Description

Technical Field

[0001] This utility model relates to the field of coal leveling technology, and in particular to a fully automatic coal leveling machine for coal loading cars in coking equipment. Background Technology

[0002] Currently, major coking plants are implementing smokeless coal charging. After the coal bunker of a tamping-type coke oven is tamped, loose coal with varying heights is generated at the top of the bunker. If left untreated, this loose coal will produce a large amount of dense smoke when it encounters high temperatures in the furnace, wasting raw materials and impacting the environment. The dense smoke contains a large amount of large particles, which can cause blockages in the gas collecting pipe after entering, increasing equipment maintenance costs. Moreover, this loose coal located at the coal seam will form incomplete coke and waste coke after refining, directly affecting the yield and quality of coke and the economic benefits of coking plants. Therefore, using a coal leveler to level and compact the loose coal on top of the tamped coal cake has become an inevitable choice for all tamping coking plants.

[0003] Traditional coal levelers use a unidirectional drag wheel to press coal, which can easily create dead zones and is inefficient. Utility Model Content

The output end of the hydraulic cylinder is fixedly connected to a movable frame. Pins are symmetrically fixedly connected to the movable frame. An L-shaped movable wall is rotatably connected to the pins. A coal pressing wheel is rotatably connected to one end of each movable wall. A T-shaped rod is rotatably connected to the movable wall. The upper end of the T-shaped rod is slidably connected to one end of the movable frame.

[0008] Preferably, a second hydraulic cylinder is fixedly connected to the support frame, and a maintenance platform is fixedly connected to the output end of the second hydraulic cylinder.

[0011] Preferably, the drive assembly includes a speed reducer, a drive sprocket is mounted on the output end of the speed reducer, and a variable frequency drive is mounted on one side of the speed reducer.

[0012] Compared with existing technologies, the beneficial effects of this utility model are:

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0022] Reference Figure 1 A fully automatic coal leveling machine for a coking equipment coal loading car includes a support frame 1 and a track 15 laid on the ground. A coal pressing device is installed on the support frame 1, and a traveling mechanism is installed on the track 15. The coal pressing device includes a hydraulic cylinder 7 installed on the support frame 1. The hydraulic cylinder 7 includes a cylinder body and a telescopic rod. This is prior art, and its working principle is not described in detail. The output end of the hydraulic cylinder 7 is located behind the telescopic rod. A movable frame 6 is fixedly connected to the output end of the hydraulic cylinder 7. Pins 5 are symmetrically fixedly connected to the movable frame 6. L-shaped movable walls 4 are rotatably connected to the pins 5. A coal pressing wheel 2 is rotatably connected to one end of each movable wall 4. A T-shaped rod 3 is rotatably connected to the movable wall 4, and the upper end of the T-shaped rod 3 is slidably connected to... At one end of the movable frame 6, a spring 8 is sleeved on the T-shaped rod 3, and the upper and lower ends of the spring 8 are fixedly connected to the movable frame 6 and the T-shaped rod 3 respectively. When compacting the coal, the hydraulic cylinder 7 is controlled to shorten upward. Since the pin 5 and the movable wall 4 are rotatably connected, when the movable frame 6 moves upward under the action of the hydraulic cylinder 7, one end of the movable wall 4 with the coal pressing wheel 2 will rotate downward, and the other end of the movable wall 4 will rotate upward. The two movable walls 4 form a figure-eight shape. Compared with the mechanism of unidirectional dragging of the coal pressing wheel, the figure-eight setting effectively solves the problem of dead corners in coal leveling, ensures that the coal cake in the coal bunker is effectively compacted, improves work efficiency, reduces labor, and ensures safe production.

[0023] refer to Figure 1 A protective cover is installed on the support frame 1. An installation plate 11 is fixedly connected to the front end of the protective cover. A rotating arm 10 is rotatably connected to the installation plate 11. A scraper 9 is fixedly connected to the rotating arm 10. When the scraper 9 is rotated and reaches a suitable angle, it is fixed between the rotating arm 10 and the installation plate 11 by bolts. Then, the coal in front is scraped flat to facilitate the compaction of the coal pressing wheel 2 behind.

[0024] refer to Figure 2A hydraulic cylinder 22 is fixedly connected to the support frame 1. The output end of the hydraulic cylinder 22 is fixedly connected to the maintenance platform 14. The distance between the maintenance platform 14 and the support frame 1 is controlled by controlling the extension and retraction of the hydraulic cylinder 22, which can adapt to the installation of coal loading cars at different distances.

[0025] refer to Figure 1 The front end of the inspection platform 14 is symmetrically fixedly connected with right-angle plates 13. A track cleaning plate 12 is fixedly connected between the two right-angle plates 13. Bolts are provided on the track cleaning plate 12, and long slots are provided on the right-angle plates 13. Bolts pass through the long slots and are installed on the track cleaning plate 12. The height of the track cleaning plate 12 on the right-angle plates 13 is adjusted according to the height of the track 15. After adjustment, it is fixed with bolts to clean obstacles in front of the track.

[0026] refer to Figure 3 The traveling mechanism is mounted on the inspection platform 14. The traveling mechanism includes multiple traveling wheels 18 that move on the track 15. Each traveling wheel 18 includes front wheels and rear wheels. The traveling wheels 18 are interconnected by drive shafts and couplings 20. Each drive shaft is equipped with a driven sprocket 19. Two driven sprockets 19 are connected by a chain. Drive shafts are installed between the two front wheels and the two rear wheels. Two drive shafts are connected by couplings 20. One of the drive shafts is equipped with a second drive sprocket 21. The second drive sprocket 21 is connected to a first drive sprocket 16 by a second chain. A drive assembly is provided on one side of the first drive sprocket 16. The first and second chains are not shown. When the drive assembly provides driving force to drive the first drive sprocket 16 to rotate, the second drive sprocket 21 will rotate through the second chain, which will then drive the drive shaft to rotate, and then drive the rear wheels to rotate. At the same time, the driven sprockets 19 and the first chain will drive the front wheels to rotate. In this way, the four traveling wheels 18 move forward and backward on the track 15.

[0027] The drive assembly includes a reducer, a drive sprocket 16 is installed at the output end of the reducer, and a variable frequency drive 17 is installed on one side of the reducer. A 4KW motor hardened gear reducer is controlled by a 5.5KW variable frequency drive 17, which connects to four traveling wheels 18, so that the load capacity of the whole machine reaches five tons and the lateral drag load reaches more than four tons.

[0028] The control of the aforementioned electronic components, such as speed reducers, variable frequency drives, and hydraulic cylinders, is all achieved through remote automatic control using PLCs, enabling the equipment to meet the technical requirements of completing coal leveling operations with a single click, and making on-site operation more convenient.

[0029] The above description is only a preferred embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and practical concept of this utility model, should be included within the scope of protection of this utility model.
