Description

Technical Field

[0001] This utility model relates to the field of deep well casting aluminum rod production technology, and in particular to a device for cleaning deep well aluminum slag from alloy rods. Background Technology

[0002] Aluminum alloy rods are a type of aluminum product. They are produced through processes such as batching, refining, and filtration, followed by cooling and casting into alloy rods of various specifications using a deep-well casting system. Because casting takes place in a 13-meter-deep well, some molten aluminum is rapidly cooled and forms irregular lumps that fall into the deep well through gaps in the casting system. Cleaning the molds causes aluminum slag adhering to the surface, which easily falls through the gaps in the ingot head. Over time, as the aluminum slag accumulates to a certain height, it occupies too much space in the well, preventing the crystallizer base from descending properly and thus affecting the length of the aluminum rods. Therefore, to ensure the normal casting of the alloy rods, the aluminum slag in the well must be removed.

[0003] The traditional method for cleaning aluminum slag is to first pump out all the water from the well, then send someone down to the bottom of the well to put the aluminum slag into bags, and then lift the aluminum slag out of the well one by one. The above aluminum slag cleaning process is done manually and requires the cooperation of many people, but the work efficiency is still very low and there are great safety hazards, mainly in the following aspects: (1) The well is 12 meters deep and the pumping time is long, which seriously delays normal production. (2) The hot and oxygen-deficient working space is small, and the workers will suffer from oxygen deficiency, suffocation and safety accidents if they are cleaned in the well for a long time. (3) The bottom slag has a large water content and is difficult to clean, and the labor intensity of the workers is high and they are prone to exhaustion when cleaning manually. (4) When lifting the aluminum slag out of the well, aluminum slag will fall and hit the workers in the well. (5) The workers need to be hoisted down and up the well, which poses a safety hazard of falling from a height.

[0004] Currently, hydraulic cleaning devices are also used to remove aluminum slag from deep wells. During operation, the entire device is first lowered into the well. Then, the hydraulic pump is activated, and hydraulic cylinders control the opening and closing of two buckets. As the buckets close, the aluminum slag is collected inside. However, this method involves the entire hydraulic system being submerged in water, which can lead to water pollution from leaks in hydraulic components and corrosion of the hydraulic cylinders. Utility Model Content

[0005] The purpose of this invention is to provide a device for cleaning aluminum slag in deep wells using alloy rods, thereby solving the technical problems mentioned in the background section.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This utility model discloses a device for cleaning aluminum slag in deep wells using alloy rods. It includes an upper support beam with two sets of struts symmetrically hinged on both sides. The other ends of the two struts on the same side are respectively hinged to the outer ends of a grab bucket. The two grab buckets are symmetrically hinged to the lower ends of a lower support beam on opposite sides. A vertical sliding rod is fixedly installed on the upper part of the lower support beam and slides in cooperation with the middle of the upper support beam. The sliding rod is connected to a drive mechanism for driving its up-and-down movement.

[0008] Furthermore, the driving mechanism includes a sliding block slidably sleeved on the slide rod, with both sides of the sliding block connected to the crane hook via lifting wire ropes, and a locking mechanism for fixing the sliding block and the slide rod to the two are provided.

[0009] Furthermore, pulleys are rotatably provided on both sides of the sliding block, the lower end of the lifting wire rope is wound around the pulleys, and the upper part of the lifting wire rope extends to the upper end of the sliding rod and forms a wire rope lifting ring for connection with the hook of the crane.

[0010] Furthermore, the locking mechanism includes a locking block hinged to the sliding block, one end of the locking block extending into the interior of the sliding block, and the slide rod having a groove at a position corresponding to the locking block. The upper end of the groove is a planar structure, and the lower end of the groove is a downwardly inclined slope structure. The end of the locking block located outside the sliding block is fixedly connected to the bottom of the upper support beam by a spring.

[0011] Furthermore, the slide bar is fixedly provided with a limiting boss at the position above the upper support beam, and each limiting boss has a through hole for the lifting wire rope to pass through.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0013] When cleaning aluminum slag inside deep wells using this invention, it is not necessary to pump out the water from the well. The device can be used simply by lifting it with an overhead crane, and the entire process can be completed by a single crane operator without the need for additional personnel. This invention not only eliminates various safety hazards and reduces the labor intensity of manual well cleaning, but also greatly improves overall work efficiency. Attached Figure Description

[0020] like Figures 1-4 As shown, a device for cleaning aluminum slag in deep wells using alloy rods includes an upper support beam 1. Two sets of support rods 2 are symmetrically hinged on both sides of the upper support beam 1. The other ends of the two support rods 2 on the same side are respectively hinged to the outer ends of a grab bucket 3. The two grab buckets 3 are symmetrically hinged to the lower ends of a lower support beam 4 on opposite sides. A vertical sliding rod 5 is fixedly installed on the upper part of the lower support beam 4 and slides in cooperation with the middle part of the upper support beam 1. The sliding rod 5 is connected to a drive mechanism for driving its up and down movement.

[0021] In this embodiment, the driving mechanism includes a sliding block 7 slidably sleeved on the slide rod 5. The sliding block 7 is connected to the crane hook via a lifting wire rope 8. A locking mechanism is provided between the sliding block 7 and the slide rod 5 to fix the two together.

[0022] The locking mechanism includes a locking block 9 hinged to the sliding block 7. One end of the locking block 9 extends into the interior of the sliding block 7. The slide rod 5 has a groove 10 at a position corresponding to the locking block 9. The upper end of the groove 10 is a planar structure, and the lower end of the groove 10 is a downwardly inclined slope structure. The end of the locking block 9 located outside the sliding block 7 is fixedly connected to the bottom of the upper support beam 1 by a spring 11.

[0023] The sliding block 7 is provided with pulleys 12 on both sides, the lower end of the lifting wire rope 8 is wound around the pulley 12, and the upper part of the lifting wire rope 8 extends to the upper end of the sliding rod 2 and forms a wire rope shackle 13 for connecting with the hook of the crane.

[0024] In addition, the slide bar 5 is fixedly provided with a limiting boss 6 at the position above the upper support beam 1, and each limiting boss 6 is provided with a through hole for the lifting wire rope 8 to pass through.

[0025] The working principle of this utility model is as follows:

[0026] First, the crane lifts the entire device using a wire rope hoist, placing the grab bucket on the material to be grabbed. Then, the crane lowers, causing the sliding block to descend along the slide rod. When the locking block on the sliding block reaches the groove position on the slide rod, the locking block is engaged in the groove due to the spring tension, thus fixing the sliding block to the slide rod.

[0027] The crane lifts the hoisting wire rope again, causing the entire sliding block to move upward. Because the sliding block and the sliding rod are fixedly engaged through the locking block, the sliding rod and the lower support beam move upward as the sliding block moves upward. During the upward movement of the lower support beam, a lever arm rotates due to the hinged connection with the grab bucket, causing the two grab buckets to move relative to each other to complete the material grabbing work. When the grab buckets are in a closed loop, the sliding block moves to the high position.

[0028] When unloading is about to begin, the hook releases the wire rope downwards. At this time, the bottom of the grab bucket contacts the support surface first, the sliding block descends, and the locking block slides out from the bottom of the groove due to the downward force of the sliding block. At this time, the spring is not under force, and the locking block is lifted up by gravity. During the descent, the lower support beam moves downwards, forming an opposite force arm rotation with the two grab buckets, causing the two grab buckets to move in opposite directions to complete the grab bucket opening and unloading.

[0029] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
