Description

Technical Field

[0001] The invention relates to the technical field of cable laying, in particular to a portable cable laying device. Background Art

[0002] Traditional cable laying mostly adopts manual laying, that is, a winch is applied to the cable end to pull the cable so that the cable slides on the bracket. However, this laying method will cause the cable insulation layer to slide and wear against the bracket during the installation process, thus damaging the cable, which not only reduces the service life of the cable, but also makes it easy to cause leakage risk.

[0003] In view of this situation, a method of installing rollers on the bracket has appeared in the prior art, so that the cable can be laid by rolling with the rollers on the bracket during the laying process. When the cable is pulled around the radial side wall of the roller on the bracket, the roller rotates around its own axis. However, due to the different diameters of the laid cables and the fixed height of the roller guide on the bracket, when the diameter of the laid cable is greater than the axial height of the roller, the cable is easy to cross laterally from the upper end of the roller and detach when being pulled. It is also difficult to fix the cable to the roller on the bracket, resulting in the cable dragging on the ground, and the outer insulation layer of the cable sliding in contact with the ground, which is easy to damage the outer insulation protective layer of the cable.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] First embodiment, this embodiment provides a convenient cable laying device, such as Figure 1 and Figure 2 As shown, it includes: a positioning base 1, and a positioning piece is provided on the circumferential side wall of the positioning base 1; specifically, the positioning piece includes two extension frames 12 and one extension frame 2 14, and the two sides of one end of the positioning base 1 away from the supporting part are respectively hinged with the two extension frames 12, a sliding groove 11 is provided at the bottom end of the positioning base 1, an I-shaped sliding shaft 142 is rotatably provided at the bottom end of the supporting part, and a guide sliding hole 141 is provided on the extension frame 2 14 for sliding engagement with the I-shaped sliding shaft 142, and the extension frame 2 14 is slidably engaged with the sliding groove 11.

[0037] The extension frame 12 is rotated around the position where it is hinged to the positioning base 1, so that the two extension frames 12 are rotated and adjusted from a state of being parallel to each other to a V-shaped structure or a straight-line structure, thereby expanding the support range of the positioning base 1 and enhancing the support stability. In addition, according to the terrain, the extension frame 12 is selectively rotated so that its landing point is located on a flat area as much as possible. At the same time, the guide sliding hole 141 of the extension frame 2 14 slides horizontally along the outer wall of the I-shaped sliding shaft 142. After the end of the extension frame 2 14 is separated from the sliding groove 11, the guide sliding hole 141 of the extension frame 2 14 rotates with the I-shaped sliding shaft 142 as the rotation center, and the direction of the extension frame 2 14 is adjusted so that its landing point is located on a flat area as much as possible.

[0038] At the same time, an extension part is extended to both sides at the end of the extension frame 14, and the end bottom wall of the extension part and the end bottom wall of the extension frame 12 are fixed with an embedded plug 13. After the extension frame 12 and the extension frame 14 are rotated and adjusted to a flat section, the ends of the extension frame 12 and the extension frame 2 are tamped with a knocking tool (hammer), which can tamp the embedded plug 13 below the ground surface, ensuring that the positions of the extension frame 12 and the extension frame 2 14 are no longer adjusted at will, affecting the supporting stability of the positioning base 1.

[0039] A support part extends from the side wall of one side of the positioning base 1, and a tray 15 is fixed on the upper end face of the support part. A support beam 2 is provided on the upper end face of the tray 15. The support beam 2 rotates around the axis of the tray 15, and a laying frame is provided at the end of the support beam 2. Specifically, the laying frame includes at least two turntables 3, one of which is connected to the axial side wall by a threaded adjustment rod 32, and the other turntables 3 are provided with threaded holes threadedly connected to the threaded adjustment rod 32. An elastic rod 31 is provided between the edge positions of the opposite side walls of two adjacent turntables 3. There are multiple elastic rods 31, which are evenly distributed along the circumference of the turntable 3. The elastic rod 31 rotates around the axis of the turntable 3 as the rotation center to form a rotating guide that can fit the outer insulation layer of the cable. According to the diameter of the cable, the support beam 2 is rotated around the rotation position with the tray 15 to adjust the gap between the two laying members, that is, to adjust the clamping space between the two rotating guides. The width of the clamping space after adjustment can be close to the diameter of the cable. Two rotating guides are used to clamp the outer wall of the cable. When the cable is pulled for laying, the cable slides along the radial outer wall of the elastic rod 31. The elastic rod 31 rotates with the threaded adjustment rod 32 as the rotation center, which meets the traction of the cable laying and reduces the friction resistance during the traction process.

