Abstract
Description
Technical Field
[0001] The utility model relates to a refrigerated carriage technology, in particular to a meat hanging cold chain transport carriage. Background Art
[0002] Refrigerated trucks are an important means of transportation in cold chain transportation. Meat products in particular are often transported in refrigerated trucks by hanging. This can maintain ventilation, enable transportation at a lower temperature, and expand the scope of transportation.
[0003] Common cold chain transport carriages are all rectangular carriages that are fixed on the frame. The refrigerator is installed on one side of the carriage, and the heat exchanger is generally inside the carriage. Then the cold air is blown out by a fan and circulated in the carriage. This type of carriage is more common.
[0004] Whole slaughtered pigs, cattle and sheep are usually transported on hanging rails in meat processing plants, which can realize assembly line operation. Different steps are arranged sequentially around the hanging rails, which can realize automated production and save a lot of manpower. However, the last step of loading, that is, from the end of the meat processing plant to the cold chain carriage, inevitably requires manual handling. This is because the external tracks of the vehicle and the meat processing plant cannot be combined, and the hanging operation of meat products still requires a large number of people.
[0005] Currently, there is patent CN 219790330 U, a meat hook refrigerated car body and a refrigerated car, which discloses a device that can slide a hook into a shelf outside the car body, and the bottom of the loading and unloading mechanism can be flipped relative to the tail of the car body to enable the loading and unloading mechanism to flip between a first preset position and a second preset position, and the top of the loading and unloading mechanism has a hook groove corresponding to the slide rail and used to assemble the hook; when the loading and unloading mechanism is located at the first preset position, the hook can slide along the slide rail to the hook groove, and the hook can detach from the hook groove and enter the slide rail, saving a certain amount of manpower.
[0006] When the hanging rails in the carriage are normally installed, they cannot extend out of the carriage body, and it is impossible to make the hanging rails close to the external transport rails when the vehicle is reversing. Therefore, the hanging rails in the carriage cannot be directly connected with the external rails. On this basis, it is necessary to design a simple device to connect the hanging rails, hooks and external rails in the carriage. Whether loading or unloading goods, they can be directly connected to the external rails and directly connected to the product line. Utility Model Content
[0007] In order to solve the above technical problems, the utility model provides a meat hanging cold chain transport carriage, and its technical solution is as follows.
[0008] A meat hanging cold chain transport carriage, comprising a carriage, a hanging rail in the ceiling of the carriage, a door at the rear, and a sliding hook embedded in the hanging rail. The invention is characterized in that the end of the hanging rail is connected to a folding rail at the door of the carriage, and the folding rail is horizontally unfolded to connect to an external transport rail.
[0009] In this technical solution, the foam material prepared by supercritical foaming method in the compartment has a density of 0.05-0.20g / cm 3 , the heat transfer coefficient is 0.01-0.10W / m·K.
[0010] In the present technical solution, the material of the foaming material is selected from polypropylene (PP), polyethylene (PE), polystyrene (PS), polyvinyl chloride (PVC), polyetheretherketone (PEEK), polycarbonate (PC), polyurethane (PU), polyethylene terephthalate (PET), polylactic acid (PLA) or rubber material.
[0011] In the technical solution, the hanging rail is W-shaped, and folding rails are installed at both open ends.
[0012] In this technical solution, the hanging rail and the folding rail are connected by hinges on the inner wall of the compartment.
[0013] In the technical solution, the hanging rail is provided with a Y-shaped lock buckle at a position on the inner wall of the car body away from the hinge to tighten and release the folding track.
[0014] In the technical solution, the hanging rail is provided with a lock hole on the outer side wall of the compartment, and a flip lock buckle is extended outward from the corresponding position of the folded rail, and the lock buckle is flipped and inserted into the lock hole.
[0015] In the technical solution, a C-shaped elastic fixing bracket is inserted around the connection part between the hanging rail and the folding rail, and the C-shaped elastic fixing bracket wraps the rail to avoid the movement track of the sliding hook.
