Description

Technical Field

[0001] The invention relates to the field of steel processing equipment, and in particular to a wheel cleaning and oiling system for a sintering trolley. Background Art

[0002] Sintering is an important part of the steel production process. It is made by mixing iron ore powder, anthracite (powder) and lime, blast furnace dust, rolling mill skin and steel slag in a certain ratio, and then sending them to the sintering system to sinter the sintered ore with sufficient strength and particle size, which is used as clinker for ironmaking. Reasonable use of sintered clinker for ironmaking is of certain significance for improving the utilization coefficient of blast furnace, reducing coke ratio, improving blast furnace permeability and ensuring blast furnace operation.

[0003] During the sintering process, a sintering trolley is usually used as the transportation equipment for the above materials. It forms a running rotary chain between the head and tail wheels of the sintering machine, receives the sintering mixed material in the upper horizontal section, and after preheating, ignition, sintering, cooling, and turning, it is sent to the blast furnace area and returns to the head wheel to form a transmission cycle;

[0004] The sintering trolley is usually composed of dozens of sintering trolleys connected in sequence and running along the track. Each sintering trolley includes a trolley body and a wheel system, and the wheel system is composed of a bushing, a wheel axle and a wheel, wherein the bushing is welded to the trolley body and has an interference fit with the wheel axle, and the wheel is installed on the wheel axle through a bearing assembly. The oil filling port on the outer end face of the wheel axle leads to the bearing assembly, and each adjacent wheel is equidistantly arranged. This type of wheel system structure can provide sufficient load-bearing effect for each trolley body, and its load-bearing stability has been fully verified. The sintering trolley has dozens to hundreds of sets of the above-mentioned wheel systems, which run smoothly on the track through these wheel systems, thereby ensuring the operation of the entire sintering trolley.

[0005] However, in the actual production process, due to the structural limitations of the sintering trolley, it will cause failures in the transmission process of the sintering system. The existing way of oiling the sintering trolley is to manually oil the sintering trolley when it is not in operation, and to clean and maintain it after operation. However, with this method, the dust such as iron powder and iron filings caused by the transmission of the sintering trolley, as well as the dry matter formed by the lubricating oil mixed with dust under high temperature conditions, are easy to enter the bearing assembly along the wheel oil cup of the oil filling port during the injection of lubricating oil, which not only easily causes inadequate lubrication of the bearing assembly, but also causes wear of the wheel axle; and the sintering trolley in a hot operating environment, when the wheel system is worn, is more likely to cause deformation of the wheel components of the sintering trolley and accelerate the wear of the wheel axle, which can eventually lead to wheel locking, and finally the wheel axle has to be replaced.

[0006] In addition, since the wheel axle and the sleeve have an interference fit, and the sleeve is welded to the trolley body, the entire sintering trolley usually needs to be lifted off the track to replace the new sintering trolley, which makes the replacement of the wheel axle time-consuming. At the same time, since the wheel axle and the sleeve have an interference fit, destructive force disassembly is generally used in the process of replacing the worn wheel axle. Forced disassembly not only further damages the wheel axle, but also damages the sleeve, which in turn increases the maintenance cost of the wheel axle;

[0007] At present, some relevant technical personnel are making modifications to the wheel system structure, but this will inevitably cause a certain degree of change in the load-bearing effect of the sintering trolley, so the sintering system as a whole needs to be debugged accordingly; if the structural modification reduces the load-bearing capacity and stability, it is more likely to lead to a decrease in the overall production efficiency; and the equipment modification of a large number of sintering trolleys requires a higher equipment modification cost.

[0008] In summary, how to prevent the wear and damage of the wheel system caused by dust such as iron powder and iron filings at a lower cost while retaining the original sintering trolley wheel system, and provide sufficient lubrication for the wheel system to minimize the disadvantages of high maintenance and repair costs of the wheel system, is a technical problem that needs to be urgently solved by technical personnel in this field.

