Abstract

The utility model provides an automatic unhook device, which relates to a hanging hook which can automatically demount the hanging rope of cargoes in the course of unloading. The utility model is an improved hanging hook with a shifting rod device on the basis of the existing haning hook, and is composed of a hook body, a shifting rod, a torsional spring, an earring, a rotating shaft, etc. The rotating shaft penetrates through the earring and the torsional spring, and are connected with the shifting rod. One end of the torsion spring is inserted in the insertion hole of a spring in the earring. The other end of the torsion spring supports the lower side of the shifting rod. When the hanging hook lift and carry goods, and when the goods are unloaded at the destination, the shifting rod on the hanging hook can automatically demount the hanging rope. The purposes of safety and high efficiency can be achieved.

Description

Automatic unhook device

The suspension hook that can automatically the goods lanyard be unloaded when the utility model relates to a kind of the unloading.

General suspension hook is the people and manually will hangs over rope on the suspension hook etc. and take off, and unhook device can be automatically after goods winches to the destination unloads the lanyard of lift cargo automatically.

The purpose of this utility model provides a kind of novel suspension hook, has the function that automatically the goods lanyard is unloaded.

The purpose of this utility model is achieved in that automatic unhook device is made up of hook body 1, driving lever 2, torsion spring 3, earrings 4, rotating shaft 5, locating dowel pin 7 etc.Driving lever 2 is connected by rotating shaft 5 with earrings 4, torsion spring 3 is housed in the rotating shaft 5, when locating dowel pin 7 blocks driving lever 2 and makes driving lever 2 have the work of certain predetermincd tension that makes progress, goods lanyard 6 is placed in the ab arc of driving lever 2 (as shown in Figure 1), when suspension hook hoists, the downward power of the goods that lanyard 6 is subjected to is during greater than the elastic force of the torsion spring 3 that driving lever 2 is made progress, driving lever 2 clockwise rotates, become Fig. 2 position, 6 of lanyards fall among Fig. 2 in the bc arc, goods hangs toward the purpose place from one, after arriving the purpose place goods is put down, the elastic force of torsion spring 3 overcomes the weight of lanyard and makes driving lever 2 return to position among Fig. 1, and lanyard 6 then is arranged in shown in Fig. 1 broken circle, from the bc arc, skid off suspension hook then, realize freeing automatically the function of lanyard.

The utility model is compared with existing suspension hook, can save alongshoreman's operation of unloading, and improves handling efficiency, and makes handling safety more secure.

The constructional drawing of the utility model earrings and driving lever is seen Fig. 3, among Fig. 3: 1. earrings section, 2. rotating shaft, 3. spring washer, 4. torsion spring, 5. driving lever, 6. bolt of rear end plate, 7. spring patchhole.Rotating shaft 2 is inserted from the earrings hole, inserts then in the shaft hole of driving lever, and bolt of rear end plate is fixed rotating shaft and driving lever, and torsion spring 4 one ends insert in the spring patchhole 7, and an end is held driving lever 5 downsides.The assembly relation of bolt of rear end plate and rotating shaft, driving lever is seen A-A figure.

In the Figure of description, Fig. 1 is automatic unhook device front elevation, and the cross section of lanyard is the cross section of 6 indications among the figure, the state when starting working, the lanyard cross section when the dotted line cross section among the figure will soon escape lanyard during for end-of-job automatically.Fig. 2 is the 6 residing positions, cross section of lanyard in the Under-Slung Loads process, and this moment is because the action of gravity of goods causes driving lever to become the position of Fig. 2 from the position of Fig. 1.Fig. 3 is the constructional drawing of earrings and driving lever, and spring washer 3 and earrings 1 are passed in rotating shaft 2, pass torsion spring 4 again, links to each other with driving lever 5 at last, and torsion spring 4 one ends insert in the spring patchhole 7, and an end is held driving lever 5 downsides.Bolt of rear end plate 6 is fixing with rotating shaft 2 and driving lever 5.

When installing behind the finished parts, the locating dowel pin 7 among Fig. 1 treats that driving lever installs the last pin in back and goes into.

Claims

1, a kind of automatic unhook device, form by hook body, driving lever, torsion spring, earrings, rotating shaft, locating dowel pin etc., it is characterized in that: spring washer and earrings are passed in rotating shaft, pass torsion spring again, link to each other with driving lever at last, torsion spring one end inserts spring and inserts in the hole, and an end is held driving lever 5 downsides, and bolt of rear end plate is fixed rotating shaft and driving lever, during work, the goods lanyard is depressed driving lever, and lanyard enters in the suspension hook, and goods hangs toward the purpose place from one, after goods put down, driving lever is upspring, and lanyard skids off suspension hook from driving lever, realizes freeing automatically the function of lanyard.
