[0031] The preferred embodiments of the present application are described below in conjunction with the drawings, and it should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.
[0032] In conjunction with Figures 1-4 shown, according to the embodiments of the present application, a focus tank trolley running mechanism suitable for a curved channel is provided, comprising:
[0033] A frame 1;
[0034] Wheels 2, a plurality of wheels 2 are arranged at the bottom of the frame 1, and the hub of the wheel 2 and the track contact end are sequentially provided with an inclined area 21 and a connecting area 22;
[0035] A heart disc structure 3 is arranged on the frame 1, and the heart disc structure 3 comprises an upper heart disc 31 and a lower heart disc 32, and an adjusting structure 33 is arranged between the upper heart disc 31 and the lower heart disc 32, for generating rolling friction between the upper heart disc 31 and the lower heart disc 32.
[0036] Specifically, the frame 1 is made of high-strength steel material, has good load-carrying capacity and structural stability, and can safely and reliably carry the weight of the coke pot and the red coke. In actual production, in the face of frequent transportation operations and complex working conditions, the solid structure of the frame 1 can effectively resist various stresses and impacts, ensuring the long-term stable operation of the coke pot trolley.
[0037] The wheels 2 are installed at the bottom of the frame 1, and the number is reasonably set according to the actual load-carrying demand. Multiple wheels 2 work together to evenly share the weight borne by the frame 1, ensuring the stability of the coke pot trolley running. The hub of the wheel 2 is provided with an inclined area 21 and a connecting area 22 in sequence at the track contact end. The inclined area 21 adopts a specific inclination angle, which can make the wheel 2 better fit the curved track when the coke pot trolley runs on a curve, effectively dispersing the lateral force generated during vehicle running, avoiding the phenomenon of "rail biting" of the wheel 2 due to uneven stress, and greatly improving the safety and stability of the vehicle when running on a curve.
[0038] The heart disc structure 3 is arranged on the frame 1, and the heart disc structure 3 includes an upper heart disc 31 and a lower heart disc 32. An adjusting structure 33 is installed between the upper heart disc 31 and the lower heart disc 32. The adjusting structure 33 adopts rolling friction, for example, using high-precision ball or roller bearings, which can significantly reduce the friction between the upper heart disc 31 and the lower heart disc 32 compared with the traditional sliding friction method. During the turning of the coke pot trolley, it can bear very large axial load and radial load, ensuring that the frame 1 can smoothly turn when running on a curve, greatly improving the safety during turning.
[0039] In actual use, when the coke pot trolley runs on a red coke unloading route with a curve with a small turning radius, the inclined area 21 of the wheel 2 closely fits the track, effectively coping with the lateral force brought by the curve, and the adjusting structure 33 in the heart disc structure 3 can bear very large axial load and radial load. The two work together to enable the coke pot trolley to safely and stably pass through the curve, greatly reducing the risk of overturning of the trolley and the coke pot, meeting the transportation demand under complex unloading routes, improving production efficiency, and ensuring production safety.
[0040] The adjusting structure 33 is a thrust self-aligning roller bearing.
[0041] Specifically, the adjusting structure 33 adopts a thrust self-aligning roller bearing. The thrust self-aligning roller bearing has a unique spherical raceway and roller design, which can automatically align and adapt to the angle change of the frame 1 when running on a curve. The thrust self-aligning roller bearing not only can bear large axial load, but also can bear certain radial load, which is very suitable for the complex stress condition of the coke pot trolley when running on a curve.
[0042] When the coke oven trolley encounters a curve during driving, the thrust self-aligning roller bearing enables the upper disc 31 to rotate flexibly relative to the lower disc 32, effectively reducing the friction therebetween. This low-friction rotating mode enables the vehicle frame 1 to turn more smoothly, reducing the turning resistance and energy loss. Meanwhile, the automatic self-aligning function of the thrust self-aligning roller bearing can ensure that the vehicle wheels 2 always maintain good contact with the track, improving the driving stability and safety of the vehicle.
[0043] The adjusting structure 33 is coaxial with the upper disc 31 and the lower disc 32.
[0044] Specifically, the adjusting structure 33 is coaxial with the upper disc 31 and the lower disc 32, ensuring that the adjusting structure 33 can accurately transmit and disperse the acting force between the upper disc 31 and the lower disc 32 during the operation of the coke oven trolley. When the coke oven trolley drives on a curve, the thrust self-aligning roller bearing can better exert its automatic self-aligning function, enabling the upper disc 31 to rotate smoothly and flexibly relative to the lower disc 32. Not only can this effectively reduce the friction between the upper disc 31 and the lower disc 32, reducing energy loss and component wear, but also can ensure that the vehicle frame 1 can smoothly turn according to the predetermined trajectory when driving on a curve, avoiding safety hazards caused by poor turning.
