Abstract
Description
Technical Field
[0001] The utility model relates to the field of hoisting equipment, and more specifically, to hoisting equipment for producing large-size steel ingot moulds. Background Art
[0002] Ingot molds are special molds used to cast steel ingots, usually made of high-temperature resistant, high-strength materials. They have a specific shape and size design to ensure that the molten steel can solidify and form into an ingot of the desired shape. Ingot molds play a key role in steel production, and their quality and performance directly affect the quality of the ingot, including the surface flatness and internal structure of the ingot. Ingots of different specifications and uses require matching molds to meet the needs of various industrial productions for ingots of different shapes and properties.
[0003] In the production process, steel ingot molds need to be transferred between different workstations or areas to complete a series of operations such as casting. Steel ingot molds are usually large and bulky, and it is difficult to move them directly by manpower. With the help of cranes, they can be moved to the designated location more efficiently and safely.
[0004] A traditional crane has two slings on its lifting part. The ends of the slings are fixed to hooks. The hooks are put on the ears on both sides of the steel ingot mold, and the mold can be supported by the crane for transportation. However, when it is used on a large-size steel nail mold, due to the large width of the large-size steel nail mold and the far distance between the two ears, when the hooks are hung on the ears to transport the large-size steel ingot mold, the inclination angle of the two slings is large, which can easily generate irregular tension on the slings, accelerate the wear and fatigue of the slings, and shorten their service life.
[0005] Therefore, in order to solve the above technical problems, the present application proposes a hoisting device for the production of large-size steel ingot molds. Utility Model Content
[0006] In view of the deficiencies in the prior art, the utility model aims to provide a hoisting device for the production of large-size steel ingot molds.
[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hoisting device for the production of large-size steel ingot molds, including a crane, an adjusting component for adjusting the distance between two slings is installed on the lifting part of the crane, a locking component is provided on the adjusting component to firmly fix the position of the sling, and a hook is fixedly connected to the bottom of the sling, which is connected to the lifting ear on the steel ingot mold through the hook.

[0009] Preferably, the bottom end of the transverse plate is fixedly connected to a guide rail at a position between the bearing seats, and the top end of the moving block is slidably connected to the guide rail via a slider to maintain the linear movement of the moving block.
[0010] Preferably, the locking assembly includes a circular groove seat welded on the end of the connecting rod opposite to the threaded rod, a telescopic rod is fixedly connected to the inner center portion of the circular groove seat, a cylindrical block is fixedly connected to the head of the telescopic rod, a plurality of springs are fixedly connected around the telescopic rod between the cylindrical block and the circular groove seat, a handle is fixedly connected to the head of the cylindrical block, and the handle moves toward the bearing seat under the action of the spring, and the convex structure on the handle is inserted into the concave structure on the bearing seat to fix it by concave-convex matching.
[0011] Preferably, an arc block is fixedly connected to the outer wall of the bearing seat, and a circular groove is provided on the surface of the arc block. A plurality of round rods arranged in a circular array are provided on the back of the handle. After the round rods are inserted into the circular groove, the handle is restricted.
[0012] Preferably, counterweight blocks are installed on both sides of the top of the transverse plate, and the positions of the counterweight blocks can be adjusted. The positions of the counterweight blocks can be adjusted according to the steel ingot mold with asymmetric weights on both sides.

[0014] Compared with the prior art, the utility model has the following beneficial effects:
[0015] 1. The utility model first adjusts the distance between the two slings through the adjustment component, and then firmly fixes the positions of the two slings through the locking component. In this way, when dealing with large-sized steel ingot molds, the distance between the slings can be adjusted to avoid excessive tilting of the slings during transportation, thereby solving the problem in the background technology that when transporting large-sized steel nail molds, the inclination angles of the two slings are large, which easily generates irregular tension on the slings during the transportation of the steel nail molds, accelerates the wear and fatigue of the slings, and shortens their service life;
[0016] 2. The utility model adjusts the positions of the two slings by rotating the threaded rod with the handle. The handle can be rotated by simply pulling the handle toward the direction of the principle bearing seat. When the handle is released, the handle will automatically reset due to the action of the spring, so that the cylinder on it is inserted into the circular groove to restrict the handle and the threaded rod, thereby locking the positions of the two slings. The operation steps are simple.
[0017] 3. The utility model can adjust the position of the counterweight block according to the steel ingot mold with asymmetric weight on both sides, perform reasonable weight distribution, and improve the stability of transportation. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] like Figure 1-6 As shown, the utility model provides a hoisting device for the production of large-size steel ingot molds, including a crane 1, an adjusting component 3 for adjusting the distance between two slings 4 is installed on the lifting part of the crane 1, a locking component 5 is arranged on the adjusting component 3 to firmly fix the position of the sling 4, a hook 2 is fixedly connected to the bottom of the sling 4, and the hook 2 is connected to the lifting ear on the steel ingot mold, that is, the distance between the two slings 4 is first adjusted by the adjusting component 3, and then the position of the two slings 4 is firmly fixed by the locking component 5, so that when dealing with large-size steel ingot molds, the distance between the slings 4 can be adjusted to avoid excessive tilting of the slings 4 during transportation.
