Description

Technical Field

[0001] The invention relates to the technical field of oil replenishment for a sintering trolley, in particular to a wheel oil replenishment robot. Background Art

[0002] The sintering trolley is the main operating component of the sintering machine, used for material transportation and support during the sintering process. The sintering trolley is usually composed of a metal frame with a refractory platen on it to withstand high temperatures. The reason why the wheels of the sintering trolley need to be regularly re-oiled is mainly due to the harsh working conditions during operation. The sintering trolley wheel bearings work in harsh environments such as high temperature, heavy load, impact vibration, dust scouring and water scouring for a long time. These factors will cause the grease performance of the bearings to decrease, thereby accelerating the wear and damage of the bearings. In order to ensure the normal operation of the trolley wheel bearings and extend their service life, they need to be regularly re-oiled to keep the bearings lubricated.

[0003] At present, there are generally two ways to add oil to the wheels of sintering trolleys. One is to tow the sintering trolley to the oiling area, that is, to set up an oiling area on one side of the working area, and to set up an oiling mechanical arm equipment in the oiling area. The mechanical arm aligns the oiling pipe with the oiling hole on the wheel, and then oiling is carried out. This oiling method requires the sintering trolley to be towed to the oiling area. During the oiling period, the sintering trolley is in a suspended state and cannot achieve 24-hour uninterrupted operation, which has a discount on time cost.

[0004] The other method is to set an auxiliary track on one side of the sintering trolley track. The auxiliary track is used for the movement of the oil replenishing robot arm equipment, so that the oil replenishing robot arm equipment and the sintering trolley move synchronously, that is, the sintering trolley is running while replenishing oil. Although this method ensures the operating efficiency of the sintering trolley, the accuracy of the oil filling pipe of the oil replenishing robot arm equipment needs to be taken into account. Therefore, the quality requirements of the robot arm equipment itself are high and the purchase cost is also high. At the same time, considering the harsh operating environment of the sintering trolley, this will also affect the accuracy of the visual recognition system of the robot arm equipment.

[0054] At the same time, considering the use scenario of the sintering trolley 1, which needs to face high temperature conditions, heat insulation facilities can be set on the oil storage component to protect the lubricating oil and the oil pressing mechanism.

[0055] Reference Figure 1 - Figure 6Each of the pipeline systems includes: a transverse pipe 8, which is connected to the lower end of the oil outlet pipe 7; a plurality of groups of branch pipes 9 are branched below the transverse pipe 8; a plurality of groups of branch pipes 9, the upper end of each group of branch pipes 9 is connected to the transverse pipe 8, and the lower end of each group of branch pipes 9 is connected to an actuator component; the transverse pipe 8 is connected to multiple oil storage tanks 4 through the oil outlet pipe 7 upward, and the transverse pipe 8 is connected to multiple actuator components through the branch pipe 9 downward, so that the wheel 2 oil replenishing robot can replenish oil to multiple wheels 2 at the same time, and each wheel 2 can be replenished with oil within the same time period, ensuring that the matching conditions of each wheel 2 and the axle 17 tend to be the same, which helps to improve the operating stability of the sintering trolley 1.

[0056] Reference Figure 1 - Fig. 9 The actuator assembly includes: a C-shaped oil storage shell 10, a plurality of piston chambers 11 are arranged in the oil storage shell 10, each piston chamber 11 is provided with a piston body 13 connected by a spring 12, and each piston chamber 11 is provided with an oil inlet 14 and an oil outlet 15; each of the oil inlet 14 is connected to the branch pipe 9; each of the oil outlets 15 is connected to a short tube 16, and the end of the short tube 16 is connected to the axle 17 of the sintering trolley 1; a plurality of plug holes 18 are arranged on the outer ring of the end of the axle 17, and the plug holes 18 are connected to the short tube 16, an oil passage 19 is arranged at the axis position of the end of the axle 17, one end of the oil passage 19 is connected to the plug hole 18, and a plurality of oil injection holes 20 are also arranged on the outer ring of the end of the axle 17, and the oil injection hole 20 is arranged close to the end face of the axle 17, and the oil injection hole 20 is connected to the other end of the oil passage 19, and the oil outlet end of the oil injection hole 20 is close to the bearing on the axle 17; A protrusion 21 is provided on the inner end face of each wheel 2, and the protrusion 21 can squeeze the piston body 13, and the protrusion 21 is connected to the wheel 2 through a buffer assembly; the actuator assembly designed in this embodiment cooperates with the wheel 2 to operate; a protrusion 21 is provided on the inner side wall of the wheel 2, and when the wheel 2 rotates on the track, the wheel 2 also drives the protrusion 21 to rotate, and at this time the protrusion 21 will intermittently squeeze onto the outer end face of the piston body 13, and after the piston body 13 is squeezed, the piston body 13 retracts into the piston cavity 11, and at this time the piston body 13 squeezes the lubricating oil in the piston cavity 11 into the short tube 16, and then flows into the jack 18, and flows along the oil channel 19 to the position of the oil injection hole 20, and the lubricating oil is discharged from the oil injection hole 20 and injected into the bearing between the axle 17 and the wheel 2, so as to realize the lubrication of the bearing and ensure the smooth rotation between the wheel 2 and the axle 17;

