[0045] In this paper, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0046] In addition, in the description of the present application, the terms "first", "second" and the like are only used for differentiation and description, and cannot be understood as indicating or implying relative importance.
[0047] Reference Figures 1-10For the first embodiment of the utility model, propose a kind of from unhooking high line spreader, comprising: main body 1;Supporting shaft 2 slidingly arranged on main body 1;Hook 3 is swinged in supporting shaft 2, hook 3 is configured to swing after being subjected to external force, and supporting shaft 2 is slid, and hook 3 is driven;Anti-escape closure rod 4 is movably arranged on main body 1, and is connected with supporting shaft 2, supporting shaft 2 is configured to drive anti-escape closure rod 4 to abut or cancel abutment hook 3 after sliding;After anti-escape closure rod 4 abuts hook 3, the anti-escape closure area 5 of both is formed.
[0048] In the embodiment, the use process of the high line spreader is as follows:
[0049] As shown in Figures 8-10 , first, use magnetic type from unhooking form, before lifting goods, first swing hook 3 by external force, make the top of hook 3 and the counterweight block 10 integrated with it adsorbed on the magnetic attraction block 11 on the top of steel structure main body 1, make the bottom hook 3 present substantially vertical state, facilitate to hook goods, then operator uses crane to move from unhooking spreader to the above of high line goods, lower hook 3, connect hook 3 and high line goods firmly, then hoisting machinery lifts hook 3, and moves to the above of specified position on ship, finally hoisting machinery stops lifting action, gradually lowers high line, from unhooking spreader makes hook 3 rotate using counterweight block 10 or the gravity of hook 3 itself, with the rotation of hook 3, the connection between hook 3 and high line goods gradually loosens, finally realizes the automatic unhooking of goods, completes the loading of high line.
[0050] For the effect of anti-escape closure rod 4, in the process of lifting high line, due to the gravity of goods, supporting shaft 2 is forced to slide downward, and then drives anti-escape closure rod 4 to move to abut with hook 3, automatically forms anti-escape closure area 5 using the property of goods, avoids active power source to make structure complex, and the closure effect is good, and the closure force is completely dependent on the gravity of goods, and generally such high line goods are also heavy.
[0051] And when lowering unhooking, unlike traditional magnetic type from unhooking, it will first make supporting shaft 2 slide reset, and hook 3 swings to complete unhooking under the action of counterweight block 10 in the reset process.
[0052] Compared with traditional magnetic type from unhooking, anti-escape closure rod 4 movably arranged on main body 1 is additionally arranged, the spreader can utilize the gravity property of goods, automatically drive anti-escape closure rod 4 and hook 3 to form anti-escape closure area 5 when lifting, form similar "self-locking" form, only when lowering, it will reset, unhook by opening anti-escape closure area 5.
[0053] Specifically, in order to improve the processing efficiency, the lifting appliance can use a 1.2-meter lifting beam as the main component of the lifting appliance, and replace the ordinary lifting hook 3 with a magnetic self-unhooking device. One time, 1-5 pieces of high line can be lifted. The width of the main component of the lifting appliance is 0.8 meters, and the width of the goods is about 6 meters when 5 pieces of high line are lifted at a time. Most ship types can send the high line to the innermost side of the edge position. In special cases, when the edge position is relatively deep, the lifting appliance can be adjusted to lift 7 pieces of high line at a time by adjusting the lifting system and the sling structure of the lifting appliance. In this way, the self-unhooking effect is good after the goods are stably dropped in the cabin. The number of single lifting can be flexibly adjusted according to the working environment in the cabin, and the maximum number of single lifting is 7.
[0054] And the form that each component can adopt is that the anti-falling closed rod 4 is movably arranged at the bottom of the main body 1 and closer to the lifting hook 3, the lifting hook 3 swings around the horizontal axis, and the support shaft 2 and the anti-falling closed rod 4 both move in the vertical direction, so as to more quickly receive the gravity of the goods to form the anti-falling closed area 5. The magnetic block 11 can be detachably arranged at the top of the main body 1 by means of bolts or the like, so as to be convenient for replacement or position adjustment.
[0055] It is worth mentioning that the support shaft 2 needs to have a reset function for sliding. On the basis of considering the control cost and simplifying the structure, a spring can be directly installed in the groove in which the support shaft 2 slides. Although the high line goods are heavy, the spring may be damaged for a long time under the pressure, so a high-carbon steel spring or the like with a hard property needs to be used. The connection form of the anti-falling closed rod 4 and the support shaft 2 can adopt fixed connection or detachable connection, as long as it can drive the anti-falling closed rod 4 to move.
