Summary of the invention
The purpose of this utility model is to design a kind of current-collector of scalable contact condition, to improve the working condition of current-collector, enhances productivity.
Its main technical schemes is to connect insulator in the bottom of support, connects brush on the top of support, utilizes lead to be connected between brush and support bottom.
Described support by be positioned at top fore-stock, be positioned at the stressed connecting rod of both sides, the support strap that is positioned at the bottom is hinged, and constitutes a box frame.
Connect the brush carrier fulcrum on support top, on the brush carrier fulcrum, utilize brush carriage to connect brush.
Connect the brush carrier fulcrum on support top, the brush carriage of hinged shaped as frame on the brush carrier fulcrum utilizes two hinged conduction liner plates of brush carriage axle, brush to be connected on the conduction liner plate respectively in the both sides of brush carriage.
Between brush and conduction liner plate conductive copper plate is arranged, the upper end of lead is connected on the conductive copper plate.
In support, the two ends of the fore-stock that section takes the shape of the letter U utilize the hinged two groups of totally 4 approximately parallel stressed connecting rods of two front rod axles respectively, the other end of 4 stressed connecting rods is hinged with the support strap respectively, the lower end of lead is connected with conductive copper plate on being installed on the support strap, connects the brush carrier fulcrum on fore-stock.
On stressed connecting rod, connect the back link axle, utilize extension spring to interconnect near an end and the back link between centers of stressed connecting rod at the support strap.
On the support strap, connect adjusting bracket, on adjusting bracket, connect handle.
The utility model has the advantages that owing to utilize support that brush and insulator are interconnected, thereby can be used for rail, gently on the various railway lines such as rule, weight-normality, copper rail, aluminium alloy rail, enlarged the scope of application of current-collector; Secondly, prop up and put up shaped as frame, between the back link axle of support and support strap, utilize extension spring to interconnect, when the brush that is connected in above the support is contacted with track, under the effect of extension spring, can produce a pretightning force, guarantee that brush and track are in tight contact condition all the time, improve its electric conductivity; The 3rd, brush utilizes the brush carriage axle to be articulated on the brush carriage, brush carriage is articulated in again on the brush carrier fulcrum, when fitting on the track under the effect of brush in extension spring, owing to the reason that is hinged, brush can be adjusted the contact angle with track automatically, makes brush and track have best contact-making surface.
