Description

Technical Field

[0001] The utility model relates to the technical field of electric power construction equipment, in particular to a cable laying device. Background Art

[0002] Power cables are usually made of one or more mutually insulated conductors and an outer insulating protective layer. In order to facilitate transportation and storage, the cable is generally wound on a reel. When in use, the support shaft is passed through the middle through-hole of the pay-off reel; and a pair of pay-off frames are placed on both ends of the support shaft respectively. The two ends of the support shaft are lifted up with a jack so that the pay-off reel is lifted off the ground. The free end of the cable is pulled to drive the reel to rotate on the support shaft, so that the cable is detached from the reel.

[0003] The current technical problems are: the sizes of the middle through holes of different specifications of wire pay-off reels are also different. In order to facilitate the installation of the support shaft through the through hole, the size of the middle through hole of the existing wire pay-off reel is too large, so that when the support shaft supports the wire pay-off reel, the support shaft is at the top of the through hole of the wire pay-off reel, and the axis of the support shaft is not consistent with the axis of the wire pay-off reel, causing eccentric rotation when the wire pay-off reel rotates, which can easily cause violent shaking of the wire pay-off reel and the wire pay-off frame. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide a cable laying device to solve the technical problem that the existing cable pay-off rack cannot well fix the pay-off reels with through holes of different diameters.

[0040] like Figure 1 and Figure 2 As shown, a cable laying device includes:

[0041] A pay-off frame 1 and a support shaft 2 rotatably connected to the pay-off frame 1, one end of the support shaft 2 passes through the through hole of the pay-off drum and supports the pay-off drum;

[0042] A plurality of support plates 14 are arranged in an array on the outer circumference of the support shaft 2 with the axis of the support shaft 2 as the center. The support plates 14 extend along the length of the support shaft 2 and have support surfaces formed on their surfaces. The plurality of support surfaces form a virtual cylindrical surface for supporting the inner wall of the through hole of the pay-off reel. The axis of the virtual cylindrical surface coincides with the axis of the support shaft 2.

[0043] A driving component for driving all support plates 14 to move in the radial direction of the support shaft 2 to adjust the radius of the virtual cylindrical surface;

[0044] The above technical solution can be used to fix cable pay-off reels with holes of different apertures. When in use, the positions of all support plates 14 are adjusted by the driving components, so that the support plates 14 move outward or inward in the radial direction of the support shaft 2, so that the radius of the virtual cylindrical surface formed by the support plates 14 increases or decreases, so that the radius of the virtual cylindrical surface is adapted to the size of the pay-off reel through-hole that needs to be fixed. After the pay-off reel through-hole is inserted into the support shaft 2 and the support plate 14, the support surface on the surface of the support plate 14 can fully fit the pay-off reel through-hole, thereby ensuring that the axis center line of the support shaft 2 and the axis center line of the pay-off reel through-hole coincide with each other, so that the pay-off reel will not rotate eccentrically when rotating, avoiding violent shaking of the pay-off reel and the pay-off frame 1, and preventing the danger of the cable reel escaping.

[0045] like Figure 3 and Figure 4 As shown, in this embodiment, the driving component includes: a first slider 13 connected to the inner side of the support plate 14 at one end, the first slider 13 slidably engaged with the first slide groove 12 opened in the surface of the support shaft 2; an adjusting structure for adjusting the position of the first slider 13 relative to the first slide groove 12; specifically, the adjusting structure includes at least two adjusting parts arranged relative to the support shaft 2. The adjusting part includes: a second slider 15 with a threaded groove 16, the second slider 15 slidably engaged with the second slide groove 17 opened in the support shaft 2; a linking member 21 rotatably connected to the second slider 15 at one end, and the other end of the linking member 21 is rotatably connected to the first slider 13; an adjusting mechanism for adjusting the position of the second slider 15 relative to the second slide groove 17; further, the adjusting mechanism includes: a first threaded rod 18 rotatably arranged at one end in the second slide groove 17, the other end of the first threaded rod 18 is threadedly connected to the threaded groove 16 opened in the second slider 15; a locking member for preventing the first threaded rod 18 from rotating relative to the second slider 15;