[0045] The disc structure 3 further comprises:
[0046] A bearing cover plate 34 is arranged at the bottom of the upper disc 31.
[0047] A limiting plate 35 is arranged at the top of the lower disc 32, and a limiting groove is formed in the top of the lower disc 32. The first end of the limiting plate 35 is arranged on the bottom of the bearing cover plate 34, and the second end of the limiting plate 35 is at least partially arranged in the limiting groove.
[0048] Specifically, the bearing cover plate 34 is installed at the bottom of the upper disc 31. It not only protects the thrust self-aligning roller bearing from dust, debris and moisture, prolonging the service life of the bearing, but also enhances the structural strength of the upper disc 31, enabling it to better withstand pressure and torque.
[0049] A limiting groove is formed in the top of the lower disc 32, and the first end of the limiting plate 35 is fixed to the bottom of the bearing cover plate 34, and the second end is at least partially arranged in the limiting groove. When the coke oven trolley drives on a curve, it can limit the excessive rotation of the upper disc 31 relative to the lower disc 32, preventing the two from being misaligned or separated, ensuring the normal operation of the disc structure 3. Meanwhile, when the trolley is subjected to a large impact or vibration, the limiting plate 35 can enhance the stability of the disc structure 3, avoiding affecting the driving safety of the trolley due to violent shaking.
[0050] The limiting groove is a ring structure.
[0051] The limiting plate 35 is a tubular structure.
[0052] Specifically, the limiting groove on the top of the lower heart disc 32 is a ring structure, and the limiting plate 35 matched therewith is a tubular structure. The first end of the limiting plate 35 is fixedly installed at the bottom of the bearing cover plate 34, and the second end is at least partially embedded in the limiting groove. The design of the ring-shaped limiting groove and the tubular limiting plate 35 provides a more reliable limiting function for the heart disc structure 3.
[0053] The inclined area 21 comprises a first inclined section 211 and a second inclined section 212, and the second inclined section 212 is located between the first inclined section 211 and the connecting area 22, and the first inclined section 211 and the second inclined section 212 are inclined downward along the direction from the outside to the inside of the frame 1.
[0054] Specifically, the inclined area 21 comprises a first inclined section 211 and a second inclined section 212, and the first inclined section 211 is located at the outermost side, and the second inclined section 212 is located between the first inclined section 211 and the connecting area 22, and both of them are inclined downward along the direction from the outside to the inside of the frame 1. When the focus tank trolley runs on a curve, the extrusion on the side of the track can be reduced, and the possibility of vehicle derailment can be reduced. The connecting area 22 makes the contact between the wheel 2 and the track more smooth, reduces the wear of the wheel 2 and the track, and prolongs the service life of the two. At the same time, the design of the connecting area 22 ensures the integrity and strength of the structure of the wheel 2, so that the wheel 2 can still maintain a stable running state when bearing a larger pressure.
[0055] The slope of the first inclined section 211 is 1:7.
[0056] The slope of the second inclined section 212 is 1:20.
[0057] A limiting area 23 is further provided on the hub of the wheel 2 and the track contact end, and the limiting area 23 is located on the side of the connecting area 22 away from the inclined area 21.
[0058] Specifically, the limiting area 23 is located on the side of the connecting area 22 away from the inclined area 21 and is arc-shaped and protrudes downward. In the driving process of the focus tank trolley, especially on a curve, the limiting area 23 can prevent the wheel 2 from leaving the track. When the wheel 2 has a tendency to deviate laterally, the limiting area 23 interacts with the edge of the track to limit the excessive movement of the wheel 2, ensuring that the wheel 2 always runs safely on the track, and further improving the safety of the vehicle when driving on a curve.
[0059] The above merely preferred embodiments of the present application are not used to limit the present application, any modification, equivalent replacement and improvement made within the spirit and principle of the present application should be included in the protection scope of the present application. The above is merely the preferred embodiment of the present application, it should be pointed out that, for the ordinary skilled in the art, without departing from the technical principle of the present application, a number of improvements and variations can be made, these improvements and variations should also be considered as the protection scope of the present application.
