Single-shaft double-pin hinge type gate mechanism

Abstract

The invention discloses a single-shaft double-pin hinge type gate mechanism used for large and medium-size horizontal type containers. The single-shaft double-pin hinge type gate mechanism means that the opening and closing of a gate is realized through double rotating shafts, wherein the single shaft is a through shaft, and the gate can rotate 360 degrees around the through shaft; the double pins form the other rotating shaft and consists of an upper pin and a lower pin; the pin shafts are limited to rotate, and rotation limit angles are determined by the compression quantities of a regulation spring (26) and an adjustable bolt (27) on rotation limit mechanisms (17 and 18) so as to compensate a gap reserved because end faces of two flanges are not jointed when the gate is closed. The single-shaft double-pin hinge type gate mechanism is arranged at one side of the gate, a stress unit of the limited rotating shaft is a slide bearing structure, and a stress unit of a full rotating shaftis a rolling bearing structure. A gate flange (3) and a cabin flange (2) are tightly jointed through the cooperative micro rotation of the single shaft (13) and the double pin shafts (19, 20), and the gate flange (3) is better parallel to the cabin flange (2) through fine tuning around the double pin shafts (19 and 20). A plane steel frame consisting of front pin connecting rods (7, 8) and pin shaft connecting rods (9 and 10) and the gravity center of the gate are designed in the same plane so as to furthest reduce the misplaced displacement of the gate flange (3) vertical to the axial direction of a cabin (1).

Description

【Technical field】 [0001] The invention relates to a single-axis double-pin hinged gate mechanism, which belongs to the field of gate mechanisms for large and medium-sized horizontal containers. 【Background technique】 [0002] The door mechanism of large and medium-sized horizontal containers is the main or even the only way to enter and exit the container. The maintenance of high pressure or high vacuum in the container is greatly affected by the sealing performance of the door. After the door is closed, if the door flange and the cabin flange cannot be well connected If it does not fit properly, an effective seal of the container at the door cannot be guaranteed. The weight of the gate of large and medium-sized horizontal containers with a diameter greater than 4m is several tons or even more than ten tons. The effective load-bearing of this type of heavy-duty gate is a factor that must be considered when designing the gate. [0003] The gate mechanism of large and medium-...

AI Technical Summary

Problems solved by technology

[0003] The gate mechanism of large and medium-sized horizontal containers mostly adopts the translational or hanging type, and seldom adopts the hinged type. The end faces of the cabin flanges do not fit together and the end faces of the two flanges are misaligned. In addition, because the hinges are usually installed on one side of the door, the force-bearing structure is asymmetrical. During the production, assembly and long-term operation of the door, The deformation of the hinge mechanism caused by the self-weight of the door will aggravate the degree of "lax closing"
