Description

Technical Field

[0001] The invention relates to the field of aluminum ladle turning racks, in particular to an aluminum ladle turning rack with high safety. Background Art

[0002] The casting process can be divided into three basic parts, namely, casting metal preparation, mold preparation and casting treatment. Casting metal refers to the metal material used for casting in casting production. It is an alloy composed of a metal element as the main component and other metal or non-metal elements. It is usually called casting alloy. There are mainly cast iron, cast steel and cast non-ferrous alloys. Metal smelting is not just a simple melting, but also includes a smelting process, so that the metal poured into the mold meets the expected requirements in terms of temperature, chemical composition and purity. To this end, various inspections and tests for the purpose of quality control should be carried out during the smelting process. The liquid metal can only be poured after reaching various specified indicators. Sometimes, in order to meet higher requirements, the molten metal must be treated outside the furnace after leaving the furnace, such as desulfurization, vacuum degassing, refining outside the furnace, inoculation or metamorphic treatment, etc. Commonly used equipment for smelting metals include cupolas, electric arc furnaces, induction furnaces, resistance furnaces, reverberatory furnaces, etc. The aluminum ladle is a casting equipment, which is used for casting operations in the foundry workshop. It receives the molten iron in front of the furnace and then transports it to the mold by a crane for pouring.

[0003] Due to the presence of bubbles, impurities, impact force of molten aluminum, etc., when the existing aluminum ladle is flipped and poured into the casting mold, the molten aluminum will splash outward, and the molten aluminum has a second slope of 650°C to 700°C, so the high-temperature sputtering of molten aluminum can easily cause safety accidents, and the existing aluminum ladle flipping frame has poor protection, so the safety is low.

Since the piston plate is slidably connected to the inside of the piston cavity, the air inside the piston cavity will pass through the through hole. However, the size of the through hole is limited, which causes the square column to slide downward at a uniform speed.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example 1

[0031] See also Figure 1-2 A high-safety aluminum ladle turning frame comprises a first base 1 and a second base 2 installed at one end of the first base 1, two supporting devices 5 are installed on the upper end of the second base 2, the supporting devices 5 are used to support the aluminum ladle, and both sides of the second base 2 are also slidably connected with protective devices 6, the protective device 6 comprises a first arc plate 62 and a second arc plate 63 slidably connected inside the second base 2, and the first arc plate 62 and the second arc plate 63 are used to wrap the casting mold;

[0032] The supporting device 5 includes a piston cavity 53 arranged on the second base 2, a piston plate 52 is slidably connected inside the piston cavity 53, the piston plate 52 is connected to the second base 2 via a second spring 59, a square column 51 is installed on the upper end of the piston plate 52, the square column 51 is used to support the aluminum water bag, and through holes 54 are arranged on both sides of the piston plate 52, and the through holes 54 penetrate the piston plate 52;

[0033] A bracket 3 is installed at the upper end of the second base 2 , and an electric hoist 4 is installed at one end of the bracket 3 .

[0034] Due to the presence of bubbles, impurities, and impact force of molten aluminum, when the existing aluminum ladle is turned over and poured into the casting mold, the molten aluminum will splash outward, and the molten aluminum has a temperature of 650°C to 700°C on the second slope, so the high-temperature sputtering aluminum is easy to cause safety accidents, and the existing aluminum ladle turning frame has poor protection, so the safety is low;

[0035] according to Figure 1 As shown, the aluminum ladle is placed on the second base 2, the casting mold is placed on the first base 1, and then the aluminum ladle is suspended in the air by driving the hook through the electric hoist 4, and then the motor of the aluminum ladle is started, and the aluminum ladle is driven to rotate by the motor so that the aluminum water inside the aluminum ladle is poured into the casting mold. Figure 2 As shown, the lower end of the inclined aluminum ladle will abut against the square column 51. Since the piston plate 52 is slidably connected to the inside of the piston chamber 53, the air inside the piston chamber 53 will pass through the through hole 54. However, the size of the through hole 54 is limited, which causes the square column 51 to slide downward at a uniform speed. When the aluminum ladle is driven by the motor to rotate rapidly, the downward limit of the square column 51 is used to reduce the risk of the aluminum ladle being quickly dumped out, thereby improving the safety effect.

[0036] The magnet 56 is magnetically attached to the aluminum water bag, so that when the suspended aluminum water bag shakes, the magnet 56 is magnetically limited.

[0037] Example 2

[0038] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-2 The upper end of the square column 51 is slidably connected with a support block 55, and the support block 55 and the square column 51 are connected via a first spring 57. A magnet 56 is installed on the upper end of the support block 55, and the magnet 56 is used for magnetic attraction and adhesion to the aluminum ladle;

[0039] A first gear ring 64 is mounted on the first arc plate 62, a second gear ring 65 is mounted on the second arc plate 63, a motor is mounted inside the second base 2, a gear 61 is connected to the upper end of the motor, and the gear 61 is meshed with the first gear ring 64 and the second gear ring 65;

[0040] A button 58 is also installed on the upper end of the square column 51 . The button 58 is electrically connected to the motor, and the support block 55 is used to abut against the button 58 .

