Abstract
The utility model relates to a sliding contact electrical device, which comprises an arc convex tooth shape guide seat is arranged on the inner wall of a square tube shape insulated tube, and the upper part of the guide seat is sheathed with a conducting track which is provided with an opening ellipse annular shape cross section. Both parts have the advantages of both rational process, mould saving, good processibility, increased mechanical strength, improved quality, and work efficiency can be enhanced about 2 times. A current collector is arranged in the insulated tube, and can move flexibly and run stable in the insulated tube by the rolling of a steel ball; the current collector is provided with an electric brush which contacts with the conducting track to conduct; a power circuit is connected with the conducting track through a power supplier, and is sent through the electric brush to a rail portable power receiver, such as a crane; the electric brush is compacted by a dual spring, which can protect good contact in operation and reliable power transmission.
Description
The utility model relates to a kind of power transmitting device of using to mobile power receiving equipment power delivery, particularly transmission of electricity and gives the power transmitting device that the orbit movable hoisting crane is used.
Existing orbit movable hoisting crane, as twin beam overhead bridge crane, gantry crane etc., power supply is powered and is realized by Sliding contact electrical equipment to hoisting crane.Sliding contact electrical equipment is made of insulated conduit, conduction machine, current colector, charger and connector.Power supply is through transmission line of electricity is connected to conductor rail in the insulated conduit by charger on, current colector is loaded in the insulated conduit, can move flexibly along conduit, and current colector is equipped with brush and conductor rail moving contact, electricity is by brush input hoisting crane, and hoisting crane drives the same with it moved further of current colector with draw bar.
Existing Sliding contact electrical equipment is a wedge angle double wedge structure owing to install the track base cross section of conductor rail on its insulated conduit inwall, is unfavorable for the extruding-out process of insulated conduit, cause capacity rating low, and double wedge place conduit wall thickness is irregular, and the extrusion molding cooling differs, and influences quality.Corresponding conductor rail cross section is dovetail furrow or rectangular aperture ring-type, all contains horn structure, therefore produces stress concentration, and easy fracture, and processing difficulties increase productive costs; Each brush on the current colector is only used a spring application, easily causes and slides center brush and conductor rail bad contact; Current colector is contained in the interior nationality of insulated conduit and helps the roller structure walking, and roller needs the particular manufacturing craft injection moulding, increases cost.All these is the weak point that the Sliding contact electrical equipment prior art exists.
The purpose of this utility model is to design a kind of Sliding contact electrical equipment, overcome the deficiencies in the prior art part, adopt the insulated conduit of no wedge angle track base and the guide rail of no horn structure, increase the brush top pressure spring in the current colector and guarantee that brush contacts well with conductor rail, and adopt steel ball to replace roller to reduce processing mold, improve processing technology by above-mentioned measure, make it to be easy to make, simplified structure improves quality, improve work efficiency, cost-cutting.
Technical solution of the present utility model is a kind of Sliding contact electrical equipment, by insulated conduit, conductor rail, current colector, charger and connector constitute, conductor rail is set on the track base of insulated conduit inwall, current colector is loaded in the insulated conduit, can move flexibly, power supply is attached to conductor rail through charger, brush in current colector is connected to the orbit movable power receiving equipment again, power receiving equipment drives synchronous with it this movement row of current colector with draw bar, the cross-sectional plane of insulated conduit inwall upper rail seat strip structure is made circular arc double wedge shape, and corresponding conductor rail cross-sectional plane is made the oval ring-type of opening; Each brush in the current colector all is equipped with two compression springs, and current colector rolls in insulated conduit and moves along conduit with steel ball.
Description of drawings is as follows:
Fig. 1 is the Sliding contact electrical equipment structural representation.
Fig. 2 is insulated conduit and track structures scheme drawing.
The utility model in conjunction with specific embodiments, further specify as follows referring to accompanying drawing, a kind of Sliding contact electrical equipment is made of insulated conduit (1), conductor rail (2), current colector (3), charger and connector, conductor rail (2) is set on the track base (4) of insulated conduit (1) inwall of square tube type, current colector (3) is loaded in the insulated conduit (1), can move flexibly, power circuit is attached to conductor rail (2) through charger, press to the orbit movable power receiving equipment, as hoisting crane (6) via the brush (5) in the current colector (3) again.Insulated conduit (1) is made with the electrical isolation high-strength engineering plastic, referring to accompanying drawing 1,2, the cross-sectional plane of the track base (4) on insulated conduit (1) inwall is made circular arc double wedge shape, on the outer wall of insulated conduit (1), track base (4) root place on the inwall, it is even in the hope of the conduit wall thickness to have a groove (7) along the catheter length direction; It is opening, oval ring-type that corresponding conductor rail (2) is made cross sectional shape with copper busbar; Two compression springs (8) are housed on each brush (5) in the current colector (3), referring to accompanying drawing 3, current colector (3) rolls in insulated conduit (1) and moves along conduit (1) with steel ball (9), current colector (3) moves with insulated conduit (1) is, adopt steel ball (9) all is housed in upper and lower guide groove and the neck guide groove, make and roll flexibly, and guarantee that current colector (3) moves steadily, hoisting crane (6) drives the same with it moved further of current colector (3) by draw bar (10).
The track base cross section that the utility model has the advantage of insulated conduit is circular arc double wedge shape, The conductor rail cross section is the oval ring-type of opening, thereby has avoided horn structure, makes technology reasonable, Save processing mold, processability is good, enhance mechanical strength, and modification quality improves work efficiency, Process velocity can improve 2 times approximately, has groove on the conduit outer wall and makes wall thickness even, processability Good, cooling is evenly shunk unanimously during extrusion molding, and outward appearance and quality are all improved. And, this The guide rail in cross section is so that the connection clamp mechanism designs simplification of conductor rail, and the current-collector brush adopts Dual spring compresses, and it is good to guarantee that brush contacts conduction with conductor rail, and transmission of electricity is reliable. Current collection The device Sliding Structures adopts steel ball to replace roller, can save mould, reduces cost, and increases collection Electrical equipment moves running stability.
