Abstract  With the development of science and technology, pressure vessels using quick actuating device is becoming more and more common. How to make the quick door-opentype pressure vessels automatically lock safely and reliably after being closed and compacted, it is always a difficult technical problem. This article presented a new type of quick door-opentype pressure vessels safety locking device consisting of the hook, rod, stick, frame and lock cylinder,in which the hook, rod, stick and frame formed a four-bar linkage. When the vessel's gate quickly closed and compacted, it was closely locked at the “dead spot” of the rod and stick and the “dead spots” position was locked by the clamping cylinder. The device achieved its locking status by its own energy when pressed. The compression hook and clamping block could not only be pressed closely, but also locked closely.Therefore, not merely is the device stable and reliable, but its structure is simple and its operation is convenient as well．

Key words： pressure vessel      quick door-opentype      safety lock      four-bar linkage      “dead spots”position

压力容器快开门安全锁紧装置的设计

压力容器上使用快开门装置越来越普遍,如何使压力容器快开门关闭和压紧后,能自动锁紧且安全可靠,一直是一项技术难题.提出一种新的纯机械控制压力容器快开门安全锁紧装置,由压紧钩、连杆、摇杆、机架及锁紧气缸组成,其中压紧钩、连杆、摇杆和机架构成了四杆机构.在容器门盖快速关闭和压紧后,利用四杆机构中的连杆和摇杆“死点”位置来锁紧,“死点”位置再由锁紧气缸锁定.该装置是借助压紧时本身的能源来实现锁紧的,压紧钩与压紧块既可压紧又能锁紧,不仅结构简单、操作方便,而且锁紧性能稳定、可靠.
