Pulley is the important composition parts of hoisting crane, movable pulley can reach labour-saving object, but but can not change the direction of power, and fixed pulley can not be laborsaving, but the direction of power can be changed, the requirement of crane hanging component operation can be met by the combination of fixed pulley and movable pulley; Hoisting crane fixed pulley is owing to needing the direction of change power, the cornerite value of described steel rope in the course of the work to fixed pulley is not a definite value, stressed too concentrating and the derailing of steel rope is caused in order to avoid cornerite is too small, generally at the arranged outside limited location device of pulley, existing inhibiting device is generally the framework of rectangle, steel rope meeting and rectangular frame generation cliding friction in hoisting crane working process, long-term friction can cause the wearing and tearing of steel rope and the destruction of inhibiting device; Therefore a kind of deep trouth derailing fixed pulley used for electric hoist reasonable in design, esy to use, safe and reliable is provided to be significantly.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide a kind of applied widely, convenient to use, operating cost is low, the solar power Waiting Lounge of complete function.
The purpose of this utility model is achieved in that a kind of deep trouth derailing fixed pulley used for electric hoist, it comprises side plate A, the left end of described side plate A is provided with rotating shaft A, described side plate A is connected with side plate B by rotating shaft A, the right-hand member of described side plate B is provided with rotating shaft B, described side plate B is connected to side plate A by rotating shaft B, described side plate A and the middle part of side plate B are connected respectively to the lower inside of suspension bracket, the bottom of described suspension bracket is provided with axle, described axle is provided with pulley, described pulley has pulley groove.
Described side plate A, side plate B, rotating shaft A and rotating shaft B surround a rectangle.
Described side plate A and side plate B is positioned at the top of axle.
Described rotating shaft A and rotating shaft B is cylinder.
The structure of described suspension bracket is character cut in bas-relief shape.
The beneficial effects of the utility model: steel rope when the utility model adopts the inhibiting device of two side plates and two rotating shaft compositions to work to fixed pulley carries out spacing, in hoisting crane working process, when diminishing around the cornerite of the steel rope on fixed pulley to fixed pulley if wear, then can touch two rotating shafts, due to the motion of steel rope, rotating shaft can rotate, its mode that friction occurs is friction of rolling, compared to existing technology, friction force of the present utility model is less, also less to the wearing and tearing of steel rope, the safety of hoisting crane operation and the service life of steel rope can be improved, when the utility model place in operation or maintenance and inspection, lubricating oil can be installed additional in rotating shaft He on pulley, ensure steel rope and the good lubricating status of inhibiting device, the utility model has the advantage that simplicity of design is reasonable, easy to use, use cost is low, safety is high.
