Description

Technical Field

[0001] This utility model relates to the field of cable guiding technology, and in particular to a cable guiding device for port loading and unloading equipment. Background Technology

[0002] As external power supply equipment, the cable mounting scheme design for port machinery directly affects the power supply reliability of the equipment and is a key aspect of port machinery design. Port cranes, as core electric loading and unloading machinery, have become essential equipment in terminal operation areas due to their versatility, high efficiency, and ease of operation. Since cranes rely on external cables for power, control, and communication, the reliability of the cable fixing method directly affects the normal operation of the equipment; therefore, optimizing the guidance and protection of the mounting cables is crucial.

[0003] Existing cable guiding methods for port cranes generally employ a steel wire mesh sheath design, where high-strength steel wire is woven into a flexible mesh to completely encase the cable. The other end of the wire mesh sheath is mechanically connected to the rigid base of the dock power supply box via a standard shackle assembly. This traditional fixing method, through the constraint of the steel wire mesh sheath, protects critical connection points such as cable joints and terminal blocks from direct damage by external mechanical impacts, vibrations, and accidental pulling forces, thereby ensuring the physical reliability of the power supply connection to a certain extent.

[0004] However, this traditional fixing method has obvious functional defects: its design only focuses on the static fixing and protection of the cable, completely lacking the function of flexible guidance during cable operation. In actual working conditions, due to the lack of an effective guiding mechanism, the cable will be subjected to complex multi-directional stress during equipment operation, and the resulting damage will directly shorten the service life of the cable. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies that lack flexible guidance functions, and to propose a cable guiding device for port loading and unloading equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a cable guiding device for port loading and unloading equipment, including a sleeve, a connecting shell fixedly installed at the end of the sleeve, an arc groove opened on the outer surface of the connecting shell, a dual-axis motor fixedly installed inside the connecting shell, a connecting shaft fixedly connected to both ends of the dual-axis motor, the central axis of the connecting shaft coincides with the central axis of the arc groove, the end of the connecting shaft extends to the outside of the connecting shell and is fixedly connected to a connecting rod, and a guide wheel is rotatably installed at the end of the connecting rod.

[0008] Preferably, a support seat is rotatably fitted on the outer side of the sleeve, and the lower end of the support seat is fixedly installed on the surface of the fixed platform.

[0010] Preferably, a pressing mechanism is also fixedly installed inside the connecting shell, and a fan plate is fixedly installed on the outside of the connecting shaft, with the pressing mechanism located inside the fan plate.

[0011] Preferably, the extrusion mechanism includes a box body, which is fixedly installed inside the connecting shell. An electric telescopic rod is fixedly installed inside the box body, and a push plate is fixedly installed at the end of the electric telescopic rod. Pressure rods are slidably provided through both sides of the box body. One end of the pressure rod extends into the box body and is fixedly installed with a linkage plate. A spring is sleeved on the outer side of the end of the pressure rod.

[0012] Preferably, the length direction of the electric telescopic rod is perpendicular to the length direction of the pressure rod.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1: Refer to Figure 1-3 A cable guiding device for port loading and unloading equipment includes a sleeve 3, with a connecting shell 4 fixedly installed at the end of the sleeve 3. The sleeve 3 and the connecting shell 4 are fixed to external mechanical equipment. The installation method is relatively flexible, and those skilled in the art can directly implement it according to specific needs without creative labor, so it will not be described in detail here. An arc groove 5 is formed on the outer surface of the connecting shell 4. A dual-axis motor 6 is fixedly installed inside the connecting shell 4. The two ends of the dual-axis motor 6 are fixedly connected to the connecting shafts 7. When the dual-axis motor 6 is started, it can drive the connecting shafts 7 at both ends to rotate synchronously. The dual-axis motor 6 is equipped with a self-locking structure to keep the connecting shafts 7 stable when the machine stops. The central axis of the connecting shaft 7 coincides with the central axis of the arc groove 5, and its end extends to the outside of the connecting shell 4 and is fixedly connected to the connecting rod 16. A guide wheel 17 is rotatably installed at the end of the connecting rod 16. The gap between the arc groove 5 and the guide wheel 17 is designed to precisely meet the cable accommodation requirements.

[0022] When the connecting shaft 7 rotates, its rotational torque is transmitted to the guide wheel 17 through the connecting rod 16, driving the guide wheel 17 to rotate synchronously. This linkage mechanism can precisely adjust the circumferential position of the guide wheel 17, thereby achieving continuous control of the cable laying angle. As shown in the attached figure, when the guide wheel 17 rotates to a specific phase, its groove center plane forms a precise 90° spatial angle with the cable inlet / outlet axis. At this time, the system can guide the cable to complete a standard right-angle turn. This mechanical angle adjustment mechanism not only ensures that the cable bending radius meets the specifications, but also effectively avoids excessive twisting or stress concentration of the cable during the turning process.

