Description

Technical Field

[0001] This utility model relates to the field of cable trough cleaning technology, and in particular to a cable trough cleaning device for container terminal yards. Background Technology

[0002] In the operation of container terminal yards, the maintenance of cable trenches is crucial. Due to the complex terminal environment, after construction is completed, various construction wastes often remain in the cable trenches, such as cement debris, sand and gravel particles, metal scraps, and dust. These accumulations not only affect the normal laying of cables but also cause damage to the cable sheaths, leading to safety hazards and affecting the power supply and equipment operation of the entire terminal. To ensure the efficient and safe operation of the terminal, the need for the research and development of a targeted cable trench cleaning device for container terminal yards has emerged.

[0003] In existing technologies, most equipment for cleaning cable troughs employs relatively simple mechanical structures. Commonly, it involves manually pushing a brush-equipped cleaning tool, moving the brush back and forth within the cable trough to remove debris. The underlying principle relies primarily on human power and physical friction to sweep away accumulated material. Some semi-automated equipment uses a rotating brush head fixed to a simple frame, driven by a small motor. The operator guides the frame along the cable trough to complete the cleaning.

[0004] However, existing technologies have serious drawbacks. The cleaning rollers of existing devices are extremely cumbersome to install and disassemble. When the cleaning rollers are worn out due to long-term use and need to be replaced, workers often need to use a variety of complex tools and spend a lot of time disassembling a series of interconnected parts in order to remove the cleaning rollers. This not only wastes manpower and time, but also greatly reduces the maintenance efficiency of the equipment, thus affecting the continuity of cable trough cleaning work. Therefore, a cable trough cleaning device for container terminal yards is proposed to solve the above problems. Utility Model Content

Multiple wheels are rotatably connected to the bottom of the support chassis, and a dust collection bin is slidably connected inside the support chassis.

[0015] As a further description of the above technical solution:

[0016] The positioning component includes multiple guide wheels, and a support platform is provided between the guide wheels. The bottom of the support platform is fixedly connected to the top of the support chassis.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 - Figure 3 The present invention provides an embodiment of a container terminal yard cable trough cleaning device, comprising a support chassis 1, which supports a positioning component, a cleaning component, a power component, and other components. The support chassis 1 is equipped with a negative pressure device and provides installation space for a dust collection bin 3. The device is moved by wheels 2 at the bottom. A positioning component is provided on the top of the support chassis 1 to determine the position of the device in the cable trough. A cleaning component is provided on the side wall of the support chassis 1 to perform cleaning operations on the cable trough. A power component is provided on the side wall of the cleaning component.

[0034] The cleaning assembly includes a cleaning roller 10, which is made of metal and covered with wear-resistant bristles. It is used to clean dust and debris from the bottom of the cable trough. A linkage rod 16, also made of metal, is slidably connected inside the cleaning roller 10. This linkage rod controls the connection and separation between the cleaning roller 10 and the connecting shaft 14, facilitating the replacement of the cleaning roller 10. A button 15, made of plastic, is fixedly connected to one side of the linkage rod 16 for manual operation. A return spring 18 is located on the other side of the linkage rod 16, which pushes the linkage rod 16 back to its original position after the button 15 is released. One end of the return spring 18 is fixedly connected to the side wall of the linkage rod 16, and the other end is fixedly connected to the side wall of the button 15. A limit switch is provided on the outer wall of the linkage rod 16. The groove 17, or limiting groove 17, is formed by machining during the manufacturing process of the linkage rod 16. It is used to cooperate with the locking rod 19 to unlock and lock the sweeping roller 10. Multiple locking rods 19 are provided on the outer wall of the linkage rod 16. Each locking rod 19 has a limiting plate 20 fixedly connected to its outer wall to limit the position and compression degree of the limiting spring 21. The locking rods 19 and the limiting plate 20 are circumferentially distributed inside the sweeping roller 10. Each locking rod 19 has a limiting spring 21 sleeved on its outer wall to push the locking rod 19, thus locking and unlocking the sweeping roller 10. One end of the limiting spring 21 is fixedly connected to the bottom of the limiting plate 20, and the other end is fixedly connected to the side wall of the button 15. Bearing plates 7 are provided on both the left and right sides of the sweeping roller 10 to support it. This allows for stable rotation and provides mounting positions for components such as the rotating shaft 13 and connecting shaft 14. The rotating shaft 13 is rotatably connected inside one side of the support plate 7, and the connecting shaft 14 is rotatably connected inside the other side of the support plate 7. The rotating shaft 13 and connecting shaft 14 are made of metal and support both ends of the sweeping roller 10, transmitting power to enable its rotation. The power assembly includes a drive motor 9. A connecting block 8 is fixedly connected to the top of the drive motor 9 for mounting and securing it. The side wall of the connecting block 8 is fixedly connected to the side wall of the support plate 7. The output end of the drive motor 9 is fixedly connected to the side wall of the connecting shaft 14, providing power for the rotation of the connecting shaft 14, thereby driving the sweeping roller 10 to rotate. One end of the sweeping roller 10 is slidably connected to the inner wall of the connecting shaft 14. The other end of the sweeping roller 10 is slidably connected to the inner wall of the rotating shaft 13 to ensure stable rotation of the sweeping roller 10. Hydraulic rods 6 and linkage arms 11 are installed on the top of the two side support plates 7. The hydraulic rods 6 are used to adjust the height of the support plates 7, thereby controlling the contact between the sweeping roller 10 and the bottom of the cable trough. The linkage arms 11 are used to maintain the stability of the support plates 7 and transmit force when the hydraulic rods 6 adjust the height of the support plates 7. A base 5 is installed above the hydraulic rods 6 and linkage arms 11 for mounting the hydraulic rods 6, linkage arms 11, and other components, and connecting these components to the support chassis 1. The tops of the hydraulic rods 6 and linkage arms 11 are fixedly connected to the bottom of the base 5, the side walls of the base 5 are fixedly connected to the side walls of the support chassis 1, and the output end of the hydraulic rod 6 is fixedly connected to the top of one side support plate 7.The bottom of the linkage arm 11 is fixedly connected to the top of the support plate 7 on the other side. A suction pipe 12, made of metal, is fixedly connected to the bottom of the base 5 and is used to suck dust and debris swept by the cleaning roller 10 into the dust collection bin 3. The suction pipe 12 is located on the side of the cleaning roller 10. A data antenna 4 is fixedly connected to the top of the support chassis 1. The data antenna 4 is used to receive and transmit signals and is located on the side of the positioning component. Multiple wheels 2 are rotatably connected to the bottom of the support chassis 1 to support it and allow the device to move within the cable trough. A dust collection bin 3 is slidably connected inside the support chassis 1 to collect dust and debris sucked in by the suction pipe 12 for subsequent processing.

