Description
Technical field
The present invention relates to the part of crane gear travelling mechanism, and in particular to a kind of horizontal wheels group.
Background technology
In the traveling mechanism of the larger traveller generally use double wheel rims of the big bridge crane of span and crane for steelworks use, wheel rim
Effect be oriented to and bear deflection operation when horizontal side force.Because in actual production, due to a variety of causes crane
Occur that deflection operation causes wheel and interorbital to produce serious abrasion, i.e., it is so-called to gnaw rail phenomenon.Due to serious wear, have
Only some months in crane wheel workpiece life-span, some steel rail for crane have to change in advance.On the other hand, deflection is run
When mechanism need to overcome bigger resistance, the bearing capacity of transmission mechanism and motor capacity are both needed to accordingly increase in the design, are
This, people seek various methods and attempt to overcome and improve above-mentioned phenomenon.
People draw if using horizontal wheels and the wheel without wheel rim in long-term production practices, gnaw rail phenomenon just not
Occur, and when deflection operation to a certain extent when, horizontal side force that horizontal wheels are born, its further deflection fortune can be prevented
OK, in addition, being rolling friction between horizontal wheels and track side surfaces, frictional resistance greatly reduces, to travelling mechanism bearing capacity and
The requirement of motor capacity then accordingly reduces.
The structure of conventional flat wheel group as Figure 1-4, is mainly used on general overhead and gantry cranes, and technology is come relatively
Say and have already fallen behind, it has following problem：
1st, structure bulky, volume is big, can not be mutually applicable with advanced lightweight bridge machine, strict to hall space requirement；
2nd, horizontal wheels top dust seal short life, dust iron wedge cause to run bad after entering, more severe patient directly results in
Horizontal wheels come off, and cause crane failure；
3rd, horizontal wheels are using the both ends for being bolted to end carriage, and installation site and form are single, and overall structure appearance and size is big, matter
Amount weight, processing, installation difficulty are big；Horizontal wheels are complicated, and part wheel shaft needs to do eccentric processing, overall to need complicated processing
Technique ensures；Horizontal wheel carrier is welded by sheet material, and appearance and size is big, and has more welding capacity, after welding, welding stress meeting
Gradually release, causes overall processing dimension to change, influences the use in later stage；Horizontal wheel carrier uses spiral shell with end connection seat
Tether and connect, the keeper such as no bolt, easily misplaced during later stage use, cause horizontal wheels to glance off, influence
Overall performance；Crane later stage addition difficulty is larger and need to transform overall；
4th, horizontal wheels are disposable mechanism, later stage damage of components or need to need integral replacing when changing, and cost is high, and time-consuming,
It is big to change difficulty；
5th, design, overall processing dimension root need to be directed to for different lifting capacities, the crane of span cart track, horizontal wheels group
Need to change according to the difference of track, can not realize exchange, standardization level is low.
The content of the invention
The technical problem to be solved in the present invention is that existing horizontal wheels can not be applied to a variety of various sizes of tracks, and
Horizontal wheels need integral replacing when damaging.
In order to solve the above technical problems, the present invention uses following technical scheme：
A kind of horizontal wheels group, including a pair of horizontal wheels, a pair of slide-bars and a pair of fixed blocks, the upper end interval of a pair of fixed blocks are preset
Distance is set, and has the slideway in gap among composition；The center of a pair of horizontal wheels is removably attached on a pair of slide-bars respectively, and one
Slide-bar is arranged on the slideway, the distance between a pair of slide-bars are adjustable.
Two fixed blocks are oppositely arranged, and two relative faces of fixed block are provided with first step；The both sides of slide-bar upper end are set
Second step is equipped with, second step is slideably stuck on first step.
Locating piece is additionally provided with the slideway, the both sides of locating piece are provided with the 3rd step, and the 3rd step is fixed on
On one step；Between two slide-bars, two slide-bars are fixed on locating piece locating piece by stay bolt, locating piece and two
The first pad is provided between slide-bar, the first pad includes more than one.
Stay bolt is fixed on locating piece after crossing slide-bar along slideway direction, is set between stay bolt head and slide-bar outside
There is the second pad.
Second pad includes more than one.
The centrally disposed cylinder roller bearing of the horizontal wheels, cylinder roller bearing center are removably solid with the slide-bar
Fixed connection.
The cylinder roller bearing upper end sets closure.
Relative to prior art, technique effect of the invention is that the present invention is by being arranged between slide-bar and locating piece
The distance between adjustable two slide-bars of pad, and then the distance between adjustable a pair of horizontal wheels, therefore it is applicable to difference
The track of size.The center of horizontal wheels is removably attached on slide-bar, and horizontal wheels can only change damage part when damaging, and is saved
Maintenance cost.
