Abstract
Description
Technical Field
[0001] This utility model specifically relates to a loading and unloading device for railway freight transportation, belonging to the field of railway freight transportation technology. Background Technology
[0002] The daily workload of railway freight wagons currently fluctuates significantly, exhibiting a clear imbalance that makes it difficult to maintain a large workforce for loading and unloading in the long term. Furthermore, when there is a concentrated shipment or arrival of bagged goods such as fertilizers and grains, it is impossible to quickly replenish temporary manpower, resulting in high loading and unloading pressure and low vehicle turnover efficiency. Under these circumstances, delays in loading and unloading, extended operating times, and slow turnover of freight cars and cargo spaces often occur, severely impacting overall transportation efficiency.
[0003] A Chinese utility model patent, publication number CN222973395U, discloses a mobile loading and unloading device suitable for railway freight boxcars. This device works by engaging hooks one and two into hanging rings on a mobile cart, and then activating motor three to rotate a take-up reel, tightening the steel wire rope two, thereby driving the mobile cart closer to the cargo stacking area. Workers can place goods on the mobile cart. Once a certain quantity is loaded, motor two is activated again, rotating the take-up reel and tightening the steel wire rope one, pulling the mobile cart towards the railway boxcar. Two workers then transfer the goods to a conveyor belt, repeating the process to achieve the reciprocating movement of the mobile cart. This design effectively reduces the intensity of manual handling, improves loading and unloading efficiency, and enhances the practicality of the equipment.
[0004] However, in actual operation, it was found that after the workers unloaded the goods at the door of the wagon, they still had to manually move the goods on both sides of the wagon to the loading and unloading device. This process was labor-intensive and inefficient, not only consuming a lot of physical strength but also reducing the overall loading and unloading speed. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of the existing technology by providing a loading and unloading device for railway freight, so as to achieve the above-mentioned objectives.

One end of the first dustproof telescopic soft sleeve is fixedly connected to the second movable seat, and the other end of the first dustproof telescopic soft sleeve is fixedly connected to the surface of the vehicle body.
[0009] Furthermore, the protrusion of the rotating block has a rotating seat inside that matches the size of the threaded rod, and the two rotating seats are arranged vertically.
[0010] Furthermore, the extension assembly includes a second electric telescopic rod, a second dustproof telescopic sleeve, and a push plate. The second electric telescopic rod is fixedly connected to the base. The second dustproof telescopic sleeve is fitted over the surface of the second electric telescopic rod, and one side of the second dustproof telescopic sleeve is fixedly connected to a third movable seat. The other side of the second dustproof telescopic sleeve is fixedly connected to the push plate, and one side of the push plate is fixedly connected to a fourth movable seat.
[0011] Furthermore, the second conveyor includes two sets of second rollers and a second conveyor belt. The two sets of second rollers are rotatably connected to the fourth movable seat and the third movable seat, respectively, and the two sets of second rollers are drive-connected to the second conveyor belt.

[0013] Beneficial effects:
[0014] In this application, rotating the right-side threaded rod sequentially disengages it from the threaded hole and the interior of the rotating seat, releasing the fixation on the rotating seat and simultaneously releasing the right-side fixation of the third movable seat. Then, rotating the left-side threaded rod disengages it from the left-side threaded hole, releasing the fixation on the rotating block. The third movable seat is then pushed, causing the rotating block to rotate 90° to the left. This rotation of the third movable seat, via the second electric telescopic rod and the second dustproof telescopic sleeve, causes the fourth movable seat to rotate 90°. Activating the third electric telescopic rod pushes the support seat, causing the third rotating wheel to move upwards, thus releasing the second conveyor belt. Activating the second electric telescopic rod then pushes the push plate, causing the fourth movable seat to move. This causes the fourth movable seat to pull the second rotating wheel, moving the fourth movable seat to the side of the goods. Finally, activating the first electric telescopic rod retracts it, causing it to push the second movable seat, moving its right side to the material inlet of the second conveyor. This achieves the effect of workers handling goods inside the trolley, reducing the physical and labor consumption of workers. Attached Figure Description
