The device comprises a safety slide wire, a first current collector and a second current collector, wherein the first current collector and the second current collector are symmetrically arranged; the slide wire head of the first current collector and the slide wire head of the second current collector are symmetrically and slidably arranged on the safety slide wire, and form electric connection with the conductive bar of the safety slide wire; and the slide wire head of the first current collector and the slide wire head of the second current collector are used for providing electric energy for the screw motor and the lifting motor of the coal unloading machine simultaneously and respectively.
Description
Technical field
The utility model relates to power domain, in particular to a kind of coal-fired car unloader power transmitting device with double end current-collector.
Background technology
The power transmitting device schematic diagram that Fig. 1 is coal-fired car unloader in correlation technique; As shown in Figure 1, the coal-fired car unloader in power plant is to utilize safety slide wire 101 to supply electric power energy by the slide wire head 103 of current-collector 102 to car unloader, the environment of car unloader operation is severe, not only dust is very big, and be often overload operation while unloading, especially unload winter while freezing coal, car unloader screw motor, lifting motor frequently burn, and wherein because running overload causes the overheated loose contact of slide wire head, cause the accident of motor damage to happen occasionally.The excessive slip that also causes of loading damages, and after the overheated sparking of slip bus, forms tumor, the heavy wear current-collector, and more serious consequence even causes bus to come off, and affects the power plant coal-supply system and normally moves.
The utility model content
The utility model provides a kind of coal-fired car unloader power transmitting device with double end current-collector, in order to overcome at least one problem existed in prior art.
For achieving the above object, the utility model provides a kind of coal-fired car unloader power transmitting device with double end current-collector, this device comprises: safety slide wire, the first current-collector and the second current-collector, wherein, the first current-collector and the second current-collector are symmetrical arranged, the slide wire head symmetry of the slide wire head of the first current-collector and the second current-collector slidably is arranged on safety slide wire, form and be electrically connected to the bus of safety slide wire, the slide wire head of the slide wire head of the first current-collector and the second current-collector provides electric energy for screw motor, the lifting motor of coal-fired car unloader respectively simultaneously.
Optionally, the material of the bus of the slide wire head of the slide wire head of above-mentioned the first current-collector, the second current-collector and safety slide wire is copper.
In the above-described embodiments, change the double end current-collector into by the single head current-collector by original, form symmetrical structure, direct motion, retrograde poor performance have been eliminated, make the reliability of power transmitting device increase by one times, overload shunting coefficient of safety has also increased by one times, has avoided slide wire head because overheated loose contact causes the generation of the accident of motor damage, ensures that the power plant coal-supply system normally moves.
The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The power transmitting device schematic diagram that Fig. 1 is coal-fired car unloader in correlation technique;
The coal-fired car unloader power transmitting device schematic diagram with double end current-collector that Fig. 2 is an embodiment of the utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not paying under the creative work prerequisite the every other embodiment obtained, and all belong to the scope of the utility model protection.
The coal-fired car unloader power transmitting device schematic diagram with double end current-collector that Fig. 2 is an embodiment of the utility model.As shown in the figure, this device comprises: safety slide wire 201, the first current-collector 202 and the second current-collector 203, wherein, the first current-collector 202 and the second current-collector 203 are symmetrical arranged, slide wire head 205 symmetries of the slide wire head 204 of the first current-collector 202 and the second current-collector 203 slidably are arranged on safety slide wire 201, form and be electrically connected to the bus (not shown) of safety slide wire 201, the slide wire head 204 of the first current-collector 202 and the slide wire head 205 of the second current-collector 203 provide electric energy for screw motor, the lifting motor of coal-fired car unloader respectively simultaneously.In addition, above-mentioned power transmitting device can also comprise a support that can move up and down, and the first current-collector 202 and the second current-collector 203 are arranged on this support, so that adjusted position is set to screw motor, the lifting motor of coal-fired car unloader, provides electric energy.
Optionally, the material of the bus of the slide wire head of the slide wire head of above-mentioned the first current-collector, the second current-collector and safety slide wire is copper.
In the above-described embodiments, change the double end current-collector into by the single head current-collector by original, form symmetrical structure, direct motion, retrograde poor performance have been eliminated, make the reliability of power transmitting device increase by one times, overload shunting coefficient of safety has also increased by one times, has avoided slide wire head because overheated loose contact causes the generation of the accident of motor damage, ensures that the power plant coal-supply system normally moves.
One of ordinary skill in the art will appreciate that: accompanying drawing is the schematic diagram of an embodiment, and the module in accompanying drawing or flow process might not be that enforcement the utility model is necessary.
One of ordinary skill in the art will appreciate that: the module in the device in embodiment can be described and be distributed in the device of embodiment according to embodiment, also can carry out respective change and be arranged in the one or more devices that are different from the present embodiment.The module of above-described embodiment can be merged into a module, also can further split into a plurality of submodules.
Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although with reference to previous embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: its technical scheme that still can put down in writing previous embodiment is modified, or part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of the utility model embodiment technical scheme.
