Description
Technical field
The invention belongs to technical field of crane equipment, and in particular to a kind of horizontal wheel apparatus of balanced type and monkey.
Background technique
At harbour when the operation of bridge monkey, because trolley span is bigger, rail is gnawed when trolley travelling in order to prevent,
Usual single wheel is not provided with wheel rim, and horizontal roller device is arranged at the wheel of the other side, with guarantee trolley along track even running,
As shown in Figure of description 1-3.
In above-mentioned set-up mode, horizontal roller 11 is used to undertake the lateral force of monkey, when monkey is inclined
Leave the right or normal track 12 trend it is very strong when, horizontal roller 11 can bear biggish lateral force, and provide deflection counter-force to guarantee crane
Trolley is run along rail.Therefore for horizontal roller 11 as the important spare part in trolley travelling, safety and reliability are particularly significant.
When the speed of monkey is larger or the straightness of track 12 is poor, horizontal roller 11 can bear biggish
, easily there is horizontal breaking of axle, horizontal wheels bearing damage in high-strength impact load caused by lateral force or uneven straight rail, or
It situations such as person's horizontal wheels abnormal sound, is brought great potential safety hazard to the safe operation of monkey.
Meanwhile horizontal roller should keep setting gap between track when in use, when horizontal roller or path wear
Afterwards, it needs quickly to adjust horizontal roller position so that gap meets sets requirement.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of horizontal wheel apparatus of balanced type and monkey,
It is able to solve the problem of horizontal wheels are subjected to larger lateral force or shock loading and cause horizontal breaking of axle.
The present invention adopts the following technical solutions: a kind of horizontal wheel apparatus of balanced type, including being symmetrically disposed on track two sides

Rotation axis using special eccentric shaft as idler wheel in idler wheel assembly, eccentric shaft monkey work when not
It rotates, it can be by rotation eccentric adjusting lid come so that eccentric shaft turns are certain when needing to adjust idler wheel with orbit gap
Angle.
Further, the gap between the idler wheel and track is 3-5mm.
Further, the upper end of the balancing stand be equipped with mounting hole, the eccentric shaft pass through mounting hole after with eccentric adjusting lid
It is fixedly connected, the eccentric adjusting lid and balancing stand the upper surface bolt hole uniformly distributed along mounting hole axis respectively, it is described eccentric to adjust
Section lid is bolted to connection with balancing stand.
By way of being uniformly arranged bolt hole on eccentric adjusting lid and balancing stand, it can pass through when not installing bolt
Rotation eccentric adjusting lid comes so that different bolts hole are aligned, so that the distance between eccentric shaft turns axis and track occur
Variation, is installed on gap between the idler wheel and track on eccentric shaft and changes.
Further, the upper end of the mounting bracket is fixedly connected with end carriage, and lower end is rotatablely connected by hinged shaft and balancing stand.
Further, the upper end of the eccentric shaft is equipped with grease fitting.
Further, lubricant passage way is equipped in the eccentric shaft.
By the way that special grease fitting and lubricant passage way is arranged, the contact between eccentric shaft, bearing and idler wheel can be made
Face is lubricated, and can be improved the stationarity of idler wheel rotation.
A kind of monkey is not provided with balanced type horizontal wheels, other side vehicle at the single wheel of the monkey
Balanced type horizontal wheel apparatus is set at wheel.
Compared with prior art, the beneficial effects of the present invention are:
The present invention in the middle part of the balancing stand with mounting rack hingedly, balancing stand both ends connect respectively with idler wheel assembly by the way of shape
At " equalizer bar " formula structure, each balancing stand can turn an angle along hinged shaft, when the track contacted with idler wheel assembly
When there is not straight phenomenon, and the idler wheel assembly stress of rail contact and balancing stand is rotated, i.e., with rail contact
Idler wheel assembly position changes with track, impacts and carries caused by can reduce the poor wheel apparatus horizontal wheels of track straightness
Lotus.
When needing to adjust the gap between idler wheel and track, demounting bolt can be passed through and rotate the side of eccentric adjusting lid
Formula makes eccentric shaft turns certain angle, and eccentric shaft turns make eccentric shaft lateral surface that position occur by the idler wheel that bearing connects
Change, the gap changed between idler wheel and track that can be quantified.