[0023] A first flexible ring 18 is fixedly installed on the end edge of the sleeve 3, and a second flexible ring 19 is fixedly installed on the end edge of the connecting shell 4 located below the arc groove 5. Both flexible rings are made of sponge material. The first flexible ring 18 effectively protects against contact wear between the cable and the end of the sleeve 3, while the second flexible ring 19 protects the contact interface between the cable and the end edge of the connecting shell 4. This design effectively avoids direct mechanical friction between the cable and the edge of the device through a flexible buffer structure, thereby significantly reducing the risk of cable sheath damage.

[0024] Working Principle: In operation, the cable guiding device of this port loading and unloading equipment first inserts the cable into the sleeve 3, then exits through the guide gap between the arc groove 5 on the outer side of the connecting shell 4 and the guide wheel 17. The dual-axis motor 6 is activated, driving the connecting rod 16 to rotate the guide wheel 17, dynamically adjusting it to different angles to adapt to the diverse bending requirements of the cable and providing stable flexible support. Compared to the traditional integral sleeve guiding method, this device uses a composite guiding design utilizing the arc groove 5 and the guide wheel 17, significantly reducing the contact area between the cable and the guiding mechanism, effectively reducing frictional resistance. This structure not only optimizes the cable bending path but also reduces cable sheath wear caused by sliding friction, extending cable service life, while improving the flexibility and reliability of the guiding process.

[0025] Example 2: In Example 1, the sleeve 3 and the connecting shell 4 are generally fixed and their positions cannot be changed. Therefore, only the guiding angle of the cable can be adjusted, not the guiding direction, which lacks flexibility. Therefore, this example is proposed. (Refer to...) Figure 1-3 As another preferred embodiment of this utility model, based on embodiment 1, a support seat 2 is rotatably sleeved on the outer side of the sleeve 3, and the lower end of the support seat 2 is fixedly installed on the surface of the fixed platform 1. The sleeve 3 can rotate inside the support seat 2, thereby rotating the overall angle of the connecting shell 4 and the guide wheel 17, and adjusting the guiding direction of the cable as needed, making it more flexible.

[0026] A friction ring 20 is fixedly installed on the inner surface of the support base 2. The friction ring 20 is sleeved on the outer side of the sleeve 3. The surface of the friction ring 20 in contact with the sleeve 3 is uniformly provided with rubber anti-slip protrusions, which can keep the sleeve 3 stable in the normal state and facilitate the rotation of the sleeve 3 when needed. Of course, other fixing methods can also be used, such as using bolts to fix the rotated sleeve 3 to the support base 2.

[0027] Example 3: In Example 1, although the dual-axis motor 6 is equipped with a self-locking structure to maintain the stability of the guide wheel 17, the self-locking structure inside the dual-axis motor 6 is subjected to stress from the guide wheel 17 over a long period of time, resulting in significant wear and affecting its service life. Therefore, this example is proposed. (Refer to...) Figure 2-3 As another preferred embodiment of this utility model, based on embodiment 1 or embodiment 2, a pressing mechanism is also fixedly installed inside the connecting shell 4, a fan plate 8 is fixedly installed on the outside of the connecting shaft 7, the pressing mechanism is located inside the fan plate 8, and an anti-slip pad 9 is fixedly installed on the surface of the fan plate 8 near the pressure rod 14. The end of the pressing mechanism contacts the anti-slip pad 9, which can fix the position of the fan plate 8 and play a locking role, which can reduce the pressure on the self-locking structure inside the dual-axis motor 6.

[0028] The extrusion mechanism includes a box body 10, which is fixedly installed inside the connecting shell 4. An electric telescopic rod 11 is fixedly installed inside the box body 10. The length direction of the electric telescopic rod 11 is perpendicular to the length direction of the pressure rod 14. A push plate 12 is fixedly installed at the end of the electric telescopic rod 11. The electric telescopic rod 11 can drive the push plate 12 to move. Pressure rods 14 are slidably provided through both sides of the box body 10. One end of the pressure rod 14 extends into the box body 10 and is fixedly installed with a linkage plate 13. A spring 15 is sleeved on the outer side of this end of the pressure rod 14. When the push plate 12 moves, it pushes the linkage plate 13 away from each other, and the spring 15 is compressed, thereby driving the pressure rod 14 to extrude the anti-slip pad 9. This can position and limit the position of the fan plate 8, so that the angle of the guide wheel 17 will not change.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
