Description

Technical Field

[0001] The invention relates to the technical field of cable guides, in particular to a cable pulley guide device with adjustable tension. Background Art

[0002] Cables are the bridge that carries electricity from the power generation end to the power consumption end. In urban power grids, underground cables and overhead cables build a transmission network to ensure the power supply to thousands of households, commercial places, public facilities, hospitals, schools, etc. With the rapid development of the power industry, power cables, as the key medium for transmitting electric energy, their installation quality and operating status directly affect the stability and safety of the entire power system. During the installation process of power cables, in order to ensure the normal operation of the cables and extend their service life, it is particularly important to perform appropriate tensioning adjustments. Cables can be divided into transmission cables, distribution cables, control cables, etc. according to their use. The tensioning requirements of each type of cable are also different, so the demand for tensioning devices is different. From urban power grid construction to complex underground operations, from factory automation to cross-sea communications, they can all play a role. They are the basic guarantee for the stable and efficient operation of cable systems, and promote the standardization and safety of cable applications in various industries.

[0003] The construction principle of the cable pulley is the same as the definition of a pulley in physics. The cable is guided by rolling the pulley, reducing the friction during laying and avoiding damage to the cable due to pulling. It is suitable for scenarios such as pipe laying, overhead and underground pipelines, making laying smoother. By adjusting the force application point, more physical strength and time can be saved. There are many types of cable pulleys, so users should choose the appropriate one according to the actual working conditions to ensure smooth installation. Cable pulleys play a very important role in the cable installation process, saving manpower, improving work efficiency, speeding up the installation of cables, and reducing the risk of scratching the insulation protective layer due to mopping or turning corners during cable laying, which affects the insulation of the cable and brings convenience to power workers.

[0004] However, the existing devices have the following problems:

[0005] When workers use the cable pulley guide device to adjust the tension of the cable, most devices require manual knobs or tools to adjust, which relies on the operator's experience and is prone to uneven tension or overload problems. The workers' manual screw adjustment requires repeated testing, which is time-consuming and labor-intensive. The fixed guide wheel can only limit the direction of the cable and cannot apply tension, resulting in manual tightening when winding the cable, which is inefficient and poses a safety risk, further reducing the overall practicality of the cable pulley guide device. Summary of the Invention

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figures 1 to 8 The present invention provides a cable pulley guide device with adjustable tension. This cable pulley guide device with adjustable tension is used in scenarios where cables are installed and guided. In this embodiment, the structure of the cable pulley guide device is improved to facilitate workers to adjust the tension of the cable more conveniently. Specifically, in order to facilitate workers to adjust the tension of the cable, as a preferred solution in this embodiment, the cable pulley guide device is specifically a cable pulley guide device with adjustable tension, which can adjust the tension of the cable.

[0034] See also Figures 1 to 8 The present invention provides a technical solution: a cable pulley guide device with adjustable tension, which is mainly used in scenarios of installing and guiding cables.

[0035] It comprises a first side plate 1 and a second side plate 8, wherein:

[0036] A positioning plate 2 is fixedly installed on the side of the upper end of the first side plate 1, and a rotating shaft 3 is clamped on the side of the positioning plate 2. A threaded rod 4 is sleeved on the outer surface of the rotating shaft 3, and a pulley 5 for storage is threadedly connected to the outer surface of the threaded rod 4. A mounting block 6 is clamped on one end of the rotating shaft 3, and a servo motor 7 is fixedly installed on one side of the mounting block 6.

