Description

Technical Field

[0001] This utility model belongs to the field of railway transportation technology, and in particular relates to a support device for railway transport containers. Background Technology

[0002] Railway transport containers are standardized freight units used for rail freight transport, characterized by high efficiency, convenience, and economy. Through standardized design and multimodal transport technology, goods can be quickly switched between rail, road, and waterway, achieving seamless logistics transportation. Containers are placed on support devices on the train's transport platform, with the four corner fittings of the container tightly connected to the support devices via rotary locking mechanisms to ensure stability during transport. However, due to the frequent vibrations and dynamic loads subjected to the support devices during long-term transport, these containers are prone to metal fatigue damage, leading to loosening or breakage of the rotary locking devices and ultimately causing container failure. Summary of the Invention

[0003] In view of this, the present invention aims to at least partially solve one of the related technical problems.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A support device for railway transport containers includes a support structure, two mounting structures, two positioning structures, four side tensioning devices, and multiple elastic locking devices.

[0006] The support structure is used to hold containers;

[0007] Two positioning structures are symmetrically arranged at the left and right ends of the support structure. Each positioning structure is connected to the support structure through multiple elastic locking devices. The positioning structure is used to limit and fix the container.

[0008] Four side tensioning devices are symmetrically arranged on the front and rear sides of the support structure. One end of the side tensioning device is connected to the support structure, and the other end of the side tensioning device is connected to the corner fitting of the container.

[0009] The two mounting structures are symmetrically arranged at the bottom of the support structure.

[0010] Furthermore, the support structure includes a support frame, two crossbeams and two longitudinal beams, which are staggered inside the support frame. The crossbeams and longitudinal beams are all fixedly connected to the support frame, and the support frame is connected to an elastic locking device and a side tensioning device.

[0011] Furthermore, the positioning structure includes a positioning plate, a first pressure plate, two support plates, and multiple stiffeners. The positioning plate has an L-shaped cross-section. The multiple stiffeners are arranged on the inner side of the positioning plate. The two support plates are symmetrically arranged at the front and rear ends of the positioning plate. The first pressure plate is located on the lower end face of the positioning plate. The first pressure plate is connected to the support frame through multiple elastic locking devices.

[0012] Furthermore, the elastic locking device includes a locking bolt, a first compression spring, and a stop plate. The locking bolt passes through the first pressure plate and is threadedly connected to the support frame. The first compression spring and the stop plate are both disposed on the locking bolt, and the stop plate is disposed between the countersunk head of the locking bolt and the first compression spring.

[0013] Furthermore, the side tensioning device includes a side pull plate, a fixing plate, a fixing seat, a second pressure plate, a fixing bolt, a locking nut, and a second compression spring. One end of the side pull plate is connected to the corner fitting of the container through the fixing plate, and the other end of the side pull plate is connected to the fixing bolt through the second pressure plate. The fixing bolt passes through the fixing seat and the second pressure plate. The locking nut is located at the tail of the fixing bolt. The second compression spring is located on the fixing bolt. One end of the fixing bolt abuts against the fixing seat, and the other end abuts against the second pressure plate. The fixing seat is fixedly connected to the support frame.

[0014] Furthermore, a buffer pad is provided on the inner side of the positioning plate.

[0015] Furthermore, the mounting structure is an L-shaped mounting plate, which is used to connect railway train transport plates, and multiple strip holes are arranged on the side of the mounting plate.

[0016] Compared with existing technologies, the support device for railway transport containers described in this utility model has the following advantages:

[0017] 1. The positioning structure employs a combination of positioning plates, a first pressure plate, and support plates. Through a symmetrical design, it achieves precise positioning and stable fixation of the container. This effectively prevents container displacement during transportation, improving transport safety. The L-shaped positioning plate enhances strength and stability. Its L-shaped cross-section provides excellent mechanical properties, allowing it to withstand significant vibration and dynamic loads, thus enhancing the structure's resistance to deformation. Multiple stiffening plates are arranged on the inner side of the positioning plate, increasing its overall rigidity and preventing deformation or damage due to excessive loads. A buffer pad is installed on the inner side of the positioning plate, providing elastic contact to absorb vibration and impact, reducing stress concentration caused by hard contact.

[0018] 2. The elastic locking device, through the elastic design of the compression spring and baffle, can adapt to displacement and slight movements caused by vibration, impact, or load changes during transportation. Even under complex transportation conditions (such as sudden stops, vibrations, or winding roads), it ensures locking effectiveness and prevents loosening or detachment. The first compression spring, through its elastic properties, absorbs vibrations and impacts generated during transportation, reducing the direct impact force from rigid connections. This reduces stress concentration at the connection points between the container corner fittings and the support device, protecting the device and container structure and extending their service life.

[0019] 3. The side tensioning device connects to the container's corner fittings via side tension plates and uses fixing bolts and compression springs to laterally tension the container. This effectively prevents lateral swaying or displacement of the container during transportation, enhancing safety and stability. A second compression spring is incorporated into the device, forming an elastic buffer structure between the side tension plate and the fixing seat, absorbing vibrations and impacts during rail transport. This reduces the impact of rigid contact between the container and the support structure, protecting the container corner fittings and support frame from excessive stress damage. Utilizing the compression spring and locking nut, the side tensioning device provides continuous preload, automatically compensating for any loosening caused by vibration or thermal expansion and contraction through spring rebound. The side tension plates are connected to the container corner fittings via fixing plates, evenly distributing the lateral tension across the container structure and preventing component damage due to concentrated stress.

