Abstract

The invention discloses a work platform device in a spherical tank and a movement method and belongs to the technical field of building of work platforms in spherical tanks. The work platform device comprises a transmission assembly, pull rod assemblies, an upper end fixed assembly, a lower end fixed assembly and operation platforms. The upper end of the transmission assembly and the upper end fixed assembly are axially and fixedly connected. The lower end of the transmission assembly and the lower end fixed assembly are axially and fixedly connected. The pull rod assemblies and the lower endfixed assembly are connected through a hinge, meanwhile the pull rod assemblies are connected with the transmission assembly through threads, and the operation platforms are connected to the tail endsof the pull rod assemblies through hinges. Two or more sets of pull rod assemblies and the operation platforms are installed around the transmission assembly, are evenly distributed in the peripheraldirection and can rotate up and down simultaneously around the lower end fixed assembly. The work platform device can replace a scaffold, installation is fast and convenient, no work dead zone exists, the operation platforms can carry work tools, the platform movement can be controlled, and thus work space needed by tank work is achieved.

Description

technical field [0001] The invention relates to a device and a movement method for an internal operation platform of a spherical tank, belonging to the technical field of erecting an internal operation platform of a spherical tank. technical background [0002] At present, manual work on the tank body inside the large spherical tank, such as cleaning, grinding, inspection, coating, etc. of the tank body, requires scaffolding to complete the manual work. The installation period of the scaffold is long, and the scaffold must be built on the inner wall of the tank, so there are problems such as limited operating space, dead space in the working space, and difficulty in carrying tools. It is necessary to develop a working platform device that can replace the scaffolding, which is fast and convenient to install, the operator can work on the working platform, and can control the movement of the working platform device so that it can reach any required working space on the inner su...
