Description

Technical Field

[0001] The present invention relates to the technical field of ammunition box launching systems, and in particular to a control system for box cable plugging and box locking, and a box. Background Art

[0002] Missile box launch, also known as "storage box launch" or "shipping box launch", is a missile launched from a box-shaped container fixed to the launch rack.

[0003] The box-type container has three functions: (1) as a transport box. The missile is placed on the guide rails inside the box, and the buffer and positioning locking devices are used to prevent the missile from being damaged by impact and vibration during transportation; (2) as a storage box. The box has a temperature control device and is filled with nitrogen and dry air. After being sealed, the storage period can be extended; (3) as a launch box. The box has a launch rail, a safety locking mechanism and a cable, and is connected to the launch control system to implement pre-launch inspection, aiming and launch. This launch method is often used for cluster launches of multiple missiles from ship-to-ship (submarine), ship-to-air and surface-to-air missiles.

[0004] In the Chinese patent document with publication number CN118004010A, a self-loading and unloading vehicle for storing and transporting ammunition boxes is disclosed. The self-loading and unloading vehicle for storing and transporting ammunition boxes includes a chassis assembly, an erection frame and a sliding frame. One end of the erection frame is hinged to the rear of the chassis assembly. A first telescopic driving member is hinged on the chassis assembly. The telescopic end of the first telescopic driving member is hinged to the erection frame. The first telescopic driving member can drive the erection frame to rotate relative to the chassis assembly. The sliding frame is slidably installed on the erection frame, and the first telescopic driving member is hinged to the erection frame. A second telescopic driving member is installed on the erecting frame, and the telescopic end of the second telescopic driving member is connected to the sliding frame. The second telescopic driving member can drive the sliding frame to slide relative to the erecting frame. A third telescopic driving member and a conveying mechanism are installed on the sliding frame. The third telescopic driving member can pull the bracket on which the storage and transport box is fixed to the sliding frame. The conveying mechanism can convey the bracket located on the sliding frame. A fixing mechanism is installed on the sliding frame, and the fixing mechanism is used to fix the bracket on the sliding frame.

[0005] Before the ammunition box is launched, the box body needs to be locked and fixed, and the launch control cable needs to be plugged in. The traditional box locking and cable plugging are two systems. The traditional locking box system uses an electric method, the mechanism is prone to jamming, and the motor is prone to overload. Summary of the Invention

[0006] In view of the defects in the prior art, the purpose of the present invention is to provide a control system for cable plugging and locking of a box and a box.

[0007] According to the present invention, a control system for box cable plugging and box locking is provided, comprising: a plugging electro-hydraulic servo unit, a lock box electro-hydraulic servo unit and a plugging lock box controller;

[0008] The plug-in electro-hydraulic servo unit is electrically connected to the plug-in phase lock controller, and the lock box electro-hydraulic servo unit is electrically connected to the plug-in lock box controller;

[0009] The plug-in electro-hydraulic servo unit includes a plug-in hydraulic cylinder for plugging in the box cable, and the locking box electro-hydraulic servo unit includes a locking box hydraulic cylinder for locking the box.

[0013] The DC servo motor rotates to drive the gear pump in the oil tank to work, and controls the movement of the plug-in hydraulic cylinder or the lock box hydraulic cylinder through the oil circuit in the valve block.

[0014] Preferably, the DC servo motor and the gear pump are connected via a coupling.

[0015] Preferably, an air bag is provided in the oil tank, and the air pressure balance in the cylinder is controlled by the air bag.

[0016] Preferably, the valve block is provided with an overflow valve, and when the motor pressure is overloaded, the pressure is released through the overflow valve.

[0017] Preferably, the plug-in lock box controller is provided with a control circuit board and a motor driver, and a V power supply interface is provided on the control circuit board, through which power is respectively supplied to the plug-in electro-hydraulic servo unit and the lock box electro-hydraulic servo unit; the control circuit board includes a CAN communication interface, which receives instructions issued by the upper computer through the CAN communication interface, and controls the motor driver according to the instructions, thereby controlling the rotation of the DC servo motor.

[0019] A box provided according to the present invention includes the control system for box cable plugging and box locking.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. Traditional box locking and cable plugging are two systems. This system integrates them into an integrated design. The program automatically controls the locking of the ammunition box and the plugging of cables, which is convenient for personnel operation.

[0022] 2. This system adopts automatic and manual working modes, and has a manual pump interface to facilitate the system to work quickly in the event of a power outage.

[0023] 3. Traditional lock box systems use electric methods, which can easily cause the mechanism to jam and the motor to overload. This system uses an electro-hydraulic system, which will not jam. When the load is too large, the overflow valve opens to prevent the motor from overloading.

