[0056] In this embodiment, the component to be mounted 16 can be a subframe. The connection method between the various structures in the movable support assembly, the horizontal adjustment assembly, and the lifting assembly is as follows: the components are welded together, and the components are assembled with bolts. Considering stress and transportation, this distribution results in better connection, assembly, and use.

[0057] Compared with existing technologies, this type of loading and unloading equipment for mobile refueling vehicles is used for the assembly of superstructures of large vehicles.

The difference is that the mobile support assembly further includes a mobile component 1, an upper load-bearing beam 9, and front and rear support components. The mobile component 1 is connected to both the side beam assembly 4 and the control assembly, and is electrically connected to the control assembly.

The output end of the servo motor is connected to a gear, and the load-bearing rail 8 is provided with a rack that engages with the gear. The servo motor drives the gear to rotate, and the rotation of the gear realizes the relative displacement between the gear and the rack, thereby realizing the sliding of the traveling frame assembly 10 in the forward and backward direction. The side pull driver 12 is a side pull cylinder that realizes the left and right fine adjustment of the side travel support frame 11. Several side pull drivers 12 are provided.

[0061] As another embodiment of the present invention, the structure of the loading and unloading equipment for mobile refueling vehicles is basically the same as that in the above embodiments, except that the lifting assembly includes a first lifting frame 14, a second lifting frame 15, and a lifting cylinder 17, wherein the first lifting frame 14 is connected to and corresponds one-to-one with the side travel support frame 11; the second lifting frame 15 is slidably connected to the first lifting frame 14 and engages with the component to be loaded 16; the lifting cylinder 17 is connected to both the first lifting frame 14 and the second lifting frame 15, and is used to drive the second lifting frame 15 to slide relative to the first lifting frame 14.

[0062] In this embodiment, the lifting cylinder 17 is a telescopic hydraulic cylinder that telescopically achieves the function of lifting a 15-ton superstructure. Through the cooperation between the lifting cylinder 17, the first lifting frame 14, and the second lifting frame 15, the superstructure 16 to be lifted can be well fixed, avoiding situations such as the hook falling off or hitting the chassis during lifting or moving.

[0063] In another embodiment of the present invention, the structure of the loading and unloading equipment for the mobile refueling vehicle is basically the same as that in the above embodiment, except that the front and rear support components include vertical beams 5 and horizontal beams 6, wherein the vertical beams 5 are connected to the moving component 1 and correspond one-to-one with the moving component 1; the horizontal beams 6 are connected to all the vertical beams 5 and to the lifting component, and are used to support the lifting component. There are two front and rear support components, which are respectively located at both ends of the moving component 1.

[0064] As another embodiment of the present invention, the structure of the loading and unloading equipment for the mobile refueling vehicle is basically the same as that in the above embodiment, except that the control components include an electrical cabinet 2, a hydraulic system cabinet 3, and a strobe warning light 7. The electrical cabinet 2 is mounted on the moving component 1 and electrically connected to both the moving component 1 and the travel drive 13, used to transmit working signals and provide power to the connected equipment. The hydraulic system cabinet 3 is mounted on the moving component 1 and electrically connected to the electrical cabinet 2, and is also connected to the side pull drive 12 and the lifting cylinder 17, used to control the operation of the hydraulically related structures within the device. The strobe warning light 7 is mounted on the crossbeam 6 and electrically connected to the electrical cabinet 2. Anything that can achieve the aforementioned performance functions of the electrical cabinet 2 and the hydraulic system cabinet 3 is within the scope of protection of this application.

[0065] It should be noted that a warning light will illuminate when the equipment tilts; this is existing technology and will not be discussed further here.

[0066] In this embodiment, the power source of the device adopts the method of energy storage and workshop power switching, and is located in electrical cabinet 2 to ensure the long-term operation of the device. When working, the power supply is provided by a storage battery, and in an emergency, an external power supply can be used, which can be introduced by quickly plugging in the connector.

[0067] As another embodiment of the present invention, the structure of the loading and unloading equipment for the mobile refueling vehicle is basically the same as that in the above embodiment. The difference is that the mobile component 1 includes a support beam, a set of universal wheels, and a steering wheel. The support beam is connected to the control component, the front and rear support components, and the side beam component 4. The set of universal wheels is connected to the support beam. The steering wheel is connected to both the support beam and the set of universal wheels, and is electrically connected to the control component to control the start and stop of the set of universal wheels.

