Description

Technical Field

[0001] The present invention relates to the technical field of reduction transmission devices, in particular to a cable traction reduction transmission device for marine vessels. Background Art

[0002] In the daily operation and maintenance of ships, when the power supply cables, communication cables, control cables, etc. on the ship are aged, damaged and need maintenance and replacement, the cables need to be pulled. At this time, the pulling equipment distributed in multiple key positions of the ship will play a role. Through these equipment, the new cables are pulled to the designated location and laid, or the old cables are pulled out from the installation location for removal. The reduction transmission device plays a key role in the pulling process. It can convert the high-speed rotational motion of the driving source into the low-speed and high-torque output required for cable pulling, meeting the cable's demand for high pulling force during pulling; at the same time, the cable pulling speed is controlled through a stable transmission ratio to avoid the cable being broken due to excessive speed, or affecting the maintenance and replacement efficiency due to excessively slow speed, thereby ensuring that the cable pulling process is smooth, safe and efficient.

[0003] However, due to the complex operating environment of ships and large temperature changes, lubricating oil is easy to solidify at low temperatures, resulting in poor fluidity and inability to lubricate transmission components in time. At high temperatures, it is easy to experience viscosity loss, oxidation and deterioration, which reduces the lubrication effect and aggravates component wear. At the same time, during long-term operation, lubricating oil will produce metal debris due to the wear of transmission components, and its own oxidation will also generate impurities such as colloid. These impurities will enter the meshing gap of precision transmission components such as worm and worm wheel, planetary gear and sun gear with the lubricating oil, aggravate component wear, lead to reduced meshing accuracy and reduced transmission efficiency. When installing the reducer, when the reducer is installed on the mounting base plate inside the traction equipment, it needs to be fixed with multiple bolts, and the internal space of the traction equipment is usually relatively small. During the installation process, it is not easy for the operator to quickly tighten multiple bolts in the narrow space, which makes the installation process time-consuming and reduces the installation efficiency.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1 、 Figure 3 、 Figure 4 、 Figure 7 、 Figure 9 、 Figure 10 and Figure 12 As shown, the cable traction reduction transmission device for marine ships described in the present invention includes a reducer body 1, a transmission structure 2 installed on the reducer body 1, a temperature control structure 3 installed on the reducer body 1, a filtering structure 4 installed on the reducer body 1, and a mounting structure 6 installed on the reducer body 1; the filtering structure 4 includes a filter box 401 installed on the reducer body 1 and a slide frame 402 slidably connected to the filter box 401, a filter screen 403 is fixedly connected to the slide frame 402, a sealing cover 406 is installed on the filter box 401, a connecting rod 407 is fixedly connected to the slide frame 402, a sliding rod 408 is fixedly connected to the connecting rod 407, the sliding rod 408 is slidably connected to the sealing cover 406, an oil drain pipe 404 is installed on the filter box 401, the other end of the oil drain pipe 404 is connected to the reducer body 1, and the sliding rod 408 is driven by the driving structure 5.

