Abstract
The utility model relates to a rotary moving pulley for a stage crane, which comprises a pulley, a pulley fixed base and a sliding block. The rotary moving pulley is characterized in that a circular hole is arranged in the middle of the pulley fixed base, a groove is arranged on a side surface of the pulley fixed base on the periphery of the circular hole, a circular flange disc is embedded inside the groove and capable of rotating inside the groove, and the pulley is fixed on the flange disc. As the pulley of the rotary moving pulley is fixed on the rotatable flange disc, the pulley can automatically adjust directions of the pulley according to angles of a fixed point pulley and a single point crane to enable lifting steel wire ropes of the crane to maintain complete matching on the pulley, thereby overcoming the shortcoming that accidents occur when the lifting steel wire ropes are separated from the fixed point pulley.
Description
Technical field
The utility model belongs to a kind of stage equipment, particularly a kind of rotation mobile pulley of stage loop wheel machine.
Background technology
The top of all at present used stages is provided with an equipment work platform, on this equipment work platform, be mounted with various stage equipments, the single-lift hoisting equipment that the lifting of being exclusively used in (light of stage fixed mount) wherein arranged, because the position of single-lift hoisting equipment on the equipment work platform fixed, and the lifting point that the hoisted object that requires (as: light of stage fixed mount) sets might not be fixed, so need the equipment work platform be provided with one with a fixed point of position, the lifting point upper fixed pulley set of require, the lifting steel rope of single-lift hoisting equipment is connected on the lifting point that sets by the fixed point pulley.In order to fix the fixed point pulley easily, on the equipment work platform, also be provided with the fixed point pulley track, the fixed point pulley is moved in orbit, avoid fixing the trouble of fixed point pulley constantly.But, because the angle of the pulley on the fixed point pulley is fixed, the fixed point pulley is in moving process, its pulley is constantly changing at the angle of single-lift hoisting equipment, make the lifting steel rope of loop wheel machine on pulley, can not keep fitting like a glove, even lifting steel rope disengaging fixed point pulley is had an accident.
Summary of the invention
The pulley that the purpose of this utility model provides on a kind of pulley of fixing a point can be adjusted angle voluntarily, keeps the rotation mobile pulley of the stage loop wheel machine fit like a glove with the lifting steel rope, to overcome above-mentioned deficiency.
To achieve these goals, the utility model is made of pulley, pulley firm banking and slide block, wherein slide block is fixed on pulley firm banking both sides, can be inserted between pulley firm banking and the slide block on the fixed point pulley track on the equipment work platform, be characterized in: be provided with shape hole, a garden in the centre of pulley firm banking, pulley firm banking side at shape hole, garden periphery is provided with groove, there is a garden shape flange to be embedded in the groove, flange can rotate at groove, and pulley is fixed on the flange.
Be provided with catch gear between above-mentioned pulley firm banking and the flange.
The top of above-mentioned pulley firm banking and flange is on same plane.
Because pulley of the present utility model is fixed on the rotary flange, make that pulley can be according to the direction of the angle automatic compensation pulley of fixed point pulley and single-lift hoisting equipment, make the lifting steel rope of loop wheel machine on pulley, can keep fitting like a glove, overcome the lifting steel rope and broken away from the defective of fixing a point pulley and having an accident.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the cutaway view of Fig. 1.
Fig. 3 is the birds-eye view of Fig. 1.
Among the figure: 1-pulley track, 2-pulley firm banking, 3-flange, 4-pulley, 5-slide block, 6-catch gear.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
The utility model is made of pulley 4, pulley firm banking 2 and slide block 5, wherein slide block 5 is fixed on pulley firm banking 2 both sides, can be inserted between pulley firm banking 2 and the slide block 5 on the fixed point pulley track 1 on the equipment work platform, be provided with shape hole, a garden in the centre of pulley firm banking 2, pulley firm banking side at shape hole, garden periphery is provided with groove, there is a flange 3 to be embedded in the groove, the top of pulley firm banking 2 and flange 3 is on same plane, flange 3 can rotate at groove, and pulley 4 is fixed on the flange 3.Between pulley firm banking 2 and flange 3, be provided with catch gear 6.
Principle of work of the present utility model is: pulley 4 is fixed on movably on the pulley firm banking 2 by rotatable flange 3, has guide runner 5 that pulley 4 is moved along pulley track 1 on the pulley firm banking 2.Pulley 4 is fixed pulley 4 with catch gear 6 after moving on to the desired location.The utility model aligns pulley by rotary flange dish automatically automatically with the single-lift hoisting equipment pulley, the drift angle of elimination steel rope and pulley room.
