[0003] In railway logistics loading and unloading operations, efficient and flexible loading and unloading equipment is crucial for improving overall logistics efficiency. Existing technologies, such as the lifting device for railway logistics loading and unloading disclosed in patent CN 211283590 U, have solved the problem of lifting and conveying goods to a certain extent. It uses a base, symmetrically arranged support columns, and a top plate to form a portal frame structure. Supporting triangular plates slidably mounted on the support columns support the lifting and conveying device, enabling the transfer of goods between different heights. However, this device has significant limitations. In actual railway logistics loading and unloading scenarios, factors such as the type of goods, packaging, and the structure of the carriages vary considerably. Because the device cannot adjust the conveyor slope, it is difficult to adjust the conveyor angle according to actual needs for some goods that require gravity-assisted sliding, thus affecting the loading and unloading speed and efficiency. Furthermore, when dealing with train carriages of varying heights and structures, the inability to adjust the slope of the conveyor device prevents the formation of an ideal conveyor angle when docking carriages, making loading and unloading difficult and even causing damage to the goods.

[0004] With the rapid development of the railway logistics industry, higher requirements have been placed on the functionality and adaptability of loading and unloading equipment. In order to meet diverse loading and unloading needs and improve the overall efficiency of railway logistics loading and unloading, it is necessary to develop a lifting device for railway logistics loading and unloading with an adjustable conveyor slope.

[0017] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] Figures 1 to 3 A lifting device for loading and unloading railway logistics is presented, including a base 110, which serves as the foundation of the entire device, providing stable support and ensuring that the device will not easily shake or tip over during operation. Columns 100 are provided on the left and right sides of the base 110. The top of each column 100 is equipped with a top plate to form a portal-shaped support frame, making the device structure more robust. Supporting triangular plates 200 are slidably mounted on the columns 100, providing guidance and support for the movement of the supporting triangular plates 200. An adjustable-slope lifting and conveying device is installed on the supporting triangular plates 200, thereby achieving coordinated adjustment and coordination of the height and slope of the conveying device. The specific implementation method is as follows: The supporting triangular plate 200 is the load-bearing structure of the lifting and conveying device, and also provides an installation base for slope adjustment-related components. Adjustable wing plates 210 are provided at both ends of the supporting triangular plate 200, and arc-shaped sliding grooves 211 are formed on the adjustable wing plates 210. The lifting and conveying device includes mounting side plates 310, and a conveying unit 300 is installed between the mounting side plates 310.

[0019] The mounting plate 310 is provided with a sliding column 312 that passes through and slides with the arc-shaped sliding groove 211. The arc-shaped sliding groove 211 provides a path for the sliding column 312 to slide, and plays a guiding role in adjusting the slope of the lifting and conveying device. A slope adjusting telescopic rod 400 for driving the sliding column 312 to slide is also installed on the supporting triangular plate 200. The two ends of the slope adjusting telescopic rod 400 are respectively hinged to the bottom of the sliding column 312 and the supporting triangular plate 200. The mounting plate 310 is used to support the conveying unit 300 and is connected to the sliding column 312, driving the conveying unit 300 to move with the sliding column 312 to achieve slope adjustment. The conveying unit 300 is directly used to convey goods and is a core working component in the loading and unloading process of railway logistics goods.

[0020] The structure of the conveying unit 300 is as follows: it includes conveying wheels 320 rotatably mounted at both ends of the mounting side plate 310, and a conveying chain plate or conveyor belt is mounted on the conveying wheels 320; the conveying wheels 320 include a driving wheel and a driven wheel, and the rotating shaft of the driving wheel is connected to the output end of the conveying drive device.

[0021] Regarding the selection of the drive device, the slope adjustment telescopic rod 400 is an electric cylinder or a hydraulic cylinder, and the lifting drive device 500 and the transmission drive device (not shown in the figure) are electric motors or hydraulic motors.

[0022] The working process of the lifting device for railway logistics loading and unloading is as follows: When railway logistics loading and unloading operations are required, the supporting triangular plate 200 is driven to slide up and down along the column 100 through the relevant drive mechanism according to the target height of the cargo loading and unloading, so as to adjust the lifting and conveying device to a suitable height position.