[0023] Specifically, such as Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 and Figure 9As shown, the filter box 401 is fixedly connected to a mounting frame 410, and two slides 411 are slidably connected in the mounting frame 410. A stopper 412 is fixedly connected to the slide 411, and a fixing plate 409 is fixedly connected to the sealing cover 406. The stopper 412 is slidably connected to the fixing plate 409. A first screw rod 405 is rotatably connected in the mounting frame 410, and the slide 411 is threadedly connected to the first screw rod 405. When the filter screen 403 needs to be replaced, an inner hexagonal wrench is inserted into the hexagonal groove at the end of the first screw rod 405, and the first screw rod 405 is rotated to make the two slides 411 slide toward each other. The movable stopper 412 is separated from the fixed plate 409. At this time, the adjusting plate 503 is pulled to slide with the guide plate 504. The setting of the guide sleeve 505 ensures that the adjusting plate 503 slides smoothly. At the same time, the adjusting plate 503 compresses the first spring 506 to drive the lifting plate 502 and the lifting block 501 to move, so that they are separated from the top of the sealing cover 406. The sealing cover 406 can be quickly disassembled, and the sliding frame 402 and the filter screen 403 can be taken out through the connecting rod 407 to clean impurities to avoid excessive impurities affecting the filtering effect. The thread directions of the two ends of the first screw rod 405 are opposite. The driving structure 5 includes a lifting block 501 slidably connected to the sliding rod 408 and a fixed connecting rod. The lifting plate 502 is connected to the lifting block 501, and the lifting plate 502 is fixedly connected to the adjusting plate 503, and the adjusting plate 503 is slidably connected to the guide plate 504. The reducer body 1 is fixedly connected to the guide rod 507, and the guide plate 504 is slidably connected to the guide rod 507. The guide plate 504 is rotatably connected to the rotating shaft 509, and the rotating shaft 509 is fixedly connected to the roller 510. The roller 510 is rotatably connected to the driving ring 511, and the driving ring 511 is fixedly connected to the protrusion 512 used in conjunction with the roller 510. When the worm 201 rotates, it drives the driving ring 511 to rotate. When the filter 403 on the sliding frame 402 is moved back and forth in the filter box 401, the filter 403 and the impurities in the lubricating oil are relatively displaced, which effectively prevents the impurities from clogging the filter 403, thereby avoiding the filter 403 from being blocked by the filter 403. The blockage causes obstruction to the circulation of the lubricating oil. A guide sleeve 505 is fixedly connected to the guide plate 504, and the adjusting plate 503 is slidably connected to the guide sleeve 505. A first spring 506 is fixedly connected between the adjusting plate 503 and the guide sleeve 505, and a second spring 508 is fixedly connected between the guide plate 504 and the guide rod 507.

[0024] Specifically, such as Figure 1 、 Figure 5 、 Figure 6 and Figure 10 As shown, the transmission structure 2 includes a worm 201 rotatably connected to the reducer body 1 and a worm wheel 202 rotatably connected to the reducer body 1, the worm 201 is fixedly connected to the drive ring 511, the worm 201 is meshed with the worm wheel 202, a mounting seat 203 is fixedly connected to the worm wheel 202, a sun gear 204 is fixedly connected to the mounting seat 203, a planetary gear 205 is rotatably connected to the mounting seat 203 through a mounting shaft, the planetary gear 205 is meshed with the sun gear 204, an output shaft 206 is installed on the mounting seat 203, an external power source drives the worm 201 to rotate, the meshing of the worm 201 and the worm wheel 202 realizes a first-stage reduction, and as the worm wheel 202 rotates, the mounting seat 2 03 drives the sun gear 204 to rotate synchronously, and the sun gear 204 drives multiple planetary gears 205 to revolve around it and rotate on their own. The engagement of the planetary gears 205 and the gear ring 207 realizes secondary deceleration, and finally the power is transmitted to the traction equipment through the output shaft 206. This two-stage deceleration structure can provide large torque output for marine cable traction and meet the high load requirements during cable laying. At the same time, the multi-point engagement design of the planetary gear 205 disperses the force. When the ship's turbulence causes load fluctuations, it can buffer the impact load, extend the service life of the transmission components, and ensure the smoothness of the cable traction process. The output shaft 206 is rotatably connected to the reducer body 1, and a gear ring 207 is fixedly connected to the reducer body 1. The planetary gears 205 engage with the gear ring 207.

