Description

Spreader disk

Technical field

The utility model relates to hanging device, particularly a kind of spreader disk.

Background technology

Spreader disk is the hanging device of using always, is mainly used in occasions such as bulk storage plant, dock, harbour, station.Traditional spreader disk is generally translation chute-type suspender, and relatively Clamping force is less, and easy slippage when lifting disc suspended object makes suspended object come off easily and causes danger in the use.In addition, some suspender hangs lock and is adopted as left and right sides spiral chute when lifting by crane automatically and unclamping, this structure is bigger to the wearing and tearing of locking bar and lock, slow in one's movements when unclamping in the lifting of spreader disk, efficient is low, is unfavorable for realizing efficient, continuous automation mechanized operation.

The utility model content

The purpose of this utility model is to overcome the above-mentioned defective of known technology, provides a kind of Clamping force simple in structure, relative big and less and can realize lifting by crane and the spreader disk that unclamps the continuous and automatic operation to the wearing and tearing of locking bar and lock.

The spreader disk that the utility model provides, comprise that hanging scaffold, suspension ring, hanger and rotation hang lock, rotation is hung lock and is comprised lock tube, locking bar, lock, spring and elastic force pilot pin, also comprise a toggle, first rotating shaft, second rotating shaft and base, hanger and toggle have a plurality of respectively, be distributed on the hanging scaffold, hanger and toggle are hinged and connected by first rotating shaft, and toggle is hinged and connected by second rotating shaft and base; Lock tube is installed in the positive center below the hanging scaffold, lock is installed in the positive center above the base, the locking bar bottom is a flat circular cone, its top places lock tube by spring, lock is provided with the T slot that matches with locking bar, the locking bar sidewall is provided with and the movable straight line dextrorotation continuous helical groove that cooperates of elastic force pilot pin, and the plug helix anglec of rotation of straight line dextrorotation continuous helical groove is 90 °.

The utility model spreader disk, wherein said toggle comprise connecting rod and the tong arm that is hinged and connected by the 3rd rotating shaft, and connecting rod and hanger are hinged and connected by first rotating shaft, and tong arm and base are hinged and connected by second rotating shaft.

The utility model spreader disk, wherein said hanger and described toggle have 3 respectively.

The advantage and the good effect of the utility model spreader disk are: owing to adopted toggle, compare with known translation chute-type suspender, utilize the relative Clamping force of crank levers bigger, be difficult for slippage during lifting disc suspended object, also reduced the wearing and tearing of locking bar and lock.Adopted the straight line right-hand helix owing to hang the automatic rotation of lock again, the track of locking bar action is the fluctuating shape, and direct motion forward is difficult for causing the locking bar counter-rotating, can realize the lifting of spreader disk and unclamp the continuous and automatic operation.The utility model spreader disk is simple in structure, and is safe in utilization.

The specific embodiment

Embodiment 1

See figures.1.and.2, the utility model spreader disk comprises hanging scaffold 1, suspension ring 2, rotates and hang lock 3, hanger 4, first rotating shaft 5, connecting rod 6, tong arm 7, base 8, second rotating shaft 16 and the 3rd rotating shaft 17.With reference to Fig. 6, rotation is hung lock 3 and is comprised lock tube 15, locking bar 11, lock 14, spring 9 and elastic force pilot pin 10.

Spreader disk is a main component by hanging scaffold 1, and the suspension ring 2 that can articulate with lifting appliance are equipped with at positive center above the hanging scaffold 1, below positive center be equipped with and can make suspender realize that the rotation of continuous action hangs lock 3.Connecting rod 6, tong arm 7, first rotating shaft 5, second rotating shaft 16 and the 3rd rotating shaft 17 constitute toggle.Hanger 4 and toggle have 3 respectively, with the 120 uniform peripheries that are welded on below the hanging scaffold 1.Each hanger 4 adopts first rotating shaft 5 to be hinged and connected with connecting rod 6, and connecting rod 6 is hinged and connected with tong arm 7 by the 3rd rotating shaft 17, and tong arm 7 is hinged and connected with base 8 by second rotating shaft 16.

With reference to Fig. 6 to Fig. 9, lock tube 15 is installed in the positive center below the hanging scaffold 1, and lock 14 is installed in the positive center above the base 8.Locking bar 11 bottoms are a flat circular cone, promptly cut away a part on S. A. both sides, cone upper edge symmetrically and form flat-shaped head, are provided with spring 9 between the top of locking bar 11 tops and lock tube 15, and lock 14 is provided with the T slot that cooperates with locking bar 11.The sidewall of locking bar 15 is provided with and the elastic force pilot pin 10 movable straight line dextrorotation continuous helical grooves 12 that cooperate, and the plug helix anglec of rotation of straight line dextrorotation continuous helical groove 12 is 90 °.

The following describes the method for manipulating of the utility model spreader disk.

When the lifting operation, by lifting by crane and put down hanging scaffold 1 with suspension ring 2 bonded assembly lifting appliances, with the contacted base 8 of suspended object under the effect of the hinge that toggle constitutes, make tong arm 7 finish the action of upholding and shrinking, the effect that reaches lifting and unclamp suspended object.With reference to Fig. 3 to Fig. 5, be respectively the configuration state of folder extension state, designed openings state and free state lower disc suspender.

For work automatically continuously, when spreader disk was in free state (state does not stress), with reference to Fig. 6, rotation was hung lock 3 and is in initial condition.When lifting appliance begins to lift by crane spreader disk, rotation is hung lock 3 and is borrowed deadweight and spring 9 under 10 effects of elastic force pilot pin, impel locking bar 11 along 90 ° of straight line dextrorotation continuous helical groove 12 fast rotational, because of locking bar head 13 is a flat circular cone, so make on its T slot that is stuck in lock 14, with reference to Fig. 7, at this moment suspender is in the maximum open state.When lifting appliance puts down spreader disk and makes it be in free state, under spreader disk deadweight effect, make locking bar 11 along straight line dextrorotation continuous helical groove 12 half-twists once more, with reference to Fig. 8, at this moment hang lock locking bar 13 heads and contact with lock 14 bottom surfaces.Repeat primary lifting operation again, with reference to Fig. 9, hang lock locking bar 11 equally along straight line right hand helix groove 12 half-twists, make locking bar head 13 deviate from the T slot of lock, at this moment spreader disk is in folder extension state.So repetitive operation can realize spreader disk work automatically continuously.

As can be seen, this is greatly improved on original suspender basis:

1, with reference to Figure 10, locking bar 11 is contoured curve 18 along straight line dextrorotation continuous helical groove action De Gui Trace, and direct motion forward is difficult for causing locking bar 11 counter-rotating and slippages.

2, be to realize the lifting of spreader disk and unclamp continuous and automatic, the track that hangs the action of lock locking bar is the fluctuating shape, and direct motion forward is difficult for causing locking bar to reverse.

3, spreader disk and known translation chute-type suspender structure compared are simple, owing to adopted the crank levers application force, Clamping force is bigger relatively.

4, adopt the straight line helix line owing to hang the automatic rotation of lock, reduced the wearing and tearing of locking bar and lock, prolonged the service life of suspender, improved safety.

Embodiment recited above is described preferred implementation of the present utility model; be not that design of the present utility model and scope are limited; do not breaking away under the utility model design plan prerequisite; common engineering staff make the technical solution of the utility model in this area various modification and improvement; all should fall into protection domain of the present utility model; the technology contents that the utility model is asked for protection all is documented in claims.
