Description

Technical Field

[0001] This utility model relates to the field of oil drum transfer technology, and in particular to an oil drum transfer and refueling trolley with a buffer tray. Background Technology

[0002] Oil drum transshipment is a sub-segment of the logistics and petrochemical industries. It mainly involves the safe and efficient transfer and handling of oil drums containing oil products, various liquids, and some solid chemical raw materials at different locations. Large chemical enterprises and oil storage and logistics centers build automated oil drum conveyor lines. Through the cooperation of conveyor belts, rollers, and robotic arms, the entire process of oil drum transfer, from production and packaging to storage area and loading onto trucks, is automated. This greatly improves the efficiency and accuracy of transfer. Transferring and subsequent disposal in accordance with regulations also meets environmental protection requirements and helps reduce adverse impacts on the ecological environment.

[0003] In the actual transfer of oil drums, direct manual handling carries certain risks. To ensure transportation efficiency and mitigate risks, transfer carts are often used to assist in the work. Most existing transfer carts use an integrated welded fixing structure, which can effectively fix the oil drums and reduce their shaking during transportation. However, due to its own structure, the cart has poor versatility and is difficult to adapt to many oil drums of different sizes. This limits the application scenarios of the transfer carts and increases transportation costs. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an oil drum transfer and refueling trolley with a buffer tray, aiming to improve the problem of poor versatility of trolleys in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a drum transfer and refueling trolley with a buffer tray, comprising a curved beam, a connecting seat fixedly connected to the outer wall of the curved beam, a vertical beam fixedly connected to the top rear side of the connecting seat, a turntable rotatably connected to the center of the bottom surface of the connecting seat, movable wheels fixedly connected to the bottom of the turntable and the curved beam near their edges, a connecting rod fixedly connected to the bottom rear side of the connecting seat, a rotating shaft rotatably connected to the bottom end of the connecting rod, a buffer tray rotatably connected to the outer wall of the rotating shaft, a sliding groove provided on both the left and right sides of the outer wall of the vertical beam, a movable seat slidably connected to the inner wall of the sliding groove, a screw threadedly connected to the inner wall of the movable seat, a rotating block fixedly connected to the top end of the screw, a soft pad fixedly connected to the bottom end of the screw, and an auxiliary mechanism fixedly connected to the outer wall of the buffer tray, the auxiliary mechanism being used to assist in the transfer of the drum.

[0006] As a further description of the above technical solution: The auxiliary mechanism includes multiple connecting plates, with each adjacent side of the connecting plates fixedly connected to the outer wall of the buffer plate. Pneumatic rods are fixedly connected to the bottom left and right sides of the curved beam, with the output end of each pneumatic rod fixedly connected to the center of the top surface of the connecting plate. Multiple spring cylinders are fixedly connected to the top of the connecting plate near its edge, with buffer springs fixedly connected to the bottom of the inner wall of each spring cylinder. A pressure rod is slidably connected to the center of the inner wall of each spring cylinder. A friction plate is fixedly connected to the bottom of the buffer plate. A second sliding groove is provided on the top right side of the curved beam, with a slider slidably connected to the inner wall of the second sliding groove. A railing is rotatably connected to the top of the slider, and a locking block is fixedly connected to the bottom of the railing. Multiple locking slots begin on the top left side of the curved beam.

[0007] As a further description of the above technical solution: A nameplate is fixedly connected to the top front side of the connector, and an oil storage tank is provided on the top of the buffer plate.

[0008] As a further description of the above technical solution: A connecting block is fixedly connected to the front side of the outer wall of the vertical beam, and an installation groove is provided on the front side of the outer wall of the connecting block.

[0009] As a further description of the above technical solution: The inner wall of the mounting groove is fixedly connected to a movable handle, and the outer wall of the movable handle is fixedly connected to a rubber ring.

[0010] As a further description of the above technical solution: A controller is fixedly connected to the inner wall of the connecting block, and a rotating shaft is rotatably connected to the top of the connecting block.

[0011] As a further description of the above technical solution: A cover plate is fixedly connected to the outer wall of the rotating shaft, and a handle is fixedly connected to the top of the cover plate.

[0012] As a further description of the above technical solution: The top end of the pressure rod is fixedly connected to the bottom of the curved beam, and the bottom end of the pressure rod is fixedly connected to the top of the buffer spring.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the oil storage tank is first placed on top of the buffer plate, and the oil storage tank is pushed so that one side of it contacts the rear side of the connecting seat. Then, the moving seat is slid down to a suitable position. Then, by rotating the rotating block, the screw is driven to rotate and move down along the inner wall of the moving seat, causing the soft pad at its bottom to move down and contact the top of the oil storage tank. By rotating the rotating block, the pressure of the soft pad on the oil storage tank is increased, thereby locking the oil storage tank between the soft pad and the buffer plate, thus completing the fixation of the oil storage tank. Then, it is transported, thereby achieving the purpose of effectively fixing oil storage tanks of different sizes, expanding the application scenarios of the transport trolley and reducing transportation costs.

[0014] 2. In this utility model, the pneumatic rod extends downward by starting the controller. Since the buffer plate and the rotating shaft are in a rotating relationship, the buffer plate rotates around the rotating shaft. The rear side of the buffer plate moves downward, so that the friction plate contacts the ground, increasing the friction force. Then, the oil storage tank is pushed onto the buffer plate. Then, the pneumatic rod is controlled to retract. The function of the buffer spring is to slow down the speed of the buffer plate and prevent the oil in the oil storage tank from spilling out due to excessive speed. Then, the sliding railing is used to lock the locking block into the slot closest to the oil storage tank. Through the above operations, the purpose of assisting in handling and fixing 15 is achieved, increasing practicality. Attached Figure Description

[0022] Working principle: When it is necessary to transfer the oil storage tank 15, first place the oil storage tank 15 on the top of the buffer plate 9, push the oil storage tank 15 so that one side of it contacts the rear side of the connecting seat 3, then slide the moving seat 10 down to the appropriate position, and then rotate the rotating block 14 to drive the screw 13 to rotate and move down along the inner wall of the moving seat 10, which will drive the soft pad 12 at the bottom to move down and contact the top of the oil storage tank 15. By rotating the rotating block 14, the pressure of the soft pad 12 on the oil storage tank 15 is increased, thereby locking the oil storage tank 15 between the soft pad 12 and the buffer plate 9, thus completing the fixation of the oil storage tank 15, and then transferring it. When the oil storage tank 15 is full of oil, it is difficult to move it directly onto the buffer plate 9. First, the pneumatic rod 208 is extended downward by starting the controller 21. Since the buffer plate 9 and the rotating shaft 8 are in a rotating relationship, the buffer plate 9 rotates around the rotating shaft 8. The rear side of the buffer plate 9 moves down, so that the friction plate 206 contacts the ground, increasing the friction force. Then, the oil storage tank 15 is pushed onto the buffer plate 9. Then, the pneumatic rod 208 is controlled to retract. The function of the buffer spring 211 is to slow down the speed of the buffer plate 9 and prevent the oil in the oil storage tank 15 from spilling out due to excessive speed. Then, the sliding rail 201 is used to lock the locking block 202 into the locking groove 203 closest to the oil storage tank 15, which helps to fix the oil storage tank 15.