[0068] In this embodiment, the moving component 1 is located at the bottom of the vehicle frame, and the steering wheels are horizontal steering wheels, with four of them. The horizontal steering wheels are highly integrated mechatronic products, including a drive mechanism and speed feedback, a steering mechanism and position feedback, a limit device, and a braking structure. Through drive control, the travel speed and direction of the steering wheels can be precisely controlled. It should be noted that the horizontal steering wheels are prior art; prior art drawings are attached. Figure 6 As shown, no further explanation will be given here.

[0069] Due to the long body frame, four sets of omnidirectional wheels are installed to ensure the rigidity of the body and the load-bearing capacity of the moving component 1. The moving component 1 can realize the functions of forward, backward, lateral movement, steering, and braking of the whole vehicle. The maximum driving speed is 4 km / h when unloaded and 3 km / h when loaded. Stepless speed regulation can be achieved within the maximum driving speed range.

[0070] As another embodiment of the present invention, the structure of the loading and unloading equipment for the mobile refueling vehicle is basically the same as that in the above embodiment. The difference is that the side beam assembly 4 includes a connecting beam, a first fixed beam, and a second fixed beam. The connecting beam is connected to both the upper load-bearing beam 9 and the horizontal adjustment assembly. One end of the first fixed beam is connected to the moving assembly 1, and the other end is connected to the connecting beam. One end of the second fixed beam is connected to the moving assembly 1, and the other end is connected to the connecting beam. The connecting beam, the first fixed beam, the second fixed beam, and the moving assembly 1 are connected to form an isosceles trapezoidal structure. The plane of the isosceles trapezoid is at a certain angle to the direction in which the lifting assembly moves the loading component 16.

[0071] In this embodiment, several first and second fixed beams are provided along the direction of the connecting beams. The side beam assembly 4 also includes reinforcing beams that are simultaneously connected to several first and second fixed beams. Several reinforcing beams are provided along the direction of the height of the isosceles trapezoid. The side beam assembly 4 is supported by an inclined inner isosceles trapezoid, which increases the beam cross-sectional size and makes the structure more stable.

[0072] As another embodiment of the present invention, the structure of the loading and unloading equipment for mobile refueling vehicles is basically the same as that in the above embodiments. The difference is that the second lifting frame 15 includes a sliding beam, a working beam, and a working arm. The sliding beam is connected to the lifting cylinder 17 and slidably connected to the first lifting frame 14. There are several sliding beams. The working beam is connected to several sliding beams at the same time. The working arm is connected to the working beam and the loading part 16 at the same time, and there are several working arms along the setting direction of the working beam. The working arm and the sliding beam are arranged in an L-shaped structure.

[0073] The working process of this device is as follows:

[0074] 1) The device is controlled by a remote controller. The moving component 1 enables the unmanned vehicle to move, turn, or lateral. Upon reaching the designated position, the steering wheel brakes, and the vehicle stops. The controller is installed outside the device and is existing technology, so it will not be described in detail here.

[0075] 2) Drive the vehicle's subframe chassis assembly into (reverse into) the lifting fixture and stop. Use bolts to insert into the bolt holes on the equipment to be lifted, and test to confirm if the position needs adjustment. Determine whether to move the lifting fixture based on the vehicle's position. After ensuring the lifting fixture is safely braked, control the horizontal adjustment components of the fixture body to lower the lifting cylinder 17, preparing for the frame lifting operation.

[0076] 3) Lifting: The lifting arms extend from both sides into the subframe floor, securing the three main beams of the vehicle subframe. After ensuring safe fixation and meeting lifting conditions, the lifting device uses four hydraulic jacks to lift the subframe. Once the vehicle subframe assembly is lifted a certain height from the chassis, the lifting assembly stops, and the chassis drives out of the lifting fixture. During the chassis exiting the lifting fixture, the lifting device uses hydraulic locks to ensure the vehicle subframe does not move. The hydraulic locks are existing products and not the subject of this application; therefore, they will not be discussed further here.

[0077] 4) The lifting tooling car can carry the vehicle subframe and move it forward, backward, up, and down at a certain safe speed.

[0078] 5) Lowering: The vehicle chassis assembly drives into (reverses into) the lifting tool and stops. After roughly aligning the position, the lifting arm is lowered. After lowering to a certain height, the leveling adjustment component is operated to ensure that the subframe and chassis are installed in the required positions. The lifting device continues to lower until the subframe is safely placed on the vehicle chassis. During this process, the position of the subframe may need to be continuously adjusted using the fine-tuning device as needed.

[0079] 6) After the subframe is fixed to the chassis, drive away from the lifting fixture. It should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention.