[0025] Specifically, such as Figure 1 、 Figure 2 、 Figure 4 、 Figure 7 and Figure 8As shown, the temperature control structure 3 includes a first connecting pipe 301 fixedly connected to the reducer body 1 and a circulating pump 302 installed on the reducer body 1, the other end of the first connecting pipe 301 is installed at the inlet of the circulating pump 302, and the outlet of the circulating pump 302 is installed with a second connecting pipe 303, a radiator 304 is installed on the reducer body 1, the other end of the second connecting pipe 303 is installed at the inlet of the radiator 304, and the outlet of the radiator 304 is installed with a third connecting pipe 305, the other end of the third connecting pipe 305 is installed on the filter box 401 and connected to the top of the filter 403, a heating coil 306 is installed on the second connecting pipe 303, a temperature detector 307 is installed on the reducer body 1, and a detection head 308 is installed on the temperature detector 307, and the detection head 308 is installed on the reducer body 1. The temperature detector 307 detects the temperature of the reducer body 1. The head 308 continuously monitors the oil temperature in the reducer body 1 and transmits the data to the controller 309. When the oil temperature is higher than the set threshold, the controller 309 starts the circulation pump 302, and the lubricating oil enters the circulation pump 302 through the first connecting pipe 301, and then flows into the radiator 304 through the second connecting pipe 303. The fan on the radiator 304 will operate to dissipate heat efficiently. The cooled lubricating oil flows back to the filter box 401 through the third connecting pipe 305 and re-enters the lubrication system. If the oil temperature is too low, the heating coil 306 automatically starts to preheat the lubricating oil. This structure can ensure that the lubricating oil always maintains an appropriate viscosity in cold seas or tropical high temperature environments, avoids insufficient lubrication caused by poor fluidity at low temperatures, or component wear caused by oil deterioration at high temperatures, and ensures the stable operation of the reducer in complex marine temperature environments. The detection end of the detection head 308 is located in the reducer body 1, and the reducer body 1 is equipped with a controller 309.

[0026] Specifically, such as Figure 4 、 Figure 8 、 Figure 11 and Figure 12As shown, the reducer body 1 is provided with a mounting structure 6, which includes four positioning columns 601 fixedly connected to the reducer body 1 and two fixed blocks 602 slidably connected to the positioning columns 601, and the fixed blocks 602 are rollingly connected with balls 603, and the positioning columns 601 are slidably connected with a driving block 606, and the driving block 606 is provided with an inclined surface, and the balls 603 roll with the inclined surface of the driving block 606, and the driving block 606 is fixedly connected with a connecting block 607, and a connecting plate 608 is fixedly connected between the four connecting blocks 607, and the connecting plate 608 is slidably connected to the reducer body 1, and a second screw rod 609 is rotatably connected to the reducer body 1, and the second screw rod 609 threadably drives the connecting plate 608 to drive the four connecting blocks 607 to slide synchronously, and the connecting block 607 will drive the driving When the movable block 606 moves, the inclined surface on the driving block 606 rolls with the ball 603, thereby pushing the fixed block 602 to slide outward along the positioning column 601. When the fixed block 602 abuts the mounting hole of the base, the reducer body 1 is firmly installed. When the connecting plate 608 moves downward, multiple fixed blocks 602 are simultaneously driven to press against the mounting holes between the substrate to be installed, so that the reducer body 1 can be quickly installed, thereby improving the installation efficiency. The connecting plate 608 is threadedly connected to the second screw rod 609, and a guide block 604 is fixedly connected to the fixed block 602. The guide block 604 is slidably connected to the positioning column 601. When the fixed block 602 slides, it will drive the guide block 604 to move. The setting of the guide block 604 makes the movement of the fixed block 602 more stable. A third spring 605 is fixedly connected between the guide block 604 and the positioning column 601.

