[0029] Reference Figures 1 to 7 As shown, a solid water model storage and transfer vehicle includes a transfer vehicle body 1, a scissor lift frame 2, a storage rack 3, a movable plate 4, and a lifting drive mechanism 6. The bottom of the scissor lift frame 2 is installed on the top of the transfer vehicle body 1, and the top of the scissor lift frame 2 is connected to the bottom of the storage rack 3; the storage rack 3 is movably connected to the transfer vehicle body 1 via the scissor lift frame 2; the lifting drive mechanism 6 is installed on the transfer vehicle body 1, and one end of the lifting drive mechanism 6 is connected to the scissor lift frame 2 for driving the scissor lift frame 2 to move up and down; the front side of the storage rack 3 is open, and the other three sides of the storage rack 3 are provided with baffles 31, and the front opening end of the storage rack 3 is provided with a detachable protective plate 32; the movable plate 4 is movably connected to the storage rack and moves in and out towards the front opening end of the storage rack; the movable plate is used to stack solid water models 5.

[0030] The transport vehicle 1 includes a frame 11, two guide rods 12, a push rod 13, and four casters 14. The four casters 14 are installed at the four corners of the bottom of the frame 11. The guide rods 12 are cylindrical structures, and both guide rods 12 are vertically fixed to the rear end of the top of the frame 11 and are distributed on both sides. The baffle on the rear side of the storage rack 3 is fixedly connected with several sliding sleeves 32. The sliding sleeves 32 are divided into two rows corresponding to the positions of the two guide rods 12. The storage rack 3 is slidably connected to the two guide rods 12 through the sliding sleeves 33. The bottom of the storage rack 3 is connected to the top of the frame 11 through the scissor lift frame 2. The scissor lift frame is used to support the storage rack to move up and down along the frame, so that the opening end of the storage rack 3 can match the height of the radiotherapy bed, making it convenient for the movable flat plate 4 to slide out. The push rod 13 is installed at the rear end of the frame. The frame 11 includes a top plate and a bottom plate spaced apart vertically. The top and bottom plates are fixed at their four corners by welding columns, forming a mezzanine 111 between them. In actual manufacturing, vertical plates can be welded to three sides of the top and bottom plates to close them, and a hinged door can be provided on the remaining side, making the mezzanine 111 a storage space. A dedicated area can be set up inside the mezzanine to place items or counterweights.

[0031] The scissor lift 2 is driven to lift by the lifting drive mechanism 6. In this utility model, the lifting drive mechanism 6 can be implemented in two ways: manual and electric.

[0032] I. Manual lifting method: such as Figure 6 As shown, the lifting drive mechanism 6 can be implemented using a hand crank 61. For specific structure, refer to the scissor lift and rotating handle in Chinese Patent CN202123194830.7, or the hand crank structure of the lifting function of a hospital bed head. In this embodiment, two corresponding connecting seats 62 can be set at the bottom of the storage rack 3. The hand crank 61 has a Z-shaped structure, with one Z-shaped horizontal end rotatably connected to the two connecting seats 62. The middle part of the Z-shaped horizontal end is a threaded part, and a nut 63 is threadedly connected. The nut 63 is connected to the sliding rod above the scissor lift frame 2. By cranking the other Z-shaped horizontal end of the hand crank 61, the Z-shaped horizontal end is driven to rotate along the two connecting seats 62, thereby moving the nut 63 along the threaded part, thus realizing the lifting function of the scissor lift frame 2.

[0033] II. Electric lifting method, such as Figure 7As shown, the lifting drive mechanism 6 can be implemented using an electric push rod 64, equipped with a battery and a control switch. For specific connection structures and installation methods, refer to the postoperative bed care frame disclosed in Chinese Patent CN201821094424.9. In this embodiment, the electric push rod 64 is a servo electric push rod, capable of precisely controlling the extension length, and the battery is a rechargeable battery. The electric push rod 64 is fixed to the top of the frame 11. The extension end of the electric push rod 64 is connected to the slide bar below the scissor lift frame 2. The electric push rod 64 is electrically connected to the battery 65 via a control switch. The extension end of the electric push rod 64 drives the slide bar below the scissor lift frame 2 to slide, thereby realizing the lifting function of the scissor lift frame 2.

[0034] The storage rack 3 has a limiting groove 34 on each of its left and right inner walls, and the movable plate 4 is fitted into one of the limiting grooves 34 on each side. The bottom of the movable plate 4 has two rows of parallel pulleys 41, allowing it to move horizontally along the storage rack 3. A handle 42 is located at the center of the front side of the movable plate 4. To prevent the movable plate 4 from detaching from the limiting groove 34 when moving outwards, a chain 35 is connected to the rear end of the movable plate. One end of the chain is fixed inside the storage rack, and the chain 35 restricts the movable plate from sliding out of the storage rack, preventing it from falling completely out of the limiting groove 34. The movable plate 4 can slide directly onto the radiotherapy bed via the pulleys at its bottom, using the radiotherapy bed as support to prevent instability of the transport vehicle 1's center of gravity. As a preferred option, a counterweight can be installed in the interlayer to ensure the stability of the transport vehicle 1's center of gravity when the movable plate 4 slides out with the solid water phantom 5. In electric lifting mode, the mezzanine can also be used to fix and place the battery, which also plays a certain role in configuration and is conducive to center stability.

[0035] One end of the protective plate 32 is hinged to the bottom of the front opening of the storage rack 3, and both sides of the protective plate 32 are detachably connected to the corresponding side of the storage rack 3 via latches. When used for storage or transportation, the protective plate 32 is folded up to close the front opening of the storage rack to prevent the movable plate from sliding forward during transportation and causing the solid water model 5 to fall off.

[0036] This invention combines the functions of storing and transporting solid water phantoms 5. Solid water phantoms 5 can be directly transported to the radiotherapy bed for use by staff, eliminating the need for staff to repeatedly transport them from the warehouse and reducing their workload. When the solid water phantom 5 is needed, it is transported to the radiotherapy bed using the transport vehicle 1. The lifting mechanism drives the scissor lift 2 to adjust the height of the storage rack 3, aligning its upper surface with the radiotherapy bed. The movable flat plate 4 can then slide out of the storage rack and onto the radiotherapy bed. Staff can directly operate on the radiotherapy bed, stacking and arranging the solid water phantoms 5 in appropriate positions according to testing requirements, eliminating the need for transport from other locations, making operation more convenient and efficient. When used for storage or transport, a baffle 31 can be installed, forming a storage frame to prevent the water phantoms from tipping over during transport or storage. Radiotherapy beds in radiotherapy equipment typically have electric lifting and translation adjustment functions and can display the three-dimensional coordinates of the current position in real time. After use, the radiotherapy bed returns to its original position, meaning that the radiotherapy bed of the radiotherapy equipment returns to a fixed height after each use. In other words, the transport vehicle designed in this utility model only needs to be adjusted to the height of the storage rack 3 initially so that it corresponds to the original height of the radiotherapy bed. Subsequent uses do not require further adjustment of the scissor lift 2. Of course, height adjustment can also be performed without loading the solid water phantom.

[0037] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the scope of the technical solution of this utility model.
