Description
Technical field
The utility model belongs to hoisting crane technical field, is specifically related to a kind of sheave, particularly a kind of electric block sheave.
Background technology
Hoisting crane plays important role in commercial production and material handling, crane hanger is the important component part of hoisting crane, in the process of crane hanging component material, there is a process rising and decline in the movable pulley of hoisting crane and suspension hook, in this process, steel rope is a value changed for the size of the cornerite of movable pulley; Sometimes because stressed uneven meeting causes the steel rope of movable pulley both sides to there is a deflection, cause suspension hook horizontal direction force unbalanced, long accumulation can cause the wearing and tearing of pulley and steel rope and stress to be concentrated; Therefore, a kind of electric block sheave easy to use, that effectively can improve crane hanging component safety is provided to be very important.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provides a kind of easy to use, electric block sheave that effectively can improve crane hanging component safety.
The purpose of this utility model is achieved in that a kind of electric block sheave, it comprises housing, to the leftly on the upside of the middle part of described housing be provided with side plate A, described side plate A and horizontal direction have certain angle, described side plate A is connected with side plate B by rotating shaft A, the middle part of described rotating shaft A is provided with runner A, the middle part of described runner A is provided with groove A, to the rightly on the upside of the middle part of described housing be provided with side plate C, described side plate C and horizontal direction have certain angle, described side plate C is connected with side plate D by rotating shaft B, the middle part of described rotating shaft B is provided with runner B, the middle part of described runner B is provided with groove B, the lower end of described housing is provided with base, described Its lower side is connected with suspension hook, described suspension hook is provided with anti-dropping device, the described housing left and right sides has symmetrical notch A and notch B.
Described side plate A and the angle of horizontal direction are 45 °-90 °.
Described runner A is cylinder.
Described groove A is circular.
Described side plate C and the angle of horizontal direction are 45 °-90 °.
Described runner B is cylinder.
Described groove B is circular.
Described notch A and notch B is slotted hole or rectangular opening.
The beneficial effects of the utility model: the utility model left and right on the upside of the middle part of movable pulley housing is provided with rotating shaft respectively, by the constraint on position, can ensure that the value of hoisting crane steel rope cornerite on movable pulley when lifting material is unlikely too small, thus the power in the horizontal direction that steel rope in hoisting process is carried distributes more even; Two rotating shafts are provided with groove, and the groove on two grooves and movable pulley in same plane, thus constrains the direction of steel rope in hoisting process, avoids deflection occurs, the problems such as lifting unstability; The utility model have reasonable in design, be easy to realize, tooling cost is low, the advantage that effectively can improve the safety of crane hanging component.
Accompanying drawing explanation
