[0001] The present application relates to the technical field of cable pay-off racks, and in particular to a cable laying and cable retracting and releasing structure. Background Art

[0002] The cables in power engineering are usually wound on an I-shaped reel. When laying the cables, the reel is set on a pay-off rack. The pay-off rack is a structure used for cable reeling and winding. It is mainly composed of a bracket and a rotating shaft. When in use, the rotating shaft is removed and inserted into the center of the cable reel. The rotating shaft is set up by the bracket to make the reel roll and pay out the cable. Some rotating shafts are also connected to motors to assist in reeling and winding.

[0003] In actual construction, the cables used have various specifications, and the specifications of the reels used are also different. When the cable retraction and release structure does not match the reel specifications, it is inconvenient to retract the cables after the reel is erected. Summary of the invention

[0032] The present application is further described in detail below in conjunction with the accompanying drawings.

[0033] See also Figure 1 and Figure 2 , is a cable laying and cable retracting structure disclosed in an embodiment of the present application, including a support frame 1, two support frames 1 are arranged in mirror symmetry, and moving wheels 2 are arranged under the support frames 1, and a lifting frame 3 is slidably installed on the support frame 1, and the lifting frame 3 is connected to a lifting drive 31, and a central shaft 4 is rotatably installed on the lifting frame 3, and both ends of the central shaft 4 are rotatably installed on the lifting frames 3 on both sides, respectively, and both ends of the central shaft 4 are threadedly connected with a radial cone end 41, and both ends of the central shaft 4 are provided with a radial cone end 41, and the radial cone end 41 is installed with a locking piece 42, and the locking piece 42 is used to lock the position of the radial cone end 41, and one of the lifting frames 3 is fixedly installed with a main drive motor 5, and the central shaft 4 is detachably connected to the output end of the main drive motor 5.

[0034] Specifically, conical diametrical cone ends 41 are provided at both ends of the central axis 4. As the diametrical cone ends 41 move axially, the diameter corresponding to the position supporting the cable reel also changes. By moving the diametrical cone ends 41, the axis of the cable reel is made collinear with the central axis 4.

[0035] In this way, the conical end 41 allows cable reels of various specifications to maintain their axes colinear with the central axis 4 during rotation, which facilitates the rotation of the cable reel and enables the cable retracting structure to be adapted to the use of cable reels of various specifications.

[0036] In some feasible ways, the support frame 1 includes a bottom plate, on which two C-shaped channel steel-shaped support columns are installed. To facilitate movement and fixed position, the moving wheel 2 is a universal wheel with brakes. The lifting frame 3 is a rectangular plate-shaped lifting frame 3 installed between the two support columns. Two rectangular blocks are fixedly connected on both sides of the lifting frame 3, and the rectangular blocks can be slidably embedded in the grooves of the support columns. A bearing seat 331 is provided at the upper end of the lifting frame 3, and both ends of the central shaft 4 are detachably installed on the bearing seat 331. A lifting drive 31 is installed below the lifting frame 3 to drive the lifting frame 3 to lift the wheel disc. The lifting drive 31 can be selected as an electric push rod, a cylinder or a hydraulic cylinder;

[0037] The diametric cone end 41 is conical. To facilitate rotation, a hexagonal prism can be fixedly installed on the bottom end of the diametric cone end 41 to facilitate rotation by a wrench, etc. The locking piece 42 can be set as a set screw to fix the position of the diametric cone end 41. The diametric cone end 41 can support a cable reel whose center ring diameter is within the range from the small diameter at the bottom end to the large diameter at the bottom end of the diametric cone end 41. The output end of the main drive motor 5 is fixedly connected to the central rotating part of the bearing seat 331. When the central shaft 4 is installed on the bearing seat 331, the main drive motor 5 drives it to rotate.

