Embodiment 1

[0031] according to figure 1 and figure 2 It can be seen that a DF37mm anti-aircraft gun direction locking device based on a worm sleeve includes a primary cannon 4 meshing with the direction gear ring 3, the bottom of the primary cannon 4 is fixedly connected to the cannon pan 2, and the direction machine locking device 1 includes a cannon that is fixedly connected to the cannon pan 2. The cover plate 11 and the steering gear locking device 1 are fixed below the cannon plate 2, and the space is narrow and small, which is unfavorable for manually implementing the destruction of the lock body.

[0032] Such as image 3 The steering lock device 1 includes a lock body 14 and a motor assembly. The lock body 14 is installed below the cover plate 11. The lock body 14 has a hollow portion, and the cover plate 11 is provided with a through hole connecting the hollow portion. The side of the main body 14 is connected with the motor assembly by special bolts. After the lock rod 28 pa...

Embodiment 2

[0038] On the basis of the device in embodiment 1, the outer circumference of the worm sleeve 19 and the inner circumference of the connecting sleeve 12 are all changed into cylindrical universal parts, such as figure 2 , but the circumferential surface of the connecting sleeve 12 is provided with a chute 33, the retaining ring bolt 24 passes through the chute 33, the worm sleeve 19 is connected to the retaining ring 17, and when the retaining ring bolt 24 also adopts a special bolt, the retaining ring 17 is easy to take out, and the worm Cover 19 is easier to process, and retaining ring bolt 24 can prevent worm screw cover 19 from rotating with worm screw 7 when worm screw 7 rotates. Simultaneously owing to being provided with retaining ring bolt 24, under special circumstances, as stepper motor 20 failures or under the situation of power supply interruption, the operator can open the back cover of stepper motor 20, while turning motor shaft 23 rear end rotors with wrench, di...

Embodiment 3

[0040] Both devices of embodiment 1 and embodiment 2 can be normally unlocked according to the following procedures. Such as Figure 6

[0041] When unlocking, after the operator passes the fingerprint verification PCL controller 37 to send an electric control command to the motor driver 39, the stepper motor 20 drives the worm rod 7 to rotate, so that the worm gear sleeve 19 moves backward, and the spring 2 18 is stretched backward under force. Make the lock cylinder 22 and the lock tongue 35 separate and unlock the lock lever 28, the lock lever 28 rises through the reaction force of the spring 1 27 and the lock tongue 35, and breaks away from the contact with the direction gear ring 3. The direction machine gear ring 3 is unlocked, and the direction gear ring Turn normally.

[0042] The principle of electric control is as follows:

[0043] according to Figure 6 It can be seen that a control method for a DF37mm anti-aircraft gun steering locking device comprises the foll...

Abstract

The invention discloses a DF 37 micrometer flack direction locking device based on a worm sleeve. A steering machine locking device is fixed on a flack disc of an original flack and is fixed to the position above a steering gear ring, a bolt of a lock bar of the steering machine locking device can mesh with or separate from the steering gear ring, a lock cylinder driven by a motor assembly penetrates through one side of a lock catch main body, a lock nut is mounted on the top of the lock bar, the lock bar penetrates through a cover plate and bears reset force exerted by a first spring in a concave cavity of the lock catch main body, and the lock cylinder is used for blocking resetting of the lock bar, so that the bolt of the lock bar meshes with the steering gear ring. The invention further relates to a control method of the flack direction locking device. The DF 37 micrometer flack direction locking device based on the worm sleeve is simple in structure, low in cost and convenient to maintain and repair, and operator information can be recorded.

Description

technical field [0001] The invention belongs to a lock device, more specifically relates to a DF37mm anti-aircraft gun steering gear locking device based on a worm sleeve, and also relates to a control method for the DF37 mm anti-aircraft gun steering gear locking device based on a worm sleeve. The DF37mm anti-aircraft gun is used for hail and rain enhancement. 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 anti-aircraft gun is manually operated and generally requires 4 to 6 people. Since anti-aircraft guns are mostly installed in suburbs or mountain tops, there is currently no manag...
