Description

Technical Field

[0001] The invention relates to a container, in particular to a tank container capable of being loaded and unloaded at both sides. Background Art

[0002] At present, the transportation of liquid, gas and powdery solid goods is mainly carried out through three modes: railway transportation, road transportation and combined road-rail transportation.

[0003] For rail transport, rail tank cars are mainly used for transportation. However, it has the problems of high fixed costs and large initial investment, and is difficult to organize and takes a long time. In addition, it is impossible to achieve "door-to-door" transportation, and the corresponding ground facilities and matching issues are complicated. Therefore, rail tank car transportation is not economical for short-distance transportation.

[0004] For road transportation, road tankers are mainly used for transportation. However, they have the problems of high energy consumption, many safety hazards, large land occupation, and serious impact from weather. At the same time, the transportation capacity is small. Therefore, road tanker transportation is not economical for long-distance transportation.

[0005] For road-rail transport, tank containers + railway flat cars are generally used for transportation. The method of tank containers + railway dedicated or shared flat cars can better solve the shortcomings of the above two methods and effectively improve the economic efficiency of transportation, but it has higher requirements for tank containers.

[0006] At present, the industry mostly uses tank containers that are unloaded from below. Due to their structural characteristics, the unloading ports of tank containers are all set at the rear end; but this position is also equipped with a door stop structure, which is a device used to prevent the container from sliding. When the tank container falls on the railway flat car, the unloading port will be blocked by the door stop, making it impossible to complete loading and unloading. Therefore, even if there are dedicated lines and loading and unloading positions at both ends of the tank container, it is necessary to unload it from the railway flat car first, and then transfer it before completing loading and unloading. This leads to complex freight organization, excessive energy and manpower consumption, and poor economic efficiency.

[0007] Chinese patent CN117302783A discloses a large-volume liquid tank container that can be interconnected, including a plurality of storage tank assemblies, each storage tank assembly including a frame body and a tank body fixed in the frame body for storing liquid; a loading and unloading pipeline system, each tank body is provided with a loading and unloading pipeline system for controlling the on-off of the loading and unloading oil circuit in the tank body; and a transmission component, each tank body is provided with a transmission component to connect two adjacent tank bodies, and when the loading and unloading pipeline system on any tank body is working, it can drive other tank bodies to carry out loading and unloading work at the same time.

[0008] The tank container has an opening at the lower side beam to avoid interference, but only provides a single-side unloading method. Ground loading and unloading points usually have a single or a row of loading and unloading ports, which requires the shipping vehicle to dock accurately at the tank container loading and unloading side. This is feasible for road vehicles, but for railway flat cars that are loaded and unloaded in a row, the freight organization is complex and the cost is high, which still cannot solve the above problem. Therefore, this method is difficult to meet the needs of tank containers in road, rail and water transport. Summary of the invention

[0063] The specific technical solutions in the embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0064] Compared with the existing transportation equipment for transporting liquid, gas and powdered solid goods, the present invention combines the characteristics and requirements of railway and road transportation and loading and unloading, and designs a tank container with a two-side loading and unloading solution. It is suitable for the transportation and loading and unloading needs of railway dedicated or shared flat cars, without the need to use road flat cars for reverse transportation and loading and unloading, which reduces the difficulty of freight organization, reduces energy and manpower consumption, and thus improves the product economy.

[0065] Technical idea: To solve the loading and unloading problem, a two-side loading and unloading solution is designed to achieve direct loading and unloading of goods on the railway dedicated line without transferring tank containers; setting loading and unloading joints on both sides will limit the bottom space, so the tank body is raised relative to the frame; the elevation needs to meet the structural strength of the frame, so a full-size frame is used; the full-size frame will have interference problems between the loading and unloading joints on both sides and the bottom of the frame, so the lower side beam is opened and partially reinforced. In addition, after the tank body is raised relative to the frame, the tank body volume will be reduced due to the overall size requirements, so a tank body with a square round cross-section and a high box frame are used to increase the tank body volume.

[0066] At the same time, while taking into account the optimal technical parameters of existing tank containers, the tank container is equipped with safety loading and unloading accessories such as overflow protection system, pneumatic control system and oil and gas recovery system. On the basis of improving the safety of the tank container, the pneumatic control system is used to simplify the workers' operating procedures, and the oil and gas recovery system is used to alleviate environmental pollution problems.

[0067] See also Figure 1 An embodiment of the present invention provides a tank container for loading and unloading on both sides, including a frame assembly 100, a tank assembly 200 arranged in the frame assembly 100, and a walkway assembly 300 arranged on the frame assembly 100.

