Description
Technical field
The present invention relates to the field tests of used for transmission line wire, relate in particular to the proving installation of compound substance plug, specifically a kind of proving installation for composite core rod illumination ageing test.
Background technology
The used for transmission line wire generally forms by the aluminum steel that is used for conduction with for the heart yearn that bears tension force.Day by day urgent along with the continuous progress of the continuous lifting of electrical network transmission capacity, material technology and energy-saving and emission-reduction demand, wire both domestic and external manufacturer has released one after another a class and has adopted the compound substance plug to replace the novel conductive wire of traditional steel core.That this type of wire has is lightweight, intensity is large, thermal expansivity is little, current-carrying capacity is large, the series of advantages of corrosion resistance and good, can extensively try out in occasions such as large capacity, large drop, heavy icing areas.But because its heart yearn has been replaced by the compound substance that is comprised of fortifying fibre and resin, therefore must examine it to form the illumination aging resisting performance of resin.
At present the examination of resin illumination aging resisting performance mainly contained two class methods: a class is the heavy natural sunning aging test, is about to sample and directly is positioned under the solar radiation condition of physical environment, behind quite long one-period, its performance is examined; Another kind of is artificial illumination ageing test, namely adopts the method for manual simulation's daylight, sample is put into the exposure experiments to light case, the exposure experiments to light of strengthening.As adopt the heavy natural sunning aging test, then because earth rotation forms rise and the landing of the sun, make sunlight can from all angles fully and relatively equably irradiation to the surface of sample, if but adopt the artificial lighting aging test, then light source and the specimen mounting in the chamber all is fixed, therefore can't make sample receive uniform irradiation, cause the compound substance plug to be not quite similar at the performance degradation of its sensitive surface and shady face after artificial lighting is aging, affect the reliability of test findings.
Summary of the invention
What the present invention will solve is the problems referred to above that prior art exists, and aims to provide a kind of solar radiation condition of energy simulating natural environment and easy to operate proving installation.
For addressing the above problem, the present invention is by the following technical solutions: the proving installation that is used for composite core rod illumination ageing test, comprise casing and case lid, it is characterized in that being provided with fluorescent tube in the described case lid, be provided with specimen mounting in the described casing, described specimen mounting comprises motor, gear train and one or more sample holder that is arranged side by side and the rotating mechanism that is arranged on the support body, and described each sample holder and rotating mechanism comprise a pair of sample clamping mechanism and spur gear that is arranged on the described casing left and right sides; Described each sample clamping mechanism comprises gland bonnet, rubber plug and central shaft; Described gland bonnet offers center sample jack, and is flexibly connected with the inner of described central shaft; Described rubber plug also offers center sample jack, and is embedded in the built-in chamber of gland bonnet and central shaft coupling part; The outer end of the central shaft of right side sample clamping mechanism is connected with described spur gear, and the spur gear of each sample holder and rotating mechanism meshes successively; The central shaft of one of them sample holder and rotating mechanism and described gear train interlock.
Proving installation for composite core rod illumination ageing test of the present invention, can make things convenient for clamping and revolution to compound substance plug sample, sample is being carried out in the irradiation sample being turned round, what make sample circumferentially can both be subject to evenly controlled irradiation, the performance that guarantees sample can decay when illumination ageing is tested equably, thereby more approaching with actual conditions, improved the reliability of test.Therefore of the present inventionly have that simple in structure, reliable transmission, clamping are convenient, rotating speed evenly and the convenient characteristics such as controlled, and can sample be increased and decreased neatly according to the size of test demand or chamber.
According to the present invention, described gland bonnet and described central shaft can be flexibly connected in the following manner: described gland bonnet is provided with inner bolt hole, cooperates with external thread on the described central shaft.
According to the present invention, described gland bonnet and described central shaft also can be flexibly connected in the following manner: offer inner bolt hole on the described central shaft, cooperate with external thread on the described gland bonnet.
As a further improvement on the present invention, described central shaft is provided with dress sample breach, and described rubber plug is clamp-oned the sample installation position by this dress sample breach.
Further improve again as of the present invention, also be provided with rolling bearing on the described central shaft, described rolling bearing places on the bearing spider, described bearing spider is arranged on the described support body, the both sides of described bearing spider seal with bearing cover, can can't be penetrated into the gear position by bearing by the interior steam of warranty test case.Adopt rolling bearing to make it to cooperate with central shaft, can reduce the rotary resistance of gear.
Further improve as of the present invention, described spur gear is connected with described central shaft by key again.
Further improve as of the present invention, described gear train is bevel gear drive or belt pulley transmission again.Every kind of kind of drive has relative merits separately, but relatively even in order to guarantee the circumferential irradiation of accepting of sample, gear-driven form is paid the utmost attention in suggestion among the present invention, because can guarantee the constant of instantaneous transmission ratio during gear drive, and belt gear and chaindriven instantaneous transmission ratio change.Adopt the gear train of gear-driven form, transmit the power of being exported by motor and change transmission direction by bevel-gear sett.The advantages such as this type of kind of drive has compact conformation, and reliability is high, easy to maintenance.Adopt the bel-drivenn gear train, by a pair of belt pulley and the belt transmission power by motor output.This type of kind of drive has the advantages such as stable drive, noise is little, motor position is relatively adjustable.In actual tests, the control methods of the kind of drive, motor type and rotating speed can be selected according to the specific design of test or chamber.
