Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific embodiments.

Referring to fig. 1 to 5, the present invention provides a technical solution of a spherical tank supporting device: the structure includes: spherical tank main part 1, a plurality of be the annular array equidistance connect in spherical tank main part 1 stand 2 all around still include a plurality of to be connected in adjacent two be used for supporting between the stand 2 the backup pad 3 of spherical tank main part 1 and a plurality of are in stand 2 and backup pad 3 between connecting rod 4, connecting rod 4 one end connect in backup pad 3 bottom, the other end is connected in stand 2's connecting rod 4, and the triangle-shaped structure is constituteed with stand 2, connecting rod 4 to backup pad 3 simultaneously, the effectual stability that improves the support, simultaneously through 3 effectual improvement of backup pad with spherical tank main part 1's area of contact, and then make spherical tank main part 1 atress distribute more evenly, further promote the stability of support.

3 left and right sides tops of backup pad are connected with two adjacent stands 2 adoption rotation through first pivot respectively, 4 one ends of connecting rod pass through the second pivot with 3 left and right sides bottoms of backup pad are rotated and are connected, and the other end passes through damper 5 and stand 2 swing joint, and then in the use, when spherical tank main part 1 received wind-force or filling production horizontal load, spherical tank main part 1 promoted corresponding backup pad 3 and slightly rotates on

stand

2, 3 bottoms of backup pad promotion connecting rod 4 of while reciprocate in stand 2, can effectively offset load, avoid equipment to damage, extension equipment life.

Damping mechanism 5 is including connecting in the shock attenuation connecting block 51 of connecting

rod

4, 2 inboards of stand have the confession the gliding stop rail 52 from top to bottom of shock attenuation connecting block 51, stop rail 52 has the gliding self-reset spring 53 of promotion shock attenuation connecting block 51, then when spherical tank main part 1 produces horizontal load, corresponding backup pad 3 uses first pivot to outwards swing on stand 2 as the center, and backup pad 3 promotes connecting rod 4 one end downswing, and the other end drives shock attenuation connecting block 51 and extrudes from self-reset spring 53 and along stop rail 52 downslide downwards simultaneously to offset spherical tank main part 1's load.

Backup pad 3 be with corresponding sector plate in spherical tank main part 1 lower hemisphere surface can improve the area of contact with spherical tank main part 1 on the one hand, and then makes spherical tank main part 1's stress distribution more even, and on the other hand is because backup pad 3 is corresponding with spherical tank main part 1 lower hemisphere surface, makes spherical tank main part 1 and backup pad 3 be connected more stably.
