Abstract
The utility model discloses an electric suspended type trolley for skidproof running of a crane. The trolley comprises a driving device, a drive shaft, a frame and a track, wherein two wheels (1) are arranged at the upper part of the frame and suspended on the track (13), a rack (15) is arranged at the bottom of the track, a gear (7) meshed with the rack (15) is arranged in the middle of the frame, and the gear is fixed on the drive shaft (8) and is positioned by an elastic check ring (9); the drive shaft (8) is fixed on the frame through a bearing, and one end of the drive shaft (8) is connected with the driving device (10) which is fixed on a fixed block (11) on the frame through a screw bolt (12); and a speed reducer is connected with a motor to form the driving device (10). The utility model can be normally used under the condition of damp circumstance, particularly under the conditions of damp surface and low friction coefficient of the track; and the trolley is suitable for various worse working conditions, and can avoid the phenomenon of wheel skidding.
Description
Technical field
The utility model relates to the outstanding dolly technical field of electricity, relates in particular to the anti-skidding running trolley of a kind of electronic trolley crane.
Background technology
At present, the outstanding dolly of common electricity is to adopt actuating device direct drive adhesion wheel, friction by wheel and track drives the dolly ahead running, but this dolly only is adapted at using under the reasonable situation of operating mode, if under the environment of humidity, raceway surface makes its friction force reduce, the phenomenon that skidding appears in wheel because humidity reduces its friction coefficient equally.
Summary of the invention
For overcoming the deficiencies in the prior art, the utility model provides a kind of electronic trolley crane anti-skidding running trolley, is adapted at using the phenomenon of avoiding wheel to occur skidding under the relatively poor situation of operating mode.
For achieving the above object, the utility model adopts following technical scheme:
The anti-skidding running trolley of described electronic trolley crane, comprise: actuating device, transmission shaft, gear, tooth bar, vehicle frame, track, vehicle frame is made of frame plate, screw rod, and the middle part of two frame plates is provided with standing screw, and the bottom of two frame plates is provided with the screw rod that hangs weight; Each screw rod double headed roller silk passes axle sleeve and is fixed on the frame plate by nut.The top of vehicle frame is provided with two wheels, hangs in orbit, and the bottom of track is provided with tooth bar; The vehicle frame middle part is provided with and the tooth bar gears in mesh, and gear is fixed on the transmission shaft, and on vehicle frame, an end of transmission shaft connects actuating device to transmission shaft by bearing fixing, and actuating device is fixed on the fixed block of vehicle frame.
The anti-skidding running trolley of described electronic trolley crane, described gear is the drum type tooth.
The anti-skidding running trolley of described electronic trolley crane, actuating device are that reductor connects motor.
Owing to adopt aforesaid technical scheme, the utlity model has following preceence:
The anti-skidding running trolley of this electronic trolley crane, adopt on the transmission shaft with gear mesh with the tooth bar that the track bottom is provided with, be adapted at using under the relatively poor situation of various operating modes, even under the environment of raceway surface humidity, and also can normally use the phenomenon of avoiding wheel to occur skidding under the low situation of friction coefficient.
