Abstract
The utility model discloses a novel point rail structure which comprises a point rail body. A panel is arranged on a working face of the point rail body. The panel and the point rail body are connected through a detachable structure. The high-strength abrasion-resistant panel is added on the point rail, abrasion-resistant processing is carried out on an easily-abraded portion, abrasion loss is lowered, the service life of the point rail is prolonged, and line operation cost is lowered. The panel and the point rail can be disassembled and assembled conveniently, point rail maintaining difficulty and workload are lowered, and maintaining working efficiency is improved.
Description
Technical field
The utility model relates to track technical field, especially relates to a kind of novel tongue structure.
Background technology
Train turns on another group track from one group of track by the tongue of track switch; Therefore, this place of tongue is easy to wear.
Current tongue structure is an overall structure, and and circuit rail be same material, wear and tear more serious, the wearing and tearing of bent tongue are particularly outstanding, wear away needs replacing in serious month once, increased the operation cost of circuit; And tongue is overall structure, integral replacing, complicated operation, railway worker safeguards that labour intensity is large, inefficiency, holding time is long, affects the train passage time.
Utility model content
Not enough for prior art, technical problem to be solved in the utility model is to provide a kind of novel tongue structure easy to maintenance.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of novel tongue structure, comprise tongue body, and the work plane of described tongue body is provided with panelling, between described panelling and tongue body, by demountable structure, is connected.
Further, described detaching structure comprises set bolt and hold-down nut, on described tongue body and panelling, is equipped with the connecting hole passing for set bolt.
Between described tongue body and panelling, be provided with tack coat.
Described tongue body is provided with step, and panelling is located on step, the top of the top parcel tongue of panelling.
Described hold-down nut inner side is provided with spring washer.
Described panelling is the steel plate of NM400.
The utility model compared with prior art, has the following advantages:
On tongue, set up the panelling of high-strength wearable, commute abrading section carries out Wear-resistant Treatment, reduces abrasion, extends the application life of tongue, reduces circuit running cost; Between panelling and tongue, be convenient to remove and install, reduced tongue maintenance difficulties and workload, improved the operating efficiency of safeguarding; Safeguard and only need to change panelling, without integral replacing tongue, reduced maintenance cost.
Accompanying drawing explanation
Below the expressed content of each width accompanying drawing of this manual and the mark in figure are briefly described:
Fig. 1 is the utility model tongue structural representation.
In figure: 1. panelling, 2. tongue body, 3. tack coat, 4. set bolt, 5. packing ring, 6. hold-down nut.
The specific embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1, this novel tongue structure, comprises tongue body 2, the work plane of tongue body 2 is provided with panelling 1, wherein, and the steel plate that panelling 1 is NM400, use high-strength abrasion-proof steel NM400 partly to inlay reinforcement to tongue milling, the abrasion resistance of comparing existing tongue improves 2-3 times of effect.Extend the application life of tongue, reduce circuit running cost.
Between panelling 1 and tongue body 2, by demountable structure, be connected.Reduce tongue maintenance difficulties and workload, improved the operating efficiency of safeguarding.
Detaching structure comprises suitable set bolt 4 and hold-down nut 6, on tongue body 2 and panelling 1, is equipped with the connecting hole passing for set bolt, and set bolt 4 is through connecting hole, and the nut 6 that is tightened is fixed together tongue body 2 and panelling 1.Detaching structure can also be selected other easy-to-dismount locking mechanism.
In hold-down nut 6 inner sides, be provided with packing ring 5, wherein, the preferred spring washer of packing ring 5, improves fixing reliability between tongue body 2 and panelling 1.Or use two hold-down nuts to be tightened side by side.
Between tongue body 2 and panelling 1, be provided with tack coat 3.Tack coat is comprised of modification acrylate and glass fabric, tongue body and panelling is bonded together, to reduce rigidity friction between the two and to play certain cushioning effect.
Tongue body 2 is provided with step, and panelling 1 is located on step, the top of the top parcel tongue of panelling.This fit structure makes between tongue body and panelling fixing reliable.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that design of the present utility model and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
