Abstract
The utility model relates to an anti-slip clamp ring of a crane hook, which is characterized in that the anti-slip clamp ring comprises a limit clamp ring (1), a middle clamp ring (2) and a protective clamp ring (3), wherein the limit clamp ring (1) is fixedly connected with the middle clamp ring (2), and the protective clamp ring (3) is connected with the limit clamp ring (1) and the middle clamp ring (2) by the aid of bearings (4). By the aid of close connection and mutual restriction of the three clamp rings, the anti-slip clamp ring more effectively closes the crane hook, prevents a steel wire rope inside the crane hook from being separated from the crane hook, and has the advantages of simple structure, convenient installation, difficult damage and reliable use.
Description
Technical field
The utility model relates to a kind of antiskid snap ring, relates in particular to a kind of tower crane suspension hook antiskid snap ring.
Background technology
Along with the increase of construction floor, tower crane is is vertically allocated and transported the increase of load, the influence of upper air current and climatic influences, and the operation of tower crane more and more is difficult to control.Existing tower crane suspension hook, some is not provided with the anti-slip mechanism of suspension hook, the anti-slip mechanism of some suspension hook has only a snap ring, the bearing place spring that single snap ring grab plays the steel cable position-limiting action is easy to damage, the firm hawser of Suspended Cargo might cause device damage or personnel casualty accidents from landing on the suspension hook in work progress.
The utility model content
The purpose of this utility model is in the present engineering construction process, and all unhook phenomenons of tower crane suspension hook provide a kind of simple in structure, easy for installation, the tower crane suspension hook antiskid snap ring that safety factor is high.
The utility model purpose is achieved through the following technical solutions:
A kind of tower crane suspension hook antiskid snap ring is characterized in that: described antiskid snap ring comprises spacing snap ring, middle snap ring, protection snap ring; Described spacing snap ring is captiveed joint with middle snap ring, and the protection snap ring is connected with middle snap ring with spacing snap ring by bearing.
Described bearing two ends are by the fixing antiskid snap ring of nut.On the tower crane suspension hook, a whole set of snap ring can be from disassembled and assembled freely on the tower crane suspension hook by bearing fixing for described antiskid snap ring.
The spacing snap ring of captive joint and middle snap ring can only move towards the suspension hook mouth back side.
The protection snap ring can only be positive mobile towards the suspension hook mouth.
The utlity model has following advantage:
The utility model better with the sealing of tower crane suspension hook, prevents that steel rope detaches the tower crane suspension hook in the tower crane suspension hook by the mutual restriction that is closely connected of three snap rings.The utility model is simple in structure, and is easy for installation, and not fragile use is reliable.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As depicted in figs. 1 and 2, the utility model tower crane suspension hook antiskid snap ring, wherein snap ring, 3-protection snap ring, 4-bearing, 5-suspension hook in the middle of the spacing snap ring of 1-, the 2-.
Described spacing snap ring 1 is captiveed joint with middle snap ring 2, and protection snap ring 3 is connected with spacing snap ring 1, middle snap ring 2 by bearing 4.
Spacing snap ring 1, middle snap ring 2, protection snap ring 3 are fixed on the suspension hook by bearing 4.
Spacing snap ring 1, middle snap ring 2, protection snap ring 3 are closely connected and condition each other, and bearing 4 two ends are by the fixing a whole set of snap ring of nut, and a whole set of snap ring can be from disassembled and assembled freely on the tower crane suspension hook.
Fig. 3-1, Fig. 3-2 and Fig. 3-3 are use scheme drawing of the present utility model, and arrow is represented the activity direction of spacing snap ring, middle snap ring and protection snap ring.Steel cable penetrates suspension hook between middle snap ring 2 and protection snap ring 3; middle snap ring 2 forms confined space with suspension hook and skids off suspension hook to prevent lifting rope, spacing snap ring 1 as the spacing card control of middle snap ring 2 and protection snap ring 3 position of middle snap ring 2 and protection snap ring 3.Simultaneously, hang in the thing process at tower crane, spacing snap ring 1 and middle snap ring 2 are by the self gravitation balance, and snap ring 2 can not guarantee to be connected in one effectively between three snap rings with purpose suspension hook inner slide in the middle of making.
Claims (5)
