Abstract
The utility model discloses an electric flat car, which comprises a car body, car wheels, car wheel spindles and a transformer, wherein a brush frame fixing support is arranged under the car body, brush frames are arranged on the brush frame fixing support, and the brush frames are insulated with the brush frame fixing support. The brush frames are connected with a transformer circuit, carbon brushes are arranged on the brush frames and are contacted with the external surfaces of the car wheels. A rubber insulating sleeve is arranged between each car wheel and each car wheel spindle. Compared with the prior art, the electric flat car removes the previous conductive sliding blocks, and the wheels of the electric flat car serve as sliding rings for contacting with the carbon brushes to conduct electricity, thereby overcoming the defect of failure of the whole production process caused by failure of the conductive sliding blocks in the prior art.
Description
Technical field
The utility model relates to a kind of electric flatbed tricycle.
Background technology
At present, in cold rolling production procedure process, coil of strip changes preface and mainly relies on electric flatbed tricycle to finish, in case electric flatbed tricycle breaks down, just can't have bad luck coil of strip, thereby preface is changeed in influence.The fault of electric flatbed tricycle mainly appears at electric installation.Electric installation is a conductive slider (copper coin) that becomes vertical angle with track, contacts for flat truck by deadweight and track and realizes conduction, and conductive slider fully contacts with the track maintenance in the middle of the operational process of flat truck all the time.But in the middle of the production use of reality, be subjected to reasons such as mechanical collision owing to track, make track staggered floor up and down and defectives such as the projection that the part occurs, pit in various degree occur, damage and the feasible serious flexural deformation of adapter plate generation that conductive slider is installed can fracture because of the injustice of track when conductive slider runs to herein.If want to reinstall electric installation, just must carry out shaping to adapter plate, very near because of the car body and the ground distance of flat truck, cause adapter plate shaping work difficulty bigger, the time is long.Therefore will delay the coil of strip logistics during handling failure changes preface, the production stopping accident of part of generating units occurs, makes a big impact for the whole production flow process.
Summary of the invention
At above-mentioned prior art, the utility model provides a kind of electric flatbed tricycle.
The utility model is achieved through the following technical solutions:
A kind of electric flatbed tricycle, comprise car body, wheel, rotation shaft of wheel and voltage transformer, wherein, the car body below is provided with the brush holder fixed mount, the brush holder fixed mount is provided with brush holder, insulate between brush holder and the brush holder fixed mount, and brush holder is connected with transformer circuit, brush holder is provided with carbon brush, and carbon brush contacts with the wheel outside face; Be provided with rubber insulation sleeve between wheel and the rotation shaft of wheel.
During work, electric flatbed tricycle is placed on the track, wheel contacts with track, 36V alternating current on the track passes to carbon brush by wheel (be provided with rubber insulation sleeve between wheel and the rotation shaft of wheel, electric current just can not pass through rotation shaft of wheel like this, prevents short trouble), pass to brush holder again, be transported to then on the voltage transformer, voltage transformer becomes the 36V alternating current into the 380V alternating current again, controls the flat truck cruising.
The beneficial effects of the utility model are: fully contacted by four wheels and track and can serve as the slip-ring device use, adopt the rubber insulation sleeve pipe edge of leaving no room for manoeuvre to handle between each wheel and the rotation shaft of wheel, the brush holder fixed mount is fixed near the position the wheel, adjust the position and the distance of carbon brush and wheel, and carry out insulation processing, to prevent the fault that is short-circuited.During use, the lead that was connected on conductive slider originally is connected on the carbon brush, can realizes supply regular power flat truck.
Compared with prior art, the utility model has removed original conductive slider, contact with carbon brush and conduct electricity but serve as slip ring, cause the defective of whole production flow process paralysis owing to conductive slider breaks down thereby overcome in the prior art by the wheel of flat truck.

Fig. 2 is a running condition reference diagram of the present utility model.
Wherein, 1, car body; 2, wheel; 3, rotation shaft of wheel; 4, rubber insulation sleeve; 5, brush holder fixed mount; 6, brush holder; 7, carbon brush; 8, track.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
A kind of electric flatbed tricycle, comprise car body 1, wheel 2, rotation shaft of wheel 3 and voltage transformer, as shown in Figure 1, wherein, car body 1 below is provided with brush holder fixed mount 5, brush holder fixed mount 5 is provided with brush holder 6, insulation between brush holder 6 and the brush holder fixed mount 5, brush holder 6 are connected (do not draw among the figure, voltage transformer is conventional the setting) with transformer circuit, brush holder 6 is provided with carbon brush 7, and carbon brush 7 contacts with wheel 2 outside faces; Be provided with rubber insulation sleeve 4 between wheel 2 and the rotation shaft of wheel 3.
During work, electric flatbed tricycle is placed on the track 8, as shown in Figure 2, wheel 2 contacts with track 8, and the 36V alternating current on the track 8 (is provided with rubber insulation sleeve 4 between wheel 2 and the rotation shaft of wheel 3 by wheel 2, electric current just can not pass through rotation shaft of wheel like this, prevent short trouble) pass to carbon brush 7, pass to brush holder 6 again, be transported to then on the voltage transformer, voltage transformer becomes the 36V alternating current into the 380V alternating current again, controls the flat truck cruising.
