Description
Technical field
The utility model relates to a kind of oil field operation instrument, relates in particular to a kind of suspension hook that prevents that suspension ring from coming off.
Background technology
In the rountrip process of oil field, elevator is suspended on the suspension hook by suspension ring, elevator has been used for lower sucker rod, thereby finish the oil field rountrip, because suspension hook is opening, in the process of lifting and whereabouts, runs into collision and be easy to generate the unhook problem, cause machinery or personal injury accident, the influence safety in production.
The utility model content
In the lifting process, produce the unhook problem in order to overcome above-mentioned suspension hook, the utility model provides a kind of dropping-proof hook, this dropping-proof hook can prevent that in use suspension ring are in the process of lifting and whereabouts, running into collision breaks off relations easily, thereby machinery or personal injury accident have been avoided, and simple in structure, easy operating.
In order to overcome above-mentioned defective, the technical solution adopted in the utility model is:
Dropping-proof hook, comprise the suspension hook body, this suspension hook body is made up of upper hook body and lower hook body, it is characterized in that: described upper hook body is provided with chute, anti-drop device is installed in the chute, described anti-drop device comprises spring perch, compression spring and backing pin, the compression spring is positioned at spring perch, the compression spring links to each other with an end of backing pin, the other end side of backing pin is provided with the bayonet lock groove, is provided with compression spring and bayonet lock in the described bayonet lock groove, and the compression spring links to each other with bayonet lock, described bayonet lock is provided with the boss that protrudes from upper hook body, and described chute comprises the vertical slots of holding backing pin and the horizontal slot that holds bayonet lock.
Described lower hook body is provided with groove, and the size of this groove and the size of backing pin are complementary.
The peristome of described chute is provided with baffle plate, and the joint of described baffle plate and upper hook body is equipped with rubber seal.
The utlity model has following advantage:
1, the utility model is provided with chute at the upper hook body of suspension hook, anti-drop device is installed in the chute, described anti-drop device comprises spring perch, compression spring and backing pin, the compression spring is positioned at spring perch, the compression spring links to each other with an end of backing pin, the other end side of backing pin is provided with the bayonet lock groove, be provided with compression spring and bayonet lock in the described bayonet lock groove, the compression spring links to each other with bayonet lock, described bayonet lock is provided with the boss that protrudes from upper hook body, and described chute comprises the vertical slots of holding backing pin and the horizontal slot that holds bayonet lock.During use, press the boss that protrudes from upper hook body, this moment, bayonet lock was return in the backing pin, because the effect of compression spring, backing pin is ejected in upper hook body, and the part of opening of coupler body is blocked fully, suspension ring are closed in the coupler body, even run into collision, suspension ring can not come off in suspension hook yet, cause machinery or personal injury accident.When needing to take out suspension ring, backing pin is pushed back in the chute, this moment, a backing pin part was limited in the upper hook body owing to the effect of bayonet lock, and suspension hook is opened, and took out suspension ring and got final product, and simple to operate, owing to only increase anti-drop device, its mechanism is simple.
2, the utility model also lower hook body be provided with groove, the size of this groove and the size of backing pin are complementary, the backing pin of Dan Chuing is limited in the lower hook body like this, also backing pin can not bumped and flies even suspension ring significantly collide backing pin, safety performance is high.
3, the peristome of the utility model chute is provided with baffle plate, and the joint of described baffle plate and upper hook body is equipped with rubber seal.The purpose that baffle plate is set is to prevent that foreign material or dust that suspension hook produces in the course of the work from entering chute, wearing and tearing backing pin and anti-pin slide, influence the effect of backing pin, the interaction energy that rubber seal is set prevents that impurity such as dust from entering in the chute, simultaneously because the elastic reaction of rubber seal also makes things convenient for dismounting and the installation of anti-drop device.
