Description

Technical Field

[0001] The invention relates to the technical field of planetary gear transmission, in particular to a planetary gear transmission device with a gear limiting unhooking structure. Background Art

[0002] Antarctica is a continent covered by ice and snow for a long time, rich in mineral resources. Since the 1760s, countries around the world have competed to explore and survey Antarctica. In 1985, China officially sent a scientific research ship to Antarctica for survey and established the Antarctic Great Wall Station. In 1989, it established the Antarctic Zhongshan Station. Drilling is one of the important methods of Antarctic exploration.

[0003] When drilling in ice, the hardness of different ice layers will be different due to the different freezing times of the ice. In the existing drilling equipment, only the same drilling speed can be maintained, and the personnel cannot timely understand the hardness of the ice layer at the drill bit position. This may cause the drilling rig to overload when encountering a hard ice layer. When encountering a low hardness ice layer, it will cause idle drilling rig power and reduce work efficiency.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are: the working speed can be automatically adjusted.

[0016] (1) By providing various planetary groups and various sun gears, the coordination between different sun gears and their corresponding planetary groups can be adjusted according to the hardness of different ice layers, thereby ensuring that the drill barrel can work normally while maintaining the highest working efficiency.

[0017] (2) By providing the card ball and the card slot, the drill barrel can better drill the high-hardness ice layer, and the drill barrel can automatically stop when it exceeds its workload, preventing the drive motor from being damaged due to long-term overload;

[0018] (3) By providing a hydraulic chamber and injecting hydraulic oil into different positions of the hydraulic chamber, the cooperation between the sliding spline and different sun gears can be adjusted, so as to achieve the purpose of adjusting the output speed. At the same time, since the sliding spline is driven by the sliding magnet, there is no direct contact between the sliding spline and the sliding magnet, so that the possible oil leakage of the sliding spline during movement can be avoided, thereby avoiding the damage of the hydraulic oil to the Antarctic environment.

[0019] (4) By providing a negative pressure chamber and a distribution valve, the hardness of the ice layer being drilled by the drill barrel at this moment can be automatically determined by the matching of each card ball and the card slot in the negative pressure chamber, and the required rotation speed can be automatically adjusted. At the same time, the volume of the hydraulic oil between each valve body and each limit slot can just enable the sliding magnet to move the length of a sun gear, so as to prevent the sliding spline from matching with two sun gears at the same time, causing the sun gears to rotate at the same time but at different rotation speeds and thus get stuck;

[0020] (5) By providing a spiral groove, ice debris will be generated during the drilling process of the drill barrel. These ice debris can enter the gear sleeve through the spiral groove and cool the working gear. They can also lubricate the gears when they are mating, so there is no need to use lubricating oil, which can avoid the pollution of the Antarctic environment caused by lubricating oil leakage;

[0021] (6) By providing a drainage port, a layer of liquid separation membrane can be provided between the inner wall of the drill barrel and the icicle inside it when the drill barrel rotates. This can reduce the friction of the icicle on the inside of the drill barrel and reduce energy waste. After the drilling is completed, the water will refreeze with the inner wall of the drill barrel at a low temperature. At this time, the drill barrel can be taken out to remove the icicle inside for research, without having to cut off the bottom of the icicle through other equipment. This allows scientific expedition team members to carry less tools and reduce the burden on personnel. At the same time, since the frozen water source is the melted water of the icicle itself, it will not affect the subsequent icicle research. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0029] See also Figure 2 , 3The present invention provides a technical solution: a planetary gear transmission device with a gear limit decoupling structure, comprising a power shaft 6, the surface of the power shaft 6 is respectively provided with a sun gear 10, a sun gear 2 11 and a sun gear 3 12, the surface of the sun gear 10 is provided with a planet group 1 7, the surface of the sun gear 2 11 is provided with a planet group 2 8, the surface of the sun gear 3 12 is provided with a planet group 3 9, the diameter of the sun gear 10 is larger than that of the sun gear 2 11, the diameter of the sun gear 2 11 is larger than that of the sun gear 3 12, the planet group 1 7 includes a support plate 1, a support plate 2 One side bearing of plate 1 is connected with a plurality of planetary gears 1, planetary set 2 8 includes support plate 2, one side bearing of support plate 2 is connected with a plurality of planetary gears 2, planetary set 3 9 includes support plate 3, one side bearing of support plate 3 is connected with a plurality of planetary gears 3, planetary gear 1, planetary gear 2 and planetary gear 3 are all matched with gear sleeve 4, support plate 1, support plate 2 and support plate 3 are all fixed structures, when the drilling machine is working, the power shaft provides power for the whole gear set, and the power shaft will only drive one sun gear to rotate, and the rotating sun gear will Drive the corresponding planetary group to rotate, and the planetary group will transmit the rotation to the gear sleeve through the planetary gear inside it, so as to achieve the effect of transmitting power. Due to the different freezing time of the ice layer, the hardness of different ice layers will also be different. When the front end of the drill barrel encounters a hard ice layer, the power shaft can drive the sun gear three to rotate. Since the diameter of the sun gear three is small and the diameter of the planetary gear three in the planetary group three is large, the speed of the power shaft finally transmitted to the gear sleeve will be reduced and the torque will be increased, so that the drill barrel can drill the hard ice layer with low speed and high torque. On the contrary, when the ice layer is soft, the power shaft can drive the sun gear one to rotate. At this time, since the diameter of the sun gear one is large and the diameter of the planetary gear in the planetary group one is small, the speed of the power shaft finally transmitted to the gear sleeve will become larger, so that the work efficiency can be increased when drilling the ice layer with lower hardness. In summary, the cooperation of different sun gears and their corresponding planetary groups can be adjusted according to the hardness of different ice layers, so that the highest work efficiency can be maintained while ensuring the normal operation of the drill barrel;

