Abstract
The utility model discloses a kind of subway the 3rd rail insulation column body, it comprises one and is positioned at the pedestal of bottom and is positioned at the connecting portion of upper end, is provided with a supporter between described pedestal and connecting portion; This subway the 3rd rail insulation column body adopts glass-reinforced plastic material to make.Described supporter is cone, is arranged on pedestal, and the diameter of the upper surface of supporter is less than the diameter of bottom face.Described connecting portion is a disc structure, is provided with an on-slip guide groove in described connecting portion.The utility model adopts glass-reinforced plastic material to make, sturdy and durable, corrosion-resistant, and evenly, radiation is little in heat radiation, can reduce magnet interference, improve shock resistance, environmental protection; Intercept electricity, good insulation preformance simultaneously, can effectively stop electricity damage time electricity directly import the earth, supporter adopt cone, therefore stability and firm performance good, use more safe and reliable.
Description
Technical field
The utility model relates to a kind of insulation column body, particularly relates to a kind of subway the 3rd rail glass fibre reinforced plastic insulating Body of pillar, belongs to field of urban traffic.
Background technology
At present, city underground many employings third-rail current collection mode, namely at the outer parallel laid one article of I-steel of two rails as the 3rd rail (conductor rail), subway electric car by current-collecting device from third-rail current collection.The unsettled setting of 3rd rail, insulation column body refers to the insulation column body for supporting the 3rd rail installed on subway the 3rd rail is along the line, and the 3rd rail needs several support to provide support along the line.
The Main Function of the 3rd rail is that high voltage source is transported in the driving machine of subway electric locomotive by pantograph, 3rd rail is fixed on roadbed by support, due to the 3rd rail being connected with high voltage source, need to arrange an insulation column body between support and the 3rd rail, prevent the high voltage source on the 3rd rail to be delivered on roadbed.
But existing insulation column body is mostly adopt same with thermosetting compound material by die cast, and it tolerates poor performance, and useful life is short, dispels the heat uneven, poor electric conductivity, and stability and firm poor-performing, there is potential safety hazard.
Utility model content
In view of the defect existed in above-mentioned prior art, the purpose of this utility model is to provide a kind of heat radiation evenly, and radiation is little, reduces magnet interference, intercepts electricity, good insulation preformance, while stability and good subway the 3rd rail insulation column body of firm performance.
In order to achieve the above object, the technical scheme that the utility model is taked is:
A kind of subway the 3rd rail insulation column body, it comprises one and is positioned at the pedestal of bottom and is positioned at the connecting portion of upper end, is provided with a supporter between described pedestal and connecting portion;
This subway the 3rd rail insulation column body adopts glass-reinforced plastic material to make.
As one of preferred version of the present utility model, described supporter is cone, is arranged on pedestal, and the diameter of the upper surface of supporter is less than the diameter of bottom face, adds stability and fastness, uses more safe and reliable.
As one of preferred version of the present utility model, described connecting portion is a disc structure, is provided with an on-slip guide groove in described connecting portion, more firmly, and shock resistance is improved.
Compared with prior art, the beneficial effects of the utility model are:
The utility model adopts glass-reinforced plastic material to make, sturdy and durable, corrosion-resistant, and evenly, radiation is little in heat radiation, can reduce magnet interference, improve shock resistance, environmental protection; Intercept electricity, good insulation preformance simultaneously, can effectively stop electricity damage time electricity directly import the earth, supporter adopt cone, therefore stability and firm performance good, use more safe and reliable.
Accompanying drawing explanation
In order to be illustrated more clearly in architectural feature of the present utility model and technical essential, below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Fig. 1 is the structural representation of a kind of subway the 3rd rail insulation column body disclosed in the utility model embodiment;
Fig. 2 is the cutaway view of a kind of subway the 3rd rail insulation column body disclosed in the utility model embodiment.
Description of reference numerals: 1-pedestal, 2-connecting portion, 3-supporter, 20-on-slip guide groove.
Embodiment
Below in conjunction with the accompanying drawing in the present embodiment, carry out specifically, clearly and completely describing to the technical scheme in embodiment.
Shown in Fig. 1 and Fig. 2, for a kind of subway the 3rd rail insulation column body of the present embodiment, it adopts glass-reinforced plastic material to make, sturdy and durable, corrosion-resistant, evenly, radiation is little in heat radiation, can reduce magnet interference, improve shock resistance, environmental protection, intercepts electricity, good insulation preformance simultaneously, and when can effectively stop electricity to damage, electricity directly imports the earth.
This subway the 3rd rail insulation column body comprises one and is positioned at the pedestal 1 of bottom and is positioned at the connecting portion 2 of upper end, is provided with a supporter 3 between described pedestal 1 and connecting portion 2; Described supporter 3 is cone, is arranged on pedestal, and the diameter of the upper surface of supporter is less than the diameter of bottom face, adds stability and fastness, uses more safe and reliable.
As one of the preferred version of the present embodiment, described connecting portion is a disc structure, is provided with an on-slip guide groove in described connecting portion, more firmly, and shock resistance is improved.
In sum, the present embodiment adopts glass-reinforced plastic material to make, sturdy and durable, corrosion-resistant, and evenly, radiation is little in heat radiation, can reduce magnet interference, improve shock resistance, environmental protection; Intercept electricity, good insulation preformance simultaneously, can effectively stop electricity damage time electricity directly import the earth, supporter adopt cone, therefore stability and firm performance good, use more safe and reliable.
Above-mentioned embodiment; be only and technical conceive of the present utility model and architectural feature are described; object is stakeholder can be implemented according to this; but above said content does not limit protection range of the present utility model; every any equivalence done according to Spirit Essence of the present utility model changes or modifies, and all should fall within protection range of the present utility model.
