Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of industrial automation equipment, and particularly relates to an automatic flipping device adaptable to multiple mixing pots. Background Technique
[0002] At present, the mainstream charging process of composite solid propellants adopts vertical / horizontal vacuum mixing process. After the slurry mixing is completed, a large amount of propellant slurry remains on the mixing pot. The slurry contains energetic components such as oxidants and explosives, and has a high sensitivity. Under the stimulation of external factors such as impact, friction, and static electricity, it is easy to cause accidents such as combustion and even explosion. When cleaning the mixing pot, personnel need to enter the mixing pot for manual scraping and waste transfer. Once an accident occurs, it is difficult for personnel to escape, which is a high-risk process link prone to safety accidents and the danger is prominent. Therefore, it is necessary to use automatic equipment to replace manual operations, that is, use mechanical equipment to flip and adjust the position of the mixing pot and then use a robotic arm for scraping.
[0003] Due to the existence of multiple different types of mixing pots, each mixing pot requires a corresponding and adaptable flipping frame. However, using the corresponding mixing pot flipping frame for on-site cleaning will affect the mixing rhythm of the mixing workshop, restrict the mixing ability, and there are problems such as low mixing efficiency and scattered cleaning points for the mixing pot flipping, which has become one of the bottleneck problems restricting the improvement of propellant charging production capacity and the upgrade of automatic safety process technology.

[0027] To make the objectives, content, and advantages of the present utility model clearer, the following further describes in detail the specific implementation manner of the present utility model with reference to the accompanying drawings and embodiments.
[0028] The automatic flipping device for multiple types of mixing pots in this embodiment includes a frame 1, a lifting mechanism 2, a flipping mechanism 3, a pot ear fixing part 4, and a lower support arm 5.
[0029] I. Frame 1: It includes a base 1-1, a frame 1-2, etc. The base 1-1 is closely fitted with the ground foundation and grouted with cement; the frame 1-2 is firmly welded with stainless steel material. The total weight of the frame 1 is 30 tons, which can meet the lifting and flipping requirements of mixing pots with weights ranging from 3 tons to 7 tons.
[0030] II. Lifting mechanism 2: It includes a lifting mechanism explosion-proof motor 2-1, a lead screw 2-2, etc. The lifting mechanism 2 mainly uses the lifting mechanism explosion-proof motor 2-1 as the power. The lifting mechanism explosion-proof motor 2-1 is placed below the frame 1 and cooperates with the lead screw 2-2 as the transmission component to achieve lifting within a certain height range. The lifting heights of multiple types of mixing pots are the same to ensure that the mixing pot is coaxial with the automatic cleaning robotic arm after flipping. The lifting mechanism explosion-proof motor 2-1 is equipped with a built-in brake device, and the lead screw 2-2 has self-locking ability, which can effectively ensure the safety during the lifting process of the mixing pot.
[0031] III. Flipping mechanism 3: It includes a flipping mechanism explosion-proof motor 3-1, a speed reducer 3-2, etc. The flipping mechanism mainly uses the flipping mechanism explosion-proof motor 3-1 as the power and cooperates with the speed reducer 3-2 as the transmission component to achieve flipping of torque within a certain range. The flipping angles of multiple types of mixing pots are the same to ensure that the mixing pot is coaxial with the cleaning robotic arm. The flipping mechanism explosion-proof motor 3-1 is equipped with a built-in brake device, and the speed reducer 3-2 has self-locking ability, which can effectively ensure the safety during the flipping process of the mixing pot.
[0032] IV. Pot ear fixing part 4: It includes a fixing part welding plate 4-1, positioning pins 4-2, claw 4-3, clamping driving cylinder 4-4, etc. The two positioning pins 4-2 are locked and fixed by a triangular handle for positioning, and are lifted by a double-hook sling during hoisting. Each claw 4-3 is driven to move by a clamping driving cylinder 4-4. The claw 4-3 has a T-shaped block structure and can slide back and forth in the T-shaped groove. When the 4 clamping driving cylinders 4-4 act simultaneously, they can clamp the pot ears at the same time. The force for fixing the pot ears is the strength stress of the material of the claw 4-3. The clamping driving cylinder 4-4 is selected as an AirTAC cylinder with a brake. It can hold the brake when the air is cut off, and the braking torque can reach 2200 N, ensuring that the claw 4-3 will not affect its fixing effect whether the air is cut off or not when fixing the pot ears.
[0033] V. Lower support arm 5: It includes a support frame 5-1, a lifting handwheel 5-2, etc. The support frame 5-1 can be compatible with the pot racks at the bottom of various mixing pots. The lifting handwheel 5-2 can finely adjust the height of the support frame 5-1 to ensure the stability of the support for the pot rack at the bottom of the mixing pot. The lower support arm 5 can cooperate with the pot ear fixing part 4 to position and fasten the mixing pot both vertically and horizontally, improving the safety during the lifting and flipping processes.
[0034] The working process of the automatic flipping device for various mixing pots is as follows:
[0035] Manually lift the pot ear fixing part 4 above the flipping device frame 1. After alignment, manually install the triangular handle screws until they are locked. Insert the air circuit plug into the corresponding female plug to complete the installation of the pot ear fixing part 4. Receive the transferred mixing pot. Manually remove the pot lid and place it in the pot lid storage area. Then hoist the mixing pot into the card slot of the pot ear fixing part 4. Manually turn the pneumatic plug pin knob to the "extended" position. The 4 positioning pins 4-2 (2 on each side, left and right) are positioned into the guide post holes of the mixing pot. The clamping driving cylinder 4-4 drives the claw 4-3 to extend, making the pot ears of the mixing pot firmly fixed. Press the "up" button of the lower support arm 5. The support frame 5-1 rises to approach and firmly support the channel steel on the mixing pot. Manually rotate the lifting handwheel 5-2 for fine adjustment to ensure that the mixing pot is firmly supported. After that, the operator evacuates the workshop and enters the control room to prepare for remote operation. In the control room, adjust the knob to automatic and press the button. The lifting mechanism 2 drives the mixing pot to rise, and the flipping mechanism 3 drives the mixing pot to flip 110 degrees. After the lifting mechanism 2 automatically adjusts the height to be coaxial with the robotic arm of the cleaning machine, the cleaning operation of the mixing pot can be carried out.
[0036] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and deformations can still be made, and these improvements and deformations should also be regarded as the protection scope of the present invention.