[0024] 4. Traditional plug-in systems use hydraulic or pneumatic systems with complex piping structures and are prone to oil and air leaks. This system uses a pump-controlled cylinder electro-hydraulic servo system, which is compact, highly integrated, has no external piping, and is leak-proof. Furthermore, the system can precisely control the maximum load of the system through a relief valve to prevent damage to cable connectors. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] DETAILED DESCRIPTION

[0034] The present invention will be described in detail below with reference to specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those skilled in the art, several changes and improvements can be made without departing from the scope of the present invention. These all fall within the scope of protection of the present invention.

[0035] The present invention discloses a control system for box cable plugging and box locking, including a plug-in electro-hydraulic servo unit 3, a lock box electro-hydraulic servo unit 4 and a plug-in lock box controller; the plug-in electro-hydraulic servo unit 3 is electrically connected to the plug-in phase lock controller, and the lock box electro-hydraulic servo unit 4 is electrically connected to the plug-in lock box controller.

[0036] In a preferred embodiment, the plug-in electro-hydraulic servo unit 3 and the lock box electro-hydraulic servo unit 4 are each provided with two groups, referring to Figure 1 As shown, it includes left and right plug-in electro-hydraulic servo units 3, and left and right lock box electro-hydraulic servo units 4.

[0037] The plug-in lock box controller is electrically connected to the plug-in electro-hydraulic servo unit 3 through the signal cable 1 and the control cable 2. Similarly, the plug-in phase lock controller is electrically connected to the lock box electro-hydraulic servo unit 4 through the signal cable 1 and the control cable 2.

[0038] The plug-in electro-hydraulic servo unit 3 includes a DC servo motor 8, a valve block 10, a fuel tank 12, and a plug-in hydraulic cylinder 18. The DC servo motor 8 rotates, driving the gear pump 16 in the fuel tank 12. This in turn controls the movement of the plug-in hydraulic cylinder 18 through the oil circuit in the valve block 10. The DC servo motor 8 and the gear pump 16 are connected via a coupling 15. An air bladder 17 is incorporated into the fuel tank 12 to balance the pressure within the cylinder and reduce the pressure within the tank 12. When the lock-box hydraulic cylinder 13 is extended, the hydraulic oil flowing into the tank 12 is less than the hydraulic oil flowing out of the tank 12, causing the pressure within the tank 12 to be significantly lower than the external pressure. The expansion of the air bladder 17 offsets this pressure difference. Similarly, when the lock-box hydraulic cylinder 13 is retracted, the hydraulic oil flowing into the tank 12 is greater than the hydraulic oil flowing out of the tank 12, causing the pressure within the tank 12 to be significantly higher than the external pressure. The contraction of the air bladder 17 offsets this pressure difference. The oil tank 12 is also equipped with an exhaust port 11. The mounting interface of the bladder 17 is installed at this port, allowing the interior of the bladder to communicate with the outside air, allowing air to be drawn in or out as the bladder expands or contracts. When the hydraulic cylinder reaches its extreme ends or is subjected to a load exceeding its limit, the relief valve 9 on the valve block 10 activates to protect the system from motor overload. Furthermore, the system includes a manual pump connector 14, allowing an external manual pump to be connected to manually control the system in the event of a power outage. The plug-in lockbox controller also includes a debugging port 7, allowing internal program updates to adapt to different usage scenarios.

[0039] The lockbox electro-hydraulic servo unit 4 includes a DC servo motor 8, a valve block 10, an oil tank 12, and a lockbox hydraulic cylinder 13. The connection method of the DC servo motor 8, valve block 10, oil tank, and lockbox hydraulic cylinder 13 is the same as that of the plug-in electro-hydraulic servo unit 3 and will not be repeated here. The lockbox hydraulic cylinder 13 is an asymmetric cylinder.

[0040] The control circuit board 20 includes an MCU, a CAN transceiver module, a FLASH module, a motor communication module, and a motor control module. When the system is powered on, the MCU reads internal configuration data through the FLASH module, receives configuration and control instructions through the CAN transceiver module, and saves the configuration data to the FLASH module through data processing, or executes motor control through the motor control module. After powering on, the MCU performs a real-time self-check of its own status, simultaneously inquiring about the motor status through the motor communication module in real time, and uploading motor status feedback and self-check information via the CAN transceiver module.

[0041] The plug-in lock box controller is equipped with a control circuit board 20 and a motor driver 19. A 24V power supply interface 5 is provided on the control circuit board 20, which supplies power to the plug-in electro-hydraulic servo unit 3 and the lock box electro-hydraulic servo unit 4. The CAN transceiver module includes a CAN communication interface 6, which receives instructions from the host computer and controls the motor driver 19 according to the instructions, thereby controlling the rotation of the DC servo motor 8.
