Description

Technical Field

[0001] This utility model relates to the field of container transportation technology, and in particular to a container limiting frame. Background Technology

[0002] With the rapid development of the railway transportation industry, in order to meet the special requirements of coke transportation, the railway department has developed special coke transport vehicles. Compared with ordinary railway freight cars, the length, height, and width of the coke-specific cars are larger than those of ordinary freight cars.

[0003] A 20-foot container is approximately 6 meters long and 2.55 meters wide. A typical railway open wagon is approximately 12.5-13 meters long and 2.9 meters wide. When two containers are loaded into one wagon, their length and width match in both directions. However, in railway freight practice, to improve transport efficiency, coke-specific wagons are sometimes used to transport containers. These coke-specific wagons are approximately 14.59 meters long and 2.95 meters wide. The length and width of two containers loaded into these wagons are much smaller than the dimensions of the coke-specific wagons, resulting in a significant space mismatch. Specifically, there is a gap between the two containers along the transport direction, and also gaps between the containers and the wagon walls on both sides. This space mismatch, especially during operation at sections requiring speed adjustments such as side stations, can cause relative displacement and collisions between the containers and between the containers and the wagon walls due to the inertial forces generated by braking. Such collisions can not only damage goods and transport equipment but also potentially lead to operational safety accidents, threatening the reliability and safety of railway transport. Utility Model Content

[0004] The purpose of this utility model is to provide a container limiting frame that can prevent collisions between two containers and reduce the impact between the container and the inner wall of the carriage, thereby ensuring the reliability and safety of railway transportation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a container limiting frame, including a base and a limiting component.

[0023] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0024] This embodiment provides a container limiting frame, such as Figure 1 and Figure 2As shown, the device includes a base 1 and a limiting component 2. The base 1 is used to be positioned between two containers 3 arranged along the X direction. Both ends of the base 1 along the X direction have a first limiting surface 111, which is used to limit the position of the container 3 relative to the carriage 4 along the X direction. Both ends of the base 1 along the X direction are connected to the limiting component 2, which has a second limiting surface 21, which is used to limit the position of the container 3 relative to the carriage 4 along the Y direction. The Y direction is perpendicular to the X direction, and both the X and Y directions are parallel to the horizontal plane.

[0025] When using, such as Figure 2 As shown, the container limiting frame provided in the above embodiment can be installed between two containers 3 arranged along the X direction. During transportation, the first limiting surface 111 at one end of the base 1 along the X direction can limit the X-direction position of one container 3 relative to the carriage 4, and the second limiting surface 21 of the limiting component 2 at that end of the base 1 can limit the Y-direction position of the container 3 relative to the carriage 4; the first limiting surface 111 at the other end of the base along the X direction can limit the X-direction position of the other container 3 relative to the carriage 4, and the second limiting surface 21 of the limiting component 2 at that end of the base 1 can limit the Y-direction position of the container 3 relative to the carriage 4, thereby achieving the limiting of the two containers 3.

[0026] Compared with the prior art, the container limiting frame provided in this embodiment can limit the X and Y positions of the containers 3 on both sides relative to the carriage 4, effectively reducing the swaying amplitude of the containers 3 during the adjustment of the transport vehicle speed, avoiding collisions between the two containers 3, and reducing the collisions between the containers 3 and the inner wall of the carriage 4, thus ensuring the reliability and safety of railway transportation.

[0027] In alternative implementations, such as Figure 1 As shown, the limiting component 2 includes a first limiting seat 22 and a second limiting seat 23, both of which are connected to the base 1. The first limiting seat 22 and the second limiting seat 23 are arranged opposite to each other along the Y direction, and the surfaces of the first limiting seat 22 and the second limiting seat 23 that are arranged opposite to each other are provided with a second limiting surface 21.

[0028] When the container limiting frame is placed between two containers 3, the limiting components 2 located at both ends of the base 1 limit the Y-direction position of the adjacent containers 3 respectively. Specifically, the first limiting seat 22 and the second limiting seat 23 in each limiting component 2 contact the sides of the container 3 through their oppositely arranged second limiting surfaces 21, thereby reducing the container's deviation or swaying along the Y-direction during transportation and improving the stability and safety during transportation.

[0029] The above-described implementation not only achieves effective positioning of container 3 in the Y direction, but also ensures the centering of container 3 through a double-sided positioning structure. That is, compared with single-sided positioning, it can ensure that container 3 is basically located in the middle of the carriage 4 along the Y direction, avoiding the problem of installation offset of container along the Y direction, and further improving the safety and stability of container transportation.

