Description

Technical Field

[0001] The utility model relates to the technical field of tower crane hoisting components, in particular to a stable rotating component for tower crane hoisting components. Background Art

[0002] With the continuous expansion of the scale of construction projects and the improvement of construction progress requirements, tower cranes will be needed to transport and transfer objects, and the tower crane's hoisting rotating assembly needs to keep the hoisted objects stable during the rotation process.

[0003] However, the current hoisting object rotation assembly is an upper fixed ring and a lower fixed ring that are clamped together. This will inevitably cause shaking during the transportation of the hoist, resulting in friction and gradual wear of the contact surfaces, causing the connection to become stuck or loose. For this reason, we propose a stable rotation assembly for tower crane hoists. Utility Model Content

[0004] The purpose of the utility model is to provide a stable rotating assembly for tower crane hoisting objects, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a stable rotating assembly for tower crane hoists, comprising a fixed plate and a fixed ring, a hook body fixedly connected to one side of the bottom end of the fixed plate, a connecting column fixedly connected to the middle of the top of the fixed plate, and a groove in the middle of the outer wall of the connecting column and the fixed ring are clamped with each other, a plurality of notches are provided at the angles of the lower end of the fixed ring, a plurality of the notches are rotatably connected to telescopic rods through rotating shafts, the upper ends of the rod walls of a plurality of the telescopic rods are fixedly connected to limiting blocks, the bottom ends of a plurality of the telescopic rods are fixedly connected to connecting blocks, a plurality of springs are fixedly connected between the connecting blocks and the limiting blocks and are sleeved on the outer ends of the telescopic rods, and the bottom ends of a plurality of the connecting blocks are fixedly connected to arc blocks.

[0006] Preferably, a limiting rod is provided at the bottom edge of the fixed plate.

[0007] Preferably, a baffle is fixedly connected to the top edge of the fixed disk.

[0008] Preferably, connecting rings are fixedly connected to both side edges of the top end of the fixing ring.

[0009] Preferably, a circular groove is provided at the top edge of the fixing plate, and the plurality of arc-shaped blocks are all clamped in the circular groove.

[0010] Compared with the prior art, the beneficial effect of the present invention is that through the linkage and coordination of several notches, telescopic rods, springs, limit blocks, connecting blocks, arc blocks and circular grooves provided on the fixed ring, when the fixed ring is caused to shake during cargo transportation, the degree of wear between the fixed ring and the connecting column can be reduced, thereby increasing the service life of the rotating assembly.