[0057] A one-way valve is provided on each branch pipe 9, and the one-way valve on the branch pipe 9 limits the lubricating oil to be drawn from the branch pipe 9 into the piston chamber 11, and a one-way valve is also provided on the short pipe 16, and the one-way valve on the short pipe 16 limits the lubricating oil to be discharged from the piston chamber 11 into the short pipe 16, so as to ensure that the lubricating oil only has a positive flow, that is, the lubricating oil flows from the oil storage tank 4 to the inside of the wheel 2;

[0058] The wheel 2 drives the protrusion 21 to rotate and intermittently squeezes the outer end of the piston body 13. When the sintering trolley 1 stops running, the protrusion 21 also stops squeezing the piston body 13. At this time, the lubricating oil is also in a state of suspended replenishment, which avoids the lubricating oil being in a state of replenishment all the time, resulting in excess replenishment of the lubricating oil and causing waste.

[0059] Reference Figure 7 - Fig.12 The buffer assembly includes: an end shell 22, a sealing plate 23 is provided in the middle position of the end shell 22, an overflow hole 24 is provided in the center position of the sealing plate 23, a push plate 25 is connected to the bottom of the end shell 22 through a compression spring 26, and hydraulic oil is stored between the push plate 25 and the sealing plate 23; the port of the end shell 22 is opposite to the oil storage shell 10, and a protrusion 21 is sealingly and slidably connected in the port of the end shell 22, and hydraulic oil is stored between the protrusion 21 and the sealing plate 23; when the sintering trolley 1 is suspended from running, the lubricating oil is suspended from replenishing, at this time, the protrusion 21 is not opposite to the piston body 13, that is, the protrusion 21 and the piston body 13 are in an interlaced state; and the rotation and stop of the wheel 2 are in a random state, at this time, the wheel 2 stops rotating, the protrusion 21 is opposite to the piston body 13, and the piston body 13 squeezes the spring 12 connected to it, and at this time the spring The spring 12 is in a compressed state. If the sintering trolley 1 is in a suspended state for a long time, the spring 12 will be squeezed for a long time, which will affect the elastic force of the spring 12 and cause the piston body 13 to fail to work normally in the later stage. For this reason, a buffer component is provided; when the protrusion 21 and the piston body 13 are relatively squeezed, the elastic force of the spring 12 will squeeze the piston body 13 to move out of the piston cavity 11, and at the same time, the piston body 13 will squeeze the protrusion 21, and the protrusion 21 squeezes the hydraulic oil between it and the sealing plate 23. At this time, the hydraulic oil gradually flows along the overflow hole 24 into the cavity between the compression spring 26 and the sealing plate 23, that is, the protrusion 21 moves part of the stroke into the end shell 22, so as to relieve the tight state of the compressed spring 12 and reduce the amount of compression of the spring 12 to protect the spring 12, so that the actuator can work normally for a long time.

[0060] Reference Fig.10 , a recess 27 is provided on the end face of each of the protrusions 21, and a plurality of rotation grooves are provided on the inner surface of the recess 27, in which a roller body 28 is rotatably connected, and the outer end face of the piston body 13 can slide into the recess 27 and can rub the roller body 28 to rotate; when the protrusion 21 and the piston body 13 are relatively squeezed, the relative sliding squeeze between the protrusion 21 and the piston body 13 is converted into a linear motion of the piston body 13, which will cause wear of the contact point of the protrusion 21 or the piston body 13, and if the protrusion 21 or the piston body 13 is in a worn state for a long time, the protrusion 21 or the piston body 13 will lose its function. For this reason, a roller body 28 is arranged at the end face position of the protrusion 21, and the relative sliding contact between the protrusion 21 and the piston body 13 is converted into a rolling contact between the roller body 28 and the piston body 13, thereby reducing resistance and wear, and extending the service life of the protrusion and the piston body 13.