[0030] The first limiting seat 22 and the second limiting seat 23 can be fixedly connected to the base 1 by means of bolts, welding or integral molding to ensure that they have sufficient structural strength and stability during transportation.

[0031] Specifically, the first limiting seat 22 and the second limiting seat 23 can be welded together from multiple metal plates to form a protruding structure protruding from the surface of the base 1 in a vertically upward direction.

[0032] The aforementioned second limiting surface 21 can extend in the vertical direction or form a certain angle with the vertical direction.

[0033] In an optional embodiment, the distance between the second limiting surfaces 21 on the first limiting seat 22 and the second limiting seat 23 gradually increases in the vertically upward direction, so as to guide the container 3 when it is hoisted from top to bottom into the carriage 4.

[0034] During the lowering of container 3, as the bottom of container 3 approaches the container positioning frame, its two sides first contact the two second positioning surfaces 21. Since the distance between the second positioning surfaces 21 gradually decreases from top to bottom, container 3 automatically aligns with the center under the guidance of gravity and the second positioning surfaces 21, ensuring it lands in the middle of the carriage 4 along the Y-axis. This not only improves the alignment and safety of container 3 during hoisting but also effectively reduces the workload of manual adjustments and increases loading and unloading efficiency.

[0035] In an optional embodiment, the base 1 includes a frame 11 and a guide assembly 12. The frame 11 has guide assemblies 12 connected to both ends along the X-direction. Each guide assembly 12 has a guide surface 121 located vertically above the first limiting surface 111, meaning that the guide surface 121 is higher than the first limiting surface 111 in the vertical direction. The guide surface 121 is designed as an inclined or curved surface so that if there is a certain deviation in the falling position of the container 3 during its descent, the guide surface 121 can guide the container 3 to the correct position through its inclined or curved structure, ensuring smooth contact with the first limiting surface 111.

[0036] In practice, when container 3 is hoisted from top to bottom into the carriage 4 by the hoisting equipment, the bottom of container 3 first contacts the guide surface 121 of the guide assembly 12. Since the guide surface 121 is located above the first limiting surface 111 and has a certain angle or curvature, container 3 slides along the guide surface 121 under gravity, gradually moving towards the side of the base 1 until the side of container 3 contacts the first limiting surface 111 and is positioned. This guiding process effectively reduces the workload of manually adjusting the position of container 3, improves hoisting efficiency, and avoids impacts or uneven loading caused by inaccurate positioning.

[0037] In alternative implementations, such as Figure 1 As shown, the guide assembly 12 includes a first guide seat 122 and a second guide seat 123. The first guide seat 122 and the second guide seat 123 are arranged opposite to each other along the Y direction, and the sides of the first guide seat 122 and the second guide seat 123 facing the X direction are provided with guide surfaces 121.

[0038] The above-described embodiment, by setting up a symmetrically arranged first guide seat 122 and second guide seat 123, and setting a guide surface 121 on the X-direction side of the guide seat, realizes the automatic centering function of the container 3 during the installation process, improves the positioning accuracy and operation convenience of the container limit frame, and further enhances the stability and safety during transportation.

[0039] Specifically, the first guide seat 122 and the second guide seat 123 have the same structure, both of which can be welded from multiple metal plates, and have good structural strength and wear resistance.

[0040] The first guide seat 122 and the second guide seat 123 can be fixedly connected to the frame 11 of the base 1 by bolts or welding, which facilitates disassembly, replacement and maintenance.

[0041] In an optional embodiment, the guide surface 121 is inclined toward the center of the frame 11 in a vertically upward direction.

[0042] The aforementioned middle section can be understood as the frame 11 being parallel to the central symmetry plane in the Y direction, that is, the guide surface 121 is inclined towards the aforementioned central symmetry plane in the vertical upward direction, so that the two guide surfaces 121 arranged opposite to each other in the X direction are arranged in an inverted "V" shape or "eight" shape in space.

[0043] In alternative implementations, such as Figure 1 and Figure 3As shown, the frame 11 includes two longitudinal beams 112, two transverse beams 113, and two connecting plates 114; the two longitudinal beams 112 are arranged opposite each other along the Y direction and extend along the X direction; the two transverse beams 113 are arranged opposite each other along the X direction and extend along the Y direction, and the two transverse beams 113 and the two longitudinal beams 112 are connected to form a rectangular frame structure; each transverse beam 113 is connected to a connecting plate 114, and the connecting plate 114 extends outward along the X direction from the transverse beam 113, and the limiting component 2 is connected to the top surface of the connecting plate 114.

