Abstract
Description
Technical Field
[0001] The utility model relates to a loading and unloading device, in particular to a loading and unloading device for a truck compartment used for long strip 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 back of the train, requiring a back-and-forth process of transporting and stacking. When unloading, the process is repeated in reverse. This method of loading and unloading not only results in low container utilization but also inefficiencies.
[0003] For some long strips or long tubes, they usually need to be loaded one by one, which makes them easy to scatter when piled up. Alternatively, they can be bundled first and then loaded into the truck. Either way is time-consuming and labor-intensive, and the efficiency is too low. Summary of the Invention
[0004] The purpose of the utility model is to solve the problems existing in the prior art and to propose a truck compartment loading and unloading device for long strip goods.
[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a truck compartment loading and unloading device for long-shaped goods, 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 being fixedly connected to a cargo drive assembly arranged inside the frame and providing driving power, the cargo pushing device being installed on the cargo device, and further comprising a cargo blocking device, the cargo blocking device being installed on both side edges of the upper surface of the cargo device.
[0006] As a further technical solution of the present invention, the cargo loading device is composed of a cargo flatbed with walking rollers installed at the bottom; the bottom of the cargo flatbed is provided with reinforcing ribs, and a gentle slope is provided laterally at the front end thereof; the surface of the cargo flatbed is smooth and has low friction resistance, and two long convex rails are also provided on it.
[0007] As a further technical solution of the present invention, the pushing device includes a pushing base, a pushing motor is provided in the pushing base, the pushing motor is connected to the axle of the pushing base wheel installed at the bottom of the pushing base through a gear chain, a telescopic arm is fixed to the upper part of the pushing base, the end of the telescopic arm is connected to the pushing plate, and a pushing plate wheel is installed at the bottom of the pushing plate, and the pushing base wheel and the pushing plate wheel both run on the convex rails on the cargo flatbed.
[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 power shaft arranged on the frame below the cargo flat plate through a chain. At least two grooves are further arranged on the upper surface of the frame. The cargo power shaft passes through the grooves, and gears are installed on the cargo power shaft in the grooves. A driven shaft passing through it is installed in the groove at the other end of the frame, and gears are installed on the driven shaft in the groove. The gears installed on the cargo power shaft and the driven shaft in the grooves are connected through a chain, and the top of the chain is fixedly connected to the bottom of the front end of the cargo flat plate.
[0009] As a further technical solution of the present utility model, the cargo blocking device is two rows of cargo blocking rods arranged on both side edges at the tail end of the cargo flat plate. The distances between the head and tail cargo blocking rods and the heights of the cargo blocking rods are both consistent with the length and height of the truck carriage. Sliding rollers are vertically installed on the side surfaces of the cargo blocking rods facing the cargo flat plate. The setting of the sliding rollers can reduce the friction between the goods and the cargo blocking device when the cargo loading device exits the carriage, preventing the surface of the goods from being worn.
[0010] As a further technical solution of the present utility model, a positioning device is further included. The positioning device includes lifting oil cylinders installed above the outer side walls on both sides of the goods pushing base, lower racks installed below the outer side walls on both sides of the goods pushing base, and upper racks installed on both sides of the tail of the frame. The tooth surfaces of the upper racks and the lower racks are arranged corresponding to each other in opposite directions.
[0011] As a further technical solution of the present utility model, an alignment device is further included. The alignment device includes a bottom plate and a moving plate. The bottom plate is a U-shaped groove, and the moving plate is placed in the U-shaped groove of the bottom plate. Both ends of the moving plate are fixedly connected to a lifting oil cylinder. A window is opened in the middle of the moving plate, and a two-way hydraulic cylinder is installed at the position corresponding to the window on the bottom plate. The hydraulic rods at both ends of the two-way hydraulic cylinder are fixedly connected to the moving plate.
[0012] As a further technical solution of the present utility model, bearing wheels or partitions are fixedly installed on the upper surface of the bottom plate.
[0013] The beneficial effects of the present utility model are as follows: The present utility model combines a cargo loading device and a goods pushing device, and together with a cargo blocking device, it can efficiently load long strip-shaped goods. The cargo blocking device prevents the scattered goods from falling, and the entire carriage of goods can be loaded at one time. The setting of the telescopic arm enables the present utility model to be applicable to goods of different lengths. The present utility model avoids loading and unloading goods by opening the top or side of the carriage, saving time and effort. The alignment device and the lifting oil cylinder can quickly align the loading and unloading device with the carriage opening, greatly reducing the driver's actions of moving the vehicle to align multiple times and saving time.
