Description
Technical field
The utility model belongs to the braking resistor of diesel locomotive, is particularly useful for the diesel locomotive overhead type braking resistor of outside corridor formula diesel locomotive.
Background technology
Existing diesel locomotive braking resistor is divided into horizontal type structure and vertical structure, and horizontal type structure adopts a side air intake, opposite side air-out.Vertical structure adopts locomotive bottom air inlet, top air-out.Original braking resistor is not suitable for outside corridor formula locomotive: because of braking resistor in when work, air outlet has high temperature, high pressure gas are discharged, particularly horizontal braking resistor side air-out mode cause hot blast directly row make to outside corridor that staff's safety is on the hazard on the corridor.And vertical braking resistor need take from locomotive underframe to the locomotive head room, limited by outside corridor locomotive inner space, also can't install.
Summary of the invention
The purpose of this utility model provides a kind of diesel locomotive overhead type braking resistor rational in infrastructure to be applicable to outside corridor formula locomotive.
The purpose of this utility model is to realize like this, diesel locomotive overhead type braking resistor, at least comprise braking resistor, motor, fan blade, framework, it is characterized in that: braking resistor is arranged in the motor both sides, braking resistor is banded lap wound structure by insulating part and framework insulation, becomes 5 ° of-30 ° of angles during installation with horizontal surface; Motor is vertical installation, and the axle body end makes progress, and fan blade is contained in motor top; The both sides of braking resistor are embedded in the locomotive partition, and with the complete match of locomotive partition external form outline line, the bottom bow beam is supported by the locomotive curb girder, makes it become the part of roof.
The lower part of described motor is in the bottom at the arc end of framework.
The bottom surface of described framework is hermetically sealed body, and motor and the hermetically sealed body connecting bridge of bottom surface are that the water proof groove adds packing seal and is connected.
Characteristics of the present utility model are:
1, utilize the 0.5 meter space mounting braking resistor in the arc roof of locomotive bottom, the complete match locomotive of its profile outer contour, lower space can be arranged other parts of locomotive, rationally utilizes the locomotive space, has solved the problem of locomotive space anxiety.
2, both sides air intake, last air-out, promptly hot blast is discharged from roof, can not threaten to staff on the outside corridor.
3, blower motor adopts exhaust ventilation, has solved the motor radiating problem.
4, this bottom of device is hermetically sealed design, and the rainwater that enters this device from the top air outlet can be discharged from the both sides ventilation inlet fully, can not impact its underpart equipment because of roof leaking.
5, provide new braking resistor mounting means for newly making locomotive from now on.
Description of drawings
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing.
Fig. 1 is the utility model structural representation.
Fig. 2 is that A among Fig. 1 is to the view structure scheme drawing.
Fig. 3 is that B among Fig. 1 is to the view structure scheme drawing.
Among the figure: 1, Inlet Network; 2, braking resistor; 3, top cover; 4, Air outlet net; 5, fan blade; 6, motor; 7, bottom motors air draught net; 8, water proof groove; 9, the arc end; 10, base cross members; 11, curb girder; 12, locomotive curb girder; 13, axle body end; 14, motor top cover; 15, the top goes out calotte; 16, lead-in wire copper bar; 17, framework; 18, insulating part; 19, locomotive partition.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, braking resistor 2 is arranged in motor 6 both sides, and braking resistor 2 is drawn by lead-in wire copper bar 16 for being in series with the banded lap wound structure of a plurality of resistance.The braking resistor 2 of the banded lap wound structure of motor 6 both sides can have independently 2-4 braking resistor 2 in a side.Braking resistor 2 is by insulating part 18 and framework 17 insulation; Become 15 ° of angles during installation with horizontal surface, or 5 ° of angles, can also be that 30 ° of angles are installed.Motor 6 is vertical installation, and axle body end 13 makes progress, and fan blade 5 is contained in motor 6 tops.Locomotive brake or do from when test load, the motor shaft rotation drives fan blade 5 and rotates, and by locomotive both sides Inlet Network 1 inspiration cold air, by the gap of banded braking resistor 2, the heat that resistance is given out is discharged in the atmosphere by Air outlet net 4.
The lower part of motor 6 framework 17 the bottom at the arc end 9, not in the air channel that Inlet Network 1 and Air outlet net 4 form.During braking resistor 2 work, motor 6 bottom blast are low, and top blast height forms negative pressure, and air by bottom motors air draught net 7 inspiration motors 6, is gone out calotte 15 and the gap that motor top cover 14 forms by the top, solved the heat dissipation problem of motor.
Be hermetically sealed design between the arc end 9 of framework 17 and curb girder 11, the base cross members 10, particularly the bottom surface connecting bridge at the motor 6 and the arc end 9 has adopted 8 designs of water proof groove, guarantees that motor 6 is water-tight with the junction at the arc end 9.Arc because of being shaped as of the arc end 9, when raining, enter the rainwater of braking resistor 2 by Air outlet net 4, can not cause ponding by Inlet Network 1 discharge smoothly.
Because of its top cover 3 is the part of locomotive header, thus when design two curb girders 11 of framework 17 are embedded in the locomotive partition 19, match partition external form outline line fully, base cross members 10 is supported by locomotive curb girder 12, makes it become the part of roof.
The above only is the schematic specific embodiment of the utility model, is not in order to limit scope of the present utility model.Any those skilled in the art, equivalent variations and the modification made under the prerequisite that does not break away from design of the present utility model and principle all should belong to the scope that the utility model is protected.
