Description

Technical Field

[0001] This invention relates to the field of transportation equipment technology, and in particular to a rolling carrier for launch vehicles. Background Technology

[0002] During rocket manufacturing, the rocket body needs to be transported and stored short distances within the factory, typically using a gantry crane for transport, where equipment is installed and leveled. Existing gantry cranes, such as the rocket / missile support device and transfer vehicle disclosed in CN202010771031 and the solid-propellant rocket assembly gantry crane disclosed in CN202110322947, while capable of supporting and transferring the rocket body, have a simple structure and cannot allow for flexible adjustment of the rocket body during manufacturing. This necessitates constant repositioning of the rocket body using a crane, which is highly inconvenient. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a launch vehicle rolling frame with good structural rigidity and high-precision adaptive adjustment capabilities.

[0004] This invention is achieved through the following technical solution: The present invention provides a launch vehicle rolling support vehicle, including a frame and a rolling support system mounted on the frame for supporting the rocket body. The rolling support system includes a lifting component, a translation component and a rolling component. The lifting assembly includes a lifting drive and a lifting base. The lifting drive is a set and fixed on the vehicle frame. The top ends of the two lifting drives are connected to the lifting base. The lifting drive can drive the lifting base to move up and down. The translation component includes a translation drive, a translation guide rail, and a translation base. The translation guide rail is fixed on the lifting base and is perpendicular to the axis of the rocket body. The translation base is slidably connected to the translation guide rail. The translation drive is fixed on the lifting base and connected to the translation base. The translation drive can drive the translation base to slide horizontally along the translation guide rail. The rolling assembly includes a rolling base and a rolling structure. The rolling base is located at the top of the translation base, and the rolling structure is a set symmetrically arranged at both ends of the rolling base. A support channel capable of supporting the rocket body is formed between the two rolling structures.

[0005] To facilitate the automatic movement of the vehicle, two sets of walking components are provided at the bottom of the frame. The walking components include a walking servo motor, a walking reducer, a walking linkage, and walking wheels. The walking servo motor is connected to the walking reducer, and the walking reducer is connected to the walking wheels through the walking linkage. The walking servo motor can drive the walking wheels to rotate through the walking reducer and the walking linkage.

[0006] In order to achieve the switching of the master and slave functions of the vehicle walking, the walking speed reducer is connected to the walking linkage through the walking electromagnetic clutch.

[0007] To facilitate the weighing of the rocket body, a set of weighing sensors is symmetrically arranged at the top of the translation base, and the two weighing sensors are respectively connected to the two ends of the rolling base.

[0008] To prevent abnormal conditions from causing deformation and damage to the weighing sensor, several limiting supports are provided between the translation base and the rolling base.

[0009] To facilitate the rolling of the rocket body, in a preferred embodiment of the present invention, the rolling structure includes a rolling support, a rolling arm, and a rolling cylinder. The rolling support is fixed to the top of the rolling base, the rolling arm is rotatably connected to the rolling support, and the rolling arm has an arc-shaped support surface that fits against the surface of the rocket body. The rolling cylinder is a set, which is rotatably connected to the top and bottom of the rolling arm, and the rolling cylinder is in rolling contact with the surface of the rocket body.

[0010] To achieve automatic rolling of the rocket body, the rolling structure also includes a rolling drive, which includes a rolling servo motor, a rolling reducer, and a rolling electromagnetic clutch. The rolling servo motor is connected to the rolling reducer, and the rolling reducer is connected to one of the rolling cylinders through the rolling electromagnetic clutch. The rolling servo motor can drive the rolling cylinder to rotate through the rolling reducer and the rolling electromagnetic clutch, thereby causing the rocket body to rotate.

[0011] After the rocket body rolls into position, in order to lock it and ensure safety, the rolling assembly also includes a set of locking ring assemblies. The locking ring assemblies are fixed to the top of the rolling base, and the two locking ring assemblies are respectively arranged on one side of the rolling structure. The locking ring assemblies are provided with locking shafts that can lock the rocket body.

[0012] In order to measure the distance and center of gravity between the master and slave carriages in real time and ensure safety, the rolling base is equipped with an optical distance measuring sensor for measuring the distance and center of gravity between two adjacent carriages.

[0013] The beneficial effects of this invention are: the launch vehicle rolling frame adopts a modular, hierarchical, and open architecture design, which has good structural rigidity and high-precision adaptability and adjustment capabilities, meets the transportation, installation and testing of the rocket body during the processing, can ensure the stable operation of the system, is easy to expand and maintain, can achieve efficient, stable and reliable production process control, and meet the needs of modern industrial production.

[0015] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0016] like Figure 1 , Figure 2 The illustrated carrier rocket rolling support vehicle includes a frame 1 and a rolling support system mounted on the frame 1 for supporting the rocket body. The rolling support system includes a lifting component, a translation component, and a rolling component.

