In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0035] See Figure 1 A preferred embodiment of the present application shows an acid barrel transfer cart comprising a cart frame 1, a roller bracket 2, a drive mechanism 3, and a proximity sensor 4. The roller bracket 2 is mounted on the cart frame 1 in a traversable manner and is equipped with a plurality of horizontally disposed transfer rollers 21 that can be controlled to rotate. The drive mechanism 3 is mounted on one side of the cart frame 1 to automatically move the cart frame 1. The proximity sensor 4 is mounted on the other side of the cart frame 1 facing the loading direction to detect the distance between the cart and the equipment.

[0036] According to the solution of the embodiment of the present invention, by arranging lifting and controllably rotatable transport rollers 21 on the cart frame 1, automatic adjustment of the roller height is achieved; at the same time, the movement and automatic braking of the cart are controlled by the proximity sensor 4 and the drive mechanism 3, so that barrel loading and transportation can be automatically completed, which greatly reduces manpower input and improves compatibility and utilization efficiency.

[0037] The following is a detailed description with specific embodiments:

[0038] Further, see Figure 2 The roller bracket 2 is provided with a lifting mechanism 5 on its side. The lifting mechanism 5 includes a lifting screw 51, a lifting motor 52, and a first transmission chain 53. The lifting screw 51 is vertically arranged next to the cart frame 1. A side plate of the roller bracket 2 is mounted on the lifting screw 51. A first transmission gear 54 is provided on the top of the lifting screw 51. The lifting motor 52 is arranged on a side plate of the roller bracket 2. A first drive gear 55 is provided on the movable end of the lifting motor 52. The first transmission chain 53 is mounted on the first drive gear 55 and the first transmission gear 54. The lifting screw 51, a pair of transmission gears, and the lifting motor 52 are arranged next to the cart frame 1. The first drive gear 55 is connected to the first transmission gear 54 via the first transmission chain 53, enabling the roller bracket 2 to be accurately raised and lowered along the lifting screw 51, ensuring that the transport roller 21 can quickly and accurately match the height of different equipment.

[0039] Further, see Figure 2The roller support 2 is provided with a transport mechanism 6 on its side. The transport mechanism 6 includes a transport motor 61, a second transmission gear 62, and a second transmission chain 63. The transport motor 61 is provided on a side panel of the roller support 2. The movable end of the transport motor 61 passes through the side panel of the roller support 2 and is connected to any transport roller 21. The second transmission gear 62 is provided on the end of the transport roller 21 facing the transport motor 61. The second transmission chain 63 is sleeved on the second transmission gear 62 of the plurality of transport rollers 21. This arrangement allows the loading and unloading of the acid barrels on the cart frame 1 to be completed by electric drive without manual operation.

[0040] Specifically, see Figure 2 The drive mechanism 3 includes a support frame 31, a drive roller 32, and a drive motor 33. The support frame 31 is disposed at the bottom of one side of the cart frame 1, and the drive roller 32 is rotatably disposed within the support frame 31. The drive motor 33 is disposed adjacent to the support frame 31, with its movable end connected to the drive roller 32 for rotating the drive roller 32. The drive motor 33 directly drives the drive roller 32 to rotate, enabling the entire cart to move autonomously on a flat surface, providing a power source for semi-automatic conveying.

[0041] See Figure 1 A mounting plate 7 is provided on one side of the roller bracket 2, facing away from the lifting motor 52. A height sensor 71 is mounted on this mounting plate 7. Furthermore, the acid barrel transfer cart includes a controller, located on one side of the cart frame 1, connected to the lifting motor 52, the transport motor 61, the drive motor 33, the proximity sensor 4, and the height sensor 71. By real-time monitoring of the relative height between the roller bracket 2 and the barrel bottom or the contact surface of the equipment, position information is fed back to the controller, providing a basis for closed-loop control of the lifting mechanism 5.

[0042] Specifically, see Figure 1 A protective frame 8 is provided next to the cart frame 1 to protect the lifting mechanism 5 and the transport mechanism 6. A proximity sensor 4 is provided at the end of the protective frame 8 facing the loading direction. The proximity sensor 4 is placed at the end of the protective frame 8 facing the loading direction. By sensing the distance between the cart and the equipment, a zero-contact automatic shutdown is achieved, ensuring safety while improving the level of automation.

[0043] Further, see Figure 2The pushcart frame 1 is provided with an armrest 11 on one side, and a fixed chain 12 is provided on the armrest 11 for fixing the acid barrel. The pushcart frame 1 is provided with a detachable guardrail 13 on the other side. The pushcart frame 1 is provided with a battery box 9 on one side, and the battery box 9 is used to power the lifting motor 52, the transport motor 61, the drive motor 33, the proximity sensor 4 and the height sensor 71. The armrest 11 is provided on one side of the pushcart frame 1 and is equipped with a fixed chain 12 to stabilize the acid barrel. At the same time, a detachable guardrail 13 is provided on the other side, taking into account both operational convenience and operational safety, making the pushcart easier to operate and maintain during loading and unloading and transportation.

[0044] When the acid barrel transfer cart is in use, the operator turns on the power and pushes the cart to the front of the equipment to be loaded with acid barrels. The proximity sensor 4 automatically identifies the position and brakes to a stop. The controller drives the lifting motor 52 to lift the roller bracket 2 according to the feedback of the height sensor 71 to accurately align with the equipment roller or the bottom of the barrel. The operator opens the cart guardrail 13, places the acid barrel on the controllable rotating transport roller 21, and starts the transport motor 61 to roll it in forward for loading (reverse for unloading). The remote control drive motor 33 then drives the cart to move automatically to the destination. The proximity sensor 4 senses an obstacle on the way and automatically brakes to a stop. After arriving at the unloading point, the lifting motor 52 adjusts the height and the transport motor 61 reverses to roll the acid barrel out smoothly. After loading and unloading are completed, the rollers are retracted and the machine is turned off. The entire process realizes automatic alignment, automatic loading and unloading, and semi-automatic movement, greatly improving efficiency and being compatible with various equipment heights.

[0045] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
