Description

Anti-drop safety device for lifting hook

Technical Field

The utility model belongs to the technical field of hoisting equipment lifting hook safety device, specifically be a lifting hook anticreep safeties.

Background

The lifting hook is a common lifting appliance in the lifting equipment, and the safety performance of the lifting hook directly influences the use safety of the lifting equipment and the personal safety of operating personnel. The related national standard or industry standard requires that the lifting hook is provided with an anti-falling device for preventing a lifting steel wire rope from sliding out of the lifting hook, and the anti-falling device is generally formed by an anti-falling hasp and a tension spring or a torsion spring at present. The disadvantage of this form of anti-run off device is that: the frequent opening of the anti-drop hasp enables the spring to be easy to fatigue, so that the spring is out of work and needs to be maintained or replaced frequently. Especially, when the thick steel wire rope is taken, two persons are needed to operate, one person presses the anti-falling hasp, and the other person hangs the rope with two hands, so that great inconvenience is brought to use, and the use cost and unsafe factors of use are increased.

SUMMERY OF THE UTILITY MODEL

To the technical problem, the utility model provides a more durable, convenient and economic reliable lifting hook anticreep safeties.

In order to achieve the above object, the utility model adopts the following technical scheme:

an anti-drop safety device of a lifting hook is characterized by comprising a hook head, magnets and an anti-drop hasp frame, wherein one end of the anti-drop hasp frame is hinged with the neck of the hook head, and the other end of the anti-drop hasp frame is provided with two magnets; the magnets are arranged on two sides of the anti-drop buckle frame, and one end of the anti-drop buckle frame, which is provided with the magnets, can be abutted against the head of the hook head or the head of the hook head; the magnet is provided with a fixed sleeve, a rubber ring and a magnet body from outside to inside.

Further, the anti-dropping buckle frame can be a sheet structure or a frame structure, and is preferably a frame structure.

Furthermore, the radian of the anti-falling buckle frame is consistent with the radian of the inner side of the hook head.

Further, the magnets are arranged on two sides of the anti-falling buckle frame through nuts.

The utility model has the advantages that:

one of them, the utility model discloses a lifting hook anticreep safeties owing to adopted above-mentioned structure, can make anticreep buckle frame opening, closed state can both continuously keep through the magnetic force effect of magnet, and the opening makes to hang to get, wire rope is convenient, can play the effect of anticreep again during the closure, hang when getting thick wire rope alone operate can.

Secondly, a rubber ring and a fixed sleeve are added at the joint of the magnet and the anti-falling hasp, so that the impact damage to the magnet is reduced, and the service life of the magnet is prolonged; magnet passes through the nut setting on the anticreep hasp frame, makes things convenient for magnet to change.

Thirdly, the utility model discloses simple structure, convenient to use, economy is reliable again.

Wherein: the hook head 1, the hook head neck 1.1, the hook head 1.2, the magnet 2, the fixed sleeve 2.1, the rubber ring 2.2, the magnet body 2.3, the anti-drop buckle frame 3, the A are in an open and rope-taking hanging state, and the B is in a closed anti-drop state.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

As shown in fig. 1 to 3b, an anti-drop safety device for a lifting hook comprises a hook head 1, a magnet 2 and an anti-drop buckle frame 3; one end of the anti-falling buckle frame 3 is connected with the neck of the hook head 1 through a pin shaft, and the other end of the anti-falling buckle frame 3 is provided with two magnets 2; the magnets 2 are arranged on two sides of the anti-falling buckle frame 3, and one end of the anti-falling buckle frame 3, which is provided with the magnets, can abut against the hook head and neck part 1.1 or abut against the hook head and neck part 1.2.

Anticreep hasp frame 3 can be sheet structure or frame construction, preferably frame construction, and anticreep hasp frame 3 adopts frame construction, and intensity is higher, makes simply, and the cost is lower, and frame construction can also make things convenient for operating personnel to observe the condition in the gib head moreover.

Two magnet 2 passes through the nut setting on anticreep hasp frame 3, and magnet 2 is very convenient when needing to be changed like this. Magnet 2 passes through the nut setting in the both sides of anticreep hasp frame 3, and the anticreep hasp frame 3 both sides all can firmly adsorb on gib head 1 like this.

The radian of the anti-falling buckle frame 3 is consistent with the inner side radian of the hook head 1, so that the anti-falling buckle frame 3 can be more attached to the hook head 1, the occupied space is reduced, and the steel wire rope can be conveniently hung and taken.

The magnet 2 is composed of a fixed sleeve 2.1, a rubber ring 2.2 and a magnet body 2.3 from outside to inside. The rubber ring 2.2 can reduce the impact on the magnet body 2.3, and avoid the failure and damage of the magnet. Fixed cover 2.1 can fixed rubber circle 2.2 and magnet body 2.3 on the one hand, and on the other hand can completely cut off the greasy dirt on the gib head 1 and to the corrosive contamination of rubber circle 2.2, prolongs the life of rubber circle 2.2.

When the steel wire rope needs to be taken out and hung, the anti-falling buckle frame 3 is pressed towards the neck of the hook head, the anti-falling buckle frame 3 is attracted to the neck of the hook head due to magnetic force and is in a state of opening and taking out the hanging rope (as shown in A in figure 1), and the steel wire rope taking out and hanging is not influenced; the anti-dropping buckle frame 3 is pulled to the head of the hook head, and the anti-dropping buckle frame 3 is attracted to the head of the hook head due to magnetic force and is in a closed anti-dropping state (as shown in B in figure 1), thereby playing the role of anti-dropping.

Considering that the magnet is easy to damage and lose efficacy due to the impact of the steel wire rope, a rubber ring and a fixed sleeve are added at the joint of the magnet and the anti-falling hasp, so that the impact force is reduced, and the magnet is convenient to damage and replace.

The anti-drop hasp designed in this way is more durable, convenient and economic and reliable, and the on-site trial effect is good. This use is novel convenient to use, and one person only operates when hanging and get thick wire rope.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any form, and any modifications and equivalents of the technical spirit of the present invention to any simple modifications made by the above embodiments do not depart from the technical solution of the present invention, and all fall within the scope of the technical solution of the present invention.

Details not described in this specification are within the skill of the art that are well known to those skilled in the art.
