Abstract

The special-shaped bushing pipe of change can be fitted to be made of the steel liner tube 1, solid particulate matter 2 and end cap 3.The rigidity of the steel liner tube 1 is much larger than by the amount of deflection of lining pultrusion fiberglass tubes 4, and diameter is more slightly smaller than by the internal diameter of lining fiberglass tubes, reserves the gap of filled solid particulate matter 2.1 both ends of the steel liner tube are equipped with bolt 11 and nut 12, to be connected with end cap 3.The circular groove identical with glass pipe diameter and wall thickness is machined on end cap 3, wherein an end cap is equipped with filling hole 31.It steel lining pipe outside diameter and is filled by the gap solid particulate matter 2 between 4 internal diameter of lining fiberglass tubes, solid particulate matter 2 is by the tube wall of the pressure transmission that 4 tube wall of fiberglass tubes is born to the steel liner tube 1, to offset the pressure that fiberglass tubes 4 are born in sulphurated siliastic.The rigidity of the steel liner tube and the deformability of solid particulate matter are dexterously combined together by the present invention, solve two big key technical problems of pultrusion fiberglass tubes pressure-bearing and alignment, pultrusion fiberglass tubes is enable to be widely used in manufacturing composite insulator with hollow support.

Description

The special-shaped bushing pipe of change can be fitted
Technical field
The present invention relates to electric system high pressure, super-pressure and ultra-high voltage hollow composite insulator manufacturing technology fields.
Background technology
It must be in epoxy resin fiberglass pipe in hollow combined insulator manufacturing process(Hereinafter referred to as fiberglass tubes)Liner Enter a bushing pipe, the immense pressure that glass pipe outer wall is transmitted to during bearing sulphurated siliastic umbrella cover.If not being lining into bushing pipe, then Fiberglass tubes understand pressure break surely.
Existing widely used bushing pipe is formed with the preferable seamless steel pipe Precision Machining of rigidity, outer diameter and glass bore It fits closely, this steel liner tube requirement must be without any deformation by the circularity of lining fiberglass tubes, concentricity.Therefore, it is only applicable in By the winding fiberglass tubes of turnery processing.Fiberglass tubes are wound without axial glass fibre, anti-bending strength is poor, complex production process, Waste material is more, and the chip and the waste material of two tip cut-offs that turning is got off all have no utility value, and is difficult degradation in nature, general to locate Reason method is burning or landfill.It burns and generates toxic gas pollution air, landfill destroys water source and leaves a legacy of trouble to descendants, this is wound around glass The maximum sequelae that pipe production leaves.
The bending strength of pultrusion fiberglass tubes is 3 times of identical size winding pipe, and not turnery processing in process of production, no Waste material is generated, does not also cut off the extra useless pipe in both ends.Therefore, under the conditions of equal mechanical load is born, pultrusion glass pipe diameter can 1/3 is reduced than winding pipe caliber, mitigates weight 1/3, raw material 1/3 is saved, reduces cost 1/3, be a kind of high mechanical strength, electricity The product that gas performance is good, material-saving is energy saving, environmentally protective.But pultrusion pipe is limited by production technology, when product be more than certain length, just Slight bending can occur, although bending deformation quantity is in standard GB/T/T25096-2010《Alternating voltage is higher than 1000V substations With post composite insulator-definition, test method and acceptance criterion》In allowed band, but this deformation makes pultrusion fiberglass tubes It is interior to be lining into rigidity bushing pipe.Gases at high pressure and liquid were once filled in fiberglass tubes by we, to offset fiberglass tubes silicon sulfide rubber The pressure born during glue, but find that two hang-ups cannot solve:1st, gas or liquid pressing, the time of release and speed in fiberglass tubes Rate and the time of the outer silicon rubber expanded by heating pressure of fiberglass tubes and rate are inconsistent, otherwise pultrusion fiberglass tubes is caused to be forced by external pressure It splits or is pressed within power explosion;2nd, by the use of liquid or gas as the filler between the steel liner tube and fiberglass tubes, it is impossible to curved Pultrusion pipe is straightened.Therefore, pultrusion fiberglass tubes are dfficult to apply to composite insulator with hollow support always.
