Description

Technical Field

[0001] This utility model belongs to the technical field of cable conveying auxiliary equipment, and specifically relates to a cable turning mechanism. Background Technology

[0002] During the cable production or transmission process, long-distance transmission is often required, and sometimes the transmission direction of the cable needs to be adjusted to ensure smooth transmission.

[0003] Chinese patent CN215666343U discloses a cable turning guide wheel device, including a mounting plate; a support frame disposed at the bottom of the mounting plate for supporting the mounting plate; a guide wheel assembly rotatably disposed on the mounting plate, around which the cable is wound; and a guide roller assembly disposed on the mounting plate, the guide roller assembly including two sets of guide rollers, each set including two parallel and spaced guide rollers, through which the cable passes; the guide roller assembly includes two sets, arranged circumferentially around the guide wheel assembly; wherein the cable enters from one set of guide rollers, passes through the guide wheel assembly, and exits from the other set of guide rollers. This technical solution achieves safe and reliable cable turning transmission.

[0004] The guide wheel assembly in this prior art rotates in a planar manner, so the cable being transported is also transported in a planar manner, meaning that the two ends of the cable are at similar heights. However, this method is not suitable for wind towers, where there is a large difference in the height of the cable on both sides. Using this method to transport cables can easily cause jamming, affecting the smoothness of cable transport, or the cable surface may come into contact with (rub against) the edges and corners during transmission, causing wear on the cable surface. Utility Model Content

[0005] The purpose of this utility model is to provide a cable turning mechanism, thereby overcoming the problems of uneven transmission and cable wear during the transmission process caused by a large height difference between the two ends. The specific technical solution is as follows:

[0006] A cable turning mechanism, comprising:

[0007] The mounting base is fixed to the mounting point by bolts;

[0008] The mounting bracket is mounted on the mounting base;

[0009] A multi-directional hanger, which is mounted on the mounting bracket;

[0010] Guide pulleys are hung in any direction of the multi-directional bracket;

[0011] A universal anchor, which is detachably mounted on the mounting base;

[0012] A steering structure is rotatably mounted on the top of the multi-directional hanger. One end of the cable is fixed to a universal anchor, passes around the steering structure, and is wound up to the lifting device. The other end is led out from the lifting device, passes around the guide pulley, and is connected to the object being lifted. The steering structure can rotate around the top of the multi-directional hanger according to the sway of the cable winding direction during the lifting device's cable winding process. The guide pulley can rotate or swing around the mounting point according to the sway of the object being lifted during the lifting process.

[0013] Preferably, the mounting bracket includes a frustum-shaped bracket composed of several vertical mounting rods, reinforcing ribs, connecting crossbars, and stabilizing rods, and the universal anchor is fixedly installed inside the mounting bracket.

[0014] Preferably, the multi-directional bracket includes several hanging holes facing different directions.

[0015] Preferably, the device has four hanging holes that are perpendicular to each other.

[0016] Preferably, the guide pulley includes a suspension hook, a mounting body, and a load-bearing pulley. The mounting body is hung on the hanging hole via the suspension hook, and the load-bearing pulley is rotatably mounted on the mounting body.

[0017] Preferably, the steering structure includes a rotating sleeve, a mounting plate frame, a rotating shaft, and a steering pulley. The rotating sleeve is rotatably inserted into the multi-directional bracket, the mounting plate frame is mounted on the rotating sleeve, the rotating shaft is mounted on the mounting plate frame, the steering pulley is rotatably mounted on the rotating shaft, and the cable passes around the steering pulley and through the rotating sleeve and is bolted to the universal anchor.

[0018] Preferably, the contact surfaces of the load-bearing pulley and the steering pulley with the cable are provided with a rubber layer.

The turning structure and guide pulley in the cable turning mechanism can be adjusted in position according to the needs of the cable output direction to ensure smooth cable transmission. At the same time, the rotation plane of the guide pulley is perpendicular to the horizontal plane, so that the cable turning mechanism can be used to transport cables with large height differences at the two ends of the transmission.

[0032] Example

[0033] like Figures 1 to 3 As shown, a cable turning mechanism specifically includes a mounting base 100 fixedly installed at a designated erection point by bolts. A mounting bracket 200 is mounted on the mounting base 100. The top of the mounting bracket 200 is provided with a multi-directional hanger 300 having multiple orientations towards the hanging point. A guide pulley 400 is hung in any direction of the multi-directional hanger 300. A turning structure 500 is rotatably mounted on the top of the multi-directional hanger 300. When using this cable turning mechanism, one end of the cable is fixed to a universal anchor 600, then passes around the turning structure 500 and is wound onto a lifting device. The other end of the cable wound onto the lifting device is led out from the lifting device, passes around the guide pulley 400, and is connected to the object to be lifted. During hoisting and transportation, there is a significant height difference between the object to be hoisted and the hoisting equipment. The object is lifted by reeling in the cable using the hoisting equipment. The position of the guide pulley 400 and the orientation of the output cable from the steering structure 500 can be adjusted to match the reeling in the hoisting equipment, ensuring smooth cable transmission. It is worth noting that, for stability during hoisting (cable transmission), the mounting base 100, mounting bracket 200, multi-directional hanger 300, and steering structure 500 are made of alloy steel.

