Description

Technical Field

[0001] This invention relates to a large vehicle generator transport device, specifically to an adjustable loading and unloading transport device and transport method for vehicle-mounted generators. Background Technology

[0002] The vehicle-mounted generator is a core component of the automotive electrical system. Its function is to supply power to all electrical equipment (lighting system, air conditioning system, control system, etc.) and charge the battery to maintain electrical reserves when the engine is running normally. With the increasing functionality and intelligence of automobiles, especially the widespread use of special vehicles such as medical vehicles, communication command vehicles, field support vehicles, and large buses, the power demand for vehicle-mounted generators continues to grow. A single large generator can weigh hundreds of kilograms or even several tons, and its size has also increased accordingly. These large generators are usually fixedly installed inside the vehicle body, rigidly connected to the floor with bolts to ensure stability during driving. However, it is precisely because of their large size, heavy weight, and installation position deep inside the vehicle body that the generator's installation and removal are extremely difficult.

[0003] In existing technologies, the loading and unloading of large vehicle-mounted generators mainly relies on external lifting equipment such as forklifts and cranes, or is carried out by manual pushing and pulling. Due to the limited space and compact layout inside the vehicle, the generator is prone to collisions with the bulkhead, doors, or surrounding equipment when entering or leaving the vehicle, causing equipment damage or safety hazards. At the same time, forklifts, cranes, and other equipment are difficult to use in the field or in environments without power, and require multiple people to operate, resulting in low loading and unloading efficiency and high labor costs, which cannot meet the actual needs of rapid deployment and mobile support.

[0004] Therefore, there is an urgent need for a loading and unloading transportation device specifically designed for large vehicle-mounted generators, which can achieve smooth transfer of generators inside and outside the vehicle without the need for external large equipment, and can adapt to the differences in vehicle height for different vehicle models, so as to improve loading and unloading efficiency and reduce operational risks. Summary of the Invention

[0005] In view of the technical problems existing in the prior art, the purpose of this invention is to provide an adjustable loading and unloading transportation device and transportation method for vehicle-mounted generators, so as to realize the smooth transfer of generators inside and outside the vehicle without the need for large external equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An adjustable loading and unloading transport device for a vehicle-mounted generator includes a housing, four internal wheels, and four sets of external walking mechanisms. The internal wheels are located at the bottom of the housing and in front of the corresponding external walking mechanisms. Each set of external walking mechanisms includes a height adjustment component, a C-bolt, an upper limit buckle, a lower limit buckle, a movable support leg, and external walking wheels. The height adjustment component is located on the side of the housing and includes two L-shaped plates. Each L-shaped plate includes a vertical plate with a vertical waist hole and a horizontal plate with a through hole. The C-bolt includes a horizontal section and two vertical sections. The horizontal section passes through the waist hole of the two L-shaped plates, and the vertical section passes through the through hole of the two L-shaped plates from top to bottom. A nut is screwed into the end of the vertical section to support the horizontal plate. The upper end of the movable support leg is connected to the horizontal section of the C-bolt and rotates up and down around the horizontal section. When the movable support leg rotates to the bottom, it is locked by the lower limit buckle located on the side of the housing. When the movable support leg rotates to the top, it is locked by the upper limit buckle located on the side of the housing.

[0008] As a preferred option, the enclosure is cubic in shape, and the vehicle-mounted generator is fixed inside the enclosure.

[0009] As a preferred option, the external walking mechanism also includes a positioning plate, which is fixed to the side of the container, and the height adjustment component and the lower limit buckle are fixed to the positioning plate.

[0010] As a preferred embodiment, the positioning plate and the housing are connected by welding, the height adjustment component and the positioning plate are connected by welding, the lower limit buckle and the positioning plate are connected by welding, and the upper limit buckle and the housing are connected by welding.

[0011] As a preferred embodiment, the height adjustment component also includes a mounting plate that connects the two L-shaped plates; the mounting plate and the two L-shaped plates are an integral structure.

[0012] As a preferred embodiment, the upper limit buckle and the lower limit buckle have the same structure, including a limit groove plate and a limit locking plate. The limit groove plate is used for the insertion of the movable support leg. One end of the limit groove plate is extended and a locking slot is provided in the extended section. The other end of the limit groove plate is extended and bent, and is rotatably connected to the limit locking plate in the bent section. The limit locking plate is engaged or disengaged from the locking slot to achieve locking or unlocking.

[0013] As a preferred option, the limit plate is equipped with a manual lever.