[0035] Specifically, after the device is positioned, the operator sends a control signal through the remote control to start the hydraulic rod 6. Under the pressure of the hydraulic oil, the output end of the hydraulic rod 6 pushes the bearing plate 7 downward. The two ends of the sweeping roller 10 are connected to the rotating shaft 13 and the connecting shaft 14 respectively. The displacement of the bearing plate 7 causes the rotating shaft 13, the connecting shaft 14, and the sweeping roller 10 to move downward as a whole. Then, the operator sends a control signal through the remote control to start the drive motor 9. Its output end drives the connecting shaft 14 to rotate, which in turn drives the sweeping roller 10 to rotate. During the rotation, the bristles on the surface of the sweeping roller 10 contact the bottom of the cable trough, sweeping up dust and debris from the bottom of the cable trough. The suction pipe 12 behind the sweeping roller 10 then starts working. The suction pipe 12 is internally connected to a suction device located inside the support chassis 1. This device generates negative pressure to draw the swept dust and debris into the dust collection chamber 3. When the sweeping roller 10 needs replacement due to severe wear, the operator first locates the support plate 7 at the bottom of the linkage arm 11. Using a wrench, the operator unscrews the screws on the support plate 7 and removes the support plate 7 along with the rotating shaft 13 from one side of the sweeping roller 10. Then, the operator presses the button 15 on one side of the sweeping roller 10. The displacement of the button 15 causes the linkage rod 16 and the limiting groove 17 to move inward. The locking rod 19 was previously squeezed by the outer wall of the linkage rod 16 and was inserted into the connecting shaft 14. When the linkage rod 16 moves towards the center of the sweeping roller 10, the locking rod 19 loses the squeezing of the outer wall of the linkage rod 16. Then, under the reset force of the limiting spring 21 on its outer wall, its top retracts into the sweeping roller 10 and its bottom inserts into the limiting groove 17. At this time, the operator holds the sweeping roller 10 with both hands and uses the connecting shaft 14 as a support point to remove the sweeping roller 10 from the inside of the connecting shaft 14, thus achieving the effect of quick disassembly and assembly of the sweeping roller 10.

