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 slot 1-26 of the key 1-4 faces the boss 1-24 and is inserted into the key hole 1-25, and rotates so that the convex teeth 1-16 face the convex The platform 1-24 can drive the lock core 1-15 to move away from the lock bar 1-12 to release the lock...

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 breechblock locking device for a coaxial push-pull type DF 37 millimeter antiaircraft gun. The locking device is fixed to a rocking frame housing of a gun, the locking device can enter the inner side of the rocker housing by stretching and retracting to block a moving locking rod of a protruding shaft, a locking core which is driven by a motor assembly is driven to slide abutting against a second spring, the locking rod penetrates through a first sleeve tube, restoring force is exerted on the locking rod by a first spring in the first sleeve tube, the locking core is used for blocking the restoring of the locking rod, and the locking rod is allowed to lock the breechblock. The invention further relates to a controlling method of the breechblock locking device for the coaxial push-pull type DF 37 millimeter antiaircraft gun. The device has the advantages that the structure is simple, the price is low, repairing and maintaining are convenient, and operator information recording can be achieved.

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 ...
