Abstract
The utility model discloses one kind to overhaul crane locomotive wheel apparatus, it includes crane end carriage, wheel is on the bent plate of end carriage, the centre of two wheels is welded with reinforcing plate on the center line of end carriage, positioned from reinforcing plate center bore hole through upper and lower cover plates and with high nut, screw mandrel passes through upper lower nut from below to up, and handwheel is arranged on the top of screw mandrel and is connected with flat key with screw mandrel.Described bore diameter is more than the 3mm of screw mandrel diameter 1, and the end of screw mandrel through lower cover is spherical in shape.This simple in construction, convenient work, the difficulty for reducing more wheel change, and it is time saving and energy saving.
Description
Technical field
A kind of maintenance crane locomotive wheel apparatus is the utility model is related to, during especially suitable for lifting machine overhauling or more wheel change
Use.
Background technology
The crane in China at present, whenever maintenance or more wheel change, the bent plate of wheel is always headed on hydraulic jack,
Wheel top to orbital plane is left, more wheel change is being carried out.So do and following problem be present,
1. the bent plate of wheel is weaker, it is easily deformed, if deformation, just influences whether the levelness of wheel and vertical
Degree, wheel is walked tiltedly or is gnawed cart track, have a strong impact on the quality of crane.
2. more wheel change in this way, maintenance personal needs to climb up in the weighing beam in workshop with heavy jack,
It is very inconvenient, very big potential safety hazard also be present.
3. the bent plate of wheel is headed on jack, jack can only occupy very big sky in the front of wheel
Between, make the maintenance replacing wheel space of natively very little smaller, increase its work difficulty.
The content of the invention
Task of the present utility model is to propose a kind of workload for reducing more wheel change, changes easy, effortless one kind
Overhaul crane locomotive wheel apparatus.
Task of the present utility model is done in such a way that it includes crane end carriage, and wheel is mounted on the bent plate of end carriage, its
It is characterised by：The centre of two wheels is welded with reinforcing plate on the center line of end carriage, is passed through from reinforcing plate center bore hole upper
Lower cover is simultaneously positioned with high nut, and screw mandrel passes through upper lower nut from below to up, handwheel be arranged on the top of screw mandrel and with flat key and
Screw mandrel connects.Described bore diameter is more than screw mandrel diameter 1-3mm, and the end of screw mandrel through lower cover is spherical in shape.
The utility model has the following effects that, this simple in construction, convenient work, reduces the difficulty of more wheel change, and save
Shi Shengli.
Brief description of the drawings
Fig. 1 is adjustable roller apparatus structure schematic diagram；Fig. 2 is Fig. 1 side view.
Drawing explanation：1st, end carriage, 2, wheel, 3, handwheel, 4, screw mandrel, 5, reinforcing plate, 6, high nut, 7, track, 8, bent plate.
Embodiment
Embodiment is described in detail with reference to the figures above, wheel 2 is assemblied on the bent plate 8 of end carriage 1, and the centre of two wheels exists
Reinforcing plate 5 is welded with the center line of end carriage, it is therefore an objective to prevent that the upper and lower cover plates local stress of end carriage is excessive and deforms cover plate, from
Reinforcing plate center bore hole is positioned through upper and lower cover plates and with high nut 6, and screw mandrel 4 passes through upper lower nut, handwheel 3 from below to up
It is connected installed in the top of screw mandrel and with flat key with screw mandrel, described bore diameter is more than screw mandrel diameter 1-3mm, and screw mandrel passes through down
The end of cover plate is spherical in shape, it is therefore an objective to reduces frictional force when screw mandrel contacts rotation with road rail level.Above description is with crane one
Structure exemplified by the wheel of side on opposite side wheel is no longer described in detail as this structure.
When that need not repair or during more wheel change, handwheel can conveniently be laid down, deserve the crane and need repairing or change
During wheel, maintenance personal need to only rotate handwheel, make screw mandrel downward, finally head on track 7 by screw mandrel end, make the wheel of crane
2 leave track, and at this moment maintenance personal can very convenient more wheel change.
Claims (2)
1. one kind maintenance crane locomotive wheel apparatus, it includes crane end carriage, and on the bent plate of end carriage, its feature exists wheel
In：The centre of two wheels is welded with reinforcing plate on the center line of end carriage, and upper and lower cover plates is passed through from reinforcing plate center bore hole
And positioned with high nut, screw mandrel passes through upper lower nut from below to up, and handwheel is arranged on the top of screw mandrel and connected with flat key and screw mandrel
Connect.
A kind of 2. maintenance crane locomotive wheel apparatus as claimed in claim 1, it is characterised in that：Described bore diameter is more than silk
Shank diameter 1-3mm, the end of screw mandrel through lower cover are spherical in shape.