[0030] See also Figure 1-3 The transmission mechanism includes a transmission sleeve 5, and the ice-breaking mechanism includes a drill barrel 1. The transmission sleeve 5 is located on the surface of the gear sleeve 4. The drill barrel 1 is fixed to one side of the transmission sleeve 5. The bottom of the drill barrel 1 is provided with saw teeth 2. When working, the driving motor drives the power shaft to rotate. The power shaft provides constant power. Then the power shaft drives the planetary gear sets of different diameters to rotate according to the hardness of the ice layer, thereby driving the gear sleeve to rotate at different speeds. During the rotation of the gear sleeve, it drives the transmission sleeve to rotate at the same speed, and the transmission sleeve drives the drill barrel at its end to rotate, so that the drill barrel can drill the ice layer;

[0031] See also Figure 2 ,4 The inner wall of the transmission sleeve 5 is evenly provided with a plurality of slots 17, and a block 27 is arranged between the slots 17. The interior of the gear sleeve 4 is evenly provided with a plurality of negative pressure chambers 28, and a piston 16 is arranged inside the plurality of negative pressure chambers 28. One end of the plurality of pistons 16 is provided with a negative pressure spring 29, and the other end of the plurality of pistons 16 is provided with a card ball 15. The card ball 15 and the slot 17 are a matching structure. In the transmission process of the gear sleeve and the transmission sleeve, the piston is pushed out by the negative pressure spring, and then the piston pushes the card ball out. At this time, the card ball will be stuck in the card groove of the inner wall of the transmission sleeve. When the gear sleeve rotates, the card ball will rotate with the gear sleeve. When the card ball rotates to the block, the card ball will drive the block to rotate together, so as to achieve The gear sleeve drives the transmission shaft to rotate. When the drill barrel encounters a hard ice layer while drilling downward, the resistance encountered by the drill barrel will increase. At this time, the pressure between the card ball and the block will also increase. When the hardness of the ice layer is too high, the resistance encountered by the drill barrel will exceed the elastic force of the negative pressure spring on the card ball. At this time, the card ball will be squeezed into the negative pressure chamber. This is because the gear sleeve cannot drive the transmission sleeve to rotate. This allows the gear sleeve to remain in an idling state until the speed of the gear sleeve decreases. At this time, the gear sleeve can drive the drill barrel to rotate at a low speed and high torque. This not only allows the drill barrel to drill the hard ice layer better, but also can automatically stop after the drill barrel exceeds its workload, preventing the drive motor from being damaged due to long-term overload.