[0014] As a preferred embodiment, when the movable support leg is flipped downwards, an ear plate is provided on the inner side of the lower end of the movable support leg.

[0015] A transportation method for an adjustable loading and unloading transportation device for a vehicle-mounted generator includes an unloading process and a loading process;

[0016] The unloading process includes:

[0017] Step 1: Using the internal wheels at the bottom of the container, push the container containing the generator towards the hatch from inside the carriage;

[0018] Step 2: After the external walking mechanism at the rear of the container is moved out of the cargo door, switch the movable support legs from the retracted state to the working state, so that the rear external walking wheels touch the ground to support the rear of the container.

[0019] Step 3: Continue pushing out the container until the external walking mechanism at the front of the container moves out of the car door. Switch the movable support leg at the front of the container from the retracted state to the working state, so that the external walking wheels at the front touch the ground to support the front of the container.

[0020] Step 4: The container is completely removed from the carriage and moved on the ground supported by the external wheels;

[0021] The loading process is the reverse of the unloading process.

[0022] As a preferred option, the specific steps for switching the mobile support leg from the storage state to the working state include: releasing the upper limit lock on the mobile support leg, allowing the mobile support leg to flip downwards around the horizontal section of the C-bolt; during the flipping process, the mobile support leg, under its own weight, drives the C-bolt to slide downwards along the waist hole until the external travel wheel contacts the ground; tightening the nut at the end of the C-bolt, with the nut supporting the box body through the height adjustment component.

[0023] The principle of this invention is:

[0024] This invention achieves smooth transfer of the vehicle-mounted generator between the inside and outside of the vehicle compartment through the time-sharing and switching of two sets of wheel systems. The bottom of the container is equipped with internal moving wheels for supporting and moving the container within the compartment; the sides of the container have foldable moving support legs, with external moving wheels at their bottoms. During unloading, the container is first supported by the internal moving wheels and moves within the compartment. Once the internal moving wheels have moved out of the door, the moving support legs flip from a retracted state to an operational state, and the external moving wheels take over the load. The container continues to be pushed out until all moving support legs are switched to the operational state, all internal moving wheels have moved out of the door, and the container is completely supported by the external moving wheels on the ground, thus achieving alternating load-bearing and segmented relay of the two wheel systems. Loading is performed in reverse order, with the two wheel systems switching sequentially to complete the loading of the generator from the ground to the vehicle compartment.

[0025] Meanwhile, this invention achieves adaptive adjustment of the mobile support leg's height relative to the ground through the cooperation of the waist hole and the C-bolt. The upper end of the mobile support leg connects to the horizontal section of the C-bolt, which passes through the vertical waist hole on the height adjustment component. When the nut is at the end, the C-bolt can slide freely within the waist hole. When the mobile support leg is flipped downwards from its retracted state, it automatically falls under its own weight, causing the C-bolt to slide downwards along the waist hole until the external wheels contact the ground. The height of the cargo box automatically adapts to the height difference between the cargo box floor and the ground. At this point, the nut at the end of the C-bolt is locked, and the nut transmits the weight of the cargo box to the mobile support leg through the height adjustment component, completing the locking process. This structure allows the mobile support leg's ground clearance to be automatically adjusted according to the actual ground position during operation, without manual intervention, and is suitable for loading and unloading needs of different vehicle models with varying cargo box heights.

[0026] The present invention has the following advantages:

[0027] 1. Simple tools required for operation: The generator can be loaded and unloaded by a single person by switching between two sets of wheel systems, without the need for external equipment such as forklifts or cranes.

[0028] 2. Does not occupy normal space: The support legs are stowed close to the side of the box and do not take up extra space in the vehicle body.

[0029] 3. Adaptive to ground height: The waist hole and C-bolt work together to allow the movable support leg to automatically descend under gravity until the external walking wheel contacts the ground, adapting to the height of different vehicle models.

[0030] 4. Simple structure and low cost: It has a fully mechanical structure with no electric or hydraulic components, and the parts can be mass-produced.

[0031] 5. Easy to operate: The limit plate can be quickly locked and unlocked, and tightening the nut is simple and can be done without professional training.

[0032] 6. Stable and reliable load-bearing capacity: The lower limit buckle ensures that the support leg is perpendicular to the ground, preventing slippage or displacement when bearing weight.

[0033] 7. The lower inner side of the movable support leg is provided with ear plates, which can be used to tie ropes between the ear plates to reinforce the structure, and can also be used as operating handles when the movable support leg is flipped. Attached Figure Description
