Description
Technical field
The present invention relates to a kind of spring support hanging frame, especially a kind of constant-force spring hanger belongs to heat distribution pipeline and equipment suspension and support device field.
Background technique
As everyone knows, the expansion and contraction of object can make the contact netting twine of industries such as the pipeline of industries such as electric power, oil, chemical industry and electric railway produce thermal walking.In order to guarantee that thereby this thermal walking makes pipeline, netting twine be able to proper functioning, above-mentioned industry has extensively adopted constant-force spring hanger.
Existing constant-force spring hanger mainly is made of fixed frame and the slewing frame and the spring that are hingedly mounted on the fixed frame.Wherein, the end that hangs of slewing frame is connected with the pipeline or the netting twine that need to carry, and the other end is connected with spring.When pipeline or netting twine are subjected to displacement, force slewing frame below revolution left, and the transmission by power makes the spring that is connected with it that corresponding deformation also take place, thereby by consequent acting force of the spring, according to principle of moment balance, it is little slewing frame to be propped up hang a power of hanging of end output to change, thereby guarantees that the pipeline or the netting twine that are carried can normally move.For example, the applying date is that August 10, application number in 1987 are 87207385, name is called the Chinese patent of " constant force spring hanging frame ", and the applying date is that March 12 nineteen ninety, application number are the structure that 90212001 Chinese patent " constant-force disk spring support hanger " all discloses similar principles.Though technical development has after this been made many improvement at aspects such as spring structural form, control bearing capacity direction and adjustment link are provided with, substantial variation does not take place in bearing structure.
The claimant finds in practice, because the active force that spring deformation produces is obeyed the Hooke theorem, therefore the suffered carrying active force of all loading elements of the prior art (no matter being support force or suspension force) in fact all can't keep constant, because work as slewing frame in the process of reciprocating rotating, the corresponding deformation of spring is either large or small, and Guan Lian carrying active force must vary with it.This carrying variation of force obviously is disadvantageous for the stable operation that keeps loading elements such as pipeline, netting twine.In addition, when hanging the weight design alteration of thing on the on-the-spot load force transmission element, the suspension and support design load must corresponding change, and existing constant force spring hangs support and all can't adjust the loading force of being born according to on-the-spot needs, so its adaptability is not strong, uses inconvenience.
Summary of the invention
Primary and foremost purpose of the present invention is: the problem that the bearing capacity that exists at above-mentioned prior art changes with the revolution of slewing frame, propose a kind of constant-force spring hanger that can guarantee that the bearing capacity constant magnitude is constant, thereby guarantee that loading elements such as pipeline, netting twine remain stable working state.
Further aim of the present invention is: propose the also invariable spring support hanging frame of a kind of bearing capacity direction, thereby guarantee that further loading elements such as pipeline, netting twine remain stable working state.
Further object of the present invention is: propose a kind ofly when the design alteration of bearing material weight, can adjust the constant-force spring hanger of loading force according to the Site Design needs, thereby make this product have stronger adaptability, should use more flexible.
In order to reach above-mentioned primary goal of the invention, technological scheme of the present invention is:, hang the adjustable constant-force spring hanger of the constant loading force of power and direction of displacement, mainly by fixed frame (1), load coupling (9), load force transmission element (6) and spring energy-storage spare (10) are formed, one end of described load coupling (9) is connected with spring energy-storage spare (10), comprise in addition by kinematic pair and be installed in the interior displacement plate (2) of fixed frame (1), load force transmission element (6) is housed on this displacement plate (2), and be shaped on and can keep carrying directive effect power constant profile profile (19), this curved profile (19) is connected with the other end of load coupling (9).
When loading element (18) is heated when being subjected to displacement, displacement plate moves down, the curved profile (19) of displacement plate (2) will make spring produce deformation by the load coupling, the spring deformation active force is conversely again by load coupling (9) and curved profile displacement plate (2), load force transmission element (6) acts on loading element (18), going up loading force (p2) value of hanging with load force transmission element (6) balances each other, because having the bearing capacity of maintenance direction component and hang thing, the curved profile (19) on the displacement plate (2) is subjected to the thick-and-thin characteristic of thermal walking, therefore no matter pipeline, the how displacement of loading elements such as netting twine, it is constant all to remain suffered carrying active force, thereby make pipeline, loading elements such as netting twine being in when expanding with heat and contract with cold state, can reach stable working state all the time.
In order to reach further aim of the present invention, above-mentioned, hang in the adjustable constant-force spring hanger of the constant loading force of power and direction of displacement, displacement plate (2) is installed on the fixed support (1) by sliding pair, and described load force transmission element (6) is by being hingedly mounted on the displacement plate (2).
Like this, when thermal walking takes place and causes spring deformation in loading element (18), between load force transmission element (6) and the displacement plate (2), between displacement plate (2) and the fixed support (1) and the kinematic pair between displacement plate (2) and the load force transmission element (6) with acting in conjunction, automatically regulate the position of displacement plate (2), the relative position relation that remains between load force transmission element (6) and the loading element (18) is constant, thereby keeps bearing capacity (p2) direction also invariable.
In order to reach further object of the present invention, above-mentioned, hang in the adjustable constant-force spring hanger of the constant loading force of power and direction of displacement, spring energy-storage spare (10) is by the clamping of forward and backward pressing plate, fixed plate (7,11,13) and the orientation of guide rod (8), be installed on the fixed frame (1), wherein be screwed with prestressing nut (12) between the rear fender (11) on the guide rod (8), the fixed plate (13).
Like this, when on-the-spot load force transmission element (6) is gone up a weight of hanging thing and is needed change because of design, can at the scene four prestressing nuts (12) be screwed clockwise or counterclockwise, spring is adjusted to the corresponding prestressing height with the institute of design load after changing, thereby make spring force obtain adjusting, make a power of hanging obtain corresponding change, to adapt to on-the-spot change of hanging thing weight.
Find out easily, technological scheme of the present invention is skillfully constructed, simple for structure, exploitativeness is strong, having can autobalance medium counter-force, reaches supported weight, prevents the effect of the vibration that displacement produces, and can improve the stress distribution of loading element, guarantee its normal, safe operation, prolong its working life.
The product that goes out according to this conceptual design will have more the market competitiveness than existing like product.
