[0001] This utility model relates to the field of cable winding and unwinding technology, and more specifically, to a cable winding and unwinding device for substation engineering construction. Background Technology

[0002] In substation construction, the cable winding and unwinding not only affects the construction progress but also directly impacts the cable quality and subsequent performance. Therefore, employing appropriate cable winding and unwinding devices is crucial.

[0003] Patent CN213536895U discloses a cable winding and unwinding device for substation construction. The device is moved to a designated location using casters, and the height of the winding reel is adjusted by extending and retracting a second telescopic column via a hydraulic system. One end of the cable is then passed through an auxiliary support base, and a rotary motor is activated via a control panel to complete the cable winding and unwinding process. However, in this cable winding and unwinding device, the height of the winding reel is adjusted via a telescopic column. During the cable winding and unwinding process, the telescopic column may retract downwards, affecting the normal winding and unwinding of the cable. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a cable winding and unwinding device for substation engineering construction, so that the winding assembly remains stable after the height is adjusted.

[0005] A cable winding and unwinding device for substation construction includes a support assembly and a winding assembly; the upper end face of the support assembly is an inclined surface, and the lower end face of the winding assembly is an inclined surface adapted to it; the winding assembly is installed at different positions on the upper end face of the support assembly to form different heights of the winding assembly.

[0006] The upper end face of the bracket assembly is provided with a sliding groove, and the lower end face of the winding assembly is provided with a sliding strip adapted to the sliding groove; the upper end face of the bracket assembly is provided with a plurality of blind holes for fixing the winding assembly.

[0007] Furthermore, the support assembly is wedge-shaped, with two parallel grooves on its upper surface.

[0008] Furthermore, the groove is wider inside and narrower outside.

[0009] Furthermore, each of the grooves is provided with several blind holes on its outer side.

[0010] Furthermore, the winding assembly includes a base plate, two supports fixed to the base plate, and a winding disc rotatably connected to the two supports; a motor is arranged on one side of the winding disc, and the output end of the motor is connected to the winding disc;

[0011] The base plate is inclined, and its lower end face has the same inclination as the upper end face of the support assembly; a sliding strip is also fixed to the lower end face of the base plate, and the sliding strip is adapted to the sliding groove; the base plate is also provided with a through hole, and a positioning rod is inserted into the blind hole after passing through the through hole to fix the base plate.

[0012] Furthermore, the distance between two through holes on the same horizontal line is the same as the distance between two blind holes on the same horizontal line.

[0013] Furthermore, the positioning rod is a screw, and the inner wall of the blind hole is provided with threads that are compatible with the screw.

[0014] Furthermore, a washer is also sleeved on the positioning rod. The upper end face of the washer is a plane, and the lower end face of the washer is an inclined plane, the inclination of which matches the inclination of the upper end face of the base plate.

[0015] Furthermore, the motor is mounted on a placement platform.

[0016] Furthermore, an auxiliary support structure is also fixedly connected to the base plate; the auxiliary support structure includes two rods, a support roller, and a limiting strip;

[0020] The cable winding and unwinding device used in the construction of this substation project has a wedge-shaped support assembly with several equally spaced blind holes on its upper surface. When the winding assembly is fixed to the blind holes at different heights, it can form winding assemblies of different heights, thereby adapting to the operational needs of winding and unwinding cables at different heights during the construction of the substation project.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] like Figures 1-6 As shown, this embodiment provides a cable winding and unwinding device for substation construction, including a support assembly 1 and a winding assembly. The upper end surface of the support assembly 1 is an inclined surface, and the lower end surface of the winding assembly is an inclined surface adapted to it. The winding assembly is installed at different positions on the upper end surface of the support assembly 1, and the winding assembly can be adjusted to different heights.

[0039] In this embodiment, the support assembly 1 is wedge-shaped, and a groove 11 is provided on the upper end surface of the support assembly 1. Correspondingly, a slide bar that matches the groove 11 is provided on the lower end surface of the winding assembly. A plurality of blind holes 12 are provided on the upper end surface of the support assembly 1 for fixing the winding assembly.

[0040] Specifically, such as Figures 1-3 As shown, the upper surface of the support assembly 1 has two parallel sliding grooves 11. The sliding grooves 11 are wider on the inside and narrower on the outside. When the slider of the winding assembly is inserted into the sliding groove 11, it can effectively prevent the winding assembly from detaching from the support assembly 1. Several blind holes 12 are also provided on the outside of each sliding groove. More specifically, the support assembly 1 has two rows of blind holes, each row of blind holes being located on the outside of the sliding groove 11. In each row of blind holes, the distance between two adjacent blind holes 12 is the same.

[0041] In this embodiment, as Figure 1 , Figures 4-6 As shown, the winding assembly includes a base plate 2, two supports 3 fixed to the base plate 2, and a winding reel 4 rotatably connected to the two supports. A motor 5 is mounted on one side of the winding reel 4, and the output end of the motor 5 is connected to the winding reel 4. When the motor 5 is running, it can drive the winding reel 4 to rotate, thereby performing cable winding and unwinding operations. The motor 5 is mounted on a placement platform 51, which is fixed to the upper surface of the base plate 2. The base plate 2 is an inclined plate structure, and the supports are vertically arranged plate structures.