[0037] In this embodiment, a stable frame structure is formed by setting the first side plate 1, the second side plate 8 and the positioning plate 2, which integrates the servo motor 7, the rotating shaft 3, the threaded rod 4 and the pulley 5 into one. The overall structure is compact and occupies a small space. It can be applied to the guidance and tension adjustment scenes of various cables of different specifications, has good adaptability to complex working environments, and further enhances the application range and practicality of the device. At the same time, the setting of the mounting block 6 can facilitate the staff to fix the servo motor 7 more stably on the side of the second side plate 8, further ensuring the stability of the servo motor 7 when working. The arrangement of the threaded rod 4, pulley 5, mounting block 6 and servo motor 7, by turning on the servo motor 7, can drive the rotating shaft 3 to rotate, and drive the threaded rod 4 to rotate, so that the pulley 5 can be automatically displaced and adjusted along the threaded rod 4, which can effectively avoid the problem of uneven tension or overload caused by improper manual operation, significantly improve the accuracy and stability of the adjustment, and solve the problem that traditional manual screw adjustment requires staff to repeatedly test to achieve the appropriate cable tension, which is time-consuming and labor-intensive, further improving the overall practicality of the cable pulley guide device, wherein the model of the servo motor 7 is YE3-80M1-4.

[0038] The side of the first side panel 1 is fixedly connected with a reinforcement plate 21 for connection, and one side of the reinforcement plate 21 is fixedly connected to the side of the second side panel 8. Through the setting of the reinforcement plate 21, the staff fixes the reinforcement plate 21 between the first side panel 1 and the second side panel 8 to form a stable frame, which makes it easier for the staff to install and assemble other components, ensuring that the device as a whole will not shake, thereby further enhancing the overall stability.

[0039] The side of the second side panel 8 is fixedly connected with a positioning ring 9, and the interior of the positioning ring 9 is clamped with a reinforcing rod 10. Through the setting of the positioning ring 9 and the reinforcing rod 10, the staff fixes the reinforcing rod 10 between the first side panel 1 and the second side panel 8, and cooperates with the reinforcing plate 21, which can further strengthen the rigidity of the first side panel 1 and the second side panel 8, thereby ensuring that the staff is more convenient when installing other components.

[0040] The side of the first side panel 1 is fixedly connected with a clamping block 11 for connection, and the upper end of the clamping block 11 is inserted with a bolt 12 for fixing. Through the arrangement of the clamping block 11 and the bolt 12, it is convenient for the staff to fix the first side panel 1 and the second side panel 8 more firmly to the upper end of the bottom plate 13, further ensuring the stability of the first side panel 1 and the second side panel 8, and preventing the first side panel 1 and the second side panel 8 from shaking when the staff installs other components on the first side panel 1 and the second side panel 8.

[0041] A base plate 13 for support is fixedly installed at the lower end of the first side panel 1, and a positioning pin 14 for fixing is inserted at the upper end of the base panel 13. Through the setting of the base panel 13 and the positioning pin 14, the first side panel 1 and the second side panel 8 are placed vertically on the preset installation position of the base panel 13, and the first side panel 1 and the second side panel 8 can be fixed by the block 11 and the bolt 12, and the base panel 13 can be fixed by the setting of the positioning pin 14.

[0042] A threaded head 15 for fixing is inserted into the side of the positioning plate 2. The threaded head 15 passes through the side of the positioning plate 2 and is threadedly connected to the side of the first side plate 1. Through the setting of the threaded head 15, the positioning plate 2 can be more firmly fixed to the side of the first side plate 1, which can play a positioning role for the rotating shaft 3, further ensuring that the rotating shaft 3 will not be displaced when rotating, thereby ensuring the stability of the rotating shaft 3.

[0043] A mounting plate 16 for positioning is fixedly mounted on the side of the outer surface of the first side panel 1, and a snap ring 17 for positioning is fixedly connected to the side of the mounting plate 16. By setting the mounting plate 16 and the snap ring 17, and by cooperating with the snap ring 17 and the positioning plate 2, the rotating shaft 3 stuck between the first side panel 1 and the second side panel 8 can be limited, further ensuring that when the servo motor 7 is started and the rotating shaft 3 is driven to rotate, there is no shaking of the rotating shaft 3 during rotation.

[0044] A screw 18 for fixing is inserted into the side of the mounting plate 16. The screw 18 passes through the side of the mounting plate 16 and is threadedly connected to the upper end of the outer surface of the first side plate 1. Through the arrangement of the mounting plate 16 and the screw 18, it is convenient for the staff to fix the mounting plate 16 and the retaining ring 17 more firmly to the side of the first side plate 1, further ensuring the stability of the retaining ring 17 when limiting the rotating shaft 3.

