Abstract

The utility model provides a hoisting machine and a lifting hook thereof. The lifting hook comprises a pulley block, a hook body and a hook head, wherein the hook head comprises two separated bodies which are in bilateral symmetry; the tail ends of the two separated bodies extend upwards so as to prevent lifting tools from dropping; the upper sides of the two separated bodies are symmetrically provided with at least two lifting points. The hoisting machine and the lifting hook provided by the utility model have the advantages that multiple lifting points are arranged on the hook head, and grooves of the lifting points can be used for suspending the lifting tools such as a plurality of ropes, lifting chains or lifting belts, so that the effective positioning of the lifting tools is realized; and when more lifting points of the lifting hook are used, the superposed weight of lifted objects after being lifted can be effectively decomposed, and the stressing of single lifting tool is slight, so that the safe lifting is guaranteed, the safety is high and the lifting is stable.

Description

Elevator machinery and suspension hook thereof

Technical field

The utility model relates to engineering machinery field, particularly a kind of elevator machinery and suspension hook thereof.

Background technology

Suspension hook is the indispensable important component part of elevator machinery, and the gib head of traditional suspension hook is mostly cambered surface list hook groove, is difficult to provide the suspension centre of multiple uniform stresseds.For Large-scale Hoisting part (as the blade of the dome of nuclear power, blower fan), for Hoisting Security, conventionally require multipoint hoisting.For obtaining the suspension centre of multiple uniform stresseds, traditional way is a special hanger of design, for lifting part provides lifting operation required suspension centre, the other end of this suspender is connected with suspension hook again, though make like this needs that can meet lifting operation, but need the suspender of additional designs, not only increased cost, and wasted time and energy.

Utility model content

In view of this, the utility model is intended to propose a kind of elevator machinery and suspension hook thereof, so that multiple suspension centres to be provided, realizes the effective location of suspender, so simplify lifting operation, reduce costs.

For achieving the above object, the technical solution of the utility model is achieved in that

On the one hand, the utility model provides a kind of suspension hook of elevator machinery, comprises assembly pulley, coupler body and gib head, and described gib head comprises two the symmetrical splits in left and right, the end of described two splits upwards extends to prevent that suspender from coming off, and is symmetrically arranged with at least two suspension centres at described two split upsides.

Further, the channel form structure that described suspension centre is arc.

Further, described gib head middle part is hinged on described coupler body.

Further, described assembly pulley comprises symmetrical two groups of pulleys, and described two groups of pulleys are hinged on respectively on described coupler body.

On the other hand, the invention also discloses a kind of elevator machinery, described elevator machinery is provided with suspension hook as above.

Further, described elevator machinery comprises crawler crane, wheel crane and gauntry crane.

With respect to prior art, the utlity model has following advantage: on the gib head of the suspension hook of elevator machinery described in the utility model, be provided with multiple suspension centres, the groove of suspension centre can hang the suspenders such as many ropes, chain sling or hanging belt, realizes the effective location of suspender; When multiple suspension centres of suspension hook all use, the stack weight after lifting object lifting can obtain actv. decomposes, and single suspender is stressed less, has guaranteed Hoisting Security, safe, and lifting steadily.

The specific embodiment

It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the utility model can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.

Fig. 1 to Fig. 3 is the relevant drawings of the present embodiment, as Fig. 1, shown in Fig. 2, the suspension hook of the elevator machinery described in the present embodiment, comprise assembly pulley, coupler body 2 and gib head 3, assembly pulley comprises symmetrical two groups of pulleys 1, be hinged on respectively on coupler body 2, gib head 3 middle parts are to be also hinged on described coupler body 2, gib head 3 comprises two the symmetrical splits in left and right, the end of these two splits upwards extends to prevent that suspender 5 from coming off, be symmetrically arranged with at least two suspension centres 4 at two split upsides, these suspension centres 4 are the channel form structure of arc, in order to suspension cord, the suspender such as chain sling or hanging belt 5.

Fig. 3 is suspension hook described in the present embodiment and hangs and carry large-scale structural representation while hanging loading 6, and as shown in FIG., this hangs and in loading 6, is provided with eight suspenders 5, symmetrical hanging in two splits of gib head 3 respectively, single like this suspender 5 is stressed less, safe, and lifting steadily.In the time of other objects of lifting, can, according to the lifting requirements of lifting object, select different grooves to lift.

On the gib head 3 of the suspension hook of the elevator machinery described in the present embodiment, be provided with multiple suspension centres 4, the groove of suspension centre 4 can hang the suspenders 5 such as many ropes, chain sling or hanging belt, realizes the effective location of suspender 5; When multiple suspension centres 4 of suspension hook all use, the stack weight after lifting object lifting can obtain actv. decomposes, and single suspender 5 is stressed less, has guaranteed Hoisting Security, safe, and lifting steadily.

Except the suspension hook of above-mentioned elevator machinery, the utility model also provides a kind of elevator machinery that is provided with above-mentioned suspension hook, as crawler crane, wheel crane, gauntry crane etc., the structure of other each several part of these elevator machineries, with reference to prior art, repeats no more herein.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
