Description

Technical Field

[0001] The invention relates to a sintering machine trolley detection platform and a detection method thereof, belonging to the technical field of auxiliary detection devices for sintering production equipment in the metallurgical industry. Background Art

[0002] The sintering main machine trolley is the carrying equipment for the entire process from the head feeding to the sintering and mineralization. It is the key equipment in the production of sintering machines. Its main function is to form a running rotary chain between the sintering machine head and tail star wheel, and receive the sintering mixture in the upper horizontal section. The mixture ignites the internal fuel under the ignition furnace, and the sintering reaction starts from the surface of the mixture and moves vertically downward. The material undergoes preheating, ignition, sintering, and cooling on the trolley. After turning over, it returns to the head wheel to form a chain cycle to complete the sintering process.

[0003] The trolley consists of a trolley body, wheels, guardrails, sealing devices, side sealing plates, grates, thermal insulation pads, etc. The sintering main trolley plays a vital role in sintering production. Its performance and operating conditions directly affect the output, quality and production efficiency of sintered ore.

[0004] During sintering production, the sintering machine may experience wheel bearing damage, falling off, wheel wear, railing damage, bolt loosening, and trolley frame cracking and deformation. Therefore, the sintering trolley needs to be periodically maintained and trolley parts replaced.

[0005] At present, because a single sintering trolley has four wheels, when a single wheel is damaged, maintenance only involves replacing or repairing the damaged wheel, and inspecting the remaining wheels. After replacing a single wheel, it is impossible to detect whether the four wheels are running on the same plane. In addition, after several years or even more than ten years of use, the trolley frame and bottom beam will deform due to the long-term influence of alternating hot and cold stress. Common problems are cracking, body deformation, and downward deflection of the trolley beam. To ensure the flatness of the four wheels, the deformation of the trolley and the amount of wheel wear need to be detected, but a complete set of detection methods is currently not available. The above problems affect the overall operation of the trolley. In addition, the bottom beam of the trolley frame will cause the bellows partition and the head and tail sealing devices to be scratched, which is prone to equipment failure or accidents.

[0006] Therefore, in order to accurately measure the wear of non-damaged trolley wheels and the deformation of the trolley frame and bottom beam, and at the same time, inspect the repair quality of the trolley after repair, a sintering trolley detection platform is specially invented. Summary of the Invention

[0007] The purpose of the present invention is to provide a sintering machine trolley detection platform and detection method thereof, which can effectively measure the deformation of the trolley frame and the wear of the wheels, check the use status of the trolley, and solve the problems existing in the background technology.

[0008] The technical solution of the present invention is: A sintering machine trolley inspection platform comprises a manually adjustable support device, a hydraulically adjustable support device, a platform frame, a hydraulic cylinder, a slideway, a slide rod, and a measuring scale. The platform frame is a rectangular frame. The manually adjustable support device and the hydraulically adjustable support device are respectively arranged at the four corners of the rectangular frame. The manually adjustable support device and the hydraulically adjustable support device are respectively supported and coordinated with the inspection trolley. A slideway is provided on the platform frame, and the measuring scale is slidably connected to the slideway via a slide rod. The manually adjustable support device comprises a screw, an adjusting nut, a fixing nut and a base, the base is fixed on the platform frame, and the screw is fixed to the base through the adjusting nut and the fixing nut; The hydraulic adjustment support device includes an arc seat, a positioning rod and a support. The support is fixed on the platform frame, the cylinder barrel of the hydraulic cylinder is fixed on the support, the piston rod of the hydraulic cylinder is drive-connected to the arc seat, and the positioning rod is arranged between the arc seat and the support.

[0009] The arc-shaped seat in the hydraulic adjustment support device cooperates with the trolley wheel.

[0010] The arc seat in the hydraulic adjustment support device includes an arc plate, a rib plate and a bottom plate. The curvature of the arc plate matches the trolley wheel, and the arc plate is fixed to the bottom plate through the rib plate.

[0011] The measuring scale is mounted on a slide bar which is slidably connected to a slideway.

[0012] The platform frame is a steel structure rectangular frame which is welded together by cross beams, legs and support beams.

