Abstract
The utility model provides a high-abrasion resistance point rail which has high strength, long service life and low cost. The high-abrasion resistance point rail comprises a point rail body and a connection plate, wherein the contact position of the point rail body and train wheels is coated with a strengthening layer and an abrasion resistant layer positioned on the strengthening layer; the thickness of the strengthening layer is 2-4 mm, and the thickness of the abrasion resistant layer is 1-2 mm. The point rail is greatly enhanced in abrasion resistant property and strength and prolonged in service life because the strengthening layer and the abrasion resistant layer are additionally arranged on the contact position of the point rail body and the train wheels, thereby increasing the driving safety and saving the steels, the fund and the labor power.
Description
Technical field
The utility model relates to a kind of rail assembly, especially a kind of high-wearing feature tongue.
Background technology
Existing tongue all is to process with common rail, directly is assembled into bifilar parallel straight line or the mobile track switch of curve.Because the condition of work of tongue is very abominable with environment, so tongue tread side is easy to wearing and tearing, and the tongue rail head is easy to piece, fracture etc., influence traffic safety, and often a large amount of steel, fund and manpower are wasted in replacing, also influence the normal operation of train.
The utility model content
The utility model provides the tongue of a kind of intensity height, long service life.
Realize the high-wearing feature tongue of the utility model purpose; Comprise tongue body and junction plate; The contact site of said tongue body and train wheel is covered with one deck strengthening layer and the wearing layer that is positioned at said strengthening layer top; The thickness of said strengthening layer is 2～4mm, and the thickness of said wearing layer is 1～2mm.
The beneficial effect of the high-wearing feature tongue of the utility model is following:
The high-wearing feature tongue of the utility model; Owing to increasing strengthening layer and wearing layer with the train wheel contact site, therefore improving the anti-wear performance and the intensity of tongue greatly, the application life of having improved tongue; Improve formation safety, saved steel, fund and manpower.
Description of drawings
Fig. 1 is the structural representation of the high-wearing feature tongue of the utility model.
The specific embodiment
As shown in Figure 1; The high-wearing feature tongue of the utility model; Comprise tongue body 1 and junction plate 2; Said tongue body 1 is covered with one deck strengthening layer 3 and the wearing layer 4 that is positioned at said strengthening layer 3 tops with the contact site of train wheel, and the thickness of said strengthening layer 3 is 2～4mm, and the thickness of said wearing layer 4 is 1～2mm.
The advantage of the high-wearing feature tongue of the utility model is following:
The high-wearing feature tongue of the utility model; Owing to increasing strengthening layer 3 and wearing layer 4 with the train wheel contact site, therefore improving the anti-wear performance and the intensity of tongue greatly, the application life of having improved tongue; Improve formation safety, saved steel, fund and manpower.
Embodiment recited above describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Design under the spiritual prerequisite not breaking away from the utility model; Various distortion and improvement that the common engineers and technicians in this area make the utility model technical scheme are in the protection domain that claims of the people's the utility model that all should fall are confirmed.
Claims (1)
1. high-wearing feature tongue; It is characterized in that: comprise tongue body and junction plate; The contact site of said tongue body and train wheel is covered with one deck strengthening layer and the wearing layer that is positioned at said strengthening layer top, and the thickness of said strengthening layer is 2～4mm, and the thickness of said wearing layer is 1～2mm.
