Description

Technical Field

[0001] This invention relates to the field of transportation equipment technology, and more particularly to a vehicle for transporting fluid media. Background Technology

[0002] Driven by my country's urbanization rate and rising consumption levels, the petrochemical market is developing rapidly, and the industry's demand for hazardous chemical logistics is continuously increasing.

[0003] In the future, as the hazardous chemicals industry continues to strengthen its supervision of vehicle safety and standardized transportation, flammable liquid transport vehicles, a type of hazardous materials transport vehicle, are specifically used for transporting flammable liquids such as gasoline and diesel. Due to the special nature of the hazardous materials transportation market, flammable liquid transport vehicles have strict requirements for vehicle safety, reliability, and other performance aspects. They usually use tank containers to load flammable liquids, which are heavy and result in a large total vehicle mass, making them unsuitable for the demand for portable gasoline cans in cities.

[0004] Currently, tank trucks are commonly used in the industry to transport flammable liquids. The main tank materials are aluminum alloy, 304 stainless steel, and 316 stainless steel. Different materials are used depending on the medium. Tanker trucks frequently transport gasoline and diesel. While gasoline and diesel have relatively stable physical properties and are less corrosive to steel, their flammability and explosiveness require special design. For example, the friction from surges inside the tank must not generate excessive static electricity, otherwise the medium could explode. Therefore, most gasoline and diesel transport vehicles use aluminum alloy as the tank material. Aluminum alloy is easy to dissipate static electricity from friction with oil, and its light weight allows for a larger medium carrying capacity, offering various practical advantages. The main aluminum alloy material used in domestic liquid tanker trucks is grade 5083 aluminum alloy.

[0005] Using tank containers to transport flammable liquids has the following main technical disadvantages:

[0006] 1. Due to its large weight, large size, and high center of gravity, the vehicle is prone to overloading and exceeding weight limits, which can lead to risks of rollover and loss of control when turning.

[0007] 2. Randomly changing the loading medium of vehicles can lead to problems such as tank corrosion, leakage, and loading / unloading blockage. On the one hand, it can cause the whole vehicle to be overloaded and exceed the limits, increasing the risk of rollover and loss of control.

[0008] 3. When welding the tank body to the chassis, there are defects such as incomplete penetration, incomplete fusion, slag inclusion, and undercut. When the vehicle is running, these defects will cause stress concentration under complex stress, which will become the source of cracks in the weld.

[0009] Overcoming at least one of the above-mentioned defects has been a technical issue that has been of great concern to those skilled in the art. Summary of the Invention

[0010] The purpose of this invention is to provide a vehicle for transporting fluid media that offers small-package transportation and high safety performance.

[0011] This invention provides a vehicle for transporting fluid media, comprising the following components:

[0012] The carriage has a door on at least one side wall that can be opened or closed;

[0013] The main support is rotatably supported inside the carriage, with the rotation axis along the vertical direction. The main support is provided with an installation station for placing several containers; wherein the containers are capable of holding the fluid medium.

[0014] A locking component is used to lock or unlock the container at the installation station;

[0015] A limiting component is used to position the main body of the bracket in the carriage to restrict relative rotation between the two.

[0016] Compared to existing technologies that use a single filling tube to transport liquids, the vehicle in this invention is equipped with several container installation stations, carrying multiple containers containing fluid media. Because the support body with the installation stations can rotate relative to the vehicle compartment, each container on the support body can be placed or removed from the same side of the compartment. The locking component in this invention positions the container at the installation station, and the limiting component locks the support body to the position of the compartment, thus improving the safety of vehicle transportation. This achieves miniaturization, lightweighting, and a lower center of gravity for transporting flammable liquids, reducing transportation risks. Furthermore, the containers allow for small-package transport of flammable liquids, and all portable gasoline cans can be retrieved and placed on one side of the vehicle for customer convenience. By storing different numbers of portable gasoline cans, it meets customers' needs for various quantities of flammable liquids.

[0017] Optionally, the bottom of the support body is provided with at least two casters, each caster being arranged circumferentially, and the support body is supported on the bottom wall of the carriage by the casters.

[0018] Alternatively / and, the rotating shaft is a shaft body, the upper end of which is rotatably mounted to the top wall of the carriage via a bearing, and the lower end of which is rotatably mounted to the bottom wall of the carriage via a bearing. The main body of the support is fixedly connected to the shaft body, and the main body of the support rotates around the central axis of the shaft body.

[0019] Optionally, the support body is provided with at least two support plates, the support plates are capable of accommodating N containers, and each container is supported on the support plate;

[0020] Alternatively and / or, along the length of the vehicle, the number of the support bodies is at least two.

[0021] Optionally, the limiting component includes a first hook and a second hook, one of which is fixed to the support body and the other is fixed to the bottom wall of the carriage. The first hook and the second hook cooperate to restrict the rotation of the support body relative to the carriage.

