Abstract

The utility model discloses a double-segment mousing-hook device for a crane, which solves the technical difficult problem that mechanical damage is easy to cause due to hook blocking in the operation of lifting hooks. The double-segment mousing-hook device comprises a hoop, an upper-segment bending piece and a spring, wherein one end of the upper-segment bending piece is mounted on the hoop through a pin shaft, the spring is connected with the upper-segment bending piece and fixed onto a lifting hook, and a movable lower-segment bending piece is mounted at the other end of the upper-segment bending piece. The double-segment mousing-hook device has the advantages that the structure is simple; the effects are obvious; when the mousing-hook device is used for hanging a rope sling, the upper-segment bending piece and the lower-segment bending piece are pulled open, the spring is pressed, after a heavy object is tied on the rope sling, the rope sling falls into the lifting hook under the influence of the heavy object, the bending pieces rebound to home positions, and the bending corner of the lower-segment bending piece is propped against the inner side of the hook point of the lifting hook, so that the rope sling can be prevented from falling off the lifting hook; and when the heavy object is laid down, the rope sling is picked off, all that is needed is to upward pull open the lower-segment bending piece, the rope sling can be taken out, so that convenience and quickness are achieved, mechanical damage can be avoided, and the phenomenon that the rope sling blocks the hook can be avoided.

Description

Hoisting crane double-joint type lock hook device
Technical field
The utility model relates to a kind of hoisting crane double-joint type lock hook device.
Background technology
Generally all designed the suspension hook anti-drop device on the hoisting crane at present, structure is the anchor ear of bar portion connection at suspension hook, connects a bending with bearing pin on the ear of anchor ear, and bending can be swung along bearing pin.When there was weight in rope sling system, rope sling dropped in the suspension hook, and an end of bending is against the bill inboard of suspension hook, prevented rope sling slippage in the suspension hook.The problem that this suspension hook anti-drop device exists is, when rope sling is thick, plucks rope sling and " stifled hook " phenomenon can occur, and the regular bending of pulling, form physical damage easily, the time-consuming material that takes.
The utility model content
At the defective that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of not " stifled hook ", non-damageable hoisting crane double-joint type lock hook device.
The technical solution of the utility model is as follows: hoisting crane double-joint type lock hook device, comprise anchor ear 1, on save bending 2, spring 3, last joint bending 2 one ends are installed on the anchor ear 1 by bearing pin, spring 3 connects to be gone up joint bendings 2 and also is fixed on suspension hook, on save that bending 2 other ends are equipped with can movable following joint bending 4.
The beneficial effects of the utility model are: when hanging rope sling, saving bending up and down can be pulled open simultaneously, and spring is pressed, be after weight is arranged, influenced by weight on the rope sling, rope sling drops in the suspension hook, the bending pop into position, following joint bending bent angle is against the bill inboard of suspension hook, prevents rope sling slippage in the suspension hook.After putting down weight, when winning rope sling, only need to save bending down and upwards pull open, rope sling just can be taken out, and is convenient and swift, can not cause physical damage, and rope sling can not the occur phenomenon of " blocking up hook ".
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Go up joint bending 2 one ends as shown in the figure and be installed on the anchor ear 1 by bearing pin, spring 3 connects to be gone up joint bending 2 and is fixed on suspension hook, on save that bending 2 other ends are equipped with can movable following joint bending 4.
When hanging rope sling, on save bending 2, save bending 4 down and can be pulled open simultaneously, spring 3 is pressed, be after weight is arranged, influenced by weight on the rope sling, rope sling drops in the suspension hook, the bending pop into position, following joint bending 4 bent angles are against the bill inboard of suspension hook, prevent rope sling slippage in the suspension hook.After putting down weight, when winning rope sling, only need to save bending 4 down and upwards pull open, rope sling just can be taken out, and is convenient and swift, can not cause physical damage, and rope sling can not the occur phenomenon of " blocking up hook ".
