Description

Technical Field

[0001] This invention relates to the field of loading and unloading machinery technology, specifically a mobile dock loading and unloading telescopic belt conveyor. Background Technology

[0002] Traditional telescopic belt conveyors can freely extend and retract along their length, allowing for real-time control of the conveyor's length. They can operate in both directions to transport materials and can be used in conjunction with other conveying equipment and material sorting systems to automate material entry and exit from warehouses or vehicle loading and unloading. They are widely used in various industries. The use of telescopic belt conveyors shortens the distance that manual material handling can cover, reduces loading and unloading time, lowers labor intensity, reduces product damage, lowers loading and unloading costs, and improves work efficiency. Telescopic belt conveyors were first used in logistics, express delivery, and the tobacco industry. Here, we propose a new type of telescopic belt conveyor.

[0003] Most existing telescopic belt conveyors are fixed planar conveyor structures, mounted on concrete or steel platforms, with their tails connected to the assembly line. When container trucks enter the station for loading and unloading, the power button is pressed to start the machine. After the goods are placed on the telescopic belt conveyor, they are transported by the belt in both forward and reverse directions, thus achieving fixed loading and unloading. Conventional telescopic belt conveyors can only realize their performance advantages when used in fixed locations and connected to a dedicated belt line.

[0004] To solve the above problems, we urgently need a mobile dock loading and unloading telescopic belt conveyor. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a mobile dock loading and unloading telescopic belt conveyor to solve the problems mentioned in the background art, where existing telescopic belt conveyors are mostly fixed planar conveying structures, fixed on cement platforms or steel platforms, with their tails connected to the assembly line. Furthermore, conventional telescopic belt conveyors can only be used in fixed locations and can only realize their performance advantages when connected to a belt line.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mobile dock loading and unloading telescopic belt conveyor, comprising a mobile chassis, the mobile chassis being connected to a body assembly via pins, a first lifting cylinder being movably connected to the lower side of the body assembly via pins, a second lifting cylinder being movably connected to the left side of the lower side of the body assembly away from the first lifting cylinder via pins, the right side of the second lifting cylinder being movably connected to a fixed frame assembly, the fixed frame assembly being connected to the telescopic frame assembly via telescopic chains, a front-end control assembly being provided at the left end of the telescopic frame assembly, a belt drive assembly being provided at the right end of the body assembly, and a telescopic drive assembly being provided at the right end of the fixed frame assembly. Preferably, the first lifting cylinder is movably connected to the mobile chassis via a pin.

[0007] Preferably, a conveyor belt is fitted onto the outer surface of the body assembly, and a conveyor belt is also fitted onto the outer surface of the fixed frame assembly and the telescopic frame assembly.

[0008] Preferably, the mobile chassis is provided with four sets of screws around its perimeter, and the outer surfaces of the four sets of screws are threaded with adjustable heavy-duty feet. The mobile chassis is also provided with four brakeable casters on its underside.

[0009] Preferably, a main electrical control box is located on the left side of the mobile chassis, and a hydraulic lifting power assembly is located in the middle of the mobile chassis.

[0010] Compared with the prior art, the beneficial effects of the present invention are: This mobile dock loading and unloading telescopic belt conveyor, with its mobile design, can be flexibly moved to the location where goods need to be loaded and unloaded. It can be applied to factories, docks, shopping malls, logistics distribution centers, and other places. Through the cooperation of No. 1 and No. 2 lifting cylinders, fixed frame assembly, telescopic frame assembly, telescopic drive assembly, and belt drive assembly, the equipment can be extended and the transport angle can be adjusted, thus enabling large-angle tilting loading and unloading operations. It solves the problem of height differences in the stacked goods. When goods need to be loaded and unloaded, the equipment only needs to be moved to a suitable position to carry out loading and unloading operations, which greatly overcomes the shortcomings of conventional telescopic belt conveyors that cannot be used due to site limitations.

Detailed Implementation

[0013] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0014] Referring to Figures 1-4, in order to address the problem that most existing telescopic belt conveyors are fixed planar conveying structures, fixed on cement platforms or steel platforms, with their tails connected to flowing water, and that conventional telescopic belt conveyors can only be used in fixed locations and can only achieve their performance advantages when connected to belt lines, the present invention connects the movable chassis 1 to the machine body assembly 2 via pins. A first lifting cylinder 7 is movably connected to the lower side of the machine body assembly 2 via pins. A second lifting cylinder 8 is movably connected to the left side of the lower side of the machine body assembly 2, away from the first lifting cylinder 7, via pins. The right side of the second lifting cylinder 8 is movably connected to the fixed frame assembly 3. The fixed frame assembly 3 is connected to the telescopic frame assembly 4 via a telescopic chain 10. A front-end control assembly 13 is located at the left end of the telescopic frame assembly 4, a belt drive assembly 5 is located at the right end of the machine body assembly 2, and a telescopic drive assembly 9 is located at the right end of the fixed frame assembly 4.

[0015] Working Principle: When using this mobile dock loading and unloading telescopic belt conveyor, the equipment is moved to the work site, and four hydraulic fixing columns are deployed for fixation. Then, the equipment is adjusted according to the required work scenario. The first lifting cylinder 7 pushes the body assembly 2 up to the required position, and then the second lifting cylinder 8 pushes the fixed frame assembly 3 to the required position. The telescopic drive assembly 9 is activated, driving the telescopic chain 10 to move and extend the telescopic frame assembly 4 to the required position. Then, the belt drive assembly 5 is activated, driving the conveyor belt 11 to operate. Workers at the input end only need to place the items on the running belt, and workers at the output end only need to use their hands to remove the items from the conveyor belt 11 and stack them in pallets or carriages. The equipment can perform large-angle tilting loading and unloading operations through the first lifting cylinder 7 and the second lifting cylinder 8, thus solving the problem of height difference in the stacking position of goods. When goods need to be loaded and unloaded, the equipment only needs to be moved to the appropriate position for loading and unloading operations. At the same time, this equipment can be used alone or connected with other belt lines, making it highly adaptable.

[0016] Compared with related technologies, the mobile dock loading and unloading telescopic belt conveyor provided by the present invention has the following advantages: It adopts a mobile design, allowing for flexible movement to the location where loading and unloading of goods is required. It can be applied to factories, docks, shopping malls, logistics distribution centers, and other locations. Furthermore, the equipment can perform large-angle tilting loading and unloading operations via lifting cylinder 7 and lifting cylinder 8, thus solving the problem of height differences in cargo stacking positions. The equipment can be used independently or connected with other belt conveyors, demonstrating excellent applicability.

[0017] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