[0016] In the technical solution, the two side walls of the folding track are provided with mounting parts, on which two L-shaped brackets are movably mounted respectively, and the two L-shaped brackets form a door-shaped bracket to avoid the movement track of the sliding hook and the meat cargo.
[0017] In the technical solution, the mounting portion is a slot of the side wall, and the end of the L-shaped bracket has a corresponding pin.
[0018] In the present technical solution, the outer end of the folding track is a flexible docking part that docks with the external transport track. The internal shape of the flexible docking part matches the external dimensions of the folding slide rail and the external transport track. One end is sleeved on the folding track and the other end is sleeved on the external transport track. The bottom opening of the flexible docking part avoids the movement trajectory of the sliding hook.
[0019] In the technical solution, a lock hole is provided on the side wall of the external transport track, and a flip lock buckle extends outward from a corresponding position of the folded track, and the lock buckle is flipped and inserted into the lock hole for fixation.
[0020] Compared with the prior art, the utility model has the following beneficial effects:
[0021] The insulation material in the cold chain transport compartment is a foam material obtained by the supercritical foaming method, which involves dissolving a gas (usually carbon dioxide or nitrogen) in a liquid or supercritical fluid and then releasing the gas under specific conditions to form a foam structure. Supercritical fluid has the solubility of liquid and the diffusion capacity of gas, which enables it to form bubbles in the material more evenly, thereby obtaining a finer and more uniform foam structure. For example, when polypropylene material is prepared by supercritical foaming, a foam structure with a large number of tiny bubbles can be formed, which can significantly reduce the density of the material and make it lightweight. These bubbles also provide good thermal insulation properties because they can effectively prevent the transfer of heat. The gas between the bubbles (usually air or other gases) has a low thermal conductivity and can therefore serve as an insulation layer. Due to the bubble structure in polypropylene foam material, it has excellent thermal insulation properties. The bubbles can capture air to form an insulation layer, reducing the convection and radiation transfer of heat. In cold chain transportation, this material can effectively maintain the temperature of the goods, reduce energy consumption, and extend the shelf life of the goods. The polypropylene foam material produced by supercritical foaming has a low density, which means that it weighs less for the same volume. This is an important advantage for the transportation industry, as reducing weight can reduce transportation costs and improve transportation efficiency.
[0022] A track that can be folded horizontally is set at the outer end of the hanging rail of the carriage. When in use, the folding track is opened, which can be conveniently connected to the external hanging rail, so that goods can be loaded and unloaded directly without manual handling; the folding track adopts hinged docking. When not in use, the Y-shaped lock buckle stuck next to the internal guide rail will not loosen, ensuring safety and will not be lost; a flexible docking part and the external track are used for locking docking, and a small amount of error is allowed when docking the two ends of the guide rail, which is difficult to avoid in actual processing. The firmness of the docking is increased by flipping the lock buckle. The C-shaped elastic fixing bracket is inserted around the connection part of the hanging rail and the folding track, and combined with the flip lock buckle, the safety of the connection is increased. Movable supports can be added under the folding track to increase the load-bearing capacity of the folding track. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0033] The technical solution of the utility model is explained in the following with reference to the accompanying drawings.
[0034] like Figure 1 As shown, a meat hanging cold chain transport carriage includes a carriage 1, a door 5 is located opposite to the front of the carriage 4, a hanging rail 3 is provided in the ceiling 2 of the carriage 1, a door 5 is provided at the rear, a sliding hook 6 is embedded in the hanging rail 3, the end of the hanging rail 3 is connected to a folding rail 7 at the door 5 of the carriage 1, and the folding rail 7 is horizontally unfolded to connect to an external transport rail 8.
