Description

Technical Field

[0001] The present invention belongs to the technical field of gearboxes, and specifically relates to a gearbox for a winch device used in the construction of a distribution network. Background Art

[0002] The construction of a distribution network refers to the process of building, installing, commissioning, and maintaining a distribution network system. During the construction of a distribution network, a winch device is required. The winch device can quickly and accurately complete tasks such as the traction, tightening, and fixing of wires and cables. Compared with traditional manual operations, it can greatly improve the construction efficiency. During the use of the winch device, the operating speed of the winch device can be changed through a gearbox to meet different construction requirements.

[0003] The patent with the publication number CN220488244U discloses a gearbox for a new type of winch, including a mounting plate and a lubricating oil tank. The top of the mounting plate is fixedly installed with a housing. A driving shaft is rotatably connected inside the housing. A transmission shaft is rotatably connected above the driving shaft inside the housing. A first main gear is sleeved on the driving shaft. A secondary gear is sleeved on the driving shaft on the right side of the first main gear. The top of the secondary gear is meshed with a transmission gear. The right end of the transmission gear is fixedly installed with a transmission rod. The transmission rod is rotatably connected to the inner wall of the housing. A second main gear is arranged on the transmission shaft. A bearing is fixedly installed inside the inner ring of the second main gear. This gearbox for the new type of winch can achieve the speed change function without replacing the connected output shaft, saving the time for changing the output shaft for speed change adjustment, thereby further improving the work efficiency. At the same time, it can split and drip the lubricating oil onto multiple gears, making the lubricating oil on the gears more uniform, thereby ensuring the lubrication effect.

[0004] However, the above technical solution still has the following deficiencies in the actual application process: The speed change purpose is achieved by changing the meshing ratio of the gears. And in order to avoid the phenomenon of gear passivation due to wear, a lubrication mechanism is set up to lubricate the gears. However, due to the large number of gears, multiple branch pipes are set up to align with the gears, and the lubricating oil is dripped onto multiple gears through the branch pipes for lubrication. Usually, in the case of adapting to different working loads and optimizing the equipment performance, etc., the gears inside the gearbox may be replaced with gears of different sizes. When the branch pipes are in fixed positions, it is difficult to adapt to gears of different sizes, and it may occur that the lubricating oil does not accurately drip on the gears. And when the lubricating oil drips onto the gears, if the gears are in a rotating state, the lubricating oil may be thrown off, resulting in insufficient lubrication and affecting the lubrication effect.

[0022] Please refer to Figures 1 - 8 , the present invention provides a technical solution: a gearbox for a winch device used in the construction of a distribution network, including a box body 1. One side of the box body 1 penetrates and rotatably arranges a transmission shaft 5. Both sides of the transmission shaft 5 are sleeved and fixedly connected with a first gear 6 and a second gear 9. The first gear 6 and the second gear 9 are both located inside the box body 1. One side of the bottom of the inner cavity of the box body 1 is slidably connected with an adjustment seat 7.

[0029] One side of the lifting plate 20 is fixedly connected with a third sliding rod 35. The third sliding rod 35 is slidably connected with a guide plate 36. A plurality of sliding grooves are arranged on the guide plate 36, and a guide post 37 is inserted into the sliding grooves on the guide plate 36 and is slidably connected therewith.

[0030] One side of the guide plate 36 is threadedly connected with a third threaded rod 30. The upper end of the third threaded rod 30 is rotatably arranged on the lifting plate 20. One side of the upper end surface of the lifting plate 20 is fixedly connected with a third motor 29, and the output end of the third motor 29 is fixedly connected with one end of the third threaded rod 30.

[0031] A diameter-adaptive anti-splash mechanism is also arranged on the lifting plate 20; The diameter-adaptive splash-proof mechanism includes adjusting rods 28 fixedly connected to both sides of the upper end surface of the lifting plate 20. The lower ends of the two adjusting rods 28 are respectively fixedly connected with a first frame 21 and a second frame 22, and the first frame 21 is inserted and slidably connected with the second frame 22.

