Problems solved by technology

With the development of the economy, the use of DF37mm anti-aircraft guns in China for artificial hail suppression and rainfall enhancement is increasing, and the equipment is widely distributed. The problem of safe use of DF37mm anti-aircraft guns has always existed, and it has become a prominent problem in the safe use of DF37 anti-aircraft guns in hail control operations.
Further restricting the use authority of the anti-aircraft gun breech is an important requirement for the safety management of anti-aircraft guns

Embodiment 2

[0037] On the basis of embodiment 1, in order to make the stepper motor 1-11 fault state or when the power supply for the stepper motor cannot be supplied, the locking of the protruding shaft 4 can be manually released after authorization, as Figure 4 , the top sectional view of the locking device 1, the locking device 1 is located on the side of the second section 1-62 and has a key hole 1-8, the key 1-4 passes through the key hole 1-8, and extends into the boss 1-24 close to the lock bar 1-12 sides, such as Figure 5 The end of the key 1-4 inserted into the locking device 1 has a semi-cylindrical slot 1-13, and the protruding teeth 1-14 are located on the side of the end away from the slot 1-13. When the lock cylinder 1-15 is in the When the locking lever 1-12 is blocked under the action of the reset part 2, the slot 1-13 of the key 1-4 faces the boss 1-24 and is inserted into the key hole 1-8, and rotates so that the convex teeth 1-14 face the convex The platform 1-24 can...

Embodiment 3

[0039] according to Figure 5 It can be seen that, based on the control method of the DF37 millimeter anti-aircraft gun directional machine locking device of embodiment 1 and embodiment 2, its steps are: after the DF37 millimeter anti-aircraft gun directional machine locking device control device is powered on, the fingerprint is verified on the fingerprint collection module by authorized personnel, After the verification is passed, press the unlock button, and the unlock button instructs the PLC controller to output a control signal to the motor driver according to the instruction, and the motor driver drives the motor to make the motor rotate, thereby realizing the unlocking of the gear ring of the steering gear.

[0040] Unlocking: after passing through the fingerprint verification of the operation panel 36, the input unlocking instruction is given to the PLC controller 37, and the PLC controller 37 outputs a control signal to the motor driver 39 according to the instruction...

Abstract

The invention discloses a DF37mm anti-aircraft gun breech locking device. The locking device is fixed on the cradle shell of the original cannon. The locking device has a locking rod that can stretch and enter into the inner side of the cradle shell to block the movement of a protruding shaft, and is driven by a motor assembly. The lock core is driven by the second reset part to slide against the lock rod, and the lock rod penetrates through the locking device and is applied with reset force by the reset part one. The lock core is used to block the reset of the lock rod, so that the lock rod locks the breech block. The invention also relates to a control method of the breech locking device of the DF37mm anti-aircraft gun. The device of the invention has simple structure, low price, is convenient for maintenance and repair, and can record information of operating personnel.

Description

technical field [0001] The invention belongs to a lock device, and more specifically relates to a DF37mm anti-aircraft gun breech locking device and a control method. Background technique [0002] 37mm anti-aircraft guns are the main tool for artificial hail prevention and rainfall enhancement in my country, with a large number and wide distribution. According to statistics in 2018, there are more than 7,000 anti-aircraft guns across the country, which are used for hail prevention and rainfall enhancement operations, and are an indispensable and powerful tool for disaster prevention and mitigation. This kind of anti-aircraft gun generally requires 4 to 6 manual operations. Since the anti-aircraft guns are mostly installed in the suburbs or on the top of mountains, there is currently no management device that restricts the use of DF37mm anti-aircraft guns. During the operation, the meteorological department designates multiple people to operate in the suburbs or on the top o...
