Description
Technical field
The invention belongs to the motor device in electric locomotive, more particularly to a kind of electric motor fan protective cover.
Background technology
In electric locomotive, to ensure the security of motor operation, generally it is required for setting protective cover at electric motor fan,
To prevent fan blade from getting.Mounting plate type is prevented after existing common protection is covered with full network type protective roof structure, casting shell-type protective cover
The structure of protecting wire net.Above-mentioned common protective cover needs further to be improved in terms of the convenience of simplification and the installation of structure.
The content of the invention
The present invention for solve known technology present in technical problem provide one kind it is simple in construction, easy for installation, prevent
Fan blade is got and the electric motor fan protective cover with preferable ventilation effect.
The present invention is adopted the technical scheme that to solve technical problem present in known technology：
A kind of electric motor fan protective cover, it is characterised in that：Including the first guard shield plate and the second guard shield plate, two guard shield plates are encircled
In the position for corresponding to fan outside motor casing；Two guard shield plates connect at one end through hinge, are set in the other end of two guard shield plates
There is the connection component being engaged；The connection component includes the first connecting seat and the second connecting seat, and the first connecting seat and second connect
The one end of joint chair difference riveting away from hinge connection in the first guard shield plate and the one end connected in the second guard shield plate away from hinge,
It is hinged on the first connecting seat and is connected to connecting pole, locating dowel is arranged with connecting pole, is formed with and connects on the second connecting seat
The connecting hole that post coordinates, connecting pole pass through hanging hole, are sequentially installed with pressing plate and locking nut in the outer end of connecting pole, make two shields
The other end of plate forms connection；It is formed with the first guard shield plate and in the second guard shield plate and is cracked by what spacing was evenly arranged, shape
Into air vent.
Further：Air vent in first guard shield plate is opened in close to one end of the first connecting seat of installation, the second shield
Air vent on plate is opened in close to one end of hinge connection.
Further：In the first guard shield plate and the second guard shield plate on correspond to often place disposed at air vent be formed with it is compressing
Arc exterior protrusion.
The present invention has the advantages and positive effects of：
This electric motor fan protective cover is connected by two guard shield plates at one end through hinge, is connected in two one end by connection component
Composition is connect, it directly encircles the position be fixed on motor housing and correspond to fan.This electric motor fan protective roof structure is simple, peace
Dress is convenient, and two guard shield plates are effectively prevented fan blade and got, and multiple air vents are provided with two guard shield plates, from
And preferable ventilation effect is also reached.

Embodiment
In order to further understand the content, features and effects of the present invention, hereby enumerating following examples, and coordinate accompanying drawing
Describe in detail as follows：
Fig. 1-5, a kind of electric motor fan protective cover are referred to, its innovative point is：Including the first guard shield plate 1 and the second shield
Plate 2, two guard shield plates are encircled in outside motor casing.Two guard shield plates are connected at one end through hinge 3, and the other end of two guard shield plates is provided with
The connection component being engaged.The connection component includes the first connecting seat 4 and the second connecting seat 5, and the first connecting seat and second connect
The one end of joint chair difference riveting away from hinge connection in the first guard shield plate and the one end connected in the second guard shield plate away from hinge.
It is hinged on the first connecting seat and is connected to connecting pole 6, one end that connecting pole is connected with the first connecting seat can uses ball head structure, bulb
Part is formed by the connecting seat of bearing pin 7 and first and connected, and locating dowel 8 is arranged with connecting pole, is formed with the second connecting seat
The connecting hole 5-1 coordinated with connecting pole, the second connecting seat can use and the steel plate knot of vertical bending set at middle part shown in accompanying drawing
Structure, connecting hole are arranged in the vertical bending in middle part.Connecting pole passes through hanging hole, and the He of pressing plate 9 is sequentially installed with the outer end of connecting pole
Locking nut 10, the other end of two guard shield plates is set to form connection.Be formed with the first guard shield plate and in the second guard shield plate by
Cracked away from what is be evenly arranged, form air vent.
In above-mentioned electric motor fan protective roof structure, the air vent in the first guard shield plate is further preferably opened in close to installation
One end of first connecting seat, the air vent in the second guard shield plate are further preferably opened in close to one end of hinge connection.So,
Can two relative on whole protective cover position form ventilation, so as to can reach good ventilation effect.
In above-mentioned electric motor fan protective roof structure, correspond in the first guard shield plate and in the second guard shield plate and often locate air vent
Compressing arc exterior protrusion 11 is further formed with 11-1, i.e. air vent is arranged on compressing arc outer lug
Close to the position of a side portion in portion.
The foregoing is only the present invention preferably applies example, is not used for limiting the practical range of the present invention.That is Fan Yibenfa
The equivalent changes and modifications that the content of bright claim is done, each fall within the technical scope of the present invention.
