Detailed Description
Example (b):
as shown in fig. 1, the present embodiment provides an auxiliary device for resisting column instability of a thin-wall corrugated pipe, including a first end fixing seat 1, a middle fixing seat 2, a second end fixing seat 3, a first ear plate 4, a second ear plate 5, a third ear plate 6, a fourth ear plate 7, a first hinge rod 8, a second hinge rod 9, a first pin 10, a third hinge rod 11, a fourth hinge rod 12, a second pin 13, and a slot 14;
specifically, first end fixing base outer lane is equipped with three more than first otic placode 4, second end fixing base outer lane is equipped with three more than second otic placode 5, middle part fixing base both sides are equipped with a set of third otic placode 6 and a set of fourth otic placode 7 respectively, first otic placode 4 hub connection first hinge rod 8, third otic placode 6 hub connection second hinge rod 9, first hinge rod 8 and second hinge rod 9 are through the first round pin axle 10 of detachable connection, second otic placode 5 hub connection third hinge rod 11, fourth otic placode 7 hub connection fourth hinge rod 12, third hinge rod 11 and fourth hinge rod 12 are made through detachable second round pin axle 13 and are connected.
In this embodiment, the middle part fixing base is detachable clamp structure.
In this embodiment, there are three first ear plates, which are disposed on the outer ring of the first end fixing seat at equal intervals.
In this embodiment, the first hinge rod, the second hinge rod, the third hinge rod and the fourth hinge rod are all provided with a slotted hole 14 for reducing weight.
In this embodiment, the inner diameter of the middle fixing seat is larger than the inner diameter of the corrugated pipe to be clamped and smaller than the outer diameter of the corrugated pipe to be clamped.
In this embodiment, the first end fixing base is adapted to the end flange of the bellows to be clamped.
In this embodiment, the second end fixing seat is adapted to the end flange of the bellows to be clamped.
When the corrugated pipe is used, the original single-section corrugated pipe with a large wave number is divided into two sections of corrugated pipes with a small wave number by utilizing the upper and lower sections of hinge mechanisms, after the wave number of the single-section corrugated pipe is greatly reduced, the pressure of the corrugated pipe with the small wave number in the single section for resisting columnar instability can be greatly increased, for the whole formed by combining the upper and lower single-section corrugated pipes with the small wave number, the middle part of the whole formed by combining the upper and lower single-section corrugated pipes is blocked by using the middle fixing seat 2, three groups of hinge mechanisms are respectively used between the pipe orifice and the middle fixing seat 2 of the upper and lower single-section corrugated pipes for carrying out auxiliary pressure bearing on the combined whole corrugated pipe, under the principle that a plane and the hinge mechanisms are rigidly connected, if the middle position of the corrugated pipe has the tendency of columnar instability, the hinge mechanisms can limit the lateral movement of the middle fixing plate, as long as the strength of the hinge mechanisms is greater than the lateral force of the integral corrugated pipe with instability, the corrugated pipe is not unstable. For the moving performance of the corrugated pipe, the hinge rod is connected with the pin shaft, so that the corrugated pipe is not constrained in the moving axis direction of the corrugated pipe, namely the corrugated pipe can be freely stretched or compressed, and the friction force generated when the pin shaft rotates is very small and can be basically ignored, so that the corrugated pipe can still maintain high flexibility under a high-pressure working condition as long as the wall thickness of the corrugated pipe is sufficiently thin.
The utility model provides an idea and method of anti column unstability auxiliary device of thin wall bellows specifically realize that this technical scheme's method and approach are many, above only the utility model discloses a preferred embodiment should point out, to the ordinary technical personnel of this technical field, is not deviating from the utility model discloses under the prerequisite of principle, can also make a plurality of improvements and moist decorations, these improvements should also be regarded as with moist decorations the utility model discloses a protection scope. All the components not specified in the present embodiment can be realized by the prior art.
