Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, and in particular to a rotating anti-hinged rope device. Background Technology

[0002] With the widespread application of suspended work equipment such as high-rise buildings, special equipment, construction platforms, and maintenance scaffolds, wire ropes, as the main load-bearing and force-transmitting components, directly affect the safety and reliability of the equipment due to their operational stability under lifting, swinging, and rotating conditions. In such devices, a synchronous guiding structure for multiple wire ropes is typically required.

[0003] In existing technologies, when a wire rope rotates within a system, it exhibits a significant yaw angle as the rotation angle increases. When the rotation angle is small (e.g., not exceeding 90 degrees), the yaw of the wire rope remains within a controllable range, and the relative positions of the rope grooves do not become significantly misaligned. However, when the rotation angle exceeds a certain range (e.g., exceeding 135 degrees), rope crossings and kinks easily occur between the wire ropes in a multi-rope system. Especially during lifting and lowering, the mutual friction between the wire ropes increases dramatically, causing localized wear, strand breakage, or even complete rope failure, posing a significant safety hazard. Summary of the Invention

[0004] Therefore, this utility model provides a rotating anti-hinged rope device that can achieve ±180-degree rotation of the anti-hinged rope, so that the wire rope maintains a controllable sway angle throughout the entire rotation range, thereby avoiding rope snagging and wear, and improving the overall safety and service life of the system.

[0005] To solve the above-mentioned technical problems, this utility model provides a rotating anti-hinged rope device, comprising: Fixed brackets and rotating brackets; A first rotary mechanism is installed between the fixed bracket and the rotary bracket to allow the rotary bracket to rotate relative to the fixed bracket. The rope inlet pulley assembly is installed on the fixed bracket; A rope outlet pulley assembly is installed on the rotary support; An anti-hinged rope pulley device includes an anti-hinged rope pulley assembly and a second rotation mechanism. The anti-hinged rope pulley assembly is located between the rope inlet pulley assembly and the rope outlet pulley assembly. The anti-hinged rope pulley assembly includes two sets of guide rope pulleys with parallel and adjacent axes. The second rotation mechanism is installed between the anti-hinged rope pulley assembly and the fixed bracket to allow the anti-hinged rope pulley assembly to rotate relative to the fixed bracket. The rope grooves of the rope inlet pulley group, the anti-hinged rope pulley group, and the rope outlet pulley group are aligned one by one, and the center of the rope outlet groove of the rope inlet pulley group in the vertical direction is aligned with the center of the rope inlet groove of the rope outlet pulley group in the vertical direction. The wire rope is introduced through the inlet pulley group, transitioned through the anti-hinged rope pulley group, and then exited through the outlet pulley group. During the rotation of the slewing bracket, the anti-hinged rope pulley group can rotate along with the wire rope due to the action of the wire rope, and its rotation angle is 1 / 2 of the rotation angle of the slewing bracket.

[0006] In one embodiment of this utility model, the first slewing mechanism includes a first slewing bearing and a drive motor. The outer ring of the first slewing bearing is connected to the upper flange of the slewing bracket, and the inner ring of the first slewing bearing is connected to the lower flange of the fixed bracket. The drive motor is mounted on the lower flange of the fixed bracket, and its shaft end gear meshes with the peripheral end gear of the outer ring of the first slewing bearing.

[0007] In one embodiment of this utility model, the drive motor is a geared motor.

[0008] In one embodiment of this utility model, the second slewing mechanism includes a second slewing bearing, and the anti-hinged rope pulley group further includes a pulley frame connected to the two sets of guide rope pulleys. The outer ring of the second slewing bearing is connected to the fixed bracket, and the inner ring of the second slewing bearing is connected to the pulley frame.

[0009] In one embodiment of this utility model, the wire rope passes through the middle position of the rope grooves corresponding to the two sets of guide pulleys.

[0010] In one embodiment of this utility model, the fixing bracket adopts a hollow structure and has an opening located next to the rope inlet pulley group.

[0011] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art: This utility model discloses a rotating anti-hinged rope device. By installing an anti-hinged rope pulley device between the fixed support and the rotating support, the device rotates with the wire rope at half the rotation angle of the rotating support under the force of the wire rope. Within a rotation range of ±180 degrees, the maximum sway angle of the wire rope is always limited to within 90 degrees, avoiding the problem of the wire rope getting tangled and hinged during large-angle rotation, and significantly reducing the risk of friction damage to the wire rope during lifting. The two sets of guide pulleys in the anti-hinged rope pulley device can continuously keep the wire rope in the middle position of the rope groove. Whether rotating in the forward or reverse direction, the wire rope will not jump out of the groove or be squeezed against the pulley sidewall, effectively reducing wear and impact, significantly extending the service life of the wire rope, thereby reducing maintenance frequency and replacement costs.

