Abstract

The utility model relates to an automatic unhooking device for a steel cable. The utility model comprises a shifting fork which is fixedly connected with a suspension hook 8 and is provided with a driving device. The shifting fork is composed of a front shifting fork 10 and a rear shifting fork 9, a fixed included angle is formed between the two shifting forks which are provided with restoring springs, and the outer side of the front shifting fork 10 is provided with a steel cable unhooking-proof rod 11. The utility model can automatically unhook after goods is suspended and transported to a destination, so operators do not need to enter a danger area to unload the goods. After one end of the steel cable is unloaded, the steel cable is withdrawn from below the goods by a hoisting machine and the whole steel cable is unloaded to an appointed site for recovery. The utility model has the advantages of safe production, improved labor condition and high production efficiency.

Description

The steel rope automatic decoupling device

The utility model relates to a kind of auxiliary device of using, particularly a kind of load hook steel rope automatic decoupling device.

At present, the rope that general load hook is manually suspension hook takes off, automatic decoupling device of the prior art generally can only an auto-separating steel rope, for example Chinese patent application CN2251550Y discloses a kind of " unhook device automatically ", form by hook body, driving lever and torsion spring etc., it is to rely on spring that steel rope is once ejected, and the eye splice of steel rope one end can not be stayed on the crane hook.In practical operation, in order not make the operating personnel enter the hazardous location, need take off steel rope automatically, but steel rope can not once break off relations, particularly for the bigger goods of weight, after need steel rope being extracted out from the goods bottom by elevator machinery, arrive the appointed place and take off steel rope other end eye splice again.

The purpose of this utility model is to obtain a kind of steel rope automatic decoupling device, can divide successively the two ends of steel rope to break off relations for twice.

For achieving the above object, the technical solution that the utility model proposes is:

A kind of steel rope automatic decoupling device, it comprises the shift fork that is connected with suspension hook 8, and shift fork has actuating device, and shift fork is made up of preceding shift fork 10 and back shift fork 9, and fixing angle is arranged between two shift forks, and shift fork has retracing spring.

Adjustable included angle joint between two shift forks.

A knuckle is arranged on the shift fork.

There is steel rope anti-drop rod 11 in shift fork 10 outsides before the shift fork.

Fig. 1 is the utility model steel rope automatic decoupling device reference position structural representation.

Fig. 2 is the scheme drawing of trip mechanism position when transfering to steel rope one end.

Fig. 3 is the scheme drawing of trip mechanism position when transfering to other end steel rope.

Fig. 4 is the structural representation of preceding shift fork.

Fig. 5 is the structural representation of back shift fork.

Below in conjunction with Figure of description the utility model is done and to be described in further detail:

Referring to Fig. 1, wherein 1 is hanging beam, 2 is the hanging beam jam nut, 3 is bearing pin, 4 is slip ring, the utility model is successively deviate from the eye splice of steel cable at twice in order to realize from suspension hook, adopt motor 5 shift forks, after speed reduction gearing 6 speed changes, drive a pair of (front and back) shift fork 9,10, shifting fork bar is divided into two sections, and there is a knuckle centre, and shift fork the 9, the 10th is fixed on the axle drive shaft, 7 is baffle plate, 8 is suspension hook, and the outside of preceding shift fork 9 is a steel rope anti-drop rod 11, can prevent the steel rope slippage in the handling process.

Between the shift fork 9,10 of the present utility model fixing angle is arranged, referring to Fig. 4,5, back shift fork 9 is fixed on the axle drive shaft by its axle sleeve sheet 17, on the back declutch shift shaft nest plate 17 positioning groove 18 is arranged; Preceding shift fork 10 is by 13 location of the plug on the locating dowel pin 14 at its rear portion, pull out locating dowel pin plug 13, preceding shift fork can freely rotate, be convenient to hang up steel rope, put down preceding shift fork, in the positioning groove after the locating dowel pin plug slips into voluntarily on the shift fork, do not need artificial contraposition, 15 is retracing spring, and 16 are the locating dowel pin handle.The angle between two shift forks can be finely tuned in the position of locating dowel pin on the shift fork 10 before moving.

The using method of this device is: earlier the locating dowel pin plug 13 on the preceding shift fork is extracted, (see figure 4), preceding shift fork can freely rotate in 100 ° of scopes, shift fork is put into first steel rope before lifting this moment, in the positioning groove after plug inserts automatically on the shift fork before putting down on the shift fork, put into second steel rope (see figure 1) then, the hook finish after, with the goods handling to the destination, the operating electrical machines switch, preceding shift fork is transferred to the suspension hook (see figure 2) with first steel rope, rise suspension hook, steel rope is extracted out under goods, run to steel rope and reclaim ground, operating switch once more, back shift fork is transferred to the suspension hook (see figure 3) with the steel rope other end.

Compared with prior art, the automatic unhooking device for wirerope that the utility model obtains can After finishing the lifting process and unloading goods, operating personnel needn't enter the deathtrap and shirk goods After thing, this device shirk earlier steel wire rope one end automatically, utilize hoisting machinery with steel wire rope from goods Extract out under the thing, more whole steel wire rope shirked to the appointed place, be convenient to the recovery of steel wire rope, And shift fork can automatically reset; This device also comprises the anticreep shank, can prevent that steel wire rope from hanging up after Do not break off relations. Can realize safety in production, improve working conditions, enhance productivity. It is suitable for In steel, timber, bag cargo etc., can be widely used in station, harbour, warehouse, mine Reach the dangerous situations such as forest farm.