[0061] Reference Figure 1 - Figure 4 The protection component includes a guard plate 29, which covers the oil storage component and the pipeline system, and the upper and lower edges of the guard plate 29 are fixed to the outer side wall of the basket; the guard plate 29 is arranged on the basket 3, covers the oil storage component and the pipeline system, and can protect the oil storage component and the pipeline system from being hit by foreign objects falling from the outside.

If the lubricating oil flows on the wheel 2 and the track, it will cause the sintering trolley 1 and the track to slip, or the traction vehicle and the track to slip. For this purpose, an oil guide plate 30 is arranged, and the oil guide plate 30 is attached to the inner side wall of the wheel 2 and will not interfere with the protrusion 21. The lubricating oil overflowing from between the wheel 2 and the axle 17 flows on the oil guide plate 30, and then flows between two adjacent tracks along the guide plate without adhering to the track.

[0063] Reference Figure 8 An oil guide channel 31 is provided inside the wheel 2, one end of the oil guide channel 31 is opposite to the oil injection hole 20 on the axle 17, and the other end of the oil guide channel 31 is arranged opposite to the bearing end surface in the wheel 2; by providing the oil guide channel 31, the lubricating oil discharged from the oil injection hole 20 is guided so that the lubricating oil can be accurately injected into the bearing. Even if a small amount of lubricating oil is injected, the lubricating oil can fully act on the bearing, thereby saving the lubricating oil.

[0064] Reference Fig.11 The outer end of the piston body 13 is provided with a rotation groove, and a ball 32 is arranged in the rotation groove; the ball 32 is arranged on the outer end surface of the piston body 13, which can reduce the wear of the piston body 13 itself and extend the service life of the piston body 13.

[0066] The lubricating oil is stored in the oil storage component. When the sintering trolley 1 is running, the wheel 2 rotates, and the wheel 2 drives the execution component to run. The execution component extracts the lubricating oil in the oil storage component and injects it into the connection position between the axle 17 and the wheel 2 to replenish the lubricating oil. The wheel 2 oil replenishing robot can replenish the lubricating oil when the sintering trolley 1 is running, and there is no need to move the sintering trolley 1 to the oil replenishing area to replenish the oil, so as not to affect the working efficiency of the sintering trolley 1. At the same time, there is no need to spend a high price to purchase high-precision mechanical arm equipment, which saves costs. Moreover, the wheel 2 oil replenishing robot designed in this embodiment can operate in harsh environments and has strong adaptability.

[0067] An oil pressing mechanism is arranged on the oil storage tank 4, and the oil pressing mechanism includes a cover plate 33, and the cover plate 33 covers the upper port of the oil storage tank 4. An operating motor 34 is arranged on the upper surface of the cover plate 33, and a screw rod 35 is fixedly connected to the output end of the operating motor 34, and the screw rod 35 extends into the oil storage tank 4. A pressing plate 36 is arranged in the oil storage tank 4, and the screw rod 35 can rotate to transmit the pressing plate 36 to move up and down, and squeeze the lubricating oil in the oil storage tank 4 into the pipeline system; the operating motor 34 is controlled to rotate, and the operating motor 34 drives the screw rod 35 to rotate, and the screw rod 35 pushes the pressing plate 36 downward, The edge of the pressing plate 36 is closely attached to the inner wall of the oil storage tank 4. The pressing plate 36 presses down the lubricating oil, which can press the liquid lubricating oil into the pipeline system, and can also squeeze the paste lubricating oil into the pipeline system, which can be applicable to lubricating oil in various states; the lubricating oil is pressed into the oil outlet pipe 7, and then flows into the pipeline system; a connecting pipe 6 is arranged between two adjacent oil storage tanks 4, which plays the role of connecting them into a whole, and secondly, when replenishing the lubricating oil into the oil storage tanks 4, only one of the oil storage tanks 4 needs to be replenished to replenish the oil in multiple oil storage tanks 4;

[0068] At the same time, considering the use scenario of the sintering trolley 1, which needs to face high temperature, a heat insulation facility can be set on the oil storage component to protect the lubricating oil and the oil pressing mechanism;

[0069] The transverse pipe 8 is connected to multiple oil storage tanks 4 upwards through the oil outlet pipe 7, and is connected to multiple actuators downwards through the branch pipe 9, so that the wheel 2 oil replenishing robot can replenish oil to multiple wheels 2 at the same time, and each wheel 2 can be replenished with oil in the same time period, ensuring that the matching conditions of each wheel 2 and the axle 17 tend to be the same, which helps to improve the running stability of the sintering trolley 1;

[0070] A protrusion 21 is provided on the inner side wall of the wheel 2. When the wheel 2 rotates on the track, the wheel 2 also drives the protrusion 21 to rotate. At this time, the protrusion 21 will intermittently squeeze the outer end surface of the piston body 13. After the piston body 13 is squeezed, the piston body 13 retracts into the piston cavity 11. At this time, the piston body 13 squeezes the lubricating oil in the piston cavity 11 into the short tube 16, and then flows into the plug hole 18 and flows along the oil channel 19 to the position of the oil injection hole 20. The lubricating oil is discharged from the oil injection hole 20 and injected into the bearing between the axle 17 and the wheel 2 to achieve lubrication of the bearing and ensure the smooth rotation between the wheel 2 and the axle 17.