[0022] Optionally, the locking component includes a fence post and a constraint assembly. Each side of the support body is provided with the fence post, and both ends of the fence post are hinged to the support body. The constraint assembly is used to constrain the fence post to a first position. When the fence post is in the first position, the fence post can restrict the outward displacement of the container. When the fence post is rotated to a second position, it avoids the outward movement path of the container.

[0023] Optionally, some of the fence posts are further provided with bending rods, which further limit the corresponding containers in the vertical or height direction.

[0024] Optionally, the constraint component includes a resilient pin that abuts against the fence post to limit the rotation angle of the fence post relative to the support body.

[0025] Optionally, the elastic pin includes a limiting pin, a spring, and a mounting frame. The mounting frame is fixed to the bracket body, and the limiting pin is mounted on the mounting frame via the spring. The limiting pin can reciprocate in the vertical direction, and the abutment of the limiting pin with the fence post is located outside the mounting frame.

[0026] Optionally, the locking component includes a locking pin, which is mounted on the bracket body and is movable horizontally relative to the bracket body.

[0035] In the description of this application, it should be noted that, in the embodiments of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0036] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] Please refer to Figures 1 to 5 , Figure 1 This is a partial structural schematic diagram of a vehicle used for transporting fluid media in one embodiment of the present invention; Figure 2 for Figure 1 A frontal view diagram; Figure 3 for Figure 1 A structural diagram excluding the side walls and top wall of the carriage; Figure 4 for Figure 1 A structural diagram excluding the carriage section; Figure 5 for Figure 4 Enlarged view of a portion of point A in the middle.

[0038] This invention provides a vehicle for transporting fluid media, mainly comprising a cargo box 1, a support body 2, locking components, and limiting components. The fluid media can be flammable liquids such as gasoline and diesel, or gas-liquid mixtures such as liquefied petroleum gas.

[0039] The carriage 1 can be a fully enclosed carriage 1, including a top wall 11, a bottom wall 14, and four side walls surrounding the top wall 11 and the bottom wall 14. The four side walls may include two parallel first side walls 12 extending along the length of the carriage, and two end walls 13 connecting the ends of the two first side walls. In this invention, at least one side wall of the carriage 1 has a door that can be opened or closed, the door including an upper door 121 and a lower door 122 that open or close opposite to each other. A specific example of a door on a first side wall is given herein. By opening the door, containers inside the carriage 1 can be removed and placed in.

[0040] In this invention, the support body 2 is rotatably supported inside the carriage 1, with the rotation axis running vertically. This means the support body 2 can rotate relative to the carriage 1 around a vertical axis, typically the central axis of the support body 2. There are various ways to rotatably install the support body 2 to the carriage 1. In one specific example, a shaft 26 can be provided, with the support body 2 fixedly connected to it. The two ends of the shaft 26 are rotatably mounted to the top wall 11 and bottom wall 14 of the carriage 1 via bearings, respectively. Only the bearing 25 at the upper end of the shaft 26 is shown in the figure. The rotation axis is the central axis of the shaft. Of course, the support body 2 can also be rotatably installed to the carriage 1 in other ways, such as by mounting it to the carriage 1 via a turntable, etc.

[0041] The support body 2 of this invention is provided with an installation station for placing several containers, meaning that the support body 2 can hold several containers; wherein the containers can hold fluid media. In this embodiment, the fluid media is contained in several containers. The containers placed on the support body 2 can be of the same size and shape, i.e., containers of the same specification, or they can be containers of different sizes and shapes, i.e., containers of different specifications. The figure shows two specifications of containers installed: a first specification container 3 and a second specification container 4.

[0042] The locking component in this invention is used to lock or unlock the container at the installation station. That is, the relative position of the container and the support body 2 is locked by the locking component. When the container needs to be disassembled, the locking component can be disassembled.

[0043] The limiting component in this invention is used to position the support body 2 on the carriage 1 to restrict the relative rotation between the two.

[0044] Compared with the existing technology of transporting liquids with a single filling tube, the vehicle in this invention is equipped with several container installation stations, carrying multiple containers containing fluid media. Because the support body 2 with the installation stations can rotate relative to the carriage 1, each container on the support body 2 can be picked up and placed at the same door opening position on the same side of the carriage 1. The locking component in this invention positions the container at the installation station, and the limiting component locks the support body 2 and the carriage 1 in position, which can improve the safety of vehicle transportation.

[0045] In one specific example, the bottom of the support body 2 of a vehicle used for transporting fluid media is provided with at least two casters 20. The casters 20 are arranged circumferentially. The figure shows an example of a support body 2 with four casters 20, located at the four corners of the support body 2. Of course, the number of casters 20 can be determined according to the specific product, as long as reliable rolling and stable support can be achieved. The casters 20 can also be evenly distributed circumferentially, and the support body 2 is supported by the casters 20 against the bottom wall 14 of the carriage 1. Correspondingly, an annular raceway can be provided on the inner surface of the bottom wall 14 of the carriage 1 facing the support body 2, and the casters 20 move along the annular raceway 15, which can improve the rolling flexibility of the casters 20.