[0032] See also Figure 3 , 4, a hydraulic chamber 25 is arranged inside the power shaft 6, a sliding magnet 26 is arranged inside the hydraulic chamber 25, key slots 13 are arranged in the middle of the sun gear 10, the sun gear 2 11 and the sun gear 3 12, a sliding spline 14 is arranged on the surface of the power shaft 6, the sliding spline 14 and the three sets of key slots 13 are all matching structures, the sliding spline 14 is made of magnetic material, and the sliding spline 14 and the sliding magnet 26 are matching structures. When the drill barrel encounters a hard ice layer, a low speed is required. At this time, the hydraulic oil on the left side of the hydraulic chamber can be discharged through the hydraulic pipe 1, and the hydraulic oil on the right side of the hydraulic chamber will push the sliding magnet to move to the left, and then the sliding magnet will attract the sliding spline on the surface of the power shaft to move to the left, which is the sliding spline will be with the key slot in the middle of the sun gear 3. In this case, the drill barrel will reduce its rotation speed. Similarly, when the drill barrel encounters a low-strength ice layer, the hydraulic oil on the right side of the hydraulic chamber can be discharged through hydraulic pipe 2. At this time, the hydraulic oil will push the sliding magnet to move to the right, and the sliding spline will cooperate with the keyway in the middle of the sun gear 1. This can increase the rotation speed of the drill barrel and improve the overall work efficiency. In summary, by injecting hydraulic oil into different positions of the hydraulic chamber, the cooperation between the sliding spline and different sun gears can be adjusted, so as to achieve the purpose of adjusting the output speed. At the same time, since the sliding spline is driven by the sliding magnet, there is no direct contact between the sliding spline and the sliding magnet, so the possible oil leakage of the sliding spline during movement can be avoided, so as to avoid the damage of the hydraulic oil to the Antarctic environment.

[0033] See also Figure 3 , 4A distribution valve 18 is provided on one side of the transmission sleeve 5. The interior of the distribution valve 18 is divided into a left chamber and a right chamber. A limit groove 1 is provided in the middle of the inner wall of the left chamber and the right chamber, and a limit groove 2 is provided at the bottom of the inner wall of the left chamber and the right chamber. A valve body 19 is provided inside the left chamber, and a valve body 20 is provided inside the right chamber. The valve body 19 and the valve body 20 are respectively matched with the limit groove 1 and the limit groove 2. The valve body 19 and the valve body 20 are both telescopic structures. The bottoms of the valve bodies 19 and 20 are both provided with A supporting spring is arranged, a hydraulic pipe 1 23 is arranged below the left chamber, a hydraulic pipe 24 is arranged below the right chamber, the hydraulic pipe 1 23 is connected to the left pipeline of the hydraulic chamber 25, the hydraulic pipe 24 is connected to the right pipeline of the hydraulic chamber 25, a negative pressure pipe 1 21 is arranged on the top of the valve body 19, a negative pressure pipe 22 is arranged on the top of the valve body 20, the other end of the negative pressure pipe 1 21 is connected to the top pipeline of the negative pressure chamber 28, the other end of the negative pressure pipe 22 is connected to the end pipeline of the negative pressure chamber 28, and the drill barrel encounters a relatively strong When the resistance between the drill bucket and the ice layer is greater than the elastic force of the negative pressure spring, the card ball will be squeezed into the negative pressure chamber. During this process, the card ball will push the piston to move to the bottom of the negative pressure chamber. At this time, the side of the piston inside the negative pressure chamber close to the card ball will generate negative pressure suction on the negative pressure tube 2, and the liquid in the valve body 1 will be absorbed into the negative pressure chamber. When the liquid in the valve body 1 becomes less, it will shorten. At this time, the valve body 1 will move upward under the elastic force of the support spring in the left chamber. During the upward movement, the valve body 1 will exert negative pressure on the lower part of the left chamber. The hydraulic oil on the right side generates suction, so that the hydraulic oil on the left side of the hydraulic chamber enters the left chamber through the hydraulic pipe 1. At this time, the sliding magnet will also be attracted and move to the left. The right side of the hydraulic chamber will suck out the hydraulic oil in the right chamber through the hydraulic pipe 2. Since the hydraulic oil in the right chamber is sucked out, the valve body 2 will drop under the action of negative pressure until it contacts the limit groove 2 at the bottom of its inner wall and stops. In this way, the power shaft can drive the sun gear 3 to rotate. Then, due to the reduction in the rotation speed of the drill barrel, the stuck ball will drive the transmission sleeve to rotate again.

