Description

Technical Field

[0001] This utility model belongs to the field of hoisting equipment technology, specifically relating to an auxiliary device for hoisting a gyratory breaking cone. Background Technology

[0002] Gyratory crushing cones crush materials through gyratory motion. During operation, they typically require a crane to lift them to the designated position and install them. Current technology necessitates the use of a lifting beam or balance frame when hoisting the gyratory crusher's moving cone to avoid single-point handling. However, the installation and dismantling of the lifting beam or balance frame are complex, requiring significant manpower and time. Furthermore, during hoisting, asymmetrical internal structures of the moving cone or incorrect lifting point selection can lead to tilting, rotation, or even collisions with nearby buildings, causing irreversible damage to the gyratory crusher's moving cone. The oscillation of the moving cone during suspension can also cause friction with the slings or lifting beam, damaging its surface and affecting its service life. Utility Model Content

[0003] This utility model provides an auxiliary device for hoisting a gyratory crushing cone. It is easy to install and disassemble, and can prevent the gyratory crushing cone from swinging and colliding during the hoisting process, thereby reducing damage to its surface caused by friction.

[0004] An auxiliary device for hoisting a gyratory cone crusher is characterized by comprising a horizontal tube and a limiting plate. An end plate is welded to one end of the horizontal tube, and lifting lugs are welded to the outer side of the end plate. At least four positioning holes are evenly distributed on the tube wall on the side of the horizontal tube away from the end plate. A through hole with a diameter matching the outer diameter of the horizontal tube is formed in the middle of the limiting plate. A positioning plate is fixed around the outer periphery of the through hole, with the number of positioning plates matching the number of positioning holes. A waist hole is formed on the positioning plate. Lifting lugs are welded to the side of the limiting plate. After the limiting plate passes through the through hole into the horizontal tube, bolts or pins are used to pass through the waist hole and the positioning hole to fix the limiting plate to the horizontal tube. Horizontal plates are horizontally welded to the bottom of the end plate and the limiting plate, and the two horizontal plates are located on the same plane. Steel cables are threaded through the lifting lugs on the end plate and the limiting plate, and the two steel cables are connected to each other.

[0005] Furthermore, the spacing between the horizontal plates is greater than the width of the suspension component at the top of the gyratory breaking cone.

[0006] Furthermore, the plane of the horizontal plate is semi-circular, and its diameter is greater than the width of the limiting plate and the end plate.

[0007] The beneficial effects of this utility model are as follows: The bolt fixing of the limiting plate to the horizontal tube simplifies the installation process, significantly saving labor and time. The position of the limiting plate is adjustable, and the positioning holes and waist holes can be matched to accommodate suspension components of different sizes, improving the applicability of the device. The horizontal plate abuts against the top surface of the moving cone, combined with the interconnected steel cables, effectively suppressing swaying and rotation during hoisting, avoiding collisions with surrounding buildings or equipment. Furthermore, the semi-circular design and reasonable spacing of the horizontal plate reduce direct friction between the slings and the surface of the moving cone, reducing surface wear and extending service life. The double-headed bolts fixing the limiting plate and the steel cable connection strengthen the overall structural rigidity, ensuring a stable and reliable hoisting process.

[0011] Example 1: An auxiliary device for hoisting a gyratory crushing cone, characterized in that it includes a horizontal pipe 1 and a limiting plate 2. An end plate 3 is welded to one end of the horizontal pipe, and a lifting lug 6 is welded to the outer side of the end plate 3. At least four positioning holes are evenly opened on the pipe wall on the side of the horizontal pipe away from the end plate. A through hole with a diameter consistent with the outer diameter of the horizontal pipe 1 is opened in the middle of the limiting plate 2. A positioning plate 4 is fixed around the outer periphery of the through hole. The number of positioning plates 4 is consistent with the number of positioning holes. Waist holes 5 are opened on the positioning plates. The lifting lug 6 is welded to the side of the limiting plate. The limiting plate 2 passes through the through hole into the horizontal pipe 1. After pipe 1, bolt 7 is used to fix the limiting plate 2 to the horizontal pipe 1 through the waist hole 5 and the positioning hole. In this embodiment, the bolt 7 used is a double-headed bolt. The end plate 3 and the bottom of the limiting plate 2 are horizontally welded with a horizontal plate 8. The plane of the horizontal plate 8 is semi-circular, and its diameter is greater than the width of the limiting plate 2 and the end plate 3. The distance between the two horizontal plates is greater than the width of the top suspension component of the swivel breaking cone, and the two horizontal plates 8 are located on the same plane. The steel cable 9 is inserted into the lifting lug 6 on the end plate 3 and the limiting plate 2, and the two steel cables 9 are connected to each other.

[0012] In use, the hoisting sling of the central machine is inserted into the horizontal tube and placed near the end plate 3. The horizontal tube 1 is then inserted into the lifting hole of the suspension component at the top of the gyratory crushing cone, and the hoisting sling of the other side is inserted. The limiting plate 2 is then inserted, and its position is adjusted according to the width of the suspension component. The limiting plate 2 is then fixed in place using double-cap bolts 7. The two steel cables 9 are connected to each other to strengthen the connection between the horizontal tube 1 and the limiting plate 2. An electric hoist is then attached to the connection point of the two steel cables 9, allowing the device to be moved using the electric hoist. The horizontal plate 8 not only abuts against the top surface of the gyratory crushing cone to prevent it from swaying, but also prevents damage caused by friction between the crane's hoisting sling and the surface of the crushing cone.
