Description

Tubular type current-collector

Technical field

The utility model relates to power supply unit technical field, especially a kind of tubular type current-collector.

Background technique

Current-collector is one of most important component in slick line system.Current-collector is that electric energy is picked up in current collection side in sliding contact line system Main device, electric energy is directly conducted to electrical appliance, to realize system by the sliding contact of collecting brush and guide rail by it Mobile power supply.Current-collector by mechanical structure tensioner and directly formed with collecting brush two parts of guide rail sliding contact.

The tensioner of mechanical structure determines the sliding contact pressure of collecting brush and guide rail and the stability of mechanism, collecting brush It is then the conductor that electric energy is picked up in guide rail sliding contact, the superiority and inferiority of its performance and conductive qualities and material structure ingredient will be straight Connect the safe operation quality for influencing whole system equipment.

Carbon brush is located at two sides in traditional current-collector, carries out sliding contact with the copper strips in slip, but in practical applications, This contact is difficult control contact and stablizes not by the effect of lateral force, therefore is often in contact bad, influences current-collector Normal use.

Utility model content

The utility model in view of the deficiencies of the prior art, proposes a kind of tubular type current-collector, copper bar in clever structure, with slip Contact performance is good.

In order to realize above-mentioned purpose of utility model, the utility model is the following technical schemes are provided: a kind of tubular type current-collector, packet Insulation crust, carbon brush, pulley and cable are included, the carbon brush is equipped with several, is separately fixed at the upper and lower of the insulation crust On surface；The insulation crust is erected on the pulley；The cable is suspended below the insulation crust, upper end and institute State carbon brush connection.

Further, the insulation crust is connected and composed by upper and lower two parts are relatively fixed.

Further, there are five the carbon brush is set, it is divided into three lower two settings.

Further, there are two the pulley is set, set up separately in the front and back end of the insulation crust.

Further, hauling block is equipped with above the pulley.

Compared with prior art, the utility model, which has the advantage that, is respectively set carbon in the upper and lower surface of insulation crust Brush, the convenient slip for being located at tubular type slip upper and lower side with copper bar match；Insulation crust is that two parts docking is constituted, convenient Disassembly and replacement carbon brush；Overall structure is ingenious, and using effect is good.

Detailed description of the invention

In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor Under, the structure that can also be shown according to these attached drawings obtains other attached drawings.

Fig. 1 is the schematic perspective view of the utility model tubular type current-collector；

Fig. 2 is the front view of Fig. 1；

Diagram label:

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than all Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise Under every other embodiment obtained, fall within the protection scope of the utility model.

It is to be appreciated that if related in the utility model embodiment directionality instruction (such as upper and lower, left and right, it is preceding, Afterwards ...), then directionality instruction is only used for explaining opposite between each component under a certain particular pose (as shown in the picture) Positional relationship, motion conditions etc., if the particular pose changes, directionality instruction is also correspondingly changed correspondingly.

It in addition, the technical solution between each embodiment can be combined with each other, but must be with ordinary skill Based on personnel can be realized, this technical side will be understood that when the combination of technical solution appearance is conflicting or cannot achieve The combination of case is not present, also not within the protection scope of the requires of the utility model.

As illustrated in fig. 1 and 2, a kind of tubular type current-collector, including insulation crust, carbon brush 3, big pulley 4 and cable 6, it is described Carbon brush 3 is equipped with several, is separately fixed in the upper and lower surface of the insulation crust；The insulation crust is erected at the big cunning On wheel 4；The cable 6 is suspended below the insulation crust, and upper end is connect with the carbon brush 3.

Insulation crust is generally insulating materials and is made, light；It is respectively provided with carbon brush 3 in the upper and lower surface of insulation crust, And insulation crust is erected on big pulley, mobile easily carbon brush 3 is contacted with copper bar in tubular type slip to be easy, and is suitable for a variety of The tubular type slip of shape, such as it is bending, linear.

Insulation crust is fixedly connected with lower casing 2 by upper casing 1 and is constituted, as shown in Figure 1, two parts are connected through screw, therefore side Just it mounts and dismounts；In engineering design, carbon number 3 can be separately fixed on two housing sections, and part is stretched out outside shell, it is internal with Cable 6 is attached.

Because carbon brush 3 is after working long hours, abrasion be it is essential, need replacing.

There are five carbon brush 3 is set, it is divided into three lower two settings, i.e., there are three upper surface is set, there are two lower surface is set；With tubular type Copper bar position is corresponding in slip, using carbon brush structure setting up and down, not will receive the stressing influence of left and right sides, therefore in arc Tubular type slip can also match use.

Big pulley 4 sets up separately in the front and back end of the insulation crust, there are two setting to facilitate insulation crust in tubular type slip Sliding.

It is equipped with hauling block-truckle 3, above big pulley 4 with the movement for drawing tubular type current-collector；Accordingly exhausted The both ends of edge shell are equipped with truckle 3.

This product is relative to traditional structure: it is changed to carbon brush structure up and down, is matched with the tubular type slip with upper and lower copper strips, The power received just becomes upper and lower, it is possible to reduce poor contact between carbon brush copper band.

The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and Retouching also should be regarded as the protection scope of the utility model.
