Technical Field
[0001] This utility model belongs to the field of prefabricated house technology, and in particular relates to a RV lifting structure. Background Technology
[0002] Prefabricated houses are a new type of environmentally friendly and economical prefabricated housing, using color steel plates as the frame, sandwich panels as the enclosure material, and standardized modular series for spatial combination. Components are connected by bolts. They can be easily and quickly assembled and disassembled, achieving universal standardization of temporary buildings. This establishes an environmentally friendly, energy-saving, fast, and efficient construction concept, bringing temporary housing into a field of serialized development, integrated production, complete supply, and stockable, reusable, and standardized products.
[0003] When existing prefabricated houses need to be moved during use, they need to be lifted by a forklift into the cargo compartment of a transport vehicle, and then transported by the transport vehicle. The above-mentioned transfer method is not only time-consuming and labor-intensive, but also has low transfer efficiency and high transfer cost. Therefore, there is an urgent need for a RV lifting structure to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a RV lifting structure to solve the problem mentioned in the background art that when the RV needs to be moved during use, it is necessary to use a forklift to lift it into the compartment of a transport vehicle and then transport it by the transport vehicle, which is not only time-consuming and labor-intensive, but also has low transfer efficiency and high transfer cost.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A motorhome lifting structure includes a prefabricated house body. Two sets of support rods are symmetrically installed on both sides of the prefabricated house body. One end of each support rod is connected to a driving wheel. A winding mechanism is provided between the support rod and the prefabricated house body. The winding mechanism includes:
[0007] A winch is used to pull a rope to drive the support rod;
[0008] Drive motor, used to drive the winch to rotate;
[0009] A fixed pulley is used to guide the rope.
[0010] By adopting the above technical solution, when the prefabricated house needs to be moved, the drive motor is controlled to work, causing the winch to rotate, which in turn causes the winch to wind up the rope. During the winding process, the fixed pulley guides it, and at the same time, the support rod drives the traveling wheel to move inward, so that the prefabricated house gradually stands upright until it is in a fully upright position. At this point, the prefabricated house can be moved simply by connecting it to the transport vehicle.
[0011] Furthermore, the winding assembly also includes:
[0012] The gearbox can save effort when operating manually during a power outage;
[0013] The handwheel can drive the winch to rotate via the gearbox during a power outage.
[0014] By adopting the above technical solution, the winch can be rotated by the handwheel and the gearbox in the event of a power outage, thereby winding up the rope.
[0015] Furthermore, the support rod is designed as a hollow tube structure, which reduces weight while maintaining necessary strength.
[0016] By adopting the above technical solution, the usage status of the prefabricated house can be adjusted by changing the tilt state of the support rod.
[0017] Furthermore, a locking mechanism is provided between the support rod and the prefabricated house body, the locking mechanism including:
[0018] Fixed pins are symmetrically arranged on both sides of the prefabricated house body;
[0019] The pin hole is formed on the support rod and corresponds to the position of the fixing pin and matches its specifications.
[0020] By adopting the above technical solution, when the support rod is in a vertical position, the fixing pin can be inserted into the pin hole to lock the support rod.
[0021] Furthermore, the surface of the driving wheels is made of a special rubber material to increase friction and prevent slippage.
[0022] By adopting the above technical solution, the driving wheels can support the prefabricated house body during the transfer process.
[0023] Furthermore, an electrical control box is installed on one side wall of the prefabricated house. The electrical control box has a built-in electrical control system and is powered by a battery inside the external shed.
[0024] By adopting the above technical solution, the electrical control box is connected to the battery inside the shed to provide the required power, and the operation of the drive motor is controlled by the control system inside the electrical control box.
[0025] Furthermore, a connecting ring is welded to the middle of one side wall of the support rod, and the connecting ring is made of high-strength material to ensure its strength.
[0026] By adopting the above technical solution, the connecting ring facilitates the connection between the prefabricated house body and external transport vehicles, thereby enabling its transfer.
