Abstract
The utility model relates to an observation hole die for a ballastless rail plate, which is provided with a bottom die, a cone die arranged on the bottom die and a positioning rod for fixing the cone die on the bottom die. The bottom die is provided with a through hole. The middle part of the cone die is provided with a cone die through hole. The section of the positioning rod is of a T-shape. The upper part of the positioning rod is a circular limit part in fit with the upper end of the cone die. The middle part of the positioning rod is a rod body. The lower part of the positioning rod is a screw thread part. The rod body of the positioning rod is arranged in the cone die through hole of the cone die. The lower part of the positioning rod is arranged on the lower end face of the bottom die after passing through the through hole of the bottom die and is screwed down and fixed by a nut. The observation hole die for the ballastless rail plate connects and fixes the cone die on the bottom die by the positioning rod and is convenient and rapid to install. The upper end face of the cone die is provided with a counter bore. The shape of the limit part of the positioning rod is matched with that of the counter bore. In the process of screwing the nut, the phenomenon that the positioning rod rotates cannot be generated. The observation hole die for the ballastless rail plate has high practicality.
Description
Technical field
The utility model relates to a kind of fragment-free track slab processing unit (plant), particularly a kind of fragment-free track slab peep hole mould.
Background technology
In field of track traffic, the meaning of " tiny fragments of stone, coal, etc. " is the stone of fritter.The track of conventional track traffic all on the basis of fritter stone, re-lays sleeper, and then on sleeper steel rail laying, run at high speed but this track is unsuitable for train.The development of world's high-speed railway confirms that if the high-speed railway foundation engineering is used conventional rail system, the railway ballast efflorescence is serious, and line maintenance is frequent, and security, comfortableness, economy are all relatively poor relatively.Therefore, in current high speed railway construction, slab track is widely used, comparing with the conventional rails traffic, no longer is stone upper berth sleeper, the sleeper rail of putting on the shelf, do not have coccolith, a sleeper under this track, but just spread by concrete cast prefabricated track plate and 500 meters gapless rail links, this track applies to high-speed railway, can make train very smooth-going when running at high speed, nothing is jolted, and low noise can also reduce dust, beautify the environment, reduce maintenance.
Because the non-fragment orbit plate bulk is bigger, need to offer 3 peep holes on the heart line therein, be convenient to contraposition and install, also can under the irregular situation of region, come casting cement simultaneously, when processing track plate, need in mould, add relevant guidance tape peep hole mould as plug hole.
The utility model content
The purpose of this utility model is to provide a kind of easy for installation, demoulding fragment-free track slab peep hole mould smoothly.
The technical scheme that realizes the utility model purpose is: a kind of fragment-free track slab peep hole mould, have bed die and be arranged on the circular cone mould on the bed die and be used for the circular cone mould is fixed on backstay on the bed die, bed die is provided with through hole, circular cone mould middle part is provided with the prod cast through hole, the backstay cross sectional shape is "T"-shaped, its top is the circular limiting section that matches with circular cone mould upper surface, the middle part is the body of rod, the bottom is the threaded portion, the body of rod of backstay is arranged in the prod cast through hole of circular cone mould, the through hole that bed die is passed in the bottom is arranged on the bed die lower surface, and is tightened by nut.
The circular cone mould upper surface of above-mentioned fragment-free track slab peep hole mould has counterbore, and the limiting section of described backstay and above-mentioned counterbore match and be arranged in the counterbore.
The counterbore of the circular cone mould upper surface of above-mentioned fragment-free track slab peep hole mould is the polygon counterbore, and the limiting section shape and the counterbore shape of described backstay match.
The counterbore of the circular cone mould upper surface of above-mentioned fragment-free track slab peep hole mould is the hexagon counterbore.
The utlity model has following characteristics: (1) the utility model is fastened on the circular cone mould on the bed die by backstay, and is quick and easy for installation; (2) circular cone mould of the present utility model upper surface has counterbore, and the limiting section and the counterbore shape of backstay match, and the backstay transfer phenomenon can not take place in the process that nut is rotated with, the practicality height.
