Abstract
The utility model relates to a track convenient to assemble. The track comprises steel rails and a connecting piece, and is characterized in that the connecting piece consists of a male dovetail and a female dovetail, the male dovetail is integrally connected with front end portions of the pair of I-shaped steel rails, and the female dovetail is integrally connected with rear end portions of the pair of I-shaped steel rails. The upper sides of the front end portions of the pair of I-shaped steel rails connected with the male dovetail are respectively provided with an over-joint assist external angle, and the upper sides of the front end portions of the pair of I-shaped steel rails connected with the female dovetail are respectively provided with an over-joint assist internal angle that is matched with the over-joint assist external angle. The track of the utility model can be combined into an integral body and is convenient to mount and replace, and the steel rails can be effectively prevented from being bent or deformed due to expansion caused by heat and contraction caused by cold, so as not to affect the train speed.
Description
Technical field
The utility model relates to a kind of track, exactly is a kind of track of being convenient to assemble.
Technical background
Train is the vehicles of people's long-distance travel; The track of train is to adopt adding the method for a power-assisted plate bolt on two sections involutory backs of rail to be formed by connecting at present; For solving expanding with heat and contract with cold of rail, to the fashionable counterpart seam that leaves, therefore; Track can't guarantee that not only two sections rail influence the speed of a motor vehicle because of the flexural deformation of expanding with heat and contract with cold, and can't be in aggregates.
The utility model content
The utility model purpose is to existing problem, provides a kind of to people and can not only make the track after involutory in aggregates, can prevent effectively rail because of the flexural deformation of expanding with heat and contract with cold, influence the speed of a motor vehicle, and install, the track assembled is convenient in replacing easily.
The utility model comprises rail and connector, it is characterized in that: connector is made up of dovetail public affairs and dovetail mother, and dovetail is public to link into an integrated entity with a pair of worker's shaped steel rail leading section, and dovetail mother and a pair of worker's shaped steel rail rearward end link into an integrated entity.
Be connected with the public a pair of worker's shaped steel rail front end upside of dovetail and respectively be provided with one and cross seam power-assisted exterior angle, be connected with the female a pair of worker's shaped steel rail front end upside of dovetail respectively be provided with one with cross stitch that the power-assisted exterior angle is complementary cross seam power-assisted interior angle.
During use, as long as public promptly the completion with the dovetail mother who inserts another section rail of one section rail dovetail docked, thus the assembling of completion track.
The effect of the utility model
The utility model is because rail is to be accomplished by the grafting that dovetail is public and dovetail is female, therefore can not only make the track after involutory in aggregates, can prevent effectively rail because of the flexural deformation of expanding with heat and contract with cold, influence the speed of a motor vehicle, and install, change conveniently.
