Abstract
A kind of straight stock switch point heel end connection structure of tramcar pectination track switch, including tongue and railway switch frame, the heel end of tongue has pivot, and the upper surface of pivot has first shoulder；Corresponding in railway switch frame has the second shoulder and pivot hole on the table top of pivot, and first shoulder and the second shoulder are contour；First shoulder is located at tongue inoperative side side, and the second shoulder is located at close to railway switch frame work side side；The pivot is inserted into pivot hole, and pivot is axially limited in pivot hole by the pressing plate by being arranged on first shoulder and the second shoulder, and make tongue working edge and railway switch frame inoperative between and pressing plate and when railway switch frame work between there are guard rail slots；The parallel flat segments in point of switch part inoperative Bian Weiyu railway switch frame work side form guard rail slot after tongue around the pivot pulls open between flat segments and railway switch frame work side.The utility model is to guarantee the size of space after tongue pulls open.
Description
Technical field
The utility model belongs to tramcar rail pectination turnout technology field, and in particular to a kind of tramcar pectination track switch
Straight stock switch point heel end connection structure.
Background technique
Tramcar pectination track switch is in order to save land used, by one combined type road of the end to end formation of multiple simple turnouts
Trouble, each straight stock side railway switch in position that branches off uses same model tongue and railway switch frame, and side stock railway switch is adopted except forefront trouble position
With outside structure railway switch frame similar with straight stock, remaining trouble position side stock railway switch overlap with preceding group of trouble position interference formed it is multidirectional
Railway frog.Keep practical idle space long after there is overlapping there are multiple idle spaces, and idle space due to side stock Multi-directional crossing
Degree increases, and directly to when crossing vehicle, needing tongue part in straight stock railway switch frame to serve as guard rail effect, opposite side stock Multi-directional crossing is harmful
Space is protected.Since straight stock switch point needs to serve as guard rail, rear tongue inoperative side and railway switch are pulled open to tongue
The requirement of frame space size is very high, and size Control difficulty is big after traditional elastic bendable structure deforms tongue, can not effectively control
Tongue pulls open the rear size of space.
Utility model content
The utility model provides a kind of straight stock switch point heel end connection structure of tramcar pectination track switch, to guarantee point
Rail pull open after the size of space.
The technical scheme adopted by the utility model is a kind of straight stock switch point heel end of tramcar pectination track switch connects
Binding structure, including tongue and railway switch frame, the heel end of the tongue has pivot, and the upper surface of pivot has First
Shoulder；Corresponding in the railway switch frame has the second shoulder and pivot hole on the table top of pivot, and first shoulder and the second shoulder
It is contour；The first shoulder is located at tongue inoperative side side, and the second shoulder is located at close to railway switch frame work side side；Institute
It states pivot to be inserted into pivot hole, and pivot is axially limited in pivot by the pressing plate by being arranged on first shoulder and the second shoulder
In axis hole, and make tongue working edge and railway switch frame inoperative between and pressing plate and when railway switch frame work between
There are guard rail slots；The parallel flat segments in point of switch part inoperative Bian Weiyu railway switch frame work side, work as tongue
After around the pivot pulls open, guard rail slot is formed between the flat segments and railway switch frame work side.
Corresponding point of switch part is equipped with adjustable top iron at two on the inside of the railway switch frame inoperative side.
Compared to the prior art, the utility model has the advantages that the connection of the utility model heel of switch rail using pivot
Axis structure, structure is simple, performance stablize, so that tongue pull force is become smaller, it is ensured that tongue pull open after the size of space, make side stock
Idle space existing for Multi-directional crossing obtains effective protection, ensure that travel safety.
Detailed description of the invention
Fig. 1 is the utility model structure diagram；
Fig. 2 is the utility model tongue structural schematic diagram；
Fig. 3 is structure sectional view at E-E in Fig. 1；
Fig. 4 is structure sectional view at C-C in Fig. 1；
Fig. 5 is the utility model installation site structural schematic diagram.
Specific embodiment
The utility model is described in detail in 1-5 and specific embodiment with reference to the accompanying drawing.
A kind of straight stock switch point heel end connection structure of tramcar pectination track switch, including tongue 1 and railway switch frame
2, the heel end of the tongue 1 has pivot 3, and the upper surface of pivot 3 has first shoulder 4；It is corresponding in the railway switch frame 2
There is the second shoulder 5 and pivot hole 6, and first shoulder 4 and the second shoulder 5 are contour on the table top of pivot 3；The first shoulder 4
Positioned at 1 inoperative side side of tongue, the second shoulder 5 is located at close to 2 working edge side of railway switch frame；The pivot 3 is inserted into
In pivot hole 6, and pivot 3 is axially limited in pivot hole 6 by the pressing plate 7 by being arranged in first shoulder 4 and the second shoulder 5
In, and make between 2 inoperative side of 1 working edge of tongue and railway switch frame and between 2 working edge of pressing plate 7 and railway switch frame
There are guard rail slots 8；The parallel flat segments 9 of 1 tip portion inoperative Bian Weiyu railway switch 2 working edges of frame of tongue, when
After 1 around the pivot 3 of tongue pulls open, guard rail slot 8 is formed between 2 working edge of the flat segments 9 and railway switch frame.The railway switch frame
Corresponding 1 tip portion of tongue is equipped with adjustable top iron 10 at two on the inside of 2 inoperative side of frame.
For the utility model when straight stock is opened, tongue 1 serves as the function of guard rail.And the rotation of around the pivot 3 when pulling of tongue 1,
The guard rail slot size that certifiable tongue is formed after pulling open is self-consistent, but also can accurately adjust tongue by adjustable top iron 10
Guard rail groove width after pulling open.The utility model plays guard rail by tongue inoperative side flat segments 9, by side stock Multi-directional crossing
Idle space existing for 11 is included in 9 protection scope of tongue inoperative side flat segments, improves trouble ride comfort and railway frog service life,
Guarantee traffic safety.
Above-described embodiment, the only preferred embodiment of the utility model not are used to limit the implementation model of the utility model
It encloses, therefore all equivalent variationss done with content described in the utility model claims, the utility model right should all be included in and wanted
Within the scope of asking.
