Description
Technical field
The present invention relates to the components of lifting equipment operating mechanism, and in particular to a kind of horizontal wheels group.
Background technique
Double wheel rims, wheel rim are generallyd use in the traveling mechanism of the larger traveller of the big bridge crane of span and crane for steelworks use
Effect be guiding and bear deflection operation when horizontal lateral force.In actual production, because of crane due to various reasons
Will appear deflection operation causes wheel and interorbital to generate serious abrasion, i.e., so-called to gnaw rail phenomenon.Due to serious wear, have
Only some months, some steel rail for crane have to replace in advance the crane wheel workpiece service life.On the other hand, deflection is run
When mechanism need to overcome bigger resistance, the bearing capacity and motor capacity of transmission mechanism are both needed to increase accordingly in the design, are
This, people seek various methods and attempt to overcome and improve above-mentioned phenomenon.
People obtain in long-term production practices if gnawing rail phenomenon just not using horizontal wheels and without the wheel of wheel rim
It will appear, and when deflection is run to a certain extent, the horizontal lateral force that horizontal wheels are born, its further deflection fortune can be prevented
Row, in addition, being rolling friction between horizontal wheels and track side surfaces, frictional resistance is greatly reduced, to operating mechanism bearing capacity and
The requirement of motor capacity then accordingly reduces.
The structure of conventional flat wheel group is as shown in Figs 1-4, is mainly used on general overhead and gantry cranes, and technology is come relatively
It says and has already fallen behind, there are the following problems:
1, structure bulky, volume is big, can not require hall space stringent with advanced lightweight bridge machine Xiang Shiyong；
2, the horizontal wheels top dust seal service life is short, and dust iron wedge causes to run bad after entering, and more serious person is direct
Cause horizontal wheels to fall off, causes crane failure；
3, horizontal wheels benefit is fixed by bolts to the both ends of end carriage, installation site and in the form of a single, overall structure outer dimension
Greatly, quality weight, processing, installation difficulty are big；Structure is complicated for horizontal wheels, and part wheel shaft needs to do eccentric processing, integrally needs complexity
Processing technology guarantee；Horizontal wheel carrier is welded by plate, and outer dimension is big, and has more welding capacity, after welding, welding
Stress can gradually discharge, and whole processing dimension is caused to change, and influence the use in later period；Horizontal wheel carrier and end connection seat
It is connected by screw bolts, the locating pieces such as no positioning bolt easily misplace in later period use process, cause horizontal wheels to occur inclined
Tiltedly, whole service performance is influenced；Crane later period addition difficulty is larger and need to be transformed to whole；
4, horizontal wheels are disposable mechanism, and later period damage of components or while needing replacing need integral replacing, at high cost, time-consuming
Long, replacement difficulty is big；
5, for the crane of different lifting capacities, span cart track, horizontal wheels group need to be for design, whole processing ruler
The very little difference according to track needs to change, and cannot achieve exchange, and standardization level is low.
Summary of the invention
The technical problem to be solved by the present invention is to, existing horizontal wheels can not be suitable for a variety of various sizes of tracks, and
Horizontal wheels need integral replacing when damaging.
In order to solve the above technical problems, the invention adopts the following technical scheme:
A kind of horizontal wheels group, including a pair of of horizontal wheels, a pair of of slide-bar and a pair of of fixed block, the upper end interval of a pair of of fixed block
Pre-determined distance setting, the intermediate slideway for having gap of composition；The center of a pair of of horizontal wheels is removably attached to a pair of of slide-bar respectively
On, a pair of of slide-bar is arranged on the slideway, and the distance between a pair of of slide-bar is adjustable.
Two fixed blocks are oppositely arranged, and two opposite faces of fixed block are provided with first step；The two sides of slide-bar upper end are set
It is equipped with second step, second step is slideably stuck on first step.
Locating piece is additionally provided on the slideway, the two sides of locating piece are provided with third step, and third step is fixed on
On one step；Locating piece is located between two slide-bars, and two slide-bars are fixed on the positioning block by stay bolt, locating piece and two
The first gasket is provided between slide-bar, the first gasket includes more than one.
Stay bolt along slideway direction cross slide-bar after be fixed on the positioning block, on the outside of stay bolt head and slide-bar between be arranged
There is the second gasket.
Second gasket includes more than one.
Cylinder roller bearing is arranged in the center of the horizontal wheels, and cylinder roller bearing center and the slide-bar are removably solid
Fixed connection.
Sealing cover is arranged in the cylinder roller bearing upper end.
Compared with the existing technology, technical effect of the invention is that the present invention is by being arranged between slide-bar and locating piece
Gasket can adjust the distance between two slide-bars, and then the distance between adjustable a pair of of horizontal wheels, therefore be applicable to difference
The track of size.The center of horizontal wheels is removably attached on slide-bar, and horizontal wheels can only replace damage component when damaging, and is saved
Maintenance cost.