[0041] according to Figure 2As shown, when the aluminum ladle hits the magnet 56, the aluminum ladle will squeeze the support block 55 and slide downward, and the support block 55 presses on the button 58, and the button 58 transmits an electrical signal to the motor at the lower end of the gear 61, so that the motor is energized, and the motor drives the gear 61 to rotate, and the gear 61 meshes with the first gear ring 64 and the second gear ring 65, so that the first gear ring 64 and the second gear ring 65 are driven to move through the gear 61, and the first gear ring 64 and the second gear ring 65 drive the first arc plate 62 and the second arc plate 63 to move, according to Figure 3 As shown, the first arc plate 62 and the second arc plate 63 are staggered so that the first arc plate 62 and the second arc plate 63 slide relative to each other, and then the first arc plate 62 and the second arc plate 63 slide to the limit position, and the casting mold is wrapped by the first arc plate 62 and the second arc plate 63, so as to realize a barrier on the outer surface of the casting mold, thereby blocking the high-temperature aluminum liquid splashing outward from the casting mold.

[0042] Example 3

[0043] This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-3 The first arc plate 62 is slidably connected with a first extension plate 66, and the first extension plate 66 is connected to the first arc plate 62 via a third spring 67;

[0044] A second extending plate 69 is slidably connected to the second arc plate 63 , and the second extending plate 69 is connected to the second arc plate 63 via a fourth spring 68 .

[0045] according to Figure 3 As shown, when the first arc plate 62 and the second arc plate 63 slide out of the second base 2, the first extended plate 66 will be pushed upward by the third spring 67, and the second extended plate 69 will be pushed upward by the fourth spring 68, thereby increasing the protective height of the barrier, thereby further improving the protective effect;

[0046] A first inclined surface 60 is disposed on one side of the first extending plate 66, and a second inclined surface 70 is disposed on one side of the second extending plate 69;

[0047] It should be noted that after the first arc plate 62 and the second arc plate 63 are restored, the first inclined surface 60 and the second inclined surface 70 abut against the second base 2, so that the second base 2 gradually squeezes the first extending plate 66 and the second extending plate 69 to retract and restore.

[0048] Example 4

[0049] This embodiment is an improvement made on the basis of embodiment 3. For details, please refer to Figure 1-5 The upper end of the first base 1 is slidably connected with a cleaning device 7, and the cleaning device 7 includes a scraper 71 slidably connected to the upper end of the first base 1, and the scraper 71 is used to clean aluminum chips on the upper end surface of the first base 1;

[0050] The two sides of the scraper 71 are connected with a slide 72, one end of the slide 72 is connected with a steel cable 73, and the interior of the first base 1 is rotatably connected with a guide wheel 74, and the guide wheel 74 is in contact with the steel cable 73;

[0051] The first base 1 is rotatably connected to two sides with storage wheels 77, one end of the steel cable 73 is connected to the storage wheel 77, and a fifth spring 75 is also installed inside the first base 1, one end of the fifth spring 75 is connected to the outer surface of the steel cable 73;

[0052] A one-way gear 78 is mounted on the upper end of the storage wheel 77. A plurality of single teeth 79 are rotatably connected to the outer surface of the one-way gear 78. A spring piece 80 is connected to one end of the single tooth 79. The spring piece 80 is connected to the one-way gear 78. A stopper 81 is also mounted on the outer surface of the one-way gear 78. The single teeth 79 are used to abut against the stopper 81.

[0053] Racks 8 are installed at the lower ends of the first arc plate 62 and the second arc plate 63;

[0054] One end of the steel cable 73 is also connected to an elastic member 76 .

[0055] When the first arc plate 62 slides out of the second base 2, the rack 8 on the first arc plate 62 will abut against the single tooth 79. Figure 5 As shown, since one end of the single tooth 79 is connected to the one-way gear 78 through the spring sheet 80, the rack 8 will squeeze the single tooth 79 to rotate toward one end, so that when the first arc plate 62 extends out of the second base 2 to protect the casting mold, the one-way gear 78 will not rotate. Then, when the first arc plate 62 is reset, the rack 8 will contact the single tooth 79 again. At this time, a stopper 81 is provided at the other end of the single tooth 79. At this time, the single tooth 79 will contact the stopper 81, so that the single tooth 79 will drive the one-way gear 78 to rotate, and the one-way gear 78 drives the storage wheel 77 to rotate. The storage wheel 77 pulls the steel cable 73 to wrap around the outer surface of the storage wheel 77, and the storage wheel 77 pulls the slide 72 and the scraper 71 to slide, so that after the pouring is completed, the scraper 71 is slidably connected to the first base 1 to clean the outer surface of the first base 1.

[0056] Furthermore, an elastic member 76 is also provided on the steel cable 73, so when the storage wheel 77 rotates, the storage wheel 77 pulls the steel cable 73, and the steel cable 73 pulls the elastic member 76. Since the elastic member 76 is elastic, the elastic member 76 is extended, and the scraper 71 is in contact with the casting mold. Then, when the casting mold leaves the upper end surface of the first base 1, the elastic potential energy of the elastic member 76 quickly pulls the steel cable 73 and the slide 72 to slide, so that the scraper 71 quickly slides on the upper end surface of the first base 1, thereby improving the cleaning effect.

[0057] The elastic member 76 is made of rubber;

[0058] The elastic member 76 is made of a high-elasticity compression spring.

[0060] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention.
