Description

Technical Field

[0001] This utility model relates to a movable loading mechanism for loading train carriages, belonging to the field of train carriage loading technology. Background Technology

[0002] Freight train transportation is the core of railway freight transport. It mainly uses standardized freight cars to load various goods and features large capacity, low cost, and high stability. It is suitable for transporting bulk goods and some scattered goods over medium and long distances.

[0003] The high height of train carriages used for transporting goods presents challenges such as difficulty in loading and high labor intensity. Existing technologies regarding train carriage loading are scarce and have limited applicability. For example, patent application number 202022021583.X discloses an automatic multi-ditch loading device for trains, including a loading tower, train carriages, tracks, and a tractor. The tractor is connected to the train carriages. A winch is located at the leftmost end of the tracks, equipped with an absolute encoder for positioning the train carriages. A set of cumulative scales is installed on the loading tower, with a telescopic ditch below each scale. The telescopic ditch is connected to a ditch motor, which controls its lifting and lowering. The winch is connected to the lower part of the tractor via a steel cable. A pull-wire sensor is installed on the telescopic ditch, and a laser rangefinder is installed on the side of the ditch to measure the real-time height of the loaded material. A leveling device is installed at the lower end of the loading tower to compact and level the material inside and on top of the train carriages. While this patent addresses the technical problems of high labor costs and low efficiency in existing technologies to some extent, it is mainly applied to grain terminal transportation and requires fixed buildings, resulting in complex structures and poor adaptability. Utility Model Content

[0004] This utility model provides a movable loading mechanism for loading train carriages, which is applicable to loading various materials such as powder, granules, and fibers into train carriages. It has a simple structure, is easy to use, and is movable, making it easy to promote.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A movable loading mechanism for loading train carriages includes a base, a lifting platform, a material chute structure, a lifting device, and a lifting guide column;

[0007] The lifting platform is located on the base; a stop post is provided at the end of the upper surface of the lifting platform; the angle of the material chute structure is adjustable at the end of the lifting platform.

[0008] There are two sets of lifting devices, which are symmetrically arranged on both sides of the lifting platform. Each set of lifting devices includes at least two hydraulic lifting cylinders. The fixed end of each hydraulic lifting cylinder is connected to the base, and the drive end of each hydraulic lifting cylinder is connected to the lifting platform.

[0009] The lifting guide columns are arranged in pairs on both sides of the lifting platform, and the bottom of the lifting guide columns is vertically connected to the base.

[0010] The lifting platform has guide frames on both sides corresponding to each guide column; each guide column is matched inside the corresponding guide frame and can slide up and down relative to the guide frame.

[0011] The base and the lifting platform are aligned along their length. The direction from one end to the other is also aligned with the length direction of the base and the lifting platform. The direction from one side to the other of the base and the lifting platform is perpendicular to their length direction.

[0012] When in use, place the movable loading mechanism for loading train cars at the desired location, so that the end of the lifting platform points towards the train car (when the front end of the truck bed is lifted and in the unloading state, the opening at the end of the truck bed points into the train car). Reverse the truck loaded with goods onto the lifting platform (with the truck's front pointing towards the beginning of the platform and the truck bed pointing towards the end), stopping the truck's reversing as its rear wheels are engaged with the bollards. Then, simultaneously activate both lifting devices, with the hydraulic cylinders on both sides driving the platform upwards at the same speed. During the ascent, the platform remains horizontal, stopping when it reaches the designated height. Adjust the material chute to a downward angle, with its end pointing towards the train car. Lift the beginning of the truck bed (this is a built-in function of existing trucks; select trucks with this function when loading into train cars), with the end of the truck bed pointing towards the train car. Open the truck bed door at the end of the truck bed, and the materials inside will automatically fall into the train car under gravity. The material chute effectively guides and collects materials, reducing or preventing spillage and minimizing losses. After all the material in the truck bed has been unloaded, lower the front end of the truck bed, control the lifting device to bring the lifting platform to the initial position, and drive the truck off; repeat the above steps to complete the loading of the train car.

[0013] The hydraulic lifting cylinders in this application all adopt a one-way action cylinder structure, with a retractable drive end (including piston rod) at the top and a non-retractable fixed end at the bottom, which is directly anchored to the base.

[0014] To improve the stability of the device, the material chute structure includes a material chute, a connecting rod, and a drive cylinder;

[0015] One end of the material chute is a connecting end and the other end is a free end. The two sides of the connecting end of the material chute are hinged to the two sides of the end of the lifting platform through connecting ears.

[0016] There are two connecting rods, which are arranged opposite each other between the connecting end and the free end on both sides of the back side of the material chute;

[0017] There are two drive cylinders, which are tilted and set opposite to each other. The fixed ends of the two drive cylinders are respectively connected to the two sides of the end of the lifting platform, and the drive ends of the two drive cylinders are respectively hinged to the connecting rod on the side where they are located.

