Abstract
The utility model relates to the safety sliding connection wire used for transferring the electric force of various mobile apparatus and cranes which are provided with the fixing tracks. The interior of one plastic sheath only contains one guide rail, and the cross section of the guide rail is in the U shape or the H shape. The sliding connection wire is installed and matched with a quantity of special components to form a sliding connection wire system. The utility model has the advantages of big carrying current, compact structure, high rigidity, fluent curve working, small electric energy loss of the circuit, great protective property, reliable use, convenient maintenance and installation, etc.
Description
The utility model is the power transmission safety sliding contact line that is used to have the various mobile units of fixation locus, belongs to a kind of device that electric power is carried.
Along with the reach of science, the improving constantly of industrial technology level has the transmission of electricity trolley of the mobile unit, crane, vehicle etc. of fixation locus, development bring into schedule.Add the trolley that auxiliary traverse is formed by a kind of angle steel, rail, I-beam section earlier before this; another kind is that the copper cable line constitutes trolley; their shortcoming is that lead is exposed outside; there is not any safety method; extraneous conductor or human body contact circuit is short-circuited, and cause equipment breakdown and human body casualty accident.In trolley guide rail outside with plastic sheath be surrounded, in order to improve functional reliability thereafter.For example the trolley of West Germany is to include four dovetail slideways in a plastic sheath, and has and on the dolly of wheel four brushes are housed and guide rail slips.Also there are similar innovation and creation in China, promptly be that dovetail slideway is changed into rectangular guideway, in plastic sheath, include four transmission of electricity guide rails too, see utility model patent 89220107, the dovetail slideway that this utility model compares has processing and advantage easy for installation, but the both exists three big defectives, the one, because its structural qualification, the guide rail cross section is little, allows current-carrying capacity just little, some main equipments just are not suitable for, the 2nd, trolley is when the less bend of radian, and the pulley dolly of charged brush is difficult to slide in the plastic sheath inner chamber, and work is subjected to obstacle, the 3rd, the guide rail poor rigidity of trolley, the trolley rigid backbone depends on plastic sheath, because plastics exist insoluble catabiosis, has skeleton to fracture in the trolley use unavoidably, the drawing lines distortion loses protective action.
It is big that the purpose of this utility model provides a kind of current-carrying capacity, and the line electricity loss is few, service efficiency is high, and various radian bends place brush slips the trolley of no jam, good rigidly, long service life.
The utility model is achieved in that and changes the structure that an old fashioned plastic sheath contains four guide rails, adopts the new construction that only contains a guide rail in the plastic sheath.Another change is the rigid backbone of trolley is changed into metallic conductor by plastic sheath a guide rail, therefore, H shape or U-shaped are adopted in guide rail of the present utility model cross section, the replacement of this rigid backbone, its intensity will be multiplied several times, and avoided the disadvantage of ageing of plastics, trolley can be because of rigidity bad or ageing of plastics cause torsional deflection, defective such as fracture, and because guide rail, the unicity of sheath, structurally guaranteed the guide rail oad, sectional area is unrestricted, can make arbitrarily the guide rail of current-carrying capacity greatly according to the needs of equipment, the material U-shaped guide rail of guide rail adopts copper alloy, and H shape guide rail adopts aluminum alloy, the part that brush and guide rail slip, the U-shaped guide rail is at the medial surface at its body center, H shape guide rail has V-arrangement and slips groove and inlay stainless steel strip, and brush directly slips with stainless steel strip, the raising resistance to abrasion.The trolley of single guide rail is in the knee of radian maximum, and brush and guide rail slip current also unimpeded, and no jam phenomenon takes place.Its envelope guide rail of plastic sheath, only have a mouthful very little brush and slide chute, make human body and finger can not touch the guide rail electric conductor, plastics adopt engineering plastics, its insulating power are fine, and its withstand voltage 30KV/mm that reaches also forms the trolley system by some special attachment when trolley uses, they can not only guarantee that the user obtains best power supply effect, can also provide maximum facility and safety for installation, equipment operation and maintenance.
The utility model is described in further detail in conjunction with the accompanying drawings.
Accompanying drawing 1 is a U type guide rail schematic cross-section.
Accompanying drawing 2 is H type guide rail schematic cross-sections.
Accompanying drawing 3 is that trolley cooperates with special attachment and installs and uses sketch.
With reference to the accompanying drawings 1,1st, the U-shaped guide rail, the material copper alloy, extrusion molding, every length can determine that sectional area is applicable to the occasion that working current is less less than H shape guide rail according to work and transportation request.The 3rd, brush is made with the metallic material that the electric conductivity resistance to abrasion is all good, it be embedded on the current colector by it with the electric energy transmitting on the guide rail to mobile electrical devices.The 2nd, plastic sheath, its envelope guide rail also has guide rail mounting groove 4, it is current for the brush current colector is slipped on guide rail, under osculum chute 5 is arranged, plastic casing material is with engineering plastics ageing-resistant, good insulating, and it is withstand voltage to reach 30KV/mm, after being injection molded into sheath on the injection machine, guide rail is interted in the sheath, even if obtain desired trolley.With reference to the accompanying drawings 2,1st, H shape guide rail, the material aluminum alloy, manufacture method is identical with the U-shaped rail, and its sectional area is big, allows current-carrying capacity to reach more than the 2000A.The 3rd, brush, the 6th, stainless steel strip, it is V-shaped to be embedded in the V-shaped groove of guide rail, be brush and guide rail wiping partly, improve the resistance to abrasion of guide rail with its.The 2nd, plastic sheath, the same with U-shaped rail sheath, guide rail mounting groove 4 and current colector chute 5 are also arranged, with reference to the accompanying drawings 3, the 1st, trolley, the 2nd has the current colector of brush, it is had from the guidance quality energy by the universal flexible structure that connecting rod and spring are formed, and brush is close to suitable pressure on the wiping face of guide rail slides reposefully.When maintenance, under charged situation, current colector can be pulled down from trolley, the 4th, hang folder, it is used to clamp trolley, be fixed by bolts to crane girder bonded assembly steel bracket on.The 3rd, be connecting box, be used for protecting the point of connection of trolley, also can be used as the supply terminals of power supply.5 is fixed card, and it is fixed on any side of hanging folder, compresses trolley by pad, to limit its hot bearing of trend.The 6th, end cap in order to the termination of rail closure, is guaranteed safety.3,4,5,6 each part are all made with engineering plastics.
The utility model has the advantages that the plastic sheath good insulation preformance, rational in infrastructure, protection safety when having ensured trolley work allows current-carrying capacity big, and H shape guide rail reduces the Kelvin effect of alternating current, reduces line energy loss, improves service efficiency. Compact conformation uses reliably, and installation and maintenance are convenient.
