Description

Technical Field

[0001] This utility model belongs to the field of plasma bag transportation, and in particular relates to a plasma bag transportation vehicle. Background Technology

[0002] Low or ultra-low temperature environments can effectively inhibit bacterial growth and enzyme activity, which is a key means of maintaining the stability and bioactivity of plasma components. Therefore, in blood collection and supply institutions and clinical medical institution laboratories, plasma is generally stored in low-temperature or ultra-low-temperature freezers. These freezers are usually designed with multiple shelves to make full use of their vertical space, and their overall height is generally over 2 meters, with the highest shelf inside the freezer being about 1.7 meters.

[0003] Currently, the standard procedure for placing plasma into a refrigerator is as follows: First, each bag of plasma is placed individually into a tray or blood collection basket. Then, the trays or blood collection baskets carrying the plasma are stacked on a standard transport trolley and transported to the target refrigerator. Finally, the operator must remove the trays or blood collection baskets one by one from the trolley and place them manually onto the corresponding shelves inside the refrigerator.

[0004] This traditional operating mode has the following drawbacks: 1. The entire process involves multiple repetitive "take-and-place" actions, especially when handling large amounts of plasma, resulting in high labor intensity and low work efficiency. 2. For the upper space inside the refrigerator, operators often need to use stools, ladders, or other tools to elevate the area for placement. This not only increases the operator's labor intensity but also introduces the risk of falls from heights, which is extremely unsafe. During manual handling and lifting of trays or blood collection baskets, tilting and shaking are very likely to occur, causing the plasma bags inside to slip or even break. Plasma is a valuable biological resource; once damaged, it not only causes economic losses but may also pose a risk of biological contamination.

[0005] In addition, the patent with publication number CN216185216U discloses a plasma transport vehicle that is convenient for disinfection, but its core operation mode still falls within the scope of the above-mentioned "one-by-one pick-up and drop-off", which cannot achieve direct and stable transfer between the tray and the refrigerator shelf, and fails to fundamentally solve the problems of difficulty and low efficiency in high-level placement. Summary of the Invention

[0006] To address the problem that existing transport vehicles cannot achieve direct and smooth transfer between pallets and refrigerator shelves, this utility model provides a plasma bag transport vehicle, the technical solution of which is as follows: A plasma bag transport vehicle includes a frame device for support and fixation, and a chassis device. The frame device is equipped with a plurality of support devices for holding plasma bags, which are spaced apart along the height direction of the frame device. The chassis device has four electrically operated push rods spaced apart at its four corners. Each support device includes a support component with adjustable spacing that can slide up and down, and a tray is placed on the support component.

[0007] Furthermore, the frame device includes a support plate, four connecting seats are evenly arranged at the four corners of the bottom of the support plate, two force-applying components are symmetrically arranged at both ends of the support plate, and four columns are spaced apart at the four corners of the support plate.

[0008] Furthermore, the force-applying component includes a fixing frame, and a push rod is installed in the middle of the fixing frame; the surface of the column is provided with scale lines along the height direction.

[0009] Furthermore, the tray is symmetrically provided with two handles.

[0010] Furthermore, the support assembly includes a lifting plate, which has four sliding sleeves spaced apart at its four corners. The sliding sleeves are used to fit onto the column, and the column is provided with blind holes at intervals.

[0011] Furthermore, the surface of the lifting plate is covered with an anti-slip mat.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are: This invention, through its adjustable support device spacing, flexibly adapts to the varying heights of shelves inside different refrigerators, effectively enhancing the equipment's versatility and scenario adaptability. Simultaneously, utilizing a level support method, operators can smoothly and directly push the pallet horizontally onto the refrigerator shelf, achieving seamless transfer between the pallet and the shelf. This method not only significantly reduces handling effort and improves work efficiency but also completely solves the problem of climbing when placing pallets in high spaces within the refrigerator, greatly enhancing operational safety. The entire transfer process is stable and controllable, effectively avoiding tilting and shaking that may occur during traditional manual handling, thereby reducing the risk of plasma bags slipping and breaking, and contributing to ensuring the integrity and biosafety of plasma resources.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-5 A plasma bag transport vehicle includes a frame assembly, a chassis assembly, and multiple support devices. The frame assembly provides overall support and is connected to the chassis assembly below. Multiple support devices for holding plasma bags are installed at intervals along the height of the frame assembly. Their height can be pre-adjusted and fixed according to the common heights (e.g., 20cm, 25cm, 30cm) of the internal shelves of the target ultra-low temperature freezer, thereby achieving adaptation to the height difference of the freezer shelves before handling and creating conditions for subsequent smooth and direct transfer.

