[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] like Figures 1 to 7 As shown, a device for quickly changing oil drums in an oil refining production line includes a flipping mechanism 1, a replacement base plate 3, and an oil drum conveying mechanism 5. The flipping mechanism 1 includes a first base 101, a vertical plate 102 perpendicular to the first base 101 is fixedly connected to one side of the upper end of the first base 101, an upper horizontal plate 103 fixedly connected to the vertical plate 102 is provided above the first base 101, and a flipping device 105 is rotatably connected to the first base 101. The flipping device 105 is installed on the first base 101 and can rotate arbitrarily.

[0027] like Figure 6As shown, the flipping device 105 includes a second hydraulic device 1054 rotatably connected to the first base 101. A constraint plate 1055 is fixedly connected to the extended end of the second hydraulic device 1054. Two clamping brackets 1056 are slidably connected to the constraint plate 1055, sliding within the constraint plate 1055 to accurately clamp the oil drum 2. Two connecting rods 1054B are rotatably connected to the outer shell of the second hydraulic device 1054. One end of each connecting rod 1054B is rotatably connected to the clamping bracket 1056. When the extended end of the second hydraulic device 1054 extends or retracts, the movement of the clamping brackets 1056 is controlled by controlling the movement of the connecting rods 1054B. This reduces the need for a power mechanism and saves costs. The other end of the second hydraulic device 1054 passes through the vertical plate 102 and is fixedly connected to the first gear 1054A. A guide rail 1053, fixedly connected to the vertical plate 102, is provided on one side of the first gear 1054A. A slide plate 1052 is slidably connected to the outside of the guide rail 1053. A gear rail 1052A is fixedly connected to the side of the slide plate 1052 near the first gear 1054A. The gear rail 1052A meshes with the first gear 1054A for transmission. A first hydraulic device 1051 is fixedly connected to the upper end of the slide plate 1052 on the vertical plate 102. The extended end of the first hydraulic device 1051 is fixedly connected to the slide plate 1052. The guide rail 1053 is provided to prevent displacement of the gear rail 1052A and the first gear 1054A during meshing transmission. Furthermore, the meshing transmission method of the gear rail 1052A and the first gear 1054A allows for more accurate 180-degree rotation of the second hydraulic device 1054.

[0028] A cleaning device 106 is slidably connected to the bottom of the first base 101 on the side away from the vertical plate 102, such as... Figure 5 As shown, the cleaning device 106 includes a lifting plate 1063. A cleaning pipe 1062 is fixedly connected to the upper part of the lifting plate 1063, and a cleaning nozzle 1061 is fixedly connected to the upper part of the cleaning pipe 1062. The cleaning nozzle 1061 has openings on its upper part and all four sides, which can spray liquid or gas. The lower part of the cleaning pipe is provided with a water inlet pipe and an air inlet pipe. A lead screw 1066 is threadedly connected to one side of the lifting plate 1063. The lead screw 1066 is rotatably connected to the first base 101. A third gear 1067 is fixedly connected to the bottom of the lead screw 1066. A second gear 1065 is meshed and driven to one side of the third gear 1067. A motor 1064 is fixedly connected to one end of the second gear 1065 on the first base 101. The extended end of the motor 1064 is fixedly connected to the second gear 1065. When the motor 1064 rotates, it causes the lead screw 1066 to rotate, thereby raising and lowering the lifting plate 1063 and cleaning the inside of the oil tank 2 with the cleaning nozzle 1061.

[0029] A through groove is provided on the first base 101 at the bottom of the constraint plate 1055. The main function of the through groove is to prevent the constraint plate 1055 from hitting the first base 101 due to insufficient space when it rotates. A first slide rail 6 is fixedly connected to the thickness side of the first base 101 on one side of the through groove, and a first slide block 7 is slidably connected to the first slide rail 6.

[0030] like Figure 3 As shown, the oil drum conveying mechanism 5 includes a second base 501. Two sets of conveyor plates 504 are fixedly connected to the middle of the second base 501. Multiple rollers 505, perpendicular to and rotatably connected to the second base 501, are mounted on the two sets of conveyor plates 504. Multiple rollers 506, horizontally placed and rotatably connected to the second base 501, are mounted above the conveyor plates 504. Conveyor plates 502, fixedly connected to the second base 501, are mounted on the outer sides of the two sets of conveyor plates 504. Multiple electric rollers 503, rotatably connected to the upper half of the conveyor plates 502, are mounted on the upper half of the conveyor plates 502. Rotation of the electric rollers 503 can move the oil drum 2 from one end to the other. A motor 507 is fixedly connected to one side of the upper end of the second base 501. A fourth gear 508 is fixedly connected to the extended end of the motor 507. A second slide rail 8 is fixedly connected to the thickness side of the second base 501 on the same side as the motor 507. A second slide block 9 is slidably connected to the second slide rail 8.