The content of the invention
The present invention in view of the above-mentioned problems, be intended to provide it is a kind of be applicable to flexural deformation pultrusion fiberglass tubes fit change abnormity Bushing pipe.
The special-shaped bushing pipe of change can be fitted to be made of the steel liner tube 1, solid particulate matter 2 and end cap 3.The rigidity of the steel liner tube 1 is much larger than quilt The amount of deflection of pultrusion fiberglass tubes 4 is served as a contrast, diameter is more slightly smaller than by the internal diameter of lining fiberglass tubes, reserves the gap of filled solid particulate matter 2. 1 both ends of the steel liner tube are equipped with bolt 1-1 and nut 1-2, to be connected with end cap 3.It is machined on end cap 3 and glass pipe diameter and wall Thick identical circular groove a, wherein end cap is equipped with filling hole 3-1.Steel lining pipe outside diameter and by between 4 internal diameter of lining fiberglass tubes Gap solid particulate matter 2 is filled, and solid particulate matter 2 is by the pressure transmission that 4 tube wall of fiberglass tubes is born to the tube wall of the steel liner tube 1 On, to offset the pressure that fiberglass tubes 4 are born in sulphurated siliastic.
Solid particulate matter 2 is the fine particle with certain fluidity, and such as button, metal is husky, nonmetallic globule, non- Metal sand etc..Compare through multiple material, the stainless steel ball of a diameter of 0.3mm ~ 3mm is mixed in a certain ratio, good fluidity, filling Enter it is convenient, fill that closely knit, shrinkage is small, can be as the preferred material of solid particulate matter 2.
The special-shaped bushing pipe of change can be fitted dexterously to be combined together the rigidity of the steel liner tube and the deformability of solid particulate matter, solved Two big key technical problems of pultrusion fiberglass tubes pressure-bearing of having determined and alignment.Pultrusion fiberglass tubes is enable to be widely used in manufacturing hollow branch Column composite insulator.It is this with pultrusion fiberglass tubes(Add interior insulation auxiliary)For the composite insulator with hollow support of plug, there is machine Tool intensity height, good electric property, shock resistance are strong, save material, is light-weight, installing the advantages that convenient, low energy consumption, environmentally protective, And the post composite insulator than being manufactured with other methods reduces cost more than 30%, has broad application prospects.
Description of the drawings
Attached drawing is the structure diagram of the present invention.
Specific embodiment
Referring to the drawings, with seamless steel pipe turnery processing into outer diameter than by the appropriate smaller steel lining of lining pultrusion glass bore Pipe 1.End cap 3 is processed with steel plate, wherein an end cap is equipped with filling hole 3-1.
Pultrusion fiberglass tubes 4 with liner are placed on coalignment and are straightened, the steel liner tube 1 is inserted into, loads onto two head end covers 3, Tightening nuts 1-2.
Pultrusion fiberglass tubes are vertically erected together with coalignment, the one end for having filling hole 3-1 upward, is filled from filling hole Enter solid particulate matter 2, shake fiberglass tubes with vibrator when pouring into, make solid particulate matter 2 closely knit and be close to pultrusion fiberglass tubes 4 The outer wall of inner wall and the steel liner tube 1.Fill rear enclosed filling hole.Exist at this point, solid particulate matter 2 has just been combined into lining with the steel liner tube 1 The special-shaped bushing pipe of change is fitted in pultrusion fiberglass tubes.
The built-in fiberglass tubes 4 fitted and become special-shaped bushing pipe are taken out from coalignment, is placed in mold after sulphurated siliastic, unloads A head end cover 3 is removed, pours out solid particulate matter 2, extracts the steel liner tube 1 out.So Xun Huan can fit the special-shaped lining pipe of change and reuse.
