Description

Technical Field

[0001] The present application relates to the technical field of cable transportation, and in particular to a stabilizing device for high-altitude cables. Background Art

[0002] When high-altitude operations involve power assistance, it is necessary to stretch the cables on the ground to the high-altitude operations, such as cranes. The bridge of the crane is located high in the air, and the power equipment on the bridge is powered by cables to the ground. Due to the height of the bridge itself, the cables are relatively heavy. In order to prevent the cables from fluttering in the air due to the influence of wind, fixing devices are often used to fix the cables to the metal frame of the crane, which can reduce the degree of shaking and reduce the tension on the cables caused by the weight of the cables.

[0003] One side of the existing fixing device is hung on the metal frame, and a telescopic sleeve is set on the other side. The change of the aperture of the telescopic sleeve is achieved by changing the tightness of the bolts. The cable is passed vertically through the telescopic sleeve, and the cable is fixed in the telescopic sleeve by tightening the bolts. When the cable needs to rise or fall, the fixing device is removed from the metal frame and moved with the cable. When it reaches a specific height, the fixing device is put on the metal frame again.

[0004] However, the fixing device moves with the cable, which not only increases the weight of the cable, but also makes it easy for the fixing device to get stuck on the metal frame, thus affecting the flexibility of the cable.

[0005] Therefore, there is an urgent need for a stabilizing device for aerial cables to solve the above technical problems. Utility Model Content

[0006] In order to solve the above technical problems, the present application provides a stabilizing device for aerial cables, which can improve the flexibility of the cables when rising or falling.

[0011] The self-locking area is provided with a through hole, the through hole is aligned with the gap between the two eccentric wheels, the cable passes through the through hole and the gap, the cable contacts the two eccentric wheels respectively, and the size of the gap is controlled by the steering of the two eccentric wheels.

[0012] Optionally, a transmission area is formed on the other side of the partition, and two transmission gears are arranged in the transmission area. The two transmission gears are in contact side by side, and the two transmission gears are respectively connected to the two eccentric wheels.

[0013] Optionally, a locking structure is provided in the transmission area, and an end of the locking structure is buckled on the transmission gear, thereby limiting the rotation of the transmission gear.

[0014] Optionally, the locking structure includes a locking rod and a spring, one end of the locking rod is movably connected to the transmission area via a rotating shaft, and the other end is buckled on the transmission gear. The locking rod can rotate around the rotating shaft, and the spring is arranged above the locking rod, and both ends of the spring respectively abut against the upper surface of the locking rod and the inner wall of the transmission area.

[0015] Optionally, a movable limit plate is provided on one side of the transmission area, the limit plate abuts against the lower surface of the locking rod, a pull ring is provided outside the self-locking sleeve, the pull ring passes through the self-locking sleeve and is connected to the limit plate, and the pull ring is controlled to vertically move the limit plate.

[0016] Optionally, a limit block is provided on the transmission gear, the limit block is fixed in the tooth gap of the transmission gear, and the limit block is used to limit the rotation angle of the two transmission gears.

[0017] Optionally, a plurality of connection grooves are provided on the fixing sleeve, and the baffles on the fixing sleeve are embedded in the connection grooves, and the distance between each connection groove and the self-locking sleeve is different.

When the cable rises, the gap increases, and the two eccentric wheels do not restrict the cable, so that the cable can move upward freely. When the cable has a tendency to move downward, the gap decreases, and the two eccentric wheels squeeze the cable against each other, thereby clamping the cable. Therefore, the present application can achieve the effect of free upward movement of the cable and restricted downward movement, thereby improving the flexibility of the cable.

[0022] Secondly, the application does not move with the cable and does not add weight to the cable;

[0023] In addition, when the cable needs to be lowered, the gap between the two eccentric wheels can be manually increased so that the eccentric wheels do not restrict the cable, thereby allowing the cable to drop freely. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] The present application provides a stabilizing device for an aerial cable, which is used to improve the flexibility of the cable in ascending and descending. The specific implementation process of the present application is described as follows.

[0039] See also Figures 1 to 8 , the present application provides a stabilizing device for an aerial cable, comprising:

[0040] A fixed sleeve 1, a self-locking sleeve 2 and an eccentric wheel 3; the self-locking sleeve 2 is connected to the fixed sleeve 1, and the fixed sleeve 1 is used to be connected to the bracket 10; a partition 21 is provided on the self-locking sleeve 2, and a self-locking area 22 is formed on one side of the partition 21, and two eccentric wheels 3 are arranged side by side in the self-locking area 22; a perforation is provided on the self-locking area 22, and the perforation is aligned with the gap between the two eccentric wheels 3, and the cable 9 passes through the perforation and the gap, and the cable 9 contacts the two eccentric wheels 3 respectively, and the size of the gap is controlled by the steering of the two eccentric wheels 3.

