Description

Technical Field

[0001] The present invention relates to the technical field of anti-overturning swing legs of radar vehicles, and particularly relates to an anti-overturning swing leg structure and a control method for a radar vehicle with one-key linkage deployment and retraction. Background Art

[0002] With the rapid development of the stable support technology for vehicle-mounted equipment, the requirements for the rapid deployment and retraction efficiency of movable platforms are increasing day by day. Traditional vehicle-mounted stable support devices generally have problems such as low deployment and retraction efficiency and insufficient operation coordination. Most of the common hydraulic support structures in the prior art adopt an independent drive mode, and each leg needs to be adjusted one by one, which is not only time-consuming and laborious, but also difficult to achieve synchronous actions of multiple mechanisms. More prominently, conventional devices generally rely on manual judgment of the support state and lack an integrated automatic leveling mechanism, and are prone to unstable support under complex terrain conditions, seriously affecting the operation safety and deployment timeliness of the equipment.

[0003] Although the hydraulic support systems disclosed in existing patents have an electric drive function, their transmission mechanisms still adopt a split design, resulting in timing errors in the deployment and retraction actions and making it difficult to ensure the coordinated movement of multiple legs. Another folding support frame proposed in the prior art has improved the storage space, but manual intervention is still required for positioning and locking during the deployment and retraction process, and the operation process is cumbersome. These technical defects seriously restrict the application effect of vehicle-mounted equipment in scenarios with strict timeliness requirements such as emergency rescue and engineering inspection.

[0004] These problems directly lead to the difficulty of traditional devices in meeting the core requirements of modern mobile devices for rapid response and precise leveling, and also hinder the improvement of the automation operation level. Therefore, it is urgent to develop a new type of stable support system with integrated drive and intelligent control characteristics to break through the limitations of the prior art. Summary of the Invention

A sealing ring 15 is also provided on the inner side of the bearing 14 axially and is installed between the rotating shaft 12 and the chassis of the radar vehicle.

[0054] The swing leg leveling leg 2 in the present invention is composed of a leveling leg 21, a leveling leg mounting seat 22, and a protective cover 23; the leveling leg 21 is a telescopic structure, which is hinged to the end of the anti-overturning swing leg 1 through the leveling leg mounting seat 22, and a protective cover 23 is provided outside. Among them, a pressure sensor is provided on the leveling leg 21, and the leveling process includes the pressure sensor detecting the ground contact pressure and automatically adjusting the telescopic length of the leveling leg 21 through the servo system.

[0055] The swing leg retracting and locking mechanism 3 in the present invention is composed of a locking support frame 31, a locking pin 32, a locking positioning seat 33, and a locking anti - detachment pin 34; the locking support frame 31 is fixedly arranged at the corresponding retracting position of the anti - overturning swing leg 1 on the radar vehicle chassis; the locking pin 32 is slidably matched with the locking support frame 31, and the locking anti - detachment pin 34 penetrates through the end of the pin.

[0056] The swing leg unfolding and retracting support assembly 4 in the present invention is composed of a connecting rod mounting seat one 41, a connecting rod one 42, a connecting rod two 43, and a connecting rod mounting seat two 44; the connecting rod one 42 and the connecting rod two 43 are hinged end to end to form a connecting rod mechanism, and then connected to the connecting rod mounting seat one 41 and the connecting rod mounting seat two 44 to form a foldable four - connecting - rod structure.

[0057] The swing leg unfolding and locking mechanism 5 in the present invention is composed of a pull rod mounting seat one 51, a pull rod 52, and a pull rod mounting seat two 53; the pull rod 52 is a rigid rod with adjustable length, and both ends are connected between the anti - overturning swing leg 1 and the radar vehicle chassis through the pull rod mounting seat one 51 and the pull rod mounting seat two 53.

[0058] The control assembly 6 in the present invention is composed of an oil cylinder mounting seat one 61, a telescopic oil cylinder 62, and an oil cylinder mounting seat two 63; the telescopic oil cylinder 62 is a double - acting hydraulic cylinder, and the end of its piston rod forms a force - transmission cooperation with the connecting rod mechanism of the swing leg unfolding and retracting support assembly 4.

[0059] The working principle and working process of the anti - overturning swing leg structure and control method of the one - key linkage unfolding and retracting radar vehicle in the present invention are briefly described below.

[0060] When the control assembly 6 is operated to unfold, the telescopic oil cylinder 62 of the control assembly 6 extends, conducts the force to the swing leg unfolding and retracting support assembly 4, and the swing leg unfolding and retracting support assembly 4 moves from the retracted state to the unfolded state. The swing leg unfolding and retracting support assembly 4 conducts the force to the anti - overturning swing leg 1, and the anti - overturning swing leg 1 moves from the retracted state to the unfolded state. After unfolding in place, the swing leg unfolding and locking mechanism 5 forms a locking through the center of the anti - overturning swing leg 1 through the axial tension of the pull rod 52, and locks the anti - overturning swing leg 1. The swing leg leveling leg 2 installed at the end of the anti - overturning swing leg 1 extends and automatically levels after touching the ground.

[0061] When the operation control component 6 is retracted, the swing leg unfolding and locking mechanism 5 and the anti-overturning swing leg 1 are unlocked from the locked state. The leveling leg 2 of the swing leg installed at the end of the anti-overturning swing leg 1 is retracted. After the retraction is in place, the telescopic oil cylinder 62 of the control component 6 is retracted from the telescopic state, and the force is transmitted to the swing leg unfolding and retracting support component 4. The swing leg unfolding and retracting support component 4 moves from the unfolded state to the retracted state. The swing leg unfolding and retracting support component 4 transmits the force to the anti-overturning swing leg 1. After the anti-overturning swing leg 1 moves from the unfolded state to the retracted state, the swing leg retracting and locking mechanism 3 locks the retracted anti-overturning swing leg 1.