[0034] Preferably, the mounting bracket 200 includes several vertical mounting rods 210, reinforcing ribs 220, connecting crossbars 230, and stabilizing rods 240. The four vertical mounting rods 210 are respectively vertically installed at the four corners of the mounting base 100. The reinforcing ribs 220 are connected to two adjacent vertical mounting rods 210. The connecting crossbars 230 are connected to two adjacent vertical mounting rods 210. One end of each of the four stabilizing rods 240 is connected to the top of the vertical mounting rod 210, and the other end converges at the multi-directional hanger 300. Similarly, the reinforcing ribs 220 or the connecting crossbars 230 are also provided between two adjacent stabilizing rods 240. The four vertical mounting rods 210 and the four stabilizing rods 240 form a frustum-shaped bracket. The universal anchor 600 is fixedly installed inside the mounting bracket 200. It is worth mentioning that the vertical mounting rod 210, reinforcing rib 220, connecting crossbar 230 and stabilizing rod 240 are actually steel bars. The vertical mounting rod 210, reinforcing rib 220, connecting crossbar 230 and stabilizing rod 240 are welded together end to end to form the mounting bracket 200.

[0035] Furthermore, the diameter of the universal anchor 600 is larger than the diameter of the multi-directional bracket 300. Therefore, the universal anchor 600 can be disposed within the mounting bracket 200 (since the diameter of the universal anchor 600 is larger than the diameter of the multi-directional bracket 300, the universal anchor 600 cannot be detached from the mounting bracket 200). If the universal anchor 600 is disposed within the mounting bracket 200, a placement hole needs to be provided through the mounting base 100. During installation, the universal anchor 600 is first fixedly installed at the designated mounting point, and then the cable turning mechanism is placed over the universal anchor 600 through the placement hole so that the universal anchor 600 is located within the mounting bracket 200. One end of the cable is then attached to the universal anchor 600.

[0036] Furthermore, the universal anchor 600 can also be directly fixedly installed on the mounting base 100.

[0037] In some preferred embodiments, the multi-directional bracket 300 includes four hanging holes 310 with mutually perpendicular orientations, oriented east, south, west, and north, respectively. It is worth noting that, depending on requirements, the multi-directional bracket 300 can also be provided with hanging holes 310 in more orientations. This design only exemplifies a design with four orientations.

[0038] In some preferred embodiments, the guide pulley 400 includes a suspension hook 410, a mounting body 420, and a load-bearing pulley 430. The mounting body 420 is hung on the hanging hole 310 via the suspension hook 410, and the load-bearing pulley 430 is rotatably mounted on the mounting body 420.

[0039] In some preferred embodiments, the steering structure 500 includes a rotating sleeve 510, a mounting plate 520, a rotating shaft 530, and a steering pulley 540. A central through hole for mounting the rotating sleeve 510 is provided at the center of the multi-directional bracket 300. The rotating sleeve 510 is rotatably inserted into the central through hole and can rotate accordingly to changes in cable output. The mounting plate 520 is mounted on the rotating sleeve 510, the rotating shaft 530 is mounted on the mounting plate 520, and the steering pulley 540 is rotatably mounted on the rotating shaft 530. The cable passes around the steering pulley 540 and through the rotating sleeve 510, and is secured to the universal anchor. Notably, a rubber layer is provided on the contact surfaces of the load-bearing pulley 430 and the steering pulley 540 with the cable. This rubber layer ensures that the cable surface will not be worn due to contact during transmission, thus preventing damage and extending the cable's lifespan.

[0040] Next, the working principle of this embodiment will be described in detail so that those skilled in the art can better understand this utility model:

[0041] The universal anchor 600 is fixedly installed at the designated erection site. The cable turning mechanism is covered on the universal anchor 600, and the mounting base 100 is fixedly installed at the designated erection site by bolts. The guide pulley 400 is hung on the hanging hole 310 of the multi-directional bracket 300 in a certain direction (this hanging is determined according to the required output position and is not arbitrary). When using the cable turning mechanism, one end of the cable is fixed to the universal anchor 600, then passes around the turning structure 500 and is wound up to the lifting device. The other end of the cable wound up to the lifting device is led out from the lifting device, passes around the guide pulley 400, and is connected to the object to be lifted. During the hoisting and transportation process, there is a significant height difference between the object to be hoisted and the hoisting equipment. The object is hoisted by winding the cable using the hoisting equipment. Since the object is easily affected by wind during the hoisting process, it may sway, causing the cable used to hoist the object to wobble during winding. When the object sways, it will pull the guide pulley 400 to swing or rotate around the hanging point (the connection point where the guide pulley 400 is hung on the multi-directional bracket 300). Therefore, the swinging or rotating of the guide pulley 400 is used to balance the changes in the direction and angle of cable transportation during the hoisting process, thereby improving the smoothness of cable winding, i.e., the smoothness of transportation. Furthermore, the position of the guide pulley 400 and the orientation of the output cable of the steering structure 500 can be adjusted to adapt to the winding of the hoisting equipment, ensuring the smooth transmission of the cable.

[0042] In summary, this utility model provides a cable turning mechanism. The turning structure and guide pulley in the cable turning mechanism can be adjusted in position according to the requirements of the cable output direction to ensure smooth cable transmission. At the same time, the rotation plane of the guide pulley is perpendicular to the horizontal plane, so that the cable turning mechanism can be used to transport cables with large height differences at the two ends of the transmission.

These descriptions are not intended to limit the present invention to the precise forms disclosed, and it is obvious that many changes and variations can be made based on the above teachings. Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention.