[0032] One side of the upper end of the adjusting rod 28 is threadedly connected with a fourth threaded rod 34. Both ends of the fourth threaded rod 34 are rotatably arranged on the lifting plate 20. One side of the upper end surface of the lifting plate 20 is fixedly connected with a fourth motor 33. Both output ends of the fourth motor 33 are fixedly connected with one end of the fourth threaded rod 34.

[0033] Specifically, in the prior art, the purpose of speed change is achieved by changing the meshing ratio of gears. And, in order to avoid the phenomenon of gear passivation due to wear, a lubrication mechanism is provided to lubricate the gears. However, due to the large number of gears, multiple branch pipes are provided to align with the gears, and the lubricating oil is dripped onto the multiple gears through the branch pipes for lubrication. Usually, the gears inside the gearbox may be replaced with different sizes of gears when adapting to different working loads and optimizing the equipment performance. When the branch pipes are in fixed positions, it is difficult to adapt to different sizes of gears, and the lubricating oil may not be accurately dripped onto the gears. Moreover, when the lubricating oil drips onto the gears, if the gears are in a rotating state, the lubricating oil may be thrown off, resulting in insufficient lubrication and affecting the lubrication effect. Therefore, to solve the above problems, when this embodiment is in use, for the convenience of subsequent description, Gear 1 6, Gear 2 9, Gear 3 13, and Gear 4 14 are collectively referred to as gears to be lubricated. When lubrication work needs to be carried out, according to the positions of the gears to be lubricated, the motor five 40 drives the lead screw one 2 to rotate, the motor one 4 drives the lead screw two 15 to rotate, and the electric push rod two 18 drives the lifting plate 20 to descend. In this way, the position of the lifting plate 20 in the XYZ axis directions can be adjusted until the lubricating pipe 27 is close to the upper part of the gear to be lubricated. At this time, according to the diameter of the gear to be lubricated, the motor three 29 drives the lead screw three 30 to rotate, causing the guide plate 36 to move up and down. Since the chute in the middle of the guide plate 36 is vertical, the guide post 37 in the middle will not move due to the movement of the guide plate 36. However, the chutes of the guide plate 36 are chutes with different slopes. Therefore, the guide posts 37 except for the middle one will move horizontally due to the up and down movement of the guide plate 36. The slider 38 slides on the fixed rod 39, causing the distances between multiple lubricating pipes 27 to change equally, and the distance between the two end lubricating pipes 27 does not exceed the diameter of the gear to be lubricated. At this time, multiple lubricating pipes 27 are evenly distributed above the gear to be lubricated. At the same time, according to the distance between the two end lubricating pipes 27, the motor four 33 drives the lead screws four 34 on both sides to rotate, causing the two adjusting rods 28 to slide simultaneously in different directions. The frame one 21 and the frame two 22 slide relative to each other until the rectangular encirclement formed by the frame one 21 and the frame two 22 can cover the area above the gear to be lubricated, and the frame one 21 and the frame two 22 are as close as possible to the gear to be lubricated without contacting the gear to be lubricated. Then, the pump body 24 is used to pump out the lubricating oil in the lubricating oil tank 23, and the lubricating oil then drips onto the gear to be lubricated through the hose one 25, the long pipe 26, the hose two 32, and the lubricating pipe 27. Since multiple lubricating pipes 27 are evenly distributed above the gear to be lubricated, the lubricating oil also evenly drips on the surface of the gear to be lubricated, improving the lubrication effect. At the same time, the lubricating oil thrown off by the gear to be lubricated will be intercepted by the frame one 21 and the frame two 22, and then drip onto the gear to be lubricated from the inner surfaces of the frame one 21 and the frame two 22, thus avoiding the situation where when the lubricating oil drips on the gear, due to the gear being in a rotating state, the lubricating oil is thrown off, resulting in insufficient lubrication and affecting the lubrication effect. Then, by repeating the above operations, the gears to be lubricated at various positions inside the box body 1 can be lubricated, and the orientations of the lubricating pipe 27, the frame one 21, and the frame two 22 can be adjusted according to the sizes of the gears to be lubricated to adapt to gears of different sizes. Even if the gears inside the box body 1 are replaced, the lubrication effect of each gear can be ensured.

