Abstract
The utility model relates to a crane used in a stage comprises a manual device, a wire cable, a pulley and a lifter. The lifter consists of a foundation framework and a plurality of lift frameworks. The manual device is installed on the foundation framework. One end of a haulage rope is connected with a drum and the other end of the haulage rope is directly connected with a fixed haulage point by a fixed pulley. The fixed haulage pulley and the fixed haulage point are arranged on the foundation framework. One end of a halyard is connected with the drum and the other end of the halyard passes by the fixed haulage pulley and a fixed turning pulley and goes around a lift pulley block in sequence and is fixed on a lifting fixed point. The fixed turning pulley is arranged on the foundation framework. The lifting fixed point is arranged on the first segment of the lift framework. The lift pulley block consists of the pulleys on each segment of the lift framework. The utility model adopts the lift framework with a nested structure. The coordination motion of the whole device can be performed by the cooperation of the cable and the pulley. The stage crane has simple structure and is easy, stable, safe and reliable to be lifted up and lifted down.
Description
(1) technical field
The utility model relates to the crane of using on a kind of stage.
(2) background technology
Common stage crane adopts scissors fork structure at present, rocks easily during descending operation, uses unstable; In addition, this structure manufacturing cost height, the material that reaches identical adjustable height needs is more.
(3) summary of the invention
The utility model provides the stage crane of a kind of lifting good stability, low cost of manufacture in order to overcome shortcomings such as existing crane lifting shakiness, cost height.
For this reason, the utility model is taked following technical scheme:
A kind of stage crane, include manual setter, wire rope, pulley and lifting gear, described manual setter includes the handwheel of driven by shaking, the reel of wiring, described handwheel and reel chain drive, described lifting gear is made up of foundation framework and some joint lifting frames, described some joint lifting frames are nested in outside the foundation framework successively, and the outermost lifting frame is defined as the first segment lifting frame, and described manual setter is fixedly mounted in the described foundation framework; Described wire rope includes pull rope and halliard, corresponding traction grooved and the lifting groove that is arranged in parallel that be provided with on the described reel; Described pull rope one end is connected with reel, and the other end directly is connected on the traction fixed point through the traction fixed pulley, and described traction fixed pulley, traction fixed point are arranged on the described foundation framework; Described halliard one end is connected with reel, the other end through behind traction fixed pulley, the fixed pulley of turning back successively pile warp lifting pulley group be fixed at last on the lifting fixed point, the described fixed pulley of turning back is arranged on the described foundation framework, the lifting fixed point is arranged on the first segment lifting frame, and the lifting pulley group is made up of the pulley on every joint lifting frame.
Described lifting frame is 3 joints, is followed successively by the 3rd joint lifting frame, the second joint lifting frame, first segment lifting frame from inside to outside.
Described reel is two, symmetric arrangement; Traction grooved and lifting groove are respectively two on each reel, cooperate with the wire rope that is arranged symmetrically in the foundation framework both sides respectively.
Also be provided with stop mechanism on the described manual setter.
The utility model has the advantages that: 1, adopt the lifting frame of nested structure, by the cooperation between wire rope, the pulley, realize the interlock of whole device, simple in structure, easy to operate, lifting is nature steadily, and is safe and reliable; 2, low cost of manufacture realizes that identical adjustable height only needs 1/3rd of scissors fork structure material requested; 3, the joint number of lifting frame can be set according to actual needs, satisfies different demands, and is applied widely; 4, adopt 2 reel symmetric arrangement, cooperate with 2 pull ropes, 2 halliards respectively again on each reel, more stable lifting is effectively avoided the stuck phenomenon in the lifting process; 5, can on handwheel, add stop mechanism according to actual needs, save manpower, easy to operate.
(4) description of drawings
Fig. 1 is the utility model overall structure schematic diagram;
Fig. 2 is the utility model lateral view;
Fig. 3 is the schematic diagram after the utility model rises.
(5) specific embodiment
With reference to accompanying drawing 1-3, a kind of stage crane, include manual setter 1, wire rope, pulley and lifting gear 4, described manual setter includes the handwheel 11 of driven by shaking, the reel 12 of wiring, described handwheel and reel chain drive, described lifting gear is made up of foundation framework 41 and three joint lifting frames, and described three joint lifting frames are nested in outside the foundation framework successively, is followed successively by the 3rd joint lifting frame 42, the second joint lifting frame 43, first segment lifting frame 44 from inside to outside; Described manual setter is fixedly mounted in the described foundation framework; Described wire rope includes pull rope 21 and halliard 22, corresponding traction grooved and the lifting groove that is arranged in parallel that be provided with on the described reel; Described pull rope one end is connected with reel, and the other end directly is connected on the traction fixed point 5 through traction fixed pulley 31, and described traction fixed pulley, traction fixed point are arranged on the described foundation framework; Described halliard one end is connected with reel, the other end through behind traction fixed pulley 31, the fixed pulley 32 of turning back successively pile warp lifting pulley group be fixed at last on the lifting fixed point 6, the described fixed pulley of turning back is arranged on the described foundation framework, the lifting fixed point is arranged on the first segment lifting frame, and the lifting pulley group is made up of the pulley 33 on every joint lifting frame.Described reel is two, symmetric arrangement; Traction grooved and lifting groove are respectively two on each reel, cooperate with the wire rope that is arranged symmetrically in the foundation framework both sides respectively.Also be provided with stop mechanism on the described manual setter.
When needs rise crane, rotate handwheel, drive reel by chain drive and rotate, when reel clockwise rotates, the halliard tension, at first the first segment lifting frame rises, after the arrival of first segment lifting frame is spacing, the second joint lifting frame rises, the second joint lifting frame arrive spacing after, the 3rd joint lifting frame rises, the 3rd joint lifting frame arrive spacing after, rise action and finish, as shown in Figure 3.Simultaneously, in the rise process, along with the continuous rotation of reel, the pull rope that is wrapped in advance on the reel is constantly emitted, and to the demand of pull rope, and be that the decline of lifting frame is got ready when just in time cooperating lifting frame to rise.
When needs descend crane, rotate handwheel, reel is rotated counterclockwise, pull rope is involved in reel, and the pulling lifting frame descends, simultaneously, halliard is constantly emitted from reel, and is to the demand of halliard, simple to operation, lifting is steadily natural, safe and reliable when satisfying lifting frame and descending.
