Description
Technical field
The utility model belongs to mine narrow gauge railway line materials technical field, relates in particular to a kind of narrow gage single switch device.
Background technology
Narrow gauge track switch is an important component part of building on the narrow gauge railway circuit.Rolling stock moves on rail track, often need enter or cross another circuit from a circuit, and this is also the same with standard gage railway, be by the connection of circuit with intersect equipment and realize.The connection of circuit with intersect the basic pattern of equipment and can be divided into three kinds, both track switch class, fixing class and track switch and the fixing combined crosswise class of intersecting.Their kind is a lot, and is also very complicated.The railway switch that adopts in the transportation of mine narrow gauge railway is the narrow gauge track switch that 43kg/m (or below 43kg/m) rail is made at present.Along with industrialized great development, the big steel mill of each of China has not produced the rail of 43kg/m (or 43kg/m is following).Present newly-built mine narrow gauge railway transports and has now the rail that can not adopt 43kg/m (or 43kg/m is following) in the narrow gauge railway transportation transformation of mine, can only be adopted as the 50kg/m rail.And adopt the 50kg/m rail not have corresponding narrow gauge railway track switch.
Summary of the invention
Be the 50kg/m rail at the railway that adopts in the transportation of present mine narrow gauge railway, and there is not the present situation of narrow gauge switch apparatus, the utility model proposes a kind of narrow gage single switch device, adopt the 50kg/m rail, gauge is 900mm, can solve existing locomotive and enter or cross another circuit, carry out safety and travel smoothly from a circuit.
The purpose of this utility model is achieved through the following technical solutions:
Narrow gage single switch device of the present utility model, comprise stock rail, railway switch, railway frog and coupling part between the two, it is characterized in that described stock rail is made up of straight rail section-bend section-lower and straight track section on straight rail in right side and the left side, described railway switch is by the right side tongue that is located at the stock rail inboard, the left side tongue, the right side bend that is connected of right side tongue therewith, the straight rail in left side that tongue is connected is therewith formed, described railway frog is by the wing rail that is connected with the right side bend with the straight rail in described left side respectively, the fork heart that is located at this wing rail lower inside is formed, and lower and straight track section inboard and straight rail inboard, right side about described wing rail are established a guard rail respectively.
The wing rail upstream end in the described fork heart outside is connected with bend offset direction outside single track with described straight rail craspedodrome direction single track respectively, rolls end away from along fork heart direction opening.
Described railway frog two path working edges are that heart rail two working edges intersect the formed angle of cut less than the right angle.
Interval iron and splice bar are adopted in described coupling part, and whole narrow gage single switch is fixed on the sleeper of railway bed by railway spike.
The radius of curvature of described bend section 4 is 30m.
Described frog length is 2450mm, and central body of frog is fixed on the big base plate.
The tongue that described tongue, straight rail, bend, guard rail, the fork heart, wing rail are made by the 50kg/m rail, straight rail, bend, guard rail, the fork heart, wing rail.
Railway switch is the equipment of pilot engine vehicle heading, mainly contains two stock rails, two tip of a root rails, interval iron, various backing plate and connected component and forms.Wherein tongue is the strength member in the railway switch, and tongue is an end of rail to be planed into pointed, makes it closely connected with the working edge of stock rail, and the swing of tongue utilizes switch machine to finish.
Railway frog is to make wheel rim be crossed the equipment of another strand rail by one rail, be positioned at the side line and the main track rail intersection of track switch, in simple turnout, railway frog two path working edges (heart rail two working edges) intersect the formed angle of cut less than the right angle, so also claim end frog.Because the requirement of wheel walking, making railway frog form both sides is wing rail, middle special structure form for the fork heart, and the front portion of wing rail plays the support wheel operation, and the rear portion plays a part the guide car wheel.Minimum range between two wing rails is a throat of frog.In order to reduce to pitch the wearing and tearing of the heart, the guard rail by both sides makes the wheel and the friction of the fork heart be kept to minimum.
The utility model has satisfied the narrow gauge railway transportation of newly-built mine and had the mine transportation now transforms the needs that adopt the corresponding narrow gauge railway track switch of 50kg/m rail.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Further specify the specific embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 1, narrow gage single switch device of the present utility model, comprise stock rail, railway switch, railway frog and coupling part between the two, it is characterized in that described stock rail is made up of 7 of straight rail section 1-bend section 4-lower and straight track sections on straight rail 8 in right side and the left side, described railway switch is by the right side tongue 9 that is located at the stock rail inboard, left side tongue 2, the right side bend 10 that is connected of right side tongue 9 therewith, the straight rail 3 in left side that tongue 2 is connected is therewith formed, described railway frog is by the wing rail 5 that is connected with right side bend 10 with the straight rail 3 in described left side respectively, the fork heart 12 that is located at these wing rail 5 lower inside is formed, and establishes a guard rail 6 respectively in lower and straight track section 7 inboards and straight rail 8 inboards, right side of described wing rail about 5,11.