[0013] A sintering machine trolley inspection method adopts a sintering machine trolley inspection platform defined above. During the inspection, the four hydraulic adjustment support devices are first raised synchronously, and the lifting height exceeds the height of the manual adjustment support device; the lifted trolley is slowly placed on the hydraulic adjustment support device, and then the hydraulic adjustment support device is slowly lowered until the trolley is lowered onto the adjustment support device. At this time, the hydraulic adjustment support device no longer plays a supporting role; the manual adjustment support device is synchronously adjusted to ensure that the four manual adjustment support devices are at the same height, and any one or two of the four wheels of the trolley are in contact with the arc seat, and then a feeler gauge is used to measure the gap between the wheel and the arc seat, that is, the wear of the four wheels; finally, a slide bar and a measuring ruler are used to measure the deformation of the two end face frames of the trolley and the trolley bottom beam.

[0014] The synchronously rising height of the four hydraulically adjustable support devices exceeds the height of the manually adjustable support device by 90-110 mm.

[0015] The beneficial effects of the present invention are: the detection platform has a simple structure, convenient detection operation, and accurate measurement. It can effectively measure the deformation, deflection and wheel wear of the trolley body frame, thereby inspecting the use condition of the trolley. At the same time, it can also perform quality acceptance on the repaired trolley. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In this embodiment, refer to the attached Figure 1-8 The trolley inspection platform includes a manually adjustable support device 1, a hydraulically adjustable support device 2, a platform frame 3, a hydraulic cylinder 4, a slide 5, a slide bar 6, a crossbeam 7, a measuring scale 8, a support leg 9, a support beam 10 and a hydraulic system 11, wherein: The platform frame 11 is a rectangular frame made of steel structural materials such as cross beams 7, legs 9 and support beams 10. The manually adjustable support device 1 and the hydraulically adjustable support device 2 are fixed on the four corners of the rectangular frame. The manually adjustable support device 1 and the hydraulically adjustable support device 2 are respectively coordinated with the trolley support.

[0020] The manually adjustable support device 1 comprises a screw 12, an adjusting nut 13, a fixing nut 14 and a base 15. The base 15 is fixed on the platform frame 3. The screw 12 is fixed on the base 15 through the adjusting nut 13 and the fixing nut 14. The hydraulically adjustable support device 2 comprises an arcuate seat 21, a positioning rod 22, and a support 23. The support 23 is fixed to the platform frame 3. The cylinder barrel of the hydraulic cylinder 4 is fixed to the support 23. The piston rod of the hydraulic cylinder 4 is drivingly connected to the arcuate seat 21.

The curvature of the arcuate plate 25 matches the trolley wheel. The arcuate plate 25 is fixed to the base plate 27 via the rib plate 26. To ensure the internal flatness and finish of the arcuate plate 25, turning is required. The main function is to use the arcuate plate 25 as a reference to measure the wear of the trolley wheel with a feeler gauge.

[0021] The upper and lower surfaces of the slide 5 are machined to ensure the accuracy of the upper and lower surfaces, and are installed on both sides of the platform frame 3. At the same time, the base requires machining accuracy to ensure the installation level of the slide 5. The slide rod 6 and the measuring scale 8 adopt a detachable structure.

Adjust the manually adjustable support device 1 to ensure that they are at the same height; slowly place the lifted trolley on the hydraulically adjustable support device 2, and then slowly lower the hydraulically adjustable support device 2 until it lands on the manually adjustable support device 1. At this time, the hydraulically adjustable support device 2 no longer plays a supporting role. Synchronously fine-tune the manual adjustable support device 1 to ensure that the four manually adjustable support devices 1 are at the same height, and adjust them to any one or two of the four wheels of the trolley contact the arc seat 21. Then use a feeler gauge to measure the wear of the four wheels, that is, the gap between the wheel and the arc plate, and calculate the levelness of the trolley. After the inspection and calculation are completed, use the slide rod 6 and the sliding measuring ruler 8 to measure the deformation of the two end face frames of the trolley; the frame and the bottom beam of the trolley. The rest are detected by visual inspection or flaw detection for cracks in the trolley frame.
