Abstract
The invention relates to an insulation foundation bolt for a low-voltage rail. The insulation foundation bolt comprises a steel screw rod and an L-shaped embedded rod, wherein the screw rod and the embedded rod are produced through integral moulding, and the diameter of the screw rod is less than the diameter of the embedded rod; an external thread is arranged on the screw rod; a nut, an elastic insulation gasket and a steel gasket are sequentially connected to the screw rod in a sleeving manner from the outside to inside towards the direction of the embedded rod; and an aluminium oxide ceramic insulation layer is moulded on the outer surface of the embedded rod through hot pressing. The whole technical scheme is ingenious and practical in design; the insulativity of the foundation bolt is improved; and meanwhile, the construction process of the low-voltage rail of an electric flat carriage is greatly simplified, and the construction cost is reduced.
Description
Technical field
The present invention relates to the basic fittings of low voltage electric flat carriage low voltage rail, specifically a kind of insulation lower margin spiral shell
Bolt.
Background technology
Electric flat carriage is widely used in the large enterprises such as industrial and mineral, metallurgy and cast steel, and the voltage that low voltage electric flat carriage uses is
The safe voltage of 36v.Low voltage electric flat carriage often in the state of movement, so generally not by the way of cable power supply, and
Be by low voltage rail transmit electric energy while conveying articles.The low voltage rail of low voltage electric flat carriage typically passes through foundation bolt
Install on the ground, now bolt is equivalent to the earthing pole of electric flat carriage it is therefore necessary to carry out insulation processing to foundation bolt, with
Separate the electrical connection of itself and the earth.
At present, foundation bolt is poured in basic preformed hole using sulphur-bonded mortar, for ensureing every foundation bolt over the ground
Insulation.But the preparation of sulphur-bonded mortar and perfusion must be in high temperature（110 DEG C～180 DEG C）Under carry out, complex process；And applying
Work on-the-spot meeting produces the toxic and harmfuls such as a large amount of sulfur dioxide, carbon dioxide, has a strong impact on the healthy of workmen, with
When also pollute environment, used in the preparation process of sulphur-bonded mortar open flame source also increase scene danger.
Content of the invention
The present invention is exactly directed to technical problem present in prior art, provide a kind of structure simple and low cost low pressure
Track insulation foundation bolt, meets design requirement using the insulation resistance value that this bolt can not only ensure low voltage rail, simultaneously
Also omit the operation irrigating sulphur-bonded mortar in original track construction technology, greatly reduce difficulty of construction, improve efficiency of construction.
To achieve these goals, the technical solution used in the present invention is, a kind of low voltage rail insulation foundation bolt, bag
Include steel screw rod and pre-buried bar, described screw rod is integrally formed with pre-buried bar and makes, and the diameter of screw rod be less than the diameter of pre-buried bar,
Described screw rod is provided with external screw thread, on described screw rod towards pre-buried bar direction be socketed with successively from outside to inside nut,
Resilient grommet and steel washer, have alumina ceramic insulating layer in the outer surface of described pre-buried bar through hot-forming.
As a modification of the present invention, described pre-buried bar be shaped as " L " shape, its kink is set to arc.
As a modification of the present invention, the thickness of described alumina ceramic insulating layer is 2～5 millimeters, due to aluminium oxide
The effect of ceramic insulating layer makes foundation bolt be not turned on the earth isolation, the rubber insulation using compared to tradition, oxidation
The insulation effect of aluminum ceramic insulating layer is more significantly, and has good mechanical performance and high temperature resistant and acid-alkali-corrosive-resisting, makes
Use life-span length.
As a modification of the present invention, described resilient grommet is made using phenolic resin cotton cloth plate, and its thickness is
5-10 millimeter, can effectively guarantee the insulating properties between screw rod and pre-buried bar.
As a modification of the present invention, described nut be hex nut, the both ends of nut be provided with 1*45 ° outer fall
Angle.
As a modification of the present invention, described steel washer is the flat shim made using stainless steel material, its external diameter ratio
The diameter of described pre-buried bar is big.
With respect to prior art, the present invention's is simple and reliable for structure, and intensity is high, low cost of manufacture, long service life；To this
Insulation foundation bolt is used in direct for bolt Transducers Embedded in Concrete during low voltage rail, so regardless of the whether insulation against ground of every bolt
No longer affect low voltage rail insulation over the ground, do not needing to irrigate the operation of sulphur-bonded mortar therefore in work progress, both sides
Construction, accelerate progress it is ensured that quality, also reduce construction cost simultaneously, decrease the discharge of toxic and harmful.
Brief description
Fig. 1 is the structural representation of the present invention.
In figure：1- screw rod, the pre-buried bar of 2-, 3- hex nut, 4- resilient grommet, 5- steel washer, 6- aluminium oxide ceramics
Insulating barrier.
Specific embodiment
In order to deepen the understanding of the present invention and understanding, the invention will be further described below in conjunction with the accompanying drawings and introduces.
As illustrated, a kind of low voltage rail insulation foundation bolt, including using high-carbon steel through powder metallurgical technique system
The screw rod 1 becoming and the pre-buried bar of L-type 2, described screw rod 1 is integrally formed using Q235 round steel with pre-buried bar 2 and makes, and screw rod 1 is straight
Footpath is less than the diameter of pre-buried bar 2.Described screw rod 1 is provided with full thread.Towards the direction of pre-buried bar 2 on described screw rod 1
It is socketed with hex nut 3, resilient grommet 4 and rustless steel steel washer 5 from outside to inside successively.Described steel washer 5 is using not
The flat shim that rust Steel material is made, the external diameter of steel washer 5 is bigger than the diameter of described pre-buried bar 2, is so able to ensure that steel washer 5 is right
Threaded hex nut 3 on screw rod 1 has good supporting role.Described resilient grommet 4 adopts phenolic resin cotton
Fabric swatch is made, and its thickness is 5-10 millimeter, and the diameter of resilient grommet 4 is slightly larger than the diameter of pre-buried bar 2, so be enough to
Guarantee the insulation degree between screw rod and pre-buried bar.There is one layer of 2～5 millimeters thick the outer surface heat of described pre-buried bar 2 is molded
Alumina ceramic insulating layer 6.The whole ingenious practicality of Technical Design, improves the insulating properties of foundation bolt, in low tension
Bury by this insulation foundation bolt direct-burried or with after high-strength grout in the work progress of dynamic flatcar track, cancel preparation and fill
The operation of note sulphur-bonded mortar, and the construction technology with reference to common foundation bolt, thus also greatly simplify low-pressure electric put down
The construction technology in track road, reduces construction cost.
It should be noted that above-described embodiment, not it is used for limiting protection scope of the present invention, in technique scheme
On the basis of done equivalents or substitute each fall within the scope that the claims in the present invention are protected.
