[0018] In order to better understand the present invention, the content of the present invention is further explained below in conjunction with embodiments, but the content of the present invention is not limited to the following embodiments.
[0019] Combined with Figure 1-4The utility model is a kind of smelting sand table hoisting column which can prevent the hook from falling off, including a pear-shaped ring hook 4. A plurality of hoisting column bodies 3 which are matched with the pear-shaped ring hook 4 are arranged at intervals along the circumferential direction on the outer circumferential surface of the smelting sand table. The hoisting column body 3 includes a column 3.3 of cylindrical structure. One end of the column 3.3 is fixedly connected to the outer wall of the smelting sand table through a base plate 3.1. The base plate 3.1 is provided to increase the contact area between the column 3.3 and the outer circumferential surface of the smelting sand table, increase the force-bearing area, and improve the hoisting To increase the strength of the column body 3, a baffle 3.4 is provided at the other end of the column 3.3, which protrudes from the outer circumferential surface of the column 3.3. The pear-shaped ring hook 4 can pass through the baffle 3.4 and be mounted on the column 3.3. During operation, the pear-shaped ring hook 4 is placed obliquely and passes through the baffle 3.4 and is mounted on the column 3.3. During the lifting process, the pear-shaped ring hook 4 is always vertically arranged and mounted on the column 3.3. Due to the limiting effect of the baffle 3.4, the pear-shaped ring hook 4 is not easy to fall off, and the pear-shaped ring hook 4 is convenient to be inserted and removed.
[0020] As a design that can be preferred, the smelting sand table lifting column that prevents the hook from falling off is preferably used. The baffle 3.4 is an elliptical structure. The length direction of the baffle 3.4 extends along the circumference of the smelting sand table. During operation, the pear-shaped ring hook 4 can only pass through the baffle 3.4 and be vertically sleeved on the column 3.3 when it is tilted. During the lifting process, the pear-shaped ring hook 4 is always sleeved on the column 3.3 due to the limiting effect of the baffle 3.4. Only when the pear-shaped ring hook 4 is tilted can the baffle 3.4 pass through the inner hole of the pear-shaped ring hook 4, and the pear-shaped ring hook 4 can be removed from the column 3.3, and the pear-shaped ring hook 4 can be conveniently inserted and removed.
[0021] As a design that can be designed first, the smelting sand table lifting column that prevents the hook from falling off is preferably selected, the length L1 of the baffle 3.4 is slightly larger than the axial length L2 of the inner hole of the pear-shaped ring hook 4. When the pear-shaped ring hook 4 is sleeved on the column 3.3, the pear-shaped ring hook 4 is tilted 90 degrees so that the baffle 3.4 can pass through the inner hole of the pear-shaped ring hook 4. The pear-shaped ring hook 4 is vertically sleeved on the column 3.3. When the pear-shaped ring hook 4 is removed from the column 3.3, the pear-shaped ring hook 4 must also be tilted 90 degrees so that the baffle 3.4 can pass through the inner hole of the pear-shaped ring hook 4. The pear-shaped ring hook 4 is removed from the column 3.3 to ensure that when the pear-shaped ring hook 4 is sleeved on the column 3.3, the two are reliably connected, to ensure that when the placement position of the smelting furnace sand table is adjusted, the pear-shaped ring hook 4 will not loosen or decouple, and it is convenient to insert and remove the pear-shaped ring hook 4.
[0022] As a design that can be made first, the smelting sand table lifting column that prevents the hook from falling off is preferably selected, the maximum width r of the baffle 3.4 is slightly smaller than the maximum radius R of the inner hole of the pear-shaped ring hook 4, so that the pear-shaped ring hook 4 can be easily installed and removed, the maximum width r of the baffle 3.4 is equal to the outer diameter of the column 3.3, and the outer diameter of the column 3.3 is slightly smaller than the maximum radius R of the inner hole of the pear-shaped ring hook 4. During the lifting process, the pear-shaped ring hook 4 is subjected to an upward force, and the inner wall of the large diameter end of the pear-shaped ring hook 4 contacts the outer cylindrical surface of the column 3.3. During the non-lifting process, the pear-shaped ring hook 4 falls under the action of gravity, and the inner wall of the small diameter end of the pear-shaped ring hook 4 contacts the outer cylindrical surface of the column 3.3, ensuring that when the pear-shaped ring hook 4 is installed on the column 3.3, the two are reliably connected, ensuring that when the placement position of the smelting furnace sand table is adjusted, the pear-shaped ring hook 4 will not loosen or decouple, and the pear-shaped ring hook 4 can be easily installed and removed.
[0023] As a design that can be preferred, the smelting sand table lifting column that prevents the hook from falling off is preferably provided with a plurality of reinforcing ribs spaced circumferentially between the outer cylindrical surface of one end of the column 3.3 adjacent to the base plate 3.1 and the base plate 3.1, and the reinforcing ribs include first reinforcing ribs 3.2 arranged above and below the column 3.3, and second reinforcing ribs 3.5 arranged on the left and right sides of the column 3.3, the first reinforcing ribs 3.2 and the second reinforcing ribs 3.5 both protrude from the outer cylindrical surface of the column 3.3, and the reinforcement ribs are provided to improve the strength of the column 3.3 on the one hand, and to limit the position of the pear-shaped ring hook 4 on the column 3.3 on the other hand, and the pear-shaped ring hook 4 can only be mounted on the outer cylindrical surface of the column 3.3 where no reinforcing ribs are provided.
[0024] As a possible design, the smelting sand table hoisting column that prevents the hook from falling off is preferably used, and the small-diameter end of the pear-shaped ring hook 4 is connected to the lifting equipment through a sling.
[0025] The working process of the utility model is as follows:
[0026] When the smelting sand table is not in use, Figure 1As shown, the second smelting sand table 2 and the first smelting sand table 1 are stacked up and down. When working, the upper second smelting sand table 2 needs to be lifted, and the smelting furnace barrel is placed on the smelting sand table to form a smelting furnace. Metal heat reduction is carried out in the smelting furnace. After smelting, the overhead crane and the pear-shaped ring hooks 4 are sleeved on the lifting column body 3 on the four sides of the smelting sand table, and the smelting sand table is lifted to an open area to crush and pack the molybdenum iron products. When the pear-shaped ring hooks 4 need to be sleeved on the lifting column body 3, all the pear-shaped ring hooks 4 are tilted 90 degrees in turn to make the baffles 3.4 pass through the inner of the pear-shaped ring hooks 4. The hole is formed by rotating the pear-shaped ring hook 4 by 90 degrees and setting it vertically on the column 3.3; when the pear-shaped ring hook 4 needs to be removed from the column 3.3, all the pear-shaped ring hooks 4 are tilted by 90 degrees in turn, so that the baffle 3.4 passes through the inner hole of the pear-shaped ring hook 4, and the pear-shaped ring hook 4 is removed from the column 3.3. On the one hand, it is ensured that when the pear-shaped ring hook 4 is sleeved on the column 3.3, the two are reliably connected, and on the other hand, it is ensured that when the placement position of the smelting furnace sand table is adjusted, the pear-shaped ring hook 4 will not be loosened or unhooked, and it is convenient to insert and remove the pear-shaped ring hook 4.
[0027] The above description is only an application implementation method of the present utility model, but the protection scope of the present utility model is not limited to this, and the right scope of the present utility model cannot be limited by this. Any equivalent changes made according to the technical solution of the present utility model should be included in the protection scope of the present utility model.