[0031] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] A support device for railway transport containers, such as Figure 1 As shown, it includes a support structure 100, two mounting structures 501, two positioning structures 200, four side tensioning devices 400, and multiple elastic locking devices 300.

[0033] The support structure 100 is used to place the container; the support structure 100 includes a support frame, two crossbeams 102 and two longitudinal beams 101, the two crossbeams 102 and the two longitudinal beams 101 are staggered inside the support frame, the crossbeams 102 and the longitudinal beams 101 are welded to the support frame, and the support frame is connected to the elastic locking device 300 and the side tensioning device 400.

[0034] Two positioning structures 200 are symmetrically arranged at the left and right ends of the support structure 100. Each positioning structure 200 is connected to the support structure 100 through multiple elastic locking devices 300. The positioning structure 200 is used to limit and fix the container. The positioning structure 200 includes a positioning plate 201, a first pressure plate 203, two support plates, and multiple stiffening plates 202. The positioning plate 201 has an L-shaped cross-section. The multiple stiffening plates 202 are arranged on the inner side of the positioning plate 201. The two support plates are symmetrically arranged at the front and rear ends of the positioning plate 201. The first pressure plate 203 is located on the lower end face of the positioning plate 201 and is connected to the support frame through multiple elastic locking devices 300. A buffer pad is provided on the inner side of the positioning plate 201. The positioning structure 200 uses a combination of components such as the positioning plate 201, the first pressure plate 203, and the support plates. Through the symmetrical design of the structure, it achieves precise positioning and stable fixation of the container. This effectively prevents the container from shifting during transportation and improves transportation safety. The L-shaped positioning plate enhances strength and stability. The L-shaped cross-section of the positioning plate 201 provides excellent mechanical properties, enabling it to withstand significant vibration and dynamic loads, thus enhancing the structure's resistance to deformation. Multiple stiffening plates 202 are arranged on the inner side of the positioning plate 201, increasing its overall rigidity and preventing deformation or damage due to excessive loads. A buffer pad is installed on the inner side of the positioning plate 201, providing elastic contact to absorb vibration and impact forces, reducing stress concentration caused by hard contact.

[0035] The elastic locking device 300 includes a locking bolt 301, a first compression spring 303, and a stop plate 302. The locking bolt 301 passes through the first pressure plate 203 and is threadedly connected to the support frame. The first compression spring 303 and the stop plate 302 are both mounted on the locking bolt 301, with the stop plate 302 positioned between the countersunk head of the locking bolt 301 and the first compression spring 303. Through the elastic design of the compression spring and the stop plate 302, the elastic locking device 300 can adapt to displacement and micro-movements caused by vibration, impact, or load changes during transportation. Even under complex transportation conditions (such as sudden stops, vibrations, or curved driving), it ensures a locking effect and prevents loosening or detachment. The first compression spring 303, through its elastic properties, can absorb vibrations and impacts generated during transportation, reducing the direct impact force from rigid connections. This reduces stress concentration at the connection points between the container corner fittings and the support device, protecting the device and container structure and extending their service life.

[0036] Four side tensioning devices 400 are symmetrically arranged on the front and rear sides of the support structure 100. One end of the side tensioning device 400 is connected to the support structure 100, and the other end is connected to the corner fitting of the container. The side tensioning device 400 includes a side pull plate, a fixing plate, a fixing seat 401, a second pressure plate 404, a fixing bolt 402, a locking nut, and a second compression spring 403. One end of the side pull plate is connected to the corner fitting of the container through the fixing plate, and the other end of the side pull plate is connected to the fixing bolt 402 through the second pressure plate 404. The fixing bolt 402 passes through the fixing seat 401 and the second pressure plate 404. The locking nut is located at the tail of the fixing bolt 402. The second compression spring 403 is located on the fixing bolt 402. One end of the fixing bolt 402 abuts against the fixing seat 401 and the other end abuts against the second pressure plate 404. The fixing seat 401 is welded to the support frame. The side tensioning device 400 is connected to the container's corner fittings via a side tension plate and is laterally tensioned by fixing bolts 402 and a compression spring. This effectively prevents lateral swaying or displacement of the container during transportation, enhancing safety and stability. A second compression spring 403 is incorporated into the device, forming an elastic buffer structure between the side tension plate and the fixing seat 401, which absorbs vibrations and impacts during rail transport. This reduces the impact of rigid contact between the container and the support device, protecting the container corner fittings and support frame from excessive stress damage. Using the compression spring and locking nut, the side tensioning device 400 provides continuous preload, automatically compensating for any loosening caused by vibration or thermal expansion and contraction through spring rebound. The side tension plate is connected to the container corner fittings via a fixing plate, distributing the lateral tension evenly across the container structure and preventing component damage due to concentrated stress.