[0036] Reference Figure 4The positioning assembly includes multiple guide wheels 28, each consisting of a metal hub and rubber tires. The guide wheels 28 contact the inner walls of the cable trough on both sides, guiding the device along the trough. During positioning, they adhere to the inner walls of the cable trough, limiting the lateral displacement of the device within the trough and ensuring accurate cleaning. A support platform 22 is positioned between the guide wheels 28, providing installation space and support for components such as the second drive motor 23, main rocker arm 24, auxiliary rocker arm 25, sliding block 26, and connecting rod 27. The bottom of the support platform 22 is fixedly connected to the top of the support chassis 1. The second drive motor 23 is fixedly connected to the bottom of the support platform 22. The output end of the second drive motor 23 is fixedly connected to the main rocker arm 24 via a coupling. The main rocker arm 24 rotates under the drive of the second drive motor 23. This drives the secondary rocker arm 25 to move, thereby adjusting the position of the guide wheel 28. The main rocker arm 24 is located inside the support platform 22. Both ends of the main rocker arm 24 are rotatably connected to the secondary rocker arm 25 through a pin connection mechanism. The other ends of the two secondary rocker arms 25 are rotatably connected to the sliding block 26, which is used to transmit the rotational motion of the main rocker arm 24 and convert it into the linear motion of the sliding block 26. The bottom of the sliding block 26 is slidably connected to the bottom of the inner wall of the support platform 22 through a sliding engagement mechanism of the guide rail and the guide groove. The side walls of the sliding block 26 are fixedly connected to left and right symmetrical connecting rods 27. The function of the connecting rods 27 is to transmit the linear motion of the sliding block 26 to the guide wheel 28, drive the guide wheel 28 to move, and make it contact or separate from the inner wall of the cable trough. The outer wall of the connecting rod 27 is slidably connected to the inner side of the support platform 22. One end of the connecting rod 27 is fixedly connected to the side wall of the guide wheel 28.

[0037] Specifically, when using the container terminal cable trough cleaning device, the staff first adjusts the direction of the device according to the condition of the cable trough, then places the device inside the cable trough. At this time, the staff operates the remote control device to start the drive motor 23 at the bottom of the support platform 22. The output end of the drive motor 23 drives the main rocker arm 24 to rotate. Under the drive of the drive motor 23, the main rocker arm 24 rotates in a circle inside the support platform 22, with the axis of the output end of the drive motor 23 as the center. The main rocker arm 24 and the auxiliary rocker arm 25 are rotatably connected by a pin. When the main rocker arm 24 rotates... When arm 24 rotates, it drives the auxiliary rocker arm 25 to rotate around the pin. The rotation of the auxiliary rocker arm 25 causes the sliding block 26 connected to its other end to slide outward under the restriction of the guide strip at the bottom of the support platform 22. The sliding of the sliding block 26 causes the connecting rod 27 on its side wall to slide accordingly, thereby causing the guide wheel 28 to contact the inner walls of the left and right sides of the cable trough. At this time, the guide wheel 28 is in contact with the inner walls of the left and right sides of the cable trough, restricting the lateral displacement of the device in the cable trough, thus completing the positioning of the cleaning device, thereby achieving the effect of ensuring that the cleaning device accurately cleans the cable trough.

[0038] Working principle: When using the cable trough cleaning device in the container terminal yard, the staff first places the device in the cable trough. Then, the staff starts the drive motor 23 via the remote control. The drive motor 23 drives the main rocker arm 24 to rotate, which in turn drives the auxiliary rocker arms 25 at both ends to rotate as well. The rotation of the auxiliary rocker arms 25 causes the sliding block 26 connected to its other end to slide outward under the restriction of the guide strip at the bottom of the support platform 22. The sliding of the sliding block 26 causes the connecting rod 27 on its side wall to slide as well, which in turn causes the guide wheel 28 to contact the inner walls of the left and right sides of the cable trough. This completes the positioning of the cleaning device, thereby ensuring that the cleaning device accurately cleans the cable trough.

[0039] Subsequently, the staff used the remote control device to activate the output end of the hydraulic rod 6 to push the bearing plate 7 downward. The displacement of the bearing plate 7 caused the sweeping roller 10 to contact the bottom of the cable trough. Then, the drive motor 9 drove the connecting shaft 14 to rotate, which in turn drove the sweeping roller 10 to rotate. The sweeping roller 10 contacted the bottom of the cable trough and swept it. The dust suction pipe 12 behind the sweeping roller 10 then sucked the swept dust and debris into the dust collection bin 3 for subsequent processing.

[0040] When the sweeping roller 10 needs to be replaced due to severe wear, the operator first unscrews the bearing plate 7 at the bottom of the linkage arm 11, removes the bearing plate 7 on one side of the sweeping roller 10 along with the rotating shaft 13, and then presses the button 15 on one side of the sweeping roller 10. The displacement of the button 15 causes the linkage rod 16 and the limiting groove 17 to move inward. The displacement of the linkage rod 16 causes the locking rod 19, which was originally squeezed at the bottom and inserted into the connecting shaft 14, to lose its squeezing force. Then, under the reset force of the limiting spring 21 on its outer wall, its top retracts into the sweeping roller 10 and its bottom inserts into the limiting groove 17. At this time, the operator can remove one end of the sweeping roller 10 from inside the connecting shaft 14, thus achieving the effect of quick disassembly and assembly of the sweeping roller 10.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