[0020] Reference Figure 1 , Figure 2 As shown, the present invention provides a rotating anti-hinged rope device, comprising: Fixed bracket 1 and rotating bracket 2; fixed bracket 1 is mounted on the suspension device; The first rotary mechanism 3 is installed between the fixed bracket 1 and the rotary bracket 2, so that the rotary bracket 2 rotates relative to the fixed bracket 1; The rope inlet pulley assembly 4 is installed on the fixed bracket 1; The rope outlet pulley group 5 is installed on the rotary bracket 2; An anti-hinged rope pulley device includes an anti-hinged rope pulley group 6 and a second rotation mechanism 7. The anti-hinged rope pulley group 6 is located between the rope inlet pulley group 4 and the rope outlet pulley group 5. The anti-hinged rope pulley group 6 includes two sets of guide rope pulleys 61 with parallel axes and close proximity. The second rotation mechanism 7 is installed between the anti-hinged rope pulley group 6 and the fixed bracket 1 to make the anti-hinged rope pulley group 6 rotate relative to the fixed bracket 1. The rope grooves of the rope inlet pulley group 4, the anti-hinged rope pulley group 6, and the rope outlet pulley group 5 are aligned one by one, and the center of the rope outlet groove of the rope inlet pulley group 4 in the vertical direction is aligned with the center of the rope inlet groove of the rope outlet pulley group 5 in the vertical direction. The wire rope 8 is introduced by the rope inlet pulley group 4, and after passing through the anti-hinged rope pulley group 6, it is led out by the rope outlet pulley group 5. During the rotation of the slewing bracket 2, the anti-hinged rope pulley group 6 can rotate along with the wire rope 8, and its rotation angle is 1 / 2 of the rotation angle of the slewing bracket 2.

[0021] The rope grooves of the rope inlet pulley block 4, the anti-hinged rope pulley block 6, and the rope outlet pulley block 5 are aligned during installation to ensure that the multiple wire ropes 8 remain parallel and evenly stressed throughout the rotation. The addition of the anti-hinged structure stabilizes the geometric relationship of each rope segment, significantly improves the synchronization of multiple ropes, and avoids the risk of uneven load caused by uneven stress on local wire ropes 8. The wire ropes 8 no longer experience kinking, skipping, or excessive swaying, maintaining a smooth and stable lifting process, reducing downtime for adjustments, and improving operational continuity and efficiency. This makes it suitable for high-rise building exterior wall work platforms, outdoor suspended platforms, and other suspended equipment requiring large-angle rotation.

[0022] In one embodiment, the first slewing mechanism 3 includes a first slewing bearing 31 and a drive motor 32. The outer ring of the first slewing bearing 31 is connected to the upper flange of the slewing bracket 2, and the inner ring of the first slewing bearing 31 is connected to the lower flange of the fixed bracket 1. The drive motor 32 is mounted on the lower flange of the fixed bracket 1, and its shaft end gear meshes with the peripheral end gear 33 of the outer ring of the first slewing bearing 31. The drive motor 32 is a geared motor.

[0023] In one embodiment, the second slewing mechanism 7 includes a second slewing bearing 71, and the anti-hinged rope pulley group 6 further includes a pulley frame 62 connected to the two sets of guide rope pulleys 61. The outer ring of the second slewing bearing 71 is connected to the fixed bracket 1, and the inner ring of the second slewing bearing 71 is connected to the pulley frame 62.

[0024] In one embodiment, the wire rope 8 passes through the middle position of the rope grooves corresponding to the two sets of guide pulleys 61.

[0025] In one embodiment, the fixed bracket 1 has a hollow structure and an opening 11 is provided on the side of the rope inlet pulley group 4.

[0026] During installation, first adjust the entire mechanism to the zero-degree position, so that multiple wire ropes 8 are introduced through the rope inlet, and align the rope grooves of the rope inlet pulley group 4, the anti-hinged rope pulley group 6, and the rope outlet pulley group 5 one by one. At the same time, ensure that the center of the rope outlet groove in the vertical direction of the rope inlet pulley group 4 is consistent with the center of the rope inlet groove in the vertical direction of the rope outlet pulley group 5.

[0027] During operation, the drive motor 32 drives the first slewing mechanism 3, which in turn rotates the slewing bracket 2. As the slewing angle increases, the wire ropes 8 in the rope grooves of each pulley block will form a certain sway angle. If the device is not equipped with anti-hinged rope pulley blocks 6, when the slewing angle exceeds approximately 135 degrees, the wire ropes 8 will become tangled, causing multiple wire ropes 8 to rub against each other during the lifting process, resulting in wear or even breakage of the wire ropes 8, thus creating a safety hazard.

[0028] To avoid the aforementioned problems, an anti-hinged rope pulley device is installed between the fixed support 1 and the rotating support 2. During operation, the rotating support 2 is driven to rotate by a geared motor, while the anti-hinged rope pulley device passively follows the rotation through the force exerted on the wire rope 8, but its rotation angle is only half that of the rotating support 2. Therefore, within the entire ±180-degree rotation range, the deviation angle of the anti-hinged rope pulley device relative to the rope inlet pulley group 4 and the rope outlet pulley group 5 is only half of the total rotation angle, ensuring that the maximum sway angle of the wire rope 8 never exceeds 90 degrees, effectively preventing rope kinking and preventing excessive friction and damage to the wire rope 8 during lifting and lowering.

[0029] In addition, the wire rope 8 is always located in the middle of the two guide pulleys 61 when passing through the anti-hinged rope pulley device. It will not jump out of the guide pulley 61 groove of the anti-hinged rope pulley device, regardless of whether it rotates in the forward or reverse direction, thus ensuring that the wire rope 8 runs smoothly and reliably.

[0030] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
