[0021] like Figure 2 and Figure 3 As shown, the steering guide wheel assembly 2 includes a steering mounting seat 2-1 fixedly connected to the hook mounting frame 4, a turntable structure rotatably connected thereto is penetrated in the middle of the steering mounting seat 2-1, and a plurality of steering guide wheels 2-3 arranged in pairs are rotatably connected to the turntable structure, and the pairs of steering guide wheels 2-3 are distributed in a fan shape.

[0022] Among them, the above-mentioned rotating frame structure includes an installation sleeve 2-2, which is inserted into a through hole opened in the middle of the steering mounting seat 2-1 and is rotatably connected to the steering mounting seat 2-1 through a rolling bearing. It also includes two groups of fan-shaped guide wheel plates 2-4 fixed at the ends of the installation sleeve 2-2, and a pair of steering guide wheels 2-3 are rotatably connected between the two groups of fan-shaped guide wheel plates 2-4.

[0024] During operation, as the cable enters or exits the mounting sleeve 2-2, the paired steering guide wheels 2-3 guide the cable, ensuring smooth movement. Since the turret structure is rotatably connected to the steering mounting base 2-1, the turret structure can rotate 360 ​​degrees, allowing the cable to be steered as needed. Both end faces of the steering guide wheels 2-3 abut the corresponding sector-shaped guide wheel plates 2-4, with clearance fit between their inner surfaces.

[0025] See further Figure 2 The above-mentioned anti-slip guide assembly 3 includes two sets of lower anti-slip guide wheels 3-1 and upper anti-slip guide wheels 3-5 distributed in a triangular shape and arranged at the port of the steering mounting seat 2-1. The longitudinal positions of the two sets of lower anti-slip guide wheels 3-1 are adjustable.

[0026] Furthermore, the anti-slip guide assembly 3 also includes a threading plate 3-7 mounted on the steering mounting base 2-1, with a through hole formed in the middle.

The assembly also includes a lower guide wheel seat plate 3-4 disposed below each upper guide wheel seat plate 3-6, with the two sets of lower anti-slip guide wheels 3-1 rotatably connected between the two sets of lower guide wheel seat plates 3-4. The corresponding lower guide wheel seat plates 3-4 and upper guide wheel seat plates 3-6 are connected by a plurality of adjustment screws 3-3, each of which is threaded with a lock nut. To facilitate adjustment of the distance between the corresponding lower guide wheel seat plates 3-4 and upper guide wheel seat plates 3-6, the anti-slip guide assembly 3 also includes an adjustment spring 3-2 sleeved on each adjustment screw 3-3 and located between the lower guide wheel seat plate 3-4 and upper guide wheel seat plate 3-6.

[0027] See further Figure 4 The above-mentioned multi-layer guide wheel assembly 1 includes a multi-layer frame structure installed on the steering mounting seat 2-1, and a plurality of bottom guide wheels 1-2, a plurality of intermediate guide wheels 1-3 and a plurality of top guide wheels 1-4 arranged in pairs and arranged in sequence from bottom to top are rotatably connected in the middle of the multi-layer frame structure.

[0028] The multi-layer frame structure includes two sets of position-limiting mounting plates 1-7 arranged opposite to each other. Each position-limiting mounting plate 1-7 is connected to the steering mounting seat 2-1 via an angle steel installed at the top. A reinforced guide wheel frame 1-5 is fixedly connected to each position-limiting mounting plate 1-7. The two sets of reinforced guide wheel frames 1-5 are arranged opposite to each other and form an inverted T-shaped structure. The upper ends of the two sets of reinforced guide wheel frames 1-5 are fixedly connected to the corresponding position-limiting mounting plates 1-7. The paired bottom guide wheels 1-2 are installed at the lower ends of the reinforced guide wheel frames 1-5. The lower part of each position-limiting mounting plate 1-7 is provided with a notch corresponding to the bottom guide wheel 1-2, thereby facilitating the observation of the threading status.

[0029] In addition, the above-mentioned multi-layer guide wheel assembly 1 also includes two groups of incoming wire guide wheels 1-1 installed at the lower end of the multi-layer frame structure. The two groups of incoming wire guide wheels 1-1 are respectively located on both sides of the bottom guide wheel 1-2 arranged in pairs, and the two groups of incoming wire guide wheels 1-1 are rotatably installed between two groups of limit mounting plates 1-7; a number of incoming and outgoing guide rollers 1-6 arranged in an upper and lower manner are installed at the incoming wire end and the outgoing wire end of the multi-layer frame structure for guiding the cables, and the number of incoming and outgoing guide rollers 1-6 are distributed in an eight-shaped shape.

[0030] In order to prevent the cable from falling off during the guiding process, in this embodiment, the end face of each guide wheel is close to the inner side surface of the corresponding limit mounting plate 1-7 and is clearance-matched therewith.

[0031] The paired intermediate guide wheels 1-3 are rotatably mounted between the two sets of limit mounting plates 1-7, and the paired top guide wheels 1-4 are also rotatably mounted between the two sets of limit mounting plates 1-7; two sets of bottom guide wheels 1-2, intermediate guide wheels 1-3 and top guide wheels 1-4 are each provided.

[0032] In order to improve the practicality of the present invention, at least two groups of multi-layer guide wheel assemblies 1 are provided, and at least two groups of multi-layer guide wheel assemblies 1 are installed in parallel at the bottom of the steering mounting seat 2-1 through plates.

[0033] Working principle:

[0034] In the actual working process, the cable that needs to be turned goes in or out of the anti-slip guide assembly 3, and the cable passes between the two sets of lower anti-slip guide wheels 3-1 located below and the upper anti-slip guide wheel 3-5 located above. Under the limiting and guiding action of the upper anti-slip guide wheel 3-5, the cable can be prevented from shaking up and down due to external force and falling off the lower anti-slip guide wheel 3-1. Since the upper guide wheel seat plate 3-6 and the lower guide wheel seat plate 3-4 are connected by the adjusting screw 3-3, the cable can be prevented from shaking left and right due to external force and falling off the lower anti-slip guide wheel 3-1;

[0035] Since the mounting sleeve 2-2 in the steering guide wheel assembly 2 is rotatably connected to the steering mounting seat 2-1 through a rolling bearing, the turret structure can realize 360-degree rotation, thereby driving the plurality of steering guide wheels 2-3 installed on the turret structure and arranged in pairs in a fan-shaped distribution to realize 360-degree rotation, so that the cable end passing through the turret structure can be rotated 360 degrees in the vertical plane, thereby realizing the steering operation as needed, wherein the plurality of steering guide wheels 2-3 are arranged in pairs, which can also prevent the cable from escaping from the guide wheel, thereby playing a role in preventing the cable from escaping; the steering adjustment operation of a single cable can be realized by the provided steering guide wheel assembly 2;

[0036] When it is necessary to support and guide multiple cables, the multiple cables can be sequentially passed through the multi-layer guide wheel assembly 1 between the paired bottom guide wheels 1-2 and the middle guide wheels 1-3, between the paired top guide wheels 1-4 and the middle guide wheels 1-3, and above the paired top guide wheels 1-4. Each multi-layer guide wheel assembly 1 can achieve the upper and lower distributed guidance of three cables. When more cables need to be supported and guided, the cables can be repeatedly passed through the remaining multi-layer guide wheel assemblies 1, thereby achieving the support and guidance of multiple cables at one time, thereby improving the practicality of the pulley device.
