Description

Technical Field

[0001] The utility model belongs to the technical field of cable tensioning and relates to a stable cable tensioning device. Background Art

[0002] There are two main ways to install cables: high-altitude suspension installation and underground burial installation. When the cables are suspended in the air through cable brackets, the cables will relax and bend under their own gravity and external forces, such as wind. In order to ensure the working stability and safety of the high-altitude suspended cables, it is necessary to apply a moving tension force to the cables to keep the cables in a suitable tension state.

[0003] The existing cable stabilization tensioning device usually sets a tensioning drum or tensioning wheel on the cable support, and applies tensioning force to the cable through the tensioning drum or tensioning wheel to tension the cable. However, the tensioning force applied to the cable by the tensioning structures such as the existing tensioning drum and tensioning wheel is difficult to adjust, and the body or rim of the tensioning drum and tensioning wheel will slip after a long period of tensioning operation, resulting in a change in the tension state of the cable.

[0004] Therefore, in view of the above-mentioned technical problems existing in the existing cable tensioning structure, the utility model discloses a cable stable tensioning device. Utility Model Content

[0031] The tension sleeve 2 is fixedly sleeved on both ends of the cable 1, and the tension wheel 3 and the pressure wheel 4 are installed on the cable frame through the fixing part 5. The sliding part 22 at the top of the tension sleeve 2 is pressed toward the tension wheel 3 by the rim of the pressure wheel 4, and the rim of the pressure wheel 4 is slidably connected with the sliding part 22, which will not affect the subsequent linear movement of the tension sleeve 2.

[0032] An external tooth portion 31 is provided on the outside of the tensioning wheel 3, and the external tooth portion 31 is meshedly connected with the locking portion 21 at the bottom of the tensioning sleeve 2.

[0038] After the tension wheel 3 has completed its rotation, the pressing and locking member 6 is pressed toward the side of the tension wheel 3, so that one end of the pressing and locking member 6 presses the side of the tension wheel 3 to limit the rotation of the tension wheel 3, thereby fixing the linear position of the tension sleeve 2. At the same time, the meshing structure between the outer tooth portion 31 and the clamping portion 21 ensures that after the tension wheel 3 is fixed, the positions of the clamping portion 21 and the tension sleeve 2 are also fixed, thereby maintaining the tension state of the cable 1.

[0039] Further, such as Figure 4As shown, the tensioning bracket includes a first side plate 100 and a second side plate 200, and the first side plate 100 and the second side plate 200 are respectively arranged on both sides of the tensioning wheel 3, and locking threaded holes are arranged on the side surfaces of the first side plate 100 and the second side plate 200 corresponding to the tensioning wheel 3, and a compression locking member 6 is installed in the locking threaded hole in threaded cooperation.

[0041] The other parts of this embodiment are the same as those of Embodiment 1, and thus will not be described in detail.

When the tension wheel 3 rotates, the outer gear ring 311 can be driven to rotate, and the meshing structure between the outer gear ring 311 and the linear rack 211 can drive the linear rack 211 to move linearly, and finally drive the tension sleeve 2 to linearly tension the cable 1.

[0045] The other parts of this embodiment are the same as those of Embodiment 1 or 2, and thus will not be described in detail.

[0046] Embodiment 4:

[0047] A cable stabilizing tensioning device, improved on the basis of any one of embodiments 1-3, such as Figure 4 As shown, a clamping bracket is provided on the top of the tensioning sleeve 2, and a clamping wheel 4 is rotatably provided at one end of the clamping bracket close to the cable 1, and a fixing portion 5 is provided at one end of the clamping bracket away from the cable 1.

[0048] By sliding the axle of the clamping wheel 4 along the vertical slide groove, the distance between the clamping wheel 4 and the tensioning wheel 3 can be adjusted to ensure that the rim of the clamping wheel 4 can clamp the sliding part 22 at the top of the tensioning sleeve 2 to ensure the stability of the tensioning sleeve 2 during subsequent linear movement.

[0049] Further, such as Figure 1 and Figure 2 As shown, a slide seat 8 is slidably arranged in the vertical slide groove, and a connecting hole is arranged on the slide seat 8, which is rotatably connected to the end of the wheel shaft of the clamping wheel 4; a locking threaded hole is arranged on the slide seat 8 corresponding to the third side plate 300 or the fourth side plate 400, and a locking bolt 7 is threadedly installed in the locking threaded hole.

[0050] A bearing is provided in the connection hole, and the end of the wheel shaft of the clamping wheel 4 is rotatably connected with the inner hole of the bearing. The slide seat 8 is slid along the vertical slide groove, thereby driving the clamping wheel 4 to move closer to or away from the tensioning wheel 3, so as to adjust the distance between the clamping wheel 4 and the tensioning wheel 3, and ensure that the clamping wheel 4 can press the tensioning sleeve 2 with appropriate force, so as to avoid excessive clamping force causing the tensioning sleeve 2 to slide and jam, and to avoid too little clamping force causing the tensioning sleeve 2 to become unstable during the sliding process.

[0051] After the position adjustment of the slide seat 8 is completed, the locking bolt 7 can be tightened so that one end of the locking bolt presses against the side wall of the third side plate 300 or the fourth side plate 400 to fix the position of the slide seat 8.

[0055] The cooperation between the groove and the sliding guide block 221 ensures that the tensioning sleeve 2 slides basically along a linear direction, thereby preventing the tensioning sleeve 2 from shaking in a large range, thereby ensuring the stability of the tensioning sleeve 2 during the linear movement process.

[0056] The other parts of this embodiment are the same as any one of Embodiments 1-4, so they are not described again.
