Abstract

The utility model discloses an anti-unhooking hook device of a crane. The anti-unhooking hook device comprises a hook body and an anti-unhooking device, wherein the hook body is located below the crane and used for hanging objects; the anti-unhooking device is arranged on the hook body; the anti-unhooking device comprises a lantern ring, a duck-tongue-shaped steel plate and a handle, the lantern ring is fixedly installed on the hook body through a fastener, the duck-tongue-shaped steel plate is movably installed in the middle of the fastener, and the handle is welded in the middle of one end, which is close to the fastener, of the duck-tongue-shaped steel plate. The anti-unhooking hook device can play a role in preventing a cable in a hook opening from falling out of the hook opening. Meanwhile, compared with a traditional anti-unhooking hook device, the anti-unhooking hook device is more convenient and labor-saving to operate, not easy to damage and quite suitable for being used in places where cables are frequently used for hanging objects.

Description

A kind of hoisting crane dropping-proof hook device

Technical field

The utility model relates to a kind of hoisting crane technical field, relates in particular to a kind of hoisting crane dropping-proof hook device.

Background technology

At present, the Anti-hook releasing device overwhelming majority of crane hook uses the thick steel plate of 1 mm ~ 3mm to be made into duck tongue type, uses Spring Card and micro screw this duck tongue shape steel plate to be fixed on to the neck of suspension hook.In use, rigging can directly be enclosed within on suspension hook, duck tongue type Anti-hook releasing device is under the Action of Gravity Field of rigging, rotate as rotating shaft using micro screw, opening together with forming with suspension hook, rigging enters the mouth of hook, and duck tongue type Anti-hook releasing device is under the effect of spring force, form closure with suspension hook, prevent that rigging from running out of in use.

Duck tongue type Anti-hook releasing device in use, needs operating personal to use thumb to pin steel plate when steel rope is deviate from, rigging takes out from suspension hook mouth.If suspension hook is larger, corresponding Anti-hook releasing device is also larger, when operating personal is deviate from rigging from suspension hook, pinning Anti-hook releasing device relatively requires great effort, often running at work crane hook Anti-hook releasing device uses inconvenient and fragile, and rigging, in the time taking out from suspension hook, is easily pushed down finger.

Contriver finds that the tongue shape steel plate of current Anti-hook releasing device is thinner in addition, and hand is pulled the rear distortion that easily causes; Secondly, spring in use also easily damages (generation plastic deformation), and the micro screw of fixing Anti-hook releasing device is easily distortion also.

Utility model content

Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, provide a kind of simple in structure, the life-span long, easy to operate hoisting crane dropping-proof hook device.

In order to solve above technical matters, the utility model provides a kind of hoisting crane dropping-proof hook device, comprise Anti-hook releasing device and the coupler body for hung articles, described Anti-hook releasing device is fixedly installed on described coupler body, described coupler body is positioned at hoisting crane below, and described Anti-hook releasing device comprises the collar, fastener, duck tongue shape steel plate and handle; The described collar is fixedly installed on coupler body by fastener, and described duck tongue shape steel plate is movably arranged on described fastener midway location, and described handle is welded on described duck tongue shape steel plate near described fastener one end midway location.

The technical scheme that the utility model further limits is:

Further, described duck tongue shape steel plate thickness is 2.5mm ~ 4mm.

Further, the tail end of described duck tongue shape steel plate is provided with an arc groove, and in the time that duck tongue shape steel plate withstands on suspension hook, the arc of groove and suspension hook matches, and prevents that rigging from coming off.

Further, described fastener adopts bolt.

Further, the diameter 10 ~ 16mm of described bolt screw rod, adopts thick screw rod to have the advantages such as long service life is wear-resistant.

Further, described handle adopts metallic material.

The utility model does not re-use the source of spring as the closed power of device, and employing lever principle, utilize the weight of handle self that duck tongue shape steel plate is withstood on suspension hook, in the time getting in suspension hook mouth rigging, only need gently lift with have gentle hands the handle of Anti-hook releasing device, can drive duck tongue shape steel plate to rotate, form suspension hook opening, and opening is larger, rigging just can be easy to take out.

The beneficial effects of the utility model are: this suspension hook Anti-hook releasing device can play the effect from deviating from the mouth of hook of rigging in the mouth of hook that prevents.Simultaneously more traditional suspension hook Anti-hook releasing device operation is easier to be laborsaving, and not fragile, is applicable to very much using the place that uses rigging hung articles frequent.

Fig. 2 is the utility model rigging schematic diagram of slinging;

Fig. 3 is that the utility model hangs on schematic diagram after rigging.

The specific embodiment

embodiment 1

A kind of hoisting crane dropping-proof hook device that the present embodiment provides, structure as shown in Figure 1, 2, 3, comprises and is positioned at hoisting crane below for the coupler body 6 of hung articles and is fixedly installed on the Anti-hook releasing device on coupler body 6.

Anti-hook releasing device comprises the collar 1, fastener 3, duck tongue shape steel plate 4 and metal handle 2, and the collar 1 is by the screw rod midway location that bolt 3 is fixedly mounted on coupler body 6, duck tongue shape steel plate 4 is movably arranged on bolt 3; Metal handle 2 is welded on one end midway location near screw rod 3 on duck tongue shape steel plate 4, and the tail end of duck tongue shape steel plate 4 is provided with an arc groove 5.

Duck tongue shape steel plate 4 thickness of the present embodiment are 4mm, and the screw diameter of bolt 3 is 16mm.

The present embodiment device is according to lever principle, utilize the weight of handle 2 self that duck tongue shape steel plate 4 is withstood on coupler body 6, in the time of hook taking body 6 interior rigging, only need gently lift with have gentle hands the handle 2 of Anti-hook releasing device, can drive duck tongue shape steel plate 4 to rotate, cargo hook gear opening, and opening is larger, and rigging just can be easy to take out.

In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
