[0002] At present, for hoisting equipment and production lines, the traditional manual docking method can hardly meet the production needs of the industry. Taking the semiconductor silicon crystal growth process as an example, the industry still uses traditional screw locking mechanisms for hoisting, which has low production efficiency and high risks of manual climbing operations. In addition, the temperature of the crystal rod is high when it comes out of the furnace, which poses a risk of burns and is a high-risk operation. Summary of the invention

[0003] The purpose of the present invention is to address the defects and shortcomings of the prior art and provide a vertical lifting structure with automatic docking and undocking, which can be used in high temperature environments and various complex environments, reduces the risk of direct participation of personnel, can replace manual operations, reduce manual labor, is stable, and highly practical, while saving time and having high production efficiency.

[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: it comprises a hook body, a hook fixing block, a hook and a rivet; the bottom of the hook body is connected to a hook retraction plate by a connecting column, and several hook fixing blocks are fixed at equal angles on the bottom of the hook retraction plate, and the lower end of the hook fixing block is rotatably connected to the hook by a connecting rod, and a spring fixing block is fixed to the outer side of each hook fixing block, and a spring is connected between the inner side of the spring fixing block and the outer side of the upper part of the hook; the rivet movable hook is arranged between several hooks, and a hook release ring is arranged on the movable sleeve of the rivet.

[0005] By adopting the above design scheme, the main body of the hook is fixed on the lifting power end, and the rivet is fixed on the object to be lifted. The lifting mechanism is lowered to drive the main body of the hook to descend, and under the rebound action of the spring, it is connected with the rivet and then lifted up to achieve lifting. When the object reaches the specified position, the lifting mechanism is lowered, and after the object is placed at the specified position, it continues to descend so that the hook passes the unhooking ring. The lifting mechanism drives the main body of the hook to rise. At this time, the unhooking ring is driven to rise at the same time until the unhooking ring contacts the bottom of the rivet and continues to lift. The hook is stretched open by the unhooking ring, so that the hook is separated from the unhooking ring and thus separated from the rivet.

[0006] Preferably, the upper end of the rivet is arranged in a frustum-shaped structure.

[0007] Preferably, a hook angle is integrally formed inwardly at the bottom of the pull hook, and an outer side wall of the hook angle is provided with an inclined surface from inside to outside from top to bottom.

[0008] Preferably, an annular slope is provided on the periphery of the bottom of the unhooking ring, and the diameter of the annular slope is arranged from small to large from bottom to top, and the end of the hook angle of the pull hook movably contacts the annular slope.

[0009] Preferably, a receiving ring is integrally formed on the column of the rivet, and the unhooking ring is movably mounted on the receiving ring.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention provides a vertical lifting structure with automatic docking and unhooking, which can be used in high temperature environments and various complex environments, reduces the risk of direct personnel participation, can replace manual operations, reduce manual labor, is stable, and highly practical, while saving time and having high production efficiency.

DETAILED DESCRIPTION

[0018] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. The preferred embodiments in the description are only used as examples, and all other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of the present invention.

[0019] like Figure 1-Figure 6As shown, this specific embodiment adopts the following technical scheme: it comprises a hook body 1, a hook fixing block 4, a hook 6 and a rivet 8; the bottom of the hook body 1 is connected to a hook retraction plate 2 by means of a connecting column 10 (the connecting column 10 is penetrated in the hook retraction plate 2 and is fixed by means of an end cap integrally formed at the bottom end of the connecting column 10), a plurality of hook fixing blocks 4 are fixed at equal angles at the bottom of the hook retraction plate 2, the lower end of the hook fixing block 4 is rotatably connected to the hook 6 by means of a connecting rod 5, a spring fixing block 3 is fixed to the outer side of each hook fixing block 4, and the inner side of the spring fixing block 3 is connected to the outer side of the upper part of the hook 6 There is a spring 7; the rivet 8 is movable between several hooks 6, and a detaching ring 9 is movably sleeved on the rivet 8; the upper end of the rivet 8 is arranged in a frustum-shaped structure; the bottom of the hook 6 is integrally formed with a hook angle toward the inside, and the outer wall of the hook angle is provided with an inclined surface 6-1 from inside to outside from top to bottom, and the outer periphery of the bottom of the detaching ring 9 is provided with an annular inclined surface 9-1, and the diameter of the annular inclined surface 9-1 is arranged from small to large from bottom to top, and the end of the hook angle of the rivet 6 movably contacts the annular inclined surface 9-1, and a receiving ring 8-1 is integrally formed on the column of the rivet 8, and the detaching ring 9 is movably mounted on the receiving ring 8-1.

[0020] When using the present invention, first fix the main body of the hook 1 to the lifting power end, then fix the rivet 8 to the object to be lifted, the lifting mechanism descends, driving the main body of the hook 1 to descend, and after the inclined surface 6-1 at the lower end of the hook 6 contacts the inclined surface of the frustum-shaped structure at the upper end of the rivet 8, the hook 6 is stretched open and continues to descend until the lower end of the hook 6 contacts the bottom of the frustum-shaped structure at the upper end of the rivet 8. Under the rebound action of the spring 7, the hook corner at the lower end of the hook 6 is inserted between the rivet 8 and the unhooking ring 9, thus achieving docking; then, the lifting machine is controlled The structure is lifted up to realize hoisting; when the object reaches the specified position, it is lowered through the hoisting mechanism, and after placing the object at the specified position, it continues to descend, so that the hook 6 passes over the unhooking ring 9. At this time, the end of the hook angle of the hook 6 contacts the annular inclined surface 9-1, and the hoisting mechanism drives the hook body 1 to rise. At this time, the unhooking ring 9 is driven to rise at the same time until the unhooking ring 9 contacts the bottom of the frustum-shaped structure at the upper end of the rivet 8, and continues to lift. The hook 6 is opened under the action of the annular inclined surface 9-1, so that the hook 6 is separated from the unhooking ring 9, and thus separated from the rivet 8.
