[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present utility model can be combined with each other, and the described embodiments are only some embodiments of the present utility model, not all embodiments.

[0017] See Figure 1-2This embodiment describes a foot-operated hydraulic trolley for easy loading and unloading of a rotating drum. It includes a frame body 1, a hydraulic cylinder 2, a lifting pedal 3, and a lifting platform 4. The hydraulic cylinder 2 is located at the bottom of one side of the frame body 1, and the lifting platform 4 is positioned at the other side of the frame body 1 for placing the rotating drum. The lifting pedal 3 is connected to the bottom of one side of the hydraulic cylinder 2, and controls the upward movement of the piston rod of the hydraulic cylinder 2. A pressure relief handle 5 is located on the top side of the frame body 1, and the pressure relief handle 5 is connected to the hydraulic cylinder 2 via a hydraulic transmission line 6 and controls the downward movement of the piston rod of the hydraulic cylinder 2. The rotating drum is placed on the lifting platform 4 of the device. The lifting platform 4 mechanism is hydraulically driven by the lifting pedal 3 and the pressure relief handle 5, replacing the traditional manual lifting method. This significantly reduces safety hazards such as falls and sprains during the loading and unloading of the rotating drum. The hydraulic lifting platform can smoothly support the rotating drum, avoiding the physical exertion and operational risks caused by manual handling.

[0018] In this embodiment, the drum is raised using a foot-operated hydraulic system, which is convenient for lifting the drum as it is in a standing position during operation.

[0019] In this embodiment, the drum is lowered by pressing the pressure relief handle 5. Since the drum is in a standing position when it is working, pressing the handle makes it easy to lower the drum.

[0020] In this embodiment, the top of the lifting platform 4 near the main body 1 is connected to a lifting baffle 7. The lifting baffle 7 is used to assist the lifting platform 4 in placing and fixing the drum, and to reduce the pressure of the drum on the lifting platform 4.

[0021] In this embodiment, the frame body 1 is provided with slide rods 8 on both sides, and the lifting baffle 7 is provided with two linear bearings 9 that cooperate with the two slide rods 8. The lifting baffle 7 is slidably connected to the slide rods 8 through the linear bearings 9.

[0022] In this embodiment, a connecting plate 14 is provided between the two linear bearings 9. The connecting plate 14 is connected to the piston rod of the hydraulic cylinder 2. The piston rod of the hydraulic cylinder 2 drives the two linear bearings 9 to slide on the slide rod 8 through the connecting plate 14, thereby controlling the lifting platform 4 on the frame body 1.

[0023] In this embodiment, handles 10 are provided on both sides of the top of the frame body 1. The pressure relief handle 5 is located below one of the handles 10. The handle 10 is used by the staff to hold and push or pull the cart to realize the transfer of the drum.

[0024] In this embodiment, a spring clamp 11 is provided on one side of the frame body 1. The spring clamp 11 is located above the lifting platform 4 and is used to clamp the drum to assist in fixing the drum.

[0025] In this embodiment, a drain hole 12 is provided on one side of the lower end of the lifting baffle 7. The drain hole 12 is used for drainage when cleaning the drum.

[0026] In this embodiment, wheels 13 are provided on both sides of the bottom of the main frame 1.

[0027] In this embodiment, anti-slip pads are provided on the inner side of the spring clamp 11 and the top of the lifting platform 4 to reduce the friction when rotating the drum cover and increase the friction of the drum in other directions.

[0028] In this embodiment, the lifting platform 4 is horseshoe-shaped, which better matches the shape of the bottom of the drum, increases the contact area between the bottom of the drum and the lifting platform 4, and increases stability.

[0029] The working principle of this embodiment is as follows: When loading and unloading the drum, step on the lifting pedal 3. At this time, the piston rod of the hydraulic cylinder 2 pushes the connecting plate 14, thereby driving the linear bearing 9 to rise along the slide bar 8. When the lifting baffle 7 and the lifting platform 4 rise synchronously to the height of the drum, push the drum into the lifting platform 4. Its bottom arc surface fits against the horseshoe-shaped platform surface, and its back abuts against the lifting baffle 7. Move the spring clamp 11 to clamp the upper edge of the drum. The anti-slip pad prevents slippage. After the trolley is pushed by the handle 10 to transfer the drum to the target position, move the pressure relief handle 5. The hydraulic cylinder 2 slowly releases pressure. Wait for the lifting platform 4 to descend smoothly to the ground to complete the unloading.

[0030] The embodiments of the present invention disclosed above are merely illustrative of the present invention. The embodiments do not exhaustively describe all details, nor do they limit the present invention to the specific implementations described. Many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention.
