Description

Technical Field

[0001] The utility model relates to the technical field of hoisting chains, in particular to an adjustable stable hoisting chain. Background Art

[0002] Lifting chains are a commonly used hanging component in cranes. They are used to lift heavy and large goods. Lifting chains are generally composed of lifting chains, lifting frames and hooks. Lifting chains on the market need to be replaced with chains of different lengths when lifting goods of different widths.

[0003] Application number: CN202222740698.3 discloses an adjustable stable lifting chain, including a lifting frame, an empty slot is opened inside the lifting frame, and fixed blocks are arranged on both sides of the empty slot, a threaded hole is opened on the surface of the fixing block, a threaded rod is passed through the threaded hole, a connecting ring is fixed on the lower surface of the fixing block, and an open slot is opened on the lower surface of the lifting frame. The utility model is provided with a fixing block, a threaded rod and a motor, etc. When the threaded rod rotates, the fixing block can be driven to move through the threaded hole of the fixing block, and the movement of the fixing block can drive the lifting chain to move, so that the distance between the lifting chains can be adjusted, and the fixing rod can make the connecting rod movable by rotating in the fixing hole, and the movement of the connecting rod facilitates personnel to open and close the connecting rod, and the connecting rod can close the hook opening, so that the hook hangs the goods more stably.

[0004] The existing patented lifting chain uses a motor-driven threaded rod to move a fixed block, and then the moving fixed block moves the chain apart to adjust the distance between the chains. When the chain lifts a heavy object, the fixed block applies downward pressure to the thread on the surface of the threaded rod, and the thread structure on the surface of the threaded rod has poor force resistance and is prone to thread damage, which results in the threaded rod used for adjusting the lifting chain needing to be replaced frequently, and the connecting rod at the hook below the chain is also relatively simple, which is easy to limit the size of the hook hanging into the rope when preventing it from falling off, thereby affecting the stability of the chain lifting. For this reason, we propose an adjustable stable lifting chain. Utility Model Content

[0005] The main purpose of the utility model is to provide an adjustable and stable lifting chain. By setting a lifting chain for lifting materials, this lifting chain uses an electric push rod to drive the I-shaped plate of the lifting chain body to adjust the variable distance at the support plate, thereby adjusting the lifting width between the lifting chain bodies, so that the hook under the chain body can stably lift the rope of the material for lifting and transportation, and the restriction of the wire rope at the chain body with the carabiner will not affect the number and size of the lifting rope at the hook. At the same time, compared with the threaded chain body displacement structure, the electric push rod used to drive the chain body does not need to bear the lifting force of the chain body, and there is no wear of the threaded structure, which ensures the adjustable and stable lifting of the lifting chain and can effectively solve the problems in the background technology.

[0025] The side mounting plates 17 are symmetrically welded to the plate surface of the outer sealing plate 3, and the side mounting plates 17 are symmetrically clamped on the outside of the two sets of plate bodies of the supporting plates 2, and the side mounting plates 17 are fastened with bolts between the supporting plates 2;

[0026] By adopting the above technical solution, the outer sealing plate 3 is connected to the supporting plate 2 for a second time by the side mounting plate 17, thereby improving the connection firmness between the outer sealing plate 3 and the supporting plate 2.

[0027] The buckle body of the shackle 11 is penetrated with a U-shaped plate 10 and a chain ring of the chain body 12;

[0028] By adopting the above technical solution, the shackle 11 can be normally installed with its own pin after passing through the chain loops of the U-shaped plate 10 and the chain body 12, thereby realizing the connection between the U-shaped plate 10 and the chain body 12 by the shackle 11.
