Description

A kind of hanging type variable-force spring hanger

Technical field

The present invention relates to suspension bracket technical field, more particularly to a kind of hanging type variable-force spring hanger.

Background technology

Variable-force spring hanger（Also referred to as variable spring support hanging frame, bullet are hung）The power conduit that is mainly used in having vertical displacement or The supporting of equipment.Because it relies primarily on spring force to support load, therefore it is only suitable for being used in the less occasion of vertical displacement.Become Power spring support hanging frame is built with cylindrically coiled spring, and while carrying, it adapts to the thermal walking of pipeline or equipment, can also inhale The vibration in closed tube road, damping effect can be played simultaneously, plus it than constant supporting spring hanger economy, therefore allow in Stress calculation In the case of, it is designed personnel and widely uses.

At present, the spring of existing variable-force spring hanger is set in outside suspension rod, and in repair and replacement, spring takes Go out that work is complex cumbersome, influence whether the pipeline of suspention, in addition, center platen in up and down motion can and outer tube inner wall produce Friction, influences operating accuracy.

The content of the invention

To solve the above problems, the invention discloses a kind of hanging type variable-force spring hanger.

In order to reach object above, the present invention provides following technical scheme：

A kind of hanging type variable-force spring hanger, it is characterised in that：Including the outer barrel being vertically arranged, set at the top of the outer barrel There is the top plate with boatswain chair, bottom is provided with bottom plate, coordinates in outer barrel and be provided with center platen component, medium pressure board component includes upper The diameter of the spacing plectane of lower setting and middle pressure plectane, the spacing plectane and middle pressure plectane is respectively less than outer barrel internal diameter, and spacing Connected in the middle part of the bottom surface of plectane with the middle part of middle pressure plectane top surface by connecting pole, in the side circumferential direction of the spacing plectane Arc groove is furnished with, coordinates in the arc groove and ball is installed, and on the inside of ball contact outer barrel, medium pressure plectane bottom surface Middle part is connected with suspension rod, and at least three first spacing collars are evenly equipped with bottom surface, and the suspension rod upper end is fixed with middle pressure plectane Connection, lower end through in the middle part of bottom plate and being connected with flower basket bolt, the plate top surface be evenly equipped with the first spacing collar position and The second corresponding spacing collar of quantity, the bullet corresponding with the first spacing collar quantity is provided between medium pressure plectane and bottom plate Spring, the spring upper end are set in outside the first spacing collar, and lower end is arranged in the second spacing collar, and the outer barrel side is provided with Rectangular opening, be hinged in the rectangular opening be combined with it is matched renovate, it is described to renovate in circular arc tabular.

Further, in addition to alignment pin.

Further, at least two alignment pins being adapted with alignment pin are evenly equipped with the circumferential direction of the outer barrel upper end Hole.

Further, the height of the connecting pole is not less than the diameter of alignment pin.

Further, the external diameter of first spacing collar is identical with spring inside diameter.

Further, the internal diameter of second spacing collar is identical with spring outer diameter.

Compared with prior art, the beneficial effects of the present invention are：It is distributed on using by spring between middle pressure plectane and bottom plate Suspension rod around mode, on the one hand, facilitating attendant is not influenceing suspension pipe and is being changed without the feelings of overall suspension bracket Under condition, spring is overhauled and changed, it is convenient and swift, reduce and safeguard replacement cost, on the other hand, can be according to actual suspention Load needed for pipeline, it is simple and practical to select the spring of varying number and specification, it is applied widely；Employ center platen group Part, on the one hand, by the ball on limiting plate, it ensure that the stable motion up and down of middle pressure plectane, and by original face and face Friction replaces with a little friction with face, reduces frictional force, improves operating accuracy, on the other hand, moreover it is possible to facilitate alignment pin to determine Plectane is pressed in position, so as to the position of positioning suspender, facilitates the suspention and Maintenance and Repair work of pipeline.