[0027] The present invention has the following benefits:

[0028] 1. The rotating disk of the vehicle body speed measuring system is pressed against the wall against the sintering trolley. The moving sintering trolley drives the rotating disk to rotate. The rotating disk is fed back to the speed measuring encoder through the transmission device to obtain the moving speed of the sintering trolley. The moving speed of the sintering trolley fed back to the control system is more accurate; combined with the visual sensor to sequentially detect the information of the pre-positioned wheels entering and exiting the detection area, it can provide more accurate data for the subsequent conversion of the dynamic coordinate position of the oil filling port to be cleaned and the dynamic coordinate position of the oil filling port to be filled, and provide accurate adjustment and control for the subsequent cleaning process of the wheel cleaning system and the oiling process of the wheel oiling system;

[0029] 2. Based on the accurate dynamic coordinate position of the oil filling port to be cleaned, the wheel cleaning system can ensure that the cleaning time of the wheel to be cleaned does not exceed the time for the pre-positioned wheel to enter and exit the detection area, thereby preventing the oil filling port of the wheel to be cleaned from interfering with the wheel cleaning system when the wheel to be cleaned leaves the cleaning operation area, thereby causing damage to the wheel cleaning system; and, by adopting a control system to control the longitudinal pushing mechanism to push the pushing seat toward the wheel oil filling port, and controlling the rotating shaft of the rotating motor to drive the flexible cleaning brush to rotate, the rotating motor 314 can clean the dust such as iron powder and iron filings near the oil filling port, as well as the dry matter formed by the lubricating oil mixed with dust within a few seconds at a relatively high rotation speed, and its cleaning efficiency is more efficient, and it can effectively prevent and reduce the dust such as iron powder and iron filings and the dry matter formed by the lubricating oil mixed with dust from adhering to the oil filling port, and entering the wheel axle and bearing components through the oil filling port during subsequent oil injection, thereby causing wear;

[0030] 3. Based on the accurate dynamic coordinate position of the oil filling port to be filled, the wheel oil filling system can ensure that the oil filling time of the wheel to be filled does not exceed the time of the pre-positioned wheel entering and exiting the detection area, preventing the oil filling port of the wheel to be filled from interfering with the wheel oil filling system when the wheel to be filled leaves the oil filling operation area, thereby causing damage to the wheel oil filling system; and, a control device is used to control the mechanical arm to drive the direction-changing fine-tuning device and the oil filling pipe to move to the position of the oil filling port of the wheel to be filled, and the oil filling pipe is connected to the oil filling port of the wheel to be filled according to the vehicle speed measured by the vehicle speed measurement system, so as to track and fill the oil, so as to make the oil filling of the wheel system more sufficient and effective, and at the same time prevent dust from entering the lubrication parts of the vehicle body such as the wheel axle and bearing parts through the oil filling port;

[0031] 4. Through the elastic force of the shock absorbing spring of the shock absorbing mechanism, the shock absorbing mechanism is pressurized and shock-absorbed when the oil filling pipe is connected to the oil filling port of the wheel to be oiled, and elastic pressing force is provided. The oil filling pipe can be connected to the oil filling port of the wheel to be oiled with a more stable connection effect, avoiding the phenomenon of inaccurate connection caused by the shaking of the sintering trolley during operation.

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is specifically described in the following embodiments in conjunction with the accompanying drawings. Example

[0037] like Figure 1-4 As shown, a wheel cleaning and oiling system for a sintering trolley comprises a vehicle body speed measuring system 1, a visual sensor 2, a wheel cleaning system 3, a wheel oiling system 4, and a control system 5, wherein one wheel cleaning system 3 and one wheel oiling system 4 are correspondingly arranged on both sides of the sintering trolley travel track; and, the wheel cleaning and oiling system of the sintering trolley is arranged on both sides of the track between the unloading process equipment and the preheating process equipment, or on both sides of the track between the cooling process equipment and the blast furnace, and the sintering trolley moves forward along the track at a constant speed.

[0038] Along the positions successively reached by the sintering trolley, the vehicle body speed measuring system 1 is arranged at the front end of the visual sensor 2, the wheel cleaning system 3, and the wheel cleaning system 3, and the visual sensor 2 is installed at the upper end of the wheel cleaning system 3 through the adjustable bracket 23; the wheel oiling system 4 is arranged at the rear end of the wheel cleaning system 3;

