Abstract

The invention discloses a manhole with a horizontally supporting cover. The manhole comprises a manhole shell ring and a manhole cover (10), a support beam (7) is arranged on the manhole cover (10) and is 'L'-shaped, a horizontal arm of the support beam (7) is arranged below the manhole cover (10) and supports the manhole cover (10), a sleeve type supporting system is arranged on the outer wall of the manhole shell ring, a vertical arm of the support beam (7) is perpendicularly arranged on a side surface of the manhole via the sleeve type supporting system and can drive the manhole cover (10) to rotate in a horizontal plane around the vertical arm of the support beam (7). The manhole with the horizontally supporting cover has the advantages that the manhole cover can rotate horizontally, the manhole can be opened and closed conveniently, and work intensity and difficulty of operating or maintaining staff are reduced.

Description

technical field [0001] The invention relates to the field of petrochemical equipment, and more specifically relates to a manhole with a horizontal cover, which is suitable for large-scale equipment with a manhole at the bottom. Background technique [0002] In the equipment with bottom manhole, the spherical tank is a spherical storage container, which is composed of spherical shell, pillar, nozzle and other accessories, see figure 1 . Affected by the structural characteristics of the spherical tank, all process nozzles on the spherical tank are concentrated in the upper and lower poles, and the flange sealing surfaces of the nozzles are kept horizontal. In order to meet the requirements of internal maintenance, it is necessary to set a manhole at the center of the upper and lower pole belts of the spherical tank. Since the weight of the manhole cover of the spherical tank can reach more than 360Kg, the upper pole with the manhole needs to be equipped with a horizontal han...