[0017] Specifically, the lifting assembly includes a lifting drive and a lifting base 2. The lifting drive is a set, fixed to both sides of the bottom end of the frame 1. The lifting drive uses a lifting mechanism 3, which is connected to the lifting base 2. The lifting mechanism 3 can drive the lifting base 2 to move up and down, realizing the lifting of the rocket body. In addition, a lifting proximity switch 22 and a lifting scale 23 are installed on the frame 1, and a horizontal proximity switch 24 and a horizontal scale 25 are installed on the lifting base 2. The horizontal and lifting strokes can be directly viewed on the lifting scale 23 and the horizontal scale 25, and the stroke can also be viewed on the display screen of the handheld control box. When any stroke exceeds the limit, the proximity switch will send a command to the PLC, and the motor will stop operating.

[0018] Specifically, the translation component includes a translation drive, a translation guide rail 7, and a translation base 5. The translation guide rail 7 is fixed to the top of the lifting base 2 and is perpendicular to the axis of the rocket body. The translation base 5 is slidably connected to the translation guide rail 7. The translation drive uses a translation servo motor 6, which is fixed to the lifting base 2 and connected to the translation base 5. The translation servo motor 6 can drive the translation base 5 to slide horizontally along the translation guide rail 7, thereby realizing the horizontal movement of the rocket body.

[0019] Specifically, the rolling assembly includes a rolling base 10 and a rolling structure. The rolling base 10 is disposed at the top of the translation base 5. A set of weighing sensors 8 are symmetrically arranged at the top of the translation base 5. The two weighing sensors 8 are respectively connected to the bottom ends of the rolling base 10. At the same time, several limiting supports 9 are provided between the translation base 5 and the rolling base 10 to prevent the weighing sensors 8 from deforming or being damaged due to abnormal conditions. An optical distance measuring sensor 4 is disposed on the rolling base 10 for measuring the distance between two adjacent frame cars. The optical distance measuring sensor 4 can realize the function of measuring the center of gravity position of the two frame cars. The rolling structure is a set, symmetrically arranged at both ends of the top of the rolling base 10. A support channel is formed between the two rolling structures to support the rocket body. The rolling structure includes a rolling support 11, a rolling arm 12, and a rolling cylinder 13. The rolling support 11 is fixed to the top of the rolling base 10. The rolling arm 12 is rotatably connected to the rolling support 11 by a pin, and the rolling arm 12 has an arc-shaped support surface that fits against the surface of the rocket body. The rolling cylinder 13 is a set, rotatably connected to the top and bottom ends of the rolling arm 12 respectively. The rolling cylinder 13 is in rolling connection with the surface of the rocket body.

[0020] Specifically, the bottom of the frame 1 is provided with two sets of walking components. The walking components include a walking servo motor 18, a walking reducer, a walking link 20, and a walking wheel 21. The walking servo motor 18 is connected to the walking reducer. The walking reducer is connected to the walking link 20 through a walking electromagnetic clutch 19. The walking link 20 is connected to the walking wheel 21. The walking servo motor 18 can drive the walking wheel 21 to rotate through the walking reducer and the walking link 20. A wheel locking device can be provided on the walking wheel 21.

[0021] It should be noted that when the rolling drum 13 is not powered, the launch vehicle rolling frame can be used as a driven frame, while when the rolling drum 13 is powered, the launch vehicle rolling frame can be used as an active frame.

[0022] When used as an active jack, the rolling structure also includes a rolling drive, which includes a rolling servo motor 14, a rolling reducer 15, and a rolling electromagnetic clutch 16. The rolling servo motor 14 is connected to the rolling reducer 15, and the rolling reducer 15 is connected to one of the rolling cylinders 13 (preferably the lower rolling cylinder in this embodiment) through the rolling electromagnetic clutch 16. The rolling servo motor 14 can drive the rolling cylinder 13 to rotate through the rolling reducer 15 and the rolling electromagnetic clutch 16, thereby causing the rocket body to rotate.

[0023] In addition, the rolling assembly also includes a set of locking ring assemblies 17, which are fixed to the top of the rolling base 10, and the two locking ring assemblies 17 are respectively arranged on one side of the rolling structure. The locking ring assembly 17 is provided with a locking shaft that can lock the rocket body.

[0024] When in use, the rocket carrier can transport the rocket body using a one-master-one-slave, one-master-two-slave, or one-master-three-slave linkage mode. The rocket body is placed on the rolling structure of the main carrier and slave carriers. The lifting platform 2 is driven up and down by the elevator 3 to achieve the lifting of the rocket body. The horizontal movement of the rocket body is achieved by the translation servo motor 6 driving the translation platform 5 to slide horizontally along the translation guide rail 7. When the rocket body needs to roll, the rolling servo motor 14 drives the rolling cylinder 13 to rotate through the rolling reducer 15 and the rolling electromagnetic clutch 16, thereby rotating the rocket body. The rolling electromagnetic clutch 16 can switch between the master and slave functions of the carrier movement.

[0025] It should be noted that each drive in this invention can be replaced by a cylinder, electric cylinder, motor, hydraulic cylinder, etc., combined with a connecting plate, coupling, etc., and is not limited to the relevant structures shown in the drawings; and each drive in this invention is equipped with a sensor at the corresponding position to sense whether the action is in place.
