Description
Technical field
The utility model relates to track switch tie accessory, especially refers to a kind of concrete switch sleeper service sleeve.
Background technology
Available coagulation soil switch tie generally adopts plastic bushing with service sleeve, by plastic bushing is embedded in the concrete switch sleeper in advance, changes the connected mode of railway spike and concrete switch sleeper, and making it easy to construct to prolong the application life of switch tie.
But owing to plastic bushing directly is cast in the concrete switch sleeper, owing to concern the application life of plastic sheath itself, after plastic sheath lost efficacy, its replacing and maintenance all very bothered inconvenience.
The utility model content
The purpose of this utility model is to provide a kind of concrete switch sleeper service sleeve easily that keeps in repair and change.
A kind of concrete switch sleeper service sleeve provided by the utility model comprises plastic bushing, it is characterized in that: it also comprise one with described plastic bushing carry out sheathed shell body.
With in the service sleeve, shell body is the shaped spiral housing with internal and external screw thread at above-mentioned concrete switch sleeper.
With in the service sleeve, plastic bushing is provided with external screw thread at above-mentioned concrete switch sleeper, and the internal thread of the external screw thread of this plastic bushing and described shell body carries out screw thread and spins.
With in the service sleeve, shell body is a stainless steel tube at above-mentioned concrete switch sleeper.
With in the service sleeve, the external screw thread of shell body adopts the form of full thread or half-thread at above-mentioned concrete switch sleeper.
Since adopted above-mentioned technical solution, after plastic bushing lost efficacy,, very convenient as long as change one again after screwing out plastic bushing.The utility model is used for the railway speed increase engineering, the time during scooter 200～300KM/, effect is remarkable.
Description of drawings
Fig. 1 is the structural representation of the utility model concrete switch sleeper with service sleeve.
The specific embodiment
As shown in Figure 1, the utility model concrete switch sleeper comprises a plastic bushing 1 and a shell body 2 with service sleeve.Plastic bushing 1 is provided with external screw thread, and shell body 2 is the shaped spiral housings with internal and external screw thread, and the internal thread of the external screw thread of this plastic bushing 1 and described shell body 2 carries out screw thread and spins.
Operating principle of the present utility model: the utility model sleeve pipe is embedded in advance in the fixing hole 3 of concrete switch sleeper,, track 5 is fixed by the pressing plate 6 that is connected with railway spike 4.
Therefore, after plastic bushing lost efficacy,, just very convenient as long as change one again after screwing out plastic bushing.The utility model is used for the railway speed increase engineering, the time during scooter 200～300KM/.
Above embodiment is only for the usefulness that the utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong within the category of the present utility model, should be limited by each claim.And include within the scope of claim.