[0042] Specifically, the base plate 2 is inclined, with its lower end face having the same inclination as the upper end face of the support assembly 1. A slider 21 is also fixed to the lower end face of the base plate 2. Two sliders 21 are arranged parallel to each other, and the distance between the two sliders 21 is the same as the distance between the two sliding grooves 11. The shape of the slider 21 matches the sliding groove 11. The base plate 2 also has a through hole 22. A positioning rod 6 passes through the through hole 22 and extends into the blind hole 12, which can fix the base plate 2 to the support assembly 1. To facilitate the movement of the slider 21 within the sliding groove 11, the size of the slider 21 is designed to be slightly smaller than the outline of the sliding groove 11. A ball bearing 23 is also embedded in the slider 21. The ball bearing is a spherical object, with a small portion protruding from the surface of the slider, preventing it from falling off and aiding in the sliding of the slider 21.

[0043] Furthermore, the spacing between two through holes 22 on the same horizontal line is the same as the spacing between two blind holes 12 on the same horizontal line. Four through holes 22 are provided on the base plate, two on each side, with the positioning rod 6 passing through the two upper through holes 22 and fixed to the bracket assembly 1.

[0044] More specifically, the positioning rod 6 is a screw, and the inner wall of the blind hole 12 is threaded to match the screw. A washer 7 is also fitted onto the positioning rod 6. The upper surface of the washer 7 is flat, abutting against the nut at the top of the screw; the lower surface of the washer 7 is inclined, its inclination matching the inclination of the upper surface of the base plate 2. The design of the washer 7 allows for a more stable fixation of the base plate 2 to the bracket assembly 1. By using the positioning rod 6 to fix the base plate 2 to the blind holes 12 at different positions on the bracket assembly 1, winding assemblies of different heights can be formed, thus meeting the operational needs of cable winding and unwinding at different heights during substation construction.

[0045] In this embodiment, an auxiliary support structure 8 is also fixedly connected to the base plate 2. The auxiliary support structure 8 includes two support rods 81, a support roller 82, and a limiting strip 83. When the cable is being wound up or down, the cable extends from the support roller 82 and passes through the gap between the support roller 82 and the limiting strip 83, which can effectively prevent the cable from moving excessively.

[0046] Among them, such as Figure 6 and Figure 7As shown, each support rod 81 includes a base rod 811 connected to the blind hole 12, a connecting rod 812, and a sleeve 813. The outer walls of the base rod 811 and the connecting rod 812 are provided with threads in opposite directions. The two ends of the sleeve 813 are respectively screwed to the top end of the base rod 811 and the bottom end of the connecting rod 812. The connecting rod 812 is rotatably connected to a connecting plate 814. A support roller 82 is rotatably connected between the two connecting plates 814 through a bearing. Limiting strips 83 are detachably connected to the top ends of the two connecting plates 814. The limiting strips 83 are upwardly curved arc rods, and first connecting ears 831 are fixed to both ends of each. The first connecting ears have connecting holes, and bolts can be used to fix the first connecting ears to the connecting plates, thereby realizing the fixation of the limiting strips 83 and the connecting plates 814.

[0047] Connecting rod 812 is rotatably connected to connecting plate 814, such as Figure 7 As shown, the lower end of the connecting plate 814 is a disc-shaped protrusion 815, which is thicker on the outside and thinner on the inside. Correspondingly, the top of the connecting rod 812 is provided with a matching recess. When the position of the connecting plate 814 is fixed, the connecting rod 812 can rotate around the protrusion 815 as an axis without detaching from the connecting rod 812.

[0048] The auxiliary support structure 8 is designed to serve as a fixing structure for fixing the base plate 2 to the bracket assembly 1, and also to provide auxiliary support for the cable during cable winding and unwinding to prevent the cable from getting tangled.

[0049] Furthermore, a gasket 7 is provided between the sleeve 813 and the base plate 2 to maintain the stability and fixation of the auxiliary support structure 8.

[0050] In this embodiment, handles 13 are provided on the left and right sides of the bracket assembly 1 to facilitate moving the bracket assembly 1. When it is necessary to move this cable retractor, the device can be moved onto a flatbed cart or other mobile trolley.

[0051] When the cable reeling device needs to be fixed, a second connecting ear 14 is provided on the bottom side of its bracket assembly 1. When the bracket assembly is moved to the required position, anchor rods or bolts can be used to fix the bracket assembly to the ground.

[0052] The cable winding and unwinding device for substation construction provided in this embodiment has a wedge-shaped support component 1 with several equally spaced blind holes 12 on its upper surface. When the winding component is fixed to the blind holes 12 at different heights, winding components of different heights can be formed, thus meeting the operational needs of winding and unwinding cables of different heights in substation construction.

[0053] The slider 21 of the winding assembly is inserted into the groove 11 of the bracket assembly 1 and can slide along the groove 11, so that the through hole 22 can correspond to the blind hole 12 at different heights. After selecting the position of the blind hole 12 at a suitable height, the two positioning rods 6 are passed through the two upper through holes 22, the washer 7 and the corresponding blind hole 12 in the base plate in sequence, so as to fix the base plate on the bracket assembly 1 and form the required winding assembly height.

[0054] To further reinforce the stability of the winding assembly, auxiliary support structures 8 are connected to the two lower through holes 22 in the base plate. The auxiliary support structures 8 are designed to serve both as a fixing structure for securing the base plate 2 to the bracket assembly 1 and as an auxiliary support for the cable during cable winding and unwinding to prevent the cable from tangling.

[0055] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
