Quick opening and closing mechanism for horizontal type pressure container

Abstract

The invention discloses a quick opening and closing mechanism for a horizontal type pressure container, and belongs to the technical field of pressure containers. The horizontal type pressure container comprises a barrel body and a cover; the quick opening and closing mechanism comprises a first clamping hoop and a second clamping hoop which are semicircular, a first bidirectional screw, a second bidirectional screw and a cover pivoting supporting device, wherein a first locking seat is fixed at one end of the first clamping hoop, and a second locking seat is fixed at the other end of the first clamping hoop; a third locking seat is fixed at one end of the second clamping hoop, and a fourth locking seat is fixed at the other end of the second clamping hoop; the first locking seat is matched with the third locking seat, and the second locking seat is matched with the fourth locking seat; one end of the first bidirectional screw is connected to the first locking seat in a rotatable manner, and the other end of the first bidirectional screw is connected to the second locking seat in a rotatable manner; one end of the second bidirectional screw is connected to the third locking seat in a rotatable manner, and the other end of the second bidirectional screw is connected to the fourth locking seat in a rotatable manner; and the cover pivoting supporting device is arranged on the barrel body and pivoted with a cover. The invention has the advantages that: the quick opening and closing mechanism is prevented from being limited by the space, has high opening and closing speed, has a whole simplified structure, is favorable for manufacturing and mounting and convenient to use, and improves the safety by avoiding a phenomenon that the cover is opened mistakenly.

Description

technical field [0001] The invention belongs to the technical field of pressure vessels, and in particular relates to a quick opening and closing mechanism of a horizontal pressure vessel. Background technique [0002] The so-called quick opening and closing mechanism refers to the mechanism that quickly opens and closes the cover of the pressure vessel, which can be seen in patent documents, typically such as the "quick opening and closing mechanism for pressure vessels" recommended by the publication number CN1865736A, the patent application Proposed by the applicant on June 9, 2006. [0003] The above-mentioned patent application scheme objectively overcomes the shortcomings of CN1512090A (pressure vessel with quick-action opening and closing mechanism), and embodies the technical effect mentioned in paragraph 4 on page 4 of the specification. [0004] However, since the above-mentioned technical solution recommended by CN1865736A is for vertical pressure vessels, it is ...

AI Technical Summary

Problems solved by technology

[0004]However, since the above-mentioned technical solution recommended by CN1865736A is aimed at vertical pressure vessels, it is difficult or even impossible to transplant to horizontal pressure vessels. Specifically, if Applying the quick opening and closing mechanism suitable for vertical pressure vessels to horizontal pressure vessels will cause the following technical obstacles: First, it is limited by space, because no matter in the state of opening or closing the cover, the cover is used as the The connecting seat, screw and handwheel of the carrier will interfere with nearby objects; secondly, the opening and closing speed of the cover is slow, because whether the cover is opened or closed, the screw must be moved by the operation of the handwheel. Drive the connecting seat welded with the cover, and finally separate or cooperate the cover with the pressure vessel; third, the overall structure is complicated, which makes it troublesome to manufacture, install and use
