Description

Unhooking-proof coiler mandrel lifting appliance

Technical Field

The utility model belongs to steel rolling machinery equipment field especially relates to a can prevent coiler drum hoist of unhook.

Background

When a coiling machine of a production line for hot rolling 1580mm of saddle steel is used for replacing a coiling drum, a lifting appliance for disassembling and assembling the coiling drum is needed, the height of the lifting appliance is 5 meters, the width of the lifting appliance is 4 meters, the weight of the lifting appliance is 15 tons, and the weight of the lifting coiling drum is 17 tons. When the lifting appliance is normally used, the connecting plate on the lifting appliance is hung on the hook head of the crane shoe-shaped ingot, and the hook head of the crane shoe-shaped ingot and the connecting plate are tensioned by the dead weight of the lifting appliance. Although two support rods for supporting and fixing are arranged between the connecting plates on the two sides, if the bottom of the lifting appliance contacts the ground or an equipment supporting point during operation, a gap is generated between the hook head of the crane shoe-shaped ingot and the connecting plate of the lifting appliance, so that the lifting appliance is inclined, and in severe cases, the connecting plate can be inclined to one side and separated from the hook head of the crane shoe-shaped ingot. If the predicted unhooking and dumping accident occurs to the lifting appliance, great damage is inevitably caused to surrounding operators and equipment, and the accident that the connecting plate on one side is unhooked already occurs in the field use process.

Disclosure of Invention

The utility model aims at providing a can guarantee that the connecting plate can neither open nor can break away from with crane ingot hook when contact ground or fixed equipment of hoist, make the reel operation of changing normally go on, ensure the unhook-proof coiler reel hoist of personnel and equipment safety.

Therefore, the utility model discloses the technical solution who takes does:

the utility model provides an mousing-hook coiler reel hoist, is including connecting the overhead both sides connecting plate of crane ingot hook and supporting two spinal branch vaulting poles of fixed both sides connecting plate, a horizontal U-shaped cassette has clamped respectively on two spinal branch vaulting poles, be equipped with the bolt hole on two side legs of U-shaped cassette respectively, all be equipped with double-end screw in the bolt hole of two cassettes, double-end screw's two are passed through lock nut and are fixed the cassette respectively on two spinal branch vaulting poles, pass through double-end screw simultaneously, lock nut and cassette are fixed two spinal branch vaulting poles locking together.

The utility model has the advantages that:

after the anti-unhooking device consisting of the U-shaped clamping seat, the double-end screw and the locking nut is additionally arranged, the connecting plate can be prevented from being opened and being separated from the ingot hook head of the crane when the lifting appliance is in contact with the ground or fixed equipment, so that the reel replacement operation can be safely and normally carried out, and the safety of operating personnel and surrounding equipment is ensured.

FIG. 2 is a top view of the mousing-hook coiler drum sling;

fig. 3 is a schematic view of the unhooking prevention device.

In the figure: crane ingot gib head 1, cassette 2, lock nut 3, connecting plate 4, double threaded screw 5, bracing piece 6.

Detailed Description

As can be seen from the attached drawings, the utility model discloses mousing-hook coiler reel hoist, including connecting both sides connecting plate 4 on crane shoe-shaped gold ingot gib head 1 and supporting two spinal branch vaulting poles 6 of fixed both sides connecting plate 4. A transverse U-shaped clamping seat 2 is clamped on two support rods 6 respectively, bolt holes are formed in two side legs of the U-shaped clamping seat 2 respectively, double-end screws 5 are arranged in the bolt holes of the two clamping seats 2 respectively, two ends of each double-end screw 5 are fixed on the two support rods 6 through locking nuts 3 respectively, and the two support rods 6 are locked and fixed together through the clamping seats 2, the locking nuts 3 and the double-end screws 5. The support rod 6 is made of round steel with the diameter of 80mm, and the double-end screw 5 is made of 2 round steel with the diameter of M24 multiplied by 1000 mm.

When the lifting appliance is used, 2U-shaped clamping seats 2 are clamped on the supporting rod 6, 2 double-end screws 5 are used for connecting the clamping seats 2, and 4 locking nuts 3 are installed on the double-end screws 5 and fastened. Can guarantee that connecting plate 4 can not part because of external force in the hoist use to avoid appearing the unhook accident of empting, guarantee personnel and equipment safety.
