Description
Technical Field
[0001] The utility model belongs to the technical field of cranes, and particularly relates to a crane hook. Background Technique
[0002] A crane refers to a multi-action lifting machine that vertically lifts and horizontally transports heavy objects within a certain range. Also known as overhead crane, gantry crane, crane. The main characteristics of a tire crane are: its driving cab and lifting control cab are combined into one, and it is evolved from a crawler crane (crawler crane). The crawler and walking support parts of the walking mechanism are changed into a chassis with tires, overcoming the disadvantage that the crawler plates of the crawler crane (crawler crane) damage the road surface, and it belongs to a material handling machine. A bridge crane is a lifting equipment that spans over workshops, warehouses, and yards for material lifting. Since its two ends are located on tall concrete columns or metal brackets, it looks like a bridge. The bridge of the bridge crane runs longitudinally along the tracks laid on the high racks on both sides, and can make full use of the space under the bridge to lift materials without being hindered by ground equipment. It is the most widely used and most numerous type of lifting machine. Some working characteristics of lifting equipment are intermittent movements, that is, in a working cycle, the corresponding mechanisms for material taking, transporting, unloading, etc. work alternately. The development and use of cranes in the market are becoming more and more extensive.
[0003] When a crane hoists an object, a hook is needed to lift the object. However, when a general hook is used, it cannot be well connected to the lifting rope and cannot be restricted, and the object is prone to unhooking, resulting in an impact on the use effect. Content of the Utility Model
[0004] To solve the problems raised in the above background technique, the utility model provides a crane hook, which solves the problems that it cannot be well connected to the lifting rope and cannot be restricted, and the object is prone to unhooking.
[0005] To achieve the above object, the utility model provides the following technical solution: A crane hook includes a receiving block, a connecting block is arranged at the bottom of the receiving block, a hook is arranged at the bottom of the connecting block, a groove is opened on one side of the receiving block, a third fixing plate is arranged inside the groove, rope grooves are respectively opened on one side of the third fixing plate and the groove, a first fixing plate is arranged at the top of the receiving block, a second fixing plate is arranged on one side of the first fixing plate, bolts are respectively arranged on one side of the second fixing plate, and one end of the bolt passes through the second fixing plate and the first fixing plate and is threadedly connected with a nut.
[0006] Preferably, a limiting column is arranged on one side of the rope groove, and one end of the limiting column slidably penetrates through the third fixing plate.
[0007] Preferably, connection holes are respectively formed around the groove. Threaded posts are respectively arranged around one side of the third fixing plate, and the threaded posts are located inside the connection holes. A hexagonal ring is threadedly connected to the surface of the threaded post, and the hexagonal ring is located on one side of the receiving block.
[0008] Preferably, second threaded holes are respectively formed on one side of the receiving block, and the second threaded holes extend into the receiving block through the connection block. A first internal hexagonal bolt is threadedly connected inside the second threaded holes.
[0009] Preferably, connecting plates are respectively arranged on both sides of the connection block. An installation hole is formed at one end of the connecting plate. A connecting shaft is movably connected inside the installation hole. A limiting frame is connected to the surface of the connecting shaft. A tension spring is arranged on the top of the limiting frame, and one end of the tension spring is connected to the receiving block. A limiting card slot is formed at one end of the hook, and one end of the limiting frame is located inside the limiting card slot.
[0010] Preferably, a first threaded hole is formed at the other end of the connecting plate, and the first threaded hole penetrates through the connecting plate and extends into the connection block. A second internal hexagonal bolt is threadedly connected inside the first threaded hole.
[0011] Preferably, limiting blocks are respectively arranged on the surface of the connecting shaft, and the limiting blocks are located inside the connecting plate.
[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0013] When in use, the lifting rope is located inside the rope groove, and one end of the lifting rope moves out of the rope groove through the limiting post. Then, the third fixing plate moves inside the groove, the threaded post passes through the connection hole, and then the hexagonal ring moves on the surface of the threaded post, so that the hexagonal ring tightens and pulls the threaded post, driving the third fixing plate to clamp the lifting rope. At the same time, the moved-out lifting rope is located inside the first fixing plate and the second fixing plate. By rotating the bolt and the nut, the second fixing plate is driven to move, and the second fixing plate moves closer to the first fixing plate to fix the lifting rope, increasing the stability and convenience of the connection, improving the connection effect. And when in use, due to the pulling force of the tension spring, the limiting frame is driven to have an outward force, so that the limiting frame is always located inside the limiting card slot, thus preventing the item from being unhooked and increasing the use effect.