[0046] The above technical solution can be used to specifically adjust the radius of the virtual cylindrical surface formed by the support plate 14. When in use, the first threaded rod 18 can be rotated to cooperate with the threaded groove 16 to drive the second slider 15 to slide along the second slide groove 17. When the second slider 15 moves in the direction away from the support shaft 2, the second slider 15 will drive the first slider 13 to retract into the first slide groove 12 through the linkage 21, thereby driving the support plate 14 connected to the first slider 13 to move inward in the radial direction of the support shaft 2, thereby reducing the radius of the virtual cylindrical surface formed by the support plate 14; conversely, when the second slider 15 moves in the direction close to the support shaft 2, the radius of the virtual cylindrical surface formed by the support plate 14 will increase, thereby achieving adjustment to adapt to the fixation of the through holes of the pay-off reels of different specifications.

[0047] like Figure 3 and Figure 4As shown, in this embodiment, the device further includes: connecting frames 3 provided at both ends of the support shaft 2; an end shaft 4 connected to the connecting frame 3, the end shaft 4 rotatably engaged with a rotation groove 5 provided in the pay-off frame 1, and a locking component including: a second threaded rod 19 connected to the first threaded rod 18 at one end, the other end of the second threaded rod 19 passing through a through groove provided on the surface of the end shaft 4; and a locking nut 20 connected to the second threaded rod 19.

[0048] The above technical solution can limit the rotation of the first threaded rod 18. When the radius of the virtual cylindrical surface formed by the support plate 14 is adjusted appropriately, the locking nut 20 is rotated to make it fit tightly against one end of the end shaft 4, thereby preventing the first threaded rod 18 from rotating due to accidental touch, and avoiding fluctuations in the radius of the virtual cylindrical surface formed by the support plate 14.

[0049] like Figure 3 As shown, in this embodiment, the device further includes: a hinge 8 connected to the pay-off frame 1 at one end; a limiting plate 9 connected to the other end of the hinge 8, the limiting plate 9 also having a rotation slot 5, and a complete rotation slot 5 can be formed by combining the limiting plate 9 with the pay-off frame 1; a positioning hole 10 is formed at one end of each of the limiting plate 9 and the pay-off frame 1, and a positioning member 11 is provided in the positioning hole 10;

[0050] The above technical solution can facilitate the installation and disassembly of the support shaft 2. When the support shaft 2 needs to be installed, push the limit plate 9 to rotate it around the hinge 8, thereby opening the rotation groove 5, and place the end shafts 4 at both ends of the end shaft 4 into the rotation groove 5. Close the limit plate 9 again and use the positioning parts 11 such as bolts to fix the positioning holes 10 to complete the installation.

[0051] like Figure 3 As shown, in this embodiment, the inner wall of the rotating groove 5 is provided with a limiting protrusion 6, and the limiting protrusion 6 is slidably engaged with the limiting groove 7 provided on the surface of the end shaft 4;

[0052] The above technical solution can prevent the end shaft 4 from detaching from the rotating groove 5. By setting the limiting protrusion 6 and the limiting groove 7, on the one hand, it can ensure that the end shaft 4 is more stable when rotating, and on the other hand, it can ensure that the end shaft 4 will not detach from the rotating groove 5, thereby improving the stability of the structure.

[0053] Furthermore, in this embodiment, the surface of the support plate 14 is provided with anti-slip grooves to increase the friction coefficient with the inner wall of the through hole of the pay-off reel;

[0054] The above technical solution can avoid slipping between the surface of the support plate 14 and the inner wall of the through hole of the pay-off drum, thereby ensuring stability during pay-off.

[0055] When the second slider 15 moves in the direction away from the support shaft 2, the second slider 15 will drive the first slider 13 to retract into the first slide groove 12 through the linkage 21, thereby driving the support plate 14 connected to the first slider 13 to move inward in the radial direction of the support shaft 2, thereby reducing the radius of the virtual cylindrical surface formed by the support plate 14, so that the radius of the virtual cylindrical surface is adapted to the size of the cable reel through hole to be fixed. After the cable reel through hole is inserted into the support shaft 2 and the support plate 14, the support surface of the support plate 14 can fully fit the cable reel through hole, thereby ensuring that the axis line of the support shaft 2 and the axis line of the cable reel through hole coincide with each other, so that the cable reel will not rotate eccentrically when rotating, avoiding violent shaking of the cable reel and the cable reel frame 1, and preventing the cable reel from being out of danger.