[0041] The fixing sleeve 1 is arranged in an "n" shape and can be buckled directly from top to bottom on the high-altitude bracket 10. Different sizes of fixing sleeves 1 can be arranged to adapt to brackets 10 of different sizes. To prevent the fixing sleeve 1 from moving randomly on the bracket 10, the lower end of the fixing sleeve 1 can be connected by a long bolt, so that the fixing sleeve 1 is fixed to the bracket 10, and the bracket 10 can be clamped by tightening the long bolt.

[0042] The self-locking sleeve 2 is connected to one side of the fixed sleeve 1. The self-locking sleeve 2 and the fixed sleeve 1 can be integrally formed, or can be detachably connected by bolts, screws or snaps. In this application, there is no specific limitation on the connection method between the two, which is subject to what is actually achievable.

[0043] Please continue reading Figure 1 , the lower part of the self-locking sleeve 2 is a hollow area, in which a partition 21 is arranged, and the partition 21 divides the hollow area into a self-locking area 22 and a transmission area 23, and two eccentric wheels 3 are arranged side by side in the self-locking area 22, and there is a gap between the two eccentric wheels 3, and the size of the gap changes with the rotation of the two eccentric wheels 3; when the eccentric wheels 3 rotate, the outer wheel of the eccentric wheel 3 rotates normally, and the inner part of the eccentric wheel 3 rotates eccentrically, and the two eccentric wheels 3 rotate relatively at the same time; the structure of the eccentric wheel 3 is as shown in Figure 7 and Figure 8 shown.

[0044] For example, when the cable 9 rises, both sides of the cable 9 contact with the inside of the two eccentric wheels 3, so that the left eccentric wheel 3 rotates counterclockwise and the right eccentric wheel 3 rotates clockwise. During the rotation, the gap between the two eccentric wheels 3 increases accordingly. When the gap increases to the point where the eccentric wheels 3 do not exert pressure on the cable 9, the cable 9 rises freely and the eccentric wheels 3 do not rotate accordingly. When the cable 9 descends, during the descent, both sides of the cable 9 contact with the inside of the two eccentric wheels 3, so that the left eccentric wheel 3 rotates clockwise and the right eccentric wheel 3 rotates counterclockwise. During the rotation, the gap between the two eccentric wheels 3 decreases accordingly, and the pressure of squeezing the cable 9 gradually increases until the cable 9 is completely stuck. After being stuck, the cable 9 no longer descends.

[0045] Two transmission gears 4 are arranged side by side in the transmission area 23. The transmission gears 4 are parallel to the eccentric wheel 3. The center of the transmission gear 4 is connected to the center of the eccentric wheel 3. One transmission gear 4 is connected to one eccentric wheel 3, and the two are synchronously rotated. The two transmission gears 4 are meshed with each other. By controlling the rotation of one transmission gear 4, the rotation of the other transmission gear 4 can be realized. That is, by setting the meshing transmission gears 4, the synchronous rotation of the two eccentric wheels 3 can be ensured, so that the two eccentric wheels 3 can clamp the cable 9 at the same time or release the cable 9 at the same time.

[0046] Optionally, in one practicable manner, a locking structure 5 is provided in the transmission region 23, and an end of the locking structure 5 is buckled on the transmission gear 4, thereby limiting the rotation of the transmission gear 4. For details, please refer to Figure 5 and Figure 6 The locking structure 5 is arranged beside a transmission gear 4. The locking structure 5 is divided into a locking state and an unlocking state. In the locking state (see Figure 5 The locking structure 5 is buckled on the transmission gear 4, and the locking structure 5 is used to limit the counterclockwise rotation of the left transmission gear 4, or to limit the clockwise rotation of the right transmission gear 4. That is, the locking structure 5 is set to prevent the eccentric wheels 3 on both sides from rotating all the time when the cable 9 rises. Figure 6 As shown), the locking structure 5 is separated from the transmission gear 4. When the cable 9 descends, the locking structure 5 does not restrict the rotation of the transmission gear 4.

