Abstract

The utility model relates to an automatic tripping type lifting hook, belonging to the parts of hoisting equipment. The lifting hook mainly comprises pulling plates and a lifting hook; the upper part of the pulling plate is provided with an upper transverse shaft and the lower part thereof is provided with a lower transverse shaft; the two pulling plates are connected by the upper transverse shaft and the lower transverse shaft which are respectively fixed with the pulling plates by an upper transverse shaft nut and a lower transverse shaft nut; the lifting hook is arranged on the lower transverse shaft; and one end of the lifting hook is provided with a balance pole. The utility model is provided with the balance pole structure on the common lifting hook so as to lead the lifting hook to be capable of rotating freely on the transverse shafts; after the lifted object is in place, the load of the lifted object on the lifting hook is disappeared; and the lifting hook automatically form a moment by the gravity of the balance pole, so as to lead the lifting hook to rotate, and the lifting hook becomes an inverted hook and removes the rope, thus achieving the purpose of automatic tripping. The automatic tripping type lifting hook has simple and reliable mechanical structure and guarantees the success rate of automatic tripping.

Description

The automatic disconnecting type suspension hook

Technical field

The utility model relates to a kind of suspension hook, particularly with a kind of be goods winch to behind the destination that operating personal must not enter can automatically-unhooked suspension hook in the risk range.

Background technology

General suspension hook needs to break off relations by the manually operated mode after goods is hung the destination, and operating personal need enter comparatively dangerous work area, brings certain hidden danger to production safety.And existing automatic decoupling device more complicated all has the spring loaded that uses spring to make steel rope to break off relations, the fluid pressure type that uses hydraulic pressure, the mechanical type that also has other is arranged, because relative complex is out of order easily, can not guarantee automatically-unhooked fully.

Summary of the invention

The purpose of this utility model is to provide a kind of simple and reliable for structure, the automatic disconnecting type suspension hook that automatically-unhooked success ratio is high.

The purpose of this utility model is achieved in that a kind of automatic disconnecting type suspension hook, comprise arm-tie and suspension hook, arm-tie top is provided with transverse axis, the bottom is provided with down transverse axis, two arm-ties are connected with following transverse axis by last transverse axis, last transverse axis and following transverse axis are fixed by last transverse axis nut and following transverse axis nut and arm-tie respectively, and suspension hook is installed in down on the transverse axis, and suspension hook one end is provided with trammel beam.

The automatic disconnecting type suspension hook that the utility model provides, by on ordinary lifting hook, installing the structure of trammel beam additional, suspension hook can be rotated freely on transverse axis, when hang thing in place after, the thing load that hangs on the suspension hook disappears, suspension hook forms a moment automatically by the deadweight of trammel beam, makes the suspension hook rotation, and suspension hook becomes barb, rope is sloughed, reach automatically-unhooked purpose, this device for mechanical is simple and reliable for structure, has guaranteed automatically-unhooked success ratio.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is that the utility model is inverted the working state figure when breaking off relations.

The specific embodiment

As shown in Figure 1, a kind of automatic disconnecting type suspension hook, comprise arm-tie 1 and suspension hook 3, arm-tie 1 top is provided with transverse axis 4, the bottom is provided with down transverse axis 6, two arm-ties 1 and is connected with following transverse axis 6 by last transverse axis 4, and last transverse axis 4 and following transverse axis 6 are fixing with arm-tie 1 by last transverse axis nut 2 and following transverse axis nut 6 respectively, suspension hook 3 is installed in down on the transverse axis 6, and suspension hook 3 one ends are provided with trammel beam 7.

Principle of work of the present utility model is as follows: the last transverse axis 4 between two arm-ties 1 is connected with weight-lifting equipment, suspension hook 3 is connected by steel rope etc. with hanging thing, suspension hook 3 is identical with the ordinary lifting hook effect when hanging the thing load, when hang thing in place after, load on the suspension hook 3 disappears, because hanging axis 3 can rotate freely on following transverse axis 6, under the effect of trammel beam 7, suspension hook obtains to such an extent that moment of rotation makes suspension hook 3 rotations, makes suspension hook 3 be in inversion state, as shown in Figure 2, so just can realize automatically-unhooked.

Claims (1)

1, a kind of automatic disconnecting type suspension hook, comprise arm-tie (1) and suspension hook (3), it is characterized in that: arm-tie (1) top is provided with transverse axis (4), the bottom is provided with down transverse axis (6), two arm-ties (1) are connected with following transverse axis (6) by last transverse axis (4), last transverse axis (4) and following transverse axis (6) are fixing with arm-tie (1) by last transverse axis nut (2) and following transverse axis nut (6) respectively, and suspension hook (3) is installed in down on the transverse axis (6), and suspension hook (3) one ends are provided with trammel beam (3).
