Abstract
The utility model discloses an anti-shedding hook. The anti-shedding hook comprises a hook body and a tongue piece, wherein a rotating base is welded on an opening in the middle of the hook body, and a pull rod is welded at the rear end of the tongue piece and is sleeved outside the hook body, a sleeve is welded at the top end of the pull rod, and the sleeve and the rotating base are articulated through a rotating shaft. The anti-shedding hook provided by the utility model has the advantages that the pull rod is additionally arranged on the rear end of the tongue piece of the traditional hook, a lever principle is utilized, the pull rod with the length and the weight greater than those of the tongue piece can effectively drive the tongue piece to adjoin to to the interior of the hook, the limitation is guaranteed, even if the tongue piece transforms, the tongue piece is kept to effectively fit the hook because of the pressing of the pull rod, and the condition that the limiting function is weakened due to the deformation of the tail end of the tongue piece is prevented; meanwhile, the use of elastic components such as a spring is canceled, when a rope in the hook is demounted, only the pull rod needs to be pulled to enable the tongue piece to expand for a proper angle, the anti-shedding hook is convenient and rapid, and the operating efficiency is obviously improved.
Description
Technical field
The utility model relates to a kind of suspension hook, is a kind of slip-off preventing suspension hook, belongs to the design and manufacture technical field of hanging device.
Background technology
Suspension hook is modal a kind of suspender in elevator machinery.Suspension hook is often suspended on the steel rope of lifting mechanism by means of parts such as assembly pulleys, needs the object of lifting to hang on suspension hook after steel rope binding, can carry out lifting operation.At present, use more generally goat's horn suspension hook, rotatable tongue piece is installed on this kind of suspension hook, tongue piece by spring spacing by its end near suspension hook, it can play the effect that prevents that rope from coming off, prevent the come off appearance of the safety problem that causes of hoisting process generation rope, guarantee the safety of staff and equipment.
But the tongue piece on traditional suspension hook in use, the general direct rope by need lifting clashes into tongue piece makes its rotation opened with certain angle, rope just can slip in suspension hook smoothly, owing to being subject to the long-term shock of rope, and the general steel ropes that adopt of rope, tongue piece can deform after normal use a period of time; more make the tongue piece end suspension hook of can not fitting completely, the function reduction of slip-off preventing, has increased potential safety hazard, and the probability that use procedure has an accident raises.And traditional tongue piece is to come spacing by elastic partss such as springs, make tongue piece end all the time to hook direction near, though can play the object that the rope that prevents from articulating on suspension hook comes off, but can be due to the spacing of the assemblies such as spring when unloading rope effort and consuming time relatively, and then workman's labour intensity is raise, work efficiency reduces.
Utility model content
In order to solve the problems of the technologies described above, the utility model aims to provide a kind of simple in structure, life-span length, good limit effect, slip-off preventing suspension hook convenient to use.
The utility model is achieved by the following technical solution:
A suspension hook, comprises suspension hook body and tongue piece; Described suspension hook body intermediate openings place is welded with rotary seat, and described tongue piece rear end is welded with pull bar, and drag link sleeve is contained in suspension hook body exterior, and pull bar top is welded with sleeve, and sleeve and rotary seat are hinged by rotating shaft.
Described tongue piece is rectangle, and its center bottom offers arc groove towards suspension hook body one side.
Described arc groove is consistent with the shape of suspension hook body internal surface.
Described tongue piece length is 1/3～1/2 of pull bar length.
Corner dimension between described pull bar and horizontal surface is between 30 °～65 °.
Described rotating shaft is bolt, straight pin or spring cotter.
The beneficial effects of the utility model are:
Compared with prior art, the slip-off preventing suspension hook that the utility model provides, tongue piece rear end at traditional suspension hook installs pull bar additional, utilize lever principle, length and weight be all greater than tongue piece pull bar can by tongue piece effectively in suspension hook near, guarantee spacing, even and if after tongue piece distortion also the suppressing action due to pull bar keep tongue piece can effectively be adjacent to suspension hook, the limit function that prevents the distortion of tongue piece end and cause weakens, cancel the use of the elastic partss such as spring simultaneously, it is that tongue piece opens suitable angle that rope in suspension hook only need be pulled pull bar when unloading, convenient and swift, work efficiency significantly promotes.
Accompanying drawing explanation
Fig. 1 is constructional drawing of the present utility model;
In figure: 1-hanger bulk, 2-pull bar, 3-tongue piece, 4-rotary seat, 5-rotating shaft, 6-sleeve, 7-arc groove.
The specific embodiment
Below in conjunction with drawings and Examples, the technical solution of the utility model is described further, but described in desired protection domain is not limited to;
As shown in Figure 1, the slip-off preventing suspension hook that the utility model provides, comprises suspension hook body 1 and tongue piece 3; Described suspension hook body 1 intermediate openings place is welded with rotary seat 4, and described tongue piece 3 rear ends are welded with pull bar 2, and pull bar 2 is sleeved on suspension hook body 1 outside, and pull bar 2 tops are welded with sleeve 6, and sleeve 6 is hinged by rotating shaft 5 with rotary seat 4.
Described tongue piece 3 is rectangle, is convenient to processing and cost low, and its center bottom offers arc groove 7 towards a side of suspension hook body 1.
Gapless in order to be used in conjunction with suspension hook body 1, described arc groove 7 is consistent with the shape of suspension hook body 1 inside face.
Described tongue piece 3 length are 1/3～1/2 of pull bar 2 length, and it can guarantee that pull bar 2 can automatically be clamped on tongue piece 3 on suspension hook body 1 under Action of Gravity Field.
In order to guarantee enough downforce, the corner dimension between described pull bar 2 and horizontal surface is between 30 °～65 °.
In order to prevent coming off, described rotating shaft 5 is bolt, straight pin or spring cotter.
Embodiment 1: tongue piece 3 length are 1/3 of pull bar 2 length, and the angle between pull bar 2 and horizontal surface is 65 °; During use, need the steel cable (not shown) of lifting to be first placed in the top between tongue piece 3 and suspension hook body 1, steel cable moves down, lower spatula 3, left-hand revolution centered by the rotating shaft 5 that pull bar 2 and tongue piece 3 are made by bolt, makes the angle that tongue piece 3 opens can hold steel cable, and steel cable continues to be moved downward to suspension hook body 1 bottom, the dextrorotation centered by rotating shaft 5 of the pull bar 2 opening and tongue piece 3 goes to tongue piece 3 bottoms and the 1 inwall laminating of suspension hook body, can carry out lifting operation.When steel cable need be unloaded, upwards pull pull bar 2 tongue piece 3 left-hand revolutions are opened, take off steel cable, at the state that effect lower tongue 3 returns back to and fit in suspension hook body 1 inside of pull bar 2.
