Abstract
The invention relates to a small-load extended-reach spring hanger device, belonging to the technical field of transport support facilities. The device comprises an elastic element, wherein the elastic element is a volute spiral spring, an inner end of the elastic element is fixedly connected with a central spindle, and an outer end of the elastic element is fixedly connected with an outer cylinder which is supported on a rack; the spindle is fixedly connected with a volute-shaped diameter-variable wheel rotation center of which the polar diameter is changed gradually; and the major diameter of a diameter-variable wheel is fixedly connected with one end of a flexible hanging element and the other end of the flexible hanging element is wound on the diameter-variable wheel and then connected with a load end. A reasonable structure that the volute spiral spring is combined with the diameter-variable wheel organically is adopted, so the device is compact in the structure, small in the volume and small in the pretightening force of the spring, and can be extended and deformed to a high degree, thus exerting efficacies of the spring sufficiently and meeting the requirements of small-load extended-reach deformation occasions. The device is good in the manufacturing technology and controlled easily in the spring quality and can meet the requirements of actual applications.
Description
Technical field
The present invention relates to a kind of spring support hanging frame that is mainly used in electric power, oil, chemical industry, the big displacement spring of especially a kind of little load is propped up device for hoisting, belongs to the facility technology field of supporting that transports.
Background technique
Understand according to the claimant, existing constant force spring hanging frame generally adopts cylindrical helical compression spring or disk spring (its typical structure is that CN200910232475.2, name are called " self-compensating constant-force spring hanger " and application number is that CN200820031529.X, name are called the Chinese patent application document of " a kind of constant force spring hanging frame " referring to application number), so the suspension bracket volume is big, Heavy Weight, when being applied to the occasion that load is less, displacement is big, it is extremely uneconomical to adopt cylindricality spiral compression spring or disk spring to make the energy storage part.
In addition, constant-force spring hanger medi-spring precompressed amount of deformation is more than 48% of its all deformation, so the elasticity utilization efficiency of spring is very unreasonable.(single-piece weight can reach 50-200Kg for the spring in the relatively large suspension bracket, single-piece length can reach 10000mm), the shaping of itself, adjust the joint square, end face processing, shaping, heat treatment and installation etc. are difficulty comparatively all, and technical order also is difficult to the required precision that reaches desirable.
In a word, the big displacement when adopting existing constant-force spring hanger to be difficult to realize little load, even realize reluctantly, also certainly will be bulky, be difficult to practical application.
Summary of the invention
The objective of the invention is to: at the above-mentioned shortcoming of existing constant force spring hanging frame existence, a kind of not only compact structure is proposed, volume is small and exquisite, and the big displacement spring of little load that can give full play to spring usefulness is propped up device for hoisting, and load is less, the demand of the big occasion of displacement thereby satisfy.
In order to reach above purpose, the big displacement spring of little load of the present invention is propped up device for hoisting and is comprised elastic component, and described elastic component is a spiral spring, fixedlys connected with the main shaft at center in its inner, fixedlys connected with the urceolus on being supported on frame in the outer end; The scroll casing shape diameter-changing wheel gyration center of described main shaft and utmost point footpath gradual change is connected, and the place, big footpath of described diameter-changing wheel is connected with an end of flexible suspender member, links to each other with load end behind the other end coiling diameter-changing wheel of described flexible suspender member.
During use, urceolus is supported and fixed on the frame, and load end is derived from the delivery line of industries such as an electric power that hangs, oil, chemical industry.When these pipelines cause that because of factor such as expand with heat and contract with cold self-position changes, this device will compensate the change in displacement of delivery line by diameter-changing wheel, and realize that load is constant.Because the Rational structure that ingenious employing spiral spring of the present invention and diameter-changing wheel organically combine, therefore not only compact structure, volume are small and exquisite, and the pretightening force of spring is very little, can realize bigger dilatation, thereby can give full play to the usefulness of spring, satisfy the needs of little load, large deformation displacement occasion, its anufacturability is good, spring-mass is controlled easily, therefore can satisfy the needs of practical application.
One of the present invention is further perfect is, the two ends of described main shaft are connected with the two diameter-changing wheel gyration center that are positioned at the axial both sides of urceolus respectively, the place, big footpath of described two diameter-changing wheels is connected with an end of two flexible suspender members respectively, the other end of described two flexible suspender members is reeled respectively behind the corresponding diameter-changing wheel and to be connected with connecting plate both sides as load end, and the position on the axial symmetry center of described connecting plate correspondence urceolus plane is provided with suspender member.Like this can be when single assembly use, the lifting load, and make load act on the symmetry center plane of spiral spring, avoid producing one-sided moment of torsion.
What the present invention was further perfect two is, described spring props up lifting and is equipped with two, the symmetrical respectively both sides, top that are fixed on portal frame of its urceolus, its flexible suspender member is everywhere reeled respectively behind the corresponding diameter-changing wheel and to be connected the middle part support fore-set of described connecting plate and the top board of upper end thereof for four jiaos with rectangle connecting plate as load end.Can be used by two covering devices like this,, and make load act on the symmetry center plane of spiral spring, avoid producing the deflection moment of torsion in the load of top board upper support.
