Abstract
Belonging to the technical field of cranes, the utility model relates to an improvement of the prior art, in particular to a trolley-running device provided with an eccentric shaft. The trolley-running device comprises the eccentric shaft, clamp springs, bearings, bearing supports, a trolley chassis, a hanger plate, flat keys, a main driven wheel, a driving shaft, a through pin, a driving wheel, driven wheels, gaskets and an electric motor; wherein, the driving shaft is arranged on one side of the trolley chassis; one end of the driving shaft is beared by the main driven wheel; the other end of the driving shaft is beared by the driving wheel, which is driven by the electric motor; the eccentric shaft is arranged on the other side of the trolley chassis and beared by the bearings and the bearing supports; and the hanger plate and the through pin are also arranged on the trolley chassis. The trolley-running device provided with the eccentric shaft can ensure that the four wheels can always be located on a track, as a result, a trolley can run more stably, and the service lives of the wheels and the track can be effectively prolonged.
Description
Technical field
The utility model belongs to the technical field of hoisting crane, is improvements over the prior art, is specifically related to a kind of trolley travelling device that eccentric shaft is set.
Technical background
The trolley travelling device is the main accessory of starter, and its operation quality directly relates to the safety and the result of use of starter, and is most important.Current because manufacturing errors and distortion naturally, two trolley tracks on two girders of all each hoisting cranes can not be parallel fully, dolly moves on such track, is that three wheels drop on the track certainly, and a wheel is unsettled, if one of them driving wheel, so just have only a wheel drive, will cause the dolly irregular operating, can cause derailing when serious, wheel rim and track side surfaces produce friction, shorten the service life of wheel and track greatly.
The utility model content
The purpose of this utility model is to avoid above-mentioned weak point of the prior art and a kind of trolley travelling device that eccentric shaft is set of providing.This trolley travelling device eccentric shaft automatic compensation wheel height makes carriage walking steady.
The purpose of this utility model can realize by following measure:
The utility model comprises eccentric shaft, jump ring, bearing, bearing seat, trolley frame, boatswain chair, flat key, principal and subordinate wheel, imput shaft, wears pin, driving wheel, flower wheel, packing ring, motor, in trolley frame one side imput shaft is set, imput shaft one end is supported by principal and subordinate wheel, the other end is supported by driving wheel, and driving wheel is by driven by motor; At the trolley frame opposite side eccentric shaft is set, and, boatswain chair also is set on trolley frame and wears pin by bearing, bearing block support.
The utility model has following advantage compared to existing technology:
Because the utility model is that prior art is improved, and the trolley travelling device of eccentric shaft is set, and four wheels are dropped on the track all the time, carriage walking is more steady, prolongs the service life of wheel and track effectively.
