Description

Technical Field

[0001] This utility model relates to the technical field of cargo transportation equipment, and in particular to a cargo loading and unloading equipment for port logistics. Background Technology

[0002] Port cargo transportation involves a wide variety of goods, commonly including boxed and bagged cargo. The general method of cargo transportation is to load goods onto trucks, which then transport them outwards. Loading and unloading processes typically employ both manual and mechanical methods. Manual handling involves people carrying goods directly from the ground or flatbed trucks into the truck bed, while mechanical handling utilizes methods such as crane lifting.

[0003] Manual handling is time-consuming and labor-intensive for workers, while mechanical handling is costly when transporting small quantities or small items. Therefore, there is a need to design a cargo loading and unloading equipment that has low operating costs and reduces the labor intensity of operators, so as to facilitate flexible use.

[0006] A cargo loading and unloading equipment for port logistics includes a frame, a lifting frame that slides vertically inside the frame, a pulley block for rolling support of the frame on the side of the lifting frame, a winch for raising and lowering the lifting frame at the top of the frame, the frame being raised and lowered vertically by a lifting mechanism, and a traveling mechanism at the bottom of the frame.

[0007] By adopting the above technical solution, the equipment is convenient for mobile transportation, easy for handling cargo transportation, saves time and effort for operators, has low operating costs, can adapt to the needs of unloading points at different heights, and plays a significant auxiliary role in the cargo transportation process.

[0008] Optionally, the frame includes a base, with four legs fixed in a matrix on the bottom surface of the base, and four outer columns fixed in a matrix on the top surface of the base.

[0009] By adopting the above technical solution, the inner column can move up and down relative to the outer column under the action of the lifting mechanism, thereby changing the range of vertical movement of the lifting frame to adapt to unloading points of different heights.

[0010] Optionally, the inner column has a vertical groove on its side, the outer column has a U-shaped cross-section, the pulley block is set in the groove or the U-shaped groove of the outer column, the lifting mechanism includes a crossbeam fixed horizontally between two adjacent inner columns, and a hydraulic cylinder is vertically installed on the top surface of the base, the top of the piston rod of the hydraulic cylinder is connected to the crossbeam.

[0011] By adopting the above technical solution, the hydraulic cylinder extends and retracts to drive the crossbeam to move, and the crossbeam drives the inner column to move, thereby realizing the lifting and lowering of the inner column.

[0012] Optionally, the walking mechanism includes two hydraulic cylinders that are vertically installed at the four corners of the top surface of the base. The piston rod of the two hydraulic cylinders slides through the base, and a roller is installed at the bottom end of the piston rod.

[0014] Optionally, the walking mechanism also includes a connecting plate fixed to the side wall of the outer column, with a rotating shaft rotatably connected between the connecting plates, and a U-shaped handrail fixed between the two rotating shafts. The connecting plate is provided with a limiting component for fixing the position of the handrail.

[0015] By adopting the above technical solution, when it is necessary to use the handrail to move the device, the handrail can be flipped to a horizontal state and fixed with the limiting component. When the handrail is not needed, the handrail can be flipped downward to a vertical state and fixed with the limiting component.

[0034] A pulley block 5 is installed at each of the four corners of the base plate 20 and the top plate 22. The pulley block 5 is used to roll in contact with the outer column 12 or the inner column 13. Taking the pulley block 5 located on the base plate 20 as an example, the pulley block 5 includes two ear plates 50 fixed to the base plate 20. A pin 51 is fixed between the two ear plates 50. Two rocker arms 52 are rotatably connected to the pin 51. The two rocker arms 52 are symmetrically arranged on the upper and lower sides of the horizontal line. A movable wheel 53 is rotatably connected to the end of the rocker arm 52 away from the pin 51. A tension spring 54 is connected between the upper and lower rocker arms 52. The movable wheel 53 rolls in contact with the slide groove 130 or the inner wall of the outer column 12.

[0035] The frame 1 is also equipped with a walking mechanism 6, which includes hydraulic cylinders 60 installed vertically at the four corners of the top surface of the base 10. The piston rod of the hydraulic cylinder 60 slides through the base 10 and a roller 61 is installed at the end of the piston rod. The roller 61 is used to contact the ground and support the base 10. Two connecting plates 62 are vertically fixed to the outer wall of each outer column 12. A rotating shaft 63 is installed horizontally between the two connecting plates 62. The rotating shaft 63 passes through the connecting plate 62 and is rotatably connected to the connecting plate 62. A U-shaped handrail 64 is fixed between two adjacent rotating shafts 63.

A pull rod 657 is vertically fixed to the surface of the C-shaped clip 654.

[0037] The implementation principle of the cargo loading and unloading equipment for port logistics in this embodiment of the present invention is as follows: The cargo loading and unloading equipment in this embodiment of the present invention can be operated by two operators. One operator is located on the ground and the other operator is located on the truck bed. The operator on the ground moves the cargo into the lifting frame 2, controls the winch 3 to lift the lifting frame 2 to the height of the truck bed, and then the operator on the truck bed takes down the cargo and controls the winch 3 to lower the lifting frame 2. The above steps are repeated.

[0038] The operator can move the equipment via the walking mechanism 6, control the extension of the hydraulic cylinder 60 to make the roller 61 contact the ground and the outrigger 11 lift off the ground, and move the equipment via the handrail 64. After moving to the position, control the extension of the hydraulic cylinder 60 to make the roller 61 lift off the ground and the outrigger 11 contact the ground, so that the equipment is stably supported on the ground for operation; the operator can rotate the handrail 64 by pulling the lever 657 to disengage the C-type clip 654 from the cross clip 650, so as to facilitate the use or storage of the handrail 64. Under the drive of the compression spring 656, the C-type clip 654 can automatically and stably lock onto the cross clip 650 to restrict the rotation of the handrail 64.

[0039] The upper and lower movable wheels 53 in the pulley block 5 are stably in contact with the outer column 12 or the slide 130 under the action of the tension spring 54, and under the guidance of the inclined plane 131, the lifting frame 2 is raised and lowered stably. When it is necessary to adapt to the truck bed or unloading point at different heights, the operator can control the hydraulic cylinder 41 to extend and retract the crossbeam 40, thereby driving the inner column 13 to rise and fall, so as to adjust the range of motion of the lifting frame 2 in the height direction.

[0040] This equipment is easy to move and transport, convenient to operate and transport goods, saves time and effort for operators, has low operating costs, and can be adapted to the needs of unloading points at different heights, playing a significant auxiliary role in the process of transporting goods.

[0041] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