[0068] Definition: The end of the tank assembly 200 facing the transport direction is the front end, and the other end is the rear end. The horizontal height of the front end is greater than the horizontal height of the rear end, and the height difference is greater than 10mm to ensure the clean unloading rate of the medium.

[0069] refer to Figure 2 The frame assembly 100 adopts the specifications of a high box frame, including two parallel end frames 110, two upper beams 101 and two lower beam assemblies 120 connecting the two end frames 110; a diagonal brace 102 is arranged between the end frame 110 and the upper beam 101. Each component is welded.

[0070] The tank assembly 200 includes a cylinder 203 and two seals 201 disposed at both ends of the cylinder 203 . The cylinder 203 and the seals 201 form a cavity for storing goods to be transported.

[0071] A bolt-mounted and detachable end ladder 103 is provided on the end frame 110 at the front end; the walkway assembly 300 is an I-shaped walkway spliced ​​with multiple walkways, and its edges are respectively connected to the two upper beams 101 to improve the structural strength of the upper beams 101.

[0072] The axial cross section of the cylinder 203 is a square circle; skirt seats 202 are also provided on the outer periphery of both ends of the cylinder 203 , and the frame assembly 100 and the tank assembly 200 are connected via the skirt seats 202 .

[0073] refer to Figure 5 A manhole 210, a safety valve 220, an overflow protection device 230 and a filling metering device 240 connected to the cavity are provided above the cylinder 203, and a bottom loading and unloading device 250, a pneumatic control system 260 and an oil and gas recovery system 270 are provided below; the positions of the manhole 210 and the end ladder 103 correspond to the walkway assembly 300; the overflow protection device 230 and the filling metering device 240 are connected to the pneumatic control system 260.

[0074] The function of the safety valve 220 is to protect the cylinder 203 and keep the cavity pressure within the designed pressure range; the overflow protection device 230 automatically cuts off the filling system when the filling of goods is abnormal, such as when the liquid level exceeds the limit value, to avoid tank overflow; the filling metering device 240 is reserved with a top filling port and a liquid level metering port; the pneumatic control system 260 remotely sequentially operates the oil and gas recovery system 270 and the bottom loading and unloading system 250 through the control panel to perform loading and unloading operations, so as to improve the safety and convenience of the tank container. While balancing the cavity loading and unloading pressure, the oil and gas recovery system 270 effectively recovers the oil and gas in the atmospheric space of the tank, preventing the oil and gas from being discharged to pollute the environment while improving the economic efficiency.

[0075] The bottom loading and unloading device 250 includes two loading and unloading joints respectively arranged on both sides of the cylinder 203, and the loading and unloading joints are connected to the bottom of the cavity through loading and unloading pipes; the bottom loading and unloading device 250 is arranged below the cylinder 203 near the rear end, and the two loading and unloading joints are located in corresponding positions relative to the cylinder 203. The loading and unloading pipe includes two segmented loading and unloading pipes, which are respectively arranged on both sides below the cylinder 203, one end of the segmented loading and unloading pipe is connected to the corresponding bottom valve of the cylinder 203, and the other end is connected to the two loading and unloading joints respectively.

[0076] The oil and gas recovery system 270 includes two oil and gas recovery joints respectively arranged on both sides of the cylinder 203, and the oil and gas recovery joints are connected to the top of the cavity through the oil and gas recovery pipeline. The oil and gas recovery pipeline includes an inner section pipeline and an outer section pipeline. The inner section pipeline is arranged inside the cylinder 203, one end of which is connected to the top valve of the cylinder 203, and the other end extends out of the cylinder 203 and is connected to the middle part of the outer section pipeline arranged below the cylinder 203; the two ends of the outer section pipeline are respectively connected to the two oil and gas recovery joints. The inner section pipeline of the oil and gas recovery pipeline is a bow-shaped pipeline, which is arranged along the inner wall of the cavity; the outer section pipeline of the oil and gas recovery pipeline is bent upward near the two ends and extends between the lower beam 121 and the lower reinforcement beam; at least two annular plate-type reinforcing ribs are arranged in parallel along the circumference of the cylinder 203 inside the cavity.

[0077] The inner section of the oil and gas recovery pipeline is set inside the cylinder 203. First, the external space is limited and the pipeline cannot be placed. If the pipeline is placed, the volume of the tank will inevitably be reduced, which will reduce the economic efficiency of the tank box; second, the durability of the pipeline outside the tank is not as good as that inside the tank, and there is a risk of external damage and corrosion. In addition, the tank body often deforms during transportation. In order to adapt to the deformation, refer to Figure 7 The inner section of the pipeline is designed as a bow-shaped pipeline to avoid weld fatigue cracking at the joints at both ends of the pipeline.

[0078] The pneumatic control system 260 is respectively connected to the bottom loading and unloading device 250 and the oil and gas recovery system 270 by air circuits to control the opening and closing of the loading and unloading pipeline and the oil and gas recovery pipeline.

