Description

Technical Field

[0001] This utility model relates to the field of railway freight car technology, specifically to a railway freight car and a railway freight car. Background Technology

[0002] In recent years, with the continuous growth in demand for railway container transportation, general-purpose railway freight cars have been widely used for container transport tasks due to their wide applicability. However, since these vehicles were primarily designed for bulk cargo such as coal, ore, and steel, their structure was not specifically optimized for the loading characteristics of containers. This has led to a series of structural strength deficiencies during actual transportation, such as floor deformation and cracking of small crossbeam welds. This not only poses a threat to transportation safety but also significantly increases vehicle maintenance costs.

[0003] However, existing general-purpose railway freight cars typically do not employ reinforcement measures between containers or between containers and cars when loading containers. The containers are simply placed directly on the car floor. This loading method results in significant gaps between the container and the car body, making the container prone to shifting during transport. This can lead to collisions between the container and the vehicle structure, and even induce the risk of uneven loading. Furthermore, during hoisting operations, uneven cargo distribution or operational factors causing container swaying can also damage the railway freight car structure or the container itself.

[0004] Therefore, there is an urgent need for a railway freight car and a railway freight car to solve the above-mentioned technical problems. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] Firstly, see Figures 1-3 This application provides an embodiment of a railway freight car and a railway freight car. The railway freight car includes a car body and a guiding and positioning mechanism 4. The car body includes two side plates 2, two end plates 3, and a bottom plate 1. The two side plates 2 are fixed to both ends of the bottom plate 1 along the width direction, and the two end plates 3 are fixed to both ends of the bottom plate 1 along the length direction. The bottom plate 1, the two side plates 2, and the two end plates 3 enclose a receiving cavity for placing a container. There are multiple guiding and positioning mechanisms 4. Each guiding and positioning mechanism 4 includes a support seat 41 and a guide seat 42. The support seat 41 and the guide seat 42 are located in the receiving cavity. Multiple support seats 41 are respectively fixed on the side plates 2 and the end plates 3. The guide seat 42 is rotatably connected to the support seats 41. The guide seat 42 can guide and position the container. Multiple guiding and positioning mechanisms 4 are respectively fixed on the side plates 2 and the end plates 3. The railway freight car provided in this embodiment provides precise guidance and stable positioning for containers by setting a guide positioning mechanism 4 with a rotatable guide seat 42 on the side plate 2 and end plate 3. This effectively limits the lateral and longitudinal movement of containers during railway transportation, significantly reduces the risk of collision between containers and the inner wall of the car, prevents deformation of the car body structure and damage to the container, effectively eliminates the problem of off-center loading caused by container displacement, improves the safety and stability of cargo transportation, and can adapt to the transportation needs of containers of different specifications, thus improving the versatility and utilization efficiency of the vehicle. like Figures 1-3 As shown, in some embodiments, the guide seat 42 includes a guide portion 421 and a positioning portion 422. The guide portion 421 is inclined along the height direction. The guide seat 42 can rotate relative to the support seat 41 to switch between a guide position and a positioning position. When the guide seat 42 rotates to the guide position, the container can move along the guide portion 421 into the receiving cavity. When the guide seat 42 rotates to the positioning position, the container can abut against the positioning portion 422.

[0025] By combining the inclined guide part 421 with the positioning part 422 for limiting, and the guide seat 42 being rotatable around the support seat 41, flexible switching between the guiding position and the positioning position can be achieved. When the guide seat 42 is in the guiding position, its inclined guide part 421 can effectively guide the container to slide smoothly and accurately into the accommodating cavity during the hoisting process, thereby significantly reducing the risk of collision between the container and the vehicle body, and improving loading efficiency and operational safety. When the guide seat 42 is switched to the positioning position, the container and the positioning part 422 are firmly abutted, forming reliable longitudinal and lateral constraints, effectively preventing safety hazards such as uneven loading and container collision damage caused by container movement during transportation. Thus, while ensuring transportation safety, the reliability and economy of general open wagons adapted to container transportation are improved.

[0026] like Figures 1-3 As shown, in some embodiments, the support base 41 is fixedly provided with a stop block 411, and when the guide base 42 rotates to the positioning position, the guide base 42 can abut against the stop block 411.

[0027] By setting a stop block 411 fixed to the support base 41, the guide seat 42 can achieve precise limiting and stable support when it rotates to the positioning position. When the guide seat 42 rotates to the working position, it reliably abuts against the stop block 411 to form a firm mechanical limit, effectively preventing the guide seat 42 from over-rotating and shaking under the load of the container or the vibration of the vehicle, ensuring that the positioning part 422 always maintains a preset contact state with the container, thereby providing a continuous and stable constraint force for the container and ensuring the positioning reliability and structural safety during transportation.

[0028] like Figures 1-3 As shown, in some embodiments, the guide positioning mechanism 4 further includes a connecting component, which includes a rotating shaft 43 and an elastic element. The guide seat 42 is rotatably connected to the support seat 41 through the rotating shaft 43. The elastic element is sleeved on the rotating shaft 43. One end of the elastic element acts on the support seat 41, and the other end of the elastic element acts on the guide seat 42. The elastic element can drive the guide seat 42 to rotate to the initial position.