[0038] When in use, the center shaft 4 is removed, and inserted into the center ring of the cable reel, and the diametrical cone ends 41 at both ends are adjusted to make the center shaft 4 and the center ring collinear, that is, the diametrical cone ends 41 at both ends are tightened toward the cable reel, and the lifting frame 3 is driven to a suitable height, so that the diametrical cone ends 41 are inserted into the bearing seat 331 and fixed, and the lifting frame 3 is driven to rise to lift the cable reel off the ground.

[0039] As a specific implementation of a cable laying and cable retracting structure provided in the application, please refer to Figure 2 The locking member 42 includes a check thread arranged at both ends of the central axis 4, and the rotation direction of the check thread is opposite to the rotation direction of the thread corresponding to the diametrical cone end 41 close to it. A check screw 421 is threadedly connected to the check thread position, and the end of the check screw 421 close to the diametrical cone end 41 is a round tube with an inner diameter larger than the central axis 4.

[0040] In general, by setting the check screw 421, the position of the diametric cone end 41 is restricted. The thread rotation direction of the check screw 421 is opposite to that of the diametric cone end 41. When the diametric cone end 41 is loosened in the direction away from the cable reel, the friction check screw 421 rotates synchronously, causing the check screw 421 to move toward the cable reel, thereby restricting the diametric cone end 41.

[0041] In some feasible embodiments, the non-return spiral tube 421 includes a threaded section and a round tube section, and the outer diameter of the threaded section of the non-return spiral tube 421 on the central shaft 4 is smaller than the inner diameter of the diametrical cone end 41 so that the diametrical cone end 41 can be installed.

[0042] Furthermore, the central shaft 4 is a telescopic rod, a positioning pin hole is opened on the central shaft 4, and a positioning pin is arranged at the telescopic position of the central shaft 4.

[0043] It should be understood that by configuring the central axis 4 as a telescopic rod, the central axis 4 can be adapted to the use of cable reels with different axial widths.

[0044] In some feasible embodiments, the central axis 4 is a three-section structure, with round tubes at both ends and a cylinder in the middle. The cylinder is provided with a plurality of positioning pin holes, and a positioning pin can be slidably installed at one end of the round tube close to the cylinder.

[0045] As another specific implementation of a cable laying and cable retracting structure provided in the application, a fixing hole 44 is axially opened near the outer side of the conical end 41 .

[0046] It should be understood that by providing the fixing hole 44, when a wheel disc is installed that has insufficient friction force formed by the conical end 41 to drive the wheel disc, it can be fixed by tying a steel cable between the fixing hole 44 and the wheel disc spokes.

[0047] As a specific implementation of a cable laying and cable retracting structure provided in the application, please refer to Figure 1 The lifting frame 3 includes a driving frame 32 , which is slidably mounted on the supporting frame 1 , an adapting frame 33 is hingedly connected to the upper end of the driving frame 32 , and the central shaft 4 is inserted and mounted on the adapting frame 33 .

[0048] It should be understood that the two lifting frames 3 are driven by a lifting drive 31 respectively, and there may be certain differences. By setting the adapter frame 33 to be hinged, the adapter frame 33 part has a certain activity space, which reduces the torsional force on the central shaft 4 and improves the service life of the central shaft 4 and the lifting drive 31.

[0049] Furthermore, the adapter frame 33 includes a bearing seat 331 , the central shaft 4 is provided with a threaded hole, and the bearing seat 331 is bolted to the central shaft 4 .

[0050] It should be understood that by providing a bolt connection, the connection strength between the central shaft 4 and the bearing seat 331 is increased, and the possibility of the adapter frame 33 coming out when rotating is reduced.

[0051] Furthermore, the output end of the main drive motor 5 is connected to the central shaft 4 via a universal joint.

[0052] It should be understood that by providing a universal joint connection, the output end of the main drive motor 5 can adapt to the rotation of the adapter bracket 33.

[0053] In some feasible embodiments, a connecting shaft is fixedly connected to one end of the bearing seat 331 away from the central axis 4, and the connecting shaft is connected to the output end of the main drive motor 5 through a universal joint.

[0054] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