[0040] like Figure 1 As shown, when the axis of the turntable 3 is vertically distributed, two laying racks are provided, and the rotating guides of the two laying racks are symmetrically attached to the outer insulation layer of the cable.

[0041] The elastic rod 31 is bent into an arc structure toward the axis of the turntable 3. According to the diameter of the cable, the turntable 3 threadedly connected to the threaded hole of the threaded adjustment rod 32 is rotated to translate the turntable 3 toward or away from the side of the turntable 3 rotatably connected to the threaded adjustment rod 32, thereby adjusting the bending range of the elastic rod 31.

[0042] When the two turntables 3 are adjusted to be away from each other in the vertical direction, the two ends of the elastic rod 31 tend to be straightened, so the diameter of the bending arc of the elastic rod 31 becomes larger, which is suitable for cables with slightly larger diameters. The two turntables 3 are adjusted to be away from each other and the gap between the two turntables 3, that is, the longitudinal distance between the two turntables 3, is increased, which can prevent cables with large diameters from falling from the upper end surface of any uppermost turntable 3 onto the ground, causing a dragging phenomenon.

[0043] When the two turntables 3 are adjusted to be close to each other in the vertical direction, the two ends of the elastic rod 31 are further bent, so the diameter of the bending arc of the elastic rod 31 becomes smaller, which is suitable for cables with slightly smaller diameters and can be wrapped around the outer wall of the cable to the maximum extent, thereby preventing the cable from jumping up and down and falling from the upper end surface of any uppermost turntable 3 to the ground, causing a dragging phenomenon.

[0044] When laying cables, according to the laying requirements, a corresponding number of positioning bases 1 are selected as the supporting basis, for example, one is placed every 3-5 meters, and multiple rotating guides are clamped on opposite sides of the cable and lifted up to avoid dragging on the ground during cable traction and laying.

[0045] Specifically, there are two laying frames, and the lowermost turntable 3 is rotatably set on the upper side wall of the end of the support beam 2 away from the pallet 15. There are two support beams 2, and both are rotatably set on the upper end surface of the pallet 15; it also includes a limit frame, which is used to prevent the two support beams 2 from rotating at will. The limit frame includes two plug posts 21, and the support beam 2 is located at one end of the pallet 15 and has a slot that is plugged into the plug posts 21; a connecting rod 211 is fixed between the top ends of the side walls of the two plug posts 21, and a block 212 is fixedly connected to the bottom wall of the connecting rod 211, and the side walls on both sides of the block 212 are both conical structures, and the outer wall of one end of the support beam 2 that is rotatably connected to the pallet 15 is provided with a plurality of tooth blocks 22, and the conical structure is inserted in the gap between two adjacent tooth blocks 22 on the outer wall of the same support beam 2. Figure 1 , Figure 3 and Figure 4 As shown, lift the connecting rod 211 upwards, disengage the two plug posts 21 from the slots of the support beam 2, and disengage the two conical structures of the clamping block 212 from the gap between the two adjacent tooth blocks 22 of the two support beams 2, so that the support beam 2 loses its limit and can rotate freely around the rotation position of the tray 15, thereby adjusting the gap between the two laying racks. After adjustment, insert the plug post 21 into the slot, and at the same time, the conical structure of the clamping block 212 is clamped into the gap between the two adjacent tooth blocks 22 at the corresponding position, locking the support beam 2 so that it will not rotate freely.

[0046] In a further embodiment, during the actual laying of cables, there are situations where multiple cables are laid simultaneously. For this purpose, multiple turntables 3 are provided and coaxially distributed, and elastic rods 31 are provided between the edges of the opposite side walls of two adjacent turntables 3 to form multiple rotating guides. Figure 5 As shown, when multiple cables need to be laid at a time, two rotating guides on the same horizontal plane form a group, which are used to clamp the outer wall of a single cable relatively. Multiple groups of rotating guides can separate multiple cables in parallel to avoid entanglement during the traction and laying process.

[0047] In addition, according to the diameter of the cable, the turntable 3 threadedly connected to the threaded hole of the threaded adjustment rod 32 is adjusted to be closer to or away from one side of the turntable 3 rotatably connected to the threaded adjustment rod 32 by rotating the threaded adjustment rod 32, so as to adjust the bending amplitude of the elastic rod 31 to meet the traction requirements of cables of different diameters. The upper side wall of the edge of the turntable 3 located on the lower side of each group of rotating guide members and the bottom of the elastic rod 31 form an arc-shaped support portion, which can be against the bottom end of the outer wall of the cable, thereby generating a supporting force for cables of different diameters and preventing the cables from falling to the ground, thereby being able to adapt to cables of different diameters.

