Abstract
The utility model relates to an embedded unballasted rail slab casting rail bearing casing, which comprises a rail slab bottom die. Rail bearing table stepped holes are evenly distributed on the rail slab bottom die; a rail bearing casing molded by casting number 35 cast steel is embedded into each rail bearing table stepped hole; the rail bearing casing is formed through mechanical processing; and each rail bearing casing is connected with the rail slab bottom die through a bolt. The rail bearing casing is cast and molded by adopting the number 35 cast steel and formed through the mechanical processing, thereby accuracy and rigidity of the rail bearing casing reach requirements. Besides, cast and molded rail slabs are enabled to be molded in one time, and mechanical processing for the cast and molded rail slabs through large-scale numerical control grinder is not needed, thereby the embedded unballasted rail slab casting rail bearing casing achieves short processing cycle, high accuracy, comparatively low processing cost, accurate positioning, convenient installation, reasonable design and high practicability.
Description
Technical field
The utility model relates to a kind of fragment-free track slab processing unit (plant), particularly a kind of embedded fragment-free track slab casting mold support rail shell.
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.
At present, domestic general fragment-free track slab has the branch of I type fragment-free track slab and II type fragment-free track slab, I type fragment-free track slab is provided with projection on the position of steel rail laying platform is the support rail platform, steel rail laying is on the support rail platform, it is assembled that the casting mold of this fragment-free track slab mostly uses sheet metal to connect, because simple shape, control by mould sheet metal thickness and machined precision, generally can both guarantee the product quality and the required precision of fragment-free track slab, but the support rail platform fastener for installing of this I type fragment-free track slab does not have fixture, makes the precision of steel rail laying not guarantee; Has special fixture on the support rail platform of II type fragment-free track slab, be that the support rail platform is provided with groove and projection, can carry out spacing to rail, thereby guaranteed the steel rail laying precision, but because its fixture structure is comparatively complicated, the casting mold of production unit mostly adopts the T14 stretching steel plate of 3 millimeters thickness or other similar materials to form by the mold pressing stretching at present, because the precision and the rigidity of mould can't reach requirement, therefore pour into a mould the track plate that comes out and also need to pass through secondary operations, promptly the track plate of moulding by casting is carried out machining by the large-sized numerical control grinding machine, make it reach the product size required precision, the cycle of producing the track plate like this is longer, and processing charges is high, can't satisfy the needs of present track traffic industry.
The utility model content
The purpose of this utility model is to provide a kind of process-cycle short, the fragment-free track slab casting mold support rail shell that precision height and processing charges are lower.
The technical scheme that realizes the utility model purpose is: a kind of embedded fragment-free track slab casting mold support rail shell, has track plate bed die, even distribution support rail stepladders hole on the described track plate bed die, each support rail stepladders hole is embedded to be connected to by No. 35 cast steel cast moldings and the support rail shell that forms by machine finishing, and the support rail shell is connected with track plate bed die by bolt.
Each support rail stepladders hole periphery of the track plate bed die of above-mentioned embedded fragment-free track slab casting mold support rail shell is distribution installing hole and locating hole evenly, described support rail shell edge is provided with shoulder hole that matches with track plate bed die position of mounting hole and the pin hole that matches with position of positioning hole, and pin is arranged in locating hole and the pin hole.
The end cap of the bolt of above-mentioned embedded fragment-free track slab casting mold support rail shell is the circular cupping with the shoulder hole interference fit, the end cap edge is provided with semicircle breach, the shoulder hole edge is provided with the breach that matches with semicircle breach, and alignment pin is arranged in the synthetic circular hole of semicircle breach and breach.
The utlity model has following characteristics: (1) support rail shell of the present utility model adopts No. 35 cast steel cast moldings and forms by machining, the support rail shell wall is thick to be 16 millimeters, its precision and rigidity all can reach the cast requirement, make track plate one-shot forming behind the moulding by casting, need not the track plate of moulding by casting to be carried out machining by the large-sized numerical control grinding machine, process-cycle is short, and precision height and processing charges are lower; (2) support rail shell of the present utility model is located by pin, and accurate positioning connects by bolt behind the embedding bed die, and is easy for installation; (3) consider the thickness limits of track plate bed die and support rail shell, the utility model bolt end cap is circular, with the shoulder hole interference fit, and its rotation direction is positioned by alignment pin, after connection is finished grinding process is carried out in the upper surface of bolt end cap and support rail shell, guarantee that itself and bed die end face are in same plane, efficiently solve the problem that is connected and installed of support rail shell, reasonable in design, the practicality height.