[0071] A one-way valve is provided on each branch pipe 9, and the one-way valve on the branch pipe 9 limits the lubricating oil to be drawn from the branch pipe 9 into the piston chamber 11, and a one-way valve is also provided on the short pipe 16, and the one-way valve on the short pipe 16 limits the lubricating oil to be discharged from the piston chamber 11 into the short pipe 16, so as to ensure that the lubricating oil only has a positive flow, that is, the lubricating oil flows from the oil storage tank 4 to the inside of the wheel 2;

[0072] The wheel 2 drives the protrusion 21 to rotate and intermittently squeezes the outer end of the piston body 13. When the sintering trolley 1 stops running, the protrusion 21 also stops squeezing the piston body 13. At this time, the lubricating oil is also in a state of suspended replenishment, which prevents the lubricating oil from being replenished all the time, resulting in excess replenishment of the lubricating oil and causing waste;

[0073] As mentioned above, when the sintering trolley 1 is suspended, the lubricating oil is not replenished. At this time, the protrusion 21 is not opposite to the piston body 13, that is, the protrusion 21 and the piston body 13 are in a staggered state; and the rotation and stop of the wheel 2 are random. At this time, the wheel 2 stops rotating, the protrusion 21 is opposite to the piston body 13, and the piston body 13 squeezes the spring 12 connected thereto. At this time, the spring 12 is in a compressed state. If the sintering trolley 1 is in a suspended state for a long time, the spring 12 will also be squeezed for a long time, which will affect the elastic force of the spring 12, resulting in the piston body 13 being unable to work normally in the later stage. For this purpose, a buffer component is provided; when the protrusion 21 and the piston body 13 are pressed relative to each other, the elastic force of the spring 12 will squeeze the piston body 13 to move out of the piston cavity 11, and at the same time the piston body 13 will squeeze the protrusion 21, and the protrusion 21 squeezes the hydraulic oil between it and the blocking plate 23, at this time, the hydraulic oil gradually flows into the cavity between the compression spring 26 and the blocking plate 23 along the overflow hole 24, that is, the protrusion 21 moves part of the stroke into the end shell 22, so as to relieve the tension state of the compressed spring 12, reduce the amount of compression of the spring 12, and protect the spring 12, so that the actuator can work normally for a long time;

[0074] When the protrusion 21 and the piston body 13 are relatively squeezed, the relative sliding squeeze between the protrusion 21 and the piston body 13 is converted into the linear motion of the piston body 13, which will cause wear of the contact point of the protrusion 21 or the piston body 13, and the protrusion 21 or the piston body 13 will lose its function if it is in a worn state for a long time. A roller body 28 is arranged at the end surface position of the protrusion 21 to convert the relative sliding contact between the protrusion and the piston body 13 into a rolling contact between the roller body 28 and the piston body 13, thereby reducing resistance and wear, and extending the service life of the protrusion and the piston body 13; the guard plate 29 is arranged on the vehicle basket 3, covering the oil storage assembly and the pipeline system, and can protect the oil storage assembly and the pipeline system from being hit by foreign objects falling from the outside;

[0075] Excess lubricating oil will flow out along the gap between the axle 17 and the wheel 2. If the lubricating oil flows on the wheel 2 and the track, it will cause slippage between the sintering trolley 1 and the track, or between the traction vehicle and the track. For this purpose, an oil guide plate 30 is provided. The oil guide plate 30 is attached to the inner wall of the wheel 2 and will not interfere with the protrusion 21. The lubricating oil overflowing from between the wheel 2 and the axle 17 flows on the oil guide plate 30, and then flows between two adjacent tracks along the guide plate without being attached to the track.

[0076] By setting up the oil guide channel 31, the lubricating oil discharged from the oil injection hole 20 is guided so that the lubricating oil can be accurately injected into the bearing, that is, a small amount of lubricating oil is injected, and the lubricating oil can fully act on the bearing, which saves the lubricating oil; the ball 32 is set on the outer end surface of the piston body 13, which can reduce the wear of the piston body 13 itself and extend the service life of the piston body 13.

[0077] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
