In the operation of subway, with monorail trolley, track flat car, contact net aerial ladder, rail checking instrument etc. (with
Under be referred to as rail row dolly) quantity of upkeep operation is more, the arrangement of the running track of rail row dolly similar to track for a train.Rail row
Dolly, which can exist, to be slided down by track switch railway frog, climbs up frog or produce the potential safety hazards such as inclination, and then causes volume to maintenance work
Outer human and material resources waste, it is also possible to cause failures such as " red bands ", or even cause the accidents such as personal injury.Moreover, rail row dolly
The other sizes such as much smaller than train of wheel rim size, the wheel back of the body it is also different from Train wheel, comparatively, rail row dolly falls
The risk in road is bigger.
Utility model content
The purpose of this utility model is to provide a kind of used trouble device of rail row dolly, effectively to eliminate harmful sky of track switch
Between.
To achieve the above object, the utility model adopts the following technical scheme that：The used trouble device of rail row dolly, including first is solid
Determine block, gib block, the second fixed block, the first opening up neck, the second neck, gib block are arranged with the first fixed block
One end straight end and to be installed in the first neck or the second neck, the other end of gib block be cutting end, and cutting end, which has, pastes
Tightly two bayonet sockets, the part at the cutting end of gib block are arranged with the cutting plane in throat trackside face, the both sides of the second fixed block
It is stuck between throat rail and bayonet socket, the first fixed block is positioned over the tip location of frog centre when in use, and gib block supplies car
The bending angle for taking turns the side of walking is adapted with frog angle.
Further, the entity part between the first neck and the second neck of the first fixed block is dividing plate, dividing plate
Width gradually broadens from the direction of frog centre towards the direction at gib block cutting end.
Further, the bottom surface of the first fixed block is isosceles trapezoid.
Further, the bottom surface of the second fixed block is isosceles trapezoid.
Further, the entity part between two bayonet sockets of the second fixed block is isosceles trapezoid block.
Further, the cross section of the first fixed block is in " mountain " font.
Further, the cross section of the second fixed block is in "convex" shaped.
Further, the cutaway portion of gib block is non-wide section, and the straight line portion of gib block is wide section.
The beneficial effects of the utility model：When the used trouble device of the utility model rail row dolly is applied in orbit, by first
Fixed block is placed at the tip of frog centre, and the second fixed block card is placed between two tracks, and gib block both ends are according to correct side
To being attached separately in the neck of the first fixed block, the bayonet socket of the second fixed block.Have dolly by when, it is necessary to during lane change, be oriented to
Bar plays a part of curve rail, crosses the transitional function for branching off and guiding and load being provided when device enters frog for dolly along straight bent stock, makes
Its smooth safety frog centre, this new mistake trouble device can effectively eliminate idle space, ensure the reliable of trolley travelling,
Failure, accident are less likely to occur.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, every other embodiment that those of ordinary skill in the art are obtained all belongs to
In the scope of the utility model protection.
Embodiment：
As Figure 1-Figure 5, the used trouble device of rail row dolly described by the present embodiment, including the first fixed block 1, guiding
Bar, the second fixed block 2 and gib block 3.First fixed block 1 be provided with the first opening up neck 11, the second neck 12, first
The entity part between the first neck and the second neck of fixed block 1 is dividing plate 13, and the width of dividing plate 13 is from the side of frog centre 5
Gradually broadened to towards the direction at gib block cutting end.First neck 11, the second neck 12 are symmetrical arranged, and are guide groove.The
One fixed block, the bottom surface of the second fixed block are isosceles trapezoid.First fixed block 1 is positioned over the tip of frog centre 5 when in use
Position, the second fixed block 2 are placed on the near middle of idle space.The both sides of second fixed block 2 are arranged with two bayonet sockets 21.The
The cross section of one fixed block is in " mountain " font.The cross section of second fixed block is in "convex" shaped.Second fixed block blocks positioned at two
Entity part 22 between mouthful is isosceles trapezoid block.
One end of gib block 3 is straight end 33 and is installed on the second neck 12, and the other end of gib block 3 is cutting end 31, is cutd open
Cut end has the cutting plane 32 being adjacent in the side of throat rail 4, and the part at the cutting end of gib block is stuck in throat rail and bayonet socket
Between, the bending angle of the side for wheel walking of gib block is adapted to the frog angle of frog centre 5.Gib block 3 is placed on
In corresponding bayonet socket in the respective card slot of one fixed block, the second fixed block, after assembling so that continuously coincide with frog path, be
Rail row dolly provides the transitional function being oriented to load when entering frog along straight bent stock, make its smooth safety frog centre.Fig. 5
In, be rail labeled as 6, shown in figure for simple turnout.
The cutaway portion of gib block is non-wide section, and the straight line portion of gib block is wide section.
Often with the different set of track switch P50-7, P60-9 track switch frog angle, its size is different according to parking lot for first fixed block
Two pieces, selected when being needed for operation.Second fixed block can be configured as being applicable P50-7, P60-9 track switch.The chi of gib block