[0017] The chassis assembly includes a frame base plate 101, on which four omnidirectional wheels 10 are evenly mounted at the four corners, and four electric push rods 103 are also spaced apart at the four corners. The frame base plate 101 supports the extension and retraction of the electric push rods 103, and pushes the lifting plate 301 up and down through the connecting seat 202. During operation, by lifting the electric push rods 103, all the pallets 305 can be raised simultaneously to the same height as the target refrigerator shelf, eliminating the need for manual climbing and handling, and significantly reducing labor intensity and the risk of falls from heights.

[0018] The frame assembly includes a support plate 201 with two force-applying components symmetrically mounted at both ends and four uprights 203 fixed at the four corners. Each force-applying component consists of a fixing frame 205 and an anti-slip push rod 206 installed within it. Pushing the anti-slip push rod 206 allows the entire frame and chassis to move smoothly via the fixing frame 205. Each of the four uprights 203 has graduated markings 204 on its surface and blind holes 2031 spaced apart on its shaft. The spacing of the blind holes is based on common height differences in refrigerator shelves (e.g., one every 5cm), providing precise physical positioning for adjusting the height of the support devices. A connecting seat 202 at the bottom of the support plate 201 connects to the top of the electric push rod 103. The graduations 204 allow the spacing between the support devices to be pre-adjusted to perfectly match the internal shelf layout of the target refrigerator, enabling flexible adaptation of the equipment to different refrigerator sizes and improving its versatility.

[0019] The support device includes a support assembly and a support tray 305. The support assembly consists of a lifting plate 301 and four sliding sleeves 303 fixed at its four corners. The sliding sleeves 303 are fitted onto the upright 203 and can slide along it. A natural rubber anti-slip pad 302 is attached to the surface of the lifting plate 301 to effectively increase friction and prevent the support tray 305 placed on it from sliding. Screws 304 are installed on the sliding sleeves 303. After the sliding sleeve 303 slides along the upright 203 to a predetermined height (aligning with the scale mark 204 and the blind hole), tightening the screws 304 securely locks it onto the upright 203. Normally, this height can be adjusted once according to common refrigerator specifications and then fixed permanently without frequent changes. Handles 306 are symmetrically arranged on both sides of the support tray 305 for easy loading and unloading.

[0020] In actual operation, firstly, based on the height difference of the shelves in the target ultra-low temperature freezer, slide each sliding sleeve 303, and adjust the spacing of each lifting plate 301 to match the freezer shelf according to the scale mark 204, and tighten the screws 304 to fix it. Then, place the trays 305 containing plasma bags one by one on the anti-slip pads 302 of the lifting plate 301 using the handle 306. Next, the operator pushes the anti-slip push rod 206 to move the entire vehicle to the front of the target freezer door. Start the electric push rod 103 to raise it to an appropriate height, so that all the trays 305 are precisely aligned with the corresponding empty shelves inside the freezer. Finally, the operator only needs to apply horizontal force to push the trays 305 smoothly and directly from the lifting plate 301 into the freezer shelf, completing the batch transfer of plasma bags. The entire process avoids the repeated handling, lifting and delivery of pallets in traditional operations, and achieves seamless connection between pallets and refrigerator shelves. This not only greatly improves work efficiency, but also completely eliminates the risk of plasma bags slipping and breaking due to manual lifting or pallet tilting.