[0031] like Figure 7 As shown, the replacement base plate 3 is located between the first base 101 and the second base 501, and is fixedly connected to the first slide 7 and the second slide 9 respectively. The upper end of the replacement base plate 3 has an L-shaped groove 301, which is hollowed out in the direction parallel to the first slide, facilitating the up-and-down movement of the cleaning nozzle 1061 for cleaning. One opening of the groove 301 faces the center of the second conveyor plate 504, and a toothed plate 302 is fixedly connected to one side of the other opening of the replacement base plate 3. The toothed plate 302 meshes with the fourth gear 508 for transmission. The function of the groove 301 is to hold the oil drum 2 upright through its opening when it enters the groove 301, and to allow the oil drum 2 to be removed from the other opening of the groove 301 when the replacement base plate 3 moves.

[0032] like Figure 2As shown, a conveyor belt 4 is provided between the first base 101 and the second base 501. One end of the conveyor belt 4 is located at the bottom of the replacement base plate 3 and is slidably connected to the replacement base plate 3. A bracket 107 is fixedly connected to the side of the first base 101 near the conveyor belt 4. A telescopic cylinder 108 is fixedly connected above the bracket 107, with the extended end of the telescopic cylinder 108 facing the second base 501. When the telescopic cylinder 108 extends forward, it can push the filled oil drum 2 from the replacement base plate 3 onto the conveyor belt 4. An oil drum 2 is movably connected between the two clamping brackets 1056. A conveying pipe 104 is fixedly connected to the upper horizontal plate 103 directly above the oil drum 2. One end of the conveying pipe 104 passes through the upper horizontal plate 103 and is sealed downwards to a pipe opening 1041.

[0033] Those skilled in the art can use existing technologies they possess, such as installing appropriate mechanical limit switches or photoelectric sensors, to limit the specified positions of each actuator during the following operation process; to achieve automated operation, this utility model can use numerical control technology or PLC to control the actions of each actuator.

[0034] Working process: Oil drum 2 is placed upside down between two sets of conveyor plates 502. The electric rollers 503 on both sides drive oil drum 2 to move towards the flipping mechanism 1, with the opening of oil drum 2 located between the two rollers 505. When the oil drum 2 behind moves the oil drum 2 in front onto the replacement base plate 3, the opening of the oil drum enters the corner of the trough 301. At this time, the second hydraulic device 1054 is activated, which drives the constraint plate 1055 to move forward, and the clamping brackets 1056 on both sides move towards the middle to clamp the oil drum. The motor 1064 starts, driving the second gear 1065 to rotate. The second gear 1065 and the third gear 1067 rotate in coordination, causing the lead screw 1066 to rotate. The lifting plate 1063, which is in coordination with the lead screw 1066, lifts upward, allowing the cleaning nozzle 1061 to enter the oil tank 2 through the oil tank opening. Cleaning liquid is sprayed into the oil tank 2 to clean its interior. After cleaning, the cleaning nozzle 1061 starts to spray high-pressure gas to remove the liquid adhering to the inner wall of the oil tank 2. The liquid flows out along the oil tank opening, keeping the inside of the tank dry. After cleaning, motor 2 507 drives the fourth gear 508 to rotate, so that the fourth gear 508 meshes with the toothed plate 302, driving the replacement base plate 3 to move to one side of the conveyor belt 4, making room for the oil drum 2 to flip. After the replacement base plate 3 has moved, the first hydraulic device 1051 moves downward, and the toothed rail 1052A on one side of the slide plate 1052 drives the first gear 1054A to rotate 180 degrees. The second hydraulic device 1054 connected to the first gear 1054A flips the oil drum 2 180 degrees.

[0035] After the rotation is complete, motor 2 (507) drives the fourth gear (508) to reverse, moving the replacement base plate (3) to the bottom of the oil drum (2), where it rests against the drum. Oil is then filled into the drum (2) via the feed pipe (1041) at the top of the drum (2) through the feed pipe (104). After filling, motor 2 (507) drives the fourth gear (508) to rotate, transporting the oil drum (2) above the conveyor belt (4). At this time, the telescopic cylinder (108) activates, extending the air rod outwards, and the replacement base plate (3) retracts. The oil drum (2) remains stationary because it is held in place by the air rod. Once the replacement base plate (3) is completely removed, the oil drum (2) rests completely above the conveyor belt (4). The filled oil drum (2) is then transported to the next step via the conveyor belt (4).

[0036] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