[0039] See also Figure 1 , 2 The vehicle body speed measuring system 1 includes an adjusting device, a rotating disk 10, a transmission device, and a speed measuring encoder 14, wherein the adjusting device is composed of a position adjusting mechanism, a fixed bracket 11, a swing bracket 12, and a spring member 13, wherein the swing bracket 12 is hinged to the fixed bracket 11 through a hinge structure; the rotating disk 10 is axially connected to the swing end of the swing bracket 12, and the position adjusting mechanism adjusts the contact position between the rotating disk 10 and the sintering trolley; the spring member 13 connects the fixed bracket 11 and the swing bracket 12, and the swing bracket 12 swings the swing end of the swing bracket 12 toward the sintering trolley under the elastic force of the spring member 13, so that the rotating disk 10 continuously presses against the wall of the sintering trolley; the speed measuring encoder 14 is arranged on the side away from the sintering trolley;

[0040] The position adjustment mechanism provides an effect that the vehicle body speed measuring system 1 can adapt to the use of sintering trolleys of different standard sizes. For example, in this embodiment, the position adjustment mechanism is composed of a position coarse adjustment mechanism and a position fine adjustment mechanism, and the contact position between the rotating disk 10 and the sintering trolley can be coarsely adjusted and finely adjusted, wherein:

[0041] The fixed support 11 is a vertical fixed support sub-component 111 and a longitudinal fixed support sub-component 112 provided with a longitudinal adjustment fixing member 113 and a vertical adjustment fixing member 114. The position coarse adjustment mechanism composed of the longitudinal adjustment fixing member 113 and the vertical adjustment fixing member 114 can make the longitudinal fixed support sub-component 112 relatively largely adjusted in longitudinal distance and vertical distance relative to the vertical fixed support sub-component 111, so that the contact position between the rotating disk 10 and the sintering trolley can be adjusted to a large extent.

[0042] The hinged structure is composed of a sliding groove 16 arranged on the fixed bracket 11 and an adjustable swing bolt 17 arranged on the swing bracket 12. The adjustable swing bolt 17 is inserted into the sliding groove 16 in an adjustable manner. The swing bracket 12 swings relative to the fixed bracket 11 along the adjustable swing bolt 17. The position fine-tuning mechanism formed by the hinged structure can make the swing bracket 12 slightly adjusted in distance through the adjustable swing bolt 17, so that the contact position of the rotating disk 10 and the sintering trolley can be adjusted relatively accurately.

[0043] The speed encoder 14 is arranged on a side away from the sintering trolley to protect the speed encoder 14, so as to avoid the influence of the heat radiation of the sintering trolley loaded with the sintering mixed material on the function of the speed encoder 14 and the speed measurement accuracy. In order to more accurately transmit the rotation speed of the rotating disk 10 to the speed encoder 14 through the input shaft of the speed encoder 14, the transmission device of this embodiment is composed of a transmission belt 15 connecting the rotating disk 10 and the input shaft of the speed encoder 14. While being able to achieve the above-mentioned accurate measurement effect, it has a simple structure and high durability.

[0044] By adjusting the position of the rotating disk 10 by the position adjustment mechanism, the rotating disk 10 can be pressed against the wall of the sintering trolley, and the sintering mixed material attached to the sintering trolley, or the uneven parts of the body body, or the small width difference between the body side walls between the sintering trolleys, can be made to swing the swing end of the swing bracket 12 toward the sintering trolley under the elastic force of the spring member 13, so that the swing end of the swing bracket 12 applies force to the rotating disk 10, so that the rotating disk 10 can be adjusted accordingly with the fluctuation of the body side wall of the sintering trolley during the movement of the sintering trolley, and the rotating disk 10 keeps pressing against the body side wall of the sintering trolley. Therefore, the moving sintering trolley drives the rotating disk 10 to rotate, and the rotating disk 10 is fed back to the speed encoder 14 through the transmission device to obtain the moving speed of the sintering trolley, and the moving speed of the sintering trolley is fed back to the control system 5.