[0018] The aforementioned drive cylinder adopts a one-way action cylinder structure, with one end being a retractable drive end (including piston rod) and the other end being a non-retractable fixed end.

[0019] To reduce material loss, the sides of the material chute are equipped with baffles. The baffles on both sides of the connecting end of the material chute are respectively hinged to the two ends of the lifting platform through connecting ears.

[0020] To facilitate reversing a car onto the lifting platform, the first end of the lifting platform extends beyond the first end of the base and downwards to its end, flush with the bottom of the base, forming an inclined transition platform. In use, the base rests directly on the ground; this inclined transition platform creates a smooth transition, allowing the car to easily reverse onto the lifting platform.

[0021] To facilitate the movement of the loading mechanism, the base is rectangular, with both sides extending beyond the lifting platform. Height-adjustable casters are installed at the four corners of the base extending beyond the lifting platform. When movement is required, the casters are lowered to extend beyond the bottom of the base, providing support on the ground for easy movement. When the vehicle is in a designated position, the casters are raised until they are above the bottom of the base, at which point the bottom of the base touches the ground, facilitating loading. The structure of the height-adjustable casters in this application can utilize existing structures. This application does not offer any significant improvements and will not elaborate further.

[0022] To facilitate the arrangement and installation of hydraulic lifting cylinders, mounting brackets corresponding to each hydraulic lifting cylinder are provided on both sides of the lifting platform. The mounting brackets are U-shaped structures with the opening facing downwards. The bottom ends of the mounting brackets are connected to the lifting platform, and the fixed end of each hydraulic lifting cylinder is connected to the base, while the driving end is connected to the center of the top of the corresponding mounting bracket.

[0023] To facilitate reversing, the upper surface of the lifting platform is coated with two white guide lines running along its length. This provides a guiding effect and makes reversing easier.

[0024] To further enhance safety, the lifting platform is equipped with two length-oriented limiting grooves on both sides, with anti-slip textures at the bottom of the grooves. These grooves correspond to the two rows of wheels of a truck, ensuring that the truck's wheels fall precisely within them during operation. This effectively guides, limits, and prevents slippage, significantly improving truck positioning accuracy and operational safety, while also making operation convenient and efficient.

[0025] To further facilitate use, each limiting groove is coated with white guide lines, which serves as an additional indicator. Each limiting groove has a stop post at its end; when the ends of both rows of wheels of the truck become stuck on the stop post, the reversing operation stops.

[0026] To further improve the stability of the lifting platform, each lifting device has hydraulic lifting cylinders distributed at least at both ends of the base length direction; the hydraulic lifting cylinders of the two lifting devices are arranged opposite each other in pairs.

[0027] The two sets of lifting devices are positioned opposite each other on both sides of the lifting platform, with one set on each side. Each set of lifting devices integrates no fewer than two hydraulic lifting cylinders. This design significantly improves the stability of the lifting process. In the event of a failure in a single cylinder, it can effectively prevent the platform from tilting, the vehicle from skidding or overturning, thus avoiding major safety accidents.

[0028] The length of the base and the lifting platform in this application is parallel to the direction in which the vehicle travels on the lifting platform.

[0029] To improve structural strength, the base is a frame structure, and the lifting platform includes a support frame and a base plate mounted on the support frame. The support frame is also a frame structure. Both the base and the support frame are made of Q355 manganese steel, and the base plate is made of 7.5# checkered plate. This significantly enhances the overall structural rigidity.

[0030] Any technologies not mentioned in this utility model are based on existing technologies.

[0031] This utility model relates to a movable loading mechanism for loading train carriages. Driven by a lifting device, the lifting platform rises along the lifting guide column, thereby lifting the truck on the platform. This facilitates the direct loading of materials from the truck bed into the train carriage, improving loading efficiency. The material chute effectively guides and collects materials, reducing or preventing spillage and minimizing losses. The symmetrical layout of multiple hydraulic cylinders on both sides fundamentally ensures lifting stability and safety under loads of tens to hundreds of tons. Even if a single hydraulic cylinder fails, the platform remains level, eliminating the risk of tipping over, ensuring a reliable and stable structure. Furthermore, anti-slip limiting grooves are installed on the lifting platform, providing guidance, limiting, and anti-slip functions, significantly improving truck positioning accuracy and operational safety, and making operation convenient and efficient. Height-adjustable wheels ensure overall rigid support during lifting operations and facilitate flexible movement of the equipment between workstations. The structure is simple and adaptable.

This significantly enhances the overall structural rigidity. In this example, the weight of the movable loading mechanism is approximately 18 tons.

[0074] The aforementioned movable loading mechanisms for loading train carriages, driven by a lifting device, allow the lifting platform to rise along the lifting guide column, thereby lifting the truck on the platform.
