Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the obtained embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0026] As shown in Figure 2, the structure of the hydraulic composite launch device includes a target missile 1, a slewing support 2, a slewing machine 3, a launch platform 4, a base 5, and a crane fixture 6. The slewing machine 3 is fixedly installed on the base 5 through a slewing support device.

The hydraulic system provides power for the device, and the electrical control system provides control instructions for the launch device.

[0027] The internal structure of the rotary machine Figure 3 As shown in the figure, it adopts a profile welded frame structure, including a pitch angle rotary encoder installation position 31, a yaw angle rotary encoder 32, a slewing support 2 33, and a high and low oil cylinder lower support 34. The slewing machine is installed on the slewing outer ring of the slewing support 2 through connecting bolts, and the slewing machine is driven to rotate by the gear rotation of the hydraulic drive slewing support to realize the upper installation rotation. The slewing machine provides support for the launch platform, high and low oil cylinders, and slewing support installation. The launch platform angle is accurately monitored by installing yaw and pitch angle rotary encoders.

[0028] Base Figure 4 As shown in the figure, it adopts a profile welded frame structure, including a slewing support mounting seat 51, a pedal 52, a leg cylinder 53 and a base support frame 54. A slewing support mounting seat is set on the base and connected to the inner ring of the slewing support; a slewing limit device is set on the base to limit the left and right slewing angle of the slewing machine. The frame provides space and position for the installation of the slewing support, electrical system, hydraulic system, and crane fixture. The crane fixture is as shown in FIG. Figure 5 As shown, the locking tongue 61 and the rotating handle 62 are Figure 5 The state shown is the locked state of the driving fixture. When it is in the loose state, the corresponding hole of the launch platform can be moved through the lock tongue. Then, by rotating the handle 90°, the angle of the lock tongue is also adjusted 90°. At this time, the lock tongue limits the corresponding hole of the launch platform to complete the fixation of the launch platform. A tool box is set on the frame, which can be loaded with related spare parts and accessories. The base leg is installed with an outrigger cylinder, which is suitable for leveling the device in potholes. The outrigger cylinder has an adjustment range of 300mm, the outrigger bottom plate diameter is 0.398m, and the contact area with the ground is 0.12m 2 The bottom plate of the base legs is provided with transportation fixing holes, which are used to fix the launcher to the transport vehicle during transportation. Lifting rings are set on both sides of the base to meet the needs of lifting and getting on and off the vehicle. Pedals are laid on both sides of the launch platform above the base to facilitate the loading of target missiles.

[0029] The launch platform is a welded structure and is the base of the landing part. The launch platform body is mainly used to install the wing stopper 41 and the launch guide rail 42. Figure 6As shown. The guide rail is an inverted T-shaped structure, bolted to the launch platform. To adapt to the size of the projectile slider, the guide rail uses an inverted T-shaped groove guide rail, a total of 3, 6 meters long, installed on the upper plane of the launch platform through bolt assemblies, lined up in a row, and the spacing between adjacent guide rail brackets is 550mm, as shown Figure 7 shown.

[0030] The hydraulic system is the main system for executing the actions of the launch device. It is used to complete the lifting and leveling of the high and low cylinders, the rotation of the slewing support driving the slewing machine, and the lifting and leveling of the entire platform legs. The key hydraulic components of the hydraulic system are proportional speed control valves, multi-way reversing valves, solenoid ball valves and gear pumps, which can achieve stepless speed regulation, flow control, pressure regulation, energy saving and other requirements. The valve group can be controlled by the electronic control system or manually operated by the operator.

