Abstract
The utility model belongs to a power supply connecting device, and particularly relates to a power supply unit for an electric flat car. The power supply unit for the electric flat car is characterized in that an electric flat car body is provided with an electric brush carrier; the electric brush carrier is provided with electric brushes; the electric brushes are connected with a wheel tread; the joint of the electric brush carrier and each electric brush is provided with a pressure spring. The power supply unit for the electric flat car, provided by the utility model, has the beneficial effects that the connection of the wheel tread and the electric flat car body is converted into electric brush connection from copper block connection, and therefore, the effective connection between the wheel tread and the electric flat car body is ensured, and the poor contact phenomenon is avoided.
Description
Technical field
It is a kind of for arrangements of electric connection, particularly a kind of electric flatcar electric supply installation that the utility model belongs to.
Background technology
Electric flatcar is the visual plant that enterprise is used for turning material, its function directly affects completing of production task, due to this electric flatcar power supply employing is the power supply of low pressure track, through step-up transformer, rectification, frequency converter, final motor, driven control, what between control housing and wheel, adopt is the power supply of side compression type charger, because design is unreasonable, adopt copper billet to connect wheel tread and level car body, often come in contact bad phenomenon, cause the frequent et out of order of equipment, have a strong impact on and produce normal operation.
Summary of the invention
Technical problem to be solved in the utility model is: how to solve and adopt copper billet to connect wheel tread and level car body, cause often coming in contact bad phenomenon.
The technical scheme that the utility model adopts is: a kind of electric flatcar electric supply installation, on level car body, there is brush holder, and on described brush holder, brush is installed, described brush connects wheel tread, and there is pressure spring described brush holder and brush junction.
The beneficial effects of the utility model are: the utility model is connected and is changed into brush and connect by the copper billet that is connected with wheel tread and level car body, has guaranteed effective connection between the two, has avoided bad contact phenomenon.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model;
Wherein, 1, level car body, 2, brush, 3, pressure spring, 4, brush holder, 5, wheel tread, 6, wheel, 7, track.
The specific embodiment
As shown in Figure 1, track connects power supply, and electric flatcar car body obtains power supply by brush holder, brush, wheel tread, track.The utility model changes former copper billet contact power supply into brush and connects power supply (connecting identical with existing motor brush), utilize motor brush rocker (motor brush rocker of existing electrical motor), make brush holder (identical with motor brush machine structure), brush is arranged on brush holder, brush connects (being connected identical with the brush of existing electrical motor) with the tread of wheel, good because of conduction, heat conduction and the lubricity of brush, and brush has certain mechanical strength and commutation ability.So brush contacts well with wheel, and is also provided with pressure spring in brush holder, so contact resistance is little, and line losses is little, conducts electricity, and goes slick.For stopping equipment generation brush in service jam and wheel hanging problem, affect equipment operation, brush holder has been installed two row's brushes, stops the problem of electric supply installation dead electricity, has thoroughly solved the breakdown of equipment causing because of bad contact.
Claims (1)
1. an electric flatcar electric supply installation, is characterized in that: on level car body, have brush holder, on described brush holder, brush is installed, described brush connects wheel tread, and there is pressure spring described brush holder and brush junction.
