Description

Technical Field

[0001] This utility model relates to the field of cargo transportation technology, specifically a self-unloading transport trolley. Background Technology

[0002] Freight transport refers to the process of moving goods from an origin to an end point using various modes of transportation (such as road, rail, air, and sea), and it is a core link in the logistics system. Handling trolleys play a crucial role in freight transport; they are specialized devices used for loading, unloading, moving, and securing goods, effectively improving transport efficiency and cargo safety. During loading and unloading, handling trolleys can quickly complete the process, reducing labor costs; during warehousing and transportation, securing goods to the trolley prevents slippage or falling, ensuring cargo stability and safety.

[0003] Current unloading methods typically rely on manual handling, which is inefficient and time-consuming, leading to increased labor costs and bottlenecks in the workflow. Workers' handling efficiency is affected by physical strength and skill; fatigue can cause accidents or damage to goods, further increasing costs. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 A self-unloading transport trolley includes a base 1. A first fixing frame 11 is fixedly installed at the top of the base 1, supporting a rotating shaft 12. The rotating shaft 12 is rotatably inserted within the first fixing frame 11. A platform 13 is fixedly installed on the outer side of the first rotating shaft 12, and goods are placed on top of the platform 13 for transfer. The platform 13 can rotate on the rotating shaft 12 and is located at the top of the base 1. A second fixing frame 2 is fixedly installed at the top of the base 1, with a rotating rod 21 rotatably inserted within it. The rotation of the rotating rod 21 drives two rotating plates 22 to rotate. Symmetrically distributed rotating plates 22 are fixedly installed on the outer side of the rotating rod 21, and the rotation of the rotating plates 22 causes two connecting plates 23 to swing. A connecting plate 23 is rotatably mounted on the end of plate 22 away from the rotating rod 21. By swinging the two connecting plates 23, the platform 13 can be rotated on the rotating shaft 12, which facilitates the unloading of goods. The end of the connecting plate 23 away from the rotating plate 22 is rotatably connected to the bottom end of the platform 13. A U-shaped plate 24 is fixedly provided at the top of the base 1. The U-shaped plate 24 is used to install and position the worm gear 25, etc. The worm gear 25 is rotatably inserted into the U-shaped plate 24. A worm wheel 26 is fixedly provided on the outside of the rotating rod 21. The worm gear 25 and the worm wheel 26 mesh with each other. The rotation of the worm gear 25 drives the rotation of the worm wheel 26, and the rotation of the worm wheel 26 drives the rotation of the rotating rod 21, which facilitates the unloading of goods and avoids the problem of cumbersome manual unloading.

[0025] A connecting block 3 is fixedly provided at the bottom of the platform 13. The connecting block 3 is used to connect the platform 13. A connecting hole 31 is provided in the connecting block 3. A fixing block 32 is fixedly provided at the top of the U-shaped plate 24. A threaded rod 33 is threadedly inserted into the fixing block 32. An insert rod 34 is fixedly provided at the end of the threaded rod 33. The platform 13 can be positioned by inserting the insert rod 34 into the connecting hole 31. When not in use, the platform 13 and the goods will not tip over. The insert rod 34 is movably inserted into the connecting hole 31. The rotation of the threaded rod 33 drives the insert rod 34 to rotate and move at the same time, so that the insert rod 34 is inserted into the connecting hole 31 on the inner side of the connecting block 3, thereby reinforcing the platform 13.

[0026] A drive assembly 15 is installed at the bottom of the base 1. The drive assembly 15 mainly consists of drive wheels and electric drive equipment. The drive wheels drive the entire device to move, and can also transport goods.

[0027] The top of the base 1 is fixed with symmetrically distributed support rods 16, and the platform 13 is located above the support rods 16, so that the support rods 16 can support the platform 13 and improve the stability of the platform 13.

[0028] Side panels 14 are fixedly installed on both sides of the platform 13. The side panels 14 can protect the goods and prevent them from slipping from the side, thus achieving the purpose of protection.

[0029] A roller 17 is rotatably mounted on the top of the platform 13. As the goods move on the platform 13, the roller 17 can assist in unloading the goods.

[0030] A motor 27 is installed on the outside of the U-shaped plate 24. The end of the output shaft of the motor 27 is inserted through the U-shaped plate 24 and fixedly connected to the worm gear 25, so that the end of the output shaft of the motor 27 rotates to drive the worm gear 25 to rotate, thereby providing power output.

[0031] A turntable 35 is fixedly provided at the end of the threaded rod 33 away from the insertion rod 34. The rotation of the turntable 35 drives the threaded rod 33 to rotate, thereby driving the threaded rod 22 to rotate while moving laterally.

[0032] In use, the goods to be transported are first placed on the platform 13. Then, the drive assembly 15 transports the device and goods to the designated position. When unloading is required, first, the turntable 35 is rotated, which drives the threaded rod 33 to rotate. As the threaded rod 33 rotates, it moves laterally within the fixed block 32. The movement of the threaded rod 33 drives the insertion rod 34 to move, causing the insertion rod 34 to disengage from the connecting hole 31, thus losing its restraint on the connecting block 3 and the platform 13. Then, the motor 27 is moved to start working. The output shaft of the motor 27 rotates, driving the worm gear 25 to rotate. The worm gear 25 rotates, driving the meshing worm wheel 26 to rotate. The worm wheel 26 rotates, driving the rotating rod 21 to rotate. The rotating rod 21 rotates, driving the two rotating plates 22 to rotate. The two rotating plates 22 rotate, causing the two connecting plates 23 to swing. The swinging of the connecting plates 23 causes the platform 13 to rotate on the rotating shaft 12, thus causing the goods to tilt. Then, the platform 13 slowly rotates, causing the goods to slide downwards due to gravitational potential energy. At this time, in conjunction with the drive component 15, the device moves, thus allowing the goods to be unloaded automatically, avoiding the problems of cumbersome and inefficient manual operation.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