[0031] The adjusting assembly 3 includes a transverse plate 301 fixed on the lifting part of the crane 1, and bearing seats 302 are fixedly connected to both sides of the bottom end of the transverse plate 301, and support bearings 303 are installed inside the bearing seats 302, and connecting rods 304 are fixedly connected in the inner ring of the support bearings 303, and threaded rods 305 are fixedly connected between the connecting rods 304, and the threads on both sides of the threaded rods 305 are opposite and symmetrical in the middle, and moving blocks 306 are threadedly connected to both sides of the threaded rods 305, and the head of the sling 4 is fixed to the moving block 306, and the bottom end of the transverse plate 301 is fixedly connected to the guide rail 307 at the position between the bearing seats 302, and the top of the moving block 306 is slidably connected to the guide rail 307 through a slider 308, and the locking assembly 5 includes a circular groove seat 501 welded on the opposite end of the connecting rod 304 and the threaded rod 305. A telescopic rod 502 is fixedly connected to the inner center of the circular groove seat 501, and a cylindrical block 503 is fixedly connected to the head of the telescopic rod 502. A plurality of springs 504 are fixedly connected around the telescopic rod 502 between the cylindrical block 503 and the circular groove seat 501, and a handle 505 is fixedly connected to the head of the cylindrical block 503. The handle 505 moves toward the direction of the transverse bearing seat 302 under the action of the spring 504, and the convex structure on the handle is inserted into the concave structure on the bearing seat 302 to fix it in a concave-convex matching manner. An arc block 506 is fixedly connected to the outer wall of the bearing seat 302, and a circular groove 507 is provided on the surface of the arc block 506. A plurality of round rods 508 arranged in a circular array are provided on the back of the handle 505. After the round rods 508 are inserted into the circular groove 507, the handle 505 is restricted.
[0032] When in use, the handle 505 is pulled to move in the direction away from the circular groove seat 501, and the handle 505 drives the cylindrical block 503 to move, and the telescopic rod 502 is extended accordingly to maintain the linear movement of the handle 505, and at the same time, the spring 504 is stretched to pull the cylindrical block 503 on the handle 505 out of the circular groove 507 of the arc block 506, and then the handle 505 can be freely rotated. The handle 505 drives the rotation of the connecting rod 304 through the telescopic rod 502, and the connecting rod 304 drives the rotation of the threaded rod 305. At the same time, the connecting rod 304 also drives the rotation of the inner ring of the supporting bearing 303, and the inner ring of the supporting bearing 303 rotates along its outer ring to support the threaded rod 305 and the connecting rod 304. The threaded rod 305 is rotated clockwise or counterclockwise by the handle 505, so that the moving block 306 can move to the middle part or to both sides at the same time, and the moving block 306 drives the movement of the slider 308, and the slider 308 slides along the guide rail 307 to maintain The movable block 306 is held to move back and forth in a straight line, thereby adjusting the distance between the two slings 4 to cope with large-sized steel ingot molds or normal molds (the distance between the slings 4 on both sides of the normal steel ingot mold is moderate, and the large-sized steel ingot mold requires a larger distance between the two slings 4, which is adjusted as needed. If the distance between the two slings 4 is not compatible with the mold, it will affect the stability of transportation). The adaptability is enhanced, and the tilt angle of the sling 4 is prevented from being too large when transporting large-sized steel ingot molds. After adjusting the distance, the handle 505 is released, and the spring 504 uses its elasticity to reset the handle 505, so that the round rod 508 on the handle 505 is inserted into the circular groove 507 to limit the handle 505, thereby limiting the rotation of the threaded rod 305, thereby locking the positions of the two slings 4, so that the two are firmly fixed. Finally, the hook 2 at the bottom of the sling 4 can be connected to the lifting ear on the mold, and the mold can be lifted and transported by the crane 1.
[0033] like Figure 3 , Figure 5 and Figure 6 As shown, further, counterweight blocks 6 are installed on both sides of the top of the cross plate 301, and the position of the counterweight blocks 6 can be adjusted, so that the position of the counterweight blocks 6 can be adjusted according to the asymmetric weight of the steel ingot mold on both sides, so as to perform reasonable weight balancing and improve the stability of transportation. The following is the specific structure of the adjustment: concave long strips 7 are fixedly connected to both sides of the top of the cross plate 301, and the inner block 8 is slidably connected to the inside of the concave long strips 7. The top of the inner block 8 is fixed to the counterweight block 6, and the side end of the inner block 8 is provided with a screw hole 9, and the surface of the concave long strips 7 is provided with a plurality of through holes 10 arranged in a horizontal array.
[0034] That is, the counterweight block 6 is pushed to move back and forth. When it moves to the appropriate position, a large screw is passed through the through hole 10 at the corresponding position on the concave long plate 7 and then rotated clockwise to be installed into the screw hole 9 to fix the position of the counterweight block 6. The position of the counterweight block 6 can be adjusted according to the asymmetric weight of the steel ingot mold on both sides to perform reasonable weight balancing.
