Opening and closing device of horizontal compartment door

Abstract

The invention relates to an opening and closing device of a horizontal compartment door. In the technical scheme, a combined motion mechanism with a cart and a trolley is arranged above a compartment body, a compartment door is suspended on the trolley; a cart guide rail is arranged on a steel rail in the structure of the combined motion mechanism; an axial guide rail is arranged on the guide rail; the cart is arranged on the cart guide rail and is connected with a cart transmission system; the trolley is arranged on the axial guide rail and is connected with a trolley transmission system through a transmission screw; the compartment door is arranged in a free suspension state and is suspended on the hanging rod mechanism of the trolley; the cart moves along the cart guide rail to drive the trolley arranged on the cart and the suspended compartment door, thereby realizing the transverse movement of the compartment door; the trolley moves along the axial guide rail to drive the suspended compartment door, thereby realizing the axial movement of the compartment door; and when the compartment door and the compartment body are closed, a plurality of groups of automatic locking mechanism arranged on the outer side wall of the opening end of the compartment body can act to lock the compartment door and the compartment body. The invention realizes the convenient and non-destructive opening and closing of the compartment door of the large-scale vacuum apparatus, and has the advantages of reasonable structure and convenient operation; and the automatic locking mechanism has the advantages of reliable action and good sealing effect.

Description

technical field [0001] The invention belongs to the category of opening and closing operation of a hatch door, in particular to a hatch opening and closing device for a horizontal cabin of a large vacuum device. Background technique [0002] The vacuum hatch door in the prior art is conventionally hinged with loose leaves, and each opening and closing is under the condition of unbalanced force load, which is easy to cause one side of the loose leaf to support, there is no retreat, the closure is not good, and air leakage occurs; the other The side is prone to wear and tear of the sealing ring, resulting in air leakage. At the same time, for a large-scale vacuum chamber with a diameter of more than 2000mm, the weight of the door leaf is more than 1000kg, which is very easy to sag gradually during use, and the seal will fail until it is scrapped. Contents of the invention [0003] The purpose of the invention of the present application is to solve the above-mentioned def...