[0031] According to the functions of the components of the hydraulic system, the hydraulic system is composed of an oil pump motor group, a manual pump, a valve group, a hydraulic cylinder, a pipeline, and hydraulic accessories. The oil pump motor group, the manual pump, etc. provide hydraulic source for the hydraulic system to operate. Through the control operation of the valve group, the hydraulic oil is transmitted in the pipeline, so that each hydraulic cylinder performs the action as required and drives the movement of each actuator. According to the design input indicators and the functions and action requirements that each cylinder actuator needs to achieve, different hydraulic circuits are designed: 1) Hydraulic system oil source unit. The hydraulic system oil source and pressure regulating unit are mainly composed of an oil pump motor group (power unit), a manual pump, an oil tank, a filter, a pressure regulating valve group, etc. The system pressure regulation and protection of the system are achieved by adjusting the pressure to the specified pressure through the manual overflow valve. In addition, it is equipped with a hand pump, which can be used in an emergency to provide power source for the hydraulic system when the power supply cannot be operated; 2) The outrigger lifting hydraulic circuit, the outrigger lifting and leveling circuit is composed of a four-way multi-valve, a throttle valve, an electromagnetic ball valve, a hydraulically controlled one-way valve, a pressure sensor, and four outrigger cylinders. The single valve controls the single cylinder. The outrigger lifting and leveling are mainly operated by manual leveling, and the leveling is completed within 5 minutes; 3) The high and low lifting hydraulic circuit, the high and low lifting hydraulic circuit is mainly composed of an electromagnetic reversing valve, an electromagnetic ball valve, an explosion-proof valve, a pressure sensor, etc.; 4) Square The steering gear rotation hydraulic circuit is mainly composed of an electromagnetic reversing valve, a relief valve, an electromagnetic ball valve, a pressure sensor, etc., and the direction angle adjustment can be completed within 5 minutes; 5) Actuator hydraulic cylinder. In the hydraulic system, the outrigger circuit controls four outrigger cylinders, the height circuit controls one height cylinder, and the steering gear circuit controls a slewing support to achieve pressure regulation, extension, retraction of the outrigger cylinders and height cylinders and rotation of the slewing support, thereby completing the support leveling, height lifting, direction rotation and other functions of the launch platform through the hydraulic system.

[0032] The electrical system is the control component of the target missile launcher, which consists of a main control box, a battery box, a wired hand control box, a proximity switch, an encoder, connecting cables, etc. It realizes the operation mode selection, drives the hydraulic system to realize the rotation / height motion control, outrigger lifting / lowering control, rotation / height angle display, limit display, alarm display, USB output and other functions.

[0033] The electrical system uses an integrated display and control machine + mobile controller to control the erecting cylinder and slewing support, as well as the four leg cylinders. It also collects height and azimuth encoder data, hydraulic system pressure sensor data and filter signals, various position switch signals, etc. The height and azimuth encoder data are directly displayed on the screen after collection, and digital and analog output signals are used according to the settings of the control software to control the switching of the solenoid valve, the start and stop of the oil pump motor, and other actions, as well as alarms in the event of a fault.

[0034] The electrical system realizes the azimuth and height adjustment of the platform in automatic mode and semi-automatic mode. In automatic mode, by setting the rotation angle or height angle target value on the display screen of the main control box, it can automatically run to the target position after touching or pressing the button to confirm. In semi-automatic mode, the dual-axis joystick on the main control box or the dual-axis joystick on the wired hand control box is used to control the platform rotation or height movement. The operation information can be stored and output through USB; the lifting and lowering of the four legs are controlled separately by operating the hand control box.

[0035] The encoder and the main control box use CAN communication, and the main control box and the handheld operation box use RS485 remote communication.

[0036] The main control circuit adopts a highly reliable integrated display and control machine + mobile controller as the system control core, which has multiple analog acquisition inputs, multiple switch output interfaces, and multiple analog voltage output interfaces in one, greatly saving the volume and high reliability of the control system.

[0037] The invention has been verified by flight tests of target missile systems. The launch system works normally in low temperature, strong wind and sandy ground environments, and the target missile system can take off from the launch device according to a predetermined launch posture.

[0038] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present invention without departing from the spirit and scope of the embodiments of the present invention.