[0044] In addition, the first limiting seat 22 and the second limiting seat 23 are both connected to the two crossbeams 113, and the first limiting seat 22 and the second limiting seat 23 are respectively connected to the adjacent longitudinal beams 112 with reinforcing ribs.

[0045] like Figure 1 As shown, a reinforcing corner tube 115 is connected between the crossbeam 113 and the longitudinal beam 112. The reinforcing corner tube 115 can increase the ability of the crossbeam 113 and the longitudinal beam 112 to resist deformation and strengthen the structural strength of the frame 11.

[0046] Both the crossbeam 113 and the longitudinal beam 112 can be made of hollow square steel.

[0047] To reduce the weight of the connecting plate 114 and enhance its strength, multiple through holes may be provided on the connecting plate 114.

[0048] In alternative implementations, such as Figure 3 As shown, the container limiting frame also includes a retaining beam 5. The base 1 is connected to retaining beams 5 on both sides that are opposite to each other along the Y direction. The retaining beams 5 are used to cooperate with the inner wall of the carriage 4 to limit the position of the base 1 relative to the carriage 4 along the X direction.

[0049] like Figure 4 and Figure 5 As shown, the retaining beam 5 can be a rigid structure, such as welded metal profiles or integrally formed on the base 1. The inner wall of the carriage 4 is provided with multiple protruding structures 41, which are spaced apart along the X-direction. The retaining beam 5 can be confined between two adjacent protruding structures 41. When the container retaining frame is placed in the carriage 4, the degree of freedom of the retaining beam 5 along the X-direction is restricted by the two protruding structures 41, thereby enhancing the stability of the container retaining frame in the carriage 4.

[0050] Reference Figure 5 As shown, a limiting component 2 may be provided on the side of the protruding structure 41 that is away from the blocking beam 5.

[0051] In alternative implementations, such as Figure 1 and Figure 6As shown, the container limiting frame also includes a stacking positioning seat 6 connected to the base 1. The stacking positioning seat 6 has an insertion slot 61 with a downward opening 611 in the vertical direction. The width of the insertion slot 61 gradually decreases in the vertical upward direction to facilitate the stacking of the base 1.

[0052] When container limit racks are not needed, they can be stacked vertically. In this case, the stacking positioning seat 6 of the lower container limit rack can be inserted into the upper stacking positioning seat 6 through the lower opening 611 of the upper container limit rack, so as to achieve tight stacking of each layer of container limit racks.

[0053] Specifically, to facilitate the processing of the aforementioned stacking positioning seat 6, the stacking positioning seat 6 can be bent from a plate into a semi-enclosed structure, and the stacking positioning seat 6 can be welded or fixed to the reinforcing corner tube 115 through other connection methods.

[0054] In an optional embodiment, the container limiting frame also includes a locator 7 connected to the base 1, the locator 7 being used to monitor the position of the container limiting frame.

[0055] The aforementioned locator 7 can integrate multi-mode fusion positioning technology, including Global Positioning System (GPS), cellular network positioning (LBS), and wireless local area network positioning (Wi-Fi), and achieve high-precision, all-weather positioning of the container limiter and the container 3 it limits through multi-source data fusion algorithms.

[0056] Specifically, the locator 7 is connected to the inside of the frame 11 and is fixed to the frame 11 by screws or clips, and is electrically connected to the power module and communication module on the frame 11. The locator 7 can collect key parameters during transportation, such as the geographical location information, movement trajectory data, moving speed, direction angle, and dwell status of the container limit frame, in real time.

[0057] In addition, the locator 7 can also upload the collected data to the cloud management platform in real time through the wireless communication module. The cloud management platform processes, analyzes and visualizes the received data, enabling the carrier to view the cargo's transportation location, driving trajectory, estimated arrival time and other information in real time through terminal devices (such as PCs, tablets or mobile phones).

[0058] When the container limiter and the container 3 it limits experience abnormal stops, path deviations, or speeding, the system can automatically trigger an early warning mechanism and notify relevant personnel via SMS or APP, so that timely countermeasures can be taken to reduce transportation risks.

[0059] In alternative implementations, such as Figure 1As shown, the container limiting frame also includes a hook 8 connected to the base 1. The hook 8 is used to realize the detachable connection between the limiting frame and the lifting equipment, thereby facilitating the installation of the container limiting frame before use and the disassembly and handling after use.

[0060] Specifically, multiple hooks 8 are configured and connected to the inside of the frame 11, and are fixedly connected to the frame 11 by screws or clips.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