[0045] The outer surface of the threaded rod 4 is threadedly connected with a limit block 19 for positioning. The side of the limit block 19 is clamped on the side of the pulley 5. Through the setting of the limit block 19, the internal thread of the limit block 19 is adapted to the threaded rod 4. After being screwed in, it rests on both sides of the pulley 5, which can limit the axial displacement range of the pulley 5 and prevent the pulley 5 from shaking on the threaded rod 4, further ensuring the stability of the pulley 5 on the threaded rod 4.

[0046] A positioning pin 20 is inserted on the other side of the mounting block 6. The pin 20 passes through the other side of the mounting block 6 and is threadedly connected to the side of the second side plate 8. The provision of the pin 20 makes it easier for the staff to fix the mounting block 6 more firmly on the side of the second side plate 8, thereby facilitating the staff to install the servo motor 7, thereby ensuring that the servo motor 7 does not shake during operation, ensuring the stability of the servo motor 7 during operation, and further improving the overall stability of the cable pulley guide device.

[0047] The electrical components mentioned in this article are all electrically connected to an external main controller, and the main controller can be a conventional known device for controlling a computer or the like.

[0048] In summary, when the cable pulley guide device with adjustable tension is used:

[0049] 1. First, move the assembled and debugged device to the application scene. By matching the positioning pins 14 of the bottom plate 13 with the prefabricated installation holes on site, and using the clamping blocks 11 and bolts 12, the staff can more firmly fix the first side plate 1 and the second side plate 8 to the upper end of the bottom plate 13. Manually rotate the pulley 5 so that it is near the middle position of the threaded rod 4 as the initial adjustment reference position, and check the servo motor 7 to ensure that the motor's forward and reverse rotation and speed adjustment functions are normal;

[0050] 2. Secondly, at the corresponding position of the second side plate 8, the mounting block 6 is installed through the pin 20. The pin 20 passes through the prefabricated holes of the mounting block 6 and the second side plate 8. After tightening, the mounting block 6 is rigidly connected to the second side plate 8, which can fix the mounting block 6. Then, the servo motor 7 is fixed to one side of the mounting block 6, and the output shaft of the servo motor 7 is clamped with one end of the rotating shaft 3 to ensure power transmission. By starting the servo motor 7, the rotating shaft 3 can be driven to rotate, and the threaded rod 4 can be driven to rotate and the pulley 5 at the upper end of the threaded rod 4 can be driven to rotate. Check the connection strength of each component to ensure that there is no looseness or interference, and complete the overall assembly of the device.

[0051] 3. Then, the cable to be guided and tensioned is passed along the direction of the pulley 5 groove to ensure that the cable is in good contact with the pulley 5 and there is no risk of the cable falling out of the groove. If the tension is too low, the control system sends a forward rotation command to the servo motor 7. The motor drives the shaft 3 to rotate, which drives the threaded rod 4 to rotate, causing the pulley 5 to move away from the cable fixed end along the threaded rod 4. The tension is continuously adjusted until it returns to the preset range. If the tension is too high, the control system sends a reverse rotation command, and the pulley 5 moves towards the cable fixed end, reducing the cable wrap angle and tension until it returns to the normal range.

[0052] 4. Finally, observe the operating status of the device and check the wear of the pulley 5 groove. If the wear exceeds the threshold, replace the pulley 5 in time. You can judge the tightness of the connecting parts such as the threaded head 15, the pin 20, and the bolt 12 by measuring the groove depth and surface roughness. Clean the dust and debris on and around the pulley 5 to prevent it from affecting the transmission and tension detection. Maintain the servo motor 7 according to the equipment maintenance cycle. At the same time, check the thread wear of the threaded rod 4. If there is slippage or deformation, replace the threaded rod 4 and the matching pulley 5 in time to ensure the adjustment accuracy and device reliability.