[0027] Compared with the prior art, the beneficial effects of this utility model embodiment are as follows:
[0028] This invention involves installing driving wheels on both sides of the prefabricated house. The driving wheels are connected to the support rods on both sides. By pulling ropes with a winch, the support rods move the driving wheels inward, gradually making the prefabricated house stand upright. Once fully upright, the prefabricated house is locked in place by fixing pins and pin holes, allowing it to be moved. During use, simply moving the driving wheels to the sides until the prefabricated house contacts the ground is sufficient. This not only makes the operation simple but also highly efficient, effectively improving the usability of the prefabricated house. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0036] like Figures 1-4As shown, a motorhome lifting structure includes a prefabricated house body 8. Two sets of support rods 2 are symmetrically installed on both sides of the prefabricated house body 8. One end of each support rod 2 is connected to a driving wheel 1. A winding mechanism 3 is provided between the support rods 2 and the prefabricated house body 8. The winding mechanism 3 includes: a winch 301 for pulling a rope 5 to drive the support rods 2; a drive motor 302 for driving the winch 301 to rotate; and a fixed pulley 303 for guiding the rope 5. The winding assembly also includes: a gearbox 304, which can save effort when operating manually during a power outage; and a handwheel 305, which can drive the winch 301 to rotate via the gearbox 304 during a power outage.
[0037] The specific steps are as follows:
[0038] The drive motor 302 is controlled to operate, causing the winch 301 to rotate, which in turn causes the winch 301 to wind up the rope 5. During the winding process, the fixed pulley 303 guides the rope, while the support rod 2 drives the traveling wheel 1 to move inward, so that the prefabricated house body 8 gradually stands upright until it is fully upright. At this point, the prefabricated house body 8 can be transferred by simply connecting it to the transport vehicle. During use, the traveling wheel 1 can be moved to the sides to bring the prefabricated house into contact with the ground. In the event of an unexpected power outage, the winch 301 is rotated by the handwheel 305 and the gearbox 304 to wind up the rope 5.
[0039] like Figures 1-3 As shown, in one embodiment, the support rod 2 is designed as a hollow tube structure, which reduces weight while maintaining necessary strength. A locking mechanism 4 is also provided between the support rod 2 and the prefabricated house body 8. The locking mechanism 4 includes a fixing pin 401, which is symmetrically arranged on both sides of the prefabricated house body 8; and a pin hole 402, which is formed on the support rod 2 and corresponds to the fixing pin 401 in position and specification. The surface of the driving wheel 1 is made of special rubber material to increase friction and prevent slippage.
[0040] The specific steps are as follows:
[0041] When the support rod 2 is in a vertical position, the fixing pin 401 can be inserted into the pin hole 402 to lock the support rod 2, thereby enabling the driving wheel 1 to support the prefabricated house body 8 and move it.
[0042] like Figure 1 and Figure 2 As shown, in one embodiment: an electrical control box 6 is installed on one side wall of the prefabricated house body 8. The electrical control box 6 has a built-in electrical control system and is powered by a battery in the external shed. A connecting ring 7 is welded to the middle of one side wall of the support rod 2. The connecting ring 7 is made of high-strength material to ensure its strength.
[0043] The specific steps are as follows:
[0044] The electrical control box 6 is connected to the battery inside the shed to provide the required power. The control system inside the electrical control box 6 controls the operation of the drive motor 302. The connecting ring 7 facilitates the connection between the prefabricated house body 8 and the transport vehicle, thereby realizing the transfer of the prefabricated house body 8.
[0045] In summary, the working principle of this RV lifting structure is as follows: During the use of the prefabricated house body 8, when it is necessary to move the prefabricated house body 8, the electrical control box 6 is connected to the battery in the RV to provide the required power. Then, the control box controls the drive motor 302 to work, which drives the winch 301 to rotate, thereby causing the winch 301 to wind up the rope 5. During the winding process, the fixed pulley 303 guides it, and at the same time, the support rod 2 drives the traveling wheel 1 to move inward, so that the prefabricated house body 8 gradually stands upright. When the support rod 2 is in a vertical position, the fixing pin 401 can be inserted into the pin hole 402 to lock the support rod 2. Then, the prefabricated house body 8 is connected to the transport vehicle through the connecting ring 7 for transfer. During use, it is only necessary to move the traveling wheel 1 to the sides to make the prefabricated house contact the ground. In the event of an unexpected power outage, the handwheel 305 and the gearbox 304 drive the winch 301 to rotate, thereby winding up the rope 5.
[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
