Abstract
The utility model discloses a kind of adjustable wheel group of end carriage, it comprises an end carriage body, at least one pair of wheel, and described wheel is all connected with a wheel shaft, and described wheel shaft is equipped with a pair self-aligning roller bearing; This end carriage body is equipped with the eccentric bearing block with described self-aligning roller bearing adaptation; Described eccentric bearing block is equipped with one for rotating the regulating block of this eccentric bearing block.When rail phenomenon gnawed by wheel and track, reach the object of eccentric rotation axis bearing by rotating regulating block, due to eccentric effect, there is horizontal deflection in wheel shaft, thus band motor car wheel deflection certain angle, make it again with track keeping parallelism, effectively correct gnaw rail phenomenon.Compared to other methods of adjustment, adjustable wheel group use more save time, laborsaving, can allow within the shortest time shop logistics transport with lifting normal operation.
Description
Technical field
The utility model relates to crane field, particularly a kind of adjustable wheel group of end carriage.
Background technology
Crane and dolly are in operational process, and wheel rim contacts with track side surfaces, produce horizontal lateral thrust, cause the frictionalwear of wheel rim and track, are commonly referred to and gnaw rail.The desirable running condition of hoisting crane should be that all wheel tracks are done to run without slippage in orbit, and wheel rim does not contact with the track of its operation, and namely wheel rim keeps certain gap with wheel road.In fact for a certain reason, in the process of moving, the wheel rim of wheel contacts with track hoisting crane by force, causes and gnaws rail.
If hoisting crane has occurred gnawing rail phenomenon, the service life of wheel and track can be reduced.Gnaw rail and cause that wheel and track are mandatory to be contacted, the phase mutual friction of both aggravations, can cause the metal peeling of wheel rim and track side surfaces and the outside buckling deformation of wheel rim, thus accelerate the destruction of wheel and track, reduce service life time serious.
In addition, add running resistance, force service meter and the long-term overload operation of transmission device, the consequence burning out electrical motor or twist off transmission shaft may be caused.
In addition, during hoisting crane work, noise becomes large, vibration aggravation, infringement house beam structure.Hoisting crane is gnawed rail and must to be in operation the horizontal side force of generation, makes mill construction bear additional transverse load and suffer damage in various degree.
More seriously hoisting crane climbs rail suddenly under steam, easily causes great equipment, human casualty accident.
If temporarily can solve the problem by the method for shaping, but a large amount of human and material resources and financial resources may be wasted.
Utility model content
The technical problems to be solved in the utility model is that the life-span in order to overcome wheel and track in prior art is lower, electrical motor and transmission shaft are easily impaired, and hoisting crane operating noise is large, infringement house beam structure and easily cause the defect of equipment and personnel casualty accidents, provides a kind of adjustable wheel group of end carriage.
The utility model solves above-mentioned technical matters by following technical proposals:
An adjustable wheel group for end carriage, it comprises an end carriage body, at least one pair of wheel, and described wheel is all connected with a wheel shaft, and its feature is, described wheel shaft is equipped with a pair self-aligning roller bearing; This end carriage body is equipped with the eccentric bearing block with described self-aligning roller bearing adaptation; Described eccentric bearing block is equipped with one for rotating the regulating block of this eccentric bearing block.
Wherein, described end carriage body and a girder are rigidly connected.
Wherein, this regulating block is provided with a deep-slotted chip breaker, and on described end carriage body, the position relative with this deep-slotted chip breaker is provided with a bolt, and this bolt is through this deep-slotted chip breaker; This regulating block also vertically wearing one for locking the lock screw of this regulating block, pressing on this end carriage body during the locking of this lock screw.
Wherein, between described wheel and the described self-aligning roller bearing of correspondence, a pad is equipped with.
Wherein, between described eccentric bearing block and this end carriage body, one deck seal ring is provided with.
Wherein, the center of circle of described eccentric bearing block and the center of circle deviation in the horizontal direction of described wheel are 1.5mm.
On the basis meeting this area general knowledge, above-mentioned each optimum condition, can combination in any, obtains each preferred embodiments of the utility model.
Positive progressive effect of the present utility model is: when rail phenomenon gnawed by wheel and track, the object of eccentric rotation axis bearing is reached by rotating regulating block, due to eccentric effect, there is horizontal deflection in wheel shaft, thus band motor car wheel deflection certain angle, make it again with track keeping parallelism, effectively correct gnaw rail phenomenon.Compared to other methods of adjustment, adjustable wheel group use more save time, laborsaving, can allow within the shortest time shop logistics transport with lifting normal operation.

Detailed description of the invention
Mode below by embodiment further illustrates the utility model, but is not therefore limited among described scope of embodiments by the utility model.
As shown in Fig. 1 ~ Fig. 5, the adjustable wheel group of the end carriage in the present embodiment comprises two wheels 1, each wheel 1 all wears a wheel shaft 2.Be equipped with a self-aligning roller bearing 8 at the two ends of every root wheel shaft 2, end carriage body 3 is then provided with the eccentric bearing block 7 with this self-aligning roller bearing 8 adaptation, this eccentric bearing block 7 is arranged on this end carriage body 3.Wheel shaft 2 is arranged on this end carriage body 3 by described self-aligning roller bearing 8 and eccentric bearing block 7.The center of circle of described eccentric bearing block 7 and the center of circle of described wheel 1 deviation are in the horizontal direction 1.5mm.One deck seal ring 10 is provided with between this eccentric bearing block 7 and end carriage body 3.A pad 12 is equipped with between wheel 1 and self-aligning roller bearing 8.
Wherein, the eccentric bearing block 7 on the right side of wheel 1 is arranged a stifle 9, the eccentric bearing block 7 on right side is provided with a logical lid 13.Eccentric bearing block 7 on the left of this wheel 1 is provided with one for rotating the regulating block 4 of this eccentric bearing block 7.This regulating block 4 is provided with a deep-slotted chip breaker 5, and on described end carriage body 3, the position relative with this deep-slotted chip breaker 5 is provided with a bolt 6, and this bolt 6 is through this deep-slotted chip breaker 5.This regulating block 4 also vertically wearing one for locking the lock screw 11 of this regulating block 4, pressing on this end carriage body 3 when this lock screw 11 is locked.
Again as shown in Figures 4 and 5, when rail phenomenon gnawed by track (not shown) and wheel 1, unclamp this lock screw 11, regulating block 4 is rotated along this deep-slotted chip breaker 5, eccentric bearing block 7 rotates under the drive of regulating block 4, and because eccentric effect wheel shaft 2 there will be a certain amount of horizontal deflection, band motor car wheel 1 deflects certain angle, make it again to keep balancing with track, thus effectively rail phenomenon is gnawed in correction.