[0079] refer to Figure 3 The lower beam assembly 120 includes a lower beam 121 and a lower reinforcement beam; the lower reinforcement beam includes an oblique beam 122, a longitudinal beam 123 and two longitudinal beam supports 124.

[0080] One end of the oblique beam 122 is connected to the lower beam 121, and the other end is connected to one end of the longitudinal beam 123; the other end of the longitudinal beam 123 is connected to the end frame 110; the angle between the oblique beam 122 and the lower beam 121 is less than 45° to meet the strength and bending resistance requirements of the lower beam when it is subjected to longitudinal impact; the longitudinal beam 123 and the lower beam 121 are connected through the longitudinal beam support 124, and the two longitudinal beam supports 124 are respectively arranged on both sides of the loading and unloading groove; the pneumatic control system 260 and the oil and gas recovery joint are arranged between the oblique beam 122, the longitudinal beam 123, the longitudinal beam support 124 and the lower beam 121.

[0081] The two lower side beams 121 are each provided with loading and unloading grooves corresponding to the positions of the two loading and unloading joints; the lower side reinforcement beam is arranged above the loading and unloading grooves, and the lower side surface of the lower side beam 121 located at the loading and unloading groove position and the surface of the loading and unloading groove are both provided with reinforcement structures, which are used to increase the structural strength of the loading and unloading grooves, ensure the continuity of the structure as well as the strength and rigidity requirements, and ensure the structural safety of the tank container when subjected to longitudinal impact.

[0082] The reinforcement structure includes a first groove reinforcement plate 125 and a second groove reinforcement plate 126. The first groove reinforcement plate 125 is located on the surface of the loading and unloading groove, and the second groove reinforcement plate 126 is arranged on the lower side of the lower side beam 121 located at the loading and unloading groove position.

[0083] The first groove reinforcement plate 125 fits the loading and unloading groove, and the outward extension length of both ends thereof is greater than 50 mm to meet the welding position requirements.

[0084] refer to Figure 8 The axial center line of the longitudinal beam 123 and the regional center axial position of the reinforcement structure (i.e., the middle position of the first groove reinforcement plate 125 and the second groove reinforcement plate 126) are symmetrical about the center of the inscribed circle of the loading and unloading groove; the center of the circle is respectively connected with the two upper edges of the groove walls of the loading and unloading groove, and the extended lines of the two connecting lines intersect with the bottom edge of the lower side beam 121 respectively to form two intersection points. The length of the second groove reinforcement plate 126 is greater than the distance between the two intersection points, thereby compensating for the strength and stiffness loss at the opening to the greatest extent.

[0085] refer to Figure 4 The end frame 110 is provided with two upper diagonal braces 131 at the two corners on the upper side, and two lower diagonal brace assemblies at the two corners on the lower side; the two lower diagonal brace assemblies are connected by a lower side reinforcing plate 132, and the lower side reinforcing plate 132 is connected to the skirt 202.

[0086] The upper oblique support 131 is a triangular reinforcement plate; the upper edge of the lower reinforcement plate 132 is an arc-shaped transition line; while utilizing the stability of the triangle, the skirt 202 falls on the upper oblique support 131; after the tank body is raised, the skirt 202 cannot be completely and directly connected to the end frame 110, and is therefore connected to the lower reinforcement plate 132, making the transmission of longitudinal force more direct.

[0087] The lower diagonal brace assembly includes a lower diagonal brace 133 and a small diagonal brace 134 which is arranged parallel to the lower diagonal brace and has a gap therebetween; the two lower diagonal braces 133 are connected by a lower side reinforcing plate 132; avoidance grooves 135 are provided at the lower side of the end frame 110 and at positions corresponding to the two small diagonal braces 134, and reinforcing plates are provided in the avoidance grooves 135. The width of the avoidance grooves 135 is greater than the width of the standard corner fittings to solve the problem that the stacking of tank containers is offset and difficult to find, that is, the avoidance grooves 135 are used to magnify the degree of skewness of the tank containers stacked between each other, and when the tank containers are stacked incorrectly, the operator is reminded that the tank containers are not stacked correctly.

[0088] In other embodiments of the present invention, the siphon principle can be used to suck the liquid cargo out of the loading and unloading pipeline when unloading the vehicle, as shown in FIG. Figure 6 The loading and unloading pipeline is arranged at the lower part of the cylinder 203, and a siphon pipe connected to the cavity is opened downward in the middle, and the two ends extend out of the cylinder 203 and bend downward, and are connected to two loading and unloading joints. In this way, the volume of the tank can be increased to a greater extent, and the medium unloading rate can be improved.
