: the counterweight is a cylindrical concrete block, which is cast and connected to the bottom end of the sleeve base. Its outer diameter is larger than that of the sleeve base and matches the diameter of the shaft hole. This design allows the sleeve base to be more stably placed in the shaft hole of the shaft disc after being inserted into the shaft hole, and it will not easily come out due to the tension during the wire release process.

[0007] In the above scheme: the top of the sleeve base extends beyond the shaft hole to avoid interference between the wire feeding bracket and the shaft plate.

[0008] In the above scheme, the guide rings on both the horizontal and vertical supports are horizontally arranged. The cable leads pass through the guide rings on the horizontal and vertical supports from bottom to top, avoiding additional friction caused by excessive local stress on the cable due to the angle of the guide rings. For example, if the guide rings are tilted, the cable may experience friction at a large angle with the edge of the guide ring when passing through, increasing the resistance to cable laying. Horizontally arranged guide rings can effectively reduce this situation, allowing the cable to pass through the guide rings more easily and achieving smooth cable laying.

[0009] In the above scheme, the length of the horizontal support is half the length of the vertical support. This ratio allows operators to more accurately control the cable's direction during the laying process. The relatively long length of the vertical support, as the main support and guiding structure, ensures stable guidance of the cable in the vertical direction. The appropriate length of the horizontal support allows for reasonable control of the cable's horizontal movement, preventing excessive horizontal swaying of the cable due to an excessively long horizontal support, thereby improving the accuracy of the laying process.

[0010] The above solution also includes a counterweight disc. The upper outer circle of the sleeve base is provided with an external thread, and the center of the counterweight disc is provided with a threaded hole that matches the external thread. The counterweight disc is threaded onto the sleeve base through the threaded hole and supported on the top surface of the shaft disc. This structure further restricts the swaying and rotation of the sleeve base by adding a counterweight disc.

[0011] In the above scheme, the counterweight disc is an iron disc to ensure that the counterweight disc has a small volume and a large mass.

[0012] The beneficial effects of this utility model are as follows: 1. It greatly simplifies the operation process. During use, simply insert the sleeve base into the shaft hole of the shaft disc, and then insert the cable feeding bracket into the sleeve base. When feeding the cable, simply pull the cable lead-out end upwards to rotate the cable feeding bracket around the sleeve base, thus guiding and feeding the cable. The entire process requires no complex installation or debugging, and no frequent relocation of personnel, greatly improving the convenience of operation and saving time and labor costs. 2. The cable feeding fixture has a simple structure, mainly composed of a sleeve base, a cable feeding bracket, and a guide ring. It has low processing costs and a compact size, making it easy to transport and store. 3. The horizontal support is positioned higher than the top surface of the shaft disc, and its length is greater than the radius of the shaft disc. This design effectively prevents the cable from contacting the shaft disc during the feeding process, thus avoiding frictional resistance. Attached Figure Description

[0015] Figure 3 Is Figure 2 A schematic diagram of the structure with an added counterweight disc. Detailed Implementation

[0016] like Figure 1 As shown in Figure 2, a cable reel quick-release fixture structure mainly consists of a cable reel and a release fixture. The cable reel includes a shaft reel 1 and a cable 2 wound on the shaft reel 1, with a shaft hole pre-drilled at the center of the side of the shaft reel 1.

[0017] The cable laying fixture includes a sleeve base 3 and a cable laying bracket 4. The cable reel is laid flat on the ground. The sleeve base 3 is inserted into the shaft hole of the shaft plate 1, and its bottom end is equipped with a counterweight 31. The cable laying bracket 4 includes a vertical bracket 41 and a horizontal bracket 42 fixed in the middle of the vertical bracket 41. The lower end of the vertical bracket 41 is movably inserted into the sleeve base 3. The horizontal bracket 42 is arranged at a height higher than the top surface of the shaft plate 1, and its length is greater than the radius of the shaft plate 1.

[0018] Guide rings 5 ​​are installed at the top of the vertical support 41 and the end of the horizontal support 42. The lead-out end of the cable 2 passes through the guide rings on the horizontal support 42 and the vertical support 41 in sequence. When laying the cable, pulling the lead-out end upward will cause the cable laying support 4 to rotate around the sleeve base 3, thereby guiding the cable 2 and enabling the cable 2 to be laid smoothly.

[0019] Ideally, the sleeve base 3, the wire feeding bracket 4, and the guide ring 5 should all be metal parts, with the horizontal bracket 42 welded to the vertical bracket 41, and the guide ring 5 welded to the corresponding horizontal bracket 42 or vertical bracket 41. The components of the wire feeding fixture can be made of common metal materials, resulting in lower raw material costs.

[0020] Ideally, the counterweight 31 is a cylindrical concrete block, cast and connected to the bottom of the sleeve base 3. Its outer diameter is larger than that of the sleeve base 3 and matches the diameter of the shaft hole. This design allows the sleeve base 3 to sit more stably in the shaft hole of the shaft disc 1 after being inserted into the shaft hole, and it will not easily come out due to the tension during the wire release process.

[0021] Ideally, the top of the sleeve base 3 should extend beyond the shaft hole to avoid interference between the wire feeding bracket 4 and the shaft disk 1.

[0022] Ideally, the guide rings 5 ​​on both the horizontal support 42 and the vertical support 41 should be horizontally arranged, with the cable 2's lead-out end passing through the guide rings on both the horizontal support 42 and the vertical support 41 from bottom to top. This avoids additional friction caused by excessive localized stress on the cable 2 due to the angle of the guide rings 5. For example, if the guide rings 5 ​​are tilted, the cable 2 may experience significant friction with the edge of the guide rings 5 ​​when passing through, increasing the resistance to cable laying. Horizontally arranged guide rings 5 ​​effectively reduce this situation, allowing the cable 2 to pass through the guide rings 5 ​​more easily and achieve smooth cable laying.

[0023] Ideally, the length of the horizontal support 42 should be half the length of the vertical support 41. This proportion allows operators to more precisely control the direction of the cable 2 during the laying process. The relatively long length of the vertical support 41, as the main support and guide structure, ensures stable guidance of the cable 2 in the vertical direction. The moderate length of the horizontal support 42 allows for reasonable control of the cable 2's horizontal movement, preventing excessive horizontal swaying of the cable 2 due to an excessively long horizontal support 42, thereby improving the accuracy of the laying process.

[0024] Ideally, it also includes a counterweight disc 6. The upper outer circle of the sleeve base 3 is provided with an external thread, and the center of the counterweight disc 6 is provided with a threaded hole that matches the external thread. The counterweight disc 6 is threaded onto the sleeve base 3 through the threaded hole and supported on the top surface of the shaft disc 1. This structure further restricts the swaying and rotation of the sleeve base 3 by adding a counterweight disc 6.

[0025] Ideally, the counterweight disc 6 should be made of iron to ensure that it is small in size but heavy in mass. Specifically, the counterweight disc 6 can weigh 10-20 kg.