[0046] In one specific example, the support body 2 is provided with at least two layers of support plates 27. The figure shows two layers of support plates 27, which are roughly the same in shape. Of course, the size and shape of each layer of support plates 27 can also be different. The support plates 27 can accommodate N containers, and each container is supported by the support plate 27. The number of layers of the support body 2 is related to the size of the containers, which can be reasonably designed according to the size of the containers being transported.

[0047] Furthermore, along the length of the vehicle, the number of support bodies 2 can be two or more, that is, the number of support bodies 2 along the length of the vehicle is at least two.

[0048] Of course, if both sides of the carriage 1 have doors, two rows of support bodies 2 can be arranged along the width of the vehicle.

[0049] In one specific example, the limiting component may include a first hook 7 and a second hook 16, one of which is fixed to the support body 2 and the other is fixed to the bottom wall 14 of the carriage 1. The first hook and the second hook cooperate to restrict the rotation of the support body 2 relative to the carriage 1. The hook method achieves the positioning of the two components, which is simple in structure and occupies little space.

[0050] In the above embodiments, the locking component includes a fence post and a constraint assembly 6. Each side of the support body 2 is provided with a fence post, and both ends of the fence post are hinged to the support body 2. Taking the first positioning bracket 21 as an example, the two ends of the first fence post 211 of the first positioning bracket 21 are hinged to the support body 2 via a hinge shaft 21a. For ease of hinge connection, the support body 2 can be flexibly configured for reasonable installation. As shown in the figure, the support body 2 is specially provided with a connecting beam 212 that is hinged to the first fence post 211. The constraint assembly is used to constrain the fence post to a first position. When the fence post is in the first position, it can restrict the outward displacement of the container; when the fence post rotates to the second position, it avoids the outward movement path of the container.

[0051] Fences come in a variety of shapes and sizes, which can be determined based on the structure of the container and its installation location. Please see below. Figure 3 and Figure 4 This paper illustrates four different types of fencing structures: a first positioning bracket 21, a second positioning bracket 22, a third positioning bracket 23, and a fourth positioning bracket 24. Each positioning bracket includes a fencing rod, but the structure of the fencing rod in each positioning bracket is not exactly the same. Taking the first positioning bracket 21 and the third positioning bracket 23 as examples, the first positioning bracket 21 includes a first fencing rod 211, and the third positioning bracket 23 includes a second fencing rod 231. Although the first fencing rod 211 and the second fencing rod 231 are both located outside the corresponding side container and have the same function, their structures are indeed different.

[0052] In one specific embodiment, some of the guardrails are further provided with bending rods, which further limit the position of the corresponding container in the vertical or height direction. For example, the second guardrail 231 of the third positioning bracket 23 is provided with bending rods 232 to further cooperate with the container to limit the position of the container. This can further improve the reliability of the container installation at the installation station and improve transportation safety.

[0053] In one specific example, the constraint component also includes a resilient pin that abuts against the fence post to limit the rotation angle of the fence post relative to the support body 2. This further improves the accuracy of the fence post's rotation into position and prevents vibration of the fence post during vehicle movement, thus enhancing transportation safety.

[0054] Specifically, the elastic pin may include a limiting pin 62, a spring 61, and a mounting frame 63. The mounting frame 63 is fixed to the bracket body 2, and the limiting pin 62 is mounted to the mounting frame 63 by the spring. The limiting pin 62 can reciprocate in the vertical direction, and the abutment part between the limiting pin 62 and the fence post is located outside the mounting frame 63. This method of positioning is simple and reliable, and occupies little space.

[0055] In the above embodiment, the locking component includes a locking pin 51, which is mounted on the bracket body 2 and can move horizontally relative to the bracket body 2. The fence post has a locking hole 5a. When the fence post is in the first position, the locking pin 51 can be inserted into the locking hole 5a to restrict the rotation of the fence post. Specifically, a fixed seat 52 can be provided on the bracket body 2, and the locking pin 51 is mounted on the fixed seat 52, allowing the locking pin 51 to move back and forth relative to the fixed seat 52.

[0056] In one specific embodiment, two bolts 53 are provided on the fence post, and a locking hole is formed between the two bolts 53. The locking pin and the locking hole restrict the fence post from rotating upward.

[0057] Of course, lock holes can also be directly installed on the fence post to engage with the locking pin 51.

[0058] The present invention has provided a detailed description of a vehicle for transporting fluid media. Specific examples have been used to illustrate the principles and implementation methods of the invention. The descriptions of these embodiments are merely illustrative and are intended to help understand the method and core ideas of the invention. It should be noted that those skilled in the art can make various improvements and modifications to the invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims.