[0034] When the drill barrel encounters an ice layer with a lower hardness, the drill barrel will encounter less resistance. At this time, the elastic force of the negative pressure spring supports the card ball to extend out and get stuck in the card slot. At this time, the side of the piston inside the negative pressure chamber close to the negative pressure spring will generate negative pressure suction on the negative pressure tube 1, causing the fluid in the valve body 2 to decrease. At this time, the valve body 2 will move upward under the action of the support spring, so that the power shaft can drive the sun gear on the right to rotate, thereby increasing the rotation speed of the drill barrel and improving work efficiency. At the same time, when the hardness of the ice layer is relatively stable, the card ball will be intermittently squeezed into the hydraulic chamber due to the collision between the drill barrel and the ice surface. At this time, the fluid inside the valve body 2 and the valve body 1 will move back and forth, and neither the valve body 2 nor the valve body 1 will produce The larger movement, and the valve body 1 and the valve body 2 will be in the limiting groove type in their respective chambers under the elastic force of the supporting springs at their respective bottoms. At this time, the gear sleeve will rotate at a medium speed, and after the drill barrel encounters the change in the hardness of the ice layer, it will sense and change the speed again. In summary, the hardness of the ice layer drilled by the drill barrel at this moment can be automatically judged by the matching of each card ball and the card groove, and the required speed can be automatically adjusted. At the same time, the volume of hydraulic oil between each valve body and each limiting groove can just enable the sliding magnet to move the length of a sun gear, so as to prevent the sliding spline from cooperating with the two sun gears at the same time, causing the sun gears to rotate at the same time but at different speeds and get stuck.

[0035] See also Figure 1 , 2, the outer surface of the drill barrel 1 is provided with a spiral groove, the end of the spiral groove is connected to the gear sleeve 4 pipeline, the interior of the drill barrel 1 and the bottom of the sawtooth 2 are provided with a drain port 3, a drain pipe is provided on one side of the gear sleeve 4, the drain pipe is connected to the drain port 3 pipeline, and an ore detector is also provided below the sawtooth 2. The drain port 3 inside the drill barrel 1 is connected with an auxiliary pipeline, an auxiliary box is provided at the end of the auxiliary pipeline, and a synchronous valve is provided in the middle of the auxiliary pipeline. The synchronous valve is connected to the gear sleeve 4 by a pipeline. During the drilling process of the drill barrel, the spiral groove can transport the ice slag generated at the sawtooth out of the drilling hole through the rotation of the drill barrel, and send the ice slag into the gear sleeve through the pipeline. The gears inside the gear sleeve will generate heat when moving, which can melt the ice slag. In the process of melting the ice slag, the melted water can not only cool the working gears, but also lubricate the gears when they are matched. In this way, there is no need to use lubricating oil, which can avoid the pollution of the Antarctic environment by the leakage of lubricating oil. At the same time, the melted water will be discharged into the drain port through the drain pipe, which can also be used in the drilling process. When the barrel rotates, a layer of liquid separation membrane is provided between the inner wall of the drill barrel and the icicle inside it, which can reduce the friction of the icicle on the inside of the drill barrel and reduce energy waste. When the melted water is discharged from the drain port, the auxiliary liquid in the auxiliary box will be discharged together through the synchronous valve. The auxiliary liquid can assist the work of the liquid separation membrane, making it less friction between the drill barrel and the icicle. At the same time, the rotation speed of the synchronous valve will be synchronized with the rotation speed of the gear sleeve. In this way, when the drill barrel drills quickly, the auxiliary liquid discharge is large, and conversely, when the drill barrel rotates slowly, the auxiliary liquid discharge is reduced. This can avoid the waste of auxiliary liquid and reduce the impact of auxiliary liquid on the Antarctic environment. After the drilling is completed, the water will re-freeze with the inner wall of the drill barrel at low temperature. At this time, the drill barrel can be taken out to remove the icicle inside it for research, without having to cut off the bottom of the icicle through other equipment, so that the scientific expedition team can reduce the carrying of tools and reduce the burden on personnel. At the same time, since the frozen water source is the melted water of the icicle itself, it will not affect the subsequent icicle research.

[0036] At the same time, an ore detector and a drain are installed at the front end of the saw teeth. There are also ores in the Antarctic ice layer. These ores are of great significance to the study of the Antarctic ice layer, so they need to be taken out completely. When the ore detector detects the existence of ore directly under the drill barrel, the entire device will stop moving forward, and at the same time, the drain at the front end of the saw teeth will discharge the melted water between the gears. This water absorbs the high temperature generated when the gears mesh and the temperature rises. This hot water will melt the ice layer directly under the drill barrel until the ore falls from the original ice layer to the melted ice layer. In the water hole, the drilling equipment will continue to drill down. At this time, since hot water will only be discharged from the saw teeth, the melted water hole will only exist directly below the saw teeth. When the drill barrel continues to drill down, the drill barrel will collect the fallen ore and water inside the drill barrel. Then, under the low temperature of the surrounding environment, these water and ore will re-solidify, so that the drill barrel can bring the ore out of the ground intact. At the same time, when the drill barrel stops moving due to excessive resistance, the hot water discharged in front of the saw teeth can prevent the drill barrel from solidifying with the surrounding ice layer, which is convenient for subsequent starting;
