Description

Technical Field

[0001] The invention relates to an electrical control system for storage and transportation integrated equipment. Background Art

[0002] In the process of marketization of the aerospace industry, it is extremely important to use launch pads and launch platforms to launch carrier rockets. The launch cost, stability and safety of carrier rockets are important advantages that help companies stand out in the competition of commercial aerospace. Therefore, an electrical control system for storage and transportation equipment that is flexible in control, stable in operation, highly reliable and easy to maintain is of great significance. For example, a manual hydraulic integrated top loading vehicle disclosed in CN114249267A has a multi-degree-of-freedom adjustment platform on the platform, and the handling and launch posture adjustment of equipment such as rockets are achieved through the lateral adjustment device and lifting device in the multi-degree-of-freedom adjustment platform. However, it is impossible to rotate the orientation of the rocket during the launch process, so that its launch direction can only be fixed to the installation direction of the platform. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides an electrical control system for storage and transportation integrated equipment.

[0004] The present invention is achieved through the following technical solutions.

[0018] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0019] An electrical control system for storage and transportation integrated equipment; including a crane hydraulic system and a platform hydraulic system, both of which are controlled by a hydraulic control system;

[0020] The hydraulic system of the crane includes a slewing hydraulic system, a luffing hydraulic system, and a boom telescopic system; the control system controls the slewing hydraulic system to drive the boom to slew, controls the luffing hydraulic system to change the angle of the boom, and controls the boom telescopic system to control the length of the boom;

[0021] The platform hydraulic control system includes a hydraulic system for the fuselage bracket lifting mechanism, a main bracket leg lifting hydraulic system, and an entry and exit box driving device hydraulic system; the bracket lifting mechanism hydraulic system controls the lifting and lowering of the bracket on the platform, the main bracket leg lifting hydraulic system controls the lifting and lowering of the platform, and the entry and exit box driving device hydraulic system drives the push rod on the bracket to push the container.

[0022] The swing hydraulic system drives the boom to swing through a hydraulic pump, controls the swing direction of the boom through a multi-way valve, brakes the swing of the boom through a speed reducer, and ensures a buffering function when the swing stops through a two-way swing buffer balance valve.

[0023] The luffing hydraulic system ensures the stable rise and fall of the boom during the luffing process through a balancing valve.

[0024] The multiple sets of oil cylinders in the boom telescopic system independently control each telescopic arm in the boom.

[0025] The hydraulic system of the fuselage bracket lifting mechanism includes a power station, a multi-way valve, a stop valve, a diverter valve, an electromagnetic reversing valve, a balancing valve, and a lifting cylinder. The power station and the multi-way valve are used to drive the lifting cylinder to control the lifting of the legs. The balancing valve is used to ensure that the cylinder outputs power smoothly. The logic switching of the stop valve and the electromagnetic reversing valve can realize the simultaneous lifting and lowering or the separate lifting and lowering of the leg cylinders.

[0026] The main bracket leg lifting hydraulic system includes a power station, a multi-way valve, a diverter valve, a balancing valve and four lifting cylinders. The diverter valve controls the diversion and collection of the hydraulic oil in the power station to control the lifting and lowering synchronization of the four cylinders, and the balancing valve ensures smooth rising and falling of the cylinders.

[0027] like Figure 1 As shown in the figure, the system uses a hydraulic pump station as the power source and an electric proportional multi-way valve as the control valve group to control the actions of the lifting mechanism, outrigger assembly, reducer, folding arm truck crane, etc. Various safety protection devices such as hydraulically controlled one-way balance valves, hydraulic locks and hydraulic brakes are installed on each actuator to ensure the safety and reliability of the system.

[0028] Slewing hydraulic system: The slewing oil circuit makes the boom slew and realizes the horizontal movement of heavy objects. The slewing system is mainly composed of a hydraulic pump, a multi-way valve, a two-way slewing buffer balance valve, a hydraulic motor and a hydraulic brake reducer. The slewing mechanism has a limited range of movement of heavy objects, but the required power is small, so the slewing of the truck crane is generally designed to be full-slewing, which can achieve a full 360° rotation and meet the output torque requirements. A two-way balance valve is designed in the system to ensure smooth rotation and a buffer function when the rotation stops.

[0029] Luffing hydraulic system: it changes the angle of the boom and lifts and lowers heavy objects. The truck crane is designed with a luffing system to increase the working space. A balance valve is designed in the luffing system to provide locking protection. The entire luffing requires the lifting and lowering arm to be stable and have good micro-movement. The luffing can be reliably locked at any allowable amplitude position and can micro-move under load.

[0030] Boom telescopic system: The telescopic system of this machine adopts multiple sets of cylinders to independently control the multi-stage arm mode, with strong load-bearing telescopic ability. A two-way balancing valve is designed in the hydraulic oil circuit to ensure that the load is reliably locked at any allowable amplitude.

[0031] Main bracket leg lifting system: The lifting platform oil circuit is used to control the rise and fall of the platform. The lifting platform system is mainly composed of a power station, a multi-way valve, a diverter valve, a balancing valve, a lifting cylinder, etc. The diverter valve can realize the diversion and collection of the hydraulic oil and realize the synchronous lifting of the four cylinders. The balancing valve can ensure the smooth rise and fall of the cylinder and can reliably ensure that the platform stays at any position.

[0032] Hydraulic system of the fuselage bracket lifting mechanism: the outrigger lifting oil circuit plays the role of lifting and lowering the outrigger. The outrigger lifting is divided into two situations: synchronous rising and falling and separate rising and falling. The outrigger lifting system is mainly composed of a power station, a multi-way valve, a stop valve, a diverter valve, an electromagnetic reversing valve, a balance valve, a lifting cylinder, etc. The balance valve can ensure the smooth rising and falling of the cylinder and can reliably ensure that the outrigger stays in any position. The logical switching of the stop valve and the electromagnetic reversing valve can realize the simultaneous rising and falling or separate rising and falling of the outrigger cylinders. The diverter valve can realize the diversion and collection of the hydraulic oil and realize the synchronous lifting of the four cylinders.

[0033] like Figure 3 and 4 The above is an implementation of the control system of the present application. In this implementation, the control system is made into a handheld remote control using wireless and wired instant communication. Table 1 is a button definition table of the handheld remote control.

[0036]

[0037] The in-and-out box drive control combination supplies power to the AC motor to realize the function of pushing out and pushing in the entire equipment. The in-and-out box drive control combination is equipped with a handheld wired remote control, which realizes the automatic in-and-out box function of the entire equipment through manual operation. The control combination is mainly composed of a handheld remote control box, a switching power supply, a relay, a circuit breaker, etc. The entire equipment can be pushed out and pushed in by operating the buttons on the remote control box. Push-out control: Press the "Push" button on the control box to control the AC motor to perform the push-out task. When the "Push-out" button is restored, the entire equipment stops pushing. Push-in control: Press the "Push-in" button on the control box to control the AC motor to perform the push-in task. When the "Push-in" button is restored, the entire equipment stops pushing in.
