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；Point of switch part inoperative is forming guard rail slot after tongue around the pivot pulls open for the flat segments parallel with when railway switch frame work between flat segments and railway switch frame work side.The present invention is to guarantee the size of space after tongue pulls open.
Description
Technical field
The invention belongs to tramcar rail pectination turnout technology fields, and in particular to a kind of straight stock of tramcar pectination track switch
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.
Summary of the invention
The present invention provides a kind of straight stock switch point heel end connection structure of tramcar pectination track switch, to guarantee that tongue is pulled
The size of space after opening.
The technical scheme adopted by the invention is that: a kind of straight stock switch point heel end connection knot of tramcar pectination track switch
Structure, including tongue and railway switch frame, the heel end of the tongue has pivot, and the upper surface of pivot has first shoulder；Institute
Stating has the second shoulder and pivot hole on the table top for corresponding to pivot in railway switch frame, and first shoulder and the second shoulder are 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；The pivot
Axis 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
In, and make tongue working edge and railway switch frame inoperative between and pressing plate and when railway switch frame work between stay
There is guard rail slot；Point of switch part inoperative is while for the flat segments parallel with when railway switch frame work, when tongue is around pivot
After axis 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 invention has the benefit that heel of switch rail of the present invention connection uses pivoting 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 Multi-directional crossing
Existing idle space obtains effective protection, ensure that travel safety.

Fig. 2 is tongue structural schematic diagram of the present invention；
Fig. 3 is structure sectional view at E-E in Fig. 1；
Fig. 4 is structure sectional view at C-C in Fig. 1；

Specific embodiment
The present invention is described in detail for 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 1 tip portion inoperative side of tongue is the flat segments 9 parallel with 2 working edge of railway switch frame, 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 present invention 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, it can protect
The guard rail slot size that card tongue is formed after pulling open is self-consistent, but also can accurately adjust tongue by adjustable top iron 10 and pull open
Guard rail groove width afterwards.The present invention plays guard rail by tongue inoperative side flat segments 9, will be existing for the stock Multi-directional crossing 11 of side
Idle space is included in 9 protection scope of tongue inoperative side flat segments, improves trouble ride comfort and railway frog service life, guarantees driving
Safety.
Above-described embodiment, only presently preferred embodiments of the present invention, the practical range being not intended to limit the invention, thus it is all with
The equivalent variations that content described in the claims in the present invention is done should all be included within scope of the invention as claimed.
