Description

Pulley-type self-balancing hanging apparatus
Technical field
The utility model relates to a kind of hanging apparatus of crane, particularly relates to a kind of hanging apparatus for lifting thin wall cylinder-shaped flexible apparatus.
Background technology
In the process of thin wall cylinder-shaped flexible apparatus lifting, equipment is out of shape easily, distortion surpasses plastic deformation will occur after a certain amount of, and unstable failure generally need to arrange a plurality of suspension centres and reduce the moment of flexure of plane of weakness with many cranes at equipment.In addition, in lifting, an outside face at equipment arranges former and later two suspension centres usually, after equipment is vertically sling, therefore the weight of whole equipment just concentrates on these two suspension centres, and the hanger local stress is larger herein, need to take reinforcement measure to tube wall at device interior.Because just the side at equipment is provided with suspension centre, thus when being played, equipment will occur and ground off plumb situation after erecting, and then cause equipment to be difficult for the problem of installation.
The utility model content
The technical problems to be solved in the utility model provide a kind of can reduce the local stress at equipment hanger place and can be perpendicular to ground after equipment is erected by playing, be convenient to the pulley-type self-balancing hanging apparatus of its installation.
The utility model pulley-type self-balancing hanging apparatus, comprise equalizing bar, four equipment hangers, couple together by two steel ropes between equalizing bar and the equipment hanger, the upside of described equalizing bar is fixed with two upper hangers, downside is fixed with two lower hangers, described two lower hangers are captiveed joint with a fixed pulley respectively, and described two steel ropes pass respectively a fixed pulley, and the two ends of every steel rope are connected with an equipment hanger respectively.
The utility model pulley-type self-balancing hanging apparatus, wherein said equipment hanger comprise the being fastened pipe of steel rope is fixedly connected with a base with pipe one end, and the outer wall of the pipe other end is provided with ring baffle.
The utility model pulley-type self-balancing hanging apparatus, being shaped as of wherein said up and down hanger is board-like, and all is provided with a through hole on it.
The utility model pulley-type self-balancing hanging apparatus difference from prior art is that crossbeam upside of the present utility model is provided with two upper hangers, downside is provided with two lower hangers, and be connected with two fixed pulleys respectively on two lower hangers, the steel wire penetrating fixed pulley is connected with two equipment hangers that are fixed on equipment the same side, like this equipment the local stress at equipment hanger place is reduced and played at equipment can be perpendicular to ground after erecting, be convenient to install.
The base that equipment hanger in the utility model pulley-type self-balancing hanging apparatus comprises cylinder and is fixed on cylinder one end, the outer wall of the other end of cylinder is provided with a ring baffle, and this equipment hanger installing/dismounting is comparatively convenient.
The utility model is described in further detail below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is the front view of the utility model pulley-type self-balancing hanging apparatus;
Fig. 2 is the left view of the utility model pulley-type self-balancing hanging apparatus.
The specific embodiment
As shown in Figure 1, the utility model pulley-type self-balancing hanging apparatus comprises equalizing bar 2, is fixed on by four equipment hangers 6 on the hanging device 7, couple together by two steel ropes 5 between equalizing bar 2 and the equipment hanger 6, the upside of described equalizing bar 2 is fixed with two board-like upper hangers 1 near end positions, downside is fixed with two board-like lower hangers 3 near end positions, all is provided with a through hole on the hanger 1,3 up and down.Intrinsic hook on two fixed pulleys 4 passes respectively two through holes on the lower hanger 3, fixed pulley 4 just has been fixed on time hanger 3 like this, described four equipment hangers 6 are separately fixed on the both sides of equipment 7 in twos relatively, described equipment 7 is the thin wall cylinder-shaped flexible apparatus, and every steel rope 5 passes a fixed pulley 4 and its two ends are connected respectively with two equipment hangers 6 that are fixed on equipment 7 the same sides.In conjunction with Fig. 2 as can be known, described equipment hanger 6 comprise the being fastened pipe of steel rope 5 is fixedly connected with a base with pipe one end, and the outer wall of the pipe other end is provided with ring baffle, can prevent steel rope 5 slippages.
As shown in Figure 2, described equalizing bar 2 is a steel pipe, and hanger 1,3 is in the same vertical plane surface and the axis of equalizing bar 2 is passed on this plane up and down.
In the process of hanging device 7, two steel ropes 5 pass respectively two equipment hangers 6 that two fixed pulleys 4 will be positioned on equipment 7 the same sides and couple together, and couple together by an equalizing bar 2 between these two fixed pulleys 4, two upper hangers 1 of equalizing bar 2 are connected with the suspension hook of crane by steel rope again.In traditional hanging device, what be connected with equalizing bar only has two equipment hangers, and the use by fixed pulley 4 has become two traditional equipment hangers into four equipment hangers 6 in the utility model, equipment hanger 6 place's local stresses are disperseed, satisfy stressed requirement, saved the expense that suspension centre is reinforced.
In the process that equipment 7 is sling gradually, owing to there is fixed pulley 4, so steel rope 5 length between fixed pulley 4 and the equipment 7 can change, so can keep all the time a suitable distance between fixed pulley 4 and the equipment 7, make cylindrical device 7 not can in vertical plane surface, rotate freely by the constraint of steel rope 5.Because the both sides of cylindrical device 7 are equipped with two equipment hangers 6 and lift by crane, thus when cylindrical device 7 played erect fully after, cylindrical shell can not occur crooked, it is vertical with the ground maintenance, so just can next install equipment 7.
If run into equipment barrel long the time, can increase another slipping tail crane, it can adopt traditional lifting mode, namely adopts the cluster lifting, and suspension centre places the rear end near cylindrical shell equipment; And main crane adopts hanging apparatus of the present utility model, and its four hangers 6 place the front end near cylindrical device 7.Then main crane is after the slipping tail crane lifts cylindrical device 7 and delivers to certain position, slipping tail crane release apparatus, and the main crane equipment that plays walks on begin hanging device to assigned address afterwards.
Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
