Crane encoder mounting structure

Abstract

The invention discloses a crane encoder mounting structure which comprises a wheel axle and a crane wheel and further comprises a U-shaped mounting frame, wherein the wheel axle is fixedly sleeved with the crane wheel; two ends of the wheel axle are fixedly sleeved with first bearings; each first bearing is mounted in one corresponding bearing housing; the U-shaped mounting frame is oppositely fixed with the bearing housing; a rotating shaft is arranged between two side plates of the mounting frame in a penetrating manner, and is fixedly sleeved with a friction wheel; the friction wheel is coaxial with the rotating shaft; the circumferential side wall of the friction wheel is in contact and matched with that of the crane wheel; an encoder is fixedly connected with one end of the rotating shaft; an input shaft of the encoder is coaxially arranged with the rotating shaft. Through adoption of the crane encoder mounting structure, no mounting hole needs to be formed in the wheel axle and the friction wheel is in direct contact with the crane wheel, so that the accuracy of data acquisition is remarkably improved; besides, the encoder is convenient to mount and operate, and particularly under the circumstance that no mounting hole is formed in a delivered wheel axle, additional arrangement of the encoder can be convenient. Therefore, the crane encoder mounting structure has the characteristics of ingenious concept, simple structure, easiness in transformation and the like.

Description

technical field [0001] The invention belongs to the technical field of cranes, and in particular relates to a crane encoder installation structure. Background technique [0002] At present, during the operation of the crane, the lifting items need to be transported smoothly, reliably and safely; in particular, the speed of large and small vehicles needs to be even after lifting the goods. During the operation of the crane, the speed of the large and small vehicles is consistent with the linear speed of the wheels. Therefore, encoders are installed on the large and small wheels of the crane to monitor the rotation speed of the wheels. [0003] Existing crane wheel encoders are mainly directly fixedly connected to the wheel shaft through a coupling, which requires coaxial mounting holes on the wheel shaft, so that the installation structure of the encoder takes up a large space, and the installation operation is complicated. The coaxial precision between the hole and the whe...

Problems solved by technology

[0003] Existing crane wheel encoders are mainly directly fixedly connected to the wheel shaft through a coupling, which requires coaxial mounting holes on the wheel shaft, so that the installation structure of the encoder takes up a large space, and the installation operation is complicated. The coaxial precision between the hole and the wheel axle is required to be high. Once the accuracy error is large, the data collected by the encoder will easily be inaccurate; and once the wheel slips on the wheel axle, the linear velocity data of the wheel cannot be accurately collected.

Furthermore, for cranes that are not equipped with encoders when leaving the factory, since there are no installation holes on the wheel shafts, it is almost impossible to open installation holes that meet the coaxial precision requirements, and it is very difficult to add encoders