[0047] Optionally, in this achievable manner, the locking structure 5 includes a locking rod 51 and a spring 52. One end of the locking rod 51 is movably connected to the transmission area 23 through the rotating shaft 8, and the other end is buckled on the transmission gear 4. The locking rod 51 can rotate around the rotating shaft 8. The spring 52 is arranged above the locking rod 51, and the two ends of the spring 52 are respectively abutted against the upper surface of the locking rod 51 and the inner wall of the transmission rod area. Specifically, the spring 52 is arranged vertically, with the lower end abutting against the upper surface of the locking rod 51 and the upper end abutting against the upper inner wall of the transmission area 23. The spring 52 is located at the end of the locking rod 51 away from the rotating shaft 8, and is used to provide downward pressure to the locking rod 51, so that the locking rod 51 is always buckled on the transmission gear 4;

[0048] The end of the lock rod 51 away from the rotating shaft 8 is set as an arc structure, through which the transmission gear 4 can achieve unidirectional rotation. For example, the lock rod 51 is set on the right transmission gear 4. When it is buckled on the transmission gear 4, the right transmission gear 4 can only rotate counterclockwise and cannot rotate clockwise. When the right transmission gear 4 needs to rotate clockwise to increase the gap between the two eccentric wheels 3, the lock rod 51 can be lifted up to achieve the clockwise rotation of the right transmission gear 4.

[0049] Optionally, a movable limit plate 6 is provided on one side of the transmission area 23, the limit plate 6 abuts against the lower surface of the locking rod 51, a pull ring 7 is provided outside the self-locking sleeve 2, the pull ring 7 penetrates the self-locking sleeve 2 and is connected to the limit plate 6, the pull ring 7 is controlled to vertically move the limit plate 6, the limit plate 6 is movable, and can move up and down in the transmission area 23, when the limit plate 6 is controlled to rise by the pull ring 7, the locking rod 51 is lifted. The limit plate 6 is used to limit the rotation angle of the locking rod 51.

[0050] In addition, in another feasible manner, the limiting plate 6 is fixed, and the pull ring 7 is directly connected to the locking rod 51 , and the movement of the locking rod 51 is controlled by controlling the pull ring 7 to move up and down.

[0051] Optional, please continue to Figure 5 and Figure 6 , a limit block 41 is provided on the transmission gear 4, and the limit block 41 is fixed in the tooth opening of the transmission gear 4, and the limit block 41 is used to limit the rotation angle of the two transmission gears 4. In order to prevent the two eccentric wheels 3 from rotating along with the cable 9 when the cable 9 rises, a limit block 41 is provided on the tooth opening of the transmission gear 4 to prevent the gap between the two eccentric wheels 3 from becoming smaller during the rise of the cable 9, and does not affect the rise of the cable 9. The limit block 41 can be provided on the left transmission gear 4, and can also be provided on the right transmission gear 4.

[0052] Optional, please continue to Figure 4 A plurality of connecting grooves 11 are provided on the fixing sleeve 1, and a baffle 12 on the fixing sleeve 1 is embedded in the connecting groove 11. The distance between each connecting groove 11 and the self-locking sleeve 2 is different. Specifically, the baffle 12 is detachably connected. The baffle 12 can be embedded in different connecting grooves 11 according to needs to change the size of the fixing sleeve 1, so as to adapt to brackets 10 of different sizes, so as to facilitate firmly fixing the fixing sleeve 1 on brackets 10 of different specifications.

[0053] Optionally, vertical perforations are respectively provided on both sides of the baffle 12, and correspondingly, corresponding perforations are also provided on the side of the fixing sleeve 1 close to the self-locking sleeve 2. In actual use, after the fixing sleeve 1 is buckled on the bracket 10, it is fixed by passing long bolts through the perforations, thereby preventing the fixing sleeve 1 from moving randomly.

[0054] In the present application, two eccentric wheels 3 are arranged side by side, and the cable 9 is passed through the gap between the two eccentric wheels 3. When the cable 9 rises, the gap increases, and when the cable 9 falls, the gap decreases, thereby limiting the free fall of the cable 9 and allowing the cable 9 to achieve the effect of free rise.

[0055] Secondly, two transmission gears 4 are provided to connect with the two eccentric wheels 3, so that the two eccentric wheels 3 can rotate synchronously through the transmission gears 4;

[0056] In addition, a self-locking structure is provided on the transmission gear 4 to limit the rotation of the transmission gear 4, thereby preventing the two eccentric wheels 3 from continuously rotating as the cable 9 rises.

[0057] It should be noted that the above description of the disclosed embodiments enables professionals and technicians in the field to implement or use the present application. Various modifications to these embodiments will be apparent to professionals and technicians in the field, and the general principles defined herein can be implemented in other embodiments without departing from the scope of the present application.
