Abstract
The utility model relates to a stage single point crane with adjustable lifting point directions, which comprises a gear motor and a winding drum, wherein a steel wire rope wound on the winding drum is outputted via a fixed point pulley. The single point crane is characterized in that an angle pulley arranged on one side of a steel wire rope outputting end on the fixed point pulley is further arranged on a fixed support, the steel wire rope is connected with a required lifting point via the angle pulley, a fixed pin is arranged on the fixed support, a pin sleeve is arranged on one side of a steel wire rope inputting end on the angle pulley, and the angle pulley is fittingly connected with the fixed pin on the fixed support via the pin sleeve. As the steel wire rope of the single point crane is connected with the required lifting point via the angle pulley, directions of a lifting point can be adjusted without moving positions of the single point crane. Beside, if the steel wire rope further needs to be outputted from the position of the lifting point for fixing through a moving pulley, the angle pulley can automatically rotate to adjust angles, thereby enabling steel wire rope outputting angles of the single point crane to maintain in accordance with steel wire rope inputting angles of the moving pulley.
Description
Technical field
The utility model belongs to a kind of stage equipment, and particularly a kind of stage is with the single-lift hoisting equipment of adjustable suspension centre direction.
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 is exclusively used in lifting light of stage fixed mount is wherein arranged, present employed single-lift hoisting equipment is by reducing motor and reel, on reel, be wound with steel rope, drive the lifting of light of stage fixed mount by steel rope.There is following defective in this single-lift hoisting equipment in operational process: because steel rope is to be wrapped on the reel, make the suspension centre of single-lift hoisting equipment can produce skew (steel rope is side travel on reel), on the single-lift hoisting equipment that has, be provided with a fixed point pulley in order to address this problem.For the needs of hoisting point position, usually need the difference according to hoisting point position, and move single-lift hoisting equipment, or be installed on the hoisting point position by a mobile pulley at present, the steel rope of single-lift hoisting equipment is exported from hoisting point position by mobile pulley by the fixed point pulley again.There is the shortcoming of moving trouble in described first method; Second method is because the fixed angle of fixed point pulley for the steel rope that advances that goes out steel rope angle and mobile pulley that can make the fixed point pulley is consistent, must be rotated the direction of single-lift hoisting equipment, the same trouble of moving single-lift hoisting equipment that exists.
Summary of the invention
The purpose of this utility model provide a kind of can be under the situation of not moving single-lift hoisting equipment, can realize fixedly suspension centre, can make the steel rope angle that of fixed point pulley realize the single-lift hoisting equipment of self-align stage again, to overcome above-mentioned deficiency with adjustable suspension centre direction.
To achieve these goals, the utility model is made of reducing motor and reel, on reel, be wound with steel rope, steel rope is by the output of a fixed point pulley, be characterized in: steel rope goes out to hold a side to be provided with an angle pulley on the fixed point pulley, angle pulley is arranged on the fixed support, and steel rope is connected with required suspension centre by angle pulley.
The said fixing support is provided with a set pin, and steel rope inlet side one side is provided with a guide on the angle pulley, and angle pulley cooperates connection by guide with set pin on the fixed support.
Because steel rope of the present utility model is connected with required suspension centre by angle pulley, make the position that must not move single-lift hoisting equipment just can adjust the direction of suspension centre, in addition, steel rope is fixing from hoisting point position output by mobile pulley more if desired, angle pulley also can rotate automatically and adjust angle, and the steel rope that advances that goes out steel rope angle and mobile pulley of single-lift hoisting equipment is consistent.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the birds-eye view of Fig. 1.
Among the figure: 1-reducing motor, 2-reel, 3-steel rope, 4-fixed point pulley, 5-fixed support, 6-angle pulley, 7-inhibiting device.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
The utility model is made of reducing motor 1 and reel 2, on reel 2, be wound with steel rope 3, steel rope 3 is by fixed point pulley 4 outputs, steel rope 3 goes out to hold a side to be provided with an angle pulley 6 on fixed point pulley 4, angle pulley 6 is arranged on the fixed support 5, and steel rope 3 is connected with required suspension centre by angle pulley 6; Fixed support 5 is provided with a set pin, and steel rope inlet side one side is provided with a guide on the angle pulley 6, and angle pulley 6 cooperates connection by guide with set pin on the fixed support.
Principle of work of the present utility model is: because steel rope 3 is connected with required suspension centre by angle pulley 6, and steel rope 3 inlet sides are fixed on the fixed support 5 on the angle pulley 6, and angle pulley 6 is to be enclosed within on the fixed support 5, so the suspension centre of single-lift hoisting equipment can change through angle pulley 6, need not to move single-lift hoisting equipment; If determine hoisting point position by mobile pulley, the steel rope 3 of angle pulley 6 output need only be connected with mobile pulley and get final product, angle pulley 6 just can make the steel rope angle of advancing that steel rope angle and mobile pulley of angle pulley 6 be consistent by rotating voluntarily, need not to move single-lift hoisting equipment equally.
The outer support of the utility model single-lift hoisting equipment is provided with an inhibiting device.
The content that is not described in detail in this specification sheets belongs to this area professional and technical personnel's known prior art.
