Description

Technical Field

[0001] The present invention relates to a loading and unloading device, in particular to a loading and unloading device for a truck compartment used for large goods. Background Art

[0002] When loading cargo onto a train, a manual tractor or forklift is typically used to transport and lift the cargo into the rear of the train. The cargo is then manually stacked piece by piece from the rear of the train into the depths of the train, requiring both back-and-forth transport and placement. This process is then repeated in reverse when unloading. This method of loading and unloading not only results in low container utilization but also inefficiencies. Large cargo requires the use of large cranes or other machinery, and requires the carriage's roof or side panels to be opened for loading and unloading. This is time-consuming, labor-intensive, and expensive, making it difficult to efficiently and effectively load and unload cargo. Summary of the Invention

[0003] The purpose of the present invention is to solve the problems existing in the prior art and to propose a truck compartment loading and unloading device for large cargo.

[0004] In order to achieve the above-mentioned objectives, the present invention adopts the following technical solutions: a truck compartment loading and unloading device for large cargo, comprising a frame, a cargo device and a cargo pushing device, the frame being a liftable frame with lifting cylinders installed on both sides, a cargo device movable thereon installed on the upper surface of the frame, the cargo device consisting of a cargo flat plate with walking rollers installed on the bottom; the cargo pushing device is installed on the frame by means of groove rails 1 and 2 arranged on both sides of the cargo device, and a row of limit bearing limit columns is vertically arranged on the edge of the top surface of the frame on one side of the cargo device; the cargo device and the cargo pushing device are respectively fixedly connected to a cargo driving assembly and a cargo pushing driving assembly arranged inside the frame and providing driving power.

[0005] As a further technical solution of the present invention, the groove rail one and the groove rail two can be horizontally arranged on the edge of the top surface of the frame, or vertically arranged on the edge of the side wall of the frame, that is, they can be horizontally arranged on both edges of the top surface of the frame or vertically arranged on both side wall edges of the frame at the same time, or one can be horizontally arranged on the edge of the top surface and the other vertically arranged on the edge of the side wall, and can be flexibly arranged according to the width of the table top and the arrangement of the limit columns.

[0006] As a further technical solution of the present invention, the cargo platform is provided with reinforcing ribs at the bottom and a gentle slope is provided at the front end thereof, which can reduce the impact and vibration of the cargo when it falls into the carriage. The cargo platform has a smooth surface and low friction resistance.

[0007] As a further technical solution of the present utility model, the goods pushing device includes a goods pushing base and a goods pushing hydraulic cylinder fixedly installed therein. The hydraulic rod of the goods pushing hydraulic cylinder extends out of the front end of the goods pushing base and is horizontally provided with a goods pushing plate. Both sides of the goods pushing device are slidably installed on a first groove rail and a second groove rail on the frame through dovetail groove rails. The size and height position of the goods pushing plate are adaptively changed according to different specific goods.

[0008] As a further technical solution of the present utility model, the cargo driving assembly includes a speed reduction motor set arranged inside the front end of the frame. The speed reduction motor set is connected to a gear in the middle of a cargo driving power shaft arranged on the frame below the cargo flat plate through a chain. At least two grooves are also arranged on the upper surface of the frame. The cargo driving power shaft passes through the grooves, and gears are installed on the cargo driving power shaft in the grooves. A driven shaft passing through the grooves is installed in the grooves at the other end of the frame, and gears are installed on the driven shaft in the grooves. The gears installed in the grooves on the cargo driving power shaft and the driven shaft are connected by a chain, and the top of the chain is fixedly connected to the bottom of the front end of the cargo flat plate.

The output gear of the goods pushing motor is connected to a goods pushing power shaft gear arranged at the tail end of the frame through a chain. Both ends of the goods pushing power shaft penetrate out of the frame and are fixedly connected with gears. The gears on both sides are connected to gears arranged on both side walls at the front end of the frame through chains, and both side chains are fixedly connected to the bottoms of both sides of the goods pushing device.

First, stack the large goods 7 on the loading flat plate 21 of the loading device 2 and make it lean horizontally against the bearing limit post 12. After the loading device 2 is filled with the goods 7 that the entire carriage 6 can load, start the loading drive assembly 4 to drive the loading device 2 into the carriage 6, and synchronously start the goods pushing drive assembly 5 to make the goods pushing device 3 follow the goods 7. After the entire loading device 2 enters the carriage 6, stop the loading drive assembly 4 and the goods pushing drive assembly 5. Then start the air cylinder to hook the fixed hook 38 of the goods pushing device 3 to the fixed column 14 to fix the goods pushing device 3. Extend the goods pushing plate 21 to further push the goods 7 into the carriage opening to prevent the goods 7 from interfering with the opening and closing of the carriage door. Then start the loading drive assembly 4 to rotate in the reverse direction, so as to retract the loading flat plate 21 of the loading device 2, and the goods 7 will naturally fall on the bottom plate of the carriage 6.
