Drawings

The invention will be further described with reference to the following figures and examples:

fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

Fig. 1 is the utility model discloses a schematic structure diagram, as shown in the figure, cantilever omnidirectional rotation's in this embodiment hoisting device includes buckle subassembly, gallows stand 3, preceding cantilever 4 and chain block 5, buckle subassembly fixed mounting is on the fixed beam body 1 of job site, gallows stand 3 passes through buckle subassembly axial fixity just can 360 rotations for rotation center along vertical direction extension and its axis, the top of gallows stand 3 is provided with and is used for the installation preceding cantilever 4 of chain block 5, gallows stand 3 can be in vertical direction 360 rotatory location when just can guaranteeing the hoist and mount crossbeam, has brought very big facility for the workman is under construction, has improved the efficiency of construction.

In this embodiment, the buckle assembly includes the lock in buckle 2 of fixed roof beam body 1 top, be used for fastening buckle 2's adjusting screw 22 and be used for installing the tubular column groove 23 of gallows stand 3, tubular column groove 23 fixed connection in buckle 2 top just extends along vertical ascending direction, gallows stand 3 lower extreme cartridge in tubular column groove 23, the degree of depth of tubular column groove 23 can satisfy the demand of axial fixation gallows stand 3, and gallows stand 3 can satisfy the angular adjustment needs when hoisting the steel crossbeam in tubular column groove 23 arbitrary rotation.

In this embodiment, the buckle including laminate in two buckle arms 21 of fixed roof beam body 1 both sides form the downward spill structure of opening, be provided with at least one adjusting screw 22 on the buckle arm 21, adjusting screw 22's effect end butt in the side of fixed roof beam body 1, adjusting screw 22 threaded connection in its terminal butt in the side of fixed roof beam body 1 on buckle arm 21 guarantees that buckle 2 laminates in the surface of fixed roof beam body 1 firmly, provides a good fixed mounting basis for gallows stand 3, guarantees going on smoothly of follow-up hoist and mount.

In this embodiment, the assembly section of the hanger column 3 and the pipe column groove 23 is cylindrical, the outer diameter of the assembly section is slightly smaller than the inner diameter of the pipe column groove 23, a gap is formed between the hanger column 3 and the pipe column groove 2 for applying lubricating oil, so that the friction resistance of the hanger column 3 is small when the hanger column rotates relative to the pipe column groove 23, the friction torque required during rotation is reduced, and the construction is more labor-saving.

In this embodiment, the front cantilever 4 can for the gallows stand 3 rotates in vertical direction, and front cantilever 4 sets up with rotatable mode in the top of gallows stand 3 is also for giving the rotation that can adjust of the crossbeam of hoist and mount, and the rotation of the rotatory stack front cantilever 4 in bottom of gallows stand 3 can satisfy just can guarantee that the crossbeam of hoist and mount does some necessary angular adjustment through a rotation when the construction position is limited, avoids appearing because the position interferes or the rotatory condition emergence of too narrow and small inoperable of construction position, has improved hoist device's suitability.
