Abstract
The utility model discloses a simple turnout used for a coal mine tunnel. The simple turnout comprises a single turnout body composed of a straight stock rail, a curved stock rail, a straight connecting rail, a curved connecting rail, a point rail, a protection rail and a turnout machine core. The wing rail throat position of the turnout machine core is an arc transition section, and the frog angle of the turnout is eighteen degrees and fifty five minutes. The length of the tightly attached face between the point rail and the straight basic rail is 400 nm-450 nm, and the length of the tightly attached face between the rail bottom of the point rail and a roadbed is 600 mm-700 mm. The curved stock rail is of a three-section bent structure. The two ends of the protection rail are of a single bent structure. The simple turnout is designed for coal mine tunnel rail transportation, thereby having the advantages of being safe and reliable of a common turnout and further having the advantages of being simple to machine, low in weight and convenient to construct and lay of a simple turnout.
Description
Technical field
The utility model relates to rail transport connection track switch, especially relates to coal mine roadway simple turnout.
Background technology
Coal mine roadway rail transport is subject to the restriction of workplace, require tunnel with simple turnout possess length short, turn half through little feature, and the construction that will be convenient in tunnel is laid.Therefore, conventional standard points is unsuitable for tunnel rail transport use.At present, for tunnel rail transport, adopt simpleturnout, traditional simpleturnout is divided into heart rail, tongue, chassis three parts more, heart rail is welded on chassis plate, tongue is bolted on chassis with one, and for guaranteeing swinging of tongue, this bolt is without pretightning force.Like this, heart rail and tongue link together indirectly by bolt, chassis.The deficiency of its existence is 1, because the fixed screw of tongue is without pretightning force, the activity space of tongue fixed end is too large, mine car during by track switch tongue very easily left and right is crooked, cause derailing of mine car; Tongue fixed end rail neck and the flange of rail are because material cutting is too many, and strength decreased, is very easily out of shape or fracture, causes track switch damage to scrap.2, mine car is when the tongue fixed end, and due to its distortion or fracture, tongue easily takeoffs or perk, the go-cart personnel legs and feet that easily injured by a crashing object, wound.3,, because rail adopts wooden sleeper more, tongue and fixed track contact point curve place gauge are easily large by mine car support, exist and cause derailing of mine car unsafe factor.
Summary of the invention
The utility model object is to provide a kind of coal mine roadway simple turnout.
For achieving the above object, the utility model is taked following technical proposals:
Coal mine roadway simple turnout described in the utility model, the simple turnout body that comprise by straight stock rail, bent stock rail, direct-connectedly integrate with, bent connecting rail, tongue, guard rail, track switch movement forms; The wing rail throat of described track switch movement is arc transition section, the frog angle of track switch be 18 ° 55 '; Described tongue is 400mm-450mm with the closely connected face length degree of straight stock rail, and the closely connected face length degree of the flange of rail of tongue and roadbed is 600mm-700mm; Described bent stock rail is three sections of bending structures; The both ends of described guard rail are single bending structure.
The utility model advantage is to design for coal mine roadway rail transport, makes it possess that regular track switch is safe and reliable possesses again the advantage that simpleturnout processing is simple, quality is light, constructability is laid.The wing rail throat of track switch movement is set to arc transition section, and the frog angle of track switch elects 18 ° 55 as ', reduced the idle space of track switch trouble core, improved the safety that vehicle is crossed trouble.The both ends of guard rail are set to single bending structure, cancel the chamfering at existing guard rail two ends, make to process more convenient.The closely connected face length degree of the flange of rail of tongue and roadbed is 600mm-7000mm, has saved using and laying of iron brace.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, coal mine roadway simple turnout described in the utility model, the simple turnout body that comprise by the straight stock rail 1 of long 4000mm, bent stock rail 2, direct-connectedly integrate with 3, bent connecting rail 4, tongue 5, guard rail 6, track switch movement 7 forms; The wing rail throat of described track switch movement 7 is arc transition section 8, the frog angle of track switch be 18 ° 55 '; Described tongue 5 is 400mm with the closely connected face length degree of straight stock rail 1, and the closely connected face length degree of the flange of rail of tongue 5 and roadbed is 650mm; Described bent stock rail 2 is three sections of bending structures; The both ends of described guard rail 6 are single bending structure.