[0035] The compartment 1 is provided with thermal insulation material prepared by supercritical foaming method, and the specific materials that can be used include: polypropylene (PP), polyethylene (PE), polystyrene (PS), polyvinyl chloride (PVC), polyetheretherketone (PEEK), polycarbonate (PC), polyurethane (PU), polyethylene terephthalate (PET), polylactic acid (PLA) or rubber material. The performance parameters of the foam material are: density is 0.05-0.20g / cm 3, the heat transfer coefficient is 0.01-0.10W / m·K; it has the advantages of light weight and good heat insulation effect. The frameless space between the inner and outer skins of the carriage is filled with insulation materials to form an insulation layer. The insulation performance of the carriage mainly depends on the thermal conductivity and thickness of the insulation layer. Increasing the thickness of the insulation layer can reduce the heat transfer coefficient, but too thick the insulation layer will affect the loading volume of the carriage. The thickness of the insulation layer is generally between 50 and 120 mm, and the top and bottom plates of the carriage are usually thicker than other plates.
[0036] like Figure 2 As shown, the hanging rail 3 is W-shaped, and folding rails 7 are installed at both open ends. In this way, goods can be loaded and unloaded on both sides at the same time. At the same time, the position of the W-shaped hanging rail 3 cannot interfere with the folding rail 7, so the length of the middle track must be properly controlled, and the folding rail 7 cannot be extended indefinitely. As long as the folding rail 7 can be properly extended so that when the vehicle approaches the external transport track 8, the folding rail 7 can touch the external transport track 8, such a distance does not need to be very long.
[0037] like Figure 3 , Figure 4 As shown, the hanging rail 3 and the folding rail 7 are connected on the inner wall of the body 1 by a hinge 9. Such a structure can realize folding. The hanging rail 3 is provided with a Y-shaped lock 10 at a position away from the hinge 9 on the inner wall of the body 1. The Y-shaped lock 10 is elastic and can tighten and release the folding rail 7.
[0038] like Figure 5 , Figure 6 As shown, in order to maintain the connection reliability between the folding track 7 and the hanging rail 3, the hanging rail 3 is provided with a lock hole 11 on the outer wall of the car body 1, and a flip lock buckle 12 extends outward from the corresponding position of the folding track 7, and the lock buckle is flipped and inserted into the lock hole 11.
[0039] like Figure 8 As shown, the C-shaped elastic fixing bracket 13 is inserted around the connection part of the hanging rail 3 and the folding rail 7, and the C-shaped elastic fixing bracket 13 wraps the rail, half of which wraps the hanging rail 3 and the other half of which wraps the folding rail 7, and the bottom opening avoids the movement track of the sliding hook 6. The C-shaped elastic fixing bracket 13 further stabilizes the connection part between the two and keeps the rails reliable when docking.
[0040] like Figure 5 , Figure 6 , Figure 7The two side walls of the folding track 7 are provided with mounting parts 18, on which two L-shaped brackets 14 are movably mounted respectively, and the two L-shaped brackets 14 form a door-shaped bracket 14 to avoid the movement track of the sliding hook 6 and the meat cargo. The mounting part is a slot 16 of the side wall, and the end of the L-shaped bracket 14 has a corresponding pin 17. The function of the bracket 14 is that, because the folding track 7 is a cantilever structure, and the outer side is not strongly connected to the external transport track 8, when the loaded cargo passes, the folding track 7 may bend and deform, causing unstable transportation. In order to increase the stability of the cantilever of the folding track 7, a bracket 14 is added to the folding track 7. The purpose of the door-shaped bracket 14 is to avoid the hook and the passing cargo.
[0041] like Fig. 9 , Figure 1 , Figure 2 The outer end of the folding track 7 is a flexible docking part 15 docking with the external transport track 8. The internal shape of the flexible docking part 15 matches the external dimensions of the folding slide rail and the external transport track 8. One end is sleeved on the folding track 7, and the other end is sleeved on the external transport track 8. The bottom opening of the flexible docking part 15 avoids the movement track of the sliding hook. Similarly, the side wall of the external transport track 8 is provided with a lock hole 11, and a flip lock buckle 12 extends outward from the corresponding position of the folding track 7, and the lock buckle is flipped and inserted into the lock hole 11 for fixing.