[0048] The second embodiment is different from the first embodiment in that Figure 6 As shown, when the axis of the turntable 3 is horizontally distributed, there is one laying rack, and the rotating guide is supported on the lower side wall of the outer insulation layer of the cable. There is one laying rack, two turntables 3, and the axis of the turntable 3 is horizontally distributed, and there is one supporting beam 2, and one of the turntables 3 is rotatably connected to the side of the end of the supporting beam 2. One of the turntables 3 can rotate relative to the side wall of the end of the supporting beam 2, and the cable passes over the uppermost elastic rod 31 of the rotating guide. In this process, the need for the cable to be laid in the air can be met.

[0049] Similarly, according to the diameter of the cable, by rotating the threaded adjustment rod 32, the turntable 3 threadedly connected to the threaded hole of the threaded adjustment rod 32 is adjusted to move closer to or away from the side of the turntable 3 rotatably connected to the threaded adjustment rod 32, so as to adjust the bending amplitude of the elastic rod 31, so as to meet the traction requirements of cables of different diameters. When the two turntables 3 are moved away from each other for translation adjustment, the two ends of the elastic rod 31 tend to be straightened, so the diameter of the bending arc of the elastic rod 31 becomes larger, and it is suitable for cables with slightly larger diameters. When the two turntables 3 are moved closer to each other for translation adjustment, that is, the horizontal distance between the two turntables 3 is shortened, and the two ends of the elastic rod 31 are further bent, so the diameter of the bending arc of the elastic rod 31 becomes smaller, and it is suitable for cables with slightly smaller diameters, and it can be wrapped on the outer wall of the cable to the maximum extent.

[0050] In order to prevent the cable from jumping during traction, it slides laterally from the upper end of the turntable 3, such as Figure 7 , Figure 8 and Fig. 9As shown, the anti-slip frame is provided with a longitudinal support part 1 4, a transverse limiting part 41 and a longitudinal support part 2 42. The transverse limiting part 41 is located between the tops of the longitudinal support part 1 4 and the longitudinal support part 2 42. The bottom end of the side wall of the longitudinal support part 1 4 is rotatably connected to a multi-cornered column 44. The end of the threaded adjustment rod 32 is provided with a polygonal groove for inserting the multi-cornered column 44. The bottom end of the longitudinal support part 2 42 extends close to the upper end of the radial side wall of a turntable 3 that is rotatably connected to the side wall of the end of the supporting crossbeam 2. The multi-cornered column 44 is inserted into the polygonal groove, and the longitudinal support part 1 4 rotates around the rotation position of the multi-cornered column 44, and the transverse limiting part 41 is pressed on the upper end of the outer wall of the cable pulled through the elastic rod 31. The self-weight of the entire anti-slip frame is used to press down on the cable to prevent the cable from jumping up and down during the pulling process, which affects the transportation stability.

[0051] A circular arc-shaped card plate 43 is provided at the bottom end of the second longitudinal support part 42, and a matching notch is provided on the bottom wall of the card plate 43. A radial side wall of a turntable 3 that is rotatably connected to the side wall of the end of the supporting crossbeam 2 is rotatably fitted with the inner wall of the matching notch. The card plate 43 uses the matching notch to rotatably fit with the turntable 3 on the corresponding side, which can not only support the rotation of the second longitudinal support part 42, but also avoid a gap between the second longitudinal support part 42 and the upper end of the turntable 3, so that the cable may slip off the elastic rod 31 horizontally.

[0052] The lateral limiting portion 41 bends upward to form an arc structure, and a plurality of balls are rotatably embedded in the bottom wall of the arc structure. The arc structure can better match the outer wall of the cable, and the balls can roll and fit with the upper end of the outer wall of the cable to reduce the friction between the bottom wall of the arc structure and the cable.

[0053] In summary, two laying racks or one laying rack is selected according to the cable laying support requirements. The rotating guides of the two laying racks are symmetrically fitted on the outer insulation layer of the cable. When the cable is pulled, the outer insulation layer of the cable rolls and fits with the rotating guide. When one laying rack is selected, the rotating guide is supported on the lower side wall of the outer insulation layer of the cable. Regardless of whether there are two or one laying racks, the whole structure is simple, easy to carry, and can lift the cable into the air while reducing friction during laying and pulling.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