[0034] Working principle: The box body 1 is installed on the winch equipment through the positioning pin 11, and the transmission shaft 5 is connected to the winding and unwinding assembly of the winch equipment. The driving shaft 12 is driven to rotate by the second motor 10, so that the third gear 13 and the fourth gear 14 can rotate synchronously. When the second gear 9 meshes with the third gear 13, since the diameter of the third gear 13 is smaller than that of the second gear 9, the third gear 13 drives the second gear 9 to rotate slowly. When the adjusting seat 7 is driven to slide at the bottom of the inner cavity of the box body 1 by the first electric push rod 8, the third gear 13 can be disengaged from the second gear 9, and the fourth gear 14 meshes with the first gear 6, and the fourth gear 14 drives the first gear 6 to rotate. Since the diameter of the first gear 6 is smaller than that of the fourth gear 14, the fourth gear 14 drives the first gear 6 to rotate quickly, thus achieving the purpose of changing the speed of the transmission shaft 5, and the rotation speed of the transmission shaft 5 can be adjusted according to the actual needs of the winch equipment, and then different usage requirements can be adapted. When lubrication work needs to be carried out, according to the position of the gear to be lubricated, the first threaded rod 2 is driven to rotate by the fifth motor 40, the second threaded rod 15 is driven to rotate by the first motor 4, and the second electric push rod 18 drives the lifting plate 20 to descend, so that the position of the lifting plate 20 in the XYZ axis directions can be adjusted in the above way until the lubricating pipe 27 is close to the upper part of the gear to be lubricated. At this time, according to the diameter of the gear to be lubricated, the third threaded rod 30 is driven to rotate by the third motor 29 to move the guide plate 36 up and down. Since the chute in the middle of the guide plate 36 is vertical, the guide post 37 in the middle will not move due to the movement of the guide plate 36. And the chutes of the guide plate 36 are chutes with different slopes, so the guide posts 37 except the middle one will move horizontally due to the up and down movement of the guide plate 36. The slider 38 slides on the fixed rod 39, so that the distances between multiple lubricating pipes 27 change equally, and the distance between the two end lubricating pipes 27 does not exceed the diameter of the gear to be lubricated. At this time, multiple lubricating pipes 27 are evenly distributed above the gear to be lubricated. At the same time, according to the distance between the two end lubricating pipes 27, the two side fourth threaded rods 34 are driven to rotate by the fourth motor 33, so that the two adjusting rods 28 slide in different directions at the same time, and the first frame 21 and the second frame 22 slide relatively until the rectangular encirclement formed by the first frame 21 and the second frame 22 can cover the area above the gear to be lubricated, and the first frame 21 and the second frame 22 are as close as possible to the gear to be lubricated without contacting the gear to be lubricated. Then, the lubricating oil in the lubricating oil tank 23 is pumped out by the pump body 24, and the lubricating oil drops onto the gear to be lubricated through the first hose 25, the long pipe 26, the second hose 32 and the lubricating pipe 27. Since multiple lubricating pipes 27 are evenly distributed above the gear to be lubricated, the lubricating oil also drops evenly on the surface of the gear to be lubricated, improving the lubrication effect. At the same time, the lubricating oil thrown off by the gear to be lubricated will be intercepted by the first frame 21 and the second frame 22, and then drops onto the gear to be lubricated from the inner surfaces of the first frame 21 and the second frame 22, thus avoiding the situation that when the lubricating oil drops on the gear, due to the rotation of the gear, the lubricating oil is thrown off, resulting in insufficient lubrication and affecting the lubrication effect. Then, repeat the above operations.It can lubricate the gears to be lubricated at various positions inside the box body 1, and can adjust the orientations of the lubricating pipe 27, the first frame 21, and the second frame 22 according to the sizes of the gears to be lubricated to adapt to gears of different sizes. Even if the gears inside the box body 1 are replaced, the lubrication effect on each gear can be ensured.