[0029] By setting up a connecting assembly including a rotating shaft 43 and an elastic element sleeved on it, the guide seat 42 can automatically reset after being deflected by force. The elastic element provides a continuous restoring torque to the guide seat 42 through its elastic force acting on the support seat 41 and the two ends of the guide seat 42. This allows the guide seat 42 to automatically and reliably return to its initial preset position after the container is not positioned or guided or after an accidental collision. This ensures that the guiding device is always in a ready-to-operate state, effectively improving the continuity and reliability of equipment use, while reducing manual intervention and lowering the intensity of operation.

[0030] like Figures 1-3As shown, in some embodiments, the guide seat 42 is provided with a groove 423, and the rotating shaft 43 passes through the groove 423.

[0031] By inserting the rotating shaft 43 into the groove 423 of the guide seat 42, the guide seat 42 can achieve both rotational guidance and vertical elastic buffering capabilities. When the container generates vertical impact loads during loading, unloading, or transportation, the guide seat 42 can slide slightly relative to the rotating shaft 43 along the groove 423, thereby effectively absorbing and dispersing instantaneous impact energy, avoiding damage to the vehicle structure and container body caused by rigid collisions, and thus significantly improving the adaptability and durability of the guide positioning mechanism 4 under complex working conditions.

[0032] like Figures 1-3 As shown, in some embodiments, a drive mechanism is also included. Multiple drive mechanisms are provided, and the multiple drive mechanisms are respectively fixed between the guide positioning mechanism 4 and the side plate 2 and between the guide positioning mechanism 4 and the end plate 3. The drive mechanism can drive the guide positioning mechanism 4 away from or close to the container.

[0033] By setting up multiple drive mechanisms that are respectively connected between the guide positioning mechanism 4 and the side plate 2 and end plate 3, the lateral position of the guide positioning mechanism 4 can be automatically and precisely adjusted. The drive mechanism can actively drive all guide seats 42 to move away from or closer to the container simultaneously according to the size specifications of different types of containers, thereby ensuring that the guide seats 42 and the container body form the best fit clearance, effectively eliminating the risk of off-center loading caused by manufacturing tolerances or differences in container size, and significantly improving loading adaptability, operational automation level and transportation safety.

[0034] like Figures 1-3 As shown, in some embodiments, the drive mechanism includes a drive member and a push rod. Multiple drive members are fixed on the side plate 2 and the end plate 3 respectively. The output end of the drive member is fixed with a push rod, and the other end of the push rod is fixed to the support base 41. The drive member can drive the push rod to move the support base 41 away from or closer to the container.

[0035] The drive mechanism, consisting of a drive component and a push rod, enables automatic control of the lateral position of the support seat 41 and the entire guide positioning mechanism 4. The linear thrust output by the drive component is precisely transmitted to the support seat 41 through the push rod, allowing it to move stably and reliably away from or close to the container according to operational needs. This precisely adjusts the contact distance between the guide seat 42 and the container, ensuring adaptability and positioning reliability for containers of different specifications, and effectively improving loading efficiency and automation level.

[0036] like Figures 1-3As shown, in some embodiments, a control unit is included, and a pressure sensor is provided on the side of the guide seat 42 that contacts the container. The control unit can control the drive member to drive the push rod to move the support seat 41 away from or towards the container based on the pressure detected by the pressure sensor.

[0037] By setting up pressure sensors and control units, intelligent control of the contact pressure between the guide seat 42 and the container is achieved. The pressure sensor can monitor the force state of the guide surface in real time. When the pressure exceeds the preset safety range, the control unit immediately drives the push rod to adjust the position of the support seat 41 and dynamically adjust the contact distance. This ensures effective positioning while completely eliminating damage to the container or vehicle structure caused by overpressure, achieving adaptive flexible guidance and overload protection, and comprehensively improving the system's intelligence level and operational reliability.

[0038] like Figures 1-3 As shown, in some embodiments, a cushioning pad is provided on the side of the guide seat 42 that contacts the container.

[0039] By setting a buffer pad on the side of the guide seat 42 that contacts the container, the contact impact energy is effectively absorbed and the vibration noise is significantly suppressed. The buffer pad can greatly reduce the instantaneous collision force between the container and the guide seat 42 during the guiding and positioning process, avoid the scratches and deformations caused by rigid contact to the container surface and the guiding mechanism, and reduce operating noise. While ensuring positioning accuracy, it can effectively improve the stability of equipment operation and service life.

[0040] Secondly, an embodiment of this application provides a railway freight car, including the railway freight car as described above, and also including a frame, with a bottom plate 1 fixed to the frame.

[0041] The railway freight car provided in this embodiment optimizes the stress distribution of the entire vehicle structure by securely mounting the freight car with a guide positioning mechanism 4 onto the frame. While retaining the general bulk cargo transportation capacity, the freight car effectively solves the technical problems of container movement, off-center loading, and collision with the car body during transportation. This reduces the frequency of vehicle maintenance and operating costs. The car floor 1 forms a stable connection with the frame, effectively improving the overall rigidity and operational stability of the freight car system under complex track conditions and heavy load conditions. It provides a higher standard of safety and better dynamic performance for container transportation, significantly enhancing the comprehensive technical competitiveness of railway freight equipment.

[0042] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