[0027] When the present invention is in use, the reducer body 1 is first installed on the base of the traction equipment. During operation, the second screw rod 609 is rotated by a tool, and the second screw rod 609 threadedly drives the connecting plate 608 to drive the four connecting blocks 607 to slide synchronously. The connecting block 607 will drive the driving block 606 to move, and the inclined surface on the driving block 606 rolls with the ball 603, thereby pushing the fixed block 602 to slide outward along the positioning column 601. When the fixed block 602 slides, it will drive the guide block 604 to move. The setting of the guide block 604 makes the movement of the fixed block 602 more stable. At the same time, the guide block 604 will cause the third spring 605 to contract. When the fixed block 602 abuts the mounting hole of the base, the reducer body 1 is firmly installed. When the connecting plate 608 moves downward, multiple fixed blocks 602 are simultaneously driven to press against the mounting holes between the substrate to be installed, so that the reducer body 1 can be quickly installed, thereby improving the installation efficiency. When the ship needs to perform cable pulling operations, an external power source drives the worm 201 to rotate, and the meshing of the worm 201 and the worm wheel 202 realizes a first-stage deceleration. As the worm wheel 202 rotates, the mounting seat 203 drives the sun gear 204 to rotate synchronously, and the sun gear 204 drives multiple planetary gears 205 to revolve around it and rotate on their own. The meshing of the planetary gears 205 and the gear ring 207 realizes a second-stage deceleration, and finally the power is transmitted to the pulling equipment through the output shaft 206. This two-stage deceleration structure can provide large torque output for marine cable pulling and meet the high load requirements during cable laying. At the same time, the multi-point meshing design of the planetary gear 205 disperses the force. When the ship is bumpy and causes load fluctuations, it can buffer the impact load, extend the service life of the transmission components, and ensure the smoothness of the cable pulling process. During the long-term cable pulling operation, the temperature detector 307 continuously monitors the oil temperature in the reducer body 1 through the detection head 308 and transmits the data to the controller 309. When the oil temperature is higher than the set threshold, the controller 309 starts the circulation pump 302, and the lubricating oil enters the circulation pump 302 through the first connecting pipe 301, and then flows into the radiator 304 through the second connecting pipe 303. The fan on the radiator 304 will operate to dissipate heat efficiently. The cooled lubricating oil flows back to the filter box 401 through the third connecting pipe 305, and enters the reducer body 1 from the oil drain pipe 404 on the filter box 401. The filter 403 can effectively filter the lubricating oil and intercept impurities therein to avoid These impurities enter the meshing parts of the precision transmission components such as the worm 201, worm wheel 202, and planetary gear 205 inside the reducer body 1 along with the lubricating oil, thereby reducing the wear of the transmission components by the impurities, preventing transmission jams or failures caused by impurities getting stuck, and maintaining the cleanliness of the lubricating oil, extending the service life of the lubricating oil, and ensuring a stable and long-lasting lubrication effect. If the oil temperature is too low, the heating coil 306 automatically starts to preheat the lubricating oil, ensuring that the lubricating oil always maintains an appropriate viscosity in cold seas or tropical high-temperature environments, avoiding insufficient lubrication caused by poor fluidity at low temperatures, or component wear caused by oil deterioration at high temperatures, thereby ensuring the stable operation of the reducer in complex marine temperature environments; When the worm 201 rotates, it drives the driving ring 511 to rotate. The protrusion 512 on the driving ring 511 rolls and cooperates with the roller 510, so that the roller 510 continuously drives the guide plate 504 to move up and down. The guide plate 504 slides along the guide rod 507. When the guide plate 504 moves, the second spring 508 is continuously deformed, and at the same time, the adjustment plate 503 and the lifting plate 502 are pushed up and down. The lifting plate 502 drives the lifting block 501 and the sliding rod 408 to move up and down, so that the filter 403 on the slide frame 402 performs a reciprocating lifting motion in the filter box 401, so that the filter 403 and the impurities in the lubricating oil are relatively displaced, effectively preventing impurities from clogging the filter 403, thereby avoiding the obstruction of the circulation of the lubricating oil due to the blockage of the filter 403, ensuring that the lubrication system continuously provides clean lubricating oil to each transmission component. To ensure the stable operation of the reducer, the cleaned lubricating oil flows back to the reducer body 1 through the oil drain pipe 404 to ensure the cleanliness of the lubrication system. When the filter 403 needs to be replaced, insert the hexagonal slot at the end of the first screw rod 405 through the hexagonal wrench, rotate the first screw rod 405 to make the two slides 411 slide toward each other, drive the block 412 to disengage from the fixed plate 409, then pull the adjustment plate 503 to make it slide with the guide plate 504. The setting of the guide sleeve 505 ensures that the adjustment plate 503 slides smoothly. At the same time, the adjustment plate 503 compresses the first spring 506 to drive the lifting plate 502 and the lifting block 501 to move, so that it disengages from the top of the sealing cover 406. The sealing cover 406 can be quickly removed, and the sliding frame 402 and the filter 403 can be removed through the connecting rod 407 to clean up impurities to avoid excessive impurities affecting the filtering effect.
