A fixed-point self-locking mechanism

Abstract

The invention provides a fixed-point self-locking mechanism, which includes an outer cylinder flange, an outer cylinder, a locking oil cylinder, a universal locking block, and an inner cylinder; the outer cylinder flange and the end of the outer cylinder are connected and fixed, and the inner cylinder There is an inner cylinder; a locking cylinder is fixed on the outer cylinder, and a universal locking block is connected to the inner end of the locking cylinder. A trigger and a sensor are arranged on the locking cylinder, and the start and stop of the locking cylinder can be controlled by the trigger and induction. device control; the inner cylinder is provided with an annular slot whose shape matches the universal locking block. The invention adopts the locking method of the ring slot, which avoids the problem that the traditional bolt method is difficult to pull out due to long-term force, and uses a constant force opening meter to detect the in-position state of the load, which is easy to control and reliable.

Description

technical field [0001] The invention relates to a fixed-point self-locking mechanism. Background technique [0002] In many military engineering machinery, many large loads need to be erected to a certain angle for work, so it is necessary to lock the load after it is erected to the working angle, and the accuracy remains unchanged after locking. Because most of the loads are erected by hydraulic cylinders, it is difficult to achieve the maintenance accuracy of erecting in place only by hydraulic cylinders and hydraulic locks; if a mechanical latch structure is used, it will be difficult for the latch to be erected in place and placed for a long time. If it is pulled out, the pin will also be deformed due to long-term use, resulting in the pin not being able to be inserted. Due to the large working angle, it is difficult to realize by manual latching. Simultaneously, manual latch also reduces the degree of automation of the product. [0003] Several difficulties need to b...

Problems solved by technology

Since most of the loads are erected by hydraulic cylinders, it is difficult to achieve the maintenance accuracy of erecting in place only by hydraulic cylinders and hydraulic locks; if a mechanical latch structure is used, it will be difficult for the latch to be erected in place and placed for a long time. Pull out, the plug will be deformed due to long-term use, resulting in the plug can not be inserted

Due to the large working angle, it is difficult to achieve manual latching

At the same time, the manual latch also reduces the degree of automation of the product
