Embodiment Construction

[0018] Below in conjunction with accompanying drawing, the present invention is described in detail:

[0019] An auxiliary equipment for manned inspection inside a spherical tank, characterized in that it consists of a hanger 1, a vertical support column 7, a horizontal support rod 10 and a manned work basket 11;

[0020] The hanger 1 is an umbrella frame hinged metal structure that can be expanded and retracted. The handle of the umbrella frame is a hollow steel pipe structure. On the upper manhole flange 3 of the upper mouth, when the umbrella skeleton is opened, the multiple supporting ends of the hinged metal structure are evenly distributed along the inner wall around the upper mouth of the spherical tank, and each supporting end point is fixedly installed with a spring contact; the umbrella skeleton is hinged The metal structure is fixed on the inner wall of the spherical tank through the spring contact at the supporting end;

[0021] At the bottom of the central axis o...

Abstract

The invention discloses an auxiliary man-riding appliance for regular checkups in a spherical tank and relates to a man-riding device for regular checkups in a spherical tank. The auxiliary man-riding appliance for regular checkups in the spherical tank comprises a hanging bracket (1), a vertical supporting stand column (7), horizontal supporting rods (10) and a man-riding working basket (11). The hanging bracket (1) is of an umbrella framework type hinged metal structure and fixed to an upper opening of the spherical tank, the vertical supporting stand column (7) is fixed to a center shaft at the lower end of the hanging bracket (1), and three thrust bearings are fixed to the upper portion and the lower portion of the vertical supporting stand column (7) respectively. The two thrust bearings on the lower portion of the vertical supporting stand column (7) are located away from the center point of the spherical tank for the distance equal to the height of the thrust bearings. One ends of the four horizontal supporting rods (10) are hinged to four pins of the outer rings of the thrust bearings on the lower portion respectively, and the other ends of the four horizontal supporting rods (10) are hinged to the man-riding working basket (11). A manual winch (13) is fixed to the man-riding working basket (11). A lower pulley block (15) is fixed to each horizontal supporting rod (10). Upper pulley blocks (14) are fixed to the uppermost thrust bearing. The auxiliary man-riding appliance for regular checkups in the spherical tank is simple in structure, easy to detach and install, and high in safety performance and working efficiency.

Description

technical field [0001] The invention belongs to the field of special inspection equipment for industry, in particular to a fixed inspection and manned equipment inside a spherical tank. Background technique [0002] With the development of the chemical industry, various pressure-bearing spherical liquid storage tanks are widely used. After the pressure-bearing spherical liquid storage tank has been used for a certain number of years, it is necessary to conduct regular inspections on the welds inside the spherical tank. In order to enable the inspectors to reach each weld in the spherical tank, it is generally necessary to set up temporary scaffolding inside the spherical tank. For inspectors to climb. The disadvantages of this approach are: [0003] (1) The construction workload is heavy and the cycle is long. Due to the large internal volume of the spherical tank, thousands of rack rods, rack plates, and fasteners are required to build the shelf. After transporting to th...
