Part is hinged, and the other end is hinged with polar crane bridge girder 1 constitutes longitudinal oblique pull triangular structure；
Horizontal support 2.1 is the support member of support bar 2.5 horizontal direction, before horizontal support 2.1 one end and support bar 2.5
End portion is hinged, the other end and the hinged composition of polar crane bridge girder 1 horizontal oblique pull triangular structure；
Horizontal guide sheave 2.3 includes: chassis group 2.301, hinged block 2.302, hinge 2.303, antivibrator 2.305, axle sleeve
Seat 2.306 and jackshaft 2.308；
Sleeve block 2.306 is fixed on support bar 2.5 forward end, and the axis hole extension of sleeve block 2.306 is embedded in
In support bar 2.5；
Jackshaft 2.308 is assemblied in the axis hole of sleeve block 2.306, and with sleeve block 2.306 by arranging feather key
2.309 realize axial stretching motion；
Hinged block 2.302 is fixed on jackshaft 2.308 external part end, and between hinged block 2.302 and sleeve block 2.306
It is provided with antivibrator 2.305；
Wherein, all by even between sleeve block 2.306 and support bar 2.5 and between hinged block 2.302 and antivibrator 2.305
Connecting bolt 2.304 assembles；
Hinge 2.303 is passed through hinged, it is ensured that two wheels of chassis group are subject between chassis group 2.301 and hinged block 2.302
Power is consistent, and Impact direction is along the direction of support bar 2.5；
Hinge 2.303 is eccentric shaft, by rotating this eccentric shaft, it is possible to adjust chassis group 2.301 wheel tread and level
Distance between track.
Further, the quantity of antivibrator 2.305 is more than or equal to 2.
Further, replaceable adjusting pad 2.307 it is provided with between hinged block 2.302 and support bar 2.5.
Wherein, the assembling form that support bar 2.5 can be parallel with polar crane bridge girder 1 according to the actual requirements, can
Select the first single armed parallel construction as it is shown in figure 5, the second be multi-arm oblique pull parallel construction as shown in Figure 6.
The operation principle of the present invention of employing technique scheme:
Horizontal guide sheave 2.3 is supported by support bar 2.5, and horizontal support 2.1 and bearing diagonal 2.4 are by support bar 2.5 end
Couple together with girder, it is ensured that support bar 2.5 end is a stable structure, and horizontal guide sheave 2.3 is arranged on support bar 2.5
End, a set of horizontal guide sheave of each installation on four angles of polar crane, it is achieved the horizontally-guided to polar crane, hinge
2.303 is a kind of eccentric shaft, by rotating this eccentric shaft, it is possible to adjust between chassis group 2.301 wheel tread and horizontal rail
Distance.
The horizontal guide sheave bridge-frame end-beam 3 side horizontal wheels wheelspan A of this kind of form has relatively remote, because polar crane
Horizontal wheel load is relevant to this distance, and distance is the biggest, and horizontal wheel load is the least, the most favourable to polar crane equipment, and this device uses
Three bars support, i.e. support bar 2.5, horizontal support 2.1 and bearing diagonal 2.4 3 bar supports, and three bar supporting constructions can make horizontal wheels
As far as possible away from girder, increase horizontal wheels wheelspan to greatest extent.
When the wheel tread pressurized of the chassis group 2.301 of horizontal wheels, transfer force to hinged block by hinge 2.303
On 2.302, hinged block 2.302 is oppressed antivibrator 2.305 and is deformed, and antivibrator 2.305 plays cushioning effect, when the chassis of horizontal wheels
After the pressure of the wheel tread of group 2.301 removes, antivibrator 2.305 restores to the original state.In the process that antivibrator 2.305 is compressed
In, the jackshaft 2.308 being fixed on hinged block 2.302 slides in sleeve block 2.306, simultaneously as feather key 2.309
Effect, chassis group 2.301 will not rotate around jackshaft 2.308；Adjusting pad 2.307 causes horizontal wheels for regulation because of alignment error
Time improper with orbit gap, adjust gap and use.
To sum up, the present invention passes through new structural design, it is ensured that support bar leading section is (relative to polar crane crane span structure master
Beam) can stably stretch out, structural strength is enough, and the design further through horizontal guide sheave realizes a spacing scalable, runs
The horizontally-guided wheel construction that buffer capacity is strong, further ensures that horizontal guide sheave coordinates surely with polar crane horizontal rail 6
Fixed, horizontally-guided is stable.
The above, be only presently preferred embodiments of the present invention, and the present invention not makees any pro forma restriction, though
So the present invention is disclosed above with preferred embodiment, but is not limited to the present invention, any technology people being familiar with this specialty
Member is in the range of without departing from technical solution of the present invention, when the technology contents of available the disclosure above makes a little change or is modified to
