Abstract
The utility model discloses a steel rope hopping preventing structure for a duplex pulley block. The structure comprises two fixed pulleys and a housing, wherein the two fixed pulleys are arranged coaxially side by side and are close to each other, and the housing wraps the two fixed pulleys. In order to avoid steel rope hopping, the fixed pulleys are wrapped through the full-closed housing to form a relatively narrow space, so that the steel rope hopping space is blocked and a steel rope can be prevented from sliding out of the fixed pulleys. Moreover, the two fixed pulleys are close to each other, so that accidents caused when the steel rope hops and falls to the space between the two fixed pulleys can be effectively prevented. Therefore, the steel rope hopping preventing structure for the duplex pulley block can prevent the accidents when the steel rope hops from the fixed pulleys.
Description
Technical field
The utility model relates to a kind of rope skipping preventing structure of assembly pulley, is specifically related to the anti-steel cable job-hopping of a kind of duplex assembly pulley structure.
Background technology
During the crane loading weight, six branch's formula duplex assembly pulleys have been adopted.Some steelworks does not take off the plating hoisting crane, after the cast steel part, by crane in bridge type, steel part is together lifted by crane together with the part mould, is transported to other places, steel part usually can occur hit the Peril Incident that takes off chain on other weights together with the part mould.This operation not only belongs to the askew operation of hanging that skews, but also can cause that steel cable beats, and causes steel cable in pulley place's job-hopping, causes the accident.The situation of non-ferrous metallurgical plant is a little better, but when the crane loading weight moves fast, due to the impact of weight inertia, still the steel cable deflection can occur, also the job-hopping accident can occur when serious.
The utility model content
The purpose of this utility model is to provide the anti-steel cable job-hopping of a kind of duplex assembly pulley structure, when avoiding practical six branch formula duplex assembly pulley, the accident of groove skipping of steel rope while occurs.
For achieving the above object, the technical solution of the utility model is: the anti-steel cable job-hopping of duplex assembly pulley structure comprises fixed pulley and case, described fixed pulley is two, coaxial being arranged side by side, and two fixed pulleys rely closely, and described case wraps described two fixed pulleys.
When adopting technique scheme, for fear of the steel cable job-hopping, by fully enclosed case, fixed pulley is wrapped up, form a relative narrow space, blocked the space of steel cable job-hopping and can avoid steel cable to skid off from fixed pulley.Moreover, closely being close together of two fixed pulleys, can effectively preventing steel cable job-hopping and be slipped between two fixed pulleys, cause the accident.Therefore, the anti-steel cable job-hopping of the utility model duplex assembly pulley structure can avoid steel cable to job-hop from fixed pulley, has an accident.
Further, for better lifting weight, improve safety factor, described two fixed pulleys measure-alike.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the sectional structure schematic diagram of the anti-steel cable job-hopping of the utility model duplex assembly pulley structure embodiment;
Fig. 2 is the structural representation of six branch's formula duplex assembly pulleys.
The specific embodiment
As depicted in figs. 1 and 2, the anti-steel cable job-hopping of the utility model duplex assembly pulley structure comprises fixed pulley 1 and case 2, and fixed pulley 1 is two, coaxial being arranged side by side, and two fixed pulleys 1 rely closely, and case 2 wraps described two fixed pulleys 1.
For fear of the steel cable job-hopping, with fixed pulley 1 parcel, form a relative narrow space by fully enclosed case 2, block the space of steel cable job-hopping and can avoid steel cable to skid off from fixed pulley 1.Moreover, closely being close together of two fixed pulleys 1, can effectively preventing steel cable job-hopping and be slipped between two fixed pulleys 1, cause the accident.Therefore, the anti-steel cable job-hopping of the utility model duplex assembly pulley structure can avoid steel cable from fixed pulley 1 job-hopping, has an accident.
Above-described is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
Claims (2)
1. the anti-steel cable job-hopping of duplex assembly pulley structure, comprise fixed pulley and case, it is characterized in that, described fixed pulley is two, coaxial being arranged side by side, and two fixed pulleys rely closely, and described case wraps described two fixed pulleys.
2. the anti-steel cable job-hopping of duplex assembly pulley according to claim 1 structure, is characterized in that, described two fixed pulleys measure-alike.
