Abstract
The invention discloses a universal joint compensation support. The universal joint compensation support comprises spherical joint compensators, a length regulator and connection plates. The length regulator is provided with a seamless steel tube shaft and connected with the spherical joint compensators through the seamless steel tube shaft. The connection plates are located at the ends of the universal joint compensation support and located at the outer sides of the spherical joint compensators correspondingly. Due to the fact that the spherical joint compensators with spherical joints are adopted, angular displacement in any directions within a given angle is achieved. The length regulator is used for increasing or decreasing the length of the universal joint compensation support and regulating the universal joint compensation support to an appropriate length. The connection plates have the main function of fastening together the universal joint compensation support and connection elements on equipment and connection elements on a pipeline. The seamless steel tube shaft is used for bearing axial loads of the universal joint compensation support. Through the adoption of the structural design, the axial loads are centralized on the seamless steel tube shaft of the length regulator, the bearing load of the universal joint compensation support is increased, and the universal joint compensation support can adapt to vertical displacement differences.
Description
Technical field
The present invention relates to pipelines and petrochemical pipelines device technique field, particularly relating to can at the arbitrarily angled universal joint compensation support compensating pipeline angular displacement by set angle.
Background technique
Along with technological progress, the production capacity of petrochemical equipment significantly improves, and the diameter of the import and export pipeline that the diameter of reaction vessel (tower), height and attachment reaction container (tower) lay also significantly increases, and thereby produces three problems:
1, the import and export pipe diameter that the diameter of reaction vessel (tower), height and attachment reaction container (tower) lay significantly increases, cause reaction vessel (tower) to import and export pipeline wind load to increase, the stability of the pipeline that attachment reaction container (tower) lays reduces, and easily generation is rocked, vibrated;
2, four kinds of thermal conditions are usually had between reaction vessel (tower) and import and export pipeline, the i.e. cold Guan Leng of tower, tower heat pipe heat, the cold pipe heat of tower heat pipe cold, tower, wherein latter two operating mode can produce larger vertical displacement and angular displacement between reaction vessel (tower) and import and export pipeline, and along with the increase of reaction vessel (tower), this displacement difference is also increasing;
3, pipeline attachment reaction container (tower) lays, and support of pipelines is taken root on reaction vessel (tower), and traditional support of pipelines can only compensate the displacement of a direction, cannot meet the compensation requirement of vertical displacement and angular displacement.
In Chinese patent literature CN104565161A, disclose a kind of elastic compensating device, this elastic compensating device comprises pressing plate and resilient cushioning element, also comprises: shell and several bolts of adjusting; Described shell upper-end surface is evenly arranged consistent with described bolt quantity of adjusting, and the tapped through hole that screw thread is suitable, be fastened with the bolt of adjusting preloading position for locking described pressing plate in described tapped through hole; The elastic reaction upper-end surface of described resilient cushioning element contacts with described pressing plate lower end surface.Further, described resilient cushioning element is single spring, the spring of multiple coaxial line nested arrangement, pneumatic spring or hydraulic cushion parts.In the technological scheme of this patent documentation, although the equipment under the effect of temperature and pressure that solves can expand or the change in shape such as contraction and cause this kind equipment to produce the problem of additional active force in bearing, still desirable requirement is not reached for above-mentioned three problems faced.
Therefore, be necessary to work out a kind of new support of pipelines, make it can compensate pipeline angular displacement arbitrarily angled by set angle, it can adapt to pipeline and equipment due to the different vertical displacement that causes of expanding with heat and contract with cold poor, support and stabilization are played to the pipeline near equipment, is specially adapted to conveying thermal medium and takes root in the pipeline of equipment.
