Abstract
The utility model discloses a kind of detachable resistive braking ventilation shutter device, be placed on the corresponding mouth of locomotive header covering, bottom communicates with resistive braking air outlet duct, comprise shutter frame and blade of louver window assembling, bearing pin is passed through in blade of louver window assembling, welded nut and bolt shaft are arranged on the relative window frame of on shutter frame two, four angles of shutter frame are fixed with the angle seat of band centre bore, locomotive header covering is provided with the locating piece with angle seat location matches, locating piece is with centre bore, angle seat to be pressed on locating piece and centre bore is alignd, bolt is through centre bore fastening, symmetrical installation suspension ring on another two side window frames of shutter frame.Owing to adopting shutter absolute construction, assembling and disassembling is keeped in repair more convenient, workable, save time cost, significantly reduced labour intensity, improve production efficiency, this scheme also has modular functionality, and the diesel locomotive of other model also can use.
Description
Technical field
The utility model relates to a kind of ventilation shutter, particularly relates to a kind of detachable resistive braking ventilation shutter device, belongs to railway locomotive technical field.
Background technology
Diesel locomotive can be generated electricity the right kinetic energy of wheel when resistive braking by traction electric machine, electricity produces heat energy by resistance and dissipates, the blower fan that resistive braking carries this part hot blast by air channel to blowing up, fallen apart by the shutter on locomotive header extraneous to locomotive.Existing ventilation shutter and locomotive header are an entirety together with assembly welding, and shutter, for a long time by the high-temperature gas of a few Baidu, is added the frequent switch of shutter and is very easy to damage.The ventilation shutter that maintenance damages, all can only disassemble whole locomotive header, this will on locomotive header with below operate, but also locomotive header and resistive braking air outlet duct to be reinstalled.If blade of louver window damages in use procedure, change when blade of louver window is installed and will dismantle welded nut, bearing pin and bolt shaft, space is little, operating difficulties, installing/dismounting maintenance is all inconvenient, and replacing blade of louver window complex steps needs multi agent cooperation just can complete, and wastes time and energy, cost is also high, and the utilization having delayed locomotive too increases the labour intensity of workman.
Utility model content
The purpose of this utility model is the deficiency overcoming prior art, provides one to be easy to operation, installing/dismounting maintenance detachable resistive braking ventilation shutter device all easily.
The purpose of this utility model is achieved through the following technical solutions, a kind of detachable resistive braking ventilation shutter device, be placed on the corresponding mouth of locomotive header covering, bottom communicates with resistive braking air outlet duct, comprise shutter frame and blade of louver window assembling, bearing pin is passed through in blade of louver window assembling, welded nut and bolt shaft are arranged on the relative window frame of on shutter frame two, four angles of shutter frame are fixed with the angle seat of band centre bore, locomotive header covering is provided with the locating piece with angle seat location matches, locating piece is with centre bore, angle seat to be pressed on locating piece and centre bore is alignd, bolt is through centre bore fastening, symmetrical installation suspension ring on another two side window frames of shutter frame.
In order to realize the purpose of this utility model better, described suspension ring are two groups four, are relatively welded on the two sides window frame of shutter frame.
The beneficial effects of the utility model are, detachable resistive braking ventilation shutter device makes installation, dismounting, maintenance very convenient as an absolute construction, have more operability, save time cost, significantly reduce the labour intensity of workman, improve production efficiency and customer repair efficiency, this scheme also has modular functionality, and the diesel locomotive of other model also can adopt this scheme.
Accompanying drawing explanation
Fig. 1 is the utility model detachable resistive braking ventilation shutter apparatus structure schematic diagram;
Fig. 2 is the schematic diagram of the utility model detachable resistive braking ventilation shutter device practical application.
In figure: 1-suspension ring, 2-bolt, 3-locating piece, 4-roof skin, 5-air channel, 6-shutter frame, the assembling of 7-louver, 8-bearing pin, 9-welded nut, 10-bolt shaft, 11-angle seat.
Detailed description of the invention
For making goal of the invention of the present utility model, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, carry out knowing to the technical solution of the utility model and intactly describe, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
See accompanying drawing, the utility model detachable resistive braking ventilation shutter device is that whole shutter is separated from locomotive header structure, become absolute construction, be placed on the corresponding mouth of locomotive header covering 4, bottom communicates with resistive braking air outlet duct 5, blade of louver window assembling 7 is by bearing pin 8, welded nut 9 and bolt shaft 10 are arranged on the relative window frame of on shutter frame 6 two, four angles of shutter frame 6 are fixed with the angle seat 11 of band centre bore, locomotive header covering 4 is provided with the locating piece 3 with angle seat location matches, locating piece 3 is with centre bore, angle seat 11 to be pressed on locating piece 3 and centre bore is alignd, bolt 2 is fastening through centre bore, every while be symmetrically welded with two suspension ring 1 on another two side window frames of shutter frame 6, lifting in ease of assembly or unloading process, it also avoid the difficult trouble with needing to dismantle whole top cover of operation during the assembling of maintenance shutter.
During the assembling of this shutter, first blade of louver window assembling 7 is installed on shutter frame 6, and by welded nut 9 bolt shaft 10 tight, bearing pin 8 is also provided with on shutter frame 6 and blade of louver window, four angles of shutter frame 6 are welded with the angle seat 11 of band centre bore, the shutter assembled is lifted by suspension ring 1, allows angle seat 11 aim at the locating piece 3 on locomotive header covering 4, and with bolt 2 tight.Flat position and maximum opening angle when the utility model detachable resistive braking ventilation shutter blade limits its free state by bearing pin 6.
During this shutter assembly and disassembly, as long as unclamp bolt 2, lifted by suspension ring 1, change the blade of louver window of damage on the ground, this is safer, convenient than original dismounting top cover, but also need not reinstall resistive braking air outlet duct 5.After the assembling of this shutter becomes an absolute construction, there is modularization feature, the diesel locomotive of other model also can use.
