Three-magnetic-wheel giant steel pipe crawling type work platform

Abstract

The invention discloses a three-magnetic-wheel giant steel pipe crawling type work platform. A left wheel support and a right wheel support are mounted on a triangular platform. A left hub and a right hub are mounted in the left wheel support and the right wheel support through drive shafts and bearings provided with bearing seats correspondingly, magnetic wheels are arranged on the two sides of the left hub and the two sides of the right hub correspondingly, and driving rubber wheels are fixed to the outer-diameter portion of the left hub and the outer-diameter portion of the right hub. One end of the left driving shaft is fixed into a speed reducer output hole provided with a left driving motor. One end of the right driving shaft is fixed into a speed reducer output hole provided with a right driving motor. Each steering wheel support is connected with a steering motor through a flange shaft sleeve, a steering shaft and a speed reducer. Steering hubs are mounted in the steering supports through driving shafts, magnetic wheels are arranged on the two sides of the steering hubs, and steering rubber wheels are fixed to the outer-diameter portions of the steering hubs. Steering driving motors are fixed to the right sides of the steering wheel supports through the speed reducers and connected with the driving shafts, and bearings are fixed to the left sides of the steering wheel supports and fixedly connected with the other ends of the driving shafts. A control unit provided with a cable is fixed to the triangular platform. The three-magnetic-wheel giant steel pipe crawling type work platform can be widely applied to various fields.

Description

Technical field: [0001] The invention relates to a working platform that can crawl on the inner and outer surfaces of giant steel pipes. Background technique: [0002] At present, there are basically two ways of operating platforms that can crawl on steel pipes using magnet adsorption: one is the magnet crawler method, and the other is the magnet plus four wheel method. No matter which method crawls on the inner and outer surfaces of the steel pipe It is very unstable during operation, and the swing is very large, which brings great difficulty to the precise operation on the surface. Whether it is a four-wheel walking or a crawler crawling operation platform, there is a phenomenon that one corner of the platform is suspended when the platform turns , so that the working equipment on the platform is difficult to control the quality of work. Therefore, there is an urgent need in this field for a kind of working platform that can crawl freely on the inner and outer surfaces of ...

[0002] At present, there are basically two ways of operating platforms that can crawl on steel pipes using magnet adsorption: one is the magnet crawler method, and the other is the magnet plus four wheel method. No matter which method crawls on the inner and outer surfaces of the steel pipe It is very unstable during operation, and the swing is very large, which brings great difficulty to the precise operation on the surface. Whether it is a four-wheel walking or a crawler crawling operation platform, there is a phenomenon that one corner of the platform is suspended when the platform turns , making it difficult for the working equipment on the platform to control the quality of the work. Therefore, there is an urgent need in this field for a working platform that can crawl freely on the inner and outer surfaces of giant steel pipes and is stable without swinging.
