Abstract
The utility model belongs to the technical field of detection, and provides a central distance detection gauge for an embedded casing of a ballastless track slab. The central distance detection gauge consists of a transverse beam (1) and two cylindrical pins (2), wherein the two cylindrical pins (2) are fixed on the transverse beam (1). By adopting the central distance detection gauge, the prefabrication quality and the inspection working efficiency of the track slab are improved; and the central distance detection gauge has the characteristics of simple structure and convenience of operation.
Description
Technical field
The utility model belongs to the detection technique field, relates generally to a kind of fragment-free track slab and detects gauge with service sleeve centre distance.
Technical background
Plate-type ballastless track technology applying more and more widely on world's high speed railway track, Lines for Passenger Transportation such as the Beijing-Tianjin that China has been open to the traffic, military wide and Beijing-Shanghai, the Shi Wu that building, Harbin-to-Dalian all are to adopt the non-fragment orbit technology.
China on the basis of organizing relevant unit absorbing advanced foreign technology in 2004 by the Ministry of Railways, independent research CRTS I type and CRTS II type and CRTS III track plate, realized the production domesticization of fragment-free track slab and mould thereof.
Each CRTS I type track plate factory production task is very heavy, to produce 20,000 in the duration about a year and a half surplus block track plate, all to check its each size then one by one.Every block of track plate has 24 or 32 service sleeves, all will measure its relative positional accuracy one by one by the template drawing, need measure 30 to 40 sizes approximately.If measurers such as employing vernier caliper are measured one by one, size can not directly be measured, and needs to convert, so size is inaccurate and efficient is too low.
Summary of the invention
The purpose of this utility model provides a kind of fragment-free track slab and detects gauge with service sleeve centre distance, the size and the relative positional accuracy that are used for fast detecting service sleeve centre distance, make it can improve track plate prefabrication quality and work for inspection efficient, and have simple in structure, convenience operation.
The technical scheme that its invention task of finishing the utility model is adopted is: a kind of fragment-free track slab detects gauge with service sleeve centre distance, and described centre distance purchase inspection gauge is made of crossbeam and two straight pins; Described two straight pins are fixed on the crossbeam.
Two straight pin centre distance of described centre distance purchase inspection gauge are 382 ± 0.1mm, in order to detect the centre distance of single cushion cap two service sleeves of track plate.
Two straight pin centre distance of described centre distance purchase inspection gauge are 629 ± 0.1mm or 617 ± 0.1mm, in order to detect the vertically centre distance of adjacent two cushion cap service sleeves of track plate.
Two straight pin centre distance of described centre distance purchase inspection gauge are 1514 ± 0.1mm, in order to detect the centre distance of the horizontal service sleeve of track plate.
A kind of fragment-free track slab that the utility model proposes detects gauge with service sleeve centre distance, the size and the relative positional accuracy that are used for fast detecting service sleeve centre distance, improve track plate prefabrication quality and work for inspection efficient, and had simple in structure, convenience operation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, crossbeam, 2, straight pin.
Embodiment
With specific embodiment the utility model is illustrated in conjunction with the accompanying drawings:
As shown in Figure 1, a kind of fragment-free track slab detects gauge with service sleeve centre distance, and described centre distance purchase inspection gauge is made of crossbeam 1 and two straight pins 2; Described two straight pins 2 are fixed on the crossbeam 1 that square steel tube makes.Two straight pin centre distance of described centre distance purchase inspection gauge can be 382 ± 0.1mm, in order to detect the centre distance of single cushion cap two service sleeves of track plate.Two straight pin centre distance of described centre distance purchase inspection gauge can be 629 ± 0.1mm or 617 ± 0.1mm, in order to detect the vertically centre distance of adjacent two cushion cap service sleeves of track plate.Two straight pin centre distance of described centre distance purchase inspection gauge can be 1514 ± 0.1mm, in order to detect the centre distance of the horizontal service sleeve of track plate.
When track plate service sleeve centre distance detects the gauge use crossbeam 1 is held level with both hands, it is qualified making two straight pins can insert the service sleeve hole smoothly.