[0045] See also Figure 1 , 3 In this embodiment, the visual sensor 2 is composed of two visual sensor units (21, 22), wherein the first visual sensor unit 21 sequentially detects information of the pre-positioned wheel 81 entering the detection area, and the second visual sensor unit 22 sequentially detects information of the pre-positioned wheel 81 leaving the detection area. The pre-positioned wheel 81 sensed by the above two visual sensor units (21, 22) is the next wheel to be prepared to enter the cleaning operation area of ​​the wheel cleaning system 3; the visual sensor 2 composed of the above two visual sensor units (21, 22) installed on the adjustable bracket 23 can sequentially detect information of the pre-positioned wheel 81 entering and leaving the detection area, and feed it back to the control system 5;

[0046] Since the oil filling port is set at the center of the wheel, the control system 5 converts the dynamic coordinate position of the oil filling port to be cleaned and the dynamic coordinate position of the oil filling port to be filled with oil according to the moving speed of the sintering trolley and the information of the pre-positioned wheel 81 entering and exiting the detection area. In addition, since the rotating disk 10 is fed back to the speed measuring encoder 14 through the transmission device to obtain the moving speed of the sintering trolley, the moving speed of the sintering trolley fed back to the control system 5 is more accurate; combined with the visual sensor to detect the information of the pre-positioned wheel 81 entering and exiting the detection area twice, it can provide more accurate data for the subsequent conversion of the dynamic coordinate position of the oil filling port to be cleaned and the dynamic coordinate position of the oil filling port to be filled with oil, and provide accurate adjustment and control for the subsequent cleaning process of the wheel cleaning system 3 and the oiling process of the wheel oiling system 4;

[0047] The wheel cleaning system 3 includes a driving device 31 and a flexible cleaning brush 32. In the present embodiment, the driving device 31 is composed of a longitudinal pushing cylinder 311, a longitudinal pushing mechanism formed by a longitudinal guide rail 312, and a rotating motor 314. The rotating motor 314 is arranged on a pushing seat 313 of the longitudinal pushing cylinder 311, and the rotating shaft 315 of the rotating motor 314 is directed toward the wheel oil filling port. The flexible cleaning brush 32 is arranged on the rotating shaft 315 of the rotating motor 314. The flexible cleaning brush 32 can be made of a flexible material having a certain toughness and elasticity, such as a flexible wire brush; it can be suitable for cleaning dust such as iron powder and iron filings; or a porous, wear-resistant, loose and flexible material such as an industrial scouring pad suitable for metal cleaning can be used, which can be suitable for cleaning dry objects formed by lubricating oil mixed with dust; of course, a combined flexible cleaning brush 32 formed by a combination of two types of flexible materials can be reasonably used to effectively clean the above-mentioned dirt;

[0048] When the dynamic coordinate position of the oil filling port to be cleaned enters the cleaning operation area, the control system 5 controls the longitudinal push cylinder 311 to push the push seat 313 along the longitudinal guide rail 312 to move toward the wheel oil filling port, and controls the rotating shaft 315 of the rotating motor 314 to drive the flexible cleaning brush 32 to rotate. The rotating motor 314 can clean the dust such as iron powder and iron filings near the oil filling port and the dry matter formed by the lubricating oil mixed with dust within a few seconds at a relatively high rotation speed, and cooperate with the retraction action of the longitudinal push cylinder 311 to control the push seat 313 to reset and move away from the wheel, thereby completing the cleaning of the oil filling port of the wheel 82 to be cleaned; it can make the wheel cleaning system 3 clean the wheel 82 to be cleaned for a cleaning time not exceeding the time for the pre-positioned wheel 81 to enter and exit the detection area, thereby preventing the oil filling port of the wheel 82 to be cleaned from interfering with the wheel cleaning system 3 when the wheel 82 to be cleaned leaves the cleaning operation area, thereby causing damage to the wheel cleaning system 3.

[0049] When each wheel enters the cleaning operation area in turn, the control system 5 controls the wheel cleaning system 3 to repeat the above steps in turn according to the dynamic coordinate position of the oil filling port to be cleaned of each wheel. The control system 5 can control the driving device 31 to drive the flexible cleaning brush 32 to clean the wheel oil filling port in turn and in a direction. When the sintering trolley circulates along the track to the cleaning operation area of ​​the wheel cleaning system 3, each wheel can be automatically cleaned, thereby effectively preventing and reducing the wear of the sintering trolley wheel system by dust such as iron powder and iron chips and dry matter formed by lubricating oil mixed with dust.

[0050] After the oil filling port of the wheel to be cleaned 82 completes the cleaning process, it continues to move into the oil filling operation area of ​​the wheel oil filling system 4 to perform the subsequent oil filling process.

