Description

Technical Field

[0001] This utility model relates to a trolley tilting device for a tilting trolley. This utility model also relates to a sintering equipment or a granulation equipment. Background Technology

[0002] In sintering and granulation equipment, the material to be processed (e.g., iron ore or zinc ore) is fed onto trolleys. The trolleys move through a processing zone where the material undergoes heat treatment, such as drying, sintering, and cooling. The equipment may include a sintering machine or granulator with lifting rollers, lowering rollers, and guide rails arranged around them. The trolleys are conveyed on the guide rails in a circular chain. The trolley chain moves along the top of the guide rails through the processing zone. At the top end of the lowering rollers, the heat-treated material is discharged from the trolley by gravity, and then the trolley tilts up and down, the empty trolley returning along the bottom of the guide rails to the lifting rollers.

[0003] Because the trolleys and their components are subjected to high thermal and mechanical loads during production, they must be overhauled after a certain degree of wear or damage. Trolleys are typically removed from the bottom of the sintering or pelletizing machine in an upside-down position. After removal, the trolley must be tilted to its operating position for proper maintenance. Due to the weight of the trolleys, operators must manually tilt them using auxiliary devices such as cranes, overhead cranes, or forklifts, which can be unsafe, time-consuming, and potentially damaging. When lifting and tilting trolleys with forklifts, the forklift may become wobbly and unstable if the load center of gravity is incorrect. Furthermore, the work area around the forklift is unprotected, potentially leading to dangerous situations.

[0004] Similar problems exist in workshops for sintering and granulation equipment when it is necessary to rotate the trolley. Summary of the Invention

[0035] The trolley tilting device 1 may also include a pair of trolley tracks 24 along which the trolley 4 can move to and / or be removed from the rotating frame 3. Since the trolleys do not have their own actuators, the trolley tilting device 1 may be provided with a trolley moving device 23, which is configured to move the trolley 4 along the trolley tracks 24 to and / or away from the rotating frame 3.

[0036] The trolley moving device 23 may include at least one track 14 (typically two or more tracks 14) and a moving mechanism 15 movable in the opposite direction along the tracks 14. The moving mechanism 15 is configured to engage with the trolley 4 for moving the trolley 4 along the trolley tracks 24. The tracks (or tracks) 14 are arranged between the trolley tracks 24, typically at a lower height than the trolley tracks 24. The trolley tracks 24 are parallel to the tracks 14.

[0037] The moving mechanism 15 may include at least one or two arms 16 configured to engage with a trolley 4 to be moved. The arms 16 are configured to engage with the central portion and / or the front and / or rear surfaces of the trolley 4. As the moving mechanism 15 moves along the track 14, the arms 16 may retract and / or rotate to a position in which the arms 16 are arranged to allow the trolley 4 to pass over the trolley track 24.

[0040] The trolley moving device 23 may further include two sprockets 19 and an annular chain 20 arranged to connect to each track 14. The sprockets 19 are arranged to be spaced apart from each other at a distance along the direction of movement of the moving mechanism 15 and / or along the longitudinal direction of the track 14. The track 14 may be arranged between the sprockets 19. The annular chain 20 is arranged around the sprockets 19. The annular chain 20 has an upper portion 20.1 and a lower portion 20.2.

The drive device 18 is arranged to rotate one of the sprockets 19. The other sprocket 19 is free to rotate. When the sprocket 19 rotates, the annular chain 20 rotates around the sprocket 19, thereby moving the moving mechanism 15 along the track 14.

[0041] In the case where the trolley moving device 23 includes two or more parallel rails 14, the parallel sprocket 19 can be connected to the connecting shaft 21, and the drive device 18 is configured to rotate one of the connecting shafts 21.

[0042] The trolley moving device 23 may include: a position sensor that monitors the position of the trolley 4 on the trolley track 24 and / or the position of the moving mechanism 15 on the track 14; and a control unit configured to receive data from the position sensor and operate the drive device 18 and / or the arm 16 based on the data.

[0043] The aforementioned trolley tilting device 1 operates as follows: Trolley 4 moves along trolley track 24 toward trolley tilting device 1. Trolley 4 is received by receiving mechanism 6 of rotating frame 3. Wheels 8 of trolley 4 are locked by locking mechanism 12. The locking component of locking mechanism 12 moves between the wheels 8 on both sides of trolley 4 and engages with the wheels 8. Then, rotating frame 3 and trolley 3 rotate about rotation axis 5. After rotating frame 3 and trolley 4, locking mechanism 12 is released. Then, trolley 4 is removed from rotating frame 3. Trolley 4 moves away from trolley tilting device 1 along trolley track 24.

[0044] like Figure 3As shown, the trolley tilting device 1 can be used in a sintering or granulation apparatus 22. The sintering / granulation apparatus 22 may include a sintering machine or granulator 25 having a removal point 26 through which the trolley 4 is removed from the sintering machine / granulator 25 in an upside-down position, and the trolley tilting device 1 is arranged to connect to the removal point 26. The sintering machine / granulator 25 may include a lifting wheel 27, a lowering wheel 28, and a guide rail 29 arranged around the lifting wheel 27 and the lowering wheel 28. The trolley 4 is arranged to be conveyed on the guide rail 29 in a circular chain, and the removal point 26 is arranged in the lower portion of the sintering machine / granulator 25, in which the trolley 4 is conveyed in an upside-down position. The sintering machine / granulator 25 also includes a feed point through which the trolley is inserted into the sintering machine / granulator 25.

[0045] In the case where the trolley tilting device 1 includes a trolley moving device 23, the trolley moving device 23 can be configured to move the trolley 4 from the removal point 26 to the rotating frame 3.

[0046] The trolley tilting device 1 can also be used in other applications where the trolley 4 needs to be tilted, such as in the workshop of sintering equipment or granulation equipment 22.
