Embodiment 2

[0038] On the basis of embodiment 1, in order to overcome the stepper motor 1-11 when unable to obtain power supply or failure, it can still be unlocked, as Figure 6 , set the key hole 1-25 at the corresponding position on the circumferential surface of the sleeve two 1-13 and the worm sleeve 1-22, such as image 3 After key 1-4 is inserted into keyhole 1-25, stretches into protruding ring 1-24 near the side of lock bar 1-12, as Figure 7 The end of the key 1-4 inserted into the locking device 1 has a semi-cylindrical slot 1-26, and the protruding teeth 1-16 are located on the side of the end away from the slot 1-26. 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 missing groove 1-26 of the key 1-4 faces the convex ring 1-24 and is inserted into the key hole 1-25, and then rotates so that the convex tooth 1-16 faces the convex tooth. The ring 1-24 can drive the lock core 1-15 to move away from the lock ba...

Embodiment 3

[0042] according to Figure 8 It can be seen that, based on the control method of the coaxial push-pull type DF37 millimeter anti-aircraft gun steering locking device of embodiment 1 and embodiment 2, the steps are: after the DF37 millimeter anti-aircraft gun steering locking device control device is powered on, the fingerprint collection module is activated by authorized personnel. Verify the fingerprint on the screen. After the verification is passed, press the unlock button. The unlock button will give the PLC controller an output control signal to the motor driver according to the command. The motor driver will drive the motor to make the motor rotate, thereby unlocking the gear ring of the steering gear.

[0043] Unlocking: after passing through the fingerprint verification of the operation panel 36, the input unlocking command is given to the PLC controller 37, and the PLC controller 37 outputs a control signal to the motor driver 39 according to the command, and the moto...

Abstract

The invention discloses a coaxial push-pull type DF37mm anti-aircraft gun breech locking device. The locking device is fixed on the cradle shell of the original cannon. The lock cylinder driven by the motor assembly is driven by the second spring to slide against the lock lever. The lock lever penetrates through the sleeve one, and the reset force is applied by the spring one in the sleeve one. The lock cylinder is used to block the reset of the lock lever, so that the lock lever locks the breech . The invention also relates to a control method of the coaxial push-pull type DF37mm anti-aircraft gun breech locking device. 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 coaxial push-pull type 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 ...