[0051] See also Figure 1 , 4In this embodiment, the wheel oiling system 4 includes a mechanical arm 41 with a moving part, a direction-changing fine-tuning device 42 arranged at the end of the mechanical arm 41, and an oiling pipe 44. The direction-changing fine-tuning device 42 is composed of a bearing seat 420, a lateral fine-tuning mechanism, a longitudinal fine-tuning mechanism, and a shock-absorbing mechanism 43. The longitudinal fine-tuning mechanism is a longitudinal pneumatic spring 421 installed on the bearing seat 420 by a push rod; the lateral fine-tuning mechanism is composed of a bearing plate 422 installed on the seat of the longitudinal pneumatic spring 421, a lateral guide rail 423 arranged on the bearing plate 422, and a pair of oppositely arranged lateral cylinders 424 driving the lateral slide 425 to slide along the lateral guide rail 423; the shock-absorbing mechanism 43 is an oiling pipe fixing seat 431 arranged on the lateral slide 425, an oiling pipe 44 connected to the oiling device, and a shock-absorbing spring 433 sleeved on the oiling pipe 44 and located between the oiling pipe fixing section 432 and the oiling pipe fixing seat 431.

[0052] According to the dynamic coordinate position of the oil filling port to be filled with oil, the control device controls the mechanical arm 41 to drive the direction-changing fine-tuning device 42 and the oil filling pipe 44 to move to the oil filling port position of the wheel 83 to be filled with oil; and because the sintering trolley moves along the track and the oil filling takes a certain amount of time, the mechanical arm 41 can be positioned more accurately in the vertical direction, and in the moving direction of the sintering trolley, that is, the lateral moving direction in this embodiment, it is necessary to connect the oil filling pipe 44 to the oil filling port of the wheel 83 to be filled with oil according to the vehicle speed measured by the vehicle body speed measurement system 1, and then follow the oil filling. Therefore, the longitudinal space fine-tuning is performed by using the longitudinal pneumatic spring 421 of the longitudinal fine-tuning mechanism to output sufficient pressing force; and through the elastic force of the shock-absorbing spring 433 of the shock-absorbing mechanism 43, the shock-absorbing mechanism 43 is compressed and damped when the oil filling pipe 44 is connected to the oil filling port of the wheel 83 to be filled with oil, and an elastic pressing force is provided to keep the oil filling pipe 44 stably connected to the oil filling port of the wheel 83 to be filled with oil;

[0053] At the same time, as the sintering trolley moves along the track, the end of the robot arm 41 moves in coordination with the moving speed of the sintering trolley, and slides along the transverse slide 425 and the transverse guide rail 423 through a pair of oppositely arranged transverse cylinders 424 to perform transverse spatial fine-tuning, so that the oil filling pipe 44 can stably aim at the oil filling port of the wheel 83 to be oiled and fully inject lubricating oil to complete the full lubrication of the sintering trolley wheel system without the oil filling pipe 44 and the oil filling port being offset and causing lubricating oil leakage.

[0054] The above-mentioned wheel oiling system 4 operates stably. After the oiling pipe 44 directionally tracks and oils the oiling port of the wheel 83 to be oiled, the control system 5 controls the mechanical arm 41 to drive the oiling pipe 44 to reset, so that the oiling time of the wheel 83 to be oiled by the wheel oiling system 4 does not exceed the time of the pre-positioned wheel 81 entering and exiting the detection area, thereby preventing the oiling port of the wheel 83 to be oiled from interfering with the wheel oiling system 4 when the wheel 83 to be oiled leaves the oiling operation area, thereby causing damage to the wheel oiling system 4.

[0055] When each wheel enters the oiling operation area in turn, the control system 5 controls the wheel oiling system 4 in turn according to the dynamic coordinate position of the oiling port of each wheel to be oiled, and repeats the above steps. The control device can control the mechanical arm 41 and the direction-changing fine-tuning device 42 to drive the oiling pipe 44 to track and oil the oiling port in turn and in a directionally manner. When the sintering trolley circulates along the track to the oiling operation area of ​​the wheel oiling system 4, the automatic oiling of each wheel can be automatically completed, thereby significantly reducing the leakage of lubricating oil attached to the wheels and the oiling ports due to high temperature drying, and the adhesion of iron powder and iron filings to form dust that is difficult to clean. Dry matter enters the wheels, axles, and axle sleeves with the lubricating oil, thereby avoiding wear on the sintering trolley wheel system.

[0056] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