[0023] Secondly, after the height is determined, if the conveyor slope needs to be adjusted, the slope adjustment telescopic rod 400 is activated. When the slope adjustment telescopic rod 400 extends or retracts, it causes the sliding column 312, which is hinged to it, to slide along the arc-shaped groove 211 on the adjustment wing plate 210. Since the sliding column 312 is connected to the mounting side plate 310, the sliding of the sliding column 312 will cause the mounting side plate 310 and the conveyor unit 300 installed between the mounting side plates 310 to move together, thereby changing the tilt angle of the conveyor unit 300 and realizing the adjustment of the conveyor slope. The slope adjustment can also be performed synchronously with the height adjustment.

[0024] Finally, when the height and slope are adjusted to meet the loading and unloading requirements, the conveying unit 300 is started, and the lifting device can be used to load and unload goods, completing the conveying of goods under different height and slope conditions.

[0025] In another preferred embodiment, the column 100 is a channel steel or I-beam with an inner groove. The inner groove is provided with a lead screw 510 and a guide column 520, which are respectively installed on the top plate and the base 110. The top plate is also equipped with a lifting drive device 500 for driving the lead screw 510 to rotate.

[0026] Both channel steel and I-beams are profiles with excellent cross-sectional properties, possessing high structural strength and stability. Using them as column 100 provides robust support for the entire portal frame, effectively bearing the weight of the supporting triangle plate 200, the lifting and conveying device, and the cargo. This ensures the device is not easily deformed during long-term, high-intensity loading and unloading operations, guaranteeing the overall structural stability and service life of the device. Simultaneously, its built-in inner groove serves as the installation space for the lead screw 510, guide column 520, and supporting triangle plate 200 to slide, eliminating the need for additional installation structures and simplifying the processing and assembly of column 100.

[0027] In another preferred embodiment, a slider 220 that fits into the inner groove is provided on the outer side of the supporting triangular plate 200. The slider 220 has a thread hole and a guide hole that respectively fit into the lead screw 510 and the guide post 520.

[0028] As a connecting component between the supporting triangle plate 200 and the column 100, the slider 220, with its fitting and engaging structure with the inner groove of the column 100, enables the supporting triangle plate 200 to be stably installed on the column 100, preventing lateral offset or swaying of the supporting triangle plate 200 during its up-and-down sliding, ensuring the smoothness of the movement of the supporting triangle plate 200, and thus providing a stable support foundation for the lifting and conveying device.

[0029] The guide hole and guide post 520 work together to guide and limit movement. When the lead screw 510 drives the slider 220, the guide post 520 restricts the rotation of the slider 220, ensuring that the slider 220 can only move linearly along the axis of the column 100, preventing the slider 220 from rotating with the lead screw 510 and affecting the stability and accuracy of height adjustment. At the same time, the guide post 520 also shares some of the radial force, reducing the stress between the lead hole and the lead screw 510, and extending the service life of both the lead screw 510 and the slider 220.

[0030] In another preferred embodiment, the outer edge of the adjusting wing plate 210 is an arc shape that matches the arc-shaped slide groove 211, making the overall structure of the adjusting wing plate 210 more harmonious.

[0031] The mounting side plate 310 is provided with a lock hole on its outer side, and the adjusting wing plate 210 is provided with a plurality of limiting holes 212 distributed along the arc shape on the outer side of the arc-shaped slide groove 211; it also includes a locking pin adapted to the lock hole and the limiting hole 212 for mechanically locking the slope of the lifting and conveying device.

[0032] After the lifting and conveying device is adjusted to a suitable slope using the slope adjustment telescopic rod 400, the position of the lifting and conveying device can be firmly fixed by passing a locking pin through the locking hole on the mounting side plate 310 and the corresponding limiting hole 212 on the adjusting wing plate 210. This avoids slope deviation that may occur due to fatigue of the telescopic rod, insufficient hydraulic or pneumatic pressure, etc., when the slope is maintained solely by the driving force of the slope adjustment telescopic rod 400, ensuring that the conveying slope remains stable throughout the loading and unloading process.

[0033] Meanwhile, the mechanical locking structure provides double protection for slope adjustment. Even in an emergency where the slope adjustment telescopic rod 400 malfunctions, the locking pin can still reliably lock the transmission slope, preventing safety accidents such as equipment damage or personal injury caused by sudden changes in slope, and greatly improving the safety of railway logistics loading and unloading operations.
